Objetivo
El objetivo del presente proyecto es la búsqueda sistemática y exhaustiva de la
evidencia científica existente para la elaboración de una guía basada en la
evidencia para la mejora del manejo clínico, de determinación de contingencia y
de valoración médica de la incapacidad de los Nódulos de las cuerdas vocales a
causa de los esfuerzos sostenidos de la voz por motivos profesionales.
3
Estrategias de búsqueda
Se define la pregunta de investigación, la traducción al lenguaje documental, y el
diseño y desarrollo de filtros metodológicos que aumenten la calidad de las
búsquedas en cuanto a exhaustividad y precisión.
Definición de la pregunta de investigación
Evidencia científica sobre el manejo clínico, determinación de contingencia y
valoración médica de la incapacidad de los nódulos de las cuerdas vocales a
causa de esfuerzos sostenidos de la voz por motivos profesionales.
Traducción al lenguaje documental
Transformación de la pregunta de investigación en pregunta estratégica a través
de la pregunta PICO1, identificando los términos y combinación de los mismos, y
determinando la utilización de límites (geográficos, temporales, etc.) y uso de
filtros metodológicos.
Identificación de términos
Se realizó una búsqueda preliminar, muy precisa, con texto libre y limitada al título
de las publicaciones, para la identificación de los términos iniciales. Fueron los
siguientes:
pathological voice; voice disorders; voice loss; voice therapy; occupational
diseases; voice professionals; vocal professions; professional singers;
Identificación de una serie de componentes para la búsqueda bibliográfica:
1
Patients (pacientes o población de estudio), Intervention (Intervención y tipo de
intervención), Comparison (comparador), y Outcomes (resultados)
4
speech professions; teachers; vocalist; speech occupations; teachers;
occupational voice disorders; vocal cords; vocal apparatus; vocal cord
paralysis; vocal cord nodes; vocal fold nodules; nodose formations; kissing
nodules; vocal nodules
5
Diseño de estrategias
Se ha diseñado y desarrollado una estrategia general y posteriormente se ha
adaptado a cada recurso de información seleccionado en función de:

Base de datos general / específica (cobertura temática)

Extensión de la base de datos (cantidad de referencias bibliográficas)

Existencia de tesauro o lenguaje controlado

Lengua (de las referencias bibliográficas)
Límites
Los límites utilizados han sido los siguientes:

Lengua de las publicaciones: no se han establecido límites.

Fecha de publicación: no se han establecido límites en fechas de
publicación.

Población de estudio: personas con profesiones en las que utilizan la voz
como herramienta de trabajo: profesores, cantantes, etc.
Filtros metodológicos de búsqueda
Algunas bases de datos bibliográficas que se han consultado para la recuperación
de la literatura científica contienen un gran número de referencias bibliográficas,
como el caso de Medline (más de 20 millones) o Embase (cerca de 24 millones).
El resultado en estas fuentes de información suele ser exhaustivo, aunque
acompañado frecuentemente de excesivo ruido documental (elevado número de
referencias bibliográficas no relevantes).
Para la búsqueda en las bases de datos generales seleccionadas, se han utilizado
filtros metodológicos temáticos con la finalidad de aumentar la especificidad o
6
sensibilidad en su resultado.
Estos filtros metodológicos han consistido en la combinación de una serie de
términos (en su mayoría descriptores) relacionados con la Medicina del Trabajo.
Se ha tomado como base el filtro metodológico creado por Sanz-Valero J, et al.
con el fin de conocer la producción científica española sobre Medicina del Trabajo
en la base de datos MEDLINE2. Ha sido modificado buscando un resultado más
exhaustivo; entre otras modificaciones la de sustituir la propiedad de Major topic
(grupo de descriptores principales de una referencia) por la de Descriptor simple
(descriptor del documento sin necesidad de ser una de sus materias principales),
también añadir y/o eliminar algunos de los términos con el fin de adaptarlos a cada
recurso de información específico.
El filtro metodológico base adaptado y desarrollado ha sido el siguiente:
“Occupational Health Services” OR “Occupational Health Nursing” OR
“Occupational Health Physicians” OR “Occupational Exposure” OR
“Occupational Therapy” OR “Occupational Medicine” OR “Occupational
Dentistry” OR “Occupational Diseases” OR “Noise, Occupational” OR
“Occupational Health”
OR “Occupational Therapy Department, Hospital”
OR “Dermatitis, Occupational” OR “Accidents, Occupational” OR “Air
Pollutants, Occupational”
Para su utilización en las base de datos ha sido necesaria su adaptación al
lenguaje controlado de cada una de ellas. En las estrategias de búsquedas
incluidas en el Anexo 1 se especifica detalladamente.
“Los filtros metodológicos: aplicación a la búsqueda bibliográfica en la medicina
2
del trabajo española”. Sanz-Valero J, et al. Med Segur Trab 2008; (LIV)211:75-83.

Bases de datos utilizadas
Se ha desarrollado un protocolo para la selección de los recursos de información
consistente en:

Identificación de las bases de datos.

Jerarquizar las bases de datos y establecer un orden de preferencias.
Se ha tomado como base el protoloco propuesto por Güemes en Desarrollo de
protocolos de búsqueda bibliográfica de la literatura adaptándolos a los diferentes
productos de evaluación3 y que se incorpora en este documento como Anexo 2.
Dicha propuesta se basa a su vez en el protocolo COSI creado por la agencia
neozelandesa NZHTA (New Zealand Health Technology Assessment) y DACEHTA
(Danish Centre for Evaluation and Health Technology Assessment) y que consiste
en una aproximación para seleccionar las fuentes de información relevantes entre
tres agrupaciones de bases de datos dependientes de la relevancia de las bases
de datos y tiempo marco dispoble para el acceso: búsqueda Core, Standard e
Ideal.
Se han tenido en cuenta una serie de factores entre los que se encuentran el tema
de estudio, la tipología de estudios por su metodología a recuperar, accesibilidad
de los recursos de información y documentos a texto completo, o las coberturas
geográficas y temporales. Con todo ello, la selección de fuentes de información a
consultar ha sido la siguiente:
Güemes Careaga I, Gutiérrez Ibarluzea I y el grupo AUnETS de documentación.

Selección de referencias
Realizada la búsqueda sistemática de la bibliografía, se procede a la lectura crítica
de los documentos.
Una primera lectura de la referencia bibliográfica completa (siempre que tenga
abstract) permite a través de los criterios de exclusión previamente establecidos
descartar un grupo de documentos poco o nada relevantes. Este grupo de
documentos es mayor o menor en función del tipo de búsqueda, las bases de
16
datos consultadas y el tema tratado.
La búsqueda para el presente proyecto ha contado con las siguientes
peculiaridades:

Pregunta de investigación acotada al área de la medicina del trabajo:
enfoque en enfermedad/es profesional/es.

Selección de recursos de información específicos de un área determinada y
no prefiltrados, menos sistemáticos en estructura y calidad del contenido.

Consulta a portales de información, también peor estructurados y con
menos contenido.
Todo ello ha hecho que el grupo de referencias posibles a descartar con criterios
de exclusión en una primera lectura de título y abstract sea pequeño, habiendo
sido necesario la obtención del los documentos originales y la lectura a texto
completo de la mayor parte de los mismos.
Además de la búsqueda bibliográfica de manera sistemática ya automatizada, ha
habido una búsqueda manual a partir de las referencias consultadas.

Amour J, Le-Manach YL, Borel M et al. Comparison of single-use and reusable
metal laryngoscope blades for orotracheal intubation during rapid sequence
induction of anesthesia: a multicenter cluster randomized study.
Anesthesiology 2010;112:325-332.
Ref ID: 429
Abstract: BACKGROUND: Single-use metal laryngoscope blades are cheaper
and carry a lower risk of infection than reusable metal blades. The authors
compared single-use and reusable metal blades during rapid sequence
induction of anesthesia in a multicenter cluster randomized trial. METHODS:
One thousand seventy-two adult patients undergoing general anesthesia
under emergency conditions and requiring rapid sequence induction were
randomly assigned on a weekly basis to either single-use or reusable metal
blades (cluster randomization). After induction, a 60-s period was allowed to
complete intubation. In the case of failed intubation, a second attempt was
performed using the opposite type of blade. The primary endpoint was the
rate of failed intubation, and the secondary endpoints were the incidence of
complications (oxygen desaturation, lung aspiration, and/or oropharynx
trauma) and the Cormack and Lehane score. RESULTS: Both groups were
similar in their main characteristics, including the risk factors for difficult
intubation. The rate of failed intubation was significantly decreased with
single-use metal blades at the first attempt compared with reusable blades
(2.8 vs. 5.4%, P < 0.05). In addition, the proportion of grades III and IV in
Cormack and Lehane score were also significantly decreased with single-use
metal blades (6 vs. 10%, P < 0.05). The global complication rate did not
reach statistical significance, although the same trend was noted (6.8% vs.
11.5%, P = not significant). An investigator survey and a measure of
illumination pointed that illumination might have been responsible for this
result. CONCLUSIONS: The single-use metal blade was more efficient than a
reusable metal blade in rapid sequence induction of anesthesia

dysphonia severity index. J Voice 2010;24:661-666.
Ref ID: 10
Abstract: The purposes of this study were (1) to compare trained and
untrained singers on the Dysphonia Severity Index (DSI) and its component
measures, and (2) to contribute to normative DSI data for trained singers.
This study included 36 untrained participants (15 males and 21 females) and
30 participants (15 males and 15 females) with singing experience between
the ages of 18 and 30 years. Measures of maximum phonation time (MPT),
highest phonational frequency, lowest intensity, and jitter were obtained for
each subject and incorporated into the previously published multivariate DSI
formula. Results indicated that vocally trained subjects have significantly
higher DSI scores than untrained subjects (mean DSI: 6.48 vs 4.00,
respectively), with significant differences observed between trained and
untrained groups for three of the four components of the DSI (F(0) high; I
low; jitter). The findings of this study are consistent with previous reports
that indicate significant increases in the DSI with vocal training, and with
various studies that have observed increased vocal capability in trained
singers versus their untrained counterparts. The results of this study indicate
that alternative normative expectations for the DSI may need to be taken into
account when using the DSI with patients who have participated in directed
vocal training, such as choral participation and voice/singing lessons

Ref ID: 9
Abstract: OBJECTIVES: To examine the impact of voice on the quality of life of
teachers and to assess whether the degree of dysphonia and
otorhinolaryngologists' (ORL) diagnostics are correlated with the quality of
life. METHODS: Eighty-eight female teachers from the municipal schools of
Belo Horizonte who were in speech therapy at the Speech Therapy Clinic of
the Hospital das Clinicas of Minas Gerais participated in the study. The
variables studied were age, ORL diagnosis, perceptual-hearing assessment of
voice through GRBAS scale, and vocal activities and participation profile
(VAPP) protocol. Statistical analysis was performed through the descriptive
analysis of the data and the Spearman coefficient of correlation. RESULTS:
The average age of the participants was 38 years. Vocal deviation: degree 156 teachers (63.6%); degree 2-27 teachers (30.6%); and without vocal
deviation-five teachers (5.6%). It was found that 57.9% of the teachers
presented combined ORL diagnosis. No statistically significant relationship
was observed among the ORL diagnosis, the degree of dysphonia, and the
parameter values of quality of life assessed by VAPP. CONCLUSIONS: The
examined participants of this study presented light degree of vocal deviation
and ORL combined diagnosis. According to the figures obtained by VAPP, there
was negative impact of voice on the quality of life of female teachers, but
these impacts were not correlated with ORL diagnosis and grade of dysphonia

Vocal Use, Risk Factors, and Voice Disorder Prevalence: Guidelines to Detect
Teachers with Current Voice Problems. Folia Phoniatr Logop 2010;63:209215.
Ref ID: 3
Abstract: Teachers' voice problems are widely recognized as a consequence of
their work. The measurement of vocal demands and risk factors is essential
for adjusting occupational safety and health services to this population's
needs. Objectives: To correlate vocal behavior and symptomatology with risk
factors and voice disorders, and to further analyze gender influence on these
variables. Subjects and Methods: 282 kindergarten and elementary education
teachers were surveyed in a cross-sectional study using a self-administered
questionnaire. For the purpose of this study, voice disorder prevalence was
estimated based on the presence of a vocal effort plus 2 frequent symptoms.
Results: 81.5% of teachers reported some degree of vocal effort; more than
60% of subjects evidenced frequent throat paresthesias or vocal fatigue at
the end of a working day, and about 55% reported hoarseness. Voice disorder
prevalence was 59%. Multivariate logistic regression analysis revealed that
female gender, time required to alleviate vocal symptoms, perceived general
state of health, prolonged use of the voice, and pupils' indiscipline
significantly increased the odds of having vocal problems. Conclusions: Voice
disorders affected most teachers and had a multifactorial nature. Vocal health
care is particularly necessary for those subjects reporting vocal effort and
more than 2 frequent symptoms

Ref ID: 431
Abstract: BACKGROUND: Reducing weaning time is desirable in minimizing
potential complications from mechanical ventilation. Standardized weaning
protocols are purported to reduce time spent on mechanical ventilation.
However, evidence supporting their use in clinical practice is inconsistent.
OBJECTIVES: To assess the effects of protocolized weaning from mechanical
ventilation on the total duration of mechanical ventilation for critically ill
adults; ascertain differences between protocolized and non-protocolized
weaning in terms of mortality, adverse events, quality of life, weaning
duration, intensive care unit (ICU) and hospital length of stay (LOS); and
explore variation in outcomes by type of ICU, type of protocol and approach
to delivering the protocol. SEARCH STRATEGY: We searched the Cochrane
Central Register of Controlled Trials (The Cochrane Library Issue 1, 2010),
MEDLINE (1950 to 2010), EMBASE (1988 to 2010), CINAHL (1937 to 2010),
LILACS (1982 to 2010), ISI Web of Science and ISI Conference Proceedings
(1970 to 2010), Cambridge Scientific Abstracts (inception to 2010) and
reference lists of articles. We did not apply language restrictions. SELECTION
CRITERIA: We included randomized and quasi-randomized controlled trials of
protocolized weaning versus non-protocolized weaning from mechanical
ventilation in critically ill adults. DATA COLLECTION AND ANALYSIS: Three
authors independently assessed trial quality and extracted data. A priori
subgroup and sensitivity analyses were performed. We contacted study
authors for additional information. MAIN RESULTS: Eleven trials that included
1971 patients met the inclusion criteria. The total duration of mechanical
ventilation geometric mean in the protocolized weaning group was on average
reduced by 25% compared with the usual care group (N = 10 trials, 95% CI
9% to 39%, P = 0.006); weaning duration was reduced by 78% (N = 6 trials,
95% CI 31% to 93%, P = 0.009); and ICU LOS by 10% (N = 8 trials, 95% CI
2% to 19%, P = 0.02). There was significant heterogeneity among studies for
total duration of mechanical ventilation (I2 = 76%, P < 0.01) and weaning
duration (I2 = 97%, P < 0.01), which could not be explained by subgroup
analyses based on type of unit or type of approach. AUTHORS'
CONCLUSIONS: There is some evidence of a reduction in the duration of
mechanical ventilation, weaning duration and ICU LOS with use of
standardized protocols, but there is significant heterogeneity among studies
and an insufficient number of studies to investigate the source of this
heterogeneity. Although some study authors suggest that organizational
context may influence outcomes, these factors were not considered in all
included studies and therefore could not be evaluated. THE USE OF
STANDARDIZED PROTOCOLS IN WEANING COMPARED TO USUAL WEANING
PRACTICE FOR REDUCING THE TIME CRITICALLY ILL ADULT PATIENTS SPEND
ON MECHANICAL VENTILATION: Helping patients to breathe with the use of a
mechanical ventilator can be life saving. Yet as the duration of ventilation
increases so does the likelihood of harmful effects such as (1) mechanical
3
injury to the throat or vocal cords, (2) injury to or infection of the lungs and
(3) complications of prolonged patient immobility such as clots in the legs or
lungs and various infections (for example in the urinary tract). It is important
therefore to recognize straight away when patients are ready to breathe for
themselves so that the ventilator support can be reduced and stopped (this is
known as weaning) as soon as possible. Usually weaning decisions are left to
the judgement of the staff but recently protocols (or written guidelines) for
weaning have been found to be both safe for patients and useful for staff.
Some studies claimed that using protocols led to better practice, but there
was no clear evidence that using them actually produced beneficial results for
patients.This review looked at the results of 11 studies involving 1971
critically ill patients. The studies compared the use of protocols to wean
patients from the ventilator against usual practice and were conducted in
America, Europe and Australia. The varied intensive care units cared for
patients with heart conditions, breathing difficulties, head injuries, trauma
and following major surgery. In eight studies, intensive care staff followed
protocol guidelines to reduce the ventilator support; in three studies
ventilator support was reduced by programmed computers according to a
protocol. Overall, results showed that in comparison with usual practice, the
average total time spent on the ventilator was reduced by 25%. The duration
of weaning was reduced by 78% and length of stay in the intensive care unit
reduced by 10%. However, these reductions were not consistent across all
studies.Among the 11 studies, there was considerable variation in the types of
protocols used, the criteria for considering when to start weaning, the
methods of weaning (by professionals or computers), the medical conditions
of the patients and usual practice in weaning. There were insufficient studies
to enable us to explore whether or not these factors were responsible for
inconsistencies in individual studies. Caution will need to be applied when
generalizing our findings to other intensive care units

Abstract: Phonosurgery is an effective treatment for some vocal fold
pathologies, and the Voice Handicap Index (VHI) survey has been shown to
be a useful instrument for evaluating treatment effectiveness. We conducted a
nonrandomized, prospective study of 21 patients who underwent
phonosurgery for the treatment of non-neoplastic vocal fold lesions at our
academic tertiary-care referral center. Our goals were to compare pre- and
postoperative VHI scores (subjective assessments) and pre- and
postoperative results of acoustic and aerodynamic tests (objective
assessments). We sought to determine if there was any correlation between
the subjective and objective findings. We looked for differences between
professional voice users (n = 10) and nonprofessional voice users (n = 11) in
both subjective and objective measures. We found statistically significant
differences between pre- and postoperative values in three of four VHI
parameters, but in only one of 13 objective measures. There was no
correlation between preoperative VHI scores and preoperative acoustic and
aerodynamic test results. The professional voice users expressed greater
postoperative improvement as reflected by lower VHI scores than did the
nonprofessional voice users, confirming that the former are more negatively
affected by a voice disability

Abstract: This study aimed to investigate the subjective health complaints
(SHC) in the teaching profession of Hong Kong. On the basis of the SHC
inventory, a questionnaire was prepared for data collection through a mail
survey. A total of 1710 usable questionnaires were returned by the primary or
secondary school teachers. The results showed that 99.5% (n = 1702) of
respondents suffered at least one type of the 39 single health problems on
the total SHC scale during the preceding 30 days. The 10 most frequently
reported health complaints among the teachers were tiredness, eyestrain,
anxiety, sleep problems, voice disorder, shoulder pain, neck pain, headache,
cold/flu, and lower-back pain. With the exception of the category of
pseudoneurological complaints, primary school teachers showed a statistically
higher prevalence in reporting problems in 6 of 7 subscales. The 5 most
severe complaints were tiredness, eyestrain, sleep problems, shoulder pain,

Abstract: Importance of the field: Dystonia is a neurological syndrome
characterized by involuntary twisting movements and unnatural postures. It
has many different manifestations and causes, and many different treatment
options are available. These options include physical and occupational
therapy, oral medications, intramuscular injection of botulinum toxins, and
neurosurgical interventions. Areas covered in this review: In this review, we
first summarize the treatment options available, then we provide suggestions
from our own experience for how these can be applied in different types of
dystonia. In preparing this review article, an extensive literature search was
undertaken using PubMed. Only selected references from 1970 to 2008 are
cited. What the reader will gain: This review is intended to provide the
clinician with a practical guide to the treatment of dystonia. Take home
message: Treatment of dystonia begins with proper diagnosis and
classification, followed by an appropriate search for underlying etiology, and
an assessment of the functional impairment associated with the dystonia. The
therapeutic approach, which is usually limited to symptomatic therapy, must
then be tailored to the individual needs of the patient

Teachers and Barriers to Care. J Voice 2010.
Ref ID: 2
Abstract: INTRODUCTION: Teachers have an increased prevalence of voice
disorders that result in reduced activities, missed workdays, and occupation
changes. However, only a small fraction of these teachers have sought
professional help for their disorders. The purpose of this study was to
elucidate some of the barriers to care that teachers may face. STUDY
DESIGN: Cross-sectional survey. METHODS: One thousand subjects were
randomly selected from a list of 95, 364 Kindergarten-12 teachers in North
Carolina. Teachers were mailed a 43-item survey, with domains including
demographics, personal voice health, and barriers to care using a five-point
Likert scale. Results were tabulated, and statistical analysis was performed
using the chi-square test. RESULTS: Two hundred forty-three responses were
5
received; 237 were complete. Twenty-two percent were currently hoarse.
Fifty-eight percent had been hoarse at one point. Twenty-three percent had
missed work for hoarseness. Only one-third (32.6%) had sought professional
help. Women and those older than 45 years were more likely to seek help
(P<0.001 and P=0.008, respectively). Fewer than half were aware of voice
therapy or believed that a doctor could help. Thirty percent believed that
hoarseness was normal in teaching. CONCLUSIONS: There are multiple
barriers to care for the dysphonic teacher, including the lack of awareness of
the availability of professional help. Further studies should evaluate teacher
education and reducing barriers to care

Abstract: OBJECTIVES: The goals of this epidemiological paper are focused on
studying teachers' vocal complaints, their voice pattern, and the impact of
voice disorders on psychosocial working conditions. PATIENTS: A
representative stratified random sample of 282 teachers from kindergartens
and elementary schools was studied. Two types of self-report questionnaires
were applied: an inquiry about teachers' occupational voice profile, and the
adapted Spanish version of the Copenhagen Psychosocial Questionnaire
(ISTAS-21). Pearson's chi(2) test was performed to search for statistical
associations. RESULTS: 62.7% of subjects were experiencing occupational
voice disorders; these teachers showed significantly worse psychosocial
conditions than their healthy voice colleagues. CONCLUSIONS: Occupational
voice disorders affect more than 60% of teachers and have an impact on their
psychosocial working conditions. Interdisciplinary work is essential to shed
light on these multifactor mechanisms and effects

Ref ID: 362
Abstract: OBJECTIVE: To evaluate published evidence of efficacy and safety of
pharmacologic treatments for childhood spasticity due to cerebral palsy.
METHODS: A multidisciplinary panel systematically reviewed relevant
literature from 1966 to July 2008. RESULTS: For localized /segmental
spasticity, botulinum toxin type A is established as an effective treatment to
reduce spasticity in the upper and lower extremities. There is conflicting
evidence regarding functional improvement. Botulinum toxin type A was
found to be generally safe in children with cerebral palsy; however, the Food
and Drug Administration is presently investigating isolated cases of
generalized weakness resulting in poor outcomes. No studies that met criteria
are available on the use of phenol, alcohol, or botulinum toxin type B
injections. For generalized spasticity, diazepam is probably effective in
reducing spasticity, but there are insufficient data on its effect on motor
function and its side-effect profile. Tizanidine is possibly effective, but there
are insufficient data on its effect on function and its side-effect profile. There
were insufficient data on the use of dantrolene, oral baclofen, and intrathecal
baclofen, and toxicity was frequently reported. RECOMMENDATIONS: For
localized/segmental spasticity that warrants treatment, botulinum toxin type
A should be offered as an effective and generally safe treatment (Level A).
There are insufficient data to support or refute the use of phenol, alcohol, or
botulinum toxin type B (Level U). For generalized spasticity that warrants
treatment, diazepam should be considered for short-term treatment, with
caution regarding toxicity (Level B), and tizanidine may be considered (Level
C). There are insufficient data to support or refute use of dantrolene, oral
baclofen, or continuous intrathecal baclofen (Level U). Copyright ® 2010 by

Abstract: Background: Animal-derived proteins are implicated in primary food
allergies, but also in inhalant allergies with secondary food allergy symptoms.
The objective of this study was to define the allergen(s) implicated in a case
of food allergy to chicken meat, which developed in a person previously
sensitized to pork after occupational exposure. Methods: A 42-year-old female
with a history of occupational inhalant allergy to pork reported rhinitis,
asthma, dysphonia and conjunctivitis 30 min after ingestion of chicken. Skin
tests were positive to chicken meat. Protein extracts were prepared from
chicken meat. Allergens were characterized by IgE immunoblotting, Nterminal sequencing and ELISA. Results: The patient showed specific IgE
binding to chicken meat proteins at 12, 14, 26, 55 and 65 kDa. N-terminal
amino acid sequencing identified the 12- and 14-kDa proteins as the alphaand beta-chain of hemoglobin. ELISA and immunoblot showed specific IgE
binding to hemoglobin purified from chicken blood. IgE antibodies to chicken
serum albumin were detected by ELISA. Inhibition studies with chicken and
porcine hemoglobin as well as with serum albumins demonstrated crossreactive IgE antibodies. Conclusions: We report a case of confirmed
occupational inhalant allergy due to pork followed by food allergy to pork and
3 years later by food allergy to chicken. Porcine and chicken hemoglobin were
found to be crossreactive allergens. Cross-reactivity between porcine and
chicken serum albumin was possibly linked to a prior sensitization to cat
serum albumin. Copyright ® 2009 S. Karger AG, Basel

Abstract: The authors describe a 38-year-old man who presented with
hypernasality, perioral and acroparesthesia, dyspnea, and dysphagia. Further
evaluation revealed a diagnosis of Miller-Fisher syndrome (MFS). MFS is a
variant of Guillain-Barrq syndrome previously described in neurology and
critical care journals; however, there is a paucity of work concerning this
disease in the otolaryngology literature. An acute change in voice usually
occurs secondary to inflammatory processes as seen after intubation and
infection, but can occur as part of a more complex disease entity such as
Guillain-Barrq or Miller-Fisher syndrome. As such, clinicians should consider
this in their evaluation of rhinolalia aperta. ® 2010 The American

Primary School Teachers in Hong Kong. J Occup Health 2010.
Ref ID: 4
Abstract: Objective: The purpose of the study was to investigate the
prevalence of voice disorders and associated risk factors among primary
school teachers in Hong Kong. Methods: A cross-sectional survey was
conducted based on a random sample of 20 primary schools in Hong Kong. A
total of 714 full-time primary school teachers were invited to participate in
the survey. Data were collected through a self-administered questionnaire
addressing the prevalence of voice disorders and potential risk factors.
Stepwise logistic regression was used to assess the associations between
voice disorders and the different risk factors. Results: The response rate for
the questionnaire was 69.7% (498/714). Among the teachers who responded,
348 (69.9%) had suffered from a voice disorder in the past 12 mo. Thirty-one
teachers (8.9%) rated their voice disorders as minimal, 124 (35.6%) as mild,
151 (43.4%) as moderate, and 42 (12.1%) as severe. Of the 348 teachers
reporting voice disorders, 215 (61.8%) had sought professional help for their
voice problems. The univariate analyses showed that the factors significantly
associated with voice disorders included talking quietly (p=0.018), using a
microphone (p=0.002), speaking against background noise (p<0.001),
consuming alcohol (p=0.027), and having a history of asthma (p=0.001),
colds (p=0.012), sinusitis (p=0.039), or laryngitis (p<0.001). After
adjusting for potential confounds, the significant risk factors included
speaking against background noise (adjusted OR=1.8), alcohol consumption
(adjusted OR=0.40), history of asthma (adjusted OR=3.3), or laryngitis
(adjusted OR=4.2). Conclusions: Approximately 70% of the sampled primary
school teachers were affected by voice disorders. A substantial proportion of
the effected teachers suffered both functional and psychological adverse
effects. The findings indicate an urgent need for further investigation to
identify the risk factors for voice disorders and to develop preventive
strategies for primary school teachers

Abstract: Voice is one of the most important instruments for expression and
communication in humans. Dysphonia remains very frequent. Generally
people in voice-intensive professions, such as teachers, call center
employees, singers and actors suffer from these complaints. In recent years
methods have been developed which facilitate appropriate diagnosis and
therapy, based on the criteria of evidence based medicine, in voice patients
appropriate to their degree of disease. The basic protocol of the European
Laryngological Society offers a standardized evaluation of multidimensional
voice parameters. In our own patient collective there were statistically
significant improvements in voice quality, according to a pre/post mean value
comparison, in both phonomicrosurgical (n=45) and voice therapy (n=30)

Teachers: Vocal Complaints, Treatment-Seeking Behavior, Knowledge of Vocal
Care, and Voice-Related Absenteeism. J Voice 2010.
Ref ID: 5
Abstract: OBJECTIVES: Teachers are at increased risk for developing voice
disorders. Occupational risk factors have been extensively examined;
however, little attention has been paid to the consequences of the vocal
complaints. The objective of this study was to investigate the knowledge that
teachers have about vocal care, treatment-seeking behavior, and voicerelated absenteeism. METHODS: The study group comprised 994 teachers
and 290 controls whose jobs did not involve vocal effort. All participants
completed a questionnaire inquiring about vocal complaints, treatmentseeking behavior, voice-related absenteeism, and knowledge about vocal
care. Comparisons were made between teachers with and without vocal
complaints and with the control group. RESULTS: Teachers reported
significantly more voice problems than the control population (51.2% vs
27.4%) (chi(2)=50.45, df=1, P<0.001). Female teachers reported
9
significantly higher levels of voice disorders than their male colleagues (38%
vs 13.2%, chi(2)=22.34, df=1, P<0.001). Teachers (25.4%) sought medical
care and eventually 20.6% had missed at least 1 day of work because of
voice problems. Female teachers were significantly more likely to seek
medical help (chi(2)=7.24, df=1, P=0.007) and to stay at home (chi(2)=7.10,
df=1, P=0.008) in comparison with their male colleagues. Only 13.5% of all
teachers received information during their education. CONCLUSIONS: Voice
disorders have an impact on teachers' personal and professional life and imply
a major financial burden for society. A substantial number of teachers needed
medical help and was obligated to stay at home because of voice problems.
This study strongly recommends the implementation of vocal education
during the training of teacher students to prepare the vocal professional user

Abstract: OBJECTIVE: To investigate the status of voice fatigue and throat
disease in the secondary school teachers in Urumqi. METHODS: This study
included 11 689 teachers from 109 secondary schools offered by Teaching and
Researching Center of Urumqi as the second-stage random sampling. Among
them, 3217 teachers were selected to carry out voice fatigue test and routine
examination of throat. For those with abnormal routine inspection results, the
stroboscopic laryngoscopy were added. RESULTS: The failure rate difference
of 3217 secondary school teachers voice fatigue tests during different periods
had statistical significance (F = 202.653, P < 0.05). The failure rate
difference of voice fatigue test among different throat diseases groups had
statistical significance (F = 9.516, P < 0.05). There was statistical
significance in failure rates of the voice fatigue tests between 908 cases of
disease group and 2309 cases of normal group among different genders and
periods (P < 0.05). Female teachers had higher failure rates than male
teachers in voice fatigue tests. High failure rates appeared when high volume
required for male and female teachers in voice fatigue tests. There was
statistical significance in mean value sound pressure level (MVSPL) and mean
value fundamental frequency (MVF0) of the voice fatigue tests between
different gender and periods (P < 0.05). Male teachers had higher MVSPL
than female teachers, female teachers had higher MVF0 than male teachers.
There was statistical significance in failure rates of the voice fatigue tests
among teachers from different tribes in different periods (P < 0.05). The
Uighur had the highest failure rate, while Han had the lowest. Make further
pairwise comparisons, failure rates difference of the Han and the Uighur in the
voice fatigue tests during different periods had statistical significance.
Comparison among other tribes had no statistical significance (P > 0.05).
CONCLUSIONS: Voice fatigue is common in secondary school teachers.
Female teachers tend to get voice fatigue more easily, when required high
volume, the voice fatigue is more serious. Uighurs teachers have highest
degree of voice fatigue

Abstract: INTRODUCTION: The purpose of this paper is to review the
literature on the behavioral treatment of voice disorders in teachers. The
focus is on phonogenic disorders, that is voice disorders thought to be caused
by voice use. METHODS: Review of the literature and commentary. RESULTS:
The review exposes distinct holes in the literature on the treatment of voice
problems in teachers. However, emerging trends in treatment are noted. For
example, most studies identified for review implemented a multiple-therapy
approach in a group setting, in contrast to only a few studies that assessed a
single-therapy approach with individual patients. Although the review reveals
that the evidence around behavioral treatment of voice disorders in teachers
is mixed, a growing body of data provides some indicators on how effectively
rehabilitation of teachers with phonogenic voice problems might be
approached. Specifically, voice amplification demonstrates promise as a
beneficial type of indirect therapy and vocal function exercises as well as
resonant voice therapy show possible benefits as direct therapies. Finally, only
a few studies identified even remotely begin to meet guidelines of the
Consolidated Standards of Reporting Trials statement, a finding that
emphasizes the need to increase the number of investigations that adhere to
strict research standards. CONCLUSIONS: Although data on the treatment of
voice problems in teachers are still limited in the literature, emerging trends
are noted. The accumulation of sufficient studies will ultimately provide useful
evidence about this societally important issue

voice disorders in teachers. J Prev Med Hyg 2009;50:26-32.
Ref ID: 16
Abstract: INTRODUCTION: In Italy the number of teachers among private and
public schools is around one million. Voice disorders are thought to be one of
the major occupational hazards of school teaching; in fact the teachers often
use their voice with high-intensity, in noisy classes, for a long time and
without suitable breaks. The aim of the study was to assess the prevalence of
voice problems in teachers of Naples district, identifying risk factors for
developing voice pathology. METHODS: In this study we evaluated 504
teachers (322 F-182 M) with an age ranging between 24 and 62 years,
randomly choiced in 28 schools of the district of Naples submitted to a
questionnaire to determine the prevalence of voice disorders. In our study we
have also introduced a comparison group of not-teachers workers of 402
subjects (244 F-158 M); they were in the same age range as the teacher
sample (range: 22-65 years). The control group was also submitted to a
questionnaire regarding sociodemographic characteristics, smoking and
alcohol use, a self-report of voice problems, voice symptoms, frequency of
acute and chronic voice problems, absenteeism due to voice problems.
RESULTS: The prevalence of reporting a current voice problem was
significantly greater in teachers compared with not-teachers (8.7% vs 2.9%),
as the prevalence of voice disorders during their lifetime too (51.4% vs
25.9%), chi2 = 86.672, p < 0.001. Women, compared with men had a
higher lifetime prevalence of voice disorders. An other important data
evidenced, is that 116 workers of the teachers group (23.01%) have been
forced, during their professional activity, to miss job for problems related to
voice; only 22 subjects of control group (5.47%) instead, missed job for voice
troubles. DISCUSSION AND CONCLUSIONS: This study confirms that teachers
have a higher rate of self-reported voice problems than subjects working in
other occupations. Teachers, compared with not-teachers, were significantly
more likely to have experienced multiple voice symptoms including
hoarseness, discomfort while using their voice, difficulty projecting their voice
and tiring or change in voice quality after short use. Large proportion of these
problems may be preventable and prevention programs need to be developed
and evaluated. Italian teachers do not receive any preventive voice training;
that, in combination with poor hygienic work conditions, could increase health
problems. Thus, voice training of teachers and teacher college students in
some cases should be considered as a useful tool to prevent voice disorders

Ref ID: 20
Abstract: PURPOSE: This article presents the current state of knowledge
regarding vocal hygiene for the voice professional. RECENT FINDINGS:
Research regarding vocal hygiene has primarily focused on two areas: vocal
hygiene as a preventive strategy, and vocal hygiene as a management
technique for individuals with voice disorders. It is difficult to assess the
effectiveness of vocal hygiene as a preventive tool as programs are often
expensive leading to limited data. Vocal hygiene as a sole strategy for the
treatment of voice disorders has shown minimal, but favorable results. As a
component of a comprehensive therapeutic program, it is difficult to isolate
the influence of vocal hygiene. However, limited components of vocal hygiene
including hydration and vocal rest have been associated with improved
therapeutic outcomes. In addition, the current literature proposes a paradigm
shift away from more restrictive therapy approaches to a holistic approach to
vocal well being. SUMMARY: Vocal hygiene should be considered only as a
component of a broad vocal rehabilitation program. The role of vocal hygiene
as a means to prevent voice disorders remains unproven. Additionally, some
of the findings may be applied to both dysphonic and healthy individuals in
order to facilitate vocal well being

Abstract: A questionnaire investigating the levels of interest in and knowledge
of vocal function and dysfunction was completed by 129 singers. Those with
professional singing experience indicated significantly greater interest and
higher perceived knowledge levels than amateurs in areas of vocal anatomy
and physiology, vocal hygiene, and functional vocal pathologies. Greater
interest levels, but not higher perceived knowledge levels were reported by
professional singers (PSs) in the area of the role of the speech-language
pathologist (SLP) and the voice. Professionals answered significantly more
knowledge-based questions correctly than amateurs in all areas except the
role of the SLP and the voice. However, findings indicated wide variability in
knowledge levels of both groups. Singing teachers (STs) within the group
significantly outperformed the remainder of the group in areas of vocal
anatomy and physiology, vocal hygiene, and functional vocal pathologies.
Scores of the choir directors (CDs) within the group were not significantly
superior to the remainder of the group except in the area of functional vocal
pathologies. Implications for a preventative approach to vocal health are
discussed

Abstract: Purpose: The present study sought to assess the impact of
telephone call center employees' working conditions on health by identifying
at- risk employment situations. Methods: A transversal study was performed
13
in companies followed by 47 occupational physicians taking part (working
conditions have been previously described). A self- administered medical
questionnaire was used to collect data on absence due to sick leave, hearing
and visual problems, musculoskeletal disorders, psychotropic drug use, etc.
An analog-scale self-assessment of health status and a general health
questionnaire (GHQ-12) were used. Personal or familial events that might
underlie health problems and affect GHQ-12 results were quantified and taken
into account in a logistic regression. Results: A total of 2,130 call-handlers
were included. Workers who had availed sick leave during the previous 12
months were 60%. The most frequent musculoskeletal complaints over the
previous 12-month period concerned the cervical region (59%). During the
same period, 77.3% of subjects experienced visual fatigue, 50% reported
auditory fatigue signs and 47% vocal disturbance or fatigue. According to the
Likert scale, 39.4% of workers had showed psychological distress. Almost
24% of the workers had used psychoactive medication during the previous 12
months. A significant association was found between psychological distress
and the frequency of musculoskeletal disorders. Psychological distress and
musculoskeletal disorders were significantly greater in workers with Job Strain
and Iso Strain. After taking non-occupational factors into account, some
occupational factors were found to increase the risk of psychological distress
(Likert >12): imposed full-time schedule, being unable to simultaneously
meet both quality and quantity requirements, situations of tension with
clients, negative comments from superiors, and lack of recognition from
superiors. Conclusions: This survey of over 2,000 call center employees
highlighted the high frequency of psychological distress in this population and
the health impact of working conditions. ® Springer-Verlag 2008

Abstract: Asthma affects approximately 22 million adults and children in the
United States and poses a significant economic burden on the health care
system and on employers. According to the National Heart, Lung, and Blood
Institute, direct and indirect costs for all forms of asthma totaled $19.7 billion
in 2007. Prescription drugs represented the largest single direct cost at $6.2
billion. To gather information about asthma burden and any evidentiary
requirements and product attributes that may influence formulary decision
making for an emerging inhaled corticosteroid (ICS) asthma therapy, decision
makers at 10 MCOs and 8 employers with more than 51 million members
were interviewed. MCO decision makers reported that the economic impact of
asthma was most notable in hospitalizations, emergency department visits,
and prescription drugs, followed by physician office visits and medication
adverse events. Employers indicated the impact of asthma on absenteeism,
productivity, presenteeism, and employer health care costs. Efficacy, safety,
cost, and adherence were found to be the primary factors that influence
formulary decision makers when they evaluate emerging ICS asthma
therapies

correction in choir singers. J Acoust Soc Am 2009;126:407-413.
Ref ID: 18
Abstract: Highly and moderately skilled choral singers listened to a perfect
fifth reference, with the instruction to complement the fifth such that a major
triad resulted. The fifth was suddenly and unexpectedly shifted in pitch, and
the singers' task was to shift the fundamental frequency of the sung tone
accordingly. The F0 curves during the transitions often showed two phases, an
initial quick and large change followed by a slower and smaller change,
apparently intended to fine-tune voice F0 to complement the fifth.
Anesthetizing the vocal folds of moderately skilled singers tended to delay the
reaction. The means of the response times varied in the range 197- 259 ms
depending on direction and size of the pitch shifts, as well as on skill and
anesthetization

impact on the call-centre industry. BMC Public Health 2009;9:108.
Ref ID: 370
Abstract: BACKGROUND: Within the last decade there has been a growth in
the call-centre industry in the UK, with a growing awareness of the voice as
an important tool for successful communication. Occupational voice problems
such as occupational dysphonia, in a business which relies on healthy,
effective voice as the primary professional communication tool, may threaten
working ability and occupational health and safety of workers. While previous
studies of telephone call-agents have reported a range of voice symptoms and
functional vocal health problems, there have been no studies investigating the
use and impact of vocal performance in the communication industry within
the UK. This study aims to address a significant gap in the evidence-base of
occupational health and safety research. The objectives of the study are: 1. to
investigate the work context and vocal communication demands for callagents; 2. to evaluate call-agents' vocal health, awareness and performance;
and 3. to identify key risks and training needs for employees and employers
within call-centres. METHODS AND DESIGN: This is an occupational
epidemiological study, which plans to recruit call-centres throughout the UK
and Ireland. Data collection will consist of three components: 1. interviews
with managers from each participating call-centre to assess their
communication and training needs; 2. an online biopsychosocial questionnaire
will be administered to investigate the work environment and vocal demands
of call-agents; and 3. voice acoustic measurements of a random sample of
participants using the Multi-dimensional Voice Program (MDVP). Qualitative
content analysis from the interviews will identify underlying themes and
issues. A multivariate analysis approach will be adopted using Structural
Equation Modelling (SEM), to develop voice measurement models in
determining the construct validity of potential factors contributing to
occupational dysphonia. Quantitative data will be analysed using SPSS version
15. Ethical approval is granted for this study from the School of
Communication, University of Ulster. DISCUSSION: The results from this
study will provide the missing element of voice-based evidence, by appraising
the interactional dimensions of vocal health and communicative performance.
This information will be used to inform training for call-agents and to
contribute to health policies within the workplace, in order to enhance vocal
health

Relationships between self-evaluations of voice and working conditions,
background factors, and phoniatric findings in female teachers. Logoped
Phoniatr Vocol 2009;34:20-31.
Ref ID: 21
Abstract: Self-evaluations of voice, working conditions, and results of
phoniatric examination were studied in 78 female primary school teachers.
Most teachers evaluated their vocal capabilities as 'normal'; nevertheless 1/3
reported two or more weekly symptoms. Unsatisfactory air quality,
background noise, and stressful working conditions were seen as the most
harmful environmental factors. A total of 14% of the subjects had organic
laryngeal changes, 37% had mild changes, and 49% were found to be
healthy. These findings did not correlate with self-evaluation of voice, vocal
symptoms, or voice-related quality of life. Teaching experience or teaching
hours per week did not correlate with laryngeal findings or symptoms. The
results illustrate the complex nature of voice assessment and the need of
assessment tools specially suited for functionally healthy voice professionals

Abstract: Caring for the professional singer, whether an operatic performer or
serious amateur, involves careful consideration of both physical and emotional
components, as it does in other performing artists. However, because the
head and neck contain representatives of other major organ systems in close
proximity to the phonating larynx, singing is additionally vulnerable to a range
of diseases of the respiratory, gastrointestinal, and endocrine systems. This
review provides an overview of the conditions typically encountered in singers
These include occupational disorders (muscle tension dysphonia, vocal
nodules, vocal hemorrhage and polyps, chronic voice deterioration), general
health issues with vocal implications (respiratory diseases, gastric reflux,
endocrine problems, medication usage), as well as lifestyle considerations

Abstract: The COST Action 2103 "Advanced Voice Function Assessment" is a
joint initiative of speech processing teams (engineers and physicists) and the
European Laryngological Research Group (ELRG) (laryngologists
/phoniatricians). The Action officially started in December 2006, and is
running till the end of 2010. 17 European countries are involved. A main
objective is a better understanding of the relationship between biomechanical
changes at the level of the vocal folds - as induced by pathology and tissue
reaction to strain - and alterations of the acoustical voice signal. This needs to
result in developing accurate, objective and clinically useful methods of
investigation of voice quality in patients, and of strategies for preventing
occupational voice disorders in professional speakers. Modelling is an
essential tool in this process. ® 2009 Elsevier Ltd. All rights reserved

Ref ID: 14
Abstract: BACKGROUND: The aim of this study was to assess the application
of Voice Handicap Index (VHI) in the diagnosis of occupational voice disorders
in teachers as compared with the dysphonic non-teachers population.
MATERIALS AND METHODS: The subjective assessment of voice by VHI was
performed in 105 teachers with dysphonia and 60 dysphonic subjects whose
jobs did not involve vocal effort. The control group comprised 65 healthy
individuals with normal voice. RESULTS: The results of total VHI score and
each of its subscales, functional, emotional and physical, were significantly
worse in the study groups (I and II) than in the control group (p < 0.001).
The analysis of VHI-score distribution showed that the highest percentage of
subjects in groups I and II self-assessed their own voice problems as
moderate disability (67% and 57%), while 20% of teachers and 16% of nonteachers reported severe voice disability. All individuals in the control group
assessed their voice problems as minor, their results fell within the range of
the lowest level of VHI score. CONCLUSIONS: This study confirmed that VHI
as a tool for self-assessment of voice can significantly contribute to the
diagnosis of occupational and non-occupational dysphonia

mental health in teachers: a cross-sectional nationwide study. BMC Public

Ref ID: 15
Abstract: BACKGROUND: Teachers, as professional voice users, are at
particular risk of voice disorders. Among contributing factors, stress and
psychological tension could play a role but epidemiological data on this
problem are scarce. The aim of this study was to evaluate prevalence and
cofactors of voice disorders among teachers in the French National Education
system, with particular attention paid to the association between voice
complaint and psychological status. METHODS: The source data come from an
epidemiological postal survey on physical and mental health conducted in a
sample of 20,099 adults (in activity or retired) selected at random from the
health plan records of the national education system. Overall response rate
was 53%. Of the 10,288 respondents, 3,940 were teachers in activity
currently giving classes to students. In the sample of those with complete
data (n = 3,646), variables associated with voice disorders were investigated
using logistic regression models. Studied variables referred to demographic
characteristics, socio-professional environment, psychological distress, mental
health disorders (DSM-IV), and sick leave. RESULTS: One in two female
teachers reported voice disorders (50.0%) compared to one in four males
(26.0%). Those who reported voice disorders presented higher level of
psychological distress. Sex- and age-adjusted odds ratios [95% confidence
interval] were respectively 1.8 [1.5-2.2] for major depressive episode, 1.7
[1.3-2.2] for general anxiety disorder, and 1.6 [1.2-2.2] for phobia. A
significant association between voice disorders and sick leave was also
demonstrated (1.5 [1.3-1.7]). CONCLUSION: Voice disorders were frequent
among French teachers. Associations with psychiatric disorders suggest that a
situation may exist which is more complex than simple mechanical failure.
Further longitudinal research is needed to clarify the comorbidity between
voice and psychological disorders

Ref ID: 35
Abstract: Muscle tension dysphonia (MTD) is a hyperfunctional voice disorder
commonly seen in professional voice users. To date, published acoustic
studies of this disorder have mainly focused on nontonal language speakers,
and no publication has documented its impact on lexical tone characteristics.
In this study, we examined whether and how this voice disorder affected
acoustically and perceptually the characteristics of tones in Vietnamese
teachers. Voice data were obtained from 42 Vietnamese female primary
school teachers diagnosed with MTD and 30 vocally healthy teachers. Tonal
data were analyzed using Computerized Speech Lab (CSL-4300B) and Speech
Analyzer. Parameters analyzed included the two most important acoustic cues
in Vietnamese tones, that is, tonal fundamental frequency (F(0)) and
laryngealization. Tonal F(0) was assessed using a factorial analysis of variance
with group and career durations as independent variables. Tonal samples
were also perceptually assessed by a panel of native speakers of the same
dialect. The results showed that MTD lowered tonal F(0) in high tones and
tones with extensive fundamental frequency variation. There was also a
significant main effect for career duration; in MTD group, tonal F(0) was lower
in teachers with longer career duration. The teachers with MTD showed
different patterns of laryngealization compared with the control group. Tone
perception was poorer for tones with extensive fundamental frequency
variation and without a typical phonation type. The results in this group of
teachers supported our hypothesis that MTD impairs lexical tone phonation

Abstract: There has been no published research on muscle tension dysphonia
(MTD) in speakers who use a tonal language. Using a sample of 47 Northern
Vietnamese female primary school teachers with MTD, we aimed to discover
whether professional voice users of tonal languages presented with the same
symptoms of MTD as speakers of nontonal languages and whether they
presented with additional symptoms as a result of speaking a tonal language.
The vocal characteristics were assessed by use of a questionnaire and expert
perceptual evaluation. Laryngeal features were assessed by
photolaryngoscopy. The results showed that MTD was associated with a larger
number of vocal symptoms than previously reported. However, the
participants did not have the same vocal symptoms reported in English
speakers, for example, hard glottal attack, pitch breaks, unusual speech rate,
and glottal fry. Factor analysis of the vocal symptoms revealed three factors:
"vocal fatigue/hyperfunction," "physical discomfort," and "voice quality," all of
which demonstrated high reliability. The major laryngeal characteristic was a
glottal gap. The glottal shapes observed included: 44.7% had an incomplete
closure, 29.8% a posterior gap, 12.8% an hourglass-shaped gap, 8.5% a
spindle-shaped gap, and 4.3% had complete glottal closure. The findings
implied a potential contribution of linguistic-specific factors and teachingrelated factors to the presentation of this voice disorder in this group of
teachers

Abstract: OBJECTIVE: This study evaluated the treatment effects of vocal
function exercises on muscle tension dysphonia (MTD) in tonal language
speakers. DESIGN: Single-blinded, randomized, controlled, clinical trial.
METHODS: Forty female primary school teachers from Northern Vietnam,
diagnosed with MTD, were randomly allocated into a treatment group (n =
22), which used a full vocal exercise protocol (FE) (modified for use with
Vietnamese speakers), and a control group (n = 18) which was treated with a
partial vocal exercise protocol (PE). The treatment duration was 4 weeks for
both groups. MAIN OUTCOME MEASURES: Acoustic and perceptual data were
used as primary outcome measures. Acoustic parameters included frequency
and amplitude perturbation, harmonics-to-noise ratio (HNR), mean
fundamental frequency of the broken and rising tones, and parameters
representing pitch movement in the rising tone. Perceptual analyses were
performed on pre- and posttreatment samples of the sustained /a/ sound
using anchor vocal samples. Self-report data, collected via a posttreatment
questionnaire, comprised the secondary outcome measure. RESULTS:
Significant changes in perturbation, HNR, and perceptual data were observed
in the FE group but not in the PE group. The FE group showed increased size
and speed of pitch change. Participants from both groups showed positive
changes in some tonal parameters after treatment. However, the magnitude
of change and the number of participants with positive changes were larger in
the FE group. CONCLUSION: The data showed that vocal function exercises
may be a cost-effective treatment for MTD

target implementation in vietnamese female teachers. J Voice 2009;23:690698.
Ref ID: 32
Abstract: Muscle tension dysphonia (MTD) is a voice disorder with
deteriorated vocal quality, particularly pitch problems. Because pitch is mainly
controlled by the laryngeal muscles, and because MTD is characterized by
increased laryngeal muscle tension, we hypothesized that it may result in
problems in pitch target implementation in tonal languages. We examined
tonal samples of 42 Vietnamese female primary school teachers diagnosed
with MTD and compared them with 30 vocally healthy female teachers who
spoke the same dialect. Tonal data were analyzed using Computerized Speech
Lab (CSL-4300B) for Windows. From tonal sampling bases, fundamental
frequency (F0) was measured at target points specified by contour
examination. Parameters representing pitch movement including time, size,
and speed of movement were measured for the falling tone and rising tone.
We found that F0 at target points in MTD group was lowered in most tones,
especially tones with extensive F0 variation. In MTD group, target F0 of the
broken tone in isolation was 37.5 Hz lower (P<0.01) and target F0 of rising
tone in isolation was 46 Hz lower (P<0.01) than in control group. In MTD
group, speed of pitch fall of the falling tone in isolation was faster than control
group by 2.2 semitones/second (st/s) (P<0.05) and speed of pitch rise in
the rising tone in isolation was slower than control group by 7.2 st/s
(P<0.01). These results demonstrate that MTD is associated with problems
in tonal pitch variation

questionnaire 'Benefits Obtained with Voice Training' (BVT). The vocal training
program was not considered effective with regard to the occurrence of vocal
symptoms. However, due to a probable increase in symptoms in untrained
telemarketers, it can work as a protective factor. According to BVT answers,
the vocal training contributed to an improvement in vocal use as a
communication tool for telemarketers

Ref ID: 458
Abstract: BACKGROUND: Children with motor impairments often have the
motor speech disorder dysarthria, a condition which effects the tone, power
and coordination of any or all of the muscles used for speech. Resulting
speech difficulties can range from mild, with slightly slurred articulation and
low-pitched voice, to profound, with an inability to produce any recognisable
words. Children with dysarthria are often prescribed communication aids to
supplement their natural forms of communication. However, there is variation
in practice regarding the provision of therapy focusing on voice and speech
production. Descriptive studies have suggested that therapy may improve
speech, but its effectiveness has not been evaluated. OBJECTIVES: To assess
whether direct intervention aimed at improving the speech of children with
dysarthria is more effective than no intervention at all. To assess whether
individual types of intervention are more effective than others in improving
the speech intelligibility of children with dysarthria. SEARCH STRATEGY: We
searched CENTRAL, MEDLINE, EMBASE, CINAHL , LLBA, ERIC, PsychInfo, Web
of Science, Scopus, UK National Research Register and Dissertation Abstracts
up to April 2009, handsearched relevant journals published between 1980 and
April 2009, and searched proceedings of relevant conferences between 19962009. SELECTION CRITERIA: We considered randomised controlled trials and
studies using quasi-experimental designs in which children were allocated to
groups using non-random methods. DATA COLLECTION AND ANALYSIS: L
Pennington conducted searches of all databases and conference reports. L
Pennington, N Miller and S Robson handsearched journals. All searches
included a reliability check in which a second review author independently
checked a random sample comprising 15% of all identified reports. We
planned that two review authors would independently assess the quality and
extract data from eligible studies. MAIN RESULTS: No randomised controlled
trials or group studies were identified. AUTHORS' CONCLUSIONS: We found
no firm evidence of the effectiveness of speech and language therapy to
improve the speech of children with early acquired dysarthria. No change in
practice is warranted at the present time. Rigorous research is needed to
investigate if the positive changes in children's speech observed in small
descriptive studies are shown in randomised controlled trials. Research should
examine change in children's speech production and intelligibility. It should
also investigate the secondary education, health and social care outcomes of
intervention, including children's interaction with family, friends and teachers,
their participation in social and educational activities, and their quality of life.
Cost and acceptability of interventions must also be investigated. SPEECH
THERAPY FOR CHILDREN WITH EARLY ACQUIRED DYSARTHRIA: Dysarthria is
a disorder which reduces the control of movements for speech. Children with
dysarthria often have shallow, irregular breathing and speak on small,
residual pockets of air. They have low pitched, harsh voices, nasalised speech
and very poor articulation. Together, these difficulties make the children's
speech difficult to understand. Dysarthria is caused by neurological
impairment and can arise early in children's lives, from neurological damage
sustained before, during or after birth, such as in cerebral palsy, or in early
childhood through traumatic brain injury or neurological disease.
Communication difficulties have a profound impact on children's development.
They reduce the quality of life of children with cerebral palsy and place
children at risk of social exclusion, educational failure and later
unemployment. Speech and language therapy aims to help children to control
the movements for breathing and speech and so become more intelligible.
Small, observational studies have suggested that for some children therapy
might have been associated with positive changes in intelligibility and clarity
of children's voices. This review aimed to investigate if therapy is generally
effective for children with dysarthria acquired early in life, and if certain types
of therapy may be better than others. We found no randomised controlled
trials or controlled group studies which investigate the effects of speech and
language therapy to improve the speech of children with dysarthria acquired
below three years of age. Rigorous research, using randomised controlled
trials, is needed to evaluate if therapy can help children to increase the
intelligibility of their speech and if enhanced intelligibility increases children's
participation in social and educational activities and their quality of life

Ref ID: 23
Abstract: This investigation compares vocal tract dimensions and the
classification of singer voices by examining an x-ray material assembled
between 1959 and 1991 of students admitted to the solo singing education at
the University of Music, Dresden, Germany. A total of 132 images were
available to analysis. Different classifications' values of the lengths of the total
vocal tract, the pharynx, and mouth cavities as well as of the relative position
of the larynx, the height of the palatal arch, and the estimated vocal fold
length were analyzed statistically, and some significant differences were
found. The length of the pharynx cavity seemed particularly influential on the
total vocal tract length, which varied systematically with classification. Also
studied were the relationships between voice classification and the body
height and weight and the body mass index. The data support the hypothesis
that there are consistent morphological vocal tract differences between
singers of different voice classifications

Ref ID: 39
Abstract: Students admitted to the solo singing education at the University of
Music Dresden, Germany have been submitted to a detailed physical
examination of a variety of factors with relevance to voice function since
1959. In the years 1959-1991, this scheme of examinations included X-ray
profiles of the singers' vocal tracts. This material of 132 X-rays of voice
professionals was used to investigate different laryngeal morphological
measures and their relation to vocal fold length. Further, the study aimed to
investigate if there are consistent anatomical differences between singers of
different voice classifications. The study design used was a retrospective
analysis. Vocal fold length could be measured in 29 of these singer subjects
directly. These data showed a strong correlation with the anterior-posterior
diameter of the subglottis and the trachea as well as with the distance from
the anterior contour of the thyroid cartilage to the anterior contour of the
spine. These relations were used in an attempt to predict the 132 singers'
vocal fold lengths. The results revealed a clear covariation between predicted
vocal fold length and voice classification. Anterior-posterior subglottic-tracheal
diameter yielded mean vocal fold lengths of 14.9, 16.0, 16.6, 18.4, 19.5, and
20.9mm for sopranos, mezzo-sopranos, altos, tenors, baritones, and basses,
respectively. The data support the assumption that there are consistent
anatomical laryngeal differences between singers of different voice
classifications, which are of relevance to pitch range and timbre of the voice

diseases caused by metalworking fluids. Curr Opin Allergy Clin Immunol
2009;9:97-102.
Ref ID: 400
Abstract: Both asthma and hypersensitivity pneumonitis occur among workers
exposed to metalworking fluid. The incidence of these diseases among such
workers is unknown. Outbreaks of these conditions continue to be identified
among metal machinists. Whether these are true outbreaks associated with
some breakdown in workplace controls or, rather the recognition of ongoing
endemic disease that is typically misdiagnosed as pneumonia or common
adult onset asthma, needs further evaluation. Further work to elucidate the
specific causal agent(s) is necessary to affect effective workplace controls.
Treating an identified individual case as an index case with a followup
workplace investigation will only be possible if practicing physicians interact
with public health authorities to report newly diagnosed cases

vocal cord dysfunction and occupational bronchial asthma: differential
diagnosis in a health care worker. Int J Occup Med Environ Health
2009;22:401-406.
Ref ID: 13
Abstract: OBJECTIVES: Vocal cord dysfunction (VCD) is an uncommon
respiratory disease characterized by the paradoxical adduction of vocal cords
during inspiration, that may mimic bronchial asthma. The pathogenesis of
VCD has not been clearly defined but it is possible to recognize nonpsychologic and psychologic causes. The majority of patients are female but,
interestingly, a high incidence of VCD has been documented in health care
workers. A misdiagnosis with asthma leads to hospitalisation, unnecessary
use of systemic steroids with related adverse effects, and sometimes
tracheostomy and intubation. In a subset of VCD patients, the disease can be
attributed to occupational or environmental exposure to inhaled irritants.
MATERIALS AND METHODS: We report the case of a 45-year-old woman,
working as a nurse, who complained of wheezing, cough, dyspnoea related to
inhalation of irritating agents (isopropylic alcohol, formaldehyde, peracetic
acid). She underwent chest radiography, pulmonary function assessment both
in the presence and in the absence of symptoms, bronchial provocation with
methacholine and bronchodilation test with salbutamol to recognize asthma's
features, allergy evaluation by skin prick tests and patch tests and videolaryngoscopy. RESULTS: VCD diagnosis was made on the basis of videolaryngoscopy, that visualized the paradoxical motion of the vocal cords during
symptoms, in the absence of other pathologic processes. CONCLUSIONS: This
case fulfils the proposed criteria for the diagnosis of irritant VCD (IVCD). This
is the first report of VCD onset following exposure to several irritants:
formaldehyde, glutaraldehyde, sopropylic alcohol, peracetic acid-hydrogen
peroxide mixture. These substances are used as cleaning and antiseptic
agents in healthcare settings and some ones can also be found in many
indoor environments. A correct diagnosis is important both to give the
appropriate treatment and for medical legal implications

the Voice Handicap Index (VHI). This study focuses on the relation between
voice handicap and smoking in dysphonic patients, who are using voice
professionally. Thirty outpatient (25 female and 5 male, aged 40 to 55 years)
voice department attendees suffering from professional dysphonia took part
in this study. All patients after phoniatric examination completed the Polish
version of the Voice Handicap Index (VHI). The questions concern functional,
emotional and physical complains due to dysphonia. Most of smokers did not
complain of dysphonia related problems comparing to non smokers. Even the
scores of functional and emotional scales of VHI in smokers shown better
results (less handicap) than in nonsmokers. Smoking does not affect patients

Ref ID: 478
Abstract: Skin diseases are the second most common work-related health
problem in Europe. They represent more than 7% of all occupational illnesses
and are one of the most important emerging risks related to the exposure to
chemical, physical and biological risk factors. The fact that there is no
scientific method to measure the level of the body's exposures to risks via
dermal contact and their physiological consequences, increases the
importance of recognising risk factors and developing methods of assessing
the level of exposure and controlling it. This report presents an overview of
dermal exposures and occupational skin diseases. It also presents the
principal policies relating to the recognition and recording of skin diseases, as
well as the recognition, assessment and control of dermal exposure to
chemical, biological and physical risk factors in the Member States of the

methods for safety and quality of service analysis of systems connected via a
communication network. 2008.
Ref ID: 480
Abstract: Although telemedicine was developed in the 1960s, it is only in
recent years that its full application has become possible with the
improvement of communication networks and the introduction of mobile
terminals. The most successful applications have been developed in the fields
of cardiology (with the trans-telephonic electrocardiograph), infectious
disease assistance (for remote monitoring of individual patients as well as for
the prompt notification of infectious and communicable diseases), and of
teleconsultancy of experts. Telemedicine is especially required when it is
difficult to provide local health services (e.g., on ships, aircrafts, in case of
major regional crises). Currently, many telemedicine applications are based
on public mobile networks (PMNs). In these cases, the dependability of
services based on PMN connections (such as voice and data connections) is
required to avoid that adverse events (such as failure of PMN main elements
or PMN resource contention) may affect the delivery of health services.
Objectives: Major regional crises (e.g., great floods and earthquakes) may
require telemedical assistance based on PMNs. In telemedical and civil
protection applications, telemedical assistance systems (TASs) based on PMNs
are proposed as prototype systems for the diagnosis and medical treatment of
victims of catastrophic events. This paper analyses the reliability of a PMN
supporting Global System for Mobile communications (GSM) and General
Packet Radio Service (GPRS) connections for exchanging voice and data
communications between remote mobile nodes and a telemedical assistance
centre (TMAC). Methods: The dependability measures of PMN connections
were assessed by building, computing and analyzing stochastic models of the
network. Results: In particular, a GPRS model based on the Stochastic Activity
Network formalism was analysed. Two different modelling levels were
adopted. At the first level, two separate submodels were built in order to
calculate, respectively, the pure unavailability and the pure performance of
the packet data connection. At the second level, the submodels were joined
for computing the dependability measures of the GPRS connection.
Information and communication technologies can be factors of progress even
in the healthcare sector. Some experiences have shown that the additional
costs required by telemedicine systems are widely offset by savings in terms
of time and human resources. Thus, telemedicine can significantly contribute
to rationalize medical health interventions, while simultaneously aiming for
cost-effectiveness in public health

Ref ID: 31
Abstract: This study aimed to identify risk factors for voice disorders
(hoarseness in the previous six months as an initial manifestation, and vocal
cord nodules as a more severe manifestation of overt disease) among
teachers. The cross-sectional study included 747 women teachers from
elementary and middle schools in the public school system in Vitoria da
Conquista, Bahia State, Brazil. Data were collected using a self-applied,
standardized questionnaire. Hoarseness in the previous six months was
reported by 59.2% of teachers and vocal cord nodules by 12.9%. Logistic
regression techniques showed that hoarseness was statistically associated
with > 24 classroom hours per week, work in more than one school, and
having to make an effort to speak. Vocal cord nodules were associated with
working > 5 years as a teacher, work in more than one school, working at
another job besides teaching, and having to make an effort to speak. In
conclusion, voice disorders are frequent among schoolteachers and are
associated with multiple occupational risk factors, besides purely biological
ones

Abstract: Background: The voice of choir conductors. Aim: To evaluate the
vocal quality of choir conductors based onthe production of a sustained vowel
during singing and when speaking in order to observe auditory and acoustic
differences. Method: Participants of this study were 100 choir conductors,
with an equal distribution between genders. Participants were asked to
produce the sustained vowel "q" using a singing and speaking voice. Speech
samples were analyzed based on auditory-perceptive and acoustic
parameters. The auditory-perceptive analysis was carried out by two speechlanguage pathologist, specialists in this field of knowledge. The acoustic
analysis was carried out with the support of the computer software Doctor
Speech (Tiger Electronics, SRD, USA, version 4.0), using the Real Analysis
module. Results: The auditory-perceptive analysis of the vocal quality
indicated that most conductors have adapted voices, presenting more
alterations in their speaking voice. The acoustic analysis indicated different
values between genders and between the different production modalities. The
fundamental frequency was higher in the singing voice, as well as the values
for the first formant; the second formant presented lower values in the
singing voice, with statistically significant results only for women. Conclusion:
The voice of choir conductors is adapted, presenting fewer deviations in the
singing voice when compared to the speaking voice. Productions differ based
the voice modality, singing or speaking

third reactions to stage fright involve (a) increased and (b) decreased muscle
tonus and their associated breathing patterns. Furthermore, I shall indicate
how singers manage to pull themselves together through the very act of

Ref ID: 438
Abstract: OBJECTIVE: To compare the usefulness for training of a porcine
model (larynx, trachea, and pig skin) and a manikin model using a Portex
cricothyrotomy kit (PCK). METHODS: In a prospective randomised crossover
trial, participants in the airway workshop performed crico-thyrotomy using a
PCK on the porcine and manikin models (Tracheostomy Trainer and Case).
The porcine model was made with larynxes and trachea from freshly
slaughtered pigs and covered with a piece of thinned pigskin stapled to a
wooden board. Participants were asked to assess the following: reality of skin
turgor; difficulty with skin penetration, landmark recognition and procedure;
reality of the model; and preference for each model using a visual analogue
scale (VAS) of 0-10 cm. The VAS scores for each model were compared.
RESULTS: 49 participants were included in the study. Mean (SD) VAS scores
for the reality of skin turgor, degree of difficulty with skin penetration and
landmark recognition were higher with the porcine model than with the
manikin model (7.0 (2.1) vs 4.7 (2.0), 6.4 (2.4) vs 3.6 (2.2), 5.1 (2.2) vs 4.2
(2.5), respectively). There was no difference between the models in the
difficulty of the procedure (5.0 (2.4) vs 4.7 (3.2)). The porcine model had a
higher VAS score for overall reality and preference of the model (7.1 (2.0) vs
4.8 (2.3) and 7.1 (2.0) vs 4.8 (2.2), respectively). CONCLUSION: The porcine
model is a more useful training tool than the manikin model for
cricothyrotomy with PCK because of its reality and similarity to human
anatomy

Vocal cord dysfunction in former World Trade Center (WTC) rescue and
recovery workers and volunteers. Am J Ind Med 2008;51:161-165.
Ref ID: 43
Abstract: BACKGROUND: Vocal cord dysfunction (VCD) is a condition
characterized by paradoxical partial adduction of the vocal cords on
inspiration. It has been associated with exposures to irritants, as well as with
psychological illnesses and conditions. Workers who participated in the
recovery of the WTC disaster site were exposed to a large amount of irritants
as well as considerable psychological stressors. We describe the clinical
characteristics of 10 symptomatic former WTC workers diagnosed with this
condition, as well as the frequency of spirometric findings suggestive of
variable extrathoracic obstruction. METHODS: Workers who became
symptomatic after their WTC work experience have been evaluated clinically
by a multidisciplinary team at an academic medical center. The evaluation
included history, physical examination, chest radiograph, blood tests, and preand post-bronchodilator spirometry in all patients. Additional evaluations and
diagnostic tests included otolaryngological evaluation with flexible
rhinolaryngoscopy and stroboscopy, gastroenterological and psychiatric
evaluations. A randomly selected sample of 172 spirometry results were
reviewed for evidence of inspiratory flow limitation. RESULTS: Variable
extrathoracic obstruction was found in 18.6% of the spirometries. Ten
patients were diagnosed with VCD. In addition to symptoms suggestive of comorbid conditions (particularly rhinitis and acid reflux disease), most of the
10 patients had (1) hoarseness, (2) dyspnea that was not associated with
bronchial hyperreactivity, or (3) dyspnea associated with asthma, with either
mild bronchial hyperreactivity and/or poor response to asthma treatment.
CONCLUSIONS: VCD appears to be part of the spectrum of airway disorders
caused by occupational exposures at the WTC disaster site. Further study of
this association is warranted

Ref ID: 48
Abstract: The objective of this study is to establish the prevalence of
dysphonia and associated factors in public school female teachers working in
Belo Horizonte. This cross-sectional study was conducted on a random sample
of schools between May 2004 and July 2005. There were 2103 elementary
education daytime teachers from 83 schools included in the study. Selfapplied questionnaires were used for data collection. These included questions
on social and demographic matters, general health and mental health
(General Health Questionnaire-12 [GHQ-12]), the environment and
organization of work, and voice-related aspects. The variable dysphonia was
classified as absent, possible, or probable based on the association between
frequency of fatigue when speaking and worsened voice quality during the
past 15 days. Multinomial logistic regression was used to analyze factors
independently associated with dysphonia in each response subgroup and in
total. One third of the female teachers did not report voice symptoms during
the past 15 days (33%). The prevalence of probable dysphonia was 15%, and
the prevalence for possible dysphonia was 52%. Factors associated with
probable dysphonia were presence of recent upper airway problems (odds
ratio [OR]=5.95, 95% confidence interval [CI]=4.06-8.71), problems at work
because of voice (OR=65.30, 95% CI=19.33-220.59), other activities with
intense voice use (OR=1.71, 95% CI=1.08-2.71), high noise levels
(OR=2.55, 95% CI=1.72-3.76), poor ventilation in the classroom (OR=2.00,
95% CI=1.24-3.22), current mental disorder (OR=3.20, 95% CI=2.18-4.70),
sedentary life style (OR=1.94, 95% CI=1.21-3.09), and marriage (OR=1.70,
95% CI=1.16-2.47). Associations between probable dysphonia, poor working
conditions, health-related aspects, and professional jeopardy indicate the
complexity of dysphonia in female teachers and the need for collective
intervention strategies

Abstract: Chronic obstructive pulmonary disease (COPD) is a major
respiratory illness in Canada that is preventable and treatable but
unfortunately remains underdiagnosed. The purpose of the present article
from the Canadian Thoracic Society is to provide up-to-date information so
that patients with this condition receive optimal care that is firmly based on
scientific evidence. Important summary messages for clinicians are derived
from the more detailed Update publication and are highlighted throughout the
document. Three key messages contained in the update are: use targeted
screening spirometry to establish a diagnosis and initiate prompt
management (including smoking cessation) of mild COPD; improve dyspnea
and activity limitation in stable COPD using new evidence-based treatment
algorithms; and understand the importance of preventing and managing
acute exacerbations, particularly in moderate to severe disease. ® 2008

Ref ID: 30
Abstract: Changes of vocal tract shape accompanying changes of vocal
register and pitch in singing have remained an unclear field. Dynamic realtime magnetic resonance imaging (MRI) was applied to two professional
classical singers (a tenor and a baritone) in this pilot study. The singers sang
ascending scales from B3 to G#4 on the vowel /a/, keeping the modal
register throughout or shifting to falsetto register for the highest pitches. The
results show that these singers made few and minor modifications of vocal
tract shape when they changed from modal to falsetto and some clear
modifications when they kept the register. In this case the baritone increased
his tongue dorsum height, widened his jaw opening, and decreased his jaw
protrusion, while the tenor merely lifted his uvula. The method used seems
promising and should be applied to a greater number of singer subjects in the
future

Video-assisted instruction improves the success rate for tracheal intubation by
novices. British journal of anaesthesia 2008;101:568-572.
Ref ID: 447
Abstract: BACKGROUND: Tracheal intubation via laryngoscopy is a
fundamental skill, particularly for anaesthesiologists. However, teaching this
skill is difficult since direct laryngoscopy allows only one individual to view the
larynx during the procedure. The purpose of this study was to determine if
video-assisted laryngoscopy improves the effectiveness of tracheal intubation
training. METHODS: In this prospective, randomized, crossover study, 37
novices with less than six prior intubation attempts were randomized into two
groups, video-assisted followed by traditional instruction (Group V/T) and
traditional instruction followed by video-assisted instruction (Group T/V).
Novices performed intubations on three patients, switched groups, and
performed three more intubations. All trainees received feedback during the
procedure from an attending anaesthesiologist based on standard cues.
Additionally, during the video-assisted part of the study, the supervising
anaesthesiologist incorporated feedback based on the video images obtained
from the fibreoptic camera located in the laryngoscope. RESULTS: During
video-assisted instruction, novices were successful at 69% of their intubation
attempts whereas those trained during the non-video-assisted portion were
29
successful in 55% of their attempts (P=0.04). Oesophageal intubations
occurred in 3% of video-assisted intubation attempts and in 17% of
traditional attempts (P<0.01). CONCLUSIONS: The improved rate of
successful intubation and the decreased rate of oesophageal intubation
support the use of video laryngoscopy for tracheal intubation training

lecture (VHL) in 60 randomly assigned female teachers. All 60 attended the
lecture, and 30 completed a short training course in addition. Text reading
was recorded in working environments and analyzed for fundamental
frequency (F0), equivalent sound level (Leq), alpha ratio, jitter, shimmer, and
perceptual quality. Self-reports of vocal well-being were registered. In the
VHL group, increased F0 and difficulty of phonation and in the VT group
decreased perturbation, increased alpha ratio, easier phonation, and
improved perceptual and self-reported voice quality were found. Both groups
equally self-reported increase of voice care knowledge. Results seem to
indicate improved vocal well-being after training

Ref ID: 25
Abstract: Voice disorders constitute a serious health problem for teachers.
More than 80% of them experience voice disorders and still among those
40% suffer from pathological phoniatric changes confirmed by phoniatric
examination. Chronic disorders resulting from vocal abuse and misuse are the
most frequent among occupational diseases diagnosed in Poland. THE AIM OF
THE STUDY: To investigate the chronic voice disorders among the teaching
community of Medical University of Bialystok and to examine its awareness of
voice hygiene and proper vocal techniques. MATERIAL AND METHOD: The
research was based on a survey of 434 university teachers from Medical
University of Bialystok. Results. Increased voice fatigue and voice loss were
most often the consequence of prolonged voice use (over 20 years).
Occupational voice disorders were more frequent in females, even though
they did not ignore initial symptoms and consulted specialists. Disregard for
prevention, reluctance to undergo treatment, and negligence of the first
symptoms of disease are the most common cause of occupational voice
disorders. CONCLUSION: Working in a voice-friendly environment, organizing
trainings devoted to voice hygiene and vocal techniques are in favor of
enhancing the voice function of university teachers

pitch change in professional singers. J Voice 2008;22:622-633.
Ref ID: 45
Abstract: The aim of this study was to examine the physiology of pitch change
in terms of laryngeal and respiratory mechanisms in professional singers.
Nine female professional singers were recruited to participate in the study.
Videoendoscopic recordings of the participants producing one-octave
ascending and descending scales were used as a basis to apply a ratio
measurement of vocal fold length for each note produced on the scale.
Simultaneous respiratory data using Respitrace were also collected.
Questionnaires (Voice Handicap Index and Vocal Questionnaire) were used to
obtain information about psychosocial aspects related to voice use. Two vocal
fold lengthening patterns (static and dynamic) were observed with pitch
change. Participants exhibiting a static pattern of vocal fold lengthening had
fewer years of vocal training, exhibited a more variable use of vital capacity,
and also began the singing task at a higher position in their vital capacity. The
reverse was true for participants exhibiting a dynamic vocal fold pattern.
These preliminary data indicate that the pattern of vocal fold lengthening
exhibited by singers may be related to the number of years of training
possessed. Furthermore, the data indicate that stability in one subsystem
may result in variability in another, as shown by the interaction between the
vocal fold and respiratory patterns

measured by means of laser triangulation. J Voice 2008;22:734-739.
Ref ID: 61
Abstract: A new laser triangulation technique was used to measure vocal fold
length and width in 27 professional opera singers. The singers belonged to
different voice register categories: soprano, mezzo, tenor, and bass/baritone.
High-speed recordings were made during glissandos from each singer's
speaking fundamental frequency (SFF) up to the highest frequency for which
it was possible to place the laser spot on the vocal folds. Vocal fold length and
width were measured at the singers' SFF and then at two or three times the
SFF, and for some singers at four times the SFF. In addition, measurements
were also made at C4 (260 Hz) for all singers. The results confirmed that the
bass/baritone group had significantly longer vocal folds than the soprano
group; also, males have significantly longer vocal folds than females.
Measured values for vocal fold width were significantly larger for the
bass/baritone group compared with all other groups. A measured strain
parameter showed different patterns of vocal fold elasticity with increasing
pitch. The results suggest that although vocal fold length and width contribute
to a singer's voice register category, there seem to be also other parameters
that are essential for this distinction

self-reports of vocal fatigue by female teachers. J Voice 2008;22:283-289.
Ref ID: 66
Abstract: This study investigated the relation of symptoms of vocal fatigue to
acoustic variables reflecting type of voice production and the effects of vocal
loading. Seventy-nine female primary school teachers volunteered as
subjects. Before and after a working day, (1) a 1-minute text reading sample
was recorded at habitual loudness and loudly (as in large classroom), (2) a
prolonged phonation on [a:] was recorded at habitual speaking pitch and
loudness, and (3) a questionnaire about voice quality, ease, or difficulty of
phonation and tiredness of throat was completed. The samples were analyzed
for average fundamental frequency (F0), sound pressure level (SPL), and
phonation type reflecting alpha ratio (SPL [1-5 kHz]-SPL [50 Hz-1 kHz]). The
vowel samples were additionally analyzed for perturbation (jitter and
shimmer). After a working day, F0, SPL, and alpha ratio were higher, jitter
31
and shimmer values were lower, and more tiredness of throat was reported.
The average levels of the acoustic parameters did not correlate with the
symptoms. Increase in jitter and mean F0 in loud reading correlated with
tiredness of throat. The results seem to suggest that, at least among
experienced vocal professionals, voice production type had little relevance
from the point of view of vocal fatigue reported. Differences in the acoustic
parameters after a vocally loading working day mainly seem to reflect
increased muscle activity as a consequence of vocal loading

laryngeal function during spontaneous speaking in teachers with voice
disorders. J Speech Lang Hear Res 2008;51:333-349.
Ref ID: 40
Abstract: PURPOSE: To determine if respiratory and laryngeal function during
spontaneous speaking were different for teachers with voice disorders
compared with teachers without voice problems. METHOD: Eighteen teachers,
9 with and 9 without voice disorders, were included in this study. Respiratory
function was measured with magnetometry, and laryngeal function was
measured with electroglottography during 3 spontaneous speaking tasks: a
simulated teaching task at a typical loudness level, a simulated teaching task
at an increased loudness level, and a conversational speaking task.
Electroglottography measures were also obtained for 3 structured speaking
tasks: a paragraph reading task, a sustained vowel, and a maximum
phonation time vowel. RESULTS: Teachers with voice disorders started and
ended their breath groups at significantly smaller lung volumes than teachers
without voice problems during teaching-related speaking tasks; however,
there were no between-group differences in laryngeal measures. Task-related
differences were found on several respiratory measures and on one laryngeal
measure. CONCLUSIONS: These findings suggest that teachers with voice
disorders used different speech breathing strategies than teachers without
voice problems. Implications for clinical management of teachers with voice
disorders are discussed

for educational policy and practice. Public Health 2008;122:691-699.
Ref ID: 385
Abstract: Objectives: To quantify the relative contributions of behavioural,
environmental and psychological factors to the vocal health of teachers, and
to describe the relationships using structural equation modelling, with a view
to identifying preventive action. Method: A cross-sectional survey of teachers
across 69 primary and secondary schools was conducted. In total, 217
responses were analysed. Teachers self-reported on: the quality of their
voice; the frequency with which they perform a series of voice-related
behaviours; the quality of the environment in which they work; the feelings
they have about their vocal health; and an anxiety rating measured by the
State-Trait Anxiety Inventory (STAI) questionnaire. A structural equation
modelling approach was used to estimate the associated effects. Results: The
hypothesized model described the data well. It emerged that voice-related
behaviours, the teachers' work environment and the presence of trait anxiety
had a significant influence on vocal health. Moreover, the model demonstrated
that the quality of the voice is related strongly to how respondents feel about
the condition of their voice, which, in turn, had an indirect reciprocal effect on
the quality of teachers' vocal health. Conclusion: The model demonstrates the
important contributions of psychological and behavioural variables to vocal
health. Of the six independent variables that impact directly on 'vocal
dysfunction', three were found to be statistically significant. These were the
voice-related 'behaviours' that teachers perform, the environment in which
teachers work, and 'trait anxiety present' as measured by the STAI. The
implications of the results are considered in relation to rethinking policy and
practice with the intention of identifying preventative actions to improve the
vocal health of professional educators. ® 2007 The Royal Institute of Public

Abstract: This report describes the work undertaken and the results obtained
during the 3rd project under Health and Safety Executive's Programme for the
Assessment of NDT in Industry (PANI 3). The project was instigated with the
objective of identifying solutions which will allow industry to optimise
performance and minimise the magnitude of operator variation in the
application of manual ultrasonic inspections. The PANI 3 project was managed
on behalf of the Health and Safety Executive by Serco's Inspection Validation
Centre (IVC). In order to keep the report easy to read and assimilate, the
main text gives the key information and the reader is referred to the
Appendices for the supporting detail. The project comprised of an
investigation into the human factors aspects of the manual ultrasonic task and
an assessment of the organisation of NDT and the NDT process (initially
referred to as QA Assessment). Following a data gathering exercise which is
reported in Appendix 2, experimental work was performed with the twin
objectives of investigating the operators' decision making processes and the
correlation of ultrasonic performance with the operators' scores on ability
tests and a number of personality scales. The assessment of the organisation
of NDT was conducted through eliciting information from operators and NDT
vendor companies and reviews of previous reliability studies and other
initiatives to improve NDT reliability

school teachers. Occup Med (Lond) 2008;58:74-76.
Ref ID: 46
Abstract: BACKGROUND: Teachers have been identified as at increased risk of
developing an occupational voice disorder. Primary school teachers are
particularly at risk as they have little opportunity for voice rest during the
working day. AIM: To analyse the prevalence and impact of voice problems in
primary school teachers in the workplace. METHOD: An 85-item questionnaire
was administered to 550 primary school teachers from 42 schools in the
greater Dublin area. RESULTS: A response rate of 55% was obtained. Results
suggest that 27% suffered from a voice problem, 53% an 'intermittent' voice
problem, while only 20% had no voice problem. Teachers of the junior classes
were more vulnerable to developing a voice problem than those of senior
classes. The most common symptoms were 'dry throat' and 'vocal fatigue'.
CONCLUSION: Voice disorders were very common in our study of primary
school teachers. Those most frequently affected taught the younger classes.
Further intervention is needed to identify and minimize risk factors and

reduce the negative impact of voice on the individual and on work

Murphy J. In defense of the stethoscope. Respir Care 2008;53:355-369.
Ref ID: 387
Abstract: The stethoscope is widely considered to be an unreliable instrument.
Many studies document the significant observer variability in its use.
Numerous other diagnostic tools are available that are generally regarded to
provide more reliable diagnostic information. Some even argue that teaching
of the ancient art should be de-emphasized in medical schools. Yet
auscultation with an acoustic stethoscope can provide important, even lifesaving, information. The purpose of this article is to present evidence that
supports the use of the stethoscope in clinical medicine. The argument for the
stethoscope will be made by presenting relevant investigations, including
clinical studies acknowledged to meet the criteria of evidence-based medicine.
It will focus on studies that have employed computerized acoustic technology
to correlate lung sounds with disease states. This technology has advanced in
recent years, which has stimulated a resurgence of interest in auscultation.
Numerous studies have been done that utilized objective methods that
circumvented the problem of observer variability. There is now a good deal of
scientific evidence to support the hypothesis that lung sounds contain
information that is clinically useful. This technology also allows this
information to be collected more efficiently than previously possible. Advances
in educational technology have made it possible to impart information on
auscultation much more easily than was possible in the past. Contrary to
predictions, the stethoscope is not likely to be relegated to the museum shelf
in the near future. Computer technology is making it an even more useful
clinical instrument. ® 2008 Daedalus Enterprises

Ref ID: 22
Abstract: OBJECTIVE: To assess the usefulness of acoustic analysis with vocal
loading test for evaluating the treatment outcomes in occupational voice
disorders. METHODS: Fifty-one female teachers with dysphonia were
examined (Voice Handicap Index--VHI, laryngovideostroboscopy and acoustic
analysis with vocal loading) before and after treatment. The outcomes of
teachers receiving vocal training (group I) were referred to outcomes of group
II receiving only voice hygiene instructions. RESULTS: The results of
subjective assessment (VHI score) and objective evaluation (acoustic
analysis) improved more significantly in group I than in group II. The posttreatment examination revealed a decreased percentage of subjects with
deteriorated jitter parameters after vocal loading, particularly in group I.
CONCLUSIONS: Acoustic analysis with vocal loading test can be a helpful tool
in the diagnosis and evaluation of treatment efficacy in occupational
dysphonia

Abstract: OBJECTIVE: An incorrect voice emission is a risk factor for
developing occupational voice disorders. The study aimed at assessing the
effectiveness of voice therapy in female teachers with dysphonia. METHODS:
The study comprised 133 subjects with voice disorders, taking part in a vocal
training programme. A reference group for the present study included 53
teachers with dysphonia. Questionnaire surveys, phoniatric examination and
videostroboscopic evaluation were conducted at initial and control
examination. RESULTS: In the study group, an improvement after the vocal
training was noted in most of the reported symptoms and also in some
quantitative parameters of phoniatric examinations compared to the findings
for the reference group. The number of patients who assessed their voice as
normal increased significantly after the vocal training (2.3 vs. 46.6%). A
significant increase in the mean maximum phonation time, from 13.3 to 16.6
s, was observed. The same applied to voice frequency range (increase from
171 to 226.8 Hz). CONCLUSIONS: The outcomes of vocal training, such as a
subjective improvement of voice quality and an increase in the quantitative
parameters (prolonged maximum phonation time, extended voice range)
seem to be important parameters for monitoring the effectiveness of training
in correct voice emission

Ref ID: 59
Abstract: The purpose of the present study was to calculate the prevalence
and incidence of voice disorders among teaching staff and find out the
associated occupational risk factors. A case-control study was performed with
905 teachers, 579 cases and 326 controls; 492 were randomly selected and
413 volunteered. All teachers were asked to fill out a standard questionnaire.
Next, a complete laryngeal exam was performed including a general ear,
nose, and throat evaluation and videolaryngostroboscopy. The prevalence of
voice disorders among teaching staff was 57%. The most prevalent lesions
were vocal overstrain (18%), nodular lesions (14%), and hyperfunctional
dysphonia (8%). The incidence rate was 3.87 new cases per year per 1000
teachers. Women had organic lesions three times more than men (odds ratio
[OR]: 3.52, confidence interval [CI]: 2.04-6.09). However, men had chronic
laryngitis three times more than women (OR: 2.93, CI: 1.50-5.71) and
functional dysphonia nearly twice more than women (OR: 1.81, CI: 1.212.69). We find a significant risk of suffering voice disorders in teachers who
smoke daily (OR: 2.31, CI: 1.58-3.37) and who drink several cups of coffee
or tea (OR: 1.87, CI: 1.36-2.56). It is advisable to carry out an annual
evaluation of all teaching staff on account of the high prevalence of voice
disorders among them

Abstract: BACKGROUND: several authors have pointed to the urgent need of
researches and actions involving teachers, in the school environment, that
have a preventive and vocal health promotion character with the purpose of
improving work conditions. AIM: to analyze the vocal complaints, laryngeal
symptoms, vocal habits and vocal profile of teachers of a public school before
and after their participation in voice workshops. METHOD: the study was
divided in different steps: 1st step - closed interview, larynx and perceptiveauditory assessment in which 42 teachers were evaluated; 2nd step - voice
workshops; 3rd step - perceptive-auditory reassessment in which 13 teachers
were evaluated. RESULTS: 73% of the subjects presented vocal complaints;
57.14% presented mild to moderate hoarseness, 78.57% presented
breathiness and 52.38% vocal tension. Evaluation of the larynx indicated that
75.86% of the subjects presented glottal gaps and 34.48% mucous
thickening. After the voice workshops a significant difference was observed in
the level of vocal tension, both in the analysis of the /e/ vowel and in the
analysis of Spontaneous Speech (p = 0.0277 for p > 0.05 for both).
Improvement was observed in vocal care and in the understanding of
intervening and determinant factors for vocal alterations, which are present in
the teaching environment. CONCLUSION: health actions, such as voice
workshops, are important to trigger changes in the work environment as well
as in the health of teachers

Ref ID: 411
Abstract: BACKGROUND: preventive programs have been used with teachers
with the purpose of lowering the number of risk factors for voice disorders.
However, few studies have focused on the effectiveness of these programs.
AIM: to assess changes in behaviors that are considered, according to the
specific literature, as having a negative impact on the voice, during a speech
therapy intervention program offered to educators. METHOD: an experimental
study where a theoretical-practical program involving the professional use of
voice was developed with 26 educators from two day care centers of Spo
Paulo. This program involved five monthly meetings, working up to a total of
twelve hours. During the program, topics concerning negative behaviors that
affect the voice were discussed. On four of the meetings the educators filled
in a protocol, making it possible to analyze the frequency on which they
presented those specific behaviors. Later on, scores were given to the
answers on the protocol in order to compare the findings during the program.
For this comparison the statistical test of Wilcoxon and the linear tendency
chi-square test were used. RESULTS: the gradual decrease in the use of voice
out of work was observed, as well as in speaking with a very low or high pitch
voice and in eating excessively before sleeping. There was an increase in the
occurrence of coughing in the third application of the protocol. As for the
overall monthly averages, statistically significant differences were not found
when comparing the four applications of the protocol. The overall average
score was of 11.75, which was considered moderately abusive. CONCLUSION:
the changes that were observed during the program were interesting, but
very restrict which makes one wonder about the real effects of this kind of
practice and how much broader changes rely on small individual changes.
Actions that involve information about vocal well-being exclusively should be
revised

Abstract: Background: Sodium metabisulphite (SMBS) is recognized as a
potential cause of airway irritation and possibly occupational asthma, but
awareness of its use in the fishing and fish-processing industry is low. Aims
and methods: To describe three cases of occupational airways disease due to
SMBS exposure and to review the literature. Results: Three patients, one
trawlerman and two prawn processors, developed work-related airways
disease due to exposure to SMBS, one with irritant-induced asthma with a
positive-specific bronchial challenge associated with very high sulphur dioxide
exposures, one with occupational asthma and one with vocal cord dysfunction
and underlying asthma. Of the nine cases recorded in the literature, most
were non- atopic and responses to specific bronchial challenge when
undertaken showed an immediate response. Exposures to sulphur dioxide in
these settings are very high, in excess of 30 ppm. Conclusion: SMBS should
beregarded as a cause of occupational airways disease and its use in the fish
and prawn-processing industry investigated further to better identify risks
from exposure and handling of the agent in the workplace. ® The Author

Ref ID: 416
Abstract: There has been a lack of objective data on the singing voice
registers, particularly on the so called "whistle" register, occurring in the top
part of the female pitch range, which is accessible only to some singers. This
study offers unique strobolaryngoscopic and high- speed (7812.5 imagess)
videokymographic data on the vocal fold behavior of an untrained female
singer capable of producing three distinct voice qualities, i.e., the chest, head
and whistle registers. The sound was documented spectrographically. The
transition from chest to head register, accompanied by pitch jumps, occurred
around tones B4-C#5 (500-550 Hz) and was found to be associated with a
slight decrease in arytenoids adduction, resulting in decrease of the closed
quotient. The register shifts from head to whistle, also accompanied by pitch
jumps, occurred around tones E5-B5 (670-1000 Hz) without any noticeable
changes in arytenoids adduction. Some evidence was found for the vocal tract
influence on this transition. The mechanism of the vocal fold vibration in
whistle register was found principally similar to that at lower registers:
vibrations along the whole glottal length and vertical phase differences
(indicated by sharp lateral peaks in videokymography) were seen on the vocal
folds up to the highest tone G6 (1590 Hz). ® 2008 Acoustical Society of

Abstract: Background: A previous American College of Chest Physicians
Consensus Statement on asthma in the workplace was published in 1995. The
current Consensus Statement updates the previous one based on additional
research that has been published since then, including findings relevant to
preventive measures and work-exacerbated asthma (WEA). Methods: A panel
of experts, including allergists, pulmonologists, and occupational medicine
physicians, was convened to develop this Consensus Document on the
diagnosis and management of work-related asthma (WRA), based in part on a
systematic review, that was performed by the University of Alberta/Capital
Health Evidence- Based Practice and was supplemented by additional
published studies to 2007. Results: The Consensus Document defined WRA to
include occupational asthma (ie, asthma induced by sensitizer or irritant work
exposures) and WEA (ie, preexisting or concurrent asthma worsened by work
factors). The Consensus Document focuses on the diagnosis and management
of WRA (including diagnostic tests, and work and compensation issues), as
well as preventive measures. WRA should be considered in all individuals with
new-onset or worsening asthma, and a careful occupational history should be
obtained. Diagnostic tests such as serial peak flow recordings, methacholine
challenge tests, immunologic tests, and specific inhalation challenge tests (if
available), can increase diagnostic certainty. Since the prognosis is better with
early diagnosis and appropriate intervention, effective preventive measures
for other workers with exposure should be addressed. Conclusions: The
substantial prevalence of WRA supports consideration of the diagnosis in all
who present with new-onset or worsening asthma, followed by appropriate
investigations and intervention including consideration of other exposed
workers. Copyright ® 2008 by American College of Chest Physicians

Abstract: Some categories of workers (actors, teachers, singers) use a
particular working tool: their voice. In order to assess the spread of
dysphonia and its possible causes across a specific class of workers--the
teachers of some schools in the city of Catania--we have set up a ad hoc
questionnaire. A special database has been subsequently arranged, aimed at
the statistical analysis of the responses obtained. The analysis of the
responses shows that the phenomenon is more present in female than male
teachers, 48% versus 30%. The dysphonia occurs mainly at the end of the
working day, lasts throughout the school year and improves in summer,
demonstrating the importance of teaching activity in its pathogenesis. One
aspect especially stands out: dysphonia occurs exclusively in those individuals
suffering from diseases with possible alterations of the voice, such as
allergopathies, tireopathies and gastropathies. Therefore, work activity alone
does not seem able to cause a chronic dysphonia, whereas the presence of
diseases causing disability of vocal cords appears to play an important role

teachers: evaluation of a preventive voice program. J Voice 2007;21:705722.
Ref ID: 435
Abstract: Summary: Vocal education programs for teachers may prevent the
emergence of vocal disorders; however, only a few studies have tried to
evaluate the effectiveness of these preventive programs, particularly in the
long term. Two hundred and sixty-four subjects, mostly kindergarten and
primary school female teachers, participated in a course on voice care,
including a theoretical seminar (120 minutes) and a short voice group therapy
(180 minutes, small groups of 20 subjects). For 3 months, they had to either
attend the vocal ergonomics norms and, as psychological reinforcement, they
had to make out a daily report of vocal abuse, or to follow the given exercises
for a more efficient vocal technique, reporting on whether the time scheduled
was respected or not. The effectiveness of the course was assessed in a group
of 21 female teachers through a randomized controlled study. Evaluation
comprehended stroboscopy, perceptual and electro-acoustical voice analysis,
Voice Handicap Index, and a course benefit questionnaire. A group of 20
teachers matched for age, working years, hoarseness grade, and vocal
demand served as a control group. At 3 months evaluation, participants
demonstrated amelioration in the global dysphonia rates (P = 0.0003), jitter
(P = 0.0001), shimmer (P = 0.0001), MPT (P = 0.0001), and VHI (P =
0.0001). Twelve months after the course, the positive effects remained,
although they were slightly reduced. In conclusion, a course inclusive of two
lectures, a short group voice therapy, home-controlled voice exercises, and
hygiene, represents a feasible and cost-effective primary prevention of voice
disorders in a homogeneous and well-motivated population of teachers.

Ref ID: 81
Abstract: Teachers have a high percentage of voice problems. For voice
disordered teachers, resonant voice therapy is hypothesized to reduce voice
problems. No research has been done on the physiological, acoustic, and
aerodynamic effects of resonant voice therapy for school teachers. The
purpose of this study is to investigate resonant voice therapy outcome from
perceptual, physiological, acoustic, aerodynamic, and functional aspects for
female teachers with voice disorders. A prospective study was designed for
this research. The research subjects were 24 female teachers in Taipei. All
subjects received resonant voice therapy in groups of 4 subjects, 90 minutes
per session, and 1 session per week for 8 weeks. The outcome of resonant
voice therapy was assessed from auditory perceptual judgment,
videostroboscopic examination, acoustic measurements, aerodynamic
measurements, and functional measurements before and after therapy. After
therapy the severity of roughness, strain, monotone, resonance, hard attack,
and glottal fry in auditory perceptual judgments, the severity of vocal fold
pathology, mucosal wave, amplitude, and vocal fold closure in
videostroboscopic examinations, phonation threshold pressure, and the score
39
of physical scale in the Voice Handicap Index were significantly reduced. The
speaking Fo, maximum range of speaking Fo, and maximum range of
speaking intensity were significantly increased after therapy. No significant
change was found in perturbation and breathiness measurements after
therapy. Resonant voice therapy is effective for school teachers and is
suggested as one of the therapy approaches in clinics for this population

Abstract: In order to test the hypotheses that nonsurgical treatment and
elimination of inappropriate use of the voice is sufficient for disappearance of
vocal fold nodules (VN), 28 classical singers with these lesions were examined
for a period of up to 24 years after establishing this diagnosis. Twenty vocally
healthy female singers constituted the control group. Laryngoscopy,
microlaryngoscopy, laryngostroboscopy and acoustic voice analyses were
used to carry out this research. It was found that VN, having once occurred,
tended to reoccur despite nonsurgical treatment and the elimination of
incorrect singing. It was concluded that physiologically correct singing leads
only to a temporary disappearance of soft nodules and does not promote the
resolution of hard nodules

Drummond A. A REVIEW OF THE OCCUPATIONAL DISEASES REPORTING
SYSTEM IN THE REPUBLIC OF IRELAND. 2007.
Ref ID: 483
Abstract: A Review of the Occupational Diseases Reporting System in the
Republic of Ireland. Data on occupational disease are collected for a)
preventive, and b) administrative, legal and/or compensatory purposes. The
need for quality data and statistics to drive a national preventive policy
combined with recent and pending changes in national and international
legislation precipitated this review of national and international systems.
There are many practical and political difficulties associated with estimating
the true extent of the problem of occupational disease and a variety of issues
that continue to cause uncertainty, lack of agreement and debate. The
classification of 'occupational' relates to the cause and not the nature of the
disease, and most countries have drawn up a list of 'prescribed diseases', for
which compensation or benefits are payable. However there are also illnesses
that arise that are related to, even if they cannot be wholly attributed to,
work, and for prevention purposes, it is important that there is a source of
information on these conditions, and that their incidence is monitored. Global
and European agencies have an influence on legal collection requirements and
on how the data are collected. The European legal instrument currently in
place is a Recommendation and therefore not binding on member states.
More recently, the European Commission has proposed a Regulation that will
require member states to provide data on a wider range of conditions that are
work-related. Recent changes to Irish legislation raise a question over what
must be reported as the definition of personal injury has been widened, and
accidents that result in personal injury (and absence) must be reported,
which suggests that accidents resulting in disease or illness must be reported
also. An examination of some of the systems used internationally indicates
that there are many commonalities and some differences. The commonalities
include the use of multiple data sources, and the elusiveness of the 'ideal'
system. Systems in use abroad all have strengths and weaknesses but some
important lesions can be learned from their experience, such as: use multiple
sources, motivate reporters, mandatory reporting to an enforcement authority
results in poor returns, and a pragmatic approach is needed. The occupational
disease data collection capacity and data needs in Ireland were reviewed by
assessing current and potential data sources, current and potential data
collectors and taking into account the views of the end-users of the data.
Primary data collection is carried out by the CSO and the physicians voluntary
reporting scheme; secondary data are available from a variety of other
sources, including the Department of Social and Family Affairs, agencies that
collect health statistics and agencies that collect insurance and claims-based
data. The main issues raised during this review were: 1. The difference
between an occupational disease and a work-related illness and the
implications of the difference. 2. Different occupational and work-related
illness data reporting / collection systems. 3. The characteristics of a 'good'
occupational disease surveillance system. 4. The optimum system of data
collection for prevention purposes in Ireland. 5. The optimum system of data
collection for Ireland to address national and international legislative
requirements

Abstract: Common problems among all patients seen by the laryngologist are
also common among professional voice users. These include
laryngopharyngeal reflux, muscle tension dysphonia, fibrovascular vocal fold
lesions (eg, nodules and polyps), cysts, vocal fold scarring, changes in vocal
fold mobility, and age-related changes. Microvascular lesions and their
associated sequelae of vocal fold hemorrhage and laryngitis due to voice
overuse are more common among professional voice users. Much more
common among professional voice users is the negative impact that voice
problems have on their ability to work, on their overall sense of well-being,
and sometimes on their very sense of self. This article reviews the diagnosis
and treatment options for these and other problems among professional voice
users, describing the relevant roles of medical treatment, voice therapy, and
surgery. The common scenario of multiple concomitant entities contributing to
a symptom complex is underscored. Emphasis is placed on gaining insight
into the "whole" patient so that individualized management plans can be
developed. Videos of select diagnoses accompany this content online

Abstract: OBJECTIVE: To look at the prevalence and impact of voice problems
on teachers and assessing the teachers knowledge on vocal hygiene and
habits, as well as which parameters mostly triggered the seeking of medical
attention and how family doctors could intervene in this spectrum. METHODS:
A survey that consists of 16 questions was used to look at the prevalence and
impact of voice problems on teachers and to identify the associated risk
factors at the American University of Beirut, Lebanon, during the year 2005.
RESULTS: A considerable proportion (46%) perceived their voice as fair or
worse, and 79% had never consulted a throat specialist. Voice disorders
affected most of teachers particularly on their job. The mean number of vocal
habits per person was estimated at 2.4 with smoking being the most common
(38.7%). Two thirds of teachers were unaware of more than half the factors
that can negatively affect their voice. Symptoms exceeding 6 months
significantly increased the probability of consulting a physician by 2.5 folds.
CONCLUSION: Family physicians can reduce the prevalence of vocal
dysfunction in teachers through education and by pointing the various
symptoms necessitating a specialist's early consultation especially when
history of smoking is present

Abstract: Voice disorders are common among teachers, with adverse
consequences for their work and quality of life. This study focuses on factors
associated with voice-related quality of life among female teachers in the
municipal school system in Belo Horizonte, Southeast Brazil. A cross-sectional
study with 2,133 female teachers was conducted, using the Voice-Related
Quality of Life (VRQL) questionnaire, which has two domains: socio-emotional
and physical. Teachers were grouped into quartiles based on the distribution
of the final score in each domain. Those in the lowest quartile were then
compared with all the others for a number of factors, using multiple logistic
regression analysis. Less creativity at work and poor relationship with pupils
were associated with worse voice-related quality of life in both domains.
Mental disorders (GHQ12 > 4) were associated with worse voice-related
quality of life in the socio-emotional domain, and intra-class noise with worse
voice-related quality of life in the physical domain. Improvements in working
conditions are key factors for achieving better voice-related quality of life
among teachers

teacher's voice throughout the career. J Voice 2007;21:316-324.
Ref ID: 82
Abstract: It is generally accepted that vocal performance decreases with age.
This decrease can be expected to be more pronounced in voice loading
professions, which may lead to occupational dysphonia. The aim of this study
was to investigate the course of voice complaints, experienced handicap, and
absenteeism of work due to voice problems throughout the teaching years.
Questionnaires were distributed among teachers of primary and secondary
education, and 1875 were analyzed. The questionnaire was designed in such
a way that personal aspects and questions about periods with symptoms and
absence from work were included. The Voice Handicap Index (VHI) developed
by Jacobson et al was sent along with the questionnaire. Surprisingly, a
significant decrease of voice complaints during the career of the teachers was
observed. The expectation that the percentage of teachers with a history of
voice problems should experience more psychosocial impact, measured with
the VHI, along their professional career could not be confirmed by this study.
These results indicate that serious attention has to be paid to teachers with
voice complaints. The fact that teachers in the beginning of their career
complain more than in the end of their career emphasizes the importance of
adequate aimed prevention programs for future teachers and for starting
teachers with regard to their voice

Abstract: A 39 year male pharmaceutical worker employed in a clean-room
developed in 2003 acute dysphonia after environmental disinfection with
glutaric aldehyde and isopropyl alcohol. Laryngoscopic examination showed
glottis edema; the syndrome healed after a cycle of cortisone. In subsequent
years, withdrawal from exposure to irritating chemicals was observed. The
worker, however, complained for recurrent episodes of dysphonia, in the
absence of abnormalities of the larynx, and gradually developed intolerance
for perfume, solvents, and other smelling substances. He came to our
observation in 2007, showing strong conviction that occupational exposure
had a causative effect in his complaints. He was working in an office open to
public, and fragrance exposure appeared to be the main cause of dysphonic
episodes. We rejected the hypothesis of association between complaint and
job exposure, and advised him to work in a well defined working situation,
such as in a clean room, where chemical contamination may be effectively
controlled over time

Ref ID: 62
Abstract: OBJECTIVES: Vocal cord dysfunction is a poorly understood entity
that is often misdiagnosed as asthma. Both irritant and non-irritant vocal cord
dysfunction have been described. This report presents two cases of irritant
vocal cord dysfunction secondary to specific environmental exposure, the first
to iroko and western red cedar wood (a carpenter) and the second to
xerographic printing toner (a secretary). METHODS: Several tests were
performed, including chest radiographs, measurements of total serum
immunoglobulin E, skin prick tests with common pneumoallergens (as well as
iroko and western red cedar in the first case), pulmonary function studies,
methacholine challenge testing, specific inhalation challenge performed with
suspected agents in a single-blinded fashion, and peak expiratory flow testing
and fiberoptic rhinolaryngoscopy (in case 1). RESULTS: During the specific
inhalation challenge, the patients showed dysphonia, chest tightness,
inspiratory stridor, and flattening of the inspiratory limb of the maximum flowvolume loop in spirometry, with no significant decreases in the level of forced
expiratory volume in 1 second; fiberoptic rhinolaryngoscopy confirmed the
diagnosis of vocal cord dysfunction in case 1. CONCLUSIONS: It is important
43
to know that agents that can cause occupational asthma can also cause vocal
cord dysfunction. The mechanisms by which these agents produce vocal cord
dysfunction are unknown. The differences in the clinical presentation of the
patients described relative to the reported cases suggest that more than one
pathophysiological mechanism may be implicated in the genesis of this entity

Abstract: BACKGROUND: The aim of this study was to assess the application
of Voice Handicap Index (VHI) in the diagnosis of occupational voice disorders
in female teachers. MATERIAL AND METHODS: The subjective assessment of
voice by VHI was performed in fifty subjects with dysphonia diagnosed in
laryngovideostroboscopic examination. The control group comprised 30
women whose jobs did not involve vocal effort. RESULTS: The results of the
total VHI score and each of its subscales: functional, emotional and physical
was significantly worse in the study group than in controls (p < 0.001). The
analysis of VHI-score distribution showed that 68% of female teachers
estimated their own voice problems as a moderate disability, while 12% of
them reported severe voice disability. However, all non-teachers assessed
their voice problems as slight, their results ranged at the lowest level of VHI
score. CONCLUSIONS: This study confirmed that VHI as a tool for selfassessment of voice can be a significant contribution to the diagnosis of
occupational dysphonia

Abstract: BACKGROUND: The aim of this study was to assess the applicability
of Voice Handicap Index (VHI) to the evaluation of effectiveness of functional
voice disorders treatment in teachers. MATERIAL AND METHODS: The
subjects were 45 female teachers with functional dysphonia who evaluated
their voice problems according to the subjective VHI scale before and after
phoniatric management. Group I (29 patients) were subjected to vocal
training, whereas group II (16 patients) received only voice hygiene
instructions. RESULTS: The results demonstrated that differences in the mean
VHI score before and after phoniatric treatment were significantly higher in
group 1 than in group II (p < 0.05). Moreover, the improvement observed
in group I applied to each of VHI subscales: functional, emotional and
physical, while in group II it applied only to physical subscale. CONCLUSIONS:
This study confirmed that the VHI test can be a useful method for monitoring
phoniatric management efficacy in teacher's dysphonia

Ref ID: 56
Abstract: INTRODUCTION: Teachers are at risk of developing voice disorders.
A clinical battery of vocal function tests should include non-invasive and
accurate measurements. The quantitative methods (e.g., voice acoustic
analysis) make it possible to objectively evaluate voice efficiency and
outcomes of dysphonia treatment. MATERIALS AND METHODS: To identify
possible signs of vocal fatigue, acoustic waveform perturbations during
sustained phonation were measured before and after the vocal-loading test in
51 professionally active female teachers with functional voice disorders, using
IRIS software. All the participants were also subjected to
laryngological/phoniatric examination involving videostroboscopy combined
with self-estimation by voice handicap index (VHI)-based scale. RESULTS:
The phoniatric examination revealed glottal insufficiency with bowed vocal
folds in 35.2%, soft vocal nodules in 31.4%, and hyperfunctional dysphonia
with a tendency towards vestibular phonation in 19.6% of the patients. In the
VHI scale, 66% of the female teachers estimated their own voice problems as
moderate disability. An acoustic analysis performed after the vocal-loading
test showed an increased rate of abnormal frequency perturbation parameters
(pitch perturbation quotient (Jitter), relative average perturbation (RAP), and
pitch period perturbation quotient (PPQ)) compared to the pre-test outcomes.
The same was true of pitch-intensity contour of vowel /a:/, an indication of
voice instability during sustained phonation. DISCUSSION AND
CONCLUSIONS: The recorded impairments of voice acoustic parameters
related to vocal loading provide further evidence of dysphonia. The voice
acoustic analysis performed before and after the vocal-loading test can
significantly contribute to objective voice examinations useful in diagnosis of
dysphonia among teachers

Abstract: The occupational voice use of teachers has been an important
research topic over the last 10 years. However, data collection on vocal
loading in teachers at and away from the workplace poses significant
challenges to the research protocol. The challenges include recruitment of
subjects, voice data collection on the job, and subject compliance and
retention. The present article offers recommendations for coping with these
protocol difficulties. The recommendations are based on the authors'
experiences with long-term, on-the-job voice dosimetry of large subject
groups of teachers in the United States and Finland

Abstract: OBJECTIVES: To evaluate and to compare the diagnostic value of
45
videostroboscopy (VS) and high-speed glottography (HGG) in dysphonic
patients. STUDY DESIGN: Randomized, prospective study. METHODS: A total
of 162 patients underwent indirect laryngoscopy using both methods (VS and
HGG). The resulting 324 films were evaluated by two professionals
(laryngologists, MDs) using a standardized protocol containing established
criteria to classify vocal fold vibratory movement qualities. RESULTS: The
rating "not assessable" was mentioned significantly more often in VS than in
HGG (P < .001). In HGG, methodologic failures were less frequent, and the
length of investigation was shorter. Even if the agreement between the two
raters was higher in HGG (54%) compared with VS (42%), both percentage
values show a low accordance in diagnostic findings. CONCLUSIONS:
Regardless of the method used (VS or HGG), perceptive evaluations of
vibratory movements of vocal folds revealed a higher variability than
assumed. This result supports the need for objective methods to analyze
vocal fold vibratory movements. Therefore, real-time imaging of vocal fold
vibratory movements using HGG will be necessary

Ref ID: 53
Abstract: Voice disorders in teachers have a significant impact on their
occupational functioning and well being. Teachers are believed to have a high
prevalence of voice problems because of the unfavourable acoustic
environments in which they work and the high vocal demands and stress
levels associated with teaching. Although the types of voice problems
teachers experience should be preventable because they are caused by
factors that teachers can change, there is limited information available
regarding the effectiveness of different preventative strategies. Therefore, the
aim of this study was to investigate the effectiveness of vocal hygiene training
(VH) and vocal function exercises (VFE) in reducing vocal symptoms and vocal
misuse, and increasing knowledge of voice care, maximum phonation time,
and maximum phonational frequency range in school teachers. Thirty-seven
teachers from four schools in Melbourne, Australia, participated in the study.
Schools were randomly allocated to one of three groups: VH, VFE, and notreatment control. The VH and VFE participants reported improved vocal
characteristics and voice knowledge after training while the control group
showed deterioration on most variables. The VH participants showed greater
improvements than the VFE participants. These fundings indicate that
preventative voice training for teachers is likely to be effective

Abstract: BACKGROUND: Poor voice quality due to a voice disorder can lead
to a reduced quality of life. In occupations where voice use is substantial it
can lead to periods of absence from work. OBJECTIVES: To evaluate the
effectiveness of interventions to prevent voice disorders in adults. SEARCH
STRATEGY: We searched MEDLINE (PubMed, 1950 to 2006), EMBASE (1974 to
2006), CENTRAL (The Cochrane Library, Issue 2 2006), CINAHL (1983 to
2006), PsychINFO (1967 to 2006), Science Citation Index (1986 to 2006) and
the Occupational Health databases OSH-ROM (to 2006). The date of the last
search was 05/04/06. SELECTION CRITERIA: Randomised controlled clinical
trials (RCTs) of interventions evaluating the effectiveness of treatments to
prevent voice disorders in adults. For work-directed interventions interrupted
time series and prospective cohort studies were also eligible. DATA
COLLECTION AND ANALYSIS: Two authors independently extracted data and
assessed trial quality. Meta-analysis was performed where appropriate. MAIN
RESULTS: We identified two randomised controlled trials including a total of
53 participants in intervention groups and 43 controls. One study was
conducted with teachers and the other with student teachers. Both trials were
poor quality. Interventions were grouped into 1) direct voice training, 2)
indirect voice training and 3) direct and indirect voice training combined.1)
Direct voice training: One study did not find a significant decrease of the
Voice Handicap Index for direct voice training compared to no intervention.2)
Indirect voice training: One study did not find a significant decrease of the
Voice Handicap Index for indirect voice training when compared to no
intervention.3) Direct and indirect voice training combined: One study did not
find a decrease of the Voice Handicap Index for direct and indirect voice
training combined when compared to no intervention. The same study did
however find an improvement in maximum phonation time (Mean Difference
-3.18 sec; 95 % CI -4.43 to -1.93) for direct and indirect voice training
combined when compared to no intervention. No work-directed studies were
found. None of the studies found evaluated the effectiveness of prevention in
terms of sick leave or number of diagnosed voice disorders. AUTHORS'
CONCLUSIONS: We found no evidence that either direct or indirect voice
training or the two combined are effective in improving self-reported vocal
functioning when compared to no intervention. The current practice of giving
training to at-risk populations for preventing the development of voice
disorders is therefore not supported by definitive evidence of effectiveness.
Larger and methodologically better trials are needed with outcome measures
that better reflect the aims of interventions

47
targeted at adults with functional dysphonia. For work-directed interventions
interrupted time series and prospective cohort studies were also eligible.
DATA COLLECTION AND ANALYSIS: Two authors independently extracted data
and assessed trial quality. Meta-analysis was performed where appropriate.
MAIN RESULTS: We identified six randomised controlled trials including a total
of 163 participants in intervention groups and 141 controls. One trial was high
quality. Interventions were grouped into 1) Direct voice therapy 2) Indirect
voice therapy 3) Combination of direct and indirect voice therapy and 4)
Other treatments: pharmacological treatment and vocal hygiene instructions
given by phoniatrist.No studies were found evaluating direct voice therapy on
its own. One study did not show indirect voice therapy on its own to be
effective when compared to no intervention. There is evidence from three
studies for the effectiveness of a combination of direct and indirect voice
therapy on self-reported vocal functioning (SMD -1.07; 95% CI -1.94 to
-0.19), on observer-rated vocal functioning (WMD -13.00; 95% CI -17.92 to
-8.08) and on instrumental assessment of vocal functioning (WMD -1.20;
95% CI -2.37 to -0.03) when compared to no intervention. The results of one
study also show that the remedial effect remains significant for at least 14
weeks on self-reported vocal functioning (SMD -0.51; 95% CI -0.87 to -0.14)
and on observer-rated vocal functioning (Buffalo Voice Profile) (WMD -0.80;
95% CI -1.14 to -0.46). There is also limited evidence from one study that
the number of symptoms may remain lower for a year. The combined therapy
with biofeedback was not shown to be more effective than combined therapy
alone in one study nor was pharmacological treatment found to be more
effective than vocal hygiene instructions given by phoniatrist in one study.
Publication bias may have influenced the results. AUTHORS' CONCLUSIONS:
Evidence is available for the effectiveness of comprehensive voice therapy
comprising both direct and indirect therapy elements. Effects are similar in
patients and in teachers and student teachers screened for voice problems.
Larger and methodologically better studies are needed with outcome
measures that match treatment aims. INTERVENTIONS FOR TREATING
FUNCTIONAL DYSPHONIA IN ADULTS: Functional dysphonia is characterised
by an abnormal quality of voice in the absence of an identifiable lesion. People
in occupations where voice use is central, like teachers, are more at risk of
developing functional dysphonia. The causes of voice disorders are still being
debated. There is also no consensus on the best method of evaluating voice,
although many consider auditory voice quality assessment as a gold standard
measure. Because functional dysphonia is a non-organic voice disorder there
is no indication for surgical or medical interventions, and it is treated with
behavioural (i.e. voice) therapy. Voice therapy usually consists of a
combination of direct and indirect treatment techniques. Direct techniques
focus on the underlying physiological changes needed to improve an
individual's technique in using the vocal system whereas indirect techniques
concentrate on contributory and maintenance aspects of the voice disorder
(such as lack of knowledge).We conducted a systematic search of the
literature on treating functional dysphonia in adults. We then appraised the
quality of the studies found and combined their results.A combination of
direct and indirect voice therapy is effective in improving vocal functioning
when compared to no intervention. The achieved results may still be apparent
after a year.Most of the studies are small and of low methodological quality
and further research is warranted

Abstract: The so-called "Ackerman's tumor" is a neoplasm of uncertain
dignity. Aim of this paper is to clarify, whether this is an asbestos-induced
tumor of the larynx in accordance with German regulations for occupational
diseases. A 43-year old male presented the clinical picture of a stenosing
laryngeal tumor. A verrucous neoplasm without a proven malignity in the
sense of an Ackerman's tumor was diagnosed through several sequential
biopsies. Approximately 2 years later a total laryngectomy was performed,
because of a squamous cell carcinoma of the larynx. An occupational disease
in accordance with 4104 BKV was claimed in connection with an asbestos
exposition of 28,3 fibre years (fibres/m3 x years). An Ackerman's tumor is--in
accordance with its definition in the German-speaking area--not conclusively
malignant, there is no indication of a relation between asbestos and such a
tumor in literature, there is no specific benign disorder of the larynx caused
by asbestos. This brings us to the conclusion that the Ackerman's tumor of
the larynx is no asbestos-induced laryngeal tumor as per German
occupational disease regulations

Ref ID: 65
Abstract: The National Center for Voice and Speech (NCVS) data bank on
voice dosimetry was used to study the distributions of continuous voicing
periods and silence periods in 31 teachers over the duration of two weeks.
Recordings were made during all awake hours of the day. Voicing periods
were grouped into half decades, ranging from 0.0316 to 0.10 s for the
shortest periods of phonation to 31.6-100 s for the longest periods of
phonation. Silence periods were grouped into similar half decades, but ranged
up to periods of several hours. On average, the teachers had 1800
occurrences of voicing (onset followed by offset) per hour at work and 1200
occurrences per hour while not at work. Voicing occurred 23% of the total
time at work, dropping to 13% during off-work hours and 12% on weekends.
The greatest accumulation of voicing occurred in the 0.316-1.0 s voicing
periods, whereas the greatest accumulation of silence occurred in the 3-10 s
silence periods. The study begins to lay the groundwork for understanding
vocal fatigue in terms of repetitive motion and collision of tissue, as well as
recovery from such mechanical stress

Several studies have shown that the stress pattern of one's native languageis
applied to new linguistic stimuli. Regarding the segmentation of
artificialsynthesized speech, this idea has been supported by experiments
withlanguages where the stress pattern coincides with word boundaries
(i.e.English, Finnish and Dutch). In this study, we present data on
speechsegmentation with native Spanish speakers whose stress pattern would
markthe penultimate syllable of words. Results show that to stress the
middlesyllable of trisyllabic words in an artificial speech stream does not

Abstract: Chlorine gas inhalation, similar to other toxic gas exposures, can
impart a variety of effects to the entire airway ranging from mucous
membrane irritation to acute respiratory distress syndrome. The extent and
location of damage is determined by numerous situational factors such as the
duration of exposure, quantity of gas released, environmental factors, and
instituted chemical defense measures. Reactive airways dysfunction and
nonspecific bronchial hyperresponsiveness are commonly reported as
sequelae to chlorine exposure. This article constitutes the first case of a single
antecedent chlorine exposure inducing progressive vocal cord dysfunction

Ref ID: 434
Abstract: SUMMARY: Vocal education programs for teachers may prevent the
emergence of vocal disorders; however, only a few studies have tried to
evaluate the effectiveness of these preventive programs, particularly in the
long term. Two hundred and sixty-four subjects, mostly kindergarten and
primary school female teachers, participated in a course on voice care,
including a theoretical seminar (120minutes) and a short voice group therapy
(180 minutes, small groups of 20 subjects). For 3 months, they had to either
attend the vocal ergonomics norms and, as psychological reinforcement, they
had to make out a daily report of vocal abuse, or to follow the given exercises
for a more efficient vocal technique, reporting on whether the time scheduled
was respected or not. The effectiveness of the course was assessed in a group
of 21 female teachers through a randomized controlled study. Evaluation
comprehended stroboscopy, perceptual and electro-acoustical voice analysis,
Voice Handicap Index, and a course benefit questionnaire. A group of 20
teachers matched for age, working years, hoarseness grade, and vocal
demand served as a control group. At 3 months evaluation, participants
demonstrated amelioration in the global dysphonia rates (P=0.0003), jitter
(P=0.0001), shimmer (P=0.0001), MPT (P=0.0001), and VHI (P=0.0001).
Twelve months after the course, the positive effects remained, although they
were slightly reduced. In conclusion, a course inclusive of two lectures, a
short group voice therapy, home-controlled voice exercises, and hygiene,
represents a feasible and cost-effective primary prevention of voice disorders
in a homogeneous and well-motivated population of teachers

measurement of vocal fatigue in classical singers: a vocal dosimetry pilot
study. Otolaryngol Head Neck Surg 2006;135:595-602.
Ref ID: 69
Abstract: OBJECTIVES: To collect objective vibration dose data on singers and
relate them to subjective measurements of vocal fatigue. STUDY DESIGN AND
SETTING: Seven subjects completed a 2-week study period. The National
Center for Voice and Speech (NCVS) dosimeter recorded vocal load, soft
phonation tasks, and subjective soft voice ratings. Three vocal doses (time,
distance, and cycle) were measured in classical singers' larynges during an
intensive practice period. RESULTS: Spikes in vocal load are reflected as
harsher subjective ratings on the same day as well as 24-72 hours later.
When at least 48 hours of vocal rest occurred before a vocal load, improved
subjective evaluations were seen after the load. CONCLUSIONS: The NCVS
dosimeter appears to be an effective tool for data collection on prolonged use
of the voice. SIGNIFICANCE: This is the first multi-day study comparing
objective and subjective data on vocal fatigue in a group of professional
singers

Abstract: OBJECTIVES: We discuss the phonatory characteristics of a
previously undescribed focal laryngeal dystonia present in the singing voice.
METHODS: We performed a retrospective chart review of 5 patients with
singer's dystonia at a neurolaryngology referral center. RESULTS: Four
patients reviewed demonstrated phonatory characteristics consistent with
adductor spasmodic dysphonia present in their singing voice. One patient
demonstrated abductor spasmodic dysphonia in the singing voice. Each
patient initially exhibited normal connected speech in conversational voicing.
The treatment protocol and outcome are discussed, including the use of
botulinum toxin. CONCLUSIONS: Singer's dystonia is a previously undescribed
neurologic disorder that should be understood by those who treat voice
performers and voice disorders

51
instrumentalist and singer. J Voice 2006;20:157-164.
Ref ID: 85
Abstract: Wind instrumentalists, especially brass players, and singers share
common factors, including vocal tract shape, function and pressure, vocal fold
opening and closure, breath vector of force and air flow rates. To understand
the mechanism and function of the vocal folds with a pathological lesion, it is
necessary to visualize the differing interactions of the vocal tract during wind
and brass instrument playing and in singing. A school band director, singer,
wind and brass instrumentalist, was referred by musician colleagues with
intermittent dysphonia, aphonia, and inability to sing high notes.
Simultaneous videolaryngoscopy, with and without stroboscopy, and external
video examination were documented. An hourglass glottis with a sessile,
cystic polyp of the left vocal fold were recorded and studied during phonation
and the playing of 3 instruments. The techniques of glottic opening, closure,
configuration and function varied with the type of instrument and phonatory
function. Singing was adversely affected by the vocal fold polyp but no
harmful interaction occurred during wind/brass instrument playing. Downstream loading in singers is at the laryngeal level and in wind/brass
instrumentalists is at the embouchure. Preoperative voice therapy,
phonomicrosurgery, and postoperative voice rest followed by voice therapy,
succeeded in restoring her combined wind/brass instrumental and singing
career

Cam. Canadian journal of anaesthesia = Journal canadien d'anesthésie

Ref ID: 443
Abstract: PURPOSE: The Airway Cam is a head-mounted direct laryngoscopy
video system which uses a prismatic sighting system that aligns with the
operator's line of sight. This study evaluated intra- and inter-observer
consistency in laryngoscopy grading comparing direct laryngoscopy to the
laryngoscopy grade obtained with the Airway Cam. METHODS: Twenty-seven
patients receiving a general anesthetic for elective surgery had laryngoscopy
performed by an anesthesiologist wearing the Airway Cam. Each video was
duplicated, then randomized and reviewed in a blinded fashion by the original
laryngoscopist and a second anesthesiologist. Intra- and inter-observer
correlations were identified. RESULTS: There was good intra-observer
agreement of the Cormack-Lehane scale between direct laryngoscopy and
laryngoscopy recorded with the Airway Cam (kappa = 0.63). The
corresponding intra-observer correlation of the percentage of glottic opening
score was strong at r = 0.83. There was good inter-observer agreement of
the Cormack-Lehane scale between direct laryngoscopy and that observed by
the second anesthesiologist during Airway Cam video review (kappa = 0.70).
There was moderate correlation of the inter-observer percentage of glottic
opening scores (r = 0.73). CONCLUSION: This study validates that the view
recorded by the Airway Cam reflects the view of the laryngoscopist. The
Airway Cam may introduce an additional level of objectivity into airway
management research and teaching

effectiveness of a voice treatment approach for teachers with self-reported
voice problems. J Voice 2006;20:423-431.
Ref ID: 90
Abstract: SUMMARY: Teachers are considered the professional group most at
risk of developing voice-problems, but limited treatment effectiveness
evidence exists. We studied prospectively the effectiveness of a 6-week
combined treatment approach using vocal function exercises (VFEs) and vocal
hygiene (VH) education with 20 teachers with self-reported voice problems.
Twenty subjects were randomly assigned to a no-treatment control (n = 11)
and a treatment group (n = 9). Fibreoptic endoscopic evaluation was carried
out on all subjects before randomization. Two self-report voice outcome
measures were used: the Voice-Related Quality of Life (VRQOL) and the Voice
Symptom Severity Scale (VoiSS). A Voice Care Knowledge Visual Analogue
Scale (VAS), developed specifically for the study, was also used to evaluate
change in selected voice knowledge areas. A Student unpaired t test revealed
a statistically significant (P < 0.05) improvement in the treatment group as
measured by the VoiSS. There was not a significant improvement in the
treatment group as measured by the V-RQOL. The difference in voice care
knowledge areas was also significant for the treatment group (P < 0.05).
This study suggests that a voice treatment approach of VFEs and VH
education improved self-reported voice symptoms and voice care knowledge
in a group of teachers

Ref ID: 77
Abstract: OBJECTIVES: To report the incidence of allergic rhinitis in singers
with nonspecific laryngeal examination findings and to correlate the incidence
of allergic rhinitis with their vocal symptoms when present. DESIGN: A
retrospective review of all the medical records of singers with nonspecific
laryngeal findings who presented to a specialty voice center for either vocal
training or therapy between June 2002 and September 2005. SETTING:
Specialty voice center. PARTICIPANTS: Forty-five singers with nonspecific
laryngeal findings who presented to a specialty voice center for either vocal
training or therapy. MAIN OUTCOME MEASURES: A standardized validated
questionnaire for evaluation of allergic rhinitis was filled out by all the
subjects. A score above 0 was considered positive. RESULTS: The total
prevalence of allergic rhinitis was 87% (39 of 45 subjects). The singers with
vocal symptoms were approximately 15% more likely to have allergic rhinitis
than those with no vocal symptoms (92% vs 84%). Singers with more than 2
vocal symptoms had a 25% higher likelihood of having allergic rhinitis.
CONCLUSIONS: The incidence of allergic rhinitis in singers is extremely high.
Hidden respiratory allergies may affect the professional voice. Proper
awareness and a multidisciplinary approach are indispensable for proper
diagnosis and treatment

Abstract: The diagnosis of asthma is made easily in most cases and responds
to standard doses of inhaled steroid therapy with or without add-on therapies.
Recent data suggest that almost 80% of asthmatic subjects would have well
controlled disease using combination inhaled steroid and long-acting betaagonists. However, a proportion of adult patients do not respond well, have
poor symptomatic control and are often referred to as having 'difficult
53
asthma'. This poor response to conventional therapy may not always be due
to underlying asthma severity: a number of studies have documented the
frequency of comorbid factors and how targeted intervention affects
outcome in a population of poorly controlled asthmatics. We review these
studies and outline an approach to the patient with difficult asthma

Ref ID: 74
Abstract: Vocal loading-related changes have mainly been investigated in
female voice users. The present study investigated male teachers' voices
before and after a working day. A questionnaire was used to select 22 male
teachers as subjects from a larger group. Ten reported suffering often from
symptoms of vocal fatigue (MC = multiple complaints group), 12 reported few
vocal complaints (FC group). The subjects recorded a text reading sample at
habitual loudness and loudly, and sustained vowel [a:] before and after an
approximately 6-hour working day. Text samples were analyzed for total
sound pressure level (SPL) and SPL at three frequency regions (50-1,000 Hz,
1-2 kHz, 2-5 kHz), fundamental frequency (F0) and alpha ratio [(SPL 1-5
kHz) - SPL (50 Hz-1 kHz)]. Jitter and shimmer were calculated from the
vowel. The subjects filled in a questionnaire about vocal sensations. The MC
group reported more symptoms of vocal fatigue, and the symptoms increased
during the working day. F0 and SPL increased in both groups. Alpha ratio
increased in the MC group but remained the same in the FC group. The MC
group had higher values of jitter and shimmer. Jitter diminished in the FC
group but did not change significantly in the MC group. The differences
between the groups reflect either different strategies for coping with vocal
loading or different loading-induced changes in the vocal organ

Abstract: To enable the development of appropriate diagnostics and treatment
for occupational voice disorders, this study addresses connections between
subjective voice complaints and objective observations. The subjects of this
study were 24 female customer advisors, who mainly use the telephone
during their working hours. During one working day, at four different times,
speech samples covering 20 minutes of telephone conversation by the
customer service advisors (CSAs) were recorded. In addition, the CSAs filled
in a questionnaire (visual analogue scale) concerning their voice problems. To
represent the vocal symptoms three variables were used: vocal fatigue,
hoarseness and a general sum-variable. A 5-minute sample was taken from
recordings for further analyses. This included fundamental frequency, sound
pressure level, alpha ratio (the ratio between the spectral energy below and
above 1000 Hz) and number of vocal fold vibrations. In the objective acoustic
measurements, it was found that fundamental frequency (F0) rose
significantly during the working day. Also the self-reported voice symptoms
increased significantly during the working day. However, correlations between
vocal symptoms and acoustic measures were not found

assessment of migrant worker health and safety risks. 2006. HSE Research
Report RR502.
Ref Type: Report
Ref ID: 484
Abstract: This report, which draws on interviews with 200 migrant workers in
five regions of England and Wales, considers whether the position that recent
migrant workers occupy within the labour market puts their health and safety
at increased risk, in comparison with other workers in similar positions. The
research findings suggest that it is not the case that the risks inherent in a
particular type of work of necessity only present themselves in relation to
migrant workers. However, what it does reveal is that migrants are more
likely to be working in sectors or occupations where there are existing health
and safety concerns and that it is their status as new workers that may place
them at added risk, due to their relatively short periods of work in the UK and
limited knowledge of the UK's health and safety system. The report also notes
that migrant motivations in coming to the UK, particularly where these are
premised on earning as much as possible in the shortest possible time, add to
their risk factors and that limited means of communication between migrant
workers and indigenous supervisors also may place these workers at greater
risk

patients diagnosed with vibroacoustic disease. Rev Port Pneumol
2006;12:375-382.
Ref ID: 71
Abstract: BACKGROUND: Long-term low frequency noise exposure (LFN) (<
or = 500 Hz, including infrasound) may lead to the development of
vibroacoustic disease (VAD), a systemic pathology characterized by the
abnormal growth of extra-cellular matrices. The respiratory system is a target
for LFN. Fibrosis of the respiratory tract epithelia was observed in VAD
patients through biopsy, and confirmed in animal models exposed to LFN.
Voice acoustic analysis can detect vocal fold variations of mass, tension,
muscular and neural activity. Frequency perturbation (jitter), amplitude
perturbation (shimmer) and harmonic-to-noise ratio (HNR) are used in the
evaluation of the vocal function, and can be indicators of the presence and
degree of severity of vocal pathology. Since the respiratory system is the
energy source of the phonation process, this raises questions about the
effects of VAD on voice production. The purpose of this study was to
determine if voice acoustic parameters of VAD patients are different from
normative data. METHODS: Nine individuals (5 males and 4 females)
55
diagnosed with VAD were recorded performing spoken and sung tasks. The
spoken tasks included sustaining vowels and fricatives. The sung tasks
consisted of maximum phonational frequency range (MPFR). Voice acoustic
parameters analysed were: fundamental frequency (F0), jitter, shimmer,
HNR and temporal measures. RESULTS: Compared with normative data, both
males and females diagnosed with VAD exhibited increased F0, shimmer and
HNR. Jitter, MPFR and one temporal measure were reduced. CONCLUSIONS:
VAD individuals presented voice acoustic parameter differences in spectral,
temporal and perturbation measures, which may be indicative of small
morphological changes in the phonatory system

value of voice acoustic analysis in assessment of occupational voice
pathologies in teachers. Logoped Phoniatr Vocol 2006;31:100-106.
Ref ID: 72
Abstract: It has been shown that teachers are at risk of developing
occupational dysphonia, which accounts for over 25% of all occupational
diseases diagnosed in Poland. The most frequently used method of diagnosing
voice diseases is videostroboscopy. However, to facilitate objective evaluation
of voice efficiency as well as medical certification of occupational voice
disorders, it is crucial to implement quantitative methods of voice
assessment, particularly voice acoustic analysis. The aim of the study was to
assess the results of acoustic analysis in 66 female teachers (aged 40-64
years), including 35 subjects with occupational voice pathologies (e.g., vocal
nodules) and 31 subjects with functional dysphonia. The acoustic analysis was
performed using the IRIS software, before and after a 30-minute vocal
loading test. All participants were subjected also to laryngological and
videostroboscopic examinations. After the vocal effort, the acoustic
parameters displayed statistically significant abnormalities, mostly lowered
fundamental frequency (Fo) and incorrect values of shimmer and noise to
harmonic ratio. To conclude, quantitative voice acoustic analysis using the
IRIS software seems to be an effective complement to voice examinations,
which is particularly helpful in diagnosing occupational dysphonia

Ref ID: 60
Abstract: BACKGROUND: An assessment of the vocal system, as a part of the
medical certification of occupational diseases, should be objective and
reliable. Therefore, interest in the method of acoustic voice analysis enabling
objective assessment of voice parameters is still growing. The aim of the
present study was to evaluate the applicability of acoustic analysis with vocal
loading test to the diagnostics of occupational voice disorders. MATERIAL AND
METHODS: The results of acoustic voice analysis were compared using IRIS
software for phoniatrics, before and after a 30-min vocal loading test in 35
female teachers with diagnosed occupational voice disorders (group I) and in
31 female teachers with functional dysphonia (group II). RESULTS: In group
I, vocal effort produced significant abnormalities in voice acoustic parameters,
compared to group II. These included significantly increased mean
fundamental frequency (Fo) value (by 11 Hz) and worsened jitter, shimmer
and NHR parameters. Also, the percentage of subjects showing abnormalities
in voice acoustic analysis was higher in this group. CONCLUSIONS:
Conducting voice acoustic analysis before and after the vocal loading test
makes it possible to objectively confirm irreversible voice impairments in
persons with work-related pathologies of the larynx, which is essential for
medical certification of occupational voice diseases

the percent of the permanent or long-term health damage, which can vary
between 10-40%. The aim of the paper was to analyze the evidence which is
taken into consideration while determining the percent of health damage and
granting the occupational disease pension. The authors present proposition in
detail the rules which govern the process of health damage calculation due to
advancement of voice disorders, which can be very useful to adjudicating
physicians in government and commercial insurance companies

Abstract: Tongue function is seldom studied in relationship to voice emission.
Normal tongue function supports to a varying extent subsequent phases of
voice emission, including respiration, phonation, articulation, and resonance.
Disorders of tongue motoric function lead to difficulties in voice emission at
each of these phases. The disorders vary as to the degree, type, and extent
but in consequence lead to pathologies of the organ of voice. When learning
voice emission, more attention paid to tongue function and its role in voice
formation could improve the training and rehabilitation processes

autonomic stress-related reactivity on vocal endurance in female student
teachers. J Voice 2006;20:242-250.
Ref ID: 92
Abstract: Several studies revealed a high percentage of voice problems in
future teachers. The influence of vocal constitution on the vocal endurance is,
however, still unclear. The goal of this study was to evaluate whether the
increase of voice fundamental frequency (F0) during teaching is caused by (1)
autonomic regulation patterns under stress, (2) anxiety as an emotional
factor, or (3) limitations in voice constitution. Thirty-three subjects with either
normal voice constitution (n = 15, group 1) or constitutional hypofunction (n
= 18, group 2) assessed by voice range profile measurements were enrolled
in this study. Furthermore, they underwent a standardized baseline test to
register selected autonomic test parameters and were classified into
autonomic outlet types (AOT) as proposed by Johannes et al. Later the
subjects were examined during 1 hour of teaching (field study). The
parameters tested included heart rate, pulse transition time, finger
temperature, and voice fundamental frequency. To measure situational
anxiety and general anxiety proneness, a state-trait anxiety inventory was
taken. Eleven subjects per group were identified as autonomic stable (AOT 1),
two per group as responding cardiovascularly (AOT 2), and two of group 1
and four of group 2, respectively, as having higher heart rate and higher
blood pressure responses to stress (AOT 4). One subject had to be excluded
because of missing data. However, statistical analyses showed no differences
between AOT groups regarding the voice constitution groups. Increased
fundamental frequencies of speaking voice after 30 and 45 minutes of
teaching were found in group 2 (constitutional hypofunction). No effect of
state or trait anxiety on voice endurance could be detected. Thus, the
increase of fundamental frequency of voice has to be regarded as a
consequence of vocal fatigue. A constitutionally weak voice seems to be a risk
factor for developing a professional voice disorder

Ref ID: 465
Abstract: Previous studies of students studying to be teachers have indicated
that these students commonly have voice disorders. Ideally, voice disorders
should be treated before students start their work as teachers, but the
resources for this treatment are often limited. This study examines whether
group voice therapy is effective for teacher students. Accordingly, 20 teacher
students with mild voice disorders received group voice therapy (in three
small groups), whereas 20 students with similar voice disorders served as a
control group and consequently did not receive voice therapy. Two out of
three outcome measures (perceptual evaluation of voice quality and a
questionnaire on the occurrence of vocal symptoms) indicated significant
changes in the treatment group compared with the control group. No
differences between groups were noted in the laryngeal status. The results
suggest that group voice therapy seems to be an effective method to treat
students with mild voice disorders

Abstract: INTRODUCTION: In daily phoniatric practice, apart from
laryngoscopy, another simple and useful method of examining the voice organ
is perceptual voice assessment based on the GRBAS scale. An extension to
this examination can be the Voice Handicap Index test (VHI). MATERIALS AND
METHODS: 79 female teachers taking part in a 7-week-long rehabilitation
course on voice emission techniques. Before and after the course the
participants were subject to phoniatric examination including
laryngovideostroboscopy, GRBAS scale assessment and determining the voice
handicap index (VHI). RESULTS: After the course, a substantial improvement
has been observed in voice emission, perceptual assessment and the VHI
test. It has been observed that there is a statistically significant correlation
between GRBAS and VHI results and mean phonation time (MPT) measured
before and after the course. CONCLUSIONS: The VHI test should be included
in complex analysis of the effects of intensive rehabilitation

The study group comprised 425 female full-time teachers (most of them
primary and secondary school, age ranging from 23 to 61 years) and 83 nonteacher women (control) whose jobs did not involve vocal effort, matched for
age to the study group. All participants were subjected to a survey using an
extensive questionnaire, and to laryngological, phoniatric and
videostroboscopic examinations. RESULTS: The overall lifetime vocal
symptoms were more frequent in the teachers than in the non-teachers (69
vs. 36%), and in particular it related to permanent and recurrent hoarseness,
and dryness in the throat. Mean number of the voice symptoms was 3.21 in
teachers and 1.98 in controls (p < 0.001). Abnormal (non-euphonic) voice,
neck muscle hypertension during phonation and incorrect resonator function
were also significantly more frequent in the teachers. Mean maximum
phonation time was shorter in teachers than in the controls (14.3 vs. 15.9 s,
p < 0.01). Occupational voice disorders and hyperfunctional dysphonia
(that is thought to predispose to such pathology) were found in 32.7% of
teachers and 9.6% of control subjects. The probability of developing
incomplete glottal closure (odds ratio 13.2x; 95% CI: 1.8-96.8) and
hyperfunctional dysphonia (odds ratio 2.7; 95% CI: 1.14-6.44) were
significantly higher in the teacher group versus non-teachers. A significant
positive relationship was found in teachers between the prevalence of
hyperfunctional dysphonia and strained phonation, neck muscle hypertension,
instability of voice, self-assessed hyper-arousal, and lifetime vocal effort index
(years of employment as a teacher x hours of professional activity/week). The
59
prevalence of vocal nodules and incomplete glottal closure were correlated
with incorrect phonation technique parameters, but not with psychological
factors. No correlation was found with environmental variables, such as
classroom temperature, humidity, airborne dust. CONCLUSION: The
prevalence of self-reported symptoms and clinical signs of voice disorders is
around 2-3 times more frequent in Polish female teachers than in nonteachers. Lifetime vocal effort, incorrect technique of phonation and
psychological predisposition seem to constitute major risk factors for
developing occupational voice disorders

Pulsed angiolytic laser treatment of ectasias and varices in singers. Ann Otol
Rhinol Laryngol 2006;115:571-580.
Ref ID: 73
Abstract: OBJECTIVES: Varices and ectasias in singers are typically the result
of phonotraumatic shearing stresses and/or collision forces on the
microcirculation within the superficial lamina propria. These lesions can be
debilitating in performing vocalists because of the effect of recurrent
hemorrhage and/or as a contributing factor to the morbidity of other mass
lesions such as polyps, nodules, and cysts. Phonomicrosurgical treatment of
performers is understandably approached with great trepidation, as the vocal
liability of surgically disturbing the superficial lamina propria and epithelium
must be balanced with the inherent detrimental vocal effect(s) of the
lesion(s). Pulsed angiolytic lasers that emit radiation at high absorbance
peaks of oxyhemoglobin were examined to determine whether they were an
efficacious treatment approach for ectasias and varices based on these lasers'
mechanisms of action and prior experience in phonomicrosurgery. METHODS:
A prospective trial was done in 39 patients (40 procedures in 54 vocal folds)
without complication to evaluate the effectiveness of a 585-nm pulsed dye
laser (PDL; 25 cases) and a 532-nm pulsed KTP laser (15 cases) in a
noncontact mode to treat 65 varices and 43 ectasias. Twenty-nine of 39
patients had varices and ectasias associated with other phonotraumatic mass
lesions that required resection. Results: All patients have resumed full vocal
activities, and no patient has had a subsequent hemorrhage or vocal
deterioration. CONCLUSIONS: Both the 585-nm PDL and the 532-nm pulsed
KTP laser were found to be efficacious and relatively safe treatment
modalities for vascular abnormalities of the vocal folds in singers. Noncontact
selective photoangiolysis of the aberrant vessels prevented future bleeding
without substantial photothermal trauma to the overlying epithelium and
surrounding delicate superficial lamina propria, thereby allowing for optimal
postoperative mucosal pliability and glottal sound production. However, the
pulsed KTP laser was substantially easier to use because of its enhanced
hemostasis due to its longer pulse width. Vessel wall rupture was
commonplace during use of the 585-nm PDL, but rarely occurred during
photoangiolysis with the 532-nm pulsed KTP laser

PsychoNeuro 2005;31:307-314.
Ref ID: 356
Abstract: Guidelines regarding technique and dosage of botulinum toxin vary
considerably. One issue remains the role of EMG to refine treatment outcome.
Basically all studies in blepharospasm were conducted without EMG. More
than 60% of patients with cervical dystonia consider Botulinumtoxin even
after years of regular injection sessions every 3 to 4 months as a valuable
treatment and ask for reinjections. The impact of EMG guidance has only
been rarely assessed. The effectiveness of Botulinumtoxin with EMG control in
writer's cramp and in spasmodic dysphonia has been demonstrated in a
number of studies. Refinement of therapy remains a challenge in writer's
cramp and other occupational dystonias, jaw opening dystonia and
anterocollis. EMG guidance may be helpful, probably even a prerequisite in
these indications. The role of EMG guidance in the major indications such as
uncomplicated cervical dystonia and spasticity to improve outcome, minimize
side effects and to save toxin remains unclear

emphysema. J Music Ther 2005;42:20-48.
Ref ID: 98
Abstract: This study investigated the effects of group singing instruction on
the physical health and general wellness of senior citizens with emphysema.
Subjects (n = 7) participated in 6 weeks of group vocal instruction, which
emphasized breath management techniques. Dependent measures reflected
physical health, functional outcomes, and quality of life. No significant
differences were found on measures of physical health (FEV1, inspiratory
threshold, distance walked, and The DUKE physical health subscale).
Measures of functional outcomes each showed a significant change across
time. Results of the ANOVAs for breath management (extent of counting) and
breath support (intensity of speech) were significant (p < .038 & p
< .000 respectively). Descriptive analyses showed a clear and dramatic
shift in breathing mode from clavicular to diaphragmatic breathing that was
maintained 2 weeks after the treatment period. Quality of life measures
(subjective scales and The Duke Health Profile) yielded mixed results.
Findings of this study suggest that vocal instruction, inclusive of breathing
exercises, may help to improve the quality of life for senior citizens with
emphysema. Subjects in this study responded positively to the instruction and
further investigation of the treatment method is warranted

Abstract: OBJECTIVES: This report describes a case of vocal cord dysfunction
at first misdiagnosed as reactive airway dysfunction syndrome (RADS).
METHODS: A woman developed recurrent episodes of cough, dyspnea, and
wheezing unresponsive to asthma therapy after irritant exposure to
glutaraldehyde. Direct laryngoscopy was performed immediately after the
induction of symptoms. RESULTS: Laryngoscopy showed a paradoxical
adduction of the vocal cord on inspiration. Vocal cord dysfunction was
diagnosed. CONCLUSIONS: A case of vocal cord dysfunction occurred after
exposure to glutaraldhyde in a person with a history highly suggestive of
RADS. Vocal cord dysfunction should always be considered in the differential
diagnosis of patients with acute respiratory symptoms after exposure to
irritants and with asthma-like symptoms that fail to respond to conventional
asthma therapy

dysphonia. The Annals of otology, rhinology, and laryngology 2005;114:792798.
Ref ID: 444
Abstract: OBJECTIVES: This study was performed to determine whether and
how unilateral vocal fold paralysis (UVFP) affects the production and
perception of voiced stop consonants as compared with unvoiced stops, and
to analyze the phonetic effects of UVFP on the voicing feature. METHODS:
Phonetic constructs pronounced by 7 male patients with UVFP and 5 normal
male subjects were recorded. The 432 speech tokens consisted of
intervocalic, prevocalic, and postvocalic stop consonants (/p/, /t/, /k/, /b/,
/d/, /g/) in the vowel contexts /a/ and /i/. Perceptual consonant identification
testing was performed with 5 voice and speech professionals as listeners. The
type and frequency of errors made in consonant identification were analyzed.
Spectrographic analysis was used to analyze acoustic cues. RESULTS: The
rate of correct consonant identification was significantly lower for tokens
pronounced by patients with UVFP (77.3% versus 97.6%, p = .0001) because
of incorrect identification of the voiced consonants, frequently perceived as
their unvoiced homologues. Confusion between dental and alveolar place of
articulation for unvoiced stops was also noted. CONCLUSIONS: Unilateral
vocal fold paralysis alters the voiced-unvoiced stop consonant distinction and
the dental-palatal stop consonant distinction in an experimental nonspeech
context. This finding implies the existence of a phonetic handicap for patients
with UVFP. Further studies should determine the effects of UVFP on global
speech intelligibility

tension and body posture in relation to voice handicap and voice quality in
teachers with persistent voice complaints. Folia Phoniatr Logop 2005;57:134147.
Ref ID: 95
Abstract: The aim of this study was to investigate the relationship between
extrinsic laryngeal muscular hypertonicity and deviant body posture on the
one hand and voice handicap and voice quality on the other hand in teachers
with persistent voice complaints and a history of voice-related absenteeism.
The study group consisted of 25 female teachers. A voice therapist assessed
extrinsic laryngeal muscular tension and a physical therapist assessed body
posture. The assessed parameters were clustered in categories. The
parameters in the different categories represent the same function. Further a
tension/posture index was created, which is the summation of the different
parameters. The different parameters and the index were related to the Voice
Handicap Index (VHI) and the Dysphonia Severity Index (DSI). The scores of
the VHI and the individual parameters differ significantly except for the
posterior weight bearing and tension of the sternocleidomastoid muscle.
There was also a significant difference between the individual parameters and
the DSI, except for tension of the cricothyroid muscle and posterior weight
bearing. The score of the tension/posture index correlates significantly with
both the VHI and the DSI. In a linear regression analysis, the combination of
hypertonicity of the sternocleidomastoid, the geniohyoid muscles and
posterior weight bearing is the most important predictor for a high voice
handicap. The combination of hypertonicity of the geniohyoid muscle,
posterior weight bearing, high position of the hyoid bone, hypertonicity of the
cricothyroid muscle and anteroposition of the head is the most important
predictor for a low DSI score. The results of this study show the higher the
score of the index, the higher the score of the voice handicap and the worse
the voice quality is. Moreover, the results are indicative for the importance of
assessment of muscular tension and body posture in the diagnosis of voice
disorders

acoustic parameters in female teachers with diagnosed occupational voice
disorders]. Med Pr 2005;56:431-438.
Ref ID: 80
Abstract: BACKGROUND: Laryngovideostroboscopy is the method most
frequently used in the assessment of voice disorders. However, the
employment of quantitative methods, such as voice acoustic analysis, is
essential for evaluating the effectiveness of prophylactic and therapeutic
activities as well as for objective medical certification of larynx pathologies.
The aim of this study was to examine voice acoustic parameters in female
teachers with occupational voice diseases. MATERIALS AND METHODS:
Acoustic analysis (IRIS software) was performed in 66 female teachers,
including 35 teachers with occupational voice diseases and 31 with functional
dysphonia. RESULTS: The teachers with occupational voice diseases
presented the lower average fundamental frequency (193 Hz) compared to
the group with functional dysphonia (209 Hz) and to the normative value (236
Hz), whereas other acoustic parameters did not differ significantly in both
groups. CONCLUSIONS: Voice acoustic analysis, when applied separately from
vocal loading, cannot be used as a testing method to verify the diagnosis of
occupational voice disorders

Abstract: OBJECTIVE: The aim of this study was calculate the prevalence and
incidence of voice disorders among teaching staff of La Rioja, Spain. DESIGN:
We carried out a transversal study of voice disorders in teaching staff of La
Rioja (a random sample of 931 of 3113 teachers) and a longitudinal study
(we collect the new cases during the 3 years which lasts the study).
PATIENTS: 527 teachers of random sample took part of study: 332 female
(63%) and 195 male (37%). METHODS: All of teachers fill in a standard
63
questionnaire, ENT and function vocal examination, videolaryngostroboscopy
and acoustic analysis with MDVP. RESULTS: The prevalence of voice disorders
among La Rioja Teachers was 57%: 20.3% for organic lesions [nodular
lesions (14%), polyps (2%), submucous suffusions (1.4%), edema Reinke
(1.2%) Sulcus (0.4%), scalp (0.6%), leucoplasia (0.2%) vocal cord paralysis
(0.2%)] 8.1% for chronic laryngitis [not specific (2.8%), smoke (3.9%)
gastroe-sofageal reflux (2.5%)] and 29% for functional lesions
[hyperfunctional dysphonia (7.5%) hypofunctional dysphonia (0.4%) vocal
overefforts (18%) hyperplasia false cords (2.8)]. The incidence rate was 4
new cases each 1000 teachers and year. CONCLUSIONS: Organic lesions were
more prevalent in women (25.4%) than in men (9.5%), but functional lesions
and chronic laryngitis were more prevalent in men (36.5% and 13.2%) than
in women (24% and 5%)

children's processing of spoken language? J Voice 2005;19:47-60.
Ref ID: 100
Abstract: There is a vast body of literature on the causes, prevalence,
implications, and issues of vocal dysfunction in teachers. However, the
educational effect of teacher vocal impairment is largely unknown. The
purpose of this study was to investigate the effect of impaired voice quality on
children's processing of spoken language. One hundred and seven children
(age range, 9.2 to 10.6, mean 9.8, SD 3.76 months) listened to three video
passages, one read in a control voice, one in a mild dysphonic voice, and one
in a severe dysphonic voice. After each video passage, children were asked to
answer six questions, with multiple-choice answers. The results indicated that
children's perceptions of speech across the three voice qualities differed,
regardless of gender, IQ, and school attended. Performance in the control
voice passages was better than performance in the mild and severe dysphonic
voice passages. No difference was found between performance in the mild
and severe dysphonic voice passages, highlighting that any form of vocal
impairment is detrimental to children's speech processing and is therefore
likely to have a negative educational effect. These findings, in light of the high
rate of vocal dysfunction in teachers, further support the implementation of
specific voice care education for those in the teaching profession

Abstract: The number of diagnosed instances of larynx cancer is
systematically increasing, especially in men. Treatment, in the majority of
cases, is undertaken at an advanced stage of the disease. This is the major
factor determining the outcome of therapy and the patients' quality of life.
The aim of this paper is to estimate the environmental and occupational risk
factors as well as to evaluate the quality of life of patients before they were
diagnosed with larynx cancer and after the treatment was completed. The
analysis involved 82 patients after total laryngectomy due to squamous cell
carcinoma. A vast majority of the patients (96%) abused alcohol and were
heavy smokers (95%). 76% were exposed to harmful environmental
conditions and 56% - to harmful conditions at workplace. After treatment,
which was accepted by over 96% of the patients, many of them quit using
alcohol (57%) and quit smoking (73%). Because of difficult economic
situation only few of them decided to change their working or living
conditions. 47% of patients judged that after the diagnosis and consequently
after undergoing complete treatment, the quality of their life deteriorated.
Their awareness of the health-threatening factors had however grown

Abstract: The objective of the study was to assess voice capabilities and
laryngeal abnormalities in female teaching students in order to evaluate risk
factors of future occupational voice disorders. One hundred forty-four women
(aged 17 to 41 years) were examined using videostroboscopy and voice range
profile measurements. Stroboscopically, the subjects were classified into three
groups depending on the shape of the glottal closure. Thirty-five phonationassociated alterations and six organic alterations of the vocal folds were
found. Subjects with an insufficient glottal closure showed a higher
percentage of phonation-associated vocal fold alterations (i.e. vocal nodules)
and reached lower maximum sound pressure levels. The results underline the
necessity to execute vocal examinations and vocal assessment analyses for
candidates of voice intensive professions in order to avoid profession-related
dysphonias at a later stage

Abstract: The purpose of this prospective study was to evaluate microsurgical
thyroidectomy by comparing it with traditional thyroidectomy. Before surgery,
patients were assigned either to the microscopic thyroidectomy group (MT
group), with the use of the surgical microscope, or the traditional
thyroidectomy group (TT group), without the use of visual magnification.
Outcome measures were operative time, intraoperative bleeding and
complication rates including injury to the recurrent laryngeal nerve (RLN), the
external branch of the superior laryngeal nerve (EBSLN) or the parathyroid
glands. Ninety-eight patients underwent thyroid surgery (58 patients in the
MT group, 40 patients in the TT group). The two groups were similar in age,
sex, surgical procedures and histological findings. There was no difference
65
between the two techniques regarding the operative time and the amount of
blood loss. Neither permanent nerve palsy nor persistent hypocalcemia
occurred in either group. Transient nerve palsies (RLN and EBSLN) were lower
in the MT group (1.7%) compared to the TT group (7.5%), but the difference
did not reach statistical significance (P>0.05). Overall transient hypocalcemia
was significantly lower in the MT group (1.7%) compared with the TT group
(12.5%, P=0.032). If the population was restricted to total thyroidectomy, the
rate of transient hypocalcemia was 4.1% in the MT group and 33.3% in the
TT group, respectively (P=0.022). In conclusion, microsurgical thyroidectomy
is a feasible and efficacious surgical procedure. It significantly reduces the
complications without increasing the operating time in thyroid surgery
procedures. A major advantage of this technique is the possibility of attaching
a camera to the microscope, thereby greatly facilitating teaching

symptoms among teachers during a twelve-year period. J Voice 2005;19:95102.
Ref ID: 99
Abstract: Vocal symptoms and voice disorders among teachers were studied
in 1988 using a questionnaire designed to obtain information on six vocal
symptoms that had appeared during the past 2 years. Twelve percent of the
478 respondents reported vocal symptoms occurring weekly or more often.
The study was repeated using the same questionnaire in 2001. The results of
this second study (n=241) indicate that vocal symptoms had increased
considerably. Twenty-nine percent of the teachers reported symptoms
occurring weekly or more often, and 20% reported two symptoms or more
occurring at least once a week, which is significantly more than in 1988.
Accordingly, voice disorders are probably a growing problem among teachers.
Several factors may explain these increases. In 2001, the teachers
complained more often about increases in the size of their classes. Factors
that disturbed normal work routines, such as noisy or misbehaving pupils,
had also increased significantly. A growing number of misbehaving pupils
probably cause increased background noise and stress and, thus, increase the
vocal symptoms in teachers

Ref ID: 79
Abstract: OBJECTIVES: It has been decided to identify the most frequent
diseases of the larynx in people occupationally exposed to a considerable
voice load and to assess the feasibility of using videostroboscopy to diagnose
voice disorders and their organic effects in order to improve the reliability of
certification of occupational vocal organ diseases as well as to evaluate the
functioning of new regulations on diagnosing and certifying occupational vocal
organ diseases and to assay the conformity of clinical diagnoses made at
voivodeship (provincial) centers (level I) with those made at scientific
research institutes (level II). MATERIALS AND METHODS: The study involved
an analysis of 1261 cases (1042 women and 219 men) with the vocal organ
disorders referred to the ENT Unit, Nofer Institute of Occupational Medicine,
Lodz, by voivodeship centers during 1999-2004 for consultation or under the
appeal procedure (if applicants were denied the right to be included in the
category of patients with occupational disease of the vocal organ). The
majority of the patients (65.7%) were primary school teachers, and those
aged 51-60 years made 54.8%. Laryngological, phoniatric and
videostroboscopic examinations, when necessary, supplemented with other
testing procedures (paranasal sinus imaging, allergenic tests) were taken to
assess the clinical state of the patients. RESULTS: As a result of these
comprehensive examinations, organic changes in the larynx were detected in
161 (12.7%) cases, including 139 (11.0%) women and 22 (1.7%) men.
According to current diagnostic/certifying criteria those pathologies could be
classified into the category of occupational disease of the vocal organ. Paresis
of vocal folds due to the insufficiency of vocal fold adductor and tensor
muscles with permanent dysphonia was found in 97 (7.6%) patients, vocal
nodules in 53 (4.2%) and secondary hypertrophy changes in vocal folds in 11
(0.87%) patients. The most frequent reasons for excluding the occupational
etiology of the disease were functional disorders of the voice observed in
82.3% of patients in the form of hyperfunctional dysphonia (64.3%),
hypofunctional dysphonia (17.0%) and dysfunctional dysphonia (about
1.0%). In 9.0% of patients, the functional disorders of the voice were
accompanied by organic changes in the larynx caused by non-occupational
factors. CONCLUSIONS: The analysis showed that due to new Polish
regulations, the number of certified occupational disease of the vocal organ
was reduced; videostroboscopic tests proved to be a very helpful tool for
discriminating between the functional and organic disorders of the vocal
organ; and good agreement between clinical diagnoses issued at both levels
(I and II) was also revealed

singers. Curr Opin Otolaryngol Head Neck Surg 2005;13:138-142.
Ref ID: 96
Abstract: PURPOSE OF REVIEW: In this article, we illustrate the evolution of
studies that contribute to a better understanding of vocal care for professional
voice users and singers in particular. RECENT FINDINGS: Research on vocal
hygiene is specific, focusing on concrete solutions. It has commonly been
believed that hydration and vocal rest are beneficial; recent research proves
this supposition. An exhaustive medical diagnosis and careful therapy is
stressed to detect and treat any micro-organic lesions caused by reflux,
infection, allergy and environmental circumstances, which can harm a singer's
voice. The use of medication is reviewed and side effects are evaluated.
SUMMARY: Vocal coaches, speech therapists and otolaryngologists need to
focus more specifically on the management of vocal care. Accurate medical
diagnosis and specific guidelines for singers must be provided as higher voice
67
demands imply more profound and structured voice care. In the past, vocal
hygiene had a negative connotation; a more positive and supporting approach
to voice care, with more attention to the singer, is recommended

Ref ID: 436
Abstract: STUDY OBJECTIVES: To study endotracheal tube (ETT) cuff
pressures during nitrous oxide (N2O) anesthesia when the cuffs are inflated
with air to achieve sealing pressure, and to evaluate the frequency of
postoperative laryngotracheal complaints. DESIGN: Prospective, randomized,
blind study. SETTING: Metropolitan teaching hospital. PATIENTS: 50 ASA
physical status I and II patients scheduled for elective abdominal surgery.
INTERVENTIONS: Patients received standard general anesthesia with 66%
N2O in oxygen. In 25 patients, the ETT cuff was inflated with air to achieve a
sealing pressure (Pseal group). In 25 patients, the ETT cuff was inflated with
air to achieve a pressure of 25 cm H2O (P25 group). MEASUREMENTS AND
MAIN RESULTS: ETT intracuff pressures were recorded before (control) and at
30, 60, 90, 120, and 150 minutes during N2O administration. We investigated
the frequency and intensity of sore throat, hoarseness, and dysphagia in
patients in the Post-Anesthesia Care Unit (PACU) and 24 hours following
tracheal extubation. The cuff pressures in the Pseal group were significantly
lower than in the P25 group at all time points studied (p < 0.001), with a
significant increase with time in both groups (p < 0.001). The cuff pressures
exceeded the critical pressure of 30 cm H2O only after 90 minutes in the
Pseal group and already by 30 minutes in the P25 group. The frequency and
intensity of sore throat, hoarseness, and dysphagia were similar in both
groups in the PACU and 24 hours after tracheal extubation (p > 0.05).
CONCLUSIONS: Minimum ETT sealing cuff pressure during N2O anesthesia did
not prevent, but instead attenuated, the increase in cuff pressure and did not
decrease postoperative laryngotracheal complaints

promoted before a problem occurs. To investigate the primary prevention of
occupational dysphonia among teachers, this study uses a sample population
of 55 training teachers, in the postgraduate certificate of education (PGCE)
course at the University of Ulster, Northern Ireland, who were randomly
assigned to three training groups: control, indirect, and direct. The vocal
performance of the three groups was measured at two points over the year of
the PGCE course: first before any teaching or training began, and again after
the first teaching practice. The training for the indirect and direct groups was
provided before the teaching practices. Acoustic and self-perceptual
measurements were used to assess the multidimensional outcomes. The
results demonstrate interesting trends, that although not found to be
significant, are approaching significance. Their voices will be reevaluated at a
third point of measurement. The acoustic measurement reflects deterioration
from time 1 to time 2 for the control group, improvement for the direct group,
and no change for the indirect group, indicating that the training has proved
beneficial. The self- rating scores vary in agreement with the acoustic results,
presenting interesting findings. The findings of this study will be of benefit to
teachers, their educators, voice therapists, health promoters, and human
resource personnel

Abstract: OBJECTIVE: The objective of the study was to evaluate factors
predisposing to occupational dysphonia in a group of professional voice users.
MATERIAL AND METHODS: The study involved 374 patients treated in the
Clinic of Otolaryngology and the Phoniatric Outpatient Clinic, Department of
Otolaryngology, Medical University of Bialystok in 1999--2001. Group I
consisted of 309 patients qualified as professional voice users. The obtained
results were compared with those yielded in a group of 65 persons of other
occupations (group II). All the diagnosed patients neither smoked nor abused
alcohol. Tobacco smokers, patients with chronic diseases of the respiratory
system or individuals exposed to irritating vapors were excluded from the
study. The clinical evaluation included phoniatric examinations with use of
videoendoscopy (VIS) and videolaryngostroboscopy (VLSS) of the larynx.
Based on the larynx endoscopic image the voice organ pathology was
diagnosed in the patients as functional and/or organic dysphonia. The former
comprised hyperfunctional or hypofunctional dysphonia and insufficiency of
the glottis and the latter other laryngeal disturbances. In the statistical
analysis chi2 parametric test of independence for two averages was used.
RESULTS AND CONCLUSIONS: Female teachers of primary and lower
secondary schools, mean age 43 years, prevailed in the group of professional
voice users, in which functional dysphonia was more common. In this group,
69
the onset of organic changes was earlier than that of functional changes and
was manifested by soft vocal nodules, edematous and inflammatory changes
in the vocal fold mucosa. Functional dysphonia of 3 degrees, 4 degrees and
even 5 degrees predominated in the group of professional voice users in the
course of their employment

Abstract: Occurrence of professional dysphonia was analysed in a group of
309 patients treated in the Phoniatric Outpatient Clinic, Department of
Otolaryngology, Medical Academy in Bialystok through the period of 19992001. In a group of professional voice users female teachers of primary
schools and lower secondary schools predominated. Obtained results were
compared with those from a group of 65 persons of other occupations. In the
both groups other harmful factors affecting the voice organ were excluded.
The clinical assessment included subjective and objective laryngological
examination using videolaryngostroboscopy. The clinical material was
evaluated in a view of functional and organic disorders of the voice organ.
Early occurrence and aggravation of functional changes in the larynx was
recorded in non professional voice users in the course of their seniority. In
professional patients organic changes were more common and occurred
earlier than functional disorders. Severity of dysphonia was related to the
larynx pathology, especially of a functional character

of Reincke's edema among different professional groups: Presentation of

Ref ID: 380
Abstract: Objectives: Reincke's edema is one of the most common voice
disorders in adults. The main purpose of our study, was to analyze factors
that may influence the development of this disease. We also estimated the
results of surgical treatment. Materials and Methods: The research was
performed on a group of 261 patients with Reincke's edema treated in the
ENT Department of the Medical University of Wroclaw in the years 1994-2000.
In the study population, women were in a majority and teachers formed the
largest occupational group (30%) followed by salespersons (15%). Most of
the patients (86%) were tobacco smokers. All of the patients underwent
detailed videostroboscopic examination of the larynx and perceptual analysis
of the voice quality before and after treatment. Results: The symmetry of
vocal cords before and after treatment was found in 75 patients. Lack of
symmetry before treatment, and proper symmetry after surgery was
observed in 71 subjects. Fifty patients showed less symmetry after treatment,
and 65 patients were asymmetric before and after surgery. The difference
between the symmetry of vocal folds before and after treatment was at the
border of statistical significance (p = 0.069). The number of patients with full
vocal cords closure increased after treatment. This difference was statistically
significant (p = 0.032). The periodicity of vocal cord movements was
significantly higher after treatment (p < 0.001). Conclusions: The perceptual
assessment of voice, before and after treatment, revealed statistically
significant post-treatment improvement in voice quality

Abstract: A questionnaire designed to assess vocal demands and vocal health
was completed by 438 randomly selected auctioneers. Over 96% reported
using amplification to auction the majority of the time. A greater proportion of
individuals who auctioned in environments with poor air quality visited a
physician for a voice problem than individuals who auctioned in environments
with clean air. Significant contributors to vocal quality changes and vocal
fatigue were frequency of auctioning, as well as auctioning in noise. In
addition, the duration of auctioning without a break significantly contributed
to vocal fatigue. Vocal hygiene recommendations are provided based on these
findings

Abstract: Dysphonia has an occupational view nowadays. A shift in the voiceoriented professional's clinical approach has been required. New voiceoriented job categories have emerged and, as a result, the voice disorder in
the professional enviroment has increased. The economic and productivity
harm due to voice disorders are a preocupation. Dysphonia has multiple
causes and its evaluation, ethiological conclusion and occupational reports
aren't defined yet. Aim: In order to obtain a more accurate and
comprehensive evaluation, a multidisciplinary protocol was elaborated to
ensure proper medical scientific support. It consists of anamnesis, physical
exam, laryngeal endoscopy, perceptive voice analysis and Voice Handicap
Index application (VHI). Study design: Transversal historic cohort. Material e
mqtodo: In this preliminary study, the protocol was applied on 15 voice
professionals with dysphonia. Results: 13,3% with normal voice performance;
33,3% with functional dysphonia; 46% with organic dysphonia. Dysphonia
was related to the voice-oriented job in 40% cases and it was ruled out in
46,6%. Conclusion: We concluded that the protocol is complete enough to
help otolaryngologists evaluate this workers' category

Ref ID: 108
Abstract: Over 3 million teachers in the United States use their voice as a
primary tool of trade and are thought to be at higher risk for occupationrelated voice disorders than the general population. However, estimates
regarding the prevalence of voice disorders in teachers and the general
population vary considerably. To determine the extent that teachers are at
greater risk for voice disorders, 2,531 randomly selected participants from
Iowa and Utah (1,243 teachers and 1,288 nonteachers) were interviewed by
telephone using a voice disorder questionnaire. Prevalence-the number of
cases per population at risk at a specific time-was determined. The
71
prevalence of reporting a current voice problem was significantly greater in
teachers compared with nonteachers (11.0% vs. 6.2%), chi(2)(1) = 18.2, p
<.001, as was the prevalence of voice disorders during their lifetime
(57.7% for teachers vs. 28.8% for nonteachers), chi(2)(1) = 215.2, p
<.001. Teachers were also significantly more likely than nonteachers to
have consulted a physician or speech-language pathologist regarding a voice
disorder (14.3% vs. 5.5%), chi(2)(1) = 55.3, p <.001. Women, compared
with men, not only had a higher lifetime prevalence of voice disorders (46.3%
vs. 36.9%), chi(2)(1) = 20.9, p <.001, but also had a higher prevalence of
chronic voice disorders (>4 weeks in duration), compared with acute voice
disorders (20.9% vs. 13.3%), chi(2)(1) = 8.7, p =.003. To assess the
association between past voice disorders and possible risks, adjusted odds
ratios (ORs) were estimated using multiple logistic regression. The results
identified that being a teacher, being a woman, being between 40 and 59
years of age, having 16 or more years of education, and having a family
history of voice disorders were each positively associated with having
experienced a voice disorder in the past. These results support the notion that
teaching is a high-risk occupation for voice disorders. Important information
is also provided regarding additional factors that might contribute to the
development of voice disorders

Abstract: To examine the frequency and adverse effects of voice disorders on
job performance and attendance in teachers and the general population,
2,401 participants from Iowa and Utah (n1 = 1,243 teachers and n2 = 1,279
nonteachers) were randomly selected and were interviewed by telephone
using a voice disorder questionnaire. Teachers were significantly more likely
than nonteachers to have experienced multiple voice symptoms and signs
including hoarseness, discomfort, and increased effort while using their voice,
tiring or experiencing a change in voice quality after short use, difficulty
projecting their voice, trouble speaking or singing softly, and a loss of their
singing range (all odds ratios [ORs] p <.05). Furthermore, teachers
consistently attributed these voice symptoms to their occupation and were
significantly more likely to indicate that their voice limited their ability to
perform certain tasks at work, and had reduced activities or interactions as a
result. Teachers, as compared with nonteachers, had missed more workdays
over the preceding year because of voice problems and were more likely to
consider changing occupations because of their voice (all comparisons p
<.05). These findings strongly suggest that occupationally related voice
dysfunction in teachers can have significant adverse effects on job
performance, attendance, and future career choices

Abstract: Occupational voice disorders have been increasing for years. The
aim of this study was to examine whether a constitutionally weak voice
should be regarded as a risk factor for developing such voice disorders. In a
prospective study, 15 female teacher students with a normal vocal
constitution were compared with 18 students with constitutionally weak
voices during teaching practice. There was a significant difference in the mean
fundamental frequency of both groups after teaching for 30 min. Students
with constitutionally weak voices tended to have increased values. Taking into
consideration the physiological aspects of an increasing fundamental
frequency as a sign of vocal fatigue, a constitutionally weak voice has to be
regarded as a potential risk factor for developing a voice disorder in vocally
intensive occupations. To prevent future vocal problems by appropriate
prophylactic intervention (i.e. voice therapy, introduction to vocal hygiene), a
phoniatric examination of vocal constitution and endurance is recommended
at the beginning of a voice dependent professional career

Abstract: PURPOSE: This study was designed to determine the occupational
risk factors associated with voice disorders among schoolteachers, a high-risk
population for developing voice problems. METHODS: Telephone interviews
were completed by 1243 teachers from Utah and Iowa. Response rates were
98% and 95%, respectively. Bivariate analyses were computed and assessed
using chi-square test and Cochran-Mantel-Haenszel test, and logistic
regression analyses were performed and resulting odds ratios assessed using
95% confidence intervals. RESULTS: Teachers of vocal music, drama, other
performing arts and chemistry were at significantly greater risk of having a
voice disorder (OR=2.2, 95% CI: 1.2-4.0; OR=2.1, 95% CI: 0.9-4.8;
OR=1.6, 95% CI: 1.0-2.4; OR=2.0, 95% CI: 1.1-3.4), while teachers of
special and vocational education had a significantly lower risk (OR=0.5, 95%
CI: 0.3-0.7; OR=0.6, 95% CI: 0.4-0.9). When adjusted for the intensity of
vocalization, only teachers of chemistry were significantly at risk (OR=2.0,
95% CI: 1.1-3.5) while teachers of special education continued to have less
of a risk (OR=0.5, 95% CI: 0.4-0.8). Chronic voice disorders were more
prevalent among teachers of vocal music (OR=4.1, 95% CI: 2.2-7.9) and less
73
prevalent among teachers of vocational education (OR=0.29, 95% CI: 0.090.95). CONCLUSIONS: These findings suggest that teachers of specific
courses are at greater risk of developing a voice disorder

professions. Folia Phoniatr Logop 2004;56:220-253.
Ref ID: 105
Abstract: A well-functioning voice is an essential tool for one third of the
labour force. Vocal demands vary to a great extent between the different
voice and speech professions. In professions with heavy vocal loading (e.g.
school and kindergarten teachers), occupational voice disorders threatening
working ability are common. Vocal loading is a combination of prolonged voice
use and additional loading factors (e.g. background noise, acoustics, air
quality) affecting the fundamental frequency, type and loudness of phonation
or the vibratory characteristics of the vocal folds as well as the external frame
of the larynx. The prevention and treatment of occupational voice disorders
calls for improved occupational safety and health (OSH) arrangements for
voice and speech professionals. On the basis of epidemiological and acousticphysiological research, the presence of risk to vocal health can be
substantiated. From the point of view of the physical load on the vocal
apparatus, loading-related physiological changes (adaptation) may play a role
in the occupational risk. Environmental factors affect vocal loading changes.
In teaching professions, the working environment is shared with children, who
benefit from amendments of OSH legislation concerning their teachers

Abstract: Critical illness polyneuropathy (CIP), a neurologic complication that
may occur secondary to cardio-respiratory distress, surgery, trauma and
coma, is associated with sepsis or multiple organ failure. CIP is characterized
by an axonal distal degeneration of sensory and motor fibres. The patients
will often become neurologically conspicuous when weaning from mechanical
ventilation is unexpectedly difficult. There are just a few cases reported with
description of the functional outcome and rehabilitation issues of this
condition. An additional CIP case of a 62-year old man complicated with
anoxic brain damage during the respiratory distress is reported here. He was
referred for rehabilitation, made a remarkable recovery (FIM gain 45!) and
returned home after 79 days of treatment in the ward. A review of the
pertinent literature is provided. Rehabilitation specialists and other
professionals working within ICU's should be aware of this condition and be
able to recognize and treat CIP at early possible stage

Ref ID: 119
Abstract: OBJECTIVE: To investigate the effect of exposure to occupational
agents on the risk of hypopharyngeal/laryngeal cancer. METHODS: Casecontrol study conducted during 1979-1982 in six centres in South Europe. An
occupational history and information on exposure to non-occupational factors
were collected for 1010 male cases of hypopharyngeal/ laryngeal cancer as
well as for 2176 population controls. The exposure to 10 occupational agents
was assessed through a job-exposure matrix. As occupational histories had
been collected since 1945 major analyses were restricted to subjects aged
less than 55 years (315 cases and 819 controls). RESULTS: Significant
elevated risks adjusted for non-occupational variables (smoking, alcohol
consumption and diet) and other occupational exposures were consistently
found for organic solvents (odds ratio (OR) for ever-exposure: 1.7, 95%
confidence interval: 1.1-2.5) and asbestos (OR: 1.6, 1.0-2.5). A significant
positive trend for both probability of exposure and duration was found for
exposure to solvents. A positive association between exposure to
formaldehyde and laryngeal cancer was also suggested. No association was
found for exposure to arsenic and compounds, chromium and compounds,
and polycyclic aromatic hydrocarbons. Analyses restricted to subjects aged 55
or more did not show elevated risks, with the exception of wood dust (OR:
1.8, 1.3-2.7). CONCLUSIONS: In our study occupational exposure to solvents
was associated with an increased risk of hypopharyngeal/laryngeal cancer.
Results also provide additional evidence of an excess of risk for exposure to
asbestos

Abstract: OBJECTIVE: To estimate risks for laryngeal/hypopharyngeal cancer
associated with occupational titles and industrial activities. METHODS: A
multicentre population-based case-control study was conducted in the early
1980s in six southern European areas. Analyses included 1010 male cases
and 2176 controls. Odds ratios (ORs) (adjusted for age, study area, tobacco
consumption, and alcohol consumption) were estimated for 156 occupations
75
and 70 industrial activities. RESULTS: An excess risk has been confirmed for
categories of construction workers, potters (OR: 5.91, 95% confidence
intervals 1.46-24.0), butchers (2.53, 1.22-5.22), barbers (2.33, 1.00-5.40),
laborers not otherwise specified (1.52, 1.12-2.06), as well as for men who
had been employed in railway transport (1.52, 0.97-2.39), shipbuilding (2.05,
0.89-4.94), and hotels (2.06, 0.89-4.75). An association was also found for
shoe finishers (3.23, 0.75-13.9), loggers (2.07, 0.87-4.90), and some groups
of metal workers. ORs for loggers, butchers, railway transport workers,
laborers, and reinforced concreters increased with duration of employment.
The suggestion of a risk for machine operators among woodworkers (3.10,
0.92-10.5) conflicts with previous findings. No significant excess of risk was
found for categories previously reported to be associated with laryngeal and
hypopharyngeal cancer, such as drivers, mechanics, welders, machinists, and
painters. CONCLUSIONS: The present study provides additional evidence to
the hypothesis of a risk of cancer of the larynx/ hypopharynx for workers
engaged in jobs in the construction, metal, textile, ceramic, and food
industries and in railway transport. Loggers were also found at risk; a
previously unreported finding

A case control study design]. Acta Otorrinolaringol Esp 2003;54:253-260.
Ref ID: 118
Abstract: Vocal nodules are structural lesions very common amongst
professional voice users such as teachers. We have studied the risk factors
that predispose the development of vocal nodules in teachers. Two hundred
and forty-two teachers were selected: 120 with vocal nodules and 120 with
normal vocal folds. Professional and personal factors as well as classroom
environment were studied. A complete evaluation of the voice was performed,
aerodynamic measures, tone and extension of the voice, acoustic analysis,
perceptual evaluation of the voice as well as a videolaryngostroboscopy which
was definitive in the diagnosis. Younger teachers with less years of teaching
experience a greater have tendency to develop vocal nodules than the rest.
Class-room's dryness, loudness and echo are correlated with the pathological
group. The most relevant personal factors in the pathological group were
previous vocal pathology, laryngeal surgery, nasal surgery and
gastroesophageal reflux. Vocal intensity and vocal frequency ranks were
shorter in the pathological group. We could also see that, fonatory flow was
less effective in the pathological group

Abstract: Voice problems are a common occupational hazard of teaching
school, yet few studies exist that have objectively evaluated treatment
approaches aimed at rehabilitating these occupation-related voice disorders.
This randomized clinical trial used patient-based treatment outcome measures
to evaluate the effectiveness of three treatment programs. Sixty-four
teachers with voice disorders were randomly assigned to 1 of 3 treatment
groups: voice amplification using the ChatterVox portable amplifier (VA; n =
25), resonance therapy (RT; n = 19), and respiratory muscle training (RMT; n
= 20). Before and after a 6-week treatment phase, all teachers completed (a)
the Voice Handicap Index (VHI; B. H. Jacobson et al., 1997), an instrument
designed to appraise the self-perceived psychosocial consequences of voice
disorders, and (b) a voice severity self-rating scale. Both intention-to-treat
and as-treated analyses revealed that only the VA and RT groups reported
significant reductions in mean VHI scores and in voice severity self-ratings
following treatment. Furthermore, results from a posttreatment questionnaire
regarding the perceived benefits of treatment showed that compared to RT
and RMT, teachers in the VA group reported significantly more overall voice
improvement, greater vocal clarity, and greater ease of speaking and singing
voice following treatment. These findings replicate previous results from an
earlier clinical trial confirming the efficacy of VA and provide new evidence to
support RT as an effective treatment alternative for voice problems in
teachers. The results are discussed in the context of uneven levels of selfreported compliance and disparate dropout rates among the treatment groups

Patients except pharmacological treatment and physiotherapy realised the
course of voice emission exercises under speech therapist supervision. Ninety
teachers were examined before and after treatment. Laryngological,
phoniatric and laryngostroboscopic studies were carried out. In most patients
phoniatric assessment revealed elongation of phonation time, changing of
breathing route from cleidocostal to phrenocostal and voice creation without
neck muscle tension after completing of treatment. 6 weeks lasting period of
exercises was determined to be sufficient in most patients to learn correct
breathing and phonation but to establish normal voice emission patient strong
motivation, discipline and regularity during several months lasting exercises is
needed

Abstract: The results of the preliminary analysis of the risk of lung and larynx
cancers among coal miners in Upper Silesia are presented. The risk increases
substantially during the work under conditions of short-lived radon progeny
hazard, especially when the concentration of alpha potential energy of shortlived radon progeny is higher than 2.5 (microJ m(-3)) that corresponds to the
possibility of receiving the effective dose higher than 6 mSv y(-1). Significant
differences of the risk are noticed between sub-populations of autochthonminers and immigrant-miners: it was found that the relative risk for
immigrant-miners was up to 2 times higher than for autochthon-miners

professional female singer. J Voice 2003;17:283-297.
Ref ID: 116
Abstract: Understanding how the voice is used in different styles of singing is
commonly based on intuitive descriptions offered by performers who are
proficient in only one style. Such descriptions are debatable, lack
reproducibility, and lack scientifically derived explanations of the
characteristics. We undertook acoustic and aerodynamic analyses of a female
subject with professional experience in both operatic and Broadway styles of
77
singing, who sang examples in these two styles. How representative the
examples are of the respective styles was investigated by means of a listening
test. Further, as a reference point, we compared the styles with her speech.
Variation in styles associated with pitch and vocal loudness was investigated
for various parameters: subglottal pressure, closed quotient, glottal leakage,
H1-H2 difference (the level difference between the two lowest partials of the
source spectrum), and glottal compliance (the ratio between the air volume
displaced in a glottal pulse and the subglottal pressure). Formant frequencies,
long-term-average spectrum, and vibrato characteristics were also studied.
Characteristics of operatic style emerge as distinctly different from Broadway
style, the latter being more similar to speaking

Ref ID: 417
Abstract: Long-term recordings with reliable methods are desirable for
objective documentation of voice use during natural conditions. The purpose
of this study was to evaluate a voice accumulator (VAC) with a digital
audiotape (DAT) recorder as a reference. The VAC is based on a
microprocessor that accumulates information about fundamental frequency
(F0) and phonation time. A contact microphone attached to the front of the
neck registers vocal fold vibrations. The DAT recorder was connected to two
microphones for airborne signals placed at equal distance from the mouth
close to the subject's ears. The computer program Aura was used to separate
the subject's voice from the background noise. The Soundswell program was
used for F0 and phonation time analysis. Two tests were performed: 1) One
female speech-language pathologist was recorded with the two devices
simultaneously in a sound-proof booth. She read a standard text with
different voice qualities and sustained vowels with increasing F0 and intensity
separately. The results showed good agreement between the two methods
with respect to F0 and phonation time. However, the VAC failed to register
high frequencies above around 440 Hz as well as low intensities. 2) Three
female pre-school teachers were recorded with the two devices
simultaneously during a working day. Results showed high correlations
between the two methods in terms of long-term measurements of F0 and
phonation time for two subjects. For one subject with subcutaneous soft
tissue on the neck, the registration with the contact microphone was not
reliable. It was concluded that the VAC has potential for assessment of
occupational voice disorders if certain limitations of the method are
considered

Abstract: Confidently establishing the diagnosis of occupational asthma (OA)
is a complicated undertaking, because it requires that the patient's asthma
symptoms are caused exclusively (or at least in large part) by occupational
exposures. Asthma is a common disease, and the differential diagnosis of
asthma is a frequently discussed subject that includes common and
uncommon disorders. This article presents a broad characterization of OA,
including the elements necessary to establish a diagnosis. Differential
diagnosis also is discussed

Abstract: Vocal fatigue is a complex multifaceted clinical phenomenon.
Several hypotheses exist concerning its underlying mechanism, and a range
of empirical studies have examined its manifestation. This article reviews the
literature pertaining to the nature, underlying processes, and salient features
of vocal fatigue. First, vocal fatigue is defined, its major symptoms are
discussed, and hypotheses concerning its primary physiological and
biomechanical mechanisms are considered. Second, studies of experimentally
induced vocal fatigue in humans are evaluated. Third, research investigating
the clinical and occupational manifestations of vocal fatigue is discussed.
Fourth, directions for ongoing research in this area are offered

ULDs? Occup Med (Lond) 2003;53:452-455.
Ref ID: 114
Abstract: BACKGROUND: Voice recognition systems (VRS) allow speech to be
converted both directly into text-which appears on the screen of a computerand to direct equipment to perform specific functions. Suggested applications
are many and varied, including increasing efficiency in the reporting of
radiographs, allowing directed surgery and enabling individuals with upper
limb disorders (ULDs) who cannot use other input devices, such as keyboards
and mice, to carry out word processing and other activities. Aim This paper
describes four cases of vocal dysfunction related to the use of such software,
which have been identified from the database of the Voice and Speech
Laboratory of the Massachusetts Eye and Ear infirmary (MEEI). METHOD: The
database was searched using key words 'voice recognition' and four cases
were identified from a total of 4800. RESULTS: In all cases, the VRS was
supplied to assist individuals with ULDs who could not use conventional input
devices. Case reports illustrate time of onset and symptoms experienced.
CONCLUSION: The cases illustrate the need for risk assessment and
consideration of the ergonomic aspects of voice use prior to such adaptations
being used, particularly in those who already experience work-related ULDs

literature. Occup Med (Lond) 2003;53:456-460.
Ref ID: 113
Abstract: BACKGROUND: Occupational voice health is becoming more
important as more people rely on their voices for their work. A number of
studies have identified certain occupational groups at increased risk of
developing occupational voice disorders, namely teachers, singers and
aerobics instructors. Aim The paper aims to review the literature on
occupational groups at risk of voice disorders and identify areas for future
research. METHOD: A literature review of key databases using key words such
as 'occupational', 'voice health', 'voice loss', 'dysphonia' and 'work related'
was undertaken. RESULTS: The review identified case reports, studies of
79
attendees at hospital voice clinics and a few cross-sectional studies of
occupational groups in the workplace. There were no longitudinal studies
found or intervention studies looking at reduction of risk. CONCLUSION:
Further research on occupational voice disorders needs to be based in the
workplace, and to look at the risk factors for the development of voice
problems and for the efficacy of controls

Abstract: The upper airway plays a critical role in filtering and conditioning air
for the lungs. It provides the first line of warning and defense against
microbials, allergens, and toxic inhalants. Current evidence suggests that the
upper airway is susceptible to many of the pathogenic processes that the
agents cause in the lower respiratory tract. Work-related rhinosinusitis or
vocal cord dysfunction should prompt physicians and employers to identify the
injurious agent(s) and formulate strategies to eliminate or reduce such
exposures. Improving the work environment will prevent the development of
new cases and the worsening of symptoms in existing cases

syndrome? Arch Mal Prof Med Trav 2002;63:87-90.
Ref ID: 347
Abstract: Our attention has recently been drawn by a case of persistent
dysphonia in a grainstore worker suffering from occupational asthma. The
fiberoptic visualization of a paradoxical movement of the vocal cords raised
the diagnosis of an irritant-associated vocal cord dysfunction. This recently
described entity is discussed here. The dysfunction of vocal cords not due to
irritants can create a multitude of clinical signs during the crises such as
cough, short breath and more rarely hoarseness, dysphonia, and difficulties in
swallowing. As in our case, a chronic cough or hoarseness can be the only
observed manifestations. Different activating factors were previoulsy studied.
The strong clinical resemblance to asthma makes all the difficulty of this
pathology. A delay diagnosis of 4.8 years on average when the dysfunction is
isolated can be observed. This problem is frequent because 56 % out of the
95 cases of vocal cords dysfunction studied by Newman were associated with
asthma. The diagnosis is authenticated thanks to direct or indirect laryngeal
fiberscopy or better, to video - laryngoscopy which allows the observation of a
paradoxical lock of the anterior two thirds of the vocal cords during the
respiratory cycle with the persistant opening of a laryngeal posterior
rhombus. In every case the therapeutic approach consists in reassuring the
patient. In the long run, the coverage consists of sessions of speech therapy
based on learning diaphragmatic breathing in order to stop focusing on the
larynx and in psychological conversations when a favorable ground is
suspected

Abstract: Whether physiologically correct singing promotes disappearance of
vocal nodules (VN) was studied in 27 professional classic style singers having
VN for 20 years. VN arose primarily in women, tended to recur. As shown by
examination with laryngostroboscope, electroglottograph and sound level
meter, physiologically correct singing resulted in temporary disappearance of
soft nodules but hard nodules did not resolve. It is inferred that professional
singing is not recommended for subjects with hard vocal nodules

with voice abuse. Folia Phoniatr Logop 2002;54:2-7.

Abstract: Fifteen vocally abusive and 15 healthy female classical singers were
examined before and outside menses by means of laryngoscopy,
laryngostroboscopy and electroglottography. Investigation before menses
revealed more extensive alteration of the larynx in vocally abusive singers
than in healthy ones. Subsequent investigation, after the inappropriate use of
their voice had been eliminated, indicated decreased changes to the larynx. It
was concluded that premenstrual hyperchanges were a result of combined
abuse- and menses-related influence on the larynx, and that laryngeal
examination before menstruation could be a useful test for the presence of
physiologically correct singing

Ref ID: 139
Abstract: The incidence of occupational diseases is one of the basic indices of
the effectiveness of prevention in the area of occupational health. It allows for
the identification of jobs, plants and branches of the national economy with
potentially increased risks for pathologies induced by working conditions.
However, we should be aware of the fact that many of the recently diagnosed
diseases result from long-term exposures experienced at work sites which are
no longer under operation. The analysis was based on data included in
occupational disease certificates. All sanitary and epidemiological stations
throughout the country are committed to notify cases of occupational
diseases to the National Register of Occupational Diseases at the Nofer
81
Institute of Occupational Medicine in Lodz. After a significant increase in the
number of occupational diseases (8305-12,017 cases per year) observed in
1980-1998, its decrease has been noted in Poland over the recent two years
(9982 cases in 1999 and 7339 in 2000). In 1998-2000, a substantial decrease
in the decreasing rate was also found (from 117.3 to 73.9 per 100,000
employed), which means that the decreasing trend does not result only from
the increasing size of the working population in Poland. In 2000 like in
previous years, among occupational diseases the following ones were most
often diagnosed: diseases of vocal organ due to excessive voice effort most
common in teachers, occupational hearing loss, pneumoconiosis, contagious
and invasive diseases, dermatoses, chronic diseases of bronchi, vibration
syndrome as well as acute and chronic poisonings. There were registered
6626 cases of the above listed diseases, that is 90.3% of all occupational
diseases. In 1998-2000, a significant decrease in the incidence of this
category of diseases was noted. The largest decrease applied to the vocal
organ diseases, occupational hearing loss and contagious and invasive
diseases (by 30%, 51% and 40%, respectively). Neither in the member
states of the European Union, nor in the USA, vocal organ pathologies are
listed among occupational diseases. The main reason for this is an
inappropriate medical prevention in the group of teachers and somewhat
limited opportunity to teach them how to use techniques of voice emission. A
decreased incidence of occupational diseases observed in Poland in 19982000 results partly from improvements in working conditions and partly from
more effective prevention

Ref ID: 140
Abstract: Professional voice users often present to otolaryngologists and
laryngologists with specific voice complaints. The contributions of pathologic
lesions to the patients' vocal complaints are not always clear on examination,
and often, premorbid examinations of the larynx are not available for review.
This study examines the incidence of laryngeal pathology among singing
teachers. At a national convention of singing teachers, volunteers were
recruited for a "free strobovideolaryngoscopic examination." All volunteers
completed a detailed questionnaire of their vocal and medical history and
underwent strobovideolaryngoscopic examination. Strobovideolaryngoscopic
examinations were completed in 20 volunteers, 7 of whom had voice
complaints and 13 of whom perceived their voices to be normal. Vocal fold
masses were common among the asymptomatic singing teachers. Evidence of
reflux laryngitis was a common finding among both symptomatic and
asymptomatic singing teachers. Asymmetries in vocal fold hypomobility were
more common among those with voice complaints than was the presence of
vocal fold masses in the population studied
(212) Kaplan MB, Ward DS, Berci G. A new video laryngoscope-an aid to intubation
and teaching. J Clin Anesth 2002;14:620-626.
Ref ID: 124
Abstract: In recent decades, video techniques have been employed in the
majority of endoscopic procedures because of several distinct advantages
provided. These include the following: The displayed anatomy is magnified.
Recognition of the anatomical structures and anomalies is easier, and
manipulation of airway devices is facilitated. When assistance is required, the
operator and assistant can coordinate their movements because each sees
exactly the same image on the video monitor. As a result, video techniques
have become the method of choice in teaching. The Video Macintosh
Intubating Laryngoscope System (VMS) was designed employing a standard
Macintosh blade and laryngoscope handle. A camera was incorporated into
the handle with a short image and light bundle. The magnified anatomy is
displayed on an 8-inch monitor, which is attached to a swivel arm on a small
cart. Observation and manipulation can be performed in one axis.A total of
235 patients were studied and were divided into two groups: Group A (n =
217), in whom intubation was thought unlikely to be difficult, and Group B (n
= 18), in whom difficulty with intubation was anticipated. External laryngeal
manipulation (ELM) was required in 22 of the 217 Group A patients (10%). All
intubations but one in this group were successful. In the second group (B) of
18 patients who had anatomical conditions that suggested that direct
laryngoscopy might be challenging, all 18 cases required ELM but all were
successfully intubated using the VMS. The improved coordination afforded by
an image on a video monitor seen by both the assistant providing laryngeal
manipulation and the anesthesiologist handling the laryngoscope results in a
significant advantage over the conventional laryngoscope technique. As a
consequence, the learning curve is short. In our view, video laryngoscopy will
become the method of choice in teaching

and histopathologic aspects. Am J Otolaryngol Head Neck Med Surg

Ref ID: 384
Abstract: Purpose: The purpose of this study was to evaluate retrospectively
the distribution of histologic damage and its correlation with various risk
factors in a group of patients affected by Reinke's edema. Materials and
Methods: The study subjects comprised 125 patients with bilateral Reinke's
edema consecutively presenting at the Department of Otorhinolaryngology,
"La Spienza" University, Rome. The patients were divided into 4 groups
according to Hellquist, Lundgren, and Olofsson's histologic classification and
were then further categorized according to the number of cigarettes they
smoked daily. Average exposure to cigarette smoke, occupation, habitual
voice use, and gastroesophageal reflux were also considered. Results: Fiftytwo patients did not exhibit histologic lesions, 64 patients were histologically
classified as Group 1 (epithelial hyperplasia and/or keratosis with or without
mild dysplasia), and 6 patients exhibited moderate dysplasia (Group 2) . In 3
patients, histologic examination showed evidence of unilateral carcinoma in
situ (Group 3). Forty-four patients suffered recurrences within the first 2.5
years. Both daily cigarette consumption and duration of exposure to cigarette
smoke were found to influence the severity of the histologic lesion. An
association with gastroesophageal reflux was observed in 4 patients (3.2%).
Prolonged vocal abuse did not prove to be a noteworthy factor in our study.
Conclusions: The main risk factor for Reinke's edema and for its recurrence is
tobacco use. Our study results showed that the clinical manifestation of this
disease is related to the number of cigarettes smoked daily and the duration
of exposure to smoke. Longer durations of exposure to cigarette smoke result
in higher degrees of histologic damage

Ref ID: 129
Abstract: One of the problems confronted in the teaching profession is the
maintenance of a healthy voice. This basic pedagogical tool is subjected to
extensive use, and frequently suffers from overload, with some teachers
having to give up their profession altogether. In some teacher training
schools, it is the current practice to examine the student's voice, and to refer
any perceived susceptibility to strain to voice specialists. For this study, a
group of vocally healthy students were examined first at the teacher training
schools, and then at the ENT clinic at the University Hospital of Nijmegen. The
aim was to predict whether the subject's voice might be at risk for
occupational dysphonia as a result of the vocal load of the teaching
profession. We tried to find objective measures of voice quality in student
teachers, used in current clinical practice, which reflect the judgements of the
therapists and phoniatricians. We tried to explain such measures
physiologically in terms of robustness of, and control over voicing. Objective
measures used included video-laryngostroboscopy, phonetography and
spectrography. Maximum phonation time, melodic range in conjunction with
maximum intensity range, and the production of soft voice are suggested as
possible predictive parameters for the risk of occupational voice strain

Ref ID: 127
Abstract: Vocal nodules (singer's nodules) are a typical professional disease of
the vocal apparatus. This disease occurs more frequently in 20- to 50-yearold singers. The nodules form because of vascular disorders secondary to
overstrain of the vocal apparatus in phonation and disorders of vegetative
innervation. 43 opera singers were treated whose age and singing history
ranged from 22 to 57 years and 3 to 26 years, respectively. The treatment
combined psychotherapy, medicines with phlogenzym as a basic drug,
physiotherapy and phonopedia. Phlogenzym allows to avoid "silence regimen",
surgical intervention. This improves treatment efficacy, shortens the time of
disability for singers

Abstract: The Central Register of Occupational Diseases keeps the records of
all reported and certified occupational diseases in Poland. In this paper the
incidence of occupational diseases in Poland in 2001 is discussed on the basis
of the data provided by the Register. The changes in the incidence pattern
over the recent 30 years are also shown. In 2001, 6007 cases of occupational
diseases were registered, with the incidence rate of 63.2 per 100 000
employees. The highest incidence rates were noted for seven categories of
diseases: the vocal organ diseases, noise-induced hearing loss,
pneumoconioses, contagious and invasive diseases, dermatoses, chronic
diseases of bronchi, and vibration syndrome. Altogether these diseases
covered 5239 cases (87.2% of all registered cases). Mining and quarrying,
agriculture, hunting and forestry, education, health and social works were the
economy activities with the highest incidence of occupational diseases. The
majority of occupational diseases (93.9%) have developed after a long-term
(over 10 years) exposure to particular harmful factors. As much as 58.5% of
cases were recorded in males. The predominant occupational diseases in
males were occupational hearing lesions, while in females chronic vocal organ
diseases, most common in teachers, were most frequently recognized. In
Poland, the diseases of the vocal organ poses a serious problem from the
medical and socio- economic points of view. These pathologies show the
highest dynamics of the incidence among all registered occupational diseases.
Over the last five years the vocal organ diseases have moved upwards to the
top in the ranking, both with respect to the number of cases and the
incidence rate. Since 1998, the incidence of occupational diseases has been
continuously showing a downward tendency. Four categories of occupational
diseases have accounted mostly for this decline: noise- induced hearing loss,
chronic diseases of vocal organ, contagious and invasive diseases, and
dermatoses (a decrease by 64%, 54%, 40%, and 51%, respectively). The
decreased incidence has been also noted for "classical pathologies": chronic
poisonings, pneumoconioses and vibration syndrome. At least three most
important explanatory factors have to be pointed out: a) the decrease in
employment and liquidation of industrial plants with the highest health risk;
b) the modernization of plants and improvement of working conditions; and c)
effective prevention

Abstract: In 1975 to 2000 in the Czech Republic 247 occupational vocal
disorders were notified as occupational diseases. They included above all
severe hyperkinetic dysphonia, nodes on the vocal cords, severe
incompetence of the vocal cords or severe phonasthenia. Detailed analysis of
occupational diseases notified by the Clinic of Occupational Diseases in Brno
revealed that during the mentioned period 30 occupational vocal disorders
were notified. In 26 instances women were involved. Teachers were affected
most frequently - a total of 28. The disease was diagnosed and notified on
average after 21.2 years of work in the occupation pretentious on the voice.
The mean age of the subjects was 44.6 years. The authors describe the
symptoms and development of occupational vocal disorders and their
evaluation. They describe also principles of prevention. They submit a list of
occupations where we can speak of vocal profesionals, incl. quantification of
demands on vocal functions

frequency (F0), sound pressure level (SPL), the standard deviations of these
values (F0 SD; SPL SD) and F0 time (vibration time of vocal folds) were
made. The most obvious change due to loading was the rise of F0 that was
9.7 Hz between the first and last lesson (P = 0.00). F0 increased more (12.8.
Hz, P = 0.006) in the subgroup with few complaints

Ref ID: 460
Abstract: OBJECTIVE: To assess the effect of amnioinfusion during labour with
meconium stained amniotic fluid on caesarean section rate and perinatal
outcome. DESIGN: Prospective randomised controlled study. SETTING: A
tertiary care teaching hospital in India. POPULATION: Women in labour at
term with meconium stained amniotic fluid. METHODS: Two hundred women
in labour with > or = 37 weeks gestation, single cephalic presentation with
moderate or thick meconium were randomised to control and amnioinfusion
groups at a 1:1 ratio. Amnioinfusion was performed using 500 mL of normal
saline over a period of 30 minutes in a study group. The control group
received routine care. Both groups had intermittent auscultation of fetal heart
rate during labour. MAIN OUTCOME MEASURES: The primary outcome
measure was caesarean section rate. Secondary outcome measures were
meconium aspiration syndrome, 1 minute and 5 minute apgar < 7, hypoxic
ischaemic encephalopathy, neonatal intensive care unit admission, meconium
at the level of vocal cords. RESULTS: The caesarean section rate in the
amnioinfusion group was less than the control group (RR 0.47; 95% CI 0.240.93). Amnioinfusion was associated with a significant decrease in the
incidence of meconium at the vocal cords (P = 0.001); improvement in 1
minute apgar scores (P < 0.05), respiratory distress (P = 0.002) and fewer
admissions to nursery compared with the controls. This sample size was
inadequate to study the impact on meconium aspiration syndrome.
CONCLUSION: Amnioinfusion in an under resourced labour ward decreases
caesarean section rates and fetal morbidity

instruction for teachers with voice disorders: a treatment outcomes study. J
Speech Lang Hear Res 2002;45:625-638.
Ref ID: 137
Abstract: Voice problems are common among schoolteachers. This
prospective, randomized clinical trial used patient-based treatment outcomes
measures combined with acoustic analysis to evaluate the effectiveness of
two treatment programs. Forty-four voice-disordered teachers were randomly
assigned to one of three groups: voice amplification using the ChatterVox
portable amplifier (VA, n = 15), vocal hygiene (VH, n = 15), and a
nontreatment control group (n = 14). Before and after a 6-week treatment
phase, all teachers completed: (a) the Voice Handicap Index (VHI), an
instrument designed to appraise the self-perceived psychosocial consequences
of voice disorders; (b) a voice severity self-rating scale; and (c) an
audiorecording for later acoustic analysis. Based on pre- and posttreatment
comparisons, only the amplification group experienced significant reductions
on mean VHI scores (p = .045), voice severity self-ratings (p = .012), and
the acoustic measures of percent jitter (p = .031) and shimmer (p = .008).
The nontreatment control group reported a significant increase in level of
vocal handicap as assessed by the VHI (p = .012). Although most pre- to
posttreatment changes were in the desired direction, no significant
improvements were observed within the VH group on any of the dependent
measures. Between-group comparisons involving the three possible pairings
of the groups revealed a pattern of results to suggest that: (a) compared to
the control group, both treatment groups (i.e., VA and VH) experienced
significantly more improvement on specific outcomes measures and (b) there
were no significant differences between the VA and VH groups to indicate
superiority of one treatment over another. Results, however, from a
posttreatment questionnaire regarding the perceived benefits of treatment
revealed that, compared to the VH group, the VA group reported more clarity
of their speaking and singing voice (p = .061), greater ease of voice
production (p = .001), and greater compliance with the treatment program (p
= .045). These findings clearly support the clinical utility of voice amplification
as an alternative for the treatment of voice problems in teachers

psychodynamic model. J Voice 2002;16:544-548.
Ref ID: 125
Abstract: Psychogenic voice disorders are not infrequently encountered in the
busy voice clinic. A clinician-friendly psychodynamic model and a
multidisciplinary management approach are presented which have proven
helpful for our voice team and our patients. In essence the formulation
revolves around an "event" occurring, which may be either organic or
psychological in nature. The ensuing dysphonia then leads to emotional
consequences which in turn have physical consequences on the vocal tract.
The situation can become reinforcing and illness behaviors develop.
Elucidating this event/process to the patient improves the likelihood of a
successful long-term outcome. The diagnostic and management roles of the
various team members are discussed

teachers. Logoped Phoniatr Vocol 2002;27:21-28.
Ref ID: 133
Abstract: Day care center teachers suffer from voice disorders more often
than nurses do. Several risk factors may increase voice disorder prevalence of
day care center teachers. The risk factors can be bound to their job content
and manner of working i.e. having to raise their voice to attract the attention
of the children and to offer them the possibility to perceive spoken
information, or to the environment i.e. poor acoustics and excess background
noise. The purpose of this study was to measure some of the risk factors for
voice disorders of day care center teachers and of a control group (nurses);
these were speaking times and speech levels. The background noise levels
during activities and RASTI-values (Rapid Speech Transmission Index), i.e.
measures of the acoustics of rooms, were also measured at the day care
centers. It was found that day care center teachers use their voices more and
with higher levels than nurses do. It was also found that the background
noise levels are high, which is partly due to the poor acoustics (lack of
sufficient attenuation) of the rooms. Control of excess background noise is of
utmost importance both for speakers' speech production as well as children's
speech recognition

Abstract: Vocal fatigue is a frequently reported voice symptom among
professional voice users. Indian school of teachers continuously for many
hours in adverse acoustical environments and are highly susceptible to vocal
fatigue. The present study is the first to examine acoustic voice measures in
teachers reporting naturally induced vocal fatigue. 40 female primary school
of teachers (mean age = 36 years) with varying severity of vocal fatigue
participated in this study. Voice measures of minimum and maximum
fundamental frequency were obtained before and after one and a half hours
of continuous teaching at the workplace. Maximum fundamental frequency
was an important acoustic parameter in determining presence of vocal
fatigue. Most common perceptual symptoms include throat dryness,
discomfort and loss of voice. The role of vocal hygiene and warm-up in

Abstract: One of the major causes of frequent voice disorders in teachers is
incorrect vocal emission technique. The aim of the study was to assess the
effect of logopedic training on voice emission parameters and vocal organ
disorders in students attending the college for teachers. The study group
comprised 45 female students who experienced vocal abnormalities after
excessive vocal effort. Questionnaire surveys, phoniatric and
videostroboscopic examinations were performed in all subjects before starting
and after completing the logopedic training. The training was preceded by a
theoretical seminar on voice organ anatomy, physiology, and hygiene. The
logopedic training lasting two-three months contributed to the improvement
in voice characteristics and the condition of voice organ in the majority of
students, as well as in phoniatric parameters, including the increase in the
maximum phonation time, the frequency range of voice, the reduction of the
glottal insufficiency and the elimination of "soft" vocal nodules. The results of
the study indicate that the implemented voice emission training improved
significantly voice quality and allowed for providing an efficient therapy of
already existing functional disorders of the larynx

survey of vocal health in young singers. J Voice 2002;16:244-250.
Ref ID: 138
Abstract: The objective of this study was to determine the incidence of vocal
problems in young choir singers and to correlate vocal problems with
demographic and behavioral information. A questionnaire addressing vocal
habits and hygiene was offered to 571 young choir singers, up to 25 years of
age, who sing at least weekly; 129 (22.6%) responded. More than one-half of
the respondents had experienced vocal difficulty, particularly older
adolescents. Detrimental behaviors and circumstances surveyed were not
reflective of the incidence of vocal difficulty, except for morning hoarseness,
chronic fatigue, insomnia, and female gender after puberty. Voice care
professionals should be aware that self-reported voice difficulties are common
among young choral singers, especially postpubescent girls, and children with
symptoms consistent with reflux (morning hoarseness) and emotional stress
(insomnia). Laryngologists should communicate with choral conductors and
singing teachers to enhance early identification and treatment of children with
voice complaints, and to develop choral educational strategies that help
decrease their incidence

Abstract: The medical literature contains relatively few examples of reports of
voice disorders that could be attributed to chemical exposure at work. General
medical conditions such as gastro-oesophageal reflux and the use of
medication such as inhaled steroids are well-recognized causes of laryngitis,
but the occupational causes are less well documented. This paper describes
the results of a literature review looking at the reporting of cases of
occupationally acquired voice disorders due to exposure to irritants in the
workplace
(229) Yiu E, Ma E. Voice activity limitation and participation restriction in the
teaching profession: The need for preventive voice care. J Med Speech Lang
Pathol 2002;10:51-60.
Ref ID: 425
Abstract: Teachers are prone to developing voice problems because of the
specific occupational demand of teaching. Voice problems impose difficulties
or limitations not only on their teaching activities but also on other daily voice
activities. Activity limitation and participation restriction are two separate
dimensions introduced in the International Classification of Impairments,
Disabilities, and Handicaps by the World Health Organization (1997). Teachers
with voice problems may face difficulties or limitations in their teaching
activities. However, they may have little choice but to continue participating in
these teaching activities. This study reports the extent of voice problems and
their impact on 30 self-selected teachers enrolled for a workshop to improve
their teaching voice. The findings show that job, daily communication, social
communication, and emotion were all affected in the majority of the teachers.
It also points to the need of implementing preventive voice care for the
teaching profession

singers and performing artists: treatment outcomes, management theories,
and future directions. Ann Otol Rhinol Laryngol Suppl 2002;190:21-40.
Ref ID: 128
Abstract: Phonomicrosurgery in performing artists has historically been
approached with great trepidation, and vocal outcome data are sparse. The
vocal liability of surgically disturbing the superficial lamina propria (SLP) and
epithelium must be balanced with the inherent detrimental vocal effect of the
lesion(s). A prospective investigation was performed on 185 performing
artists who underwent phonomicrosurgical resection of 365 lesions: 201
nodules, 71 polyps, 66 varices and ectasias, 13 cysts, 8 keratotic lesions, 2
granulomas, 2 Reinke's edema, and 2 papillomas. Nearly all patients with SLP
lesions reported improvement in their postsurgical vocal function. This
subjective result was supported by objective acoustic and aerodynamic
measures. All postsurgical objective vocal function measures fell within
normal limits, including a few that displayed presurgical abnormalities.
89
However, given the relative insensitivity of standard objective measures to
assess higher-level vocal performance-related factors, it is even more
noteworthy that 8 of 24 objective measures displayed statistically significant
postsurgical improvements in vocal function. Such changes in objective
measures mostly reflect overall enhancement in the efficiency of voice
production. Phonomicrosurgical resection of vocal fold lesions in performing
artists is enjoying an expanding role because of a variety of improvements in
diagnostic assessment, surgical instrumentation and techniques, and
specialized rehabilitation. Most of these lesions are the result of phonotrauma
and arise within the SLP. Successful management depends on prudent patient
selection and counseling, ultraprecise technique, and vigorqus vocal
rehabilitation. Furthermore, an understanding of the vocal function and
dysfunction of this high-performance population provides all otolaryngologists
who manage laryngeal problems with valuable information that they can
extrapolate for use in their practices

maintaining a high clinical index of suspicion. J Voice 2001;15:451-455.
Ref ID: 143
Abstract: Vocal fold mucosal tears have been discussed in the literature
rarely, although they are not uncommon clinically. Disruptions in the
epithelium usually follow trauma that may result from voice abuse and/or
misuse, coughing, and other causes. A high index of suspicion is necessary to
avoid missing vocal fold mucosal tears, and strobovideolaryngoscopy is
indispensable in making the diagnosis. A brief period of complete voice rest is
the standard of care and appears to be helpful in avoiding adverse sequelae
and advancing the healing process, but there are no scientific studies to
confirm its efficacy. Mucosal tears may heal completely or may be followed by
the development of vocal fold masses, scar, and permanent dysphonia
(237) King A, Ashby J, Nelson C. Effects of testosterone replacement on a male
professional singer. J Voice 2001;15:553-557.
Ref ID: 377
Abstract: Testosterone has been known to play an important role in the
development of the postpubertal male voice for many centuries. In fact, the
prevention of pubertal development of the voice by castrating young male
singers was a well-known practice, especially in Italy beginning in the
sixteenth century. The "castrati" were well known for their clear, high-pitched
voices. Because of the resulting small larynx and vocal folds, castrati
apparently produced a distinctive resonance as well as the high pitch, which
cannot be matched even by the counter tenors of today. Busy voice labs
occasionally see males with sex hormone deficiencies secondary to
chromosomal or gonadal problems. This is a presentation of an unusual
patient who was a trained tenor singer and was found to have hypogonadism
on a premarital health examination. Administration of replacement
testosterone resulted in significant vocal register and voice quality changes

Ref ID: 448
Abstract: OBJECTIVES: To assess the overall efficacy of voice therapy for
dysphonia. DESIGN: Single blind randomised controlled trial. SETTING:
Outpatient clinic in a teaching hospital. Participants: 204 outpatients aged 1787 with a primary symptom of persistent hoarseness for at least two months.
INTERVENTIONS: After baseline assessments, patients were randomised to
six weeks of either voice therapy or no treatment. Assessments were
repeated at six weeks on the 145 (71%) patients who continued to this stage
and at 12-14 weeks on the 133 (65%) patients who completed the study. The
assessments at the three time points for the 70 patients who completed
treatment and the 63 patients in the group given no treatment were
compared. MAIN OUTCOME MEASURES: Ratings of laryngeal features, Buffalo
voice profile, amplitude and pitch perturbation, voice profile questionnaire,
hospital anxiety and depression scale, clinical interview schedule, SF-36.
RESULTS: Voice therapy improved voice quality as assessed by rating by
patients (P=0.001) and rating by observer (P<0.001). The treatment effects
for these two outcomes were 4.1 (95% confidence interval 1.7 to 6.6) points
and 0.82 (0.50 to 1.13) points. Amplitude perturbation showed improvement
at six weeks (P=0.005) but not on completion of the study. Patients with
91
dysphonia had appreciable psychological distress and lower quality of life than
controls, but voice therapy had no significant impact on either of these
variables. CONCLUSION: Voice therapy is effective in improving voice quality
as assessed by self rated and observer rated methods

primary etiologic factor (part II). Med Pregl 2001;54:135-139.
Ref ID: 382
Abstract: INTRODUCTION: Phonation is a complex integral function of an
organism. Regular phonation is characterized by: clearness and adequate
pitch. Dysphonia is a disorder of phonation. It can have many acoustic forms,
but hoarseness is the best known symptom of dysphonia. Acoustic
phenomena in regard to voice are caused by: irregularities in vocal cord
vibration, turbulent airflow in the glottis and obstruction of glottis. PREVIOUS
CLASSIFICATIONS OF DYSPHONIAS: The best known classification of
dysphonias was introduced by Perello. There are two groups: 1. organic
dysphonias and 2. functional dysphonias. On the 8th Congress of the Union of
European Phoniatrists, in K÷szeg (Hungary, 1979), Majdevac proposed a new
classification. CLASSIFICATION OF DYSPHONIAS: We are proposing a new
classification according to the primary etiologic factor of dysphonias. In this
paper, we shall consider four gropus: from the fifth to eighth. V DYSPHONIAS
CAUSED BY PRIMARY ENDOCRINE DISORDERS: This group includes: 1.
Dysphonia caused by pituitary disorders 2. Dysphonia caused by thyroid gland
disorders 3. Dysphonia caused by parathyroid glands disorders 4. Dysphonia
caused by pancreatic function disorders 5. Dysphonia caused by suprarenal
function disorders 6. Dysphonias caused by sexual glands function disorders
7. Intersexuality. VI DYSPHONIAS CAUSED BY COMPLEX PROFESSIONAL
REASONS: This group includes: 1. Permanent hyperkinetic dysphonia 2.
Permanent hyperkinetic dysphonia with vocal cord nodules 3. Dysphonia
caused by myogenic imperfect closure of vocal cords 4. Phonastenia. VII
DYSPHONIAS CAUSED BY PRIMARY DISPLASTIC DISORDERS: This group
includes: 1. Dysphonia caused by laryngeal hypoplasia 2. Dysphonia caused
by laryngeal asymmetry 3. Dysphonia caused by epiglottal anomalies 4.
Dysphonia caused by laryngeal diaphragm. VIII DYSPHONIAS CAUSED BY
LARYNGEAL TUMORS: This group includes: 1. Dysphonia caused by benign
tumors 2. Dysphonia caused by malignant tumors. CONCLUSION: Dysphonia
is a disorder of phonation which originates from glottal level. Disorders of
phonation require observation of an organism as a whole and studying all
mechanisms which take part in voice production. This provides examination of
voice disorders, their establishment and adequate treatment

Abstract: The study aimed to assess whether a specific training program in
vocal and physical skills could reduce the level of perceived performance
anxiety. Eighteen undergraduate performing arts students were divided into
two even groups. The experimental group experienced 10 two-hour sessions
in a specialized vocal and physical skills training program. The control group
received the same number of sessions in text analysis by the same teacher.
Ten weeks after the training period, both groups were videotaped delivering a
short speech of general interest. The videotaped material was assessed by
four judges, using a visual analog scale (VAS). Perceptual variables
considered were eight vocal and physical features: physical ease, physical
presence, effective gesture use, effective eye contact, correct breath use,
suitable pace, vocal variety, speech clarity, and one performance feature:
perceived performance anxiety. Results indicated that the particular vocal and
physical skills training program used showed positive results in effectively
reducing the level of perceived performance anxiety. The experimental group
scored significantly higher on each of the eight vocal and physical features
and significantly lower on the perceived anxiety feature than the control
group. This research has implications for those affected by performance
anxiety in vocal presentation

Abstract: BACKGROUND: This is an update of a Cochrane Review first
published in The Cochrane Library in Issue 2, 2001 and previously updated in
2007.Vocal cord nodules are bilateral, benign, callous-like growths of the midportion of the membranous vocal folds. They are of variable size and are
characterised histologically by thickening of the epithelium with a variable
degree of inflammation in the underlying superficial lamina propria. They
characteristically produce hoarseness, discomfort and an unstable voice when
speaking or singing. OBJECTIVES: To assess the effectiveness of surgery
versus non-surgical interventions for vocal cord nodules. SEARCH STRATEGY:
We searched the Cochrane Ear, Nose and Throat Disorders Group Trials
Register; the Cochrane Central Register of Controlled Trials (CENTRAL);
PubMed; EMBASE; CINAHL; Web of Science; BIOSIS Previews; Cambridge
Scientific Abstracts; mRCT and additional sources for published and
unpublished trials. The date of the most recent search was 25 November
2009, following a previous update search in January 2007. SELECTION
CRITERIA: Randomised and quasi-randomised trials comparing any surgical
intervention for vocal cord nodules with non-surgical treatment or no
treatment. DATA COLLECTION AND ANALYSIS: No suitable trials were
identified. MAIN RESULTS: No studies fulfilled the inclusion criteria. AUTHORS'
CONCLUSIONS: There is a need for high quality randomised controlled trials
to evaluate the effectiveness of surgical and non-surgical treatment of vocal
cord nodules. SURGERY VERSUS NON-SURGICAL INTERVENTIONS (VOICE
THERAPY, MEDICAL TREATMENT) FOR THE RESOLUTION OF VOCAL CORD
NODULES: Vocal cord nodules are benign, callous-like growths on the vocal
93
cords. Symptoms include hoarseness, throat discomfort, pain and an unstable
voice when speaking or singing. They can be caused by 'voice abuse'
(prolonged shouting or singing above the individual's own range) but may
also be caused by infection, allergy or acid reflux.Vocal cord nodules can be
surgically removed but may also be treated with non-surgical voice therapy
interventions (e.g. voice re-training, rest or hygiene advice) or
medical/pharmacological treatment of underlying infections, allergy or
gastroesophageal reflux.The authors of this review sought to identify trials
which compared surgical with non-surgical treatment. They found that there
was not enough evidence to compare surgery to other treatment options.
More research is needed

Ref ID: 393
Abstract: Purpose of the study. To describe the system of recognition and
compensation of occupational diseases in the Czech Republic including its
advantages and weak points. Method. Statistical data concerning occupational
diseases in the Czech Republic are presented here. Czech criteria for
acknowledgement of occupational diseases and some advantages and
disadvantages of the Czech system are discussed. Results. In the Czech
Republic, 1 751 occupational diseases were acknowledged in the year 2000.
The Czech List of occupational diseases is divided into six chapters. Diseases
due to physical factors come first among statistical data with 39.9% in the
year 2000. Diseases of the respiratory system and skin diseases represent
20.7% each; infectious diseases, 16.4% of all occupational diseases.
Poisonings were acknowledged only in 2.1% and other diseases (i.e. disorders
of vocal cords) in 0.2% cases. Discussion The Czech system is simple.
Occupational medicine specialists play a crucial role. Working conditions and
exposures to noxious agents are controlled by the regional occupational
hygienists. If the conditions at work do not meet appropriate criteria,
occupational disease cannot be acknowledged. All diseases are compensated
according to the general system of the Social insurance. The compensation of
occupational diseases in the Czech Republic is relatively generous; therefore
the phenomenon of under-reporting is not very important. Rather frequently
the patients try to be acknowledged for an occupational disease in order to
solve their social, psychological and non-occupational problems. A
disadvantage of the Czech system is the insufficient promotion of the need for
prevention of these diseases. The taxes of the employers are not increased
with the increasing number of occupational diseases. Conclusion The
statistical data concerning occupational diseases strictly depend on the
criteria accepted in different countries. It is necessary to promote at the
European level the harmonization of the recognition and compensation of
occupational diseases in accordance with the demands of justice and equity.
Different criteria of recognition and acknowledgement of occupational
diseases in European countries make the comparison very difficult

of the effects of two treatment approaches for teachers with voice disorders:
a prospective randomized clinical trial. J Speech Lang Hear Res 2001;44:286296.
Ref ID: 149
Abstract: Teachers commonly report voice problems and often seek medical
assistance for voice-related complaints. Despite the prevalence of voice
disorders within this occupation, there are no studies evaluating the
effectiveness of treatment programs designed to remedy the voice problems
of teachers. To assess the functional effects of two voice therapy approaches,
58 voice-disordered teachers were randomly assigned to 1 of 3 groups: vocal
hygiene (VH, n = 20), vocal function exercises (VFE, n = 19), and a
nontreatment control group (CON, n = 19). Subjects completed the Voice
Handicap Index (VHI)-an instrument designed to appraise the self-perceived
psychosocial consequences of voice disorders-before and following a 6-week
treatment phase. The VFE and VH subjects also completed a posttreatment
questionnaire regarding the perceived benefits of treatment. Only the group
who adhered to the VFE regimen reported a significant reduction in mean VHI
scores (p <.0002). Furthermore, when compared to the VH group, the
exercise group reported more overall voice improvement (p < .05) and
greater ease (p < .02) and clarity (p < .01) in their speaking and singing
voice after treatment. These findings suggest that the VFE should be
considered as a useful alternative or adjunct to vocal hygiene programs in the
treatment of voice problems in teachers

disorders among day care center teachers compared with nurses: a
questionnaire and clinical study. J Voice 2001;15:413-423.
Ref ID: 144
Abstract: The acceptance of voice disorders by day care center teachers as an
occupational disease is not an invariably established practice. This is due to
the lack of reliable evidence of a higher risk for voice disorders in this
profession. To find out the risk of voice disorders, an epidemiological study
was conducted among day care center teachers (n = 262), using hospital
nurses (n = 108) as a control group. Symptoms were charted by a
questionnaire. In a clinical examination made by a laryngologist, the voice
quality was assessed and the laryngeal status noted. Teachers at day care
centers had significantly more voice disorders than did nurses. Vocal nodules
and laryngitis findings appeared significantly more frequently among day care
center teachers than among those in the control group. The results prove
voice disorders to be more frequent among day care center teachers than
among control group subjects, and also that the main cause for this may be a
higher vocal loading among day care center teachers than among control
group subjects

but especially crucial for voice professionals. Professional voice users include
not only singers and actors, but also clergy, teachers, receptionists, sales
personnel, physicians, and anyone else whose ability to earn a living is
impacted negatively by loss of vocal quality and endurance. Physicians should
be familiar with the latest concepts in voice diagnosis and treatment, and with
the management of common voice disorders

method that can be administered by the health care personnel in order to
select students for further examination by the speech language therapist
and/or phoniatrician. The screening method consists of a perceptual
assessment of voice quality and a questionnaire concerning vocal symptoms.
As criterion for further medical investigation and voice therapy, we selected a
score of 35 mm or above on a visual analogue scale assessing Grade, i.e.
overall grade of hoarseness and/or two or more weekly or more often
occurring vocal symptoms. The results showed that health care personnel
with some training in assessing voices using the questionnaire are competent
to perform a rough voice screening on students

perceptually by a speech therapist and those who had abnormal voice quality
or reported several vocal symptoms were referred to a clinical examination by
a laryngologist. The results showed that 20% of this population reported two
or more vocal symptoms during the previous year and that 19% had an
organic voice disorder. This reinforces the need for clinical evaluation of
students with vocal symptoms and more vocal training in the teacher
education programs

Abstract: Vocal disorders are very common occupation-related disease in
teachers. Their remarkable incidence might be associated with inappropriate
techniques of speech and poor vocal hygiene. The aim of this study was to
assess the function of vocal organ including voice emission technique in
persons starting their teaching occupation. The study group included 66
female students at Teaching College. Their were thoroughly interviewed and
subjected to laryngological, phoniatric and videostroboscopic examinations.
All subjects reported subjective symptoms after vocal effort. Hoarseness and
throat dryness were the most common. In the majority of students functional
vocal disorders were observed. In 30% of them insufficiency of glottis and in
four (6.1%) students soft vocal nodules were found. Signs and symptoms of
vocal diseases were more frequent in a subgroup of students exposed to
increased vocal effort during their professional education. The results indicate
that young teachers are not sufficiently prepared for increased vocal strain,
apparently associated with their profession. It is indeed necessary to
introduce preventive programs including special training of appropriate speech
technique, into the curricula of schools for teachers

Abstract: The etiology of vocal apparatus diseases in opera singers is due to
both specific features of their theatrical activity and conventions of opera
genre in particular. A hundred and twenty seven vocalists (soloists and
choristers) aged 23 to 70 years with service length of 3 to 40 years were
examined. Both the status of the vocal apparatus itself and comorbidity were
found to affect the occurrence of occupational diseases of the larynx. Of great
97
importance are the quality of vocal background of a singer, his/her age,
length of service, the even distribution of vocal load during a month and a
season, the volume of additional work (concert and pedagogical activities),
the correspondence of parts to his/her techniques and actor's capacities, and
living and social conditions. The pattern of vocal apparatus diseases also
depends on the type of a singer's voice and on the status of his/her nervous
system. This study-based recommendations for singers and theater managers
administrators reduced the incidence rates of laryngeal diseases in the
followed-up professional opera singers by 15-20%

singing. J Voice 1999;13:128-142.
Ref ID: 161
Abstract: This study was undertaken to better understand current regional
opinions regarding vocal fold nodules in adult singers. A questionnaire was
sent to 298 persons representing the 3 professional groups most involved
with the care of singers with vocal nodules: otolaryngologists, speech
pathologists, and teachers of singing. The questionnaire queried respondents
about their level of experience with this problem, and their beliefs about
causative factors, career impact, and optimum treatment. Responses within
and between groups were similar, with differences between groups primarily
in the magnitude of positive or negative responses, rather than in the polarity
of the responses. Prevailing opinions included: recognition of causative factors
in both singing and speaking voice practices, optimism about responsiveness
to appropriate treatment, enthusiasm for coordinated voice therapy and voice
training as first-line treatment, and acceptance of microsurgical management
as appropriate treatment if behavioral management fails

Ref ID: 159
Abstract: OBJECTIVE: Abnormalities in the mucosal lining of the vocal folds
may interfere with the normal vibratory patterns and result in vocal
limitations, especially for singers whose demands are great. A prospective,
longitudinal study was undertaken to investigate the incidence of laryngeal
abnormalities in asymptomatic singing students. METHODS: Sixty-five singing
students at the school of music underwent videostroboscopic evaluation and
completed a comprehensive questionnaire. Videos were rated by 3
experienced clinicians, and interrater reliability was calculated. Results were
correlated with demographic factors, background medical history, and singing
history. RESULTS: Five students (8.3%) exhibited early signs of benign vocal
fold lesions (2 with nodules and 3 with cysts). A high incidence of posterior
erythema (n = 44; 73.4%), suggesting possible reflux, was found.
CONCLUSIONS: A surprisingly high number of otherwise asymptomatic
singing students demonstrated abnormal laryngeal findings. Their relationship
with vocal performance will be addressed as well as implications for
preventative measures

Abstract: A vocal health questionnaire was administered to three groups of
professional singers and a "friendship-matched" group of nonsingers in
Melbourne, Australia. The responses of 79 opera, 57 musical theatre and 31
contemporary (excluding rock) singers and 86 nonsingers were analysed. The
questionnaire solicited information regarding biographical data speaking and
singing voice-use behaviours, and vocal health over the previous 12 months
in terms of experiences of vocal impairment, vocal disability, and handicap.
Significant differences between singers and nonsingers in the prevalence and
nature of voice problems were reported. Of the singers, 44% reported one or
more occurrences of a diagnosed vocal condition compared to 21% of
nonsingers and 69% of singers experienced vocal disability compared to only
41% of nonsingers, over the previous 12 months. In contrast, no significant
differences were found between the three different styles of singers in their
experience of vocal impairment, disability or handicap

of pitch, register, and singing mode: Radiographic observations of a female
singer. J Voice 1999;13:319-340.
Ref ID: 413
Abstract: This study investigates pitch control, register, and singing mode
related movements of the laryngo-pharyngeal structures by radiographic
methods. One trained female singer served as the subject. The results show
that singing voice production involves complex movements in the laryngeal
structures. Pitch related increase in the thyro-arytenoid distance (vocal fold
length) is nonlinear, slowing down as pitch rises. Similar observations have
been made earlier. At the highest pitches, a shortening of the distance can be
seen, suggesting the use of alternative pitch control mechanisms. The various
observations made support the existence of three registers in this trained
female singing voice. Open and covered modes of singing seemed to be
distinguishable on the basis of different amounts of tuner and outer forces
acting on the larynx. Therefore, caution must be exercised when generalizing
from the results

of voice disorders in teachers treated in the Phoniatric Laboratory of the

Ref ID: 160
Abstract: Analysis of voice disorders in 898 teachers was performed. In all
cases otolaryngologic, videostroboscopic and phoniatric examinations were
completed. There was prevalence of women at the age ranged from 46 to 56
years. Majority of morphologic changes included Reinkes oedema (120 cases),
chronic simple laryngitis (109 cases), vocal nodules (95 cases), chronic
hypertrophic laryngitis (70 cases) and laryngeal polyps (35 cases). In 175
cases vocal insufficiency of glottis and in 57 cases functional disorders were
99
diagnosed. In 131 cases no morphologic and functional changes were found.
In the group of teachers the incidence of vocal insufficiency was higher than
in control group. The analysis of the examined teachers revealed that
professional disease was confirmed in 33% of cases. Majority of them
included vocal nodules and chronic hypertrophic laryngitis
(264) Barnes PJ, Woolcock AJ. Difficult asthma. Eur Respir J 1998;12:1209-1218.
Ref ID: 341
Abstract: Asthma is usually easy to manage, but ~5% of patients are not
controlled even on high doses of inhaled corticosteroids. It is important to
assess these patients carefully in order to identify whether there are any
correctable factors that may contribute to their poor control. It is critical to
make a diagnosis of asthma and to exclude other airway diseases, particularly
chronic obstructive pulmonary disease (COPD), and vocal cord dysfunction
('pseudo-asthma') . Poor adherence to therapy, particularly inhaled
corticosteroids, is a common reason for a poor response. There may be
unidentified exacerbating factors, including unrecognized allergens,
occupational sensitizers, dietary additives, drugs, gastro-oesophageal reflux,
upper airway disease, or other systemic diseases, that need to be identified
and avoided or treated. Psychological factors may be important in some
patients, but it is difficult to know whether these are causal or secondary to
troublesome disease. Some patients have instability of their asthma, with
resistant nocturnal asthma, premenstrual exacerbations or chaotic and
unpredictable instability (brittle asthma). A few patients are completely
resistant to corticosteroids, but more patients are relatively resistant and
require relatively high doses of corticosteroids to control their symptoms
(steroid-dependent). Some patients develop progressive loss of lung function,
as in patients with COPD. Management of patients with difficult asthma should
be supervised by a respiratory specialist and should involve careful
assessment to confirm a diagnosis of asthma, identification and treatment of
exacerbating factors, particularly allergens, and recording of peak expiratory
flow patterns. A period of hospital admission may be the best way to assess
and manage these patients. Treatment involves optimizing corticosteroids
therapy, assessing additional controllers such as long- acting inhaled or
subcutaneous beta /sub 2/ -agonists or subcutaneous, theophylline and
antileukotrienes. In some patients, the use of immunosuppressive treatments
may reduce steroid requirements, although these treatments are rarely
effective and have side-effects. In the future, the nonsteroid antiinflammatory treatments now in development may be useful in these patients

Ref ID: 430
Abstract: There is an increasing need for studies of efficacy of behavior
readjustment therapy procedures in human communicative disorders. Legal,
social, scientific and professional considerations point up the need for more
careful documentation of the effects of treatment techniques used by
phoniatricians and speech-language pathologists. This study is conducted in
order to evaluate the efficacy of the accent method of voice therapy (AM).
The AM is one of the holistic approaches for behavior readjustment voice
therapy. It tackles collectively and simultaneously the various parameters of
voice such as pitch, loudness and timbre. The results of intervention utilizing
the AM in this clinical trial are assessed in a relatively controlled setup.
Patients with voice problems resulting from various etiologic vocal pathologies
are distributed randomly into two groups. Group 1 (G1) is given the full
aspect of the AM, that is, voice hygiene advice plus the accent exercises to
correct the faulty vocal technique (habit). Group 2 (G2) receives only voice
hygiene advice. The AM is administered in individual sessions 20 min each,
twice a week, while the voice hygiene advice counseling is given once a week.
The assessment of the vocal pathology is done following a diagnostic protocol
utilizing subjective as well as quasi-objective measures of evaluation. The
initial assessment presents the baseline (pretest) data for both groups. The
follow-up evaluations are done at mid intervention (mid-test), that is, 10
sessions for G1 and 5 sessions for G2, and at the termination of
intervention/therapy (post-test). The difference in improvement between G1
and G2 at the end of the observation was generally significant in favor of G1.
There were significant improvements in G1 in certain items specific for the
various etiologic categories. The improvement from pretest to mid-test to
post-test values followed a linear tendency. The significance of the results is
discussed and the conclusions are outlined and criticized

Ref ID: 433
Abstract: STUDY OBJECTIVE: To compare two methods of double-lumen
endobronchial tube placement for thoracic surgery and to identify factors that
provide a rational basis for placement method selection. DESIGN:
Prospective, randomized study. SETTING: Teaching hospital. PATIENTS: 58
ASA physical status II, III, and IV patients scheduled for surgical procedures
requiring elective left-sided endobronchial intubation. INTERVENTIONS:
Patients were assigned randomly to either a group in which the initial
placement method was the traditional approach of placing the endobronchial
tube through the larynx and then advanced blindly into the left mainstem
bronchus, or to a second group in which the left mainstem bronchus was
intubated under direct vision using the fiberoptic bronchoscope.
MEASUREMENTS AND MAIN RESULTS: Of the 32 patients who underwent the
traditional approach, primary success occurred in 27 patients and eventual
success in 30. In 27 patients undergoing the directed approach, primary
success occurred in 21 patients and eventual success in 25. Two patients in
each group required the alternative method. The blind approach took 88 (+/91) seconds and the directed approach took 181 (+/- 193) seconds (p =
0.029). Timing data were analyzed using analysis of variance with respect to
method and secretions and then t-tests as appropriate. Categorical data were
analyzed using the Kruskal-Wallis and Fisher's exact tests as appropriate. All
values are reported as means +/- SD. CONCLUSION: Both the blind and
directed approaches resulted in successful left mainstem placement of the
endobronchial tube in the majority of patients but either method may fail
when used alone. More time was required using the directed approach.
Operator experience with both methods will increase the likelihood of success.
The choice of the initial approach may be influenced by patient factors as well
as available equipment and personnel

Abstract: Minor structural alteration on larynx represent minor congenital
alterations which do not provoke great impact in voice quality, but may cause
dysphonia when associated with an increase in the vocal demand. Initially, the
authors briefly introduce a discussion of the main disorders and their
treatment, and then narrate the case of a 28 years old patient who presents
four minor structural alterations but remain assymptomatic until he starts
using his spoken voice professionally. From this moment on, he starts
developing compensatory functional disorders which lead him to look for
medical help, but do not make him stop using the voice-professionally for
approximately 12 hours a day. The voice quality shows improvement with
phonotherapy. Surgical treatment will be done in case there is no stability in
this improvement

Ref ID: 439
Abstract: OBJECTIVES: Compare the most commonly used types of
tracheoesophageal voice prostheses, Blom Singer and Provox. STUDY
DESIGN: Prospective study of 113 prostheses placed in 52 patients randomly
selected to receive Blom-Singer and Provox. METHODS: Postoperative voice
was recorded at 1 and 4 months after valve placement. Survival time of the
prosthesis and four objective voice parameters were analyzed. Eight judges
rated all recordings in a random order for six subjective voice parameters.
Subgroup analysis for primary versus secondary placements and type of
procedure was performed. In addition, patients were asked for their
subjective assessment. RESULTS: Overall, Blom-Singer and Provox prostheses
give very similar voice quality, lifetime, and patient satisfaction. Cleaning
management is somewhat better for Provox, but there is a trend toward
better overall voice quality for the Blom-Singer prosthesis. In subgroup
analysis secondarily placed prostheses score somewhat better than primary
placements, and patients with total laryngectomy have better voices than
patients with extended laryngectomy combined with partial pharyngectomy.
CONCLUSIONS: Given the equal and good results in terms of voice quality,
other factors (e.g., costs, surgery-related factors, maintenance, patient
preference) should be taken into account when deciding which type of
tracheoesophageal voice prosthesis to use

Abstract: Modern computers and their implementation have enabled the
development of software based on mathematical computations, which analyse
the parameters of voice signals in real time, as well as in the spectral and
capstral domains. A software system written on the basis of specific methods
and algorithms for pathological voice analysis allows the evaluation of: to D;
PPQ, APQ, D S, D DISS, HNR, DH and GQ. The system was tested (using the
vowel "a") on 900 workers at the Neftochim and Devnya chemical refineries in
Bulgaria, exposed to irritating gases (NOx, SOx, etc.). The analysis of the
studied parameters of the voice signal "a" showed significant changes in 137
workers, diagnosed after routine otolaryngological examination as the
following laryngeal pathology: 101 workers suffered from chronic laryngitis,
31 from inflammatory-reactive formations on the vocal folds and five from
laryngeal carcinoma. The non-invasive microcomputer system for the
quantitative analysis of hoarseness enabled the scanning of laryngeal
pathology in large populations of workers exposed to irritating gases in the
chemical industry

Occupational exposures and squamous cell carcinoma of the oral cavity,

Ref ID: 165
Abstract: OBJECTIVES: This community based case-referent study was
initiated to investigate aetiological factors for squamous cell carcinoma of the
upper gastrointestinal tract. METHODS: The study was based on all Swedish
men aged 40-79 living in two regions of Sweden during 1988-90. Within that
base, efforts were made to identify all incident cases of squamous cell
carcinoma of the oral cavity, oropharynx and hypopharynx, larynx, and
oesophagus. Referents were selected as a stratified (age, region) random
sample of the base. The response was 90% among cases and 85% among
referents. There were 545 cases and 641 referents in the final study group.
The study subjects were interviewed about several lifestyle factors and a life
history of occupations and work tasks. The exposure to 17 specific agents
were coded by an occupational hygienist. The relative risk (RR) of cancer was
calculated by logistic regression, standardising for age, geographical region,
and alcohol and tobacco consumption. RESULTS: Exposure to asbestos was
associated with an increased risk of laryngeal cancer, and a dose-response
relation was present. The RR was 1.8 (95% confidence interval (95% CI) 1.1
to 3.0) in the highest exposure group. More than eight years of exposure to
welding fumes was associated with an increased risk of pharyngeal cancer
(RR 2.3 (1.1 to 4.7)), and laryngeal cancer (RR 2.0 (1.0 to 3.7)). There were
indications of a dose-response for duration of exposure. Associations were
also found for high exposure to polycyclic aromatic hydrocarbons (PAHs) and
oesophageal cancer, RR 1.9 (1.1 to 3.2). Exposure to wood dust was
associated with a decreased risk of cancer at the studied sites.
CONCLUSIONS: Some of the present findings confirm known or suspected
associations--such as asbestos and laryngeal cancer. The study indicates that
welding may cause an increased risk of pharyngeal as well as laryngeal
cancer. The findings corroborate an association between exposure to PAHs
and oesophageal cancer

Abstract: A noninvasive pressure-flow technique was used to compare
laryngeal airway resistances in nine female classroom teachers with
symptoms of vocal fatigue and seven teachers without symptoms of vocal
fatigue. Data were collected two times per day on the Monday, Wednesday,
103
and Friday of a typical work-week. No significant between-group differences
were found, but two within-group differences were notable. Airflow in the
fatigued subjects decreased across the sampling period (p = .0009). In the
controls, air pressure increased across the sampling period (p = .021). These
findings suggest that both groups may have reacted to vocal demands during
the week by employing two different strategies to maintain habitual laryngeal
airway resistance: laryngeal adjustments alone or laryngeal adjustments plus
increased respiratory drive. The first strategy, employed by the fatigued
subjects, may have been less efficient, thereby provoking conditions
associated with their vocal fatigue

Abstract: Vocal cord dysfunction (VCD) is a poorly understood entity that is
often misdiagnosed as asthma. We report eleven cases of VCD in which there
was a temporal association between VCD onset and occupational or
environmental exposure. We conducted a case-control study to determine if
the characteristics of irritant-exposed VCD (IVCD) cases differed from nonexposed VCD controls. Chart review of VCD patients at the authors' institution
produced 11 cases that met IVCD case criteria. Thirty-three control VCD
subjects were selected by age matching. There were statistical differences
between the groups in ethnicity and chest discomfort. There were no
statistical differences between the groups for gender, tobacco, smoking
habits, symptoms, or pulmonary function parameters. Varied irritant
exposures were associated with IVCD. IVCD should be considered in patients
presenting with respiratory symptoms occurring after irritant exposures

Abstract: This study examined perceptual evaluations of classroom teachers,
acoustic measures of their voices ( fundamental frequency [F0], frequency
range [F0SD], % jitter, and % shimmer), and behavioral measures (rate,
dysfluencies, and episodes of vocal fry). This preliminary study attempted to
identify perceptual and acoustic measures that discriminate between effective
and less effective classroom teachers. Seven teachers were recorded on
audiotape while presenting a 10-12 minute lecture. Voice samples (N >
200) for each teacher were subjected to acoustic analysis. Audiotapes were
evaluated by listeners (N = 180), who scale-rated and used an adjective
checklist to determine teachers' overall effectiveness. A three-member team
evaluated global aspects of voice (e.g., use of pauses, inflections, contours,
and phrasing). Results indicated that frequency range, frequency variability,
rate, and number of dysfluencies appeared to correlate with perceptual
judgments of teaching effectiveness and specific adjective descriptors. F0, %
jitter, and % shimmer did not appear to be linked to perceptual judgments.
Individual case profiles were established and recommendations were made for
future empirical research involving larger samples of teachers

teachers: differences by gender and teaching characteristics. J Voice
1998;12:328-334.
Ref ID: 166
Abstract: This study describes the effects of teaching activities on voice
problems in male (n = 274) and female teachers (n = 280). Over 38% of the
teachers studied complained that teaching had an adverse impact on their
voice and 39% of those had cut back teaching activities as a result. Compared
to males, female teachers more frequently reported a voice problem (38% vs.
26%, p<.05), acute (p<.05), and chronic (p<.05) voice problems, six
specific voice symptoms, and five symptoms of physical discomfort. However,
there were no gender differences in the perception that a voice problem
adversely affected their current or future teaching career. For every type of
course taught, women had a higher probability of reporting voice problems
compared to men: odds ratio (OR) = 1.7-2.1. Compared with other courses,
the teaching of physical education also was associated with an increased risk
of developing a voice problem (OR = 3.7, 95% CI: 1.4-9.4) independent of
gender, age, hours/day, or years taught. This is the first study to show that in
the same occupation, females report a higher frequency of vocal symptoms
than males even when teaching characteristics and years employment are
similar

Ref ID: 467
Abstract: This study describes the frequency of reporting vocal problems
among a random sample of elementary and high school teachers (n = 554)
compared to individuals working in other occupations (n = 220). Teachers
were more likely to define themselves as ever having a voice problem (32%
versus. 1%, p < .05); having a tired, weak, or effortful voice (p < .05 each);
and having a higher frequency of symptoms of physical discomfort with
speaking (p < .05). They also were more likely to perceive that their voice
problem negatively affected current job performance (p < .05) and limited
options regarding change in work (p < .05). About 20% of teachers but only
4% of nonteachers had missed work due to their voice. These findings
suggest that teachers are at high-risk for disability from voice disorders and
that this health problem may have significant work-related and economic
effects

Abstract: The relationship between vocal fold strain and vocal pitch in singers
and nonsingers singing a rising pitch series has been indirectly investigated
by means of lateral radiographs. Nonsingers tend to exhibit more strain than
singers. To standardize the degree of strain, an index of strain per semitone is
proposed. The semitone strain indicates the average amount of strain per 1
105
semitone of pitch increase or decrease. The index has been shown to be
affected by several factors: gender, singing training, singing technique, voice
class, age, and status of muscle function. Observations suggest that similar
groups of individuals occupy different positions on the stress-strain curve,
indicated by their semitone strain values

strobovideolaryngoscopy: variability in healthy singers. J Voice 1997;11:104107.
Ref ID: 172
Abstract: Strobovideolaryngoscopy has proven essential to accurate diagnosis
of voice disorders. Clinical interpretation of stroboscopic images usually
follows a standard assessment protocol. Features analyzed typically include
symmetry of amplitude, symmetry of phase, regularity of periodicity,
amplitudes and wave forms of individual vocal folds, presence or absence of
adynamic segments, and other features. Speed and smoothness of abduction
and adduction are also assessed. In order for stroboscopic data to be used
meaningfully in a clinical setting, it is essential for the laryngologist to
recognize the range of normal variability of these parameters. This may be
particularly important when trying to establish diagnoses for subtle voice
disorders in professional voice users. This study investigates
strobovideolaryngoscopic findings in a population of normal professional
singers without voice complaints. "Abnormal" strobovideolaryngoscopic
findings occur in this asymptomatic population of "volunteers." These
abnormalities might have been misinterpreted as causing voice complaints if
seen for the first time when the singer sought medical care for a voice
problem. Physicians must be aware of the range of laryngeal behavior that
may be found among normal subjects and must be cautious when interpreting
strobovideolaryngoscopic findings. This study also highlights the importance
of obtaining "normal" baseline strobovideolaryngoscopic evaluations on
professional voice users. The review of strobovideolaryngoscopy performed
upon 65 healthy, asymptomatic professional singers revealed an incidence of
58% "abnormal" findings as six clinical entities

Abstract: Various modifiable toxic risk factors for cancer of the larynx were
evaluated in our geographic area in a retrospective epidemiological study of a
sample of 373 patients diagnosed as cancer of the larynx chosen randomly at
the La Fe Hospital of Valencia Spain over a 5-year period. A "z" test of the
contrast of proportions of the laryngeal cancer series studied and the results
of a National Health Survey showed significant differences between the two
study populations (p < 0.05). Compared with the National Health Survey,
smoking had an odds ratio (OR) of 72.21 (33.10 < OR < 166.31) (p <
0.05, Mantel-Haenszel test). The association between smoking and cancer of
the larynx increased with the dose. Alcohol consumption had an OR: 1.52
(1.09 < OR < 2.11) (p < 0.05, Mantel-Haenszel test). Smoking carried
a risk of 71.21 and had an etiological fraction of 98.61% (IC 95%: 65.17100%), thus representing 98.61% of all etiological factors. Control of smoking
could have prevented 65.17-100% of cases of cancer of the larynx (243 cases
in our series). Alcohol consumption had a risk of 0.52 and etiological fraction
of 34.21% (IC 95%: 2.38-100%). Control of alcohol use could have
prevented cancer of the larynx in 2.38-100% of cases (9 cases in our series)

to various extent, with more marked impairments in the central, rather than
in the peripheral part of the hearing system. It was shown, that hearing at 48 kHz, as well as with the extended frequency band, especially at 14-16 kHz,
time patterns of acoustic evoked potentials (latencies of waves III and V of
SLAEP, the interpeak interval I-V, as well as the latency periods of the LLAEP
components P2 and N2) could be useful in professional selection of individuals
of voice and speech professions and for solving labor expertise matters. Of
those individuals with normal voice but systematic vocal stress, 17.5% had
impaired hearing at 14 and 16 kHz, as well as significant latency prolongation
107
of the LLAEP wave N2 with tone stimulation at 1 and 4 kHz. Apparently,
individuals of voice and speech professions should be referred to as the "risk"
group. It may well be, that extended band audiometry and acoustic evoked
potentials time patterns could be useful in determining the thresholds
between the normality and pathology in voice dysfunctions

teachers' voice problems. J Voice 1997;11:81-87.
Ref ID: 173
Abstract: This study compared the frequency and effects of voice symptoms
in teachers to a group of individuals employed in other occupations. Teachers
were more likely to report having a voice problem (15 vs. 6%), having 10
specific voice symptoms, and having 5 symptoms of physical discomfort. They
averaged almost 2 symptoms compared with none for nonteachers. Likewise,
teachers were more likely to perceive that a voice problem would adversely
affect their future career options, had done so in the past, and was limiting
their current job performance. Over 20% of teachers but none of the
nonteachers had missed any days of work due to a voice problem. These
findings suggest that teaching is a high-risk occupation for voice disorders
and that this health problem may have significant work-related and economic
effects

incidence of cancer of the oral cavity, larynx, and oesophagus. Occup Environ

Ref ID: 171
Abstract: OBJECTIVES: To investigate whether employment in dry cleaning,
and potential exposure to perchloroethylene (PCE), were associated with
increased risk of carcinoma of the oral cavity and pharynx, larynx,
oesophagus, and gastric cardia. METHODS: Two population based casecontrol studies were carried out. There were 491 cases of carcinoma of the
oral cavity and pharynx, 235 of the larynx, and 404 of the oesophagus and
gastric cardia. 724 controls were selected by random digit dialing. Personal
interviews ascertained information on lifetime job histories, cigarette use,
alcohol consumption, and other potential risk factors. The probability and
level of exposure to PCE were estimated from the scientific literature.
RESULTS: People who worked in dry cleaning tended to consume less alcohol
and cigarettes than the general population. The adjusted odds ratio (OR)
associated with ever having worked in dry cleaning was 1.6 (95% confidence
interval (95% CI) = 0.6 to 4.4) for all cancer types together. The strongest
associations were with laryngeal (OR 2.7; 95% CI 0.6 to 10.9) and
oesophageal squamous cell carcinomas (OR 3.6; 95% CI 0.5 to 27.0). For
laryngeal cancer, the relative risk increased with number of years employed in
the dry cleaning industry (P = 0.14. The two cases of oesophageal squamous
cell carcinomas had worked in dry cleaning for only a short time. Analyses of
subsites showed higher risks for supraglottic laryngeal cancer (OR 5.7; 95%
CI 1.0 to 32.1) and cancer of the tongue (OR 2.3; 95% CI 0.4 to 12.6).
Analyses of exposure to PCE yielded similar results. CONCLUSIONS: These
findings could easily be explained by chance; nevertheless, they are
consistent with previous reports of excess risk of oesophageal, laryngeal, and
tongue cancer, and suggest that previous studies of dry cleaners that could
not control for alcohol and cigarette use may have underestimated the
relative risks of such cancers

Ref ID: 178
Abstract: Some singers with benign vocal fold mucosal lesions remain
unacceptably impaired vocally in spite of compliance with a regimen of
medical treatment and voice therapy lasting several months-or even years. I
present here my experience with 62 singers who, because of this
predicament, chose to undergo vocal fold microsurgery. This series is the
second largest reported to date in English literature. Procedures are
presented which were used for patient selection, education, and vocal
retraining, as well as for surgery itself and postoperative care. Results
reported here include (a) comparison of my auditory-perceptual ratings of
singing voice impairment before and after surgery, (b) preoperative versus
postoperative videostroboscopic findings, (c) postoperative rate of return to
public singing, and (d) postoperative patient questionaires which sought to
uncover patient/singer perceptions of the results of vocal fold surgery.
Excellent results were achieved overall with a very low incidence of untoward
results, and no complications were encountered

Ref ID: 353
Abstract: The larynx, as the passageway for air from the upper to the lower
respiratory tract, is exposed to all of the pollutants that reach the lungs.
However, the larynx seems much less susceptible to damage from these
contaminants. The major result is the development of carcinoma of the
larynx. A cause and effect relationship has been difficult to demonstrate.
Retrospective population studies are used to determine pollutant influences.
Most reports are from countries other than the United States, perhaps
because of industry concerns about litigation in that nation. One basic science
research report exposed guinea pig tracheas to varied concentrations of sulfur
dioxide and studied mucociliary activity using a modified light beam reflex
method. This may be a method to evaluate the effects of other pollutants on
the larynx

Ref ID: 445
Abstract: Several studies have examined the effects of patient characteristics
on force of laryngoscopy, but little attention has been paid to the importance
of technique and equipment. This study investigated whether force, torque,
head extension, and view varied significantly between laryngoscopists and
compared force and torque using Macintosh 3 and Miller 2 blades. The study
population consisted of ASA grade I and II patients requiring general
anesthesia and endotracheal intubation for elective surgery. Force, torque,
head extension, and laryngeal view were highly reproducible when
laryngoscopy was repeated by the same individual, Force and torque showed
great variation between laryngoscopies performed by different anesthetists,
For example, peak force varied over a range of 56 newtons among patients,
but could also vary as much as 30 newtons between different anesthetists
repeating laryngoscopy in the same patient. Force and head extension were
30% less with Miller laryngoscope compared to the Macintosh. Thus,
laryngoscopic force and torque depend on technique and equipment. Further
109
studies of force and torque may lead to improved techniques. The forcemeasuring laryngoscope could be a useful tool in teaching laryngoscopy

situ of the glottic larynx: excision or irradiation? Head & neck 1996;18:225228.
Ref ID: 452
Abstract: BACKGROUND: The management of glottic carcinoma in situ (CIS)
is controversial, with vocal cord stripping (S) generally accepted as the
standard treatment, and radiotherapy (RT) as an alternative. We present our
experience with 34 patients treated by either stripping or RT. METHODS: +
+Between 1974 and 1990, 34 patients with CIS of the glottic larynx larynx
were treated at McGill University teaching hospitals. The median age at
diagnosis was 67 years, with a male:female ratio of 6:1. All patients had CIS
involving the glottis and the pathology was reviewed on all patients. Twentyone patients were treated by S and 13 patients by RT as the primary
treatment. RESULTS: With a median follow-up of 96 months (25-209
months), the 15-year actuarial survival rate is 95% for all patients, with
100% and 87% survival rates for S and RT groups, respectively (p = 0.25).
One patient in the RT group developed a subglottic invasive squamous cell
carcinoma. On the other hand, 11 patients in the S group developed
recurrence and were treated by repeat S (6 patients) or RT (5 patients), with
a salvage rate of 100%. CONCLUSION: Although most patients with CIS of
the glottis are traditionally treated with vocal cord S, RT is effective in terms
of freedom from recurrence; it is an attractive option and should be
considered in patients with lesions recurring after stripping as well as in those
whose follow-up presents a problem
(293) Parnes S. Effects of asbestos on the larynx. Curr Opin Otolaryngol Head Neck
Surg 1996;4:54-58.
Ref ID: 392
Abstract: Asbestos, a naturally occurring hydrated silicate, may have a
detrimental influence on the larynx. Since this potential effect was first
recognized more than 20 years ago, multiple studies have sought to evaluate
it further. In a review of 33 cohort studies, the majority did not demonstrate
any increase in standard mortality rates and those that did often failed to take
into account the compounding effects of cigarette smoking and alcohol
consumption. Twenty-six case-control studies were also examined, and again
very few demonstrated that those patients who presented with laryngeal
cancer had had an increased exposure to asbestos. There also have been
three cross- sectional studies performing on-site head and neck examinations
where no specific laryngeal cancer had been seen in high-risk patients. The
on- site studies, however, did demonstrate a higher incidence of harmful
effects on the larynx, noting edema, inflammation, or specific lesions. Thus,
there is some support that asbestos may act as an irritant, although a causal
relationship between asbestos and laryngeal cancer cannot be definitively
established

Abstract: Macroscopic, cytologic and bacteriologic conditions of mucous
membranes of the upper airways in workers (n = 146) of the Polifarb Factory,
Wrocław, exposed to dusts and solvent vapours used in the paint and
varnish production was estimated. In 89% of the workers, pathologic changes
in throat mucous membranes were observed. Three types of macroscopic
changes were distinguished. In workers with the shortest period of
employment, laryngeal oedema congestion alteration was diagnosed, and
atrophic changes with medium intensity were observed in workers employed
for a long period. It was found that cytologic changes in the nose mucous
membrane depended on the duration of exposure. Inflammation cytograms
appeared during the first period of exposure to the substances discussed. The
longer period of exposure, the more clear features of metaplasia squamous
epithelium. The composition of the nose and throat bacterial flora changed
according to the length of employment. An increased growth of G(-) genera
Enterobacter, Klebsiella, Proteus, Escherichia and Candida fungi was found in
workers with long period of employment

Abstract: Reports of allergic laryngitis are sparse. In some reports allergy has
been mentioned as an aetiological factor, but the diagnosis has not been
confirmed with provocation tests. This paper reports on 20 patients in order
to show that laryngitis can be caused by organic substances and chemicals
with mechanisms of immediate allergy or immediate type specific
hypersensitivity. The agents in the former group consisted of flours, obeche,
plants and acid anhydrides, whereas these in the latter group included
chemicals like formaldehyde, acrylate compounds, and chemicals used in
hairdressing. All the cases were confirmed with provocation tests in which the
patients displayed a change in vocal cord status. Thirteen patients had
positive skin-prick test results with suspected causative agents. Eleven of
these 13 patients had an elevated level of specific IgE-antibodies to the same
agents

Ref ID: 432
Abstract: The speech characteristics of 29 patients with primary
tracheoesophageal puncture who received either a pharyngeal constrictor
myotomy, a unilateral pharyngeal plexus neurectomy, or a unilateral
pharyngeal plexus neurectomy with drainage myotomy limited to the
cricopharyngeus were studied. All patients used a Blom-Singer low-pressure
voice prosthesis. Audio recordings of each patient speaking with both the
Blom-Singer tracheostoma valve and manual occlusion of the tracheostoma
were recorded at 3 weeks, 6 months, and 12 months after surgery. The three
surgical variations were equally effective at preventing pharyngospasms; only
1 patient (10%) in each group had some loss of fluency during the 12-month
study period. Neurectomized patients produced significantly higher
fundamental frequencies during reading than did patients in the other groups.
Residual resting tone in the neurectomized pharyngoesophageal segment may
contribute to more favorable speaking frequencies in this group

methylphenidate for attention-deficit hyperactivity disorder in children with tic
disorder. Archives of general psychiatry 1995;52:444-455.
Ref ID: 441
Abstract: BACKGROUND: The findings from case reports and patient
questionnaire surveys have been interpreted as indicating that administration
of stimulants is ill-advised for the treatment of attention-deficit hyperactivity
disorder in children with tic disorder. METHODS: Thirty-four prepubertal
children with attention-deficit hyperactivity disorder and tic disorder received
placebo and three dosages of methylphenidate hydrochloride (0.1, 0.3, and
0.5 mg/kg) twice daily for 2 weeks each, under double-blind conditions.
Treatment effects were assessed using direct observations of child behavior in
a simulated (clinic-based) classroom and using rating scales completed by the
parents, teachers, and physician. RESULTS: Methylphenidate effectively
suppressed hyperactive, disruptive, and aggressive behavior. There was no
evidence that methylphenidate altered the severity of tic disorder, but it may
have a weak effect on the frequency of motor (increase) and vocal (decrease)
tics. CONCLUSION: Methylphenidate appears to be a safe and effective
treatment for attention-deficit hyperactivity disorder in the majority of
children with comorbid tic disorder

teachers of singing and control subjects. Journal of voice : official journal of

Ref ID: 450
Abstract: Using a questionnaire format, 125 teachers of singing and 49
control subjects indicated whether they had a current or past voice problem,
and provided information about their demographic characteristics, voice use
patterns, and medication use. The results revealed similar rates of current
voice problems reported by the two subject groups. However, teachers of
singing were considerably more likely to report ever having had a voice
problem than controls (64 vs. 33%). Risk factors were similar for the two
groups. Dehydrating medications and a report of a past voice problem both
increased the likelihood of perceiving a current problem, by a factor of three
and five, respectively. Females were twice as likely to report a past voice
problem as males, and younger subjects were slightly more likely to report a
past problem as compared with older subjects. The implications of the
findings are discussed from a theoretical as well as pragmatic perspective

Abstract: STUDY OBJECTIVE: To compare laryngoscopic appearance obtained
during flexible fiberoptic laryngoscopy with the patient's atlanto-occipital joint
in the neutral and extended positions. DESIGN: Controlled clinical trial with
each patient (in the neutral position) acting as his or her own control.
SETTING: University teaching hospital. PATIENTS: 20 adult ASA physical
status I and II patients, without anatomical airway abnormalities, undergoing
elective surgical procedures. INTERVENTIONS: Fiberoptic laryngoscopy was
performed on each patient with his or her atlanto-occipital joint in the neutral
and extended positions. MEASUREMENTS AND MAIN RESULTS: Photographs
of the laryngoscopic appearances were graded on a scale of 1 to 4 by a
blinded observer according to the proportion of the laryngeal inlet visible.
Atlanto-occipital extension improved laryngoscopic appearance in 14 cases
and produced no change in the remaining 6. CONCLUSION: Atlanto-occipital
extension is a useful maneuver during attempted fiberoptic intubation

double-blind placebo-controlled study with clonidine and desipramine.
Pediatrics 1995;95:74-81.
Ref ID: 466
Abstract: OBJECTIVES: Because psychostimulants can exacerbate preexisting
motor/phonic tics in individuals with Tourette's syndrome (TS), a clinical trial
was performed to examine the ability of clonidine and desipramine to modify
attention-deficit hyperactivity disorder (ADHD) behaviors in children with TS
+ ADHD. METHODS: A double-blind, placebo-controlled protocol was used in
which each subject served as his or her own control and received, in a
randomly assigned fashion, 6-week medication cycles with clonidine (0.05 mg
four times daily), desipramine (25 mg four times daily), and placebo.
RESULTS: Thirty-seven children with TS+ADHD between the ages 7 to 13
years and of normal intellect were recruited, and 34 (31 males, 3 females)
completed the entire protocol. Outcome measures for ADHD included Parent
and Teacher Child Behavior Checklists (CBCL), continuous performance tests,
and neuropsychologic tests of executive function. Several markers for ADHD
were shown to improve significantly (P < .05) after treatment with
desipramine (parent linear analogue rating, parent CBCL "hyperactivity"
113
subscale, and teacher CBCL subscales "nervous/overactive," "anxious," and
"unpopular"). Improvement with desipramine was always superior to that
noted with clonidine. Clinical improvement did not correlate with drug blood
levels. On measures of tic severity, neither drug made tics worse.
Desipramine showed a statistically significant improvement on a global linear
analogue scale, but not on the Hopkins Motor/Vocal Tic Severity Scale, the
Tourette Syndrome Severity Scale, or the Yale Global Tic Severity Scale.
Clonidine did not significantly alter tic severity on any measure.
CONCLUSION: The results of this study suggest that desipramine may be a
useful alternative for the treatment of symptoms of ADHD in children with TS

the larynx. In: Hinchcliffe R, Harrison D, eds. Scientific foundation of
otolaryngology. London: William Heinemann Medical Books, 1976:546-66)
mechanoreceptors in the subglottal mucosa play a significant role in the
control of laryngeal muscle activity in response to changes of subglottal
pressure during phonation. In singers this pressure is adapted not only to
phonatory loudness but also to fundamental frequency. By spraying Xylocaine
solution with a needle inserted into the trachea through the anterior gap
between the cricoid and thyroid cartilages, the subglottal mucosa was
anesthetized in three singers. The effects on subglottal pressure and
fundamental frequency of this anesthesia were examined. The pressure
effects varied between the subjects, whereas the fundamental frequency
accuracy was adversely affected in all three subjects. The implications of
these findings are discussed

attempted to practice vocal hygiene for 2 months. They showed significant
voice improvement as assessed instrumentally in terms of three acoustic and
electroglottographic parameters. There was no significant change of voice in a
control group of 13 teachers. The results suggest that teachers were able to
improve their voices if they significantly reduced vocal abuses in daily life and
practiced specific strategies to maintain classroom order and reduce the use
of voice in teaching

Ref ID: 186
Abstract: Since its introduction, the Sundberg model of the laryngeal system
as the resonance source of the singer's formant has gained wide acceptance.
However, no studies directly testing this hypothesis in vivo have previously
been reported. Thus, the present study was undertaken to test this
hypothesis on three classically trained professional male singers. The vocal
behaviors of the singer-subjects were evaluated during model and pulse
register phonation via magnetic resonance imaging, strobolaryngoscopy, and
acoustic analysis. Results indicated the subjects did not achieve the
laryngopharyngeal/laryngeal outlet cross-sectional area ratio requisite to the
model and that the formant remained robust in pulse register phonation. It
was concluded that these subjects' behaviors were not consistent with
Sundberg's model and that the model was inadequate to account for the
generation of the singer's formant in these three subjects

studies of machining fluid exposure in the automobile industry. III: A casecontrol study of larynx cancer. Am J Ind Med 1994;26:185-202.
Ref ID: 190
Abstract: A case-control study of larynx cancer was conducted within a cohort
of automobile workers exposed to metal working fluids, commonly referred to
as machining fluids (MF). Results are based on 108 cases of larynx cancer and
5:1 matched controls. Risks associated with specific types of MF, as well as
specific components of the fluids were evaluated. Based on a retrospective
exposure assessment, lifetime exposures to straight and soluble fluids,
grinding particulate, biocides, selected metals, sulfur, and chlorine were
examined. Exposure to asbestos and acid mists at two of the three study sites
was also characterized. Results suggest that straight mineral oils are
associated with almost a two-fold excess in larynx cancer risk. There was also
evidence of an association with elemental sulfur, commonly added to straight
MF to improve the integrity of the materials under extreme pressure and
heat. It is not clear whether sulfur is causally related to an excess relative risk
of larynx cancer or whether the observed association is the result of
unmeasured confounding by another contaminant or process feature. For
example, the high stress operations that require MF enriched with sulfur are
also more likely to produce polycyclic aromatic hydrocarbons (PAHs) during
the process. Thus, the observed association with sulfur may be due to an
association with PAH. The finding of excess risk of laryngeal cancer associated
with MF is consistent with several previous reports in the literature. This is the
first study, however, to distinguish straight mineral oils from other types of
115
MF. Based on these findings, a general reduction in concentrations of straight
mineral oil particulate in occupational environments would be prudent

Abstract: The efficacy and toxicity of two regimens of antimony, 28 and 40

culture-positive mucosal leishmaniasis involving more than one anatomic site.
Forty consecutive eligible Peruvians with infiltrative or ulcerative mucosal
disease of the lips, nose, palate-uvula-pharynx, or larynx-epiglottis were
randomized to receive either 28 days (P28) or 40 days (P40) of sodium
stibogluconate (Pentostam). Treatment was prematurely terminated due to
thrombocytopenia in three patients and two patients did not complete six
months of follow-up. At one month post-treatment, 13% (2 of 16) of the P28
patients and 16% (3 of 19) of the P40 patients no longer had infiltrates or
ulcers and were initially considered cured. During a further 11 months of
follow-up, infiltrated lesions healed in eight more P28 patients and in 10 more
P40 patients. The cure rate after 12 months of follow-up was therefore 63%
for both groups (10 of 16 in the P28 group and 12 of 19 in the P40 group).
The total of 13 patients who had infiltrates or ulcers at the 9-12-month
follow-up were considered failures. All seven patients (three in the P28 group
and four in the P40 group) whose lesions were culture-positive for Leishmania
at some point in the 12 months after treatment, and who were thereby
parasitologic failures, were also clinical failures.(ABSTRACT TRUNCATED AT

Ref ID: 189
Abstract: Performers (10 actors/10 singers) rated via a self-report
questionnaire the severity of their voice-related changes when vocally
fatigued. Similar frequency patterns and perceptual features of vocal fatigue
were found across subjects. Actors rated "power" aspects (e.g., voice
projection) and singers rated vocal dynamic aspects (e.g., pitch range) of
their voices as most affected when vocally fatigued. Vocal fatigue was
evidenced by changes in kinesthetic/proprioceptive sensations and vocal
dynamics. The causes and context of vocal fatigue were vocal misuse, being
"run down," high performance demands, and using high pitch/volume levels.
Further research is needed to delineate the perceptual features of "normal"
levels of vocal fatigue and its possible causes

Abstract: Cancer of the larynx is the most prevalent non-cutaneous
malignancy of the head neck region and its treatment presents a threat to
both natural speech and survival. This study examines the manner in which
two separate specialties in the same and different geographic regions vary in
their opinions about the treatment of glottic laryngeal cancer. The goal was to
define options available to patients and to classify controversies about optimal
treatment which might be resolved in clinical trials. Questionnaires depicting
different presentations of glottic larynx cancer were mailed to 1649
otolaryngologists and radiation oncologists in North America, Europe and
Australasia. Half the doctors were asked to describe their preferred treatment
for a patient while the others were asked to imagine that they themselves
were the patient. In all the disease situations opinions varied significantly with
respect to the treatment modality advised (whether to employ surgical or
radiotherapy approaches) and in more extensive disease situations the
intention of treatment also varied depending on whether a curative approach
should involve conservation or loss of the larynx. Doctors also recommended
similar treatment for their patients as they would for themselves. Apart from
disease extent the most significant variables influencing recommendations
were the physicians' specialty (P = 0.0001) and where they practice (P =
0.0001). These findings demonstrate diversity of opinion which is influenced
more profoundly by the traditions of the specialties and geographic location of
practice than by the reported results of treatments for laryngeal cancer.
Convictions about optimal management have become barriers to the

Ref ID: 191
Abstract: To control their voices, singers rely not only on auditory feedback
but also on proprioceptive feedback supplied by internal voice sensitivities
(IVS). IVS, which are essentially pallesthetic (vibratory) and kinesthetic
(muscular), provide singers with precise landmarks for controlling their
emission. This means of control is more reliable than auditory feedback in
which the voice is substantially modified by the acoustics of the environment

study of a professional singer. J Voice 1994;8:352-358.
Ref ID: 185
Abstract: A professional singer with laryngeal granuloma underwent surgery
following failed response to conservative treatments. Two primary findings
emerged. First, although a sizable lesion was present initially, presurgical
voice measures were largely normal or superior. The exception was elevated
phonatory effort during singing. Second, postsurgical voice functions were
entirely normal or superior (including phonatory effort), despite demanding
singing performances a few weeks following surgery. The results add to the
limited corpus of quantitative, normative-referenced data on voice in patients
with granulomas and are inconsistent with previous reports of voice
abnormalities in such patients and poor functional response to surgery

dysphonia after laryngeal surgery: a retrospective analysis of 62 patients.

Ref ID: 188
Abstract: Sixty-two patients with persistent or recurrent dysphonia after
117
laryngeal surgery underwent interdisciplinary voice evaluation,
laryngostroboscopy, and objective measurements of vocal function. The
causes of persistent dysphonia were attributed to vocal fold scarring (n = 22),
residual mass lesion (n = 8), residual inflammation (n = 13), recurrent mass
(n = 4), and hyperfunctional voice disorder (n = 7). Laryngoscopy often
showed excessive ventricular compression and anterior-to-posterior laryngeal
compression. Ventricular dysphonia was often a compensatory gesture in
response to poorly mobile vocal fold membranes. Stroboscopy was able to
document a number of abnormalities which included abnormalities of
laryngeal configuration, vibratory asymmetry, reduction of amplitude, and
mucosal wave. Using a diversified approach consisting of medical therapy,
voice therapy, and repeat surgery, better vocal function was able to be
restored in the majority of patients. An interdisciplinary approach to the
dysphonic patient after laryngeal surgery was most useful in defining the
pathology and refining a treatment rehabilitation program

Ref ID: 187
Abstract: Videography is the most practical and effective method of
documenting and teaching ENT endoscopy. Videography allows: (1)
documentation of anatomy, physiology and pathology of deep structures of
the ear, nose and throat; (2) teaching of delicate surgical procedures such as
functional endoscopic sinus surgery (FESS), laryngeal surgery, and other
endoscopic procedures; (3) instantaneous production of high quality hard
copies of video images for teaching and patient records; (4) instant replay
and repeated viewing by a slow motion or frame-by-frame analysis; (5)
simultaneous viewing by a small or large audience; and (6) image
digitalization for storage in the computer for later analysis. The author
describes the value of videography in ENT endoscopy, namely video-otoscopy,
video rhinoscopy and videolaryngoscopy. The use of video in endoscopy will
continue to play a vital role in Continuing Medical Education (CME)

and occupational risk factors in keratosis of the larynx]. Acta Otorhinolaryngol

Ref ID: 196
Abstract: Laryngeal keratosis may frequently precede the appearance of
carcinoma of the larynx which might well indicate that these diseases have a
common denominator. A retrospective study of 120 subjects with laryngeal
keratosis was examined. The intention of the Authors was to verify whether
the principle risk factors involved in the appearance of laryngeal carcinoma
were the same as those implicated in laryngeal keratosis formation. Sex age,
work activity, cigarette smoke, alcohol consumption and vocal chord abuse
were considered. Laryngeal keratosis takes keratosis with dysplasia as well as
keratosis without. A link between these two types of keratosis and cancer was
sought. In particular, the possibility that a persistent action of the mentioned
risk factors could cause laryngeal dysplasia-free keratosis to change into
dysplastic lesions and subsequently into cancer was investigated. A case-
control study was performed in order to analyze the importance of work
activity. Results were statistically significant (P < 0.001). The Cramer V2
calculation demonstrated a clear correlation between the number of cigarettes
smoked and the appearance of dysplasia (V2 = 0.117; P < 0.005). Results
showed a clearly different behaviour between sexes. The number of males
was much higher than females as was the age at which keratosis appeared
greater in males. The fact that the average age in which keratosis appeared
preceded the appearance of laryngeal cancer by ten years indicates that this
interrum is sufficient for keratosis with dysplasia to be transformed into
cancer (due to the continued action of the mentioned etiologic factors, mainly
referred to cigarette smoke). In our data analysis, no correlation was
demonstrated between keratosis without dysplasia and cancer

Ref ID: 194
Abstract: Recordings were made at the beginning and end of workdays of
teachers who experience vocal fatigue (n = 22) and those who do not
experience fatigue (n = 17). Those who experienced fatigue were recorded on
days in which they did and did not fatigue. Both groups evaluated their vocal
characteristics, each time they made a recording. Subsequently, a listener
panel evaluated the same characteristics from the recordings. Both groups
estimated the amount and characteristics of their talking time, completed a
psychological evaluation and provided medical histories. The authors interpret
the data obtained as indicating that the vocal characteristics of teachers who
fatigue and those who do not fatigue are similar on days the former group
does not fatigue and that the two groups are similar in the amount and
loudness of their talking time, at work and at home. However, teachers who
fatigue tend to spend more time in activities that appear to be vocally
demanding and are more likely to perceive situations as being anxiety
producing. Teachers who fatigue tend to be in good health, but have had
more hearing problems and allergies than their colleagues and more of their
family members have had voice problems

Abstract: Extensive investigations on the aerodynamics of inhalation show
that the laryngeal mucosa is an important target area for contact with
aerosols. These results, together with daily experience, point to the important
role of exogenous factors in laryngeal carcinogenesis. We have to examine
the probability of an occupational or nonoccupational cause or contributory
cause of the larynx carcinoma in the individual case. This paper presents
assessment criteria which, if applied consistently, permit a systematic
evaluation of this question. We warn against schematic use of yes-no
decisions and recommend weighting of various parameters (e.g., intensity
and duration of exposure, carcinogen combinations, cigarette smoking, and
occupational exposure)

Fluctuations in Phonation Time and Intensity in 4 Groups of Speakers. 1993.
Ref ID: 490
Abstract: Speech intensity and phonation time were measured in 11 office
119
workers, six kindergarten teachers, seven elementary school teachers, and
five patients with vocal fold nodules. Of the five patients, two were
elementary school teachers, two were office workers, and one was a
housewife. A speech intensity/speech time accumulator was used. A contact
microphone was attached to the neck of the subject to eliminate the influence
of environmental noise. Data were obtained by accumulating the phonation
time at four degrees of vocal intensity, ranging from weak to strong. By using
this instrument, the speaking habits of the 29 subjects were measured for up
to 12 days. Data were collected which were relevant for developing criteria for
vocal abuse. The findings indicated that workers in an office exhibited a
phonation time three times shorter than that of teachers and patients with
vocal fold nodules. For the teachers and patients with a long phonation time,
half of the total phonation time was at high intensity. In comparing two
typical cases, a kindergarten teacher and a patient with vocal fold nodules, it
was determined that the kindergarten teacher used extremely loud voice in
the range of 80 decibels and above only during her school time. The patient
used a loud voice by habit all the time. The authors suggest that it is
important to determine when and for how long the patient speaks loudly so
that the voice therapist can more adequately treat the patient

Abstract: In the winter semester 1991/92 and the summer semester 1992
60,6% of the students who are studying for teacher's profession at the
university of Essen have defects of speech. The study of the seminar for
speech education shows that logopedical therapies are necessary. The defects
most frequently observed were the different kinds of lisping and of
dysphonias. The observed differences of the german articulation standards
and the habituel abuse of voice must be treated, because teacher's profession
is a speaking profession and the teachers have to teach the german language
correctly concerning the orthographics and the orthoepics. The dysphonias
must be regarded as an occupation disease of teacher. Deficits in the offered
trainings at the university are the method of speaking and the formation of
the voice which must be trained prophylacticly. There is no departement of
speech at the university of Essen, only some invitations to lecture on the
subjects of speech. That's not sufficient as the study proved. We have to think
about the situation studying for teacher's profession and also about the
standards of articulation. There are a lot of problems concerning the speech
education that have to be discussed

Abstract: A survey questionnaire, designed in part to assess prevalence and
impact of vocal attrition, was administered to school teachers in different
locations across the USA. Analysis of 237 questionnaires obtained from
female teachers suggests that vocal attrition may be prevalent among
teachers. The mean number of symptoms of vocal attrition reported by the
teachers was 3.8. Over one half of the teachers reported multiple (3+)
symptoms. A significant number of teachers, especially those with multiple
symptoms, reported that their symptoms adversely affected their ability to
teach effectively and that their voice was a chronic source of stress or
frustration. The implications of these and other findings are discussed

in adults. The Annals of otology, rhinology, and laryngology 1993;102:209214.
Ref ID: 462
Abstract: Moraxella catarrhalis and Hemophilus influenzae are isolated from
the nasopharynx in 50% to 55% and 8% to 15%, respectively, of cases of
acute laryngitis in adults. This finding indicates that these organisms, M
catarrhalis in particular, are in some way involved in the pathogenesis of the
disorder. In the present double-blind, placebo-controlled trial, the effect of
erythromycin ethylsuccinate (0.5 g twice a day for 5 days) on the elimination
of nasopharyngeal pathogens and reduction of clinical signs of upper
respiratory tract infection, as well as on subjective complaints, was evaluated
in 106 adults with acute laryngitis. The bacterial isolation rates at
presentation were M catarrhalis 50%, H influenzae 18%, and Streptococcus
pneumoniae 4%. In the 99 patients who completed the study, the elimination
of M catarrhalis after 1 week was better in the erythromycin group (25 of 30
cases) than in the placebo group (6 of 19 cases; p < or = .00038). The
elimination of H influenzae was unaffected by erythromycin. Otolaryngologic
examination did not reveal any significant group differences regarding
laryngitis, pharyngitis, or rhinitis. Voice quality was improved after 1 week,
irrespective of treatment. However, as compared to the placebo group, the
erythromycin group reported fewer voice complaints after 1 week and fewer
coughing complaints after 2 weeks. As acute laryngitis in adults is selflimiting, and subjective symptoms are spontaneously reduced after 1 week in
most cases, antibiotic treatment does not seem warranted as a general policy.
However, erythromycin may be justified in patients who are professionally
dependent on voice function

Abstract: A case-control study has been used to analyse risk factors such as

natives and 130 immigrants) and 942 controls (557 and 385 respectively).
Tobacco smoking and exposure to air pollution in the place of work is
connected with increased incidence of larynx cancer risk among natives and
immigrants. It was shown that there is no connection between larynx cancer
and the degree of air pollution in the living place among natives

Abstract: Respiratory tract cancers, unlike most other cancers, have known
causes and are susceptible to primary prevention. According to a large
population-based case-control study in Southern Europe, over 90% of the
present incidence of laryngeal cancer could be prevented by avoiding smoking
and alcohol consumption. Most of the risk is attributable to tobacco, but
reducing alcohol alone could still prevent a quarter of the cases. Tobacco
121
smoking, on the other hand, explains 80 to 90% of lung cancer incidence in
Italy. Other known causal factors include: occupational exposures, which,
according to several studies, may account for one third of the cases in the
highly industrialized areas of Northern Italy; environmental pollution; passive
smoking; radon; and dietary factors. Factors associated to a diet rich in fruit
and vegetables have been found to be protective for both larynx and lung
cancer in several studies carried out in Italy and elsewhere. The factors
associated to this diet may be a major determinant in the North/South
gradient in incidence and mortality consistently observed in geographical and
migrant studies on respiratory cancers in Italy. Cigarette smoking, however,
remains by far the most important cause of respiratory cancer, and
geographical and temporal trends in incidence can easily be interpreted in
terms of market trends, both in Italy and worldwide. According to several
population surveys in Italy, the prevalence of smokers in successive male
cohort generations reached a maximum (almost 80%) in the 1920-1930 birth
cohorts and decreased to about 60% among males born in the forties and
fifties. In the same period, the mean number of cigarettes per day for
smokers increased, and the age of starting smoking decreased; however, the
market changed from unfiltered black tobacco to filtered low-tar cigarettes.
This market trend is consistent with the observation of decreasing incidence
and mortality of both larynx and lung cancer in young male cohorts and the
persistent increase of both cancers in older males. As for women, the
prevalence of smokers increased from less than 10% in the 1920's birth
cohorts to over 30% among women born in the late forties. This is reflected
by a steady increase of respiratory cancers mortality which, however, is still
lower than the mortality for males

Abstract: Squamous cell carcinoma of the larynx is a multifactorial disease. It
is firmly linked to several environmental risk factors. In the meanwhile, a
considerable amount of epidemiologic evidence has been built up to implicate
chronic consumption of alcohol and tobacco, occupation, diet, and social
status in the etiology of the laryngeal cancer. Herein is a report from the first
case-control study on the role of these risk factors conducted in a German

Abstract: We have performed a medialization laryngoplasty on a

has been slow to gain acceptance but offers many advantages over Teflon
injection because it is a reversible procedure and can be utilized early in vocal
cord paralysis instead of waiting 9 months. Postoperatively, the patient can
vocalize more than two octaves with good volume. Objective measurement of
results is needed in judging the success of these procedures

Abstract: Pollution is responsible for the presence of toxic substances and
conditions throughout our environment. Inhalation of toxic pollutants may
affect the voice adversely by direct laryngeal injury, by causing pulmonary
dysfunction that results in voice maladies, or through impairments elsewhere
in the vocal tract. Ingested substances- especially those that have
neurolaryngologic effects-may also adversely affect the voice. Non-chemical
environmental pollutants such as noise may also be responsible for voice
abnormalities. Most of the information about the effects of pollution on the
voice is anecdotal. Equipment and techniques that permit valid, reliable voice
research have recently become available; and studies on the impact of
pollution on communication, and specifically on voice, should be encouraged

Abstract: STUDY OBJECTIVE: To develop an approach to blind oral intubation.
With the aid of a fiberoptic laryngoscope and stylet within an endotracheal
tube, a video camera, a monitor, and a recorder to correlate the effects of
various manipulations of the airway on access to the trachea, a suitable
approach was devised. We then evaluated its efficacy. DESIGN: Randomized,
prospective comparison of regimens. SETTING: Inpatient surgery at a
university-affiliated teaching hospital. PATIENTS: One hundred adult patients
with no known abnormalities of the upper airway by history or on physical
123
examination, scheduled to undergo elective surgery, and without evidence of
major cardiac disease or need for a rapid-sequence induction of anesthesia.
INTERVENTIONS: Fifty patients in each of two groups were given fentanyl 5
micrograms/kg intravenously (IV), followed 2 minutes later by thiopental
sodium 5 mg/kg and succinylcholine 2 mg/kg. Patients in Group 1 (the
controls) were orally intubated via direct laryngoscopy using a Macintosh #3
blade. Patients in Group 2 (the experimentals) were intubated orally with the
approach developed without the use of a laryngoscope. Intubations were
deemed successful if they were performed within 1 minute after the mouth
was opened. MEASUREMENTS AND MAIN RESULTS: All the patients in Group
1 were successfully intubated within 1 minute, while 49 of the 50 patients in
Group 2 were successfully intubated within 1 minute. CONCLUSIONS: Blind
oral tracheal intubation can be successfully performed in a safe and effective
manner after appropriate teaching of the technique

Ref ID: 203
Abstract: A hospital-based case-control study of laryngeal cancer was
conducted in Bremen in 1986 and 1987 with 100 prevalent male laryngeal
cancer patients and 100 male hospital controls with diseases not considered
to be related to smoking, alcohol, or occupational exposures, who were
frequency matched by age. The odds ratio for heavy smoking (more than 30
pack-years) reached a value of 3.5 (95% confidence limits (CL) 1.1, 7.9). Exsmokers showed a significant decrease in risk; this reached the level of those
who had never smoked about 15 years after smoking cessation. For daily
consumers of alcohol an odds ratio of 3.2 (95% CL 1.4, 7.5) was observed.
Among the 17 occupations in which at least ten subjects had worked, excess
risks were observed for stock keeping and transportation workers, and for
leather and textile workers. The odds ratio was significantly increased for the
latter (p less than 0.05). Among all those persons ever employed in a priori
defined-risk occupations, an odds ratio of 2.74 (95% CL 1.23, 6.06) was
observed. Considering responses to an exposure check-list, no increased risks
could be shown for exposure to asbestos, coal tar, or welding fumes. On the
other hand, excess risks were observed for exposures to diesel oil, gasoline,
and mineral oil, controlling for smoking and alcohol. The findings in
occupational and exposure subgroups were based on small numbers of cases
and controls and, consequently, were subject to large sampling errors. Many
of the results are consistent, however, with occupational risk factors reported
from other studies

in functional dysphonia]. Laryngorhinootologie 1991;70:362-366.
Ref ID: 201
Abstract: A total of 160 voice-trained and untrained subjects with functional
dysphonia were given a "clinical rating" according to their clinical findings.
This was a certain value on a scale that recorded the degree of functional
voice disorder ranging from a marked hypofunction to an extreme
hyperfunction. The phonetograms of these patients were approximated by
ellipses, whereby the definition and quantitative recording of several
phonetogram parameters were rendered possible. By means of a linear
combination of phonetogram parameters, a "calculated assessment" was
obtained for each patient that was expected to tally with the "clinical rating".
This paper demonstrates that a graduation of the dysphonic clinical picture
with regard to the presence of hypofunctional or hyperfunctional components
is possible via computerised phonetogram evaluation. In this case, the
"calculated assessments" for both male and female singers and non-singers
must be computed using different linear combinations. The method can be
introduced as a supplementary diagnostic procedure in the diagnosis of
functional dysphonia

Abstract: The medical needs of professional voice users particularly singers
were evaluated. The anatomy of structures involved in voice production (the
larynx, supraglottic vocal tract, tracheobronchial tree, lungs and thorax) was
described. Contribution of the abdominal musculoskeletal system and
psychoneurological system was also considered. Aspects of medical history
taking from patients with voice problems and the effects of age on the voice
were examined. Common voice symptoms were discussed as were factors to
be considered when choosing a treatment plan. The latter included the date of
the next performance, the singing status and goals of the patient, the amount
and nature of the vocal training, and the type of singing environment. A
discussion of the effects of endocrine dysfunctions, mucosal irritants, diet and
previous laryngeal surgery on the voice was presented. Methods for physical
examination and objective analyses of voice patients were described.
Common diagnoses included: reflux laryngitis, anxiety, muscle problems,
voice abuse, vocal nodules, cysts and polyps, upper respiratory tract
infection, tonsillitis, and laryngitis. The treatment of such problems with
drugs, therapy, or surgery was discussed

Abstract: Spain is one of the countries with the highest incidence of laryngeal
cancer and, together with France, is the country with the lowest percentage of
women with this disease. In order to identify the occupational risk factors
associated with laryngeal cancer in this country a case-control study was
performed. Cases included 85 patients with epidermoid carcinoma of the
125
larynx diagnosed in "La Paz" Hospital, Madrid, between 1985 and 1987. A
sample of 170 patients from the same hospital was used as control. The
results of the study revealed that 56.5% of larynx cancer patients had a
sedentary occupation working in the service sector. Exposure to insecticides
or silica were strongest risk factors for laryngeal cancer. An association
between laryngeal cancer and exposure to fumes, chemical products, mineral
dust, or wood dust was not found

Ref ID: 207
Abstract: The significance of tobacco smoking, alcohol consumption and
occupation as risk factors for the development of vocal chord dysplasia was
evaluated in a case-control study. Twenty-seven male patients with dysplasia
of the vocal chords were chosen from the I. ENT-University Clinic in Vienna
(1985-1988) and compared with 54 controls. The main results are: The
relative risk (RR) of a smoker compared to that of a non-smoker for vocal
chord dysplasia is 7.27 (6.81-7.73); the RR adjusted for occupation is 3.58
(2.31-4.84). The most important risk factor, however, is occupational
exposure. The relative risk of a blue collar worker compared to that of a white
collar worker is 11.04 (10.61-11.46), which is reduced only to 10.02 (10.6111.46) after stratification according to smoking habits

Abstract: There is increasing evidence of an association between occupational
factors and head and neck cancer. The present paper reviews the most

these studies indicate an increased cancer risk for "blue collar workers"
exposed to dust or inhaled organic and inorganic agents. Moreover, the
increased risk of head and neck cancer in most studies persists after
adjustment for alcohol and tobacco consumption. More detailed, clinically
orientated studies are necessary to provide a better understanding of the role
of occupational factors in head and neck cancer

Abstract: A head and neck examination was conducted on 322 personnel in a
plant that manufactures brake linings and disks where asbestos is a major
component. The personnel were categorized according to occupational risk,
duration of employment, and smoking and alcohol habits. Thirty-nine percent
had abnormalities, the most common being laryngitis (15%), deviated nasal
septum (13%), and neck mass (5.3%). Six members required a biopsy, but
no cancer was discovered. Of 47 personnel with laryngitis, 46 were smokers
(P less than .01). In regard to asbestos exposure, 20% of the high-risk group
had laryngitis, compared to 11% in the low-risk group (P less than .05). The
data were compared to a previously prepared longitudinal study of plant
personnel (2057 individuals and 37,361.5 person years), where three cases of
laryngeal cancer had been observed (0.77 expected). As these cases involved
smokers with limited asbestos exposure, neither the longitudinal or crosssectional data could support asbestos as an etiologic factor for laryngeal
cancer, but it may act as an irritant

Abstract: As regards to 24 singers under observation traited for dysody (14
lyric singers, 3 amateur chorus singers and 7 pop singers), one deduces the
following points: almost all the singers traited are professional. The lyric
professional singers seek medical advice for minor lesions or simple
dysfunctions, as early as needed. In the classical amateurism, patients are
not adequately inform about the risk of vocal strain. They seek medical advice
for secondary lesions. The first two groups are treated with good results. The
majority of pop singers consult medical practitians, for surgical lesions. The
results of such treatments are frail

relationship with duration of exposure. In plant B, the odds ratios were low for

Abstract: The AA. have scheduled a case-control study in order to assess the
ambient hazards factors in these cancers, through the evaluation of its

of 322 (after the age) admitted at the same Hospital, but affected with
several processes. Were excluded the cancer of the lung, bladder, pancreas
and kidney because of the causal link with tobacco smokers. In oral and
pharyngeal cancer the AA. found out that the workers of high risk were
butchers, blacksmiths, masons, drivers, electricians and railwaymen.
Regarding the cancer of the larynx mechanics, plumbers, farmers, textile
workers and drivers showed the greatest linkage. These findings are in
accordance with those published in previous papers

Ref ID: 215
Abstract: Literature on functional voice disorders, on their etiopathogenetic
criteria linked in a complex way, on the multifaceted aspects of the
symptoms, and on the varieties, which arise out of influences during the longterm course of the disease has reached a considerable volume. In relation to
this fact, the description of therapeutic methods is thin and there is only
sparse attention given to quantitative facts, such as intensity and duration of
therapy and the possible influences of patients' professional field on the
therapeutic course. However, there is general agreement that qualitative
features and quantitative volume of therapy should be enlarged under the
holistic aspect of an adequate therapy of voice function, depending on
individual necessities. Under such a holistic aspect, two fundamental ways of
therapy are possible and both ways have advantages and disadvantages,
which originate from principal differences: out-patient therapy and in-patient
therapy. The Hamburg-Concepts of out-patient therapy of professional voice
disorders which were created, tested, corrected and in a long-lasting process
finally structured in terms of operational diagrams are discussed in this paper
under different points of view: the precondition is a complete evaluation of all
influencing factors in an interdisciplinary process. In closing, a new program
of cooperation between the institution for in-patient voice therapy in
Werscherberg/Osnabruck and the Hamburg Team is mentioned, a program
which, though very complex and risky, is intended to close the gap between
in-patient and out-patient therapy

Abstract: This paper presents the results of examinations of 522 workers
exposed to various industrial dusts and 361 workers exposed to different
concentrations of carcinogenic asbestos dust. The examinations showed a
significantly higher incidence of total processes in the upper respiratory tract
which manifested as chronic subatrophic nasopharingitis and hyperplastic
laryngitis. Also, they demonstrated a significantly higher incidence of local
processes that manifested as hyperplasia of the laryngeal mucosa and contact
fibromas. These laryngeal lesions can be viewed as etiologically associated
with the effect of industrial dusts having traumatic (abrasive and glass dust)
and carcinogenic (asbestos) properties. Patients with the above laryngeal
pathologies should be removed from the dust environment and sent to
physical examinations with emphasis on occupational diseases

(355) Vocal Cord Hemorrhages in Voice Professionals. Por buscar 1988.
Ref ID: 510
Abstract: Fourteen cases of vocal cord hemorrhage in professional voice users
were discussed. Two females had cases of bilateral hemorrhage and ten
females and two males had cases of unilateral hemorrhage. The patients with
bilateral hemorrhage complained of aphonia. The major complaints of the
patients with unilateral hemorrhage were hoarseness, loss of power, and
decreased vocal range. Three patients smoked 10 to 20 cigarettes daily. The
hemorrhages were induced by vocal trauma such as yelling, coughing, and
voice abuse and resulted from blood accumulating under the epithelium of the
vocal cords and edema in Reinke's space. The patients were examined by
indirect laryngoscopy, videostrobofiberoscopy, electrolaryngography, or
computed tomography. The bilateral hemorrhage patients recovered their
voices completely 3 months after treatment (not specified) and voice rest
were initiated. The patients with unilateral hemorrhage were treated with
cortisone for 3 days, antibiotics for 8 days, antiinflammatory agents for 12
days, and vocal rest for 2 weeks. Three patients recovered full voice function
within 1 month. Nine required surgery to remove the hematomas and their
sequelae 5 weeks to 6 months after diagnosis. The surgery was done by a
carbon-dioxide laser in conjunction with endoscopy under general anesthesia.
All surgery patients recovered their voices and were able to continue their
careers. The author suggests that surgery should be a component of therapy
for vocal fold hemorrhages

Ref ID: 493
Abstract: The occurrence of laryngeal pathologies and their distribution across
the variables of sex, age, and occupation were described. A total of 1,262
patients seen in six separate otolaryngologic practices was studied
retrospectively, using the medical charts of all patients with laryngeal
pathology seen over a 3 year period. Twenty two different laryngeal
pathologies were identified, with nodules, edema, polyps, cancer, vocal fold
paralysis, and dysphonia being the most common, in that order. Pathologies
were significantly more common in females than in males. Of the cases of
psychogenic disorders, 29/34 occurred in females. Cancer, leukoplakia, and
hyperkeratosis occurred significantly more often in males. The pathologies
occurred primarily in the older age brackets. Fifty seven percent of patients
were over 45 years old. Nodules and edema were most common in early
adulthood, polyps and dysphonia with a normal larynx in middle adulthood,
and vocal fold paralysis in late adulthood. The ten most frequently occurring
occupations were retired persons, homemakers, factory workers, unemployed
persons, executives and managers, teachers, students, secretaries, singers,
and nurses

clinical features in both sexes were muscle tension in the neck, poor control of

men sounded like Humphrey Bogart and the women like Lauren Bacall. These
cases represent a discrete clinical vocal fatigue syndrome, the treatment of
which is patient education and voice therapy

Abstract: We report two cases of recurrent episodes of hoarseness, cough,
flushing, pruritus, and rash occurring within 30 minutes of topical exposure to

was performed and plasma histamine levels were obtained prior to and 30
minutes after cutaneous challenge of a patient with alkylphenol novolac resin.
We documented marked laryngeal edema and a sixfold increase in plasma
histamine levels after challenge. We conclude that topical exposure to
carbonless copy paper may cause mast cell/basophil-mediated acute systemic
and potentially life-threatening reactions in susceptible patients

Ref ID: 219
Abstract: Five nonsingers and five singers vocally matched the pitches of
frequency modulated tones. Subject responses to the shadowing task were
analyzed in terms of accuracy, and in terms of duration and speed
characteristics of pitch changes. In addition, each frequency change was
categorized according to hit, overshoot, undershoot, or oscillate patterns.
Singers were found to effect pitch changes in significantly less time than the
nonsingers. This finding was attributed to more direct patterns (hits) and
faster maximum speeds obtained by the singers. Both groups demonstrated a
direct relationship between the size of the pitch change and each of the
duration and speed parameters examined. Similarly, for both groups, pitch
lowering was faster than pitch raising. Faster speeds and more direct paths in
effecting pitch changes were viewed as evidence of greater vocal proficiency
in singers as compared to nonsingers. Implications of the data for mechanical
and physiological aspects of voice frequency control are discussed

Ref ID: 456
Abstract: This study compared a graduated training programme with that of a
traditional teaching method to facilitate the learning of the technique of
fibreoptic nasotracheal intubation. Thirty-two anaesthesia trainees were
randomly assigned to two groups. The graduated programme involved:
practice on a bronchoscopy teaching model; exposure of the epiglottis and
vocal cords in patients recovering from general anaesthesia; performance of
fibreoptic nasotracheal intubation in awake sedated patients. The traditional
programme involved: demonstration (on a patient) of one fibreoptic
nasotracheal intubation by the instructor; performance of fibreoptic
nasotracheal intubation (by the trainee) in awake sedated patients.
Nasotracheal intubation was accomplished significantly more often by the
trainees in the graduated programme (86 out of 96 (89.6%) v. 64 out of 96
(66.5%) (P less than 0.01). The results demonstrate that trainees who
undergo a graduated training programme using simulators are initially more
successful at awake fibreoptic nasotracheal intubation than those who have
learned in the traditional manner, and that the conditions of the investigation
were acceptable to the trainees and patients
(363) Peppard RC, Bless DM, Milenkovic P. Comparison of Young Adult Singers and
Nonsingers with Vocal Nodules. 1988.
Ref ID: 492
Abstract: This study was made to determine if young singers with vocal
nodules perform similarly to nonsingers on a wide range of measures of vocal
function. A group of 20 young adult females (ten singers and ten nonsingers)
with a diagnosis of bilateral vocal nodules were selected for the study. Twenty
women in the same age range, ten of whom were singers and ten nonsingers,
without a diagnosis of vocal disorders served as comparisons. The singers
were all sopranos with at least 2 years of formal voice training. Differences
were noted in a wide range of acoustic, aerodynamic, laryngeal imaging and
psychoacoustic measures between singers and nonsingers with nodules and
between the two groups of normals (singers and nonsingers). Singers with
nodules had smaller nodules, less impairment of vibratory function, and less
severe vocal symptoms than their nonsinging counterparts. Superior ratings
were obtained from the singers without nodules (compared to nonsingers
without nodules) as regards acoustic measures including jitter, shimmer, and
131
signal to noise ratio. Even in the presence of nodules, singers had superior
maximum performance skills than their nonsinging comparisons. The authors
suggest that one reason singers detect problems with their vocal cords earlier
than nonsingers would be a decrease in maximum performance levels. Also
singers have not only themselves as a judge of their voice, but the presence
of a trained listener in the person of their teacher. They are also more highly
motivated to seek immediate aid as singing is their livelihood. These findings
strongly suggest that studies attempting to establish normative data bases for
voice production must differentiate those speakers with singing training from
those without

Strobovideolaryngoscopy in Professional Voice Users: Results and Clinical
Value. 1987.
Ref ID: 498
Abstract: Results were presented of the initial experience of an
otolaryngological practice with stroboscopic laryngoscopy supplemented with
video recording. Over a 2 year period, 486 strobovideolaryngoscopic
procedures, selected because of the presence or suspicion of a structural
abnormality, were performed. Of 343 patients, 311 were professional voice
users, and the others sought medical attention specifically for voice
complaints. After a brief initial examination using visible light, the flexible
laryngoscope was connected to a video camera and the examination
continued using stroboscopic light. Thirty nine different entities were
diagnosed. The most frequent diagnoses in which stroboscopy established or
altered diagnosis or management were scar, nerve paralysis, hemorrhage,
technique, dysphonia, laryngitis, and nodules. The authors conclude that
strobovideolaryngoscopy is useful in establishing the presence or absence of
structural lesions, and that it provides a rapid assessment of vibratory
function of the leading edge of the vocal fold. In selected cases, the
information obtained may establish a diagnosis that otherwise would be
presumptive or missed altogether, and the findings may also result in changes
in surgical judgment

Ref ID: 497
Abstract: Common diagnoses of voice disorders and their treatments were
reviewed. Epidemiologic data on voice disorders were summarized. Anxiety
induced vocal dysfunction was considered. Reassuring the patient was
regarded as the most effective therapy for countering the effects of anxiety
on singers. Vocal dysfunction due to muscle problems, vocal nodules, voice
abuse, upper respiratory tract infection, and tonsillitis was reviewed.
Laryngitis with or without serious vocal injury was discussed. Drugs used for
treating vocal dysfunction were considered. Using speech pathologists and
singing teachers to treat voice dysfunction was discussed. Speech
pathologists were generally regarded as being valuable assets for treating
vocal problems in singers. The helpfulness of singing teachers, under some
conditions, in the treatment of nonsingers with voice problems was described,
since techniques used to develop abdominothoracic strength, breath control,
laryngeal and neck muscle strength, and relaxation are very similar to those
used in speech therapy. Surgery and vocal dysfunction were discussed. Voice
maintenance was considered. The author concludes that excellent regular
training and practice as well as avoiding irritants such as smoke are essential
in preventing vocal dysfunction in professional singers
(367) Sataloff RT. Clinical Evaluation of the Professional Singer. 1987.
Ref ID: 494
Abstract: The medical care and clinical evaluation of voice problems in
professional singers was discussed. It was initially pointed out that most
physicians lack the expertise and experience required to evaluate and treat
subtle voice problems. In order to obtain more accurate diagnostic
information than that provided by the vague terms hoarseness and fatigue, it
was recommended that the patients fill out detailed questionnaires. Following
this, the physician should perform an extensive examination of the larynx.
The indirect laryngoscopy should establish the presence or absence of
nodules, mass lesions, contact ulcers, hemorrhage, erythema, cord paralysis,
arytenoid erythema (reflux), and other possible anatomic abnormalities. It
was considered especially useful to perform the laryngoscopy with the
combination of a fiberoptic laryngoscope and a stroboscopic light source
which might reveal small vibratory irregularities and allow a closer
examination of the vocal cords. The physician also should listen to and
evaluate the singing voice, but without exceeding the limits of his expertise
and without entering the territory of the voice teacher. Finally, it was
emphasized that voice abnormalities may be manifestations of several types
of systemic or neurologic disorders
(368) Sataloff RT. Common Diagnoses and Treatments in Professional Voice Users.
1987.
Ref ID: 496
Abstract: Laryngological problems relevant to the voice professional's ability
to work were reviewed. The author emphasized that careful attention to
individual history and frequent physical examination employed with
professional singers allows detection of subtle organic changes. Gastric reflux
laryngitis was said to be endemic among singers. This may result from fasting
preceding a performance, done to prevent a full stomach from interfering with
necessary abdominal support. Typical symptoms of gastric reflux laryngitis
include hoarseness in the morning, prolonged warmup time, halitosis and a
bitter taste in the morning, frequent throat clearing, chronic irritative cough,
and frequent tracheitis and tracheobronchitis. Voice abuse in singing was said
to be a real hazard for the professional singer. The most common technical
errors in singing were said to involve excessive muscle tension in the neck
and laryngeal muscles, inadequate abdominal support, and excessive volume.
A good voice teacher can be helpful in managing problems and assuring a
nonabusive technique. Voice abuse in speaking frequently occurs, even
among well trained technical singers. Vocal nodules are caused by voice
abuse and usually result in hoarseness, breathiness, loss of range, and vocal
fatigue. Voice therapy is the preferred first therapy, although surgical excision
is sometimes necessary. Vocal polyps, vocal fold cysts, Reinke's edema, upper
respiratory infection without laryngitis, laryngitis with serious vocal fold injury,
laryngitis without serious damage, allergy, hypothyroidism, laryngopathia
premenstrualis, laryngopathia gravidarum, poor general health, aging,
133
substance abuse, and anxiety occurring in professional singers were also
discussed
(369) Sataloff RT. Common Diagnoses and Treatments in Professional Singers.
1987.
Ref ID: 495
Abstract: The diagnoses and treatments of common ailments in professional
singers were discussed. One of the most common afflictions is gastric reflux
laryngitis which occurs because of the singers' habit of eating very late at
night and then going directly to bed. Excessive tension in the muscles of the
neck and larynx while singing and a wrong speaking technique may both
cause voice abuse. To remedy either of these situations, a competent teacher
was recommended. Among anatomical abnormalities of the larynx listed were
vocal nodules, vocal polyps, vocal cord cysts, and Reinke's edema. The causes
and treatments of these inflictions were discussed. Hemorrhage in the vocal
cord area requires strict voice rest. This also may be required in the case of
laryngitis, depending on the cause and seriousness of the inflammation.
During relative voice rest the voice should be used only when necessary, but
during absolute voice rest the voice must not be used at all. In addition to
these ailments, the singing voice may suffer or change as a result of
hormonal changes (thyroid hormones, sex hormones), poor general health,
substance abuse, and anxiety. In all cases, cooperation between a voice
teacher and the physician was recommended

Abstract: The larynx cancer relative risk has been evaluated (328 cases) in
the stationary-native Upper Silesians (63.7%) and migrating (36.3%) male
population. The particular control groups (656 men) included 418 and 238
men respectively not suffering from malignant neoplasms. The essentially
higher larynx cancer incidence risk has been shown for men manual labor and
exposed to the influence of various dusts, gases and vapors and other
pollutants in their place of work. The increased substantial incidence risk is
also true for men who smoke tobacco and are professionally exposed to the
pollution. The results in regard to the consumption of raw and boiled
vegetables suggest that these may be inhibitors of the neoplasmatic process
in the area of larynx (although not only). The frequency of the consumption of
alcohol--vodka or beer--increases the larynx cancer incidence risk both
among autochthons and immigrants. Nevertheless, the data concerning the
amount of alcohol consumed are less valuable here; they do not allow to
establish fully reliable quantitative levels of the beer or vodka consumed. In
comparison with the literature of the subject, divergent data have been
obtained as far as the joint influence of drinking alcohol with simultaneous
smoking of tobacco and professional exposure are concerned

Abstract: Vocal nodules commonly appear in users of professional voice, eg.
singers, in whom strenuous vocal activity is concomitant with emotional
stress. Their appearance is associated with excessive or unusual mechanical
stress at a well-defined localisation of the edge of the vocal folds. The voice
impairment they cause is an occupational illness. This study measures
acoustical characteristics of voice in nodule-carriers by means of Long-TimeAverage Spectra. Dysphonia associated with nodules leads to huskiness and a
tendency towards low pitch

Ref ID: 442
Abstract: The symptoms associated with performance anxiety, or the socalled stage fright syndrome, are similar to those of alpha and beta
adrenergic stimulation. Suppression of symptoms and improvement in
instrumentalist's performance after beta blockade suggest that this modality
would be of benefit for singers as well. To evaluate the dose-effect
135
relationship of beta blockade upon singing performance and the possible
effect of these agents upon performance maturation, we studied 34 singing
students during end of semester juries, using a double-blind crossover
paradigm. Students performed once with either placebo, 20, 40, or 80 mg of
nadolol, and again 48 hours later, with placebo. There was a significant doserelated, limiting effect upon intraperformance cardiac rate. A small, but
statistically significant, dichotomous effect upon performance rating was
noted: low-dose nadolol tended to enhance performance, whereas larger
doses impaired performance. We conclude that the effects of low dose beta
blockade upon singing are minimally helpful and high doses may detract from
performance ability

eligible patients, 93% were interviewed. Increased risks were seen with
alcohol consumption and, less strongly, with smoking, which for all sites could
be adequately fitted by either a multiplicative or an additive model. However,
the site-specific relationships were different, alcohol consumption being
significantly associated only with oral cavity, pharyngeal and extrinsic
laryngeal tumours, and smoking only with intrinsic laryngeal tumours.
Increased risks were associated with low socio-economic status, the
unmarried state, and poor dental care. No significant associations were seen
with specific occupational exposures

Abstract: The work pioneered by Drs. Singer and Blom established the clinical
feasibility of controlled tracheoesophageal fistula for generation of fluent
esophageal speech. There have been numerous practical difficulties that have
been encountered with the use of voice prosthesis. Problems encountered
are: extrusion, speech initiation delay, leakage around the prosthesis, stoma
obstruction, and low volume output. A second generation laryngeal prosthesis
is introduced for comparison. Its design incorporates features that will
significantly improve the clinical problems encountered; extrusion is
minimized; and the new prosthesis allows for one size to fit all patients. A
clinical trial was established to directly compare the artificial speech
generated by the currently existing laryngeal prosthesis. Each laryngectomy
patient was fitted with three different devices and the resulting speech was
evaluated. Video recordings of patients are presented to illustrate the type of
speech produced by each device. Comparisons of intelligibility, fluency,
volume, and patient preference are made. Results indicate that a significant
variation in the speech obtained is critically dependent on the choice of

Abstract: The purpose of the study was to examine the occupational history of
laryngeal cancer patients, and especially their exposure to welding. The
investigation was conducted as a case-control study where all newly
diagnosed patients less than 75 yr of age with cancer of the larynx in
Denmark during March 1980 to March 1982 were selected as cases. For each
case, four age- and sex-matched controls were identified from the municipal
person register in which the case was listed. Data were collected partly by
means of questionnaires and partly by abstracting information from the
medical records of cases. Workers exposed to welding fumes had a slightly
increased risk of cancer of the larynx, most predominantly of cancer of the
subglottic area

Abstract: This paper briefly reviews the available evidence for the influence of
environmental and occupational factors in the development of cancer of the
larynx. Although several occupational exposures have been suggested to play
a role in the etiology of this disease, few have been convincingly confirmed.
The strong association between smoking and cancer of the larynx, the weaker
but still important association between alcohol consumption and cancer of the
larynx, and the strong synergism between the two is emphasized. Other
accepted or suspected environmental and occupational factors are also
discussed

Abstract: Occupational diseases affecting the voice are reviewed. Some
occupational diseases of the voice pertain to conditions of the sound
producing organs. Apart from traumas, these are most often impairments of
the larynx. Other occupational diseases involve the vocal function. These
cover occupations where the use of the voice is preponderant, from teachers
to opera singers. The voice most likely to contract diseases of the vocal
function is the projected voice. In most cases these diseases occur without a
primary permanent lesion, but with a disorder of muscle tone or coordination
of the vocal apparatus. Such functional disorders may result from adoption of
a faulty vocal habit or emotional perturbation frequently related to the
occupation. In some instances a psychosomatic vocal disorder allows an
individual to unconsciously avoid the responsibilities a normal voice would
bring. Particular conditions resulting in voice disorders may include hyperemia
of the free edges of the vocal cords, vasomotor chorditis, and nodules and
polyps of the vocal cords. In addition to the common types of nodules and
polyps, laryngeal contact ulcers and hyperplasia of the vestibular folds are
seen. A common denominator of subjective symptoms is fatigability of the
voice and aggravation of symptoms after vocal effort. Pharmacological
treatment is secondary to vocal rest. Reeducation of vocal habits is generally
required. For some conditions, surgery is indicated. Knowledge of vocal
physiology and of laryngeal hygiene should be included in training for
occupations using the voice extensively. The author concludes that, at early
signs of vocal strain, the subject should reduce vocal output and moderate it

Abstract: Singers and actors who abuse their voices may develop either
polyps, nodules, contact ulcers, and/or contact granuloma. Rarely a vascular
lesion consisting of a hypertrophic vessel projecting above the medial or
superior mucosal surface of the vocal cord is encountered that may contain a
small knucklelike deformity. Clinically this is not dissimilar in appearance to a
vessel found on the anterior nasal septum that is responsible for epistaxis.
When the voice is strained, these vessels can rupture, causing recurrent
submucosal hemorrhages in the professional voice user. The case described is
that of a well-known actress in whom vocal abuse did not produce a
submucosal hemorrhage from the varix but rather an edematous change and
symptoms identical to those of a soft, early vocal cord nodule

Abstract: Examination of the professional singer must include an assessment
of his general health and a thorough ear, nose, and throat evaluation.
However, the physical examination can reveal much more than simply the
appearance of the singer's vocal cords. The physician must be attuned to the
singer's use of his speaking voice. Examination of actual singing allows
specific observations that may substantiate a diagnosis of voice abuse or may
guide the physician in his selection of therapy

workers. Accumulation of cases of cancer of the larynx in a machine factory in
Copenhagen. UGESKR LAEG 1983;145:1623-1628.
Ref ID: 410
Abstract: During the years 1971-76, five metal workers in an average-sized
machine factory in Copenhagen developed cancer of the larynx. This
represents an increased incidence of 114 times the anticipated figure. The
suspicion therefore arose whether an increased risk of cancer of the larynx is
present among metal workers in general and whether a particularly great risk
is present among workers in a machine factory. Although only two out of the
five workers with cancer of the larynx had worked in the present machine
factory over ten years and all five had worked with different working
procedures, the suspicion of a particularly great risk of developing cancer of
the larynx must be maintained because all five worked in the same room with
a great mixture and circulation of atmospheric pollution. Measurements
revealed that known cancer-provoking substances such as chromium and
nickel were present everywhere. These originated mainly from welding of
stainless steel. Only a minority of Danish metal industries work with this. The
occurrence of several cancer-provoking substances in the factory cannot be
excluded as the methods of measurement and the present knowledge of
cancer-provoking substances is limited. The consequences of the above
findings are primarily that the Factory Supervision Authorities issue
instructions that the atmospheric pollution be reduced to values far under the
upper limits both in the factory and in all other metal industries. The present
hygienic limits do not protect the workers from the risk of cancer. The ideal
solution, however, would be to eliminate cancer-provoking substances entirely
from the materials involved. Secondly, the necessity for further research is
emphasized. The newly-developed mutagenic tests on microorganisms must
be emphasized particularly as screening methods for advance assessment of
cancer-provoking properties in substances and combinations of substances.
Animal experiments are necessary for further testing of suspect substances.
Epidemiologial investigations in man may reveal cancer risks under the
influence of certain substances, working processes or types of jobs, although
several decades of exposure must elapse before these are evident. As
139
'experiments' such as these occur in practically every occupation,
epidemiological investigations will still be necessary. The occurrence of cancer
of the larynx forms the basis for an epidemiological investigation of the risk of
developing cancer of the larynx among metal workers in the processing of
stainless steel

Ref ID: 352
Abstract: A case control study of laryngeal cancer was conducted in southern
Ontario between 1977 and 1979 with 204 subjects with newly diagnosed
cancer and 204 controls, individually matched by sex, age, and residence.
Tobacco products and alcohol showed strong associations with cancer of the
larynx for males, with relative risks (RR) for users of cigarettes, cigars or
cigarillos, pipes, and alcohol of 6.1, 2.9, 1.6, and 5.2, respectively. the
population attributable risk percent for males using tobacco products and
alcohol together was estimated to be 94%. Cigarette smoking was also an
important risk factor for females, although the small number of female pairs
(20) precluded any meaningful detailed analysis of other possible risk factors.
The RR for males for exposure to asbestos after the effects of cigarette
smoking were controlled was 2.3, and the effects seemed restricted to
cigarette smokers. The findings on asbestos were based on small numbers of
cases and controls exposed and consequently were subject to large sampling
errors. The estimate was consistent, however, with that from other studies
and supported a causal role for asbestos exposure and cancer of the larynx.
The RR for males for exposure to nickel was 0.9

Abstract: An attempt was made to tract 511 men and women who
manufactured mustard gas during the 1939--1945 war. Despite limitations in
the identifying data available, 428 (84%) were traced to the end of 1974. The
numbers of deaths from all neoplasms combined (45) and from all other
causes (136) were slightly greater than those expected from national death
rates, but not significantly so. Two deaths were attributed to carcinoma of the
larynx and one to carcinoma of the trachea, compared with an expected
number of 0.40 (P less than 0.02). Carcinoma of the larynx was also
mentioned on the death certificate of another man. Seven subjects are known
to have developed cancer of the larynx, compared with 0.75 expected (P less
than 0.001). Excess mortality was also observed from cancer of the lung,
pneumonia and accidents, but the excesses were small and difficult to
interpret

Abstract: Clinical care for professional singers was reviewed. The parts of the
body, including the larynx, supraglottic vocal tract, tracheobronchial tree,
141
lungs, thorax, abdomen, musculoskeletal system, and psychoneurological
system, involved in singing were discussed. The effects of age on the voice
producing mechanisms were considered. The treatment of voice problems was
reviewed. The need to consider the importance that the singer places on
upcoming concerts and the consequences of cancelling engagements, as well
as on his voice in his long term career plans, when choosing a treatment
program for voice disorders was discussed. The effect of factors such as
amount and nature of vocal training, type of singing environment, rehearsal
techniques, vocal abuse, general health, endocrine dysfunction, exposure to
irritants and tobacco smoke, alcohol and drug abuse, and certain foods on
tone production were discussed. Diagnosis and treatment for reflux laryngitis,
anxiety, muscle problems, voice abuse, vocal nodules, upper respiratory tract
infection, and laryngitis with and without serious vocal cord injury were
reviewed. Drugs used for treating vocal dysfunction were described. Voice
maintenance was considered. The author concludes that excellent regular
training and practice and avoiding irritants such as smoke are essential in
preventing vocal dysfunction in professional singers

has suggested that carcinoma of the larynx was an asbestos-related tumour.
In this study, 305 male and 206 female patients were interviewed on
admission to the Royal National Throat Nose and Ear Hospitals in London.
Following endoscopy, biopsy material was reviewed and classified as either
neoplastic, cysts and polyps or inflammatory; a fourth group consisted of
patients for whom the surgeon recorded that the larynx appeared normal on
inspection and from whom no biopsy was taken. Only 15 neoplastic conditions
were detected among the women, and only two had asbestos exposure; thus,
no further analysis was made. Among the males, the neoplastic group was
significantly older than the other groups, and cigarette smoking was
significantly more common. Alcohol consumption did not differ significantly;
and asbestos exposure was not more common in the neoplastic group than in
the three other groups

Abstract: The determination of how much of the discriminative reaction time
(RT) difference between young and old persons could be accounted for by an
age difference in psychomotor latency is discussed. The cumulative
percentage of young and old subjects achieving a given RT is shown. It was
found that 50% of the older subjects and 45% of the younger subjects had a
mean total vocal latency of 333msec or less. The distributions of the young
and old subjects' latencies were quite similar with the old tending to have
shorter vocal reaction times than the young. There was no evidence that the
young and old subjects differed in the speed with which they could initiate a
vocal response to a visual stimulus. A preliminary analysis showed no
interaction between the effect on reaction time produced by the length of the
preparatory interval and that of any other variable, including age. The
existence of a significant age difference in simple psychomotor latency
depended upon the nature of the subjects' response. Results suggest that
slowing psychomotor latency with age is not a general phenomenon, but may
be limited to certain neural systems. It was also shown that respiratory
muscles show little of the age related trophic changes which are seen in other
muscles, including those of the limb

Abstract: A clinico-hygienic investigation was carried out which showed the
major adverse factor (as to the condition of the upper respiratory tract) in
telephone operators to be an intensive vocal effort in the course of their work.
Because of this, they more often suffer from chronic laryngitis and the
incidence of acute and chronic layryngitis (laryngotracheitis) among them is
many times as high as among telegraphists working in identical microclimatic
conditions. For this reason, intensive vocal efforts are considered to be one of
the major factors in the etiology of laryngitis among telephone operators. A
number of measures aimed at preventing chronic laryngitis in telephone
operators are proposed

Abstract: The author analyses the cases of carcinoma of the larynx occurring
in the district of Merseburg in the period from 1966 to 1975 in connection
with asbestos exposure. It is shown that neither the total number nor the
separate age groups deviate from the overall statistics of the GDR. No
significant accumulation of cases can be confirmed in separate branches of
the economy or factories. For this reason recognition of carcinoma of the
larynx as an occupational disease will have to continue being given on the
merits of each individual case, taking into account also other factors pointing
to asbestos exposure. The presence of other signs, such as hyalinoses or
fibroses, are regarded as evidence in support of asbestos exposure. But
further epidemiological studies will have to be conducted in order to arrive at
a definitive conclusion establishing the coincidence between carcinoma of the
larynx and asbestos exposure

Abstract: A case occurred in which polymerized tetrafluoroethylene (116143)
(polytef), injected into the larynx, induced a mass near the thyroid that was
clinically judged malignant. Polytef was injected into the larynx of a 42 year
old male patient with a 3 month history of hoarseness resulting from
idiopathic left vocal cord paralysis. After the injection the patient's voice
improved, but about 10 days later he developed abdominal pain and vomiting,
and the hoarseness recurred. Thyroid scan revealed a cold nodule suggesting
147
localization in the superior pole of the left lobe. Before the neck mass could
be biopsied, it was found that the patient had adenocarcinoma of the ileum
with intraabdominal lymph node metastases. He died 6 months later. Autopsy
revealed that some of the polytef had been injected into an extracordal site
with penetration into adjacent soft tissue of the neck via the cricothyroid
membrane. The foreign body reaction was marked and created a mass 2.3 by
1.5 centimeters, which produced a pressure atrophy of the superior portion of
the left lateral thyroid lobe. The radioisotope findings of the cold nodule
corresponded to the area of the mass, thus suggesting a malignant neoplasm
of the thyroid

Abstract: Numerous occupations demand an optimal speaking capacity. If
occupational vocal disorders (occupational dysphonias) occur, these impair
interpersonal communication and professional performance. Vocal disorders in
and as a result of vocal professions must be differentiated. In general, an
increased frequency of professional dysphonia is to be observed because
numerous new occupational groups demand intensive speech performances.
The findings are largely polysymptomatic and may include psychogenic
disturbances. Questions of treatment, professional ability and prognosis are
discussed

Abstract: An expose of the accidental and occupational damage of the larynx,
with emphasis on the causes and indications for prophylactic measures, is
given. The possibility of the recognition of certain diseases of the larynx as
occupational disease is discussed. In addition to traumas, which increase in
frequency primarily due to traffic accidents, the mechanical, chemical and
physical effects on the larynx are dealt with. Attention is given to the
importance of allergic processes in the larynx with their diagnostic problems
in the occupational disease procedures. The most important infectious
diseases caused by occupational activities are discussed, and the professional
disturbances of the voice are explained, the diagnosis of which was made
perfect by the development of phoniatrics. In the social prognosis of the
prophylaxis and diagnosis of occupational laryngeal diseases, importance is to
be attributed to the tactful collection of data on the occupational history of the
insured patient, the working milieu, and the functional diagnosis; this requires
a close cooperation between occupational medicine and E.N.T. specialists

Abstract: Singer's nodes are small thickenings localized at the junction of the
anterior and middle thirds of the vocal cords. They are frequent conditions
which are not due to inflammation but to excessive use of the voice. This
mechanical factor in straining the voice has a traumatic effect on the larynx.
The prognosis of singer's nodes has been considerably improved by
associating microsurgery with postoperative speech training. Quicker and
better results are attained, with complete recovery of the voice. The
intervention is harmless and can be advised for all forms of nodules of the
vocal cords

Abstract: In the Federal Republic of Germany a register of occupational
diseases is maintained on the basis of which workers qualify for
indemnification. A number of diseases are considered for inclusion on the list
based on experience in Germany and other countries. These include,
byssinosis, farmer's lung, malignomas of the respiratory organs, vibration
diseases, chronic bronchitis, vocal cord nodule, noise effects other than
hearing disorders, degenerative meniscus damage of soccer players, laser ray
damage, and damage done by isocyanate and dimethylformamide. The
question of whether accident insurance should be replaced by a uniform
insurance of all diseases and health damage, regardless of cause, is a
multifactorial problem. (German; English translation available)

Abstract: The health effects of occupational exposure to wood dust were
studied. Dermatological examination was done on 78 individuals from a
furniture factory and an otorhinolaryngological (ORL) examination was done
on 14 workers from another factory. All of these subjects were given an
olfactometric examination at the beginning and end of the work shift for 1
week. Additionally, pulmonary examinations were done on 53 machine and
manual sanding operators with an average exposure duration of 6.5 years.
The dust concentrations in individual work shops varied from 40 to 80
milligrams per cubic meter (mg/cu m); in the machine sanding shops, this
value was as high as 190mg/cu m. All subjects examined had been exposed
to many woods including oak, beech, walnut, poplar, maple, pine, and spruce
and the tropical woods dibetou, abachi, avodire, mahogany. Some employees
had been exposed to Mansonia and African pear. Atrophic mucosa was evident
in 47.8 percent of the subjects, blood vessel dilation in Kiesselbach's area in
39.1 percent, mucosal lamellar irritation in 20.6 percent and active lesions
and petechiae in 18.4 percent. Short term exposure caused irritation of
respiratory tract mucosa manifested by sneezing, coughing and then bronchial
and pulmonary symptoms. A thickening of vocal cords and a reddening of
vocal cords were seen in 56.6, and 38.0 percent of the workers respectively.
Evidence of unilateral or complete anosmia was noted in 17 percent of the
subjects. Workers exposed to Mansonia reported scratchiness of the throat
and hoarseness. Isolated cases of local toxic effects of Mansonia splinters
were observed, including redness, edema and increased size of lymph nodes.
Skin damage due to Monsonia and African pear occurred in 34.6 and 25.0
percent of the exposed workers, respectively. Pulmonary reticulation was
found in 2 wood sanders. The author concludes that the adverse health
effects of wood dust are due mostly to the chemical properties of the wood.

Abstract: Este trabajo presenta los primeros resultados empķricos obtenidos
al utilizar un protocolo interdisciplinar ("Teatinos") en la evaluación funcional
de pacientes con trastornos de la voz. El objetivo es propiciar una mejor
detección de las variables de pronóstico, recuperación y prevención de las
disfonķas. Los resultados del estudio, llevado a cabo en 8 pacientes con
nódulos bilaterales y disfonķa, muestran los efectos de los distintos
parįmetros e ķndices multidimensionales valorados en la fase pre-tratamiento.
Todos los pacientes manifestaron tras la rehabilitación funcional (fase posttratamiento) una mejorķa subjetiva en el bienestar vocal, en el grado de
satisfacción con su voz, ademįs de una disminución de la ronquera y un
aumento de la extensión vocal. Asimismo, se observa una desaparición o
reducción de los nódulos vocales, un menor grado perceptual de la disfonķa,
una mejora de los parįmetros acśsticos y una recuperación significativa de los
ķndices aerodinįmicos. Por ejemplo, los resultados muestran una mejora de
un 22,5 por ciento en el Tiempo Mįximo de Fonación (TMF) al comparar la
fase pre vs. resultados en la evaluación de la efectividad del tratamiento

Abstract: Presentamos un estudio sobre la evaluación objetiva de la voz en
100 adultos sanos y en 60 sujetos con disfonķa por nódulos o pólipos vocales.
A todos se les realizó una laringoestroboscopia y un anįlisis acśstico vocal. Se
registró y digitalizó la vocal "a" con el programa Dr. Speech Science. Se
estimaron los parįmetros: frecuencia fundamental (Fo, expresada en función
del sexo), jitter, shimmer y Ruido Glótico (NNE, HNR y SNR). La Fo en el
grupo normal fue de 139.72 en varones y 267.33 en mujeres, jitter 0.24 y
shimmer 2.10. En pacientes disfónicos por nódulos Fo fue 126.96 en varones
y 240.72 en mujeres, jitter 0.35 y shimmer 3.25. En pacientes disfónicos por
pólipos Fo fue 119.75 en varones y 218.26 en mujeres, jitter 0.50 y shimmer
4.34. Todas estas diferencias fueron estadķsticamente significativas. El Ruido
Glótico en población normal fue de: NNE -13.62, HNR 24.07 y SNR 24.49; en
pacientes con nódulos: NNE -10.65, HNR 25.21 y SNR 25.55; en pacientes
con pólipo vocal: NNE -8.24, HNR 29.63 y SNR 28.22. Sólo existió diferencia

Abstract: Este artķculo revisa la intervención logopédica en alteraciones de la
voz considerando cuatro dimensione -la orgįnica, la funcional, la social y la
personal - que permiten una comprensión global del problema que plantean al
logopeda las personas con disfonķa. Atendiendo globalmente al problema se
plantea un modelo de intervención interactivo, funcional y personalizado en el
que la adaptación individual a las cuatro dimensiones mencionadas resulta
esencial en el proceso terapéutico. Se constituyen como componentes bįsicos
de la intervención: la información dada al paciente, la elaboración de un mapa
de funcionamiento vocal que ponga de manifiesto la interconexión de los
componentes de la técnica vocal en cada caso, el aprovechamiento de los
contextos naturales en los que se utiliza la voz y la atención a la perspectiva
del paciente, a su queja, a su vivencia del problema y de la intervención.
Estos aspectos sirven de marco y dan sentido a los ejercicios propuestos y a

Abstract: El presente trabajo es un estudio descriptivo y retrospectivo de las
bajas por patologķa vocal de los maestros de Educación Primaria en la Ciudad
Autónoma de Cueta, territorio MEC, durante los cursos 98/99 y 99/00. En él
se abordan diversos aspectos sobre trastornos de voz en el colectivo docente,
tales como: comprensión general de la patologķa vocal en el profesorado,
incidencia de la misma sobre el colectivo, anįlisis de la distribución de bajas
por género, edad, tipo de patologķa y duración de las mismas, asķ como
comparación de estos resultados con otros estudios anįlogos. Finalmente,
realizamos un anįlisis de la incidencia que este tipo de patologķas tienen en
los aspectos organizativos y algunas sugerencias o recomendaciones para
mejorar este tipo de trastorno en el colectivo docente. Los resultados del
estudio arrojan las siguientes conclusiones. La patologķa vocal es
significativamente superior en la mujer. En relación a la edad la franja
comprendida entre 30-39 ańos es la mįs afectada y la media recogida es de
47 ańos, coincidente con estudios anįlogos. Se constata la alta tasa de la
patologķa de la voz de los maestros que causan baja laboral por gripe y
laringitis que habitualmente derivan en disfonķas. Se pone de manifiesto la
necesidad de establecer nuevos criterios de clasificación de las distintas
patologķas respiratorias y alteraciones de la voz que permitan un mejor

Abstract: Objetivos. Valorar la importancia de la carga de trabajo en la
patologķa vocal de los docentes considerando el tiempo de exposición y la
dosis horaria, asķ como los efectos de otros factores potencialmente
asociados a dichas alteraciones.Métodos. Se realiza un estudio transversal con
muestreo bietįpico a partir del registro del Servicio de Prevención de ASEPEYO
en Madrid. Se estudian 245 docentes procedentes de centros de enseńanza
primaria, secundaria y universitaria a través de un cuestionario de
autoaplicación, con posterior anįlisis estadķstico de los datos.Resultados. Se
identifican 85 profesores con sķntomas de patologķa vocal (prevalencia
34,7%). El sķntoma principal es la alteración del timbre de la voz (95,3%).
Un 31,8% pierde la voz por completo. Son mįs frecuentes los trastornos de la
voz en quienes han trabajado mįs ańos (tiempo de exposición), en las
mujeres y en los que padecen trastornos del sueńo, ansiedad y reflujo
gastroesofįgico, con diferencias estadķsticamente significativas. Ademįs, hay
mįs consultas al logopeda y aumenta el nśmero de bajas laborales en los que
padecen alteraciones de la voz. No existen diferencias entre sintomįticos y
asintomįticoscon respecto a la dosis horaria de uso de la voz, consumo de

tabaco o alcohol, ni consumo de medicamentos.Conclusiones. Se ha
encontrado una proporción alta de docentes con sintomatologķa relacionada
con la voz, principalmentetrastornos de carįcter funcional. Se pone de
manifiesto la necesidad de detectar precozmente estas alteraciones y
establecer medidas preventivas. El cuestionario puede ser un buen método de

Methods. A cross-sectional study was conducted with a two-tiered sample.
The study involved 245 teachers from the primary, secondary and university
levels, using a self-administered questionnaire with subsequent statistical
analysis of the data. Results. Eighty-five subjects exhibited symptoms (34.7%
prevalence rate). The main symptom was alteration of voice tone (95.3%). Of
those studied, 31.8% indicated complete voice loss. Voice disorders were
more frequent among the most veteran teachers (exposure time), women,
those suffering from sleep disorders, anxiety and gastroesophageal reflux,
exhibiting statistically significant differences. Those affected turn more
frequently to speech therapists for help when symptoms have already
manifested themselves, and the number of teachers with voice disorders on
sick-leave increases. No differences were found between symptomatic and
asymptomatic subjects with regard to exposure time, tobacco use and
consumption of alcohol or pharmaceuticals. Conclusions. A high percentage of
teachers exhibiting voice-related symptoms, especially functional disorders,
was found. This draws attention to the need for early detection of these
disorders and for preventive measures. The questionnaire could be a good
tool for initial detection of the problemîEn

The management of voice disorders requires a close collaboration between
the throat surgeon and the speech therapy team. The diagnosis of cordal
lesions is essential to an accurate therapy. Stroboscopy contributes functional
information which is useful to decide between microsurgery, vocal reeducation
or a combined treatment. We have reviewed our phonomicrosurgery cases for
the past five years and analyzed the correlation between preoperative
diagnosis obtained by stroboscopy and intraoperative findings. In 90% of
cases there exists a relation between both diagnoses. We consider
stroboscopy as an essential means of evaluation to establish an adequate

antecedentes profesionales y los personales, el ambiente del aula y se realizó
una exploración completa de la voz: pruebas aerodinįmicas, tono y extensión
de voz, anįlisis acśstico de la voz, evaluación perceptual de la voz y
videolaringo-estroboscopia para realizar el diagnóstico. Los docentes mįs
jóvenes y con menos ańos de ejercicio profesional presentaban una mayor
tendencia a padecer nódulos que los docentes normales. El ambiente seco y
la existencia de ruido y de eco en la clase eran mįs frecuentes en los docentes
con nódulos. Los antecedentes con mayor influencia en el desarrollo de los
nódulos fueron: la patologķa vocal previa, la microcirugķa larķngea, la cirugķa
nasal y el reflujo gastro-esofįgico. Los docentes con nódulos tenķan el rango

rondas consecutivas. Han participado 43 profesores de 180 seleccionados (24
por ciento), aleatoriamente, entre los afiliados y afiliadas a la Federación de
Enseńanza del Sindicato Comisiones Obreras (CC.OO.) en Cataluńa que
trabajaban en centros pśblicos de Barcelona.Resultados: Los factores
identificados, con diferente grado de importancia, por el profesorado de
enseńanza primaria y secundaria, ponen de manifiesto que las principales
causas por las que se puede enfermar a consecuencia del trabajo profesional
son de carįcter psicosocial. La complejidad de atención al alumnado con
problemas de aprendizaje y la desmotivación de éste son, respectivamente,
los factores mįs puntuados en enseńanza primaria y secundaria. La demanda
y delegación de problemas y conflictos, los problemas de disciplina, la falta de
colaboración entre compańeros y de reconocimiento social, el exceso de
horario lectivo y la incertidumbre sobre los resultados de los alumnos
completan los factores mįs votados. Los problemas musculosqueléticos y de
esfuerzo vocal aparecen con una menor significación y solamente en
enseńanza primaria. Conclusiones: Los resultados obtenidos en el presente
estudio ponen de manifiesto que los factores psicosociales constituyen los
principales riesgos laborales que afectan a la salud y el bienestar del
profesorado. Considerando las caracterķsticas de los factores manifestados,
es necesario promover entre el profesorado acciones destinadas a mejorar la
satisfacción laboral entre el colectivo docente, asķ como otras de apoyo para

Speech is an attribute of the human species. Central speech disorders
following stroke are unique modelsfor the investigation of the organization of
speech. Achievements in neurobiology suggest that there arepossible
neuroendocrine mechanisms involved in the organization of speech. It is
known that theneuropeptide vasotocin, analogous of vasopressin in mammals,
modulates various components ofvocalization in animals. Furthermore, the
positive influence of vasopressin on memory, which plays animportant role in
the formation of speech, has been described. In this study, speech
organization processesand their recovery with the administration of
vasopressin (1-desamino-8-D-arginin-vasopressin) to 26patients with chronic
aphasias after stroke were investigated. Results showed that sub-endocrine
dosesof the neuropeptide with intranasal administration had positive influence
primarily on simple forms ofspeech and secondarily on composite forms.
There were no statistically significant differences betweenthe sensory and
integrative components of the organization of speech processes with
vasopressin. In allcases, the positive effect of the neuropeptide was
demonstrated. As a result of the effects, speech regulatedby both brain
hemispheres improved. It is suggested that the neuropeptide optimizes the
activity both inthe left and right hemispheres, with primary influence on the
right hemisphere. The persistence of theacquired effects is explained by an
induction of compensatory processes resulting in the reorganizationof the

Abstract: Vocal nodules (singer's nodules) are a typical professional disease of the vocal apparatus. This disease occurs more frequently in 20- to 50-year-old singers. The
nodules form because of vascular disorders secondary to overstrain of the vocal apparatus in phonation and disorders of vegetative innervation. 43 opera singers were treated
whose age and singing history ranged from 22 to 57 years and 3 to 26 years, respectively. The treatment combined psychotherapy, medicines with phlogenzym as a basic
drug, physiotherapy and phonopedia. Phlogenzym allows to avoid "silence regimen", sur gical intervention. This improves treatment efficacy, shortens the time of disability for
singers.

Medium: print
Language: Russian
Abstract: Whether physiologically correct singing promotes disappearance of vocal nodules (VN) was studied in 27 professional classic style singers having VN for 20 years.
VN arose primarily in women, tended to recur. As shown by examination with laryngostroboscope, electroglottograph and sound level meter, physiologically correct singing
resulted in temporary disappearance of soft nodules but hard nodules did not resolve. It
is inferred that professional singing is not recommended for subjects with hard vocal
nodules.

Abstract: Phonomicrosurgery in performing artists has historically been approached with
great trepidation, and vocal outcome data are sparse. The vocal liability of surgically dis turbing the superficial lamina propria (SLP) and epithelium must be balanced with the in herent detrimental vocal effect of the lesion(s). A prospective investigation was per formed on 185 performing artists who underwent phonomicrosurgical resection of 365
lesions: 201 nodules, 71 polyps, 66 varices and ectasias, 13 cysts, 8 keratotic lesions, 2
granulomas, 2 Reinke's edema, and 2 papillomas. Nearly all patients with SLP lesions re ported improvement in their postsurgical vocal function. This subjective result was sup ported by objective acoustic and aerodynamic measures. All postsurgical objective vocal
function measures fell within normal limits, including a few that displayed presurgical ab normalities. However, given the relative insensitivity of standard objective measures to
assess higher-level vocal performance-related factors, it is even more noteworthy that 8
of 24 objective measures displayed statistically significant postsurgical improvements in
vocal function. Such changes in objective measures mostly reflect overall enhancement
in the efficiency of voice production. Phonomicrosurgical resection of vocal fold lesions in
performing artists is enjoying an expanding role because of a variety of improvements in
diagnostic assessment, surgical instrumentation and techniques, and specialized rehabil itation. Most of these lesions are the result of phonotrauma and arise within the SLP.
Successful management depends on prudent patient selection and counseling, ultrapre cise technique, and vigorous vocal rehabilitation. Furthermore, an understanding of the
vocal function and dysfunction of this high-performance population provides all
otolaryngologists who manage laryngeal problems with valuable information that they
can extrapolate for use in their practices.

Abstract: The proposal of this basic protocol is an attempt to reach better agreement
and uniformity concerning the methodology for functional assessment of pathologic
voices. The purpose is to allow relevant comparisons with the literature when
presenting / publishing the results of voice treatment, e.g. a phonosurgical technique, or
a new / improved instrument or procedure for investigating the pathological voice. Metaanalyses of the results of voice treatments are generally limited and may even be impossible owing to the major diversity in the ways functional outcomes are assessed. A
multidimensional set of minimal basic measurements suitable for all "common" dys phonias is proposed. It includes five different approaches: perception (grade, roughness,
breathiness), videostroboscopy (closure, regularity, mucosal wave and symmetry),
acoustics (jitter, shimmer, Fo-range and softest intensity), aerodynamics (phonation quo tient), and subjective rating by the patient. The protocol is elaborated on the basis of an
exhaustive review of the literature, of the experience of the Committee members, and of
plenary discussions within the European Laryngological Society. Instrumentation is kept
to a minimum, but it is considered essential forprofessionals performing phonosurgery.

Abstract: Vocal disorders are very common occupation-related disease in teachers.
Their remarkable incidence might be associated with inappropriate techniques of speech
and poor vocal hygiene. The aim of this study was to assess the function of vocal organ
including voice emission technique in persons starting their teaching occupation. The
study group included 66 female students at Teaching College. Their were thoroughly interviewed and subjected to laryngological, phoniatric and videostroboscopic examina tions. All subjects reported subjective symptoms after vocal effort. Hoarseness and
throat dryness were the most common. In the majority of students functional vocal dis orders were observed. In 30% of them insufficiency of glottis and in four (6.1%) students soft vocal nodules were found. Signs and symptoms of vocal diseases were more
frequent in a subgroup of students exposed to increased vocal effort during theirprofessional education. The results indicate that young teachers are not sufficiently prepared
for increased vocal strain, apparently associated with theirprofession. It is indeed necessary to introduce preventive programs including special training of appropriate speech
technique, into the curricula of schools for teachers.

Abstract: A questionnaire to determine the characteristics of vocal problems was distributed to 75 female aerobic instructors and 75 female aerobic participants ranging in age
from 20 to 40 years. Of the questionnaires returned, 50 from each group, with completed replies to all questions, were selected for inclusion in the study. The question naires, constructed by the investigator, included pertinent questions relative to length of
teaching/participating experience, average number of classes taught/participated in
weekly, number of classes taught/participated sequentially, type of aerobics, medical his tory and history of vocal problems and/or conditions, water intake daily and during in structing/participating, sleep habits, and smoking habits. The results indicated that aer obic instructors generally experienced more hoarseness and episodes of voice loss during
and after instructing and a significantly higher prevalence of nodules. The group differ ences in reported unrelated episodes of hoarseness, however, were quite similar. The
results suggest that aerobic instructors experience a higher prevalence of vocal problems
when compared to individuals participating in aerobics.

Abstract: Effects of the surgical removal of the vocal polyps and nodules in 33 patients
were evaluated by spectral analysis. A comparison of the vocal register, falsetto as well
as noise component was made pre- and postoperatively. The human voices of these
cases were showed in digital and graphic forms under the control of computer. In order
to obtain a statistical analysis comparisons of data of mean values were made using the
Students t-test. According to the results from the present study, it could be concluded
that the effects of the surgical procedures could be evaluated objectively and quantitat ively, and that spectral analysis could provide reliable evidence for the comparison of the
effects of various surgical procedures and for the evaluation of vocal ability following the
phonosurgery for the patients who were professional singers or other speakers such as
teachers and shop assistants.

Abstract: As most specialists know, one of the most important factors for professional singers is the ability to master correct breathing. It has been observed that the
breathing pattern used when yawning is very similar to the breathing pattern used while
singing the Italian Bel Canto. The authors treated 91 cases suffering from singers nodules, recurrent nerve paralysis and glottal chink. Patients were given clinical voice train ing utilizing the "yawning" breathing pattern. In judging the results, objective standards
were designed for evaluation of phono-exams. The effects have been analysed statistically. They showed that the therapy using the yawning-like breathing pattern is effective
for those dysophonic symptoms.

Abstract: The purpose of the present investigation was to describe the occurrence of
laryngeal pathologies and their distribution across age, sex, and occupation in a group of
persons seeking physician treatment. Data were collected on 1,262 patients seen by
eight otolaryngologists from three different residential areas. The five most frequent
pathologies reported were nodules, edema, polyps, laryngeal cancer, and vocal fold paralysis. For the total sample, pathologies occurred more frequently in females than in
males; however, certain pathologies were more common to one sex than the other. The
voice-disordered population appears to be getting older. The top five occupations associated with laryngeal pathologies were retired persons, homemakers, factory workers, unemployed, and executive/managers. Comparisons with similar investigations were
made.

Abstract: The purpose of this study was to determine the validity and reliability of using
perceptual ratings for assessing voice quality in patients with vocal fold nodules or
polyps. A 13-dimension perceptual rating system was modeled after systems currently in
clinical use. To meet the criterion of 80% mean interjudge reliability, eight hours of train ing were required for four previously inexperienced listeners. Extended vowel phonations
of patients and controls were then rated blindly by the same listeners. Interjudge reliab ility was greater than .90 for three dimensions judged in the pathological phonations,
while intrajudge test-retest agreement was less than 75% on five dimensions. Validity
was demonstrated with 100% correct assignment to group by computing a discriminant
function employing all dimensions. Despite the extensive training procedures used, our
reliability data were not comparable to those reported when highly experienced judges
have been used, suggesting that the task of perceptually rating voice quality is difficult
and requires extensive professional experience.

Teaching is one of the main economical sectors. Teachers require an optimum level
of occupational health to adequately perform their task. Since the entry into force of
Real Decreto 1299/2006, "Nodules of the vocal cords because of the sustained efforts of
the voice for professional reasons" constitute an occupationaldisease for teachers, a
new issue for this group. The purpose of this paper is the proposal of a procedure for
monitoring the health of the teaching staff. This is a matter that arises from an epidemi ological research in order to find out how a representative sample of secondary education teaching staff could fall ill, considering variables of occupational health. The most
frequent pathology appearing in the surveyed population was analysed, among which
disorders of the voice were found including vocal cord nodules. The importance of diagnosing this disease requires it to be included in medical check-ups done to the teaching
staff for the Health Surveillance. Hence, a procedure to facilitate the specific health
exam, as well as the approach for its possible diagnosis were proposed. 19 ref.

Abstract: Objectives/Hypothesis. This article describes the prevalence of laryngeal
pathology in a treatment-seeking population with dysphonia in the Flemish part of Belgi um.
Study Design. Retrospective investigation.
Methods. During a period of 5 years (2004-2008), data were collected from 882 patients who consulted with dysphonia at the ear, nose, and throat department of the Uni versity Hospital in Ghent (Belgium). Laryngeal pathology was diagnosed using video stroboscopy. Ages ranged from 4 years to 90 years.
Results. Functional voice disorders were most frequently diagnosed (30%), followed
by vocal fold nodule (15%), and pharyngolaryngeal reflux (9%). The role of age, gender,
and occupation was investigated. Pathologies were significantly more common in females
than in males, representing 63.8% and 36.2% of the population, respectively. Professional voice users accounted for 41% of the workforce population, with teachers as
main subgroup. In professional voice users, functional dysphonia occurred in 41%, vocal fold nodules in 15%, and pharyngolaryngeal reflux in 11%. Our data were compared
with data from other countries.
Conclusions. Functional voice disorders were overall the most common cause of
voice disorders (except in childhood), followed by vocal fold nodules and pharyngolaryn geal reflux. Professional voice users accounted for almost one half of the active population, with functional voice disorders as the main cause of dysphonia.

Abstract: Purpose
This article presents the current state of knowledge regarding vocal hygiene for the
voice professional.
Recent findings
Research regarding vocal hygiene has primarily focused on two areas: vocal hygiene
as a preventive strategy, and vocal hygiene as a management technique for individuals
with voice disorders. It is difficult to assess the effectiveness of vocal hygiene as a pre ventive tool as programs are often expensive leading to limited data. Vocal hygiene as a
sole strategy for the treatment of voice disorders has shown minimal, but favorable results. As a component of a comprehensive therapeutic program, it is difficult to isolate the
influence of vocal hygiene. However, limited components of vocal hygiene including hy dration and vocal rest have been associated with improved therapeutic outcomes. In ad dition, the current literature proposes a paradigm shift away from more restrictive therapy approaches to a holistic approach to vocal well being.
Summary
Vocal hygiene should be considered only as a component of a broad vocal rehabilitation program. The role of vocal hygiene as a means to prevent voice disorders remains
unproven. Additionally, some of the findings may be applied to both dysphonic and
healthy individuals in order to facilitate vocal well being.

Abstract: The European Laryngological Society (ELS) has published a protocol for the
evaluation of vocal function. Using this protocol, we evaluated 17 female sopranos, of
whom 11 had laryngostroboscopic findings of organic alterations and six did not. Singers
with increased subjective impressions of hoarseness, or of whom the examiner had increased perceptions of hoarseness, showed significant differences regarding impairment
of the maximum phonation time, the frequency range, and the dysphonia severity index.
No such differences were found regarding the presence of alterations of the vocal folds.
These data suggest that organic alterations in professional singers are not necessarily
associated with impaired vocal performance or vocal function or with measured values of
the ELS protocol. For professional singers, therapy should be indicated not just on the
basis of stroboscopy but on a broader basis using multifactorial voice analysis such as
the ELS protocol.

Abstract: The purpose of the present study was to calculate the prevalence and incidence of voice disorders among teaching staff and find out the associatedoccupational risk factors. A case-control study was performed with 905 teachers, 579 cases and
326 controls; 492 were randomly selected and 413 volunteered. All teachers were asked
to fill out a standard questionnaire. Next, a complete laryngeal exam, was performed in cluding a general ear, nose, and throat evaluation and videolaryngostroboscopy. The prevalence of voice disorders among teaching staff was 57%. The most prevalent lesions
were vocal overstrain (18%), nodular lesions (14%), and hyperfunctional dysphonia
(8%). The incidence rate was 3.87 new cases per year per 1000 teachers. Women had
organic lesions three times more than men (odds ratio [OR]: 3.52, confidence interval
[CI]: 2.04-6.09). However, men had chronic laryngitis three times more than women
(OR: 2.93, CI: 1.50-5.71) and functional dysphonia nearly twice more than women (OR:
1.81, CI: 1.21-2.69). We find a significant risk of suffering voice disorders in teachers
who smoke daily (OR: 2.31, Cl: 1.58-3.37) and who drink several cups of coffee or tea
(OR: 1.87, CI: 1.36-2.56). It is advisable to carry out an annual evaluation of all teaching staff on account of the high prevalence of voice disorders among them.

Abstract: In order to test the hypotheses that nonsurgical treatment and elimination of
inappropriate use of the voice is sufficient for disappearance of vocal fold nodules (VN),
28 classical singers with these lesions were examined for a period of up to 24 years after
establishing this diagnosis. Twenty vocally healthy female singers constituted the control
group. Laryngoscopy, microlaryngoscopy, laryngostroboscopy and acoustic voice analyses were used to carry out this research. It was found that VN, having once occurred,
tended to reoccur despite nonsurgical treatment and the elimination of incorrect singing.
It was concluded that physiologically correct singing leads only to a temporary disap pearance of soft nodules and does not promote the resolution of hard nodules.

Abstract: Vocal fold masses are often complex in nature and can have a devastating
result on the professional voice. These lesions are usually multifactorial with synergistic
contributions over time from voice use demands and technique, medical conditions,
medications, and the environment. General categories of benign vocal fold masses
in professional voice include nodules, polyps, and cysts, but other pathology should be
considered, such as reactive lesions, intracordal scarring, feeding varices, and reparative
granuloma. A perspective on these issues is essential for proper diagnosis and manage ment. Video procedures for nodule and polyp surgery accompany this content online.

Abstract: Professional voice users comprise 25% to 35% of the U.S. working population. Their voice problems may interfere with job performance and impact costs for both
employers and employees. The purpose of this study was to examine treatment outcomes of two specific rehabilitation programs for a group ofprofessional voice users.
Eighteen professional voice users participated in this study; half had complaints of
throat pain or vocal fatigue (Dysphonia Group), and half were found to have benign vocal
fold lesions (Lesion Group). One group received 5 weeks of expiratory muscle strength
training followed by six sessions of traditional voice therapy. Treatment order was reversed for the second group. The study was designed as a repeated measures study with
independent variables of treatment order, laryngeal diagnosis (lesion vs non-lesion),
gender, and time. Dependent variables included maximum expiratory pressure (MEP),
Voice Handicap Index (VHI) score, Vocal Rating Scale (VRS) score, Voice Effort Scale
score, phonetogram measures, subglottal pressures, and acoustic and perceptual measures. Results showed significant improvements in MEP, VHI scores, and VRS scores, sub glottal pressure for loud intensity, phonetogram area, and dynamic range. No significant
difference was found between laryngeal diagnosis groups. A significant difference was
not observed for treatment order. It was concluded that the combined treatment was responsible for the improvements observed. The results indicate that a combined modality
treatment may be successful in the remediation of vocal problems for professional voice users.

Abstract: OBJECTIVE: To design a grading scale for vocal fold nodules in pediatric pa tients.
STUDY DESIGN AND SETTING: We conducted a prospective study in which a grading scale for vocal nodule size and contour based on static fiberoptic images of pediatric
larynges was developed to achieve the scale presented here.
RESULTS: Twenty-eight health care professionals each rated 28 images of pediatric vocal fold nodules. The intraclass correlation for nodule size was strong (0.77; 95%
confidence interval, 0.67-0.87). The kappa statistic for nodule contour was mild (0.35;
95% confidence interval, 0.33-0.37). Agreement between experienced and other raters
found no significant difference for the nodule size or contour grade of a given image.
CONCLUSIONS: A grading scale for pediatric vocal fold nodules is presented. Interrater reliability for nodule size is high and can be reliably used by health care professionals with varying levels of experience.
SIGNIFICANCE: A validated grading scale facilitates objective analysis of outcomes
when studying and following patients with vocal nodules. (C) 2007 American Academy of

Abstract: An important clinical component in the prevention and treatment of voice dis orders is voice care and hygiene. Research in voice care knowledge has mainly focussed
on specific groups of professional voice users with limited reporting on the tool and
evidence base used. In this study, a questionnaire to measure voice care knowledge was
developed based on "best evidence." The questionnaire was validated by measuring specialist voice clinicians' agreement. Preliminary data are then presented using the voice
care knowledge questionnaire with 17 subjects with nonorganic dysphonia and 17 with
healthy voices. There was high (89%) agreement among the clinicians. There was a
highly significant difference between the dysphonic and the healthy group scores (P =
0.00005). Furthermore, the dysphonic subjects (63% agreement) presented with less
voice care knowledge than the subjects with healthy voices (72% agreement).
The questionnaire provides a useful and valid tool to investigate voice care know ledge. The findings have implications for clinical intervention, voice therapy, and health
prevention.

Abstract: Objective: Steroid injection into the larynx has been sporadically reported as
helpful in benign lesions of the larynx. Its role in laryngology remains unclear. This study
reviews the indications and results of 47 steroid injections in 34 patients in an office set ting. Methods: The authors conducted a retrospective review of 47 injections in 34 patients. Methylprednisolone acetate suspension, USP (40 mg/mL), was injected by indirect
laryngoscopy under local anesthesia. Results were evaluated by stroboscopy and by perceptual evaluation of the GRABS scale before and after injection. Pre- versus postinjection ratings were compared by paired t test. Results: Indications for injection were: 1)
postoperative scar with local stiffness (12 patients), 2) vocal nodules and polyp (18 pa tients), and 3) sarcoidosis/granuloma (4 patients). Steroid injections were done in professional singers instead of repeated oral administration of steroids and/or to avoid sur gery in patients with polyps and cysts. Improvement was noted in 28 of 34 (82%). Eleven of the 18 patients with polyps and nodules had significant improvement and avoided
surgery. Vocal fold scars improved after injection with an improved voice grade (P <.01),
an improved amplitude (P <.05), and improved mucosal wave (P <.05). There were no
complications. Only two patients could not tolerate office injection. Conclusion: Office
steroid injections are a valuable adjunct in management of vocal fold scars, polyps, nod ules, and granulomas.

Abstract: Teachers are prone to developing voice problems because of the specific occupational demand of teaching. Voice problems impose difficulties or limitations not
only on their teaching activities but also on other daily voice activities. Activity limitation
and participation restriction are two separate dimensions introduced in the International
Classification of Impairments, Disabilities, and Handicaps by the World Health Organiza tion (1997). Teachers with voice problems may face difficulties or limitations in their
teaching activities. However, they may have little choice but to continue participating in
these teaching activities. This study reports the extent of voice problems and their im pact on 30 self-selected teachers enrolled for a workshop to improve their teaching
voice. The findings show that job, daily communication, social communication, and emo tion were all affected in the majority of the teachers. It also points to the need of imple menting preventive voice care for the teaching profession.

Abstract: The acceptance of voice disorders by day care center teachers as an occupational disease is not an invariably established practice. This is due to the lack of reliable
evidence of a higher risk for voice disorders in this profession. To find out the risk of
voice disorders, an epidemiological study was conducted among day care center teachers
(n = 262)., using hospital nurses (n = 108) as a control group. Symptoms were charted
by a questionnaire. In a clinical examination made by a laryngologist, the voice quality
was assessed and the laryngeal status noted. Teachers at day care centers had significantly more voice disorders than did nurses. Vocal nodules and laryngitis findings ap peared significantly more frequently among day care center teachers than among those
in the control group. The results prove voice disorders to be more frequent among day
care center teachers than among control group subjects, and also that the main cause
for this may be a higher vocal loading among day care center teachers than among control group subjects.

Abstract: The Voice Handicap Index (VHI) was developed to assess patients' perception
of the severity of their voice disorder. The purpose of this study was to determine the degree of handicap expressed by professional and recreational presenters with a voice
complaint. Singers (n = 106) and nonsingers (n = 369) with voice symptoms were studied. The results of the VIII for singers indicate that singers score significantly lower (less
severe) on the VHI compared to nonsingers. Singers with vocal fold nodules had a lower
mean VHI than singers with vocal fold cysts or polyps. Singers who perform classical mu sic had the lowest mean VHI of all types of singers studied. A low VHI in singers may
represent a significant handicap and should not be ignored when considering the severity
of a singer's voice problem.

the frequency of HGA was different in hyperfunctional voice patients with and without
vocal fold masses. One hundred and forty-seven subjects were studied. All subjects re ceived a complete otolaryngological evaluation including strobovideolaryngoscopy, ob jective voice measures, and evaluation by a speech-language pathologist. Thirty-two pa tients were diagnosed with muscle tension dyshonia (19 male, 13 female) without vocal
fold masses. Fifty-seven patients were diagnosed with unilateral vocal fold masses (29
male, 28 female), most of which were cysts. Fifty-eight patients were diagnosed with bi lateral vocal fold masses (13 male, 45 female). Of the 45 females with bilateral vocal fold
masses, 26 had a vocal cyst and reactive nodule and 19 had bilateral vocal fold nodules.
The control group was balanced and matched based on sex and on percentage of singers
and nonsingers. It consisted of 49 subjects with no vocal fold pathology (20 male, 29 fe male). The group was composed of professional speakers, singers, and nonprofessional
speakers. AU voice disordered groups demonstrated higher frequencies of HGA than the
control group. Differences were found between the male and female subjects in this
study. No differences were found between the various disorders. Differences were also
found between the subgroups of bilateral masses, where the bilateral nodules group
presented a higher frequency of HGA than the cyst and contralateral reactive nodule.

Abstract: This study was undertaken to better understand current regional opinions regarding vocal fold nodules in adult singers. A questionnaire was sent to 298 persons representing the 3 professional groups most involved with the care of singers with vocal
nodules: otolaryngologists, speech pathologists, and teachers of singing. The question -
naire queried respondents about their level of experience with this problem, and their
beliefs about causative factors, career impact, and optimum treatment. Responses within
and between groups were similar, with differences between groups primarily in the magnitude of positive or negative responses, rather than in the polarity of the responses.
Prevailing opinions included: recognition of causative factors in both singing and speak ing voice practices, optimism about responsiveness to appropriate treatment, enthusi asm for coordinated voice therapy and voice training as first-line treatment, and accept ance of microsurgical management as appropriate treatment if behavioral management
fails.

Abstract: A survey of pediatric otolaryngologists about voice disorders in children sug gests that similar to 1% of children examined were noted to have voice problems, and in
only one fifth of these children (0.2%) were the voice problems related to professional use of the voice, such as singing. Direct flexible laryngoscopy was the sole method of
examination for 80% of the children examined by these pediatric specialists. Voice ther apy for 6 months was generally recommended (88%). The survey represents an estimated clinical experience of > 160,000 children per year, and it achieved a response rate
of 40% of pediatric otolaryngologists (48/120). Results suggest that the use of video and
stroboscopy for examination of the pediatric voice would enhance understanding and assure correct diagnosis and treatment.

This descriptive study was designed to investigate the incidence of self-reported recurrence of symptoms of vocal nodules in adults following voice therapy by a speech-lan guage pathologist, in order to determine the efficacy of the voice therapy received.
Twenty-eight subjects who were between 2 and 130 months post-therapy answered a
questionnaire. Using a chi-square analysis, a relationship was found between (a) the
duration of symptoms prior to therapy and recurrence of symptoms after therapy, (b)
months of therapy and months post-therapy when recurrence of symptoms occurred,
and (c) duration of symptoms prior to therapy and months post-therapy when recurrence
of symptoms occurred. While 19 subjects (68%) reported a recurrence of vocal symptoms following therapy, only seven (25%) experienced vocal symptoms severe enough to
seek additional professional help. Based on these findings, and within the limits of this
study, voice therapy was found to be effective and beneficial.

Caring for the professional singer, whether an operatic performer or serious amateur,
involves careful consideration of both physical and emotional components, as it does in
other performing artists. However, because the head and neck contain representatives of
other major organ systems in close proximity to the phonating larynx, singing is addi tionally vulnerable to a range of diseases of the respiratory, gastrointestinal, and endo crine systems. This review provides an overview of the conditions typically encountered
in singers These include occupational disorders (muscle tension dysphonia, vocal nodules, vocal hemorrhage and polyps, chronic voice deterioration), general health issues
with vocal implications (respiratory diseases, gastric reflux, endocrine problems, medica tion usage), as well as lifestyle considerations.

July
During the 5-year period from 2001 to 2005, 902 patients with vocal fold nodules were
examined and treated at Tokyo Voice Center. In this paper the clinical records of those
patients were studied statistically. The results were as follows. 1. Of the 902 patients,
113 were males and 789 were females. The incidence was higher in males in children
aged 10 and under, and higher in females over age 10. The average age was 32.9. 2.
Seventy percent of the cases were professionalvoice users. 3. In 165 patients treated
by voice therapy alone, the complete remission (CR) rate was 43%. In these CR cases,
average treatment time was 3.1 months. The CR rate was significantly higher in cases
whose duration of hoarseness prior to the first visit was within three months. 4. In 222
patients who underwent steroid therapy, the CR rate was 56%. In these CR cases, average treatment time was 2.8 weeks. 5. Surgical treatments were chosen in 250 cases. Although recurrences were seen in 42%, 74% of those patients obtained CR after additional treatments such as steroid therapy. As 58% had no recurrence, in total 90% of the
surgical patients were doing well. The CR rate was significantly higher in the surgical pa tients than in cases who received any other treatment.

There have been many advances in microsurgery for voice professionals over the last
three decades. Driven by a greater understanding of the anatomy and physiology of
phonation, most of the advances provide greater surgical precision through improved ex posure and more delicate instrumentation. Laryngologists who perform laryngoscopic
surgery should be familiar with the current state-of-the-art and should use the latest
techniques and technology for all voice patients and particularly for voice professionals.

Vocal nodules are structural lesions very common amongst professional voice users
such as teachers. We have studied the risk factors that predispose the development of
vocal nodules in teachers. Two hundred and forty-two teachers were selected: 120 with
vocal nodules and 120 with normal vocal folds.Professional and personal factors as well
as classroom environment were studied. A complete evaluation of the voice was performed, aerodynamic measures, tone and extension of the voice, acoustic analysis, perceptual evaluation of the voice as well as a videolaryngostroboscopy which was definitive
in the diagnosis. Younger teachers with less years of teaching experience a greater have
tendency to develop vocal nodules than the rest. Class-room 's dryness, loudness and
echo are correlated with the pathological group. The most relevant personal factors in
the pathological group were previous vocal pathology, laryngeal surgery, nasal surgery
and gastroesophageal reflux. Vocal intensity and vocal frequency ranks were shorter in
the pathological group. We could also see that, fonatory flow was less effective in the
pathological group.

Patients diagnosed with nodules(NO = 40) in a large university hospital clinic and an
age-stratum matched nondiseased group (ND = 200) described adverse outcomes of vocal impairment on work and work-related communications. NOs were significantly more
likely than NDs to report symptoms of hoarseness (73% vs. 26%), high-note difficulty
(70% vs. 20%), difficulty speaking with a lower voice (53% vs. 13%) and a tired voice
(50% vs. 10%), and their greatest source of physical discomfort was associated with
scratchiness (61% vs. 3%). The average number of symptoms was four in NOs and less
than one in NDs. Nodule patients were most concerned about the effects their voice
problem would have on their future career (78% vs. 24%) and 49% of NOS reported
their voice problem had an adverse work effect in the past compared with 4% of NDs.
Having a voice condition limited current job performance in 39% of the NO group but
only in 2% of the ND group. The results suggest that a diagnosis of nodules plays a ma jor role in disrupting careers and work activities and that available educational programs
and additional research are needed for improving their functional ability and preventing
adverse outcomes in the lives of individuals with voice disorders.

There are more patients with vocal cord nodules in China than in Japan. The occupation
of these patients consists mainly of female singers or teachers. On the basis of the etiology and pathology of Chinese traditional medicine, there are three different treatment
modalities for this disease. Shikunshi-to, Toninsibutsu-to and Zoueki-to. These Chinese
traditional medicine treatment modalities have been characterized by the combined use
of Chinese medical herbs according to each individual patient's status.

Considering epidemiologic, histopathologic, and aerodynamic date, and according to in formation provided by laryngostroboscopic observations, a biomechanical hypothesis accounting for the pathogenesis of vocal nodules is worked out. It is based on a chronic re ciprocal microtrauma of a specific portion of the vocal fold edge. Computer modelling
points out that three conditions are necessary and sufficient for generating such a local ized microtrauma when vocal folds oscillate: oscillation axes of vocal fold edges need to
be slightly bowed; dorsal extremities need to be disjoined; oscillation amplitude needs to
be sufficient: anatomical physiological and behavioral correlates for these three requirements could be found in the structure of the conus elasticus, the hypotony of adductor
and vocalis muscles due to fatigue related to intensive ( professional) voice use, and as
this results in undesirable acoustic changes, a compensatory hyperkinetic phonatory ex piration.

Singers and actors who abuse their voices may develop either polyps, nodules, contact
ulcer, and/or contact granuloma. Rarely a vascular lesion consisting of a hypertrophic
vessel projecting above the medial or superior mucosal surface of the vocal cord is encountered that may contain a small knucklelike deformity. Clinically this is not dissimilar
in appearance to a vessel found on the anterior nasal septum that is responsible for epistaxis. When the voice is strained, these vessels can rupture, causing recurrent submu cosal hemorrhages in the professional voice user. The case described is that of a wellknown actress in whom vocal abuse did not produce a submucosal hemorrhage from the
varix but rather an edematous change and symptoms identical to those of a soft, early
vocal cord nodule.

Vocal cord dysfunction has a definite incidence of association with high environmental
noise levels. The authors' study has shown roughly an 8% incidence of vocal cord dysfunction (vocal cord nodules, vocal cord polyps and chronic laryngitis) in individuals
working in high noise environments. In addition, those individuals who have surgery for
vocal cord nodules and who work in high noise environments will have over a 30% incidence of recurrent vocal cord dysfunction following surgery. The study indicates that females tend to be more at risk in high noise environments than males.

On the basis of experience with the treatment of twenty six patients with singer's
nodes, the most typical and frequently observed clinical signs of the condition are out lined. Emphasis is laid on the role played by the mechanical factor as a contributory
cause. The occupational conditioning of the formation of singer's nodes is underlined. It
is established that among the patients with so-called vocal professions their incidence
amounts to 87.47%. In conclusion it is pointed out that the teaching profession is the
most frequently affected. All the patients are subjected to operation through microlaryn gosurgery, and the results attained are estimated to be very good. Finally, prophylactical
measures are recommeded aimed at preventing the formation of singer's nodes.

Catamnestic evaluations in 763 patients suffering from vocal cord nodules and polyps
show distributions related to age, sex and profession and give materials for critical consideration about therapeutic methods in use. During childhood an active treatment of
nodules remains doubtful, parent counceling should be preferred. In adults a combined
method including microscopical removal of pathological tissue leads to the best results,
provided that the pathological changes have existed for a longer period of time; in other
cases silence followed by voice training can be recommended now as before.

Numerous occupations demand an optimal speaking capacity. If occupational vocal
disorders (occupational dysphonias) occur, these impair interpersonal communication
and professional performance. Vocal disorders in and as a result of vocal professions must be differentiated. In general, an increased frequency of professional dysphonia is to be observed because numerous new occupational groups demand intensive
speech performances. The findings are largely polysymptomatic and may include psycho genic disturbances. Questions of treatment, professional ability and prognosis are discussed.

Singer's nodes are small thickenings localized at the junction of the anterior and middle
thirds of the vocal cords. They are frequent conditions which are not due to inflammation
but to excessive use of the voice. This mechanical factor in straining the voice has a
traumatic effect on the larynx. The prognosis of singer's nodes has been considerably
improved by associating microsurgery with postoperative speech training. Quicker and
better results are attained, with complete recovery of the voice. The intervention is
harmless and can be advised for all forms of nodules of the vocal cords.

Vocal nodules (singer's nodules) are a typical professional disease of the vocal apparatus. This disease occurs more frequently in 20- to 50-year-old singers. The nodules
form because of vascular disorders secondary to overstrain of the vocal apparatus in
phonation and disorders of vegetative innervation. 43 opera singers were treated whose
age and singing history ranged from 22 to 57 years and 3 to 26 years, respectively. The
treatment combined psychotherapy, medicines with phlogenzym as a basic drug, physio -
therapy and phonopedia. Phlogenzym allows to avoid "silence regimen", surgical inter vention. This improves treatment efficacy, shortens the time of disability for singers.

Research and Markets (http://www.researchandmarkets.com/research/c12e3f/germany telecommun) has announced the addition of the "Germany Telecommunications
Report Q4 2010" report to their offering. The Germany Telecommunications Report
provides industry professionals and strategists, corporate analysts, telecommunication
associations, government departments and regulatory bodies with independent forecasts
and competitive intelligence on Germany's telecommunications industry. The latest
quarterly report on Germany's telecoms market includes a comprehensive coverage of
recent developments in the country's mobile, fixed voice and broadband sectors. We
have also included key activities in the cable TV, pay-TV and IPTV markets, along with
regulatory and industry developments across the entire telecoms sector. At the end of
June 2010, German mobile market held about 107.712mn subscribers, reflecting a net
loss of 525,000 subscribers in the second quarter of the year. Market leader T-Mobile was
the main culprit for the third consecutive quarter as it shed 1.568mn subscribers, bring ing the net subscriber loss between Q309 and Q210 to 2.354mn. The operator attributes
the subscriber losses to continued discounting of inactive SIMs and is hopeful of return ing to growth when the process is completed. The three other mobile operators Vodafone
Germany, E Plus and Telefonica O2 Germany all saw very strong net additions in the
quarter. However, all three of them also reported worse subscriber mixes compared to
Q110, implying a vigorous drive at attracting prepaid customers to boost market share.
Mobile operators that acquired spectrum in the 800MHz band in the April 2010 auctions
have started making plans to roll out LTE networks in the country. In July 2010, Voda fone selected equipment manufacturers Huawei Technologies and Ericsson as technology
partners for deploying an LTE network in largely targeted at underserved areas. Vodafone plans to start deploying LTE at the end of September 2010, with around 1,500 base
stations planned to have LTE technology by the end of 2011. In August 2010, FinnishGerman telecoms equipment and solutions vendor Nokia Siemens Networks (NSN) was
selected to provide a pilot LTE network in Halle for O2. Under the contract, NSN will rollout base stations and enhanced packet core (EPC) nodes to provide broadband capacity
and coverage in Halle and its suburb Teutschenthal. The pilot network in Halle will oper ate in the 2.6 GHz band, while the network in Teutschenthal will operate in the 800 MHz
band. The network is expected to go into pre-commercial operation by the end of 2010.
In the fixed-line and broadband markets, Deutsche Telekom and O2 recorded decline to
fixed-line subscriptions as the regulator reported an uptrend in DSL-based VoIP usage.
This aligns with one of our views is that the growing popularity of VoIP services will en hance subscriber losses to traditional fixedline services. However, Deutsche Telekom is
hopeful that the rapid uptake of its IPTV service and the roll of fibre optic broadband to
cover more areas in the country will help stave off the decline in fixed-line services which
will be sold in bundled packages with the more advanced data services. Meanwhile, the
pay-TV sector is set to increased competition as Sky Deutschland has revealed that it is
in talks with leading cable operators and other content distributors to set up content dis tribution partnerships for high demand programs, such as the German football league, in
order to counter the rapid growth of Deutsche Telekoms IPTV service. Key Topics

Philippines' President Aquino III's Inauguration and State of the Nation Address Secured With Firetide Wireless Video Surveillance Network
Telecommunications Weekly, September 1, 2010, p.29
LANGUAGE: English
WORD COUNT: 798
TEXT:
President Benigno Aquino III's inauguration, celebration event and first State of the
Nation Address (SONA) were successfully secured by a rapidly deployed, real-time
Firetide wireless infrastructure mesh network. The temporary video surveillance network
was installed to assist the 5,000 police officers who were deployed in the Metro Manila
area during the inauguration and SONA festivities. The system was installed by Firetide's
leading partner in the Philippines DTSI (Diversified Technology Systems) and used net work cameras from Axis Communications and open-platform video management from
Milestone, both Firetide's technology solution partners. "The National Capital Region Po lice Office (NCRPO) is committed to using state-of-the art technology to improve the ef fectiveness of the police in the Metro Manila area and for special events," said Director
Roberto Rosales of NCRPO. "We chose Firetide for the temporary surveillance network
because we are currently using their mesh network for the video surveillance backbone
infrastructure of the NCRPO Command Center. We knew that their wireless mesh technology would deliver the real-time, high-performance video needed to help keep the President safe." After several weeks of planning, the wireless video surveillance system was
installed by DTSI at the Luneta Grandstand in Manila a day before the June 30 inaugura tion, to monitor the crowd and help provide security for the event. DTSI deployed
Firetide outdoor infrastructure mesh nodes and the Axis network cameras on area light
poles and the stage itself. A mobile command and control vehicle was equipped with
Milestone's video management system and a Samsung monitor to receive real-time
video feeds of the area under surveillance so that the NCRPO could view the activities remotely. After the event, the system was taken down and transported to Quezon City 20
kilometers away to provide security for the night celebration. The entire system was put
up two hours before the start of the party. Over 10,000 people attended the event, with
various locations - stage, backstage, overhead stage, entrances, exits -- monitored by
the video surveillance system. Using the same system, DTSI then provided security for
the first SONA of the President on July 26. Firetide mesh nodes and Axis cameras were
placed strategically to help police monitor a crowd of more than 6,000 people. "In each
instance, we were able to set up and deploy the network and deliver real-time, high-per formance video feeds of key areas to the command center within a matter of hours,"
said Joel Somontina, head of the Information Transport System of DTSI. "To be able to
do this so quickly and easily was amazing." In addition to the temporary network,
Firetide's MIMO infrastructure mesh is currently being used by the Philippine National Po lice as a cost-effective alternative to fiber for backhauling video feeds from disparate se curity installations throughout the metro area. The network aggregates more than 400
security camera feeds and delivers them in real-time to the NCRPO Command Center.
The NCRPO has plans to expand the Metro Manila network and to continue using portable
mesh installations in future events. "Today, Firetide wireless infrastructure mesh techno logy plays an increasingly important role in helping public safety agencies keep citizens
safe," said Bo Larsson, chief executive officer of Firetide. "Nowhere is this safety more
critical than at major events such as the Philippines presidential inauguration and state
of the nation address, involving crowds in the tens of thousands. With its choice of
Firetide for this unique and special deployment, NCRPO has validated that our technology
meets their most critical requirements and sets the standard for reliable, secure and rapidly-deployable wireless video surveillance." About Firetide Inc. Firetide is the leading
provider of wireless infrastructure mesh networks that enable concurrent video, voice,
and data for municipal, public safety, and industrial applications. Firetide provides reli able high performance wireless infrastructure mesh and access solutions for video surveillance, Internet access, public safety networks and temporary networks wherever rapid deployment, mobility and ease of installation are required. Headquartered in Los Ga tos, Calif., Firetide is a privately held company with worldwide product distribution.

TEXT:
IBM (NYSE:IBM) announced that ZON Multimedia, the leader of the pay TV market in
Portugal, has adopted its software to consolidate ZON's IT and network management
into a single view for improved quality and distribution of cable services to its con sumers. The recently signed agreement represents an investment of 1.2 million euros in
the cable operator's strategy to continuously improve customer service. ZON needed an
intelligent network management and IT monitoring solution that could aggregate the
various components of its infrastructure into a centralized view. While IT and networking
have traditionally been managed separately, IBM's integrated service management solutions connect these domains to deliver greater visibility, control and automation to the
enterprise. IBM software can quickly identify and highlight problems in the network, en abling ZON's operational team to plan and schedule maintenance to ensure signal and
distribution quality. The real-time, centralized monitoring of complex networks and IT
domains delivers scalability that exceeds millions of events per day. As a result, ZON will
be able to ensure high levels of customer service as it continues to expand its services
offerings such as HDTV, high-speed internet access, digitalvoice, security, music and
gaming. IBM's holistic approach to ZON's challenge, sophisticated offerings and professional services were key differentiators in winning ZON's preference over competitors
such as HP and replacing HP Network Node Manager with IBM Tivoli Netcool. "A superior
centralized platform for operational management is the foundation to meet ZON's future
technical and business needs more efficiently," said Paulo Ribeiro, board member of ZON
TVCabo, a company from ZON Multimedia group. "IBM software enables our network operations and IT staff to hone in on the most critical problems and even automate the
isolation and resolution of those problems before impacting customers." "Having a single,
real-time view to manage the network can help ZON improve efficiencies and costs associated with maintaining network systems, while delivering consistently high levels of ser vice to customers' homes," said Scott Stainken, general manager, IBM Global Telecommunications Industry. "IBM is pleased to be working with ZON as they exploit the capab ilities of our service management solutions to deliver a differentiated customer experience in their marketplace." ZON will leverage a portfolio of IBM service management
software to automate and integrate its IT and networking systems across the company's
entire infrastructure. This includes Tivoli Netcool and Monitoring, Composite Application
Manager, OMNibus and Network Manager. Keywords: Software, IBM. This article was prepared by Computers, Networks & Communications editors from staff and other reports.

Research and Markets
(http://www.researchandmarkets.com/research/f15b5f/vendor focus rec) has announced
the addition of the "Vendor Focus - Recent IT Developments - Issue 5, 2010" report to
their offering. These Vendor Focus reports keep you up to date on the latest developments in the IT market In this edition, we look at a collection of 9 Vendor Focus - Recent
IT Developments in May 2010 1. CA World 2010 Mainframe Announcements: CustomerDriven Innovation Shapes the Future of Mainframe Management This report centers
around key announcements at CA World 2010 in the application management space. Although there were multiple announcements related to virtualization, Cloud, and main frame, this report centers on the mainframe. It is still the platform of choice for the ma jority of applications running in today's mid- to enterprise-sized companies, and sorely in
need of modernized management products. Today's companies are well-aware that many
mainframe specialists are nearing retirement. The new generation of IT specialists
largely lacks mainframe skills, putting a host of critical applications at risk as baby
boomers retire from the workforce. CA's mainframe-related announcements address this
problem with a collaborative workspace, an installation/maintenance platform that re duces cost of ownership by streamlining tools administration, and a modernized Graphic al User Interface (GUI). EMA sees CA's investments in the mainframe space as being
clear differentiators against competitors who have not invested in updating mainframe
toolsets. Discussions with customers indicate the new products are generating significant
interest within the mainframe community. 2. HP Unifies Network Fault, Availability and
Performance Management with NNMi9 On April 21, 2010, HP Software announced a major upgrade to its network management solutions offerings with the release of Network Node Manager i-Series (NNMi) version 9.0. In parallel, HP released extensions and
enhancements across its full line of NNM Smart Plug In (iSPI) add-on modules, including
the new iSPI Performance for QA. HP also announced the availability of its Automated
Network Management solutions bundle, a combination of products which encompasses
the vast majority of network management functionalities required by todays network engineering and operations practitioners. These new releases represent a major refresh
across HPs network management portfolio with a focus on unifying network fault, avail ability and performance management while extending the solution with new features for
dealing with virtualized infrastructures. 3. Integrating with the Cloud: IBM Acquires Cast
Iron Systems IBM recently announced the acquisition of Cast Iron Systems, an applica tion integration vendor, for an undisclosed sum. The acquired company is a leader in its
respective space and well positioned with a product line spanning physical and virtual ap pliances, as well as the cloud. Cast Iron Systems was one of the first to market with con nectors for cloud-based solutions such as Salesforce.com and RightNow.com. This is
high-demand functionality, since many IT organizations are seeking to integrate cloudbased services with a variety of enterprise applications. EMA sees this as a win for IBM
and one that will provide additional traction in the Small to Medium-sized Business (SMB)
and enterprise cloud markets. However, companies should be aware that this product
does not replace, but rather supplements, traditional Enterprise Application Integration
(EAI) and Enterprise Service Bus (ESB) products. 4. What Terma Labs can Teach the Industry about Business Service Management The role of automation in service management is continuing to rise in importance both with the ascendant interest in Cloud Ser vices and virtualization, and with the growing recognition that automation is central to
enabling and solidifying best practices across domains. Automation does this last in two
respects: it hardens processes into a more consistent workflow, but it also provides ITprofessionals and managers with more time to focus on the dialogs and value-oriented
initiatives that are so central to business-aligned IT services. Within the automation pan theon, Workload Automation (WLA) too often gets marginalized as a fairly well defined
area with roots in job scheduling, despite its pervasiveness and rapid ROI. The need to
place WLA in context with larger automation and service management capabilities is so
far not well understood both by the industry in general, and by many WLA vendors
themselves. This report looks at WLA in that larger context and presents a true service
management vision of what WLA can and should become. The report also introduces
Terma Software Labs JAWS, as the only solution in the market today that meaningfully
bridges that gap, with both an eye to present integrations and future possibilities as a
unifying system for job automation from a service impact perspective. 5. CloudSleuth:
An Independent, Open Approach to Cloud Performance Monitoring In April, 2010, beta
availability was announced for CloudSleuth - an innovative new open community focused
on measuring and reporting the health and performance of cloud service providers.
CloudSleuth has been created as a collaborative platform for developing best practices
around cloud ecosystems while also delivering an independent voice and viewpoint
which can help IT organizations select and monitor providers. The initiative has initially
been conceived and sponsored by Compuware and Gomez (a Compuware subsidiary)
with the stated intent to welcome any practitioners and technology providers who have
an interest in promoting the long-term reliability, predictability, and maturity of cloud

Singers Get a Spring Tune Up With Free Voice Screening at The New York Eye
and Ear Infirmary

MAY 12 - (NewsRx.com) -- A medley of rock 'n rollers, sopranos and musical theater
singers in the New York area received a comprehensive voice check-up and a stroboscopic exam of their vocal cords as part of an annual Voice Screening for Professional Singers, sponsored by The New York Eye and Ear Infirmary and MusiCares, the charitable
arm of the national Recording Academy. The screening program was begun as a meaningful way to observe World Voice Day in New York City, one of the entertainment capitals of the world (see also Allergies). "We found fairly extensive voice problems among
professional singers, which is proof positive there is a large unmet need for vocal
care within the show business community," said Michael Pitman, MD, director of New
York Eye and Ear's Voice & Swallowing Institute. "Vocal folds are a singers' instrument
and livelihood, so getting a comprehensive voice exam is a smart way to ensure a
singing career over the long term," he said. Almost three-quarters of the singers also
complained of allergies (pollen producing trees bloomed early and profusely in the city
this year), and it was striking how few knew which products would be most beneficial or
harmful in treatment of allergies. "Over the counter or prescribed oral allergy medication
can be extremely drying," Dr. Pitman noted. "Professional voice users should protect
their instrument with medications that are targeted at the area of their allergy symptoms without the systemic side effects that can affect their voice." Asked to hit high
and low notes, each singer's vocal fold was simultaneously photographed and recorded during a thorough, half-hour assessment by one of four speech language pathologists. Then, each singer had a private consultation with Dr. Pitman and Amy Lebowitz, a
singing voice specialist, who provided them with a personalized folder of voice care recommendations that included vivid, colorful images of their vocal folds which can be
used as a base line reference for future exams. Also included in eachsinger's take-home
packet was a voice conservation tip sheet, applicable to singers of all stripes. More than
half of the 37 singers who were screened discovered they had vocal problems resulting
from nodules and polyps on their vocal folds, atrophy, muscle tension dysphonia, allergy
or acid reflux. The screening is one of many events held nationally in celebration of
World Voice Day of the American Academy of Otolaryngology -- Head and Neck Surgery
Foundation. KayPentax, a medical instrument company, also helped sponsor the New
York screening The New York Eye and Ear Infirmary, founded in 1820 and the first specialty hospital in the United States, is a teaching affiliate of the New York Medical College
and member of Continuum Health Partners. NYEEI handles approximately 224,500 outpatient visits and performs over 25,000 surgical procedures per year. It has one of the
nation's most extensive eye, ear, nose and throat clinics. Keywords: Allergic Disease, Allergies, Allergy Medicine, Pulmonology, The New York Eye && Ear Infirmary. This article

AT&T Deploys Network Disaster Recovery Resources to Chile to Ensure Business Continuity to Enterprise Customers
Telecommunications Weekly, March 31, 2010, p.218
LANGUAGE: English
WORD COUNT: 393
TEXT:
AT&T* announced that it has deployed Network Disaster Recovery (NDR) resources
to Chile as a preventive measure to ensure business continuity of the AT&T node in Santiago. The action is in response to a series of natural disasters that have affected the
South American country since the devastating earthquake of February 27, which was followed by tsunamis and various aftershocks. The NDR resources include trained managers, engineers and technicians of AT&T's NDR team and a recovery trailer equipped
with high-tech equipment, cables and connections. The professionals have already prepared the equipment on site in Santiago as part of AT&T's comprehensive business continuity plan. While the AT&T Global Network node in Chile is currently operational, AT&T
has deployed the NDR resources so that communications can be restored quickly to customers in the unlikely event of additional disaster-related disruptions to the network.
"Our thoughts and prayers are with the people in Chile who have lost their lives, and
those who are facing the challenges of the natural disasters," said Eduardo Farinelli,
AT&T Business Solutions sales center vice president for South America. "In the quest for
recovery, we are committed to supporting our business customers by providing continuity of international communications with clients, vendors and other stakeholders." During
the last 15 years, AT&T has invested more than $500 million in its NDR program, which
includes specially trained managers, engineers and technicians from across the United
States, as well as a fleet of more than 300 self-contained equipment trailers and support
vehicles that house the same equipment and components as an AT&T data-routing orvoice-switching center. Since 1992, the NDR team has been activated more than a
dozen times in response to disasters, including restoring service after the tornadoes in
Oklahoma in 1999; the September 11 attacks at the World Trade Center in 2001; wildfires in San Diego in 2003 and 2007; Hurricanes Katrina and Rita in 2005; and Hurricanes Gustav, Dolly and Ike in 2008. More information on AT&T's NDR program is available at www.att.com/ndr. *AT&T products and services are provided or offered by subsidiaries and affiliates of AT&T Inc. under the AT&T brand and not by AT&T Inc.

'Efficient and effective extraction of vocal fold vibratory patterns from high-speed digital imaging.' According to recent research published in the Journal of Voice , "High-speed
digital imaging can provide valuable information on disordered voice production in voice
science (see also Digital Imaging). However, the large amounts of high-speed image

"In this paper, a nov el algorithm for automatic image edge detection is proposed to effectively and efficiently process high-speed images of the vocal folds. The method integrates Lagrange in terpolation, differentiation, and Canny edge detection, which allow objective extraction of
aperiodic vocal fold vibratory patterns from large numbers of high-speed digital images.
This method and two other popular algorithms, histogram and active contour, are performed on 10 sets of high-speed video data from excised larynx experiments to compare
their performances in analyzing high-speed images. The accuracy in computing glottal
area and the computation time of these methods are investigated. The results show that

to 90 years. Functional voice disorders were most frequently diagnosed (30%), followed
by vocal fold nodule (15%), and pharyngolaryngeal reflux (9%). The role of age, gender,
and occupation was investigated. Pathologies were significantly more commonin females than in males, representing 63.8% and 36.2% of the population, respectively. Professional voice users accounted for 41% of the workforce population, with teachers as
main subgroup. In professional voice users, functional dysphonia occurred in 41%, vocal fold nodules in 15%, and pharyngolaryngeal reflux in 11%. Our data were compared
with data from other countries. Functional voice disorders were overall the most common cause of voice disorders (except in childhood), followed by vocal fold nod-
ules and pharyngolaryngeal reflux," wrote Houtte E. Van and colleagues, University Hospital, Department of Otolaryngology. The researchers concluded: "Professional voice users accounted for almost one half of the active population, with functional
voice disorders as the main cause of dysphonia." Van and colleagues published their

TEXT:
FEB 15 - (NewsRx.com) -- According to recent research from Lodz, Poland, "The aim
of this study was to investigate the relationship between acoustic analysis and bio psychosocial implications of voice problems, evaluated by the Voice Handicap Index (VHI) (see also Dysphonia). The study comprised 120 female teachers with voice
disorders, evaluated by videolaryngostroboscopy. 60.8% of this group were diagnosed as
having functional dysphonia and 39.2% had dysphonia with benign vocal fold masses
(nodules and polyps)." "The controls consisted of 30 euphonic women. The correlations
between VHI and acousticanalysis were assessed in both groups using the Pearson
correlation coefficient and regression analysis. In teachers, the total VHI score was over
5 times as high as in controls (p < 0.001). Moreover, in teachers, significant positive cor relations were found between the total VHI score and the frequency perturbation parameters and amplitude perturbation parameters when both statistical methods were used.
These acoustic parameters also significantly correlated with the score on the functional
and emotional subscales, but rarely with the physical subscale of the VHI. The study re vealed a significant relationship between the objective voice measurements and the
VHI," wrote E. Niebudekbogusz and colleagues. The researchers concluded: "The results
confirmed that VHI can be a valuable tool for assessing biopsychosocial implications of
occupational dysphonia and should be incorporated in multidimensional voice evalu ation." Niebudekbogusz and colleagues published their study in Folia Phoniatrica Et Logopaedica (Correlation between Acoustic Parameters and Voice Handicap Index in Dysphonic Teachers.

FEB 16 - (NewsRx.com) -- A new study, 'Thoracoscopic esophagectomy for esophageal cancer: feasibility and safety of robotic assistance in the prone position,' is now
available (see also Esophageal Cancer). According to recent research from Seoul, Korea,
"To assess the feasibility and safety of robot-assisted thoracoscopic esophagectomy for
esophageal cancer in the prone position. Twenty-one patients underwent robot-assisted
thoracoscopic esophagectomy in the prone position by a surgical oncologist who had no
prior experience with thoracoscopic esophagectomy." "Hemodynamic and respiratory
parameters were serially recorded to monitor changes in prone positioning. All thoracoscopic procedures were completed with a robot-assisted technique followed by cervical
esophagogastrostomy. R0 resection was achieved in 20 patients (95.2%), and the number of dissected nodes was 38.0 + or -14.2. Robot console time was significantly reduced
from 176.3 + or -12.3 minutes in the initial 6 patients (group 1) to 81.7 + or -16.5
minutes in the latter 15 patients (group 2) (p=.000). In group 2, there was less blood
loss (p=.018), more patients could be extubated in the operating room (p=.004), and
the number of dissected mediastinal nodes tended to be increased (p=.093). There was
no incidence of pneumonia or 90-day mortality. Major complications included ana-
stomotic leakage in 4 patients, vocal cord palsy in 6 patients, and intra-abdominal bleed ing in 1 patient. The prone position led to an elevation of central venous pressure and
mean pulmonary arterial pressure and a decrease in static lung compliance. However,
cardiac index and mean arterial pressure were well maintained with the acceptable range
of partial pressure of arterial oxygen and carbon dioxide. Robotic assistance in the prone
position is technically feasible and safe," wrote D.J. Kim and colleagues, University Col lege. The researchers concluded: "Prone positioning was well tolerated, but preoperative
risk assessment and meticulous anesthetic manipulation should be carried out." Kim and
colleagues published their study in the Journal of Thoracic and Cardiovascular Surgery

Fitch Affirms Qwest's IDR at 'BB'; Maintains Stable Outlook
Investment Weekly News, January 16, 2010, p.99
LANGUAGE: English
WORD COUNT: 1261
TEXT:
Fitch Ratings has affirmed Qwest Communications International, Inc.'s (Qwest) Is suer Default Rating (IDR) at 'BB'. Additionally, Fitch has affirmed the IDRs of Qwest's
wholly owned subsidiaries, including Qwest Corporation (QC) as well as the specific issue
ratings as highlighted below. The Rating Outlook for Qwest and its subsidiaries remains
Stable. Approximately $14.1 billion of debt outstanding as of Sept. 30, 2009 is affected
by Fitch's action. Overall the ratings assigned to Qwest and its subsidiaries incorporate
the scope, scale and relatively consistent cash flow generated by Qwest Corporation's
local exchange business, and the stable operating trends of Qwest's enterprise segment.
Fitch believes that Qwest has sufficient capacity within the current ratings to withstand
the continued pressure on its operating profile due to ongoing competitive, technology
substitution and economic factors. The ratings are supported by Qwest's ability to con tinually enhance operating margins and efficiently invest capital into its physical plant,
positioning the company to generate relatively consistent levels of EBITDA and free cash
flow (defined as cash flow from operations less capital expenditures and dividends). Fitch
continues to believe that Qwest's credit profile is strong within the current ratings cat egory, however, its competitive position is weaker when compared to its regional bell operating company (RBOC) peer group. In Fitch's opinion when compared to its RBOC peer
group, Qwest lacks revenue diversity and revenue growth opportunities, particularly a
strong facilities-based wireless business, that can offset technology, economic and com petitive issues that continue to erode Qwest's land-line business. Qwest's business profile
is more wire-line voice and consumer centric relative to its RBOC peer group. These
businesses arguably are most exposed to competitive and technology threats. The current economic environment - in particular slower housing starts and higher unemploy ment - only exasperate the competitive and wireless substitution threats. Qwest's
primary strategy to address the threats to its consumer wire-line business and to im prove the company's overall competitive position centers on its fiber-to-the-node deployment. As of the end of the third quarter of 2009, Qwest has deployed its fiber-tothe-node platform to approximately 3 million homes within its service area. Going forward Fitch expects Qwest to expand its fiber-to-the-node deployment by 1 million to 1.5
million homes during 2010. While the rate of access line erosion improves in markets
where the fiber-to-the-node has been deployed, the strategy has yet to slow the pace of
revenue erosion within the company's Mass Market business segment. Qwest's Mass
Market segment revenue decline was 7.9% (on a year over year basis and excluding its
wireless business), which ranks highest among its RBOC peer group. Balancing the operational concerns is Fitch's expectation that Qwest will continue to generate relatively
stable amounts of free cash flow as Fitch believes that the company has a sufficient level
of flexibility within its capital budget to manage free cash flow generation. During the
first nine months of 2009, the company generated approximately $1 billion of free cash
flow, marking a significant increase when compared with $426 million of free cash flow
generated during the same period last year. Contributing to the large free cash flow
growth was a 28% year over year reduction in capital expenditures. The weaker economy (slow housing starts) as well as operating efficiencies and cost reductions pro duced the lower capital spending. Looking ahead Fitch expects Qwest will generate ap proximately $1 billion of free cash flow during the ratings horizon. Qwest's liquidity posi tion and overall financial flexibility are strong and are supported by expected free cash
flow generation, cash on hand ($2.1 billion as of Sept. 30, 2009) and available borrowing
capacity from Qwest's new $1.035 billion senior secured revolver, which expires Sept.
30, 2013. Overall, Qwest's capital structure strategy continues to revolve around refinancing the debt maturing at QC while using free cash flow generation to retire Qwest and
Qwest Capital Funding (QCF) scheduled maturities. Importantly, Fitch believes that Qw est management is committed to maintaining QC's strong credit profile. Fitch does not
expect Qwest to increase leverage at QC to fund investments, share repurchases or refinance debt issued at QCF or Qwest. Fitch cautions however, that Qwest's liquidity posi tion and financial flexibility will be put under pressure during the near term as the com pany addresses a total of $4.3 billion of debt scheduled to mature during 2010 and 2011.
The liquidity pressure is mitigated somewhat by Fitch's expectation that Qwest will con tinue to generate meaningful amounts of free cash flow during this timeframe. Addition ally Fitch's concern is further mollified by Qwest's ongoing access to capital markets and
the company's successful renewal of its senior secured revolver. Scheduled maturities
during 2010 total approximately $2.2 billion, including Qwest's 3.5% convertible notes
due 2025 and QC's $500 million term loan. QC's senior note offering in April 2009 removes re-financing risk related to the QC maturity. Fitch expects holders of the convertible notes to exercise a put option on Nov. 15, 2010. Fitch anticipates that Qwest intends
to re-finance the convertible notes during 2010 and to that end issued $550 million of
senior notes in September, leaving a $715 million re-financing risk in 2010. The re-financing risk is back-stopped by borrowing capacity under Qwest's new revolver. Finally Fitch
expects that approximately $403 million of QCF maturities will be retired through free
cash flow generation. Existing cash, coupled with expected free cash flow generation
during 2011 should be sufficient to address $1.3 billion of Qwest and QCF maturities
while $825 million of QC notes are expected to be re-financed. Leverage, as of the latest
12-month (LTM) period ended Sept. 30, 2009, was 3.11 times (x), reflecting a modest
increase of 17 basis points relative to year-end 2008. QC's leverage metric for the LTM
period ended Sept. 30, 2009, increased 23 basis points to 1.76x. From Fitch's perspective Qwest's leverage is somewhat elevated due to two note issuances during 2009 totaling approximately $1.4 billion that are expected to re-finance 2010 scheduled maturities.
Fitch believes that the company's leverage will be approximately 3.2x as of year end
2009. Expected debt reduction during 2010 and 2011 as Qwest and QCF scheduled maturities are retired with existing cash and free cash flow generation provide the impetus
for further improvement of Qwest's credit profile. Assuming the successful refinancing of
the convertible notes, Fitch anticipates that Qwest's leverage will approach 3.0x by year
end 2010 and improve to 2.8x as of year end 2011. The Stable Rating Outlook reflects
Fitch's expectation that the company's operating strategies, in particular the continued
strengthening of Qwest's service bundle and investment in high speed data, will preserve
operating margins and slow the rate of erosion of Qwest's Mass Market operating segment. Operational issues will, in Fitch's opinion have the greatest influence when consid ering negative rating actions. Key among these issues will be Qwest's ability to maintain
or enhance operating margins, continue to generate consistent levels of free cash flow,
and stabilize revenue and access line erosion. While acknowledging a potential strength -
ening of Qwest's credit profile, positive ratings actions would likely be considered as Fitch
observes a persistent trend of positive revenue growth in each of the company's operating segments along with stable operating margins. Keywords: Banking, Capital Markets,

Integrity Networks, LLC: Local Businesses Get New Technologies without Hefty
Capital Expenses
Technology Business Journal, December 8, 2009, p.46

TEXT:
Midwest wholesale voice and data service provider, Integrity Networks has seen a
sizable increase in profits and customers since offering a hosted Ciscovoice solution for
small and medium-size businesses. Looking for ways to help businesses keep current
with technology without making hefty capital expenses, Ben Rife, Integrity president and
CEO, developed a new hosted Cisco voice offering and turned a traditional capital expense (a phone system purchase) into an operating expense. "At the beginning of this
year we were approached by a customer requesting a hosted voice solution, so we
partnered with 123Net to help us build it," said Rife. Midwest wholesale voice and data
service provider, Integrity Networks has seen a sizable increase in profits and customers
since offering a hosted Cisco voice solution for small and medium-size businesses.
iSekurity, one of the nation's largest, most sophisticated fraud detection and resolution
companies relied heavily on two-way communications among its customers, satellite of fices and headquarters in Washington DC. To her embarrassment, iSekurity CEO Sue
Kampe discovered calls coming into the call center were often either missed or
the voice quality was poor. "When you run a business like ours, or any for that matter,
you absolutely need clear, reliable communication and we suffered losses because of the
poor quality. We were referred to Integrity by Cisco and they came up with a viable,
cost-effective solution, resulting in three times better quality. Integrity is a willing and
hardworking partner and they went out on a limb to come up with an innovative, viable
solution and we are looking to them for other technology support," said Kampe. Since of fering hosted voice, Integrity averages five new clients per quarter, an achievement Rife
attributes in part to the customer benefits. "There's no upfront capital expense with our
VoIP solution. We provide an affordable voice solution and support, all for a flat monthly
per phone price. We do away with the confusing telecom billing and iron-clad contracts.
It's not uncommon for us to provide a complete VoIP solution including all hardware and
services for less than what our clients are paying for their telecom circuits alone." said
Rife. About Integrity Established in 2003, Integrity Networks, LLC is a leading provider of
managed services and Cisco Unified Communication Solutions. From its headquarters in
Troy, Michigan, Integrity strives to deliver the best voice and data network solutions
possible, including hosted voice, managed network, managed backup and managed internet services. For more information visit www.IntegrityNet.net or call 248-247-7200.

OAISYS Tracer Delivers Affordable, Enterprise-Class Quality Assurance and
Workforce Optimization
Technology Business Journal, November 24, 2009, p.91
LANGUAGE: English
WORD COUNT: 725
TEXT:
OAISYS(R), a leading provider of call recording and contact center management
solutions, announced the immediate availability of Tracer version 6.0, the industry's lead -
ing digital recording solution for contact centers. Tracer 6.0 delivers new feature enhancements to better support large-scale, enterprisewide deployment of the award-winning Tracer professional interaction management solution. Tracer's live call and auto
call monitoring functionality, as well as improved agent coaching and evaluation features,
reduce training costs and increase revenue, driving overall profitability for contact cen ters. "OAISYS provides enterprise users with the tools they need to effectively address
their customer service objectives, regulatory compliance requirements and unique business challenges throughout the entire enterprise," said Brian Spencer, president of
OAISYS. "The feature enhancements in this latest release of Tracer were driven by the
direct feedback of our contact center customers. Our willingness to listen and actively re spond to the voice of our customers with innovative, reliable and affordable solutions
helps them to achieve low-cost, efficient and profitable contact center operations." Tracer
utilizes patent-pending OAISYS Portable VoiceDocument (PVD(TM)) technology to capture telephone-based interactions as digital call recordings, or voice documents, that are
available to store, organize, play back, annotate and share with others as needed. This
core PVD functionality is paired with Tracer's advanced contact center management features, including employee performance evaluations, the ability to live monitor calls and
generate quality and resource utilization reporting. Now, customers can experience even
greater ease of use along with new, unique and powerful capabilities that improve upon
the robust Tracer feature set. New Tracer feature enhancements include: Live Call Monitor: Tracer's integrated Live Call Monitor feature allows users to connect to one or more
Tracer systems, each with up to 192 channels, to easily and efficiently monitor agent in teractions with customers in real time. Benefits include easy monitoring access to calls
occurring across all nodes of the enterprisevoice network, such as those handled in a
remote or branch office. Auto Call Monitor: Tracer's Auto Call Monitor feature provides
real-time automatic live monitoring of calls meeting criteria predefined by management.
Supervisors may begin hearing a call that meets desired conditions instantly, or they can
receive an immediate visual and/or audible notification of a situation requiring their at tention. For instance, an agent call with an upset customer can be identified and resolved
before resulting in potentially negative and costly consequences. Live Annotations and
Coaching: Tracer's live annotations and coaching capabilities enable supervisors to add
text annotations directly to calls during live monitoring, permitting their observations to
be captured in real time. Integrated instant messaging lets supervisors coach agents dir ectly and unobtrusively, allowing them to influence the quality of interactions. All annota tions and coaching sessions are logged in context with the voice recording, providing an
easy way to reconstruct contact center scenarios. Quality Control Work Queues: Tracer's
quality control work queues allow users to create rules for the count and types of calls
that supervisors must evaluate. This improves the speed and efficiency with which agent
evaluations are completed, while also ensuring supervisor objectivity. Automated Call Or ganization: Tracer's automated call organization feature identifies calls that meet set cri teria based on call filters, such as agent ID or extension lists, and categorizes them with in a specific search folder, which streamlines performance evaluation. For example, a
manager can easily review a folder comprised of only his or her sales agents' calls.
Owner's Report: Tracer's Owner's Report feature clearly reveals who is using Tracer, how
often and for what purpose. This enables organizations to hold management accountable
to their contact center oversight and quality assurance responsibilities. The OAISYS
Tracer solution is widely used by organizations throughout a broad range of industries to
obtain greater insight and understanding into the interactions that shape their everyday
operations. These industries include financial services, healthcare, automotive dealer ships and, within the public sector, transportation, energy and government agencies.
Businesses use this information to ensure regulatory compliance, support customer retention and promote revenue protection. Keywords: OAISYS, Technology, Data Management, Software, Audio and Video, Telecommunications, VoIP,Professional Services, ,

Italtel and ECI Telecom Sign a Partnership for the Supply of Advanced Telecom
Solutions for Service Providers Worldwide
Network Weekly News, November 23, 2009, p.49
LANGUAGE: English
WORD COUNT: 1189
TEXT:
Italtel, one of the leading companies in the next generation IP networks sector, and
ECI Telecom, global provider of networking infrastructure solutions optimized for nextgeneration network (NGN) migration, announced that they have signed a partnership
agreement for the sale and customization of optical transport systems for metropolitan
networks and access platforms for voice, data, IP video and fixed/mobile convergence.
As such, Italtel will be a preferred vendor and system integrator for ECI Telecom technology in the building of integrated communication networks for service providers, commu nications providers and utility companies in the "Quadruple Play" (data, voice, video,
mobile) access and transport markets. Under this agreement, Italtel has become one of
ECI's Global Partners. "As the telecom sector continues to evolve, strategic partnerships
such as this new agreement between ECI Telecom and Italtel, will be critical for the suc cess of telecom equipment suppliers, especially in an increasingly competitive and ma ture market. ECI brings a best-in-class Access platform in the Hi-FOCuS portfolio and a
leading multi-service transport platform in the XDM, while Italtel brings an impressive
presence in EMEA and Latin America, as well as valuable expertise in system integra tion, voice over IP and mobility. This partnership makes perfect business and technology
sense," said Erik M. Keith, Principal Analyst for Broadband Infrastructure at Current Ana lysis. "The partnership with Italtel strengthens our presence in important and growing in ternational markets. With our access and transport portfolio, Italtel will be able to
provide their customers with high-end platforms that are optimized for next-generation
evolution. In Italtel, we have found a partner with the required ability and expertise that
are complementary to our own, in addition to a strong and recognised specialisation in
system integration," noted Tony Scarfo, Head of Global Channel Sales, and Partners of
ECI Telecom. "The agreement with ECI is part of our plan to develop into specific foreign
markets and to widen the perimeter of our products and services," commented Claudio
Chiarenza, Head of Planning, Marketing & Business Development of Italtel. "This partner ship allows us to extend our portfolio of solutions for service providers in the EMEA and
Latin America markets with products for access and optical transport, and to adopt a
structured approach to a market segment that is potentially attractive, represented by
European service providers and utilities with their own network infrastructure." The partnership between Italtel and ECI Telecom will cover the integration and customisation, at
the customers' premises, of ECI's Multi-Service Access Node (MSAN) Hi-FOCuS(TM), and
the metro edge BroadGate(R) line of products. The Hi-FOCuS supports voice, data and
video over one, converged IP platform, while the BroadGate line is an advanced multi-service provisioning platform for the transporting of data streams over fibre optic in
metropolitan networks. Market Background Despite the economic downturn, which
caused capex to decline in 2009, with service providers putting on hold some of their
major infrastructure investments, the telecom market still remains one of the most dy namic and competitive sectors in today's world, as subscribers and network traffic keep
growing. Service providers face many challenges - the need to migrate to IP networks,
the blurring of boundaries between different types of providers, the demand for advanced services, in addition to lower margins, reduced revenues and increased competition. According to Infonetics Research, service providers today are transforming into vertically integrated multimedia providers. Infonetics expects broadband and corporate
traffic to continue to grow, as IP video, IPTV and personalization of services take hold.
IPTV traffic patterns will cause a continual push for more network capacity over the
years. There is increased adoption of broadband data services and of mobile telephony
and data traffic. "Worldwide, we expect over 600M fixed broadband subscribers in 2013.
Much of this growth is coming from emerging markets, such as China, Southeast Asia,
and Russia, as more mature markets in Japan, Korea, North America and Western
Europe reach saturation," said Michael Howard, Principal Analyst, Infonetics Research.
"Subscribers are attracted to new services brought on by broadband investment in IP
video, including IPTV, broadcast TV, video-on-demand, HDTV, network PVR, online gam ing, music downloads, video telephony, and home automation and security services."
Worldwide telco IPTV subscribers reached 26M in CY08 and are expected to grow to
155M by CY13, as operators rely on video services to increase ARPU and to retain fixed
broadband subscribers. Fixed broadband services have some of the highest margins of
any services offered, which is why layering on "sticky" services like IPTV is so critical to
their bundling efforts. Links High-resolution graphics are available for download at flickr. com/photos/ecitelecom Follow ECI Telecom news updates on Twitter at

Unisys Solutions for Latest Microsoft Software Boost Clients' Productivity Options - from Data Centers to Mobile Offices
Information Technology Business, November 24, 2009, p.48
LANGUAGE: English
WORD COUNT: 1159
TEXT:
Unisys Corporation (NYSE:UIS) announced at the Microsoft TechEd Europe conference that it is providing multiple services-based solutions for the new Microsoft Windows
7, Microsoft Windows Server 2008 R2 and Microsoft Exchange Server 2010 environments. The solutions include data center transformation solutions whose value is demon strated by Unisys proof-point tests, as well as end-user services and a unified communic ations service that Unisys is hosting for Microsoft Corp. "When Microsoft delivers software innovations, Unisys is there with innovative solutions that help clients realize the
full value of the products," said Colin Lacey, vice president, Systems and Storage,
Unisys. "We're doing that again for these latest Microsoft offerings to help users improve
their operations and make their people better able to do business anywhere at any
time." These Unisys solutions are designed to help enterprises boost information workers' productivity no matter where they are or how they work, improve the IT infrastructure so it supports business more efficiently, and reduce the costs of IT service delivery
and support. "Unisys deep understanding of both data centers and end-user experiences
adds an extra dimension that helps Microsoft customers realize new efficiencies in computing across the enterprise," said Betsy Frost, general manager, UC Marketing Management at Microsoft Corp. "We are impressed at the range and depth of solutions that
Unisys is offering to support Microsoft Windows 7, Microsoft Windows Server 2008 R2
and Microsoft Exchange Server 2010." Tests Show that Unisys Data Center Transformation Solutions Boost Windows Server 2008 R2 Unisys builds on expertise and best practices in virtualized infrastructure - especially through Unisys Data Center Transformation
Services, Infrastructure Management Suite of solutions, and family of Enterprise Servers
- to help clients use Windows Server 2008 R2 to transform their data centers for greater
efficiency at lower cost. Unisys recently conducted proof-point tests that demonstrate the
power of Windows Server 2008 R2 in a virtualized environment. In the first test, Unisys
demonstrated that the Unisys ES7000 Model 7600R Enterprise Server provides a powerful platform for Microsoft SQL Server 2008 R2 database consolidation. Using Windows
Server 2008 R2 Datacenter Edition, a single Unisys ES7000 server supported the same
workload as 32 dual-socket quad-core commodity servers, each running two 85-gigabyte
SQL Server 2008 R2 databases, while providing better response times. Unisys achieved
those results while quadrupling the utilization rate of the commodity servers and using
55 percent less power. The 32:1 consolidation ratio shows that Unisys can help clients
configure and manage their SQL Server database infrastructure more efficiently and significantly reduce their facilities, server maintenance and support costs. In the second
proof-point test, Unisys demonstrated high availability for virtualized SQL Server 2008
R2 workloads delivered through the new Live Migration capability of Microsoft Hyper-V. In
the past, clients' inability to move virtual machines (VMs) from one host to another
without any perceived downtime or service interruption - a capability especially import ant in large-scale clustered SQL Server environments - has been a key barrier to virtualizing SQL Server workloads with Hyper-V. Unisys solved this challenge with the Hyper-V
Live Migration capability. Unisys migrated 12 VMs, with each running two 85-gigabyte
databases in a single instance of SQL Server 2008 R2 with 20 concurrent users, between
two nodes of an ES7000 Model 7600R clustered server. During the Live Migration process, users experienced virtually no loss of performance or interruption of service. A
third test supported the Unisys decision framework that helps clients make the right vir tualization choices for their environment. Unisys demonstrated the significant perform ance and total-cost-of-ownership (TCO) advantages delivered by Hyper-V. The proofpoint test revealed that a 12-socket Unisys ES7000 Model 7600R can support 384 VMs the maximum currently supported under Windows Server 2008 R2 - with a three-year
TCO per VM of $578. In contrast, a two-socket server using the latest generation of Intel
processors could support only 16 VMs at a far higher three-year TCO per VM of $2,035.
End-User Services Extend Benefits of Exchange Server 2010 and Windows 7 Unisys EndUser Productivity Services enable IT organizations to realize the full business potential of
Exchange Server 2010 and Windows 7. These services provide multiple options for end
users to securely access key productivity environments - whether running centrally managed applications locally on mobile devices such as netbooks and smartphones, access ing them through cloud-based services or using a mixture of delivery options. For ex ample, users of Exchange Server 2010 can benefit from Unisys Unified Communications
as a Service (UCaaS), which delivers Microsoft Exchange, Microsoft Office SharePoint
Server and Microsoft Office Communicator applications in a multi-tenant environment
through Unisys Secure Cloud Solution. In addition, Unisys provides migration and man agement support for Windows 7 to help clients deploy the new environment most efficiently and effectively. Also, the advanced desktop management, support and flexible ap plications delivery capabilities of Unisys End-User Productivity Services give Windows 7
users anywhere, anytime access to their critical productivity environments. Unified Com munications Solutions Help End-Users Explore the Possibilities Based on Unisys expertise
in managed services, Microsoft has selected Unisys to build and manage the Microsoft
Unified Communications Virtual Experience for Exchange Server 2010 and Office Communications Server 2007 R2. This cloud-based trial service enables enterprise users to
try, free of charge, the latest Microsoft UC technology. The service gives organizations
worldwide the opportunity to test key new features of the Microsoft offerings, such as
multi-party instant messaging and voice and video conferencing, and evaluate the potential benefits of Microsoft unified communications for their business. It also helps them
assess how they can help employees collaborate more productively using the devices and
technologies that best suit their work styles - whether PCs, web browsers or mobile
phones. Organizations interested in participating in a 60-day virtual experience should

Tecore Integrates 3G RNC Into iCore, Lowering Rural Operators' Cost of Entry
To UMTS
Network Business Weekly, October 26, 2009, p.36
LANGUAGE: English
WORD COUNT: 604
TEXT:
Tecore Networks, a global supplier of multi-technology 2G, 3G and 4G mobile network infrastructure, announced the evolution of iCore(R), its all-IP multi-technology core
network, with the integration of a 3G Radio Network Controller (RNC). Together with the
iCore UMTS Mobile Switching Center (UMSC) and Home Subscriber Server (HSS), the
RNC enhances support for 3G services and further streamlines the smallest multi-technology network-in-a-box in the industry. Rural and emerging mobile network operators can
optimize total cost of ownership by avoiding the expense of separate RNCs, and supporting multi-vendor radio access networks from one core network. These operators can utilize Tier-1 3G NodeBs with iCore for their RNC and core network elements. iCore is a scal-
able, all-IP core network platform capable of supporting 2G GSM and CDMA and 3G networks simultaneously. Tecore has adopted 3GPP for 3G and 4G infrastructure due to the
robustness of end-to-end transport via IP, the introduction of the IP Multimedia Subsys tem (IMS) core network, and support for multiple access technologies, all of which have
been principal features of Tecore's current architecture. The RNC controls the NodeBs,
performs radio resource management, handles security functions and admission control,
and delivers voice traffic to the media gateway and data traffic to the Serving GPRS
Support Node (SGSN). Tecore's RNC is compliant with 3GPP releases 5, 6 and 7, for an
IP-centric solution with interfaces to a range of other vendors' NodeBs. Given the continuing dominance of voice traffic compared to data, the iCore's capability to
switch voice traffic in a centralized manner represents a significant network cost saving
for the operator. Although rural and emerging mobile network operators lagged the national carriers in deploying 3G services, the industry is moving swiftly to catch up. These
operators need a lower threshold of investment, the ability to scale the network with the
subscriber base, and a built-in path to 4G. Tecore provides the optimal solution by en abling UMTS on a multi-technology core network that can bridge protocols and genera tions. Tecore is currently conducting interoperability testing with RAN vendors, and is in viting others to participate as well. Interested vendors should contact Tecore at [email protected]. "Tecore helped the rural and emerging cellular market get off the
ground by giving operators a compliant alternative beyond the large-scale infrastructure
offerings, and our announcement today demonstrates our continued commitment to this
market," said Jay Salkini, President and Chief Executive Officer of Tecore Networks. "Now
that rural and emerging operators are accelerating their 3G deployment plans, we offer a
proven network platform supporting UMTS and beyond." About Tecore Networks Tecore
Networks is a global supplier of multi-technology 2G, 3G and 4G mobile network infrastructure. Built with the same standards-based voice and data technologies available to
global carriers on an IP-based architecture, we have dramatically enhanced functionality
while minimizing space requirements, installation time and cost of ownership. We also
offer integrated value-added features to enable our customers to increase ARPU and retention. Our solutions include core as well as radio access network infrastructure, supported by state-of-the-art professionalservices. Founded in 1991, Tecore is ISO

TEXT:
Vertical Communications, a leading provider of next-generation IP-based phone sys tems and voice applications, announced the release of three new voiceapplications Wave Contact Center, WaveNet and Wave Call Classifier - available as a software upgrade
on its award winning Wave IP 2500TM and Wave IP 500 TM Business Communications
Systems, the industry's first comprehensive IP PBX with the unique Applications InsideTM
architecture. "Today's release illustrates the power of Wave IP's Applications Inside architecture - the ability to deliver high-value voice applications integrated with VoIP telephony as a single system, and made available as a software upgrade," said Peter Bailey,
Senior Vice President Product Management and Business Development for Vertical Communications. "Wave IP offers customers a full portfolio of voice applications that can enhance business operations, increase productivity through best practices, and drive sav ings in operational and management costs. As a fully integrated "on-the-box" solution,
these capabilities do not require any additional infrastructure investment and can be de ployed and managed through Wave IP's Global Administrator console. With the addition
of a Wave Contact Center agent license, a customer service or accounts receivable employee can be transformed into a full-scale call center agent and realize an increase in
productivity as well as quality of customer service. With the addition of a WaveNet li cense, users across multiple Wave IP sites can easily connect and collaborate, while sys tem administrators can add and intelligently network sites with a few simple mouse
clicks." The Wave IP Business Communications System is a comprehensive IP business
phone system family designed for enterprises of all sizes. Cost-sensitive small- to medi um-sized businesses, and larger distributed organizations seeking to reduce overhead
associated with managing business communications can easily transform their legacy
telephony infrastructure into an application-rich, next-generation VoIP solution by de ploying Wave IP. As a fully integrated solution, Wave IP offers customers ultimate flexibil ity and features - unified communications, contact center, call recording, reporting, net working, management, custom call routing applications and IVR - in a single system.
"We have been using Wave Contact Center in our customer service department for the
last three months, the applications are just great and very easy to configure. In fact, it
took less than 20 minutes for our customer service queues, agents, in queue announcements and call recording to be setup and in production," said Chet Lytle, Jr., President,
Communications Diversified, Inc. "The full integration of Wave Contact Center with View Point allowed our supervisors to access real-time queue and agent information instantly.
Wave Contact Center Reporter provides a broad range of historical reports, again, conveniently from within ViewPoint. The ability to create any desired custom reports utilizing
Crystal Reports is an added bonus. Wave Contact Center is a winner!" "Using Vertical's
WaveNet application we where able to quickly convert the discreet Wave IP systems in
our network into one single communications system. Doing so was a very seamless exercise using the Wave Global Administrator and was accomplished through just a few
simple mouse clicks! With WaveNet, our users can now call other users on a different
Wave IP system as if they are on the same system. Using ViewPoint we can now see the
status of different users all across the network. WaveNet is a great addition to the suite
of applications on the Wave IP system," said Matt Tesdell, Vice President, Tesdell Electric
Ltd. New Applications: WaveNet WaveNet creates an enterprise-wide Wave IP-PBX infrastructure that streamlines all aspects of administration and enables your organization to
operate more efficiently. WaveNet aggregates multiple locations into a single telephone
system, combining users from various locations to present a single network wide extension list and dial plan. Employees everywhere can reach each other through seamless intercom dialing, view presence & personal status (via phone or ViewPoint) and seamlessly
exchange voice mails without the need to remember location or complicated dialing
codes. WaveNet dramatically simplifies administration by eliminating repetitive manual
tasks. Adding a node or changing a user on the network only takes a few mouse clicks
as WaveNet automatically handles the configuration, dial plan synchronization, inter-site
call routing and ongoing management tasks to keep all systems synchronized. Depend ing on system configuration and site preferences, WaveNet can route enterprise calls using either SIP over a VoIP network or traditional PSTN via PRI or Analog for maximum
flexibility. WaveNet uses a peer-to-peer architecture to eliminate any single points of fail ure - this enables offices to continue to function even if intra-office networks are inter rupted, or if an individual location loses power. Robust error recovery and fault management mechanisms built into WaveNet ensures that information such as voicemail, pres ence status etc are automatically cached and synchronized when network connectivity is
reestablished. WaveNet is certified to support networking of up to 100 Wave IP nodes.
Wave Contact Center Traditionally, small to medium size business in need of contact cen ter functionality have had to make a choice between expensive full featured solutions or
compromise for less sophisticated ACD functionality. Wave Contact Center changes the
game by providing robust enterprise class contact center management functionality at
marginal incremental cost. Leveraging Vertical's Applications Inside architecture, Wave
Contact Center runs "on-the-box" and thereby eliminates need for any additional hardware or complex integration. Unlike other contact center solutions that require custom
scripting, programming or complex flowchart design, Wave Contact Center lets adminis trators control all aspects of contact center management including queue management,
routing, agents, supervisors, tracking, and reporting with a simple point and click unified
interface. For example, with a few mouse clicks you can choose how calls in a queue are
distributed to agents, customize the callers' hold experience by playing single or repeat ing messages, prompt callers to enter data, configure call priority, setup automatic call
routing and more. It's just as easy to move, add and change agents, setup and change
agent or supervisor permissions, grant permissions to individuals or groups, record hold
prompts, change routing, manage the queue's voice mail or take the queue off-line.
Calls can be distributed within queues based on various key attributes such as time of
day, longest idle agent, least busy agent etc along with some advanced routing models
such as agent cost or agent skills based routing, priority queuing based on caller etc traditionally available in higher end contact center solutions. Wave Contact Center seam lessly integrates with Vertical's award winning desktop call management application,
ViewPoint, to provide a single intuitive interface for agents and supervisors alike to man age calls and monitor performance. Using ViewPoint, supervisors can monitor queues,
coach agents, monitor real-time metrics and service levels and optimize overall contact
center performance. Wave Contact Center comes built in with a reporter that provides a
powerful set of reports (over 35 distinct reports) that are designed to keep supervisors
and managers informed on key performance metrics and allow them to spot trends in
queue and agent performance. Wave Contact Center is certified to support 100 call center agents. Wave Call Classifier Wave Call Classifier empowers organizations to dramatically improve their customer service and competitive advantage with advanced call rout ing based on real-time lookup of customer data. Serviceprofessionals using Wave Call
Classifier are informed about the caller and the origin of the lead source or relevant promotion before they answer a call. Wave Call Classifier can provide agents with detailed
caller information from any ODBC database (local or external), and intelligently route
calls based on who is calling and what they are calling about.

JAN 26 - (NewsRx.com& NewsRx.net) -- "of review Since the introduction of endolaryngeal microsurgery, several basic microsurgical techniques have been described for
the removal of benign vocal fold lesions (see also Surgical Technologies). These techniques include conventional incision or dissection, bimanual retraction and cutting, mi croflap technique and the CO2 laser," scientists in Kaohsiung, Taiwan report. "Until re cently, only a few microsurgical methods have emerged as new choices for the treatment
of benign vocal fold lesions. This article introduces an innovative method that can pre cisely remove benign sessile vocal fold lesions with epithelial keratosis or hyperplasia
without jeopardizing the intermediate or deep layer of the lamina propria. Recent findings Instead of using conventional vertically opening microinstruments, this microsurgic al pressing excision technique (MPET) utilized two pairs of custom-made horizontally leftopening or right-opening, curved microscissors/curved cupped microforceps to remove
right or left vocal fold lesions accordingly. Using one instrument at a time, the lesion was
subsequently removed with the microscissors and microforceps in a press-evert-cut
manner. Among a total of 553 cases, the treatment results were satisfactory, with 520
(94%) patients retaining a satisfactory/normal (GO) voice 2 months postoperatively.
More importantly, no patient's voice was worse postoperatively. This technique has several advantages: utilizing one instrument at a time can maximize exposure of the narrow endoscopic view, adjusting the pressing force makes precise excision easy in a well
controlled horizontal plane. The MPET is particularly useful for removing sessile vocal
nodules (especially those with epithelial keratosis), epithelial hyperplasia and leukoplakia
in patients with difficult endolaryngeal exposure," wrote K.W. Lee and colleagues, Kaohsiung Medical University Hospital. The researchers concluded: "This could be a well tol erated and precise microsurgical technique." Lee and colleagues published their study in

JAN 26 - (NewsRx.com& NewsRx.net) -- According to a study from Taiwan, "Of review Innovative otolaryngologists speech language pathologists and voice scientists have
continued to move forward in understanding the etiology and treatment of vocal nodules
(see also Surgical Technologies). The presentarticle reviews the publications with respect to the advances in this area." "Recent findings There is support for the notion that
there is a positive relationship between vocal nodules and the presence of a posterior
glottic chink (PGC). Generalized tension in all the laryngeal muscle is often associated with the PGC due to persistent posterior cricoarytenoid muscle pull during phona tion. This phenomenon leads to secondary mucosal change with formation of vocal nodules. Fat augmentation after microsurgical removal of vocal nodules can reduce both the
occurrence of a PGC and posterior cricoarytenoid muscle activity and subsequently
decrease vocal nodule recurrence. Therefore, the treatment efficiency and protocol are
direct and fast. Finally, long-term outcomes studies havedemonstrated improvements in vocal disability with both objective and subjective evaluation," wrote M.W.
Hsiung and colleagues. The researchers concluded: "Fat augmentation is an effective
autogenous implant which may be considered in the management of patients after mi crosurgical removal of nodules."

JAN 26 - (NewsRx.com& NewsRx.net) -- In this recent article published in the journal Otolaryngology - Head and Neck Surgery , scientists in Milan, Italy conducted a study
"To evaluate the correlation between the Voice Handicap Index (VHI) and objective
voice measurements in patients with dysphonia ofdifferent origin (see also Dysphonia). Cross-sectional survey. Otolaryngology department in a university hospital."
"One hundred fifteen patients consulting for voice disorders were enrolled in the study:
32 presented with functional dysphonia (Group 1), 24 with unilateral vocal fold paralysis
(Group 2), 30 with structural dysphonia (Group 3), and 29 with nodules (Group 4).
From each patient, the maximum phonation time (MPT) and a voice spectrogram were
obtained: patientswith type I signal underwent perturbation analysis. Each patient completed the VHI. No significant difference across the four groups, in the VHI scores and
voice measurements, was found. The correlation between the different voice measurements was good, while those between the VHI domains were very good. Considering
the patients with type I signal (n = 80) all together, the correlations between VHI and
voice laboratory measurements ranged between poor and good. Analyzing each patient
group separately, good correlations were found between MPT and functional and physical
VHI domain in Group I (r = 0.58 and 0.68), jitter and functional VHI domain in Group 2

have developed a novel method of gasless endoscopic thyroidectomy via an axillary ap proach," scientists in Seoul, South Korea report. "The present report describes the technique of this method, and analyzes its surgical outcome. Between Nov. 2001 and Dec.
2007 (actual operation period was 50 months), 581 patients with thyroid tumors underwent gasless endoscopic thyroidectomy via an axillary approach. The clinical and patho logic characteristics of patients, operation type, operation time, post operative hospital
stay and post operative complications were analyzed retrospectively. Among the 5 8 1
patients, 171 patients had benign tumor and 410 patients had malignant tumor. There
was no conversion to open Surgery. The operating time and the length of post-operative
hospital stay were 129.4 +/- 51.3 minutes, 3.3 +/- 1.7 days in benign tumor, and 135.5
+/- 47 minutes, 3.4 +/- 0.9 days in malignant tumors, respectively. The tumor size was
2.7 +/- 1.2 cm in benign tumor and 0.78 +/- 0.5 cm in malignancy. Central compart ment lymph node metastasis was found in 112 (27.3%) patients and lateral neck lymph
node metastasis in 13 (3.1%) patients. As post-operative complications, transient hypo calcemia occurred in 19 patients and transient hoarseness was in 13 patients and permanent vocal cord palsy occurred in 2 patients. In the TNM stage, 366 (89.2%) patients

Electrophysiological examination (laryngeal electromyography) was used to differen tiate between the two types of nerve injury. Vocal fold motions were monitored by repeated laryngoscopy during the study period (up to 6 months). Three of the pa-
tients with axonal injury were treated with the regeneration-promoting agent nimodipine. The patients with conduction block all recovered normal vocal fold motion,
whereas patients with axonal injury within the nerve had a significantly worse Outcome.
The 3 patients who were treated with nimodipine all recovered normal or near-normal
vocal fold mobility despite the more severe axonal injury. In contrast to previous reports,
our results show that laryngeal electromyography is a reliable tool for diagnosing nosing the type of injury within the injured RLN, making it possible to predict the functional
outcome in these patients," wrote J. Hydman and colleagues, Karolinska University. The
researchers concluded: "On the basis of the results, a future randomized study on nimodipine treatment for RLN axonal injury is suggested.." Hydman and colleagues pub lished their study in

9 JUL 14 - (NewsRx.com & NewsRx.net) -- "Positron emission tomography with 18Ffluorodeoxyglucose ((18)FDG) has been increasingly used in the diagnostic investigation
of patients with neoplasms of the head and neck (see also Thyroid Cancer). Positron
emission tomography and computed tomography have also proven useful for surveillance
of thyroid cancers that no longer concentrate radioiodine," researchers in the United
States report. "However, certain benign or inflammatory lesions can also accumulate
18F-fluorodeoxyglucose and lead to misdiagnosis. We review and discuss the pitfalls of
using positron emission tomography and computed tomography for surveillance of
thyroid cancer. We present the case of a 48-year-old woman who was diagnosed with a
laryngeal neoplasm on integrated positron emission tomography and computed tomo graphy scanning, after a routine ultrasound demonstrated an enlarged thyroid nodule.
On physical examination, she had a laryngeal mass overlying an immobile vocal fold. The
mass was biopsied and found to harbour a Teflon granuloma. Positron emission tomography positive Teflon granulomas have previously been reported in the nasopharynx
and vocal folds, and should be considered in the differential diagnosis of patients who
have undergone prior surgery involving Teflon injection," wrote M.P. Ondik and colleagues. The researchers concluded: "It is important for otolaryngologists and radiologists to recognise potential causes of false positive positron emission tomography and
computed tomography findings, including Teflon granulomas.." Ondik and colleagues

9 JUN 23 - (NewsRx.com & NewsRx.net) -- According to recent research from Yvoir,
Belgium, "There has been an ongoing confusion among pathologists in their attempt to
accurately identify lesions of Reinke's space (see also Voice Disorders). Nodules, polyps
and Reinke's edema fall in the same basket and differentiation between them relies largely on the clinical description of the pathologic specimen by the operating surgeon than on their distinct pathologic features." "By revising the pertinent literature, the
need for an establishment of the aforementioned term still remains and is further
stressed out, as confusion among the various pathologic descriptions of these lesions still
exists. This is further verified by a study conducted in the Department of Otorhino laryngology-Head and Neck Surgery of the University Hospital of Louvain at MontGodinne, Belgium, involving 323 operative specimens obtained from 200 patients with
macroscopic picture. Statistical analysis showed lack of agreement between surgical and
histopathologic diagnosis in almost a third of the cases (Cohen's kappa coefficient of
0.683 +/- A 0.037, P< 0.001). We, therefore, propose the term ''exudative lesions of
Reinke's space'' to include Reinke's edema, polyps and nodules," wrote A. Hantzakos and
colleagues. The researchers concluded: "These lesions share common histologic features,
which are located in the Reinke's space and whose macroscopic appearance is largely
dependent upon the presence and duration of certain causative factors." Hantzakos and

9 JUN 22 - (NewsRx.com & NewsRx.net) -- According to a study from Shanghai,
People's Republic of China, "Phonation threshold flow (PTF) may provide a tool to assess
laryngeal function and could differentiate between normal and pathological voices (see
also Polyps). Both polyps and nodules contribute to an increased PTF by creating an in complete glottal closure and increased vocal fold mass and thickness. Prospective
study." "The Kay Elemetrics Phonatory Aerodynamic System (PAS) (Kay Elemetrics Corp.,
Lincoln Park, NJ) was used to collect mean flow rate (MFR) and PTF measurements from
40 normal subjects, 21 patients with vocal fold nodules, and 23 patients with vocal fold
polyps. Gender-based differences were assessed using a t test. The effect of vocal
pathology on PTF and MFR was determined with an ANOVA. Diagnostic potential was
evaluated using a receiver operation characteristics (ROC) analysis. Both PTF (P = .
047) and MFR (P = .008) were significantly affected by gender. Using a two-way ANOVA
and correcting for gender differences, the influence of pathology on PTF was determined
to be significant (P < .001). Post hoc tests found a significant difference between normal
and polyp subjects (P < .001) but not normal and nodule subjects (P = .177) or nodule
and polyp subjects (P = .246). ROC analysis found that PTF (area under the curve [AUC]
= 0.691) andMFR (AUC = 0.684) had a similar diagnostic utility. PTF can be used to dif ferentiate between normal and pathological voices. As a parameter that is experimentally
sensitive to the biomechanical parameters providing its theoretical basis, it could be used
clinically to analyze laryngeal functionality," wrote P. Zhuang and colleagues, Fudan Uni versity. The researchers concluded: "Future research could focus on measuring PTF in
other pathologies, such as paralysis or scarring, which would also affect the effort required to produce voice." Zhuang and colleagues published their study in

Studies from Wexham Park Hospital provide new data on dysphonia
Biotech Business Week, April 6, 2009, p.601

TEXT:
9 APR 6 - (NewsRx.com & NewsRx.net) -- "The hoarse voice is a common presentation in the adult ENT clinic (see also Dysphonia). It is estimated that
otolaryngology/voice clinics receive over 50 000 patients with dysphonia each year," scientists in Slough, the United Kingdom report. "Good vocal function is estimated to be required for around 1/3 of the labour force to fulfil their job requirements. The assessment
and management of the patient with a hoarse voice is potentially a complex and protrac ted process as the aetiology is often multi-factorial. This article provides a guide for the
clinician in the general ENT clinic to make a concise, thorough assessment of the hoarse
patient and engage in an evidence based approach to investigation and management.
Literature search performed on 4 October 2008 using EMBASE, MEDLINE, Cochrane
databases using subject headings hoarse voice or dysphonia in combination with dia gnosis, management, investigation, treatment, intervention and surgery. General vocal
hygiene is beneficial for non organic dysphonia but the evidence base for individual components is poor. There is a good evidence base for the use of voice therapy as first line
treatment of organic dysphonia such as vocal fold nodules and polyps. There
is little evidence for surgical intervention as first line therapy for most common benign vocal fold lesions. Surgery is, however, the treatment of choice for hoarseness due
to papillomatosis. Both CO2 laser and microdissection are equally acceptable modalities
for surgical resection of common benign vocal fold lesions. Laryngopharyngeal reflux is
commonly cited as a cause of hoarseness but the evidence base for treatment with
gastric acid suppression is poor. Despite the widespread use of proton pump inhibitors
for treating laryngopharyngeal reflux, there is high quality evidence to suggest that they
are no more effective than placebo. A concise and thorough approach to assessment in
the general ENT clinic will provide the diagnosis and facilitate the management of the
hoarse voice in the majority of cases. Voice therapy is an important tool that should be
utilised in the general ENT clinic and should not be restricted to the specialist voice clinic. If there is no improvement after initial measures, the larynx appears normal and/or
the patient has failed initial speech & language therapy, referral to a specialist voice clin ic may be helpful," wrote I. Syed and colleagues, Wexham Park Hospital. The researchers
concluded: "More research is still required particularly with regard to laryngopharyngeal
reflux which is often cited as an important cause of hoarseness but is still poorly under stood." Syed and colleagues published their study in

9 MAR 24 - (NewsRx.com & NewsRx.net) -- According to a study from Netherlands, "
Vasomotor symptoms and bone loss are complications frequently induced by adjuvant
treatment for breast cancer (see also Breast Cancer). Tibolone prevents both side-effects, but its effect on cancer recurrence is unknown." "The aim of this study was to
show non-inferiority of tibolone to placebo regarding risk of recurrence in breast-cancer
patients with climacteric complaints. Between July 11, 2002, and Dec 20, 2004, women
surgically treated for a histologically confirmed breast cancer (T1-3N0-2M0) with vasomotor symptoms were randomly assigned to either tibolone 2.5 mg daily or placebo at
245 centres in 31 countries. Randomisation was done by use of a centralised interactive
voice response system, stratified by Centre, with a block size of four. The primary endpoint was breast-cancer recurrence, including contralateral breast cancer, and was analysed in the intention-to-treat (ITT) and per-protocol populations; the margin for non-in feriority was set as a hazard ratio of 1.278. This study is registered with ClinicalTrials.gov, number NCT00408863. Findings of the 3148 women randomised, 3098 were in-
cluded in the ITT analysis (1556 in the tibolone group and 1542 in the placebo group).
Mean age at randomisation was 52.7 years (SD 7.3) and mean time since surgery was
2.1 years (SD 1.3). 1792 of 3098 (58%) women were node positive and 2185 of 3098
(71%) were oestrogen-receptor positive. At study entry 2068 of 3098 (67%) women used tamoxifien and 202 of 3098 (6.5%) women used aromatase inhibitors. The
mean daily number of hot flushes was 6.4 (SD 5.1). After a median follow-up of 3.1
years (range 0.01-4.99), 237 of 1556 (15.2%) women on tibolone had a cancer recurrence, compared with 165 of 1542 (10.7%) on placebo (HR 1.40 [95% CI 1.14-1.70];
p=0.001). Results in the per-protocol population were similar (209 of 1254 [16.7%] women in the tibolone group had a recurrence vs 138 of 1213 [11.4%] women in the
placebo group; HR 1.44 [95% CI 1.16-1-79]; p=0.0009). Tibolone was not different
from placebo with regard to other safety outcomes, such as mortality (72 patients vs 63
patients, respectively), cardiovascular events (14 vs 10, respectively), or gynaecological
cancers (10 vs 10, respectively). Vasomotor symptoms and bone-mineral density improved significantly with tibolone, compared with placebo," wrote P. Kenemans and col leagues, Vrije University Amsterdam. The researchers concluded: " Tibolone increases
the risk of recurrence in breast cancer patients, while relieving vasomotor symptoms and
preventing bone loss." Kenemans and colleagues published the results of their research

9 FEB 26 - (NewsRx.com & NewsRx.net) -- "The aim of this study was to evaluate
the short-term and long-term results of the subadventitial resection of carotid chemod ectomas and to validate the importance of deliberate resection of the external carotid
artery (ECA) (see also Angiology). From 1981 to 2006, 39 carotid chemodectomas of the
carotid bifurcation or of the neighboring nerves were operated on in our department," researchers in Paris, France report. "There were 14 men and 22 women, with a mean age
44.4 +/- 5 (range 21-78) years. One of these operations was a redo surgery for local recurrence. One female patient presented with a bilateral tumor. Two tumors were secreting catecholamines. All these tumors affected the carotid body; 10 of them were also affecting the vagus nerve, and one among these last 10 affected the sympathetic nerve as
well. In 11 cases, the tumor had spread into the subparotidal space and, in one case,
into the skull. In two cases, the tumor had been revealed by hemispheric ischemia and in
every case by tumoral syndrome. All the patients were followed up by clinical examina tion, duplex scan, or computed tomographic scan until the end of 2006. In 38 cases,
complete resection was performed; an incomplete resection was performed in one case
with cranial invasion. Under general anesthesia, and most of the time without pharma ceutical preparation, surgery consisted of a deliberate sacrifice of the ECA followed by
subadventitial resection of the tumor. In one case, a previous embolization had been carried out to facilitate the cleavage, which in fact rendered it more complicated. In 22
cases, resection concerned the ECA; in seven cases, it concerned the common carotid
artery and the internal carotid artery (ICA): in seven cases the superior laryngeal nerve,
in nine cases the vagus nerve, in five cases the sympathetic nerve, and in four cases the
jugular vein. In 13 cases, node clearing was associated. In 20 cases, an additional vas cular procedure was performed: nine dilatations for spasm of the ICA,. five autogenous
vein grafts, two prosthetic bypasses, and one endarterectomy associated with a patch
angioplasty. All patients were followed up until 2006. At 3 months, the observed complic ations were the sequelae of a homolateral hemispheric accident due to thrombosis of a
vein graft, eight peripheral facial nerve palsies, 12 vocal palsies, seven Claude Bernard-Horner (CBH) syndromes, eight palatal paralyses, and 10 nociceptive pains. Some of
these complications did persist: nine vocal cord paralyses that were successfully
treated by speech therapy, three mild CBH syndromes, and nociceptive pains in 6% of
the cases (15.4%), incapacitating in one case. With a follow-up of 115 +/- 27 (range 1298) months, three local recurrences were recorded at 6 and 10 years. In two cases, local recurrence occurred when initial resection of the ECA had not been performed. Two
patients presented with a contralateral lesion, at 12 and 16 years, respectively. At 40
months, one patient had to be reoperated on for an atheromatous stenosis," wrote F.
Koskas and colleagues. The researchers concluded: "At 51 months, a female patient's
death was not related to the operation. Subadventitia'." Koskas and colleagues published

9 FEB 2 - (NewsRx.com & NewsRx.net) -- "The aim of this clinical study was to evaluate the effect of laryngopharyngeal reflux (LPR) on the healing process of surgical
laryngeal trauma (see also Acid Reflux Disease). A total of 112 consecutive patients, who
suffered from LPR and were scheduled for operation of Reinke edema or laryngeal
polyps/nodules (40 and 72 patients, respectively) during a period of 5 years, were included," scientists in Athens, Greece report. "Diagnosis of LPR was made on the basis of
both history and dual pH probe recording during 24 h in the inferior esophagus and the
hypopharynx. The reflux finding score (RFS) and the reflux symptom index (RSI) were
used to estimate the clinical severity of LPR. In patients with LPR, proton pump inhibitors
(PPI) were initiated in half of them, randomly chosen. Fifty LPR-free subjects operated
for Reinke edema or laryngeal polyps during the same time period (19 and 31 patients,
respectively) were used as controls. In six patients who had been administered PPI, resolution of the disease was observed and no surgical treatment was undertaken. The remaining patients were operated on under general anesthesia by a single surgeon. All patients had 1-year postoperative follow-up. Epithelization was complete in all vocal cords
of both the control group and the group of patients who had been administered PPI.
Within the group of patients who had not taken PPI, six patients presented granulation
tissue or recurrence of the polyps and in two of them revision surgery was needed. RFS
and RSI scores showed significant improvement postoperatively, across all the three
groups of patients, with major differences observed in the group treated by PPI. Comparison of the postoperative RFS and RSI scores between the two groups of patients with
LPR showed statistically significant differences in both, indicating better treatment out come in those patients who had received PPI. It may be thus concluded that LPR influ ences epithelization and recurrence of laryngeal polyps or Reinke edema in vocal cords,
after partial or total decortication," wrote I. Kantas and colleagues. The researchers concluded: "Surgical outcome is superior in patients with LPR with preoperative and postoperative anti-reflux treatment." Kantas and colleagues published their study in

8 AUG 14 - ( & NewsRx.net) -- Current study results from the report, 'Risk factors
for well-differentiated thyroid carcinoma in patients with thyroid nodular disease,' have
been published (see also ). According to recent research from Canada, "Evaluate current
accepted risk factors for well-differentiated thyroid carcinoma, and develop a predictive
model to determine one's risk of malignancy given a thyroid nodule. Retrospective analysis of 600 patients." "Patients with benign thyroid nodular disease and with well-differ entiated thyroid cancer were randomly selected. clinical, and investigational data were
compared by means of univariate and multivariate regression analyses. Age, regional
lymphadenopathy, ipsilateral vocal cord palsy, solid and/or calcified nodules, and an aspiration biopsy being malignant or suspicious predicted for cancer (p <0.05). Regional
lymphadenopathy and vocal cord palsy are perfect predictors of malignancy. Multivariate
analysis indicated age, solid and/or calcified nodules, and all fine-needle aspiration
biopsy results to be significant in assessing risk (p <0.05). Taking individual risk factors
in isolation is not always reliable," wrote S.N. Raza and colleagues, University of Toronto.
The researchers concluded: "Using a predictive model, one can anticipate a patient's risk
of malignancy when the diagnosis is unclear." Raza and colleagues published their study

8 AUG 4 - ( & NewsRx.net) -- " Endoscopic thyroidectomy (ET) is a demanding sur gical technique in which dissection of the gland is entirely performed with an endoscope,
in a closed area maintained by insufflation or mechanical retraction (see also ). ET by
direct cervical approach (anterior or lateral) is minimally invasive, but ET using an ex tracervical access (chest wall, breast, or axillary) is not," researchers in Marseille, France
report. "No technique seems to be universally accepted yet. This review was designed to
clarify the existing evidence for performing endoscopic thyroid resections in the management of benign thyroid nodules. A database search was conducted in PubMed and Embase from which summaries and abstracts were screened for relevant data, matching our
definition. Publications were further assessed and assigned their respective levels of
evidence. Additional data derived from our own unit's experience with endoscopic
thyroidectomy were included. Thirty mainly retrospective cohort studies have been published in which morbidity, such as unilateral vocal cord palsy, is poorly evaluated. ET
takes from 90 to 280 minutes for lobectomy by cervical access and total thyroidectomy
by chest wall approach, respectively. Cosmetic outcome in extracervical approach is less
troubled by size of the resected specimen compared with direct cervical approach. Extracervical approach avoids a neck scar but implies invasiveness in terms of dissection
and postoperative discomfort. Long-term cosmetic outcome comparisons with conventional thyroidectomy have not been published. Currently it is not possible to recommend
the application of ET based on evidence. Reported complications stress the importance of
advanced endoscopic skills. ET should only be offered to carefully selected patients and,
therefore, a high volume of patients requiring thyroid surgery is needed. Superiority of
endoscopic to conventional thyroidectomy has yet to be demonstrated," wrote E.T.
Slotema and colleagues. The researchers concluded: "Possible advantages of endoscopic
thyroid techniques and our patient's desire for the highest cosmetic outcome possible
justify further development of ET in expert hands of endocrine surgeons." Slotema and

8 JUN 17 - ( & NewsRx.net) -- "Cases of leiomyosarcoma in the head and neck are
very rare with only four reports of a leiomyosarcoma originating in the hypopharynx (see
also ). A rare case of leiomyosarcoma of the hypopharynx is described," researchers in
Morohongo, Japan report. "A 62-year-old woman, who had experienced slight difficulty of
swallowing and hoarseness, visited our hospital. A smooth-surfaced tumor was found ex tending from the postcricoid to an area in the left pyriform sinus, and the vocal cord on
the left side was fixed. Imaging studies, including FDG-PET CT imaging showed the tu mor in the postcricoid, but no distinguishable distant metastases. A total laryngectomy
with a left-lobe thyroidectomy was per-formed. Since no metastases of the regional
lymph nodeswere found by imaging, a neck dissection was not performed. Dense infiltration by spindle-shaped and/or round-like cells was observed histologically as the pre dominant growth pattern. In immunohistochemical staining, the tumor was positive for
desmin and muscle actin, while it was negative for myoglobin, myogenin, cytokeratin,
and S-100 protein. Electron microscopic examination did not show Z banding and sar comeres. Those features lead to the diagnosis of a leiomyosarcoma. No recurrence has
been found at 1 year after the surgery," wrote T. Takahashi and colleagues. The researchers concluded: "Immunohistochemical staining and electron microscopic examina tion are essential for a definite diagnosis of leiomyosarcoma." Takahashi and colleagues

8 JUN 3 - ( & NewsRx.net) -- According to recent research from Rome, Italy,
" Voice and swallowing symptoms are frequently reported after thyroidectomy even in
absence of objective voice alterations (see also ). We evaluated the influence of the
video-assisted approach on voice and swallowing outcome of thyroidectomy." " Sixty-five patients undergoing total thyroidectomy (TT) were recruited. Eligibility criteria
were: nodule size <= 30 mm, thyroid volume <= 30 ml, no previous neck surgery. Exclusion criteria were: younger than aged 18 years and older than aged 75 years, vocal fold paralysis, history ofvoice, laryngeal or pulmonary diseases, malignancy other
than papillary thyroid carcinoma. Patients were randomized for video-assisted (VAT) or
conventional (CT) thyroidectomy. Videostrobolaryngoscopy (VSL), acoustic voice analysis (AVA), and maximum phonation time (MPT) evaluation were performed preoperatively
and 3 months after TT. Subjective evaluation of voice (voice impairment score = VIS)
and swallowing (swallowing impairment score = SIS) were obtained preoperatively, 1
week, 1 month, and 3 months after TT. Fifty-three patients completed the postoperative
evaluation: 29 in the VAT group, and 24 in the CT group. No laryngeal nerves injury was
shown at postoperative VSL. Mean postoperative MPT, F (0), F (low), F (high), and the
number of semitones were significantly reduced in the CT group but not in the VAT
group. Mean VIS 3 months after surgery was significantly higher than preoperatively in
CT group but not in the VAT group. Mean SIS was significantly decreased 1 and 3 months
after VAT but not after CT," wrote C.P. Lombardi and colleagues, Catholic University. The
researchers concluded: " The incidence and the severity of early voice and swallowing
postthyroidectomy symptoms are significantly reduced in patients who undergo VAT
compared with conventional surgery." Lombardi and colleagues published their study in

8 MAY 27 - ( & NewsRx.net) -- Investigators publish new data in the report 'Pediatric Voice-Related Quality of Life: findings in healthy children and in common laryngeal
disorders.' "Although several instruments have been validated to assess voice quality,
the incidence and degree of impairment in normal, healthy children has not been widely
reported (see also ). It is hypothesized that healthy children outside a medical setting do
not demonstrate impairment as measured by the Pediatric Voice-Related Quality of Life
(PVRQOL) instrument; in contrast, patients with vocal fold paralysis (VFP), vocal nodules (VNs), and paradoxicalvocal fold dysfunction (PVFD) have significant impairment as
compared to control populations," researchers in the United States report. "The PVRQOL
was measured prospectively in children with VFP, VNs, and PVFD. The findings were com pared to findings in 100 children surveyed at the 2006 Wisconsin State Fair. Of the 100
surveys of healthy children and their parents, 95 were completed correctly; their mean
(+/-SD) PVRQOL score was 96.8 +/-5.85. The VFP patients (n=11; mean PVRQOL score,
70.5 +/-28.6) reported significant impairment (p <.0001, unpaired t-test). This was also
true of patients with VNs (n=13; PVRQOL score, 84.8 +/-9.4; p<.0001) and PVFD
(n=25; PVRQOL score, 86.7 +/-14.3; p<.0001); statistically significant differences were
also noted for the Social-Emotional and Physical-Functional domains for each of the 3
disease states compared to the group of healthy children (p <.001). The PVRQOL scores
of healthy children reveal essentially no self-reported vocal impairment. In contrast,
common disorders such as VNs, VFP, and PVFD demonstrate statistically significant
impairment in age-matched children for total PVRQOL, as well as for the Social-Emotion al and Physical-Functional domains," wrote A.L. Merati and colleagues, Medical College of

8 MAY 20 - ( & NewsRx.net) -- A new study, 'Vocal nodules and edema may be due
to vibration-induced rises in capillary pressure,' is now available (see also ). " Vocal fold
vibration may physically raise intravascular pressure to levels high enough to damage
capillaries and result in leakage of erythrocytes. This type of injury is commonly seen in
benign vocal fold lesions and is not well explained. Theoretical, retrospective," scientists
in the United States report. "The relationship of intravascular pressure to vibration fre quency and amplitude is derived and confirmed with a physical blood vessel model, then
applied to published human measurements to estimate human intravascular pres sures. Vocal fold intravascular pressure is predicted to have a quadratic dependence on
both frequency and amplitude. During speaking, the pressure may rise to over 20 cmH
O, and may reach levels far higher for screaming and singing. Such pressure magnitudes
are known to trigger inflammatory cascades and can lead to fluid leakage. They also
have the potential for pharmacologic control with beta-agonists. Intravascular pressure
likely rises significantly during vocal fold vibration and may lead to the type of injury
seen in benign vocal fold lesions. The results support voice therapy aimed at reducing
vibratory amplitude," wrote L. Czerwonka and colleagues, University of Wisconsin. The
researchers concluded: "More vibratory amplitude measurements need to be performed
in a wider range of subjects before the full range of human vocal fold vascular pressures

"The study is designed as a prospective, nonrandomized survey. The objective of this
study is to determine the voice problems of first year graduate students training to be
SLPs. Participants were 104 first year graduate students majoring in speech-language
pathology at two universities. The Quick Screen for Voice was administered. Participants
who failed completed a questionnaire regarding voice problems, medical history, daily
habits, and voice use. When responses further indicated voice-related problems, endoscopic examination was completed. Fourteen percent (N = 15) of the participants failed
the screening by demonstrating two or more abnormal voice characteristics. These included persistent glottal fry (present in all who failed), low habitual pitch, juvenile reson ance, hoarse, breathy, or strained phonation, abnormally low pitch on sustained vowels,
and voice breaks during the frequency range. Twelve percent (N = 12) failed both the
screening and follow-up questionnaire. Responses included self-reported dysphonia,
medical history with voice-related side effects, difficulty with excessive voice use,
and voice problems occurring daily or weekly. Endoscopic evaluation showed one participant with bilateral vocal nodules. The results suggest that voice problems among future SLPs (12%) are more common than the 3-9% reported in the general population

TEXT:
8 JAN 28 - ( & NewsRx.net) -- New research, 'Vagus nerve stimulation therapy for
seizures,' is the subject of a report (see also ). "Of the 3 million patients with seizures in
North America approximately 70% have effective seizure control with medications. In the
group refractory to medical treatment only a minority fit the criteria for surgical therapy,"
investigators in the United States report. "Vagus nerve stimulation therapy seems to be a
suitable nonpharmacologic therapy for reducing seizure frequency in these cases. It is a
simple device with 2 electrodes and an anchor loop implanted on the midcervical portion
of left vagus nerve and the impulse generator is implanted subcutaneously in the left in fraclavicular region. The left vagus is the preferred site as the right vagus innervates the
sinoatrialnode and influences the heart rate. Data from laboratory studies suggest that it
most probably works by increasing the release of norepinephrine in the locus ceruleus,
which in turn increases the seizure threshold. More than 32,000 devices have been implanted since it was approved in 1997. There is class I evidence that vagus nerve stimulator reduces the frequency of seizures. In addition it also elevates the patients' moodindependent of seizure control. In one of the studies 50% reduction in seizure frequency
was 37% in the first year and 44% in the second and third year. The side effects commonly reported are constriction in the throat, change in voice, and throat pain which
most patients are able to tolerate and continue the use of the device," wrote R. Ramani

unilateral (66.7%) and right-side larynx but multiple subsites of the larynx (57.7%). The
appearance of the affected larynx may have mixed features and change before diagnosis. Laryngeal tuberculosis is usually misdiagnosed as laryngeal cancer, especially in pa tients with malignant signs such as enlarged cervical lymph nodes and vocalfold immobility.

7 OCT 23 - ( & NewsRx.net) -- A new study, 'Vocal fold masses,' is now available
(see also ). "'Vocal fold masses are often complex in nature and can have a devastating
result on the professional voice. These lesions are usually multifactorial with synergistic contributions over time from voice use demands and technique, medical conditions,
medications, and the environment," investigators in the United States report. "General
categories of benign vocal fold masses inprofessional voice include nodules, polyps,
and cysts, but other pathology should be considered, such as reactive lesions, intracordal
scarring, feeding varices, and reparative granuloma. A perspective on these issues is essential for proper diagnosis and management," wrote K.W Altman and colleagues, Mount

7 OCT 9 - ( & NewsRx.net) -- "In Canada, endoscopic resection using a CO2 laser
has been generally ignored as a treatment option (see also ). In this article, we present
an introductory analysis of our clinical experience with the CO2 laser at the QEII Health
Sciences Centre in Halifax, Nova Scotia," investigators in Halifax, Canada report. "Out comes from a cohort of 36 patients with glottic cancer staged as Cis-T2 (7 Cis, 17 T1,
12T2) who underwent endoscopic resection using a CO2 laser between January 2002 and
June 2005 were studied retrospectively. The mean follow-up was 16.2 months (range 041 months). At the time of the study, no patient had died of laryngeal disease, one pa tient had died of another disease, and one patient was lost to follow-up. There had been
three recurrences in the cohort: two local recurrences and one recurrence in a regional
lymph node. After salvage, all patients with recurrences were disease free at the time of
the study. There were three postoperative complications in the cohort: one postoperative
myocardial infarction, one case of respiratory distress postextubation, and one case of
subcutaneous emphysema. The average time for the procedure was 0.97 hours (range
0.25-2.75 hours). The average postoperative length of stay was 1.2 days (range 0-12
days). Of 35 cases with follow-up, 60% had no reported problems with voice in their last
visit and 11% reported consistent hoarseness or weakness," wrote M.H. Rigby and colleagues. The researchers concluded: "Although our oncologic results do require more follow-up, based on our positive experience thus far, we believe that endoscopic management of glottic cancer is a treatment option that may be underused in the Canadian
health care system." Rigby and colleagues published their study in the

Researchers detail in "Hoarseness in children: the role of laryngopharyngeal reflux,"
new data in acid reflux disease. According to a study from the United States, "The role of
laryngopharyngeal reflux (LPR) in hoarseness in children is not well studied. The purpose
of this study was to determine the prevalence of LPR in hoarse children." "Retrospective
chart review identified 337 children with hoarseness over a 3-year period. Data collected: mode of presentation, associated symptoms, endoscopic findings, laboratory test ing, and therapeutic interventions and their outcomes. Mean age at presentation was
7.2+/-4.3 years with a male:female ratio of 1.7:1. Of the 295/337 (88%) children who
underwent endoscopy, 107/295 (36%) had LPR changes alone, 86/295 (29%) had vocalfold nodules, 63/295 (20%) had both LPR and vocal fold nodules; and 22/295
(7%) had a finding other than LPR or nodules. Of the children diagnosed with LPR by
endoscopy (with or without nodules), 93/170 (55%) underwent at least one additional
test for reflux with 69/93 (74%) having a positive test. Of the children diagnosed with
LPR by endoscopy, neither cough nor throat clearing was identified in 82/170 (48%) of
children. At the first follow-up visit, an average of 3 months from initial presentation,
50% of 169 children who were treated for reflux had improved or resolved. By the
second follow-up visit, 4.5 months later, 68% of those children had improved or resolved. LPR appears to be a very common cause of hoarseness in children, and is an increasingly important symptom in identifying children with LPR," wrote B.B. Block and col leagues, State University of New York. The researchers concluded: "Treatment of LPR often results in improvement of hoarseness." Block and colleagues published their study in

Recent research from University of Sao Paulo, Brazil, summarized. This trend article
about University of Sao Paulo, Brazil, is an immediate alert from NewsRx to identify de veloping directions of research. Study 1: Scientists discuss in " Vocal evaluation in teachers with or without symptoms" new findings in life sciences. "The aim of this study was
to perform voice evaluation in teachers with and without vocal symptoms, identifying
etiologic factors of dysphonia, voice symptoms,vocal qualities, and laryngeal lesions.
Eighty teachers were divided into two groups: GI (without or sporadic symptoms, 40)
and GII (with frequent vocalsymptoms, 40)," researchers in Sao Paulo, Brazil report.
"They answered a specific questionnaire, and were subject to a perceptual vocal assessment (maximum phonation time, glottal attack, resonance, coordination of breathing and
voicing, pitch, and loudness), GIRBAS scale, and to videolaryngoscopy. Females were
predominant in both groups, and the age range was from 36 to 50 years. Elementary
teachers predominated, working in classes with 31-40 students. Voicesymptoms and alterations in the perceptual vocal analysis and in the GIRBAS scale were more frequent in
GII. In 46 teachers (GI-16; GII-30), videolaryngoscopy exams were abnormal with
the vocal nodules being the most frequent lesions," wrote E.L. Tavares and colleagues,
University of Sao Paulo, Department of Otolaryngology. The researchers concluded:
"These results indicate that a teacher's voice is compromised, and requires more attention including control of environmental factors and associated diseases, preventive vocal hygiene, periodic laryngeal examinations, and access to adequate specialist treat ment." Tavares and colleagues published their study in the Journal of Voice (Vocal evaluation in teachers with or without symptoms.
. Journal of Voice , 2007;21(4):407-14). For additional information, contact E.L. Tavares, Sao Paulo State University (UNESP), Dept. of Otolaryngology, Botucatu City, Sao
Paulo, Brazil. Study 2: Ketoprofen (KP) transdermal delivery is investigated as well as
the influence of dioleylphosphatidylcholine (DOPC) on skin permeation. "Considering that
most inflammatory diseases occur locally and near the body surface, transdermal deliv ery of nonsteroidal anti-inflammatory drugs (NSAIDs) may be an interesting strategy for
delivering these drugs directly to the diseased site. To optimize ketoprofen (KP) trans dermal delivery we investigated the influence of dioleylphosphatidylcholine (DOPC) on
skin permeation," report researchers writing in the journal Pharmaceutical Research .
M.T.J. Garcia and colleagues, University of Sao Paulo, explained, "The formulations stud ied were: i) a physical mixture of KP and DOPC and ii) DOPC and KP complex, in a molar
ratio of 1:3, obtained by dissolution of the components in chloroform followed by drying
under a N-2 atmosphere. Both systems were dispersed in mineral oil and the in vitro
percutaneous was assayed by absorption using a flow through diffusion cell. Differential
Scanning Calorimetry (DSC) and H-1 NMR studies were carried out to characterize KP
and DOPC interactions. "Geometry optimizations using Density Functional Theory and
semiempirical methods, as well as a flexible docking procedure were carried out to obtain a binding model for KP with DOPC. KP solubility and partition studies in the formula tions, as well as skin irritation and hypersensitivity assays were also carried out. DSC de terminations in the complex showed enthalpy and temperature depressions, indicating
KP and DOPC interaction." They continued, "In addition, dipole-dipole interactions
between the KP carboxylic acid and OH groups in phospholipids were shown by H-1 NMR
studies. Based on the NMR studies, a KP-DOPC binding model is proposed, in which KP is
involved by the two long aliphatic chains of the phospholipid. Solubility studies indicated
that DOPC improved drug solubility. KP permeation was enhanced by both formulations
tested, but the complex also increased its skin uptake. Such behavior could be attributed
to the solubilizing, melting and enhancing effects of DOPC." The researchers concluded,
"Skin irritation and hypersensitivity were not significantly changed compared to control,
suggesting that the formulation may be therapeutically explored for KP transdermal de livery." Garcia and colleagues published their study in Pharmaceutical Research (Trans dermal delivery of ketoprofen: The influence of drug-dioleylphosphatidylcholine interac tions.

Brazil, "The objective was to examine the relationship between pre-, peri-, and postoperative specialized nutritional support with immune-modulating nutrients and postoperative
morbidity in patients undergoing elective surgery. "Studies were identified by searching
MEDLINE, review article bibliographies, and abstracts and proceedings of scientific meet ings. All randomized clinical trials in which patients were supplemented by the IMPACT
formula before and/or after elective surgery and the clinical outcomes reported were included in the meta-analysis." "Seventeen studies (n=2,305), 14 published (n=2,102),
and 3 unpublished (n=203), fulfilled the inclusion criteria. Ten studies (n=1,392) ex amined the efficacy of pre- or perioperative IMPACT supplementation in patients under going elective surgery, whereas 7 (n=913) assessed postoperative efficacy. "Fourteen of
the studies (n=2,083) involved gastrointestinal (GI) surgical patients. Postoperative
complications, mortality, and length of stay in hospital (LOS) were major outcomes of in terest," D.L. Waitzberg and colleagues at the University of Sao Paulo wrote. "IMPACT
supplementation, in general," reported investigators, "was associated with significant
(39-61%) reductions in postoperative infectious complications and a significant decrease
in LOS in hospital by an average of 2 days. "The greatest improvement in postoperative
outcomes was observed in patients receiving specialized nutrition support as part of their
preoperative treatment. In GI surgical patients, anastomotic leaks were 46% less prevalent when IMPACT supplementation was part of the preoperative treatment." Waitzberg
concluded, "This study identifies a dosage (0.5-1 l/day) and duration (supplementation
for 57 days before surgery) of IMPACT that contributes to improved outcomes of morbidity in elective surgery patients, particularly those undergoing GI surgical procedures.
"The cost effectiveness of such practice is supported by recent health economic analysis.
Findings suggest preoperative IMPACT use for the prophylaxis of postoperative complica tions in elective surgical patients." Waitzberg and colleagues published their study in

Fresh data on squamous cell carcinoma are presented in the report "Surgical management of carcinoma of the cervical esophagus. The aim of the present study was to
clarify the clinicopathological characteristics, reconstruction methods after resection, and
prognosis of cervical esophageal squamous cell carcinoma. Seventy-four with squamous
cell carcinomas of the cervical esophagus not previously treated who underwent cervical
esophagectomy or total esophagectomy with or without laryngectomy were retrospectively analyzed," scientists in Kashiwa, Japan report. "The operative morbidity and in-hos pital mortality rates were 34% (25 patients) and 4% (3 patients), respectively. Alimentary continuity was achieved with free jejunal transfer (50 patients), gastric pull-up (19
patients), and other procedures (5 patients). The frequencies of postoperative complications and death did not differ between free jejunal transfer and gastric pull-up. The over all 3-and 5-year survival rates were 42% and 33%, respectively. The significant clinicopathological factors affecting survival were patient gender, high T factor,
lymph node involvement, palpable cervical lymph nodes, vocal cord paralysis, lymphatic invasion, and extracapsular invasion. The pattern of first failure was most often locore gional (82%, 36 patients). The choice of free jejunal transfer or gastric pull-up for reconstruction after surgical resection of cervical esophageal carcinoma depends on the degree of tumor extension," wrote H.

Findings from Johns Hopkins University, U.S., research reported. This trend article
about Johns Hopkins University, U.S., is an immediate alert from NewsRx to identify de veloping directions of research. Study 1: A new study, "Noradrenergic projections to the
song control nucleus area X of the medial striatum in male zebra finches (Taeniopygia
guttata)," is now available. According to recent research from the United States, "There
is considerable functional evidence implicating norepinephrine in modulating activity in
the vocal control circuit of songbirds. However, our knowledge of noradrenergic inputs to
the song system is incomplete." "In this study, cholera toxin subunit B (CTB) injections
into area X revealed projections from the noradrenergic nuclei locus coeruleus and subcoeruleus, and injections of biotinylated dextran amines into these noradrenergic nuclei
labeled fibers in area X. The nonreciprocity of this connection was demonstrated by the
absence of retrogradely labeled cells in area X following injections of CTB into the locus
coeruleus. Additionally, we found novel inputs to area X from the nidopallium and ar copallium, the mesencephalic central gray, and the dorsolateralis anterior (DLL) and pos terior (DLP) lateralis in the thalamus. Area X can be clearly distinguished from the sur rounding medial striatum based on cytoarchitectural and chemical neuroanatomical cri teria. We show here that neuromodulatory inputs to area X however, exhibit a considerable degree of overlap with the surrounding area. This finding suggests that regional
specificity in neuromodulator action is most likely afforded by a specialization in receptor
density and enzyme distribution rather than projections from the synthesizing nuclei. Our
results extend current knowledge about noradrenergic projections to specialized nuclei of
the song control circuit and provide neuroanatomical evidence for the functional action of
norepinephrine-modulating context-dependent ZENK expression in area X," wrote C.B.
Castelino and colleagues, Johns Hopkins University. The researchers concluded: "Furthermore, the novel projections to area X from telencephalic and thalamic areas could be
new and interesting nodes in the striatopallidothalamic loop spanning the songbird
brain." Castelino and colleagues published their study in the Journal of Comparative
Neurology (Noradrenergic projections to the song control nucleus area X of the medial
striatum in male zebra finches (Taeniopygia guttata).

improve cardiac size and left ventricular diastolic function. According to a study from the
United States, "To determine exercise training effects on cardiac size and left ventricular
(LV) diastolic function and relationships of exercise induced changes in physiological and
body composition parameters with cardiac parameters." K.J. Stewart and colleagues at
the Johns Hopkins School of Medicine conducted a "prospective, randomised controlled
trial. Men and women (63.6 (5.7) years, body mass index 29.5 (4.4) kg/m 2 ) with untreated hypertension (systolic blood pressure (BP) 130-159 or diastolic BP 85-99 mm
Hg) [were included]. [Main outcome measures were] cardiac size and LV diastolic func -
tion, peak oxygen uptake (Vo ), muscle strength, general and abdominal fatness, and in sulin resistance. [Subjects underwent] 6 months of exercise training versus usual care."
The data revealed, "When analysed by group at 6 months, cardiac size and LV diastolic
function did not differ between exercisers (n=51) and controls (n=53), whereas exercisers had significantly higher peak Vo (28 v 24 mL/kg/min) and strength (383 v 329
kg), and lower fatness (34% v 37%), diastolic BP (73 v 75 mmHg) and insulin resistance
(quantitative insulin sensitivity check index 0.35 v 0.34) versus controls (all pless than
or equal to0.05). By regression analysis, among 6 month changes, increased peak Vo
and reduced abdominal fat were associated with increased cardiac size. Increased peak
Vo and reduced abdominal fat, BP and insulin resistance were associated with improved
LV diastolic function. r Values ranged from 0.20 to 0.32 (pless than or equal to0.05)."
The researchers concluded, "When examined by group assignment, exercise had no effect on cardiac size or LV diastolic function. When individual variations in 6 month
changes were examined, participants attaining the greatest increases in fitness and re ductions in abdominal fatness, insulin resistance and BP showed a modest trend towards
physiological hypertrophy characterised by increased cardiac size and improved LV dia stolic function. These results suggest that decreased abdominal fatness may have a role
in improving cardiovascular health." Stewart and colleagues published the results of their
research in Heart (Exercise effects on cardiac size and left ventricular diastolic function:
relationships to changes in fitness, fatness, blood pressure and insulin resistance. Heart,

Adult neural stem and progenitor cell niche is altered in the amyotrophic lateral sclerosis
brain. "Amyotrophic lateral sclerosis (ALS) is a fatal adult human disease caused by mo tor neuron degeneration. Stem cell therapy might be a treatment for ALS," researchers
in the United States report. According to Z.P. Liu and colleagues at Johns Hopkins Uni versity, "The adult mammalian forebrain has neural stem cells (NSCs) and neural pro genitor cells (NPCs) in the anterior subventricular zone (SVZa), rostral migratory stream
(RMS), olfactory bulb (OB) core, and dentate gyrus (DG). "These cells could be used to
rescue or replace degenerating upper and lower motor neurons through endogenous recruitment or autologous/allogenic transplantation." "We evaluated the competency of
forebrain NSCs and NPCs in transgenic (tg) mice harboring human mutant superoxide
dismutase-1 (mSOD1), a model of ALS. Tg human wild-type SOD1 (wtSOD1) mice and
non-tg mice were controls. "Bromodeoxyuridine (BrdU) labeling of cells, a marker for cell
proliferation and other events, was reduced in a niche-specific pattern in presymptomatic
and symptomatic mice, with the SVZa having greater reductions than the RMS, OB, and
DG," investigators said. Scientists continued, "Different NSC and NPC complements were
evaluated by localizing nestin, neural cell adhesion molecule, distalless-2 transcription
factor, vimentin, and glial fibrillary acidic protein. "In symptomatic mice, NSC markers
were reduced, whereas NPC markers were unchanged or elevated. Neurogenesis was
preserved in symptomatic mSOD1 mice. NSC/NPC competence assessment in vitro revealed that mSOD1 SVZa cells had the ability to proliferate and form neurospheres but
had an impaired response to mitogen stimulation." The authors concluded that adult
"mSOD1 ALS mice have abnormalities in forebrain NSCs, but the essential features of
NSC/NPCs remained in presymptomatic and symptomatic mice." Liu and colleagues pub lished their study in the Journal of Comparative Neurology (The adult neural stem and

Findings from University Politecnica of Madrid in voice disorders pathology reported

LANGUAGE: English
WORD COUNT: 403
TEXT:
New research, "Evaluation of voice pathology based on the estimation of vocal fold
biomechanical parameters," is the subject of a report. According to recent research published in the Journal of Voice , " Voice disorders are a source of increasing concern as
normal voice quality is a social demand for at least one third of the population in de veloped countries in cases where voice is an essential resource in professional exercise. In addition, the growing exposure to certain pathogenic factors such as smoking,
alcohol abuse, air pollution, and acoustic contamination, and other problems such as
gastro-esopharyngeal reflux or allergy as well as aging, aggravate voice disorders."
"Voice pathologies justify the assignment of larger resources to prevention policies,
early detection, and less aggressive treatments. Traditional pathology detection relies on
perceptive evaluation methods (GRABS), acoustic analysis, and visual inspection (indir ect laryngoscopy, and modern fibro-endo-stroboscopy). This article describes a method
for voice pathology detection based on the noninvasive estimation of vocal cord biomechanical parameters derived from voice using specific signal processing methods.
Preliminary results using records from patients showing four frequent causes of voicepathology (nodules, polyps, chronic laryngitis, and Reinke's edema) are given. The results show that the alteration (distortion, unbalance, or deviation) of cord biomechanical
parameters may serve as an indicator of pathology. Statistical methods based on hier archical clustering and principal component analysis reveal that combining biomechanical
estimates with classic perturbation parameters increases the accuracy of acoustic analys is, improving the detection of voice pathology," wrote P. Gsmez-Vilda and colleagues,
University Politecnica of Madrid. The researchers concluded: "This research could open
new possibilities for noninvasive screening of vocal fold pathologies and could be used in
the implantation of e-health voice care services." Gsmez-Vilda and colleagues published
their study in the

Studies from State University of New York, U.S., highlight most recent research. This

from genital warts to cytologic abnormalities to cervical, vaginal, and vulvar cancers and
their associated precursor lesions. In addition, HPV is implicated in anal, penile, and

HPV vaccine (HPV 6/11/16/18) and phase 2 trials with a bivalent preventive HPV vaccine
(HPV 16/18) have demonstrated that both products are highly efficacious in preventing
type-specific HPV infections and HPV-related disease and are well tolerated. Nearly all re cipients demonstrate a robust immunologic response that currently appears to be dur able for 4 or more years. Immunogenicity data among girls 9 to 15 years of age were
used to "bridge" efficacy data from quadrivalent HPV vaccine trials completed to date. In
June 2006, the US Food and Drug Administration approved the quadrivalent HPV vaccine
for use among females 9 to 26 years of age. The Centers for Disease Control and Prevention's Advisory Committee on Immunization Practices has recommended the 3-dose
series for girls 11 to 12 years of age, catch-up vaccination for girls and women 13 to 26
years of age, and permissive use as early as age 9. Computer models projecting the impact of these preventive HPV vaccines predict that they will be cost-effective and benefi cial to the population; the use of preventive HPV vaccines will complement continued
cytologic screening programs. Trials are under way to evaluate the duration of immune
response as well as efficacy among men and women 27 years of age and older," wrote
M.C Mahoney and colleagues, State University of New York, Roswell Park Cancer Institute. The researchers concluded: "Girls and women within the targeted age ranges
should be offered vaccination to achieve the disease prevention potential of these vaccines." Mahoney and colleagues published their study in the Journal of Family Practice
(Protecting our patients from HPV and HPV-related diseases: the role of vaccines. Journal
of Family Practice, 2006;Suppl():10-7). For additional information, contact M.C. Ma honey, State University of New York at Buffalo USA., Dept. of Health Behavior, Roswell
Park Cancer Institute. Study 2: As part of a new study, SUNY Upstate Medical University
physicians will use traffic surveillance cameras to view motor vehicle crashes and rescue
operations on Central New York highways in hopes of learning how to provide better care
to crash victims when they arrive in the emergency room. The study - believed to be the
first of its kind in the nation - is being funded by the noted U.S. economist Alfred Kahn,
who survived a car crash in 2003 and spent weeks recovering from his injuries at SUNY
Upstate's teaching hospital, University Hospital. For the study, SUNY Upstate researchers
will have access to nearly 20 closed-circuit video cameras installed in and around Syra -
cuse by the New York state Department of Transportation (DOT). These cameras are
monitored by the DOT's Syracuse office 24 hours a day to assess traffic conditions in the
area. The cameras, controlled by DOT personnel, can pan, tilt and zoom to particular
areas of the roadway. Eleven cameras cover a 12-mile stretch of Interstate 81; 8 additional cameras will be in place shortly to cover a 12-mile stretch of Interstate 690. A
special receiving antenna brings the real time images into a specially outfitted worksta tion located near University Hospital's trauma room. Here, medical personnel can view
the crash scene and rescue efforts on a computer monitor. The technology for the workstation was provided by CXtec. When a crash occurs, DOT personnel will alert SUNY Upstate researchers and refer them to a particular camera to view the crash. Once the image is available on the computer Researchers can begin recording the images and
provide the DOT staff with instructions on whether to zoom or pan the camera. "We think
the ability to view real time images of the accident scene to see the extent of damage
and the response from paramedics can provide us with a wealth of information that may
help us better treat the accident victims when they arrive at the emergency room," said
John McCabe, MD, professor and chair of the Department of Emergency Medicine at
SUNY Upstate. Currently, first responders to an accident scene communicate with physicians via radio about the extent of injuries of those being transported to the hospital.
They may also provide physicians with information about what the accident scene looks
like and relay information about the accident from eyewitness accounts, if available.
Study 3: Elective lymph node (LN) excision might reduce morbidity and improve local
control in older patients with papillary thyroid cancer. Researchers in the United States
conducted a study "to determine the incidence of nodal involvement and assess the role
of elective LNB exploration and/or dissection in staging of tumors and treatment of pa tients with papillary thyroid cancer. One hundred patients diagnosed with papillary
thyroid cancer by fine-needle aspiration or intraoperative frozen section who underwent
total thyroidectomy with central compartment cervical LN exploration. [The] incidence of
positive LNs in patients 45 years or older (group A) [was compared to] those younger
than 45 years (group B)." "Sixteen (39%) of 41 patients in group A had positive LN
status following LN exploration and/or dissection," explained M. Shindo and colleagues,
State University of New York. "Seventeen (29%) of 59 patients in group B were found to
have positive LNs. According to the American Joint Committee on Cancer staging system,
the tumors of 11 patients (28%) in group A would be restaged from stage I/II to stage
III after establishment of the positive pathologic nodal status. Lymph node metastasis
was present in the central compartment in 39% of patients in group A. "Presence of LN
metastasis in older patients has been reported to increase the risk of recurrence of papillary thyroid carcinoma. Furthermore, recurrence and reoperation in the central compartment is associated with a higher risk of vocal cord paralysis. In patients in group A diagnosed with papillary thyroid carcinoma, routine central compartment LN exploration
and/or dissection at the time of thyroidectomy is advocated, which allows more accurate
staging of tumors and appropriate treatment." The researchers concluded, "Elective excision of central compartment LNs in this older age group may improve locoregional con trol and possibly reduce morbidity in the long run." Shindo and colleagues published
their study in

Research from University of Bern, Switzerland, provides new insights into human
health. This trend article about University of Bern, Switzerland, is an immediate alert
from NewsRx to identify developing directions of research. Study 1: Research findings,
"Vocal cord dysfunction: dealing with aggressivity," are discussed in a new report. Ac cording to recent research from Bern, Switzerland, "QUESTIONS UNDER STUDY: Vocal cord dysfunction (VCD) is characterised by recurrent attacks of paradoxical adduction
of the vocal cords during inspiration, accompanied clinically by dyspnoea attacks with
inspiratory stridor lasting between minutes and hours. The aim of the study is to evalu ate the self-perception of patients suffering from VCD and how they deal with aggressivity." "The Giessen Test (GT) and the Picture Frustration Test (PFT) were used on 6 patients with VCD. Five variables show significant differences between the patients with
VCD and the values of the normative groups. VCD-patients show an idealized image of
themselves, ie relaxed, open, sociable, and capable of devotion. They do not reject accusations against them by others and rarely make self-criticism. In conflicts they behave
passively, thus blocking their expression of aggressivity. In many cases organic disposi tion and trigger stimuli are thought to be responsible for provoking dyspnoea attacks in
VCD. However, the self-perception of patients and their way of dealing with aggressivity
strongly suggests that psychosocial factors play a great role in the development of VCD,"
wrote E. Seifert and colleagues, University of Bern. The researchers concluded: "This requires not only symptom-orientated therapy but also psychological counselling." Seifert
and colleagues published their study in Swiss Medical Weekly (Vocal cord dysfunction:
dealing with aggressivity. Swiss Medical Weekly, 2007;137(7-8):127-9). For additional
information, contact E. Seifert, University of Bern, Division of Phoniatrics, ENT-Clinic,
Head and Neck Surgery, Bern, Switzerland. Study 2: Pelvic lymph node dissection
(PLND) is warranted in prostate cancer patients undergoing radical prostatectomy with a
serum level of PSA <10 ng/ml. "Controversy persists concerning the role of PLND in patients with preoperative PSA values <10 ng/ml undergoing treatment for prostate cancer
with a curative intent. The aim of this study was to determine the incidence of
lymph node metastasis in this subgroup of patients," scientists in Switzerland reported.
"Patients with clinically localized prostate cancer and a serum PSA <10 ng/ml, without
neoadjuvant hormonal or radiotherapy, with negative staging examinations who under went radical retropubic prostatectomy with bilateral extended PLND and with greater
than or equal to10 lymph nodes detected by the pathologist in the surgical specimen,
were included in the study," explained M.C. Schumacher and colleagues, University of
Bern. "A total of 231 patients with a median serum PSA of 6.7 ng/ml (range 0.4-9.98)
and a median age of 62 years (range 44-76) were evaluated. A median of 20 (range 1072) nodes were removed per patient. Positive nodes were found in 26 of 231 patients
(11%), the majority of which (81%) had a Gleason score greater than or equal to7 in the
surgical specimen. "Of the patients with a Gleason score greater than or equal to7 in the
prostatectomy specimen 25% had positive nodes, whereas only 3% with a Gleason
score less than or equal to6 were node positive. The incidence of positive nodes in patients with clinically localized prostate cancer, a serum PSA <10 ng/ml and a Gleason
score greater than or equal to7 in the prostatectomy specimen was 25% after extended
PLND," informed the team. The researchers concluded, "It seems that in this patient
group extended PLND, including removal of nodes along the internal iliac vessels, is
warranted." Schumacher and colleagues published their study in
n European Urology (Is pelvic lymph node dissection necessary in patients with a
serum PSA <10 ng/ml undergoing radical prostatectomy for prostate cancer? Eur Urol,
2006;50(2):272-279). For more information, contact U.E. Studer, University of Bern,
Dept. of Urology, CH-3010 Bern, Switzerland. Study 3: Apolipoprotein B is a long-term
predictor of mortality in type 1 diabetes mellitus. According to a study from Switzerland,
"To evaluate the association of apolipoprotein B (apo B) with mortality due to all causes,
to cardiac disease and to ischaemic heart disease (IHD) in subjects with type 1 diabetes
mellitus. 165 subjects with type 1 diabetes included in the Swiss Cohort of the WHO Mul tinational Study of Vascular Disease in Diabetes were followed for 14.7+/-0.45 years.
Causes of death were obtained from death certificates, hospital records and postmortem
reports." "Using a parametric proportional hazards model the association of apo B with
mortality rates was assessed by time-to-event analysis, including the absolute cumulat ive mortality risk over time for various apo B levels at baseline," wrote C. Stettler and
colleagues, University of Bern. They discovered, "Apo B was positively associated with
all-cause mortality [hazard ratio (HR) 2.65 per g/L increase of apo B, 95% CI: 1.116.36, p=0.029], cardiac mortality (HR 11.64, 1.03-131.11, p=0.047) and IHD mortality
(HR 9.36, 1.26-69.66, p=0.029). An apo B greater than or equal to0.96 g/L translated
into a duplication of overall mortality hazard (HR 1.93, 1.00-3.72, p=0.050), and a sevenfold increase of mortality because of cardiac disease or IHD (HR 7.44, 1.44-38.42,
p=0.017 and HR 7.38, 0.78-69.82, p=0.081). "A baseline apo B of 1.5 g/L predicted an
absolute cumulative risk to die over the next 10 years of 12.1% (5.2-31.7) for male and
of 10.4% (4.7-26.1) for female subjects whereas risks were 6.3% (1.8-21.4) and 5.4%
(0.8-15.8) for an apo B of 0.8 g/L." The researchers concluded, "Apo B is consistently
associated with an increased mortality in type 1 diabetes." Stettler and colleagues pub lished the results of their research in the Journal of Internal Medicine (Apolipoprotein B

New data from University of Utah, U.S., detailed. This trend article about University
of Utah, U.S., is an immediate alert from NewsRx to identify developing directions of re search. Study 1: Fresh data on behavior are presented in the report "Behavioral characteristics of children with vocal fold nodules." According to recent research published in
the Journal of Voice , "Vocal fold nodules (VNs) in children are benign, bilateral lesions
occurring on the mid-membranous vocalfolds. Repetitive phonotraumatic behavior leading to chronic vocal fold injury and repair is frequently cited as the primary etiology;
however, specific behavioral characteristics may predispose some children toward intense
and potentially phonotraumatic voice use, thereby contributing secondarily to VN formation." "The purpose of this case-control study was to determine whether children with
VNs possess unique behavioral characteristics that may predispose them to VN develop ment. Parents of 26 children with VNs (20 boys, 6 girls, mean age=7.2 years, SD=2.5
years), and 29 vocally normal, medical controls (22 boys, 7 girls, mean age=6.7 years,
SD=2.4), completed the Childhood Behavior Checklist (CBCL/4-18, Achenbach, 1991), a
standardized parent-rating scale with strong psychometric properties. No significant
between-group differences were detected on any of the behavior problem syndrome
scales. Group differences approached significance for the individual items "screams a lot"
and "teases a lot" (VN group >Controls). The VN group scored significantly higher than
the controls on the "Social Scale," a compilation of positive ratings of the child's social
activity, frequency of contacts with friends, behavior with others, and behavior by them selves," wrote N. Roy and colleagues, University of Utah. The researchers concluded:
"Observed outcomes were consistent with previous characterizations of children with VN
as "outgoing" or "extroverted" but were not consistent with other claims that this popu lation may be at risk for "aggressive, attentional," or "impulsive" behavior problems."
Roy and colleagues published their study in the
Journal of Voice (Behavioral characteristics of children with vocal fold nodules. Journ al of Voice, 2007;21(2):157-68). For additional information, contact N. Roy, The University of Utah, From the Dept. of Communication Sciences and Disorders, Salt Lake City,
UT 84112-0252 USA. Study 2: It's a case of miscommunication with catastrophic consequences. Two human blood cells that help fight blood loss, infection, and inflammation
are responsible as well for starting a series of molecular events that results in overproduction of Cox-2, an enzyme involved in heart attack, stroke, atherosclerosis, and other
inflammatory diseases. The finding by researchers at the University of Utah and Univer sity of South Carolina means scientists may be able to develop drugs to prevent or
lessen the severity of inflammatory diseases, such as atherosclerosis and heart attack.
Discovery of the signaling mechanism will be invaluable in sorting out the roles Cox-2
plays in those diseases, according to Guy A. Zimmerman, MD, University of Utah School
of Medicine professor of internal medicine, senior author of the study detailing the research. "This discovery has immediate clinical relevance," said Zimmerman, director of
the medical school's Program in Human Molecular Biology and Genetics. "This opens the
potential of developing medications for both the prevention of long-term atherosclerosis
(clogged arteries) and the acute events of heart attack." The study, reported in the
Journal of Clinical Investigation online, also was led by Dan A. Dixon, a former member
of Zimmerman's lab now at South Carolina. The researchers identified a biochemical signaling pathway between human blood platelets, cells essential for blood clotting, and
monocytes, white blood cells the body makes to fight inflammation and infection. But,
according to Zimmerman, the biological systems involved in blood clotting and inflamma tion also are related to a host of human diseases. The Utah and South Carolina researchers discovered that the blood platelet signals the monocyte two times, triggering produc tion of Cox-2, an enzyme that helps regulate inflammation. But when blood platelets and
monocytes get their signals crossed, it can lead to overproduction of the enzyme and
result in cardiovascular diseases that strike and kill millions of people worldwide. Zim merman compares the signaling between blood platelets and monocytes to a pair of molecular control switches that turn Cox-2 production on and off. "It's a mechanism for pre cise control of Cox-2 production," he said. "But if one of the switches is turned on too
high or low, it can lead to inappropriate production of Cox-2 in disease." The first signal
from the platelet tells the monocyte to turn on the gene that provides the instructions
necessary to make Cox-2. These instructions are carried in small molecule called messenger RNA. When the blood platelet signals the monocyte, the cell decodes the instruc tions from the Cox-2 gene in a process called transcription. This results in production of
messenger RNA that specifically codes for Cox-2. After the messenger RNA is transcribed, the blood platelet then sends a second signal to the monocyte that regulates
stability of the Cox-2 messenger RNA and further decoding of the genetic information in
a process called translation. This results in production of the Cox-2 protein and controls
how much, and at what time point, it is produced. Drugs called non-steroidal anti-inflam matory agents, which inhibit production of Cox-2 and reduce inflammation, are some of
the most widely used medications in the world for arthritis and other inflammatory dis eases. But some of these drugs, also called Cox-2 inhibitors, such as Vioxx, increase the
chance of heart attack. Study 3: According to recently published research from the
United States, cholesteryl oligoArg delivering vascular endothelial growth factor (VEGF)
small interfering RNA (siRNA) effectively inhibits tumor growth in colon adenocarcinoma.
"VEGF is a multifunctional angiogenic growth factor that is a primary stimulant of the de velopment and maintenance of a vascular network in the vascularization of solid tumors.
It has been reported that a blockade of VEGF-mediated angiogenesis is a powerful method for tumor regression. "RNA interference represents a naturally occurring biological
strategy for inhibition of gene expression. In mammalian systems, however, the in vivo
application of small interfering RNA (siRNA) is severely limited by the instability and poor
bioavailability of unmodified siRNA molecules," wrote W.L. Kim and colleagues, University
of Utah. "In this study, we tested the hypothesis that a hydrophobically modified protein
transduction domain, cholesteryl oligo-D-Arg (Chol-R9), may stabilize and enhance tu mor regression efficacy of the VEGF-targeting siRNA. The noncovalent complexation of a
synthetic siRNA with Chol-R9 efficiently delivered siRNA into cells in vitro. "Moreover, in a
mouse model bearing a subcutaneous tumor, the local administration of complexed VE GF-targeting siRNA, but not of scrambled siRNA, led to the regression of the tumor," reported the authors. The researchers concluded, "Hence, we propose a novel and simple
system for the local in vivo application of siRNA through Chol-R9 for cancer therapy."

New research, "The vascularisation of oral cavity tumours and tumour shell tissue
determined by three-dimensional power Doppler sonography," is the subject of a report.
"The aim of the study was to determine and quantify the vascularity of oral cavity tu mours and peritumoural tissue by using 3-D power Doppler sonography (3-D PDS) and
to compare the vascularity of metastatic and nonmetastatic tumours. The investigation
was carried out preoperatively on 49 patients with squamous carcinoma of the tongue
and floor of the mouth," investigators in Maribor, Slovenia report. "Collected data were
analysed with the help of virtual program of computer-aided analysis (VOCAL)-imaging
program by which the borders of a structure could be defined and vascularity quantified
by analysing 3D colour histograms. Vascularity was defined by three indices, VI-vascular isation index, FI-flow index and VFI-vascularisation-flow index. The vascularity of oral
cavity tumours was determined in 4 mm and 7 mm shells surrounding the tumour. Modi fied neck dissection was performed in all of the patients and lymph nodeswere examined
histologically. Peritumorous tissue vascularity was significantly higher in metastatic (N+
neck) than it was in nonmetastatic (N0 neck) tumours. Indices VI and VFI in 4 mm and 7
mm shells differed significantly between N+ and N0 tumours (p <0.01). Flow index (FI)
did not show any difference between N0 and N+ necks. The difference between vascularity indices VI and VFI of peritumorous tissue and tumor was also varied significantly
between N0 and N+ neck (p <0.05) and was higher in N+ tumours. With VOCAL software and 3-D power Doppler sonography, the vascularity of peritumorous tissue could be
quantified successfully," wrote J. Rebol and colleagues, University Hospital. The research ers concluded: "Tumours which had metastasised showed richer vascularity in their shells
and a greater difference in vascularity between the shell and tumor tissue." Rebol and
colleagues published their study in Ultrasound In Medicine and Biology (The vascularisa tion of oral cavity tumours and tumour shell tissue determined by three-dimensional

TEXT:
A new study, "Noradrenergic projections to the song control nucleus area X of the
medial striatum in male zebra finches (Taeniopygia guttata)," is now available. According
to recent research from the United States, "There is considerable functional evidence implicating norepinephrine in modulating activity in the vocal control circuit of songbirds.
However, our knowledge of noradrenergic inputs to the song system is incomplete." "In
this study, cholera toxin subunit B (CTB) injections into area X revealed projections from
the noradrenergic nuclei locus coeruleus and subcoeruleus, and injections of biotinylated
dextran amines into these noradrenergic nuclei labeled fibers in area X. The nonreciprocity of this connection was demonstrated by the absence of retrogradely labeled cells in
area X following injections of CTB into the locus coeruleus. Additionally, we found novel
inputs to area X from the nidopallium and arcopallium, the mesencephalic central gray,
and the dorsolateralis anterior (DLL) and posterior (DLP) lateralis in the thalamus. Area X
can be clearly distinguished from the surrounding medial striatum based on cytoarchitec tural and chemical neuroanatomical criteria. We show here that neuromodulatory inputs
to area X however, exhibit a considerable degree of overlap with the surrounding area.
This finding suggests that regional specificity in neuromodulator action is most likely af forded by a specialization in receptor density and enzyme distribution rather than projec tions from the synthesizing nuclei. Our results extend current knowledge about noradrenergic projections to specialized nuclei of the song control circuit and provide
neuroanatomical evidence for the functional action of norepinephrine-modulating context-dependent ZENK expression in area X," wrote C.B. Castelino and colleagues, Johns
Hopkins University. The researchers concluded: "Furthermore, the novel projections to
area X from telencephalic and thalamic areas could be new and interesting nodes in the
striatopallidothalamic loop spanning the songbird brain." Castelino and colleagues pub lished their study in the Journal of Comparative Neurology (Noradrenergic projections to

"High levels of factor XI have been implicated as a risk factor for deep venous thrombosis and possibly cardiovascular disease; however, the relationship between elevated factor
XI activity and stroke has yet to be established." D.T. Yang and colleagues at University
of Utah wrote, "We retrospectively evaluated factor XI activity, factor XI antigen, and
high-sensitivity C-reactive protein (hs-CRP) values in samples from 65 patients with
stroke, 13 with transient ischemic attack (TIA), and 17 with venous thrombosis, younger
than 55 years with normal prothrombin and partial thromboplastin times who underwent
evaluation for a hypercoagulable state." "Factor XI activity levels were more than normal
in 22% of patients with stroke or TIA and 18% of patients with venous thrombosis, producing odds ratios of 5.3 and 4.1 for stroke or TIA and venous thrombosis, respectively,"
the scientists noted. "Factor XI activity levels correlate with factor XI antigen levels by
Deming regression analysis (slope, 1.3; R=0.667) and a lack of correlation of both with
hs-CRP suggests that factor XI is not an acute phase reactant." The researchers concluded, "Our findings suggest an association between elevated factor XI activity and
stroke." Yang and colleagues published their study in the American Journal of Clinical
Pathology (Elevated factor XI activity levels are associated with an increased odds ratio
for cerebrovascular events. Am J Clin Pathol, 2006;126(3):411-415). For additional information, contact G.M. Rodgers, University of Utah Health Sciences Center, Dept. of

distinguished professor of biology. "I'm a basic researcher, so it was both unexpected and
gratifying for our basic research to have medical applications. We certainly didn't expect
that when we got started. We just wanted to understand why cone snails were capable of
killing people in certain circumstances. We never dreamt at the time it would have some
direct medical application. I'm very, very pleased." Olivera was among 65 new members
and five foreign associates elected to the Institute of Medicine, the organization an nounced Monday. "It is a great pleasure to welcome these distinguished and influential
individuals," said Institute of Medicine President Harvey V. Fineberg. "Members are elec ted through a highly selective process that recognizes people who have made major contributions to the advancement of the medical sciences, health care and public health.
Election is considered one of the highest honors in the fields of medicine and health."
Election to the institute is Olivera's second big honor this year. In April, he won a fouryear, $1 million award as one of 20 new "Million-Dollar Professors" named by the Howard
Hughes Medical Institute. Olivera grew up in the Philippines, where cone snails were sold
in seafood markets and where fishermen occasionally were stung by the snails and killed
by their venom. Cone snails harpoon fish with a hypodermic needle-like tooth, injecting
venom that is toxic to the nervous system, paralyzing fish so they can be reeled in and
eaten. Olivera and members have his lab have identified several promising drug candid ates in the snails' nerve poisons. Prialt, sold by Ireland's Elan Corp., is pumped into fluid
surrounding the spinal cord to treat chronic, intractable pain suffered by people with can cer, AIDS, injury, failed back surgery or certain nervous system disorders. This article

University of Bern, Switzerland, describe new medical findings. This trend article
about University of Bern, Switzerland, is an immediate alert from NewsRx to identify developing directions of research. Study 1: Research findings, "Vocal cord dysfunction:
dealing with aggressivity," are discussed in a new report. According to recent research
from Bern, Switzerland, "QUESTIONS UNDER STUDY: Vocal cord dysfunction (VCD) is
characterised by recurrent attacks of paradoxical adduction of the vocal cords during inspiration, accompanied clinically by dyspnoea attacks with inspiratory stridor lasting
between minutes and hours. The aim of the study is to evaluate the self-perception of
patients suffering from VCD and how they deal with aggressivity." "The Giessen Test (GT)
and the Picture Frustration Test (PFT) were used on 6 patients with VCD. Five variables
show significant differences between the patients with VCD and the values of the norm ative groups. VCD-patients show an idealized image of themselves, ie relaxed, open, so ciable, and capable of devotion. They do not reject accusations against them by others
and rarely make self-criticism. In conflicts they behave passively, thus blocking their ex pression of aggressivity. In many cases organic disposition and trigger stimuli are
thought to be responsible for provoking dyspnoea attacks in VCD. However, the self-perception of patients and their way of dealing with aggressivity strongly suggests that
psychosocial factors play a great role in the development of VCD," wrote E. Seifert and
colleagues, University of Bern. The researchers concluded: "This requires not only symptom-orientated therapy but also psychological counselling." Seifert and colleagues pub lished their study in Swiss Medical Weekly (Vocal cord dysfunction: dealing with aggressivity. Swiss Medical Weekly, 2007;137(7-8):127-9). For additional information, contact E. Seifert, University of Bern, Division of Phoniatrics, ENT-Clinic, Head and Neck Sur gery, Bern, Switzerland. Study 2: Pelvic lymph node dissection (PLND) is warranted in
prostate cancer patients undergoing radical prostatectomy with a serum level of PSA <10
ng/ml. "Controversy persists concerning the role of PLND in patients with preoperative
PSA values <10 ng/ml undergoing treatment for prostate cancer with a curative intent.
The aim of this study was to determine the incidence of lymph node metastasis in this
subgroup of patients," scientists in Switzerland reported. "Patients with clinically localized
prostate cancer and a serum PSA <10 ng/ml, without neoadjuvant hormonal or radiotherapy, with negative staging examinations who underwent radical retropubic prostatec tomy with bilateral extended PLND and with greater than or equal to10 lymph nodes detected by the pathologist in the surgical specimen, were included in the study," explained
M.C. Schumacher and colleagues, University of Bern. "A total of 231 patients with a me dian serum PSA of 6.7 ng/ml (range 0.4-9.98) and a median age of 62 years (range 4476) were evaluated. A median of 20 (range 10-72) nodes were removed per patient.
Positive nodes were found in 26 of 231 patients (11%), the majority of which (81%)
had a Gleason score greater than or equal to7 in the surgical specimen. "Of the patients
with a Gleason score greater than or equal to7 in the prostatectomy specimen 25% had
positive nodes, whereas only 3% with a Gleason score less than or equal to6
were node positive. The incidence of positive nodes in patients with clinically localized
prostate cancer, a serum PSA <10 ng/ml and a Gleason score greater than or equal to7
in the prostatectomy specimen was 25% after extended PLND," informed the team. The
researchers concluded, "It seems that in this patient group extended PLND, including re moval of nodes along the internal iliac vessels, is warranted." Schumacher and colleagues published their study in
n European Urology (Is pelvic lymph node dissection necessary in patients with a
serum PSA <10 ng/ml undergoing radical prostatectomy for prostate cancer? Eur Urol,
2006;50(2):272-279). For more information, contact U.E. Studer, University of Bern,
Dept. of Urology, CH-3010 Bern, Switzerland. Study 3: Apolipoprotein B is a long-term
predictor of mortality in type 1 diabetes mellitus. According to a study from Switzerland,
"To evaluate the association of apolipoprotein B (apo B) with mortality due to all causes,
to cardiac disease and to ischaemic heart disease (IHD) in subjects with type 1 diabetes
mellitus. 165 subjects with type 1 diabetes included in the Swiss Cohort of the WHO Mul tinational Study of Vascular Disease in Diabetes were followed for 14.7+/-0.45 years.
Causes of death were obtained from death certificates, hospital records and postmortem
reports." "Using a parametric proportional hazards model the association of apo B with
mortality rates was assessed by time-to-event analysis, including the absolute cumulat ive mortality risk over time for various apo B levels at baseline," wrote C. Stettler and
colleagues, University of Bern. They discovered, "Apo B was positively associated with
all-cause mortality [hazard ratio (HR) 2.65 per g/L increase of apo B, 95% CI: 1.116.36, p=0.029], cardiac mortality (HR 11.64, 1.03-131.11, p=0.047) and IHD mortality
(HR 9.36, 1.26-69.66, p=0.029). An apo B greater than or equal to0.96 g/L translated
into a duplication of overall mortality hazard (HR 1.93, 1.00-3.72, p=0.050), and a sevenfold increase of mortality because of cardiac disease or IHD (HR 7.44, 1.44-38.42,
p=0.017 and HR 7.38, 0.78-69.82, p=0.081). "A baseline apo B of 1.5 g/L predicted an
absolute cumulative risk to die over the next 10 years of 12.1% (5.2-31.7) for male and
of 10.4% (4.7-26.1) for female subjects whereas risks were 6.3% (1.8-21.4) and 5.4%
(0.8-15.8) for an apo B of 0.8 g/L." The researchers concluded, "Apo B is consistently
associated with an increased mortality in type 1 diabetes." Stettler and colleagues pub lished the results of their research in the Journal of Internal Medicine (Apolipoprotein B
as a long-term predictor of mortality in type 1 diabetes mellitus: a 15-year follow up. J
Intern Med, 2006;260(3):272-280). For additional information, contact C. Stettler, University of Bern, Inselspital, Division Endocrinol & Diabetes, CH-3010 Bern, Switzerland.

Data detailed in "Safety and efficacy of surgical management of hyperthyroidism:
15-year experience from a tertiary care center in a developing country" have been
presented. According to a study from India, "Ideal management of toxic goiter still re mains elusive. Though surgical management of toxic multinodular goiter (MNG) is well
accepted, surgical treatment of Graves' disease (GD) is still controversial in view of the
presumed increased incidence of complications." "In this paper, we discuss the experience of the surgical management of hyperthyroidism at a specialized tertiary care endocrine center in a developing country, highlighting the minimal morbidity and satisfactory
outcome in experienced hands. We retrospectively reviewed 325 consecutive patients
with hyperthyroidism managed surgically from 1990 to 2005. The etiologic diagnoses
were Graves' disease (185), toxic MNG (105), and autonomously functioning
thyroid nodules (AFTN) (n=35). The indications for surgery in Graves' patients were
large goiter, relapse after antithyroid drug therapy (ATD), Graves' ophthalmopathy, and
presence ofnodule. The indications for surgery in toxic MNG were retrosternal extension
(n=15), compressive symptoms (n=20), and large size (grade II). Among the
AFTN nodule size, those greater than 4 cm (85%) formed the major indication for surgery. Subjects with GD and toxic MNG were subjected to subtotal thyroidectomy (n=93
prior to 1995) or total thyroidectomy (n=205 post-1995). Hemithyroidectomy was the
procedure of choice in patients with AFTN. Patients with Graves' disease were younger in
age, with shorter mean duration of goiter when compared with the other 2 groups. Eight
percent of patients with Graves' disease without a clinically palpable nodule and 25% of
those with nodules had associated differentiated carcinoma, including papillary, follicu -
lar, and medullary thyroid cancer. Four percent of patients with toxic MNG had malig nancy. Complications included temporary hypocalcemia (24%), permanent hypocalcemia
(3%), and permanent vocal-cord palsy (1%). Surgery for hyperthyroidism has negligible
mortality and acceptable morbidity in experienced hands. It is a definite option in selec ted cases. Immediate and permanent cure of hyperthyroidism is achieved, with no recurrences, after total thyroidectomy," wrote P.V. Pradeep and colleagues, Sanjay Gandhi
Postgraduate Institute of Medical Sciences. The researchers concluded: "The cosmetic
outcome is good, with excellent patient satisfaction and acceptance." Pradeep and col leagues published their study in World Journal of Surgery (Safety and efficacy of surgical
management of hyperthyroidism: 15-year experience from a tertiary care center in a developing country. World Journal of Surgery, 2007;31(2):306-12; discussion 313). For

Investigators publish new data in the report "Glottal function index: a predictor of
glottal disorders in children. Hyperkinetic laryngeal behaviors may be used to achieve
glottal closure in the presence of vocal cord disorders. In adults, the Glottal Function Index (GFI) is a validated self-administered survey used to evaluate glottal insufficiency,"
researchers in Israel report. "In children, the relationships between glottal closure
and vocal cord lesions have not been examined. We undertook to evaluate the efficacy
of the GFI in detecting disorders of the vocal cords in children. We evaluated 100 consecutive children who underwent flexible fiberoptic laryngoscopy. A 4-item GFI question naire was administered to the parents of each study subject on study entry. The video tapes of the examinations were evaluated and scored by 3 investigators in a blinded
manner. The GFI scores were compared in subjects with and without vocal cord findings.
The final analysis included 100 children 2 to 16 years of age. The-mean age of the study
group was 7.3 years (+/-3.9 years). Of the 100 patients, 54 had vocal cord disorders.
The most common was vocal cord nodules, in most cases combined with bowing of
the vocal cords; the two variables were highly correlated (p <<.01). We performed a receiver operating characteristics test between the presence of vocal cord disorders and
the GFI score. We found that the "optimal" score, on which the sensitivity and specificity
curves cross, was 3. Of the 54 patients who had vocal cord disorders, the index identified 38 patients (70%), whereas the patients' complaints identified only 30 patients
(55.6%). This difference was statistically significant (p <.05)," wrote J.T. Cohen and col leagues, Tel-Aviv University. The researchers concluded: "The GFI is a reliable 4-item
symptom index with excellent correlation to the presence of vocal cord lesions in children." Cohen and colleagues published their study in Annals of Otology, Rhinology &

Current study results from the report, "Evolution of vocal fold nodules from childhood to adolescence," have been published. "Bilateral (quasi) symmetrical lesions of the
anterior third of the vocal folds, commonly called vocal fold nodules (VFNs) are the
most frequent vocal fold lesions in childhood caused by vocalabuse and hyperfunction.
This study evaluates their long-term genesis with or without surgery and voice therapy,"
investigators in Antwerp, Belgium report. The researchers concluded: "" Bilateral (quasi)
symmetrical lesions of the anterior third of the vocal folds, commonly called vocal fold nodules (VFNs) are the most frequent vocal fold lesions in childhood caused
by vocal abuse and hyperfunction. This study evaluates their long-term genesis with or
without surgery and voicetherapy. A group of 91 postmutational adolescents (mean age,
16 years), in whom VFNs were diagnosed in childhood, were questioned to analyze the
evolution of their complaints. Thirty four of them could be clinically reexamined by
means of the European Laryngological Society-protocol, including a complete laryngolo gical investigation and voice assessment. A total of 21% of the questioned group (n=91)
had voice complaints persisting into postpubescence with a statistically significant differ ence (p <or=0.001) between boys (8%) and girls (37%). VFNs were still present in 47%
of the girls and 7% of the boys of the clinically evaluated group (n=34). Analysis of the
data before and after puberty shows that the variables gender, allergy, and degree of
dysphonia ("G") in childhood enable a fairly correct prediction of persisting voice complaints in adolescence (sensitivity of 89% and specificity of 67%). The results of this
study show a clearly different evolution for both sexes, with significant higher long-term
risks for dysphonic girls with allergy." De and colleagues published their study in the

Investigators at University of Utah publish new data on behavior in children
LANGUAGE: English
WORD COUNT: 389
TEXT:
Fresh data on behavior are presented in the report "Behavioral characteristics of children with vocal fold nodules." According to recent research published in the Journal
of Voice , " Vocal fold nodules (VNs) in children are benign, bilateral lesions occurring
on the mid-membranous vocal folds. Repetitive phonotraumatic behavior leading to
chronic vocal fold injury and repair is frequently cited as the primary etiology; however,
specific behavioral characteristics may predispose some children toward intense and po tentially phonotraumatic voice use, thereby contributing secondarily to VN formation."
"The purpose of this case-control study was to determine whether children with VNs possess unique behavioral characteristics that may predispose them to VN development.
Parents of 26 children with VNs (20 boys, 6 girls, mean age=7.2 years, SD=2.5 years),
and 29 vocally normal, medical controls (22 boys, 7 girls, mean age=6.7 years,
SD=2.4), completed the Childhood Behavior Checklist (CBCL/4-18, Achenbach, 1991), a
standardized parent-rating scale with strong psychometric properties. No significant
between-group differences were detected on any of the behavior problem syndrome
scales. Group differences approached significance for the individual items "screams a lot"
and "teases a lot" (VN group >Controls). The VN group scored significantly higher than
the controls on the "Social Scale," a compilation of positive ratings of the child's social
activity, frequency of contacts with friends, behavior with others, and behavior by them selves," wrote N. Roy and colleagues, University of Utah. The researchers concluded:
"Observed outcomes were consistent with previous characterizations of children with VN
as "outgoing" or "extroverted" but were not consistent with other claims that this popu lation may be at risk for "aggressive, attentional," or "impulsive" behavior problems."

Fresh data on radiation are presented in the report "Vascular evaluation in laryngeal

recent report, researchers in Nagoya, Japan conducted a study "To determine the efficacies of 2 methods for evaluating vascular changes in laryngeal diseases. Prospective
comparative study.".
"University hospital. Twenty-four adults planning to undergo laryngomicrosurgery for
unilateral lesions in their vocal cords. Vascular evaluation was performed using contact
endoscopy and laser Doppler flowmetry during laryngomicrosurgery. Morphological and
physiological variables of the vascular changes. Contact endoscopy examinations re vealed changes in the fine vascular network patterns in the vocal cords. Hypervascularity was present in patients with polyps but not in those with nodules, and the degree of
vascularity was variable in patients with malignant neoplasms. Patients with papillomas
and patients in the postradiation therapy group showed hypovascularity with losses in
the capillary network. Laser Doppler flowmetry revealed high mean blood flows in patients with polyps, dysplasia, and malignant neoplasms, whereas patients with papillo mas and those in the postradiation therapy group had low blood flows," wrote M. Sone
and colleagues, Nagoya University, Department of Otorhinolaryngology.
The researchers concluded: "The variables measured by laser Doppler flowmetry and
endoscopy were strongly correlated. Evaluations of morphological and physiological
changes of vascularity in laryngeal diseases are important for understanding their patho physiology, and combining contact endoscopy and laser Doppler flowmetry is useful in
such evaluations."

Research findings, "Total thyroidectomy for the treatment of thyroid diseases in an
endemic area," are discussed in a new report. According to a study from Athens, Greece,
"Thyroidectomy is a common operation with very low mortality and an acceptable morbidity rate. Total thyroidectomy has become the predominant type of surgery used today
for the treatment of thyroid diseases.".
"In this retrospective study, we analyzed the complications of thyroid surgery according to the operative technique used in our department. A retrospective analysis was per formed for all patients who underwent thyroid surgery during the previous 11 years. The
period under study was divided into two sections: phase A (1995-1999) and phase B
(2000-2005). Patient characteristics, type of operation, histologic diagnoses and postoperative complications were compared in the two study periods according to the type of
surgery. A total of 264 patients between the ages of 18 and 89 underwent thyroid surgery during the study period (133 in phase A and 131 in phase B). Overall histopatholo gical diagnoses were nodular goiter (54.9%), hyperplastic nodules (14.7%), adenoma
(8.3%), thyroid cancer (18.2%), and Hashimoto thyroiditis (3.8%). Total thyroidectomy
was performed in 91 patients in phase A versus 115 patients in phase B (p <0.001),
whereas the use of subtotal thyroidectomy and lobectomy decreased over time. A trend
toward increased morbidity was noted in phase B. Seven patients had hypocalcemia in
phase A, whereas 11 patients had hypocalcemia in phase B. Similarly, 5 patients had
some degree of vocal cord paralysis in phase A, compared with 7 in phase B (p >0.05).
Morbidity was significantly increased in the case of cancer or reoperation. Despite the
slightly higher risk of complication associated with total thyroidectomy, this has gradually
replaced more conservative approaches for the treatment of both benign and malignant
thyroid diseases," wrote E.P. Misiakos and colleagues, University of Athens, Department
of Surgery.
The researchers concluded: "Reoperations and surgery for thyroid cancer carried a
higher risk of complications."
