DE-RECOGNITION OF BADC CREATES UNCERTAINTY
Future of 50 BDS (final-year)
students in jeopardy
By Our Special Correspondent
KARACHI - As many as 50 BDS (finalyear) students - 37 girls and 13 boys of Bibi Aseefa Dental College (BADC),
Larkana, have been running from pillar
to post to get their examinations
scheduled which had already been
delayed by more than two months owing
to an uncertain situation reportedly created
by PMDC's recent circular whereby
affiliation of the college has been
suspended.
According to the affected students, the college
administration was not in a position to announce
the date of their final-year exams unless and
until they get a green signal from the PMDC
vis-à-vis recognition of their college.
However, principal of the college has assured
us that he was trying his best to arrange the

PMDC team's visit to the college as soon as
possible so that he could conduct their exams
in October, they added.
Voicing their concern over inordinate delay in
their exams, the perturbed students said that
not only they but even their parents are also
highly disturbed over the news of de-recognition
of their college by the PMDC.
They were of the opinion that the college
administration should immediately meet
the PMDC's requirement of appointing
associate professors of different subjects
in the college for final-year BDS students.
"At present we have lecturers of certain
subjects but not associate professors,"
they deplored.
Ilyas Sheikh, when contacted by Dental
News said that a team of PMDC which
undertook its third visit to the college on
Dec 15, 2014, through a letter (dated Aug
28, 2015) informed that the college had been
recognized. But the recognition of the college

ISLAMABAD - Thousands of Pakistani doctors
face a threat of a comprehensive ban on practice
and study in the United States and Europe in the
wake of IAMRA's (International Association of
Medical Regulatory Authorities) repeated warnings
to the PMDC that it should help improve the quality
of medical education and close down all illegal
medical colleges in the country.
According to media reports, the IAMRA had, a few
months, back asked the PMDC to improve the
quality of medical education and shut all illegal
medical colleges.
The IAMRA had reportedly warned that in case of
non-compliance, it would ask the governments of
the United States and all the European countries
to impose a ban on the Pakistani doctors' work or
study in their respective countries.
Confirming that that the IAMRA had issued the
warning, PMDC president Prof Shabbir Lehri said
that the Council fought the case before the IAMRA
and got one-year relaxation for improving the quality
of medical education in the country.

World Hepatitis Day
observed countrywide
DN Report
KARACHI - The World Hepatitis Day
was marked in Pakistan as elsewhere
in the world with a pledge to spread
awareness for prevention, control and
treatment of this deadly disease.
On World Hepatitis Day, 28 July 2016,
the World Health Organization (WHO)
sets out this year's theme, "Know
hepatitis - Act now", with an objective
to sensitize policy-makers, health
workers and the public know about
the infection, know their status by
getting tested, and finally seek
treatment to reduce needless deaths
from this preventable and treatable
infection.
Activities such as walks, seminars and
free medical camps were held around
the country to improve public
knowledge relating the risk of hepatitis,
and enhance access to tests of
hepatitis and treatment services so as
to help eradicate the dreadful disease
hepatitis which is fully preventable and
treatable disease.
Viral hepatitis - known as hepatitis A,
B, C, D, and E - affects millions of
people worldwide, causing acute and
chronic liver disease.

Liver cancer assuming alarming proportion
DN Report
KARACHI - Vice
President of Pakistan
Society for the Study of Liver Diseases
(PSSLD), Dr. Ziagham Abbas said
here that liver cancer is the fifth most
common cancer globally accounting
for 600,000 new cancer cases annually
and major burden of this disease lies
in the developing countries.
This, he said, while addressing an
awareness seminar organized by Pakistan
Society for the Study of Liver Diseases in
connection of the World Hepatitis Day
observed on July 28 every year across
the globe.
Dr Zaigham said about 10,000 new liver cancer
cases reports every year in Pakistan and
incidents of such cases are growing rapidly
in developing countries. He said liver cancer
cases are more common among males across
the world. He said in Pakistan, it can affect
six (06) per 100,000 males and four (04) per
100,000 females.
He said liver cancer tends to occur in livers
damaged most commonly by chronic infections
such as hepatitis B and C. "Contaminated and
improperly stored grains and spices may be
a contributing factor in causing liver cancer,"
he added.
He said many liver cancers could be prevented
by reducing exposures to known risk factors.
He said vaccine to prevent hepatitis B is
available but there is no vaccine for hepatitis
C.
He said these viruses can spread through
sharing contaminated needles and syringes,
reusing unsterilized equipment for surgical
and dental procedures, improperly screened
blood transfusion, and through childbirth.
He suggested people at high risk for hepatitis
B or C should be tested for these infections
so they can be treated, if required.
PSSLD's founding president Prof Dr Wasim
Jafri said there are 400 million people in the
world who live with chronic hepatitis B. He
said hepatitis B transmitted throughout blood,
unnecessary use of needles and from an
infected mother to her newborn baby during
delivery.
He said hepatitis B which reportedly affects
3pc of the population in Pakistan is dangerous
because it is a "silent infection". He said most
people infected with hepatitis B are unaware
of their infection and can unknowingly pass
the virus to others through their blood and
infected bodily fluids.
Quoting a recent survey, speakers said
hepatitis B and C are major public health
problems for
Pakistan with an estimated 20 million people
affected. Both infections can eventually result
in severe liver disease, and in many cases

unchecked. "In the later stages, these
infections are life threatening and become
largely untreatable," they said and added:
"Unfortunately, most patients with end stage
liver disease and liver cancer are in the prime
of their lives and often the main bread earners
for the family."
They further said there have been major
advances in the treatment of hepatitis B and
C virus infections in recent times. In most
patients hepatitis B can be effectively controlled
and hepatitis C can be completely cured with
the currently available treatments.
They said prevention course is the key to
reduce the overall disease burden. Main steps
include the wide use of hepatitis B vaccine,
provision of safe blood and use of sterile
needles, surgical instruments, razors, and
raising public awareness across the country.
Prof Saeed Hamid, Prof Masood Siddiq, Prof
S.M. Munir, Prof Masroor Ahmed, Prof Jameel
Ahmed and others also spoke on this occasion.

Sugar: Should we keep it or eliminate
it from our diet?
S
ugar seems to have developed a
reputation as the big bad wolf in
relation to health. Numerous
studies associating sugar intake with
increased aging, cardiovascular disease,
obesity and even cancer had been
reported in past years. Such research
has led to many health experts around
the globe calling for reductions in
recommended sugar intake, with some
saying we should cut out sugar
completely. But is it really that bad for
our health?
to halve their recommended daily free sugar
intake from 10% to 5%.
"The objective of this guideline is to provide
recommendations on the consumption of free
sugars to reduce the risk of non-communicable
diseases in adults and children," WHO
explained, "with a particular focus on the
prevention and control of weight gain and
dental caries."
Biochemist Leah Fitzsimmons, of the University
of Birmingham in the UK, told;
"Cutting all sugar from your diet would be
very difficult to achieve. Fruits, vegetables,
dairy products and dairy replacements,

Some of these sugars, such as glucose, fructose
and lactose, occur naturally in fruits, vegetables
and other foods. But many of the foods we
consume contain "added" sugars - sugar that

flavor or sugar that has been added to a

The most common sources of added

pathways associated with obesity and diabetes.
What is more, they found long-term
consumption of artificial sweeteners was
associated with increased weight, abdominal
obesity, higher fasting blood glucose levels
and increased glycosylated hemoglobin levels.
"Together with other major shifts that occurred
in human nutrition, this increase in artificial
sweetener consumption coincides with the
dramatic increase in the obesity and diabetes
epidemics," the authors note. "Our findings
suggest that artificial sweeteners may have
directly contributed to enhancing the exact
epidemic that they themselves were intended
to fight."

healthy?
A 2013 study published in The American
Journal of Clinical Nutrition suggested that
consumption of sugar-sweetened beverages
increases weight gain in both children and
adults, while a review paper from the World
Health Organization (WHO) notes an increase
in the consumption of such beverages
correlates with the increase in obesity.
Instead of steering
away from sugar
completely, many
health experts
believe it can be
consumed as part
of a healthy diet,
with some noting
that sugar also has
benefits.
Sugars can often help to make certain
nutritious foods more palatable, which can
promote variety in a healthy, balanced diet."
The American Heart Association (AHA) - who
recommend women should consume no
more than 100 calories a day (6 tsps) and
men should consume no more than 150
calories a day (9 tsps) from added sugars disagrees, stating that our bodies do not
need sugar to function properly.
"Added sugars contribute additional calories
and zero nutrients to food," they add. But
even the AHA do not recommend cutting
out sugar completely.
Tips to reduce sugar intake
Health experts recommend reducing sugar
intake to within recommended guidelines.
The AHA provide some tips to help do just
that:
. Cut back on the amount of sugar you may
regularly add to foods and drinks, such as
tea, coffee, cereal and pancakes
. Replace sugar-sweetened beverages with
sugar-free or low-calorie drinks
. Compare food labels and select the
products with the lowest amounts of added
sugars
. When baking cakes, reduce the amount of
sugar in the recipe by a third
. Try replacing sugar in recipes with extracts
or spices, such as cinnamon, ginger, almond
or vanilla
. Replace sugar on cereal or oatmeal
with fruit.

THE aim of the Oral Health
Observatory is to understand
current needs in dental care
related to patients and dental
professionals at different levels:
local (country-wise), regional
and global. It focuses on three
main areas of interest:
behaviour, clinical and dental
practice. Within this context,
FDI acts as global convener in
oral health and invites all its
members to participate.
The information collected will allow
analysis of current needs in dental
care, according to demand,
guidance, policy and funding. This
will help shape the medium-term
planning of professional resources
and oral health systems.
Behavioural and clinical data in
addition to information from the dental
practices are collected directly from
a network of local dentists. National
Dental Associations are responsible
for the recruitment of participating
dentists. This network of general
dental practitioners is responsible for
interviewing and "observing" adults
and children in their country. Data is
collected in a systematic manner using
the same core indicators guaranteeing
its comparability across different
levels.
A pilot project was carried out by three
National Dental Associations in three
countries: Germany, Mexico and The

PMDC sans permanent registrar
DN Report
ISLAMABAD - Pakistan Medical
and Dental Council (PMDC) is
without a permanent registrar
although around eight months
had already elapsed since the
election of the council's
incumbent executive committee.
There is no full-time registrar in
the PMDC since the incumbent,
Dr. Ahmad Nadeem Akbar, was
forced out in January 2013 on
the alleged charges of corruption
and mismanagement.
After Dr. Ahmad's
unceremonious exit, which ran
the organisation into a longdrawn-out litigation, either junior
registrars or deputationists
landed the job on interim basis.
Among them were Pakistan
Institute Medical Sciences
Islamabad's Children Hospital
joint executive director Dr Raja
Amjad Mehmood, PMDC deputy
registrar Dr Shaista Faisal and
former Rai Medical College
Sargodha chief operating officer
Brig (retd.) Hafizuddin Ahmad
Siddiqui.
Currently, PMDC assistant
registrar Syed Azhar Ali Shah
stands in for the permanent
registrar.
Though no one from within the
organisation is understood to be
currently eligible to run for the
prestigious position, Dr Ahmad
insists even now, he 'lawfully'
holds the registrar's office.
He even tried to occupy the
registrar's office in line with the
health services and regulation
ministry's 'favourable notification'
issued shortly after the interim
management was created.
However, the then acting
registrar, Dr Shaista Faisal, got
in the way and foiled the bid by
calling in the police.
Dr Shaista Faisal also lays a
claim to the office but insiders
disagree saying she is shorter in
length of tenure and also in the
bad books of the incumbent
health ministry's bosses for being
part of the previous Dr Asim
Hussain-led 'corrupt' setup at the
PMDC.
Though there is a high likelihood
of an outsider clinching the
position, Dr Ahmad and Dr
Shaista are pulling out all the
stops for becoming the registrar,
especially by drumming up
support for their candidacy from
within the organisation, the health
services and regulation ministry
overseeing it.
Insiders are not optimistic of the
PMDC getting a permanent

registrar in the near future in the
wake of a controversy over the
council's rightful management
following lapse of presidential
ordinance, last year. The
incumbent executive committee
of the PMDC was elected
following promulgation of the
ordinance in April, 2015.
PMDC President Professor
Shabir Lehri insists the
incumbent executive committee
is the organisation's rightful and
lawful management, so it will stay
put.
However, his predecessor, Prof
Masood Hameed, claims that
with the lapse of the August 2015
presidential ordinance, previous
management of the PMDC had
automatically comes into
existence.
Meanwhile, National Assembly
Secretariat's Legislative Branch
has reportedly decided to table
the bill in a joint session of
parliament for approval of the
PMDC (Amendment) Bill 2015
that had been pending before
the Senate for approval for the
last three months or so.
It may be recalled here that the
bill had been approved by the
National Assembly in March this
year.

Loans for hospitals
T
HE State Bank of Pakistan's recent decision of
launching soft loans scheme for private hospitals
empanelled under Prime Ministers National Health
Programme (PMNHP) to upgrade their facilities is,
of course, a commendable move as the ultimate
beneficiaries of the scheme would be the have-nots.
The SBP's soft loan scheme will, on the one hand, help
improve the facilities existing at the healthcare institutions
empanelled under PMNHP and, on the other, provide
better treatment facilities and health insurance to the
poorest segments of the society at affordable rates.
However, it was only possible when the SBP makes it
mandatory for the borrowers to pass on the benefit of
the subsidy to patients.
The PMNHP is not the incumbent government's first
initiative to provide health facilities to the poorest segments
of the population as it had earlier launched a similar
scheme, called Prime Minister's National Insurance
Programme (PMNIP). The former scheme was aimed at
providing inpatient hospitalisation insurance coverage to
3,100 million enrolled beneficiaries and as per its
parameters, the coverage limit was Rs50,000 for
secondary care service and Rs250,000 for tertiary care
for specified diseases.
Highlighting the salient features of the scheme, the SBP
announced that mark-up will be charged at KIBOR+500
basis points (bps), however, borrower will actually pay
six (06) per cent and the difference of the cost of
KIBOR+500 bps will be paid by the federal government.
Under risk mitigation, the government will bear up to five
(05) per cent losses on the portfolio of banks under the
scheme. NBP and FWBL will be the executing agency
while other banks will also be encouraged to participate
in the scheme. The facility for soft loans will be initially
launched in 23 selected districts but would subsequently
be expanded to cover the entire country.
The loans under PMNHP will be offered to private
empanelled hospitals for upgrading their facilities which
include purchase of equipment, operation theatre's upgradation and improvement in emergency services. All
hospitals, clinics, healthcare units empanelled/shortlisted
under PMNHP will be eligible for loans. Besides, qualified
MBBS/BDS doctors from an institution recognised by
PMDC, clinics/hospitals/labs registered with PMDC and
PMA, sole proprietors, partnership firms, private and
public limited companies, other bodies/trusts running
hospitals and empanelled under PMNHP will also be
provided soft loans. Debt-equity ratio will be 80:20 and
the borrowers' contribution of equity could be in the form
of existing assets and property offered as collateral subject
to valuation by banks. Soft loans under PMNHP will be
term loans up to Rs10 million and with maximum tenor
of eight years. Loans will be disbursed in single tranche
but the mode of repayment will be in equal monthly
instalments.

ADVICE FOR DENTISTS
Compliance of UNEP Treaty on Mercury
may become effect by 2017
THE recently adopted United
Nations Environmental
Programme Treaty on
Mercury, known as the
Minamata Convention, is
aimed at protecting human
health and the environment
from the adverse effects of
mercury.
The Treaty was designed to
allow significant flexibility to
account for local circumstances.
This means that each country
can comply with the Treaty in
a unique way and compliance
is likely to come into effect by
2017. Dentists should
communicate with their local
health ministry for the exact
details of their country's
compliance agreements.
This is the first international treaty
to name and include dentistry,
prevention and dental research.
The Minamata Treaty contains the
following provisions to support a
phase-down in the use of
amalgam: (i) Set objectives to
prevent caries thus minimizing the
need for restorations; (ii) Setting
objectives aiming at minimizing
use of amalgam; (iii) Promoting
the use of alternatives; (iv)
Promoting research into alternative
restorative materials; (v) Promoting
training in the use of mercury-free
alternatives; (vi) Discouraging
insurance policies that favour the
use of amalgam; (vii) Encouraging
insurance policies to favour the
use of alternatives to amalgam;
(viii) Restricting the use of dental
amalgam to its encapsulated form;
(ix) Promoting the best
environmental practices to reduce
the release of mercury.
Compliance programmes will need
to be taken up by National Dental
Associations, and we encourage
all practicing dentists to become
involved with their dental
associations to assist in advocacy
for oral health for all. In many cases
countries may already comply with
a number of these provisions but
the Treaty provides an opportunity
to develop and refine the relevant
activities. The improvement and
extension of initiatives to prevent
caries is a clear example of how
the provisions provide a framework
for improvement rather than a
single clear defined end point.
This toolkit is aimed at the clinical
dentist and emphasizes the
implementation of programmes in
health promotion and disease
prevention, how dental amalgam
compares to other direct restorative
materials and best management
practices for amalgam waste. The
toolkit focuses on the best available
practices but recognizes that not
all resources are available in all
regions of the world. Where
appropriate the toolkit indicates
possible alternative approaches.
The FDI World Dental Federation,
collaborating with the World Health
Organization (WHO) and the
International Association for Dental
Research (IADR), played a crucial
role during the negotiations to
balance the need to protect the
environment with the provision of
optimal oral healthcare. The Treaty
goes beyond a simple
recommendation to phase down
the use of dental amalgam and
includes a range of forwardthinking provisions for oral health.
These provisions include improved
oral health promotion and disease
prevention, supporting dental
materials research, and offering
guidelines for best management
practices for amalgam waste.
The FDI, in leading the world to
optimal oral health, presents this
practical informational toolkit to
support clinical dentists worldwide
so they can understand and
comply with the provisions of the
Minamata Convention. The toolkit
includes a range of ways that
individual dentists can adopt
immediately that will allow the best
care of patients and at the same
time to recognize that dentists have
a responsibility to the environment
for a healthy future for all humans
around the globe.
The Minamata Convention was
agreed upon by 147 nations in
January, 2013, opened for
signatures in October 10, 2013
and has 102 nation signatures as
24 DENTAL NEWS / August 2016
of September 2014.
Dental caries, despite being largely
preventable, is the most common
global chronic disease, and is still
the most common chronic disease
of childhood (Peterson, 2009).
Dental amalgam has long been a
safe, effective, durable, and
affordable material to restore
carious teeth. The presence of
mercury in dental amalgam led to
dentistry and the FDI becoming
directly involved with the United
Nations Environmental Programme
negotiations on mercury. The FDI
negotiating team, collaborating with
WHO and IADR, worked hard to
ensure that health and oral health
care would be supported in the
treaty whilst still recognizing the
need to protect the environment.
Specifically, the Minamata
Convention "upholds the use of
dental amalgam as a durable, safe,
effective cavity filling material" and
calls for phasing down amalgam
by supporting prevention and
health promotion (thereby requiring
fewer restorations), encouraging
best management practices for
amalgam waste disposal and
supporting research into alternative
materials.
Mercury levels in the environment
have increased over the last
century largely due to human
activity. Mercury can be
concentrated in the food chain,
particularly in fish and marine
mammals. The town of Minamata,
Japan, after which the Treaty is
named, experienced severe
mercury poisoning disease from
industrial release of methyl
mercury in 1950s. Products,
processes and industries where
mercury is used, released or
emitted are addressed in the
Treaty, and dental amalgam
represents a relatively small but
quantifiable part of the overall
mercury burden. Natural emissions
of mercury into the environment,
such as volcanoes, have always
been present, but human activity
has exceeded natural emissions
over the last 200 years (Bayne, et
al., 2013). Once released, mercury
persists in the environment, and
can be repeatedly mobilized,
deposited and remobilized
between air, water, and soil.
Although the total use and release
of mercury has declined
significantly in many countries in
recent years, the fact that mercury
can be transported by wind and
ocean currents means that it can
only be controlled effectively at a
global level. Environmental
mercury exists in several forms,
and those forms have differing
impacts on humans and the
environment. Methyl-mercury,
which affected the residents of
Minamata, is the most toxic form
of mercury. Dental amalgam
contains mercury that is metallically
bound to silver and other trace
metals. The extremely minimal
release of mercury in various
oxidation states from amalgam
fillings is considered to be far below
the limits set by WHO or other
competent authorities (Bayne, et
al., 2013).
Additionally, dental amalgam waste
is a very small contribution to the
mercury in the environment, while
significant environmental
emissions of mercury occur
primarily from burning coal chloralkali production, artisanal gold
mining and fluorescent light bulbs.
By properly handling amalgam and
amalgam waste, the dental
profession can protect the health
of the environment and still provide
optimal patient care.
Perhaps most importantly, efforts
and success in disease prevention
will diminish the need for
restoration and, therefore, diminish
the waste products of any
restorative material, while
increasing human health through
improved oral health.
Indeed, our leading role in
compliance by the dental
community with the Minamata
Convention will help lead to
positive changes to global oral
health. The commitment to a
phase-down in the use of dental
amalgam in the Minamata
convention is supported by nine
provisions. To be compliant with
the Treaty, governments must
adopt at least two of these
provisions.

Gum disease bacteria linked to esophageal cancer
I
n a new study, researchers proposed
for the first time that Porphyromonas
gingivalis - the bacterium behind
gum disease - could be a risk factor for
esophageal cancer.
Based on studies it was suggested that P.
gingivalis are present in cancerous tissue.
Findings of different studies provided the first
direct evidence that infection could be a novel
risk factor for ESCC, and may also serve as a
prognostic biomarker for this type of cancer.
Researchers found out that levels of both the
enzyme and the bacterial DNA were
significantly higher in the cancerous tissue of
ESCC patients than in surrounding tissue or
tissue of normal controls.
According to the Centers for Disease Control
and Prevention (CDC), every year, around
15,000 people are diagnosed with
esophageal cancer - a cancer that starts in
the esophagus or gullet, the muscular tube
that moves food from the throat into the
stomach.
The researchers found levels of P. gingivalis
were significantly higher in the cancerous
tissue of ESCC patients than in surrounding
tissue or tissue of normal controls
The lining of the esophagus is made of two
kinds of cell, which is why there are two
main types of esophageal cancer:
esophageal adenocarcinoma and
esophageal squamous cell carcinoma
(ESCC). ESCC is more common in
developing countries.
Speculating on possible explanations; ESCC
cells are a "preferred niche" for the bacterium
to thrive in, or infection with the bacterium
somehow spurs the development of the cancer.
If the reason is that the cancer cells offer the
bacterium a niche, then simple antibiotics could
be a way forward for treatment. Another
approach could be to use genetic technology
to target the bacterium and ultimately eliminate
the cancer cells.
The cancer is hard to diagnose
in the early stages. At times
cancer develops rapidly after
diagnosis and prognosis is not
good. The known risk factors for
esophageal cancer include
chemical exposure, diet, heredity
and age - all factors already
common to many other cancers.
36 DENTAL NEWS / August 2016
"It would suggest that improving oral hygiene
may reduce ESCC risk; screening for P.
gingivalis in dental plaque may identify
susceptible subjects; and using antibiotics or
other antibacterial strategies may prevent
ESCC progression."

Central details: Smile renewed Esthetic replacement of anterior
with esthetic Obsidian crown class IV restorations
By Anamaria Muresan, DMD,

In the anterior region where
esthetics are paramount, certain
complications can preclude the
use of all-ceramic material. The
task then becomes finding a
material worthy of the anterior
with the durability to meet precise
standards. Obsidian Lithium
Silicate Ceramic Pressed to
Metal (Prismatik Dentalcraft Inc.;

The result is five times the

PFMs.
A 27-year-old male patient
presented with an old PFM crown
on tooth #9, which had
undergone endodontic treatment
about 10 years prior to address
decay. A darkened margin, visible
due to gum recession on the
facial, posed a distinct problem
for this anterior case. In addition,
the esthetics of the PFM crown
were noticeably inadequate.
To achieve an optimal outcome
in the face of these difficulties,
the first task in the treatment plan
was to match the gingival height

Dental plaque bacteria hitch a ride in blood
to fortify colon cancer
Mouth microbes travel through
the circulatory system to give
tumours at the other end of the
gastrointestinal tract a helping
hand. Belinda Smith reports.
Bacteria that cause dental disease
hijack thebloodstream to travel to
the colon where they latch on to
tumours and help them grow, new
research shows.
Biologists from the US and Israel
discovered that the common
Fusobacterium nucleatum bacteria
uses a protein called Fap2 to stick
to colorectal cancer cells and
shields the tumour from the body's
immune system.
The work, published in Cell Host
& Microbe, may not only give
oncologists a means to block
colorectal tumour growth, but also
a means to deliver cancer-killing
drugs.
Only in the past few years has the
influence of microbes that dwell
in and on our body on the growth
and progression of colorectal
cancer been unveiled.
One particular strain, F. nucleatum,
emerged as an interesting
example. Colon tumours tend to
have lots of the rod-shaped
bacteria stuck to them while the
surrounding tissue is pretty much
bare.
But the bacteria's preferred habitat
isn't the gut - it's the mouth, where
it binds to other microbes to form
blobs called biofilms. These
masses of bacteria are the plaque
that accrues on tooth enamel and
along the gum line and can cause
diseases.
So how does F. nucleatum make
the journey from mouth to colon?
The obvious answer is it's
swallowed and travels through the
gastrointestinal tract, but studies
searching for it in the stomach and
small intestine have largely drawn
a blank.
Jawad Abed and Johanna Emgard
from the Hebrew University in
Israel and colleagues thought the
bacterium may hitch a ride in the
bloodstream. To test this, they
injected fusobacteria into the vein
of mice with colorectal tumours.
They found it didn't matter if the
tumours were precancerous or
malignant - fusobacteria in the
blood sought them out and stuck
on tight, but largely ignored the
surrounding healthy tissue.
The colon of mice without tumours
had no fusobacteria, suggesting
that a tumour is required for the
bacteria to make the jump from
the bloodstream.
Using human and mouse cells,
the team uncovered the sticking
mechanism favoured by
fusobacteria.
A protein hanging off the outside
of the bacterial cell, Fap2,
recognised and grabbed onto a
sugar found on colorectal tumour
cells called D-galactose-?(1-3)-Nacetyl-D-galactosamine (thankfully
shortened to Gal-GalNac).
Previous studies showed that Fap2
is instrumental in helping colorectal
tumour cells fly under the immune
system's radar, too - so allowing
the tumour to grow and the
bacteria flourish.
Poo transplants transfer much
more than bacteria
Gilad Bachrach, also from the
Hebrew University and a senior
author of the study, acknowledges
that the work does have limitations.
For instance, in some mouse
models, colorectal tumours grow
quickly - often within a few months.
In humans, though, tumours tend
to grow over years.
And will brushing teeth more often
help keep the risk of colorectal
cancer risk down?
Bachrach's not sure yet: "Based
on our findings, it's too early to say
whether we can prevent mouth
bacteria from travelling through
blood to the colon and promoting
tumour formation or if some people
are more at risk than others."
