Laser and Light Sources
Laser et sources de lumière
We have come a long way since the first laser was
developed by Maimon and its early use by Dr
leon Goldman in the 1960’s. the early lasers
lacked specificity and risks of treatment often out
weighted the benefits.
since then we have seen the development of
vascular and pigment lasers based on the theory of
selective Photothermolysis. even though we have
many vascular lasers, the treatment of Portwine
stains remains a challenge. We can treat pigmented lesions and tattoos, acne, and fat. the technology is rapidly changing.
il a coulé beaucoup d’eau sous les ponts depuis
la mise au point du premier laser par Maimon et
ses premières utilisations par le Dr leon
Goldman dans les années 1960. les premiers
lasers manquaient de précision et les risques que
comportait le traitement l’emportaient souvent
sur ses avantages.
Depuis ce temps, nous avons vu l’avènement des
lasers vasculaires et pigmentaires, qui fonctionnent selon la théorie de la photothermolyse
sélective. Même si nous disposons de nombreux
lasers vasculaires, le traitement des angiomes demeure un défi.
nous pouvons traiter les lésions pigmentées et les tatouages,
l’acné et les graisses. la technologie évolue rapidement.

A Clinical Outline of Lasers Used to Treat Cutaneous Vascular Lesions
Historical Perspective
the theory of selective photothermolysis (sP) provided
the scientific basis for contemporary laser treatment of
vascular lesions 1, when a
preferentially absorbed wavelength is delivered to a target
chromophore in a pulse duration < it’s thermal relaxation
time (tRt). this achieves
irreversible
thermal injury of
sHARYn lAuGHlin, MD,
microvessels,
where photocouniversity of Ottawa
agulation of blood damages
the endothelium in contact by diffusion without damage to the
adjacent dermis (spatial confinement). A flashlamp pulsed dye
laser (PDl) that met the objectives of sP was shown to be
effective in the treatment of portwine stains (PWs) 2. it became
the cornerstone for the development of new vascular laser systems and is still the standard of care for the treatment of many
vascular lesions. i was introduced to this laser in 1987 during a
preceptorship with Dr O tan, one of the pioneers in clinical
PDl treatment 2, and i acquired a PDl in 1988.
Photobiology
the potential target chromophores in vascular lesions include
oxyhemoglobin (HbO2), de-oxyhemoglobin (Hb), and methemoglobin (Met-Hb). A target chromophore with a high photon
absorption coefficient for the preferred wavelength is selected
after considering the characteristics of the lesion to be treated.
Vessel diameter is then matched to pulse duration – smaller
vessels require shorter exposure times. longer wavelengths
penetrate more and combined with larger spotsizes (less dermal
scattering) can achieve deeper injury. Photocoagulation causes
secondary injury to the endothelial lining from thermal diffusion. the classical clinical endpoint for thermal injury was purpura at the effective fluence. With longer exposure times therapeutic injury can be achieved below, at purpura threshold, or
above. For larger vessels longer exposure times also achieve
irreversible injury through mechanisms other than photocoagulation. the theory of extended sPtl3 uses a pulse duration
longer than the tRt to achieve injury to the vessel wall and
perivascular collagen in the treatment of larger vessels (such
as leg veins), or larger structures (such as a hair follicles)
where the chromophore is not evenly distributed within the
target structure.
Other therapeutic approaches use the greater absorption of certain wavelengths by met-Hb compared to HbO2 at 1.8 X for
595-nm and 3-5 X for 1064 nm 4, 5. new systems deliver therapeutic energy levels in longer exposure times, and 1064-nm in
an extended pulse at a judicious fluence, can achieve irreversible injury of vessels in the deeper dermis and subcutaneous tissue. the conversion of HbO2 to Met-Hb occurs in 1030 milliseconds at optimal fluence and pulse duration 6 and new
dual wavelength platforms exploit this phenomenon. the ‘heat
sink’ effect uses the increased absorption of the 595-nm wavelength by a clot formed after a first laser pass at a fluence above
the purpura threshold. 4 tanghetti et al 7 showed that with fluences above purpura threshold, there is time-dependent
increased depth of injury with a second pass at 595-nm in normal skin. We used these reports as the basis of a new approach
in the treatment of portwine stains, where a second pass with
595-nm at a 20-30 minute interval produces renewed fading in
resistant lesions from deeper and extended injury beyond the
coagulation zone.8
Clinical Considerations
Presently available vascular technology in n. America includes
75 different systems from 22 different manufacturers. the principle of sP should guide the average clinician in selecting the
best approach to treat a specific vascular lesion, and the extended theory is carefully applied to larger vessels. Adhering to the
precepts of sP 1 and the judicious application of extended sP
determines the extent of injury beyond the target chromophore.
in the vascular model a small vessel requires the combination
of fluence, spotsize, and pulsewidth, for heating of blood within the lumen and diffusion only to the endothelium. For larger
vessels, a longer pulsewidth is required to achieve permanent
injury by wider thermal injury possibly through cavitation and
steam bubble formation or thermal denaturation of collagen in
the perivascular cuff.9 As the pulse duration increases the ratio
of stenosis/thrombosis increases with better closure of larger
vessels.10 the thermal injury must still be confined to the target to avoid injury from diffusion to the adjacent or intervening
dermis. Anderson, who founded the theory selective photothermolysis 1 points out that with each new application – one
constant remains – scarring only occurs when the dermis between the targets undergoes necrosis 11. epidermal cooling is an
essential requirement and lowers the risk of adverse effects.
With access to 5 vascular lasers and several iPl systems, the
selection of a treatment option is tailored to the individual
patient and the vascular morphology. the Ontario Ministry of
Health licensed my facility (laserderm) as an iHF in 1991.
each year over 1800 hours of vascular laser surgery are
performed on about 600 patients for insured benign vascular
lesions (mainly malformations and hemangiomas). Another
3000 uninsured treatments are performed on 1000 patients with
all the usual vascular lesions. My personal preferences are
based on this experience over 23 years and the evidenced based
consensus in the published literature.
Portwine stains
Mathematical models confirm that the optimal pulse duration
for the average capillary malformation with a range of vessel
sizes is 1-10 milliseconds.12
• the 585-nm at 0.45 milliseconds PDl is still ideally suited
to treating infantile PWs and small calibre telangiectasia.
• newer yellow light systems use the 595-nm wavelength over
longer exposure times up to 40 milliseconds and achieve

efficacy for larger micro-vessels in mature portwine stains and
for larger capillary telangiectasia. A very light pink PWs in a
child can be treated with 532-nm (green light).
• 25-50% PWs become resistant to treatment. there are several reasons for treatment resistance and incomplete clearance
with green and yellow light. One factor is the limited ability
of short wavelengths to affect ectatic vessels beyond a depth
>2 mm. Multiple passes or pulse-stacking techniques have
been used to improve the extent and rate of fading, but
increased adverse effects have limited this clinical approach.
• near infra-red wavelengths (755-nm and 1064-nm) are being
used more frequently to treat mature, thicker, or nodular purple stains. the 755 nm alexandrite laser can be useful for the
treatment of hypertrophic and treatment-resistant PWs in
adult and pediatric patients 13 and deeper PWs may be treated effectively with the 1064nm nd:YAG laser.14 these methods are best used in experienced hands. the risk of adverse
effects increase despite epidermal cooling, as longer exposure times and increased relative absorption change the paradigm for the mechanism of injury with a smaller therapeutic
margin of safety. the 755-nm wavelength has advantages
over a 1064-nm wavelength.12 the 755 nm absorption coefficient of de-oxyhemeglobin is > that of oxyhemeglobin and
an alexandrite laser likely damages veins more than arteries.
the 1064-nm nd:YAG wavelength is absorbed more by
HbO2 than Hb and damages arteries more than veins. Yang et
al.14 reported that at 1064-nm fluences just above minimal
purpura dose (MPD) can produce extensive deep dermal
necrosis and scarring. the MPD varied greatly among
patients and within a lesion, and since PWs are heterogeneous lesions the narrow range for therapeutic fluence
reduces both efficacy and safety. Formation of met-Hb within the longer exposure times > 10 milliseconds contributes to
greater absorption in blood that may produce uncontrollable
effects. the met-Hb phenomenon is less at 755-nm and still
less at 595-nm.
Hemangioma
the treatment of hemangiomas should be correlated to its natural biologic course and requires a different clinical approach
from a portwine stain.12 Hemangiomas are true tumours, not
malformations like portwine stains. they resemble the fetal
placenta and have cell mediated protection during their growth
phase from the host immune system. involution occurs when
this immune privilege disappears for unknown reasons, and
host cells and enzymes regulating cellular immunity induce
apoptosis within the hemangioma. laser treatment should trigger or assist immune mediated regression and should produce
focal injury in phase with the cellular biology. low fluences in
short pulses best achieves this response and liberates the cells
required for the immune process. it is a mistake to approach
treatment in the same way one treats a portwine stain. Pulsed
dye lasers were never designed to treat even a superficial
hemangioma containing clumps of tangled blood vessels.
these lesions are thicker than portwine stains and beyond the
effective depth for green or yellow light lasers. unlike portwine
stains where dilated small calibre vessels are dispersed within
intervening stroma, hemangiomas are tortuous masses of larger vessels with little or no connective tissue or stroma.
superficial lesions in the early growth stage can be cleared
completely by the flashlamp pulsed dye laser. Adverse effects
can occur, when lasers are used at the same levels as for treating portwine stains, particularly without cryogen cooling of the
epidermis. Our experience indicates that hemangiomas respond
better to yellow (595-nm) or near infra-red pulses (755-nm)at
low energy and short pulses. the PDl is very effective for an
ulcerated hemangioma. i avoid the use of the 1064-nm, which
can be risky even in experienced hands, given the delicate therapeutic balance. Propranolol may become the primary treatment for large complicated hemangiomas and lasers used only
in a supportive role. Aggressive laser therapy with any wavelength at higher fluences is imprudent and should be avoided.
Venous Lesions
Venous malformations can be carefully treated with the deeper
penetrating nd:YAG that reaches the deep components better
than 755-nm. interventional radiology with Bleomycin sclerotherapy is now considered as a primary approach and laser
therapy reserved for residual elements. Venous lakes respond
well to the 1064-nm nd:YAG in 1-3 treatments at 6-8 weeks
apart. the lower absorption in venous blood modulates the
effect of the deeply penetrating wavelength.
Telangiectasia
Fixed erythema and most telangiectasia require green or
yellow light lasers – normal mode 532-nm and 585 or 595-nm.
Although these small capillaries need only relatively short
pulses, purpura-free treatments with longer pulses can lessen
downtime. intense Pulse light (iPl) is a popular choice among
patients, as there is no swelling or bruising, but several treatments are required to achieve similar results as lasers. My personal preferences include:
• iPl for full-face, necks, chest, and hands – any body site, as
this lowers treatment costs and also removes freckles, actinic
dyschromia, lentigines. it is useful for maintenance therapy.
• 532-nm in normal mode for full-face or focal treatments have
erythema and swelling for 3 days but no bruising. it requires
fewer treatments than iPl – usually 2 or 3 – and is useful for
pediatric PWs, fixed erythema, and ulerythema oophryogenes.
• Pulsed dye 595-nm is better for severe cases and larger vessels, but is associated with purpura of smaller vessels for the
best efficacy – usually one treatment. longer pulse exposures
are purpura fee and useful for full-face treatments.
• large purple vessels e.g. on the nose are still best treated
with 595-nm for safety. Many clinicians are tempted to use
the 1064-nm nd:YAG but the Met-Hb effect complicates the
use of longer pulse durations required for a larger diameter
vessel. the greater absorption by HbO2 raises the spectre of
stenosing a feeder arterial vessel with scarring to a wider area
than the skin over the treated vessel. the 755-nm alexandrite
could be a safer choice, in theory, for a capillary with backflow venous contamination.
continued on page 6

• Pyogenic granulomas respond poorly to vascular lasers and
are best removed with a CO2 laser. Avoid the temptation to
use the nd.YAG. Angiokeratomas are difficult to treat, but in
my opinion, the 755-nm alexandrite laser provides the best
option. the rare tufted angiomas does not respond to the PDl.
Summary
With the plethora of vascular laser systems available, the prudent physician learns to apply the principles outlined herein,
and selects a laser to treat a specific vascular abnormality by
matching emission parameters to the characteristics and morphology of the lesion.

Photodynamic Therapy
Photodynamic therapy (PDt)
is a medical treatment used to
treat premalignant lesions
such as actinic keratoses and
Bowen’s disease, early-stage
cancers such as superficial
basal cell carcinomas, and
acne. the concept dates back
to 1913 when the German
physician Friedrich MeyerBetz performed the first studies on his own skin. PDt
requires 3 key components: a
MARtie GiDOn, MD,
photosensitizer that can be

excited by a specific wavelength of light, a light at a wavelength appropriate for the photosensitizer, and oxygen. internal organs may be treated with
intravenous photosensitizers and fibre optic catheters for the
light activation.
two photosensitizers are commonly used for skin, aminolevulinic acid HCl (AlA available as levulan® Kerastick®) and
methyl aminolevulinate HCl (MAl available as Metvix®). the
photosensitizer is applied to the affected area and kept on for 1
to 3 hours, depending on which chemical is used. Metabolically
active cells, such as precancerous, cancerous and sebaceous
cells, differentially take up the chemical. the AlA is converted by the cells to protoporphyrin iX, a photosensitizer. the
affected area is then exposed to a blue or red light for several
minutes to activate the photosensitizer. When the activated photosensitizer and an oxygen molecule are in contact, an energy
transfer takes place that creates an excited singlet state oxygen
radical which destroys the targeted cells. there is usually ery-
activated by the Blu-u® Blue light Photodynamic therapy
illuminator (DusA Pharmaceuticals), intense pulsed light or
pulsed dye laser. MAl (Galderma Canada) is applied as a
cream to similarly prepared skin, occluded for 3 hours to prevent light exposure, and then activated by the Aktilite Cl128
lamp or other red light source. some patients experience pain
during the light treatment and blowing cold air makes them
more comfortable. sunscreen is applied immediately after the
treatment but the patient is advised to avoid visible light as well
as ultraviolet light for the next 48 hours, to avoid excessive activation. After the treatment, patients may experience varying
degrees of discomfort or burning, which can be alleviated by
cold packs. Patients are warned about erythema, peeling and
possible crusting which may last 3 to 5 days. Actinic lesions
require 1 to 2 treatments, about 3 weeks apart. Acne patients
require a series of 5 treatments, 3 to 4 weeks apart. Both treatments provide an excellent cosmetic result.
Laser and Light-based Treatments for Acne
Acne can be a major concern for teens and many adults.
traditionally, we have treated acne with topical medications,
and/or systemic therapy, including antibiotics, hormonal
manipulation and isotretinoin. Alternative treatments with
lasers and light are becoming more attractive, especially with
patients wishing to avoid systemic medication. they can be
used as mono therapy, but are usually used together with topical medication, and oral antibiotics if needed. As the patient
improves, the systemic antibiotics can be discontinued.
P. acnes produces porphyrins, mainly coproporphyrin iii, in the
pilosebacous follicles and are potential targets for photodynamic therapy. On their own, visible blue light at a wavelength
of 405-420 nm and visible red light at 570-670 nm have been
shown to have anti-inflammatory

Laser Safety
HOWAD BARGMAn, MD
toronto
the issue of laser safety is
often overlooked during the
mentoring and learning
process. At past AAD meetings that i have attended, in
spite of numerous laser presentations, there have been
times when none dealt with
the issue of laser safety. in all
the years that i have attended
the Women’s College laser
update, i only recall one 20
minute talk on laser safety.
About 5 years ago i realized
that our laser clinic at sunnybrook Health sciences Centre was
not as compliant with the standards that we should have been.
i undertook to educate myself and after taking a written exam,
qualified as a Certified Medical laser safety Officer (u.s.).
i performed laser safety audits of both hospital and private laser
settings and was surprised at the major deficiencies in these
clinics. Recently, at a south Beach seminar, there was a great
presentation, on screen, of various laser techniques, performed
live by luminaries. All the important laser innovations were
being displayed. this was all taking place in an auditorium
apart from the viewing audience. i noticed immediately that the
operators were wearing protective eye goggles, but their colleagues, and the patients who were waiting, were not, and they
were within feet of the working laser systems. if an accidental
eye injury had occurred, it would have been difficult to defend.
some of the many issues that laser safety addresses are: the
designation and educational requirements of the laser safety
officer where Class 111B and 1V lasers are used (every laser
clinic must have an lsO), credentialing of all staff, fire and
explosion hazards, door signs and locks, plume scavenging (i.e.
smoke evacuation)
Photodynamic Therapy
the Canadian safety standard (CsA) laser safety document, as
it stands now, is licensed from the American standard Ansi
Z163.3-2005. A new Ansi standard will be published by the
laser institute of America before the year end. the CsA is now
debating whether to establish a new ‘made-in-Canada’ laser
safety version which it last did in 1992. if they do, it will be
quite stringent in its recommendations for training and documentation, among many other issues. there are now a couple
of states in the u.s. that will not accept laser training from a
company that sells lasers and this requirement will likely be
copied here in Canada.
Plume scavenging (i.e., smoke evacuation) standards have been
published by the CsA and have become the world standard for
the last couple of years. You should know that any facility that
performs a procedure that produces a plume is obligated to
operate within the parameters set out by this standard. this
includes dermatology suites where cautery is performed.
i remember one day a rabbi asked me if i was observant, and
after i swallowed hard, i answered that i was. He looked at me
and said “Well, we can all do better”. this advice pertains to
protecting our patients, ourselves and our employees from the
potential hazards of lasers.
i encourage questions and can be reached at my e-mail address

10 to 15 minutes. Five treatments, 3 weeks apart are recommended. the patient must avoid light exposure for 48 hours and
usually experiences erythema, peeling and some crusting, lasting about 3 to 5 days.
isolaz photopneumatic therapy is helpful in mild to moderate
acne. it involves a pore cleansing vacuum that empties debris
from the follicles and then pulses a broadband light. lasers at
1450 nm heat the sebaceous glands causing some destruction
and decreased sebum production, but since they do cause
discomfort, they are not often used for acne.
Once acne scarring has occurred, fairly aggressive treatment
is needed for improvement of the scars. Fractional laser treat-

and other strategies for protecting from laser generated airborne contaminants, laser maintenance logs, standard operating
protocols, proper goggles for the laser room, and for outside the
room (this seems to be very important for the Ministry of
Health in Ontario), storage of the laser key when the laser is not
in use, laser type and wavelength signs, warning signs and
labels (warning signs must be removed or turned around when
the laser is not in use), room designs and risks of specular
reflection hazards, development of protocols for laser incidents
and reports thereof, and infection control.
ments are much more popular than the old traditional surgical
dermabrasion or CO2 resurfacing since there is less recovery
time, more predictable results and much less chance of side
effects such as white scars and persistent erythema. Depending
on the patient’s skin type, non-ablative fractional resurfacing
with a few days’ downtime, or ablative fractional CO2 resurfacing with a week’s downtime can be used successfully. three
to 5 treatments, performed 1 to 3 months apart, usually result in
at least a 50% improvement of the scars and additional treatments can be done if desired.

We have had the pulsed dye laser at the CHuMe sainte Justine,
Montreal, Quebec since 1992, and it is an integral part of our
multispecialty vascular anomalies team.1 Port wine stains are
best treated beginning in the first year of life, and will require
at least 6 treatments in most cases, followed by annual followup with laser as needed. Most patients are significantly
improved after 3 sessions, but seldom clear completely.
Centrofacial and distal portion of the extremities respond less.
We offer general anesthesia primarily using propofol in an
operating room set up in our dermatology unit, and local anesthesia, with topical lidocaine under occlusion (with strict observance for dose/ weight), ibuprofen, codeine, and or midazolam.
Recent studies suggest the use of topical angiogenesis
inhibitors such as imiquimod and rapamycin may counteract
angiogenesis in the post PDl phase.1 A corrective make-up
session is offered at the hospital for certain recalcitrant cases.
Various combination therapies are being proposed for more
resistant PWs, including intense pulsed light, photodynamic
therapy, the 800 diode laser, 2 and most promising is the 755
alexandrite laser.3
treatment of hemangioma with PDl is limited to residual
telangiectasia, or actively ulcerating hemangioma with a clean
granulation base. Although studies suggest its utility in early
superficial hemangioma( it can leave hyper or hypopigmentation 4, 14% respectively) 4, simple observance or topical timolol are best in our experience, and no treatment prevents the
deeper component form appearing. the 1064nm nd-YAG laser
has been used primarily in europe for hemangioma and vascular malformations.
spider angioma usually clear after a single treatment, and only
small pyogenic granuloma <3 mm are amenable to 1–3 treatments with the PDl (Differential diagnosis spitz nevus and
amelanotic melanoma). Hypertrophic scars that are still erythematous respond well to 1–3 treatments. early bright red
angiofibroma in tuberous sclerosus respond well to PDl.
We treat warts primarily with cryotherapy, keratolytics, 5-fluorouracil , bleomycin, immunotherapy, and imiquimod, but the
PDl can be useful with total clearance varying from 48-75%
average,5,6 although the PDl is painful as high fluencies must
be used. studies have also demonstrated use of the PDl
in mollusca, however we prefer cantharone, curettage, and
imiquimod.

and silicone dressings with minimal recurrence.7 in tuberous

well. non-resectable lymphangioma with a superficial component improve at least temporarily. the CO2 laser is rarely used
now for warts, due to significant post-operative pain, scarring,
and potential recurrence.

Non-invasive Body Contouring: What’s the skinny on fat in 2011?
JAsOn K RiVeRs, MD
Vancouver
north Americans boast the
dubious distinction of being
one of the most overweight
people in the world. indeed,
23% of adult Canadians are
considered obese based on
a body mass index (BMi) of
greater than 30, while a further 36% are considered overweight (BMi 25 -29.9). this
is a growing problem and represents a target market for
several companies that have
expanded into this arena.
the pursuit for non-invasive modalities to reduce body fat is
not a new ideology. indeed, in the 1960’s mechanized belt driven devices existed to help jiggle away body fat. similar devices
were on display at the annual meeting of the American society
of Dermatologic surgery in 2010.
in Canada there are several devices currently Health Protection
Branch approved for non-invasive body contouring. some
of the more recent of these include focused ultrasound
(ultrashape Contour 1), high intensity focused ultrasound,
HiFu (liposonix), cryolipolysis (Zeltiq) and most recently
low level laser at 635 nm (Zerona). Although there have been
scientific publications to support the use of each of these
devices, the current evidence is that clinical responses can be
quite variable. in this author’s opinion, these devices need to be
used in conjunction with diet and exercise to maximize the
improvement. Approximately 80-85% of patients will be satisfied with the treatment. Why some patients do not respond is
unclear at this time.
Patient selection is critical to optimize the results. those who
have a BMi of less than 25 would be considered ideal candidates if they have small pockets of residual subcutaneous fat
around the central abdominal region or flanks (saddlebags).
the subcutaneous fat should be loose and easily pinched
between the fingers. Mesenteric fat is not appropriate for treatment as the devices will not penetrate to this level.
One of the main problems in substantiating the benefits of these
devices lies in the fact that it is very difficult to accurately
measure changes in waist circumference ( a common end point
used in clinical trials). For example, significant differences can
be obtained on the same day depending on whether the patient
has voided or emptied their bowels prior to measurements, if
the measuring tape is not held at the exact location with the
same tension, and if the patient alters their standing posture.
Photographic documentation is difficult to duplicate between
sessions – even with a dedicated system. subtle changes in posture and distance from the camera can create an illusion of a
clinical response. Perhaps the best way to determine efficacy is
to have the patient retain a pair of pants that they can wear
before and after the treatment ( weeks to months later). it is
important that the article of clothing not be washed during this
time frame.
ultrashape incorporates a 0.2 MHz low intensity fixed depth
focused ultrasound delivered through a transducer to create
non-thermal disruption of subcutaneous fat. three treatments at
2 week intervals is the general recommendation. the reported
reduction in waist circumference ranges from a remarkable 6.0
cm to a more modest 3.5 cm as presented in more recent studies. However in one report, no response to treatment was seen
in 53 Asian patients. At present the parent company is totally
revamping their device so as to incorporate radiofrequency,
vacuum assist and a transducer that can focus the ultrasound at
different levels within the subcutaneous tissue.
the liposonix system utilizes a 2 MHz high intensity variable
depth and variable fluence focused ultrasound to produce thermal coagulation of the targeted subcutaneous adipose tissue, at
the predicted locations and depths without damage to surrounding tissue including the skin and fascia. At present one
treatment session is recommended, and on average, patients
can lose 2.0 cm off their waist circumference as measured 8 to
12 weeks post treatment.
Cryolipolysis is based on the principle of cold or “popsicle”
panniculitis. the Zeltiq treatment device requires no technicians to deliver the treatment but a dedicated room is needed
for the session, each of which requires 1 to 2 hours of time. the
target area is identified and suction applied between two chilling plates that lower the skin temperature to close to freezing.
like the other treatments mentioned thus far, clinical improvement occurs over two or three months. in clinical trials a 20%
sustained reduction in fat as measured by diagnostic ultrasound
and clinical improvement has been observed. Multiple treatments with the cryolipolysis device apparently can cause a
cumulative effect.
the most recent addition to this stable is photobiomodulation
by means of a low energy 635 nm diode laser by Zerona.
Patients expose their front and back treatment area to the laser
for 20 minutes per side. treatments occur every 48 hours for a
total of six treatments. Of note, patients need to abstain from
alcohol, exercise 30 minutes a day, and to drink 2 litres of water
daily. significant combined loss (as measured over several
body sites) has been reported in the astounding range of 17.5
cm. it has been speculated that the laser creates the formation
of transitory pores in the adipose cell membranes followed by
the collapse of these cells. Critics have suggested that the science behind this data may be flawed and further follow up
(beyond two weeks) is mandatory in order to confirm whether
or not this is a transient event perhaps related to the high
volume of water intake (which has an effect on leptin).
Although adverse events from these devices are uncommon,
they may happen. in Asian patients, it has been reported that
skin ulceration can develop over bony prominences after treatment with low frequency focused ultrasound. HiFu treatment
often causes pain during therapy, while temporary bruising,

treatment of hypertrichosis with the laser is generally not recommended until after the age of 18 years, due to the likelihood
of recurrence.
308-nm excimer laser
Vitiligo
Alopecia Areata
Psoriasis
the 308-nm excimer laser can repigment at least 50% of depigmented patches, particularly of the face, neck and trunk.8
improvement can be achieved by adding topical calcineurin
inhibitors.9 Recently the eximer laser was also shown to be
effective in alopecia areata, used twice a week for a period
of 12 weeks inducing hair regrowth in 60% which was sustained in the majority.10 the 308-nm excimer laser had induced
significant improvement in psoriasis in 60% of patients after
an average of 17 sessions in a study that included some
children.11
in summary, the laser is a useful therapeutic tool in pediatric
dermatology, and we use it primarily in the treatment of vascular lesions, scars including keloids, epidermal nevi and resistant verrucae. nevus of Ota can be removed dramatically by a
Q-switched laser. the excimer laser holds promise for select
limited areas of vitiligo, alopecia areata, and psoriasis.

edema, and prolonged tenderness (the latter measured in
weeks) can develop after this procedure. Cryolipolysis may
induce discomfort during treatment, followed by numbness,
bruising and soreness. severe pain developing during treatment
and lasting for several weeks thereafter has been reported. in at
least one case, cryolipolysis resulted in a significant panniculitis that required the administration of systemic steroids.
in summary, fat busting without cutting is the new frontier
and the foie gras of those seeking midriff reduction. However,
the science of non-invasive body contouring is still in its
infancy. therefore, both patients and physicians alike should
be aware of the limitations inherent with this evolving field
before embarking on the journey to find the perfect abdominal
six pack.

Laser Complications
there are many potential laser complications. eye injuries are particularly serious and, like needle stick
injuries, everyone knows they need
to be careful but accidents still happen. the correct goggles for each
laser need to be well marked, so that
students or less experienced employees don’t think they can carry goggles from room to room. Busy physicians who already wear glasses, and
Anne CuRtis, MD,
perhaps have a syris light on as well,
toronto
have been known to forget to put on
laser goggles. lasers which can be set to different wavelengths
require particular attention, if you might have to change goggles in the middle of a procedure. Family members in the room
need an explanation for why they mustn’t take off their goggles
during a procedure. Patient safety must be protected, particularly with longer wavelength lasers which penetrate more
deeply. the laser must be angled away from the eye as even eye
shields only protect the front of the eye. Avoid treating within
the orbital rim, especially with the longer wavelength lasers.
Reflecting surfaces in the room must be avoided, since goggles
are designed to protect from sidelong exposure to the laser
beam, not from a beam pointed straight at you.
laser burns occur when the fluence is too high for one of multiple reasons. tanned patients are more likely to burn.
sometimes a patient has been treated several times before, and
as the fluence is progressively increased, eventually the burn
threshold is crossed. Patients may have been more careful with
cooling initially, and then done less cooling with a later treatment because they had had no problem before. For lasers where
the pulse duration can be adjusted, remember that shortening
the pulse duration constitutes making the treatment more
aggressive.
Post-inflammatory hyperpigmentation is very unwelcome
when a procedure is being done for cosmetic improvement.
Darker skinned patients, and patients with melasma are particularly prone to this. With fractional lasers it is more often the
density (treatment level) rather than the fluence that causes
problems. With intense pulsed light, sometimes a melasma
patient is encouraged by the first couple of treatments when
they see improvement, then discouraged when they seem to
plateau. it is dangerous to increase the fluence too much at this
stage, as the resulting post-inflammatory hyperpigmentation
can leave the patient darker than they started, though the extra
pigment may resolve with time and with bleaching creams. sun
avoidance for 3 to 4 weeks after laser treatments is particularly
critical. Most patients aren’t sufficiently conscientious with
sunscreens to expect that they can carry on with a lot of outdoor
activity and rely on the sunscreen to protect them. if they don’t
want to avoid sun exposure their treatment can be scheduled at
a less sunny time of year.
12
Post-inflammatory hypopigmentation was particularly a
problem with resurfacing lasers, but also occurs after burns.
Fortunately the burn related ones often repigment eventually.
Patients with actinic bronzing treated with intense pulsed light
may get streaks of hypopigmentation, which are in fact areas
that have now returned to the base level of pigmentation (as
seen on the ventral forearm) but which don’t match the bronzed
skin. this is a patient selection issue- some patients are not
suitable for treatment. Vitiligo can be triggered by laser treatments, and of course can appear on its own in new areas
so you can’t be certain if the laser was really responsible.
Any prospective patient with vitiligo needs to clearly understand this.
laser hair removal is known to carry a risk of paradoxical stimulation of hair growth. this is more common in Mediterranean
and east indian skin types. Frequently the hair appears at the
margins of the treated areas, and it is thought that fluences too
low to destroy follicles are the ones that can stimulate them.
the treatment is more laser at higher fluence.
A less common but very difficult to manage complication of
Q switched laser treatments is the appearance of blue grey
marks in patients who have previously received systemic gold
treatments. it is wise to specifically ask all patients who will be
treated with a Q switched laser if they ever received gold in
their life. You can put it on the information sheet for patients
and the consent form, but the patient may skim over that. the
marks may lighten with more Q switched laser treatment, but
you tend to see a widening circle where you are clearing the
center but continuing to produce new blue discoloration at the
edges. A related and more common phenomenon is a colour
change in cosmetic tattoos from red, pink or flesh coloured to
black if the original tattoo pigment contained iron. Again, theoretically you may be able to clear the black with multiple
more Q switched laser treatments, but many physicians prefer
not to use laser if they will then have black to remove. A test
spot can be done to see if the tattoo changes colour, but the
patient needs to have the whole situation explained in advance
as the black dot may have to be removed surgically.
there is a possibility of reactivation of the herpes simplex virus
any time treatments are done around the mouth. Viral prophylaxis is often recommended, especially for resurfacing procedures, usually starting the day before the procedure and carrying on for at least a few days after, depending on the anticipated healing time. Bacterial and yeast infections are also possible
in healing wounds, and the physician wants to maintain a high
index of suspicion, and treat at the first sign of a problem.
Knowledge of laser complications, how to avoid them and how
to treat them, is part of doing laser treatments. in the “Buyer
Beware” world of lasers operated in non-medical facilities,
your expertise in this area is one of the things that makes
patients value treatments provided by a dermatologist.
Lasers – to Fractionate … or not to Fractionate
traditional ablative CO2 laser
facial resurfacing was the gold
standard for many years in
wrinkle eradication but led
to a high percentage of complications such as prolonged healing, erythema and delayed,
permanent whitening. in 2004,
two decades after the original
concept of selective photothermolysis was developed by Drs
Anderson and Parish, “fractional photothermolysis,” the
MARK luPin, MD,
concept of treating microscopVictoria
ic fractions of the skin was presented. the first fractionated laser developed on this premise
was the Fraxel laser. in Canada, the Fraxel laser was approved
in 2005. As the first physician with this laser in Canada and
with prior experience in traditional fully ablative CO2 laser
resurfacing, it has been interesting to understand and watch the
evolution of fractionated devices.
the fractionated concept refers to a pixelated effect of multiple
small ablative and/or coagulative zones (i.e. microthermal
zones – MtZs). the theory is that there should be more rapid
skin healing and hence enhanced safety and lesser downtime. A
simplistic notion of skin healing is to consider that re-epithelialization comes from two stem cell populations: epidermal
stem cells and adnexal stem cells. Of these populations, the
adnexal stem cells are most important and we know that
because we have not been able to perform complete ablative
resurfacing off of the face where there is greater inter-adnexal
distance.
The Promise of fractionated lasers was perhaps to supplant the
need for heavy CO2 resurfacing and to allow speedier recoveries and with ability to treat off of the face. While it is true that
assertive CO2 resurfacing is of a bygone era, fractionated lasers
so far have not been able to erase wrinkles to the same extent –
so in this respect, we perhaps miss our old CO2 lasers.
However, wrinkle eradication is no longer the mantra – wrinkle
softening is more reasonable – but this requires managing
patients’ expectations as newer systems are actually less effective at wrinkle management.
Horizontal vs Vertical: Fractionated lasers initially reoriented
treatments from a complete horizontal skin approach to vertical
columns – like aerating your lawn rather than stripping and
reseeding. traditional CO2 laser resurfacing created its effect
through a combination of ablation and coagulation to depths of
approx. 100 and 300 microns respectively. in contrast, the
Fraxel laser coagulates to depths of up to 1500 microns.
initially, it was thought that deeper might be better which would
favour the vertical approach. However, fractionated ablative
lasers such as sciton’s erbium Profractional and fractionated
CO2 lasers like Fraxel re:pair or Deep FX have generally been
less effective on wrinkle removal when compared to fully ablative lasers. Where deeper is better is in treatment of scars.
Ablative vs Non-ablative: the first fractionated lasers were
non-ablative such as the Fraxel laser and Palomar’s lux 1540.
these were shortly followed by fractionated ablative lasers in
part because it was found that the non-ablative lasers were not
very effective for rhytides. Although the move to fractionated
ablative lasers shortened overall healing time compared to traditional fully ablative resurfacing, the initial healing period paradoxically looked worse than traditional CO2 resurfacing
because of greater swelling and sanguineous crust as a result of
insufficient coagulation.
Direct vs Indirect Effects: As with superficial erbium peels,
where treating the epidermis alone causes indirect dermal
remodeling without heating (an indirect biologic vertical
effect), there is also an indirect horizontal effect with fractionated resurfacing, whereby a true side benefit is often noted in
the overall appearance of the skin when only treating a fraction.
Energy and Density: there is an ever increasing number of
systems marketed both for fractionated ablative and non-ablative treatments. it should be kept in mind that they are not
equal. there is a difference in the ratio of ablation and coagulation of the various CO2 lasers, differences in the spot sizes
and differences in how deep they are able to treat. For example,
the Deka smartXide DOt laser is an excellent laser but is primarily a superficial fractionated CO2 laser whereas the Fraxel
re:pair and ultrapulse Deep FX are able to treat more deeply.
Spot size: i define fractionated laser treatments with spot sizes
less than 250 microns as “microfractionated,” and those with
spot sizes greater than 250 microns as “macrofractionated,” as
the larger spot sizes are easily visible to the naked eye. some
systems have fixed spot sizes and some have variable spot
sizes. the range is 135-600 microns depending on the system.
the choice of spot size depends naturally on what you are treating. For flat epidermal lesions such as lentigines and actinic keratoses, larger spot sizes and superficial depths would be ideal.
To Roll or to Stamp: the two principal methods for application of fractionated laser light to the skin are to use a stamp type
device (where the laser beam is “split” into an array of smaller
beams or the light is scanned) or to employ a rolling applicator
where a linear scanner is employed (e.g. Fraxel). Where this
becomes especially relevant is with ablative systems using high
energy and high density settings; the room for error is low and
a rolling scanner system would theoretically be better as it
should provide more even coverage. An analogy is to consider
the effect of painting a wall – if you want it to look smooth and
even, would you use a sponge … or a roller?
Shallow vs Deep: As regards the face, consider that there is
variation in the natural thickness of the epidermis and dermis
according to the region. As a rough guide, the epidermal thickness for the eyelid is approx. 50 microns compared to the face
which is approx. 100 microns. the dermal thickness for the
eyelid is approx. 300 microns versus the remainder of the face
of about 600 microns. And the upper lip, where there is
often the greatest concentration of rhytides, appears to have the
greatest thickness and will tend to need more assertive
13
treatments. shallow depths can be achieved either with systems
with shallow wavelengths such as the 1927 thulium fibre laser
on the Fraxel DuAl or with use of lower energy settings.
separate full face treatment sessions is also a consideration.
Patients’ tolerances for downtime will often dictate the best
treatment path for each individual.
Is Deeper Better? the short answer, it seems, is generally
“no.” the exception, as i have noted, is when treating deep
scars. Histologically, rhytides are scars and can be both flexible
and non-flexible which relates to how we choose to treat.
So What?
let’s consider a few common conditions and as far as fractionated devices are concerned, what we would choose as the most
effective tool:
Conditions that have benefitted the most: While we have yet
to hit the homerun, fractionated lasers have helped enormously
in treatment of melasma and scars. they have opened up a new
world of non-facial treatments such as actinically damaged
areas of the neck, chest, arms and hands.
Limitations: As with any treatment, it is important to remember that fractionated lasers are but one tool and should not be
expected to “fix” everything. A common example, i find, is
with regard to lip treatments where restoring lost volume with
dermal fillers is often just as important if not more important
than laser resurfacing alone and where the two treatments go
hand in hand for best results.
Combination Treatments:
Following are common combination treatments that i have
found truly synergistic. they are from personal experience and
not meant as a recommendation or as a substitute for good
judgement:
Fractionated non-ablative + Q switched laser or cryotherapy lentigines
electrocautery or CO2 laser 0.2mm spot treatment +
Fractionated ablative - sebaceous hyperplasia
Fractionated non-ablative (face)+ Fractionated ablative (periorbital and perioral)
Fractionated ablative lite (low energy, low density) x 2 + dermal filler revolumization - acne scars
CO2 laser 0.2mm spot + Fractionated non-ablative - fixed deep
atrophic acne scars
Fractionated ablative + photodynamic therapy +/- cryotherapy
– actinic keratoses
Vascular laser or iPl phototherapy + Fractionated non-ablative
or ablative – traumatic or surgical scars
What not to combine?
neuromodulators such as Botox Cosmetic® work well in combination with most other cosmetic procedures but should not be
performed on the same day and in the same facial region as
fractionated lasers because of the possibility of spread of the
neuromodulator beyond its normal radius of diffusion. ideally,
neuromodulators should be performed a week or two prior to
laser treatments.
Back to the Future: the paradigm shift for laser resurfacing
of rhytides from complete ablation to fractionated non-ablative
to fractionated ablative treatments is now swinging back towards
either a series of fractionated ablative treatments, realizing that one
is not enough, or consideration for a fully ablative erbium rather
than CO2 laser treatment for better risk:benefit ratio. Mixing
and matching the technologies with combination fractionated
non-ablative and ablative for different facial regions or as

In summary, fractionated lasers have revolutionized our ability to treat conditions like scars and melasma, and liberated us
to be able to treat non-facial conditions such as Poikiloderma
of Civatte. there has been great progress towards improved
safety and reduced downtime. More work needs to be done for
conditions like disseminated superficial actinic porokeratosis
and striae as well as optimizing treatments for melasma. there
is exciting work looking at enhanced topical drug delivery in
conjunction with fractionated laser resurfacing and the fractionated concept has spilled over into other technologies such
as radiofrequency devices and high intensity ultrasound.
Fractionated lasers are here to stay and have significantly added
to our treatment palette which ultimately benefits our patients.

Our annual sun Awareness program launches
this year with sun Awareness Week from June 6th - 12th, and
it focuses on safe Fun in the sun. there is a kids safe Fun in
the sun poster competition, with Provincial and national winners to be selected in 3 categories: Ages 5 and under, 6-8, and
9-12. Please mention this to your paediatric patients and to
your own children or grandchildren. there are fantastic prizes
to be won. the poster contest entry sheet and all the details are
available on our website at www.dermatology.ca/safefuninthesun/index.html. the deadline for entries is June 13th.
there will once again be skin cancer screening events across
the country during sun Awareness Week, and we will also be
conducting a screening at Parliament Hill in the fall, once
Parliament is in session. this has been very successful in the
past. i encourage all members to participate in their local
screenings. every year we detect skin malignancies in the public participants, and help to raise public awareness. it helps the
public and Canadian Dermatology, so get out there!
in the fall we will be initiating a new Hair and nails Awareness
Program. this is to raise public awareness of disorders of the
hair and nails, their impact on those who suffer from them, as
well as the fact that dermatologists are the medical experts who
help to deal with them. there will be web-based content available on the CDA website free of charge, a hair and nail
brochure for CDA members to distribute to their patients, as
well as media materials including statistics and facts about the
incidence and prevalence of hair and nail disorders.
We are also looking forward to launching our skin Health
Program, which will provide direction to patients on the best
ways to care for their skin. this will once again be accessible
through our website which is growing by leaps and bounds.
Please always mention dermatology.ca as the preferred site for
your patients to begin their inevitable online searches. Disease
specific information is available for them there.
there are also patient handouts for a variety of conditions
always available for your use on our web site, or you
may order materials from head office by emailing: [email protected]. Over time i hope you will all use
our website on a daily basis and keep a link on your desktop at
all times.
notre programme annuel de Prudence au soleil commence
cette année avec la semaine nationale de prudence au soleil,
qui aura lieu du 6 au 12 juin et qui aura pour thème « s’amuser
au soleil en toute sécurité ». nous organisons un concours
d'affiches pour les enfants sur le même thème. nous choisirons
des gagnants provinciaux et nationaux dans trois groupes
d’âge : 5 ans et moins, 6 à 8 ans et 9 à 12 ans. n’oubliez pas de
parler de ce concours à vos patients pédiatriques et à vos propres enfants et petits-enfants. il y a de merveilleux prix à gagner. On peut se procurer le formulaire de participation ainsi que
les détails du concours sur notre site web, à l’adresse www.

nous organiserons de nouveau des séances de dépistage du
cancer de la peau partout au pays dans le cadre de la semaine
nationale de prudence au soleil. nous procéderons également à
un dépistage sur la Colline parlementaire à l’automne, lorsque
les travaux reprendront à la Chambre des communes. Cet
événement a connu beaucoup de succès dans le passé.
J’encourage tous les membres à participer au dépistage dans
leur région. Chaque année, nous détectons des cancers de la
peau chez les participants du public et nous contribuons à
sensibiliser les gens. Ce type d’événement aide la population et
la dermatologie au Canada, alors participez !
nous présenterons à l’automne un nouveau programme de
sensibilisation aux maladies des cheveux et des ongles. Ce programme vise à sensibiliser les gens aux troubles des cheveux et
des ongles et à leurs conséquences pour les personnes atteintes,
ainsi qu’au fait que les dermatologues sont les experts médicaux qui peuvent aider les gens à faire face à ces problèmes.
nous offrirons gratuitement du contenu sur le site web de
l’ACD, un dépliant sur les cheveux et les ongles que les membres de l’ACD pourront distribuer à leurs patients, ainsi que
de la documentation à l’intention des médias, notamment des
statistiques et des faits sur l’incidence et la prévalence des
troubles des cheveux et de la peau.
nous sommes de plus impatients de lancer notre programme de
santé de la peau, qui orientera les patients sur les meilleures
façons de prendre soin de leur peau. encore une fois,

A Brief History of Dermatology in Edmonton, Alberta
Gilles J. lAuZOn, MD, Canmore
the early history of Dermatology in edmonton is exciting and
vibrant. the area’s first dermatologist, Dr Harold Orr (18891952), was an intense and colourful man who represented
dermatology honourably as President of the Canadian
Dermatological Association (1939), of the Alberta Medical
Association (1946-47) and of the Canadian Medical
Association (1952) 1. in the Army Medical Corps during World
War 1, he devised a dry heat chamber affectionately known as
the Orr Hut to rid clothing of lice and mites - thus alleviating
the misery associated with infestations at the front. Around
1920, following specialty training in london, he arrived in
edmonton to practice as the city’s first formally trained dermatologist and was appointed Director, Division of Dermatology,
university of Alberta. His dry heat chamber was modified to a
“steam box”, the use of which was extended to the hyperthermic therapy of syphilis in the 1920’s 2, during which time he
founded the Venereal Diseases Control Agency of Alberta
and practiced syphilology with abundant zeal. in 1933, so
impressed was he of the importance of mycology to medicine
and dermatology that he founded the Mycology unit of the
Alberta Provincial laboratory of Public Health (still in existence today). He was thereafter much involved in mycology
research and described in particular the striking variety of clinical zoophilic infections by Trichophyton menta-grophytes in
Alberta farmers: acute vesicular lesions on glabrous skin,
chronic scaly and sometimes vesicular lesions on feet and pustular, boggy, nodular lesions of the beard with hair infection3 .
His mycological research also impacted the classification of the
dermatophyte genus Microsporum, as accepted today.
Dr Harold Orr
Dr Paul Rentiers
in 1946, Dr Orr was joined by Dr Paul Rentiers who took over
the position of Director, Division of Dermatology, in 1952, at
the time of Dr Orr’s death. Dr Rentiers was President of the
Canadian Dermatology Association in 1966. A tireless clinician, Dr Rentiers dedicated himself to patient care in edmonton
until his retirement in 1975. He died in 2006, having lived
much of his retirement in the interior of British Columbia.
in 1954, Dr Rentiers had been joined by Dr isidore Hardin, an
Albertan who had completed his dermatology training in the
usA. He practiced a relentless daily clinical routine in
edmonton until 1987. the Faculty of Medicine at the
university of Alberta bestows a yearly award, the “Dr isidore
and Rebecca Hardin Prize in Dermatology”, to a medical
student who has shown proficiency in dermatology. Dr Hardin
died in Calgary in 2007.
Drs Jack Brown and noel Jampolsky, initiated their edmonton
practices in the 1960's and greatly enhanced the dermatologic
services available to the growing city. in 1975, upon Dr
Rentiers’ retirement, Dr Brown took over the position of
Divisional Director which he held until 1987. today, Drs
Brown and Jampolsky are retired in edmonton and Vancouver,
respectively.
the period 1970 to early 1980’s was to be a period of active
recruitment of clinical dermatologists to edmonton with the
arrivals of Drs Orest talpash, James Kulak, Janice liao,
Donald Groot, Bryson Rogers, eric schloss and Alfons Krol.
today, Dr talpash divides his retirement between edmonton,
Vancouver and saskatoon. sadly, Dr Kulak suffered an untimely death in 2006. All others from this cohort are still actively
practicing clinical dermatology.
in 1987, Dr Kowichi Jimbow was recruited from Japan to hold
an academic full-time position as the Director, Division of
Dermatology, university of Alberta. this marked the beginning
of the final maturation of the division. in 1988, as a result of Dr
Jimbow's efforts, the first three residents were admitted to the
newly accredited dermatology training program at the
university of Alberta – Drs naji tawfik, tom salopek and
Gilles lauzon. Dr Jimbow also set up and directed a large, well
supported and very active basic research laboratory investigating melanoma and melanocyte biology where many obtained
advanced graduate degrees (Msc, PhD). During Dr Jimbow's
tenure, Drs Barry lycka and Andrew lin (full-time academic)
started their clinical practices in 1990 and 1994, respectively.
Dr Jimbow returned to Japan in 1997 to Chair the Department
of Dermatology and Plastic surgery at the university of
sapporo. He was later appointed Dean of the Faculty of
Medicine at this same university. Presently Dr Jimbow is
retired but remains active in melanocytic research as a
Professor emeritus, university of sapporo, Japan.
Following Dr Jimbow’s departure, Dr Alfie Krol was appointed Director of the Division of Dermatology (1997-2001),
followed by Dr Gilles lauzon (2001-2007) and Dr tom
salopek (2007-present). Residency Program Directors have
included (sequentially) Drs Kowichi Jimbow, Gilles lauzon,
Andrew lin, Gordon searles and Jaggi Rao (present Program
Director). the year 2007 saw the arrival of Dr Alain Brassard
as a full-time academic dermatologist at the university of
Alberta.

the future of dermatology in edmonton appears bright and
dynamic with many young and enthusiastic dermatologists providing a wide range of medical, surgical and cosmetic services.
there is also much pride here in the fact that edmonton
dermatologists and graduates of the local program have
contributed competently both nationally and internationally to
dermatology in the realms of clinical practice, education,
research, administration and wide-ranging committee work.
thoughts of our local history bring to mind the fact that we
must acknowledge the contributions of our predecessors if we
are to understand and appreciate where we are today, and also
to give us clearer ideas about how to contribute to our society
in the future. to our many pioneers and early mentors named
above, we express our gratitude for preparing such fertile
grounds for local dermatology and for our own careers. For
edmonton, it has been a great privilege to be a part of the
history of Canadian dermatology and local dermatologists look
forward to a productive future within our professional dermatology community!

scholarships for Dermatology training”. it is assumed that the
residents applying will be driven by curiosity and a strong
desire to learn or to take part in a learning experience.
Activities undertaken primarily to acquire financial gains or
skills to produce income do not qualify. endorsement of the
application by a senior faculty member of a Canadian university is required.
Dr Kerri Purdy (R5, Dalhousie) completed an elective (supported by the Kalz Bursary fund) with Dr Melanie Pratt
september 8 to October 5, 2010 to acquire knowledge and
experience in contact dermatitis and patch testing. Dr Purdy
stated “in my training centre we don't have access to patch
testing beyond the north American Contact Dermatitis Group
standard series, so it was certainly eye opening to have access
and exposure to Dr Pratt's immense collection of allergens.....
i learned about proper patch testing including application and
interpretation, how to obtain a relevant occupational contact
history and also the management of allergic contact dermatitis.... Dr Pratt is a teacher and a mentor that i was fortunate to
be able to work with for the month.”
The CDF wishes to acknowledge the generous $6000 donation by the CDA to the Dr Frederick Kalz Bursary Fund in
2010.

Regulatory Issues
the dermatologic surgery regulatory environment continues to
evolve and has a significant impact on the practice of surgical
and cosmetic dermatology. Although each province has its own
unique set of rules and regulations, the recently approved
Ontario College of Physicians and surgeons Out-of-Hospital
Premises (OHP) standards illustrate the national trend that
originally started in British Columbia and Alberta. these
standards are designed to regulate out-patient procedures and
surgery settings and can be accessed via the web on:
http://www.cpso.on.ca/uploadedFiles/policies/guidelines/office
/ohp_standards.pdf
All dermatologic surgeons practicing surgical or cosmetic dermatology are advised to become familiar with these regulations
as they will likely apply not only to Ontario physicians but all
physicians in the future.

McGill Dermatology Program Director’s Update
i was appointed Program
Director in July 2010. i was
very proud to take on this
challenge as i have been
myself a dermatology resident
at McGill. i graduated in
1999, spent 4 years in solo
practice before deciding to
return to McGill as an academic focus to my practice. i
then did one year of Contact
Dermatitis fellowship under
Dr Denis sasseville’s supervilinDA MOReAu, MD,
sion
in 2004-2005. After that,
Program Director
i embarked as a full time academic staff within the Dermatology Division. During this time,
i have participated in building up the Contact Dermatitis clinic
that had already been firmly established and reputed by
Dr sasseville. i also took on the challenge of continuing
and supervising the leg ulcer clinic about 3 years ago upon
the departure of its founders’, Drs Marie st-Jacques and Alain
Brassard.
this past year, we were faced with some important challenges
as the MuHC is undergoing planning for the transition and
future development of its new location, the Glen Center. Many
specialties had hopes of being in this new megahospital with
brand new facilities and a strong research backbone; however
the budget has been so significantly reduced that many services will not be present within its new walls. At this point, it still
remains uncertain as to where our dermatology facilities would
be located in the future.
We have a very strong commitment within the McGill dermatology program and are striving to have our vision and voice
heard. We have been firmly advocating for adequate space and
ancillary personnel for full support to our dedicated staff. We
have also been advocating better amenities for our residents.
Our vision for the MuHC and our program is the establishment
and consolidation of specialty clinics as well as the development of an important research arm. We currently have an active
focus on many specialty clinics. For example, our Contact
Dermatitis clinic, run by Dr Denis sasseville and myself, has
acquired a renowned reputation throughout Quebec and cases
from the entire province are being sent to us for specific patch
tests which relate mainly to occupational causes. From our
clinical data, we have been able to publish a multitude of articles related to the discovery of new emerging allergens. Our
residents and students are also involved in many of those
publications, thereby increasing their opportunities to actively
participate in the medical literature while in training.
Our other specialty clinics at the MuHC include the lupus
clinic, conjointly supervised by Dr elisabeth O’Brien and our
rheumatology colleagues, the Cutaneous Problems in Organ
transplant Patients clinic, run by Dr Mannish Khanna, the
Melanoma clinic, run by Dr Beatrice Wang and the leg ulcer
clinic, run by me. We also have a busy phototherapy service
under the supervision of Dr Raynald Molinari. At the Jewish
General Hospital, we also have a strong surgical service supervised by Dr Khanna who is specialized in Mohs micrographic
surgery and a lymphoma clinic, conjointly run by Dr Kevin
Pehr and the hematology team.
We are in the process of establishing an active research arm
within our Dermatology Division and have established strong
laboratory links to develop more significant projects under the
supervision of our Research Coordinator, Dr Denis sasseville.
As Program Director, i am very proud of our focus on quality
teaching and patient care. We strive to abide by a very important philosophy, that of respect, care and empathy for patients,
peers, and colleagues and thereby promote a respectable, safe
and caring teaching environment.

Hello from sunny Manitoba! We
have just survived another year of
flooding.
Our Dermatology group has finally been successful at creating a
billing code for Moh’s surgery
with Manitoba Health. After a long
letter writing campaign and many
meetings over the importance of
Moh’s surgery for Manitoban
patients, Dr tarek Afifi can finally
ViCtORiA tARAsKA, start performing Moh’s surgery on
his long patient list. thanks to Drs
MD, Winnipeg
Jack toole, lorne Hurst, shane
silver and terek Afifi for their effort to bring this important
service to our province’s patients. it will be nice for those in
need not to have to travel to another province to receive Moh’s,
the standard of care needed for certain skin cancers. Dr Afifi has
set up his Moh’s surgery at the Winnipeg Clinic and is plodding
through his long list. Although, we have a code unfortunately it
was not the amount we feel is appropriate. so we will continue
to lobby for changes. Also we have yet to hear about our other
fee code negotiations with Manitoba Health and hopefully we
will hear soon.
Our sun Awareness campaigns this year included a screening
performed at the Manitoba legislative building with provincial
staff, MlAs and ministers. the screening team consisted of
Drs Marni Wiseman, tarek Afifi, Beth Collin and Rochelle Van
de Velde. A sincere thanks to the dermatologists who were able
to donate their time to this worthy cause. there were many staff
screened, 11 MlAs and Ministers included the Honourable Bill
Blaikie, Jim Rondeau, Andrew swan, and Dave Chomiak. We
had great media exposure for this event with many interviews
which helps disseminate our important information on sun
awareness and skin reviews to detect skin cancer. Our next
event will be the teddy Bear Picnic with loads of children
learning about safe sun exposure.

Clinical Tips & Pearls of Wisdom
BenJAMin BARAnKin, MD, toronto
In the American publication Skin & Aging, I have a column
called “Clinical Tips” where we publish tips and pearls related to diagnosis, treatment, practice management, and all other
facets related to the art and science of dermatology. Skin &
Aging is kind enough to allow us to republish these tips and
pearls in the CDA Bulletin since the publication is not readily
available in Canada.
Each issue of CDA Bulletin going forward will publish three
such tips and pearls. Please submit your tips and pearls to keep

relationship. Dacher Keltner, author of Born to Be Good: the
science of a Meaningful life (norton, 2009), maintains that
touching others is “our richest means of emotional expression.”
A warm touch triggers release of oxytocin, the hormone that
nurtures bonding and trust. Patients who receive a meaningful
touch from their doctor perceive that their visit lasted twice as
long as that reported by patients who receive no touch during
their visit. the implications of this are enormous for dermatologists, who touch nearly every patient they treat over the course
of a typical day in practice.

Hiring Staff
Reducing Patient Discomfort
i always look to hire someone with good people skills, someone who smiles and interacts well. An employee who is or was
an aerobics instructor makes a great nurse.
i provide my patients a squeeze/stress ball during procedures
where i am inflicting some discomfort such as BOtOX, fillers,
electrodessication etc. My patients have repeatedly commented
that this does indeed reduce discomfort, as does the soothing
music playing in the background which allows their minds to
go elsewhere. if you don’t want to set up an expensive overhead
system, a small CD player in each room works great.
– Dr. Benjamin Barankin
i do think that the doctor sets the tone in the office. the doctor
has to treat his patients and employees well or the employees
will follow suit.

Obituaries/ Nécrologies
Gordon Kerbel
ROBeRt lesteR, MD, toronto
On December 28, 2010,
Canadian dermatology lost an
esteemed colleague and for
many of us a good friend.
Gordon was born on February
8, 1936. He attended Bloor
Collegiate initially and later
Forest Hill collegiate. After
graduating from high school,
he entered university in science but never completed his
degree as he was accepted
1936-2010
into the university of toronto
medical school after two years in science. Gordon graduated
from medical school in 1959 and did his junior internship at the
toronto Western Hospital. subsequently, he spent two years at
Bellevue in new York. While there he had the opportunity to
train under a host of legends in dermatology including
Al Kopf and Rudy Baer. He then returned to toronto to complete his training at the toronto General Hospital as a resident
in the developing university of toronto dermatology training
program.
After graduation, he set up his office at Yonge and Davisville
and spent his entire career there. He felt it was a privilege to
be known and respected for being a general medical dermatologist and was devoted to the care of his patients. A little known
fact about Gordon is that he is credited to being the first dermatologist in Canada to recognize the cutaneous manifestations of AiDs.
Gordon also had a keen interest in academic dermatology and
spent many years seeing patients and teaching in the out patient
department at the toronto General Hospital as well as seeing
inpatient consultations. He loved to teach and was admired by
both students and residents.
Recognizing a gap in continuing medical education for dermatologists in Canada, he was the organizing founder of the Post
Graduate seminar in Dermatology over thirty years ago. this
meeting has become an important event on the calendar of
many Canadian and u.s. dermatologists since its inception
under Gordon’s leadership. He was also instrumental in initiating a Dermatology Journal Club.
Beyond his career in dermatology, he was active in the Medical
Alumni Association at the university of toronto, and was the
president of the Jewish Historical society of toronto.
unfortunately, as a result of complications of Juvenile Diabetes
his health declined over the latter years of his career, and he
retired ten years ago. He is survived by three loving sons,
steven, Howard and Jordan, who were always very close to
Gordon, as well as six grandchildren.
Gordon will be remembered for his wonderful dry sense of
humour and as a dependable colleague who contributed greatly to dermatology in toronto and nationally. He will be sorely
missed by all of us who had the privilege of being his friend or
working with him.

Remarkable Wine Tasting
several years ago, the Ontario liquor Board offered a package
of six Magnums of 2004 Clarendon Hills Wines from Mclaren
Vale, Australia.
i purchased and stored the wines on behalf of our Montreal
Branch of the international
Wine & Food society.
the producer / winemaker
Roman Bratasiuk, a biochemist and wine taster decided in the 1980’s to produce his
own wines. though he never
trained as a winemaker, he
was guided by his refined
palate and scientific knowledge. Mr. Bratasiuk’s objective was to bring out best and
unique qualities of each of his
vineyards. they hand-sourced
very old, special pre-phylloxera bush vines; made the wine
by hand, using only natural
processes, to express the unique
varietal of a vineyard by conveying its vintage and location.
We compared three varietals from the same producer (shiraz,
Grenache and Cabernet sauvignon) and also the difference in
vineyards for the same varietal (3 shiraz and 2 Cabernet
sauvignon).
