that present at our Laser Rehabilitation Clinics on a daily basis.
The various categories of cervical spine pathologies, are reviewed
on the basis of age, gender distribution, number of treatments and
overall improvement percentages.
Results: Of the 101 patients included in this study, 49%
presented with degenerative osteoarthritis, 22% with repetitive
stress injuries, 18% with sports injuries and 12% with trauma. On
average 10 treatments of 30–45 minutes in duration were
administered for the individual patient, resulting in a significant
improvement rate averaging 94.5%.
Conclusion: Laser therapy confers benefit at both the cellular
and systemic levels, activating a variety of mechanisms
including DNA synthesis, improved microcirculation and both an
analgesic and anti-inflammatory effect. With a combination of
red and infrared LED’s and laser diodes as a light source
treatment was effective for an extensive variety of cervical spine
problems.

INNOVATIVE METHOD TO IMPROVE EFFICACY
AND TOLERABILITY OF PDT TREATMENTS
Carl Thornfeldt, CT Derm
Fruitland, ID
Background: To produce a photodynamic therapy (PDT)
regimen with improved efficacy and patient tolerability while
allowing faster administration time. This regimen consists of:
(1) Microdermabrasion.
(2) Infrared LED at 830 nm for 20 minutes to inhibit neurogenic
inflammation and stimulate deep dermal collagen, elastin and
glycosaminoglycan synthesis.
(3) 540 nm green light laser.
(4) 570 nm yellow light laser.
(5) 628 nm red LED for 20 minutes.
Study: Ten Caucasian panelists participated in an open label
unblinded clinical trial comparing results to baseline with two
PDT treatments each 4–8 weeks apart. Efficacy was graded four
weeks after second treatment. Post-op care required applying a
gel mask containing meadowfoam extract to provide DHA and
fatty acids for acetylcholine synthesis and anti-inflammatory
effect. Home care consisted of applying a barrier repairing cream
that is twice as effective as 100% petrolatum in repairing barrier
function every 2–4 hours while awake for the next 4 days. All
panelists stayed indoors for 24 hours after the treatment.
Tolerability was subjectively assessed by panelists retrospectively
comparing pain, tenderness, itching and soreness to previous
chemical peels and red and/or blue light LED-activated PDT
treatments. Fine lines, shallow wrinkles, sallowness and
roughness were measured on a 5-point scale by a board certified
dermatologist 4 weeks after the second treatment. Panelists
rated visible improvements and treatment symptoms on a 4-point
scale.
Results: All 10 panelists experienced at least a 1 point
improvement (20%) in all parameters. Six patients experienced 3
point improvement (60%) in all parameters. Subjectively all
patients reported good to marked (50–75%) improvement. All
patients stated the test regimen was markedly (75%) more
tolerable.
Conclusion: This unique regimen utilizes longer wavelength
light to maximally activate the smaller aminolevulinic acid peaks,
but not blue light peaks, yet is more effective and better tolerated
due to deeper penetration.
A PROSPECTIVE SPLIT-FACE DOUBLE-BLIND
RANDOMIZED PLACEBO-CONTROLLED TRIAL
TO ASSESS THE EFFICACY OF LIGHT-EMITTING
DIODE POSTFRACTIONAL ABLATIVE LASER FOR
SKIN REJUVENATION

Background: Light-emitting diodes (LEDs) are considered to be
effective to stimulate fibroblast activity and hasten wound
healing. We investigated the clinical efficacy of LED phototherapy
on wound healing and for improvement of discomfort
postfractional ablative laser.
Objective: To determine whether LED treatment immediately
after fractional laser skin resurfacing affects the severity and
duration of postoperative pain, erythema and wound healing.
Study: Twenty patients received treatment with a LED array
(Multiwaves, Industra, Brazil) to randomly selected facial halves
immediately after full-face fractional laser skin resurfacing with
2,940 nm erbium laser (Etherea, Industra, Brazil) and 1 week
after the laser treatment. The LED treatments were daily
alternating wavelengths of 635 nm (red) with 940 nm (infrared)
with fluences of 19.78 J/cm 2 or 11 mW/cm 2 and 9 J/cm 2 or 5 mW/
cm 2 respectively, 20 minutes of light exposure. All laser
procedures were performed by a single operator. Clinical
improvement was evaluated by participants and two blinded
physicians by observing the comparative photographs. The rate of
re-epithelialization, duration of pain, erythema, and presence of
complications were recorded immediately after the procedure and
1 hour, 24 hour, 2, 3, 4, 5, 7, 30 days post-treatment.
Results: The LED-treated facial halves were less painful in half
of the patients after the first LED session. The average time to reepithelialization
was 3 days in the LED-treated facial halves and 4
days in the LED untreated facial halves.
Conclusion: We believe that the LED after fractional ablative
laser skin resurfacing will greatly enhance the natural wound
healing process, and more quickly return the patient to a
pretreatment level of activity.

Background: The aim of this study was to evaluate in a private
practice the effectiveness of a single treatment with the PinPointe
FootLaser for onychomycosis.
Study: One hundred and ninety-seven patients (321 great toes)
from three private practices with clinical evidence of fungal nails
received a single treatment of either one-pass or two-passes of the
laser energy over all ten toe nails. Pre-treatment and follow-up
post-treatment photographs of the hallux were digitized and
computer-analysed to evaluate safety and determine efficacy and
the change in percent clear nail out to 12 months.
Results: The 2-pass treatment showed a greater treatment effect
than the 1-pass treatment (11.2% vs. 4.4% increase in clear nail at
6-months, respectively). Efficacy, percent of patients who showed
