Psoriasis Treatment
4.8.1.
Clinical Background
The
mistral
psoriasis
treatment
relayes
upon
selective
photothermolysis in which emition of green and yellow light emitted by
the Psoriasis Care Handpiece coagulates the capillaries which feed
the psoriatic lesions. Mistral also emits a pulse of heat which reduces
swelling and inflammation and relieves pruritus.
Thirteen patients participated in a controlled study. Patients received
two therapy regimens in parallel; LHE treatments plus salicylic acid
20% and salicylic acid cream alone as control. Treatments were
applied two times a week spread evenly over a 4-6 week period.
In eleven patients who completed the treatment regimen, average
global PSI score for the treated sites was reduced by 65%. In contrast,
on the control sites average global PSI score was reduced by only
7.4%. Six patients (55%) had a significant improvement of 70%
reduction or above in their PSI score, ten patients (91%) had a 50% or
above reduction while only one patient had a poor response (12.5%
reduction in global PSI).
It was concluded that LHE selective photothermolysis, combined with
salicylic acid, appears to be a practical modality for the treatment of
mild to moderate psoriasis. Patients experience only mild discomfort
with no convalescence downtime.
