A. Pfau et al., TREATMENT OF RECALCITRANT VERRUCAE VULGARES WITH ND-YAG LASER HYPERTHERMIA (REGENSBURG TECHNIQUE) - PRELIMINARY-RESULTS IN 31 CASES, Journal of dermatological treatment, 6(1), 1995, pp. 39-42
The general principle in the treatment of cutaneous diseases with heat
is based on the fact that diseased tissue is more sensitive to the ef
fects of elevated temperature than normal tissue and thus is less able
to recover after heat exposure, Different kinds of energy sources hav
e been used to produce local hyperthermia, for example radiofrequency
or microwave electromagnetic energy and ultrasonic energy). We report
31 patients with recalcitrant verrucae vulgares who were treated with
Nd:YAG laser hyperthermia, Laser energy was applied up to three times
with an interval of 3 weeks, The laser output was 10 W, spot size 8 mm
and irradiation time up to 20 s which was repeated, With these settin
gs it was possible to reach a surface temperature of about 40 degrees
C for 30 s, After hyperthermia, no side-effects such as coagulation, b
listers or crusts were observed, An excellent response was achieved in
77% of the patients, but in 23% the method failed. No recurrence was
seen during a follow-up period of up to 9 months, This method could be
used in the treatment of finger, periungual and hand warts as well as
warts on other parts of the body including the plantar surfaces.
