The treatments given 2~3 times week until complete clearance lesions achieved or there partial improvement without further amelioration, in spite 5 additional treatments. rate clearing monitored by estimating severity (PRSS) score pruritus score.The extent all 15 lessened during (30.1+/-3.6 vs. 2.0+/-1.6, respectively, p<0.05). overall reduction PRSS showed significant second third treatment. 12 treatment period, unchanged remaining 3 patients. mean previous duration 11.2+/-4.9 days this did not interfere successful outcome phototherapy.This shows that is useful, well-tolerated option suffering from eruptions considerable pruritus.
