Abstract Background Repeated applications of a corticosteroid can induce epidermal atrophy. This study was performed to investigate whether the adjunctive use of tazarotene gel 0.1% might help to minimize the development of steroid-induced epidermal atrophy. Methods Each of 24 healthy volunteers received the following six treatments (applied 6 days per week for 4 weeks), which were randomized to each of six sites on their forearms: no treatment, tazarotene vehicle, tazarotene vehicle + tazarotene gel 0.1%, diflorasone diacetate 0.05% ointment, diflorasone diacetate 0.05% ointment + tazarotene vehicle, or diflorasone diacetate 0.05% ointment + tazarotene gel 0.1%. Results The mean epidermal thickness was increased by 20% (NS) and 62% (P ≤ 0.0005) after applications of tazarotene vehicle and tazarotene gel 0.1%, respectively. Application of diflorasone diacetate reduced the mean epidermal thickness by 43% (P ≤ 0.0005). Concomitant application of tazarotene gel 0.1% with diflorasone diacetate did not entirely prevent atrophy, but was shown to ameliorate 37% of the epidermal atrophy induced by diflorasone diacetate alone (P ≤ 0.003 compared with steroid monotherapy). Conclusions Tazarotene gel 0.1% significantly reduces epidermal atrophy induced by diflorasone diacetate 0.05% ointment. [ABSTRACT FROM AUTHOR]

Seventy patients with tinea cruris or tinea corporis were treated with naftifine cream 1% or vehicle once daily for 4 weeks in this double-blind, randomized study. After two weeks, the patients using naftifine had a significantly higher mycologic cure rate than the vehicle-treated patients (79% vs. 31% p<0.001), ad they showed significantly better resolution of signs and symptoms. Statistically significant differences favoring naftifine over its vehicle were found throughout the treatment period and 2 weeks posttreatment. [ABSTRACT FROM AUTHOR]
