Improved repigmentation of generalized vitiligo in skin types IV-VI has been reported in clinical response to combined therapy with apremilast and narrowband (NB)-UVB; however, tissue responses to combined therapy versus NB-UVB monotherapy have not been elucidated. We compared the change from baseline in cellular and molecular markers in vitiligo skin after combined therapy versus NB-UVB monotherapy. We assessed lesional and nonlesional skin samples from enrolled subjects and evaluated for immune infiltrates, inflammatory, and melanogenesis-related markers which were compared across different treatment groups. Combined therapy resulted in significant reduction of CD8

BACKGROUND: The current mainstay treatment of perimenstrual acne consists of systemic hormonal therapies, which can be problematic due to their side effects, stigma, or pill burden. Topical treatments are often used as well; however, data on their efficacy in treating this type of hormonal acne are limited. OBJECTIVE: We sought to evaluate the efficacy and tolerability of clindamycin phosphate and benzoyl peroxide 1.2%/3.75% combination gel in treating perimenstrual acne in adult women. METHODS: The single-group interventional pilot study was performed on 22 adult female subjects with perimenstrual acne. The subjects applied the investigational drug daily and were assessed every 14 days for a total of 99 days. Treatment success was evaluated by the investigators using the acne physician global assessment (PGA) scoring system. Drug tolerability assessment was based on the subject-reported adverse events, as well as physician-evaluated erythema, scaling, and dryness. RESULTS: The study demonstrated a significant improvement in PGA score and lesion count, as well as patient-reported outcomes. The medication was well-tolerated in all subjects. LIMITATIONS: Limited sample size; lack of concurrent comparison group. CONCLUSION: Clindamycin phosphate and benzoyl peroxide 1.2%/3.75% combination gel presents an important topical option for perimenstrual acne.

Background Psoriasis of the intertriginous, anogenital, and facial regions remains a therapeutic challenge, with current algorithms lacking a topical agent that exhibits both high efficacy and minimal side effects. Objective To assess the safety and efficacy of crisaborole 2% ointment—a nonsteroidal phosphodiesterase 4 inhibitor—in the treatment of intertriginous, anogenital, and facial psoriasis. Methods A double-blind, randomized, vehicle-controlled trial was conducted in 21 participants. Participants were randomized 2:1 to receive 4 weeks of twice-daily treatment with either crisaborole 2% ointment (n = 14) or vehicle ointment (n = 7), followed by 4 weeks of open-label treatment with crisaborole 2% ointment. Disease severity was measured by using the Target Lesion Severity Scale (TLSS). Results After 4 weeks, participants in the crisaborole group demonstrated 66% improvement compared with 9% in the vehicle group (P = .0011). Participants in the crisaborole group continued to experience improvement through the open-label phase, demonstrating 81% lesional improvement by week 8, with 71% of these participants achieving clinical clearance. There were no adverse events. Limitations The study was limited to a single tertiary care center and small sample size. Conclusion Treatment with crisaborole 2% ointment was well-tolerated and led to clinical improvement in participants with intertriginous, anogenital, or facial psoriasis.

To evaluate the efficacy of sequential therapy of cryotherapy and sinecatechins 15% ointment BID versus cryotherapy alone in treatment of external genital warts (EGW).Forty-two subjects with at least two EGW lesions underwent cryotherapy to all lesions. One week following cryotherapy, subjects were randomized 1:1 to receive either no additional treatment or treatment with sinecatechins 15% ointment BID up to 16 weeks or until complete clearance. The total number of visible baseline and new EGW were recorded at each visit. Subjects were followed for a total of 65 weeks post-treatment.There was a significant reduction in mean number of lesions from baseline after 16 weeks of treatment in the cryotherapy-sinecatechins ointment group compared to cryotherapy alone (-5.0 lesions vs -2.1 lesions respectively, P=0.07).Cryotherapy plus sinecatechins 15% ointment BID resulted in a significant improvement in the reduction of EGW compared to cryotherapy alone.

Background: Staphylococcus aureus has been implicated in the pathogenesis of adult hand/foot dermatitis. Objective: The authors hypothesized that retapamulin 1% ointment and clobetasol propionate 0.05% foam would decrease disease severity in subjects with hand/foot dermatitis and provide a higher clearance of Staphylococcus aureus colonization, when compared to vehicle (placebo) ointment and clobetasol propionate 0.05% foam. Methods: Adult subjects with moderate to very severe hand/foot dermatitis had twice-daily topical application of clobetasol propionate 0.05% foam to hands/feet for 14 days and were randomized to apply either retapamulin 1% ointment or vehicle ointment twice daily to hands/feet and nares for five days. Results: Seventy-three percent of subjects in the retapamulin/clobetasol group were clear/almost clear at Day 15 compared to 47 percent of subjects in the vehicle/clobetasol group (p-value of 0.04). The percentage of subjects who had both negative skin and nares cultures and were clear/almost clear was also statistically significant in favor of the retapamulin/clobetasol group at Day 15 (p-value of 0.05). Limitations: Sample size, study population. Conclusion: At Day 15, retapamulin 1% ointment with clobetasol propionate 0.05% foam was more efficacious than vehicle ointment and clobetasol propionate 0.05% foam for disease improvement and Staphylococcus aureus clearance in adult subjects with hand/foot dermatitis.

Burning and/or stinging is one of the most common concerns expressed by patients using topical therapies for treatment of dermatologic disorders. Topical lactic acid preparations often are used to treat dry scaly skin. In this study, we compared the level of burning/stinging reported by participants with application of lactic acid cream 10% containing strontium versus ammonium lactate lotion 12% and cetearyl alcohol lotion. The mean rating of burning/stinging reported for lactic acid cream 10% with strontium and cetearyl alcohol lotion was lower than ammonium lactate lotion 12% (P.0001). Based on the study results, lactic acid cream 10% with strontium causes less burning/stinging than ammonium lactate lotion 12%.
