Background:Vitiligo, a common disorder of depigmentation, is often difficult to treat. Corticosteroids are known to be effective, but with modest results. Although simvastatin has been reported to be effective for immunorelated dermatologic disorders including vitiligo, controlled trials are lacking. This study was conducted to compare the efficacy of topical betamethasone valerate 0.1% cream (as a standard method of treatment for vitiligo) versus a combination of betamethasone valerate plus oral simvastatin in the treatment of vitiligo.Materials and Methods:Eighty-eight subjects with symmetric vitiligo who had body surface involvement up to 20% were divided randomly into two groups. Group A were treated with betamethasone valerate 01% cream twice daily and Group B with betamethasone valerate 01% cream twice daily and oral simvastatin 80 mg daily for 12 weeks. Finally, 46 patients completed treatment after 12 weeks in both groups. The results were evaluated by a blind dermatologist using Vitiligo Area Scoring Index (VASI) score at baseline, 4th, 8th, and 12th week of treatment. In a similar way, subjective assessment performed by patients based on photo evaluation at the end of the study.Results:Despite a continuous reduction in VASI score in both groups, according to both physician (P = 0.13) and patient (P = 0.374) assessment oral simvastatin was not statistically more effective than conventional treatment of vitiligo.Conclusion:This study indicates that oral simvastatin is not associated with significant impacts in the treatment of vitiligo as compared to other inflammatory dermatologic conditions such as psoriasis. Indeed, other studies should be initiated regarding exact molecular and cellular effects of statins in the treatment of vitiligo.

Cutaneous leishmaniasis (CL) is endemic in many parts of the world with a high economic and health impact. Despite many treatments that have been suggested for this zoonotic infection, there is still no definite therapy for CL. Meglumine antimony compounds are considered as a standard treatment for leishmaniasis, however, these medications have a relatively high side effect profile and not always effective. Physical modalities including cryotherapy, laser, and heat therapy have also been used for this purpose. As a source of heat therapy, different methods have been used including radiofrequency, ultrasound, infrared, exothermic crystallization thermotherapy, and microwave. We reviewed all of the articles in PubMed regarding the use of heat therapy for the treatment of CL up to January 2020. According to our literature review, heat therapy using different sources showed promising results for the treatment of CL that were comparable to meglumine antimony. In addition, heat therapy has very low side effect profiles that are localized to the treatment area suggesting this method as a safe procedure for CL therapy. This study is a brief review of the literature about the effect of heat therapy on the treatment of CL. Performing randomized clinical trials to compare different methods of heat therapy and to compare it with meglumine antimony compounds is recommended.

Gracilaria algae is red macro algae which has demonstrated considerable antiinflammatory effects. Our objective was to compare the efficacy of Gracilaria algae topical cream 3% vs Clobetasol cream 0.05% in treatment of plaque-type psoriasis. Thirty adult patients with baseline modified Psoriasis Area and Severity Index (PASI) score ≤12 were randomized to receive either Clobetasol or Gracilaria algae cream on right or left-sided symmetric plaques once daily for 8 weeks and follow-up of 4 weeks. Modified PASI score, patient's satisfaction using VAS and global physician assessment score were assessed to evaluate clinical response. Thirty patients with 94 symmetrical psoriasis plaques were enrolled in this trial. The mean baseline modified PASI score of both sides was similar; however, at the end of trial, modified PASI score was reduced more on the sides treated with Gracilaria algae cream (0.80 ± 0.19% vs 0.63 ± 0.25%, P < .05). No significant difference was found regarding mean physician global assessment score between the two groups (P > .05). Patients' satisfaction was significantly higher in favor of algae cream only at week 8 of the intervention (P < .05). Gracilaria algae cream can be an effective and safe alternative of Clobetasol in the treatment of plaque type psoriasis.
