Randomized Controlled Trial Comparative Study Clinical TrialAn open, randomized, comparative study of oral finasteride and 5% topical minoxidil in male androgenetic alopecia.
Androgenetic alopecia (AGA) is undoubtedly the most common form of hair loss in males. It is a condition which may cause cosmetic and psychosocial problems in androgen-dependent cases. In this open, randomized and comparative study we evaluated the efficacy of oral finasteride and 5% topical minoxidil treatment for 12 months in 65 male patients with mild to severe AGA. ⋯ In this comparative study of systemic finasteride and topical minoxidil, it was concluded that both drugs were effective and safe in the treatment of mild to severe AGA, although oral finasteride treatment was more effective (p < 0.05). Adverse events were not considered important either, and these side effects disappeared as soon as the treatment was stopped.

Case ReportsDermoscopy for the in vivo detection of sarcoptes scabiei.
We report the case of an 80-year-old patient who had intense pruritus which did not respond to a 3-month treatment with topical corticosteroids. On dermoscopy examination of the excoriations, we found the typical dermoscopic aspect of the scabies mite at a distance. Dermoscopy allows identifying a triangular structure which corresponds to the anterior section of the mite including the mouth part and the 2 pairs of front legs. ⋯ Traditional diagnostic methods for scabies failed in this case because the mites were at a distance from the burrows. This was due to the fact that the reaction to the mite was less pronounced and the diagnosis is frequently missed. Dermoscopy is a useful tool for the diagnosis of scabies either as a diagnostic test or to guide the traditional diagnostic tests.

Case ReportsLangerhans cell histiocytosis and juvenile xanthogranuloma. Two case reports.
Histiocytoses represent a large, puzzling group of diseases which may involve the skin and other organs. At present, juvenile xanthogranuloma is the disorder most often confused with Langerhans cell histiocytosis. A complex overlap exists between juvenile xanthogranuloma and Langerhans cell histiocytosis, with lesions showing clinical and/or pathological features of both disorders. ⋯ A possible explanation for the link between Langerhans cell histiocytosis and juvenile xanthogranuloma regards the lineage development and the relationships of histiocytes. We suggest that chemotherapy can modify the production of cytokines by influencing the conversion or 'maturation' of pathological cells into macrophages or xanthomatous cells and fusing them to form multinucleated giant Touton cells. In our opinion, the modification of the cutaneous lesions during chemotherapy in Langerhans cell histiocytosis patients, as observed in our cases, could be a favorable prognostic factor.
