Background/aim: Management of atopic dermatitis (AD) in children is still challenging. The aim of this study was to evaluate the efficacy and safety profile of cyclosporine-A (CsA) treatment in children with severe and recalcitrant AD. Materials and methods: Medical records of 43 children followed between January 2010 and December 2015 and treated with systemic CsA were evaluated retrospectively. Treatment efficacy was assessed according to the physician's global assessment (PGA) score. According to the treatment response, patients were grouped as nonresponder, moderate responder, or good responder. Effects of the variables on treatment response were evaluated by analysis of variance (ANOVA). The safety profile of CsA was assessed by clinical and laboratory findings at each visit. Results: The median initial dose of CsA was 3 mg/kg daily, ranging between 2.5 and 5 mg/kg daily. The mean duration of CsA therapy was 4.9 ± 4.24 months. Seventeen patients (39.5%) achieved good response in a treatment period of 3 to 14 months. After discontinuation of CsA, of the 17 patients, relapse was observed in 4 (23.5%). Moderate response was observed in 12 (27.9%) patients; however, 14 (32.6) patients did not respond to the treatment. Five patients reported mild side effects. Conclusion: Low-dose CsA seems to be an effective and safe treatment option for severe and recalcitrant AD in children.

Background: Kaposi’s sarcoma (KS) is a multifocal angioproliferative tumor involving primarily the skin. Objective: The aim of this study was to describe the clinical, demographic, histopathological characteristics, treatment modalities, and outcome of 91 KS patients, and compare them with other contemporary research. Methods: Medical records of 91 KS patients followed between January 2005 and September 2017 were evaluated retrospectively. Results: Most of our patients were male (male-to-female ratio was 4.05). The median age at diagnosis was 69 years (range, 6–93 years). The duration of the lesions varied between 3 and 25 years. The lower extremities were the most commonly involved area (51.6%). Of the 91 patients, classic type KS was seen in 75 patients. Radiotherapy was used successfully in approximately half of our patients. Recurrence was observed in approximately one third of the patients. All KS patients in this study except 1 were classic KS. Conclusion: The clinical and demographic characteristics of our patients were compatible with the previous literature suggesting that KS is a tumor that tends to be limited to the skin. Close follow-up of patients is important to monitor for recurrence. This is the largest report from Turkey to date.
