Developmental aspects of tDCS in childhood ADHD should be considered as well.Background Until recently, there was no FDA-approved antifungal treatment for onychomycosis in children. There is evidence regarding the safety and efficacy of topical antifungal agents for pediatric onychomycosis. Objective To summarize the results of a recent study using efinaconazole 10% solution to treat onychomycosis in children and discuss the management of pediatric onychomycosis. Methods In a multicenter, open-label phase 4 study, efinaconazole 10% solution was applied once daily in children aged 6-16 years with mild to severe, culture positive, distal and lateral subungual onychomycosis. Treatment was for 48 weeks with a follow-up at week 52. Pharmacokinetics was performed in a subset of patients. Results There were 62 patients enrolled in the study. At week 52 the mycological cure rate was 65% and complete cure rate was 40%. All treatment-emergent adverse events (TEAE) were mild to moderate in severity with none resulting in study discontinuation. Efinaconazole was detected at low levels in plasma. Conclusions Efinaconazole topical solution 10% is effective and safe in treating onychomycosis in children age 6-16 years and was recently FDA-approved for this indication. The off-label use of other topical agents, tavaborole solution 5% and ciclopirox nail lacquer solution 8%, and oral agents in pediatric onychomycosis is reviewed.

Allopurinol and febuxostat are the most commonly used urate-lowering therapies with established safety and efficacy in CKD patients. The objective of the systematic review is to assess the long-term renal outcomes of allopurinol compared with febuxostat in patients with hyperuricemia and CKD or kidney transpla
