Rapid response of distal subungual onychomycosis to 5% amorolfine nail lacquer in a 20-month-old healthy infant

Antifungal therapy for onychomycosis in children

Onychomycosis is a chronic infection of the nail unit, and its prevalence increases with age. Treatment options for children are similar to those for adults and include both oral and topical therapies. Oral agents, such as terbinafine, itraconazole, and fluconazole have been reported to have good efficacy and a low rate of side effects in children. Topical therapies, such as amorolfine and ciclopirox, can also be used as monotherapy or combined with oral agents to treat onychomycosis. Due to their thinner, faster-growing nails, children are more likely to respond to topical monotherapy than adults. There is currently insufficient data comparing emerging medical devices, such as laser therapy, with standard therapeutic options to recommend their use in children.

Diagnosis and management of nail disorders in children

The authors herein describe several nail conditions, which the general pediatrician is likely to encounter in the course of routine practice. Because pediatric nail disorders represent a limited component of a general pediatric practice, it can be challenging for practitioners to establish expertise in the diagnosis and treatment of these conditions and to recognize when reassurance is appropriate or when referral to a specialist is necessary. This article summarizes the anatomy of the normal nail unit, as well as the evaluation and management of onychomycosis, melanonychia, trachyonychia, onychomadesis, and nail pitting.
