Fungal nail infections: far more than an aesthetic problem.

Onychomycosis (fungal nail infection) is common and causes considerable discomfort and pain for many otherwise health patients. However, onychomycosis is especially prevalent in some patient groups seen regularly by community nurses (e.g. the elderly and people with diabetes, human immunodeficiency virus (HIV) infection or psoriasis). This article discusses the causes and types of onychomycosis, and examines in detail the various treatments available. Both the infection and its treatment can cause several clinical problems including drug interactions, difficulties with differential diagnosis and compromise of clinical outcomes. In particular, onychomycosis can undermine foot care in people with diabetes. The role of community nurses in treating and preventing onychomycosis is discussed.
