Onychomycosis in João Pessoa City, Brazil.
Onychomycosis epidemiology is a combination of various factors which include, among others, clinical presentation, etiologic agents of the infection and the patient's history background. Out of a total of 672 nail samples examined, 460 (68.4%) were microscopy positive for fungi and 306 (66.5%) of these were culture positive, including Candida (82%), dermatophytes (13.4%), Trichosporon spp (3.6%) and nondermatophyte molds (1%). Onychomycosis was more frequent in females (79.7%) than in males (20.3%). These were more common in fingernails (96.1%) than in toenails (60%) and yeasts were the most isolated etiologic agents. Among the clinical presentations, paronychia (CP) (57.2%) and onycholysis (CO) (24.8%) were the most common, caused frequently by C. albicans in 52.6% and 60.5% of the cases, respectively. T. rubrum (44.4%) and Trichosporon spp (22.2%) were the most frequent species in the case of distal lateral subungual onychomycosis (DLSO). Fusarium spp was the agent responsible for 33.3% of the cases of proximal subungual onychomycosis (PSO) and for 14.3% of white superficial onychomycosis (WSO), whereas Acremonium spp was responsible for 14.3% of the cases of WSO.
