title: [Onychomycosis by common non-dermatophyte moulds].
abstract: Between 1990 and 2000, The Medical Mycology Laboratory at University of Antioquia (Medellín, Colombia), attended 4621 patients, with nail dystrophies. We used the direct test and culture of nail samples for diagnostic purposes. This report includes 310 patients, 7% (310/4621), with positive cultures for the same non-dermathophyte fungi, in five or more places of inoculation. From the 310 positive cultures, 284 (92%) were positive in direct test. No characteristic morphology for any of the genera could be detected. Until 1989 we had an average of 9 cases per year and between 1990 and 2000 we found 28 cases per year (an increase of 211%). The implicated genera were: Fusarium 50%, Nattrassia 31%, Aspergillus and Dendrophoma 7% each, Penicillium and Scopulariopsis contributed with 2% each, and Acremonium was found in less of 1% of cases. The general prevalence of onychomycosis due to non-dermatophytic fungi was about 12,4% between 1990-2000. This report describes the main epidemiological characteristics found, comparing them with results from other authors, and defines the basic profile of affected patients: adults (31-40 years old) who use occlusive shoes (trainers) and practice sport, which predispose to hyperhydrosis and consequently to onychomycosis. The course of the disease takes in average 30 months in both sexes. The percentage of onychomycosis found was 62% for women and 38% for men.
