Abstract
Background Onychomycosis represents the most frequently encountered nail disease, which is difficult to eradicate with drug treatment. Epidemiological studies concerning onychomycosis have been performed in many countries worldwide. Differences in the incidence of onychomycosis have been reported not only for various geographical areas, but also for different regions of the same country. Objective This survey was undertaken to determine the epidemiology of onychomycosis in the population of Crete, Greece. Methods In a prospective study, the fingernails and toenails of all new patients presenting to the outpatient Dermatology Department of the University Hospital of Crete were examined by certified dermatologists. If they appeared abnormal, nail material was obtained for mycologic examination. Results A total of 23 477 patients were examined during the study period (1992–2001). Of them, 19 556 (83.3%) participated in the investigation. Clinical abnormal nails were observed in 2098 (10.7%) patients, 36.7% males and 63.3% females. Mycologically confirmed onychomycosis was detected in 511 (24.3%). Toenail onychomycosis was found in 283 (55.4%) patients, fingernail onychomycosis in 210 (41%), and both toenail and fingernail onychomycosis in 18 (3.6%). In the toenail infections, dermatophytes were most frequently isolated (52%), followed by yeasts (24.7%) and moulds (15.5%); 7.8% of the infections were mixed. In the fingernail infections, yeasts were most often isolated (82.9%), followed by dermatophytes (10%), and moulds (1.9%); 5.2% of the infections were mixed. Conclusion Because the pattern of onychomycoses in a country is changing with time, epidemiological studies are necessary for determining the prevalence and the causative agents of the infection.Keywords
