INTRODUCTION: The term onychomycosis is used for fungal infections of the nail unit. Tinea unguium is defined as a dermatophyte nail infection. The aim of this study was to determine the epidemiological characteristics of onychomycoses.
MATERIAL AND METHODS: Ambulatory patients of the policlinic department of the Clinic of Dermatovenereology in Novi Sad were included in this study. Every patient with clinically suspected nail changes was examined. Direct microscopy of nail clippings and isolation of fungi on Sabouraud agar were performed. The results were evaluated using standard statistic methods.
RESULTS: During a one-year-period (1995-1996) 70 cases of onychomycoses were registered that is 1.07% of the total number of patients examined in this period (N = 6535). The vast majority of observed patients were females (N = 47-67.14%), and male patients were significantly less frequent (N = 23-32.86%, p < 0.01). The most frequent type was dermatophyte onychomycosis (N = 39-55.71%), and the most often isolated agent was Trichophyton mentagrophytes (N = 38-54.29%). Manual workers were most often affected (N = 18-25.71%). Most patients were in the 41-50 year age group (N = 23-32.86%). The mean age of patients was X = 47.64 years (SD = 15.39). Table 4 shows the clinical duration of different types of onychomycoses. The longest clinical course was in the group of dermatophyte onychomycosis (20 years, one case). The mean clinical duration of the whole group was 26.81 months (SD = 40.04). Table 5 shows presence of other dermatomycoses associated with onychomycoses. Tinea pedis was the most frequently observed dermatomycosis (N = 9-60.00%).
DISCUSSION: The incidence (1.07%) is something less than usual, and other findings are compatible with standard results. A lower incidence could be the result of the fact that children under 17 years are managed at the Institute of Mother and Child Health Care in Novi Sad.
CONCLUSION: This study is a contribution to epidemiological investigations of onychomycoses. This disorder, with its social and medical importance and dubious treatment results, puts onychomycoses on high level of interest in modern dermatovenereology.
