Abstract

Background: Onychomycosis is a common problem.Obtaining accurate laboratory test results before treatment is important in clinical practice since the treatment of onychomycosis requires expensive oral antifungal therapy with potentially serious side-effects. The purpose of this study was to compare results of curettage technique of nail sampling in the diagnosis of onychomycosis from three different sites of the affected nail to establish the best location of sampling. Patients and Methods: We evaluated 194 patients suffering from distal and lateral subungual onychomycosis (DLSO) and lateral subungual onychomycosis (LSO) using curettage technique. KOH examination and fungal culture were used for detection and identification of fungal infection. Results: The culture sensitivity improves significantly as the location of the sample is more proximal. Trichophyton rubrum was by far the most common pathogen detected from all sampling sites. Conclusions: We found that the culture sensitivity improved as the location of the sample was more proximal. More types of pathogens were detected in samples taken from proximal parts of the affected nails.
