RESUMEN
Onychomycosis is a common nail infection caused by dermatophytes, yeast or other non-dermatophyte molds and have been known to be associated with significant physical and psychological morbidity. This study was performed to determine the prevalence and the etiologic agents of onychomycosis in patients attending RIMS, Imphal, Manipur for a period of two years (January 2010 to December 2012). Nail samples of 347 clinically suspected cases of onycomycosis attending dermatology OPD RIMS, Manipur were collected and were subjected to potassium hydroxide (KOH) mounts for direct microscopy and fungal culture on Sabouraud’s dextrose agar (SDA). The male female ratio of the participants was 1:1.81 (165 male and 302 female). Out of 467, 399 (85.44.%) were positive by culture and KOH mount. Young adults in the age group of 21-30 years were commonly affected. In female patients finger nail infection was more common than toe nail infection. Both toe and finger nails involvement were noticed in nine patients of which two were male and seven were female. The most frequently isolated fungus was dermatophytes, in 107 (40.38%) patients followed by Aspergillus spp in 101 (38.11%) and Candida spp in 17 (6.4%). This study demonstrated that dermatophytes, as well as moulds especially Aspergillus spp are commonly isolated from onychomycosis patients in our region.
