Abstract

Onychomycosis is a nail disorder caused by dermatophytes, non-dermatophytes and yeast. A clinico mycological study was conducted among individuals working in different environmental conditions for the incidence of nail disorders. This study was aimed to screen occupational workers of both sex and different age groups and also the predisposing factors. A total of 1028 individuals were screened, amongst which 417 workers were suspected with onychomycosis. Samples from suspected individuals were subjected to KOH examination and fungi were identified on Sabourauds dextrose agar medium. Nail infections were found in 143 workers. The highest incidence was recorded among farmers and gardeners followed by washermen, hotel workers, labourers and hospital workers. The most common type of onychomycosis was distal and lateral subungual onychomycosis (57.42%) followed by total dystrophy (26.57%), Proximal subungual (12.58%) and Superficial white onychomycosis (7.69%) in the same order. Males recorded a higher number of nail infections than females. The most predominant dermatophytes isolated were Trichophyton rubrum. Among the nondermatophytes genus, Aspergillus was common. Our study revealed onychomycosis to be very common in individuals working with soil or in wet environmental conditions. In most instances creating awareness and personal hygiene could prevent the incidence of nail disorders.
