A STUDY ON DERMATOPHYTOSES IN A TERTIARY CARE HOSPITAL OF WEST BENGAL
Journal Title: Journal of Evolution of Medical and Dental Sciences - Year 2017, Vol 6, Issue 76
Abstract
BACKGROUND Dermatophytoses refer to superficial fungal infection of keratinized tissues- skin, hair and nail caused by keratinophilic dermatophytes. According to worldwide scientific observations, dermatophytoses are the most common of the superficial fungal infections, especially in tropics and subtropics due to high humidity. The study was performed to assess the occurrence of different clinical profile of dermatophytic infection in a tertiary care hospital of West Bengal and to identify the species of various dermatophytes. MATERIALS AND METHODS This is a descriptive study. A total of 85 clinically suspected cases of dermatophytoses, attending a tertiary care hospital in Kolkata were selected for the study. Direct microscopy in 10% potassium hydroxide (KOH) for skin and hair and 20% KOH for nail were performed. Culture was done in Sabouraud Dextrose Agar (SDA) and Sabouraud Dextrose Agar with chloramphenicol and cycloheximide (SDCCA). RESULTS Out of 85 clinically suspected cases, 79 presented with tinea cruris, 4 cases presented with onychomycosis and rest 2 cases presented with tinea capitis. Majority of the cases (67%) were reported from low income group (Below Poverty Line card holder); 67 cases were positive on direct KOH mount and 29 were culture positive. Amongst these 29 culture positive cases, in 23 cases both KOH and culture were positive (79%) and remaining 6 cases were negative on direct microscopy showed culture positivity. Trichophyton rubrum was the predominant species isolated (82%) in all clinical types followed by Trichophyton mentagrophytes (18%). CONCLUSION Culturing the fungus for identification of the species is not always possible due to low sensitivity.
