| To the Editor,|| |
Please refer to Letter to the Editor entitled "Mycological aspects of dermatomycosis in Yavatmal (Maharashtra)" by KV Ingole et al. We want to share our observations in a similar study done in our institution during the period January, 1995 to December, 1995.
From 298 clinically diagnosed cases of tinea infections, skin scrapings/nail clippings/hair specimens were examined for the presence of fungal elements by direct microscopic examination in 10% KOH solution. 195 cases (65.43%) were KOH positive and they were further subjected to culture study on Sabouraud's dextrose agar media. 140 cases (71.80%) showed culture growths of pathogenic dermatophytes.
The commonest dermatophyte isolated was Trichophyton rubrum (88 isolates, 62.86%) followed by Trichophyton mentagrophytes (50 isolates, 35.71%), Trichophyton tonsurans (1 isolate, 0.7%) and Epidermophyton floccosum (1 isolate, 0.7%).
Trichophyton rubrum was found to be the main aetiological dermatophyte species responsible for dermatophytoses in our region (62.86%), followed by Trichopyton mentagrophytes (35.71%). This is in confirmity with other published reports.
The various clinical types of tinea infections in the 140 culture positive cases were tinea cruris (42 cases, 30%), tinea unguium (33 cases, 23.57%), tinea corporis (30 cases, 21.43%), tinea buttocks (15 cases, 10.71%), tinea pedis (10 cases, 7.14%), tinea manuum (5 cases, 3.57%), tinea capitis (2 cases, 1.43%), tinea barbae (2 cases, 1.43%) and tinea faciei (1 case, 0.7%). This is also in confirmity with other published studies.
The majority of our patients (23) were active workers [farmers(7), drivers (3), labourers (5) and semiskilled workers (8)] doing strenuous physical work leading to profuse sweating. Most of our patients were wearing tight and synthetic clothes which caused more warmth and moisture of the body. These factors made the body surface suitable for the growth of dermatophytes and led to the high incidence of tinea cruris and tinea corporis cases. The high incidence of tinea unguium in our study might be due to the trauma inflicted to the nails as a result of hard physical work and habit of walking and working barefooted.
