Abstract
4103 cases suspected of mycoses were analysed as to sex, age and site of disease and 3891 were proved cases. This group formed 50% of total mycoses or 13·93% of all dermatoses recorded in the Government General Hospital, Madras, during the period of study. There were 66·26% adult ♂, 27·6% adult ♀ and 6·14% were below 13 years. Dermatophytoses were found in 73·5%; the other common diseases were tinea versicolor (17·68%) and candidiasis (12·43%). Multiple sites of involvement or more than 1 disease in the same individual were mostly observed. The incidence of piedra (0·1%) and deep mycoses (0·156%) was verly low. Mycetoma was the common disease (5/6) in deep mycoses. In dermatophytoses, tinea corporis (49·71%) and tinea cruris (47·85%) commonest; tinea axillaris (3·42%), tinea capitis (1·72%) and tinea barbae (1·29%) were less common. The incidence of tinea manuum, tinea pedis and tinea unguium was similar (4·97%–6·38%). High temperature and humidity were related to the higher incidence of tinea corporis, tinea cruris and tinea versicolor. Mainly children suffered from tinea capitis. All other mycoses were commonly found in adults between 2nd and 3rd decades. In all mycoses but candidiasis, ♂ predominated. Cutaneous candidiasis was mainly a problem of housewives. Among the dermatophytes Trichophyton violaceum was predominant (33·7%) followed by T. rubrum (32·6%). Trichophyton schoenleinii and M. gypseum were rarely isolated. From mycetoma, Madurella mycetomii, Nocardia braziliensis, N. asteroides and Actinomadura spp. were isolated. Demonstration of Cryptococcus laurentii in 1 case is reported in this area for the first time. Durant 12 mois 4103 cas ont été analysés, l'étude portant sur le sexe l'âge et la localisation de la maladie; 3891 de ces cas sont des mycoses. Ce groupe représente 50% de toutes les mycoses ou encore 13,93% de toutes les dermatophyties observées à l'Hôpital Général de Madras durant le cours de cette étude. 66,26% de ces cas sont de sexe masculin (au dessus de 13 ans), 27,6% de sexe féminin (au dessus de 13 ans), et 6,14% correspondent à des enfants en desous de 13 ans (sexe non précisé). Les dermatophyties représentent 73,5% des cas, les autres mycoses étant Pityriasis versicolor (17,68%) et candidoses (12,43%). Plusieurs foyers, ou plusieurs maladies sont fréquemment observées chez le même sujet. Le pourcentage des Piedra et des mycoses profondes est très bas (0,156%). Les mycétomes correspondent aux 5/6ème des mycoses profondes. En ce qui concerne les dermatophyties, les “Tinea corporis” (49,71%) et “Tinea cruris” (47,85%) sont les formes majeures; “Tinea axillaris” (3,42%), “Tinea capitis” (1,72%) “Tinea barbae” (1,29%), Trinea manum, Tinea pedis et Tinea unguium (ces trois dernières variant entre 4,97% et 6,38%) sont les formes mineures. Le pourcentage plus élevé de “Tinea corporis” “Tinea cruris” et Pityriasis versicolor correspond à une température élevée et une forte humidité. Les enfants sont principalement atteints de teigne du cuir chevelu. Les autres mycoses sont fréquemment trouvées chez des adultes ayant entre 20 et 40 ans. Dans toutes les mycoses, sauf les candidoses, les hommes sont plus fréquemment atteints, les candidoses affectant principalement les ménagères. Parmi les dermatophytes, Trichophyton violaceum est le champignon dominant (33,7%) suivi par T. rubrum (32,6%). T. schoenleinii et Microsporum gypseum ont été rarement trouvés. Les agents de mycétomes sont Madurella mycetomi, Nocardia brasiliensis, N. asteroides et Actinomadura spp. Un cas de cryptococcose à Cryptococcus laurentii est observé pour la première fois.This publication has 21 references indexed in Scilit:
