Abstract | Full Text

A mycological study was undertaken in 250 cases of superficial mycotic infections, which included 210 cases of dermatophytosis, 18 cases of cutaneous candidiasis and 22 cases of tinea versicolor. The scrapings from all the cases were subjected to direct microscopic examination in 10% KOH solution and culture was done in case of candidiasis and dermatophytosis. Out of 250 cases direct microscopy was positive (KOH +ve) in 88 cases of dermatophytosis, 11 cases of candidiasis and all cases of tinea versicolor. Culture for dermatophytes and candida species in SDA medium were positive in 76 and 9 cases respectively. The diagnostic sensitivity, specificity, positive predictive value, negative predictive value and the overall efficiency of the direct microscopy in the diagnosis of superficial mycotic infections were calculated to be 89.41%, 83.90%, 76.76%, 93.02% and 85.96% respectively.
