Dear Editor,
Dermatophytoses are the infections of keratinised tissues such as the epidermis, hair and nails, caused by a group of closely related filamentous fungi known as dermatophytes.[1] It is common in tropics and may reach epidemic proportions in area with high rate of humidity, over population and poor hygienic conditions. The present study was undertaken with a view to find out the clinical pattern of dermatophytosis and species prevalent in this part of the country.
A total of 102 consecutive clinically diagnosed and untreated dermatophytoses cases attending Dermatology out patient department of BLDEA's Shri B. M. Patil Medical College, Bijapur, constituted the material for the study. Pertinent epidemiological and clinical details were carefully recorded. Skin scrapings, nail clippings and infected hair were collected and subjected to mycological study both by direct microscopy in 10% KOH solution and culture on Sabouraud dextrose agar medium with chloramphenicol (0.05 mg/mL) and cycloheximide (0.5 mg/mL). Fungal species were identified on the basis of cultural characteristics, pigment production, microscopic examination in lactophenol cotton blue preparation, hair penetration test and slide culture, whenever necessary.
Fungal elements could be seen in KOH preparation in 76 cases and culture for fungus was positive in 64 cases. These 64 culture positive cases were analysed. Most common clinical pattern was of tinea corporis with cruris, followed by tinea cruris, tinea capitis,tinea corporis, tinea faciae and tinea unguium. Trichyphyton rubrum (28, 43.7%) was the most frequent isolate, followed by T.mentagrophytes (18, 28.1%), Epidermo-phyton floccosum (5, 7.8%) and Microsporum audouinii (4, 6.2%). The correlation between the species isolated and the clinical pattern is given in the [Table - 1].
Dermatophytosis was common in the age group of 21 - 30 years affecting males more than females. The higher incidence in young males could be due to greater physical activity and increased sweating. The most common clinical pattern observed was tinea corporis with cruris followed by tinea cruris. Tinea capitis was the predominant dermatophyte infection in children. Similar finding was recorded by previous workers.[5] Quite interestingly all the three genera of dermotophytes, that is Trichophyton, Epidermophyton and Microsporum have been isolated as the causative agent in our study. T. rubrum was found to be the commonest etiological agent (43.7%) which is in conformity with other reports.[2],[3],[4],[5]
The present study shows no significant difference in distribution of aetiological agents in north Karnataka as compared to other parts of India.
