| dc.description.abstract | Tinea unguium is a common mycosis in many part of the world including Iran. The prevalence of this mycosis varied depending on time, health level and geographical location. To stabilise the etiological, epidemiological and risk factors of tinea unguium in North-west Iran, a study of patients with suspected dermatophyte infections of their nails was carried out between 1996 and 2004. During this study 590 (354 females and 236 males) patients with clinical presentation of fungal infection in fingernails, toenails or in the both sites, were investigated using direct microscopy and culture of clinical samples. Tinea unguium was documented in 41 cases (7%) and among positive cases, 16 cases (39% total positive cases) were female and 25 cases (61% total positive cases) were male. Seventeen patients (41% total positive cases) had tinea unguium in their finger nails and 24 patients (59% total positive cases) had infection in their toe nails. According to the isolated etiologic agent, 66% (19 cases) of tinea unguium infections were caused by zoophilic drematophytes, 31% (9 cases) were caused by anthropophilic drematophytes and 3% (1 case) were caused by geophilic dermatophytes. With regard of sex, tinea unguium did not show a significant difference. The highest prevalence of tinea unguium was found in patients between 11 and 40 years of age. In conclusion the current results identified the etiological agents and epidemiological aspects of tinea unguium in North-west Iran. Tinea unguium in this region is associated with animal husbandry and direct or indirect contact with their products (wool, leather). | |
