| Sumario: | 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) Tinea unguium es una micosis común en muchas partes del mundo, incluyendo Irán. La incidencia de esta micosis puede variar dependiendo del tiempo, salud y localidad geográfica. Para averiguar la etiología, epidemiología y factores de riesgo de tinea unguium, se estudiaron pacientes con uñas con posible de infección por dermatofitos entre 1996-2004. Durante este estudio, 590 pacientes (354 mujeres y 236 varones) con clínica probable de infección fúngica en las uñas de manos, pies o en ambos, fueron investigados mediante examen directo, así como por cultivos de muestras clínicas. Tinea unguium se presentó en 41 casos (7%) y, de entre los casos positivos, 18 (44% del total de casos positivos) fueron mujeres y 23 (56% del total de casos positivos) fueron varones. Diecisiete pacientes (41% del total de casos positivos) presentaban tinea unguium en uñas de las manos y 24 (59% del total de casos positivos) presentaban infección en las uñas de los pies. Desde un punto de vista etiológico, en el 65,5% (19 casos) las onicomicosis fueron causadas por dermatofitos zoofilos, en el 31% (9 casos) por antropófilos y en el 3,5% (1 caso) por geofilos. Tinea unguium no presentó diferencias significativas entre sexos. La mayor presencia se dio en pacientes entre 11-40 años de edad. En definitiva, parece que en el noroeste de Irán tinea unguium está asociada con el cuidado de animales y el contacto directo o indirecto con sus productos (lana, cuero). |
