“…This was contrasting to the research by Yadav et al, 25 T. rubrum (38.46%) was the commonest aetiological agent in majority of clinical types followed by T. mentagrophytes (33.33%), T. tonsurans (17.95%) and fungi other than Dermatophytes (10.26%) and Vineetha et al, 14 with T. rubrum was the most common species isolated in the first episode and in chronic dermatophytosis followed by T. mentagrophytes. Rare species, such as T. tonsurans and single cases of T. schoenleinii, E. floccosum and M. audouni, were isolated from chronic cases.…”

Dermatophytosis are fungal infections caused by three genera of fungi that have the unique ability to invade and multiply within keratinized tissue (hair, skin, and nails). Although dermatomycoses are globally distributed, the endemic and most prevalent species of dermatophytosis differ strikingly from one geographic locality to another. Changing trend has been noticed in last few years with dermatophytic infections presenting as chronic, treatment unresponsive and recurrent. Also various microscopic and fungal culture studies have shown shift in identification of causative fungal species in recent years. Numerous studies have been done on the occurrence of dermatophytes in various parts of our country illustrating the range and changing pattern of fungal infection as well as causative fungal species. Total number of 150 patients attending outpatient department of our hospital who were clinically diagnosed as having superficial dermatophytosis were enrolled into the study. Patients were carefully screened as per inclusion and exclusion criteria and then enrolled in the study. Samples were taken from all the patients and examined for KOH direct microscopy and sent for fungal culture on Sabouraud’s Dextrose Agar as well as on Dermtophyte Test Medium. Results were then analyzed using standard statistical methods. Out of total 150 patients, 101 were males and 49 were females. Most common age group was 21-30 years (37.3%). 58 patients (38.7%) showed positivity to KOH microscopy as well as fungal culture. Additionally 25 more samples demonstrated positivity to KOH microscopy (total 83 patients) but negativity to culture, while 9 patient samples were positive to culture but negative to direct microscopy. Predominant fungal species isolated on culture was Trichophyton mentagrophytes (50.7%) while next common species isolated was T. tonsurans (29.9%). No significant association was found between dermatophyte isolate on culture and clinical type. Trichophyton mentagrophytes and Trichophyton tonsurans were the most common species isolated among subjects with Tinea faciei, Tinea cruris and Tinea corporis. The study showed a male preponderance and T. corporis was the commonest clinical type found. Majority of patients were in the 3rd decade and came within a duration of 1 month to 6 months of getting an infection. In patients diagnosed with tinea corporis, tinea cruris, tinea pedis and tinea manuum, T. mentagrophytes was the most predominant species isolated.

“…Microsporum canis fue el principal agente etiológico aislado en la población de este estudio, lo cual contrasta con observaciones realizadas en otros. En una investigación realizada en Etiopia, en estudiantes de escuela básica primaria, el agente etiológico predominante fue Trichophyton violaceum 12 , mientras que en pacientes pediátricos de la India, T. mentagrophytes fue la especie identificada con mayor frecuencia en todos los sitios, excepto en el cuero cabelludo, donde fue más común la identificación de T. tonsurans 13 . En los últimos 10 a 20 años, T. tonsurans ha sido el microogranismo más frecuentemente aislado en los casos de tinea capitis en Norteamérica y Centroamérica, y en algunas regiones de Europa y África 14 .…”

Introducción. Las dermatofitosis son infecciones fúngicas superficiales de epitelios queratinizados. La tinea capitis es una de ellas y afecta a poblaciones escolares vulnerables. Carpinelo es un barrio del área periférica de Medellín con precarias condiciones socioeconómicas. Ante la sospecha de un brote de dermatofitosis, losafectados fueron evaluados.Objetivo. Evaluar clínica y microbiológicamente pacientes del barrio Carpinelo con sospecha de micosis cutáneas para determinar la presencia de un brote por dermatofitos.Materiales y métodos. Se llevó a cabo un estudio descriptivo, de corte longitudinal, con muestreo a conveniencia. Se hizo una búsqueda activa de casos en el Jardín Educativo Buen Comienzo de Carpinelo en niños de la institución y sus familiares. Se evaluaron clínicamente y se tomaron muestras de escamas y cabellos para exámenes directos y cultivos microbiológicos. Se analizó el perfil demográfico, clínico y micológico, con el programa estadístico SPSS™, versión 25.Resultados. Se estudiaron 57 pacientes, 47 eran menores de edad con una media de edad de seis años; se observó una proporción de hombres y mujeres de 2:1. Los pacientes con resultados positivos se diagnosticaron con tinea capitis (78,95 %), tinea faciei (15,79 %) y tinea corporis (10,52 %). El 75,43 % de los pacientes recibió tratamiento previo y de estos el 69,73 % fue con esteroides. El examen directo fue positivo en el 53,84 % y los cultivos en el 46,5 % de los casos. Los agentes aislados fueron: Microsporum canis (77,77 %), Trichophyton spp. (11,11 %), Trichophyton rubrum (5,55 %) y Malassezia spp. (5,55 %).Conclusión. Tinea capitis fue la presentación clínica más común y M. canis el dermatofito más frecuentemente aislado. Llamó la atención el uso de esteroides como primera y única opción del tratamiento empírico‚ lo cual resalta la importancia del diagnóstico microbiológico para proporcionar la terapia apropiada.

“…Family history in older studies in adults ranges from 20-48%, 16,17 but in children was as high as 90%. 18 Special populations like elderly and children have relatively lesser contact with persons outside their family hence they are more likely to be infected by a family member. Various factors at play in the Indian scenario are overcrowding, poor hygiene, sharing of clothes, towels, linen and footwear.…”

Introduction Superficial tinea infections are some of the most common dermatological conditions in the elderly. Recently, few studies done showed an abrupt increase in dermatophytic infection in adults; however, similar recent studies describing dermatophytosis in the elderly are lacking. The aims and objectives of this study were to identify the epidemiological profile of dermatophytoses among the elderly population. Materials and Methods This was a single centre, observational cross-sectional study conducted at a tertiary care Medical College Hospital in North India over 12 months including patients of dermatophytosis (KOH confirmed) aged 60 years or more. Results A total of 192 patients were enrolled, among which 68.7% were males. The extensive disease was present in 56.2%. History of topical steroid usage was present in 79.2%. The mean duration of disease was 23.8 weeks among which chronic disease was seen in 25%. Various other demographic characteristics were identified. Various risk factors for extensive disease, like gender, topical steroids use, urban residence, higher socioeconomic status, longer duration of disease, positive family history, diabetics, regular alcohol and tobacco consumption, were also noted in the present study. Conclusion The present concludes increased prevalence in women, delay in seeking treatment among them, a rising proportion of chronic and extensive dermatophytosis, rising atypical clinical presentation and higher predilection for tinea cruris and onychomycosis.
