Tinea incognito due to epidermophyton floccosum

Tinea incognito is a cutaneous infection with atypical clinical characteristics. Disease is usually caused by administration of steroids. We describe a 25-year-old man who presented with local lesion in groin being treated with corticosteroid. Epidermophyton floccosum, an anthropophilic species, was identified by mycological examinations, direct and culture

Tiña corporis y tiña capitis / Tinea corporis and tinea capitis

La tiña es una infección de la piel, piel cabelluda, uñas o pelo causada por hongos dermatofíticos que invaden el estrato corneo y usan la queratina como nutriente. Existen tres géneros de dermatofitos: Trichophyton, Epidermophyton y Microspurum.

Etiology of tinea corporis in Karachi

To find out the demographic distribution and species of dermatophytes causing tinea corporis in Karachi, Pakistan. Design: Prospective study. Place And Duration: This study was conducted in the Department of Microbiology, Basic Medical Sciences Institute, Jinnah Postgraduate Medical Centre, Karachi from September 2000 to August, 2001. Subjects and Ninety-nine patients having skin infections [clinically suspected cases of tinea corporis] were examined. The skin scraping were taken from active border of the lesions and subjected to direct microscopy and culture on mycobiotic agar [Difco] for isolation of dermatophytes. Various special media were used for species identification. Tinea corporis was generally predominantly seen in adult [74.8%] than in adolescent [14%] and children [11.1%]. Out of 99 cases 53 [53.5%] were males and 46 [46.5%] were females. Tinea corporis was relatively more common in males. 48 strains were recovered out of these 29 [60.4%] strains of Trichophyton rubrum, 09 [18.7%] strains of Epidermophyton [floccosum], 08 strains of Trichophyton violaecum and two strains of Trichophyton mentagrophytes. Tinea corporis was relatively more common in males. Trichophyton rubrum was the most frequently isolated dermatophytes. Species identification is necessary to prevent spread of infection and choice of appropriate antifungal agent

effect of proteinases [Keratinases] in the pathogenesis of dermatophyte infection using scanning electron microscope

To study the inter-relationship between the stratum corneum of host and the fungal micro- organisms using scanning electron microscopy for a complete understanding of the host parasite relationship. Setting: The patients attended the outpatients of Department of Dermatology, King Abdul Aziz Hospital Makkah. The isolation and identification was carried out at the Department of Mycology University Hospital of Wales, Cardiff, U.K. Material and Skin surface biopsies were obtained from two patients suffering from tinea cruris infection. One patient was infected with Trichophyton rubrum and the other with Epidermophyton floccosum strains. The scanning electron microphotographs obtained from two patients showed a large number of villi in the infected area. The fungal hyphae were seen to be placed intercellularly as well seem to be transversing through the corneocytes in many places. From the results observed in this study it could be suggested that the secretion of proteinases from the fungal hyphae together with the mechanical force of the invading organisms in vivo might be playing part in the invasion of the organisms

study of dermatophytoses in a central hospital in Asir region, Saudi Arabia

Sick leave, lead to loss of workdays and national money. This study evaluates a general belief, that a large number of Sick Leave Notes [SLN] are issued from. Accident and Emergency Department [A/E]. We found that only 3.5% out of all patients attending A/E were issued SLN. 97% patients were issued leave for one to two days only, these patients had mild to moderate illness only, and the leave was justified. We conclude that A/E doctors do not issue large number of SLN, most of the SLN are justified
