Prevalence of dermatophytes and other fungal agents isolated from clinical samples.

The common cause of skin infections are dermatophytes and opportunistic fungi. Aim of this study was to isolate and identify the fungal agents from clinical samples from patients with different mycoses. Clinical samples from 165 patients were subjected to potassium hydroxide (KOH) examination and culture isolation; causative agents were identified macroscopically and microscopically. All the 165 specimens were KOH positive and 110/165 (66.7%) samples were culture positive. Of these, highest isolation rate was obtained in opportunistic mycoses such as candidiasis (29/29, 100%). Dermatophytes were isolated in 53/80 (66.3%) specimens and Trichophyton rubrum was the commonest isolate in skin samples (17/24) among the patients suffering from dermatophytosis. Phaeoannellomyces wernecki was isolated in a patient suffering from tinea nigra. The study signifies the importance of mycological examination in the diagnosis of various mycoses for their effective management.

Clinical and mycological features of dermatophytosis in renal transplant recipients.

Dermatophytosis was detected in 42% of 100 renal transplant recipients screened, of whom 17% had the infection for more than 1 year. Tinea cruris and tinea corporis were the common clinical types observed. Tinea unguium presented as proximal subungual white onychomycosis (PSWO) in 3% of patients. The lesions in the majority were non-inflammatory, scaly and without central clearance. The commonest isolate was Trichophyton rubrum.

Unusual observations in the histology of Pityriasis versicolor.

Histological studies were carried out on 25 patients with various morphological types of pityriasis vesicolor. In addition to the usual features, acanthosis nigricans-like picture in papular lesions, dilated blood vessels in erythematous lesions were observed. In sections stained with Periodic acid Schiff's stain (PAS) absence of granular layer in areas of close approximation of filaments to the stratum malpighii and presence of only mycelia in the vicinity of acrosyringium were found unusual, interesting and are new findings to our knowledge.

Scenario of chronic dermatophytosis: an Indian study.

Chronic dermatophytosis was observed in 2276 (10.02%) of 22,692 patients with dermatophytosis during a period of 5.5 years. Males were affected at least 3 times more frequently than females. The age group most commonly affected was between 20 and 40 years of age. Females were affected more between the ages of 30 to 40 years. Tinea cruris and tinea corporis were the most common clinical types and tinea pedis was the least common type observed. The most frequent isolate was Trichophyton rubrum followed by T. mentagrophytes and T. violaceum. Ichthyosis vulgaris was the most common cutaneous association whereas atopy and diabetes mellitus were the most common systemic associations.

Rhinocerebral zygomycosis.

An unusual case of rhinocerebral zygomycosis with its clinical and histopathological features are presented. A good response was observed with oral itraconazole at a dose of 200 mg day-1 for a period of 3 months. To our knowledge, it is the first case report of this infection, involving the maxillary sinus, eye and the brain, from Madras, Tamilnadu, India.

Entomophthoromycosis in India--a 4-year study.

Ten cases of entomophthoromycosis encountered in a period of 4 years in Tamilnadu are reported. Basidiobolomycosis accounted for eight cases and was seen predominantly in children. Two cases of conidiobolomycosis were seen in elderly patients. Potassium iodide was the drug of choice in the treatment of entomophthoromycosis. All our patients, except one, responded with complete resolution of their lesions.
