Background & Objectives: Tina capitis is among the most prevalent human infections induced by dermatophytes. Some dermatphytic factors are globally widespread while some others are geographically determined. A number of similar researches have been conducted in Iran however, due to the geographically diverse etiology of the disease and lack of similar research in Meshkin Shahr, the present study was conducted to determine the prevalence of tinea capitis in primary schools of this city.
Methods: In order to determine the frequency of the tinea capitis in the students of primary school in Meshkin Shahr, children in 13 schools including 2470 boys and 3012 girls were studied. For this purpose first of all the children’s scalps were observed clinically and the specimens such as hair and scale were taken from 228 pupils. The specimens were examined by direct and culture methods.
Results: Of all the subjects, 38 students (0.7%) had tinea capitis. The prevalence rate was 0.8% and 0.6% among boys and girls respectively, which was statistically significant. The high degree of disease was seen in 11 year old students (39.5%) and the main source of infection was Trichophyton violaceum.
Conclusion: Desptie a decrease in tinea capitis among children especially in primary school pupils nationwide, there is still a considerable (0.7%) rate of prevalence in Meshkin Shahr which demands attention.

Background & Objectives: In spite of extensive advances in diagnosis and treatment of cutaneous diseases, cutaneous fungal infections are still one of the important reasons to refer to dermatology centers. Incidence of dermatophytosis species is different in various regions. Recognition of these agents has important role in its treatment and eradication. The aim of this study was to determine the various species of dermatophytes in patients referring to Haft-e-Tir Hospital, Tabriz.
Methods: This descriptive-analytical study was done on 518 patients referring to Haft-e-Tir hospital from 1997 until 1998. Direct examination in their cutaneous and nail lesions was positive for dermatophytosis. All the samples from their lesions were cultured in special culture media including dextrose agar and sabouraud's dextrose agar plus chloramphenicol and cyclohexamide. The collected data were analysed by SPSS software.
Results: There were positive cultures in 70.3% of the cases. Trichophyton verrucosom was the most common agent in all of cutaneous and nail infections. Involvement was more common among the subjects under 15 as well as among males and villagers. Tinea corporis was the most common clinical form of the disease.
Conclusion: The findings indicated that zeophilic species and anthropophilic respectively are the most common dermatophytosis species in the region under study. Culture was positive only in 3/4 of the samples.

Background & Objectives: Malassizia furfur (pityrosporum ovale/orbicular) and other related species are ethologic agents of tinea versicolor and pityrosporosis in normal individuals but fungal infections due these yeasts are a major cause of mortality in immunocompromised and cancer patients. Catheter-related fungemia or foliculitis is most common mycoses in immunocompromised cases, but malassezia Spp., has been frequently implicated as the causative agent of peritonitis, septic arthritis, mastitis, and sinusitis and variety ocular infections. In this study we surveyed Pityrosporom ovale in dandruff of patients with leukemia underlying chemotherapy.
Methods: Over a one year period, 100 scale samples were obtained from 50 patients with leukemia underlying chemotherapy. All samples were stained using Metilin Blue method. In direct microscopic examination, seeing budding yeast cells with certain numbers, (bottle bacillus) on epithelial cells were reported positive sample.
Results: Pityrosporosis were dtected in %78 patient with Leukemia. Most of patients were range of 21-30 years old (27%), that suffering from increased scale.
Conclusion: Malassezia fur fur is one of more common noncandidal yeasts causing a variety of fungal infection. This organism is a lipophilic yeast that colonizes superficially in human skin and causes superficial mycoses such as tinea versicolor, rarely catheter– related sepsis, foliculitis and other systemic mycoses. Most reported cases of systemic mycoses due to this yeast have been in neonates or adults with malignancy or immunocompromised patients, who were receiving parenteral lipids via a central vascular catheter, undergo chemotherapy and BMT. As pityrosporosis were positive in over than 82% of studied patients, suggested that for prevention of serious fungal infections and mortality in immunocompromissed patients, it must be considered a suitable anti fungal protocol for these cases such as using shampoo or other drugs containing antifungal agents for treatment of patient underlying chemotherapy.
