Abstract

  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.

Abstract

 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.

Abstract

  Background & Objectives: Pools and Saunas are one of the most public areas that may cause superficial and cutaneous mycoses in humans. So investigating the fungal flora in the mineral swimming pools like Sarein area can remove or reduce the contamination or prevent the probablity of fungal infection.

  Methods: A total of 284 samples from 11 mineral swimming pools were taken of which 214 were from pools, sauna Jacuzzis, tubs and showers which were covered by sterile moquette and 70 were from water in saunas, jacuzzis, tubs and showers which were collected in sterile test tubes. All of the samples were cultured in standard method on sabouraud dextrose agar (SDA), sabouraud dextrose agar+oleic acid (S+O) and sabouraud dextrose agar+ chloramphenichol+cyclohexamide (SCC) medias, then identified macroscopically (colony morphology )and microscopically.

  Results: From 284 samples, 193 were contaminated with fungi. The most frequently isolated species in 11 pools were Aspergillus fumigatus (22/79%), Aspergillus flavus (15/54%), Aspergillus niger (15/54%) and Penicillium (14/5%) respectively. On the other hand, Ulocladium, Sepedonium, Acremonium, Pscilomyces, Stemphylium and Streptomyces with 0.51 % were the least frequently isolated species. In this study, no dermatophytes or other true dimorphic pathogenic fungi were isolated from samples.

  Conclusion: So it can be concluded that routine hygiene inspections such as disinfection of pools, personnel training and following hygienic rules were much effective in lowering the comtamination. Also mineral waters of these pools can be growth inhibitors of pathogenic and dermatophytic fungi.
