Detection of fungi spectrum in industrial and home bakeries and determinated fungal allergy with skin prick test.

Airborne fungal pathogens such as Penicillium, Aspergillus, Cladosporium, Trichophyton, and Alternaria may cause health problems. In this research, the fungal flora at different bakeries and their potential allergenic effects on the workers were investigated. We investigated 148 workers at 17 industrial type bakeries and 62 workers at 17 home type bakeries in Afyon. Our study was performed in two different seasons and climates, between January 2004 and June 2004. Fungal flora was detected by using Petri-dish method. In the winter, Penicillium was the dominant genus, while Cladosporium was the dominant genus during the summer, in both types of bakeries. The allergenic properties of dominant culturable fungi on workers involved in the bakeries were determined with the skin-prick test. It was found that with workers in the industrial type bakeries, the most common skin test positivity was caused by Penicillium. In the other hand, the skin test positivity, performed on workers in the home type bakeries, was equally caused by Penicillium, Trichophyton and Aspergillus.

The prevalence of asthma among secondary school students in Afyon, Turkey.

Ethnic origin has been reported to affect the prevalence of atopic diseases in several studies in different parts of the world. The aim of this study was to determine the current and cumulative prevalence of asthma, allergic rhinitis, atopic dermatitis and reactivities to allergen skin prick tests (SPT) among secondary school students in Afyon, Turkey. The data of the first stage were collated through the application of the European Community Respiratory Health Survey Questionnaire on 1,400 students (1,366 were properly completed) registering at various schools in Afyon-Turkey, in the academic year 2000-2001. At the second stage, a physical examination and SPT were performed on 121 students. Of the students within the study group, 53 (3.9%) had experienced an asthma attack within the previous 12 months, 49 (3.6%) had a past history of asthma attacks and 167 (12.2%) reported wheezing attacks within the previous 12 months. The cumulative prevalence of asthma, rhinoconjunctivitis and dermatitis were found to be 7.46%, 8.10% and 3.5%, respectively. A positive SPT reaction to at least one allergen was found in 15.7% of the students. SPT positivity was 11.13% in symptomless students and 20.3% in asthmatic students. In analysis of logistic regression, a history of atopy, as determined in the questionnaire, was seen to be significantly correlated with SPT positivity. The prevalence of self-reported asthma and/or asthma-like symptoms was shown to be lower in students living in Afyon than other countries. Asthma and asthma-like symptoms were found to be significantly more prevalent among students who smoked.
