RESUMO
BACKGROUND/AIM: We investigated the role of body flora and chronic inflammatory infections in the etiology of allergic disorders in Turkish children. MATERIALS AND METHODS: Forty pediatric asthma patients with positive skin prick tests and 40 age-matched healthy subjects with negative skin prick tests were enrolled in this cross-sectional study. Serum H. pylori IgG, viral hepatitis serology, IL-10, and TGF-beta levels were measured. Stool and throat cultures were taken and tested for occurrence of microorganisms. RESULTS: A significantly higher percentage of nonatopic subjects tested positive for anti-H. pylori antibodies compared to atopic subjects (60% vs. 20%). Serum IL-10 levels were also significantly higher in nonatopic subjects. No significant differences in direct microscopy and culture specimens of stools were observed. Examination of throat flora showed significantly higher occurrences of Neisseria and beta-hemolytic Streptococcus in nonatopic subjects, but higher occurrences of gram-positive bacilli in atopic subjects. CONCLUSION: Higher prevalence of anti-H. pylori antibody and higher serum levels of IL-10 in nonatopic subjects suggest that chronic infection and inflammation may protect against atopic disease. Higher occurrences of Neisseria and beta-hemolytic Streptococcus in throat cultures from nonatopic subjects are novel findings that lend further support to the hygiene hypothesis.

BACKGROUND: Previous studies on school-based education programs have reported that asthmatic and nonasthmatic adolescents, teachers and school personnel do not have enough information on asthma. However, the number of education programs including adolescents without asthma is not sufficient. The aim of the present study was to determine the knowledge of school children about asthma and to investigate whether their knowledge of asthma can be increased by an education program through a booklet distributed as a handout. METHODS: This cross-sectional prospective questionnaire survey was carried out in a private school in Ankara, Turkey, between February and April 2006. 720 adolescents in grades 6, 7 and 8 were included. Knowledge about asthma was evaluated by a scoring system before and after the education offered by means of a booklet. RESULTS: The final analysis was conducted on 642 students in total. The number of right answers in 5 categories, percentage of right answers and total questionnaire score improved significantly after the education received (p < 0.001). The total questionnaire scores of the girls (p = 0.002), those students with a university graduate mother (p = 0.006) and those with a physician parent (p = 0.041) were higher than those of the other pupils. CONCLUSION: Theoretical material in the form of a booklet can be used in a school-based asthma education program in order to improve the knowledge of adolescents about asthma.

The study involved 1342 primary school students aged 7-14 years who applied to Ankara, a primary care center for general health check-up between 2006 and 2007. Forty-three students, 35 of whom had PE and 8 of whom had PC, were subjected to thorax measurement. All 43 students underwent pulmonary function tests (PFT).The prevalence rate of PC was 0.6%, and of PE, 2.6%. The thorax widths of the groups were similar (P = 0.273). The thorax circumference and depth of PE group were lower than those of the controls (P < 0.05). The probability rate of abnormality in PFT scores of PE group was statistically significantly higher than that of the controls (P = 0.022) whereas absence of normal PFT scores the difference between PC group and the controls was not statistically significant (p = 0.095). The results indicate that more than half of the individuals with pectus deformity do not have any physical complaints and do not have statistically significant differences in their PFT parameters.
