BACKGROUND Losing the sense of smell, which suggests eosinophilic rhinosinusitis, is a subjective symptom, sometimes reported in asthmatic patients taking controller medication. Upper abdominal symptoms, suggesting gastroesophageal reflux disease (GERD) or functional dyspepsia, occur also in these patients. However, the relationship between these symptoms, concomitant with asthma, and the inten...

The most popular way to define asthma based on questionnaires is to use definitions taken from cross-sectional international studies on asthma. These definitions may not, however, be optimal for future studies focusing on risk factors of asthma. The current authors, therefore, compared the performance of different operational definitions of asthma. The European Community Respiratory Health Stud...

BACKGROUND Rhinosinusitis is a common, expensive disorder with a significant impact on patients' quality of life. Chronic sinus symptoms are associated with allergic rhinitis, asthma, and nasal polyposis. Saline nasal irrigation is an adjunctive therapy for rhinosinusitis and sinus symptoms. Prior studies suggest that hypertonic saline nasal irrigation (HSNI) may be effective for symptoms assoc...

OBJECTIVES Diagnostic patterns play a role in asthma prevalence estimates and could have implications for disease management. We sought to determine the extent to which questionnaire-derived estimates of childhood asthma reflect the disease's true occurrence. MATERIALS AND METHODS Children aged 6-12 years from Katowice, Poland, were recruited from a cross-sectional survey (N = 1822) via prima...

METHODS The study included 3136 Dutch children participating in the Generation R Study, a prospective cohort study. Adjusted ORs o...

although researchers in this decade have proposed several answers concerning the association between socio-economic levels of health, still one question is not well understood: whether in school or domestic environments, low and high socio-economic status may influence asthma and respiratory symptoms on primary school students. the aim of this study was to investigate the extent to which primar...

Background: Asthma is a highly prevalent chronic respiratory disease in children. Moreover, the underlying causes of asthma exacerbation are important because they are effective in controlling and preventing asthma. The aim of this study was to evaluate the helicobacter pylori infection in controlled and uncontrolled asthmatic children compared to healthy children. Methods: This case- contro...
