We aimed to study the possible effects of exposure to a summer smog episode on the respiratory health of 212 school children. Furthermore, the suitability of the forced oscillation technique (FOT) to demonstrate such effects was evaluated. Acute respiratory symptoms were evaluated by questionnaire and lung function was assessed by spirometry and respiratory impedance measurements. For each chil...
BACKGROUND The diagnostic use of lung function using spirometry depends on the validity of reference equations. A multitude of spirometric prediction values have been published, but in most of these studies older age groups are underrepresented. OBJECTIVES The aim of the present study was to establish new spirometric reference values for advanced age and to compare these to recent prediction ...
BACKGROUND The 2007 Guidelines for the Diagnosis and Management of Asthma provide evidence-based recommendations to improve asthma care. Limited national-level data are available about clinician agreement and adherence to these guidelines. OBJECTIVE To assess clinician-reported adherence with specific guideline recommendations, as well as agreement with and self-efficacy to implement guidelin...
Abstract Background: Workers who exposed to cotton dust are at risk of some occupational lung diseases such as byssinosis and chronic bronchitis. In general respiratory symptoms like chronic cough, sputum and dyspnea are more common in cotton dust exposed workers. With continuous exposure, progression of disease and pulmonary dysfunction will happen. In this study, we assessed the effect of co...
background: occupational asthma (oa) is the most common occupational lung disease in developed countries. one of the causative agents is metal fume that may be encountered in steel industries. screening for the oa is mainly performed by questionnaire but in our country spirometry is used more commonly. objective: to compare the diagnostic value of the venables standardized respiratory questionn...
OBJECTIVE To explore spirometry utilization among general practitioners and identify practitioner and practice-related factors associated with spirometry utilization. DESIGN Multivariate multilevel cross-sectional analysis of a questionnaire survey. SETTING Some 61 general practices involved in a spirometry evaluation programme in the Netherlands. All practices owned a spirometer and were t...
Introduction: Among the pollutants present in the ceramic and tile industry, silica dust is particularly important, and many studies have investigated the effect of this material on the respiratory system. Many occupational exposures may result in a decrease in spirometric parameters. Materials and Methods: In the present study, totally, 120 male workers and employees of the factory, who had w...
