BACKGROUND During the last few decades, high-resolution computed tomography (HRCT) has come up as a new diagnostic modality to diagnose emphysematous and chronic bronchitis components of chronic obstructive pulmonary disease (COPD). The present study was undertaken to evaluate for various quantitative and qualitative HRCT features in patients with COPD, and to detect patients' characteristics t...
Loss of sleep causes deterioration of pulmonary function and ventilatory responsiveness in normal humans and in patients with chronic obstructive pulmonary disease. To evaluate the effects of variations in sleep quality on breathing, we studied 48 healthy elderly volunteers (mean age, 70 years). Electroencephalographically derived indices of sleep quality were correlated with spirometric perfor...
bronchial responsiveness to bronchodilator medications is usually tested to establish reversibility of airflow obstruction. among the various tests to establish bronchodilator response, fev1, fef25-75% or fef50%, and fvc are the most widely used. in a cross-sectional study, we assessed spirometric responses after administration of bronchodilator in 187 workers with obstructive pattern in spirom...
introduction adenotonsillar hypertrophy is a common disorder among children which, without proper treatment, may lead to considerable problems. although the consequences of this disorder have been studied in other articles, we decided to evaluate the changes in pulmonary function tests in these children after adenotonsillectomy, and the correlation between clinical and spirometric parameters. ...
