Reversibility of airways obstruction in chronic bronchitis.
1. Airways resistance and lung volume were measured in twenty-five patients with chronic bronchitis and fifteen patients without chest disease before and after the inhalation of isoprenaline. Similar measurements were made on fourteen of these patients with chronic bronchitis and twelve other patients without chest disease before and after the intravenous injection of atropine sulphate. 2. Ther...
متن کاملClinical value of assessment of acute reversibility of airways obstruction in patients with COPD.
Editorials on a CT slice. Using 10 mm thick CT slices, the diagnostic yield from fiberoptic bronchoscopic procedures (FOB) was 60 percent for SPNs with the positive bronchus sign, and 30 percent for SPNs without this sign. Some SPNs were also scanned using 1.5 mm thick slices (thin-section CT), and the diagnostic yield of SPN without the positive bronchus sign dropped from 30 to 14 percent. Thi...
متن کاملAssessment of reversibility of airway obstruction in patients with chronic obstructive airways disease.
Spirometry before and after an inhaled beta agonist or a course of oral prednisolone is widely used to detect reversible airflow limitation in patients with chronic obstructive lung disease. How many of these patients have a response and how the response to beta agonists relates to the response to corticosteroids is not clear. In 127 outpatients (mean (SD) FEV1 0.92 (0.38) 1) who had a clinical...
متن کاملTapering analysis of airways with bronchiectasis
Bronchiectasis is the permanent dilation of airways. Patients with the disease can suffer recurrent exacerbations, reducing their quality of life. The gold standard to diagnose and monitor bronchiectasis is accomplished by inspection of chest computed tomography (CT) scans. A clinician examines the broncho-arterial ratio to determine if an airway is brochiectatic. The visual analysis assumes th...
متن کاملAirways obstruction in rheumatoid arthritis.
Owing to the report of an association between rheumatoid arthritis (RA) and obliterative bronchiolitis we have determined the prevalence of airflow obstruction in unselected patients with RA and normal chest radiographs. Spirometry was performed on 100 patients with rheumatoid arthritis and 84 control subjects matched for age, sex, and smoking habits. Patients with rheumatoid arthritis had sign...
