OBJECTIVE To report on the proportions of restrictive, obstructive and combined types of respiratory diseases in patients referred to respiratory units at the Korle Bu Teaching Hospital. METHOD This was a retrospective study of lung function test (LFT) data on patients who were referred from clinics both in and outside KBTH. A spirometer was used to assess various lung volume parameters. RE...

Over a period of 2 years, patients with type 2 diabetes mellitus who were attending medical OPD of Dr.B.R.Ambedkar Medical College Hospital were included in the study. They were requested to attend a m e d i c a l i n t e r v i e w, a n d u n d e r w e n t physical examination including fundoscopy. Nonsmoking diabetic patients who had no history of respiratory disease, and who gave informed con...

Pulmonary function testing is a vital part of the assessment process for thoracic surgery. However, for other types of surgery there is no evidence that spirometry is more effective than history and examination in predicting postoperative pulmonary complications in patients with known chronic lung conditions. Furthermore specific spirometric values (e.g. the FEV1) cannot be taken as prohibitive...

The paper by GARCIA-RIO et al. [1] in this issue of the European Respiratory Journal provides good reference values for an under-represented population and an opportunity to review the role of reference values in interpreting lung function tests. The interpretation of all observed data involves comparisons with one or more types of reference data. In clinical medicine, the comparisons usually i...

Static lung volume (LV) measurements have a number of clinical and research applications; however, no previous studies have provided reference values for such tests using a healthy sample of the adult Brazilian population. With this as our main purpose, we prospectively evaluated 100 non-smoking subjects (50 males and 50 females), 20 to 80 years old, randomly selected from more than 8,000 indiv...

BACKGROUND The low attenuation areas on computed tomographic (CT) scans have been reported to represent emphysematous changes of the lung. However, the regional distribution of emphysema between the inner and outer segments of the lung has not been adequately studied. In this study the regional distribution of low attenuation areas has been compared by quantitative CT analysis and the contribut...

Pulmonary function studies were performed in 25 patients with pulmonary emphysema, diagnosed by clinical, roentgenographic and functional examinations. Lung function tests included spirometry, flow-volume curve, body plethysmography and single breathholding carbon monoxide transfer test. The spirometric ratio of forced expiratory to forced inspiratory volumes for the first 0.5 second (FEV0.5 /F...
