Small airway diseases are seen in many clinical conditions. The locations of small airway diseases are small bronchioles including terminal and respiratory bronchioles, and alveolar duct. The histopathologic features of bronchiolar injury have been described variously and have led to confusing and overlapping terms. The purpose of this article is to describe the clinical characteristics and histopathologic interpretation of small airway diseases. We classify the small airway diseases as primary bronchiolar diseases, and secondary bronchiolar diseases including pulmonary parenchymal diseases, and large airway diseases with prominent bronchiolar involvement. Primary bronchiolar diseases include respiratory bronchiolitis, acute bronchiolitis, constrictive bronchiolitis, follicular bronchiolitis, diffuse panbronchiolitis, mineral dust airway diseases, and a few other variants. Pulmonary parenchymal diseases with bronchiolar involvement include respiratory bronchiolitis-associated interstitial lung disease, organizing pneumonia, hypersensitivity pneumonitis, pulmonary Langerhans' cell histiocytosis, sarcoidosis and idiopathic pulmonary fibrosis. Bronchiolar changes can also be seen in large airway diseases such as chronic bronchitis, bronchiectasis, cystic fibrosis and asthma. The patterns of bronchiolar response to various injuries are relatively limited and these patterns are generally non-specific in regard to the etiology. Appropriate interpretation and diagnosis of small airway diseases depend on judicious correlation of clinical, radiologic, and histopathologic characteristics.

The typical radiographic findings of bronchiolitis obliterans organizing pneumonia (BOOP) are known to be patchy air-space consolidation that is often subpleural, and with or without ground-glass opacities. However, there are scant radiologic reports about the micronodular pattern of BOOP. We report here on a case of BOOP that manifested as diffusely scattered ill-defined centrilobular micronodules on HRCT.

The study included 64 patients with chronic cardiopulmonary disease caused by chronic bronchitis and bronchial asthma at early stage in Viet Tiep Hai Phong Hospital between 2002 and 2003. Results: Patients who are over 50 years of age accounted for 89.1%; male 87.5%; female 12.5%. Patients had disease duration more than 10 years were 84.2%. Commonest clinical symptoms were breath shortness in excise (100%), tachycardia (87.5%). Major laboratory findings: hyperleukocytosis (34.4%), increased sedimentation rate (37.5%), ECG right axis (40.6%), pulmonary P wave (100%), absence of right ventricular hypertrophy (100%). On Doppler ultrasonography: flat a wave (65.6%), pulmonary hypertension (65.6%)

Clinical examination on 87 patients with chronic bronchitis at Vinh Tien - Vinh Bao - Hai Phong in 2003. Results showed that common clinical symptoms are cough and expectorate (100%), breath shortness (88.51%), normal thoracic cavity (63.21%), rales (100%). VC and FVC reduced dramatically (65.52%), FEV1 reduced significantly (71.27%), PEF reduced remarkly (74.72%)

'Nhi tran thang' is a traditional receipt, which has been used for treatment of chronic bronchitis. Therefore, we have been studying the way and means of modifying from the traditional receipt, pharmacological effects (acute toxicity; anti-sputum, anti-tussive) of the 'Nhi tran thang' and modified receipts. According to results, we have chosen the best one of them, which will be researched to find out a suitable formula of drug

PURPOSE: To determine the utility of HRCT in the diagnosis of chronic airflow obstruction and to correlate the morphologic abnormalities revealed by this modality with functional impairment in patients with chronic air-flow obstruction. MATERIALS AND METHODS:This study involved 80 patients with chronic airflow obstruction who underwent HRCT and a pulmonary function test. Final clinical diagnosis in these patients was determined by a chest physician on the basis of clinical features, bronchoscopy, pulmonary function test, and HRCT. In order to diagnose and determine the extent of areas of decreased attenuation revealed by HRCT (the CT score), the find-ings of HRCT were retrospectively reviewed by two radiologists, who reached a consensus. Clinical and HRCT diagnoses were then compared, and the rate of agreement between them was calculated. The relation-ship between the extent of areas of decreased attenuation revealed by HRCT and by FEV1/FVC was evaluated using Correl 's account and Student 's unpaired t-test. RESULTS: The agreement rate between clinical and HRCT diagnoses was 77.5% (62/80). The rates for bronchiec-tasis (88.9%, 24/27), emphysema (93.9%, 31/33), and bronchiolitis obliterans (100%, 6/6) were considerably higher than those for chronic bronchitis and bronchial asthma. The correlation rate between CT score and FEV1/FVC was significant in bronchiectasis (p<0.05; r: -0.76) and bronchiolitis obliterans (p<0.01; r:-0.66), but not in cases involving emphysema, bronchial asthma, or chronic bronchitis (p>0.05). CONCLUSION: HRCT is valuable in the diagnosis and prediction of physiologic impairment in patients with bronchiectasis and bronchiolitis obliterans, but has limited value in those with emphysema, chronic bronchitis or asthma.
