Background: Pulmonary tuberculosis is a contagious bacterial infection that mainly involves the lungs, but may spread to other organs. Most people who develop symptoms of a tuberculosis infection first became infected in the past. However, in some cases, the disease may become active within weeks after the primary infection. Objective: To evaluate the diagnosis and treatment of pulmonary tuberculosis. Subjects and method: A retrospective study included 196 patients with pulmonary tuberculosis hospitalized in Department of Respiratory of Bach Mai Hospital in 2 years (2002 - 2003). Patients\ufffd?information of medical records was collected. Results and conclusions: 60.7% of patients were male and 39.3% were female. Tuberculous pleurisy was 59%, parenchymal lung tuberculosis 36%, and the others 5%. Clinical signs and symptoms included chest pain 67.9%, dyspnea 61.2%, cough 72.9% (nonproductive cough: 42.3%; productive cough: 30.6%), fever 61.2%. Dull to flat percussion, decreased to absent breath sound and fremitus 65.3% (89% tuberculous pleurisy). 27.6% of patients had positive AFB evident (smear, bronchial lavage fluid).

Background: Chronic obstructive pulmonary disease (COPD) remains a major public health problem. It is the fourth leading cause of chronic morbidity and mortality in the United States, and is projected to rank fifth in 2020 in burden of disease caused worldwide. Objective: To research the epidemiology of COPD in the population of Bac Giang city and finding out the risk factors of COPD. Subjects and method: Cross-sectional survey of general population sample of 2,104 men and women with the age \ufffd?0 years in 30 wards of 11 communes of Bac Giang city. Data on respiratory symptoms, diseases, and risk factors were collected. Lung function tests were performed with Spiroanalyzer snoo, Japan. Results and conclusions: The incidence of COPD was 2.3%; in men 3.0% and in women 1.7%. The incidence of simple chronic bronchitis was 6.4%. People who smoked had higher rate of COPD than the others (OR = 2.8). The incidence of smoking in COPD was 55.9%.
