Thoracoscopy is a new techique and it has not been widenly applied yet in Vietnam. During a period of time from 09/2003 to 08/2004, the researcher had thoracoscopied for 17 patients. Among them, 14 patients with pleural effusion (6males, 8 females, the ages from 20 to 80). The patients were bronchoscopy and pleural biopsy by Castelain needles for 2 to 3 times but not yet definitive diagnosis. Thoracoscopy biopsy has effective in histological diagnosis on 10/14 (72%) patients. Among the patients, cancer patients was 57%, tuberculars were 15%. There isn’t any complication.
Preliminary remark about the value of thoracoscopy in diagnosis and treatment recurrent

Study on clinical characteristics, X-ray and tidal volume in 48 patients (mean age: 66.7 ± 7.32) have co-morbid chronic obstructive pulmonary disease and bronchiectasis at Bach Mai Hospital from February to September 2004. Male to female ratio was 15 to 1. 89.6% patients were smoker. 73% of patients have smoked over 15 packs per year. 34 patients (70.8%) had bronchiectasis after 5 years having chronic obstructive pulmonary disease. 23 patients (47.3%) had this condition after 6 to 10 years of chronic obstructive pulmonary disease. Symptoms were breathing difficulty in 100% patients, barre form thorax in 72.9% patients, change in diaphragm form in plain X-ray in 100% patients. RV,RV/TLC increased by more than 20% SLT in 100% patients. 81.2% patients had disease at degree III, IV

Effect of hospital waste of Quang Nam Hospital on community health was studied in 315 people in studied place and 88 people in control place. People in studied place were more likely had history of dysentery syndrome than people in control place (p<0.001). The number of people with internal diseases in studied place was significantly was more than control place (p<0.001).These internal diseases were acute bronchitis (15.56%), gastrointestinal diseases (28.89%), nervous diseases (5.08%), urinary infection (4.13%) and anaemia. Skin and eye diseases were more common in people living in control place. Gynaecological diseases werethe same in two group

Health status of 263 people living in area near by Viet Tri province hospital (study group) was compared to that of 75 people in non-impacted area (control group). The result showed that weight and height of people in the study group was lower significantly than that of people in control group (45.84 +/- 6.28 and 1.53 +/- 0.07 compared with 49.18+/-7.03 and 1.56+/- 0.08, respectively). The number of people in the study group having history of dysentery symptom was higher than people in the control group (9.8% vs 15.9%). Due to impacts of environmental pollution, water and air pollution, the rate of people in study group with dermatophytosis diseases was higher clearly than people in control group. The dermatophytosis diseases included infected eczema, tinea pedis and tinea unguium

Retrospective description on 438 COPD patients showed that the disease occurs in male than in female subjects (male/female = 3.7 times), commonly in the year > 55 (85.3%). 153/210 patients (72.9%) have an obstructive ventilation disturbance. 142/210 patients (68.5%) have both Tiffeneau index and VC index decreasing and the Tiffeneau index decreased more dramatically than Gaensler index

173 patients admitted to the Respiratory Department of Bach Mai Hospital between 12/2000 to 7/2001 were underwent flexible bronchoscopy. The results showed that the rate of bronchial cancer was highest (57.8%). Among that, the rate of central bronchial cancer was 87% and the rate of periperal bronchial cancer was 13%. Lung tuberculosis was 8.1% and chronic bronchitis is 9.8%. Bronchoscopy was useful in diagnosing some other conditions such as asthma, sarcoidosis, laryngoptosis etc. Bronchoscopy combined with bronchial fluid aspiration produced high diagnostic value in bronchial tuberculosis. Rate of smokers in bronchial cancer patients was 60%. The higher level of smoking, the more likely to be suffered from lung cancer.

Background: Chronic obstructive pulmonary Disease (COPD) is a devastating lung disease with increasing prevalence, economic and social burden. Worldwide, it ranks as the fourth leading cause of death. Objectives: This study carried out to evaluate the prevalence of COPD in the population of Dong Da and Thanh Xuan districts, Ha Noi City. Methods: This was a cross-sectional epidemiological survey of a general population sample of 1334 men and women whose age was over 35 years old living in Dong Da and Thanh Xuan districts, Ha Noi,Viet Nam. Data on respiratory symptoms, diseases, and risk factors were collected. Lung function tests were performed with Spiroanalyzer ST300 - Japan. Results: The prevalence simple chronic bronchitis was 3.2%, (5.5% in men and 1.06% in women). The prevalence of COPD was 1.7% (in men was 2.8% and 0.7% in women). There was no previous diagnosis of COPD in 94.7% of cases. Subjects who suffered from COPD had mean of age of 62.9 years (min 47, max 81). 21.1% of COPD patients was of stage I stage, 57.9% of COPD patients was of stage II. 5.3% of COPD patients was of stage III, 15.7% of COPD patients was of stage IV. There was no symptom in 36.8% of cases. 78.9% COPD patients smoked, OR of 6.42 [2.01 - 16.6]. 47.3% of them smokes at least 15 packs/year.
Pulmonary Disease, Chronic Obstructive, Epidemiologic Studies

Intervew 590 medical staffs (73.1% female, 26.9% male) in 14 clinical departments and institutes of the Bach Mai Hospital by using direct WHO’s questionnaires. Rate of obtaining questionnaires was 91.4%. The smoking rate of male medical staffs was 40.7%. Over 80% of health professionals agreed with the facts concerning the knowledge about harmful effects of active and negative smoking, control measures on publicity, distribution and smoking in enclosed public places. Nevertheless, there were some health professionals disagreed with the fact that negative smoking associated with infant death (18.5%), maternal smoking during pregnancy increased the risk of sudden infant death syndrome (16.3%), health professionals who smoke are less likely to advise people to stop smoking (15.5%), the price of tobacco products should be increased sharply (6.8%), there should be a complete ban on the advertising of tobacco products (5.7%).

Pleural effusion was studied on 548 patients (322 males and 226 females aged 17-80 years old) at Bach Mai hospital in the period of 1996-2000. The incidence was higher in male than in female subjects. The elderly of < 60 year -old -age group accounted for 73% of cases. Tuberculosis was the most usual cause. Common symptoms were lung pain, cough, diphneoa, fever and the syndroma of “3 decreases”. The mean duration of treatment was 18.9 – 26.3 days, 17.5% of patients were fully recovered, 64.2% partly recovered and 16.1% none.
Pleural Effusion ; Therapeutics ; Epidemiology

66 patients with pleural cancers (40 males, 26 females) were treated at Bach Mai hospital from 1996 to 2000. Pleural cancer was rare and concentrating at the age group > 40, more common in male than in female. 70% of pleural cancer patient had got a history of chronical pleural inflammation. The common symptoms were chest pain, cough, dyspnoea, syndrome of “3 reduces”. Among these 66 patients, some could get secondary pleural cancer caused the metastasis and invasion from other organs. None case was consistent with previous diagnosis from lower health care service level.
