Average duration of hospital days was 12.9 days.

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
