Study on the status of worm infections and the effectiveness of deworming campains and health education based on community in 570 children from 2 to 5 years and 570 women of reproductive age in Quang Xuong district, Thanh Hoa province from July 2000 to December 2002. The results showed that: among children: the rate of ascariasis and trichuriasis infection were highly prevalent. Worm infection intensity of these species was light – moderate. The relationship between worm infection and malnutrition among children was not found at the baseline survey. The prevalence of hookworm among women reproductive age decreased clearly after the first round of treatment with albendazole 400mg, but no other parasites decreased significantly in both mother and children. There were no influences of interventions to improve anaemia status in both chidren and women reproductive age

A cross-sectional survey on KAP and local IEC activities in malaria control for the ethnic minority people of Raglay was carried out in Khanh Hoa province's Khanh Vinh district in order to produce appropriate IEC materials for this group of population. The interviews of 400 random samples from 8 villages of two communes showed that 85.93% of respondents correctly understood the causes of malaria, 94.47% seek treatment in the health center if they got ill, and 82.22% correctly knew how to prevent from malaria. IEC for malaria control was made mainly through the local mass media of loudspeakers and health workers. Posters and leaflets were found to be poor and not highly effective. It is recommended to implement IEC campaigns on the face to face basis, community meetings, and network of local health communicators.

Since 2000, the authors have been conducting technical cooperation on nosocomial infection control at Bach Mai Hospital (BMH) in Vietnam, which is the first trial in the country. The main contents include: (1) Consolidation of the bases of nosocomial infection control at BMH, which include setting up the appropriate control system and providing training for hospital staff, (2) Cooperation in the SARS outbreak, (3) Fact-finding survey on nosocomial infection, and (4) Preparation against avian influenza at hospitals. As a result of these activities, nosocomial infection control at BMH has been enhanced and the staff is providing technical guidance to other hospitals in recent years with the aim to disseminate skills and knowledge widely in Vietnam. The questionnaire survey on preparedness against SARS, including awareness among staff, training situation, infection control system in hospital, etc., showed comparatively good results in Vietnamese hospitals. The present paper summarizes the collaboration on nosocomial infection control between Vietnam and Japan.
Nosocomial infection control is considered essential to upgrade the quality of medical care. Also, constant efforts to upgrade the skills and knowledge of medical staff and to set up an efficient infection control system will be useful in dealing with the potential risk of resurgence of SARS or human influenza pandemic. Nosocomial infection control is one of the most appropriate subjects for technical cooperation at hospitals in developing countries.

Background: Standard treatment for pleural infection includes of drainage and antibiotics. Chest tube drainage often fails if the fluid is loculated by fibrinous adhesions. Intrapleural fibrinolysis may facilitate pleural drainage. Objective: To evaluate the role of Streptokinase (STK) in the treatment of empyema and exudative pleural effusions. Subjects and method: A study included 34 patients (21 patients with exudative pleural effusions, 13 patients with empyema), aged 15-77 years. All patients received intrapleural STK daily with dose of 300.0000-500.000 UI for empyema and 300.000 UI for exudative pleural effusions. Response was assessed by clinical outcome, pleural fluid drainage, chest radiography, pleural ultrasound. Results: Mean pleural fluid drainage after STK instillation was higher in all patients. Pleural fluid drainage was 640 \xb1 494 ml before STK instillation and 823 \xb1 755 ml after STK instillation for empyema; 765 \xb1 691 ml before STK instillation and 1,033 \xb1 757 ml after STK instillation for exudative pleural effusions. The success rate of clinical outcome was 100%. Only 2 patients required decortications. Fever occurred in 3 patients (8.8%) and allergy in 1 patient (3%). Conclusions: Intrapleural STK was safe and effective in the treatment of empyema and exudative pleural effusions. STK prevents pleural adhesions and reduces the risks for surgery.

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%. The three most important risk factors of COPD was the age \ufffd?0; smoking >15 pack/year and medical history of asthma.
