A study was performed on 82 cases, among which, 50% with fast heart rhythm disorders at Quang An Hospital. Results: The most common risk factors included: exhausted or moved activities. Fast heart rhythm disorders were more common in patients with hypertension and heart valvular disease. Common symptoms included: headache, dyspnea. More severe symptoms: unconsciousness, convulsion, enuresis, systolic blood pressures < 90 mmHg.

CT-2002 air filtering mouth mask Vietnam producted was studied on electronic microscope concerning the structure, the convenience and the efficacy of dust filtering. Results showed that its efficacy reached 85-87% in an air flow of 30 liters/minute but in the flow of 95 liter/minute, the efficacy reduced to 44-46%. The evaluation of efficacy was performed similarly to American and Japanese NIOSH method

The study was performed on 727 currently working and retied officials in Thai Binh province to evaluate reality of hypertension. Results: the overall percentage of hypertension was 51% and tended to increase gradually by age- groups: < 60 years of age accounted for 8.8%; 60-70 years of age 14.7%; over 70 years of age 27.5%. The rate of hypertension in males was more than females. Hypertension level 1 accounted for 25.45%, level II 15.4% and level III 10.8%. The rate of hypertensive patients with left ventricular hypertrophy was 21%, coronary insufficiency 18.59% and heart rhythm disorder 3.5%. The rate of coronary insufficiency, left ventricular hypertrophy and heart rhythm disorder in hypertension level I group were 10.8%, 4.86%, 1.6%, respectively, lower than hypertension level II group (37.8%, 47.2%, 6.8%, respectively)

A prospective study on 65 patients (55 males – 86.9%, 9 females -14.1%) from 17-24 years of age in Intensive Care Unit, Viet Duc hospital from September 2001 to October 2003. Results as followed: Multi-traumatic (27) and severe traumatic brain injury patients (30), especially patients with shock, had high risk of pneumonia related to mechanical respiratory. Bacteria caused pneumonia mainly were Gram-negative aerobe bacillus (82.9%) in which Pneumobacillus was 40.6%, and Acinobacter was 20.3%. Pneumobacillus was quite sensitive to classical ß–lactam antibiotic group. aminoglycoside bacteria resisted 25% to amikacine, and 89% to gentamycine. Acinetobacter resisted 100% to cephalosporin 3rd and 4th generation and also resisted 41.75% to amikacine. However, it was still sensitive relatively to semi-synthetic penicillin and sensitive 100% to Imipenem.

A study was carried out on 60 patients with cirrhosis at Central Military Hospital 108 between Jan 2003 and Jan 2005. The patients were divided into 2 groups corresponding to clinical and paraclinical data. Group I included 30 patient treated by ligation of esophageal varices and group II treated by Imdur. Results: The rate of bleeding and mortality after treating by ligation of esophageal varices in group I were lower than these in group II. The mortality in both groups related to bleeding. For these patients, preventive ligation of esophageal varices had effectiveness in bleeding prevention and reduced mortality risk in comparison with the treatment by Imdur .

Studying the reality of management of medical information in 7 poor communes of Nam Dong mountain district, Thua Thien – Hue. Results showed that: commune people’s committees and district medical centers had been supervised and directed but not regularly, medical information management was not yet put into monthly workplan of local authority. Medical activities have been written almost in books, tables, statistical reports at commune medical stations, but the writing was inadequate as required. The equipment for management of medical information at medical stations were deficient. The system of medical workers in hamlets had worked not effectively.

71 patients with severe burns, who had had various organ dysfunction were divided randomly into 2 groups: one underwent continuous veno-venous hemofiltration (CVVH), and the other was control group. Results showed a significant decrease of plasma level of cytokine, including IL2, IL6, IL8 and TNF after CVVH (p<0.01). In addition, mortality rate of CVVH group accounted for 38.71%, considerably lower than those of the control group

Using white Swiss mouse at 3-4 weeks of age for injection of Japanese Encephalitis (JE) virus. Every 8 lots of the mouse had been infected with Nakayama and Beijing-1 strains by injection of 0.03ml into their brains, then followed up within 3 days. The paralysed mice were collected at the 69th hour of the beginning and at the 120th hour of the end. The interval between collection time was every 3 hours. In this study, the rate of mice with paralysis due to Beijing-1 strain was higher than those due to Nakayama strain (94.99% and 92.97%, respectively). The authors suggested that use of Beijing-1 strain to produce JE vaccine is more effective than Nakayama strain.

In the year period of 1998-2002, in the Hospital N07 in Hai Duong province and the Hospital Buu Dien in HaNoi. 117 patients (99 females and 18 males, aged 17-69) who were clinically diagnosed as thyroid nucleous, goiter were undergone a fine needle puncture biopsy. Results showed a consistency between clinical diagnosis and ultrasound in 92.9% of solid form, 93.1% liquid form and in mixt form, the consistency rate was lower 55.5%. Between clinical diagnosis and ultrasound, there was a consistency in the determination of 76% of the number of goiters, and the consistency rate was higher between these 2 diagnostic methods, 81/85 in solid form and 25/27 in liquid form, while in mixt form the technique of fine needle aspiration puncture notified more cases than ultrasound 11 versus 5
