69 patients with hypertensive intracerebral hemorrhage (HICH) admitted within 24 hours of stroke onset. 14/69 patients (20.3%) with enlarged hematomas after the first CT was performed during 30 minutes at admission and the second within 24-36 hours of admission (33%). Multivariate analyses revealed that the following three factors were independently associated with hematoma enlargement: the time from stroke onset, prothrombin ratio, the shape of hematoma. Hematoma enlargement was an independent factor increasing the mortality rate in the HICH patients

Between November - December 2000, hemoglobin level was measured in members of 9,879 households in 7 ecological regions. Among these, 7,135 households have under 5-year children; 2,744 households have pregnant women. The results showed that the overall rate of anaemia in under 5-year children is 34.1%; this rate in under 2-year children is 50%. The average hemoglobin content is lowest in under 2-year children. Rate of anaemia varies between ecological regions. For women, rate of anaemia is highest in Southern Central Part. For under 5-year children, rate of anaemia is highest in T©y Nguyªn region. This rate is higher in rural than in urban. Other factors related to anaemia are educational level of women, parity, pregnancy and living condition.

Incidence of pregnant diabetes ranges from 1 to 14%, depending on region, race and diagnostic criteria. Studying on 196 pregnant women who were given antenatal care at Ha Noi Obstetric Gynecological Hospital provided some findings as follow: the incidence of pregnant diabetes in studied population was 3.6% when using diagnostic criteria of the National Diabetes Data Group (NDDG) 1979; the incidence of NDNG was 4.1%. The overall incidence for diabetes and GDNG was 7.65% and is was increased further by 2% when applying new diagnostic criteria of Counstan and Carpenter 1982. The incidence was increased in pregnant women who had some risk factors such as history of diabetes in family, obese (BMI was 25 or more), urinary glucose (+) and older age of pregnant woman.

In May 1999, we performed a study of evaluation of HBV infection by ELISA techniques for HBsAg, Anti-HBs and Anti- HBc in the sera. 206 medical students(2 -year grade, Faculty of Medicine, Ho Chi Minh City) were enrolled with the following results: 112(54%) students without infection (HbsAg (-), Anti- HBs (+), 16(8%) carriers with 14(6%) having HbsAg (+) and 2(2%) infected only with Anti-HBc (+). Of the 16 carriers, there were 2 cases with hepatitis (ALT>= 100UI/I). In conclusion, with our findings, we noted that 8% medical students were carriers, they need an adequate information for preventing the contamination between health -care providers and patients, 54% students need urgently a vaccine for protecting themselves from the HBV infection.

A cross-sectional study was performed from April to December 1999 to evaluate the changes in antibody levels after HBV infection. 242 medical students were screened. Among these, 49 students (mean age 20.7+/-1.25 years, weight 52.3+/-8.1kg) were infected with wild HBV, as confirmed by presence of anti-HBs and anti-HBc and absence of HBsAg. In the first visit, the mean serum concentration of anti-HBs was 323mUI/mL. After 9 months, there was insignificant change in this antibody level with the mean was 303mUI/mL (p=1).

From May to December 1999, we performed a study to look for the antibody response after vaccination against hepatitis B in 112-second year medical students (97, Faculty of Medicine, Ho Chi Minh city, VietNam). We used recombinant DNA vaccine (HB VAX- II, MSD), with standard schedule (0,16 months). The healthy students (mean age: 19,7+/- 1,5 mean height 1,6+/- 0,1 m, mean body weight 51,1+/- 6,6 kg) who had neither immunodepression nor previous hepatitis B vaccination were included in this study. The sera from these were negative for HBsAg anti-HBs, anti-HBc. The good immunological response after vaccination was confirmed by the level of anti-HBs >10 m Ul/ml in the sera (blood taken 1 month after the 3rd injection). The results were encouraging: 100% students who received the vaccine got a good response with the height level of anti- HBs in the sera (average: 794+/- 306mU/ml). The level of anti-HBs was below <100mUI/ml in 2 students (1.8%), 100-< 500 in 20(17.8%),500-<1000 in 20 (17.8%) and >= 1000 in 70 (62,5%). These students had no close relationship with the age and the sex.

Plication of horizontal recti with many advantages in the treatment of strabismus has been applied by many authors in the world, but not yet in Vietnam. Objectives: to evaluate the results of this surgery that applied in Vietnamese. Methods: Prescriptive, longitudinal prospective study that had been done in Hanoi National Institute of Ophthalmology from 9/2003 to 9/2004. Results: In postoperative period, 83.3% of cases with exotropia and 89.6% of cases with esotropia are well corrected after 6 months, 100% of operated eyes are well healed with a smooth conjunctive scars and 52.62 % of operated patients have got a full binocular vision after 3 months following up. The rate of the eyes with suspected amblyopia is reduced from 18.8% to 9.8%, with moderate amblyopia is also reduced from 8.8% to 2.4% by 6 months postoperatively, but the rate of the eyes with severe amblyopia is not significantly changed after surgery. Conclusion: Plication of horizontal recti is a safe, effective method for correction of strabismus, especially when it is necessary to do surgery on many extra-ocular muscles in the same eye.

Listeria momocytogenes is a positive gram bacillus, not producing odontoblast, often seen in soil, straw and grass and plants. Listeria can infect to herbs, cooked food and cheese and paste in fridge. Listeria gets in human body by digestion of contaminated food. The disease caused by listeria is dangerous with the mortality rate can up to 30% of cases. To prevent listeria-caused diseases, food safety has to be promoted, especially for people with exposure (infants, pregnant women, immune-compromised people). Biochemical tests to differentiate Listeria momocytogenes from other forms of non-harm listeria variations help diagnose at the earliest possible stage.

Epidemiology is the study of phenomena and completions of community’s health in order to prove the determining factors and their roles and to carry out proper measures. Epidemiologists rely on statistic methods, using different sampling and analysis methods based on objectives and feasibility of the work. Epidemiology is now a valid study in college cirricullum and more and more recognized and applied.

Study 120 intravenous drug users admitted liver disease clinic and HIV clinic from April to July 2002, the results showed that reasons of 14.2% were routine examinations, the rest were fever, HIV-related conditions or symptoms of liver diseases or gastrointestinal diseases. 57% patients had transaminase level of >100 IU/l. Severe hepatocellular necrosis was remarkable in patients went to liver disease clinic. Important co-infection in 54 patients went to liver disease clinic was HIV-HBV-HVC. Intravenous drug users can be co-infected with many different viruses with severe hepatocellular necrosis, so they need appropriate treatments
