Study on 732 Australia dyspeptic patients with infection of H. pylori, in which there are 96 Vietnamese immigrants. Results: Among dyspeptic patients, the prevalence of H. pylori infection in Vietnam (63.7%, 95%Cl: 62.7-64.7%) was statistically higher than that in Australia (46.4%, 95%Cl: 46.0-46.8%). The spectrum of GD diseases in Vietnamese dyspeptic patients is very different from that of Australian patients with higher DU and GU and lower GORD and Barrett's epithelium. The prevalence of H. pylori infection in Vietnamese patients in Hanoi is not different from that of Vietnamese immigrants in Australia. In contrast, GoRD is found about 7 times more frequent in Vietnamese immigrants compared with Vietnamese patients living in Hanoi.

The results of Danver test and Raven test on 238 > 6 years old of age children with cerebral palsy in HaTay province were assessed. With Ravent test, only 2% among them had not mental retardation, but 98% had mental retardation in various levels. Among the subjects of floppy form of cerebral palsy there is not any case of normal mental level, but a light level of retardation. With Denver test, 26% of cerebral palsy children had got normal development in comparing with the other. But there are different levels of retardation in various domains, 97% of cerebral palsy children got retardation in mobility domain, 85% in individual and social domain, 61% in adaptative mobility and 53.7% in laguage domain

In studying 155.633 subjects living in Ha Tay, among them 238 suffered from cerebral palsy, 54% of cases are male, 46% female. Gender ratio male/female: 1.16, varying with age groups. The highest 1.9 in under 10 years of age group. The lowest 0.2 of > 50 years of age group. Cerebral palsy patients mean age are 18.2 versus 28.3 of normal population in this survey. Average age and maximal age of cerebral palsy patients in Ha Tay are lower than those of the patients in developed countries

The study was conducted at Hanoi Obstetrical and Gynecological Hospital, combining quantitative and qualitative research methods. Results: the study showed that there was a tendency for pregnant women to over-use ultrasound scanning. The reasons for this included women’s perceptions of the usefulness of ultrasound scanning, their serious worries for the fetus, as well as the effects of the market economy on this health service. Over-use of obstetrical ultrasound scanning was not only related to the perception, demands and psychology of pregnant women, but also to socio-economic changes associated with the economic reforms and the liberalization of the health care system.

Olyset net sunk with 2% permethrin was used in Hai Duong, Hai Phong, Thai Binh. The rate of density index and house index were decreased from 0.23 and 23.3 to zero and persisted by 9 months. Breteau index and larve-house index was also decresed from 8.3 and 6.7 to zero. Olyset net showed its effect on Aedes aegypti and in various mosquitos and insects

This study was carried out in 72 healthy adults of working age, non-smoking, and non-exposure to occupational carbon monooxide. The results showed that substances coming from factories did not pollute their indoor environment at home. The hemoglobin (Hb) contents of examined persons was within the normal range of 122-165 g/l. Average CarboxyHemoglobin (HbCO) was 0.789+/-0.382%, ranging 0.000 to 1.500%.

Study on the pathogens of septicemia in order to choose appropriately antibiotics in the treatment. Subjects were 138 septicemia patients admitted to Institute of Infectious and Tropical Diseases from June 2001 to May 2002. All patients were taken their blood samples to isolated and culture bacteria during they had high fevers or before taking antibiotics. Some pathogenous bacteria were isolated and identified in 20.3% patients. The most common species were S. aureus (accounted for 42.4%), followed by Enterobacteriaceae (28.8%)

Aedes aegypti mosquitoes had been collected at field of some Northern provinces between 2001 and 2004 for studies of their susceptibility to insecticides. It was seen that: all of tested mosquitoes dropped immediately 100% and 100% killed after 24 hours. The results showed that all tested mosquitoes were highly susceptible to insecticides, such as permethrin, lambda cyhalothrin, and malathion from 2001-2004 in Northern region. The provinces participate in the test was up fro 5-7. Using the insecticides to kill Aedes aegypti by ULV spraying was effective in Northern provinces in Vietnam. It is adviced to send mosquitoes and lavae in June and July when the density of mosquitoes and lavae is high. Therefore, expanding studies to other provinces throughout the country to identify susceptibility of Aedes aegypti to insecticides is very necessary for Dengue Hemorrhagic Fever vector control.
