Studying on measurement of lung function and comparing the clinical symptoms with lung function change was carried out in 31 children from 7 to 15 years of age with asthma. Results: All of lung function indicators in the exacerbations of asthma children were decreased, such as FVC% and FEV1% < 80% compared with predicted, PEF and FEV1/ FVC% < 75%. There was relation between clinical symptoms with lung function. The more severe clinical signs were the more decreased indicators of measured lung function

The investigation using combination of quantitative and qualitative methods at 60 communes, towns of three districts including Quan Ba, Yen Minh (Ha Giang) and Chiem Hoa (Tuyen Quang) showed that ratio of households with hygienic privy were very low (6.5%) among 6012 investigated households in both provinces. The construction and preservation and use of the privy were not in good conditions, only 5.2% households are using hygienic privy. The situation in Ha Giang was not as good as Tuyen Quang

185 patients with severe hypertension were treated at the Cardiovascular Department, Viet Tiep Hai Phong Hospital in 2004. Results: patients with severe hypertension accounted for 20.30% of admitted hypertension patients. The mean age was 63.44± 13.64. Female is more than male. 18.33% the patients didn’t know that they suffered from hypertension, only 26.49% patients had regular treatment, specially 55.73% patients discontinued treatment. Heart disease was the most common complication, with high rate 37.85%. 16.21% patients had myocardial ischemia. 25.95% patients had arrhythmia. 93.52% patients were treated by triple-drug or fourth-drug therapy after admission, the patients’ blood pressure decreased after one hour follow up.

The research was carried out on 108 stroke patients, 108 healthy control subjects matched in age and gender at the Hue Central Hospital in 2004. Results: Increasing the mean level of homocystein in blood is new risk factor of stroke. It’s maybe an independent risk factor or combining with other risk factors of stroke (especially hypertension). The rate of hyperhomocysteinemia is higher in patient group than in control group. There were statistically significant association between the mean blood homocystein level with amount risk factors of stroke (age, smoking, blood pressure, uremia, creatininemia, HCT, platelet). Especially, the mean homocystein level in blood had a negative correlation with Glasgow scores. Quantifying the homocystein level in blood of stroke patients can predict the severity of conscious impairment

The cross-sectional study with interviews people who exposed to chemicals for plant protection at 528 households in vegetable areas in Thai Nguyen city showed that: the rate of people directly exposing to pesticides in study group is very high (34.8%). 55.3% of people exposing to pesticides are women, 20% out of them under 18 and over 60 years old. Knowledge and practice on safety in using pesticides are even low. Common manifestations: tiredness, headache, dizziness, numbness account for 3.1-48.1%.

The study was conducted using combination of cross-sectional, quantitative and qualitative methods at 82 communes and towns of Quang Trach and Bo Trach districts (Quang Binh), Phu Loc district (Hue). Results: the supply and use of water in 8180 households investigated were relatively good in quantity and acceptable quality. Two water supplies were used with high rate were deep well (59.3%) and drilled well (19.2%). However, it is necessary to propagandize awareness of environmental sanitation in public such as choose safe water supplies (tap-water), stores water in clean storage tools, and exploit running-water far away from polluted sources

The study used WHO's questionnaire to identify the prevalence of epilepsy and its causes in Thai Bao commune of Gia Binh distric, Bac Ninh province, a community with high risk of cysticercosis infection. Results: There were 71 cases (41 men, 30 women) out of 6617 people living in the country suffering epilepsy. The prevalence of epilepsy was 10.7%, 52 cases were active epilepsy. The lowest age group suffering epilepsy were under 10 years old (5.7%), increased in higher age group and significantly increased at over 40 age group (over 17%). 64.79% of patients had generalized seizures, 23.94% had partial seizures and 11.27% of patients had unclassifiable seizures. Age groups under 10 and 41-50 had high risk of epilepsy onset. 49.3% (35/71 patients) had risk factors causing epilepsy, out of them 14 were due to neurocysticercosis. 62% patients were examined, managed and treated

Studying on arterial blood gas of 50 children with acute asthma and comparing with clinical symptoms showed that there was closely relation between symptoms such as cyanosis, fast breathing, severe breathless, talks in word or phrases with pH, PaCO2, PaO2, SaO2 and HCO3. The stimulations which related closely with hypooxygenemia were PaO2, SaO2 and pH. Tugging respiratory muscle related to changing pH in blood. There was not relation between blood gas indicators and signs such as rapid pulse and wheeze
