Pseudomonas aeruginosa is resistant many antibiotics currently, including new generation, broad spectrum antibiotics that were very effective with other bacteria. Thus, it's difficult to treat P. aeruginosa infection with these antibiotics. Author collected P. aeruginosa strains from some hospitals in Hanoi, tested with more antibiotics in order to determine antibiotic resistant rate and types, to orient some mechanisms of antibiotic resistance of P. aeruginosa. Materials is 97 strains of P. aeruginosa isolated from blood and pus of patients treated at Bach Mai Hospital and National Institute of Burn from August 2002 to November 2003. Method: disk diffusion antibiotic sensitivity testing (Kirby - Bauer test). Results: Isolated P. aeruginosa strains are multiple antibiotic resistant (8 of 16 antibiotics), especially hospital infection strains are resistant 100% of tested antibiotics. It showed the potential roles of some enzymes such as penicillinase, cephalosporinase, AAC(6), ANT(2")-1, and ANT(2") enzymes that inhibit effects of antibiotics in bacterium cell

Objective: To determine the factors influence height and weight growth of pupils over 5-years follow-up. Subject and method: 156 pupils of Ngu Binh primary school in Hue city were followed up from 1998 to 2002 some indices (age, weight), interviewed and determined variables. Results: some factors influenced height and weight growth of pupils were: nutritional status (malnutrition), 3rd born child in family, household with more than 2 children, poverty, lack of daily provided energy

Objective: To determine the predictive value of mortality of Apache II and SAPS II for ICU patients within the first 24 hours of hospitalization. Subjects: all patients treated at ICU, Bach Mai Hospital from December 1st 2000 to May 31st 2001 (6 months). Method: cross-sectional study. Results: there is a positive correlation between mortality rate and Apache II and SAPS II scores. The risk of mortality predicted by Apache II and SAPS II was in accordance with real mortality. Apache II and SAPS II aren't accurate to prognosticate mortality for individual

Objective: Rapidly evaluate and determine food and nutrition security situation in 8 communes of 3 districts Dak Rong, Cam Lo and Hai Lang, Quang Tri province, to provide necessary information for full survey, propose interventions in order to improve household food and nutrition security situation. Method: cross-sectional, rapid appraisal. Results: rate of poor household is high (45.8%). Infrastructure system, especially agriculture, in Dak Rong is very poor. Pre-harvest rice shortage and hunger still occurs commonly among poor households in 3 districts, especially in Van Kieu/Pako households (rice shortage occurs 4-6 months/year in average), where the number of malnourished children CED mothers are very high

Objective: To evaluate the decrease of pulmonary function in patients with respiratory distress in order to help physicians give appropriate indication of oxygenotherapy at home with appropriate doses. Subject: 37 patients and 20 healthy people in control group. Results: There isn't any change in heart rate, FEV1, walking distance, and SaO2 after walk test in healthy people. Elevating in radial artery pulse (+50 in male, +55 in female) represents increasing the need of oxygen during exercise. SaO2 decreases significantly. PaCO2 reduces. Patients can't walk as long as the healthy. Evaluting SaO2 decrease after walk test can help physicians give appropriate indication of oxygenotherapy at home with appropriate doses

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 mortality was low (1.62%). There were no treatment sequelae

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 rate of nerve and dermal diseases is relatively high
