Background: Heart failure is a common clinical condition and is the late stage of most cardiovascular diseases. Heart rate disorder is one of the causes of deaths in patients with chronic heart failure. There is few number of studies on Heart Rate Variability (HRV) in Vietnam. Objective: To study the change of HRV time in patients with chronic heart failure. Subject and Method: A prospective, descriptive and cross-sectional study was carried out on 105 subjects including 73 patients with chronic heart failure and 42 normal persons as controls. Time domain measurements of HRV were calculated from 24 hour electrocardiographic Holter (Holter WIN P-V, USA) on all 105 subjects. In the chronic heart failure group, there were 51 men and 22 women with the mean age of 62.8+/-11.2, control group including 30 men and 12 women with the mean age of 61.5+/-5.7. Results and conclusion: (1) There was a decrease of time domain of HRV showed the decrease of parasympathetic tone in patients with chronic heart diseases. (2) The higher degree of heart failure, the lower the time domain of HRV.

Background: Hypertensive with impaired fasting glucose is the basic expression of metabolic syndrome. Objectives: To study the IR and the correlation between Fasting Plasma Insulin (FPI) and Fasting Plasma Glucose (FPG) concentration in hypertensive patients with Impaired Fasting Glucose (IFG). Subjects and method: The descriptive, cross-sectional study was carried out on 38 hypertensive patients with IFG (IFG group) and 30 hypertensive patients without IFG (control group). The data were collected and analyzed by SPSS 11.5 software. Results:The FPI and IR index in the IFG group were 14.6+/-5.2 micro mol/ml and 3. 94+/- l.40, respectively, higher than in the control group (9.6+/-4.2 micro mol/ml and 2.17+/-0.99/ respectively) with p<0.00l. There was a positive correlation between FPI and FPG systolic blood and diastolic blood pressure/ with correlation coefficients were 0.4/ 0.48 and 0.46/ respectively (p<0.00l). Conclusion: There was an increase of FPI and IR index in the hypertensive patients with IFG compared to those without IFG. \r\n', u'\r\n', u'

Background: Dengue fever remains a major public health problem in Vietnam. It was transmitted through two main Aedes species, namely Aedes aegypti and Aedes albopictus in which Aedes aegypti played the predominant role in transmitting the dengue viruses (accounted for 94% of the Aedes genus).Different groups of insecticides have been widely used in the community. As a consequence, it increased the resistance level of Aedes vectors to the insecticides. Therefore, a new synthesized insecticide was required for future control and prevention of dengue epidemics. \r\n', u'Objectives: To evaluate the efficacy of Cynoff 25 ULV in suppressing Aedes species in Vietnam. \r\n', u'Subjects and methods: The study was conducted in the entomology laboratory and in the fields of Ha Tay province. ULV spraying was implemented in Hiengiang commune, Thuongtin district, in comparison with a control area, Van Mo commune in Ha Dong town.\r\n', u'Results and conclusions: : Cynoff 25 ULV had a high efficacy that kills over 90% of 2 dengue vector species, namely Aedes aegypti and Aedes albopicctus after 24 hours exposure at the distance of 30 meters from the brass nozzle of a STIHL SR 400 sprayer. In the field trials, Cynoff 25 ULV also had high efficacy in killing Aedes species, e.g. 100% of Aedes species were killed after spraying and the effects lasted for 3 months for Aedes aegypti and one month for Aedes albopictus species. The insecticide had no side-effects or any other adverse effects to humans, livestock and the environment in the intervention areas. \r\n', u'

Background: Video-assisted thoracoscopic surgery (VATS) is a now new, effective approach in diagnosis and treatment of thoracic diseases. Objective: To summarize and evaluate the results of VATS for mediastinal tumors. Subjects and method: A retrospective study included patients with mediastinal tumors who performed VATS in Viet Duc Hospital from March 2006 to August 2007. The measurements about age, sex, hospital-admitted reasons, tumor\u2019s size and location, outcomes and complications were analysed. Results: There were sixteen patients, included 9 males and 7 females. The patients\ufffd?average age was 35.3 years (ranged from 16 to 72 years). Clinical characteristics of mediastinal tumors were chest pain (11 cases), trouble breathing (4 cases), cough (2 cases). CT scanner detected mediastinal tumors in all patients (16 cases). Pathologically, 15 patients had benign tumors and only one had malignant tumor. The average time for postoperative drainage withdrawal was 3.0625 days (ranged from 2 to 5 days). The average time of hospital stay was 5 days (ranged from 3 to 11 days). There was no postoperative complication. Conclusion: VATS for mediastinal tumors obtained good outcomes. This was a selective method with many advantages for mediastinal tumors.

Background: Acute lower respiratory tract infection, mainly pneumonia, were the main reasons cause death for children under 5 years old. Objectives: Determine the isolated rate of bacteria inpatients under 5 years old with acute lower respiratory tract infection in Ha Noi and antibiotic resistance of pneumococcal isolated form patients. Subjects and method: Patients under 5 years old with acute lower respiratory tract infection in National hospital of pediatrics and Bach Mai hospital from 01/2002. Using quantitative culturedand PCR method. Results: Out of total 164 patients with lower respiratory tract infection, there were 91 diagnosed pneumonia by chest X-ray, 73 cases of acute bronchitis. 73,6% of the pneumococcal isolated were penicillin resistance (gPRSP) with different genes such as pbp 1a+2x+ab. Most of the S.pneumoniae strains were serotype 19F or 23F. There were no statistic differences by comparison charactersistics of weight, vessel, subclinical symptoms such as: dissolved oxygen level (S\xac\xacp\xac\xac\xac\xacO\xac2\xac), the amount of leucocyte in blood. However, temperature of pneumonia patients was higher than bronchitis patients, breathing of pneumonia patients was also faster than bronchitis patients. Isolated bacteria with amount \ufffd?106 cfu/ml was H.influenzae, S.pneumoniae and Moraxell catarrhalis in pneumonia group, bronchitis group was 28,8% and control group was 17,1%. Conclusion: Penicillin, erythoromycin and co-trimoxazole resistance rate of S.pneumoniaein patients with acute lower respiratory tract infection was high. Quantitative cultured method has prognostic value in diagnosis pneumonia.
