Background:Pulmonary disease is still the main reason cause diseases and mortality for preterm babies. Objectives:This study aims to evaluate of the clinical efficacy of high-frequency oscillatory ventilation in the treatment of preterm infants who have seriously respiratory distress syndrome required mechanical ventilation. Subjects and method:A prospective clinical trail was conducted at Neonatal Unit of Tu Du Hospital from 1st December 2005 to 30th November 2006. Intervention: Patients were randomized to high-frequency oscillatory ventilation (20 patients) or conventional mechanical ventilation-CMV (59 patients). High-frequency oscillatory ventilation(HFOV) was used in high lung volume strategy. Results:The two groups of patients were similar in demographic distribution of birth weight, gestational age, gender, surfactant after birth. Patients on HFOV were ventilator \ufffd?dependent (2.14 \xb1 1.76 vs 3.48 \xb1 2.70 day. p=0.004) and respiratory pressure support (4.01 \xb1 2.23 vs 6.55 \xb1 day. p =0.02) for a shorter time than patients on CMV. Conclusion: First intention HFOV with high volume strategy shortened the time of ventilation and pressure support in preterm infants with seriously respiratory distress syndrome. In the future, it will be necessary to have the tremendous research for the efficacy of HFOV in order to decrease the ratio of bronchopulmonary dysplasia of infants who have seriously respiratory distress syndrome required mechanical ventilation.

Introduction: Smoking amongst medical students is rather common practice. According to a WHO report in 1989, the rate of smoking among the students of Hanoi Medical University was 38.3%. However, there has not been any investigation aimed at reevaluating the smoking situation among students of this university.\r\n', u'Objectives: To understand the smoking situation and factors that influences the students of Hanoi Medical University. \r\n', u'Subjects and methods: A questionnaire on tobacco use among youths, which was documented by the Institute of Global Tobacco Control, is used to collect the data. \r\n', u'Results: The smoking rate is 23.6%, (43.4% in men versus 1.3% in women). Average age of first use is about 19 years of age. Smoking trend increases across the age groups and academic years, while the intention of quitting cigarette decreases across age cohorts. 4 factors affecting smoking are belief, attitude to cigarette control, exposure to family and friends that smoke. The relationship between knowledge and smoking is not statistically significant. \r\n', u"Conclusion: Smoking among medical students in Hanoi Medical University is relatively prevalent. Early impaction is necessary to promote quitting cigarettes. Impact on knowledge is not enough; it also needs to focus on the surrounding environment of students through their family members and friends. Like direct interventions on the students' family and friends as both receivers and providers of intervention. Consolidating beliefs and attitudes to tobacco control also plays a critical part. \r\n", u'

Background: Smoking is a well-known cause of many diseases. The rate of smoking in Vietnam was 38.8%. Smoking among medical students is also common, although they have to set an example for ordinary people. Objectives: To describe the smoking situation among the students of Hue Medical University (HMU) and determine some of the factors relating to their smoking behaviour. Subjects and method: A cross-sectional study was carried out from January to October 2004 on 1470 medical students of HMU in the academic year 2003-2004, using a questionnaire of the Institute of Global Tobaco Control on tobaco use among youth. Results: Overall smoking rate was quite high (35%), predominantly in men (58.4% in men vs. 13.4% in women). The mean age of first use was nearly 19 years old. The trend and extent of smoking increased with age groups and academic years. Older students tended to display a higher intension rate of quitting cigarette. The 5 factors related to smoking behaviours were as followed: knowledge of socioeconomic hazards of smoking; attitudes when a cigarette offered by close friends; attitudes when exposed to a smoking person; having close relatives smoking; and having close friends smoking. Conclusion: Smoking among Hue medical students was prevalent. It is necessary to have early interventional impacts on the environment around them through their friends and relatives, and to encourage the positive attitude of medical students in the cigarette prevention and control. It is also needed to conduct a longitudinal study to assess the trend of smoking and quitting over the time of these students.

Background: Smoking in health staffs is a essential issue to be concerned. In Europe, the rate of smoking in male and female doctors were 30 - 54% and 40%, respectively. Because of the high rate of smoking in health staffs, the prevention programs should focus on promoting interventions to reduce smoking rate in healthstaffs because they are people who cause negative effects to patients and community. Objectives: To investigate smoking patterns, compare knowledge, beliefs and attitudes and identify predictors of smoking status among health staffs in Bach Mai hospital. Subjects and method: This was a cross-sectional described epidemiological study by using the questionnaire of a global survey (modified accordance with Vietnam's conditions) on tobacco use among health staffs was adapted for data collection on a sample of 656. Data was analyzed by SPSS 10.0 software. Results and Conclusion: Overall smoking rate is fairly high (~21%), dominantly among males. Physicians and dentists display a greater smoking proportion than nurses, in among over \ufffd?30 \ufffd?year \ufffd?old cohort than among less \ufffd?30 \ufffd?year \ufffd?old cohort. One main predictor of smoking is belief of health staffs on their role as non \ufffd?smoking exemplary.

Background: Health professionals set important examples through their behavior to their patients, so they need to have enough knowledge on the harmful effects of smoking. Some studies already exist on smoking among the health professionals in Bach Mai Hospital and Hue Central Hospital, but there were no such studies in the Can Tho Central Hospital. Objectives: To investigate the smoking status and identify several factors relating to cigarette use among health professionals at Can Tho Central Hospital. Subjects and method: Cross-sectional descriptive study using adapted questionnaire from a global survey on tobacco use among health professionals. Results: Overall, the smoking rate was approximately 6%, no higher than the results from other studies. It was predominant among men. Physicians display a greater smoking proportion relation to nurses, with the highest rate in the group aged 30 to 39 years of age. People who do not smoke are more likely to demonstrate a better knowledge base, belief and attitude to smoking than those who smoke. One major predictor of smoking is attitude towards tobacco control; however, a no smoking policy inside the hospital is not significantly associated with the practice of smoking. Conclusion: The smoking rate among health professionals from Can Tho Central Hospital is much lower than that among other professions and among health professionals in Bach Mai and Hue Central Hospital. The findings highlight the importance of promoting a positive attitude towards tobacco control initiatives in order to reduce smoking among health professionals at hospital settings.

Background: Flu and avian flu in humans are events in a number of countries all over the world. In Vietnam, there were some investigations on knowledge, attitude and practice for preventing flu and avian flu on several groups of the population and pharmacists in Tra Vinh province. However, there is no research for this issue in Hanoi city while the evident need for the planning of public health programs is required. Objective: To describe knowledge and identify the requirement of flu and avian flu information among pharmacists in Hanoi city. From that, some recommendations for intervention programs are proposed. Subject and methods: A cross-sectional study was conducted on 143 pharmacists in Hanoi city with a structured questionnaire of knowledge and requirement of flu and avian flu information from October, 2007 to January, 2008. Results and Conclusion: Generally, knowledge on flu and avian flu is not yet comprehensive and sufficient. Requirement for flu and avian flu information was quite in demand, especially via television, capacity building training, having more communication materials and experience exchange workshops. Several interventions need to be directed towards: comprehensive communication on flu and avian flu to pharmacists, which aims to help them understand sufficiently and comprehensive about flu and avian flu; capacity improvement for pharmacists should pay attention to several channels such as television broadcasting communication, short-term training, disseminating relevant materials and perhaps experience exchange through seminars.
