Background: Gamma irradiation has been often used for inactivating viable T lymphocytes in the blood product to prevent post-transfusion graft - vs - host disease (PT - GVHD) occurred in the recipients having immunodeficiency. But the irradiating method must be determined to minimize the reverse effects on other blood elements. Objectives: to evaluate the side effects of gamma irradiating with 25 Gy and in different ways on red cells in stored red cell concentrates. Subjects and methods: Each of 30 red cell concentrates was divided into 3 parts and treated in 3 different ways to create 3 groups of sample for studying. All the samples were stored 35 days at 4 - 6\xb0C and measured red cell osmotic fragility, hemoglobin (Hb) level in storage solution in days 1,7,14,21,28,35. Results: 1) Red cell osmotic fragility decreased and free Hb level increased with time in the samples of 3 groups. 2) Red cell osmotic fragility decreased strongly from the 28th day (p < 0.05) and free Hb level increased dramatically from the 14th day (p < 0.001) in the samples of group 2 compared to control group and group 3 with the same storage time, while there was no difference in these parameters in groups 1 and 3. Conclusion: 1) Gamma irradiation with 25 Gy affected the intact of red cells in red cell concentrates only when irradiated right after being produced and stored more than 14 days. 2) The quality of red cell would be unchanged if used immediately after irradiated. \r\n', u'\r\n', u'

Background: Benign hyperplasia prostate is a common disease in older men (over 60 years old). Transurethral resection of benign hyperplasia prostate is a method of improving symptoms with the best results, though with a high rate of complications, in which the most serious complication is transurethral prostatectomy syndrome (TURPS). Objective: The study aimed to describe clinical and para-clinical characteristics of TURPS and to define some risk factors of TURPS. Subject and methods: A descriptive, prospective study was conducted in 200 patients, who underwent TURPS, ASA I-II at the Anesthetic Emergency Department, Viet Duc Hospital from April 2007 to October 2007. To describe TURPS by observing clinical signs and serum sodium. The risks of TURPS were considered as prostate weight, operation time and amounts of used irritants. Results: The incidence of the TURPS was 7% of all resections. Clinical signs of the TURPS were nausea, vomiting, headaches, confusion and disorientation. TURPS was associated with hypotension (42.9%), bradycardia (35.7%), increased CVP (21.4%). The sodium concentration fell below normal in certain patients (64.3%). The amount of 3% Sorbitol (> 20 liters) was an independent risk factor of TURPS, but not the prostate weight or the operation time. Conclusions: The main signs of TURPS included central nervous symptoms (100%), circulatory and respiratory disorders (42.9%, 21.4%, respectively) and hyponatremia (64.3%). Sorbitol 3% > 20 liters was an independent risk factor of TURPS.

Journal of Medical and Pharmaceutical Information 2004;0(8):29-32
Background: PDA is an especially common pathological condition in premature neonates because of the anatomical structural immaturity of the cardiovascular system. There are evidence for the effectiveness of ibuprofen for closing persistent ductus arteriosus, with few adverse effects. Objectives: To determine whether oral ibuprofen treatment is effective and safe in the closure of PDA in premature infants with respiratory distress syndrome. Subjects and methods: The prospective study was conducted on premature newborns with PDA who were presented at the Department of Neonatology, National Hospital of Pediatrics. Results: A total of 32 neonates were eligible for the study. Ductal closure was achieved in 22 newborns (68.6%), the ductus was persistent after 6 doses in 8 cases (25.1%), 2 newborns (6.3%) suffered from ductal reopening after closure (after 1 and 2 doses). PDA closure was achieved with 1 dose of ibuprofen in 7 cases, 2 doses in 9, 3 doses in 4 and more than 4 doses in 4 cases. The survival rate was 81.2% (26 out of 32). 6 patients (18.8%) died from severe respiratory distress and very low birth weight (2 cases), Klebsiella sepsis (4 cases). Mortality is higher in the closure failure group (p<0.05). Conclusions: Oral ibuprofen suspension can be considered as an effective and safe alternative for PDA closure in premature newborns. Larger comparative studies is required to confirm these results.

Background:The failure of medical treatment for closure of the ductus arteriosus in very premature is still high (41%). Objectives:This study aims to evaluate the response of ductus arteriosus by color doppler ultrasound in premature infants treated with ibuprofen. Subjects and method:A pilot study was conducted at neonatal intensive care patients on 8 prernatures. The mean birth weight was 825 g (640g - 1190g) and gestational average age of 27.4 weeks of amenorrhea with respiratory distress with ductus arteriosus significantly. The average size was 1.9\xb10.3mm. Intervention: Children received the first dose of Ibuprofen 10mg/kg/day at age from 35 to 54 hours of life, and then 5mg/kg/day after 2 doses. Results:The outcome measure of the size of the ductus arteriosus was performed before each dose of Ibuprofen and 6 hours and 12 hours after each dose. At least three different measures has been taken every echocardiographie. 4 ways of evolution kinetics of turnover: 1: ductus arteriosus ferrne rapidly for 12 early hours of 1st dose (2 patients). 2nd: ductus arteriosus after 3rd dose (3 patients). 3rd: ductus arteriosus quickly after first 12 hours of 1st dose and then reopened (1 patient). 4th: ductus arteriosus not ferrne (2 patients). The size of sales decreased significantly 6 hours and 12 hours after the 1st dose of the 1st prernatures cure in 7 (87%) whatever the final outcome (p<0.05). Conclusion:The different responses from one individual to another led us to consider a Echo guide personalized therapy. A further research should be carried out to find a protocol for better value.

Background: Domestic violence is a common occurrance in every country, culture and all levels of society, and about 20%-50% of women worldwide are victims of domestic violence. In Vietnam, domestic violence had broad range of influences and has serious impacts. Objectives: To identify the factors influencing domestic violence in Yen Phong district, Bac Ninh province. Subjects and method: A cross-sectional study was conducted in 2006 on 452 married women aged 19 to 45 years, with structured questionnaire and in-depth interviews and focus group discussion. Results and conclusion: the lifetime prevalence of domestic violence was 42% and the prevalence in the past 12 month was 22.6%. The most frequent domestic violence was mental, followed by physical and sexual violence. The first 15 years of marriage was the most turbulent period of violence. There were significant relationships between lifetime violence and the education, occupation, economic status, but there was no relationship for violence in the past 12 months. The women, whose husbands were drunk, gambling and unfaithful, were more likely to be facing domestic violence than the others. The acceptance of violence by women was significantly related to violence. Those who perceived the violence by husbands were very severe then were less likely to be faced by violence than the other. In order to prevent the domestic violence, it is necessary to promote the health education, improving the awareness of women and men on gender equity and equality.

Background: hepatitis due to virus B is now one of the leading concerns in the community health care throughout the world. Vietnam was a country located in high risk areas for hepatitis B virus (HBV) infection with rate of HBV infection in the community ranged from 11.3 to 25.5%, the rate of HBsAg positive in pregnant women from 12-16%. Objectives: to evaluate knowledge and practice on HBV prevention among pregnant women in Hanoi in 2005-2006 period; to study on some related factors of HBsAg positive rate. Subjectives and Method: a cross sectional study (with analysis on knowledge and practice about HBV prevention) was carried out on 1.300 pregnant women above 28 gestational weeks at Hanoi Obstetrics/Gynecology Hospital in 2005. Results: the rates of women with knowledge about HBV prevention were 38.5% at good level, 24.4% at acceptable level, and 37.7% at unacceptable level. The rates of practice on HBV prevention were 58.5% at satisfied level and 41.5% at notsatified level. Knowledge was likely related to practice, age, educational level, and HBV positive rate. Practice on HBV prevention was also related to HBV infection. Conclusions: the rates of women with knowledge about HBV prevention at good level were relatively high. The rates of practice on HBV prevention at satisfied level were relatively low. Related factors of HBsAg positive rate: knowledge and practice about HBV prevention.

Journal of Medical Research 2008;56(4):104-111
Background: Metabolic syndrome is characterized by a group of metabolic risk factors in one person but not a real disease. For this reason, metabolic syndrome is underestimated by clinicians and individuals. Metabolic syndrome that was not detected and treated timely can cause serious diseases. Objectives: 1) To investigate the abnormal blood biochemical parameters related to metabolic syndrome. 2) To determine the abnormal ratio of these parameters. 3) To screen the metabolic syndrome among the staffs of Ha Noi Medical University. Subjects and method: 229 staffs underwent laboratory tests to diagnose for the metabolic syndrome. Abnormal blood biochemical parameters were defined as follows: Fasting blood glucose level increased 6.1mmol/l or more. Triglycerides level is 2.3mmol/l or more, HDL-cholesterol decreased to less than 1.03mmol/l for men and less than 1.24mmol/l for women. Total cholesterol level is 5.2mmol/l or more. CT to HDL-C ratio is more than 3.63 and LDL cholesterol level is 3.5mmol/l or more. Results. Rate of subjects with glucose intolerance or blood fasting glucose higher than 6.1mmol/L is 20.09%. Rate of subjects with dyslipidemia is 61.14%. Average levels of blood glucose, triglycerides and cholesterol increase with age. Number of staffs of Ha Noi Medical University have metabolic syndrome in 2007 are 32 persons (14%). M/F rate is equal and most common in persons over 45 years of age. Conclusion:There are significant number of staffs at the Ha Noi Medical University that had abnormal blood glucose and cholesterol levels related to metabolic syndrome.
