Recently we have made a research in 21 patients including 11 males and 10 females, aged from 2-37, whose deep burn area were 5-45% the whole body. These patients had been treated in NIB. (National Institute of Burn) and had totally experienced 32 operations of auto-Graft lay frog graft overlay widely meshed skin grating (the advanced technique sandwich). Though this research, we come to the conclusion that: (1) Autograft under lay frog graft overlay widely meshed skin grafting technique can enlarge the graft area and save the healthy skin. Which is of specific significance to the patients who have the area of deep more burn than 20% the body area. (2) This technique helps the auto graft to live better and the tissue to develop well. It reduces the patient's pains and the blood loss when changing the Bandages.

101 burn sepsis patients, aged 0.5-68 years were treated in the National Institute of Burn during March 1998 to September 2002 period mortality due to burn sepsis was 53.5%, mortality due to P. aeruginosa was 60%, higher than to S. aureus (31.6%). The results of treating were related closely to general burn surface, deep burn surface, infecting germs. Intensive surgery and efficacy use of antibiotics promoted the possibility of survival

A study was conducted on 28 burning sepsis patients treated at the National Institute of Burn. Results showed that their capacity of bacteriophage and of EA rosette formation of polynuclear neutrophil white blood cells was reduced in comparing with healthy patients and with other no burn sepsis patients, as well as burning no sepsis patients. Their white blood cells function restored gradually with the improvement of the condition. Thus the capacity of bacteriophage and EA rosette formation have reflected the state of burning conditions, and their monitoring can help the evaluation and prognosis

Background: Beer is produced to meet people\u2019s demands. Sanitation, old technology, poor knowledge on hygiene and safety of workers is still limited. Objectives: This study aims to learn the real situation and solution to improve the practical knowledge on food hygiene and the safety of workers at beer-producing enterprises in Ha Noi. Subjects and method: The descriptive, cross-sectional study on wokers at beer-producing enterprises in Ha Noi.The data were collected from designed questionaires and analysed by Epi.infor 6.04 software. Results: The general knowledge rate on hygiene food safety of workers is 42.5%; In there, the knowledge rate on environmental hygiene of workers is 45.6%; the knowledge rate on work instrument hygiene of workers is 46.4%; the knowledge rate on personal hygiene of workers is 37.7%; the knowledge rate on food hygiene of workers is 50.9%; the knowledge rate on food poisoning of workers is 76.3%; Conclusion: There is a relationship between the practical knowledge on hygiene food safety, age and work duration.

Background: Worldwide, the beer industry has developed from 2% to 8% per year during 1990 and 2000 and the number of production surpassed 140 billion liters per year in 2001. Beer is not widely recommended for the population but the fact is consumption is on the increase. Objective: To evaluate the real situation of food safety conditions and hygiene safety requirements for beer at beer production enterprises in Hanoi and study various related factors to propose appropriate solutions to improving the food safety hygiene. Subject and methods: A cross-sectional, analysis investigation was conducted in 70 private beer-production enterprises in Hanoi in 2007. Results and Conclusion: The general rate with good food hygiene safety condition was 68.6%. Among them, the good environmental hygiene condition was 82.9%; good drainage condition was 75.7%; the work area hygiene condition meeting requirements was about 74.3% (with wall and floor hygiene regulation at 57.1%); food hygiene condition meet requirement about 95.7%; good work instrument hygiene condition was 72.9% and the lowest rate of work instrument hygiene regulation was 68.8%; good personal hygiene was 80%. The bad personal hygiene and environmental hygiene condition increased the risk of food hygiene quality that did not meet the requirement by ten-folds and thirteen-folds, respectively. The bad personal hygiene condition increased the risk of tool hygiene that did not meet the requirement by 5.5 folds.

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.

Objective: Female sex workers (FSWs) are at high risk of human papillomavirus (HPV) infections and cervical cancer due to their high number of sexual partners. The objectives of this study were to determine the prevalence of HPV and identify risk factors for high-risk HPV infection among FSWs in Hanoi and Ho Chi Minh City (HCMC), Viet Nam. Methods: A cross-sectional study was conducted in Hanoi and HCMC between December 2017 and May 2018. We surveyed and screened 699 FSWs aged ≥18 years for HPV infection and abnormal cytology. A multivariable modified Cox regression model was used to determine risk factors for high-risk HPV infection. Results The overall prevalence of any HPV, high-risk HPV and HPV-16/18 infection in the 699 FSWs was 26.3%, 17.6% and 4.0%, respectively, and were similar in both cities. Multiple infections were identified in 127 participants (69.0%).HPV-52 was the most prevalent (7%), followed by HPV-58 (6%). Abnormal cytology was detected in 91 participants (13.0%). FSWs who are divorced (adjusted prevalence ratio [aPR]: 1.96, 95% confidence interval [CI]: 1.01–3.81), widowed (aPR: 3.26, 95% CI: 1.49–7.12) or living alone (aPR: 1.85, 95% CI: 1.01–3.39) were associated with a higher prevalence of high-risk HPV infection.
