A meta analysis was conducted on 322 projects of medical research showed that: 62.72% at basic level, 25.16% at ministerial level and 12.11% at national level. Among them 83.54% were the research on applied sciences, 38.20% on descriptive sciences. Data were collected experimentally. 65.53% new technilogies and sciences have been applied and developed, while 28.57% of applied researches and 53.65% of experimental researches. The results have contributed positively in solving the critical problems of disease control and the promotion of public health.

Background: Deltoid contracture can be a congenital or acquired condition. There were not any reports on deltoid contracture in English literature until 1960. In 2005 there were 170 children presented at the Viet Nam Pediatric Institute with deltoid contracture. These children came from different provinces, nationwide. The numbers of children who have this condition is increasing, but there were few studies on this problem in Viet Nam. Objectives: To identify the prevalence of deltoid contracture in Viet Nam in 2006-2007. Subjects and method: A cross-sectional study was done in 8 provinces representing for 3 geographic regions of Viet Nam., included Ha Noi, Ha Tay, Thanh Hoa and Lang son in Northern, Ha Tinh and Da Nang in Central and Tien Giang and Can Tho in the Southern region. 29,696 people aged from 1 to 60 years old at the baseline were involved in the study. The subjects were examined to identify the deltoid contracture based on defined criteria. Results: The prevalence of disease was 0.65% (0.83% in men and 0.51% in women). The rate was highest in the group of 6-10 years of age (1.81%). The prevalence was 0.82% in rural and 0.31% in urban area. Cases were found in all but 4 provinces (Da Nang, Tien Giang, Can Tho and Ha Noi) Conclusion: The prevalence of Deltoid contracture in Viet Nam was 0.65% in 2006-2007. It was more likely to occur in men than in women, in age group of 6 \u2013 10 than in other groups and in rural than in urban area.

Background: Deltoid contracture can be congenital or acquired. A cross-sectional study has been done in 8 provinces representing three regions in Vietnam. These are Ha Noi, HaTay, Thanh Hoa and Lang Son in the North, Ha Tinh and Da Nang provinces in the central, Tien Giang and Can Tho provinces in the South of Vietnam. Objective: To identify the risk factors of Deltoid contracture in Vietnam from 2006 - 2007. Subject and Method: 29696 people aged from 1 to 60 years old at the time of the survey were examined to diagnose the Deltoid contracture as well as being interviewed by structured questionnaire. Results: There was significant association between contracture of Deltoid muscle and some factors. These are antibiotics injection into the Delta muscle at 0 - 5 years old: OR = 2.93 (1.435,8); Antibiotics type (streptomycin) was injected at 0-5 years old: OR = 45.2 (13.1 - 167); having cicatrix: OR = 73.4 (46.1 - 116.9). There was no significant association between Deltoid fibrosis and vaccination (position and administration). Logistic regression was done to find that antibiotics injection into Delta muscle at 6 - 10 years old and antibiotics type (streptomycin) were significantly associated with Deltoid contracture. Conclusion: Risk factors of Deltoid contracture in this study were antibiotic injection at aged 0 - 5 years old, antibiotic type (Streptomycin) and having cicatrix. There was no significant association between Deltoid fibrosis and vaccination (position and administration).
