Sex ratio at birth in Viet Nam 2006

Background: In recent years the sex ratio at birth in Viet Nam is imbalanced, with the number of male births being higher than that of female births. Objectives: To describe the trend and distribution of sex ratio at birth by time and geography, and investigate the relationship between sex ratio at birth and abortion ratio in 2006. Subjects and method: The study was conducted in 3.840 communal health stations, 723 district hospitals/polyclinics and 132 provincial and central hospitals with total of 1,095,064 births, occupied 78% of births over the nation in 2006. Result: The male/female sex ratio varies between areas, with the ratio being higher in rural than in urban and higher in the North \u2013East and North-Central regions than in the rest of country (p<0.05). Conclusion: There has been the clear imbalance of sex ratio at birth since 2002 (varying from 110 to 113), as well as the significant imbalance of sex ratio at birth by provinces. High imbalance of sex ratio at birth is related to the high abortion rate in these provinces. Viet Nam needs to implement strong measures/actions to avoid the same situation as in China and India.

Prevalence of the first and second molar caries and risk factors among students of Khuong Thuong primary school, Dong Da, Hanoi, 2005

Background: Dental caries are the most common diseases in Vietnam and the World. There are some risk factors influencing diseases.Objectives: (1) describe dental caries prevalence in first and second molars, and (2) risk factors of the first molars. Subjects and method: The cross sectional study was applied with sample size of 377 students in Khuong Thuong primary school in 2005. Structured questionnaries were used to collect information on individual characteristics, eating habits and dental hygienic practices. Results: prevalence of the below first molars was highest (35,3%-36,5%). The prevalence of the above first molars was 8,4%. The logistic regression analysis show that students who had poor tooth brushed practice have higher dental caries prevalence significantly. Hygiennic dental education is important and needed to reduce dental caries.Conclusion:The prevalence of the first molars was higher than the prevalence of the second molars. The prevalence of the first below molars was higher than that in the first above molars. Wrong tooth brushing was a determinant of dental caries.

Assessment of result of interlocking intramedullary SIGN nailing in treatment of femoral shaft fracture in adult patients at Viet Duc hospital from 2004 to 2005

Background: Femoral shaft fracture, in company with the development of morden society and the increase in means of transport, is increasing in the number of case and the complicated degree of injury. Objectives: 1. To note indication for interlocking intramedullary SIGN nailing in femoral shaft fracture in adult patients. 2. To assess result of interlocking intramedullary SIGN nailing in treatment of femoral shaft fracture in adult patients. Subjects and method: A prospective, descriptive study was conducted in the 40 patients between the ages of 17 and 80 who were dignosed femoral shaft fracture caused by injury and operated for bone union by interlocking intramedullary SIGN nailing at Viet Duc hospital, from April/2004 to July/2005. Results: In this study: 5 patients with I degree fracture (12.5%), 20 with II degree (25%) and most of patients with III and IV degree fracture (62.5%), of which 14 patients with IV degree (35%). Because the SIGN nailing\u2019s structure was solid, so it had a good capacity for patient\u2019s weight. 4 weeks after operation, 85% patients were able to move around without crutches. There was no complications. Conclusion: SIGN nailing enables surgeons to drive interlocking intramedullary nailing for long bone without image intensifier. It also enables both surgeons and patients to appoarch modern, high effective methods without needing expensive machines.

Autologous bone marrow transfusion to treat the tibia diaphyseal nonunions

Background: Bone marrow stem cells with their plasticity can be used to replace and repair the other damaged organs and tissues, so they can also be used to obtain bone healing of nonunions. Objective: to evaluate the results of percutaneous autologous bone marrow grafting to treat the tibia diaphyseal nonunions. Subjects and methods: 12 patients with noninfected nonunion of the tibia were diagnosed and treated in Viet Duc Hospital. About 250mL of marrow was aspirated, then separated and concentrated by density gradient centrifugation. The final mononuclear cell mass containing stem cells and progenitors was washed in 30ml of 0.9% NaCL and then injected into the damaged sites. Patients were evaluated by clinical and X-rays examinations with at least 6 months follow-up. Results: None of the patients had post - op complications. Bone union was obtained in eleven of the twelve patients (91,7%) at an average of 15,3 weeks (range, 9 - 30 weeks), the bone marrow grafts used for these patients who had bone union contained a mean of 5,65 \xb1 3,74 x 106 (0,95 - 11,73 x 106) CD34(+) stem cells in total. Conclusions: Percutaneous autologous bone - marrow grafting is a minimally invasive alternative and a simple, effective, safe method for the treatment of the tibia diaphyseal nonunions with the comparative bone healing rate. \r\n', u'\r\n', u'

Situation of extremity injury caused by traffic accident in Viet Duc hospital from 2000 to 2004

Background: Situation of extremity injury caused by traffic accidents and occupational accidents are increasing in Vietnam. Therefore, the prevention and fight against these accidents are one of the key objectives to reduce the burden on the families of victims as well as for society.

Results: Extremity injury was common seen in people of working age (78.1%), men more than women (2.76/1 ratio), left foot more than right foot and it was common been in multiple fracture situation due to complex mechanisms of injury (50.3%), alone extremity injury (49.7%). The lower extremity injury was more common seen than upper extremity injury. Open fracture injury (27.3%), in which open fractures in lower extremity were more common seen. Open fractures in both 2 leg bones was the most common seen, accounted for 57.4% among total of open fractures. Amputation accounted for 8.3% among all case of open fractures and 2.3% among all case of extremity injuries.
