Background: Injuries to the pancreaticoduodenal complex present a significant challenge both in diagnosis and management. The retroperitoneal location of the pancreas means that it is not a common site of injury, but this also contributes to the difficulty in diagnosis. Objective: To evaluate changes of serum amylase level before the operation of pancreaticoduodenal injuries. Subjects and method: Prospective analysis of 156 patients with pancreaticoduodenal injuries from January 2000 to December 2006 was measured serum amylase level at admission. The factors analyzed in the study included age, gender, time elapsed from injury to admission, type of pancreaticoduodenal injuries according to The American Association for the Surgery of Trauma 1990. Results: The serum amylase level was found to be abnormal in all patients admitted more than 3 hours after trauma. Various comparisons between patients with elevated (78.2%) and nonelevated (26.3%) serum amylase levels showed the statistical significance solely of the time elapsed from injury to admission. The major factor that influenced the serum amylase level on admission appeared to be the time elapsed from injury to admission. Determination of the serum amylase level was no diagnosis within 3 hours or less after trauma, irrespective of the type of injury. Conclusions: To avoid failure in the detection of pancreaticoduodenal injuries, the authors advocate determination of serum amylase levels more than 3 hours after trauma.

Background: Coordinating between soldiers and people bring significant results in protecting healthy for soldiers and people in malaria epidemic area.\r\n', u'Objectives: To evaluate epidemic supervision and propose solutions protecting healthy for soldiers and people in malaria epidemic area.\r\n', u'Subjects and methods: A retrospective cross sectional study was carried out on two provinces Binh Phuoc and Dak Lak\r\n', u'Results: there was 4 main disease types were fever, tuberculosis, diarrhea and malaria. Malaria at investigated times still accounted high rate comparing with general fever rate. Malaria risk contained in people living or working in forest and mountain field; free emigrants; armed forces and border guard. These subjects needed to improve regularly protection from malaria. Communication of health education is one of important method to prevent and control malaria.\r\n', u'Conclusion: It is necessary to implement strong methods (such as providing insecticide treated bed nets, indoor residual spray) to prevent and control malaria. \r\n', u'
