Endoscopic ultrasonography (EUS), one of the imaging diagnosis technique used in many countries in the world, has been first applied in Vietnam recently. This method has high value in diagnosis of the upper gastrointestinal tract, particularly of pancreatic diseases. We used EUS with sector scan transducer in 30 patients. Who were suspected to have pancreatic tumors. Result of surgery and histopathological examination of 22 patients (who accepted to have operation) are considered as the gold standard for determining the accuracy of EUS. 30 patients was 15 to 90 years old, mean age: 57.2 Male: 21/30 -70%, female: 9/30 = 30%. The results following: the accuracy of EUS is 19/22 cases (about 85%), the majority of pancreatic tumors was located in the head 14/19 (about 74%), smallest tumor is 1.4-1.5cm, invasion in to duodenum, portal vein, and lymph nodes in some cases.

Introduction: Hepatitis C is a dangerous disease and if left untreated can have serious consequences to the patients. While hepatitis C is difficult to treat, its vaccine is still unavailable. Previous studies have showed that there is a low rate of drug users having HCV tests. This means HCV infections does not have any great importance attached to it amongst the drug user group.\r\n', u'Objectives: To discover the status of HCV infection among drug users in Hanoi and to analyse the associated factors. \r\n', u'Subjects and methods: This crossover descriptive study was conducted in Hanoi. Research objects consisted of only men within the 16 - 25 years old age group, who used heroin from 09/2005 to 12/2006. These participants were interviewed and tested for HIV, HCV and HBV.\r\n', u'Results: HCV prevalence is 35.1 %. Especially, the research has indicated that 100% of HIV infected cases have also contracted HCV. This co - infectious status can be a challenge to subjects when they experience ARV treatment. The mean age of surveyed participants is 19. 83.6% of them have attended secondary school. 30.1 % have taken part in illegal earning activities. \r\n', u'Conclusion: HCV infection was discovered in the early drug injection stage. The proportion of HIV infection among injecting drug users is 28.24 times compared to the smoking drug users.\r\n', u'
