Study reaction of pancreas in 35 patients (14 males, 21 females, mean age: 49.12) underwent endoscopic retrograde cholangiopancreatogaphy with and without sphinterotomy at Bach Mai Hospital from February 2007 to February 2008. The result showed that: f pure serum amylase increased immediately in 77.14 % patients by fourth hour after surgery. Increasing in pure serum amylase returned by 96 hours after procedure without treatment. Increasing in pure serum amylase depended on some factors as contrast enhanced agents, sphinterotomy or not. Acute pancreatitis was a complication after endoscopic retrograde cholangiopancreatogaphy

Objective: The purpose of this survey was to estimate the prevalence of viral load (VL) suppression and emergence of HIV drug resistance (HIVDR) among individuals receiving antiretroviral therapy (ART) for 36 months or longer in Viet Nam using a nationally representative sampling method. Methods: The survey was conducted between May and August 2014 using a two-stage cluster design. Sixteen ART clinics were selected using probability proportional to proxy size sampling, and patients receiving ART for at least 36 months were consecutively enrolled. Epidemiological information and blood specimens were collected for HIV-1 VL and HIVDR testing; HIVDR was defined by the Stanford University HIVDR algorithm. Results: Overall, 365 eligible individuals were recruited with a mean age of 38.2 years; 68.4% were men. The mean time on ART was 75.5 months (95% confidence interval [CI]: 69.0–81.9 months), and 93.7% of the patients were receiving non-nucleoside reverse transcriptase inhibitor-based regimens. Of the 365 individuals, 345 (94.7%, 95% CI: 64.1–99.4%) had VL below 1000 copies/mL and 19 (4.6%, 95% CI: 2.8-–7.5) had HIVDR mutations. Discussion Our nationally representative survey found a high level of VL suppression and a low prevalence of HIVDR among individuals who received ART for at least 36 months in Viet Nam. Continued surveillance for HIVDR is important for evaluating and improving HIV programs.
