To assess the stability of various sample types and storage conditions for quantitative detectability of hepatitis C virus (HCV) RNA viral loads, we studied serum and EDTA/citrate plasma samples obtained from 10 patients known to be positive for HCV RNA. Samples were subjected to the following conditions: 1) 10 freeze-thaw (FT) cycles, and 2) storage at room temperature for 24, 48, and 72 h. Detection of HCV RNA was performed by COBAS AmpliPrep/COBAS TaqMan HCV. The following conclusions were reached: 1) no significantly different viral loads were observed in different blood compartments; 2) no significantly different viral loads we . . .re observed after 24, 48, and 72 h at room temperature; 3) no significantly different viral loads were observed after 10 FT cycles in serum and plasma samples; and 4) HCV RNA is quite stable in serum and plasma (EDTA/citrate) samples. © 2013 Elsevier Inc.

Background: Ectopic biliary drainage is a rare congenital anomaly on which we have scarce data in the current literature.Methods: The data were collected from the records of 400 endoscopic retrograde cholangio-pancreatography (ERCP). In this report, we present 10 cases (male/female: 9/1, mean age 54 years, range 38-74) with ectopic biliary openings into the duodenum and/or stomach diagnosed by endoscopic retrograde cholangio-pancreatography (ERCP).Results: In our series, the frequency of ectopic biliary drainage is 2% (10 out of 400 ERCPs). Recurrent attacks of cholangitis and complicated ulcer formation in the distal stomach and bu . . .lbar duodenum were the most common signs in the present series. The sites of ectopic biliary drainage were the stomach in 1 case, the duodenum bulbus in 7 cases and the postbulbar duodenum in 2 cases. Bulbar ulcer, deformed pylorus and bulbus were present in 7 cases, apical bulbar stricture in 2, gastric ulcer in 1, pyloroplasty and/or gastroenterostomy in 3 cases. One case had had previous bleeding episode. Some of them had undergone previous surgeries for gall-stone disease (cholecystectomy in 5 cases, bile duct operation in 3 cases) and ulcer complications (pyloroplasty/gastroenterostomy in 3 cases). ERCP revealed dilatation of the biliary tree and hook shaped distal choledochus in all cases, choledocholithiasis in 7 and Mirizzi syndrome in 1. Endoscopic balloon dilatations for gastric outlet obstruction, extraction of bile stones after balloon dilating the ectopic site, surgery for difficult cases with large bile duct stones or with gastric outlet obstruction were preferred methods in this series of patients.Conclusion: With this report, we have to remind that ectopic biliary drainage must be considered in the differential diagnosis when the clinician faces cases with gastric outlet obstruction due to peptic ulcer formation accompanied by cholangitis/cholestasis. © 2010 Saritas et al; licensee BioMed Central Ltd Daha fazlası Daha az

Cavernous hemangiomas with shunt formations have been a recently recognized entity. Arterioportal (AP) shunts with cavernous hemangiomas have been described. However, a combination of AP and porto-systemic (PS) shunts causing portal hypertension has not been previously demonstrated by computed tomography (CT) imaging. In this study, we report an atypical cavernous hemangioma associated with portal hypertension. Cavernous hemangioma with AP and PS shunts formations was precisely demonstrated with dynamic multi-detector CT imaging. © Springer Science+Business Media, LLC 2009.
