CONTEXT Chronic pancreatitis is common in India. However, its risk factors are not clear. There is sparse data on the current prevalence of tropical pancreatitis in India. OBJECTIVE To undertake a prospective nationwide study of the risk factors and clinical profile of chronic pancreatitis. SETTING Thirty-two major centers from different regions of(More)
AIMS To study the profile of irritable bowel syndrome (IBS), and the frequency of such symptoms among the general population, in India. METHODS In this prospective, multi-center study, data were obtained from 2785 patients with chronic lower gastrointestinal symptoms (complainants) with no alarm feature and negative investigations for organic causes(More)
Thirty-nine patients with cholelithiasis were prospectively studied to evaluate the qualitative and quantitative differences between duodenal bile and gallbladder bile. Duodenal bile obtained before cholecystectomy by nasoduodenal intubation and ceruletide injection was qualitatively similar to gallbladder bile obtained during surgery. Microscopic(More)
Chronic pancreatitis is a persistent inflammatory disease of the pancreas, in which the digestive protease trypsin has a fundamental pathogenetic role. Here we have analyzed the gene encoding the trypsin-degrading enzyme chymotrypsin C (CTRC) in German subjects with idiopathic or hereditary chronic pancreatitis. Two alterations in this gene, p.R254W and(More)
The association of polymorphism in cytochrome P450 2E1 (CYP2E1), the major microsomal ethanol metabolizing enzyme and its interaction with genes, involved in detoxification of reactive oxygen species, such as glutathione-S-transferases M1 (GSTM1) and alcohol intake, gamma-aminobutyric acid receptor gamma2 (GABRG2) was studied with the risk to alcoholic(More)
OBJECTIVES Genetic mutations and polymorphisms have been correlated with chronic pancreatitis (CP). This study aims to investigate the association of genetic variants of cystic fibrosis transmembrane conductance regulator (CFTR) and serine protease inhibitor Kazal type 1 (SPINK-1) genes and Cathepsin B gene polymorphisms with CP and to associate genetic(More)
BACKGROUND & AIMS Tropical calcific pancreatitis (TCP) is a chronic pancreatitis unique to developing countries in tropical regions. The cause of TCP is obscure. Whereas environmental factors, such as protein energy malnutrition and ingestion of cassava, have been implicated, a genetic predisposition to the disease also may be important. In the present(More)
BACKGROUND AND AIM Gallbladder carcinoma (GBC) usually arises in the background of gallstone disease which may be causatively related to decreased gallbladder contractility. Cholecystokinin receptor A (CCK-AR) mediates signals resulting in gallbladder contraction. Deteriorating gallbladder contraction promotes gallstone formation. A common genetic(More)
Rectal endoscopic ultrasonography was performed using an ultrasound fiberscope in 20 patients with cirrhotic portal hypertension (6 alcoholic patients, 4 patients with hepatitis B surface antigen positive, and 10 cryptogenic patients) and in 10 patients with irritable bowel syndrome as controls. Rectal varices were diagnosed endoscopically when either(More)
The high failure rate of contact litholytic therapy for common bile duct stones with currently available cholesterol solvents has been attributed to the inclusion of patients with pigment stones, as no pretreatment investigation is undertaken to distinguish the two stone types. In 36 patients with common bile duct stones we prospectively evaluated the(More)
