Since Aird, Bentall, Mehigan, and Roberts (1954) convincingly demonstrated a high incidence of blood group 0 in duodenal ulcer subjects there have been a number of confirmatory studies carried out in different ethnic groups and populations (McConnell, 1966). Studies have also been undertaken to see if there is an especially strong association between blood group 0 and some particular category o...

Anorectal Malformations are known to be associated with various other congenital anomalies including duodenal atresia. An association of congenital intrinsic duodenal obstruction causing partial duodenal obstruction in a patient with anorectal malformation is not described in literature. We describe a case of delayed presentation of congenital intrinsic duodenal obstruction in a child with high...

The proximal duodenal mucosa secretes HCO that serves to protect the epithelium from injury. In isolated human duodenal enterocytes in vitro, multiple luminal membrane proteins are involved in acid/base transport. We postulated that one or more isoforms of the Na(+)/H(+) exchanger (NHE) family is located on the apical surface of human duodenal mucosal epithelial cells and thereby contributes to...

purpose: to compare the prevalence of glaucoma among peptic ulcer patients with or without helicobacter pylori infection. methods: among 352 patients with an indication of gasterointestinal endoscopy for peptic problems, 120 patients in 18-88 years of age were included for evaluation of glaucoma. according to the results of histopathologic and urease test, they were divided into two groups: hel...

BACKGROUND Allergy and functional gastrointestinal disorders have been associated with eosinophilia in duodenal mucosa. AIM To assess the prevalence of eosinophilia in duodenal biopsies of patients attending for oesophogastroduodenoscopy and delineate associated clinical conditions. METHODS A total of 155 patients (mean age 55 years, 59% women) with normal duodenal biopsies were randomly se...

BACKGROUND Duodenal cancer is one of the leading causes of death in familial adenomatous polyposis (FAP) patients. An endoscopic surveillance programme was therefore initiated in 1988, the outcome of which is described in this paper. METHODS We report the 10 year follow up of 114 patients with FAP who were prospectively screened for the presence and severity of duodenal adenomas. RESULTS Si...

The aim of this study was to examine the influence of cholecystokinin (CCK)-octapeptide (OP) and its amphibian analogue cerulein infusions on duodenal myoelectric and motor activities, as well as to compare the effects of CCK peptides on duodenal bulb and duodenal motility in non-fasted conscious rams. Five rams underwent implantation of bipolar platinum electrodes to the duodenal bulb, and dis...

BACKGROUND Coeliac disease is characterised by villous atrophy, which usually normalises after gluten withdrawal. Sometimes the revaluation of duodenal histology is required during follow-up, even if the methodology for comparing duodenal histology before and after introducing a gluten-free diet is not yet established. Our aim was to evaluate a novel criterion to compare duodenal histology in c...

Some 80-90% of gastrinomas are located in the gastrinoma triangle, which includes the duodenum, the pancreatic head, and the hepatoduodenal ligament. The natural history of the tumors depends on their origin. Duodenal gastrinomas are much less aggressive than pancreatic primaries and infrequently develop liver metastases. The reason therefore is unclear. The transcription factor pancreatic-duod...
