| 3 | Enterolithiasis complicating eosinophilic enteritis:A case report and review of literature显示文摘We report a case of eosinophilic enteritis involving the proximal small bowel,a relatively rare entity,presenting unusually as enteroliths in a 68-year-old man with complaints of anemia,malena and abdominal pain.The disease if diagnosed in the initial stages responds well to medical treatment but if associated with complications or misdiagnosed,surgical modality is the treatment of choice.In our case,the patient presented with enteroliths and strictures.Resection and anastomosis of the small bowel containing stones was carried out.Histopathology conf irmed the diagnosis as eosinophilic enteritis. | Nairuthya Shivathirthan Gaurav Maheshwari Dinesh Kamath Premashish Haldar | 2009 | World Journal of Gastrointestinal Surgery2009，1，1： | 0 |
| 4 | Role of CYP2E1 gene polymorphisms association with hepatitis risk in Northeast India显示文摘AIM:To investigate hepatitis virus, genetic and environmental factors, and their interactions in predisposing patients to liver diseases in Northeast India. METHODS:A total of 104 jaundice patients and 124 community controls were included. Serological analysis was performed by routine enzyme-linked immunosorbent assay, and nucleic acid testing for hepatitis viruses was done by polymerase chain reaction (PCR), followed by PCR direct sequencing for viral genotyping. Cytochrome P450 2E1 (CYP2E1) polymorphism was studied by PCR-restriction fragment length polymorphism. Nitrite and volatile nitrosamines in indigenous foods consumed routinely by the Northeast Indian ethnic population were estimated by Griess’s reagent and GC-MS, respectively.RESULTS: Hepatitis A virus (HAV) infection was predominantly prevalent (36.5%) in our cohort, followed by hepatitis B virus (HBV), hepatitis E virus (HEV) andhepatitis C virus. HBV genotype D and HEV genotype 1 were the most dominant. CYP2E1 c1/c2 genotype frequency was comparatively higher in alcoholic (P<0.0001,OR =30.5) and cryptogenic (P=0.014, OR=8.714) patients, and was associated with significantly higher hepatitis risk (P=0.0.007,OR=6.489). Mutant C allele of Cyp2E1 DraⅠ frequency was comparatively higher in HAV (P=0.006), alcoholic (P =0.003) and cryptogenic (P=0.014) cases, and was associated with overall hepatitis risk (P=0.026, OR=5.083). Indigenous foods, Gundruk, Kharoli, betel leaf and nuts were found to have the highest nitrite content. CONCLUSION: Apart from viral factors, CYP2E1 polymorphism might be associated with increased risk of liver diseases in Northeast India. Indigenous foods that contain nitrite and nitrosamine might be an associated risk factor. | Manab Deka Moumita Bose Bharati Baruah Purabi Deka Bose Subhash Medhi Sujoy Bose Anjan Saikia Premashish Kar Subhash Medhi Sujoy Bose | 2010 | World Journal of Gastroenterology2010，16，38： | 0 |
