| 1 | Unusual presentations of eosinophilic gastroenteritis:Case series and review of literature显示文摘Eosinophilic gastroenteritis (EG) is an uncommon disease characterized by focal or diffuse eosinophilic infiltration of the gastrointestinal tract, and is usually associated with dyspepsia, diarrhea and peripheral eosinophilia. Diffuse gastrointestinal tract and colonic involvement are uncommon. The endoscopic appearance may vary from normal to mucosal nodularity and ulceration. Gastrointestinal obstruction is unusual and is associated with predominantly muscular disease. We present five unusual cases of EG associated with gastric outlet and duodenal obstruction. Two cases presented with acute pancreatitis and one had a history of pancreatitis. Four cases responded well to medical therapy and one had recurrent gastric outlet obstruction that required surgery. Four out of the five cases had endoscopic and histological evidence of esophagitis and two had colitis. Two patients had ascites. These cases reaffirm that EG is a disorder with protean manifestations and may involve the entire gastrointestinal tract. Gastric outlet and/or small bowel obstruction is an important though uncommon presentation of EG. It may also present as esophagitis, gastritis with polypoid lesions, ulcers or erosions, colitis and pancreatitis and may mimic malignancy. | Rafiq A Sheikh Thomas P Prindiville R Erick Pecha Boris H Ruebner | 2009 | World Journal of Gastroenterology2009，15，17： | 43 |
| 2 | Increased expression of tumor necrosis factor-a is associated with advanced colorectal cancer stages显示文摘AIM:To detect the expression of tumor necrosis factor-a(TNF-a)in colorectal cancer(CRC)cells among Saudi patients,and correlate its expression with clinical stages of cancer.METHODS:Archival tissue specimens were collected from 30 patients with CRC who had undergone surgical intervention at King Khalid University Hospital.Patient demographic information,including age and gender,tumor sites,and histological type of CRC,was recorded.To measure TNF-a m RNA expression in CRC,total RNA was extracted from tumor formalin-fixed,paraffinembedded,and adjacent normal tissues.Reverse transcription and reverse transcription polymerase chain reaction were performed.Colorectal tissue microarrays were constructed to investigate the protein expression of TNF-a by immunohistochemistry.RESULTS:The relative expression of TNF-a m RNA in colorectal cancer was significantly higher than that seen in adjacent normal colorectal tissue.High TNF-a gene expression was associated with StageⅢandⅣneoplasms when compared with earlier tumor stages(P=0.004).Eighty-three percent of patients(25/30)showed strong TNF-a positive staining,while only 10%(n=3/30)of patients showed weak staining,and 7%(n=2/30)were negative.We showed the presence of elevated TNF-a gene expression in cancer cells,which strongly correlated with advanced stages of tumor.CONCLUSION:High levels of TNF-a expression could be an independent diagnostic indicator of colorectal cancer,and targeting TNF-a might be a promising prognostic tool by assessment of the clinical stages of CRC. | Omar A Al Obeed Khayal A Alkhayal Abdulmalik Al Sheikh Ahmad M Zubaidi Mansoor-Ali Vaali-Mohammed Robin Boushey James H Mckerrow Maha-Hamadien Abdulla | 2014 | World Journal of Gastroenterology2014，20，48： | 8 |
