We report a case of gastroenteritis due to Yersinia enterocolitica in a 7month old male infant who was misdiagnosed as shigellosis at onset of illness. He was treated with Gentamicin successfully. A marked improvement was resulted in clinical symptoms and laboratory finding at the time of discharge. It is a second case of Y.enterocolitica which is proved by stool culture in Korea.

Nowadays, inflammatory bowel disease, such as ulcerative colitis and Crohn's disease, is increasing; however, infectious colitis, such as amebic colitis, is decreasing, so many doctors are not apt to be interested in infectious colitis. In addition, recently amebic colitis has been relatively rare in Korea, and the colonoscopic and the pathologic findings of amebic colitis are very similar to those of other inflammatory bowel diseases. As a consequence, the diagnosis is very difficult if the cyst or the trophozoite of the ameba is not found in the stool examination or in the tissue pathology. The authors experienced three cases in which initial diagnoses of tuberculous colitis, ulcerative colitis, and a simple ulcer were made based on colonoscopic and X-ray findings. However a colonoscopic biopsy revealed a trophozoite form of ameba in the tissue. Hence, a diagnosis of amebic colitis could be made with confidence. Based on these results, we insist that infectious colitis should be included in the differential diagnosis when making a diagnosis of inflammatory bowel disease. In addition, it is extremely important to consider all kinds of infectious colitis, such as amebic colitis.

Eosinophilic gastroenteritis is an uncommon disease characterized by eosinophilic infiltration in the bowel wall and presents various symptoms depending on the affected site and bowel layer. Pseudomembranous colitis is an antibiotic-associated infection caused by abnormal overgrowth of the toxin-producing Clostridium difficile in the large bowel. A 16-year-old boy was admitted with abdominal pain for 6 days. On admission, we performed an endoscopy and diagnosed gastroduodenitis. Then, we prescribed gastritis medication but he still presented with diffuse abdominal pain and fever above 38.0degrees C after admission. We considered infectious enterocolitis, so we prescribed an antibiotic. The next day, he presented with bloody diarrhea. A diagnosis of pseudomembranous colitis was confirmed by a colonoscopic examination with a biopsy. We also obtained a diagnosis of eosinophilic gastroenteritis through a histological diagnosis. This is the first case of the simultaneous occurrence of eosinophilic gastroenteritis and pseudomembranous colitis in the Korean medical literature. We report this case with a brief review of the literature.

BACKGROUND/AIMS: Ulcerative colitis is an inflammatory bowel disease with unknown etiology, which has waxed and waned course. It is diagnosed by colon study, pathology, and especially colonoscopy. It is difficult to differentiate between ulcerative colitis and other infectious colitis, especially amebic colitis, and to confirm of remnant lesion by endoscopic findings. METHODS: Magnifying colonoscopy has 100 time magnifying power compared to 30 time of conventional colonoscopy. By spraying 0.2% indigo carmine dye, we evaluated the magnifying and microscopic findings of 31 colonic mucosa of 23 patients with ulcerative colitis. RESULTS: Initial and magnifying chromoscopic findings in ulcerative colitis were loss of cryptal opening 72% (13/18), loss of submucosal vessel 89% (16/18), mucosal denudation (or microscopic erosion) 83% (15/18), and mucosal unevenness 94% (17/18). Recovery rate of magnifying chromoscopic findings after treatment in ulcerative colitis were in crytal opening 80% (8/10), submucosal vascularity 60% (6/10), mucosal denudation (microscopic erosion) 30% (3/10), and in mucosal unevenness 40% (4/10). CONCLUSIONS: It is suggested that magnifying chromoscopic findings in ulcerative colitis may be useful in initial diagnosis and confirmation of remnant lesion, but, not in prediction of clinical severity.

PURPOSE: The aim of this study is to determine the involvement of the upper gastrointestinal system (GIS) in patients diagnosed with Crohn's disease (CD), ulcerative colitis (UC), and non-inflammatory bowel disease (IBD) and to compare their differences. METHODS: This study included patients aged between 2 and 18 years who underwent colonoscopy and esophagogastroduodenoscopy (EGD) for the first time due to the prediagnosis of IBD. In EGD, samples were taken from duodenum, antrum, corpus, and esophagus; and gastritis, duodenitis, and esophagitis were identified through histopathologic examination. The data gathered the ends of the research were compared between IBD with non-IBD groups and between CD-UC with non-IBD groups, and the presence of significant differences between groups were determined. RESULTS: In our study, 16 patients were diagnosed with CD, 13 with UC, 3 with undeterminate colitis, and 13 with non-IBD. In the histopathological examination of the groups, GIS involvement was found in 94.1% of patients diagnosed with IBD and in 38.5% of non-IBD patients. Moreover, the difference was found to be statistically significant (p=0.032). No significant difference was found between the CD and UC groups. Gastritis was mostly observed in 93.8% of CD-diagnosed patients, 76.8% of UC-diagnosed patients, 81.2% of IBD-diagnosed patients, and 38.5% of non-IBD-diagnosed patients. On the other hand, significant differences were found between CD and non-IBD groups (p=0.03), UC and non-IBD groups (p=0.047), and IBD and non-IBD groups (p=0.03). CONCLUSION: The results of the study show that gastritis was highly observed in UC- and CD-diagnosed patients than in non-IBD-diagnosed patients.

Background: Eosinophilic gastroenteritis (EG) can mimic symptoms of common gastrointestinal (GI) disorders but responds well to appropriate treatment. Accurate diagnosis is central to effective management. Data on EG in Southeast Asia is lacking. We aim to describe the clinical profiles and treatment outcomes of adult patients with EG in a Singapore Tertiary Hospital. Materials and Methods: This retrospective study involved archival search of patients with GI biopsies that showed eosinophilic infiltration from January 2004 to December 2012. Patients’ clinical data from computerised hospital records and clinical notes was reviewed. Diagnostic criteria for EG included presence of GI symptoms with more than 30 eosinophils/high power field on GI biopsies. Patients with secondary causes for eosinophilia were excluded. Results: Eighteen patients with EG were identified (mean age 52 years; male/female: 11/7). Fifteen patients (83%) had peripheral blood eosinophilia. Seven patients (39%) had atopic conditions. Most common symptoms were diarrhoea and abdominal pain. Small intestine was the most common site involved. Endoscopic finding was non-specific. Ten patients were treated with corticosteroids (nine prednisolone, one budesonide): eight patients (89%) responded clinically to prednisolone but four patients (50%) relapsed following tapering-off of prednisolone and required maintenance dose. One patient each responded to diet elimination and montelukast respectively. Half of the remaining six patients who were treated with proton-pump inhibitors, antispasmodic or antidiarrheal agents still remained symptomatic. Conclusion: Prednisolone is an effective treatment though relapses are common. Small intestine is most commonly involved. EG should be considered in the evaluation of unexplained chronic recurrent GI symptoms.

Eosinophilic esophagitis, as a new emerging disease during the last decade, is a clinicopathologic disorder of the esophagus, and it is characterized by dense esophageal eosinophilic infiltrations and typical esophageal symptoms. These patients usually present with dysphagia, food impaction or refractory reflux symptoms, and biopsy of the esophagus shows more than 15 eosinophils per high-power field. The typical findings on endoscopy are linear furrows, ringed esophagus, mucosal nodularities, whitish plaques and/or stricture. It is essential to exclude the known causes of tissue eosinophilia such as gastroesophageal reflux disease, eosinophilic gastroenteritis, infections, drug, hypersensitivity, Crohn's disease or malignancy. The majority of these patients have an atopy or allergic disorders, so other causes of eosinphilia should be evaluated. The therapeutic options include acid suppression, steroids, dietary modification, endoscopic dilatation, etc. Eosinophilic esopahgitis has recently been reported in Korea. Future schematic studies about this new disease are needed.

Amebic colitis is a disease revealing diverse clinical manifestations and endoscopic gross features and often confused with other types of colitis. In case of misdiagnosis as an idiopathic inflammatory bowel disease or delayed recognition of intestinal amebiasis, an undesirable outcome may occur resulting from erroneous administration of steroids or delayed antiamebic treatment. To demonstrate the pitfalls in the diagnosis and treatment of intestinal amebiasis, 3 cases of amebic colitis with atypical clinical manifestations are presented in this paper. In conclusion, despite the low sensitivities of routine stool examination for parasite and histopathologic confirmation in biopsy specimen, every effort must be made to find amebic trophozoites either in fresh stool or biopsy specimens for prompt and correct diagnosis of amebic colitis when we manage patients with chronic intestinal ulcerations, even though their clinical course and endoscopic findings are not typical of amebiasis. Moreover, following initial successful anti-amebic therapy, more careful clinical, endoscopical, and parasitological follow-up should be done for the early detection of recurrence.
