To investigate the prevalence and the significance of Helicobacter pylori duodenal colonization, endoscopic duodenal biopsies were performed in 168 children with chronic abdominal pain, gastroesophageal reflux, gastrointestinal bleeding, and malabsorption syndrome. Helicobacter pylori infection was detected in 68 children (40.4%): in 31 of them H. pylori was present in the gastric antrum, and in 37 in the duodenum also. Duodenitis was observed in 25 children with duodenal H. pylori; gastric metaplasia in 3. Scanning electron microscopy revealed the presence of the micro-organism in 3/13 cases; the bacteria were located in the intercellular spaces and alterations of the epithelial surface were found. In conclusion, H. pylori gastritis in children is often associated with duodenal colonization which can cause duodenitis, and also without gastric metaplasia, which indicates a possible role of the micro-organism in the pathogenesis of the lesions.

Typhlitis or neutropenic enterocolitis is a life-threatening, necrotizing process of the cecum whose incidence is increasing. It is usually encountered in patients with leukemia who have recently undergone chemotherapy. Neutropenic enterocolitis presents as fever, abdominal pain, and diarrhea in neutropenic patients. As the incidence of neutropenic enterocolitis increases, emergency physicians must be aware of this rapidly progressive and potentially fatal disease.

Colitis can cause significant morbidity in pediatric solid organ transplant recipients. In many cases, despite intensive evaluation, a specific infectious, inflammatory, or immunologic etiology is not identified, and idiopathic colitis may be the ultimate diagnosis. We defined idiopathic colitis as the presence of gastrointestinal symptoms (vomiting, diarrhea, abdominal pain) with inflammatory changes seen on intestinal biopsy in the absence of identifiable bowel disease. We describe three cases of idiopathic colitis following cardiac transplantation. In each case, the post-transplant course was complicated by persistent abdominal pain, diarrhea, and in two cases, vomiting. All three patients' post-transplant courses were marked by multiple graft rejection episodes, and all received intensified immune therapy in addition to usual maintenance immunosuppression. Differential diagnosis of the patients' gastrointestinal symptoms included drug side effect, indolent opportunistic infections, inflammatory bowel disease, post-transplant lymphoproliferative disease, and microvascular ischemic colitis. Continued symptoms led these patients to extensive evaluation including imaging studies, endoscopy and tissue biopsy, and stool, blood and tissue cultures for viral, bacterial and parasitic pathogens. Definitive differentiation presented significant diagnostic challenge, and once identifiable etiologies were excluded, the diagnosis of idiopathic colitis was assigned. We conclude that idiopathic colitis following pediatric cardiac transplantation can be a cause of significant morbidity. Endoscopic evaluation of patients who present with gastrointestinal symptoms after transplant is warranted to identify the presence of idiopathic colitis once common causes are ruled out. Further study is needed to identify its incidence, etiology, therapeutic options and prognosis.

Colitis amebiasis is usually characterized by bloody and mucous diarrhea, abdominal pain and anal discomfort. However, there is unusual manifestation of colitis amebiasis, such as occasional dripped anal bleeding, which sometimes spouted. Therefore, we often do not suspect such symptoms for colitis amebiasis. Laboratory examination includes complete laboratory test, coagulation and hematologic test, ICT TBC and colonoscopy. The pathology anatomy examination reveals positive results of trophozoites. Treatment by using metronidazole tablet provides good result for this disease.

Although Crohn's disease is thought to be rare and intestinal tuberculosis common in India, Crohn's disease is being reported more often. However, there is a lack of systematic study on Crohn's disease from India. In this analysis of data from three inflammatory bowel disease clinics (two in northern India and one in eastern India), criteria for Crohn's disease were applied retrospectively: (1) World Health Organization (WHO) criteria; or (2) compatible histology (European Crohn's and Colitis Organization) or failure of response to 4-8 weeks of anti-tuberculosis therapy (Asia-Pacific guidelines); or (3) compatible macroscopic, radiologic, colonoscopic features (European Crohn's and Colitis Organization). Others were classified as probable Crohn's disease. The Montreal classification was used for disease phenotype. Age at onset and duration of symptoms (182 patients, 117 male) were 34.5 (+/-13.6; 7-73) years and 3.0 (+/-5.8; 0.1-36) years, respectively. Diarrhea (68%), abdominal pain (62%), and weight loss (57%) were common. The common intestinal complications were occult (27%) and overt (40%) gastrointestinal bleeding and obstruction (28%). There were 141 (78%) and 41 (22%) with definite and probable Crohn's disease respectively. Of 147 (81%) available histopathology specimens (endoscopic biopsy in 110; 75%), 31 (21%) had granuloma. Seventy-one out of 166 (43%) had received anti-tuberculosis therapy in the past. Results from the Montreal classification were as follows: age at onset, A1:A2:A3 6%:64%:30%; location of disease, L1:L2:L3:L4 32%:41%:23%:4%, and disease behavior, B1:B2:B3 51%:24%:25%. Twenty-six (15%) and 31 (17%) patients had upper gastrointestinal and perianal modifiers. The drugs used were: aminosalicylates (128, 70%), steroids (76, 42%), azathioprine (53, 29%), methotrexate (4, 2%), and salazopyrine (14, 8%). Sixty-six (36%) patients underwent surgical treatment. We concluded that the phenotype of Crohn's disease in India is very similar to that described in other regions of Asia and the West, except for a delay in diagnosis and a more complicated disease at diagnosis.

Abdominal pain is a frequent complaint in patients with Systemic Lupus Erythematosus (SLE). The authors describe the case of a 33-year-old SLE female patient, followed in their rheumatology clinic, who presented with acute and diffuse abdominal pain, vomiting and diffuse rebound tenderness at abdominal examination. Abdominal ultrasound and CT scans showed small bowel wall thickening, with target sign on the CT scan, which suggested the diagnosis of Lupus Enteritis. The patient was treated with high-dose corticosteroids, with rapid resolution of all abdominal abnormalities. Lupus Enteritis is a rare complication of SLE, due to intestinal small-vessel vasculitis. It is a very serious complication of SLE, but the prognosis can be greatly improved with early diagnosis and adequate treatment, as in the case presented here.

Colitis can occur from viral or bacterial infections, ischemic insult, or autoimmune disorders; most notably Ulcerative Colitis and the colonic variant of Crohn's Disease - Crohn's Colitis. Acute colitis may present with abdominal pain and distention, malabsorption, diarrhea, hematochezia and mucus in the stool. We are beginning to understand the complex interactions between the environment, genetics, and epithelial barrier dysfunction in Inflammatory Bowel Disease and animal models of colitis have been essential in advancing our understanding of this disease. One popular model involves supplementing the drinking water of mice with low-molecular weight Dextran Sodium Sulfate (DSS), resulting in epithelial damage and a robust inflammatory response in the colon lasting several days.Variations of this approach can be used to model acute injury, acute injury followed by repair, and repeated cycles of DSS interspersed with recovery modeling chronic inflammatory diseases. After a single four-day treatment of 3% DSS in drinking water, mice show signs of acute colitis including weight loss, bloody stools, and diarrhea. Mice are euthanized at the conclusion of the treatment course and at necropsy dissected colons are processed and can be 'Swiss rolled" to allow microscopic analysis of the entire colon or infused with formalin as "sausages" to allow macroscopic analysis. Tissue is then embedded in paraffin, sectioned, and stained for histologic review.

Background. Cytomegalovirus (CMV) disease is rare in previously immunocompetent patients. We report a case of CMV enteritis complicated by massive intestinal bleeding. Case History. A 72-year-old immunocompetent patient was admitted for diarrhea and abdominal pain. Aspecific pattern of duodenitis was found at abdomen computed tomography and on biopsies during endoscopy. A diagnosis of vasculitis was suspected on the basis of the clinical and biological course (skin lesions, arthralgias, proteinuria, low complement C3 and C4 fractions, etc.) and pulse steroid therapy was prescribed. The patient developed multiple episodes of intestinal bleeding with shock and required urgent laparotomy. Jejunitis due to CMV vasculitis was proven by histological examination of the operative specimen. Treatment with ganciclovir was initiated. No bleeding recurrence was noted. No other lesions from CMV infection were observed. The patient died from unrelated complications. Discussion. CMV enteritis is a rare cause of intestinal bleeding particularly in previously immunocompetent patients. Aging could be accompanied by a relative immune weakness and specific antiviral therapy seems to be indicated.

Colitis in neutropenic patients presents with non-specific clinical findings including abdominal pain, fever, diarrhea and abnormal liver function tests. Four diagnoses are relatively more frequent: neutropenic enterocolitis, pseudomembranous colitis, intestinal GVHD and CMV colitis. Knowledge of their respective imaging features combined with epidemiological data frequently leads to the correct diagnosis. The purpose of this paper is to illustrate the imaging features of colitis in neutropenic patients.

The lead time between diagnosis of Crohn's disease and presentation with a Crohn's related malignancy is generally twenty years from diagnosis. This case outlines that of a young man who presented to the emergency department with abdominal pain and was subsequently discovered to have a malignant stricture complicating underlying Crohn's disease that was previously quiescent and undiagnosed. It demonstrates that a new diagnosis of Crohn's disease does not rule out previously quiescent underlying disease and therefore risk of colrectal carcinoma.
