BACKGROUND AND OBJECTIVES: In Crohn's disease (CD), belonging to inflammatory bowel disease, the small intestine is involved in most cases. Most frequently affected is the distal ileum, where vitamin B-12 is specifically absorbed. Therefore, malabsorption of vitamin B-12 is quite likely to occur in patients with CD. In this study, we have studied the vitamin B-12 status in CD patients. METHODS AND STUDY DESIGN: Forty eight patients with CD were evaluated for their food intake, and circulating concentrations of vitamin B-12, folic acid, and homocysteine (Hcy) as a sensitive marker for the insufficiency of these vitamins and a risk factor of atherosclerosis...

Diabetes mellitus (DM) and its associated complications are becoming increasingly prevalent. Gastrointestinal symptoms associated with diabetes is known as diabetic enteropathy (DE) and may manifest as either diarrhea, fecal incontinence, constipation, dyspepsia, nausea, and vomiting or a combination of symptoms. The long-held belief that vagal autonomic neuropathy is the primary cause of DE has recently been challenged by newer theories of disease development. Specifically, hyperglycemia and the resulting oxidative stress on neural networks, including the nitrergic neurons and interstitial cells of Cajal (ICC), are now believed to play a central role in the development of DE...

BACKGROUND: Neuroendocrine tumors (NETs) are heterogeneous neoplasms that originate from cells with a secretory function. Small bowel NETs (SB-NETs) are related to serotonin hypersecretion which causes: flushing, diarrhea, abdominal pain, bronchoconstriction and heart involvement, also known as carcinoid syndrome (CS). CS can be confused with an allergic reaction and thus should be considered as a differential diagnosis in the allergy consult. We present the case of a pediatric patient initially referred under the suspicion of food allergies...

BACKGROUND: Methionine, a central molecule in one-carbon metabolism, is an essential amino acid required for normal growth and development. Despite its importance to biological systems, methionine is toxic when administered at supra-physiological levels. The aim of this study was to investigate the effects of short-term methionine dietary modulation on the proximal jejunum, the section of the gut specifically responsible for amino acid absorption, in a mouse model. Eight-week-old CBA/J male mice were fed methionine-adequate (MAD; 6...

OBJECTIVES: Many patients with small bowel neuroendocrine tumors (SBNETs) have multifocal tumors (MFTs), but the frequency of MFTs has varied widely across SBNET studies. It is also unclear whether patients with MFTs have more advanced disease or worse clinical course than do those with unifocal SBNETs. We set out to determine the frequency of multifocal and unifocal SBNETs and compare clinicopathologic factors, somatostatin receptor 2 expression, and survival. METHODS: Clinicopathologic variables from 179 patients with surgically managed SBNETs were collected...

Digestive graft versus host disease (GVHD) is a frequent complication after bone marrow transplantation (BMT), but small bowel obstruction is an extremely rare event. We present herein the first pediatric series of 4 cases of small bowel obstruction after BMT with detailed gross, histological data and their genetic status of the NOD2 gene. All patients had a history of severe acute GVHD treated by immunosuppressive agents and/or infliximab (in 3 cases). Acute or progressively worsening abdominal pain accompanied by small bowel occlusion occurred 5-16months after graft and CT-scan revealed multiple small intestinal stenosis...

BACKGROUND: Pancreatoduodenectomy is a surgical procedure used to treat diseases of the pancreatic head and, less often, the duodenum. The most common disease treated is cancer, but pancreatoduodenectomy is also used for people with traumatic lesions and chronic pancreatitis. Following pancreatoduodenectomy, the pancreatic stump must be connected with the small bowel where pancreatic juice can play its role in food digestion. Pancreatojejunostomy (PJ) and pancreatogastrostomy (PG) are surgical procedures commonly used to reconstruct the pancreatic stump after pancreatoduodenectomy...

Idiopathic myointimal hyperplasia of the mesenteric veins (IMHMV) is a rare disease characterized by intimal smooth muscle proliferation, leading to the thickening of small to medium-sized mesenteric veins. This vascular disease mimics inflammatory bowel disease (IBD) clinically and endoscopically, while showing ischemic mucosal changes without the classic features of IBD on biopsy. Given the mixed picture, this entity is frequently misdiagnosed. Surgical resection of the diseased bowel segment reveals the true etiology of the pathology and is curative...

Crohn's disease (CD) is a common chronic inflammatory disease of the small and large intestines. Murine and human mesenchymal stem cells (MSCs) have immunosuppressive potential and have been shown to suppress inflammation in mouse models of intestinal inflammation, even though the route of administration can limit their homing and effectiveness (1)(,)(3)(,)(4)(,)(5). Local application of MSCs to colonic injury models has shown greater efficacy at ameliorating inflammation in the colon. However, there is paucity of data on techniques to enhance the localization of human bone marrow-derived MSCs (hMSCs) to the small intestine, the site of inflammation in the SAMP-1/YitFc (SAMP) model of experimental Crohn's disease...

Neoplasms of the small bowel are rare and comprise only 1-5% of all gastrointestinal neoplasms. The most frequent malignant tumors located in the small bowel are adenocarcinomas, lymphomas and neuroendocrine tumors. Rarely observed are gastrointestinal stromal tumors (GIST), leiomyosarcomas and leiomyomas. Leiomyomas are most frequently seen in the jejunum followed by the ileum and lastly the duodenum. In most cases, a definite diagnosis of these tumors is not possible prior to surgical treatment. The treatment of choice for these tumors is surgery...

Cathelicidin peptide LL-37 plays an important role in the early host response against invading pathogens via its broad-spectrum antimicrobial activity. In this study, we investigated LL-37 expression in the inflamed mucosa of IBD patients. Furthermore, the regulatory mechanism of LL-37 induction was investigated in human colonic subepithelial myofibroblasts (SEMFs). LL-37 mRNA expression and protein secretion were analyzed using real-time polymerase chain reaction and enzyme-linked immunosorbent assay, respectively...

INTRODUCTION: The immune microenvironment is a prognostic factor for various malignancies. The significance of key players of this immune microenvironment including tumor-infiltrating lymphocytes and expression of programmed death-ligand 1 (PD-L1), indoleamine-2,3-dioxygenase (IDO), and tryptophanyl-tRNA synthetase (WARS) in gastrointestinal stromal tumors (GISTs) is largely unknown. METHODS: Tissue microarrays were constructed from pathology files, 1996-2016. Immunohistochemistry for PD-L1, IDO, WARS was correlated with tumor size, mitoses, and outcomes...

Small mothers against decapentaplegic (SMAD) proteins are a family of signal transduction molecules in transforming growth factor β (TGFβ) ligand pathways that have been found to have a key role in the pathogenesis of inflammatory bowel disease (IBD). Long standing IBD predisposes individuals to colitis-associated colorectal cancer (CAC), an entity that possess unique characteristics compared to hereditary and sporadic cancer. The ligands of the TGFβ super family along with SMADs have also been implicated in several aspects of colorectal cancer formation...
