Olfactomedin-4 (OLFM4, GW112, hGC-1) is a glycoprotein belonging to the olfactomedin family. The expression of OLFM4 is strong in the small intestine, colon and prostate, and moderate in the stomach and bone marrow. Previous studies have revealed that OLFM4 is closely associated with many digestive diseases. Up-regulation of OLFM4 has been detected in the Helicobacter pylori ( H. pylori )-infected gastric mucosa, inflammatory bowel disease tissue and gastrointestinal malignancies, including gastric cancer, colorectal cancer, pancreatic cancer and gallbladder cancer...

Symptomatic intestinal strictures develop in more than one third of patients with Crohn's disease (CD) within 10 years of disease onset. Strictures can be inflammatory, fibrotic or mixed and result in a significant decline in quality of life, frequently requiring surgery for palliation of symptoms. Patients under the age of 40 with perianal disease are more likely to suffer from disabling ileocolonic disease thus may have a greater risk for fibrostenotic strictures. Treatment options for fibrostenotic strictures are limited to endoscopic and surgical therapy...

The majority of malignant melanomas in the small intestine are metastases from primary cutaneous lesions, it can also develop as a primary mucosal tumor in the gastrointestinal tract. In this report, we present rare cases of primary small bowel melanoma and review the current literature. A 78-year-old male presented with abdominal pain and CT enterography identified a ileal mass. A 79-year-old female presented with signs and symptoms of partial small bowel obstruction. Abdominopelvic CT and small bowel series revealed a obstructing mass in the distal jejunum...

BACKGROUND: Arterial tumor embolism (ATE) is a rare but life-threating complication. PRESENTATION OF CASE: A 55-year-old man with acute lower-limb ischemia was referred to our hospital after endovascular intervention failed and underwent above-the-knee amputation for severe limb necrosis. On postoperative day 8, he developed small bowel necrosis and underwent resection. Histopathological examination of the resected bowel revealed that the submucosal arterial emboli were positive for the markers of squamous cells...

Sclerosing encapsulating peritonitis (SEP) is a whitish fibrous envelope that encapsulates intra-abdominal peritonealized organs. Although it pathophysiology is not well understood, several possible causes have been reported in the literature, including peritoneal dialysis, past abdominal surgeries, peritonitis, beta-blockers and peritoneal carcinomatosis (PC). Some idiopathic cases, with no apparent causes, were described. We present a SEP case in a 43-year-old woman with a surgical history of pancreatic and liver resection for metastatic pseudopapillary pancreatic tumor, followed by several peritonectomies for PC...

PURPOSE OF REVIEW: Therapeutic drug monitoring (TDM) has emerged as a useful tool to optimize the use of drug therapies in adults with inflammatory bowel disease (IBD), including both Crohn's disease (CD) and ulcerative colitis (UC), especially during the use of biological therapies, for which the pharmacokinetics and pharmacodynamics are highly variable among patients. Fewer data exist in children. This review examines the current literature on TDM in pediatric IBD. RECENT FINDINGS: Drug clearance is affected by a number of patient and disease factors...

The incidence of tonsillar cancer has increased by four times in the United States over the last few decades likely due to recent increase in human papilloma virus (HPV) infections. The stage of the tumor predicts likelihood of metastasis, with advanced stages associated with higher chances of metastasis. The squamous cell carcinomas (SCCs) of the head and neck commonly metastasize to the lung, bone and liver in descending order. Tonsillar cancer rarely involves the small bowel and our review of the literature did not reveal any reported case of metastasis to the colon/large bowel...

BACKGROUND/AIMS: A key issue in neuroendocrine neoplasia management is the identification of blood signatures that specifically define the activity of a cancer or local tumor microenvironment. MicroRNAs (miRNAs) may represent such a candidate. To evaluate their clinical utility as biomarkers in gastroenteropancreatic neuroendocrine tumors (GEP-NETs), we assessed their expression in tissue and blood. METHODS: A systematic review of PubMed was undertaken to identify studies investigating miRNAs in GEP-NETs and their utility as blood or tissue biomarkers...

The pharmacological management of inflammatory bowel disease (IBD) over the last two decades has transitioned from reliance on aminosalycilates, corticosteroids and immunomodulators to earlier treatment with anti-tumor necrosis factor (anti-TNF) therapy. Nevertheless, 20-30% of patients discontinue anti-TNF therapy for primary non-response and another 30-40% for losing response within one year of treatment. These undesirable therapeutic outcomes can be attributed to pharmacokinetic (anti-drug antibodies and/or low drug concentrations) or pharmacodynamic issues characterized by a non-TNF driven inflammation...

Inflammatory bowel disease (IBD) is a collection of inflammatory conditions of colon and small intestine which affect millions of individuals worldwide and the prevalence amount is on the rise. The organ failure as well as loss of tissue function is because of the inflammatory reaction which is the major contributor of tissue healing leading to lifelong debilitation. To stop the tough consequences of inflammation every patient pursues alternative therapy to relieve symptoms. Green tea polyphenols (GTPs) play significant roles in down regulating signaling pathways because GTPs exert effective antioxidant properties and regulate Toll-like receptor 4 (TLR4) expression via certain receptor, inhibited endotoxin-mediated tumor necrosis factor alpha (TNF-α) production by blocking transcription nuclear factor-kappa B (NF-kB) activation and upstream of mediated I kappa B kinase complex pathway activities, as well as intrusion with the flow of cytokines and synthesis of cyclooxygenase-2 (COX-2)...

Lynch syndrome is the most common hereditary cancer syndrome, the most common cause of heritable colorectal cancer, and the only known heritable cause of endometrial cancer. Other cancers associated with Lynch syndrome include cancers of the ovary, stomach, urothelial tract, and small bowel, and less frequently, cancers of the brain, biliary tract, pancreas, and prostate. The oncogenic tendency of Lynch syndrome stems from a set of genomic alterations of mismatch repair proteins. Defunct mismatch repair proteins cause unusually high instability of regions of the genome called microsatellites...

REVIEW

Intestinal malrotation is a continuum of congenital anomalies due to lack of rotation or incomplete rotation of the fetal intestine around the superior mesenteric artery axis. The abnormal bowel fixation (by mesenteric bands) or absence of fixation of portions of the bowel increases the risk of bowel obstruction, acute or chronic volvulus, and bowel necrosis. The clinical presentation of patients with malrotation without, with intermittent, or with chronic volvulus can be problematic, with an important minority presenting late or having atypical or chronic symptoms, such as intermittent vomiting, abdominal pain, duodenal obstruction, or failure to thrive...

BACKGROUND/AIM: Clear cell sarcoma-like tumor of the gastrointestinal tract (CCSLTGT) is a very rare and relatively recently characterized mesenchymal neoplasm arising within the wall of the small bowel, stomach, or large bowel, predominantly in adolescents and young adults. Only few anecdotal reports or small series have been published and a consensus on treatment has not been formulated. Complete resection remains the only curative option for localized disease, but despite optimal surgery, CCSLTGT typically shows highly aggressive behavior with a high rate of local recurrence, metastases, and death from disease...
