The enteric nervous system (ENS) is the division of the autonomic nervous system that innervates the gastrointestinal (GI) tract and controls central intestinal functions such as peristalsis and fluid movement. Enteric nerve cell bodies (neurons and glia) are predominantly organized in ganglionated networks that are present along the entire length of the GI tract in multiple tissue layers. Most cell bodies are organized in the myenteric plexus allocated between the longitudinal and the circular muscle layers or in the submucosal plexus between muscle tissue and mucosa...

BACKGROUND: Despite their low occurrence, endoscopic perforations (EPs) are concerning. Some predictive factors have been identified, and EP management is debated, whether non-surgical (medical and/or endoscopic) or surgical. The objective was to elaborate a predictive score for surgical management of EP. METHODS: All the patients addressed for upper and lower EP, except oesophageal EP, were retrospectively included (2004-2015). Demographic data, endoscopic features (indication, location, type), clinical, biological and radiological presentations of EP were reviewed...

There are several drug products that bind phosphate or bile acid in the gastrointestinal (GI) tract to exert their therapeutic efficacy. In vitro binding studies are used to assess bioequivalence (BE) of these products. The objective of this study is to identify the common deficiencies in Abbreviated New Drug Applications (ANDAs) for these products. Deficiencies were compiled from ANDAs containing in vitro binding BE studies. The deficiencies were classified into eight categories: Pre-Study Method Validation, During-Study Sample Analysis, Study Design, Study Procedure, Dissolution/Disintegration, Analytical Site Inspection, Data Submission, and Formulations...

BACKGROUND AND STUDY AIMS: Obscure gastrointestinal bleeding (OGIB) is defined as bleeding of unknown origin that persists or recurs after an initial negative investigation. Identifying the source of OGIB represents a diagnostic challenge that is frequently focused on visualizing the small intestine. Conventional diagnostic methods, such as push enteroscopy, small-bowel follow-through, radionuclide scanning, and angiography, each exhibit inherent limitations. Double balloon enteroscopy (DBE) was designed specifically to evaluate the entire small bowel...

BACKGROUND: To reduce unnecessary ambulatory gastroenterology (GI) visits and increase access to GI care, San Francisco Health Network gastroenterologists and primary care providers implemented guidelines in 2013 that discharged certain patients back to primary care after endoscopy with formal written recommendations. This study assesses the longer-term impact of this policy on GI clinic access, workflow, and provider satisfaction. METHODS: An email-based survey assessed gastroenterologist and primary care provider (PCP) opinions about the discharge process...

As a chronic inflammatory disease with eosinophilic infiltrate of the esophagus, eosinophilic esophagitis (EoE) causes a variety of gastrointestinal (GI) clinical manifestations. None of the symptoms, endoscopic features, or biopsy findings is pathognomonic of the disease, even with high degrees of esophageal eosinophilia. The pathogenesis has been explored by several studies, yet it still far from being completely understood. Evidence supports a role of allergen-driven Th2 lymphocyte mechanism, though not in every patient...

Eosinophilic esophagitis (EoE) is an allergic disease of the esophagus driven by T cell and eosinophil responses to dietary allergens, resulting in chronic mucosal inflammation. Few spontaneous animal models of esophageal eosinophilia exist, with most studies relying on artificial sensitization procedures. NF-κB-inducing kinase (NIK; MAP3K14) is a key signaling molecule of the noncanonical NF-κB (NFKB1) pathway, an alternative signaling cascade producing chemokines involved in lymphoid stroma development and leukocyte trafficking...

Gastrointestinal (GI) endoscopy plays an indispensable role in the diagnosis and management of various pediatric GI disorders. While the pace of development of pediatric GI endoscopy has increased over the years, it remains sluggish compared to the advancements in GI endoscopic interventions available in adults. The predominant reasons that explain this observation include lack of formal training courses in advanced pediatric GI interventions, economic constraints in establishing a pediatric endoscopy unit, and unavailability of pediatric-specific devices and accessories...

We investigated the effects of enteral tube feeding in Korean children with mitochondrial diseases. We performed a retrospective chart review of 68 paediatric patients with mitochondrial diseases on enteral tube feeding at a tertiary referral centre. The outcome of enteral nutrition was evaluated by decrease in gastrointestinal (GI) symptoms, weight gain, and increase in developmental quotient (DQ) among patients with data available. Among 68 patients, 56 (82%) were on gastrostomy and 12 (18%) were on prolonged nasogastric (NG) tube feeding...

Shellfish contamination by human noroviruses (HuNoVs) is a serious health and economic problem. Recently an ISO procedure based on RT-qPCR for the quantitative detection of HuNoVs in shellfish has been issued, but these procedures cannot discriminate between inactivated and potentially infectious viruses. The aim of the present study was to optimize a pretreatment using PMAxx to better discriminate between intact and heat-treated HuNoVs in shellfish and sewage. To this end, the optimal conditions (30min incubation with 100μM of PMAxx and 0...
