BACKGROUND: Amputation neuromas (ANs) are reactive hyperplasia of nerve tissues that occur after a trauma or surgery involving the peripheral nerves. Only two previous reports of ANs occurring around the stomach and post gastrectomy have been reported. We report the case of a patient with AN near the remnant stomach who underwent distal gastrectomy for gastric cancer. CASE PRESENTATION: A 76-year-old man underwent distal gastrectomy, D1+ lymphadenectomy, and Billroth-I reconstruction for early gastric cancer in another hospital at 63 years of age...

Extranodal marginal zone lymphoma (EMZL), mostly represented by mucosa-associated lymphoid tissue (MALT) type, also referred to as MALT lymphoma, is a clinically heterogeneous entity within the group of low-grade B cell lymphomas that arises in a wide range of different extranodal sites, including the stomach, lung, ocular adnexa, and skin. It represents the third most common non-Hodgkin lymphoma in the Western world, and the median age of occurrence is around 60 years. One characteristic aspect in a subset of EMZL detectable in about 25% of the cases is the presence of specific chromosomal translocations involving the genes MALT1 and BCL10, which lead to activation of the NF-κB signaling pathway...

In this case report, we describe two patients who showed a diffusely whitish mucosa in the posterior wall and the lesser curvature of the gastric body. The patients were serologically- and histopathologically-negative for Helicobacter pylori. Random biopsy specimens from the stomach revealed no regenerative changes, intestinal metaplasia, and/or foveolar hyperplasia in either of the patients. Although lanthanum deposition in the gastric mucosa has been reported to occur in close association with H. pylori-associated gastritis, our patients tested negative for H...

Several studies have shown the protective effect of dairy products, especially α-lactalbumin and derived hydrolysates, against induced gastric ulcerative lesions. The mucus strengthening represents an important mechanism in the defense of gastrointestinal mucosa. Previously, a hydrolysate from casein (CNH) and a hydrolysate from whey protein concentrate rich in β-lactoglobulin (WPH) demonstrated a stimulatory activity on mucus production in intestinal goblet cells. The aim of this work was to evaluate the possible antiulcerative activity of these two hydrolysates in an ethanol-induced ulcer model in rats...

The elective background for gastric adenocarcinoma is the atrophic transformation of the gastric mucosa. The extent of mucosal atrophy basically parallels the risk of developing gastric cancer. This means that either noninvasive (serology) or invasive (endoscopy/histology) methods enabling the atrophic transformation to be quantified can be used theoretically to assess a given patient's gastric cancer risk. This review aims to focus on the reliability of histology gastritis Operative Link for Gastritis Assessment -staging system for assessing the 'personalized' cancer risk in individuals with (atrophic) gastritis...

BACKGROUND: Although Helicobacter-induced gastric inflammation is the major predisposing factor for gastric carcinogenesis, the precise mechanism by which chronic gastritis causes gastric cancer remains unclear. Intestinal and spasmolytic polypeptide-expressing metaplasia (SPEM) is considered as precancerous lesions, changes in epithelial tissue stem/progenitor cells after chronic inflammation has not been clarified yet. In this study, we utilized three-dimensional gastric epithelial cell culture systems that could form organoids, mimicking gastric epithelial layer, and characterized the changes in epithelial cells after chronic Helicobacter felis infection...

Amyloidosis is a rare disease (incidence about 0.8/100 000) characterized by extracellular tissue deposition of fibrils composed of low molecular weight subunits of a variety of serum proteins. Clinical manifestations are largely determined by the type of precursor protein, the tissue distribution and the amount of amyloid deposition. Gastrointestinal (GI) manifestations of amyloidosis are even more uncommon (3 % of all amyloidosis patients). Symptoms of GI amyloidosis are nonspecific, heterogeneous, and include weight loss, GI bleeding, heartburn, early satiety, diarrhea and abdominal pain...

The abnormal expression of the chicken ovalbumin upstream promoter transcription factor 2 (COUP‑TFII) is associated with numerous forms of cancer, including gastric, prostate, colon and lung cancer. However, previous studies investigating the association between COUP‑TFII expression and the occurrence, recurrence, invasion and metastasis of gastric cancer are limited in number. In the present study, it was revealed that the expression of COUP‑TFII is significantly reduced in gastric carcinoma tissues compared with normal gastric mucosa cells (GES‑1)...

Cervical inlet patch (CIP), also referred to as esophageal heterotopic gastric mucosa, is regarded as the residue of columnar epithelium of the embryonic esophagus. Narrow band imaging increases the detection rate of CIP. Herein, we present a 55-year-old man with symptomatic circumferential inlet patch. He exhibited globus and dysphagia, and esophagogastroduodenoscopy found cir-cumferential CIP, where im-munohistochemistry revealed the existence of pro-ton pumps (H+, K+-ATPase). His throat symptoms were relieved by acid suppressive therapy with pump inhibitors...

AIM: To establish a rat model of anxiety-like gastric hypersensitivity (GHS) of functional dyspepsia (FD) induced by novel sequential stress. METHODS: Animal pups were divided into two groups from postnatal day 2: controls and the sequential-stress-treated. The sequential-stress-treated group received maternal separation and acute gastric irritation early in life and restraint stress in adulthood; controls were reared undisturbed with their mothers. Rats in both groups were followed to adulthood (8 wk) at which point the anxiety-like behaviors and visceromotor responses to gastric distention (20-100 mmHg) and gastric emptying were tested...

REVIEW
Kevin S Johnson, Karen M Ottemann
Helicobacter pylori is a Gram-negative bacterium that infects half of the world's population, causing gastritis, peptic ulcers, and gastric cancer. To establish chronic stomach infection, H. pylori utilizes chemotaxis, driven by a conserved signal transduction system. Chemotaxis allows H. pylori to sense an array of environmental and bacterial signals within the stomach, guiding its motility towards its preferred niche within the gastric mucosa and glands. Fine-tuned localization, regulated by the chemotaxis system, enables robust colonization during the acute stage of infection...

Ferric uptake regulator (Fur) of Helicobacter pylori is a global regulator that is important for bacterial colonization and survival within the gastric mucosa. H. pylori Fur (HpFur) is unique in its ability to regulate gene expression in both metal-bound (holo-Fur) and metal-free (apo-Fur) forms. Bismuth-based drugs are widely used for the treatment of H. pylori infection. However, the mechanism of action of bismuth drug was not fully understood. Recently, it has been reported that bismuth drugs could interfere with the bacterial ferric uptake pathway and inhibit bacterial growth, implying intrinsic correlation between bismuth drug and bacterial iron metabolism...

The association between inflammation and cancer has long been recognized. Several studies have found that different types of tumors develop at sites of chronic inflammation. It is stated that over 15%-20% of malignancies worldwide can be related to infections caused by viruses, bacteria, and schistosomes. Inflammatory conditions are characterized by overexpression of inducible nitric oxide synthase (iNOS) and overproduction of nitric oxide/reactive nitrogen species (ROSs/RNSs) in epithelial cells. Reactive oxygen species (ROSs) may also lead to cellular alterations and eventually to inflammation...
