BACKGROUND/AIM: Collision of Epstein-Barr virus (EBV)-associated lymphoepithelioma-like carcinoma (LELC) with non-Hodgkin's lymphoma of the stomach is extremely rare. PATIENTS AND METHODS: Herein we report a case of LELC with primary diffuse large B-cell lymphoma (DLBCL) of the stomach in a 65-year-old patient. RESULTS: Gastric endoscopy showed a poorly differentiated adenocarcinoma of the stomach. The patient underwent radical gastrectomy, and histopathological examinations revealed the collision of LELC and DLBCL of the stomach...

PURPOSE OF REVIEW: The discovery of Helicobacter pylori and other organisms colonizing the stomach and the intestines has shed some light on the importance of microbiome in maintaining overall health and developing pathological conditions when alterations in biodiversity are present. The gastric acidity plays a crucial role in filtering out bacteria and preventing development of enteric infections. In this article, we discuss the physiology of gastric acid secretion and bacterial contribution to the composition of gastric and intestinal barriers and review the current literature on the role of proton pump inhibitors (PPIs) in the microbial biodiversity of the gastrointestinal tract...

Māori, the indigenous people of New Zealand, experience disproportionate rates of stomach cancer, compared to non-Māori. The overall aim of the study was to better understand the reasons for the considerable excess of stomach cancer in Māori and to identify priorities for prevention. Māori stomach cancer cases from the New Zealand Cancer Registry between 1 February 2009 and 31 October 2013 and Māori controls, randomly selected from the New Zealand electoral roll were matched by 5-year age bands to cases...

The first histamine H2 receptor antagonists (H2RAs) were developed in the early 1970s. They played a dominant role in treating peptic ulcer disease and gastroesophageal reflux disease (GERD). H2RAs block the production of acid by H(+), K(+)-ATPase at the parietal cells and produce gastric luminal anacidity for varying periods. H2RAs are highly selective, and they do not affect H1 receptors. Moreover, they are not anticholinergic agents. Sequential development of H2RAs, proton pump inhibitors (PPIs), and discovery of Helicobacter pylori infection changed the paradigm of peptic ulcer disease with marked decrease of morbidity and mortality...

The French heartworm Angiostongylus vasorum is found in European red fox (Vulpes vulpes) and dog populations, where it appears to be spreading geographically. Once introduced into new areas, it establishes in local fox populations, typically to over 50% prevalence in a few years. High susceptibility and constant excretion of first stage larvae (L1) by the definitive hosts are prerequisites for sustaining high parasite biomass in a particular habitat. The present study explores the hypothesis that repeated ingestion of gastropods in nature will result in accumulation of adult worms and elevated excretion of L1 in feces...

Epidemiological and pathological studies of Helicobacter spp. in canine stomachs in Japan were performed to investigate strain specific pathogenicity. Gastric biopsies from 144 dogs with gastrointestinal diseases were evaluated for the presence of Helicobacter spp. using genus and species specific PCRs for Helicobacter felis, Helicobacter bizzozeronii, Helicobacter heilmannii sensu stricto (s.s.) and Helicobacter pylori. PCR indicated that 50/144 (34.7%) dogs were infected with Helicobacter spp. Of the genus positive samples, 21/50 could not be amplified by any of the species specific PCRs...

An association between heavy alcohol drinking and gastric cancer risk has been recently reported, but the issue is still open to discussion and quantification. We investigated the role of alcohol drinking on gastric cancer risk in the "Stomach cancer Pooling (StoP) Project", a pooled analysis of case-control studies. A total of 9,669 cases and 25,336 controls from 20 studies from Europe, Asia and North America were included. We estimated summary odds-ratios (ORs) and the corresponding 95% confidence intervals (CIs) by pooling study-specific ORs using random-effects meta-regression models...

A 56-year-old man with gastroesophageal reflux disease (GERD) was referred to our hospital. Esophagogastroduodenoscopy (EGD) revealed no evidence of any polypoid lesions in the stomach, and the patient had no history of Helicobacter pylori infection. He received omeprazole (20 mg) once daily for the GERD. EGD was performed at 1 year after the start of omeprazole administration, and this time, gastric hyperplastic polyps (GHPs) were detected. The GHPs increased in size as the omeprazole treatment continued, but they markedly decreased in size following omeprazole discontinuation...

BACKGROUND: Fungal infection of the toenails, also called onychomycosis, is a common problem that causes damage to the nail's structure and physical appearance. For those severely affected, it can interfere with normal daily activities. Treatment is taken orally or applied topically; however, traditionally topical treatments have low success rates due to the nail's physical properties. Oral treatments also appear to have shorter treatment times and better cure rates. Our review will assist those needing to make an evidence-based choice for treatment...

The high incidence rate of multiple carcinomas in the upper digestive tract is often explained in terms of involvement of the same underlying risk factors. It has been reported that the oral bacterium Streptococcus anginosus is associated with esophageal, gastric, and pharyngeal cancers. We previously reported occurrence of Porphyromonas gingivalis (P. gingivalis) DNA in esophagus cancer. In this study, the presence of P. gingivalis in specimens of various types of cancer from the upper digestive tract was investigated...

Anisakis spp. is a parasitic nematode whose infective third-stage larvae may be found within the flesh of fish species commonly consumed by humans. Thorough cooking or freezing should render the fish safe for consumption; furthermore, marinating solutions containing biocidal agents might have a significant action against Anisakis larvae. Some studies suggest a relationship between some parasitic infections and development of inflammatory bowel disorders, and Anisakis infection might be a risk factor for stomach or colon cancer...

BACKGROUND AND AIM: Inflammatory changes in the stomach caused by Helicobacter pylori indirectly and directly affect liver function. Moreover, the bacteria may worsen the course of the liver cirrhosis. The study aimed at evaluating the incidence of H. pylori infection among patients with liver cirrhosis, depending on the etiology and injury stage, scored according to Child-Pugh classification. Stage of esophageal varices and endoscopic inflammatory lesions in the stomach were evaluated, depending on the presence of H...

Therapy with checkpoint inhibitors represents a major advance in cancer treatment. The purpose of this study was to examine the expression patterns of the checkpoint proteins programmed death ligand 1 (PD L1), PD L2, indoleamine 2,3-dioxygenase 1 (IDO1), and cytotoxic T-lymphocyte antigen 4 (CTLA4) in cancers including those associated with viral infections. Normal, noninflamed tissues rarely express checkpoint proteins with exceptions including the placenta and stomach. Expression of PD L1 was noted in 30%, PD L2 in 18%, IDO1 in 13%, and CTLA4 in 14% of 333 nonviral malignancies including endometrial, ovarian, lung, and breast cancers...

Emerging evidence shows that the human microbiota plays a larger role in disease progression and health than previously anticipated. Helicobacter pylori, the causative agent of gastric cancer and duodenal and gastric ulcers, was early associated with gastric disease, but it has also been proposed that the accompanying microbiota in Helicobacter pylori-infected individuals might affect disease progression and gastric cancer development. In this study, the composition of the transcriptionally active microbial community and the H...

Persistent stomach infection with Helicobacter pylori causes chronic mucosal inflammation (gastritis), which is widely recognized as an essential precursor to gastric cancer. The IL-1 interleukin family cytokines IL-1β and IL-18 have emerged as central mediators of mucosal inflammation. Here, we review the regulation and function of these cytokines in H. pylori-induced inflammation and carcinogenesis.

BACKGROUND AND OBJECTIVES: Endoscopic ultrasound-guided hepaticogastrostomy (EUS-HGS) represents an option to treat obstructive jaundice when endoscopic retrograde cholangiopancreatography (ERCP) fails. The success rate of this procedure has been shown to be very high. Up to now, plastic and self-expandable metallic stents (SEMSs) have been employed, each of them presenting some limitations. The aims of this study were to evaluate the technical and functional success rates of EUS-HGS using a dedicated biliary SEMS with a half-covered part (Giobor® stent)...

H. pylori is a Gram-negative extracellular bacterium, first discovered by the Australian physicians Barry Marshall and Robin Warren in 1982, that colonises the human stomach mucosa. It is the leading cause of peptic ulcer and commonly infects humans worldwide with prevalence as high as 90% in some countries. H. pylori infection usually results in asymptomatic chronic gastritis, however 10-15% of cases develop duodenal or gastric ulcers and 1-3% develop stomach cancer. Infection is generally acquired during childhood and persists for life in the absence of antibiotic treatment...

BACKGROUND: Chronic infection with Helicobacter pylori leads to gastritis and in a subpopulation of infected individuals to ulcers and cancer. Bacterial virulence factors and host immune inflammatory responses are risk factors related to disease. CD4(+) T cells secrete cytokines that promote inflammation and an anti-bacterial response in the gastric mucosa during infection. The aim of the study was to investigate the pattern of expression of CD4(+) T cell derived cytokines, IL-17A and IFNγ in paired antrum and corpus biopsies and correlate it to H...

Functional dyspepsia can be categorized into two syndromes: postprandial distress syndrome and epigastric pain syndrome. Helicobacter pyloriinfection is one of the most common chronic infections worldwide. Acute H pylori infection causes dyspepsia, and chronic infection can cause peptic ulcer disease. H pylori also is one of the causative agents in gastric adenocarcinoma and mucosa-associated lymphoid tissue lymphoma. The incidence of H pylori infection varies among different ethnic populations and geographic locations...
