INTRODUCTION: Gastropleural fistula (GPF) is a complex pathology that can present as a result of surgery, trauma, peptic ulcer disease, malignancies, radiation, or chemotherapy. Management typically includes endoscopic or surgical intervention along with intraabdominal or intrathoracic drainage of pre-existing infection. Traditionally, surgical approaches have been through exploratory laparotomy or thoracotomy, subjecting already ill patients to additional morbidity. CASE REPORT: We describe and demonstrate a laparoscopic minimally invasive approach to the management of a GPF with a wedge resection of the stomach, along with a review of the current literature regarding GPF treatment...

Enteral tube feeding is the delivery of nutritionally complete feed via a tube into the gut. It is used for patients who are unable to meet their nutritional needs orally. Enteral feeding can be given through a variety of different tubes that access the gastrointestinal tract either via the stomach or the small bowel. The contamination of enteral feed can often be overlooked as a source of bacterial infection. Enteral feeds can become contaminated in a variety of different ways. Most often infections result in extended lengths of stay in hospital and patients also need additional therapies and treatments in order to resolve these infections...

Helicobacter pylori colonizes the gastric mucosa in the human stomach and represents a major risk factor for peptic ulcer disease and gastric cancer. Here, we summarize our current knowledge of the complex impact of H. pylori on manipulating host signalling networks, that is, by the cag pathogenicity island (cagPAI)-encoded type IV secretion system (T4SS). We show that H. pylori infections reflect a paradigm for interspecies contact-dependent molecular communication, which includes the disruption of cell-cell junctions and cytoskeletal rearrangements, as well as proinflammatory, cell cycle-related, proliferative, antiapoptotic, and DNA damage responses...

Stomach infection with Helicobacter pylori (H. pylori) causes severe gastroduodenal diseases in a large number of patients worldwide. The H. pylori infection breaks up in early childhood, persists lifelong if not treated, and is associated with chronic gastritis and an increased risk of peptic ulcers and gastric cancer. In recent years, the problem of drug-resistant strains has become a global concern that makes the treatment more complicated and the infection persistent at higher levels when the antibiotic treatment is stopped...

The protozoan parasite Toxoplasma gondii is one of the most important food-related pathogens worldwide. Besides contact to oocysts or ingestion of tissue cysts mainly by consumption of raw or undercooked meat from infected animals, raw milk is considered to be a risk factor and possible route of transmission for tachyzoites. This stage of the parasite is usually very sensitive to acidic pH and, therefore, considered unlikely to survive stomach passage. However, tachyzoites were shown to survive for several days in milk and there are also reports on transmission of toxoplasmosis via milk...

Parasitic nematodes of Oesophagostomum spp., commonly known as 'nodular worms' are one of the most widely distributed and prevalent emerging zoonotic nematodes. However, little is known about the prevalence and gene characteristics of those parasites in Tibetan pigs. Therefore, a study was carried out to investigate the prevalence, isolation and identification of Oesophagostomum spp from Tibetan pigs by genetic markers of nad1,cox3 and ITS1 for the first time. The results revealed that the infection rate of O...

Helicobacter pylori (H. pylori) is a gastric human pathogen associated with acute and chronic gastritis, 70% of all gastric ulcers, 85% of all duodenal ulcers, and both forms of stomach cancer, mucosal-associated lymphoid tissue (MALT) lymphoma and adenocarcinoma. Recently, attention has focused on possible relationship between presence of certain virulence factor and H. pylori-associated diseases. Some contradictory data between this bacterium and related disorders has been observed since not all the colonized individuals develop to severe disease...

Leucine rich repeat (LRR) motif exists in many immune receptors of animals and plants. Most LRR containing (LRRC) proteins are involved in protein-ligand and protein-protein interaction, but the exact functions of most LRRC proteins were not well-studied. In this study, an LRRC protein was identified from kuruma shrimp Marsupenaeus japonicus, and named as MjLRRC1. MjLRRC1 was consistently expressed in different tissues of normal shrimp with higher expression in gills and stomach. At the transcriptional level, there were no significant changes of MjLRRC1 after injection of Vibrio anguillarum or Staphylococcus aureus in gills and hepatopancreas...

We developed a PCR assay targeting the 28S rDNA of Kudoa iwatai (Multivalvulida: Myxozoa) and investigated the prevalence of infection in rock bream Oplegnathus fasciatus, which is commercially an important aquaculture species in Korea, with this assay. Detection limit of the PCR assay was 2.5 fg/μl with plasmid DNA and 8.6 × 10(3) spores/ml with purified spores, respectively. This PCR assay did not amplify DNA of other Kudoa species (Kudoa septempunctata, Kudoa lateolabracis, Kudoa thyrsites) tested. Sliced muscles of whole body from 318 rock bream (wild and cultured) were examined by this PCR assay and also with the naked eyes...

Objectives. Helicobacter pylori infection is common and can lead to precancerous gastric lesions. Standard antibiotic therapy has a failure rate of more than 25% from antibiotic resistance. The primary aim of this observational pilot study was to test the feasibility of a large-scale clinical trial of Conifer Green Needle Complex (CGNC) to treat precancerous gastric lesions. Secondary aims were to investigate H. pylori infection, stomach function, and histopathology of the gastric mucosa. Methods. A tablet form of CGNC (extracted from Pinus sylvestris and Picea abies (L) Karst) was prescribed to 26 patients with precancerous gastric lesions (two tablets, 100 mg CGNC/tablet, three times per day for six months)...

BACKGROUND & AIMS: During aging, physiological changes in the stomach result in more tenuous gastric tissue that is less capable of repairing injury, leading to increased susceptibility to chronic ulceration. Spasmolytic polypeptide/trefoil factor 2-expressing metaplasia (SPEM) is known to emerge after parietal cell loss and during Helicobacter pylori infection, however, its role in gastric ulcer repair is unknown. Therefore, we sought to investigate if SPEM plays a role in epithelial regeneration...

Helicobacter pylori is an important cause of gastric pathologies and persistent infection can lead to stomach cancer. Virulent H. pylori strains encode a type IV secretion system responsible for translocation of the oncogenic CagA protein into cells of the gastric mucosa. Gene HP0522 encodes the essential component Cagδ (Cag3), and we show by gel filtration and cross-linking that purified Cagδ forms high molecular mass complexes. In contrast, its interaction partner CagT is mostly monomeric, but co-fractionates after gel filtration...

The frequency of molecular studies aimed to analyze promoter methylation of tumor suppressor genes and global proteomics in gastric carcinogenesis is increasing. Nonetheless, only a few considered the different types of stomach cells, the tumor location and the influence of Helicobacter pylori and Epstein Barr virus infection (EBV). Molecular differences relating to anatomical and histological tumor areas were also recently described. The authors propose a molecular classification of gastric cancer, dividing it into four subtypes: tumors positive for EBV; microsatellite unstable tumors; genomically stable tumors and tumors with chromosomal instability...

Helicobacter pylori commonly infects the epithelial layer of the human stomach and in some individuals causes peptic ulcers, gastric adenocarcinoma or gastric lymphoma. Helicobacter pylori is a genetically diverse species, and the most important bacterial virulence factor that increases the risk of developing disease, versus asymptomatic colonization, is the cytotoxin associated gene pathogenicity island (cagPAI). Socially housed rhesus macaques are often naturally infected with H. pylori similar to that which colonizes humans, but little is known about the cagPAI...
