Prader-Willi syndrome (PWS) is a genetic syndrome in which individuals have multisystem medical challenges. Gastroenterological difficulties in the syndrome include decreased vomiting, constipation, delayed gastric emptying, delayed colonic transit, dysphagia, increased choking, and increased risk of gastric dilation and rupture. In addition, self-injurious behavior such as rectal picking may be present and severe enough to lead to rectal ulceration and bleeding. Many patients have extensive gastroenterological workup and treatment before their ultimate diagnosis of severe rectal picking...

Medication control and doping control have been established in horse racing to ensure the integrity of the sport and the welfare of the horses. This ensures that horses do not compete under the influence of any drugs, including omeprazole, a therapeutic medication used to treat equine gastric ulcer syndrome. In this study, pharmacokinetic data were produced in equine plasma and urine following an oral administration of 4 mg/kg of generic buffered formulation of omeprazole to six Thoroughbred horses in five daily doses to determine an appropriate screening limit and detection time in equine plasma and to assess whether the current detection time of 72 hr in equine urine would be applicable when an alternative omeprazole product is administered...

The Gram-negative bacterium, Helicobacter pylori , causes chronic gastritis, peptic ulcers, and gastric cancer in humans. Although the gastric epithelium is the primary site of H. pylori colonization, H. pylori can gain access to deeper tissues. Concurring with this notion, H. pylori has been found in the vicinity of endothelial cells in gastric submucosa. Endothelial cells play crucial roles in innate immune response, wound healing and tumorigenesis. This study examines the molecular mechanisms by which H...

Transarterial chemoembolisation (TACE) is commonly used for unresectable intermediate-stage hepatocellular carcinoma (HCC). TACE is usually well-tolerated. We report a case of a patient who presented with a gastrointestinal bleed from TACE. A 64-year-old man presented with chronic hepatitis C cirrhosis and multifocal bilobar HCC. He had previously undergone multiple TACE sessions, radiofrequency ablation and stereotactic body radiation therapy. In the evening of his TACE procedure, he developed abdominal pain and haematemesis...

The efficacy of proton beam therapy (PBT) for hepatocellular carcinoma (HCC) has been reported, but insertion of fiducial markers in the liver is usually required. We evaluated the efficacy and toxicity of respiratory-gated PBT without fiducial markers for HCC located within 2 cm of the gastrointestinal tract. From March 2011 to December 2015 at our institution, 40 patients were evaluated (median age, 72 years; range, 38-87 years). All patients underwent PBT at a dose of 60 to 80 cobalt gray equivalents (CGE) in 20 to 38 fractions...

Globally, gastric ulcer is a vital health hazard for a human. Rabdosia inflexa (RI) has been used in traditional medicine for inflammatory diseases. The present study aimed to investigate the protective effect and related molecular mechanism of RI using lipopolysaccharide (LPS)-induced inflammation in RAW 246.7 cells and HCl/EtOH-induced gastric ulcer in mice. We applied 3-(4,5-dimethyl-thiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT), nitric oxide (NO), reactive oxygen species (ROS), histopathology, malondialdehyde (MDA), quantitative real-time polymerase chain reaction (qPCR), immunohistochemistry (IHC), and Western blot analyses to evaluate the protective role of RI...

Lysophosphatidic acid (LPA) is a bioactive phospholipid that induces diverse biological responses. Recently, we found that LPA ameliorates NSAIDs-induced gastric ulcer in mice. Here, we quantified LPA in 21 medicinal herbs used for treatment of gastrointestinal (GI) disorders. We found that half of them contained LPA at relatively high levels (40-240 μg/g) compared to soybean seed powder (4.6 μg/g), which we previously identified as an LPA-rich food. The LPA in peony (Paeonia lactiflora) root powder is highly concentrated in the lipid fraction that ameliorates indomethacin-induced gastric ulcer in mice...

The Surgical Apgar Score (SAS) is a simple and rapid scoring system predicting postoperative mortality and morbidity. However, it remains unknown whether it might be useful in fit and frail older patients undergoing abdominal emergency surgery. METHODS: Consecutive patients ≥65 years, needing emergency abdominal surgery were enrolled in this prospective study. Additionally to the SAS, the G8 screening score was used to determine the frailty status. The logistic regression analysis was conducted investigating the association between the scores and 30-day postoperative outcomes...

Central nervous system (CNS) infection of C57BL/6 mice with the TE strain of Sindbis virus (SINV) provides a valuable animal model for studying the pathogenesis of alphavirus encephalomyelitis. While SINV TE inoculated intracranially causes little mortality, 20-30 % of mice inoculated intranasally (IN) died 8 to 11 days after infection, the period during which immune cells typically infiltrate the brain and clear infectious virus. To examine the mechanism behind the mortality, mice infected IN with SINV TE were monitored for evidence of neurological disease, and those with signs of severe disease (moribund) were sacrificed and tissues collected...

Helicobacter pylori (H. pylori) is a Gram-negative bacterium, usually acquired during childhood, whose natural habitat is the gastric lumen. H. pylori is accepted as the most important cause of gastritis and peptic ulcer in humans. Nevertheless, its important role in the pathogenesis of gastric cancer as well as in several extra-gastroduodenal diseases has been confirmed. The aim of this work is to discuss, for the first time in a single article, all publications concerning H. pylori infection arising from Piedmont region, Italy, where in 1893 Giulio Bizzozero was the first who observed and described spiral organisms in the stomach of animal models...

The subject of Helicobacter pylori continues to elicit worldwide interest in many research fields. Epidemiological data suggest that the prevalence of the infection is decreasing in Western/developed countries and even in some developing regions, but this is masked by the high prevalence in the most populous regions. Chronic gastritis, caused invariably by the bacterium, was again classified in Kyoto and Helicobacter pylori-associated gastritis was included as a distinct entity. The prevalence of peptic ulcers is decreasing, but bleeding ulcers are a challenging problem, with stable mortality levels even in the endoscopic era...

Peptic ulcer is a lesion in the mucosa of the digestive tract affecting many people all around the world. Recent investigations have indicated that produced inflammatory cytokines such as TNF-α and IL-1β in response to gastric infection by Helicobacter pylori play an important role in the development of peptic ulcer. With regard to the significance of these cytokines in peptic ulcer development and the high prevalence of this disease in the developing countries, this study aimed to investigate the association of TNF-α and IL-1β with peptic ulcer in the presence of H...

The gastroprotective activity of Hericium erinaceus polysaccharide was investigated in rats. The antioxidant activities were also evaluated. Pre-treatment of polysaccharide could reduce ethanol-induced gastric mucosal lesion and pylorus ligation-induced gastric ulcer. The polysaccharide exhibited scavenging activities of 1, 1-diphenyl-2-picryl-hydrozyl and hydroxyl radicals, and ferrous ion-chelating ability. In the pylorus ligation-induced model, gastric secretions (volume of gastric juice, gastric acid, pepsin and mucus) of ulcer rats administrated with polysaccharide were regulated...

Herein, we describe a rare case of refractory gastric antral ulcers. A woman in her 50 s was admitted to Nagoya City University Hospital with epigastric pain after being diagnosed with gastric antral submucosal tumor at another hospital. Findings from esophagogastroduodenoscopy and endoscopic ultrasound examination revealed that the lesion was a gastric ulcer. The patient had no Helicobacter pylori infection and no recent history of using non-steroidal anti-inflammatory drugs. On the basis of these findings, we diagnosed this as a case of refractory gastric antral ulcer (RGAU)...
