Maham Hayat, Sultan Mahmood, John T Maple
A 62-year-old male with long-standing esophageal reflux underwent endoscopy at an outside institution that reported multiple polypoid lesions in upper esophagus and a small focal area of nodular mucosa at the gastroesophageal junction(GEJ). Biopsies of the proximal esophageal polyps demonstrated hyperplastic mucosa with ulceration, reactive epithelial changes, and focal intestinal metaplasia. Biopsies from the nodular GEJ mucosa were described as Barrett's esophagus with low grade dysplasia. An upper endoscopy performed at our medical center found multiple semi-pedunculated esophageal polyps between 18-24 cm from the incisors (Figure A)...

Histidine decarboxylase (HDC) is the primary enzyme that catalyzes the conversion of histidine to histamine. HDC contributes to many physiological responses as histamine plays important roles in allergic reaction, neurological response, gastric acid secretion, and cell proliferation and differentiation. Small-molecule modulation of HDC represents a potential therapeutic strategy for a range of histamine-associated diseases, including inflammatory disease, neurological disorders, gastric ulcers, and select cancers...

BACKGROUND: Primary aortoduodenal fistula (ADF) is a rare cause of gastrointestinal (GI) bleeding and is difficult to diagnose as the clinical presentation is subtle. Clinicians should keep a high level of suspicion for an unknown etiology of GI bleeding, especially in older patients with or without abdominal aortic aneurysm (AAA). Computed tomographic angiography (CTA) can be used to detect primary ADF. Open surgery or endovascular aortic repair (EVAR) for ADF with bleeding will improve the survival rate...

Ulceration of the non-glandular part of the stomach is a common disease entity of pigs worldwide, with prevalences of up to 93%. It may result in decreased daily weight gain, decreased feed intake and sudden death, thus leading to significant economic losses, as well as animal welfare issues. The aetiology is multifactorial. Diet particle size, management and infectious agents have been hypothesised to be involved. The exact mechanism behind porcine gastric ulceration is, however, not completely clear. The aim of this article is to provide an overview of the role of infectious agents in the development of porcine gastric ulceration...

BACKGROUND: Currently, it is still unclear whether adding a mucoprotective agent to a Proton Pump Inhibitor (PPI) results in better outcomes compared to using a PPI alone in patients with post-gastric endoscopic submucosal dissection (ESD) ulcers. This study aimed to examine the efficacy of PPI alone versus combination treatment in healing of post-gastric ESD ulcers, as well as on delayed bleeding and amount of blood transfused. METHODS: A systematic search of MEDLINE, EMBASE, Cochrane, and ISI Web of knowledge databases, up until May 2017, for randomized trials comparing PPI alone versus PPI plus a mucoprotective drug in achieving ulcer healing in patients undergoing gastric ESD was performed...
