Shaimaa Elkholy, Sherif Mogawer, Ali Farag
Nodular lymphoid hyperplasia (NLH) is a rare benign condition that is characterized by diffuse hyperplasia of the lymphoid follicles of the gastrointestinal tract (GIT). During endoscopy, NLH appears as multiple or occasionally innumerable nodules measuring a few millimeters in diameter. NLH occurs mainly in the small intestine, less commonly in the large intestine and rarely involves the stomach. There are multiple associated diseases such as immunoglobulin deficiency syndromes, giardiasis, Helicobacter pylori (H...

Cryptosporidiosis in raptors and falcons is well-known to be caused by Cryptosporidium baileyi and associated mainly with respiratory pathology. This report presents the diagnosis of an atypical cryptosporidiosis event caused by Cryptosporidium parvum, that to the authors' knowledge, is a case observed for the first time in falcons. Two falcons (Gyrfalcon x Peregrine hybrids) were presented for annual check without any clinical signs. Hematology, biochemistry, fecal and crop parasitology, radiographic and endoscopic examinations were performed...

Patients who undergo percutaneous endoscopic gastrostomy (PEG) placement are often on antiplatelet therapy. There is a potential risk of infarction if these medications are discontinued.The guidelines of the Japan Gastroenterological Endoscopy Society, classify PEG as an operation associated with a high risk of bleeding; however, it is known that surgery can be performed without interruption when patients are treated with low-dose aspirin alone. Nevertheless, we experienced the case of severe bleeding at the incision site, which was accompanied by massive hematemesis and hemorrhagic shock the night after PEG using the modified introducer method in an 87-year-old male patient...

The present study aimed to investigate whether single nucleotide polymorphisms in receptor interacting serine/threonine kinase 2 ( RIPK2 ), which encodes a component of the nucleotide binding oligomerization domain containing 2-RIP2 pathway, may compromise the innate immune response to Helicobacter pylori infection, leading to increased susceptibility to gastric cancer in the Japanese population. The present case control study investigated the associations between RIPK2 single nucleotide polymorphisms and gastric mucosal inflammation, atrophy and cancer susceptibility in 528 patients with gastric cancer and 697 patients without gastric malignancies on upper gastro-duodenal endoscopy...

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...

BACKGROUND: Outbreaks of transmission of infection related to endoscopy despite reported adherence to reprocessing guidelines, warrant scrutiny of all potential contributing factors. Recent reports from ambulatory surgery centers indicated widespread significant occult damage within endoscope working channels, raising concerns regarding the potential detrimental impact of this damage on the adequacy of endoscope reprocessing. METHODS: We inspected working channels of all 68 endoscopes at our academic institution using a novel flexible inspection endoscope...

Background and study aims : Helicobacter pylori (HP)-associated chronic gastritis can cause mucosal atrophy and intestinal metaplasia, both of which increase the risk of gastric cancer. The accurate diagnosis of HP infection during routine medical checks is important. We aimed to develop a convolutional neural network (CNN), which is a machine-learning algorithm similar to deep learning, capable of recognizing specific features of gastric endoscopy images. The goal behind developing such a system was to detect HP infection early, thus preventing gastric cancer...

BACKGROUND: Adenocarcinoma of the esophagogastric junction (EGJ) is uncommon in Eastern countries, including Japan, but it is believed that the incidence of EGJ adenocarcinoma will increase in Asia in the future due to the decreasing incidence of Helicobacter pylori infection. Endoscopic submucosal dissection (ESD) is a minimally invasive and curative treatment that allows precise pathological assessment. SUMMARY: Magnifying endoscopy with narrow-band imaging may be useful for differential diagnoses and for delineating the cancer margin of EGJ adenocarcinoma, but subsquamous carcinoma extension, which is the invasion of EGJ adenocarcinoma beneath the normal esophageal squamous epithelium, makes it difficult to detect cancer margins of the oral side in ESD for EGJ adenocarcinoma...

Purpose: Minimal change esophagitis (MCE) is a reflux disease without mucosal breaks, known to be partially associated with abnormal gastric motor function. Electrogastrography (EGG) is commonly applied to assess gastric motor function in a noninvasive fashion. We aimed to determine the relationship between MCE and gastric myoelectrical activity (GME) recorded on EGG in children. Methods: We retrospectively assessed the records of 157 children without underlying disease who underwent both EGG and upper gastrointestinal endoscopy at Gachon University Gil Medical Center between January 2010 and June 2015...

BACKGROUND: Celiac disease (CD) occurs in subjects positive for HLA-DQ2 and/or DQ8 gene loci at any age following ingestion of gluten-containing food. An increased permeability of the mucosa allows interactions between gliadin macromolecules and genetic factors. It has been observed that Helicobacter pylori has the ability to modulate the integrity of the duodenal epithelium. We aimed to determine whether H. pylori infection may enhance the occurrence of CD in genetically susceptible subjects...

BACKGROUND: Echinostomiasis is a food-borne infection caused by an intestinal trematodes belonging to the family Echinostomatidae. They infect the gastrointestinal tract of humans. Patients are usually asymptomatic. However, with heavy infections, the worms can produce catarrhal inflammation with mild ulceration and the patient may experience abdominal pain, anorexia, nausea, vomiting, diarrhea and weight loss. Infection are associated with common sociocultural practices of eating raw or insufficiently cooked mollusks and fish...

BACKGROUND: Helicobacter pylori (H. pylori) infection causes elevation of lipid peroxidation product malondialdehyde (MDA) and this association may be due to the bacterium causing reactive oxygen species-mediated damage to DNA in the gastric epithelium. The aim of this study was to investigate the gastric juice MDA levels in relation to H. pylori infection and associated gastric diseases. METHODS: Gastric juice samples were obtained from 117 patients undergoing endoscopy, and gastric juice MDA levels were determined by high-performance liquid chromatography (HPLC) system...

Postoperative leak is a serious complication of bariatric surgery and often results in significant morbidity and mortality. Stent placement is a less invasive alternative to surgery for the treatment of bariatric surgical leak. We evaluated the efficacy and complications of covered self-expandable metal stents (SEMS) in the treatment of post-bariatric surgical leak. We retrospectively reviewed patients who underwent stent placement for leak after bariatric surgery. Leak was diagnosed by upper gastrointestinal series or was visualized during the endoscopy...

Background: Helicobacter pylori affects almost half of the world's population and therefore is one of the most frequent and persistent bacterial infections worldwide. H. pylori is associated with chronic gastritis, ulcer disease (gastric and duodenal), mucosa-associated lymphoid tissue lymphoma, and gastric cancer. Several diagnostic methods exist to detect infection and the option of one method or another depends on various genes, such as availability, advantages and disadvantages of each method, monetary value, and the age of patients...
