INTRODUCTION: The incidence of gastrointestinal disorders among patients with chronic kidney disease (CKD) is high, despite the lack of a good correlation between endoscopic findings and symptoms. Many services thus perform upper gastrointestinal (UGI) endoscopy on kidney transplant candidates. OBJECTIVES: This study aims to describe the alterations seen on the upper endoscopies of 96 kidney-transplant candidates seen from 2014 to 2015. METHODS: Ninety-six CKD patients underwent upper endoscopic examination as part of the preparation to receive kidney grafts...

Ka-Shing Cheung, Wai K Leung
Helicobacter pylori ( H. pylori ) infection is the most important risk factor for gastric cancer (GC) development through the Correa's gastric carcinogenesis cascade. However, H. pylori eradication alone does not eliminate GC, as pre-neoplastic lesions (atrophic gastritis, intestinal metaplasia and dysplasia) may have already developed in some patients. It is therefore necessary to identify patients at high-risk for gastric cancer after H. pylori eradication to streamline the management plan. If the patients have not undergone endoscopy with histologic assessment, the identification of certain clinical risk factors and non-invasive testing (serum pepsinogen) can predict the risk of atrophic gastritis...

Comminuted fractures of the anterior table of the frontal sinus involving frontonasal ducts are traditionally treated with sinus obliteration. This technique entails precise mucosa removal which requires unimpeded visualization of the bony recesses. To achieve adequate access to the mucosa, temporary removal of a large part of the frontal bone may often be necessary. This in turn increases fracture comminution requiring placement of additional hardware associated with the risk for bony malalignment, infection, plate palpability, and visibility, especially in thin-skin individuals...

Background: Gastric acidity could determine Helicobacter pylori ( H. pylori )-associated gastritis patterns. In reverse, H. pylori infection could lead disturbance in gastric acid secretion. We attempted to elucidate gastric acid status by conventional endoscopy with pepsinogen test. Methods: A total of 196 subjects who visited our health promotion center were consecutively enrolled and evaluated by conventional endoscopy, and blood examinations with pepsinogen I, II, and fasting serum gastrin were conducted...

Single nucleotide polymorphisms present on the promoter sequence of the TNF-α (Tumor necrosis factor alpha) gene may affect the production of TNF-α pro-inflammatory cytokine during immune response. Presence of TNF-α polymorphisms have also been reported to influence H. pylori infection, leading to increased disease severity. However, the frequency of TNF-α polymorphisms and the associated disease severity between different populations are contradictory. Gastric biopsy specimens and blood specimens were collected from 138 dyspeptic patients attending routine upper gastrointestinal endoscopy after obtaining written informed consent...

Background: Studies in experimental models and humans suggest that glucose‒6‒phosphate dehydrogenase (G6PD) deficiency, an inherited condition, may be inversely related to hepatocellular carcinoma (HCC). We tested this hypothesis in a large cohort of Sardinian patients. Methods: A case-control study was performed using data from 11,143 records of patients who underwent upper endoscopy between 2002 and 2017. Gender, age, G6PD status and information regarding the presence of HCC, were recorded. Cases (HCC positive) and controls (HCC negative) were compared for the presence of G6PD deficiency adjusting for major HCC risk factors using logistic regression...

Non-variceal upper gastrointestinal bleeding (NVUGIB) is bleeding that develops in the oesophagus, stomach or proximal duodenum. Peptic ulcers, caused by Helicobacter pylori infection or use of NSAIDs and low-dose aspirin (LDA), are the most common cause. Although the incidence and mortality associated with NVUGIB have been decreasing owing to considerable advances in the prevention and management of NVUGIB over the past 20 years, it remains a common clinical problem with an annual incidence of ∼67 per 100,000 individuals in the United States in 2012...

Gastric intestinal metaplasia is a precancerous change of the mucosa of the stomach with intestinal epithelium, and is associated with an increased risk of dysplasia and cancer. The pathogenesis to gastric cancer is proposed by the Correa hypothesis as the transition from normal gastric epithelium to invasive cancer via inflammation followed by intramucosal cancer and invasion. Multiple risk factors have been associated with the development of gastric intestinal metaplasia interplay, including Helicobacter pylori infection and associated genomics, host genetic factors, environmental milieu, rheumatologic disorders, diet, and intestinal microbiota...

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...
