Oral and Gut Microbial Dysbiosis and Non-alcoholic Fatty Liver Disease: The Central Role of .

Gut microbiota play many important roles, such as the regulation of immunity and barrier function in the intestine, and are crucial for maintaining homeostasis in living organisms. The disruption in microbiota is called dysbiosis, which has been associated with various chronic inflammatory conditions, food allergies, colorectal cancer, etc. The gut microbiota is also affected by several other factors such as diet, antibiotics and other medications, or bacterial and viral infections.

A case of canalicular adenoma with anemia.

Supplementation with Branched-Chain Amino Acids Induces Unexpected Deleterious Effects on Astrocyte Survival and Intracellular Metabolism with or without Hyperammonemia: A Preliminary In Vitro Study.

Introduction: Ammonia is a key component in the pathogenesis of hepatic encephalopathy. Branched-chain amino acids (BCAA) have been reported to improve the symptoms of HE induced by hyperammonemia; however, we recently reported that ammonia increases intracellular levels of BCAA and exerts toxic effects on astrocytes.

Objectives: This follow-up study was designed to confirm the direct effects of BCAA on human astrocytes and clarify their underlying mechanisms using metabolome analysis and evaluation of associated signaling.

Evidence-based clinical practice guidelines for peptic ulcer disease 2020.

The Japanese Society of Gastroenterology (JSGE) revised the third edition of evidence-based clinical practice guidelines for peptic ulcer disease in 2020 and created an English version. The revised guidelines consist of nine items: epidemiology, hemorrhagic gastric and duodenal ulcers, Helicobacter pylori (H. pylori) eradication therapy, non-eradication therapy, drug-induced ulcers, non-H.

Detection of microstructural white matter alterations in functional gastrointestinal disorders assessed by diffusion kurtosis imaging.

Background And Aim: We evaluated whether diffusion kurtosis and tensor imaging (DKI/DTI) could reveal microstructural alterations in the brains of patients with functional gastrointestinal disorders (FGIDs), and whether imaging findings were correlated with health-related quality of life (HRQOL).

Methods: Twelve patients with FGIDs fulfilling the Rome IV criteria, and seven healthy controls were examined using a 3 T magnetic resonance (MR) scanner. Tract-based spatial statistics and regions of interest analyses were performed to compare the mean kurtosis (MK), fractional anisotropy (FA), and mean diffusivity (MD) between patients with FGIDs versus controls.

Radiation Esophagitis in a Patient with Oral Carcinoma and Bone Metastasis.

Radiation esophagitis requiring endoscopic evaluation occurs quite rarely, affecting <1% of patients undergoing radiation treatment. Acute radiation esophagitis develops within 3 weeks of radiation therapy. We describe herein a case of radiation esophagitis in a patient with oral carcinoma with multiple general bone metastases.

Regulatory T cells in Crohn's disease following anti-TNF-α therapy.

Background And Aim: Anti-tumor necrosis factor alpha (TNF-α) therapy is an effective therapy for Crohn's disease (CD). We investigated FoxP3 and CD127 regulatory T cells (Tregs) before and after administration of anti-TNF-α therapy in CD.

Methods: Eight patients with active CD who had received anti-TNF-α antibodies were enrolled.

Hypopituitarism manifesting after invasive dental treatment in a patient with carcinoma of the tongue: a case report.

Background: The symptoms of hypopituitarism are not usually discussed in the clinical setting of oral surgery.

Case Presentation: We herein report a case of hypopituitarism that became evident after biopsy and extraction of several teeth in a 68-year-old man with tongue cancer. Three days after biopsy, the patient developed nausea and vomiting, and his serum sodium had fallen to 124 mEq/L.

Guidelines for standardizing cleansing and disinfection of gastrointestinal endoscopes.

As part of the activities toward standardizing endoscopy procedures, the Japan Gastroenterological Endoscopy Society has prepared guidelines for cleansing and disinfection of gastrointestinal endoscopes. The environment of gastrointestinal endoscopy differs between Japan and advanced Western countries. In advanced Western countries, gastrointestinal endoscopy is performed almost exclusively at specialized facilities, where strict provisions are observed for cleansing and disinfecting endoscopes.
