Confocal Endomicroscopy Intestinal Epithelial Barrier Abnormalities in Individuals Without Documented Gastro-Intestinal Disease.
United European Gastroenterol J
January 2025
Department of Gastroenterology, CHU Liège, Liège, Belgium.
Background And Aims: Probe-based confocal endomicroscopy (pCLE) allows real-time microscopic visualization of the intestinal mucosa surface layers. Despite remission achieved through anti-tumor necrosis factor or vedolizumab therapy, anomalies in the intestinal epithelial barrier are observed in inflammatory bowel disease (IBD) patients. Our study aimed to assess these abnormalities in non-IBD individuals and compare them with IBD patients in endoscopic remission to identify the associated factors.

Department of Pharmaceutical and Pharmacological Sciences, University of Padua, Padua, Italy.
Background And Purpose: Inflammatory bowel disease (IBD) patients display genetic polymorphisms in toll-like receptor 4 (TLR4) genes, contributing to dysregulate enteric nervous system (ENS) circuits with increased levels of 5-HT and alteration of the neuroimmune crosstalk. In this study, we investigated the impact of TLR4 signalling on mouse ENS dysfunction caused by dextran sulphate sodium (DSS)-induced ileitis.
Experimental Approach: Male C57BL/6J (wild-type [WT]) and TLR4 mice (10 ± 2 weeks old) received 2% DSS in drinking water for 5 days and then were switched to 3-day regular drinking water.
Hemorrhagic Shock Due to a Gastrointestinal Stromal Tumor in a Patient With Neurofibromatosis Type 1: A Case Report.

Trauma Institute, Saint Francis Health System, Tulsa, USA.
Gastrointestinal stromal tumors (GISTs), though rare, are associated with neurofibromatosis (NF) type 1 and may cause significant gastrointestinal bleeding. A 42-year-old male with NF1 presented with severe hematochezia and underwent initial non-contrast CT, which was negative for abnormalities. Subsequent endoscopies and PillCam studies also revealed no clear bleeding source.

Faculty of Medicine, School of Medicine, National Yang Ming Chiao Tung University, Taipei, Taiwan, ROC.
Background: Many studies have reported the renal outcomes and metabolic consequences after augmentation cystoplasty (AC), however few studies have discussed changes in renal tubular function. The aim of this study was to determine the prevalence of metabolic disturbances, evaluate renal tubular function and 24-hour urine chemistry to evaluate the association between metabolic alterations and urolithiasis after AC.
Methods: We investigated serum biochemistry, blood gas, and 24-hour urinary metabolic profile of children who underwent AC between January 2000 and December 2020.
Alterations in Ileal Secretory Cells of The DSS-Induced Colitis Model Mice.
Acta Histochem Cytochem
December 2024
Department of Anatomy, School of Medicine, University of Occupational and Environmental Health, 1-1, Iseigaoka, Yahatanishi, Kitakyushu, Fukuoka 807-8555, Japan.
Inflammatory bowel disease is triggered by abnormalities in epithelial barrier function and immunological responses, although its pathogenesis is poorly understood. The dextran sodium sulphate (DSS)-induced colitis model has been used to examine inflammation in the colon. Damage to mucosa primality occurs in the large intestine and scarcely in the small intestine.
