BACKGROUND: Treatment of dysplastic Barrett's oesophagus prevents progression to adenocarcinoma; however, the optimal diagnostic strategy for Barrett's oesophagus is unclear. The Cytosponge-trefoil factor 3 (TFF3) is a non-endoscopic test for Barrett's oesophagus. The aim of this study was to investigate whether offering this test to patients on medication for gastro-oesophageal reflux would increase the detection of Barrett's oesophagus compared with standard management. METHODS: This multicentre, pragmatic, randomised controlled trial was done in 109 socio-demographically diverse general practice clinics in England...

A fast, non-invasive, high-performance liquid chromatographic screening method with electrospray ionization mass spectrometric detection was developed for the analysis of three major glycine-conjugated bile acids in human saliva. Using a mobile phase composed of 80% methanol and 0.1% formic acid, glycocholic, glycodeoxycholic, and glycochenodeoxycholic acids were separated in less than 4 minutes with sensitivity in the low nM range. Bile acids are thought to contribute to the pathology of various complications in gastroesophageal reflux disease, for instance, Barrett's esophagus, which may eventually lead to esophageal carcinoma...

In the gastroenterology field, the impact of artificial intelligence was investigated for the purposes of diagnostics, risk stratification of patients, improvement in quality of endoscopic procedures and early detection of neoplastic diseases, implementation of the best treatment strategy, and optimization of patient prognosis. Computer-assisted diagnostic systems to evaluate upper endoscopy images have recently emerged as a supporting tool in endoscopy due to the risks of misdiagnosis related to standard endoscopy and different expertise levels of endoscopists, time-consuming procedures, lack of availability of advanced procedures, increasing workloads, and development of endoscopic mass screening programs...

BACKGROUND: Radiofrequency ablation (RFA) is an effective treatment for dysplastic Barrett's esophagus (BE), but recurrence can occur after initial response. Currently there is uncertainty about how to best define histological remission. A DNA methylation panel on esophageal samples was previously shown to have high diagnostic accuracy for BE. We aimed to investigate this biomarker panel in the assessment of response to RFA treatment. METHODS: We retrospectively analyzed esophageal and gastroesophageal junction (GEJ) biopsies from patients with BE before and after RFA treatment...

Volumetric laser endomicroscopy (VLE) has been shown to improve detection of early neoplasia in Barrett's esophagus (BE). However, diagnostic performance using histopathology-correlated VLE regions of interest (ROIs) has not been adequately studied. We evaluated the diagnostic accuracy of VLE assessors for identification of early BE neoplasia in histopathology-correlated VLE ROIs. In total, 191 ROIs (120 nondysplastic and 71 neoplastic) from 50 BE patients were evaluated in a random order using a web-based module...

Gastroesophageal reflux disease (GERD) is a complex disorder with heterogeneous symptoms and a multifaceted pathogenetic basis, which prevent a simple diagnostic algorithm or any categorical classification. Clinical history, questionnaires and response to proton pump inhibitor (PPI) therapy are insufficient tools to make a conclusive diagnosis of GERD and further investigations are frequently required. The Lyon Consensus goes beyond the previous classifications and defines endoscopic and functional parameters able to establish the presence of GERD...

We report an unusual case of Barrett's esophagus with prominent intramucosal Russell bodies, also known as Russell body Barrett's esophagus. We present this case to emphasize the importance of recognizing this unusual entity. It also represents a potential diagnostic pitfall because the distended plasma cells may be mistaken for signet ring cells of gastric adenocarcinoma or low-grade lymphoma. Hence, an awareness of this entity is important to avoid diagnostic confusion.

ALA-mediated Photodynamic Therapy (ALA-PDT) is one of the most promising fields in Photodynamic therapy (PDT) research for cancer treatment. 5-aminolaevulinic acid (ALA) is the prodrug of the photosensitiser Protoporphyrin IX (PpIX). After ALA administration, cells generate PpIX through the haem biosynthetic pathway. Although the exact reasons for ALA/PpIX selectivity are unknown, it is believed that due to the special regulation of haem enzymes, PpIX is accumulated in the tumours. Both ALA and its derivative ALA Methyl ester, are mainly used in dermatology...

INTRODUCTION: Autoantibody tests are commonly ordered when screening for rheumatic diseases. Rheumatoid factor (RF) and antinuclear antibody (ANA) have low positive predictive values in general practice. Overuse of diagnostic tests can result in an increase in unnecessary referrals, patient anxiety, and further costs. OBJECTIVE: The objective was to evaluate the utilization patterns, appropriateness, and associated costs of tests including ANA, extractable nuclear antibodies (ENA), anti-double stranded DNA (anti-dsDNA), RF, and HLA-B27 in patients referred to rheumatologists...

Orthopedic implant hypersensitivity reactions (IHRs) are known to occur but are uncommon. Clinical presentations include local and generalized cutaneous reactions and noncutaneous complications. Pathogenesis traditionally was believed a type IV delayed hypersensitivity reaction, but there is evidence that innate immunity plays a role. Orthopedic implants are made predominantly of metals, and nonmetal components, such as bone cement, plastics, and ceramics, also may be utilized. Several diagnostic tests are available, and patch testing is considered the gold standard...

Sacroiliac (SI) joint pathology has been an increasingly discussed pathology as a potential etiology for significant low back and lower extremity pain. While patient history and examination maneuvers can assist with identifying the SI joint as a potential cause of pain, an intra-articular SI joint injection is critical to properly diagnose the SI joint as a clinically relevant pain generator. In addition to the diagnostic information from the injection, SI joint intra-articular injections can be performed for therapeutic benefit as part of a multi-modal, conservative treatment approach for SI joint pathology...
