Transient hepatic attenuation difference or fat sparing? Aberrant right gastric vein determining a pseudolesion at the border of the IInd/IIIrd liver segments. Review of developmental concepts.

The aberrant right gastric vein (ARGV) is a rare anatomical variation. It can be responsible for unexplained hyperdensities in the hepatic parenchyma on CT scans, also known as third inflow effects. We present two cases sharing similar vascular pattern and slightly different imagistic findings on ultrasound and computer-tomography performed studies.

Gluten Induces Subtle Histological Changes in Duodenal Mucosa of Patients with Non-Coeliac Gluten Sensitivity: A Multicentre Study.

Background: Histological changes induced by gluten in the duodenal mucosa of patients with non-coeliac gluten sensitivity (NCGS) are poorly defined. Objectives: To evaluate the structural and inflammatory features of NCGS compared to controls and coeliac disease (CeD) with milder enteropathy (Marsh I-II). Methods: Well-oriented biopsies of 262 control cases with normal gastroscopy and histologic findings, 261 CeD, and 175 NCGS biopsies from 9 contributing countries were examined.

Accuracy of a no-biopsy approach for the diagnosis of coeliac disease across different adult cohorts.

Objective: We aimed to determine the predictive capacity and diagnostic yield of a 10-fold increase in serum IgA antitissue transglutaminase (tTG) antibody levels for detecting small intestinal injury diagnostic of coeliac disease (CD) in adult patients.

Design: The study comprised three adult cohorts. Cohort 1: 740 patients assessed in the specialist CD clinic at a UK centre; cohort 2: 532 patients with low suspicion for CD referred for upper GI endoscopy at a UK centre; cohort 3: 145 patients with raised tTG titres from multiple international sites.

Helicobacter pylori prevalence and risk factors among children with celiac disease.

Background/aims: The relationship between Helicobacter pylori and celiac disease (CD) remains controversial. The aim of this study was to assess the prevalence and risk factors for H. pylori infection among children diagnosed with CD.

Proton pump inhibitors therapy and risk of Clostridium difficile infection: Systematic review and meta-analysis.

Aim: To perform a systematic review and meta-analysis on proton pump inhibitors (PPIs) therapy and the risk of infection (CDI). METHODS We conducted a systematic search of MEDLINE/PubMed and seven other databases through January 1990 to March 2017 for published studies that evaluated the association between PPIs and CDI. Adult case-control and cohort studies providing information on the association between PPI therapy and the development of CDI were included.
