Hex Me If You Can.

HexMe consists of 189 tetrahedral meshes with tagged features and a workflow to generate them. The primary purpose of HexMe meshes is to enable consistent and practically meaningful evaluation of hexahedral meshing algorithms and related techniques, specifically regarding the correct meshing of specified feature points, curves, and surfaces. The tetrahedral meshes have been generated with Gmsh, starting from 63 computer-aided design (CAD) models from various databases.

[Collagen gastroenterocolitis].

Introduction: Collagenous gastroenterocolitis is a recently known rare cause of chronic diarrhoea, that raises numerous nosological and diagnostic problems.

Observation: A 41 year-old woman was hospitalised for severe diarrhoea, diagnosed as collagenous gastroenterocolitis. Gastroscopy and ileocolonoscopy were macroscopically normal, but a 20 to 40 microns thick sub-epithelial collagenous band was revealed in the gastric, duodenal and colic biopsies.

Changes in renal artery resistance after meal-induced splanchnic vasodilatation in cirrhotic patients.

Purpose: A relationship between vasomotor tone changes in mesenteric and renal vessels in cirrhotic patients has been suspected but remains controversial. The aim of this study was to assess by duplex Doppler sonography the changes in the circulatory resistance of the renal arteries and superior mesenteric artery (SMA) following meal-induced splanchnic vasodilatation.

Methods: Twenty-seven cirrhotic patients and 15 healthy volunteers with no hepatic or renal dysfunction were prospectively included in the study.

[Acute hepatitis due to ecstasy].

Background: Ecstasy is a synthetic amphetamine which causes a wide variety of adverse effects. Hepatic toxicity was only recently demonstrated but can be quite severe.

Case Report: A 27-year-old male with no past medical or surgical history developed jaundice without fever.
