[Timely colonoscopy leads to faster identification of bleeding diverticulum].

We conducted a retrospective study of the efficacy of a polyethylene glycol purge before colonoscopic examination in 110 patients with colonic diverticular bleeding. The patients' data were assessed for the timing of colonoscopy and the methods used to stop bleeding. The rate at which bleeding diverticula were identified was markedly higher when a purge was used than when it was not (28.

[Clinical pathway for bleeding peptic ulcers].

We devised and evaluated a clinical pathway (CP) protocol for patients with bleeding peptic ulcers (BPU). Patients without severe comorbidities, who had been diagnosed with BPU and who had undergone endoscopic treatment, were enrolled in our study. The CP adaptation rate for BPU patients was 78.

T-lymphocytes modulate the microvascular and inflammatory responses to intestinal ischemia-reperfusion.

Objective: The overall objective of this study was to define the contribution of T-lymphocytes to the microvascular and inflammatory responses of the intestine to ischemia/reperfusion (I/R).

Methods: The superior mesenteric artery of wild-type (WT) and SCID mice was occluded for 45 minutes, followed by 30 minutes or 6 hours of reperfusion. Intravital fluorescence microscopy was used to monitor the extravasation of FITC-labeled albumin or the adhesion of carboxy-fluorescein diacetate succinimidyl ester (CFSE)-labeled T-lymphocytes in mucosal venules of the postischemic intestine.
