Colonic Pseudolipomatosis: A Rare but Characteristic Endoscopic Condition.

BACKGROUND Colonic pseudolipomatosis (CP) can pose a diagnostic challenge due to its rare incidence and multiple presentations, most of them not very familiar to the endoscopist. Its etiology and pathogenesis have not been completely clarified. It can be related to mucosal iatrogenic injury caused during endoscopic examination or to chemical injury caused by residual disinfectants on the surface of the scope after cleansing.

A first look at the N- and O-glycosylation landscape in anuran skin secretions.

Amphibians secrete a complex array of molecules that shape their interactions with coinhabiting microorganisms and macroscopic predators. Glycans are a rapidly evolving and complex class of biomolecules implicated in intrinsic and extrinsic recognition events. Despite the numerous studies aiming at the biochemical characterization of anuran skin secretions, little is known about protein-linked oligosaccharides, their synthesis pathways, and their homing secreted glycoproteins.

Pneumoretroperitoneum and Sepsis After Transanal Endoscopic Resection of a Rectal Lateral Spreading Tumor.

Transanal endoscopic microsurgery is considered a safe, appropriate, and minimally invasive approach, and complications after endoscopic microsurgery are rare. We report a case of sepsis and pneumoretroperitoneum after resection of a rectal lateral spreading tumor. The patient presented with rectal mucous discharge.

IS DIGITAL RECTAL EXAM RELIABLE IN GRADING ANAL SPHINCTER DEFECTS?

Background: Anal sphincter tone is routinely assessed by digital rectal examination in patients with fecal incontinence, although its accuracy in detecting sphincter defects or separating competent from incompetent muscles has not been established.

Objective: In this setting, we aimed to evaluate the accuracy of digital rectal examination in grading anal defects in order to separate small from extensive cases as depicted on 3D endoanal ultrasound, using a scoring sphincter defect and correlate anal tone to anal pressures.

Methods: Women with fecal incontinence were divided into two groups: small or extensive defects according to the ultrasound scoring system.
