Multicenter cohort study of patients with buried bumper syndrome treated endoscopically with a novel, dedicated device.

Background And Aims: Buried bumper syndrome (BBS) is a rare adverse event of percutaneous endoscopic gastrostomy (PEG) placement in which the internal bumper migrates through the stomal tract to become embedded within the gastric wall. Excessive tension between the internal and external bumpers, causing ischemic necrosis of the gastric wall, is believed to be the main etiologic factor. Several techniques for endoscopic management of BBS have been described using off-label devices.

Therapeutic resolution of focal, predominantly anastomotic Crohn's disease strictures using removable stents: outcomes from a single-center case series in the United Kingdom.

Background And Aims: Intestinal and anastomotic strictures in Crohn's disease (CD) produce considerable morbidity. The development of surgery-sparing, endoscopic modalities for stricture resolution is essential. Removable stent therapy is emerging as an efficacious and safe means of stricture resolution.

Unsedated percutaneous endoscopic gastrostomy insertion: a safe, effective, and well-tolerated method.

Background: Percutaneous endoscopic gastrostomy (PEG) tube insertion is an uncomfortable procedure that has traditionally required sedation. In some patients, PEG tube insertion can be postponed or is not possible due to the risk of sedation. This article is a retrospective case series of 10 patients who have undergone unsedated peroral PEG tube insertion in the past 4 years at Stafford Hospital in the United Kingdom.

Outbreak of hepatitis A in the injecting drug user and homeless populations in Bristol: control by a targeted vaccination programme and possible parenteral transmission.

Objective: To study the use of hepatitis A virus (HAV) vaccination in controlling an outbreak of HAV in inner-city Bristol among injecting drug users (IDUs). To study whether hepatitis C virus (HCV) and hepatitis B virus (HBV) co-infection increases morbidity.

Design: Community-based cohort study.

Glucocorticoid resistance - what is known?

It has become apparent in recent years that the glucocorticoid receptor is not a simple on/off switch, but instead orchestrates subtle and complex interactions between large numbers of proteins. This more sophisticated understanding awaits a unifying concept that will explain mechanisms of glucocorticoid resistance and allow new approaches to enhancing sensitivity.
