IgG4-related disease presenting with gastric outlet obstruction.

A woman in her 20s presented with 6 weeks of fever, persistent vomiting and 28% loss of body weight. Symptoms were refractory to treatment with antiemetics and broad spectrum antibiotics.Further investigation via oesophageogastroduedenoscopy revealed a large gastric ulcer and pyloric stricture, causing gastric outlet obstruction (GOO).

Exercise-Induced Ischemic Colitis From Home-Based High-Intensity Interval Training (HIIT).

The current case presents a male in his 40s without significant past medical, surgical, or family history. Hematochezia started immediately after one hour of high-intensity interval training (HIIT), which included free-weight exercises and a circuit training instructional video. Relevant investigations included negative stool cultures and flexible sigmoidoscopy showing ischemic colitis in the mid-sigmoid.

Coronary artery calcification on routine CT has prognostic and treatment implications for all ages.

Aims: Guidelines have recommended reporting coronary artery calcification (CAC) if present on chest CT imaging regardless of indication. This study assessed CAC prevalence, prognosis and the potential clinical impact of its reporting.

Methods: We performed a single-centre retrospective analysis (January-December 2015) of 1400 chest CTs (200 consecutive within each age group: <40, 40-49, 50-59, 60-69, 70-79, 80-89, ≥90).

Rates of Bile Acid Diarrhoea After Cholecystectomy: A Multicentre Audit.

Introduction: Bile acid diarrhoea (BAD) can occur due to disruption to the enterohepatic circulation, e.g. following cholecystectomy.

Minimal impact electro-injection of cells undergoing dynamic shape change reveals calpain activation.

The ability of neutrophils to rapidly change shape underlies their physiological functions of phagocytosis and spreading. A major problem in establishing the mechanism is that conventional microinjection of substances and indicators interferes with this dynamic cell behaviour. Here we show that electroinjection, a "no-touch" point-and-shoot means of introducing material into the cell, is sufficiently gentle to allow neutrophils to be injected whilst undergoing chemokinesis and spreading without disturbing cell shape change behaviour.
