Article Synopsis
  • Visceral pain in the large bowel, a key symptom of irritable bowel syndrome (IBS), is largely triggered by mechanical distension of the colon and rectum, prompting patients to seek gastroenterological care.
  • This study aims to deepen understanding of how mechanical stimuli affect pain transmission in IBS through a detailed computational model that simulates the mechanical behavior of the mouse colorectum.
  • The model explores various hypotheses on how mechanical stress influences nerve signaling, enabling insights into the neural and biomechanical factors of IBS pain and guiding future research in this area.

Rationale And Objectives: Traditional medical student radiology experiences often lack interactivity and fail to replicate the clinical experience of being a radiologist. This study introduces SCRAPS, a novel simulation-based paradigm designed to improve the medical student experience and provide an active learning opportunity as part of their radiology rotation.

Materials And Methods: SCRAPS utilizes a consumer-grade laptop, common word processing software, a free to use PACS and resident instructors to place students in a simulated reading-room environment.

Henoch-Schönlein purpura (HSP) is a systemic vasculitis characterized by palpable purpura, arthralgia or arthritis, GI symptoms, and renal involvement. Superior mesenteric artery (SMA) syndrome, a rare condition, occurs when the third part of the duodenum is compressed between the aorta and the SMA, leading to upper intestinal obstruction. This case report describes the clinical presentation, diagnostic process, and management of an eight-year-old girl with HSP complicated by SMA syndrome.
