Imaging features of therapeutic drug-induced musculoskeletal abnormalities.

Increasing use of a wide variety of therapeutic drugs with known musculoskeletal side-effect profiles necessitates a rigorous understanding and approach when evaluating imaging features suggestive of drug-induced musculoskeletal abnormalities. The etiology of such abnormalities is diverse, and the clinical and imaging manifestations may be nonspecific. The recognition of adverse effects depends, first, on the physician's vigilant review of clinical information for relevant drug history and indicative signs, and second, on the radiologist's ability to detect musculoskeletal changes consistent with known potential effects of specific drugs.

Assistance of colorectal stent insertion by sphincterotome.

Purpose: Palliation of patients with unresectable colorectal carcinoma is an effective treatment and technical failure is undesirable. Insertion of colorectal stent using a combined radiologic and colonoscopic technique may be technically limited by the ability to negotiate tortuous bends, particularly if the bowel is fixed.

Methods: We used a through scope sphincterotome, which improved the ability to traverse difficult strictures.

Minimizing postcolonoscopy abdominal pain by using CO(2) insufflation: a prospective, randomized, double blind, controlled trial evaluating a new commercially available CO(2) delivery system.

Background: Abdominal pain after colonoscopy is a common, distressing symptom resulting from bowel distension by insufflated gas. CO(2), unlike air, is rapidly cleared from the colon by passive absorption. A commercially available CO(2) delivery system has only recently become available.
