Costs of providing infusion therapy for patients with inflammatory bowel disease in a hospital-based infusion center setting.

Aims: Inflammatory bowel disease (IBD) (e.g. ulcerative colitis [UC] and Crohn's disease [CD]) severely impacts patient quality-of-life.

Persistent second-degree atrioventricular block following adenosine infusion for nuclear stress testing.

The agents used for nuclear stress testing (NST) including adenosine, dobutamine, and dipyridamole, are generally well tolerated and the incidence of serious complications associated with their use in NST is relatively low. Adenosine possesses a potent inhibitory effect on the atrioventricular (AV) node and may induce a transient conduction defect which could result in first-, second-, or third-degree heart block in some patients. The use of the potent AV nodal blocker adenosine for nuclear stress testing in patients with evidence of underlying conduction system disease may result in serious complications.
