Cardiopulmonary arrest following cervical epidural injection.

Epidural steroid injection is a common treatment for the management of pain in a wide variety of patients. It is generally well tolerated and perceived to have few side effects, with a low risk of serious complications. Only a handful of reports exist that describe life-threatening complications such as subdural hematoma, respiratory depression, vasovagal response, and pneumocephalus.

Differential roles of cardiomyocyte and macrophage peroxisome proliferator-activated receptor gamma in cardiac fibrosis.

Objective: Cardiac fibrosis is an important component of diabetic cardiomyopathy. Peroxisome proliferator-activated receptor gamma (PPARgamma) ligands repress proinflammatory gene expression, including that of osteopontin, a known contributor to the development of myocardial fibrosis. We thus investigated the hypothesis that PPARgamma ligands could attenuate cardiac fibrosis.
