Comparative StudyEfficacy of epidural injections of Kenalog and Celestone in the treatment of lower back pain.
Epidural corticosteroid injections have been used extensively to treat lower back pain, but the relative effectiveness of one corticosteroid versus another has never been reported in a large patient series. We retrospectively reviewed 597 patients who had epidural corticosteroid injections to determine any difference in Kenalog or Celestone efficacy. ⋯ The epidural injection of Celestone Soluspan and Kenalog reduced lower back and radicular pain in more than half the patients, although Kenalog reduced pain in a significantly larger number of patients than Celestone Soluspan at 1 and 2 weeks after injection.

Using superparamagnetic iron oxide-enhanced MRI to differentiate metastatic hepatic tumors and nonsolid benign lesions.
We evaluated the ability of superparamagnetic iron oxide (SPIO)-enhanced MRI to differentiate solid metastatic tumors and nonsolid benign lesions by clarifying the characteristic signal-intensity pattern of each lesion on SPIO-enhanced T2-weighted and heavily T1-weighted gradient-echo images. ⋯ When evaluating metastatic liver tumors on SPIO-enhanced MRI, we recommend that heavily T1- and T2-weighted gradient-echo images be obtained with our parameters to exclude hemangiomas or cysts.
