Randomized Controlled Trial Multicenter Study Comparative Study Clinical Trial
Does it matter which exercise? A randomized control trial of exercise for low back pain.
Multicentered randomized controlled trial. ⋯ Consistent with prior evidence, a standardized mechanical assessment identified a large subgroup of LBP patients with a DP. Regardless of subjects' direction of preference, the response to contrasting exercise prescriptions was significantly different: exercises matching subjects' DP significantly and rapidly decreased pain and medication use and improved in all other outcomes. If repeatable, such subgroup validation has important implications for LBP management.

A review of the literature on disc nutrition. ⋯ Loss of nutrient supply can lead to cell death, loss of matrix production, and increase in matrix degradation and hence to disc degeneration.

The occurrence of anular tears and general disc degeneration of the lumbar spine was studied in relation to the lifetime frequency of back pain. ⋯ Anular degeneration of the lumbar discs appear earlier and are more clearly related to back pain than previously thought, most probably due to the better sensitivity of the BaSO4 discography method to detect tears.

Case Reports
Fenestration of vertebral artery at the craniovertebral junction in Down syndrome: a case report.
Case report of a Down syndrome patient with right vertebral artery fenestration and abnormalities of the craniovertebral junction. ⋯ Before corrective surgery of craniovertebral junction anomalies in patients with Down syndrome, the possibility of vertebral artery anomalies associated with abnormal craniovertebral junction anatomy should be considered. With preoperative 3-dimensional computed tomography angiography, we can precisely identify the anomalous vertebral artery and modify the surgical approach to reduce the possible risk of intraoperative vertebral artery injury in advance.

Secondary analysis of the 2000 Medical Expenditure Panel Survey (MEPS). OBJECTIVE.: To examine national prescription patterns of nonsteroidal anti-inflammatory drugs (NSAIDs) and muscle relaxants among individuals with back pain in the United States. ⋯ Neither traditional NSAIDs, nor COX-2 inhibitors, nor muscle relaxants dominated prescriptions for back pain. However, a small number of individual drugs were attributable to most of the prescriptions for traditional NSAIDs or muscle relaxants. The prescription of some of the medications demonstrated wide variations across different regions or different racial and educational groups. More studies are needed to understand the source of the variations and what constitutes optimal prescribing.
