Cross-sectional analysis of analgesic use by patients with low back pain (LBP). ⋯ With this health plan, a high proportion of patients with LBP had claims for opioids during 2001. The use of opioids by patients with LBP represents a major cost for the health plan, and is associated with specific patient characteristics and their use of other LBP services.

A prospective, interventional case series design. ⋯ In a sample of people from a Middle Eastern culture undergoing exercise intervention for LBP for which they are not receiving workers' compensation, the preintervention physical activity subscale of the FABQ is predictive of negative outcome when the observed scores are > or =29. Despite significant improvements in all variables after intervention, anticipated pain remained significantly higher than reported pain during physical performance testing but did not predict outcome.

Spinal ependymoma is a benign central nervous system tumor described as an intramedullary lesion more frequently located at the conus medullaris. It has been described exceptionally in the literature as an intradural extramedullary tumor. ⋯ All of the previously reported cases of spinal intradural extramedullary ependymomas carried out a benign course. The case we are reporting is the first one in which malignant transformation occurred. This tumor should be taken into account in the differential diagnosis of intradural extramedullary lesions. Moreover, close follow-up is recommended for this unusual location of ependymomas.

A cross-sectional survey was conducted using face-to-face interviews. ⋯ In comparison with other developing countries, point prevalence of LBP is higher in Turkey and approximates to prevalence estimates of LBP in developed countries. Smoking may be associated with both occurrence and severity of LBP. Although piety is not associated with having LBP, religious people are more likely to have restricted activity related to LBP.
