[Chronic low back pain in a Southern Brazilian adult population: prevalence and associated factors].
To identify the prevalence of chronic low back pain (CLBP) and examine factors associated with this condition in a Southern Brazilian adult population, a population-based cross-sectional study was conducted, including 3,182 subjects of both sexes, aged 20 years or over, living in the urban area of Pelotas, Rio Grande do Sul State. The questionnaire included socio-demographic, behavioral, and nutritional variables, as well as characterization of exposure to ergonomic factors in daily activities. ⋯ Prevalence of CLBP is important as it limits normal activities and increases the use of health care services. There may be differences in the ergonomic risk factors for CLBP and low back pain in general.

Case series. ⋯ The procedure may be less effective when performed by a variety of providers than suggested by initial case series performed by single providers or practices in work-related LBP cases. Provider self-referral and narcotic use before IDET are significant risk factors for poor outcomes. Randomized controlled trials are needed to determine whether there is a subset of patients with discogenic back pain who derive substantial and sustained benefit from this procedure.

Randomized Controlled Trial Multicenter Study Clinical Trial
Cost-effectiveness of lumbar fusion and nonsurgical treatment for chronic low back pain in the Swedish Lumbar Spine Study: a multicenter, randomized, controlled trial from the Swedish Lumbar Spine Study Group.
A cost-effectiveness study was performed from the societal and health care perspectives. ⋯ For both the society and the health care sectors, the 2-year costs for lumbar fusion was significantly higher compared with nonsurgical treatment but all treatment effects were significantly in favor of surgery. The probability of lumbar fusion being cost-effective increased with the value put on extra effect units gained by using surgery.
