Comparative Study
Fluoroscopically assisted surgical treatments of spinal disorders: conceptus radiation doses and risks.
A series of anterior-posterior and lateral fluoroscopic exposures at 5 spinal levels were performed on anthropomorphic phantoms simulating the 3 trimesters of gestation. ⋯ Individual dose assessment is paramount in every pregnancy. Variations in fluoroscopy practices and gestational stage significantly affect fetal doses.

Comparative Study
Intradiscal thermal therapy does not stimulate biologic remodeling in an in vivo sheep model.
Thermal energy was delivered in vivo to ovine cervical discs and the postheating response was monitored over time. ⋯ While a high temperature thermal protocol had a detrimental effect on the disc, the effects of low temperature treatment were relatively minor. Thermal therapy did not stimulate significant biologic remodeling. Future studies should focus on the effects of low-dose therapy on tissue innervation and pro-inflammatory factor production.

Comparative Study
Work disability and costs caused by recurrence of low back pain: longer and more costly than in first episodes.
Retrospective analysis of workers' compensation (WC) claims data for nonspecific low back injuries (LBI) in a single jurisdiction. ⋯ Recurrences contributed disproportionately to the total burden of work-related nonspecific LBI, through both additional care seeking and work disability. Results imply that those who have recurrences may be an especially important target for secondary prevention efforts.

Review Meta Analysis
School-based interventions for spinal pain: a systematic review.
Systematic review. ⋯ The poor quality of the reviewed studies limits the conclusions that can be made regarding the effectiveness of school-based spinal health interventions.

Randomized Controlled Trial Comparative Study
Unilateral enucleation affects the laterality but not the incidence of scoliosis in pinealectomized chicken.
Randomized prospective study using an experimental scoliosis model in a pinealectomized chicken. ⋯ Unilateral visual impairment does not have a significant effect on the overall incidence and magnitude of scoliosis in the pinealectomized chicken. It does affect the laterality of the curves though, visually impaired subjects having a significantly higher likelihood of left thoracic curves, regardless of the side of blindness. It may be worthwhile to see if such an association is present in human beings as well.
