To study the pathogenesis of the pain of discography and the discogenic low back pain. ⋯ Findings indicate that the strip zone of granulation tissue with extensive innervation in the posterior part of the painful disc is the original site of the pain of discography and the discogenic low back pain. The strip zone of granulation tissue might originate from the injury and subsequent reparation of the margin of annulus fibrosus. The difference of the aging disc and painful disc which can not be differed each other on MRI is the formation of the strip zone of granulation tissue along tear histologically in posterior part of the painful disc.

A cross-sectional study of low back pain and its related aspects in a representative sample of Greek population. ⋯ According to the results of the study, low back pain is a frequent symptom in the general Greek population. Low back pain frequency and severity are associated with several socio-demographic factors, especially with age, sex, and kind of job.

Interventions for chronic low back pain (CLBP) often attempt to modify patients' levels of catastrophizing, their fear-avoidance beliefs, and their appraisals of control. Presumably, these interventions are based on the notion that changes in these cognitive factors are related to changes in measures of adjustment. The aim of the present study was to explore whether changes on these cognitive factors were related to changes in CLBP and disability. ⋯ The study found that changes in the cognitive factors were not significantly associated with changes in pain intensity. In contrast, reductions in fear-avoidance beliefs about work and physical activity, as well as increased perceptions of control over pain were uniquely related to reductions in disability, even after controlling for reductions in pain intensity, age and sex. The final model explained 71% of the variance in reductions in disability.

Randomized Controlled Trial Clinical Trial
Catastrophizing and internal pain control as mediators of outcome in the multidisciplinary treatment of chronic low back pain.
The aim of the present study was to examine (a) whether a cognitive-behavioral treatment (differentially) affects pain coping and cognition; and (b) whether changes in pain coping and cognition during treatment mediate treatment outcome. Participants in this randomized clinical trial were 148 patients with chronic low back pain attending a multidisciplinary treatment program consisting of operant-behavioral treatment plus cognitive coping skills training (N = 59) or group discussion (N = 58) or allocated to a waiting list control condition (N = 31). ⋯ Changes in catastrophizing and to a lesser degree in internal pain control mediated the reduction in level of depression and pain behavior following treatment. The use of behavioral and cognitive interventions aimed at decreasing catastrophizing thoughts about the consequences of pain and promoting internal expectations of pain control possibly constitute an important avenue of change irrespective of the type of treatment.
