[Role of cognitive pain coping strategies for depression in chronic back pain. Path analysis of patients in primary care].
The concurrent occurrence of chronic pain syndromes and depressive symptoms is a commonly observed phenomenon.The aim of the present study was to illuminate the mediating role of specific cognitive pain coping strategies as a connective link between pain and depression. ⋯ The results give further support for the cognitive mediation hypothesis and enhance it by pointing out the role of specific pain-related cognitive appraisals.

Studies with (sub) acute back pain patients show that negative expectancies predict pain and disability at a one-year follow up. Yet, it is not clear how expectations relate to other factors in the development of chronic disability such as pain and fear. This study investigates the relationship between expectations, pain-related fear and pain and studies how these variables are related to the development of chronic pain and disability. ⋯ In conclusion, expectancy, negative affect and fear avoidance beliefs are interrelated constructs that have predictive value for future pain and disability. Clinically, it can be helpful to inquire about beliefs, expectancy and distress as an indication of risk as well as to guide intervention. However, the strong interrelations between the variables call for precaution in treating them as if they were separate entities existing in reality.

We report a case of bone pain associated with primary hyperparathyroidism in a patient with sickle cell disease. A 17-year-old girl with sickle cell disease (SS phenotype) was seen for bilateral knee and back pain. She had had recurrent severe vaso-occlusive crises and acute chest syndrome in the course of her disease. ⋯ There is no known association between sickle cell disease and primary hyperparathyroidism, and this case is most probably a random occurrence. However, as emphasized by this case report, pain may also be a harbinger of other disease processes in sickle cell disease. Because management may vary, we suggest that care providers consider the diagnosis of vaso-occlusive crisis as the diagnosis of exclusion and that other etiologies for pain be envisaged in this patient population, especially in the presence of prolonged pain or unusual clinical, radiologic, or biological findings.

This study examined the role of work-related, psychosocial and psychological factors in predicting functional and social disability in working employees. In a cross-sectional design, 890 working employees (reporting at least 1 day of back pain during the past year) completed self-report measures of back pain, disability, pain-related fear, negative and positive affectivity, job satisfaction, job stress and physical work load. Regression analyses revealed that pain intensity was a strong predictor of functional (beta = .69, p < .001) and social disability (beta = .67, p < .001). ⋯ Further, (singular) mediation tests indicated that fear for (re)injury partially mediated the relation between pain intensity and disability, and between negative affectivity and disability. Finally, path analyses revealed both fear and pain intensity as mediators between negative affectivity and disability. Overall, our findings point at the relevance of the cognitive-behavioral model of avoidance in occupational settings.

Clinical TrialLumbar total disc replacement using ProDisc II: a prospective study with a 2-year minimum follow-up.
A lumbar total disc replacement (TDR) is believed to be a promising substitute in the surgical treatment for lumbar degenerative disc disease. The purpose of this study is to report the clinical and radiographic outcomes of 36 consecutive patients who underwent lumbar TDR using ProDisc II, and the factors associated with a better clinical outcome after a 2-year minimum follow-up. At the time of the latest follow-up, the success rate was 94% of 36 patients according to the criteria of the US Food and Drug Administration. ⋯ Statistical analysis showed that the factors associated with a better clinical outcome were single level, and a higher postoperative segmental ROM at the operative level. At a minimum follow-up of 2 years, the lumbar TDR using ProDisc II showed excellent clinical and radiographic outcomes without any significant complication. However, future efforts need to be directed toward the evaluation of a larger number of patients with longer follow-up.
