The objectives of this study were to investigate the associations of key constructs of relationship quality (cohesion, consensus, and satisfaction) and perceived partner responses to pain behavior (e.g., solicitous and negative responses) with the outcomes of pain and disability in those with long-term low back pain, and to explore the role of the patient's depressive symptom mood state on those associations. ⋯ Depressive symptoms play a significant role in determining the associations between relationship quality, perceived partner reactions, and pain and disability. The relationship construct of consensus and perceived solicitous responses were associated with pain and disability. These findings illustrate the importance of social context and patient mood state on the outcomes for those with low back pain.

Clinical Trial
Pain processing in medication overuse headache: a functional magnetic resonance imaging (fMRI) study.
The primary aim was to investigate functional differences between medication overuse headache (MOH) patients and controls with the purpose of evaluating the presence of a global alteration in the processing of noxious stimuli throughout the pain matrix. The secondary aim was to investigate whether activations in MOH patients normalize after medication withdrawal, which would suggest a possible role of the pain matrix in headache chronification. ⋯ Our findings suggest that significant functional changes occur in the lateral pain pathway in MOH patients. These could result from different processes: 1) cortical down-regulation aimed at reducing painful input to the cortex; 2) activity-dependent plasticity induced by excessive painful input during migraine attacks; and 3) direct effect of medication overuse. At 6 months after withdrawal, activity in these regions normalized, suggesting that no irreversible changes occur due to medication overuse.

Comparative Study
Patient satisfaction with residents vs attending following fluoroscopy-guided pain injections.
Patient satisfaction has been the object of interest in health care for some time and is now increasingly used as the basis for quality management and improvement. This study compares patient satisfaction between residents and attending in a pain clinic setting following fluoroscopy-guided steroid injections. ⋯ Patients treated by residents are more likely to rate their experience as worse compared with the attending. However, majority of patients in both groups were satisfied in that they perceived their procedure as expected or better than expected.
