The present study aimed to investigate the effectiveness of a 3-week multimodal inpatient pain program for children and adolescents with chronic pain. ⋯ Results of the study are promising in at least 2 ways: (1) a multimodal inpatient program might stop the negative effects of chronic pain, disability, and emotional distress in children and adolescents, and (2) the exploration of clinical significance testing has demonstrated utility and can be applied to future effectiveness studies in pediatric pain.

On pathophysiologic grounds, fibromyalgia (FM) is characterized by a deficit in diffuse noxious inhibitory controls (DNIC), but the role of depressive symptoms on these mechanisms has not been investigated. We hypothesized that the deficit in pain inhibition would be more pronounced in FM patients with depressive symptoms (FM+D), relative to patients without such symptoms (FM-D). ⋯ We found that FM+D patients have a more pronounced deficit in pain inhibition as well increased clinical pain. As such, these results show the usefulness of combining psychologic factors and psychophysical measures to identify subgroups of FM patients. These results may have implications for future treatment of FM patients with and without comorbid depressive symptoms.

Thoracic spinal cord stimulation for neuropathic pain after spinal meningioma removal: a case report.
Spinal cord stimulation (SCS) is highly successful for treating neuropathic pain but its effect is limited for central origin pain caused by cord injury. The authors describe a case in which pain was successfully controlled by SCS implantation in a patient with intractable chronic neuropathic pain after T5 meningioma removal. The authors tried lead insertion over the T5 level passing through postoperative adhesions to produce adequate stimulation to the patient's painful areas fully enough without any complications. This case showed good response to SCS even though it was a central type of neuropathic pain by spinal cord injury.

The aim of the study was to evaluate whether or not there exists nociceptive and non-nociceptive hypersensitivity at latent myofascial trigger points (MTrPs). ⋯ These results confirm the existence of nociceptive hypersensitivity at latent MTrPs and provide the first evidence that there exists non-nociceptive hypersensitivity (allodynia) at latent MTrPs. Finally, the occurrence of referred muscle pain is associated with higher pain sensitivity at latent MTrPs.

This study aimed to provide a comprehensive profile of a representative sample of patients with acute low back pain drawn from the primary care setting. A secondary aim was to determine whether patient characteristics are associated with pain intensity or disability at the initial consultation. ⋯ In a representative sample of acute low back pain patients in primary care, we found that the profile included only a small proportion of patients with compensable low back pain. Those without compensation were more likely to remain at work despite low back pain. Psychologic and other patient characteristics were associated with pain intensity and level of disability at the initial consultation.
