To define patient-determined success criteria for fibromyalgia and back pain treatment across four outcome domains: pain, fatigue, emotional distress, interference with daily activities. ⋯ Results highlight the importance of assessing the patient's view of successful outcome. Both fibromyalgia and back pain patients appear to have stringent criteria for success that existing treatments are often unlikely to meet. Comparison across groups indicated fibromyalgia patients have higher usual levels of pain, fatigue, distress, and interference. Interestingly, fibromyalgia patients also require greater changes across domains in order to consider treatment successful, despite rating higher levels of pain, fatigue, distress, and interference as successful. Recognizing patients' success criteria and treatment expectations encourages discussion and development of individualized treatment goals, and wider implementation of individualized treatment for chronic-pain populations is encouraged.

A synovial sarcoma presented in the knee of a young woman 20 years after the onset of pain which was attributed to complex regional pain syndrome (CRPS). Was this a chance occurrence, or could there be any link between the two conditions? Did the pain itself and the persistent inflammatory and immunological response to pain contribute to the development of malignancy, or could the malignancy have been present subclinically for many years and have contributed to the ongoing pain syndrome? This case report looks into the diagnosis of synovial sarcoma and CRPS and the relationship between the neurogenic inflammation seen in CRPS and that seen in malignancies. The diagnosis of CRPS is a diagnosis of exclusion. Constant vigilance of patients with this unpleasant condition is necessary.

To assess demographic and clinical factors associated with celiac plexus neurolysis outcomes. ⋯ Celiac plexus neurolysis may provide intermediate pain relief to a significant percentage of cancer sufferers. Both careful selection of candidates based on clinical variables, and technical factors aimed at enhancing the specificity of blocks may lead to improved outcomes.

We used Andersen's behavioral model of healthcare utilization to assess the relationship between sociodemographic, physical and psychosocial factors, and Complementary and Alternative Medicine (CAM) use among chronic pain patients. Three practitioner-based alternative therapies were considered: acupuncture, biofeedback/relaxation training, and manipulation services. ⋯ This study identifies variable patterns of CAM usage based on sociodemographic and health factors in chronic pain patients. Overall, who uses CAM depends on the modality; however, education, pain severity, and pain duration are persistent correlates of CAM usage regardless of the therapy considered. We found that mental health, as measured by depressive symptoms, had no noticeable impact on CAM usage among chronic pain patients. The clinical, policy, and research implications of CAM use are discussed.

This study determined the antihyperalgesic effect of CNSB002, a sodium channel blocker with antioxidant properties given alone and in combinations with morphine in rat models of inflammatory and neuropathic pain. ⋯ The maximum antihyperalgesic effect achievable with nonsedating doses of morphine may be increased significantly when the drug is used in combination with CNSB002.
