Randomized Controlled Trial Multicenter Study
The Reciprocal Effects of Pain Intensity and Activity Limitations: Implications for Outcomes Assessment in Clinical Trials.
To examine the reciprocal effects of pain intensity and limitations in physical functioning over time. ⋯ These analyses showed that a decrease in activity limitations results in a decrease in pain intensity. However, changes in pain intensity had no effect on subsequent activity limitations in the study sample. None of the 3 outcome variables emerged as being more responsive to treatment than the others.

Factors Associated With Outcome after Superior Hypogastric Plexus Neurolysis in Cancer Patients.
Superior hypogastric plexus neurolysis (SHP-N) has been shown in uncontrolled studies to provide intermediate-term benefit in a majority of patients with pain secondary to genitourinary, gynecologic, and colorectal cancers. The purpose of this is to determine factors associated with treatment outcome. ⋯ Selecting patients based on demographic and clinical variables may improve treatment outcomes for SHP-N. Larger, prospective studies are needed to confirm our results and better refine selection criteria better.

Long-term Results of Percutaneous Lumbar Decompression for LSS: Two-Year Outcomes.
The aim of this report was to evaluate the long-term effectiveness and safety of mild lumbar decompression for the treatment of neurogenic claudication associated with lumbar spinal stenosis. This technique uses a percutaneous dorsal approach to remove small portions of ligament and lamina, thereby restoring space and decompressing the spinal canal. ⋯ In this report of 2-year follow-up on 45 patients treated with mild percutaneous lumbar decompression, patients experienced statistically significant pain relief and improved functionality.

Construct and Predictive Validity of the Chronic Pain Grade in Workers With Chronic Work-related Upper-extremity Disorders.
To evaluate the ability of Chronic Pain Grade (CPG) questionnaire to predict upper-extremity physical disability, at-work disability, and work status in workers with chronic work-related upper-limb injuries. ⋯ CPG has low to moderate ability to predict 6-month work status in patients with chronic upper-extremity disorders. Both a lack of CPG and work transition variability may have contributed to this finding. Extension of the upper end of CPG range might be investigated as a means to increase discrimination at the upper end spectrum of chronic pain, which predominate the population of patients with chronic musculoskeletal disorders.

Randomized Controlled Trial Multicenter Study Comparative Study
Comparative study between 2 protocols for management of severe pain in patients with unresectable pancreatic cancer: one-year follow-up.
The efficacy of a celiac plexus block for the treatment of upper abdominal cancer-related pain has been documented. However, the effect of preprocedural pharmacological control of pain on its efficacy remains unknown. The researchers investigated the effect of first controlling severe pain with medications and then performing the celiac plexus block and compared the results with those obtained when the celiac block was performed first followed by pharmacotherapy for controlling severe pain; the impact on and duration of pain relief, effect on the quality of life, and analgesic requirements were analyzed. ⋯ Controlling severe pain with medication and then performing the celiac block seems to be more effective in controlling pain, reducing opioid consumption, and improving the quality of life of patients with pancreatic cancer compared with performing the celiac block at the beginning followed by pharmacotherapy for pain relief.
