Multicenter Study Observational Study
Evaluation of the Effectiveness of Percutaneous Octapolar Leads in Pain Treatment with Spinal Cord Stimulation of Patients with Failed Back Surgery Syndrome During a 1-Year Follow-Up: A Prospective Multicenter International Study.
To evaluate the effectiveness and safety of percutaneous octapolar (8-contact) leads in spinal cord stimulation (SCS) treatment of failed back surgery syndrome (FBSS) patients who have not reached their therapy goals with other treatment interventions. ⋯ Use of percutaneous octapolar SCS leads gives significant long-term pain relief and improvement in quality of life and sleep in FBSS patients. The outcomes are better than reported on 4-contact leads and indicate that the progress in SCS technology that has taken place during the past decade correlates with therapy improvements.

Randomized Controlled Trial Multicenter Study
Efficacy and Safety of Once-Daily Extended-Release (ER) Hydrocodone in Individuals Previously Receiving ER Morphine for Chronic Pain.
This post hoc analysis examined the effectiveness and safety of hydrocodone bitartrate (HYD) in patients with moderate-to-severe chronic pain who were previously taking extended-release morphine (morphine ER) for pain management. ⋯ The results of this subgroup analysis suggest that rotation from morphine ER to once-daily HYD in patients with moderate-to-severe chronic pain maintains or improves pain relief and does not increase safety concerns.

Multicenter Study
A Shortened Version of the Suicide Cognitions Scale for Identifying Chronic Pain Patients at Risk for Suicide.
Research in psychiatric outpatient and inpatient populations supports the utility of the Suicide Cognitions Scale (SCS) as an indicator of current and future risk for suicidal thoughts and behaviors. Designed to assess suicide-specific thoughts and beliefs, the SCS has yet to be evaluated among chronic pain patients, a group with elevated risk for suicide. The purpose of the present study was to develop and test a shortened version of the SCS (the SCS-S). ⋯ Results support the reliability and validity of the SCS-S among chronic pain patients, and suggest the scale may be a useful method for identifying high-risk patients in medical settings.

Multicenter Study Clinical Trial
Efficacy, Safety, and Predictors of Intradiscal Methylene Blue Injection for Discogenic Low Back Pain: Results of a Multicenter Prospective Clinical Series.
Prospective clinical study of intradiscal methylene blue injection for the treatment of lumbar discogenic pain. ⋯ Our findings of 40% positive respondents, and no complications, give reason to set up a randomized, double-blind, placebo-controlled, trial.

Multicenter Study
Validation of the Short Form of the Brief Pain Inventory (BPI-SF) in Spanish Patients with Non-Cancer-Related Pain.
The Brief Pain Inventory (BPI) is a widely used pain measurement tool. There are 2 versions, the BPI Long Form (BPI-LF) and Short Form (BPI-SF), which share 2 core scales measuring pain severity and pain interference but which use different recall periods (24 hours vs. 1 week). To date, the BPI-SF has not been validated for use in Spain. ⋯ Substantial improvements were seen on both subscales after 3 months of treatment (ES of 1.76 for pain severity and 1.51 for pain interference). Recall period did not noticeably affect scores; ICCs (95% CI) between the long and short versions were 0.946 (0.938 to 0.954) and 0.929 (0.919 to 0.939) for the severity and interference subscales, respectively. The Spanish version of the BPI-SF is a valid and reliable instrument to measure pain severity and interference.
