ReviewManaging cluster headache with sphenopalatine ganglion stimulation: a review.
Cluster headache (CH) is a primary headache and considered as one of the worst pains known to man. The sphenopalatine ganglion (SPG) plays a pivotal role in cranial autonomic symptoms associated with pain. Lesioning procedures involving the SPG and experimental acute SPG stimulation have shown some degree of efficacy with regard to CH. ⋯ SPG stimulation appears as a promising innovative, efficient, and safe therapeutic solution for patients suffering from severe CH. It has shown its efficacy in aborting CH attacks compared to placebo stimulation, suggesting that it is particularly adapted for CH patients who are not sufficiently improved by abortive treatments such as sumatriptan and oxygen. However, further studies comparing SPG stimulation with standard abortive and/or preventive CH treatments will be necessary to define more precisely its place within the management of severe chronic and/or episodic CH.

Evaluation of pulsed electromagnetic field therapy for the treatment of chronic postoperative pain following lumbar surgery: a pilot, double-blind, randomized, sham-controlled clinical trial.
The incidence of chronic postoperative pain following lumbar spinal surgery has increased with the overall increase in the prevalence of lumbar surgery. This study was conducted to evaluate the analgesic effectiveness of pulsed electromagnetic field (PEMF) therapy in subjects with persistent pain following lumbar surgery. ⋯ PEMF therapy (42-μs pulse width) was associated with trends for a reduction in pain, compared to sham treatment. Secondary endpoints were consistent with an overall beneficial effect of the PEMF 42-μs pulse width device.

Presence of pain on three or more days of the week is associated with worse patient reported outcomes in adults with sickle cell disease.
While acute episodic pain is the hallmark of sickle cell disease (SCD), transition to chronic pain is a major cause of morbidity and impaired quality of life. One of the core diagnostic criteria used by Analgesic, Anesthetic, and Addiction Clinical Trial Translations Innovations Opportunities and Networks-American Pain Society Pain Taxonomy (AAPT) to define chronic SCD pain is the presence of pain on a "majority of days" in the past 6 months in one or more locations. The frequency characteristic of "majority of days" is adapted from the criteria of 15 days or more per month, used to define chronic migraine, but there are inadequate data to support this cutoff in SCD. ⋯ We did not find any difference in median PROMIS pain scores between adults aged ≤35 years compared with those aged ≥35 years. In linear regression models, after adjustment for age and sex, the presence of pain on 3 or more days a week was found to be associated with worse pain interference and anxiety. These data support the clinical relevance of the frequency characteristic of pain on a "majority of days" in the definition of chronic SCD pain, and provide the rationale for prospective studies to validate the clinical definition of chronic pain in SCD.

Safety and efficacy of subcutaneous tanezumab in patients with knee or hip osteoarthritis.
The objective of this study was to investigate the safety and efficacy of subcutaneous (SC) and intravenous (IV) tanezumab administration in osteoarthritis (OA) patients. ⋯ Preliminary results show similar efficacy and safety for both SC and IV administration of tanezumab based on the direct comparisons reported here and indirect comparisons with published results, confirming pharmacokinetic/pharmacodynamic modeling predictions.

Just how much does it cost? A cost study of chronic pain following cardiac surgery.
The study objective was to determine use of pain-related health care resources and associated direct and indirect costs over a two-year period in cardiac surgery patients who developed chronic post-surgical pain (CPSP). ⋯ Economic burden of chronic post-surgical pain may be substantial but few patients utilize resources. Health utilization and costs are associated with pain and psychological characteristics.
