Although previous research suggests women report more severe pain than men, evidence for sex-related differences in pain-related disability is conflicting. Also, the impact of psychological factors on sex differences in disability is uncertain. ⋯ Women report greater pain-related disability than do men, even after controlling for depression, anxiety, and other psychological factors. Pain management strategies that target functional disability may be particularly important in the treatment of women with pain.

New concerns have appeared recently in regard to the increasingly complex relationship between physicians and the pharmaceutical or devices industry. The American Academy of Pain Medicine (AAPM) Council on Ethics has discussed the issue, especially focusing on the implication of conflicts of interest for Pain Medicine, and published several recommendations for specific professional situations that the Pain Medicine physician may encounter.

Randomized Controlled Trial
A new muscle pain detection device to diagnose muscles as a source of back and/or neck pain.
Trigger point (TrPs) identification has become the mainstay of diagnosis for the treatment of Myofascial Pain Syndrome; however, manual pressure (MP) to identify TrPs by determining low-pressure pain threshold has low interrater reliability and may lack validity since it is done on inactive muscles. To elicit contractions and mimic an active muscle or movement that "causes" pain, a Muscle Pain Detection Device (MPDD) has been developed. A selected muscle is stimulated and painful muscles are precisely detected, allowing distinctions between primary and referred muscle pain as well as distinguishing other functional muscle pain thought to cause MPS. ⋯ Using the MPDD appears to be more valid and potentially more reliable than palpation to identify muscles causing regional pain that could benefit from injections.

The present study builds on research to model abusers' perceptions of particular analgesics' attractiveness for abuse and extends these methods to derive an estimate of attractiveness for abuse of a not-yet-marketed abuse-deterrent formulation (ADF) of a prescription opioid (Remoxy), Pain Therapeutics, Inc., San Mateo, CA, and King Pharmaceuticals, Inc., Bristol, TN). In a previous study, the Opioid Attractiveness Technology Scaling (OATS) method identified, from a drug abuser's point of view, the particular features of a prescription opioid relevant to its attractiveness for recreational use. A second online sample rated the extent to which these features applied to particular products they had actually used/abused. These data were used to model the abusers' overall preference for prescription opioids they had used/abused. ⋯ The OATS method shows promise for providing pre-marketing estimates of attractiveness for abuse of not-yet-marketed ADFs.

We report a case of central pain successfully treated by epidural placement of spinal cord stimulator electrodes. Neuromodulation of primary afferent fibers and the underlying dorsal root entry zone provided effective analgesia whereas traditional lead placement over the dorsal columns on a prior occasion had not been effective. The rationale for this technique based on current understanding of the mechanisms of central pain and the risk/benefit considerations are discussed. ⋯ Lateral-lead spinal cord stimulation may be effective for some central pain syndromes through a partial restoration of homeostatic small-fiber signaling. Neuroanatomical and physiological data in a larger population of patients will be required to predict the best responders to this therapeutic modality.
