Randomized Controlled Trial
Central adaptation of pain perception in response to rehabilitation of musculoskeletal pain: randomized controlled trial.
Understanding the mechanisms of long-standing musculoskeletal pain and adaptations in response to physical rehabilitation is important for developing optimal treatment strategies. The influence of central adaptations of pain perception in response to rehabilitation of musculoskeletal pain remains unclear. ⋯ Examiner-blinded, parallel-group randomized controlled trial with allocation concealment.

Review
Proposed physician payment schedule for 2013: guarded prognosis for interventional pain management.
As happens every year, on July 1, 2012, the Centers for Medicare and Medicaid Services issued a proposed policy and payment rate for services furnished under the Medicare physician fee schedule for 2013. The proposed rule would provide certified registered nurse anesthetists to practice independent interventional pain management. Other issues, though no less important, include a 27% sustainable growth rate formula cut in reimbursement, along with a 2% sequester, which could lead to a potential cut of 29%. ⋯ Since then, Congress has intervened on multiple occasions to prevent additional cuts from being imposed. In this manuscript, we will describe important proposed changes to the physician fee schedule. Additionally, the impact of multiple changes on interventional pain management will be briefly described.

Multicenter Study
Ziconotide adverse events in patients with cancer pain: a multicenter observational study of a slow titration, multidrug protocol.
Ziconotide is a new analgesic agent administered intrathecally. It is challenging to use and can induce several and sometimes serious adverse events. A low initial dosage followed by slow titration may reduce serious adverse events. ⋯ The rates of minor and moderate adverse events were consistent with previous reports. However, the rate of serious adverse events was substantially lower. Our study confirms the efficacy of intrathecal analgesia with ziconotide for relieving refractory cancer pain. These results indicate that multimodal intrathecal analgesia in patients with cancer pain should include ziconotide from the outset in order to provide time for subsequent slow titration.

Sensory and motor system dysfunctions have been documented in a proportion of patients with acute whiplash associated disorders (WAD). Sensorimotor incongruence may occur and hence, may explain pain and other sensations in the acute stage after the trauma. ⋯ Patients with acute WAD present an exacerbation of symptoms and additional sensations in response to visually mediated changes during action. These results indicate an altered perception of distorted visual feedback and suggest altered central sensorimotor nervous system processing in patients with acute WAD.

Owing to the anatomical difference between the far lateral herniation of the lumbar disc (FHLD) and the intraspinal herniation of lumbar disc (iHLD), the outcome of transforaminal epidural steroid injections (TFESI) in patients with FHLD seems to be different from that in patients with iHLD. However, few studies have evaluated the efficacy of TFESI in FHLD. ⋯ The current study suggests that an alternative needle placement technique for TFESI appears to be necessary for FHLD patients.
