Chronic cancer pain is often refractory and difficult to treat. Ketamine is a medication with evidence of efficacy in the treatment of chronic pain. ⋯ Despite limitations in the breadth and depth of data available, there is evidence that ketamine may be a viable option for treatment-refractory cancer pain.

The primary objective of this study was to measure prescribing compliance with the Veterans Affairs/Department of Defense treatment guidelines for chronic non-cancer pain (CNCP) in the primary care setting. We also determined the proportion of subjects who demonstrated aberrant drug-related behaviors (ADRBs) and the patient characteristics associated with them. ⋯ This article studied the prescribing practices of opioids in a primary care setting and can be used to enhance provider education regarding chronic pain guidelines.

To investigate whether bilateral deep tissue pressure hyperalgesia exists in individuals with unilateral thumb carpometacarpal osteoarthritis (CMC OA). ⋯ This study revealed bilateral localized pressure pain hypersensitivity over the hand in individuals with unilateral thumb CMC OA, suggesting spinal cord sensitization mechanisms in this population. Future studies should analyze the presence of widespread pressure pain sensitivity in patients with thumb CMC OA to further determine the presence of central sensitization mechanisms.

The purpose of the study was to systematically review the historical therapeutics for chronic pain care directed at the dorsal root ganglion (DRG) and to identify future trends and upcoming treatment strategies. ⋯ Despite a robust understanding of the DRG and its importance in acute nociception, as well as the development and maintenance of chronic pain, relatively poor evidence exists regarding current therapeutic strategies. Novel therapies like electrical and pharmacologic strategies are on the horizon, and more prospective study is required to better qualify the role of the DRG in chronic pain care.

Randomized Controlled Trial
Improving needle visualization by novice residents during an in-plane ultrasound nerve block simulation using an in-plane multiangle needle guide.
Ultrasound-guided regional anesthesia with in-plane needle approaches can be challenging due to difficult needle visualization. We hypothesized that an in-plane, multiangle needle guide can help reduce the time it takes novice regional anesthesiologists to perform a simulated ultrasound-guided nerve-targeting procedure and enhance the visualization of the needle. ⋯ A needle guide can help reduce the time needed to complete a simulated nerve targeting procedure and enhance needle visualization for the novice sonographer in a phantom gel simulation. There was no significant reduction in the number of needle passes or in improvement of target approximation noted.
