Randomized Controlled Trial
Effect of Concomitant Pain Medications on Response to Pregabalin in Patients with Postherpetic Neuralgia or Spinal Cord Injury-Related Neuropathic Pain.
Patients with neuropathic pain (NeP) often receive combination therapy with multiple agents in the hopes of improving both pain and any comorbidities that may be present. While pregabalin is often recommended as a first-line treatment of NeP, few studies have examined the effects of concomitant medications on the efficacy of pregabalin. ⋯ The data presented here demonstrate that therapeutic response to pregabalin and the occurrence of adverse events in patients with NeP are generally unaffected by the concurrent use of other NeP medications.Trial Registration numbers: NCT00159666; NCT00301223; NCT00407745Key words: Pregabalin, neuropathic pain, pain-related sleep interference, concomitant medications, postherpetic neuralgia, spinal cord injury, efficacy, safety.

Chronic neck pain patients display functional impairments like decreased range of motion, decreased strength, and reduced sensorimotor function. In patients without structural damage, the reason for the persistence of pain is not well understood. Therefore, it is assumed that in chronic pain states, memory processes play an important role. ⋯ These findings are important not only to improve the understanding of the neural organization of maladaptive pain behavior but also to reconsider clinical evaluation and treatment strategies. The current results therefore suggest that treatment strategies have to take into account and exploit the context in which the movement is performed. Key words: Maladaptive pain behavior, pain memory, brain plasticity, motor control, neck pain, fMRI, action observation, motor imagery.

Chronic neck and upper extremity pain associated with cervical origin is common, and cervical interlaminar epidural steroid injections (CILESIs) are frequently used to manage the symptoms of cervical spinal disorders. However, CILESIs are associated with risks such as dural puncture and cord injury. ⋯ During CILESIs, a contralateral oblique (CLO) view at 60 degrees is superior to other angles for visualizing the epidural space when the needle tip is placed in the interlaminar space and within the spinous processes margin. When the needle tip is placed in the interlaminar space and lateral to the spinous processes, a CLO view at 50 degrees is most appropriate.Institutional Review Board (IRB) approval number: S2016-0390-0001Key words: Chronic neck pain, chronic upper extremity pain, cervical epidural injections, cervical interlaminar steroid injections, steroid, needle tip position, needle tip visualization, fluoroscopy, complication, contralateral oblique view.

Cord trauma is a risk with a cervical and thoracic interlaminar epidural approach to the epidural space. Intermittent lateral fluoroscopic imaging to detect needle depth is often cumbersome and may be difficult to interpret. In comparison, the contra-lateral oblique (CLO) fluoroscopic view is efficient and easy to interpret. ⋯ We conclude the CLO view provides an efficient and reliable method to visualize needle tip depth in relation to the epidural space. The close inter-observer agreement was possible with minimal physician instruction. Key words: Cervical interlaminar, cervical epidural, contra-lateral oblique, fluoroscopic imaging.

Transforaminal lumbar endoscopic discectomy is a minimally invasive spine surgery procedure performed principally for the treatment of lumbar herniated discs. Endoscopic spine surgeons around the world have noted how far patients will travel to undergo this minimally invasive spine surgery, but the actual distance patients travel has never been investigated. ⋯ Quality metrics in health care tend to be focused on how health care is delivered. Another health care metric that focuses more on what patients desire is presented here: how far patients will travel for innovative spine care.Key words: Endoscopic spine surgery, transforaminal, minimally invasive, travel, lumbar disc herniation.
