Randomized Controlled Trial
Effect of fluoroscopically guided caudal epidural steroid or local anesthetic injections in the treatment of lumbar disc herniation and radiculitis: a randomized, controlled, double blind trial with a two-year follow-up.
Lumbar disc herniation and radiculitis are common elements of low back and lower extremity pain. Among minimally invasive treatments, epidural injections are one of the most commonly performed interventions. However, the literature is mixed about their effectiveness in managing low back and lower extremity pain. In general, individual studies and systematic reviews of epidural steroid injections have been hampered by their study design, baseline differences between treatment groups, inadequate sample sizes, highly controlled settings, lack of validated outcome measures, and the inability to confirm the injectate location because fluoroscopy was not used. ⋯ Caudal epidural injections of local anesthetic with or without steroids might be an effective therapy for patients with disc herniation or radiculitis. The present evidence illustrates the potential superiority of steroids compared with local anesthetic at two year follow up based on average relief per procedure.

Randomized Controlled Trial
Efficacy of intrathecally administered dexmedetomidine versus dexmedetomidine with fentanyl in patients undergoing major abdominal cancer surgery.
Most of the clinical experience gained in the use of intrathecal alpha-2- adrenoceptor agonists has been described with clonidine. Human studies using a combination of intrathecal dexmedetomidine and local anesthetics are lacking. ⋯ Dexmedetomidine 5 μg given intrathecally improves the quality and the duration of postoperative analgesia and also provides an analgesic sparing effect in patients undergoing major abdominal cancer surgery. Furthermore, the addition of intrathecal fentanyl 25 μg has no valuable clinical effect.

Randomized Controlled Trial
Occipital nerve stimulation for chronic migraine: a randomized trial.
Chronic migraine (CM) and medication overuse headache (MOH) are disabling conditions that may be only partially managed with conservative treatments. Occipital nerve stimulation (ONS) is an innovative treatment for headache disorders. ⋯ According to the results obtained, ONS appears to be a safe and effective treatment for carefully selected CM and MOH patients.

Randomized Controlled Trial
Fluoroscopic epidural injections in cervical spinal stenosis: preliminary results of a randomized, double-blind, active control trial.
Cervical spinal stenosis is a common disease that results in considerable morbidity and disability. There are multiple modalities of treatments, including surgical interventions and multiple interventional techniques including epidural injections. The literature on the effectiveness of cervical epidural steroids is sporadic. Emerging evidence for cervical interlaminar epidurals for various conditions in the cervical spine is positive; however, the effect of fluoroscopic epidural injections in cervical spinal stenosis has not been studied. ⋯ NCT01071369.

Randomized Controlled Trial Multicenter Study
Sensor-driven position-adaptive spinal cord stimulation for chronic pain.
Variation in the intensity of neurostimulation due to body position is a practical problem for many patients implanted with spinal cord stimulation (SCS) systems because positional changes may result in overstimulation or understimulation that leads to frequent need for compensatory manual programming adjustments. ⋯ NCT01106404.
