Opioids have been and continue to be used for the treatment of chronic pain. Evidence supports the notion that opioids can be safely administered in patients with chronic pain without the development of addiction or chemical dependency. However, over the past several years, concerns have arisen with respect to administration of opioids for the treatment of chronic pain, particularly non-cancer pain. ⋯ Tolerance is a necessary condition for OIH but the converse is not necessarily true. Office-based detoxification, reduction of opioid dose, opioid rotation, and the use of specific NMDA receptor antagonists are all viable treatment options for OIH. The role of sublingual buprenorphine appears to be an attractive, simple option for the treatment of OIH and is particularly advantageous for a busy interventional pain practice.

Review
Systematic review of percutaneous lumbar mechanical disc decompression utilizing Dekompressor.
In recent years, a number of minimally invasive nuclear decompression techniques for lumbar disc prolapse, protrusion, and/or herniation have been introduced, including the Dekompressor a device utilizing an Archimedes screw. The primary goal of the surgical treatment of nerve root compression from a disc protrusion continues to be the relief of compression by removing the herniated nuclear material with open discectomy. However, poor results have been reported for contained disc herniations with open surgical interventions. The results with several alternative techniques including the Dekompressor, automated percutaneous discectomy, and laser discectomy have been described, but are not convincing. There is a paucity of evidence for all decompression techniques. ⋯ This systematic review illustrates Level III evidence for mechanical percutaneous disc decompression procedures with the high RPM device or Dekompressor.

Diagnosis is a critical component of health care. The world of diagnostic tests is highly dynamic. New tests are developed at a fast pace and technology of existing tests is continuously being improved. ⋯ Interventional techniques as a diagnostic tool in painful conditions is important due to multiple challenging clinical situations, which include the purely subjective nature of pain and underdetermined and uncertain pathophysiology in most painful spinal conditions. Precision diagnostic blocks are used to clarify these challenging clinical situations in order to determine the pathophysiology of clinical pain, the site of nociception, and the pathway of afferent neural signals. Part 5 of evidence-based medicine (EBM) in interventional pain management describes the various aspects of diagnostic accuracy studies.

Case Reports
Serial stellate ganglion blocks for intractable postherpetic itching in a pediatric patient: a case report.
While intractable itching may be rarely associated with postherpetic neuralgia, it can have catastrophic complications if present. ⋯ The use of serial stellate ganglion blocks may be a treatment option for patients with intractable itching and postherpertic neuralgia of the neck and arm region. This technique may lead to more permanent solutions such as pulse radiofrequency lesion or chemical neurolysis of sympathetic ganglions for postherpetic itch.

Since the descriptions by Mixter and Barr of open surgical treatment for rupture of the intervertebral disc in 1934, open surgical procedures have become a common practice. Disc herniations have been reported as being contained and non-contained. The results of open surgical discectomy for contained disc herniation have been poor. Consequently, several alternative techniques have been developed which are minimally invasive including percutaneous laser disc decompression. ⋯ This systematic review illustrates Level II-2 evidence for percutaneous laser disc decompression which is equivalent to automated percutaneous lumbar disc decompression.
