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.

Lumbar disc prolapse, protrusion, or extrusion account for less than 5% of all low back problems, but are the most common causes of nerve root pain and surgical interventions. The primary rationale for any form of surgery for disc prolapse is to relieve nerve root irritation or compression due to herniated disc material. The primary modality of treatment continues to be either open or microdiscectomy, but several alternative techniques including nucleoplasty, automated percutaneous discectomy, and laser discectomy have been described. There is a paucity of evidence for all decompression techniques, specifically alternative techniques including nucleoplasty. ⋯ This systematic review illustrates Level II-3 evidence for mechanical lumbar percutaneous disc decompression with nucleoplasty in treatment of leg pain. However, there is no evidence available in managing axial low back pain.

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.

Ethical and legal considerations in pain management typically relate to 2 issues. The first refers to pain management as a human right. The second involves the nature of the patient-physician relationship as it relates to pain management. ⋯ Absent a universal duty, no universal right exists. Pursuing pain management as a fundamental human right, although laudable, may place the power of the government in the middle of the patient-physician relationship. Despite apparent altruistic motives, attempts to define pain management as a basic human right could have unintended consequences, such as nationalization of medicine to ensure provision of pain management for all patients.

The intervertebral disc has been implicated as an etiology of chronic lumbar spine pain based on clinical, basic science, and epidemiological research. However, there is lack of consensus regarding the diagnosis and treatment of intervertebral disc disorders. Based on controlled evaluations, the lumbar intervertebral discs have been shown to be sources of chronic back pain without disc herniation in 26% to 39%. Lumbar provocation discography, which includes disc stimulation and morphological evaluation, is often used to distinguish a painful disc from other potential sources of pain. Despite the extensive literature, controversy continues about provocation lumbar discography. ⋯ Based on the current systematic review, lumbar provocation discography performed according to the IASP criteria with control disc (s) with minimum pain intensity of 7 of 10, or at least 70% reproduction of worst pain (i.e. worst spontaneous pain of 7 = 7 x 70% = 5) may be a useful tool for evaluating chronic lumbar discogenic pain. Discography is an important imaging and pain evaluation tool in identifying a subset of patients with chronic low back pain secondary to intervertebral disc disorders.
