Approximately 5% of the patients referred to outpatient pain clinics suffer thoracic pain. Thoracic pain in this article is limited to thoracic radicular pain and pain originating from the thoracic facet joints. Thoracic radicular pain is characterized by radiating pain in the localized area of a nervus intercostalis. ⋯ However, extensive skills are required to perform this procedure above the level of Th7. This treatment should take place in specialized centers. For thoracic facet pain, radiofrequency treatment of the ramus medialis of the thoracic rami dorsales is recommended (2 C+).

Lumbosacral radicular pain is characterized by a radiating pain in one or more lumbar or sacral dermatomes; it may or may not be accompanied by other radicular irritation symptoms and/or symptoms of decreased function. The annual prevalence in the general population, described as low back pain with leg pain traveling below the knee, varied from 9.9% to 25%, which means that it is presumably the most commonly occurring form of neuropathic pain. The patient's history may give a suggestion of lumbosacral radicular pain. ⋯ For refractory lumbosacral radicular pain, adhesiolysis and epiduroscopy can be considered (2 B+/-), preferentially study-related. In patients with a therapy-resistant radicular pain in the context of a Failed Back Surgery Syndrome, spinal cord stimulation is recommended (2 A+). This treatment should be performed in specialized centers.

Review Randomized Controlled Trial Historical Article
Preliminary observations of a novel topical oil with analgesic properties for treatment of acute and chronic pain syndromes.
Essential oxygen oil (OxyRub from CreoMed Inc., Naples, FL, U.S.A.) is a novel topical analgesic currently commercially available in Europe and now available in the U.S.A. It represents an important alternative to other treatments (nonsteroidal anti-inflammatory drugs, acetaminophen, menthol, camphor) for managing mild to moderate acute and chronic pain. Several clinical trials of this oil will be reviewed. ⋯ Based on studies completed, essential oxygen oil has shown itself to be safe, has demonstrated positive analgesic effects for the treatment of acute and chronic pain, and has improved oxygen content in the skin as well as other dermatological parameters.

Review
The role of glia and the immune system in the development and maintenance of neuropathic pain.
Neuropathic pain refers to a variety of chronic pain conditions with differing underlying pathophysiologic mechanisms and origins. Recent studies indicate a communication between the immune system and the nervous system. A common underlying mechanism of neuropathic pain is the presence of inflammation at the site of the damaged or affected nerve(s). ⋯ Following peripheral nociceptive activation via nerve injury, microglia become activated and release pro-inflammatory cytokines such as tumor necrosis factor-alpha, interleukin-1beta, and interleukin-6, thereby initiating the pain process. Microglia propagate the neuroinflammation by recruiting other microglia and eventually activating nearby astrocytes, which prolongs the inflammatory state and leads to a chronic neuropathic pain condition. Our review focuses on the role of glia and the immune system in the development and maintenance of neuropathic pain.

Whiplash-associated disorders are comprised of a range of symptoms of which neck complaints and headaches are the most significant spine related. In the acute and sub-acute stage of the disorder, conservative treatment for minimally 6 months is recommended, active mobilization is slightly better than passive treatment. ⋯ The available evidence for injection of Botulinum toxin A (2 B-) and intra-articular corticosteroid injections (2 C-) supports a negative recommendation. Radiofrequency treatment of the ramus medialis (medial branch) of the ramus dorsalis is recommended (2 B+).
