Phantom pain is pain caused by elimination or interruption of sensory nerve impulses by destroying or injuring the sensory nerve fibers after amputation or deafferentation. The reported incidence of phantom limb pain after trauma, injury or peripheral vascular diseases is 60% to 80%. Over half the patients with phantom pain have stump pain as well. ⋯ Based on the available evidence some effect may be expected from drug treatment. When conservative treatment fails, pulsed radiofrequency treatment of the stump neuroma or of the spinal ganglion (DRG) or spinal cord stimulation could be considered (evidence score 0). These treatments should only be applied in a study design.

Pain, motor, and sensory deficits characterize patients with a traumatic lesion of the brachial plexus. Frequently, more severe injuries co-exist that require immediate surgical attention. Early rehabilitation and physical therapy are the cornerstones of treatment. ⋯ Surgical reconstruction is frequently advised when nerves are disrupted. The results, mostly from small historical reports, vary greatly. Neurostimulation may have an additional beneficial effect, especially if the pathophysiology of nociception and neuropathic pain becomes evident in these complex patients.

Herpes zoster pain and postherpetic neuralgia (PHN) particularly affect older persons. This literature review presents how quality of life is evaluated and the consequences of shingles and PHN on the quality of life of older persons. Although more than 150 articles have been published on herpes zoster and its consequences, specific studies focusing on the older population are needed, in several domains like epidemiology, preventive medicine, neuropsychology, and pharmacology.

With few exceptions, anesthesiologists have not received training in the use of immune modulating drugs (IMDs); but recent evidence suggests that such drugs may be effective in reducing chronic pain. We therefore wished to learn how anesthesiologists working in pain medicine might envisage the treatment of their patients with IMDs in the future. We expected that anesthesiologists would want to refer patients for treatment with IMDs to medical colleagues, such as oncologists or rheumatologists, with prior experience in using these drugs, rather than treat these patients within their own practice. ⋯ Contrary to what we had expected, we found that a majority of the respondents would administer IMDs within their own practice, after appropriate training. The overall response rates were 30% and 23%, respectively; therefore, no firm conclusions can be drawn as to the views of the majority of practicing pain specialists. Our findings may have implications for the planning of both health service delivery and training in pain medicine.
