This prospective, consecutive series describes peripheral nerve stimulation (PNS) for treatment of severe reflex sympathetic dystrophy (RSD) or complex regional pain syndrome, in patients with symptoms entirely or mainly in the distribution of one major peripheral nerve. Plate-type electrodes were placed surgically on affected nerves and tested for 2 to 4(More)
The relative roles of spinal cord stimulation and the spinal infusion of opioids in the treatment of chronic, non-cancer lower body pain remains unclear. This report contains a retrospective analysis of patients with chronic lower body, neuropathic pain and treated over a 5 year period. Unilateral leg and/or buttock pain was treated initially with spinal(More)
In the past, pain control for chronic pain syndromes using narcotic infusion has been carried out primarily via the intrathecal (subarachnoid) route. This report presents one of the first large series of terminally ill cancer patients with intractable pain treated with continuous epidural morphine infusions by means of implanted pumps and epidural spinal(More)
It is now well demonstrated that several anticonvulsants have a role in the treatment of neuropathic pain and also in withdrawal from benzodiazepines, sedatives, and perhaps alcohol. Valproic acid, carbamazepine, gabapentin, clonazepam, and lamotrigine are appropriate treatments for neuropathic pain, effective to a degree dependent on the underlying(More)
Medical treatment of chronic cluster headaches (cluster headaches that occur frequently without remission) can be very difficult. In many patients, the pain remains severe despite all medication trials. For these patients, previous reports recommend radiofrequency trigeminal rhizotomy, which risks corneal anesthesia and subsequent corneal decompensation. As(More)
The concept of psychogenic pain has stimulated controversy in the field of pain medicine, not only regarding its prevalence, but indeed its very existence. Some would even hold that the term is fundamentally meaningless. Whether meaningless or not, it is often hated—by physicians in pain medicine whose patients have been harmed by not having been taken(More)
Intraspinal narcotic (usually intrathecal morphine) infusions with implanted pumps are increasingly used in patients with intractable chronic pain not caused by cancer. In some patients, pain control is difficult with infusions of morphine. Seven patients with diagnoses of arachnoiditis, epidural scarring, and/or vertebral body compression fracture were(More)
2008 marks the ninth published volume of Pain Medicine, born at the turn of the century into the brave new world of electronic academic publishing. These 8 years witnessed a revolution in the way our field creates, peer-reviews, and communicates new information in medical science and practice. Pain Medicine as a scholarly field and specialty practice has(More)
Chronic use of benzodiazepines, the most widely prescribed of all psychotropic medicines, may lead to severe symptoms of withdrawal when the drugs are discontinued. The authors describe two cases of benzodiazepine withdrawal accompanied by unusual muscle activity. The neurologic mechanism for the motor abnormalities appears to be marked disinhibition of(More)
