It has been helpful in our practice to separate somatic from sympathetic-mediated peripheral nerve pain. We would recommend application of the new nomenclature of type I complex regional pain (sympathetic dystrophy) and type II complex regional pain (causalgia) (see Table 1). We believe it is essential that both of these conditions be separated into their early and late phases and that the treatment alternatives be customized for the individual patient and the peripheral nerve involved. ⋯ The surgeon occasionally may be involved in the manipulation and pinning of contracted joints, as well as release of muscle or joint contractures, followed by a supervised program of early range of motion. Finally, it is important that both physician and surgeon serve as patient advocates when questions of workers' compensation intervene that could deter proper treatment programs or when the patient needs the encouragement and guidance to continue with treatments that don't always initially appear to have immediate results. Finally, requests to the surgeon to find an operative cure must be resisted while continued psychological encouragement is provided.

The weight of available evidence suggests that reflex sympathetic dystrophy (RSD) is a complex clinical entity that (1) occurs predominantly in young adult women; (2) has five clinical types but presents most frequently as minor traumatic dystrophy; (3) has primary signs and symptoms (e.g., pain, edema, stiffness, and discoloration) that are expressed highly in each clinical type, whereas secondary signs and symptoms are variable; (4) responds well to treatment, regardless of its clinical type; and (5) is managed best when treatment is started early. It can be concluded that RSD is a multifaceted disease that responds well when managed with a multimodal treatment program aimed at the various interacting components of the disorder. The recognition and documentation of the variation of the clinical features of RSD may allow for its earlier diagnosis and treatment and thus significantly improve the chances for a successful outcome.

The management of chronic pain of spinal origin continues to represent a challenge for neurosurgeons. Spinal cord stimulation for chronic intractable pain is an effective therapy in approximately 50% of patients. The present study uses a novel imaging approach, functional magnetic resonance imaging (fMRI), to examine the central effects of spinal cord stimulation. ⋯ This report is the first to describe the cerebral effects of exogenous spinal cord stimulation with fMRI. fMRI allows for the objective examination of the effects of DCS and may provide an objective means of evaluating the efficacy of DCS as a therapy for intractable pain of spinal origin.

Opiates remain the most common form of analgesic therapy in the burn patient today. Because of increased opiate requirements, optimal relief of burn pain continues to be a problem for these patients. The purpose of this article is to summarize those alternative pain control methods that appear in the literature. ⋯ Ketamine has been extensively used during burn dressing changes but its psychological side-effects have limited its use. Clonidine, however, has shown promise in reducing pain without causing pruritus or respiratory depression. Other forms such as transcutaneous electrical nerve stimulation (TENS), psychological techniques, topical and systemic local anaesthetics are also useful adjuncts.

The aim of this investigation was to study the effect of electrical stimulation on nociceptive responses within the lumbar levels of the rat spinal cord. ⋯ The results demonstrate that two modes of train electrical stimulation can produce two patterns of fast-onset (within milliseconds), short-duration (within 20 seconds) inhibition of field potentials in the spinal cord. These results provide evidence that noxious heat-related impulses are modulated by the presence of specific electrical stimulation. The clinical application of transcutaneous electrical nerve stimulation to block pain is supported.
