Review of the effectiveness of capsaicin for painful cutaneous disorders and neural dysfunction.
Topical capsaicin is known to be a safe and effective pain management adjunct for rheumatoid arthritis, osteoarthritis, neuralgias, and diabetic neuropathy. However, studies and case reports in the literature have indicated that other conditions may also benefit from capsaicin: painful or itching cutaneous disorders from operations, injuries, or tumors; neural dysfunction; or inflammation of the airways and urinary tract. ⋯ Capsaicin is effective for psoriasis, pruritus, and cluster headache; it is often helpful for the itching and pain of postmastectomy pain syndrome, oral mucositis, cutaneous allergy, loin pain/hematuria syndrome, neck pain, amputation stump pain, and skin tumor; and it may be beneficial for neural dysfunction (detrusor hyperreflexia, reflex sympathetic dystrophy, and rhinopathy). A universal problem for many of the studies analyzed was the absence of a "burning placebo" such as camphor.

Burn injuries produce severe wound care pain that is ideally controlled on intensive burn care units with high-dosage intravenous opioid medications. We report a case illustrating the use of hypnosis for pain management when one opioid medication was ineffective. ⋯ This case illustrates that hypnosis can not only be used easily and quite appropriately in a busy medical intensive care unit environment, but that sometimes this treatment may be a very useful alternative when opioid pain medication proves to be dangerous and ineffective. This case also illustrates possible clinical implications both pain relief and side-effect profiles for opioid receptor specificity. Although this report does not provide data regarding hypnotic mechanisms, it is clear that with some patients nonopioid inhibitory mechanisms can be activated in a highly effective manner, that clinical context may be important for the activation of those pathways, and that those mechanisms may be accessed more easily than opioid mechanisms.

This report aims to present an orderly approach to the treatment of Chronic Regional Pain Syndrome (CRPS) types I and II through an algorithm. The central theme is functional restoration: a coordinated but progressive approach that introduces each of the treatment modalities needed to achieve both remission and rehabilitation. Reaching objective and measurable rehabilitation goals is an essential element. ⋯ This algorithm is a departure from the contemporary heterogeneous approach to treatment of patients with CRPS. The underlying principles are motivation, mobilization, and desensitization facilitated by the relief of pain and the use of pharmacologic and interventional procedures to treat specific signs and symptoms. Self-management techniques are emphasized, and functional rehabilitation is the key to the success of this algorithm.

Randomized Controlled Trial Comparative Study Clinical Trial
Symptoms of spinal stenosis do not improve after epidural steroid injection.
This study was carried out to evaluate the therapeutic effect of epidural steroid injection on pseudoclaudication in patients with lumbar degenerative spinal canal stenosis. ⋯ The results suggest that epidural steroid injection has no beneficial effect on the pseudoclaudication associated with spinal canal stenosis as compared with epidural block with a local anesthetic alone.

To determine to what extent stressful life events and psychological dysfunction play a role in the pathogenesis of Complex Regional Pain Syndrome type I (CRPS). ⋯ Stressful life events are more common in the CRPS group, which indicates that there may be a multiconditional model of CRPS. The experience of stressful life events besides trauma or surgery are risk factors, not causes, in such a model.
