Meta Analysis
Efficacy of spinal cord stimulation: 10 years of experience in a pain centre in Belgium.
Spinal cord stimulation is a minimally invasive mode of treatment in the management of certain forms of chronic pain that do not respond to conventional pain therapy. Several authors have reported encouraging findings with this technique. Over a 10-year period in a single centre, 254 patients were subjected to a trial period of spinal cord stimulation with an externalized pulse generator. ⋯ The aim of this study was to evaluate the efficacy of an implanted spinal cord stimulation system in terms of pain relief and quality of life and to assess the accuracy of the patient selection criteria. The results of this study demonstrate a high success rate as evaluated by the patients' own assessments--68% of the patients rated the result of the treatment as excellent to good after an average follow-up of almost 4 years. The resumption of work by 31% of patients who had been working before the onset of pain supports these positive findings.

Complex regional pain syndromes (CRPS) are challenging neuropathic pain states quite difficult to comprehend and treat. Although not yet fully understood, advances are being made in the knowledge of the mechanisms involved with CRPS. Patients often present with incapacitating pain and loss of function. ⋯ Implantable devices can aid those patients with CRPS. While progress is being made in treating patients with CRPS, it is important to remember that the goals of care are always to: 1) perform a comprehensive diagnostic evaluation, 2) be prompt and aggressive in treatment interventions, 3) assess and reassess the patient's clinical and psychological status, 4) be consistently supportive, and 5) strive for the maximal amount of pain relief and functional improvement. In this review article, the current knowledge of the epidemiology, pathophysiology, diagnostic, and treatment methodologies of CRPS are discussed to provide the pain practitioner with essential and up-to-date guidelines for the management of CRPS.

This randomized clinical trial was designed to determine the effectiveness of therapeutic lumbar facet joint nerve blocks. Two hundred patients were evaluated with controlled diagnostic blocks for the presence of facet joint mediated pain. Eighty four patients, or 42% were determined to have lumbar facet joint mediated pain. ⋯ Cumulative significant relief with one to three injections was 100% up to 1 to 3 months, 82% for 4 to 6 months, 21% for 7 to 12 months, and 10% after 12 months, with a mean relief of 6.5 +/- 0.76 months. There was significant improvement noted in overall health status with improvement not only in pain relief, but also with physical, functional, and psychological status, as well as return-to-work status. In conclusion, the results of this study demonstrate that medial branch blocks with local anesthetic and Sarapin, with or without steroids, are a cost effective modality of treatment, resulting in improvement in pain status, physical status, psychological status, functional status and return to work.

Comparative Study
The management of chronic pain in Switzerland: a comparative survey of Swiss medical specialists treating chronic pain.
Chronic pain management by Swiss specialist physicians with the primary hypothesis that pain clinic practitioners conform better to good practice (interdisciplinarity, diagnostic/therapeutic routines, quality control, education) than other specialists treating chronic pain was surveyed. Management of all types of chronic pain by pain clinic practitioners and rheumatologists, oncologists or neurologists was compared via a mailed questionnaire survey (n=125/group). Two hundred and twenty-nine (46%) of 500 mailed questionnaires were returned with similar group return rates. ⋯ Pain clinic practitioners and oncologists bring particular-differing-skills to chronic pain management compared to rheumatologists and neurologists. Chronic pain management diversity may result from differences in malignant and benign pain, and its generally being provided by the speciality treating the underlying cause. This survey identifies targets for improvement in areas fundamental to good chronic pain practice: interdisciplinarity, diagnostic/therapeutic tools, quality management and education.

Randomized Controlled Trial Clinical Trial
Improving the quality of pain treatment by a tailored pain education programme for cancer patients in chronic pain.
Educational interventions, aiming to increase patients' knowledge and attitude regarding pain, can affect pain treatment. The purpose of this study was to evaluate the effects of a Pain Education Programme (PEP), on adequacy of pain treatment, and to describe characteristics predicting change in adequacy. The PEP consists of a multi-method approach in which patients are educated about the basic principles regarding pain, instructed how to report pain in a pain diary, how to communicate about pain, and how to contact healthcare providers. ⋯ Variables predicting an improvement in adequacy of pain treatment consisted of the PEP, the APMI score at baseline, patients' level of physical functioning, patients' level of social functioning, the extent of adherence to pain medication, patients' pain knowledge, and the amount of analgesics used. These findings suggest that quality of pain treatment in cancer patients with chronic pain can be enhanced by educating patients about pain and improving active participation in their own pain treatment. The benefit from the PEP, however, decreases slightly over time, pointing at a need for ongoing education.
