Spinal cord stimulation reduces pain of critical ischaemia in patients with severe inoperable coronary artery and peripheral vascular disease by increasing microvascular flow. Patients with cardiac pacemaker may be denied a spinal cord stimulator (SCS) implant because of the risk of compromising pacemaker function by inhibition or reversion to asynchronous noise-pacing mode. We describe the management of a patient with an SCS implant for lower limb ischaemia who required a pacemaker. We suggest that with modern pacemakers it is safe to implant a spinal cord stimulator simultaneously with a pacemaker provided adequate precautions are taken to prevent interdevice interference.

Factors influencing natural history and clinical course of pain in temporomandibular disorders (TMD) are largely unknown. Physical, psychological and behavioral data from a population-based epidemiologic study of TMD were examined in 234 cases of persons reporting TMD pain. The cases were assigned to one of five pain pattern groups based on changes in average TMD pain from baseline to 5-year follow-up: (i) remitted (49% of the sample), (ii) high-improvement (14%), (iii) low-improvement (9%), (iv) same (13%), and (v) worse (16%). ⋯ The three psychological variables, anxiety, depression, and somatization, displayed similar change patterns, but these patterns were distinctly different from those of the physical variables in that the remitted pain group was at the population mean at baseline for these psychological variables and remained there; significant improvement in psychological status was observed only in the pain group showing high improvement. The other three pain change groups exhibited elevated psychological distress scores at both baseline and 5 years. These results indicate that although the relationships among the course of pain, of physical variables, and of psychological variables are complicated, the 5-year outcome in pain is largely independent of readily discernible changes in clinical signs.

Nonacetylated salicylates are frequently used in the treatment of musculoskeletal complaints and pain management in older patients because of their possible lower gastrointestinal and renal toxicity as compared with other nonsteroidal anti-inflammatory agents. We report five patients with chronic salicylate intoxication seen at the Atlanta VA Medical Center. All charts of patients diagnosed with salicylate toxicity were reviewed, and cases with acute, intentional intoxication were excluded. ⋯ A significantly decreased urate level and a wide anion gap were consistent findings as well. Two of the patients improved after hydration and discontinuation of use of the drug, two required alkalinization of the urine, and one required dialysis. Clinicians need to be more aware of the potential toxicity, including life-threatening complications, with the use of salicylates, particularly in high risk populations such as elderly patients and patients with multiple medical problems.

A survey was carried out to provide "benchmark" data on current practices of in-hospital perioperative pain management. The 59-item survey questionnaire incorporated all key points contained in the Agency for Health Care Policy and Research and the American Society of Anesthesiologists published guidelines concerning institutional policies as well as practice patterns. The questionnaire was mailed to designated pain specialists in a sample of 400 hospitals that were systematically stratified by bed size and geographic region. ⋯ In general, large hospitals have a greater adherence to the recommendations of the guidelines than do smaller hospitals. No noteworthy variations in institutional policies or practice patterns were evident. These results provide comprehensive baseline data against which future developments in the field of perioperative pain management can be assessed.
