To provide a mechanism-based acute pain management strategy for early phantom limb pain following traumatic amputations and to collect first evidence of its acute and potentially preventative effects on the formation and maintenance of phantom limb pain. The combination of continuous brachial plexus analgesia and prolonged block of N-methyl-D-aspartate (NMDA) receptors over 4 weeks aimed to attenuate peripheral and central sensitization, currently thought to be substantially involved in establishing and maintaining phantom limb pain. ⋯ The combination of long-term regional analgesia with prolonged block of NMDA receptors might be effective for treatment and prevention of phantom limb pain following traumatic amputations. The absence of clinically relevant side effects, together with maintained motor function suggests this treatment to be a promising preventive strategy for phantom limb pain following traumatic amputations.

Patients who do not improve after lumbar surgery may be given the nonspecific label of "failed back surgery syndrome (FBSS)." Since 1981, there has not been a quantitative assessment of the etiologies of FBSS despite major improvements in surgical techniques and diagnostic testing. ⋯ We were able to establish a predominant diagnosis in 94% of our patients. Foraminal stenosis remains the leading cause of FBSS, but painful discs are also common. Recurrent disc herniation is seen less often than in the past, and there is increased recognition of neuropathic pain. Knowledge of the potential causes of FBSS leads to a more efficient and cost-effective evaluation of these patients.

To quantify resource utilization and costs incurred for patients who received transdermal fentanyl as their first long-acting analgesic for non-malignant pain, and to compare these with utilization and costs for similar patients dispensed other long-acting oral opioids. ⋯ Users of fentanyl transdermal system and other long-acting opioids experienced essentially identical evolution of health services utilization and costs over a 2-year period. The choice of long-acting opioid analgesia does not appear to be a determinant of future medical costs.

The illness behavior questionnaire (IBQ) is a test battery developed by Pilowsky to detect what he has termed abnormal illness behavior, which includes malingering. The IBQ has been widely utilized in patients with chronic pain (PWCP). Clayer developed a 21-item scale out of the IBQ, which he termed the conscious exaggeration (CE) scale. He proposed that the CE scale could detect conscious deception, i.e., malingering. The purpose of the present study is to test the CE scale in PWCP alleged to have secondary gain and thereby at greater risk for poor pain treatment outcome. It was postulated that the CE scale should generate scores in these groups significantly different from a comparison group and should predict treatment outcome in the secondary gain groups. ⋯ PWCP characterized by the alleged secondary gain variables of Workers' compensation status, litigation, and having a lawyer did not differentially respond to the CE scale versus the comparison group. The CE scale, therefore, does not appear to be a valid instrument for identifying exaggeration in PWCP.

The purpose of this study was to assess the educational value and acceptability of a short CD-ROM course on cancer pain management given to third-year medical students at the University of Kentucky. ⋯ A short-course computer format program was developed by the authors to teach the basics of cancer pain management to medical students. A minority of students evaluated the program and agreed the material was clearly presented, improved knowledge of opioid analgesia, and was easy to use.
