Individuals seeking treatment for chronic pain in multidisciplinary pain management services are typically already on high doses of pain medications. This cross-sectional cohort study of patients with long-term chronic pain examined profiles of polypharmacy and pain medication-related harm exposure. ⋯ While treatment with multiple medications for synergistic or adjunctive effects may assist in medical management of chronic pain, this approach generates increased potential harm exposure. We show that the majority of detriment comes from medications other than opioids and highlight the importance of profiling all pain medications contributing to polypharmacy in clinical pain studies.

Pain is one of the most common and distressing symptoms in patients with cancer, with a high prevalence of 90%. Appropriate pain assessment is very important in managing cancer pain. ⋯ The use of a self-reporting pain assessment tool as a communication instrument provides an effective foundation for evaluating pain intensity in cancer pain management. A more individualized approach to patient education about pain management may improve patient outcome.

The attractiveness of opposites: agonists and antagonists.
Opioid-induced bowel dysfunction, of which constipation is the most common aspect, is a major limiting factor in the use of opioids for pain management. The availability of an oral, long-acting formulation of oxycodone and naloxone represents a highly significant development in pain management. The combination of an opioid analgesic with an opioid antagonist offers reliable pain control with a significant reduction in the burden of opioid-induced constipation.

Cough is a distressing symptom in advanced cancer. Opioids are used to relieve respiratory symptoms including dyspnea and cough. In addition to a central mechanism, opioids are thought to work peripherally via opioid receptors of the lung. Therefore, direct inhalation of morphine has been investigated in chronic lung disease or cancer. We report our experience of a nebulized form of morphine to control intractable cough in patients with advanced cancer. ⋯ Nebulized morphine was effective in controlling intractable cough due to cancer and it was convenient and safe.

Effect of buprenorphine on total intravenous anesthetic requirements during spine surgery.
Buprenorphine is a partial mu receptor agonist and kappa/delta antagonist commonly used for the treatment of opioid dependence or as an analgesic. It has a long plasma half-life and a high binding affinity for opioid receptors. This affinity is so high, that the effects are not easily antagonized by competitive antagonists, such as naloxone. ⋯ She had drastically reduced anesthetic requirements during this case, suggesting buprenorphine's profound effect on anesthetic dosing. This case report elegantly illustrates that discontinuation of buprenorphine is likely warranted for patients who present for major spine surgery, which necessitates the avoidance of volatile anesthetic and paralytic agents. The addition of ketamine may be necessary in patients maintained on buprenorphine in order to ensure a motionless surgical field.
