Case ReportsManagement of severe pain due to lumbar disk protrusion.
Lumbar intervertebral disk protrusion can cause excruciating pain in severe cases, which can be exacerbated by activity such as sitting down and straining at stool. Acute sciatica due to disk rupture will improve within 1 to 3 months. ⋯ Severe cases can require opioid analgesia, however people taking opioids for pain relief frequently present with opioid-induced bowel dysfunction. The use of transforaminal steroid injections is a controversial issue and repeat steroid injections should be considered in light of the risk-benefit profile of the individual patient.

Implications of bariatric surgery on chronic pain and opioid use.
Questions from patients about pain conditions, pain treatment, and responses from authors are presented to help educate patients and make them effective self-advocates. The topics addressed in this report are implications of bariatric surgery or weight loss surgery on chronic pain and opioid use, what to expect with regards to pain control, and the need to change opioid dose after bariatric surgery.

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.

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.

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.
