Cancer is a public health problem worldwide and a major cause of death or disability. Pain is one of the most common and feared symptoms in patients with cancer with marked impact on quality of life. According to the WHO analgesic ladder, opioids are the mainstay of cancer pain management, if well-accepted guidelines are systematically applied. ⋯ Since 1/3 of population will die from cancer (80 percent with severe pain in their final year of life) effective pain control remains an ongoing challenge. Opioid rotation may be useful in opening the therapeutic window and establishing a more advantageous analgesia/toxicity relationship. However, too much work is to be done to further individualize analgesic therapy for patients with cancer.

The authors hypothesized that Internal Medicine (IM) residents experience a lack of preparation, confidence, and reward when managing patients with chronic nonmalignant pain (CNMP) in their continuity clinic and that they exhibit deficiencies in CNMP management practices, particularly when opioids are prescribed. ⋯ The questionnaire indicated that IM residents lack preparation in managing CNMP, which results in lack of confidence and reward. The chart review revealed management practice deficiencies in risk assessment and prescription drug misuse monitoring. As a result, the authors have implemented curricular interventions, integrated a pain clinic within the continuity clinic, optimized residency program clinic scheduling, and developed tools for consistency in management practices.

Case Reports
Low-dose intrathecal naloxone to enhance intrathecal morphine analgesia: a case report.
Ultra low doses of opioid antagonists such as naloxone block excitatory opioid receptor pathways may paradoxically enhance morphine analgesia. This case study reports safety and efficacy of ultra low-dose intrathecal (IT) naloxone added to IT morphine for the treatment of severe refractory chronic low back pain. A 56-year-old man with a history of severe chronic low back pain (post-laminectomy syndrome) was evaluated. ⋯ There were no signs of adverse drug toxicity or hemodynamic compromise. An IT infusion of daily morphine 5 mg and naloxone 50 ng was started. Throughout the 3-year follow-up period, the patient maintained pain reduction of 60 to 80 percent, with a return to daily activities and no further hospitalizations.

Although opioid analgesics are effective therapeutic agents, gastrointestinal (GI) side effects represent a challenging consequence of treatment. In an elderly population, age-related physiological changes, such as decreased GI functioning and dehydration, may compound the adverse effects of opioids; therefore, appropriate prophylactic treatment, utilizing laxatives and/or acid suppressants, is particularly important in an elderly population. ⋯ Although laxatives are commonly recommended in patients taking opioids, only half of the older adults in Ontario who were dispensed an opioid also received a concomitant GI medication dispensing. As the elderly are more likely to develop opioid-induced constipation, the prophylactic use of laxatives and/or acid suppressant medications is often necessary to mitigate the side effects associated with their pain management.

This retrospective study reports a cohort of pediatric patients in whom subcutaneous dexmedetomidine was used to treat or prevent drug withdrawal following prolonged sedation in the Pediatric Intensive Care Unit setting. There were seven patients ranging in age from 6 months to 3.75 years and in weight from 4.8 to 17.7 kg. The dexmedetomidine infusion before switching to subcutaneous administration varied from 0.8 to 1.4 microg/kg/h. ⋯ Our preliminary experience suggests that dexmedetomidine can be administered by subcutaneous infusion without difficulty or alteration of its efficacy. This approach allows the administration of dexmedetomidine when peripheral venous access becomes problematic and may facilitate the removal of central venous catheters in patients recovering from critical illnesses. It also offers the possibility of using dexmedetomidine in settings where peripheral venous access is not available such as home palliative care.
