Some patients with chronic pain who are intolerant of or refractory to treatment with systemic analgesics may benefit from intrathecal therapy. Ziconotide is the first nonopioid analgesic approved by the United States Food and Drug Administration for intrathecal administration. Several randomized, double-blind, placebo-controlled clinical trials have demonstrated the efficacy and safety of ziconotide. ⋯ Efficacy can be assessed by an evaluation of changes in pain, functionality, and quality of life. Cognitive adverse events may be subtle; therefore, it is important that health care professionals not only monitor patients for signs and symptoms of cognitive adverse events, but also teach family members how to do the same. Careful patient assessment and monitoring can help optimize the potential benefit from treatment with ziconotide.

Although the experience of being believed is frequently alluded to in chronic pain literature, few studies have specifically explored this phenomenon and even fewer reviews have been offered. This narrative review sought to explore the wider social context in which individuals with chronic pain may experience disbelief toward their pain. Articles were obtained through a search of eight databases and a hand search of the references of full-text papers. ⋯ Finally, disbelief can lead to emotional distress. This can take the form of guilt, depression, and anger. Throughout the article, implications for health care professionals, working with individuals living with chronic pain, are discussed.

There is a curious and paradoxic phenomenon, reliably demonstrated in animal models, that consists of an increased sensitivity to pain that is apparently induced by the very opioid drugs used to ameliorate the pain. This phenomenon is termed "opioid-induced hyperalgesia." Whether opioid-induced hyperalgesia occurs in humans, and, if so, to what extent and consequence, is far less established. This is a critical question for attempting to treat pain. ⋯ It would be to decrease, rather than increase, the dose of opioid. We review the evidence, particularly the clinical evidence, about opioid-induced hyperalgesia and the postulated mechanisms. We conclude that given the clinical ramifications, opioid-induced hyperalgesia is one of the most understudied important aspects of opioid research.
