Obstructive sleep apnea, central sleep apnea, sleep related hypoventilation, Biot's or ataxic breathing, and cluster breathing are some of the commonly described sleep disorders in patients who are on long-term opioids. Continuous positive airway pressure that is commonly used to treat obstructive sleep apnea may not be effective in treating sleep-disordered breathing in long-term opioid users, and an adaptive servoventilator (ASV) may be needed. ⋯ In this case, ASV, though effective, was not tolerable due to chronic facial pain, and successful withdrawal of methadone at our pain rehabilitation center resolved the sleep-disordered breathing and improved daytime sleepiness. This is to our knowledge the first case report of resolution of sleep-disordered breathing and improvement in daytime sleepiness after withdrawal of long-term opioid use.

The Danish Barriers Questionnaire-II: preliminary validation in cancer pain patients.
The objective of this study was to examine the psychometric properties of the Danish version of the Barriers Questionnaire-II (DBQ-II). ⋯ The DBQ-II seems to be a reliable and valid measure of the barriers to pain management among Danish cancer patients.
