Case Reports
Postoperative respiratory depression with pregabalin: a case series and a preoperative decision algorithm.
Pregabalin is gaining popularity in the perioperative period for its usefulness in treating neuropathic pain and its apparent opioid- sparing effect. The present report describes the perioperative course of three patients who received pregabalin and experienced significant respiratory depression in the postoperative period. All three patients consented to the report and publication of the present case series. ⋯ Based on the authors' experience and the available evidence, they believe that pregabalin may be useful in the management of acute pain in carefully selected patients undergoing certain surgeries. A clinical algorithm has been developed to guide the perioperative use of pregabalin. This algorithm may be helpful in increasing the safety of perioperative pregabalin use.

The present study examined the relationship between couple concordance of catastrophizing and adverse pain outcomes. Possible mechanisms underlying the relationship between couple concordance of catastrophizing and pain outcomes were also explored. Fifty-eight couples were recruited for the study. ⋯ These findings suggest that high catastrophizing chronic pain patients may need to increase the 'volume' of pain communication to compensate for low catastrophizing spouses' tendency to underestimate the severity of their pain experience. Patients' perceived solicitousness and punitive response from the spouse could not explain the group differences in pain behaviour. Theoretical and clinical implications of the findings are discussed.

One of the most commonly neglected findings in the human pain literature is the observation of sex differences in the mechanisms that support the phenotypic expression of pain. The present commentary describes an assessment of the prevalence of observed sex differences in various pain processes, and of how expert pain researchers interpret the epidemiology and, hence, the proximate and ultimate causes of such differences. ⋯ Investigator responses indicated that sex differences are pervasive across various areas of pain research, that sex differences are particularly pronounced in the area of situational influences on pain behaviors, and that contemporary pain researchers largely disagree on the epidemiology of, and hence, proximate and ultimate causes of the differences. The relevance of social situational factors on sex differences in pain behaviours is discussed in the context of evolutionary, developmental, social psychology and pain sensory systems that may function, in part, for regulating interpersonal intimacy.
