Chronic pain syndromes are associated with alterations in sleep continuity and sleep architecture. One perspective of this relationship, which has not received much attention to date, is that disturbances of sleep affect pain. To fathom this direction of cause, experimental human and animal studies on the effects of sleep deprivation on pain processing were reviewed. ⋯ Furthermore, sleep deprivation can counteract analgesic effects of pharmacological treatments involving opioidergic and serotoninergic mechanisms of action. The heterogeneity of the human data and the exclusive interest in rapid eye movement sleep deprivation in animals so far do not allow us to draw firm conclusions as to whether the hyperalgesic effects are due to the deprivation of specific sleep stages or whether they result from a generalized disruption of sleep continuity. The significance of opioidergic and serotoninergic processes as mediating mechanisms of the hyperalgesic changes produced by sleep deprivation are discussed.

There are many potential barriers to adequate cancer pain management, including lack of physician education and prescription monitoring programs. The authors surveyed physicians about their specific knowledge of pain management and the effects of the regulation of opioids on their prescribing practices. ⋯ The details of opioid prescribing are crucial areas to target education for cancer pain management. The surveyed physicians accepted the need for regulation of opioid prescribing with very few being fearful of scrutiny from the College of Physicians and Surgeons of British Columbia. However, the inconvenience of the triplicate prescription pad was more of a barrier to prescribing, it being of concern to 20% of respondents, particularly surgeons and medical specialists.

To explore the attitudes of family physicians (FPs) toward the use of opioids in the management of chronic noncancer pain (CNCP) in the Calgary Health Region (CHR), Calgary, Alberta. ⋯ FPs in the CHR need to increase their comfort level toward opioids in general to adequately manage CNCP. Their lack of comfort may reflect a lack of education or fear of regulatory scrutiny.

To report on a long term experience in treating patients with chronic noncancer pain (CNCP). ⋯ This is a large sample of CNCP patients, most taking opioids over a long period of time. CNCP can be treated by opioids safely and with a modest effect, with improvement in functioning in some patients who are refractory to other measures. If care is taken, opioids may even be used effectively for patients with a history of chemical dependency.

Comparative Study
Parental judgements of infant pain: importance of perceived cognitive abilities, behavioural cues and contextual cues.
Despite blatant indications, such as behavioural and contextual cues, infant pain is often undermanaged by adult caretakers. The belief that infants are limited in their abilities to comprehend the meaning of an experience or recall that experience has been used to minimize or deny the need for intervention in this vulnerable population. ⋯ Parents judged that infants undergoing a routine immunization were experiencing clinically significant levels of pain. However, despite generally acknowledging a developing trajectory for memory and understanding across the five age groups, parents did not indicate that a child's ability to remember and understand pain were essential features of their pain judgements. The results indicated that memory and understanding did not influence parental judgements of infant pain demonstrating the validity of the parents' self-assessments.
