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.

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.

Intravenous regional sympathetic block is a valued component of the pain clinician's armamentarium for the management of the complex regional pain syndrome type 1. Treatment of this multifaceted condition is multimodal, and despite a lack of convincing supporting evidence from clinical trials, the author makes the case for retaining the technique while recommending both appropriate guidance and further study.

Chronic neuropathic pain (CNP) in spinal cord injury (SCI) is recognized as severely compromising, in both adjustment after injury and quality of life. Studies indicate that chronic pain in SCI is associated with great emotional distress over and above that of the injury itself. Currently, little is known about the SCI patient's perception of the impact of living with chronic neuropathic pain. ⋯ Medication failure was identified as a common outcome, while strategies including use of warm water, swimming, increased activity and distraction provided temporary pain relief. Learning to live with the pain appeared to be related to acceptance of pain, which in turn seemed to facilitate adjustment. Further research is warranted to determine the process by which SCI patients learn to live with CNP and coping strategies that facilitate adjustment to CNP in SCI patients.

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.
