Costs of compensated work loss for low back pain have risen dramatically. Current healthcare management of this condition may contribute to this trend. Researchers are currently investigating the degree to which healthcare practitioners' attitudes and beliefs may influence their patient management. Measures used to assess healthcare practitioners' attitudes and beliefs have often been adapted from patient tools. The degree to which they have been assessed for use with different populations varies. ⋯ Statistical methods used suggest that the measure demonstrates good reliability with a GP population. The influence of training on attitudes and beliefs of GPs is discussed.

To investigate the changes in surface and intramuscular electromyographic (EMG) activity at latent trigger points (TrPs) in the extensor carpi radialis brevis muscle after injection of either glutamate or isotonic saline into latent TrPs in the infraspinatus muscle. ⋯ Our results show that an increased nociceptive activity at latent TrPs in the infraspinatus muscle may increase motor activity and sensitivity of a TrP in distant muscles at a same segmental level.

Sickle cell disease-related pain is difficult to treat adequately. Pain secondary to vasoocclusive episodes (VOE) may be unresponsive to high-dose intravenous opiates. Alternative treatment options for VOE are needed. We sought to review our experience with low-dose ketamine for children hospitalized with VOE. ⋯ Further research into ketamine for vasoocclusive pain is warranted.

To examine characteristics of sleep and sleep complaints in older persons with chronic pain, as compared to older persons with neither sleep complaints nor chronic pain, on the basis of objective and subjective sleep assessment. ⋯ Sleep complaints such as disruptive sleep and problems initiating and maintaining sleep, and impairment in daytime functioning, are prevalent in older adults with chronic pain. Sleep and sleep complaints should be addressed to a much greater extent in this patient group.

Pain is identified as the third largest health problem in the world, impacting sleep, physical functioning, and psychologic functioning. Pain has been viewed as a multidimensional experience influenced by biology, psychology, cultural conditioning, expectancies, and social contingencies. The aims of this study were to examine the psychometric properties and the differential item functioning (DIF) of the short-form McGill Pain Questionnaire (SF-MPQ) to test the cultural differences in verbally based pain expression. ⋯ Test bias was relatively small (0.74) given the entire scale of the SF-MPQ (0 to 45), indicating that this measure seems to be used equivalently across these 2 groups. This study shows 1 method in evaluating the cross-cultural validity of pain assessment instruments, and contributes to the understanding of cross-cultural variability in item reporting on the SF-MPQ.
