The authors reviewed the available pediatric pain literature and selected those studies that reported quantitative information on the reliability and validity of, and the optimal cutoff points for, the visual analog scale (VAS) when used as an observational pediatric pain tool. ⋯ Further psychometric testing needs to be conducted on intraobserver reliability, responsiveness, and optimal cutoff points. Future research may guide the choice between VAS (obs) and the numerous behavioral pain instruments.

Chronic pain is prevalent in many Western countries. Its prevalence in a non-Caucasian population is not known. The authors performed this study to measure the prevalence of chronic pain in the Hong Kong Chinese adult population, as well as the pattern of pain and the demographic characteristics, the impact on social and work function, and the help-seeking behavior of those with pain. ⋯ The study showed that the prevalence of chronic pain in Hong Kong adults was approximately 10.8%. Work and daily life are significantly affected and there is considerable demand on the health care system. Despite the ethnic difference, the prevalence, pattern, and demographic characteristics of chronic pain in Hong Kong are very similar to those seen in Western countries.

Comparative Study Clinical Trial
Contribution of individual spa therapies in the treatment of chronic pain.
The aim of the present study was to evaluate the contribution of individual spa therapies administered during a period of 3 weeks on measures of well being and pain in a sample of patients with chronic back pain. ⋯ The results indicate that, in addition to the individual therapies, other factors relating to spa therapy as a whole must contribute to overall treatment outcome. In addition, the results support the efficacy of exercise therapy for chronic back pain.

Randomized Controlled Trial Comparative Study Clinical Trial
The treatment of fear of movement/(re)injury in chronic low back pain: further evidence on the effectiveness of exposure in vivo.
Several cognitive-behavioral factors contribute to the persistence of pain disability in patients with chronic back pain. Fear-avoidance beliefs and fear of movement/(re)injury in particular have been shown to be strong predictors of physical performance and pain disability. Patients reporting substantial pain-related fear might benefit from exposure in vivo to a set of individually tailored, fear-eliciting, and hierarchically ordered physical movements rather than more general graded activity. ⋯ Time series analysis of the daily measures showed that improvements in pain-related fear and pain catastrophizing occurred only during the exposure in vivo and not during the graded activity, irrespective of the treatment order. Analysis of the pretreatment to post-treatment differences also revealed that decreases in pain-related fear also concurred with decreases in pain disability and pain vigilance and an increase in physical activity levels. All improvements remained at the 1-year follow-up.

Recognition is growing that self-report of drug use, prescribed or otherwise, among patients with chronic pain treated with opioids is often unreliable. This fact is well known to the addiction management community. Patients may inaccurately report use of prescribed medications, fail to report use of nonprescribed medications or medications prescribed by other physicians, or fail to report use of illicit drugs. ⋯ The authors review the use of urine toxicology testing in monitoring patients with chronic pain, including laboratory aspects. They also present evidence from recent studies that suggests that monitoring the behavior alone of patients on chronic opioid treatment will fail to detect potential problems revealed by urine toxicology testing. The authors conclude that, although further research is urgently needed, at this time it is appropriate to conduct routine urine toxicology testing in patients with chronic pain treated with opioids.
