Clinical Trial
Short- and long-term outcomes of children with complex regional pain syndrome type I treated with exercise therapy.
To report the initial and long-term outcome after an intensive exercise therapy program for childhood complex regional pain syndrome, type I (CRPS). ⋯ Intense exercise therapy is effective in initially treating childhood CRPS and is associated with low rate of long-term symptoms or dysfunction.

Comparative Study
Signs and symptoms in complex regional pain syndrome type I/reflex sympathetic dystrophy: judgment of the physician versus objective measurement.
To assess the relation between the subjectively assessed and objectively measured diagnostic signs and symptoms in complex regional pain syndrome type I (CRPS I) and to quantify their severity. ⋯ Bedside evaluation of CRPS I with Veldman's criteria was in good accord with psychometric or laboratory testing of these criteria.

Previous researchers have reported that in psychiatric populations many patients provide incorrect self-report information on current drug use. Therefore, the purposes of the present study were to determine the percentage of chronic pain patients (CPPs) using illicit drugs (cannabis, cocaine), to determine the percentage of CPPs who provide incorrect self-report drug use information in the psychiatric examination, and to identify some variables that could help in identifying the CPP likely to provide an incorrect drug use history using drug urine toxicologies. DESIGN/SETTING/PARTICIPANTS/OUTCOME MEASURES: Two hundred seventy-four CPP consecutive admissions to a pain facility were psychiatrically examined according to criteria in the Diagnostic and statistical manual of mental disorders (3rd ed., rev; DSM-III-R), with special emphasis on all current drug use. Immediately after the psychiatric examination, all CPPs were asked to consent to urine toxicology. Urine was tested for benzodiazepines, opioids, tricyclics, propoxyphene, cannabinoids, barbiturates, amphetamines, methadone, methaqualone, phencyclidine, alcohol, and cocaine. CPPs were then segregated into three groups: negative toxicology, positive toxicology but concordant with self-report of current drug use, and positive toxicology discordant with self-report of current drug use. These groups were statistically compared with each other with regard to age, gender, race, workers' compensation status, and prevalence of individual DSM-III-R psychoactive substance use disorders. Sensitivities were also calculated for two conditions: accuracy of toxicology and accuracy of self-report. ⋯ A significant percentage of CPPs appears to provide incorrect information on current illicit drug use. Urine toxicology studies may have a place in the identification of drugs for which incorrect information may be provided by CPPs. There are many possible reasons, such as assay error, that could lead to apparent misinformation. In the clinical setting, these possibilities should be considered if urine toxicology results appear to be incongruent with psychiatric examination drug use self-report.

The purposes of the study were threefold: (a) to determine whether a measurement system based on facial expression would be useful in the assessment of post-operative pain in young children; (b) to examine construct validity in terms of structure, consistency, and dynamics of the facial display; and (c) to evaluate concurrent validity in terms of associations with global judgments of the children's pain. ⋯ The present study demonstrated that the CFCS serves as a valid measurement tool for persistent pain in children.

Considerable research suggests that females exhibit greater sensitivity to laboratory pain procedures than do males; however, whether the presence of acute clinical pain influences this sex difference in pain sensitivity has not been investigated. The present experiment investigated the effects of sex and acute dental pain on laboratory pain responses. ⋯ These data suggest that the sex difference in thermal pain sensitivity frequently reported in pain-free subjects appears to be absent in patients presenting with acute dental pain. However, this effect cannot be explained solely based on the presence of clinical pain because the effect on pain threshold and tolerance persisted into session 2, when pulpitis patients were pain free. Potential explanations for these results are discussed.
