Self-report is the "gold standard" for pain assessment, however, observational pain scales, such as Doloplus-2 must be used for patients who cannot communicate. In this follow-up study, we report the psychometric properties of the observational Doloplus-2 scale using the visual analog scale (VAS) pain score as a gold standard and evaluate its performance. ⋯ The observational Doloplus-2 scale correlates moderately with self-assessment pain score and has adequate internal consistency. Our data also suggest that Doloplus-2 could be substantially shortened as the brief version performed similarly to the complete Doloplus-2.

Clinical Trial
Unipedicular vertebroplasty for osteoporotic compression fracture using an individualized needle insertion angle.
In the classic transpedicular vertebroplasty, second needle placement is routinely required at the same level. However, each patient requires a different needle insertion angle (NIA) at each site. Therefore, precise NIA is required for each fractured vertebral body. In this study, we performed a unipedicular approach through an individualized NIA that had been evaluated with axial magnetic resonance imaging before vertebroplasty. ⋯ Unipedicular PVP can be performed safely, provided the operator has a thorough knowledge of the bony landmarks and the anatomy of the pedicle. A unipedicular approach could be considered first using individualized NIA at each vertebral level.

It is claimed that transcutaneous electrical nerve stimulation (TENS) operates via a segmental mechanism by reducing ongoing transmission and sensitization of nociceptive dorsal horn neurons. Hence, TENS electrodes are usually placed at the site of pain. ⋯ Taken at face value, the findings suggest that TENS effects were nonspecific and that electrode location does not affect outcome. However, this study should be seen as a call for further research rather than a definitive conclusion.

To evaluate interrater reliability using 5 newly trained observers in the assessment of pressure pain threshold (PPT) using a fixed-angle algometer. ⋯ This study provides new evidence that trained observers can apply an algometer at a consistent rate and provide highly reliable measures of PPT in healthy humans, when PPT is calculated as the mean of 3 trials.

Physicians frequently express dissatisfaction about caring for patients with chronic pain and frequently report that inadequate training and concern about addiction are impediments to prescribing opioids. Elderly patients with chronic pain may be at increased risk of experiencing uncontrolled pain and this patient population is increasingly being cared for by geriatricians rather than internists. We sought to determine if there is a differential impact on internists and geriatricians of the factors that adversely affect attitudes toward opioid prescribing. ⋯ Factors shown to have an adverse affect on opioid prescribing disproportionately impact on the attitudes of internists compared with geriatricians. Further research is needed to determine if there is also a differential impact on how internists care for their elderly patients with chronic pain.
