Randomized Controlled Trial Comparative Study
A Comparison of the Sensitivity of Brush Allodynia and Semmes-Weinstein Monofilament Testing in the Detection of Allodynia Within Regions of Secondary Hyperalgesia in Humans.
Two of the most common Quantitative Sensory Techniques (QST) employed to detect allodynia include mechanical brush allodynia and Semmes-Weinstein monofilaments. However, their relative sensitivity at detecting allodynia is poorly understood. The purpose of this study was to compare the sensitivity of brush allodynia against Semmes-Weinstein monofilament technique for detecting allodynia within regions of secondary hyperalgesia in humans. ⋯ Brush allodynia is more sensitive than Semmes-Weinstein monofilaments for detecting mechanical allodynia in regions of secondary hyperalgesia. Brush allodynia may be preferred over Semmes-Weinstein monofilaments for clinical applications requiring reliable detection of allodynia.

Clinical Trial
Prediction of Acute Postoperative Pain Following Breast Cancer Surgery Using the Pain Sensitivity Questionnaire: A Cohort Study.
Previous studies have indicated that preoperative pain sensitivity correlates with postoperative pain intensity, and thus may be used to predict severe postoperative pain. Self-rating of pain sensitivity using the "Pain Sensitivity Questionnaire (PSQ)" may be an adjunct to these measures. ⋯ Results need to be validated in a larger cohort and for other types of surgery, but use of the simple PSQ may help to identify patients at risk of intense acute postoperative pain.

Acute postoperative pain delays recovery and increases morbidity and mortality. Traditional administration of postoperative analgesics by nurses is often inefficient. The present study evaluated the safety, efficacy, and usability of a novel, patient-controlled analgesic dispenser, the PCoA Acute. ⋯ The study confirmed that PCoA Acute is safe and effective. It is well accepted by patients and medical staff. Its use can optimize pain medication administration.

Under-assessment and inadequate treatment of pain is a common problem for older adults, particularly those with dementia. This may be in part attributed to knowledge deficits and negative attitudes among healthcare staff and informal caregivers towards pain, its assessment and its management in dementia. Knowledge and attitudes have a significant predictive relationship with behavior, potentially impacting pain assessment and management practices. ⋯ Understanding and positive attitudes were demonstrated in some areas, such as non-narcotic pain medications and identifying behavioral pain indicators. Of the 4 scales identified, positive results were found for internal consistency and content validity, however further refinement and testing is necessary. It was concluded attitudinal and knowledge barriers exist which should be addressed given their influence over practice behavior, however, there is a willingness and knowledge base from which progress can build.

The "Douleur Neuropathique 4 (DN4) questionnaire" was developed for screening neuropathic pain. The purpose of this work was to validate the DN4 questionnaire in the standard Arabic language. First, the questionnaire was translated and semantically adapted to Arabic according to the international guidelines for cross-cultural adaptation. ⋯ The sensitivity and specificity of the 7-item DN4 and 10-item DN4 were not influenced by either pain severity or educational level. In conclusion, this new Arabic version DN4 questionnaire is a simple, reliable, and valid tool for discriminating between neuropathic and non-neuropathic pain. It represents a useful tool in clinical setting and population-based studies.
