Comparative StudyEthnic Differences Identified by Pain Sensitivity Questionnaire Correlate With Clinical Pain Responses.
The Pain Sensitivity Questionnaire, English version (PSQ-E), is predictive of pain-related responses to experimental stimuli. Ethnic differences have been noted in experimental measures of pain sensation using quantitative sensory testing. The present study sought to determine if the PSQ-E also identified similar ethnic differences. ⋯ The study demonstrated significantly elevated pain sensitivity in AA compared with NHW patients as measured by the PSQ-E and experimental and clinical pain intensity scores. This shows that the PSQ reflects the known elevation of pain sensitivity in AA subjects and suggests that it may be useful in assessing pain treatment disparities by identifying and standardizing differences in pain sensitivity.

Observational StudySensory Assessment and Regression Rate of Bilateral Oblique Subcostal Transversus Abdominis Plane Block in Volunteers.
The analgesic effect and duration of a transversus abdominis plane (TAP) block remain controversial. Transversus abdominis plane blocks are effective for somatic/incisional pain but do not provide analgesia for visceral pain from intra-abdominal procedures. The purpose of this study was to assess the area and extent of cutaneous sensory blockade and the regression of dermatomal anesthesia after bilateral oblique subcostal TAP block. ⋯ Bilateral oblique subcostal TAP block produces a widespread cutaneous sensory blockade with a consistent dermatomal distribution in the midabdomen for a considerable effective duration.

Local Application of Ultrasound Attenuates Neuropathic Allodynia and Proinflammatory Cytokines in Rats After Thoracotomy.
We aimed to investigate the effect of therapeutic ultrasound (TU) on pain sensitivity and the concentration inflammatory cytokines in a thoracotomy rat model. ⋯ Mechanical allodynia was partially resolved with TU. Tissue temperature increased with ultrasound, while TU restricted the up-regulation of interleukin 1β and TNF-α around the injured intercostal nerve.
