Despite increasing interest in the attentional biases of pain patients towards pain-related stimuli, there have been no investigations of whether the main caregivers of chronic pain patients also selectively attend to pain-related information. We compared the attentional biases to painful or happy faces of 120 chronic pain patients, 118 caregivers, and 50 controls. Analyses found that both patients and caregivers demonstrated biases towards painful faces that were not observed in control participants or to happy faces. ⋯ These results add to the growing weight of evidence suggesting that biases towards pain-related stimuli are observed in chronic pain patients, but that the nature of the stimuli is important. In addition, the results suggest that caregivers, particularly those who either under- or overestimate the level of pain that the patient reports, also demonstrate similar biases. Future research should investigate the links between caregivers' biases and the way in which caregivers respond to pain.

Comparative StudyReliability and group differences in quantitative cervicothoracic measures among individuals with and without chronic neck pain.
Clinicians frequently rely on subjective categorization of impairments in mobility, strength, and endurance for clinical decision-making; however, these assessments are often unreliable and lack sensitivity to change. The objective of this study was to determine the inter-rater reliability, minimum detectable change (MDC), and group differences in quantitative cervicothoracic measures for individuals with and without chronic neck pain (NP). ⋯ Results demonstrate the feasibility of obtaining objective cervicothoracic impairment measures with acceptable inter-rater agreement across time. The clinical utility of these measures is supported by evidence of impaired mobility, strength, and endurance among patients with NP, with corresponding MDC values that can help establish benchmarks for clinically significant change.

SUMMARY ⋯ Pregabalin 300 mg/day as an add-on to transdermal buprenorphine 35 µg/h led to significant pain reduction and a significant reduction of interference with sleep quality in patients with chronic low back pain.

Effectiveness and safety of tapentadol prolonged release with tapentadol immediate release on-demand for the management of severe, chronic osteoarthritis-related knee pain: results of an open-label, phase 3b study.
This open-label, phase 3b study (ClinicalTrials.gov Identifier: NCT00983073) evaluated the effectiveness, and tolerability of tapentadol for severe, chronic osteoarthritis knee pain that was inadequately managed with World Health Organization (WHO) Step I or II analgesics or co-analgesics, or that was not treated with regular analgesics. Prior to starting study treatment, patients discontinued any WHO Step II analgesics, while Step I analgesics and/or co-analgesics were continued at the same dose. Patients received tapentadol prolonged release (50-250 mg bid) during a 5-week titration period and a 7-week maintenance period. ⋯ Corresponding significant improvements from baseline to Weeks 6 and 12 were observed in the Western Ontario and McMaster Universities osteoarthritis index, the EuroQol-5 Dimension health status questionnaire, the Short Form-36 health survey, and the Hospital Anxiety and Depression Scale (all P ≤ 0.0103). Treatment-emergent adverse events were in line with those observed in previous studies of tapentadol prolonged release. Overall, the results of this study indicate that tapentadol treatment results in significant improvements in pain intensity, health-related quality of life, and function in patients with inadequately managed, severe, chronic osteoarthritis knee pain.

Surgical injury can frequently lead to chronic pain. Despite the obvious importance of this problem, the first publications on chronic pain after surgery as a general topic appeared only a decade ago. This study tests the hypothesis that chronic postsurgical pain was, and still is, represented insufficiently. ⋯ Chronic postsurgical pain is still a neglected topic, except for pain after herniorrhaphy. The change in the attitude toward chronic postsurgical pain is the important first step in the approach to this problem.
