Characteristics of Chronic Pain Patients Who Take Opioids and Persistently Report High Pain Intensity.
CONCLUSIONS: Our findings suggest that patients with persistently high pain scores despite opioid therapy are more likely than those with lower levels of pain to present with characteristics associated with having centralized pain. This study cannot determine whether these characteristics were present before (fibromyalgia-like patient) or after the initiation of opioids (opioid-induced hyperalgesia). Regardless, patients with a centralized pain phenotype are thought to be less responsive to opioids and may merit alternative approaches. PMID: 24310048 [PubMed - as supplied by publisher]

Comparisons of patient and physician assessment of pain-related domains in cancer pain classification: results from a large international multicenter study.
Abstract UNLABELLED: The aim of the present study is to compare physician clinical assessment with patient-rated evaluations in the classification of cancer pain patients into groups with different pain levels, according to the presence of incident/breakthrough pain, neuropathic pain, and psychological distress. Average pain in the previous 24 hours was used as the dependent variable in multivariate linear regression models, and incident/breakthrough pain, neuropathic pain, and psychological distress were tested as regressors; in the assessment of regressors, physicians used the Edmonton Classification System for...

Experimental jaw muscle pain increases pain scores and jaw movement variability in higher pain catastrophizers.
CONCLUSION: The increased reported pain intensity, pain areas, and pain rating indices are consistent with enhanced central sensitization processes in high-catastrophizing individuals. The slower velocity and greater variability of repetitive jaw movements in higher pain catastrophizing individuals in acute experimental pain may reflect changes in motor coordination as an example of avoidance behavior for the jaw motor system.

Can Experimentally Evoked Pain in the Jaw Muscles or Temporomandibular Joint Affect Anterior Bite Force in Humans?
Conclusion: Experimental pain from either masseter muscle or TMJ did not affect the MVBF, in accordance with the subject-based reports. Jaw muscle activity, except for EMG activity of the anterior temporalis and anterior digastric muscles during TMJ pain, also remained unaffected by pain. The findings suggest that it is not pain in itself but rather how pain is perceived that may lead to adaptation of motor function, supporting an integrated pain adaptation model.

Percutaneous and Endoscopic Adhesiolysis in Managing Low Back and Lower Extremity Pain: A Systematic Review and Meta-analysis.
CONCLUSION: The evidence is Level I or strong that percutaneous adhesiolysis is efficacious in the treatment of chronic refractory low back and lower extremity pain. Percutaneous adhesiolysis may be considered as a first-line treatment for chronic refractory low back and lower extremity pain. The evidence is Level II to III that spinal endoscopy is effective in the treatment of chronic refractory low back and lower extremity pain. Key words: Spinal pain, chronic low back pain, post lumbar surgery syndrome, epidural scarring, adhesiolysis, endoscopy, radicular pain. PMID: 26815254 [PubMed - as supplied by publisher]

Widespread Pressure Pain Hyperalgesia in Chronic Nonspecific Neck Pain with Neuropathic Features: A Descriptive Cross-Sectional Study.
CONCLUSIONS: Widespread pressure pain hyperalgesia was detected in patients with CNSNP with NF, but not in patients with CNSNP with No-NF. Patients with CNSNP presented bilateral pressure pain hyperalgesia over the cervical region and a decreased cervical ROM compared to healthy controls. However, no differences were found between the 2 CNSNP groups. These findings suggest differences in the mechanism of pain processing between patients with CNSNP with NF and No-NF.

Pain assessment in context: a state of the science review of the McGill pain questionnaire 40 years on
Abstract: The McGill pain questionnaire (MPQ) and its later derivative the short form-MPQ have been used widely both in experimental and clinical pain studies. They have been of considerable importance in stimulating research into the perception of pain and now, with the publication of its latest variant, the short form-MPQ-2, it is appropriate to appraise their utility in the light of subsequent research into the nature of pain and the purpose of pain assessment. Following a description of the content and development of the questionnaires, issues of validity, reliability, and utility are addressed, not only in terms of th...

Finding Ways to Lift Barriers to Care for Chronic Pain Patients: Outcomes of Using Internet-Based Self-Management Activities to Reduce Pain and Improve Quality of Life.
Conclusion. Self-management support interventions, such as Internet-based educational tools, can be considered to help patients manage their chronic pain, depression, and anxiety and may be helpful to improve the treatment outcome in patients who could not otherwise afford noninsured services.

Temporomandibular Disorder Pain and Related Factors in an Adult Population: A Cross-Sectional Study in Southern Sweden.
CONCLUSION: The prevalence of TMD pain in the adult population in southern Sweden was 11%. Factors related to TMD pain were female gender, age < 50 years, headaches, self-reported poor general health, high scores on the OHIP-14, and tooth wear. Age was the only factor that showed a significant difference between genders for TMD pain. PMID: 28118419 [PubMed - in process]

Ischemic Ulcer Pain Is Both Nociceptive and Neuropathic Pain Based on a Discriminant Function Analysis Using the McGill Pain Questionnaire.
Authors: Kogure T, Sumitani M, Abe H, Hozumi J, Inoue R, Mietani K, Kawahara K, Yamada Y Abstract The McGill Pain Questionnaire (MPQ) is composed of 78 words reflecting the mechanisms underlying chronic pain conditions. Ischemic ulcer pain is generally regarded as a nociceptive and inflammatory pain condition. However, it is sometimes refractory to nonsteroidal anti-inflammatory drug (NSAID) and opioid treatment. We categorized ischemic pain into nociceptive/inflammatory pain (NocP) or neuropathic pain (NeP), on the basis of patients' descriptions of their pain using the MPQ. We investigated pain characteristics of...

A New Equation for Predicting Evolution of Oral Pain in Orthodontic Treatment: A Longitudinal, Prospective Cohort Study.
CONCLUSION: The equation reproduced the data registered and can be applied to studies of pain derived from archwires, and this methodology could be used for other external agents fitted in the mouth. Patients receiving dental treatment involving external agents can be made aware of the pain they can expect to experience. This will enable them to distinguish expected pain from other pain, which will help them identify other pathologies requiring medical attention and to approach treatment with better motivation since the pattern of pain evolution is known in advance.

Cross-Cultural Validation of the Brazilian Portuguese Version of the Pain Vigilance and Awareness Questionnaire.
CONCLUSION: The Brazilian Portuguese version of the PVAQ was found to be adequate and reliable when applied to the sample. The methodologic considerations presented could improve research on pain vigilance and help clinicians assess PVAQ factors among patients. PMID: 29145523 [PubMed - as supplied by publisher]

Relationship Between Psychosocial Factors and Pain in the Jaw and Neck Regions Shortly After Whiplash Trauma.
CONCLUSION: Shortly after a whiplash trauma, pain in the jaw and neck regions is associated with the severity of psychosocial factors. Thus, psychosocial factors may play a role in the development of pain in the jaw region after whiplash trauma. PMID: 30371684 [PubMed - as supplied by publisher]

Epidemiology of physician-diagnosed neuropathic pain in Brazil.
Conclusion: Evaluation of chronic pain patients in Brazil yielded a 14.5% probable NeP prevalence. NSAIDs and opioids were commonly used, and there was a high incidence of NeP-related symptoms with varying levels of dysfunction across subtypes. PMID: 30662280 [PubMed]
