The Transition of Acute Postoperative Pain to Chronic Pain: An Integrative Overview of Research on Mechanisms.
Chapman CR and Vierck CJ. J Pain 2017 - Review. PMID 27908839
The nature of the transition from acute to chronic pain still eludes explanation, but chronic pain resulting from surgery provides a natural experiment that invites clinical epidemiological investigation and basic scientific inquiry into the mechanisms of this transition. ...PERSPECTIVE: The development of chronic pain after surgery is a major clinical problem that provides an opportunity to study the transition from acute to chronic pain at epidemiologic and basic science levels. ...

Chronic musculoskeletal pain and its impact on older people.
Blyth FM and Noguchi N. Best Pract Res Clin Rheumatol 2017 - Review. PMID 29224694
Clustering of musculoskeletal pain with other pain conditions is also common, and the number of pain sites is an important prognostic factor. While musculoskeletal pain is usually nociceptive in origin, older people with musculoskeletal conditions may also experience neuropathic pain and central pain syndromes. ...

Assessment of Patient-Reported Outcome Instruments to Assess Chronic Low Back Pain.
Ramasamy A, et al. Pain Med 2017 - Review. PMID 28340111
OBJECTIVE: To identify patient-reported outcome (PRO) instruments that assess chronic low back pain (cLBP) symptoms (specifically pain qualities) and/or impacts for potential use in cLBP clinical trials to demonstrate treatment benefit and support labeling claims. ...RESULTS: Thirteen instruments were selected and reviewed: Low Back Pain Bothersomeness Scale, Neuropathic Pain Symptom Inventory, PainDETECT, Pain Quality Assessment Scale Revised, Revised Short Form McGill Pain Questionnaire, Low Back Pain Impact Questionnaire, Oswestry Disability Index, Pain Disability Index, Roland-Morris Disability Questionnaire, Brief Pain Inventory and Brief Pain Inventory Short Form, Musculoskeletal Outcomes Data Evaluation and Management System Spine Module, Orebro Musculoskeletal Pain Questionnaire, and the West Haven-Yale Multidimensional Pain Inventory Interference Scale. ...

Predictors of persistent pain after breast cancer surgery: a systematic review and meta-analysis of observational studies.
Wang L, et al. CMAJ 2016 - Review. PMID 27402075 Free PMC article.
Moderate-quality evidence suggested an association with the presence of preoperative pain (OR 1.29, 95% CI 1.01-1.64). Given the 30% risk of pain in the absence of risk factors, the absolute risk increase corresponding to these ORs ranged from 3% (acute postoperative pain) to 21% (axillary lymph node dissection). ...INTERPRETATION: Development of persistent pain after breast cancer surgery was associated with younger age, radiotherapy, axillary lymph node dissection, greater acute postoperative pain and preoperative pain. ...

Defining chronic pain in epidemiological studies: a systematic review and meta-analysis.
Steingrímsdóttir ÓA, et al. Pain 2017 - Review. PMID 28767506
The objective was to document the operational definitions applied in epidemiological studies of chronic pain and to examine whether pain definitions and other methodological factors are systematically related to prevalence estimates. ...Meta-analyses and meta-regressions were applied with random effects models; covariates were geography, sampling year, survey method, sampling frame, participation rate, percentage women of all participants, pain duration, and pain location. ...

The Global Spine Care Initiative: a summary of the global burden of low back and neck pain studies.
Hurwitz EL, et al. Eur Spine J 2018. PMID 29480409
In 2015, over half a billion people worldwide had low back pain and more than a third of a billion had neck pain of more than 3 months duration. Low back and neck pain are the leading causes of years lived with disability in most countries and age groups. CONCLUSION: Low back and neck pain prevalence and disability have increased markedly over the past 25 years and will likely increase further with population aging. ...

Chronic Pain in the Elderly: The Case for New Therapeutic Strategies.
Paladini A, et al. Pain Physician 2015 - Review. PMID 26431140 Free article.
In general, pain threshold increases with age while the threshold of pain tolerance remains unchanged or decreases. Additionally, other important modifications of the pain perception system in this age group consist in a clear reduction in the descending inhibitory capacity with an associated increase in central sensitization. ...Since these cells are the primary interlocutors for pain neurons, their alterations lead to changes that promote persistent neuroinflammation, thereby impacting pain neuronal cell functionality. ...

Prevalence and Predictors of Chronic Postsurgical Pain in Children: A Systematic Review and Meta-Analysis.
Rabbitts JA, et al. J Pain 2017 - Review. PMID 28363861 Free PMC article.
Presurgical pain intensity, child anxiety, child pain coping efficacy, and parental pain catastrophizing were the only presurgical factors identified as predictive of CPSP. ...Presurgical pain intensity, and child and parent psychosocial factors predicted CPSP. Additional resources and interventions are needed for youth who report persistent pain after surgery....
