Introduction Stings from the lionfish (Pterois volitans) constitute one of the most painful wounds in the ocean. This species has invaded the Atlantic coast of the United States, Gulf of Mexico, Caribbean, and Mediterranean Sea. In addition to its ecological impact on local fish populations, stings from the lionfish pose a medical problem because o...

The National Institutes of Health (NIH) minimum dataset for chronic low back pain (CLBP) was developed in response to the challenge of standardizing measurements across studies. Although reference values are critical in research on CLBP to identify individuals and communities at risk of poor outcomes such as disability, no reference values have bee...

Objective: Knee osteoarthritis (OA) is a disease of multiple phenotypes of which a chronic pain phenotype (PP) is known. Previous PP studies have focused on one domain of pain and included heterogenous variables. We sought to identify multidimensional PPs using the IMMPACT recommendations and their relationship to clinical outcomes. Methods: Par...

Background Chronic low back pain (CLBP) is a major cause of disability globally. Stratified care has been proposed as a means to improve prognosis and treatment, but is generally based on limited aspects of pain, including biopsychosocial drivers. Aims Following IMMPACT recommendations, the present study explored pain phenotypes with a sample of w...

Introduction The presence of multiple coexisting chronic pain (CP) conditions (eg, low-back pain and migraines) within patients has received little attention in literature. The goals of this observational longitudinal study were to determine the prevalence of coexisting CP conditions, identify the most frequent ones and patterns of coexistence, inv...

Background: Many chronic pain (CP) awareness and educational initiatives have been achieved but it is time to take stock of where we are today. Aims: To describe and identify determinants of knowledge, beliefs and attitudes of different subgroups of the Quebec population regarding CP, and especially towards people suffering from this condition. Met...

Background: Though multidisciplinary pain treatment (MPT) is considered the gold standard for managing chronic pain, it is unclear which patients benefit most from this high-cost treatment approach. Aims: The goals were to identify subgroups of patients sharing similar pain severity trajectories over time and predictors of MPT responsiveness. Metho...

Objective: The objective of this study was to identify biopsychosocial factors predicting primary care chronic non-cancer pain (CNCP) patients’ risk of being heavy health care users. Methods: Patients reporting moderate to severe CNCP for at least 6 months with an active analgesic prescription from a primary care physician were recruited in communi...

Accumulating evidence suggests an association between patient pretreatment expectations and numerous health outcomes. However, it remains unclear if and how expectations relate to outcomes following treatments in multidisciplinary pain programs. The present study aims at investigating the predictive association between expectations and clinical out...

Pregabalin is frequently prescribed for chronic non-cancer pain. No previous study has examined its off-label use. Our primary aim was to assess the proportion of patients taking pregabalin for conditions approved by Health Canada ("on-label") and compare their perspectives on its use to those who use pregabalin for other conditions ("off-label")....

Primary care providers’ knowledge, attitudes and beliefs (KAB) regarding chronic noncancer pain (CNCP) are a barrier to optimal management. OBJECTIVES: To evaluate and identify the determinants of the KAB of primary care physicians and pharmacists, and to document clinician preferences regarding the content and format of a continuing education prog...

As the two principal research investigators, we are pleased that our large, long-term, multicentre study on persistent postcardiac surgery pain was published in CMAJ.1 However, we strongly take issue with the Editor’s comment in the April 15 print synopsis version regarding the data in the full-text article. We point out the editor’s misunderstandi...

Background / Purpose: Health interventions based on patient empowerment have been shown to improve chronic pain self-management and have a positive impact on quality of life. A new structured interdisciplinary group intervention aimed at patient empowerment, known as PASSAGE Program, was found to be effective regarding patient global impression o...

Background / Purpose: A large clinical database named the Quebec Pain Registry (QPR) was put in place in the province of Quebec in 2008. This clinical, administrative, and research infrastructure includes all new patients who are seen and followed within three of the four Pain Centers of Expertise of the Quebec University Health Networks. In orde...

Background / Purpose: In primary care, the extent to which non-cancer chronic pain (NCCP) patients seek treatment from complementary medicines and self-management techniques is not well documented. The aim of the study was to document the prevalence of use of these approaches in NCCP patients followed by a family physician.In a cross-sectional su...

This is the protocol for a review and there is no abstract. The objectives are as follows: To assess the effectiveness of interventions to manage pain related to simple fractures in children in an ED. To identify the most effective interventions, if any, for reducing patient discomfort due to simple fractures.

Study objectives: We assess pain and pain-related functional interference in patients discharged from the emergency department (ED). Methods: After written informed consent, patients underwent structured interviews conducted by research assistants at ED discharge and were contacted as early as 3 days after discharge for telephone interviews. Medica...

Through the introduction of the gate control theory and various subsequent works, Ronald Melzack has inspired many investigators worldwide to realize two important facts about pain. First, incoming pain messages are subject to both negative and positive modulation, which significantly affect its perception. Second, the progression of knowledge abou...
