Chronic Pain Disability in the Workplace

Chronic pain disorders have been associated with increasing disability expenditures in Western industrialized countries. The reason for this increase is unknown. Many chronic pain disorders have been characterized by a lack of readily demonstrable pathology, resistance to treatment and associated psychosocial difficulties. The difficulties inherent in the diagnosis and treatment...

Can We Distinguish between Inflammatory and Neuropathic Pain?

Inflammatory and neuropathic pain were once considered to be distinct entities. However, research over the past decade or so has brought to light many shared mechanisms, and the distinction between the two is no longer clear. Consideration of mechanisms, symptoms and the effects of analgesic drugs does not reveal any definitive or universally applicable differentiating factors...

Catastrophizers with Chronic Pain Display more Pain Behaviour when in a Relationship with a Low Catastrophizing Spouse

The present study examined the relationship between couple concordance of catastrophizing and adverse pain outcomes. Possible mechanisms underlying the relationship between couple concordance of catastrophizing and pain outcomes were also explored. Fifty-eight couples were recruited for the study. The chronic pain patients were filmed while lifting a series of weighted canisters...

Chronic pain negatively affects various aspects of daily life, such as by decreasing the motivation to work and reward sensitivity, which may lead to difficulties in daily life or even unemployment. Human and animal studies have shown that chronic pain damages...

The Mediating Effect of Central Sensitization on the Relation between Pain Intensity and Psychological Factors: A Cross-Sectional Study with Mediation Analysis

Background. Central sensitization (CS) and psychological factors are associated with pain intensity; however, the mediating role of CS on the relation between psychological factors and pain intensity remains unclear. Objectives. We performed mediation analysis to investigate how CS mediates relation between psychological factors and pain intensity. Methods. Twenty patients with...

Risk Factors Associated with Upper Extremity Musculoskeletal Disorders among Barbers in Gondar Town, Northwest Ethiopia, 2018: A Cross-Sectional Study

Background. Work-related upper extremity musculoskeletal disorders (WUEDs) often present remarkable health and economic burdens on society. Occupational barbers are usually neglected both in research and policy actions, mainly in developing countries, and hence are likely subjected to the conditions. So far, information about factors that influence WUEDs among barbers in Ethiopia...

Comparison of Nonimage- and Fluoroscopy-Guided Interlaminar Epidural Block: A Matched Paired Analysis in the Same Individuals

Background. Although fluoroscopic guidance is recommended highly for more accurate lumbar interlaminar epidural steroid injection (L-ESI), many physicians still use a nonimage-guided approach for L-ESIs. However, because of its associated risk of radiation and increased medical expense, the cost-effectiveness and safety of fluoroscopy-guided ESI have been called into question...

Living with Chronic Pain: A Qualitative Study of the Daily Life of Older People with Chronic Pain in Chile

One of the main causes of chronic pain in older people is spine deformity, an abnormal curvature of the spine. The purpose of this study is to improve understanding of the experience of chronic pain produced by spinal deformity in older people and understand how cultural factors may affect this experience. A qualitative study was performed with 10 older people. Participants were...

The Quebec Task Force on Whiplash-Associated Disorders and the British Columbia Whiplash Initiative: A Study of Insurance Industry Initiatives

Two studies on whiplash-associated disorders that were generated by insurance companies were reviewed. The Quebec Task Force (QTF) report was comprised of a cohort study, a best evidence synthesis and consensus recommendations. The British Columbia Whiplash Initiative (BCWI) propagated the QTF recommendations.

OBJECTIVE: To assess the prevalence, treatment and impact of chronic pain in Canada.

Treating Stress-Related Pain with the Flotation Restricted Environmental Stimulation Technique: Are There Differences between Women and Men?

The aim of the present study was to explore, for the first time, sex differences among patients diagnosed with stress-related pain before and after flotation restricted environmental stimulation technique (REST) treatment, delivered 12 times during seven weeks. The present study included 88 patients (69 women, 19 men) from three different studies (post hoc analysis). They had...

Posterior Interscalene Block: An Ultrasound-Guided Case Series and Overview Of History, Anatomy and Techniques

BACKGROUND: The posterior interscalene block has been described as an alternative to the lateral interscalene block. However, this technique has not gained popularity because of the close proximity of the approach to vascular and central neural structures.

Exploring the Lived Experience of Adults using Prescription Opioids to Manage Chronic Noncancer Pain

BACKGROUND: Chronic noncancer pain (CNCP) and prescription opioid use is a highly complex and growing health care issue in Canada. Many quantitative research studies have investigated the effectiveness of opioids for chronic pain; however, gaps remain in the literature regarding the personal experience of using opioids and their impact on those experiencing CNCP.

Comparison of Different Histone Deacetylase Inhibitors in Attenuating Inflammatory Pain in Rats

Histone deacetylase inhibitors (HDACIs), which interfere with the epigenetic process of histone acetylation, have shown analgesic effects in animal models of persistent pain. The HDAC family comprises 18 genes; however, the different effects of distinct classes of HDACIs on pain relief remain unclear. The aim of this study was to determine the efficacy of these HDACIs on...

Xm2 Scores for Estimating Total Exposure to Multimodal Strategies Identified by Pharmacists for Managing Pain: Validity Testing and Clinical Relevance

Objective. To assess the validity of an exposure score obtained from the Xm2 tool for all pharmacological and nonpharmacological strategies used by individuals to manage chronic pain. Methods. Using data from individuals with chronic pain, eXposure multimodal (Xm2) scores were calculated by assigning one point for every 100 mg of morphine equivalent used (opioid medications); 25...

Investigation of the Correlation between Postherpetic Itch and Neuropathic Pain over Time

Postherpetic itch (PHI), or herpes zoster itch, is an intractable and poorly understood disease. We targeted 94 herpes zoster patients to investigate their pain and itch intensities at three separate stages of the condition (acute, subacute, and chronic). We used painDETECT questionnaire (PDQ) scores to investigate the correlation between PHI and neuropathic pain. Seventy-six...
