Hyperreactive Brain Network May Be Cause of Chronic Pain in Fibromyalgia, Study Suggests

Fibromyalgia is one of the overlapping pain conditions with TMD. This article appeared in Fibromyalgia News Today on January 15, 2018. A new study suggests a hyperreactive brain network may be the underlying cause of chronic pain in fibromyalgia.

Dry Eye Linked to Chronic Overlapping Pain in Veteran Population

There may be a correlation between dry eye and chronic pain in the US military veteran population as is evident by a recent study. Ocular pain was most strongly associated with headaches, tension headaches, migraines, temporomandibular joint disorders, pelvic pain, central pain syndrome, and fibromyalgia in the veteran patient population.

Patients in Los Angeles or New York City Needed for Clinical Study - Comparative Study of Women Considering or Currently Receiving Botox© Injections for TMJ Pain

Are you a woman with "TMJ" pain in facial muscles, who has either: a. recently had Botox© injections for your pain or b. not had Botox© for your pain but has thought about such treatment? If either is true for you, you may qualify for an observational research study centrally administered by the NYU College of Dentistry. It is funded by the National Institutes of Health (NIH). The purpose of this study is to understand potential health risks that may be caused by treating "TMJ pain" with Botox© injections.

Why Head and Face Pain Cause More Suffering

Hate headaches? The distress you feel is not all in your -- well, head. People consistently rate pain of the head, face, eyeballs, ears and teeth as more disruptive, and more emotionally draining, than pain elsewhere in the body.

Migraine and Coronary Artery Disease: A Genetic Connection

There has long been as association between migraine headaches and vascular (blood vessel) dysfunction of some kind, underscored by epidemiological studies and other research. New evidence for a genetic connection now comes from the analysis of several large data sets of each condition based on Genome Wide Association Studies (GWAS).

From Functional Pains to Central Sensitivity Syndromes

  • Dec 17, 2016

The following article in Medscape refers to TMD and some of its overlapping pain conditions as functional pains and proposes to change that description. Medscape is the leading online resource for physicians and healthcare professionals worldwide, offering the latest medical news and expert perspectives; essential point-of-care drug and disease information; and relevant professional education and CME.

When a patient presents with pain of no obvious organic origin, they are often labelled as having 'functional' pain. The exact diagnosis is derived from the organ system displaying the predominant symptoms e.g. musculoskeletal pain in fibromyalgia (FM) or visceral pain in irritable bowel syndrome (IBS).

The worldwide prevalence of all functional pain syndromes (FPS) is 15-20%. World Health Organization (WHO) surveys reveal that ~10% of primary care patients develop a chronic pain condition within 12 months of initial registration. Of these, at least 50% continue to have symptoms beyond 1 yr. FPS cause enormous economic burden on society with concurrent ramifications for the individual's family in particular and society in general. FM alone has been estimated to cost around £4000 per patient per year.

There has been a paradigm shift in the understanding of FPS. The old model of multiple discrete chronic pain conditions is being replaced by a more overarching, although no less complex, state of central sensitivity syndrome (CSS). Evidence is being accrued that FPS represent the phenotypic output of a complex interplay between genetic susceptibility, gene-environment interactions, and environmental triggers.

Four common FPS will be reviewed in this article: FM, IBS, temporomandibular dysfunction (TMD), and chronic cardiac chest pain (CCCP). The pathophysiology and management of each will be examined and the case presented for a shared underlying mechanism called CSS. Once this new mechanism is adopted more widely, it will allow for future novel management options to be developed in a coherent and systematic manner.  Click here to read full article: http://www.medscape.com/viewarticle/870947_1
