Fibromyalgia, also known as fibrositis and muscle rheumatism, is a common, noninflammatory, painful musculoskeletal disorder. It is common between the ages of 30 and 60 years and has a female to male ratio of 5 to 1. Essential symptoms of fibrositis are pain, fatigue, disturbed sleep, morning stiffness and local tenderness. Subjective swelling, paresthesia and numbness sometimes occur. Multiple host and environmental factors seem to contribute to the onset and course of fibromyalgia. Modest improvement follows treatment by antidepressive agents, physical measures and reduction in stress. In this study 60 patients with fibromyalgia were investigated and the clinical characteristics of these patients are described and compared with those in other studies.

Fibromylagia is a painful musculoskeletal disorder composed of core features that are always present (wide-spread pain and tenderness), characteristic features that are present more than 75 per cent of the time (fatigue, nonrefreshed sleep, and morning stiffness), and common features that are present more than 25 per cent of the time (for example, paresthesia, irritable bowel syndrome, functional disability). The syndrome is common, occurring in 2.1 per cent of family practice clinic patients, 5 per cent of general medical patients, and 10 to 20 per cent of rheumatic disease clinic patients. Evolving diagnostic criteria permit identification of patients for clinical and research purposes.

In ergonomic epidemiology exposure to local loads as well as cardiovascular load may contribute to general and local fatigue and musculoskeletal disease. Self-reported exposure is often the only feasible method in large population studies. The aim of this study was to evaluate retrospectively self-reported physical activity and perceived exertion as estimates of cardiovascular load during occupational work. The study population consisted of 39 men, representing 25 different occupations, and 58 women, representing 28 occupations. Ratings of physical exertion (RPE scale) and physical activity (Edholm scale transferred to multiples of the basal metabolic rate, METs) at the end of a work shift were correlated with the average heart rate during the same work shift. In the male population, both RPE ratings and METs correlated significantly (P < .01) with the average heart rate. No such correlation was observed in the female population.

Fibromyalgia is a musculoskeletal disorder characterized by generalized myalgias, arthralgias widespread tender points in discreet areas on examination. It is frequently accompanied by fatigue, stiffness, and a nonrestorative sleep pattern. These patients generally have a normal blood count and chemistry profile. There is a subset of people with fibromyalgia (FM) who test positive for the antinuclear antibody (ANA) and have constitutional symptoms that resemble those of patients with early lupus. We studied the immunologic profile of patients with FM who are ANA-positive (+). A retrospective review of patient records in a university-based rheumatology practice was conducted. In a group of 66 FM patients, 30% (20) were ANA+, with a 75% preponderance of the speckled pattern and 20% diffuse pattern. The remaining 5% were equally split between diffuse-speckled and speckled-nucleolar patterns. All had negative staining for extractable nuclear antibodies. The Smart Index (SI), a ratio of the sedimentation rate to one-half the patient's age, was developed to characterize each patient's inflammatory response. The FM patients who were ANA negative (-) had a mean SI of 0.55, whereas the FM patient's who were ANA+ had a SI of 1.07. These ANA+ patients represent a subgroup of patients who have FM with an inflammatory response profile larger than that of the ANA-patients.

Personnel who work with laboratory animals incur potential occupational health risks that can lead to the development of musculoskeletal disorders. Demanding manual tasks may also result in increased errors, worker fatigue, poor human performance, and decreased productivity. Studies have shown that a comprehensive ergonomics program that utilizes a systematic risk management approach can reduce the likelihood of exposure to musculoskeletal disorder risk factors and remove barriers to human performance. Research has characterized the risk factors of musculoskeletal disorder exposure in terms of force, frequency, posture, and muscle exertion. Ergonomic risk factors for typical animal handling tasks and work areas are identified, and a method is suggested for prioritizing interventions using interrelated data indicators. An initial review of potential control measures is offered to improve the health, safety, and effectiveness of people involved in the care and use of research animals.

A 36-yr-old woman began to suffer from headache, anorexia and general fatigue at 35 weeks' gestation. About 2 or 3 months after the delivery, fever, tachycardia and generalized musculoskeletal disorder appeared. Thereafter, they worsened rapidly, accompanied by a disturbance of consciousness and hypercalcemia. Thyrotoxicosis, due to a post-partum thyroiditis, and glucocorticoid deficiency, due to a pituitary failure, probably associated with lymphocytic hypophysitis, were also observed. All the symptoms and hypercalcemia disappeared after the glucocorticoid replacement therapy and the normalization of thyroid hormone levels. Serum and urinary bone resorption markers, such as urine pyridinoline (U-Pyr), urine deoxypyridinoline (U-DPD), urine amino-terminal telopeptide of type I collagen (U-NTx) and serum carboxy-terminal telopeptide of type I collagen (ICTP), were extremely high at the hypercalcemic state. In this case, they were 10 to 20 times higher than the normal upper limits, and then markedly decreased in a normocalcemic state, thereby showing an extreme acceleration of bone resorption in a state of both thyrotoxicosis and glucocorticoid deficiency.

Fibromyalgia (FM) is a syndrome characterized by chronic widespread pain, stiffness, nonrestorative sleep, fatigue, and comorbid conditions. Fibromyalgia has undergone a major paradigm shift in recent years. It is no longer considered a musculoskeletal disorder per se; rather, it represents one end of a spectrum of disorders characterized by chronic widespread pain. Hence, oral health care providers may be the first to recognize signs and symptoms of this complex disorder and are often consulted to participate in the management of FM patients. This medical management update will review the epidemiology, classification, etiology and pathophysiology, clinical presentation, and therapeutic advances in FM. This review will also highlight issues that are important to the oral health care provider, including orofacial manifestations and dental considerations for patients with FM.

We performed this study to examine the prevalence and correlates of fatigue and depression, and their relevance to health-related quality of life in disease-free breast cancer survivors. A total of 1,933 breast cancer survivors recruited from five large hospitals in Korea completed a mailed survey, which included the Brief Fatigue Inventory, Beck Depression Inventory, European Organization for Research and Treatment of Cancer QLQ-C30, and QLQ-BR23. With a framework that included sociodemographic, clinical, and symptom characteristics, multivariate logistic regression models were used to identify factors associated with fatigue and depression. Among breast cancer survivors, 66.1% reported moderate to severe fatigue and 24.9% reported moderate to severe depression. Risk factors common to both fatigue and depression were lower income, dyspnea, insomnia, appetite loss, constipation, and arm symptoms. Risk factors for fatigue only included younger age, employment, presence of gastrointestinal disease, and pain. Having a musculoskeletal disease was identified as a risk factor for depression only. Both fatigue and depression were influenced by sociodemographic factors, comorbidity and symptom characteristics rather than cancer or treatment-related factors. Both fatigue and depression were negatively associated with survivors' health-related quality of life. However, the patterns of differences in health-related quality of life according to severity of fatigue or depression were similar. This concurrent examination of risk factors for fatigue and depression may be helpful in the development of clinical management strategies in disease-free breast cancer survivors.

Muscle fatigue is commonly associated with the musculoskeletal disorder problem. Previously, various techniques were proposed to index the muscle fatigue from electromyography signal. However, quantitative measurement is still difficult to achieve. This study aimed at proposing a method to estimate the degree of muscle fatigue quantitatively. A fatigue model was first constructed using handgrip dynamometer by conducting a series of static contraction tasks. Then the degree muscle fatigue can be estimated from electromyography signal with reasonable accuracy. The error of the estimated muscle fatigue was less than 10% MVC and no significant difference was found between the estimated value and the one measured using force sensor. Although the results were promising, there were still some limitations that need to be overcome in future study.

Repetitive Strain Injuries (RSIs)/Work-Related Musculoskeletal Disorders (WMSDs) are a major issue in Brazilian public health. The way such sickness is produced, its multidetermined origin and the troubled care provided to sufferers point to the very contradictions of the capitalist production system. This work aims at understanding the macrosocial processes surfaced in the workers' search for cure of RSIs/WMSDs, paying close attention to the negotiation and (re-)signification processes present in those trajectories. By drawing on 'explanatory models' and the concept of 'therapeutic itinerary', 'thematic analysis' of in-depth interviews with Brazilian workers receiving Social Security compensation was used to approach the socioeconomic and political realms. Culpability and excess were reported in connection with etiology whereas pain, tiredness and stress were shown to be related to symptom initiation. Legal medical assessment, rehabilitation programs and prognosis were all along (re-) signified by the interviewees in an attempt to create an 'ideal type' of productive worker despite the injury. It is then urged that public health policies responsive to the wider organization and processes of power and class related to the care of RSIs/WMSDs are devised.
