Abstract
Fibromyalgia syndrome (FMS) is a clinical disorder predominant in females with unknown etiology and medically unexplained symptoms (MUS), similar to other afflictions, including irritable bowel syndrome (IBS), chronic fatigue syndrome (CFS), post-traumatic stress disorder (PTSD), Gulf War illness (GFI), and others. External environmental stimuli drive behavior and impact physiologic homeostasis (internal environment) via autonomic functioning. These environments directly impact the individual affective state (mind), which feeds back to regulate physiology (body). FMS has emerged as a complex disorder with pathologies identified among neurotransmitter and enzyme levels, immune/cytokine functionality, cortical volumes, cutaneous innervation, as well as an increased frequency among people with a history of traumatic and/or emotionally negative events, and specific personality trait profiles. Yet, quantitative physical evidence of pathology or disease etiology among FMS has been limited (as with other afflictions with MUS). Previously, our group published findings of increased peptidergic sensory innervation associated with the arterio-venous shunts (AVS) in the glabrous hand skin of FMS patients, which provides a plausible mechanism for the wide-spread FMS symptomology. This review focuses on FMS as a model affliction with MUS to discuss the implications of the recently discovered peripheral innervation alterations, explore the role of peripheral innervation to central sensitization syndromes (CSS), and examine possible estrogen-related mechanisms through which external and internal environmental factors may contribute to FMS etiology and possibly other afflictions with MUS.

Abstract
Fibromyalgia syndrome after comprehensive treatment of breast cancer is rare and seldom reported. Here we present a case of a 50-year-old female patient,who was admitted to the hospital because of generalized fibromyalgia for 3 months and brain metastasis after the right breast carcinoma surgery for 1 month, and the clinical diagnosis was brain metastasis from breast carcinoma combined with fibromyalgia syndrome. The fibromyalgia were relieved with proper symptomatic treatment but the patient eventually died of tumor progression.

Abstract
OBJECTIVES The objective of this study is to determine the prevalence of fibromyalgia (FM) in systemic lupus erythematosus (SLE) patients and to study its relationship to depression and other SLE-related factors. METHODS A cross-sectional data analysis from the RELESSER-Transversal Spanish Registry, which includes SLE patients in a national multicentre retrospective charts review, was performed. INCLUSION CRITERIA patients who fulfilled ≥4 ACR 1997 SLE criteria. Main variables were disease duration, depression, sociodemographics, comorbidities, SLE activity symptoms, serological findings, therapies and different disease status indices. Statistical analyses included a descriptive, associative and logistic regression analyses. A literature review was performed. RESULTS 3,591 SLE patients were included, 90.1% women, 34.6 years of age at diagnosis (SD 14.6 years) and 93.1% Caucasians. FM prevalence was 6.2%. SLE patients with disease duration >5 years showed more FM than those with duration <5 years: 6.9% vs. 4.0%, respectively (p<0.05). SLE-FM patients showed higher prevalence of depression compared to non-FM-SLE patients: 53.1% vs. 14.6%, respectively (p<0.001). After adjusting by risk factors, the OR (CI) of suffering depression in FM-SLE patients was 6.779 (4.770-9.636), p<0.001. The OR of having secondary Sjögren's 2.447 (1.662-3.604), p<0.001, photosensitivity 2.184 (1.431-3.334), p<0.001, and oral ulcers 1.436 (1.005-2.051), p=0.047. CONCLUSIONS Prevalence of FM in Caucasian SLE patients was high compared to the general population, and was significantly higher in those in later stages of disease. SLE patients with depression showed a strong risk of developing FM. Photosensitivity, oral ulcers and secondary Sjögren's were the only SLE-related factors associated with FM.

Abstract
OBJECTIVES To evaluate the impact of concomitant fibromyalgia on the rating of pain, fatigue, and dysfunction, in patients with various rheumatic disorders. METHODS A cross-sectional study was carried out in a hospital-based rheumatology unit. Standard clinical and laboratory data were obtained and all patients completed questionnaires on pain, fatigue, and daily function. The rate of concomitant fibromyalgia was estimated using the 1990 American College of Rheumatology (ACR) classification criteria for fibromyalgia and the analysis concentrated on visual analogue scales (VAS). RESULTS Six hundred and eighteen visits of 383 patients with inflammatory as well as non-inflammatory rheumatic disorders were analyzed. Concomitant fibromyalgia was noted in 74 patients (23% of the cohort). Patients with rheumatic diseases and concomitant fibromyalgia had significantly higher mean VAS scores for pain, fatigue, and function (79±17, 81±18, 80±18, respectively) as compared to patients who had no features of fibromyalgia (47±28, 50±29, 44±30 respectively; all p values <0.001). The scores reported by patients with rheumatic diseases and concomitant fibromyalgia were similar to the scores obtained from patients with primary FM. CONCLUSIONS Concomitant FM is common both among patients with inflammatory and patients with non inflammatory rheumatic disorders. Concomitant FM has a remarkable impact on the severity of symptoms and, moreover, patients with concomitant FM exhibit extreme and significantly distinct levels of pain and fatigue which is as severe as that reported by patients with primary FM. It seems that fibromyalgic features dominate and become the main cause of morbidity in rheumatological patients with concomitant FM.

Abstract
Physical, mental and social well-being are important outcomes in patients with chronic rheumatic diseases, including systemic lupus erythematosus (SLE). The MOS SF-36 and the WHO QoL Bref are appropriate for assessing quality of life (QoL) in patients with SLE. The QoL of patients with SLE is impaired compared with that of controls. Fibromyalgia adversely affects the QoL of SLE patients. Women with SLE had significantly lower scores on subscales of the sense of coherence (SoC) compared with matched controls. This reduced SoC in SLE women represents impaired adaptive coping and is independently associated with reduced QoL in women with SLE. Depression and anxiety are common among SLE patients, and the frequency is similar to that in patients with rheumatoid arthritis. A reciprocal longitudinal relationship between depression and illness intrusiveness was found in patients with SLE. Disease activity and damage are not associated with depression. The subjective experience, not the illness per se, causes depression.

Abstract
Sleep disturbances, affective disorders, pain and fatigue are often present in individuals affected by fibromyalgia (FM). The pathophysiology of FM is not yet well understood and, to date, no treatment has been proven to be fully effective in alleviating all symptoms. Adopting a transdiagnostic perspective could thus be useful for clinicians: treatment would target a transdiagnostic process across a range of disturbances, not just a single disorder. The aim of this review is to revise the available literature about the potential role of sleep disturbances as a transdiagnostic process in FM symptomatology and mood or anxiety disorders comorbidity. We are proposing a model under which sleep disturbances can play a central role. Because conditions of sleep loss are related to the activation of the stress system, including the activation of the inflammation system, we propose this mechanism as a key one: it can be shared by mental, sleep disturbances and pain in FM and it may explain, in part, the high levels of comorbidity between them. In this frame-work sleep disturbances may play a key role and be the target of therapeutic strategies across FM symptomatology and mental disorders.

Abstract
OBJECTIVES Clinical features of primary Sjögren's syndrome (pSS) overlap with those of fibromyalgia (FM). This cross-sectional study was conducted to investigate the prevalence of FM in pSS patients and to compare the clinical features of pSS patients with FM to those without FM. METHODS One hundred pSS patients were consecutively assessed to identify the presence of FM according to the American College of Rheumatology (ACR) 2010 criteria. Clinical and laboratory data were collected from all patients. Additional assessments included EULAR Sjögren's Syndrome Patient Reported Index (ESSPRI) and EULAR Sjögren's Syndrome Disease Activity Index (ESSDAI). The severity of depression was measured by Hamilton depression rating scale 17-items (HAM-D scale). RESULTS The prevalence of FM was 31.0% (31/100) in pSS. Widespread pain index and symptom severity scale were significantly correlated with ESSPRI (r=0.6542 and r=0.7173, both p<0.0001) and HAM-D scale (r=0.6734 and r=0.6471, both p<0.0001) in pSS. In multivariate analysis, ESSPRI and HAM-D scale were independently associated with increase of tender point count and symptom severity scale. ESSPRI was significantly higher in pSS patients with FM compared to those without FM (p<0.0001). The prevalence of FM in pSS patients with moderate-to-severe depression was significantly higher than those with mild depression or without depression (odds ratio= 10.62, p=0.0009). Serum 25-hydroxy vitamin D3 levels in pSS patients with FM were significantly (p=0.0072) decreased compared to those without FM. CONCLUSIONS Our study showed that FM was prevalent in pSS. FM was associated with higher ESSPRI and more severe depression.

Abstract
OBJECTIVES Fibromyalgia and chronic pain have previously associated with HIV infection for over two decades. We aimed to evaluate the prevalence of FMS symptoms in an ethnically heterogeneous population of HIV-infected individuals in southern Israel, applying the proposed new diagnostic criteria for diagnosis of fibromyalgia symdrome (FMS). METHODS 156 HIV-positive patients followed at the AIDS clinic of the Soroka University Medical Center (SUMC) who gave written informed consent were recruited in the trial. FMS was diagnosed based on the widespread pain index (WPI) and the Symptom Severity Score (SSS) comprising the modified 2011 diagnostic criteria for FMS. CD4 levels ad viral load were obtained. RESULTS One hundred and thirty-nine patients (89.1%) were receiving HAART (Highly Active Antiretroviral Therapy). A total of 22 patients (14.1%) were found to fulfill current criteria for diagnosis of FMS. FMS-criteria positive individuals were slightly younger than criteria-negative individuals (40.3±9.2 vs. 42.6±11.9, p=0.39), but this difference did not reach statistical significance. There was no significant difference between the groups regarding gender, family status, religion, occupation or education. No correlation was found between CD4 and viral load levels and symptoms of FMS. CONCLUSIONS Despite the dramatic improvement in management of HIV, FMS symptoms remain highly prevalent among these patients and are not directly correlated with indices of active disease. FMS is an important clinical issue to address among patients suffering from HIV infection.

Abstract
Fibromyalgia is the currently preferred term for widespread musculoskeletal pain, typically accompanied by other symptoms such as fatigue, memory problems, and sleep and mood disturbances, for which no alternative cause can be identified. Earlier there was some doubt about whether there was an "organic basis" for these related conditions, but today there is irrefutable evidence from brain imaging and other techniques that this condition has strong biological underpinnings, even though psychological, social, and behavioral factors clearly play prominent roles in some patients. The pathophysiological hallmark is a sensitized or hyperactive central nervous system that leads to an increased volume control or gain on pain and sensory processing. This condition can occur in isolation, but more often it co-occurs with other conditions now being shown to have a similar underlying pathophysiology (eg, irritable bowel syndrome, interstitial cystitis, and tension headache) or as a comorbidity in individuals with diseases characterized by ongoing peripheral damage or inflammation (eg, autoimmune disorders and osteoarthritis). In the latter instance, the term centralized pain connotes the fact that in addition to the pain that might be caused by peripheral factors, there is superimposed pain augmentation occurring in the central nervous system. It is important to recognize this phenomenon (regardless of what term is used to describe it) because individuals with centralized pain do not respond nearly as well to treatments that work well for peripheral pain (surgery and opioids) and preferentially respond to centrally acting analgesics and nonpharmacological therapies.

Abstract
The etiopathogenesis of the algo-dysfunctional syndromes, which include chronic fatigue syndrome, fibromyalgia and irritable bowel syndrome, is still debated, but it is widely accepted that it is best described by a multifactorial model that include genes, environmental factors such as external infections, inflammation, dietary habits, impaired endogenous cortisol production, the aberrant activation of some areas of the central nervous system, and small peripheral nervous fibre damage. This complexity suggests that they should be managed by means of a multidisciplinary approach involving the use of both pharmacological and non-pharmacological treatments. The aim of this review is to discuss the most recent scientific acquisitions concerning these syndromes and their treatment.

Abstract
BACKGROUND The multiple symptoms of chronic fatigue syndrome (CFS) and fibromyalgia resemble those described in patients suffering from autoimmune/inflammatory syndrome induced by adjuvants (ASIA). It has been suggested that chronic metal-induced inflammation might play a role both in CFS and fibromyalgia as well as in ASIA. Humans are exposed to metals mainly through the release of metal ions from corroding dental restorations and orthopedic implants, food, vaccines and jewelry. Metals readily bind to sulphur and other groups in the mitochondria, enzymes and cell proteins. Metal-bound proteins are recognized by the immune system of susceptible subjects and might trigger an abnormal immune response, including allergy and autoimmunity. OBJECTIVES To study three subjects with CFS and two with fibromyalgia, all of whom suspected metal exposure as a trigger for their ill health. METHODS We measured delayed-type hypersensitivity to metals (metal allergy) using a validated lymphocyte transformation test, LTT-MELISA. All patients except one were sensitized to metals present in their dental restorations. The remaining patient reacted to metals in his skull implant. The removal of sensitizing metals resulted in long-term health improvement. Nine healthy controls matched for gender and age showed only marginal reactivity to the metals tested. CONCLUSIONS Patients with CFS and fibromyalgia are frequently sensitized to metals found in the environment or used in dentistry and surgery. This allergy to metals might initiate or aggravate non-specific symptoms in metal-sensitized patients.

Abstract
BACKGROUND Chronic fatigue syndrome (CFS) and fibromyalgia (FM) are both highly prevalent conditions associated with extreme disability and with the development of co-morbid psychiatric disorders, such as depression and anxiety. Childhood stressors have been shown to induce persistent changes in the function of biological systems potentially relevant to the pathogenesis of both CFS and FM, such as the inflammatory system and the hypothalamic-pituitary-adrenal (HPA) axis. In this review, we examined whether multiple forms of childhood stressors are contributing factors to the development of these disorders, and of the associated psychiatric symptoms. METHOD Using PubMed, we identified 31 papers relevant to this narrative review. We included cohort studies and case-control studies, without any exclusion in terms of age and gender. No study characteristics or publication date restrictions were imposed. RESULTS Most studies across the literature consistently show that there is a strong association between experiences of childhood stressors and the presence of CFS and FM, with rates of CFS/FM being two- to three-fold higher in exposed than in unexposed subjects. We also found evidence for an increased risk for the development of additional symptoms, such as depression, anxiety and pain, in individuals with CFS and FM with a previous history of childhood stressors, compared with individuals with CFS/FM and no such history. CONCLUSIONS Our review confirms that exposure to childhood stressors is associated with the subsequent development of fatigue syndromes such as CFS and FM, and related symptoms. Further studies are needed to identify the mechanisms underlying these associations.

Abstract
This study sought to determine the prevalence of fibromyalgia syndrome and to identify whether fibromyalgia was associated with various clinical symptoms and laboratory parameters in hemodialysis patients. One hundred and forty-eight hemodialysis patients were examined for fibromyalgia symptoms according to the American College of Rheumatology criteria. Demographic characteristics, as well as causes of kidney failure, dialysis duration, and symptoms related to fibromyalgia were investigated. Of 148 patients, 18 (12.2%) were diagnosed with fibromyalgia. Patients with fibromyalgia had significantly poorer sleeping satisfaction than the control group (P = .02).The Beck Depression Inventory score was higher in 77.8% of the fibromyalgia patients than that in the control group (P = .006), but there was no significant difference in the anxiety score between the two groups (P = .86).In conclusion, there was a higher prevalence of fibromyalgia in hemodialysis patients than previously reported. Sleep disturbances and depression levels correlated with fibromyalgia.

Abstract
The purpose of this review is to examine the evidence for a relationship between mercury (Hg) exposure from dental amalgams and certain idiopathic chronic illnesses--chronic fatigue syndrome (CFS), fibromyalgia (FM), depression, anxiety, and suicide. Dental amalgam is a commonly used dental restorative material that contains approximately 50% elemental mercury (Hg0) by weight and releases Hg0 vapor. Studies have shown that chronic Hg exposure from various sources including dental amalgams is associated with numerous health complaints, including fatigue, anxiety, and depression--and these are among the main symptoms that are associated with CFS and FM. In addition, several studies have shown that the removal of amalgams is associated with improvement in these symptoms. Although the issue of amalgam safety is still under debate, the preponderance of evidence suggests that Hg exposure from dental amalgams may cause or contribute to many chronic conditions. Thus, consideration of Hg toxicity may be central to the effective clinical investigation of many chronic illnesses, particularly those involving fatigue and depression.

Abstract
OBJECTIVES Ethan B. Russo's paper of December 1, 2003 explored the concept of a clinical endocannabinoid deficiency (CECD) underlying the pathophysiology of migraine, fibromyalgia, irritable bowel syndrome and other functional conditions alleviated by clinical cannabis. METHODS Available literature was reviewed, including searches via the National Library of medicine database and other sources. RESULTS A review of the literature indicates that significant progress has been made since Dr. Ethan B. Russo's landmark paper, just ten years ago (February 2, 2004). Investigation at that time suggested that cannabinoids can block spinal, peripheral and gastrointestional mechanisms that promote pain in headache, fibromyalgia, irritable bowel syndrome and muscle spasm. CONCLUSION Subsequent research has confirmed that underlying endocannabinoid deficiencies indeed play a role in migraine, fibromyalgia, irritable bowel syndrome and a growing list of other medical conditions. Clinical experience is bearing this out. Further research and especially, clinical trials will further demonstrate the usefulness of medical cannabis. As legal barriers fall and scientific bias fades this will become more apparent.

Abstract
Fibromyalgia syndrome (FMS) is characterised by diffuse muscle pain, poor sleep and unrelenting fatigue. Individuals with FMS may also experience headaches, anxiety, depression, poor memory, numbness and tingling in the extremities, cold hands and feet, irritable bowel syndrome and lowered immune function. FMS is a common chronic pain syndrome of unknown etiology and limited treatment options. Previous studies have reported oxidative stress in FMS patients, but the results were inconsistent. Oxidative stress and nitric oxide is involved in FMS pathophysiology, however, it is still not clear whether oxidative stress abnormalities are the cause of FMS. There are several studies indicating oxidative stress in patients with FMS. Oxidant (Malondialdehyde) and antioxidant (Superoxide dismutase) balances were found to be changed in FMS patients. Furthermore, increased free radical levels may be responsible for the development of FMS and free radical-mediated oxidative stress including inflammatory cytokines may also play important roles in its pathogenesis. Moreover, oxidative stress is supposed to be increased in patients with FMS which is related to the severity of FMS symptoms. Therefore, it is important to understand whether the oxidative stress parameters are involved in FMS and what is the relationship between these and antioxidants in FMS patients. In this review we will elucidate the importance of oxidative stress and antioxidants and its possible relationship with FMS. Moreover, as metal toxicity is also reported to be involved in the pathogenesis of FMS, therefore we will also try to establish the role of toxic metals in the pathogenesis of FMS.

Abstract
Some patients suffering from fibromyalgia present with clinical signs and alterations in the histopathology, immunohistochemistry and ultrastructure of the dermis similar to the Ehlers-Danlos syndrome, hypermobile type (EDSH). Some types of fibromyalgia possibly represent an undiagnosed EDSH.

Abstract
BACKGROUND Fibromyalgia (FM) is a disease of unknown etiology. Inflammation could be one of the mechanisms behind this disease. OBJECTIVES We studied the frequency and clinical relevance of metal allergy in FM patients. METHODS Fifteen female FM patients were included in the study. Metal allergy was measured by a lymphocyte transformation test, MELISA®. Ten healthy age-matched women were used as controls for in vitro studies. Reduction of metal exposure in the FM patients was achieved by replacement of dental metal restorations and by the avoidance of known sources of metal exposure. Objective health assessment was performed 5 years after treatment. Subjective health assessment was established by a questionnaire, completed 2, 5 and in some cases 10 years after the start of the study. Follow-up MELISA was also performed. RESULTS All FM patients tested positive to at least one of the metals tested. The most frequent reactions were to nickel, followed by inorganic mercury, cadmium and lead. Some healthy controls responded to inorganic mercury in vitro but most of the tests were negative. Objective examination 5 years later showed that half of the patients no longer fulfilled the FM diagnosis, 20% had improved and the remaining 30% still had FM. All patients reported subjective health improvement. This correlated with the normalisation of metal-specific responses in vitro. CONCLUSION Metal allergy is frequent in FM patients. The reduction of metal exposure resulted in improved health in the majority of metal-sensitized patients. This suggests that metal-induced inflammation might be an important risk factor in a subset of patients with FM.
