Fibromyalgia (FM) syndrome is characterized by physical symptoms such as pain, fatigue, and sleep disorders, as well as mental symptoms that include depression, mental exhaustion, and a sense of hopelessness. The current study focuses on 3 main strategies used by FM patients living in communities in the Gaza Envelope who are under constant security threat: problem-oriented, emotion-oriented, and avoidance.The study introduces a groundbreaking intervention program based on a fibrotherapy intervention (FTI) program developed at the Rehabilitation Center "Ezra Le'Marpeh" led by Rabbi Avraham Elimelech Firer. The cohort study sample consists of 96 women who have been diagnosed with FM and have participated in the FTI program for 10 weeks. The study uses mixed methods of quantitative and qualitative analyses in which 16 women from the sample were interviewed. In addition to collecting demographic information and medical data, the study used the Brief Cope questionnaire.The findings corroborate the hypothesis and show a difference between the coping patterns of FM patients before and after the intervention.The sharing experience as a part of the FTI program can lead FM patients to adopt positive disease management strategies, which may improve their quality of life.

Background: Fibromyalgia (FM) is a disease characterized by widespread musculoskeletal chronic pain that impairs the patient’s quality of life and is considered a somatization disorder. The symptoms of the disease also affect the patient mentally, mainly since invisible pain is the only thing that indicates its existence. A typical symptom that characterizes FM patients is the lack of acceptance of the disease since its pathophysiology is not elucidated, hence the deficiencies in its management, or rather, cognitively, the belief that there is no disease to manage. The current paper aims to shed light on the new treatment methods at a holistic level, that is, cognitive, physical, and pharmacological therapies. Method: A literature review was carried out that discusses treatment methods that help alleviate the pain, accept it, and manage the symptoms of the disease. Results: FM symptoms can be treated by taking a broad view of treatment that will include a response to the mind through pain management, response to the body through physical activity, and response to the pain through pharmacological treatment. Conclusions: Today, there is an evolutionary view that accepts FM and chronic pain diseases as syndromes in which the pain is the disease; therefore, the response to this disease can be applied through three channels: physical, bodily, and mental.

Research into the neurobiological and psychosocial mechanisms involved in fibromyalgia has progressed remarkably in recent years. Despite this, current accounts of fibromyalgia fail to capture the complex, dynamic, and mutual crosstalk between neurophysiological and psychosocial domains. We conducted a comprehensive review of the existing literature in order to: a) synthesize current knowledge on fibromyalgia; b) explore and highlight multi-level links and pathways between different systems; and c) build bridges connecting disparate perspectives. An extensive panel of international experts in neurophysiological and psychosocial aspects of fibromyalgia discussed the collected evidence and progressively refined and conceptualized its interpretation. This work constitutes an essential step towards the development of a model capable of integrating the main factors implicated in fibromyalgia into a single, unified construct which appears indispensable to foster the understanding, assessment, and intervention for fibromyalgia.

Background. Fibromyalgia syndrome (FMS), a chronic widespread pain disorder, has been associated with various models of stress, including those that are workplace-related. In a previous study, we have documented the significantly increased prevalence of FMS among schoolteachers, as well as correlating symptoms with stressful workplace-related factors. In the current study, we have focused on the specific population of kindergarten teachers and attempted to document both the prevalence of FMS symptoms among this group and the association with stress and symptoms of posttrauma. Methods. All participants in the study were working as kindergarten teachers in Israel at the time of the study. Participants responded to a questionnaire documenting FMS symptom, which included the widespread pain index (WPI) and symptom severity scale (SSS), which together constitute the suggested American College of Rheumatology (ACR) FMS diagnostic criteria. Additional items on the questionnaire documented work motivation and performance, the occurrence of workplace-related stressful events, and the presence of posttraumatic symptoms. Results. 242 participants were recruited to the current study, including 239 (98.8%) females and 3 (1.2%) males. 62 individuals (25.6%) were found to fulfill ACR FMS criteria. Significant differences in work performance were found between teachers fulfilling FMS criteria compared with those not fulfilling criteria. Thus, FMS-positive teachers reported significantly higher rates of missing workdays, leaving work early, and a lower quality of interaction with children in the kindergarten and with peers and supervisors. Motivation to work was also significantly lower among these individuals. The widespread pain index (WPI) and symptom severity scale (SSS), which together constitute the components of the FMS diagnostic criteria, were positively correlated with both stress and posttraumatic symptoms. In addition, widespread pain, disordered sleep, difficulty with concentration, and other FMS symptoms were strongly correlated with many specific stressful factors at the workplace, including the number of children in the kindergarten, interaction with parents, lack of optimal physical conditions in the classrooms, and various demands on behalf of the educational system. Conclusion. FMS symptoms were found to be highly prevalent among Israeli kindergarten teachers, at a rate that greatly exceeds the prevalence in the general Israeli population. Stressful work-related events appear to be positively associated with the occurrence of FMS symptoms and may serve as triggers for their development. Healthcare professionals treating individuals engaged in this occupation should be vigilant for the occurrence of symptoms that are clinically associated with FMS and overlapping functional disorders.

Objective To compare the concordance of the three diagnostic criteria, respectively the 2011 ACR criteria (ACR 2011 Cr), the ACR 2016 criteria (ACR 2016 Cr) and the Analgesic, Anesthetic, and Addiction Clinical Trial Translations Innovations Opportunities and Networks (ACTTION)-APS Pain Taxonomy criteria (AAPT Cr), and to explore the performance of an additional set of criteria, the modified Fibromyalgia Assessment Status (FAS 2019 modCr), in the diagnosis of FM syndrome. Methods Consecutive patients with chronic widespread pain, referred by the primary care setting, underwent rheumatologic assessment that established the presence or not of FM and were investigated through the four sets of proposed criteria. For the FAS 2019 modCr, discriminant validity to distinguish patients with FM and non-FM was assessed with receiver operating characteristic curve analysis. Results A total of 732 (405 with FM and 327 with other common chronic pain problems) patients were evaluated. Against the clinical diagnosis of FM, the sensitivity, specificity and correct classification were, respectively: 79.8, 91.7 and 85.1% for ACR 2011 Cr; 78, 90.5 and 83.6% for the ACR 2016 Cr; and 73.8, 91.7 and 81.8% for the AAPT Cr. The alternative set, proposed on the FAS 2019 modCr, provided a maximal diagnostic accuracy with a score ≥20 (Youden’s index), with a sensitivity of 84.2%, specificity 89.0% and positive likelihood ratio 7.65. Conclusion There is a considerable agreement between criteria-based diagnoses of FM, although the AAPT Cr perform least well in terms of percentage of correct classification. The FAS 2019 modCr had comparable characteristics.

This study sought to examine whether the sense of coherence (SOC) among fibromyalgia (FM) increased after participation in a fibrotherapy intervention programme (FTI) and whether SOC among FM patients who changed their coping strategies to problem-oriented coping, increased. The study was conducted among FM female patients who are exposed to security threats in order to examine the coping resources of these patients.96 female patients aged 19-75 diagnosed with FM enrolled in the FTI programme led by Rabbi Firer in Sderot, Israel. Of this sample, 16 were interviewed for the qualitative part.The quantitative analysis found that there was a change in the level of SOC before and after participation in FTI and that an increasing trend in SOC was observed after participating in FTI, thus, confirming the first hypothesis. Also, a problem-oriented coping pattern emerged after participating in FTI. The data further show that according to the second study hypothesis, among problem-oriented patients, the levels of psychological distress decreased, and the physiological indicators (endurance) increased as well as an improved functional ability. In other words, following FTI, there was a positive improvement in the physical and mental health scores of problem-oriented patients. Participation in FTI has resulted in a comprehensive health improvement among the study sample.Participation in FTI improved FM patients' SOC and coping strategies and provided them with tools to understand the meaning of the disease and thereby accept and manage it.

Aim: To investigate the health care utilization and drug consumption of patients with fibromyalgia (FM). Materials and Methods: This is a cross-sectional study using the Clalit Health Care database. Clalit is the largest HMO in Israel, serving more than 4.4 million enrollees. We identified FM patients and age and sex-matched controls. Indicators of healthcare utilization and drug consumption were extracted and analyzed for both groups. Results: The study included 14,296 FM patients and 71,324 controls. The mean age was 56 years, with a female predominance of 92%. The mean number of visits across of all healthcare services (hospitalizations, emergency department visit, general practitioner clinic visits, rheumatology clinic visits and pain clinic visits) and the mean difference (MD) were significantly higher for FM patients compared to controls (MD 0.66, p

Fibromyalgia (FM) is a common chronic pain disorder that presents diagnostic challenges for clinicians. Several classification, diagnostic and screening criteria have been developed over the years, but there continues to be a need to develop criteria that reflect the current understanding of FM and are practical for use by clinicians and researchers. The Analgesic, Anesthetic, and Addiction Clinical Trial Translations Innovations Opportunities and Networks (ACTTION) public-private partnership with the U.S. Food and Drug Administration (FDA) and the American Pain Society (APS) initiated the ACTTION-APS Pain Taxonomy (AAPT) to develop a diagnostic system that would be clinically useful and consistent across chronic pain disorders. The AAPT established an international FM working group consisting of clinicians and researchers with expertise in FM to generate core diagnostic criteria for FM and apply the multidimensional diagnostic framework adopted by AAPT to FM. The process for developing the AAPT criteria and dimensions included literature reviews and synthesis, consensus discussions, and analyses of data from large population-based studies conducted in the United Kingdom. The FM working group established a revised diagnosis of FM and identified risk factors, course, prognosis, and pathophysiology of FM. Future studies will assess the criteria for feasibility, reliability, and validity. Revisions of the dimensions will also be required as research advances our understanding of FM. PERSPECTIVE: The ACTTION-APS FM taxonomy provides an evidence-based diagnostic system for FM. The taxonomy includes diagnostic criteria, common features, comorbidities, consequences, and putative mechanisms. This approach might improve the recognition of FM in clinical practice.

FM is a chronic pain disorder which manifests with chronic widespread pain, accompanied by fatigue and mood and sleep disorders. The current concept views FM as the consequence of central nervous system malfunction resulting in amplification of pain transmission and interpretation. Our understanding of fibromyalgia has made significant advances over the past decade, still despite extensive research this disease’s clear etiology and pathophysiology is yet to be discovered. Current knowledge indicates several triggers and possible etiologies to the development of FM. Past research has demonstrated a role for polymorphisms of genes with clear familial aggregation and genetic underpinning in the etiopathogenesis of FM. Furthermore, the role of stressful events has been well established in the literature, depicting either mechanical stress as injury or psychological stress including early life trauma as trigger and predisposition for future development of FM. Not only recent studies exhibited development of FM in the workplace in correlation with stress, low work performance, and even posttraumatic stress disorder (PTSD). Moreover, it is known that other various external stimuli such as infections or vaccinations may contribute to the development of the FM syndrome.

Fibromyalgia is a common pain syndrome treated by physicians of many disciplines and presents with many co-morbidities. We reviewed the complexities in assessing disabilities in fibromyalgia patients and the complex interrelationships between patients, their working places, and the medical community regarding preserving productivity. Flexibility is essential to keep the patients functional and productive. Job loss is costly to both society and patients and joint measures are needed to prevent unemployment.

Diffuse Idiopathic Skeletal Hyperostosis (DISH) is considered a metabolic condition, characterized by new bone formation affecting mainly at entheseal sites. Enthesitis and enthesopathies occur not only in the axial skeleton but also at some peripheral sites, and they resemble to some extent the enthesitis that is a cardinal feature in spondyloarthritis (SpA), which is an inflammatory disease. We review the possible non-metabolic mechanism such as inflammation that may also be involved at some stage and help promote new bone formation in DISH. We discuss supporting pathogenic mechanisms for a local inflammation at sites typically affected by this disease, and that is also supported by imaging studies that report some similarities between DISH and SpA. Local inflammation, either primary or secondary to metabolic derangements, may contribute to new bone formation in DISH. This new hypothesis is expected to stimulate further research in both the metabolic and inflammatory pathways in order to better understand the mechanisms that lead to new bone formation. This may lead to development of measures that will help in earlier detection and effective management before damage occurs.

Research into the neurobiological and psychosocial mechanisms involved in fibromyalgia (FM) has progressed remarkably in recent years. Despite this, currents accounts of FM fail to capture the complex, dynamic and mutual crosstalk between neurophysiological and psychosocial domains. We conducted a comprehensive review of the existing literature in order to synthesise current knowledge on FM, explore and highlight multi-level links and pathways among different systems and build bridges between existing approaches. An extensive panel of international experts in neurophysiology and psychosocial aspects of FM discussed the collected evidence and progressively refined and conceptualized its interpretation. Fibromyalgia is a complex condition resulting from the dynamic interplay between multiple systems and processes. We provided an updated overview of the most relevant observations in FM to date as well as the potential pathways by which they exert they are related and exert their mutual influence, to produce the manifestations commonly associated with FM. This review constituted the first step towards and supported the development of a much needed model capable of integrating the main factors implicated in FM into a single, unified model that may prove valuable in understanding and managing FM.

PurpeseTo determine whether higher pain thresholds are associated with better performance in long-distance runners.DesignCross-sectional study.MethodsSeventy participants, divided into groups of fast and non-fast runners according to peak results in a 10km run. Main Outcome Measures, Cold pressor test.ResultsOf the 70 subjects, 28 were in the fastest group (less than 39 minutes in a 10km run) and 42 in the non-fast group. The faster group was characterized with older age (34.0±8.5 vs. 29.5±5.7, p=0.01), greater mean weekly running time (5.5 (0-17) vs. 2 (0- 10), pp=0.05)]. In a multivariable analysis longer cold pressor time was associated with faster 10Km run (O.R 1.01, 95% C.I 1.00-1.01).ConclusionsIt seems that higher pain thresholds play an important role in the superior ability of long distance runners.

Stress has extensively been shown to trigger fibromyalgia syndrome (FM). Nursing is associated with high levels of stress. Our hypothesis was that nurses suffer from an increased prevalence of FM symptoms, and that these symptoms correlate with the levels of stress to which they are exposed in the course of their occupation.The study was conducted as a targeted survey distributed to nursing staff in Soroka University Medical Centre, Beer-Sheva, Israel. Participants were asked to answer a questionnaire evaluating symptoms of FM, based on the current diagnostic criteria, which include the widespread pain index (WPI) and the symptom severity scale (SSS). Participants were further questioned regarding stressful experiences during their work and about post-traumatic symptoms as well as regarding work performance and motivation.206 participants completed the study questionnaire (84.5% females and 15.5% males). Twenty (9.7%) participants of the sample fulfilled criteria for diagnosis of FM reaching rates among females and males of 10.9% and 3.1% respectively. The prevalence of FM in our study was related to age with the highest prevalence in the older age groups (p=0.012). FM symptoms were strongly correlated with work related stress and were strongly correlated with Post Traumatic Stress Disorder (PTSD)-related symptoms. Work-performance parameters did not show a significant correlation with FM parameters.FM is highly prevalent among nursing staff. Our findings point towards the possibility that work-related stress and traumatic events may play a major role in the development of FM symptoms among nurses. With aging this association is more significant.

The FAS 2019 modCr had comparable characteristics.

Fibromyalgia syndrome (FM), characterised by widespread pain and fatigue, has frequently been associated with stress in various models, including workplace related stress. In the current study we have evaluated the prevalence of FM symptoms among Israeli school teachers and have attempted to correlate such symptoms with work-related stress.Individuals, all currently employed as school teachers in Israel, were recruited to the study. Participants were asked to answer a questionnaire evaluating symptoms of FM, based on the current diagnostic criteria, which include the widespread pain index (WPI) and the symptom severity scale (SSS). Participants were further questioned regarding stressful experiences during their work and about post-traumatic symptoms as well as regarding work performance and motivation.321 participants were recruited (79.4% female, 20.6 male). 30 individuals (9.3%) of the sample fulfilled current criteria for a diagnosis of FM, with a rate of 11.4% among females and 1.5% among males. While specific symptoms such as fatigue and irritable bowel symptoms were negatively correlated with work performance, no significant difference was found between teachers with or without fibromyalgia regarding work attendance and performance. FM symptoms were strongly correlated with work-related stress and were strongly correlated with post-traumatic stress disorder (PTSD) related symptoms. Motivation to work was significantly lower among teachers fulfilling FM criteria, but other performance-related parameters did not differ between teachers fulfilling or not fulfilling FM criteria.Fibromyalgia symptoms are highly prevalent among Israeli school teachers, and may be related to stress encountered in the classroom. These results are relevant both for physicians treating individuals involved in educational careers as well as for educators and decision-makers involved in planning and managing educational strategies.

Diffuse idiopathic skeletal hyperostosis (DISH) is a well-recognised entity characterised by calcifications and ossifications of the entheses affecting mainly the spine and peripheral sites. DISH is still insufficiently investigated and understood. The objective of this report is to highlight the present limitations of our understanding of the condition and suggest future research paths.

Fibromyalgia syndrome (FMS) is a common and intriguing condition, manifest by chronic pain and fatigue. Although the pathogenesis of FMS is not yet completely understood, predicting the future development of FMS and chronic pain is a major challenge with great potential advantages, both from an individual as well as an epidemiological standpoint. Current knowledge indicates a genetic underpinning for FMS, and as increasing data are accumulated regarding the genetics involved, the prospect of utilizing these data for prediction becomes ever more attractive. The co-existence of FMS with multiple other functional disorders indicates that the clinical identification of such symptom constellations in a patient can alert the physician to the future development of FMS. Hypermobility syndrome is another clinical (as well as genetic) phenotype that has emerged as a risk factor for the development of FMS. Stressful events, including early life trauma, are also harbingers of the future development of FMS. Functional neuroimaging may help to elucidate the neural processes involved in central sensitization, and may ultimately also evolve into markers of predictive value. Last but not least, obesity and disturbed sleep are clinical (inter-related) features relevant for this spectrum. Future efforts will aim at integrating genetic, clinical and physiological data in the prediction of FMS and chronic pain.

Diffuse idiopathic skeletal hyperostosis (DISH) is a systemic condition characterized by the ossification and calcification of ligaments and entheses. DISH is observed on all continents and in all races, but most commonly in men over 50 years of age. Although DISH is asymptomatic in most individuals, the condition is often an indicator of underlying metabolic disease, and the presence of spinal or extraspinal ossifications can sometimes lead to symptoms including pain, stiffness, a reduced range of articular motion, and dysphagia, as well as increasing the risk of unstable spinal fractures. The aetiology of DISH is poorly understood, and the roles of the many factors that might be involved in the development of excess bone are not well delineated. The study of pathophysiological aspects of DISH is made difficult by the formal diagnosis requiring the presence of multiple contiguous fully formed bridging ossifications, which probably represent advanced stages of DISH. In this Review, the reader is provided with an up-to-date discussion of the epidemiological, aetiological and clinical aspects of DISH. Existing classification criteria (which, in the absence of diagnostic criteria, are used to establish a diagnosis of DISH) are also considered, together with the need for modified criteria that enable timely identification of early phases in the development of DISH.

ObjectiveThe current study is an innovative exploratory investigation, aiming at identifying differences in personality profiles within Fibromyalgia Syndrome (FMS) and Chronic Fatigue Syndrome (CFS) patients.MethodIn total, 344 participants (309 female, 35 male) reported suffering from FMS and/or CFS and consented to participate in the study. Participants were recruited at an Israeli FM/CFS patient meeting held in May 2013, and through an announcement posted on several social networks. Participants were asked to complete a research questionnaire, which included FMS criteria and severity scales, and measures of personality, emotional functioning, positivity, social support and subjective assessment of general health. In total, 204 participants completed the research questionnaire (40.7% attrition rate).ResultsA cluster analysis produced two distinct clusters, which differed significantly on psychological variables, but did not differ on demographic variables or illness severity. As compared to cluster number 2 (N = 107), participants classified into cluster number 1 (N = 97) showed a less adaptive pattern, with higher levels of Harm Avoidance and Alexithymia; higher prevalence of Type D personality; and lower levels of Persistence (PS), Reward dependence (RD), Cooperation, Self-directedness (SD), social support and positivity.ConclusionThe significant pattern of results indicates at least two distinct personality profiles of FM and CFS patients. Findings from this research may help improve the evaluation and treatment of FM and CFS patients, based on each patient’s unique needs, psychological resources and weaknesses, as proposed by the current trend of personalized medicine.

Objectives. To evaluate the effect of presurgical symptoms characteristic of fibromyalgia on the postsurgical outcome of patients undergoing spinal surgery. Methods. In this observational cohort study, participants were patients scheduled for spinal surgery, including cervical or lumbar laminectomy and foraminectomy. Presurgical evaluation included physical examination and manual dolorimetry. Questionnaires included the widespread pain index (WPI), symptom severity scale (SSS), and SF-36. Postsurgical evaluation performed at 10–12 weeks included questionnaires, physical examination, and dolorimetry. Results. Forty patients (21 male, 19 female) were recruited. Four patients (10%) fulfilled American College of Rheumatology (ACR) 1990 fibromyalgia; nine patients fulfilled 2010 criteria (22.5%). Overall, a significant 34% reduction in WPI was observed postsurgically ( P

Objective. To revise the definition of DISH and suggest a classification that may better represent our current knowledge of this entity allowing earlier diagnosis. Methods. Seven rheumatologists and an orthopaedic surgeon suggested a list of 63 parameters that might be included in a future classification of DISH. Participants rated their level of agreement with each item, expressed in percentages. In a second session, participants discussed each item again and re-rated all parameters. Thirty items that were granted 550% support on average were considered valid for a third round. A questionnaire listing these 30 items was mailed to 39 rheumatologists and orthopaedic surgeons worldwide with a request to answer categorically if they agreed on an item to be included as a criterion for a future classification of DISH. Items were regarded as perfect consensus when at least 95% of the respondents agreed and were regarded as consensus when at least 80% agreed. Results. There was perfect consensus for 2 (6.7%) of the 30 parameters and consensus for another 2 parameters. These items were ossification and bridging osteophytes in each of the three segments of the spine and exuberant bone formation of bone margins. Conclusion. At present there is no agreement about the inclusion of extraspinal, constitutional and metabolic manifestations in a new classification of DISH. Investigators with an interest in this condition should be encouraged to restructure the term DISH in an attempt to establish a more sophisticated definition.

Hepatitis C virus infection (HCV) is one of the best mimes in medicine. About 40-70% of patients suffering from this disorder develop at least one extra-hepatic disorder that can have a rheumatic nature (arthralgias, arthritis, vasculitis and sicca syndrome) and must be differentiated from the primitive rheumatic diseases. In addition, HCV infection can also alter the laboratory tests. Several alterations of first line laboratory tests can be usually found in both chronic HCV infection and chronic inflammatory rheumatic disorders. In the present review we analyze the interference of HCV in tests more specifically used in rheumatology: rheumatoid factor and other autoantibodies (ANA, anti-ENA, ANCA, anti-DNA, antiphospholipid, anti-CCP). In patients suffering from HCV infection, the diagnosis of connective tissue diseases (CTD) or rheumatoid arthritis (RA) should be made only when the detected symptoms or laboratory data are not inducible by HCV, otherwise only a diagnosis of "possible CTD" or "possible RA" should be considered.

Fibromyalgia (FM) is defined as chronic widespread pain (CWP) with allodynia or hyperalgesia to pressure pain, and is classified as one of the largest group of soft tissue pain syndromes. Its pathogenesis is not entirely understood, although it is currently believed to be the result of a central nervous system (CNS) malfunction that increases pain transmission and perception. There are no instrumental tests to confirm the diagnosis, but many of the differential diagnoses can be excluded by means of an extensive clinical examination and patient history. Although fibromyalgia is a recognisable clinical entity, it would seem appropriate to consider the entire range of tenderness and distress in clinic patients in order to tailor treatment on an individual basis.

Background Recent evidence suggests that genetic factors might contribute to individual differences in pain sensitivity, risk for developing clinical pain conditions and efficacy of pain treatments. The purpose of the present study was to investigate the relationship of three common haplotypes of COMT gene affecting the metabolism of catecholamines on pain sensitivity in patients with fibromyalgia (FM). Methods One hundred and thirteen FM patients and 65 age-matched healthy volunteers participated in the study. We genotyped four single-nucleotide polymorphisms (SNPs) (rs6269, rs4633, rs4818 and rs4680 or Val158Met) and identified haplotypes previously designated as low (LPS), average (APS) and high pain sensitivity (HPS). Thermal, pressure and touch thresholds were also examined using a quantitative sensory testing protocol. Results The frequency of genetic variations associated with low COMT enzyme activity was significantly higher in FM patients than in healthy volunteers. FM patients were more sensitive to experimental pain than healthy volunteers and, in particular, FM individuals with the met/met genotype (Val158Met SNP) or the HPS-APS haplotypes showing higher sensitivity to thermal and pressure pain stimuli than patients carrying the LPS haplotype or val alleles (Val158Met SNP). No differences due to genotype or haplotypes were found on non-painful touch thresholds. Conclusions According with previous research, our findings revealed that haplotypes of the COMT gene and genotypes of the Val158Met polymorphism play a key role on pain sensitivity in FM patients.

The aim of the study was to assess iron serum levels and markers of iron stores in non-anemic fibromyalgia (FM) patients and to evaluate their impact on the prevalence and clinical manifestations of FM patients. Eighty-four patients with primary FM and 87 controls were investigated. Demographic and clinical data were collected from all participants. All patients completed the fibromyalgia impact questionnaire (FIQ). Patients evaluated the effect of the disease on their daily activity (DA) and judged the severity (DS) of the disease on a 0-10 scale. Venous blood was tested for serum iron, transferrin, ferritin, and soluble transferrin receptors (sTfR). Iron deficiency was defined if any of the following were present: serum iron40 μg/dL, serum ferritin levels10 ng/mL, or sTfR levels28.1 nmol/L. Analysis at a cutoff level of serum ferritin levels ≤30 ng/mL and sTfR/ferritin ratio was also performed. Hemoglobin, iron, transferrin, sTfR, ferritin levels, and sTfR/ferritin ratios did not differ between the groups. The mean FIQ score was 57.13 ± 20.21 and the DA and DS scores were 6.79 ± 2.97 and 6.74 ± 3.09, respectively. No correlations were found between the parameters studied and the FIQ or its ten individual items. Thirty-eight controls (43.7%) and 23 FM patients (27.4%) had ferritin levels of ≤30 (p0.04). Within the FM group, lower levels were associated with lower total FIQ score and FIQ subscale scores. Patients with FM do not have reduced serum levels of iron or surrogate markers of iron stores. At present, there is no evidence to support iron supplementation in the treatment of FM.

Pharmacological treatment has been gradually enriched by a variety of compounds; however, no single drug is capable of fully managing the constellation of fibromyalgia (FM) symptoms. Currently, it is not possible to draw definite conclusions concerning the best pharmacological approach to managing FM because results of randomized clinical trials present methodological limitations and therapeutic programs are too heterogeneous for adequate comparison. However, a variety of pharmacological treatments including antidepressants, nonsteroidal anti-inflammatory drugs (NSAIDS), opioids, sedatives, muscle relaxants and antiepileptics have been used to treat FM with varying results. In this review, we will evaluate those pharmacological therapies that have produced the most significant clinical results in treating FM patients. The nature of FM suggests that an individualized, multimodal approach that includes both pharmacologic and nonpharmacologic therapies seems to be the most appropriate treatment strategy to date.

Fibromyalgia syndrome (FM) is a condition of chronic and diffuse muscular pain affecting particularly middle aged women. The aetiology of FM is not completely understood and it is currently considered a disorder of pain regulation. The most efficacious compounds include the tricyclic drugs and mixed reuptake inhibitors. Recent works suggest that the anticonvulsant medications pregabalin and gabapentin are also effective. Moreover, two serotonin and norepinephrine- reuptake inhibitors-duloxetine and milnacipran show encouraging results in treating FM symptoms. The results of clinical trials of anti-inflammatory medications have been generally disappointing, but three RCTs have found that tramadol (with or without acetaminophen) is effective in FM.

In the past decade, major progress has been made in our understanding of fibromyalgia syndrome (FMS). Various triggers have been implicated as contributing to symptom development in FMS when genetically susceptible individuals are challenged. A substantial amount of data points towards the association between trauma and chronic widespread pain/fibromyalgia syndrome (CWP/FMS). There is abundant data suggesting that the pathogenesis of CWP/FMS might be related to cervical spine injury. Furthermore, several persistent local pain conditions may progress to CWP/FMS. These conditions may share a common pathogenic mechanism namely, central sensitisation. Physical trauma and emotional trauma co-exist in many traumatic events and may interact in the pathogenesis of CWP/FMS.

To investigate pregnancy outcome of patients with fibromyalgia syndrome (FMS).A retrospective cohort study comparing pregnancies of women with and without FMS was conducted. Multivariable logistic regression models was performed to control for confoundersDeliveries of 112 women with FMS were compared with a control group of 487 deliveries of women without FMS. Parturients with FMS had higher rates of intrauterine growth restriction (IUGR; 7.1% vs. 1.0%, p = 0.001), recurrent abortions (9.8% vs. 1.8%, p0.001), gestational diabetes mellitus (14.3% vs. 7%, p = 0.012), and polyhydramnios (12.5% vs. 1.6%, p0.001). These patients had lower rates of preterm deliveries (PTD; 6.3% vs. 16.7%, p = 0.018). No significant differences were noted between the groups regarding the rates of cesarean deliveries (CD) (15.2% vs. 21.2%, p = 0.149) and perinatal outcomes such as low Apgar scores (7) at 1 and 5 min (4.5% vs. 6.7%, p = 0.292 and 1.2% vs. 0.6%, p = 0.372; respectively). Using two multiple logistic regression models, the positive association between FMS and IUGR (adjusted OR = 4.1, 95% CI 1.2-13.2; p = 0.02) and the negative association with PTD (OR = 0.3, 95% CI 0.2-0.6; p = 0.001) remained significant.FMS is an independent risk factor for intrauterine growth restriction. Nevertheless, it is associated with lower rates of preterm deliveries.

Background/Aims There is significant co-morbidity between irritable bowel syndrome (IBS) and fibromyalgia syndrome (FMS). However, FMS is diagnosed by physical examination, which limits the conduct of co-morbidity studies in a large population-based study. The purpose of this study was to determine the diagnostic validity of a new symptom-based criteria in patients with FMS and/or IBS using the American College of Rheumatology (ACR) criteria as a gold standard. Methods The study participants consisted of women with FMS (n=30), IBS (n=27) and controls (n=28). A new symptom-based diagnostic criteria for FMS comprised a regional pain scale and a visual analogue scale for fatigue. All subjects underwent a physical examination for FMS (ACR criteria) and structured questionnaires of regional pain scale and visual analogue scale for fatigue. A fibromyalgia intensity score was calculated and thresholds of tenderness were determined by a dolorimeter. Results The number of participants diagnosed with FMS in the entire study population (n=85) was 31 by the new criteria. Compared to the ACR, the sensitivity of the new criteria was 82.9%, specificity 96.0%, positive predictive value 93.5% and negative predictive value 88.9%. In addition, new criteria were useful for the diagnosis of FMS among the subjects with IBS. A fibromyalgia intensity score was significantly correlated with the threshold of tenderness (r=-0.62, P

Objective.To investigate the degree of nonarticular tenderness and functional status in patients with diffuse idiopathic skeletal hyperostosis (DISH). We assessed these variables’ correlation with their clinical, radiographic, and constitutional measurements and with metabolic syndrome (MS).Methods.Eighty-seven patients with DISH were compared with 65 controls without DISH. Examination of nonarticular tenderness was performed by thumb palpation. Tenderness was scored for the 18 fibromyalgia tender points (TP), and 4 control points. Nonarticular tenderness was expressed by the number of TP and by the total tenderness score (TTS). The Short Health Assessment Questionnaire (HAQ II) was administered to all participants. Clinical and laboratory data were collected from all patients. Patients were classified as having MS by both the National Cholesterol Education Program and World Health Organization definitions.Results.There was a statistically significant difference in TTS between controls and patients with DISH. The mean tenderness of many individual TP was significantly higher in the DISH group compared with the control group. TP counts, TTS, and body mass index (BMI) positively correlated with the HAQ II. There was a linear trend in intensity of T-spine bony bridges (BB) and the total number of TP as well as many individual TP. Patients with DISH were more likely to be affected by MS. No correlation was found between TP count, TTS, and MS.Conclusion.Patients with DISH have a lower pain threshold than patients who do not have DISH. TP count and TTS correlate with the functional status, BMI, waist circumference, and high-grade BB. No correlation was observed between pain threshold and MS.

Fibromyalgia (FM) is a chronic condition characterized by widespread pain and diffuse tenderness along with a constellation of ancillary symptoms. The 1990 ACR criteria for classification of FM are important in enhancing much the research of FM. FM is part of a spectrum of functional somatic syndromes. FM is not a homogenous condition and several subtypes of FM had been determined. The best strategy for management of FM is to use a multidisciplinary approach to treatment using both pharmacological and non-pharmacological interventions. Tramadol, tricyclic drugs, mixed reuptake inhibitors and anticonvulsants show efficacy in this condition. Recently, three drugs: pregabalin, duloxetine and milnacipran have been approved by the FDA for treatment of FM.
