Hierarchical Clustering Applied to Chronic Pain Drawings Identifies Undiagnosed Fibromyalgia: Implications for Busy Clinical Practice. THE JOURNAL OF PAIN 2024; 25:104489. [PMID: 38354967 PMCID: PMC11180596 DOI: 10.1016/j.jpain.2024.02.003] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/19/2023] [Revised: 01/29/2024] [Accepted: 02/01/2024] [Indexed: 02/16/2024]
Abstract
Currently-used assessments for fibromyalgia require clinicians to suspect a fibromyalgia diagnosis, a process susceptible to unintentional bias. Automated assessments of standard patient-reported outcomes (PROs) could be used to prompt formal assessments, potentially reducing bias. We sought to determine whether hierarchical clustering of patient-reported pain distribution on digital body map drawings predicted fibromyalgia diagnosis. Using an observational cohort from the University of Pittsburgh's Patient Outcomes Repository for Treatment registry, which contains PROs and electronic medical record data from 21,423 patients (March 17, 2016-June 25, 2019) presenting to pain management clinics, we tested the hypothesis that hierarchical clustering subgroup was associated with fibromyalgia diagnosis, as determined by ICD-10 code. Logistic regression revealed a significant relationship between the body map cluster subgroup and fibromyalgia diagnosis. The cluster subgroup with the most body areas selected was the most likely to receive a diagnosis of fibromyalgia when controlling for age, gender, anxiety, and depression. Despite this, more than two-thirds of patients in this cluster lacked a clinical fibromyalgia diagnosis. In an exploratory analysis to better understand this apparent underdiagnosis, we developed and applied proxies of fibromyalgia diagnostic criteria. We found that proxy diagnoses were more common than ICD-10 diagnoses, which may be due to less frequent clinical fibromyalgia diagnosis in men. Overall, we find evidence of fibromyalgia underdiagnosis, likely due to gender bias. Coupling PROs that take seconds to complete, such as a digital pain body map, with machine learning is a promising strategy to reduce bias in fibromyalgia diagnosis and improve patient outcomes. PERSPECTIVE: This investigation applies hierarchical clustering to patient-reported, digital pain body maps, finding an association between body map responses and clinical fibromyalgia diagnosis. Rapid, computer-assisted interpretation of pain body maps would be clinically useful in prompting more detailed assessments for fibromyalgia, potentially reducing gender bias.

Abstract
OBJECTIVE To assess the burden of illness of people with fibromyalgia (FM) and their spouses compared with selected match populations in Denmark. METHODS Population-based, cohort case-control study using data from Danish registries from 1994 to 2021. Individuals with an FM diagnosis were identified from the National Patient Register (2008-2019) and randomly matched to a 1:4 general population comparator. Spouses or persons co-living with subjects with FM at the time of diagnosis were compared with matched comparator spouses. Healthcare and societal costs, socioeconomic status and occurrence of comorbidities were evaluated for subjects with FM, spouses and controls. RESULTS 9712 subjects with FM (94.9% females, mean age 50 years) and 5946 spouses were included. At year of diagnosis, subjects with FM had significantly more comorbidities compared with controls, including significantly more comorbid rheumatic disorders. The highest risk at the time of FM diagnosis was a comorbid diagnosis of ankylosing spondylitis (OR 7.0, 95% CI 4.9 to 10.0). Significantly more comorbidities were also observed in spouses. Subjects with FM and spouses had higher healthcare and public transfer costs and lower income from employment at all timepoints. Loss of income from employment in subjects with FM occurred years before establishment of the FM diagnosis. The employment rate after diagnosis was 22%. 10 years after the FM diagnosis, 50% received disability pension as compared with 11% of matched controls. The observed net average increased societal cost for subjects with FM amounted to €27 193 per patient-year after diagnosis. CONCLUSION FM has major health and socioeconomic consequences for patients, their partners and society and call for improved healthcare strategies matching patients' needs.

Abstract
OBJECTIVES The etiology of fibromyalgia (FM) is disputed, and there is no established cure. Quantitative data on how this may affect patients' healthcare experiences are scarce. The present study aims to investigate FM patients' pain-related healthcare experiences and explore factors associated with high satisfaction and pain relief. METHODS An anonymous, online, and patient-administered survey was developed and distributed to members of the Norwegian Fibromyalgia Association. It addressed their pain-related healthcare experiences from both primary and specialist care. Odds ratios for healthcare satisfaction and pain relief were estimated by binary logistic regression. Directed acyclic graphs guided the multivariable analyses. RESULTS The patients (n = 1,626, mean age: 51 years) were primarily women (95%) with a 21.8-year mean pain duration and 12.7 years in pain before diagnosis. One-third did not understand why they had pain, and 56.6% did not know how to get better. More than half had not received satisfactory information on their pain cause from a physician, and guidance on how to improve was reported below medium. Patients regretted a lack of medical specialized competence on muscle pain and reported many unmet needs, including regular follow-up and pain assessment. Physician-mediated pain relief was low, and guideline adherence was deficient. Only 14.8% were satisfied with non-physician health providers evaluating and treating their pain, and 21.5% were satisfied (46.9% dissatisfied) with their global pain-related healthcare. Patients' knowledge of their condition, physicians' pain competence and provision of information and guidance, agreement in explanations and advice, and the absence of unmet needs significantly increased the odds of both healthcare satisfaction and pain relief. CONCLUSIONS Our survey describes deficiencies in FM patients' pain-related healthcare and suggests areas for improvement to increase healthcare satisfaction and pain relief.

Impact of Vagus Nerve Stimulation for the Treatment of Drug-Resistant Epilepsy on Patterns of Use and Cost of Health Care Services and Pharmacotherapy: Comparisons of the 24-Month Periods Before and After Implantation. Clin Ther 2023; 45:136-150. [PMID: 36746736 DOI: 10.1016/j.clinthera.2023.01.007] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/16/2022] [Revised: 12/20/2022] [Accepted: 01/13/2023] [Indexed: 02/05/2023]
Abstract
PURPOSE This study examines the impact of vagus nerve stimulation (VNS) as treatment for drug-resistant epilepsy (DRE) on the use and cost of health care services and pharmacotherapy. METHODS Using a large US health care claims database, we identified all patients with DRE who underwent VNS between January 1, 2012 and December 31, 2019. VNS implantation date was designated as the index date, and patients had to be continuously enrolled for the 24-month period before this date (preindex period). Outcomes included all-cause and epilepsy-related hospitalization, emergency department (ED) visits, and health care costs; health care claims resulting in an epilepsy diagnosis and all claims for antiseizure medications were deemed epilepsy related. Preindex data, except care related to preoperative medical clearance for VNS, were used to estimate multivariate regression models predicting outcomes during the 24-month postindex period (follow-up period). Predicted outcomes during follow-up were then compared with observed values. As a sensitivity analysis, we also replicated all analyses among subgroups defined by comorbid depression. FINDINGS A total of 659 patients underwent VNS for DRE and met the selection criteria. For the composite outcome of all-cause hospitalizations and ED visits, observed values were 42% lower than expected during the 24-month follow-up period; for the composite outcome of epilepsy-related hospitalizations and ED visits, observed values were 49% lower (P < 0.001 for both). Observed mean total all-cause costs, inclusive of costs of the procedure, were not significantly different than expected costs by month 19 of follow-up; mean total epilepsy-related costs were comparable by month 18. Findings were similar in subgroups with and without depression, although nominally greater differences (observed - expected) were seen in those with comorbid depression. IMPLICATIONS Our findings suggest that VNS is associated with decreased risk of hospitalization or ED visits (all cause and epilepsy related) during the 2-year period subsequent to implantation and may become cost-neutral within 2 years of implantation (vs continued medical management of DRE without VNS). Although expected outcomes were estimated based on the 24-month period before implantation, the degree to which they approximated what would have happened in the absence of VNS is unknowable. Further research is needed to better understand the extend and duration of the impact of VNS on seizure frequency and severity and health-related quality of life, including its performance among those with and without comorbid depression.

Is Pilates more effective and cost-effective than aerobic exercise in the treatment of patients with fibromyalgia syndrome? A randomized controlled trial with economic evaluation. Eur J Pain 2023; 27:54-71. [PMID: 36097826 DOI: 10.1002/ejp.2039] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/02/2022] [Revised: 08/30/2022] [Accepted: 09/10/2022] [Indexed: 12/15/2022]
Abstract
BACKGROUND The aim of this study was to assess the effectiveness and cost-effectiveness of Pilates versus aerobic exercises in the treatment of patients with fibromyalgia syndrome from a societal perspective. METHODS This two-arm randomized controlled trial with blinded assessor and economic evaluation included 98 patients diagnosed with fibromyalgia syndrome using the American College of Rheumatology 2010 criteria, aged between 20 and 75 years, and pain intensity ≥3 points in the Pain Numerical Rating Scale. Patients were randomly allocated into the aerobic or Pilates group. Treatment was performed twice a week for 8 weeks. The primary outcome was the impact of fibromyalgia measured 8 weeks after randomization. Cost-effectiveness and cost-utility analyses were conducted for the impact of fibromyalgia and quality-adjusted life-years (QALYs), respectively, with a 12-month time horizon. RESULTS There was no difference between the groups for the impact of fibromyalgia (MD: 6.5 points; 95% CI: -1.8 to 14.9). The incremental cost-effectiveness ratio showed that 1-point increase in the impact of fibromyalgia was on average associated with a societal cost of £56 for the Pilates group compared to the aerobic group. The cost-utility analysis showed that the Pilates group had a 0.71 probability of being cost-effective at a willingness-to-pay of £30,000 per QALY gained. CONCLUSION There was no significant difference between groups for the impact of fibromyalgia. Pilates was not cost-effective compared to aerobic exercises for the impact of fibromyalgia. However, Pilates seemed to be the preferred option of treatment considering QALYs, although it depends on the willingness-to-pay threshold. SIGNIFICANCE Pilates showed to be a safe and effective alternative for the treatment of patients with fibromyalgia syndrome. Pilates presented similar results for the impact of fibromyalgia and superior results for pain relief compared to aerobic exercises, a highly recommended intervention for the treatment of fibromyalgia syndrome. Pilates was not cost-effective compared to aerobic exercises for the impact of fibromyalgia. However, Pilates seemed to be a cost-effective intervention for QALYs, depending on the decision-maker's willingness-to-pay threshold.

Abstract
OBJECTIVE To prevent the impairment of fibromyalgia patients due to harmful actions in daily clinical practice that are potentially avoidable. METHODS A multidisciplinary team identified the main areas of interest and carried out an analysis of scientific evidence and established recommendations based on the evidence and "formal evaluation" or "reasoned judgment" qualitative analysis techniques. RESULTS A total of 39 recommendations address diagnosis, unsafe or ineffective treatment interventions and patient and healthcare workers' education. This part I shows the first 27 recommendations on the first 2 areas. CONCLUSIONS Establishing a diagnosis improves the patient's coping with the disease and reduces healthcare costs. NSAIDs, strong opioids and benzodiazepines should be avoided due to side effects. There is no good evidence to justify the association of several drugs. There is also no good evidence to recommend any complementary medicine. Surgeries show a greater number of complications and a lower degree of patient satisfaction and therefore should be avoided if the surgical indication is not clearly established.

Abstract
BACKGROUND Cost-utility analysis uses utility indexes to assess treatment effects. Some discrepancies between different utility indexes instruments are suggested and need to be identified in health conditions not yet investigated. OBJECTIVE To compare different utility indexes instruments in Brazilian patients with fibromyalgia and identify variables associated with these instruments. METHODS Impact of fibromyalgia (Fibromyalgia Impact Questionnaire [FIQ]) and utility indexes (Short-Form 6 Dimensions [SF-6D], EuroQol 5 Dimensions [EQ-5D], and EuroQol - Visual Analogue Scale [EQ-VAS]) were assessed in 97 patients with fibromyalgia at baseline, 8-week (after an exercise-based intervention), and 6- and 12-month follow-up. Construct validity and responsiveness of the utility indexes instruments were compared. Multiple regression models were used to verify the variables associated with the utility indexes instruments. RESULTS Construct validity analysis showed that FIQ presented moderate correlation with the SF-6D, the EQ-5D, and the EQ-VAS (r=-0.43, -0.41, -0.30, respectively, all p < .01). There was a moderate correlation between the SF-6D and the EQ-5D (r = 0.51, p < .001), moderate correlation between the SF-6D and the EQ-VAS (r = 0.41, p < .001), and no correlation between the EQ-VAS and the EQ-5D. The EQ-5D was responsive at the 8-week and 6-month follow-up, the SF-6D was responsive only at 6-month follow-up and the EQ-VAS was not responsive. The FIQ was associated with the EQ-5D and the SF-6D indexes, and symptom duration and depression with the EQ-VAS index. CONCLUSION The EQ-5D better assessed the clinical change in patients with fibromyalgia. Furthermore, impact of fibromyalgia, symptom duration, and depression seem to be associated with the utility indexes.

Abstract
International treatment recommendations for fibromyalgia (FM) highlight the importance of adapted physical activity (APA) combined with patient education. Cognitive and behavioral therapies as well as an interdisciplinary approach can be proposed for more complex or severe clinical situations, with a biopsychosocial vision of rehabilitation. To personalize the rehabilitation's therapeutic approach, a clinician can use simple and validated instruments for measuring physical performance that will highlight levels of physical conditioning, which range from low to very low in FM patients. Several systematic reviews and meta-analyses have found strong evidence that supervised aerobic and resistance-training programs reduce the pain intensity and significantly improve the quality of life and the physical and psychological functioning of female FM subjects. These therapeutic approaches appear safe and promising in terms of cost-effectiveness and should be the subject of more randomized controlled trials among male FM subjects and adolescents.

RESULTS A total of 39 recommendations address diagnosis, unsafe or ineffective treatment interventions and patient and healthcare workers' education. This part I shows the first 27 recommendations on the first 2 areas. CONCLUSIONS Establishing a diagnosis improves the patient's coping with the disease and reduces healthcare costs. NSAIDs, strong opioids and benzodiazepines should be avoided due to side effects. There is no good evidence to justify the association of several drugs. There is also no good evidence to recommend any complementary medicine. Surgeries show a greater number of complications and a lower degree of patient satisfaction and therefore should be avoided if the surgical indication is not clearly established.

Abstract
Small fiber neuropathy (SFN) is a type of peripheral neuropathy that occurs from damage to the small A-delta and C nerve fibers that results in the clinical condition known as SFN. This pathology may be the result of metabolic, toxic, immune-mediated, and/or genetic factors. Small fiber symptoms can be variable and inconsistent and therefore require an objective biomarker confirmation. Small fiber dysfunction is not typically captured by diagnostic tests for large-fiber neuropathy (nerve conduction and electromyographic study). Therefore, skin biopsies stained with PGP 9.5 are the universally recommended objective test for SFN, with quantitative sensory tests, autonomic function testing, and corneal confocal imaging as secondary or adjunctive choices. Fibromyalgia (FM) is a heterogenous syndrome that has many symptoms that overlap with those found in SFN. A growing body of research has shown approximately 40-60% of patients carrying a diagnosis of FM have evidence of SFN on skin punch biopsy. There is currently no clearly defined phenotype in FM at this time to suggest whom may or may not have SFN, though research suggests it may correlate with severe cases. The skin punch biopsy provides an objective tool for use in quantifying small fiber pathology in FM. Skin punch biopsy may also be repeated for surveillance of the disease as well as measuring response to treatments. Evaluation of SFN in FM allows for better classification of FM and guidance for patient care as well as validation for their symptoms, leading to better use of resources and outcomes.

Abstract
BACKGROUND One-third of primary care providers (PCPs) refer patients with fibromyalgia or chronic pain (FM/CP) to specialist care, typically rheumatology. Yet, comprehensive data on the quality of rheumatology care for patients with FM/CP are currently lacking. METHODS Records of patients referred for rheumatology consultation for FM/CP and seen at a single academic centre between 2017 and 2018 were extracted by retrospective chart review. Variables were diagnostic accuracy (at referral vs consultation), resource utilisation (investigations, medications, medical and allied health referral), direct costs (physician billing, staff salary, investigation fees) and access (consult wait time). Patient experience and referring PCP experience surveys were administered. RESULTS 79 charts were identified. Following consultation, 81% of patients (n=64) maintained the same diagnosis of FM/CP, 19% (n=15) were diagnosed with regional pain and 0% of patients (n=0) were diagnosed with an inflammatory arthritis or connective tissue disease. Investigations were ordered for 37% of patients (n=29), medication prescribed for 10% (n=8) and an allied health referral provided for 54% (n=43). Direct costs totalled $19 745 (average $250/consult; range $157-$968/consult). Consultation wait time averaged 184 days (range 62-228 days). Out of the seven (64%) responses to the patient experience survey, 86% of patients (n=6) were satisfied with provider communication but the consultation 'definitely' met the expectations of only 57% (n=4). The PCP survey returned an insufficient response rate. CONCLUSIONS This study found that no patient referred to rheumatology care for FM/CP was diagnosed with an inflammatory arthritis or connective tissue disease. Furthermore, patients with FM/CP experience lengthy wait times for rheumatology care which delay their management of chronic pain. Interdisciplinary and collaborative healthcare models can potentially provide higher quality care for patients with FM/CP.

Abstract
Fibromyalgia is the most common of the central sensitivity syndromes affecting 2–5% of the adult population in the United States. This pain amplification syndrome has enormous societal impact as measured by work absenteeism, decreased work productivity, disability and injury compensation and over-utilization of healthcare resources. Multiple studies have shown that early diagnosis of this condition can improve patient outlook and redirect valuable healthcare resources towards more appropriate targeted therapy. Efforts have been made towards improving diagnostic accuracy through updated criteria. The search for biomarkers for diagnosis and verification of Fibromyalgia is an ongoing process. Inadequacies with current diagnostic criteria for this condition have fueled these efforts for identification of a reproducible marker that can verify this disease in a highly sensitive, specific and reproducible manner. This review focuses on areas of research for biomarkers in fibromyalgia and suggests that future efforts might benefit from approaches that utilize arrays of biomarkers to identify this disorder that presents with a diverse clinical phenotype.

Abstract
Introduction: Fibromyalgia represents the most prevalent of the group of conditions that are known as central sensitivity syndromes. Approximately 2-5% of the adult population in the United States is affected by Fibromyalgia. This pain amplification syndrome has an enormous economic impact as measured by work absenteeism, decreased work productivity, disability and injury compensation, and over-utilization of healthcare resources. Multiple studies have shown that early diagnosis of this condition can improve patient outlook, and redirect valuable health care resources toward more appropriate targeted therapy. Efforts have been made toward improving diagnostic accuracy through updated criteria. Areas Covered: Reviewed here are 1) reasons for the need for more accurate diagnosis of Fibromyalgia, (2) a review of the evolution of Fibromyalgia to current times, and (3) the proliferation of currently available diagnostic criteria and problems related to each of them. From initial literature review until October 2020, PubMed, Embase, and Scopus were searched for applicable literature. Expert Opinion: A discussion of ongoing efforts to obtain a biomarker to enhance diagnostic accuracy concludes this review. A need to include rheumatologists as part of the care team of patients with Fibromyalgia is emphasized.

Abstract
Introduction: Psychological processes can play an important role in the expression and clinical impact of fibromyalgia.Objective: To investigate the association between the severity of pain and disability and psychological factors in patients with fibromyalgia.Methods: The following outcomes were assessed in 104 patients with fibromyalgia: pain intensity, using the Pain Numerical Rating Scale; disability, using the Patient-Specific Functional Scale; depression, using the Beck Depression Scale; anxiety, using the State-Trait Anxiety Inventory; kinesiophobia, using the Tampa Scale for Kinesiophobia; pain catastrophizing, using the Pain Catastrophizing Scale; beliefs and attitudes toward pain, using the Survey of Pain Attitudes; and the occurrence of abuse during some stage of life. Statistical analysis was performed using SPSS version 15. Initially, a simple regression analysis was performed between the dependent variables (pain and disability) and the other variables with a significance level of p ≤ 0.20, and then a multiple regression analysis was performed with a significance level of p ≤ 0.05.Results: Depression was found to be associated with pain severity (β = 0.07 [95% CI: 0.02 to 0.11], p = .00), and kinesiophobia was found to be associated with disability severity (β = -0.06 [95% CI: -0.09 to -0.02], p = .00). Depression can explain 10% of the variability of pain intensity, while kinesiophobia can explain 9% of the variability of disability.Conclusion: There are weak associations that are not clinically relevant between depression and pain severity, and between kinesiophobia and disability severity. However, other psychological factors are not associated with the severity of pain or disability.

Abstract
Fibromyalgia (FM) is a chronic, painful, heterogeneous, and common disorder carrying a substantial socio-economical burden. It lacks effective cures and its aetiology is still unknown. There exists evidence for central and peripheral neurological contribution to the symptoms but grasping the real source of abnormal nervous system sensitization remains an ongoing challenge. There exists an association between an injury/trauma and the onset of the symptoms, but a causal relationship has not been yet sufficiently supported by scientific evidence. I postulate a role for gadolinium-based contrast agents and retention of gadolinium in the body. This conjecture breaks the hypothesis of a direct role for a physical injury/trauma per se in favour of an indirect one by the subsequent diagnostic procedures. It creates a new link between retention of gadolinium in the body and painful conditions as FM and unexplained chronic widespread pain reported after a trauma, surgery, or medical illness. Experimental evidence demonstrates possible retention of gadolinium species in human body, still lacking conclusive answers on their pathological consequences. Notwithstanding, there exist some initial data that report unexplained chronic widespread pain and symptoms of FM in those patients: they are suggestive for pathological consequences associated with gadolinium retention. Besides clear compelling symptoms overlapping, biochemical findings are provided to sustain the hypothesis of a role for gadolinium in the disease process focusing on neurotransmitters, endogenous metal cations, cytokines, and muscle tissue. Experimental findings strongly support the hypothesis of impairment at the cellular, intracellular, and systemic levels in FM. And these data are highly compatible with collateral effects associated with the interference of the gadolinium ion and its pharmaceutical chelates into biochemical pathways in vivo. The hypothesis presented in this article, along with the support of scientific evidence, links FM and unexplained chronic widespread pain reported after a trauma, surgery, or medical illness to retention of gadolinium in the body. If the hypothesis is confirmed, it could improve diagnosis and prevention, while providing a ground for development of new treatments.

Abstract
This article presents the case of a 46-year-old woman with fibromyalgia with an undetected fracture of the coccyx. The heterogeneity of the symptoms of patients suffering from fibromyalgia including chronic widespread pain, vegetative and functional disorders, mental and physical exhaustion as well as sleep disorders can cause accidentally undetected comorbidities, especially if these are rare and predominantly present with pain as the main symptom. In the present case the reason for symptoms was detected only after 14 months of ineffective therapies and diagnostic procedures. The coccygeal pain was eliminated through a coccygectomy as ultima ratio. It should be nevertheless emphasized that patients with fibromyalgia suffer from a central pain-processing disorder. Indications for operative treatment must be very carefully considered. Surgery should only be considered in consultation with the patient and after failed conservative therapy.

Abstract
Exercise-related interventions have been recommended as one of the main components in the management of fibromyalgia syndrome (FMS). Water therapy, which combines water's physical properties and exercise benefits, has proven effective in improving the clinical symptoms of FMS, especially pain, considered the hallmark of this syndrome. However, to our knowledge, the mechanisms underlying water therapy effects on pain are still scarcely explored in the literature. Therefore, this narrative review aimed to present the current perspectives on water therapy and the physiological basis for the mechanisms supporting its use for pain management in patients with FMS. Furthermore, the effects of water therapy on the musculoskeletal, neuromuscular, cardiovascular, respiratory, and neuroendocrine systems and inflammation are also addressed. Taking into account the aspects reviewed herein, water therapy is recommended as a nonpharmacologic therapeutic approach in the management of FMS patients, improving pain, fatigue, and quality of life. Future studies should focus on clarifying whether mechanisms and long-lasting effects are superior to other types of nonpharmacological interventions, as well as the economic and societal impacts that this intervention may present.

Abstract
Objective In 2010, Wolfe et al. demonstrated poor physician use of the 1990 fibromyalgia diagnostic criteria and proposed the 2010 criteria to address physician shortcomings. No follow-up studies have investigated whether physicians are using these criteria. The purpose of this study was to provide seminal data on physician knowledge and use of the fibromyalgia diagnostic criteria. Methods This was an observational study. A questionnaire was distributed to a convenience sample of physicians who diagnose chronic pain conditions. Physician agreement was evaluated with statements testing their knowledge on the fibromyalgia criteria, and then intraclass correlations were calculated to determine the homogeneity of physicians' responses. We also determined whether physician knowledge was impacted by their specialist training and clinical experience. Results Physician responses varied between correct and incorrect agreement on most questions. Physician specialist training was positively correlated with knowledge of the criteria. Physician knowledge overall was not comprehensive and was very poor for the 1990 and 2010 criteria. Fifty-one percent of physicians used a set of criteria in their practice, and 49% used their clinical acumen. Conclusions Physicians do not have adequate and homogenous knowledge of the fibromyalgia diagnostic criteria. Approximately half of physicians did not adhere to the criteria. Poor knowledge and adherence to the criteria may increase diagnosis delays and misdiagnoses. Knowledge translation strategies should be implemented to address this problem.

Abstract
Diagnosis and treatment of fibromyalgia (FM) remains a challenge owing to the lack of reliable biomarkers. Our objective was to develop a rapid biomarker-based method for diagnosing FM by using vibrational spectroscopy to differentiate patients with FM from those with rheumatoid arthritis (RA), osteoarthritis (OA), or systemic lupus erythematosus (SLE) and to identify metabolites associated with these differences. Blood samples were collected from patients with a diagnosis of FM (n = 50), RA (n = 29), OA (n = 19), or SLE (n = 23). Bloodspot samples were prepared, and spectra collected with portable FT-IR and FT-Raman microspectroscopy and subjected to metabolomics analysis by ultra-HPLC (uHPLC), coupled to a photodiode array (PDA) and tandem MS/MS. Unique IR and Raman spectral signatures were identified by pattern recognition analysis and clustered all study participants into classes (FM, RA, and SLE) with no misclassifications (p < 0.05, and interclass distances > 2.5). Furthermore, the spectra correlated (r = 0.95 and 0.83 for IR and Raman, respectively) with FM pain severity measured with fibromyalgia impact questionnaire revised version (FIQR) assessments. Protein backbones and pyridine-carboxylic acids dominated this discrimination and might serve as biomarkers for syndromes such as FM. uHPLC-PDA-MS/MS provided insights into metabolites significantly differing among the disease groups, not only in molecular m/z+ and m/z- values but also in UV-visible chromatograms. We conclude that vibrational spectroscopy may provide a reliable diagnostic test for differentiating FM from other disorders and for establishing serologic biomarkers of FM-associated pain.

Abstract
Background Fibromyalgia is characterized by chronic generalized pain, fatigue, sleep disorders and other symptoms. Physical exercise is recommended as the first choice of non-pharmacological therapy. Thus, the aim of this study is to evaluate the effectiveness and cost-effectiveness of modified Pilates exercises compared to aerobic exercises in the treatment of patients with fibromyalgia. Methods In this randomized controlled trial with blinded assessor, 98 patients who meet the fibromyalgia classification criteria of the American College of Rheumatology 2010, aged between 20 and 75 years, and with pain intensity greater than or equal to 3 points in the Pain Numerical Rating Scale, will be randomly divided into Aerobic Group (aerobic exercises on treadmills or stationary bikes) and Pilates Group (modified Pilates exercises), and treated twice a week for eight weeks on the Center for Excellence in Clinical Research in Physical Therapy at Universidade Cidade de São Paulo, Brazil. The following outcomes will be evaluated by a blinded assessor at baseline, eight weeks, six months, and 12 months after randomization: impact of fibromyalgia assessed by the Fibromyalgia Impact Questionnaire, pain intensity by the Pain Numerical Rating Scale, kinesiophobia by the Tampa Scale of Kinesiophobia, specific disability by the Patient-Specific Functional Scale, functional capacity by the 6-min Walk Test, quality of sleep by the Pittsburgh Sleep Quality Index, and health-related quality of life by EQ-5D-3L and SF-6D questionnaires. Discussion It is expected that the Pilates exercises will be more effective than aerobic exercises in improving clinical outcomes and that this improvement will be maintained over the medium to long term. This study aims to clarify whether the Pilates method can be incorporated into the clinical practice of physical therapists treating patients with fibromyalgia. The study will also provide information on which exercise will be most cost-effective, information that can be used by insurers and public health systems. Trial registration This study was prospectively registered at the Clinical Trials Registry (NCT03050606) in February 2017.

Clin Rheumatol 2018; 38:503-511.

Abstract
Some commonly reported systemic features of joint hypermobility syndrome (JHS)/Ehlers-Danlos syndrome hypermobility type (EDS-HT) are absent from nosologies due to insufficient validity. The primary aim was to examine the hypothesised high prevalence and frequency of orthostatic intolerance, easy bruising, and urinary incontinence in adults with JHS/EDS-HT and secondarily to determine the association between extent of generalised joint hypermobility (GJH) and these systemic features. A cross-sectional cohort study was conducted via online recruitment of medically diagnosed JHS/EDS-HT patients. A survey collected demographic data and clinical history. A subgroup of participants underwent physical testing of GJH using the Beighton score and Lower Limb Assessment Score (LLAS). Descriptive analysis was performed on demographic data and self-reported non-musculoskeletal systemic features. Correlation of GJH scores and systemic features were performed using Spearman's rank correlation. The survey was completed by 116 individuals (95% female; 16-68 years) with 57 (93% female) also participating in the physical assessment. The most prevalent systemic feature was orthostatic intolerance (98%), followed by easy bruising and urinary incontinence (97% and 84% respectively). Of those reporting symptoms of orthostatic intolerance, easy bruising, and urinary incontinence, 58%, 40%, and 18% described them as very highly frequent respectively (frequency > 75%). No significant correlations were found between the extent of systemic features and GJH scores as measured by either the Beighton score or the LLAS. The high prevalence and frequency of the systemic features found in this study, which are omitted in diagnostic classification criteria, suggest that further research on their diagnostic accuracy is warranted.

Abstract
Aim To explore the characteristics of psychiatric morbidity in chronic pain patients who present with or without fibromyalgia. Methods Patients are referred to our chronic pain clinic from primary medical institutions, as we are a secondary medical institution. Although some patients have chronic pain, they have no clear organic disorder such as rheumatoid arthritis to account for the pain. Among the 367 new patients seen during the period from March 2009 to August 2012, 347 patients underwent psychiatric evaluation in face‐to‐face interviews with mental health specialists before a physical examination. Results Of the 347 patients examined, at least one psychiatric diagnosis was made for 94.6%. The average number of DSM‐IV‐TR diagnoses was 1.46 in the 330 chronic pain patients who had at least one psychiatric diagnosis. The breakdown of the number of psychodiagnoses was one in 60.8%, two in 27.1%, three in 4.9%, and more than three in 2.3% chronic pain patients with or without fibromyalgia. In fibromyalgia patients, the highest relative frequencies were found for somatoform disorders (76%), followed by dysthymic disorder (17%) and major depressive disorder (15%). In patients without fibromyalgia, the highest relative frequencies were found for somatoform disorders (64%), followed by major depressive disorder (15%) and dysthymic disorder (14%). Psychiatric disorders were found in 96.9% of fibromyalgia patients, and in 93.5% of chronic pain patients without fibromyalgia in Japan (no significant difference using chi‐square test). Conclusion Results show that chronic pain patients with or without fibromyalgia are extremely likely to be diagnosed with a psychiatric disorder. Psychodiagnoses of fibromyalgia patients and chronic pain patients without fibromyalgia.

Abstract
Patients with fibromyalgia (FM) have often tried many outpatient treatments, and breakthrough pain frequently stops them from performing everyday tasks and participating in society. FM-pain that has become chronic, therefore, affects quality of life. This case study describes the administration of interdisciplinary inpatient pain therapy due to a primary diagnosis of fibromyalgia with integrated complementary medicine. The female patient, who had several concomitant disorders and had been suffering from pain for many years, benefited from the holistic treatment approach in terms of a reduction in pain and an improvement in physical functions and mental health. The ability to have a positive effect on pain symptoms in the longer term is essential. Compliance with the treatments used should also be improved, so that a healthier lifestyle and better pain management can continue after discharge from hospital. These results are supported by other study results and should provide the impetus for major studies to evaluate holistic pain therapies in FM.

Abstract
Fibromyalgia (FM) is a complex chronic disease that affects 3-10% of the general adult population and is principally characterized by widespread pain, and is often associated with disrupted sleep, fatigue, and comorbidities, among other symptoms. There are many gaps in our knowledge of FM, such that, compared with other chronic illnesses including diabetes, rheumatoid arthritis, and asthma, it is far behind in terms of provider understanding and therapeutic approaches. The experience that healthcare professionals (HCPs) historically gained in developing approaches to manage and treat patients with these chronic illnesses may help show how they can address similar problems in patients with FM. In this review, we examine some of the issues around the management and treatment of FM, and discuss how HCPs can implement appropriate strategies for the benefit of patients with FM. These issues include understanding that FM is a legitimate condition, the benefits of prompt diagnosis, use of non-drug and pharmacotherapies, patient and HCP education, watchful waiting, and assessing patients by FM domain so as not to focus exclusively on one symptom to the detriment of others. Developing successful approaches is of particular importance for HCPs in the primary care setting who are in the ideal position to provide long-term care for patients with FM. In this way, FM may be normalized as a chronic illness to the benefit of both patients and HCPs.

Abstract
Fibromyalgia syndrome (FMS) is a chronic, complex, and heterogeneous disorder of still poorly understood etiopathophysiology associated with important musculoskeletal widespread pain, fatigue, non-restorative sleep, and mood disturbances. It is estimated to afflict 2–3% of the worldwide population, with clean prevalence among women. The objective of this paper is to propose a novel treatment for symptomatic remission of FMS, grounded in biochemistry and consisting in the withdrawal from the diet of molecules that can indirectly trigger the symptoms. The hypothesis develops from the evidence that low serotonin levels are involved in FMS. Serotonin is synthesized starting from the essential amino acid tryptophan. The presence of non-absorbed molecules in the gut, primarily fructose, reduces tryptophan absorption. Low tryptophan absorption leads to low serotonin synthesis that triggers FMS symptoms. Moreover not-absorbed sugars could also produce a microbiota deterioration activating a positive feedback loop: the increasing microbiota deterioration reduces the functionality of absorption both of fructose and tryptophan in the gut, entering a vicious circle. The therapeutic idea is to sustain serotonin synthesis allowing the proper tryptophan absorption. The core of the cure treatment is the exclusion from the diet of some carbohydrates and the marked reduction of some others. The main target is the limitation of total dietary fructose as marked as possible. It could be an effective strategy to get the remission of symptoms acting on the impaired biochemical pathways. The straying from the treatment is expected to cause the reappear of the symptoms.

Abstract
[Purpose] An easy-to-use, psychometrically validated screening tool for fibromyalgia is
needed. This study aims to evaluate the reliability and validity of the Turkish version of
the Fibromyalgia Rapid Screening Tool by correlating it with 2013 American College of
Rheumatology alternative diagnostic criteria and the Hospital Anxiety and Depression
Scale. [Subjects and Methods] Subjects were 269 Physical Medicine and Rehabilitation
clinic outpatients. Patients completed a questionnaire including the Fibromyalgia Rapid
Screening Tool (twice), 2013 American College of Rheumatology alternative diagnostic
criteria, and the Hospital Anxiety and Depression Scale. Scale reliability was examined by
test-retest. The 2013 American College of Rheumatology alternative diagnostic criteria was
used for comparison to determine criterion validity. The sensitivity, specificity, and
positive and negative likelihood ratios were calculated according to 2013 American College
of Rheumatology alternative diagnostic criteria. Logistic regression analysis was
conducted to find the confounding effect of the Hospital Anxiety and Depression Scale on
Fibromyalgia Rapid Screening Tool to distinguish patients with fibromyalgia syndrome.
[Results] The Fibromyalgia Rapid Screening Tool was similar to the 2013 American College
of Rheumatology alternative diagnostic criteria in defining patients with fibromyalgia
syndrome. Fibromyalgia Rapid Screening Tool score was correlated with 2013 American
College of Rheumatology alternative diagnostic criteria subscores. Each point increase in
Fibromyalgia Rapid Screening Tool global score meant 10 times greater odds of experiencing
fibromyalgia syndrome. [Conclusion] The Turkish version of the Fibromyalgia Rapid
Screening Tool is reliable for identifying patients with fibromyalgia.

Abstract
Little is known regarding fibromyalgia syndrome (FMS) care among Operation Iraqi Freedom/Operation Enduring Freedom/Operation New Dawn (OIF/OEF/OND) Veterans. Current recommendations include interdisciplinary, team-based combined care approaches and limited opioid use. In this study of OIF/OEF/OND Veterans who accessed Veterans Health Administration services between 2002 and 2012, we hypothesized that combined care (defined as at least 4 primary care visits/yr with visits to mental health and/or rheumatology) versus <4 primary care visits/yr only would be associated with lower risk of at least 2 opioid prescriptions 12 mo following an FMS diagnosis. Using generalized linear models with a log-link, the Poisson family, and robust standard errors, we estimated risk ratios (RRs) and 95% confidence intervals (CIs). We found that 1% of Veterans had at least 2 FMS diagnoses (International Classification of Diseases-9th Revision-Clinical Modification code 729.1) or at least 1 FMS diagnosis by rheumatology. Veterans with (vs without) FMS were more likely to be female, older, Hispanic, and never/currently married. Combined primary, mental health, and rheumatology care was associated with at least 2 opioid prescriptions (RR [95% CI] for males 2.2 [1.1-4.4] and females 2.8 [0.4-18.6]). Also, combined care was associated with at least 2 nonopioid pain-related prescriptions, a practice supported by evidence-based clinical practice guidelines. In tandem, these results provide mixed evidence of benefit of combined care for FMS. Future studies of healthcare encounter characteristics, care coordination, and benefits for Veterans with FMS are needed.

Abstract
Fibromyalgia is a disorder that is part of a spectrum of syndromes that lack precise classification. It is often considered as part of the global overview of functional somatic syndromes that are otherwise medically unexplained or part of a somatization disorder. Patients with fibromyalgia share symptoms with other functional somatic problems, including issues of myalgias, arthralgias, fatigue and sleep disturbances. Indeed, there is often diagnostic and classification overlap for the case definitions of a variety of somatization disorders. Fibromyalgia, however, is a critically important syndrome for physicians and scientists to be aware of. Patients should be taken very seriously and provided optimal care. Although inflammatory, infectious, and autoimmune disorders have all been ascribed to be etiological events in the development of fibromyalgia, there is very little data to support such a thesis. Many of these disorders are associated with depression and anxiety and may even be part of what has been sometimes called affected spectrum disorders. There is no evidence that physical trauma, i.e., automobile accidents, is associated with the development or exacerbation of fibromyalgia. Treatment should be placed on education, patient support, physical therapy, nutrition, and exercise, including the use of drugs that are approved for the treatment of fibromyalgia. Treatment should not include opiates and patients should not become poly pharmacies in which the treatment itself can lead to significant morbidities. Patients with fibromyalgia are living and not dying of this disorder and positive outlooks and family support are key elements in the management of patients.

Cost-Saving Early Diagnosis of Functional Pain in Nonmalignant Pain: A Noninferiority Study of Diagnostic Accuracy. PAIN RESEARCH AND TREATMENT 2016; 2016:5964250.

Abstract
Objectives. We compared two index screening tests for early diagnosis of functional pain: pressure pain measurement by electronic diagnostic equipment, which is accurate but too specialized for primary health care, versus peg testing, which is cost-saving and more easily manageable but of unknown sensitivity and specificity. Early distinction of functional (altered pain perception; nervous sensitization) from neuropathic or nociceptive pain improves pain management. Methods. Clinicians blinded for the index screening tests assessed the reference standard of this noninferiority diagnostic accuracy study, namely, comprehensive medical history taking with all previous findings and treatment outcomes. All consenting patients referred to a university hospital for nonmalignant musculoskeletal pain participated. The main analysis compared the receiver operating characteristic (ROC) curves of both index screening tests. Results. The area under the ROC curve for peg testing was not inferior to that of electronic equipment: it was at least 95% as large for finger measures (two-sided p = 0.038) and at least equally as large for ear measures (two-sided p = 0.003). Conclusions. Routine diagnostic testing by peg, which is accessible for general practitioners, is at least as accurate as specialized equipment. This may shorten time-to-treatment in general practices, thereby improving the prognosis and quality of life.

Abstract
AIMS Fibromyalgia (FM), a chronic disorder defined by widespread pain, often accompanied by fatigue and sleep disturbance, affects up to one in 20 patients in primary care. Although most patients with FM are managed in primary care, diagnosis and treatment continue to present a challenge, and patients are often referred to specialists. Furthermore, the lack of a clear patient pathway often results in patients being passed from specialist to specialist, exhaustive investigations, prescription of multiple drugs to treat different symptoms, delays in diagnosis, increased disability and increased healthcare resource utilisation. We will discuss the current and evolving understanding of FM, and recommend improvements in the management and treatment of FM, highlighting the role of the primary care physician, and the place of the medical home in FM management. METHODS We reviewed the epidemiology, pathophysiology and management of FM by searching PubMed and references from relevant articles, and selected articles on the basis of quality, relevance to the illness and importance in illustrating current management pathways and the potential for future improvements. RESULTS The implementation of a framework for chronic pain management in primary care would limit unnecessary, time-consuming, and costly tests, reduce diagnostic delay and improve patient outcomes. DISCUSSION The patient-centred medical home (PCMH), a management framework that has been successfully implemented in other chronic diseases, might improve the care of patients with FM in primary care, by bringing together a team of professionals with a range of skills and training. CONCLUSION Although there remain several barriers to overcome, implementation of a PCMH would allow patients with FM, like those with other chronic conditions, to be successfully managed in the primary care setting.

Abstract
The purpose of this study is to understand the course of costs over a 2-year period in a cohort of recently diagnosed fibromyalgia (FM) patients receiving different treatment strategies. Following the diagnosis, patients were randomly assigned to a multidisciplinary programme (MD), aerobic exercise (AE) or usual care (UC) without being aware of alternative interventions. Time between diagnosis and start of treatment varied between patients. Resource utilisation, health care costs and costs for patients and families were collected through cost diaries. Mixed linear model analyses (MLM) examined the course of costs over time. Linear regression was used to explore predictors of health care costs in the post-intervention period. Two hundred three participants, 90 % women, mean (SD) age 41.7 (9.8) years, were included in the cohort. Intervention costs per patient varied from €864 to 1392 for MD and were €121 for AE. Health care costs (excluding intervention costs) decreased after diagnosis, but before the intervention in each group, and increased again afterwards to the level close to the diagnostic phase. In contrast, patient and family costs slightly increased over time in all groups without initial decrease immediately after diagnosis. Annualised health care costs post-intervention varied between €1872 and 2310 per patient and were predicted by worse functioning and high health care costs at diagnosis. In patients with FM, health care costs decreased following the diagnosis by a rheumatologist. Offering patients a specific intervention after diagnosis incurred substantial costs while having only marginal effects on costs.

Abstract
This review has focused on important but less visible aspects of fibromyalgia (FM) with respect to the high impact of this disorder on patients and societies. FM is a common but challengeable illness. It is characterized by chronic widespread pain, which can be accompanied by other symptoms including fatigue, sleep disturbances, cognitive dysfunction, anxiety and depressive episodes. While our understanding of this debilitating disorder is limited, diagnosis and treatment of this condition is very difficult, even in the hands of experts. Due to the nature of disease, where patients experience invalidation by medical services, their families and societies regarding the recognition and management of disease, direct, indirect and immeasurable costs are considerable. These clinical and economic costs are comparable with other common diseases, such as diabetes, hypertension and osteoarthritis, but the latter usually receives much more attention from healthcare and non-healthcare resources. Present alarming data shows the grave and "iceberg-like" burden of FM despite the benign appearance of this disorder and highlights the urgent need both for greater awareness of the disease among medical services and societies, as well as for more research focused on easily used diagnostic methods and target specific treatment.

BACKGROUND Chronic multisymptom illness (CMI) may be more prevalent among female Operation Enduring Freedom/Operation Iraqi Freedom/Operation New Dawn (OEF/OIF/OND) deployed Veterans due to deployment-related experiences. OBJECTIVES To investigate CMI-related diagnoses among female OEF/OIF/OND Veterans. RESEARCH DESIGN We estimated the prevalence of the International Classification of Disease-9th edition-Clinical Modification coded CMI-related diagnoses of chronic fatigue syndrome, fibromyalgia (FM), and irritable bowel syndrome (IBS) among female OEF/OIF/OND Veterans with Veterans Health Administration (VHA) visits, FY2002-2012 (n=78,435). We described the characteristics of female Veterans with and without CMI-related diagnoses and VHA settings of first CMI-related diagnoses. RESULTS The prevalence of CMI-related diagnoses among female OEF/OIF/OND Veterans was 6397 (8.2%), over twice as high as the prevalence 95,424 (3.9%) among the totality of female Veterans currently accessing VHA (P<0.01). There were statistically significant differences in age, education, marital status, military component, service branch, and proportions of those with depression and/or post-traumatic stress disorder diagnoses across females with and without CMI-related diagnoses. Diagnoses were mainly from primary care, women's health, and physical medicine and rehabilitation clinics. CONCLUSIONS CMI-related diagnoses were more prevalent among female OEF/OIF/OND Veterans compared with all female Veterans who currently access VHA. Future studies of the role of mental health diagnoses as confounders or mediators of the association of OEF/OIF/OND deployment and CMI are warranted. These and other factors associated with CMI may provide a basis for enhanced screening to facilitate recognition of these conditions. Further work should evaluate models of care and healthcare utilization related to CMI in female Veterans.

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
Fibromyalgia (FM) primarily affects women, and it is increasingly recognized by health care providers as more patients seek assistance for their chronic pain conditions. FM patients suffer from reduced quality of life, daily functioning and productivity. A single FM patient can cost society tens of thousands of dollars each year, with the overall expense increasing alongside disease severity. Indirect costs account for the majority of total expenditures and involve losses in productivity, reduced work hours, absenteeism, disability, unemployment, early retirement, informal care and other out-of-pocket costs. Health care utilization increases in concert with the severity of illness. Moreover, FM patients often have several comorbid illnesses (e.g. depression, anxiety and sleep disturbances), resulting in extreme escalation of overall health care expenditures. Medications with the best efficacy in the treatment of FM include the tricyclic antidepressants amitriptyline and nortriptyline, cyclobenzaprine (a skeletal muscle relaxant), tramadol, duloxetine, milnacipran, pregabalin and gabapentin. Corticosteroids, nonsteroidal anti-inflammatory drugs, benzodiazepines and opioid analgesics, with the exception of tramadol, are not considered efficacious. Medication selection should be individualized and influenced by the severity of illness and the presence of comorbidities and functional disabilities.

Abstract
INTRODUCTION Juvenile fibromyalgia syndrome (JFS) is a medically unexplained illness that can cause persistent, diffuse pain in a child or adolescent. This pain can lead to anxiety or depression and absence from school or work, and it can adversely affect a child's quality of life and family relationships. Prompt recognition of JFS may decrease problems for pediatric patients with chronic pain, but pediatric primary care providers' lack of familiarity with JFS can cause a delay in diagnosis. METHOD A project using a developed screening tool, the SORE Scoresheet, was implemented in the pediatric clinic at Kaiser Permanente Fontana from September 2011 to January 2012. Pediatric providers were educated about the tool before the project began. RESULTS Twenty-two patients with JFS were referred with use of the SORE Scoresheet. Symptoms of JFS matched at a rate of 93% between the providers and the rheumatologist, and a reduction in the number of weeks to referral and the number of visits before referral was found compared with a sample of patients with JFS from 2010. CONCLUSION Pediatric provider education and development of a screening tool assists with the recognition of JFS.

Abstract
BACKGROUND Recent neurophysiological evidence attests to the validity of fibromyalgia (FM), a chronic pain condition that affects >2% of the population. OBJECTIVES To present the evidence-based guidelines for the diagnosis, management and patient trajectory of individuals with FM. METHODS A needs assessment following consultation with diverse health care professionals identified questions pertinent to various aspects of FM. A literature search identified the evidence available to address these questions; evidence was graded according to the standards of the Oxford Centre for Evidence-Based Medicine. Drafted recommendations were appraised by an advisory panel to reflect meaningful clinical practice. RESULTS The present recommendations incorporate the new clinical concepts of FM as a clinical construct without any defining physical abnormality or biological marker, characterized by fluctuating, diffuse body pain and the frequent symptoms of sleep disturbance, fatigue, mood and cognitive changes. In the absence of a defining cause or cure, treatment objectives should be patient-tailored and symptom-based, aimed at reducing global complaints and enhancing function. Healthy lifestyle practices with active patient participation in health care forms the cornerstone of care. Multimodal management may include nonpharmacological and pharmacological strategies, although it must be acknowledged that pharmacological treatments provide only modest benefit. Maintenance of function and retention in the workforce is encouraged. CONCLUSIONS The new Canadian guidelines for the treatment of FM should provide health professionals with confidence in the complete care of these patients and improve clinical outcomes.

Abstract
Abstract
Fibromyalgia is a common chronic syndrome defined by core symptoms of widespread pain, fatigue, and sleep disturbance. Other common symptoms include cognitive difficulty, headache, paresthesia, and morning stiffness. Fibromyalgia is increasingly understood as 1 of several disorders that are referred to as central sensitivity syndromes; these disorders share underlying causes and clinical features. Tender points are often detected in patients with fibromyalgia and were formerly required for diagnosis. Newly proposed criteria, however, rely on patients' reports of widespread pain and other somatic symptoms to establish the diagnosis of fibromyalgia. The management of fibromyalgia requires a multidimensional approach including patient education, cognitive behavioral therapy, exercise, and pharmacologic therapy. The present review provides an update on these various aspects of treating a patient with fibromyalgia.

Abstract
OBJECTIVE To summarize the development of evidence-based guidelines for the clinical care of persons with fibromyalgia (FM), taking into account advances in understanding of the pathogenesis of FM, new diagnostic criteria, and new treatment options. METHODS Recommendations for diagnosis, treatment, and patient followup were drafted according to the classification system of the Oxford Centre for Evidence-Based Medicine, and following review were endorsed by the Canadian Rheumatology Association and the Canadian Pain Society. RESULTS FM is a polysymptomatic syndrome presenting a spectrum of severity, with a pivotal symptom of body pain. FM is a positive clinical diagnosis, not a diagnosis of exclusion, and not requiring specialist confirmation. There are no confirmatory laboratory tests, although some investigation may be indicated to exclude other conditions. Ideal care is in the primary care setting, incorporating nonpharmacologic and pharmacologic strategies in a multimodal approach with active patient participation. The treatment objective should be reduction of symptoms, but also improved function using a patient-tailored treatment approach that is symptom-based. Self-management strategies combining good lifestyle habits and fostering a strong locus of control are imperative. Medications afford only modest relief, with doses often lower than suggested, and drug combinations used according to clinical judgment. There is a need for continued reassessment of the risk-benefit ratio for any drug treatment. Outcome should be aimed toward functioning within a normal life pattern and any culture of disablement should be discouraged. CONCLUSION These guidelines should provide the health community with reassurance for the global care of patients with FM with the aim of improving patient outcome by reducing symptoms and maintaining function.

Abstract
Objective.To determine the specificity and sensitivity of the Modified 2010 American College of Rheumatology (ACR) Diagnostic Criteria for Fibromyalgia (given as a self-administered questionnaire) in clinical practice.Methods.A cohort of patients with widespread pain, referred by primary care physicians to rheumatologists, completed the questionnaire for the Modified ACR 2010 criteria. Prior to completion of the questionnaire, patients were diagnosed by at least 1 rheumatologist as either having fibromyalgia (FM) or not having FM, using the rheumatologist’s clinical assessment as the gold standard for diagnosis of FM. The Modified ACR 2010 criteria were then applied to determine whether a diagnosis of FM was satisfied by the criteria. Sensitivity and specificity were determined, using the rheumatologist’s clinical assessment as the gold standard. A score ≥ 12 on the Modified ACR 2010 criteria questionnaire was also tested as the criterion to satisfy a diagnosis of FM, and subsequently to determine sensitivity and specificity. We examined the effect of using a cutoff score ≥ 13, as previous research indicated that this may be a more useful cutoff value.Results.A total of 451 subjects completed the questionnaire: 174 with an a priori diagnosis of FM by a rheumatologist and 277 with widespread pain who did not have an a priori clinical diagnosis of FM by a rheumatologist. The Modified ACR 2010 criteria were satisfied by 90.2% of patients with an a priori diagnosis of FM, and by 10.5% of subjects who had widespread pain, but were not diagnosed with FM when previously assessed by a rheumatologist. Thus, sensitivity and specificity are 90.2% and 89.5%, respectively, using the Modified ACR 2010 criteria. A score ≥ 12 on the Modified ACR 2010 criteria was observed in 97.4% of patients with an a priori diagnosis of FM, and 14.8% of subjects who had widespread pain, but were not diagnosed with FM when previously assessed by a rheumatologist. Thus, the sensitivity and specificity are 97.4% and 85.2%, respectively, using a cutoff score ≥ 12. Using a score of ≥ 13, however, the sensitivity was 93.1% and the specificity was 91.7%.Conclusion.The Modified ACR 2010 criteria questionnaire can be used in primary care as a tool to assist physicians in the diagnosis of FM with high specificity and sensitivity. Calculating the total score on a Modified ACR 2010 criteria questionnaire, and setting the value of ≥ 13 as the cutoff for a diagnosis of FM appears to be the most effective approach. The Modified ACR 2010 criteria may reduce the need for rheumatology referral simply for the diagnosis of FM.

Abstract
The aim of this study was to investigate the ability of a rapid biomarker-based method for diagnosis of fibromyalgia syndrome (FM) using mid-infrared microspectroscopy (IRMS) to differentiate patients with FM from those with osteoarthritis (OA) and rheumatoid arthritis (RA), and to identify molecular species associated with the spectral patterns. Under IRB approval, blood samples were collected from patients diagnosed with FM (n = 14), RA (n = 15), or OA (n = 12). Samples were prepared, placed onto a highly reflective slide, and spectra were collected using IRMS. Spectra were analyzed using multivariate statistical modeling to differentiate groups. Aliquots of samples also were subjected to metabolomic analysis. IRMS separated subjects into classes based on spectral information with no misclassifications among FM and RA or OA patients. Interclass distances of 15.4 (FM vs. RA), 14.7 (FM vs. OA) and 2.5 (RA vs. OA) among subjects, demonstrating the ability of IRMS to achieve reliable resolution of unique spectral patterns specific to FM. Metabolomic analysis revealed that RA and OA groups were metabolically similar, whereas biochemical differences were identified in the FM that were quite distinctive from those found in the other two groups. Both IRMS and metabolomic analysis identified changes in tryptophan catabolism pathway that differentiated patients with FM from those with RA or OA.
