Hypereosinophilia and eosinophilic arterial aneurysm: not only eosinophilic granulomatosis with polyangiitis
Steroid-sparing agents in polymyalgia rheumatica: how will they fit into the treatment paradigm?
Introduction: Polymyalgia rheumatica is a common inflammatory rheumatic disease in subjects aged 50 years or older and classically presents with shoulder and/or pelvic girdle pain and prolonged morning stiffness. Glucocorticoids represent the standard of treatment; glucocorticoid therapy is usually required for 1–2 years and often results in significant glucocorticoid-related side effects, especially in the elderly. Areas covered: In this review, we aimed to provide a comprehensive overview of the management of polymyalgia rheumatica, with a particular focus on adjunctive therapies to the standard glucocorticoid treatment. Expert opinion: Given the high frequency of disease relapses (one-third of patients) and the adverse events related to prolonged glucocorticoid use, the need for glucocorticoid-sparing agents remains an important issue in the management of polymyalgia rheumatica. In selected patients, who are at risk for glucocorticoid-related side effects or in those with glucocorticoid-refractory disease, the addition of a glucocorticoid-sparing agent, either a synthetic or biologic disease-modifying anti-rheumatic drug, may represent a reasonable and effective therapeutic approach
Comparing treatment options for large vessel vasculitis
Introduction: Giant cell arteritis (GCA) and Takayasu arteritis (TAK) are the major forms of large vessel vasculitis (LVV). Glucocorticoids represent the cornerstone of LVV treatment, however, relapses and recurrences frequently occur when they are tapered or stopped, determining a prolonged exposure to glucocorticoids and a subsequent increased risk of glucocorticoid-related side effects. Therefore, conventional and biologic immunosuppressive drugs have been proposed to obtain a glucocorticoid-sparing effect. Areas covered: We searched PubMed® using the keywords ‘giant cell arteritis/drug therapy’ and ‘Takayasu Arteritis/drug therapy’ OR ‘Takayasu Arteritis/surgery’ This review focuses on the management of LVV, based on the current evidence while highlighting the differences in terms of therapeutic management of TAK and GCA. Expert opinion: Conventional disease modifying anti-rheumatic drugs, such as methotrexate or azathioprine, are recommended in association to glucocorticoids for selected GCA and all TAK patients. Two randomized placebo-controlled trials recently demonstrated the efficacy of tocilizumab in reducing relapses and cumulative prednisone dosage in GCA patients with newly diagnosed or relapsing disease. Observational evidence and two small randomized controlled trials support the use of TNF-alpha inhibitors and tocilizumab as glucocorticoid-sparing agents in relapsing TAK, albeit high-quality evidence regarding the management of TAK is still lacking
The role of sacro-iliac joint magnetic resonance imaging in the diagnosis of axial spondyloarthritis: focus on differential diagnosis in women
Objective. To review the role of sacro-iliac magnetic resonance imaging (MRI) in the diagnosis of axial spondy-loarthritis (AxSpA), with a focus on gender differences. Methods. The experience of the authors and the results of an informal literature review are reported. Results. Inflammatory changes of the sacro-iliac joint are the hallmark of AxSpA. Early, non-radiographic sac-roiliitis may be diagnosed with MRI through the assessment of bone marrow edema (BMO) as well as concomitant structural damage. The MRI protocol should include three necessary sequences, i.e., fat-saturated T2-weighted sequences on two orthogonal planes, T1-weighted semi-coronal sequence, and fat-suppressed T1-weighted semi-coronal sequence. Inflammatory changes comprise required signs (BMO and/or osteitis) and additional signs, including synovitis (better defined as joint space enhancement), enthesitis, and capsulitis. Structural changes consist of erosions, sclerosis, fat metaplasia, and ankylosis. Due to mechanical axial strain, inflammatory changes in the sacro-iliac joint can be found in healthy individuals, runners, and patients with nonspecific low back pain. The prevalence of BMO is higher in women during pregnancy and postpartum, even 12 months after childbirth, but the extent and distribution of MRI findings may help in the differential diagnosis. Other challenges in the MRI diagnosis of sacroiliitis are subchondral T2 hyperintensity during developmental age, periarticular sclerosis in healthy subjects, or osteitis condensans ilii, and several pathological conditions that may mimic AxSpA, some of which are more frequently found in women. Conclusions. The described diagnostic challenges impose a multidisciplinary approach combining imaging findings with clinical and laboratory data
Going Beyond Counting First Authors in Author Co-citation Analysis
The present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed

Variations on the Author
“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
The Role of PET in the Diagnosis and Disease Activity Assessment in Large Vessel Vasculitis
The role of 18F-fluorodeoxyglucose (FDG) positron emission tomography (18F-FDG PET) in the diagnosis of large vessel vasculitis (LVV) is well established. It permits us to assess the extent and the grade of vascular involvement and to rule out the other causes in clinical scenarios characterized by less specific symptoms. The advantages of 18F-FDG PET are far less clear in monitoring disease activity over time. Studies looking for the role of 18F-FDG PET as a potential biomarker had conflicting results and whether and when to repeat it during follow-up is based on clinical experience. A comprehensive assessment, including clinical, laboratory and morphological imaging is still required to monitor patients with large-vessel vasculitis over time. The aim of this review is to present more recent data about the utility of 18 F-FDG PET in the diagnosis and follow-up of LVV
