ABSTRACT
Immunoglobulin G4-related disease is a systemic immune-mediated disease with insidious evolution characterized by fibroinflammatory lesions over virtually any organ system. Despite the remarkable progression of knowledge, its etiology remains undefined. Due to its relapse-remitting pattern, it could accumulate irreversible damage, increasing comorbidities and mortality. This paper emphasizes key concepts for diagnosing and treating patients with this condition.

Despite their rarity, Lyme disease and Whipple's disease are of significant importance in rheumatology, as both can manifest as chronic arthritis, presenting challenges in the differential diagnosis of inflammatory arthropathies. In Lyme disease, arthritis typically emerges as a late manifestation, usually occurring six months after the onset of erythema migrans. The predominant presentation involves mono- or oligoarthritis of large joints, with a chronic or remitting-recurrent course. Even with appropriate antimicrobial treatment, arthritis may persist due to inadequate immunological control triggered by the disease. In contrast, Whipple's disease may present with a migratory and intermittent seronegative poly- or oligoarthritis of large joints, preceding classic gastrointestinal symptoms by several years. Both disorders, particularly Whipple's disease, can be misdiagnosed as more common autoimmune rheumatic conditions such as rheumatoid arthritis and spondyloarthritis. Epidemiology is crucial in suspecting and diagnosing Lyme disease, as the condition is transmitted by ticks prevalent in specific areas of the United States, Europe, and Asia. On the contrary, the causative agent of Whipple's disease is widespread in the environment, yet invasive disease is rare and likely dependent on host genetic factors. In addition to erythema migrans in Lyme disease and gastrointestinal manifestations in Whipple's disease, neurological and cardiac involvement can further complicate the course of both. This article offers a comprehensive review of the epidemiological, pathophysiological, clinical, and therapeutic aspects of both diseases.

Gaucher and Fabry diseases are lysosomal storage disorders in which deficient enzyme activity leads to pathological accumulation of sphingolipids. These diseases have a broad phenotypic presentation. Musculoskeletal symptoms and pain complaints are frequently reported by patients. Thus, rheumatologists can be contacted by these patients, contributing to the correct diagnosis, earlier indication of appropriate treatment and improvement of their prognosis. This review describes important concepts about Gaucher and Fabry diseases that rheumatologists should understand to improve patients' quality of life and change the natural history of these diseases.

Primary Sjögren's syndrome (pSS) is a systemic autoimmune disease that affects exocrine glands, mainly the salivary and lacrimal glands, leading to the development of sicca symptoms. Patients with pSS may also present with extraglandular manifestations, including lung involvement, estimated to occur in 9-24% of cases. Shrinking lung syndrome (SLS) is an uncommon respiratory complication primarily associated with systemic lupus erythematosus, with a prevalence of approximately 1% in these patients. It typically manifests as dyspnea, pleuritic chest pain, lung volume reduction, and a restrictive pattern on respiratory function tests. Cases reporting SLS with other connective tissue diseases, including pSS, are even rarer. Herein, we describe a case of a 57-year-old woman with a 10-year history of pSS who presented with dyspnea and pleuritic chest pain. After evaluation, the patient was diagnosed with SLS based on clinical, radiologic, laboratorial, and electrophysiologic characteristics. In addition, we identified and analyzed previously published cases of SLS in pSS. Treatment includes corticosteroids, immunosuppressants, and respiratory muscle training. This study highlights the importance of considering SLS in the differential diagnosis of patients with pSS and respiratory symptoms.
ABSTRACT
Demyelinating and inflammatory myelopathies represent a group of diseases with characteristic patterns in neuroimaging and several differential diagnoses. The main imaging patterns of demyelinating myelopathies (multiple sclerosis, neuromyelitis optica spectrum disorder, acute disseminated encephalomyelitis, and myelin oligodendrocyte glycoprotein antibody-related disorder) and inflammatory myelopathies (systemic lupus erythematosus-myelitis, sarcoidosis-myelitis, Sjögren-myelitis, and Behçet's-myelitis) will be discussed in this article, highlighting key points to the differential diagnosis.

Hypertrophic pachymeningitis (HP) is a rare and chronic inflammatory disorder presenting as localized or diffuse thickening of the dura mater. It can be idiopathic or an unusual manifestation of immune-mediated, infectious, and neoplastic conditions. Although some cases may remain asymptomatic, HP can lead to progressive headaches, cranial nerve palsies, hydrocephalus, and other neurological complications, which makes its recognition a fundamental step for prompt treatment. Regarding the diagnosis workup, enhanced MRI is the most useful imaging method to evaluate dural thickening. This article addresses the MR imaging patterns of immune-mediated HP, including immunoglobulin G4-related disease, neurosarcoidosis, granulomatosis with polyangiitis, rheumatoid pachymeningitis, and idiopathic HP. The main infectious and neoplastic mimicking entities are also discussed with reference to conventional and advanced MR sequences.

OBJECTIVES: To compare pain intensity among individuals with idiopathic inflammatory myopathies (IIMs), other systemic autoimmune rheumatic diseases (AIRDs), and without rheumatic disease (wAIDs). METHODS: Data were collected from the COVID-19 Vaccination in Autoimmune Diseases (COVAD) study, an international cross-sectional online survey, from December 2020 to August 2021. Pain experienced in the preceding week was assessed using numeral rating scale (NRS). We performed a negative binomial regression analysis to assess pain in IIMs subtypes and whether demographics, disease activity, general health status, and physical function had an impact on pain scores. RESULTS: Of 6988 participants included, 15.1% had IIMs, 27.9% had other AIRDs, and 57.0% were wAIDs. The median pain NRS in patients with IIMs, other AIRDs, and wAIDs were 2.0 (interquartile range [IQR] = 1.0-5.0), 3.0 (IQR = 1.0-6.0), and 1.0 (IQR = 0-2.0), respectively (P < 0.001). Regression analysis adjusted for gender, age, and ethnicity revealed that overlap myositis and antisynthetase syndrome had the highest pain (NRS = 4.0, 95% CI = 3.5-4.5, and NRS = 3.6, 95% CI = 3.1-4.1, respectively). An additional association between pain and poor functional status was observed in all groups. Female gender was associated with higher pain scores in almost all scenarios. Increasing age was associated with higher pain NRS scores in some scenarios of disease activity, and Asian and Hispanic ethnicities had reduced pain scores in some functional status scenarios. CONCLUSION: Patients with IIMs reported higher pain levels than wAIDs, but less than patients with other AIRDs. Pain is a disabling manifestation of IIMs and is associated with a poor functional status.

Fibromyalgia is a chronic pain syndrome with a complex multifactorial etiopathogenesis that more frequently affects women. Although widespread pain is the dominant feature, fibromyalgia incorporates a wide variety of symptoms, such as fatigue, unrefreshed sleep, and cognitive and mood disorders. Central sensitization to pain is a key element in the pathophysiology of this syndrome. Due to its prevalence and repercussions on quality of life and work productivity, fibromyalgia is a common condition in occupational medicine outpatient clinics. Thus, physicians must be attentive to its symptoms to facilitate diagnosis and management. This article will address basic topics about fibromyalgia, including: epidemiology, predisposing factors, pathophysiological considerations, clinical manifestations, classification criteria, differential diagnosis, basic principles of treatment, and the contribution of occupational physicians.
fibromialgia é uma síndrome dolorosa crônica, de etiopatogenia multifatorial complexa, que acomete com maior frequência mulheres. Embora a dor difusa seja o quadro dominante, a fibromialgia incorpora uma ampla variedade de sintomas, como fadiga, sono não reparador, queixas cognitivas e distúrbios de humor. A sensibilização central à dor é um elemento-chave no entendimento da fisiopatologia dessa síndrome. Por ser prevalente e ter reflexos na qualidade de vida e na produtividade no trabalho, a fibromialgia é uma condição recorrente em ambulatórios de saúde ocupacional. Nesse sentido, é importante que o médico do trabalho esteja atento aos sintomas da síndrome para que possa contribuir com seu diagnóstico e manejo. Neste artigo, serão abordados tópicos fundamentais para a compreensão da fibromialgia, incluindo epidemiologia, fatores predisponentes, considerações sobre a fisiopatologia, manifestações clínicas, critérios classificatórios, diagnósticos diferenciais, princípios básicos do tratamento e contribuições do médico do trabalho.
ABSTRACT
In this paper, we sought to determine the prevalence of arthritis mutilans in a single cohort of Brazilian psoriatic arthritis patients followed at a tertiary university reference center. Our study demonstrated a high prevalence of arthritis mutilans associated to comorbidities and biologic therapy. In addition, our data suggest that axial involvement may be an intriguing aspect of psoriatic arthritis mutilans and that rheumatologists should be aware of axial disease, even if the phenotype is marked by peripheral joint severity.

OBJECTIVE: To review articles that assessed work-related outcomes such as workability, work productivity, presenteeism, absenteeism, sick leave, return to work, and employment status of Brazilian patients with rheumatoid arthritis, systemic lupus erythematosus, systemic sclerosis, Sjögren's syndrome, and systemic autoimmune myopathies. METHODS: This study was conducted in Medline databases (PubMed), SciELO, and Lilacs through a combination of descriptors of interest. Studies published until December 2020 were considered in the search strategy. RESULTS: Eight out of 90 articles met the eligibility criteria and were included in this review. The studies are highly heterogeneous. Most of them are cross-sectional, and all of them address rheumatoid arthritis or systemic lupus erythematosus. A common denominator among these studies is the high proportion of patients outside the labor market. CONCLUSIONS: In general, the studies show unfavorable labor outcomes and impaired participation in the Brazilian workforce among the samples of patients assessed. There is a need to better understand several topics about Brazilian patients with systemic autoimmune diseases and their work context, as well as to conduct studies focusing on rarer diseases and on the themes of return and reintegration to work.

ABSTRACT
OBJECTIVE: To review articles that evaluated the prevalence of Raynaud's phenomenon of occupational origin. METHODS: The search for articles was carried out in the Medline (via PubMed), Embase, Web of Science, Scientific Electronic Library Online (SciELO), and Latin America and Caribbean Health Sciences Literature (Lilacs) databases. RESULTS: 64 articles were obtained from the electronic search; 18 articles met the eligibility criteria. All studies discussed the exposure to vibrations in the upper limbs. In 6 of them, the thermal issue was directly or indirectly addressed. No studies have addressed exposure to vinyl chloride. CONCLUSIO: In general, a higher prevalence of Raynaud's phenomenon was found among vibratory tool operators compared to non-exposed workers, with an increase in the number of cases the higher the level of vibration and the time of exposure. Cold is a triggering and aggravating factor of the Raynaud phenomenon and seems to play an important role in the emergence of vascular manifestations of the hand-arm vibration syndrome.

RESUMO OBJETIVO Realizar um estudo de revisão dos artigos que avaliaram a prevalência do fenômeno de Raynaud de origem ocupacional. MÉTODOS A busca pelos artigos foi realizada nas bases de dados Medline (via PubMed), Embase, Web of Science, Scientific Eletronic Library Online (SciELO) e Literatura Latino-Americana e do Caribe em Ciências da Saúde (Lilacs). RESULTADOS Sessenta e quatro artigos foram obtidos a partir da busca eletrônica, dos quais 18 cumpriram os critérios de elegibilidade. Todos os estudos discutiram sobre a exposição a vibrações localizadas em membros superiores. Em seis deles, a questão térmica foi direta ou indiretamente abordada. Nenhum estudo abordou a exposição ao cloreto de vinila. CONCLUSÃO De maneira geral, constatou-se maior prevalência do fenômeno de Raynaud entre operadores de ferramentas vibratórias em comparação aos não expostos, com aumento do número de casos quanto maior o nível de vibração e tempo de exposição. O frio é fator desencadeante e agravante do fenômeno de Raynaud e parece exercer papel importante para o surgimento das manifestações vasculares da síndrome de vibração de mãos e braços.
