Analysis of the image and corporate identity of the Colegio Mexicano de Reumatologia: Is it time to redefine it?

INTRODUCTION AND OBJECTIVES: The Colegio Mexicano de Reumatología (CMR) is a corporation whose brand has two elements-image and identity-that differentiate it from other corporations. We evaluated aspects of CMR's corporate image and identity. SUBJECTS AND METHODS: To assess corporate image, we designed a survey using proof-of-concept and discrete-choice-experiments approaches. It assessed which definition (orthopedist, rheumatologist, or rehabilitator) was most meaningful in four pain scenarios in healthy adults from the country's Western region. We used discourse analysis and five readability indices of the CMR website to assess corporate identity. RESULTS: In total, 700 respondents were included. For every rheumatologist chosen in the hand scenario, respondents chose 1.13 orthopedists and 0.70 rehabilitators. For every rheumatologist chosen in the knee scenario, respondents chose 2.36 orthopedists and 0.64 rehabilitators, whereas 0.85 orthopedists and 0.58 rehabilitators were chosen in the arthritis scenario. Only 38% of the respondents preferred the CMR's definition of a rheumatologist to describe a rheumatologist. The younger age group preferred orthopedists to rheumatologists (50% vs. 31%, p<0.001). In the arthritis scenario, the choice of rheumatologist increased from 27% in the elementary school group to 49% in the university group (p<0.001). Mother was the most influential in healthcare seeking. The discursive analysis revealed that the CMR is positioned as a "we" restricted to "colleagues;" the patient did not have agentive representation. The semiotic structure of the CMR's mission/vision was deemed imprecise and lacking in statements of value and purpose; the readability scores indicated that the text was challenging and dry. CONCLUSIONS: The CMR's corporate image does not differentiate it from other health providers. CMR's identity seems ambiguous with restricted directionality. It seems pertinent to redefine the CMR.

An update on the study of synovial fluid in the geriatric patient.

BACKGROUND: The characteristics of synovial fluid (SF) in geriatric patients differ from those in younger patients. In Mexico, epidemiologic data on the incidence of different rheumatic diseases in geriatric patients are scarce. OBJECTIVE: To describe the physical characteristics of geriatric SF and the prevalence of crystals in knee and other joint aspirates from patients with previously diagnosed joint disease. MATERIALS AND METHODS: A retrospective study was performed with a baseline of 517 SF samples between 2011 and 2023. White blood cell count was performed by Neubauer chamber and crystals were identified by polarized light microscopy. Descriptive statistical analysis was performed and prevalence was reported as a percentage. RESULTS: The mean age of the adults was 73.5±5.0 years, 54.4% were women and 45.6% were men. The mean SF volume was 6.3±9.5mL in older adults and 15.3±24.9mL in those younger than 65 years. The mean viscosity in older adults was 9.5±4.5mm and the mean leukocyte count was 7352±16,402leukocytes/mm3. Seventy percent of the older adults' SFs were referred to the laboratory for osteoarthritis (OA), with lower proportions for rheumatoid arthritis (RA) (14.6%) and gout (5.1%). Of the crystals observed in the geriatric population, 14.6% corresponded to monosodium urate crystals (CUM) and 18.9% to calcium pyrophosphate crystals (CPP). CONCLUSIONS: The characteristics of LS in older adults were smaller volume, increased viscosity, and non-inflammatory. The main diagnoses were OA, RA, and gout. The crystal content of the SF of the geriatric population corresponded mainly to CPP.

Takayasu's arteritis as an incidental finding in a patient with celiac disease: the importance of positron emission computed tomography.

BACKGROUND: Takayasu arteritis is a large-vessel vasculitis which affects large-caliber elastic arteries, primarily the aorta and its main branches. It mainly affects women between 20-30 years, so it is rare in children. CASE REPORT: We describe the case of a 15-year-old female who was followed up since she was 9 years old due to celiac disease. At the age of 13, anaemia of chronic disorders associated to elevated C-reactive protein and erythrocyte sedimentation were detected. The patient remained asymptomatic. After excluding other diseases, we requested a positron emission computed tomography (PET-CT); lesions compatible with large-vessel vasculitis were detected. Cardiology evaluation showed an aneurysm in the right coronary artery. Angio-CT suggested Takayasu type III arteritis. CONCLUSIONS: The delay in the diagnosis of Takayasu arteritis in pediatric patients is quite common. In this case, we have found phase II lesions, with no previous phase I symptoms. However, PET-CT allowed the diagnosis of vasculitis, key to the diagnosis of the patient.

INTRODUCCIÓN: La arteritis de Takayasu es una vasculitis de grandes vasos que afecta a las arterias elásticas de gran calibre, fundamentalmente la aorta y sus ramas principales. Ocurre frecuentemente en mujeres entre los 20-30 años, por lo que es muy infrecuente en la edad pediátrica. CASO CLÍNICO: Se presenta el caso de una paciente de 15 años en seguimiento desde los 9 años por enfermedad celiaca. A los 13 años se detectó anemia de trastornos crónicos, elevación de proteína C reactiva y velocidad de sedimentación globular. La paciente permaneció en todo momento asintomática. Tras descartar otros procesos, se solicitó tomografía computarizada por emisión de positrones (PET-TC), donde se detectaron lesiones compatibles con vasculitis de grandes vasos. La valoración por Cardiología evidenció un aneurisma en coronaria derecha. Se realizó angio-TC, que sugirió arteritis de Takayasu tipo III. CONCLUSIONES: Es frecuente un retraso en el diagnóstico de la arteritis de Takayasu en los pacientes pediátricos. En este caso se encontraron lesiones de la fase II sin la presencia de síntomas correspondientes a la fase I. El PET-TC permitió el diagnóstico de vasculitis, clave para el diagnóstico de la paciente.

Current status of musculoskeletal ultrasound in Colombian rheumatology

Introduction: Ultrasound is very useful in the management of rheumatological pathology today. Despite this, in Colombia, progress towards its implementation is limited and entails great difficulties. This deficit is also related to the difficulties in training new human talent. In Colombia, there is no study that identifies the current status of ultrasound among rheumatologists in the country. Methods: This is a descriptive cross-sectional study where medical specialists in Rheumatology practising in Colombia were surveyed through an online form. They were asked about general aspects and for their opinion regarding ultrasound in rheumatology and, if they practiced it, they were asked about specific aspects of its application in clinical practice. Additionally, questions were asked of the rheumatologists who are part of the specialist training processes in the country. Closed multiple-choice or Likert scale assessment questions were presented as required. The main objective was to describe the current use and opinion of musculoskeletal ultrasound in Colombian rheumatologists, as well as the limitations for its implementation. Frequency measurements were performed of the categorical variables of nominal type and ordinal type. The intention was to survey all rheumatologists in the country, who according to Colombian Society of Rheumatology data for the end of 2019 totalled 186. Results: Taking into account the number of rheumatologists of the Colombian Association of Rheumatology (Asoreuma) for 2019 totalling 186, a participation of 139 specialists (74.7%) was obtained, of which 22 of the respondents performed ultrasound in their daily practice (15.8%) the majority in this group being trained in Colombian territory (80.6%). Of the 139 respondents, 64.7% have received some type of training in ultrasound, generally pre-congress courses (22.5%), EULAR courses (16.7%) and training included in their residency curriculum outside the rheumatology service (9.8%). The acceptance of ultrasound is high among rheumatologists practicing in Colombia, 75.5% consider it important or very important and 84.9% indicated that for a comprehensive rheumatology service it is important or very important to have ultrasound. From the responses, however, they consider that its use could change their behaviour frequently, and very frequently in less than half of the cases at 46.7%. Regarding the opinion on the use of ultrasound in specific pathologies, rheumatoid arthritis (77.7%) and crystal arthropathies (72.7%) were considered the highest and most important, as well as in the performance of procedures at 87%. For decision-making in the inflammatory pathology study, 60.4% would consider performing ultrasound compared to 28.8% who responded MRI. Regarding the limitations for implementation, the lack of training in the country (25.6%), followed by the lack of resources to procure equipment (17.9%) and ignorance and lack of interest on the part of the health entities (17.1%) were the most recognized. Conclusion: Musculoskeletal ultrasound is only practiced by a minority of rheumatologists practicing in Colombia, even though the majority consider it important. Its importance lies in its use to treat patients with rheumatoid arthritis, crystal arthropathies and psoriatic arthropathy, as well as for the performance of procedures. More than half of the rheumatologists have received some type of training in ultrasound, usually very few hours' education and without practical or informal training, this being the main problem for its implementation.

Introducción: En la actualidad, la ecografía es de gran utilidad en el manejo de la patología reumatológica. A pesar de esto, en Colombia, los avances para su implementación son escasos y han enfrentado grandes dificultades. Este déficit también se encuentra relacionado con las complicaciones para la formación del nuevo talento humano. En Colombia no se dispone de ningún estudio en el que se identifique el estado actual de la ecografía entre los reumatólogos del país. Métodos: Se trata de un estudio descriptivo de carácter transversal en el cual se encuestó, por medio de un formulario on-line, a médicos especialistas en reumatología que hacen su práctica en el territorio colombiano. Se les preguntó acerca de los aspectos generales y su opinión sobre la ecografía en la reumatología, si la practicaban, como también en torno a los aspectos específicos de su aplicación en la práctica clínica. De manera adicional, se formularon preguntas dirigidas a aquellos reumatólogos que hacen parte de los procesos de capacitación de especialistas en el país; se presentaron preguntas cerradas de opción múltiple o de valoración por escala de Likert según se requirió. El objetivo principal fue describir el uso y la opinión actual sobre la ecografía musculoesquelética en reumatólogos colombianos, así como las limitantes para su implementación. A las variables categóricas de tipo nominal y de tipo ordinal se les hicieron medidas de frecuencia. Se pretendía encuestar a la totalidad de los reumatólogos en el país, los cuales, según información de la Asociación Colombiana de Reumatología (Asoreuma) de finales del 2019, eran 186. Resultados: De acuerdo con el número de reumatólogos proporcionado por la Asoreuma, de 186 especialistas en el año 2019, se obtuvo una participación de 139 de estos (74,7%), de los cuales 22 realizaban ecografía en su práctica diaria (15,8%), siendo este grupo en su mayoría formado en Colombia (80,6%). De los 139 encuestados, el 64,7% había recibido algún tipo de estudios en ecografía, generalmente cursos precongreso (22,5%), cursos de la Liga Europea Contra el Reumatismo (EULAR) (16,7%) y formación incluida en el pensum de su residencia fuera del servicio de reumatología (9,8%). La aceptación de la ecografía es alta entre los reumatólogos que ejercen en Colombia, el 75,5% la consideraron importante o muy importante. Asimismo, el 84,9% indicó que para un servicio de reumatología integral es importante o muy importante contar con ecografía. Sin embargo, los encuestados consideraron que su uso podría llegar a cambiar su conducta de manera frecuente, y muy frecuentemente en menos de la mitad de los casos (46,7%). Con respecto a la opinión sobre el uso de la ecografía en patologías específicas, se consideró con importancia y mucha importancia en artritis reumatoide (77,7%) y artropatías por cristales (72,7%), que fueron las más altas, así como para la realizaron de procedimientos (87%). Para la toma de decisiones en estudio de patología inflamatoria, el 60,4% consideraría realizar ecografía, comparado con 28,8% que se inclina por la resonancia. En relación con las limitaciones para la implementación, la falta de entrenamiento en el país (25,6%), seguida de la carencia de recursos para la consecución del equipo (17,9%) y el desconocimiento y la falta de interés por parte de los entes de salud (17,1%) fueron las más reconocidas. Conclusiones: La ecografía musculoesquelética solamente es practicada por una minoría de los reumatólogos que ejercen en Colombia, a pesar de que la mayoría la considera importante. Su relevancia radica en su uso para tratar a los pacientes con artritis reumatoide, artropatías por cristales y por artropatía psoriásica, así como para la realización de procedimientos. Más de la mitad de los reumatólogos ha recibido algún tipo de formación en ecografía, la mayoría de las veces educación de muy pocas horas o sin entrenamiento práctico, o no formal, lo cual constituye el principal problema para su implementación.

Acercamiento teórico al uso de la imagenología en el diagnóstico temprano de la artritis reumatoide / Theoretical approach to the use of imaging in the early diagnosis of rheumatoid arthritis

La artritis reumatoide es una enfermedad progresiva, con manifestaciones clásicas y tempranas como es la afectación de las articulaciones pequeñas de las manos y los tobillos. Se realizó una revisión bibliográfica de los documentos publicados entre 2017 y 2022. Se realizó una lectura preliminar de 37 artículos que cumplían con los criterios de inclusión, y finalmente se seleccionaron 23 artículos, de los cuales se tomó el contenido de mayor importancia. La ecografía es una técnica fiable y más sensible que la exploración clínica en el estudio de la enfermedad músculo-esquelética, pues permite una exploración multiplanar y dinámica, lo que resulta en un diagnóstico más exacto. La técnica Doppler constituye un complemento útil en el seguimiento de estos pacientes. Esta enfermedad es recurrente en las consultas de Reumatología, por tanto, en su valoración inicial, la utilidad de los medios diagnósticos, especialmente la ecografía, tiene gran importancia.

Rheumatoid arthritis is a progressive disease, with classic and early manifestations such as involvement of the small joints of the hands and ankles. We conducted a bibliographic review of the documents published between 2017 and 2022. A preliminary reading of 37 articles that met the inclusion criteria was carried out, and 23 articles were finally selected, from which the most important content was taken. Ultrasound is a more sensitive and reliable technique than clinical examination for the study of musculoskeletal disease, since it allows a multiplanar and dynamic examination, which results in a more accurate diagnosis. Doppler technique is a useful complement in the follow-up of these patients. This disease is recurrent in Rheumatology consultations, that's why in its initial assessment, the usefulness of diagnostic means, especially ultrasound, is of great importance.

Lúpus eritematoso sistêmico juvenil: manifestações clínicas, diagnóstico e tratamento / Juvenile systemic lupus erythematosus: clinical manifestations, diagnosis and treatment

Introdução: Lúpus eritematoso sistêmico juvenil é doença autoimune que se inicia em crianças e jovens com menos de 18 anos. Em comparação com a forma em adultos, ele geralmente apresenta maior morbidade, altas taxas de nefrite lúpica, manifestações reumatológicas e dermatológicas e envolvimento de mucosas. Objetivo: Revisão narrativa envolvendo alguns dos principais aspectos que concernem na doença. Métodos: Busca ativa no PubMed e Scielo, com textos em inglês e português entre 2016 e 2022, utilizando os seguintes descritores: lupus, pediatric, childhood, diagnosis. Foram eliminados artigos que não abordavam a população pediátrica ficando selecionados 12 artigos. Foram focados os aspectos gerais da doença, métodos diagnósticos, diagnósticos diferenciais, investigação laboratorial, manifestações clínicas e tratamento. Conclusão: Lúpus é doença que acomete tanto a população pediátrica quanto a adulta, mas há necessidade de mais estudos em crianças para o melhor entendimento das sutilezas que envolvem a doença em questão. Diante disso, é fundamental que os protocolos tanto de diagnóstico e tratamento, que hoje estão vigentes, sejam melhor entendidos e que mais estudos sejam realizados para aprimorar o manejo desses pacientes.

Introduction: Juvenile systemic lupus erythematosus is an autoimmune disease that begins in children and younger than 18 years. Compared with the disease in the adult, it usually has a higher morbidity, with high rates of lupus nephritis, rheumatologic and dermatologic manifestations, and mucosal involvement. Objective: To carry out a bibliographic review involving some of the main aspects concerning the disease. Methods: The research was carried out using articles in the PubMed and Scielo databases, with texts in English and Portuguese between 2016 and 2022. The search was carried out using the descriptors: lupus, pediatric, childhood, diagnosis. Articles that did not address the pediatric population were excluded. Thus, 12 articles were selected. Searched topics were: general aspects, diagnostic methods, differential diagnoses, laboratory investigation, clinical manifestations and treatment. Conclusion: Lupus is a disease that affects both the pediatric and adult populations, but there is a need for further studies in children to better understand the subtleties surrounding the disease in question. In view of this, it is essential that the protocols for both diagnosis and treatment, which are in force today, be better understood and more studies must be carried out to improve the management of these patients.

Qualidade de vida em pacientes com espondiloartrites: análise comparativa entre as formas axial, periférica pura e mista / Quality of life in spondyloarthritis: a comparison among axial, peripheric and mixed forms

Introdução: As espondiloartrites são doenças musculoesqueléticas crônicas que podem ter envolvimento axial, periférico ou misto. Devido ao grande comprometimento físico esta doença causa importante redução da qualidade de vida, mas não se sabe se isto acontece de igual maneira nas 3 formas. Objetivo: Estudar a associação entre qualidade de vida e formas de espondiloartrites. Método: Coletaram-se dados acerca de epidemiologia, perfil clínico, comorbidades e de qualidade de vida (através do SF-12 ou Short Form Health Survey­12 questions). Resultados: Incluíram-se 120 indivíduos: 60 EpA e 60 controles. O SF-12 físico tinha mediana de 38,05 para espondiloartrites e 55,1 para controle (p<0,0001). No quesito mental as medianas foram de 42,1 e 50,1 com p=0,04. Não foi possível demonstrar diferenças nos subgrupos de espondiloartrites, tanto no aspecto físico como mental (p=0,33 e 0,30 respectivamente). Conclusão: Existem diferenças significativas na qualidade de vida entre espondiloartrites e controles, mas não entre os subgrupos das espondiloartrites.

Introduction: Spondyloarthritis are chronic musculoskeletal diseases divided as axial, peripherical and mixed diseases. Due to a great physical involvement, it reduces patients' quality of life, but it is unknown how the 3 forms of the disease behave in such context. Objective: To study the quality of life association with spondyloarthritis forms. Methods: Data collection included: epidemiologic data, clinical profile, and quality of life data evaluated through the SF-12 (Short Form Health Survey­12 questions). Results: About 120 individuals were included: 60 spondyloarthritis and 60 controls. The physical SF-12 showed median of 38.05 for spondyloarthritis and 55.1 for controls (p<0.0001). The medians in mental SF-12 were 42.1 and 50.1 with p= 0.04. No differences in quality of life in the spondyloarthritis subgroups could be detected (with p=0.33 and 0.30 for physical and mental aspects). Conclusion: There was a significant difference in quality of life between spondyloarthritis sample and controls but not among the spondyloarthritis subgroups.

Arteritis de Takayasu como hallazgo incidental en un paciente con enfermedad celiaca: la importancia de la tomografía computarizada por emisión de positrones / Takayasu's arteritis as an incidental finding in a patient with celiac disease: the importance of positron emission computed tomography

Resumen Introducción: La arteritis de Takayasu es una vasculitis de grandes vasos que afecta a las arterias elásticas de gran calibre, fundamentalmente la aorta y sus ramas principales. Ocurre frecuentemente en mujeres entre los 20-30 años, por lo que es muy infrecuente en la edad pediátrica. Caso clínico: Se presenta el caso de una paciente de 15 años en seguimiento desde los 9 años por enfermedad celiaca. A los 13 años se detectó anemia de trastornos crónicos, elevación de proteína C reactiva y velocidad de sedimentación globular. La paciente permaneció en todo momento asintomática. Tras descartar otros procesos, se solicitó tomografía computarizada por emisión de positrones (PET-TC), donde se detectaron lesiones compatibles con vasculitis de grandes vasos. La valoración por Cardiología evidenció un aneurisma en coronaria derecha. Se realizó angio-TC, que sugirió arteritis de Takayasu tipo III. Conclusiones: Es frecuente un retraso en el diagnóstico de la arteritis de Takayasu en los pacientes pediátricos. En este caso se encontraron lesiones de la fase II sin la presencia de síntomas correspondientes a la fase I. El PET-TC permitió el diagnóstico de vasculitis, clave para el diagnóstico de la paciente.

Abstract Background: Takayasu arteritis is a large-vessel vasculitis which affects large-caliber elastic arteries, primarily the aorta and its main branches. It mainly affects women between 20-30 years, so it is rare in children. Case report: We describe the case of a 15-year-old female who was followed up since she was 9 years old due to celiac disease. At the age of 13, anaemia of chronic disorders associated to elevated C-reactive protein and erythrocyte sedimentation were detected. The patient remained asymptomatic. After excluding other diseases, we requested a positron emission computed tomography (PET-CT); lesions compatible with large-vessel vasculitis were detected. Cardiology evaluation showed an aneurysm in the right coronary artery. Angio-CT suggested Takayasu type III arteritis. Conclusions: The delay in the diagnosis of Takayasu arteritis in pediatric patients is quite common. In this case, we have found phase II lesions, with no previous phase I symptoms. However, PET-CT allowed the diagnosis of vasculitis, key to the diagnosis of the patient.

Custeio Baseado em Atividade e Tempo (TDABC) do modelo CEDMAC de terapia assistida para dispensação de medicamentos imunobiológicos para doenças reumatológicas no SUS / Time-Driven Activity Based Costing (TDABC) of the CEDMAC model of assisted therapy for dispensing immunobiological rheumatologic medications at SUS

Objetivos: Mensurar o custo dos procedimentos de infusão de imunobiológicos no modelo CEDMAC (Centro de Dispensação de Medicações de Alto Custo) e estimar o custo minimização integral gerada pela existência desse modelo. Métodos: A metodologia de Custeio Baseado em Atividade e Tempo (TDABC) foi usada para calcular os custos dos procedimentos. Tempos de atividades, capacidades máximas de atendimento e fluxos dos processos internos foram obtidos em entrevistas e validados por meio de acompanhamento de pacientes. Os procedimentos foram categorizados em três tipos: a) aplicação subcutânea, b) infusão endovenosa rápida e c) infusão endovenosa longa. O custo-minimização foi estimado a partir de análise de 2017 para pacientes com artrite reumatoide (AR). Resultados: Ao longo de 2019, foram realizados 12.074 atendimentos no CEDMAC. Desses atendimentos, 60% foram de aplicação subcutânea (custo de R$ 117,90), 30%, de infusão endovenosa rápida (custo de R$ 169,90) e 10%, de endovenosa longa (custo de R$ 217,50). Usando a análise realizada em 2017, foi possível calcular o custo-minimização integral do modelo (uma economia líquida estimada de R$ 1.258.024,26 ao ano) e também extrapolar esses valores para todo o SUS caso o modelo fosse difundido no país (uma economia líquida estimada de R$ 189.401.652,88). Conclusão: Utilizando o método de TDABC, foi possível realizar de maneira rápida e eficiente o custeio dos principais procedimentos realizados no modelo CEDMAC. Essa análise embasará a solicitação da incorporação desses procedimentos na tabela unificada do SUS. Caso os procedimentos sejam incorporados e o modelo CEDMAC, difundido pelo Brasil, estima-se que a economia gerada seja da ordem de 189 milhões de reais ao ano.

Objectives: To measure the costs of immunobiological infusion procedures in the CEDMAC model (Centro de Dispensação de Medicações de Alto Custo) and to estimate the full cost-minimization generated by the existence of this model. Methods: Time-Driven Activity Based Costing (TDABC) methodology was used to calculate the procedures costs. Activity times, service capacities and internal flows were obtained from employee interviews and validated by follow-up with patients. Procedures were categorized into three types: a) subcutaneous, b) intravenous fast infusion, and c) intravenous slow infusion. The full cost-minimization was estimated based on a 2017 analysis of the cost-minimization for rheumatoid arthritis (RA) patients. Results: In 2019, 12,074 patients were attended at CEDMAC. Of these, 60% of infusions were subcutaneous (costing R$ 117.90 each), 30% were fast intravenous infusion (costing R$ 169.90), and 10% were slow intravenous infusion (costing R$ 217.50). Using a 2017 RA analysis, it was possible to calculate the full cost-minimization of the model, with an estimated net savings of R$ 1,258,024.26 per year. The estimated net savings if the model were disseminated throughout the country for the entire SUS would be R$ 189,401,652.88. Conclusion: Using the TDABC method it was possible to quickly and efficiently estimate the cost allocation of the main procedures performed in the CEDMAC model. This analysis will support the request for incorporating these procedures into SUS. If the procedures were incorporated, and the CEDMAC model was disseminated throughout Brazil, the savings generated by this initiative could be up to 189 million reais per year.

Síndrome inflamatorio multisistémico en adultos: revisión sistemática y metaanálisis del espectro reumatológico de las complicaciones postinfecciosas de la COVID-19

Multisystem inflammatory syndrome in adults (MIS-A) is a rare but severe complication in adults infected with SARS-CoV-2. However, the pathophysiology remains elusive, as the limited number of reports preclude a broader understanding of this syndrome. We conducted this systematic review to explore the clinical spectrum of MIS-A, in particular its rheumato-logical manifestations. Meta-analyses of case-series were also performed. We identified 28 patients from 14 case reports and two case series of MIS-A. This disease occurred equally in both genders, with a mean age of 33 + 10 years old, and predominantly in those of African descent (40%). Rheumatological manifestations consisted of Kawasaki Disease (KD)-like symptoms. Ninety percent of patients had positive COVID-19 serology tests, while 48% of patients were negative for COVID-19 RT-PCR test. Twelve patients were admitted to ICU and unfortunately two died. Although the signs and symptoms of MIS mimicked KD, the gastrointestinal findings were more prominent in the former group. The demographic make-up was also different, with MIS-A occurring mostly in those of African descent. Importantly, unlike their paediatric counterparts, the adult group did not have coronary artery abnormalities. Long-term monitoring is needed as safety data is scarce. Of note, although the prognosis of MIS-A is excellent, the life-threatening nature of this syndrome demands intensive care unit level of care and mechanical support. During the COVID-19 pandemic, a constellation of KD symptoms in an adult patient should alert the clinician to the possibility of MIS-A. © 2021 Asociación Colombiana de Reumatología.

El espectro clínico del síndrome inflamatorio multisistémico en adultos (MIS-A) es una complicación rara, pero grave en adultos infectados por el coronavirus del síndrome respiratorio agudo grave de tipo 2. Realizamos una búsqueda bibliográfica en varias bases de datos, y también se hizo en metanálisis. Identificamos 28 pacientes de 14 informes de casos y 2 series de casos de MIS-A. Esta enfermedad se manifestó por igual en ambos sexos, con una edad media de 33 + 10 anos, y se presentó predominantemente en afrodescendientes (40%). Las manifestaciones reumatológicas consistieron en síntomas similares a la enfermedad de Kawasaki (EK). El 90% de los pacientes tuvo pruebas positivas de serología de la enfermedad por el coronavirus de 2019 (COVID-19), mientras que el 48% dio negativo para la prueba de reacción en cadena de la polimerasa con transcriptasa inversa de la COVID-19. Doce pacientes ingresaron en la unidad de cuidados intensivos y, lamentablemente, 2 fallecieron. Encontramos que, si bien los signos y los síntomas de MIS imitaban a EK, los hallazgos gastrointestinales eran más prominentes en el primer grupo. Además, la composición demográfica fue asimismo diferente, con MIS-A que se presentó principalmente en afrodescendientes. Es importante destacar que, a diferencia de sus homólogos pediátricos, el grupo de los adultos no experimentó anomalías en las arterias coronarias. Se necesita un seguimiento a largo plazo, ya que los datos de seguridad son escasos. Es de destacar que, aun cuando el pronóstico de MIS-A es excelente, la naturaleza potencialmente mortal de este síndrome exige el nivel de atención y el soporte mecánico de la unidad de cuidados intensivos. Durante la pandemia por la COVID-19, una constelación de síntomas de EK en un paciente adulto debe alertar al médico sobre la posibilidad de MIS-A.

Colchicina, perspectivas de un viejo amigo para la reumatología en la COVID-19: una revisión exploratoria / no

Introducción: La colchicina es ampliamente utilizada en enfermedades inflamatorias como la gota y la fiebre mediterránea familiar. Debido a su capacidad inmunomoduladora, podría tener un papel importante en el tratamiento de la COVID-19. Objetivo: Explorar la evidencia médica publicada hasta el 28 de diciembre del 2020, acerca de la eficacia y la seguridad de la colchicina en el tratamiento de pacientes con infección confirmada por SARS-CoV-2. Material y métodos: Revisión exploratoria de la literatura que incluyó PubMed y Scopus. Se tuvieron en cuenta registros de ensayos clínicos y publicaciones con datos empíricos (estudios observacionales y experimentales) en inglés y español. Resultados: Se encontraron 33 ensayos clínicos y 6 publicaciones empíricas: estudios de cohorte prospectivos (n = 2) y retrospectiva (n = 2), ensayo clínico aleatorizado (n = 1) y estudio casos y controles (n = 1). La suma de los participantes en los ensayos es de 46.324 individuos, el 73% (24/33) de los estudios recluta a la población de estudio y el 51% (17/33) son fase 3. Conclusiones: Un ensayo clínico respalda la disminución en marcadores inflamatorios pronósticos y el tiempo de estancia hospitalaria en la infección por SARS-CoV-2. Los ensayos clínicos en desarrollo ayudarán a esclarecer la eficacia y la seguridad de la colchicina para el manejo de pacientes con COVID-19.

Introduction: Colchicine is widely used to treat inflammatory diseases such as gout and Mediterranean fever. Due to its immunomodulatory capacity, it could play an important role in the treatment of COVID-19. Objective: To explore the current available medical evidence, published until 28 December 2020, regarding the efficacy and safety of colchicine in the treatment of patients with confirmed SARS-CoV-2 infection. Material and methods: Scoping review of the literature that included PubMed and Scopus. Records of clinical trials and publications with empirical data (observational and experimental studies) in English and Spanish were included. Results: A total of 33 clinical trials and 6 publications were found: prospective (n = 2) and retrospective (n = 2) cohort studies, randomised clinical trials (n = 1) and case-control studies (n = 1). The total number of participants in the trials is 46,324 individuals, 73% (24/33) of the studies are recruiting participants and 51% (17/33) are phase 3 studies. Conclusions: One clinical trial reports a decrease in prognostic inflammatory markers and length of hospital stay in SARS-CoV-2 infection. The ongoing clinical trials will clarify the efficacy and safety of colchicine for the management of patients with COVID-19.

Impacto de la pandemia por SARS-CoV-2 en la formación de los alumnos de la Carrera de Médico Especialista en Reumatología / Impact of the SARS-CoV-2 pandemic on a group of Rheumatology trainees of Argentina

Introducción: en 2020, la rápida evolución de la pandemia por SARS-CoV-2 desencadenó una emergencia sanitaria que generó una importante reorganización del sistema de salud, lo que llevó a la discontinuación y posterior adecuación de los sistemas de formación. El objetivo de este estudio fue describir el impacto de la pandemia en un grupo de reumatólogos en formación en la Ciudad Autónoma de Buenos Aires. Materiales y métodos: se envió una encuesta online por correo electrónico a los alumnos de la Carrera de Especialista en Reumatología de la Sociedad Argentina de Reumatología y de la Universidad de Buenos Aires. Incluyó 24 preguntas relacionadas con el impacto de la pandemia en diferentes aspectos de la formación y las nuevas estrategias educativas implementadas. Resultados: de 114 alumnos contactados, respondieron 79 (69,3%). Aproximadamente el 90% indicó que su formación se afectó. Un 46% consideró que la práctica médica y la actividad académica se comprometieron por igual y el 45% solo la práctica médica. Un 50% realizó tareas no relacionadas con su formación. El 57% suspendió temporalmente la asistencia a su centro. También informaron una reducción del 55% (DE 18,6) de las actividades relacionadas con la consulta. Conclusiones: la pandemia por SARS-CoV-2 afectó a los estudiantes de Reumatología al limitar sus actividades prácticas y académicas, y por deber realizar tareas ajenas a su formación en más de la mitad de los casos.

Introduction: in 2020, the rapid evolution of the SARS-CoV-2 pandemic triggered a health emergency, generating an important heath system reorganization which led to the discontinuation and subsequent adaptation of training systems. The objective was to describe the pandemic impact on a group of rheumatology trainees in Buenos Aires, Argentina. Materials and methods: an online survey was sent through e-mail to rheumatology specialist course trainees of Argentine Society of Rheumatology and University of Buenos Aires. It included 24 close-ended questions about the pandemic impact on different aspects of rheumatology training and the new implemented educational response strategies. Results: from 114 trainees contacted, 79 (69.3%) responded. Approximately 90% indicated that their rheumatology training was affected. Forty-six percent thought that medical practice and academic activity were equally affected and 45% that only medical practice was compromised. About 50% reported that they had to perform tasks unrelated to their training. Fifty-seven percent discontinued temporarily the training site attendance. Participants reported a mean reduction of 55% (SD 18.6) of activities related to patient care. Conclusions: the SARS-CoV-2 pandemic affected rheumatology trainees, by limiting their practical and academics activities, and having to perform tasks unrelated to their training in more than a half.

O poeta não existe mais: Pedro Nava e os impasses da institucionalização da reumatologia no Brasil, 1949-1961 / Gone is the poet: Pedro Nava and the impasses in the institutionalization of rheumatology in Brazil, 1949-1961

Resumo O artigo analisa um aspecto pouco conhecido da trajetória de Pedro Nava: seu envolvimento na institucionalização da reumatologia no Brasil. Por meio de uma gama de materiais de arquivo, como revistas médicas, correspondência, cadernetas, relatórios técnicos e matérias de jornal, procura recuperar diversos mecanismos mobilizados por Nava no movimento de legitimação de uma nova área da medicina no Brasil a partir dos anos 1940. Como se busca demonstrar, seus esforços incluíram a criação de redes no exterior, a fundação de departamentos, a participação ativa no periódico Brasil Médico , o desenvolvimento de um léxico próprio para a reumatologia, relações com o Estado e a criação de associações.

Abstract A little-known facet of the trajectory of Pedro Nava is analyzed, namely, his involvement in the institutionalization of rheumatology in Brazil. Drawing on multiple primary sources, including medical journals, correspondence, notebooks, technical reports, and newspaper stories, the range of mechanisms Nava galvanized in the effort to legitimize this new area of medicine in Brazil as of the 1940s are shown. These include his efforts to forge networks outside the country, create new departments, take active part in the journal Brasil Médico, develop a specialized lexicon for rheumatology, liaise with the State, and found new associations.
