Precordial pain, leukocytosis and bicytopenia in a teenager with systemic juvenile idiopathic arthritis under immunosuppressive therapy / Dor precordial, leucocitose e bicitopenia em adolescente com artrite idiopática juvenil sistêmica em terapia imunossupressora

ABSTRACT Objective: To highlight the importance of the new classification criteria for the macrophage activation syndrome (MAS) in systemic juvenile idiopathic arthritis in order to reduce morbidity and mortality outcome related to this disease. Case description: A 12-year-old female patient with diagnosis of systemic juvenile idiopathic arthritis under immunosuppression therapy for two years developed cough, acute precordial chest pain, tachypnea, tachycardia and hypoxemia for two days. Chest tomography showed bilateral laminar pleural effusion with bibasilar consolidation. The electrocardiogram was consistent with acute pericarditis and the echocardiogram showed no abnormalities. Laboratory exams revealed anemia, leukocytosis and increased erythrocyte sedimentation rate, as well as C-reactive protein rate and serum biomarkers indicative of myocardial injury. Systemic infection and/or active systemic juvenile idiopathic arthritis were considered. She was treated with antibiotics and glucocorticoids. However, 10 days later she developed active systemic disease (fever, evanescent rash and myopericarditis with signs of heart failure) associated with macrophage activation syndrome, according to the 2016 Classification Criteria for Macrophage Activation Syndrome in Systemic Juvenile Idiopathic Arthritis. She was treated for five days with pulse therapy, using glucocorticoids, immunoglobulin and cyclosporine A, with improvement of all clinical signs and laboratory tests. Comments: Myopericarditis with signs of heart failure associated with MAS is a rare clinical presentation of systemic juvenile idiopathic arthritis. Macrophage activation syndrome occurs mainly during periods of active systemic juvenile idiopathic arthritis and may be triggered by infection. Knowledge about this syndrome is crucial to reduce morbidity and mortality.

RESUMO Objetivo: Destacar a importância do conhecimento sobre os novos critérios de classificação para síndrome de ativação macrofágica (SAM) na artrite idiopática juvenil sistêmica para reduzir a morbidade e mortalidade desse desfecho. Descrição do caso: Adolescente do sexo feminino de 12 anos de idade, em terapia imunossupressora por diagnóstico de artrite idiopática juvenil sistêmica há 2 anos, com quadro de tosse, dor precordial aguda, taquipneia, taquicardia e hipoxemia há 2 dias. A tomografia de tórax evidenciou efusão pleural laminar bilateral com consolidação bibasal. O eletrocardiograma foi compatível com pericardite aguda, e o ecocardiograma foi normal. Os exames laboratoriais revelaram anemia, leucocitose e aumento da velocidade de hemossedimentação, proteína C-reativa e marcadores séricos de lesão miocárdica. Infecção sistêmica e/ou doença sistêmica em atividade foram consideradas. A paciente foi tratada com antibióticos e glicocorticoide. Entretanto, dez dias depois, evoluiu com doença sistêmica em atividade (febre, exantema e miopericardite com insuficiência cardíaca) associada à SAM, de acordo com o 2016 Classification Criteria for Macrophage Activation Syndrome in Systemic Juvenile Idiopathic Arthritis, e necessitou de cinco dias de pulsoterapia com glicocorticoide, imunoglobulina e ciclosporina A, com melhora de todos os parâmetros clínicos e laboratoriais. Comentários: A miopericardite com sinais de insuficiência cardíaca associada à SAM é uma apresentação clínica rara da artrite idiopática juvenil sistêmica, que ocorre principalmente em períodos de atividade sistêmica da doença e pode ser deflagrada por infecções. O conhecimento sobre essa síndrome é fundamental para reduzir morbidade e mortalidade desse grave desfecho.

Sonographic evaluation of salivary glands in juvenile Sjögren's syndrome.

IIntroduction: Sjögren's syndrome in childhood is a rare autoimmune disease and mostly under-diagnosed. The aim of this study is to highlight the importance of ultrasonographic assessment of the salivary glands in children with recurrent parotitis and positive autoantibodies. Two cases of ultrasonographic patterns typical of Sjögren's syndrome have been described below. Case 1: Female, 7 years old, reporting for 2 years recurrent parotitis, xerophthalmia, xerostomia, polyarthralgia and fever. Immunological tests were positive for antinuclear antibodies, rheumatoid factor, anti-SSA/Ro and anti-SSB/La. Salivary glands ultrasound was consistent with Grade 4 by the B-mode method and the spectral Doppler with presence of intense Power Doppler signal and decreased vessels internal resistance, supporting the diagnosis of juvenile Sjögren's syndrome. Case 2: Female, 10 years old, reporting recurrent parotitis for 1 year and polyarthritis for 10 days. The supplementary tests revealed positive antibodies for Sjögren's syndrome. Salivary glands Ultrasound and Spectral Doppler were consistent with chronic and active inflammatory process of the salivary glands in the juvenile Sjögren's syndrome. DISCUSSION: Salivary glands ultrasound can be a useful exam in the diagnosis of juvenile Sjögren's syndrome.

Osteonecrosis of the jaw on imaging exams of patients with juvenile systemic lupus erythematosus.

OBJECTIVE: The objective of the present study was to evaluate radiographic changes of the temporomandibular joint (TMJ) in patients with juvenile systemic lupus erythematosus (JSLE) and a control group. PATIENTS AND METHODS: Panoramic radiographies of the TMJ of 26 JSLE patients and 28 healthy individuals were evaluated. Multislice computed tomography (MCT) was performed on those patients who presented flattening and/or destruction of mandibular condyles. Demographic data, oral health indices, clinical manifestations, laboratory exams, and treatment were evaluated. RESULTS: Important radiographic changes consistent with osteonecrosis of the mandible, confirmed by MCT of the TMJ, were observed in 2/26 (8%) JSLE patients versus 0% in the control group (P = 0.22). Mild clinical dysfunction and abnormal TMJ mobility were observed in 67% and 54% of the patients, respectively. Age of onset, disease duration, and current age were similar in JSLE patients with and without severe radiographic changes of TMJ (9.3 versus 10.8 years, P = 0.77; 3.3 versus 2 years, P = 0.63; 12.6 versus 13.5 years, P = 0.74, respectively). Significant differences in gender, socioeconomical status, oral health indices, clinical manifestations, laboratory exams, and treatment were not observed between both subgroups (P 0.05). Both JSLE patients with osteonecrosis of the mandible had active chronic disease, used corticosteroids for a prolonged period, and had mild TMJ dysfunction. Antiphospholipid antibodies were not observed in those two patients, and neither one had been treated with bisphosphonate. CONCLUSIONS: Osteonecrosis of the mandible with mild TMJ dysfunction was observed in some of the patients, demonstrating the importance of odontological assessment during clinical follow-up.

Osteonecrose de mandíbula em pacientes com lúpus eritematoso sistêmico juvenil observada em exame de imagem / Osteonecrosis of the jaw on imaging exams of patients with juvenile systemic lupus erythematosus

OBJETIVO: O objetivo deste estudo foi avaliar alterações radiográficas da articulação temporomandibular (ATM) em pacientes com lúpus eritematoso sistêmico juvenil (LESJ) e controles. PACIENTE E MÉTODOS: Vinte e seis pacientes com LESJ e 28 controles foram avaliados com radiografia panorâmica da ATM. Tomografia computadorizada multislice (TCM) da ATM foi realizada naqueles que tiveram achatamento e/ou destruição dos côndilos mandibulares. Foram avaliados dados demográficos, índices de saúde bucal, manifestações clínicas, exames laboratoriais e tratamentos. RESULTADOS: Alterações radiográficas importantes compatíveis com osteonecrose de mandíbula e confirmadas pela TCM da ATM foram observadas em 2/26 (8 por cento) de LESJ versus 0 por cento do grupo controle (P = 0,22). Disfunção clínica leve e mobilidade alterada de ATM foram observadas em 67 por cento e 54 por cento, respectivamente. A idade de início, duração da doença e idade atual foram semelhantes nos pacientes com LESJ com e sem alterações radiográficas graves da ATM (9,3 versus 10,8 anos, P = 0,77; 3,3 versus 2 anos, P = 0,63; 12,6 versus 13,5 anos, P = 0,74; respectivamente). Assim como não foram evidenciadas diferenças estatísticas em ambos os grupos com relação a sexo, classe socioeconômica, índices de saúde bucal, manifestações clínicas, exames laboratoriais e tratamentos (P > 0,05). Esses dois pacientes com LESJ e osteonecrose de mandíbula tiveram curso crônico ativo da doença, utilizaram corticosteroides por um longo período e apresentaram disfunção clínica leve da ATM. Nenhum deles teve anticorpos antifosfolipídeos e não foram tratados previamente com bisfosfonatos. CONCLUSÕES: Osteonecrose de mandíbula com leve disfunção clínica da ATM foi observada em alguns pacientes, demonstrando a importância da avaliação odontológica durante o acompanhamento clínico.

Situação dos afogamentos em duas regiões do interior do estado de São Paulo / Drowning situation in two non-coastal regions of São Paulo State, Brazil

Objetivo: Desenhar o perfil dos afogamentos em duas regiões do Estado de São Paulo. O afogamento representa uma causa de morte violenta importante em vários países. No Brasil, existem poucos dados referentes aos óbitos e seqüelas dos quase afogamentos, com variabilidade de estado para estado.Métodos: Foram levantados os óbitos registrados no Instituto Médico Legal, ocorridos em duas regiões do Estado de São Paulo: Campinas e Ribeirão Preto. Resultados: O estudo revelou contrastes relacionados com a bacia hidrográfica e com as áreas de lazer de cada região. Não ocorreram diferenças em relação ao gênero dos indivíduos envolvidos, havendo predomínio do masculino em ambas as regiões estudadas; em relação à faixa etária, foram os mais jovens e as crianças os envolvidos mais freqüentes. Os meses quentes mostraram maior freqüência de acidentes fatais, como em outras regiões do País. Conclusão:Medidas preventivas e educacionais são necessárias
