Enfrentamiento del paciente con poliartralgias y poliartritis / Patient's facing polyarthralgia and polyarthritis

El dolor articular es un motivo de consulta frecuente en la práctica clínica. La distinción del tipo de dolor, su distribución, los síntomas acompañantes, el examen físico y la evaluación de algunos exámenes de laboratorio ayudan a orientar acerca de las posibles causas y a pesquisar enfermedades graves que pueden causar destrucción articular o compromiso de otros órganos, con el fin de dar tratamiento oportuno y eficaz. En este artículo se dan algunas pautas que se pueden realizar en la consulta de Atención Primaria para distinguir cuadros de poliartralgias y poliartritis agudas y crónicas. Además, se dan nociones de algunas de las enfermedades reumatológicas más frecuentes.

Joint pain is a frequent reason for consultation in clinical practice. The distinction of the type of pain, its distribution, the accompanying symptoms, the physical examination and the evaluation of some laboratory test help to guide about the possible causes and to investigate serious diseases that can cause joint destruction or involvement other organs, in order to provide timely and effective treatment. This article gives some guidelines that can be carried out in the Primary Care consultation to distinguish acute and chronic polyarthralgia and polyarthritis. In addition, notions of some of the most frequent rheumatological diseases are given.

Artritis crónica en una paciente pediátrica posterior a Chikungunya / Chronic arthritis in a pediatric patient following Chikungunya

Resumen El virus Chikungunya produce una enfermedad de reciente aparición y creciente incidencia en Costa Rica. Las manifestaciones crónicas de la enfermedad se consideran de importancia en el área de la reumatología. La paciente presentó factores de riesgo para cronicidad como el sexo, la duración y severidad de la fase aguda, el número de articulaciones comprometidas y la asociación con el síndrome de activación macrofágica. En una artritis idiopática juvenil, que es el principal diagnóstico diferencial, se esperaría un inicio más insidioso y no agudo como en este caso; además, la paciente no presentó hepatomegalia o serositis e inicialmente no tuvo trombocitosis, pero manifestó un síndrome de activación macrofágica, que es una complicación inflamatoria descrita en artritis idiopática juvenil. La remisión del cuadro de artritis crónica con el uso de metotrexate, no ayuda al diagnóstico diferencial, porque se ha reportado que este es el tratamiento crónico de elección en ambas patologías. En este reporte se presenta el caso de una paciente pediátrica que ingresó con un cuadro agudo de Chikungunya confirmado serológicamente, y que evolucionó con criterios de una artritis idiopática juvenil sistémica y un síndrome de activación macrofágica secundario.

Abstract Chikungunya virus produce a disease of recent emergence and increasing incidence in Costa Rica. Chronicmanifestations of the disease are considered of importance in the rheumatology area. The patient presented risk factors for chronicity such as sex, the duration and severity of the acute phase, the number of joints involved, and the association with macrophage activation syndrome. In juvenile idiopathic arthritis, which is the main differential diagnosis, a more insidious and non-acute onset would be expected, as in this case, in addition, the patient did not present hepatomegaly or serositis and initially did not have thrombocytosis, but had a macrophage activation syndrome, which is an inflammatory complication described in juvenile idiopathic arthritis. Remission of the chronic arthritis condition with the use of methotrexate does not help the differential diagnosis, because it has been reported that this is the chronic treatment of choice in both pathologies. This report presents the case of a pediatric patient who was admitted with an acute episode of Chikungunya confirmed serologically and who evolved with systemic juvenile idiopathic arthritis criteria and secondary macrophage activation syndrome.

Infecciones osteoarticulares en un hospital pediátrico de alta complejidad: epidemiología y características clínicas asociadas con bacteriemia / Osteoarticular infections in a tertiary care children's hospital: Epidemiology and clinical characteristics in association with bacteremia

Introducción. Las infecciones osteoarticulares son una importante causa de morbilidad y pueden presentar bacteriemia. La epidemiología de estas infecciones se ha modificado en los últimos años. Objetivos. Describir las características epidemiológicas, clínicas y evolutivas de los niños con infecciones osteoarticulares y comparar los pacientes con bacteriemia con los que no la presentaron. Población y métodos. Cohorte retrospectiva. Se incluyeron pacientes menores de 18 años, admitidos en el Hospital Juan P. Garrahan entre el 1/1/2016 y el 31/12/2016 con sospecha de infecciones osteoarticulares en quienes se hubiese realizado artrocentesis y/o biopsia articular. Se excluyeron niños con patología previa. Se compararon las características clínicas y de laboratorio según tuvieran bacteriemia o no. Se utilizó Stata 10. Resultados. N: 62. La mediana de edad fue 59.5 meses (rango intercuartilo -RIC- 24-84). Presentaron fiebre 44 pacientes (70%). Predominaron las artritis (54 pacientes, 87%). Se identificó un agente etiológico en 29 pacientes (47%). Predominó Staphylococcus aureus (n: 20, 32%). Tuvieron bacteriemia 15 de ellos (24%). Recibieron clindamicina como tratamiento empírico 56 pacientes (90%). La mediana de tratamiento endovenoso fue 7 días (RIC 5-11) y de internación, 7 días (RIC 4-12). Los pacientes con bacteriemia tuvieron menor edad (26 meses vs. 60, p < 0,05), mayor valor de proteína C reactiva inicial (101 vs. 33 U/L, p < 0,05), menor valor de hemoglobina al ingresar (10,8 g/dl vs. 12.5 g/dl, p 0,04) y mayor frecuencia de fiebre (100% vs. 57%, p < 0,05). Conclusiones. Predominó Staphylococcus aureus. Los niños con bacteriemia tuvieron menor edad, mayor valor de proteína C reactiva, menos hemoglobina al ingresar y, más frecuentemente, fiebre.

Introduction. Osteoarticular infections are an important cause of morbidity and may present with bacteremia. The epidemiology has changed in recent years. Objectives. To describe the epidemiological, clinical, and evolutionary characteristics of children with osteoarticular infections and compare patients with and without bacteremia. Population and methods. Retrospective cohort. Patients younger than 18 years admitted between January 1st, 2016 and December 31st, 2016 suspected of osteoarticular infections who had undergone an arthrocentesis and/or joint biopsy were included. Clinical and laboratory characteristics were compared between patients with and without bacteremia. The Stata 10 software was used.Results. N: 62. Patients' median age was 59.5 months (interquartile range [IQR]: 24-84). Fever developed in 44 patients (70%). Arthritis predominated (54 patients, 87%). An etiologic agent was identified in 29 patients (47%). Staphylococcus aureus was prevalent (n: 20, 32%). Among these, 15 developed bacteremia (24%). Clindamycin was administered to 56 patients (90%) as empirical therapy. The median intravenous treatment duration was 7 days (IQR: 5-11) and the median length of stay, 7 days (IQR: 4-12). Patients with bacteremia were younger (26 months versus 60 months, p < 0.05), had a higher baseline C-reactive protein level (101 U/L versus 33 U/L, p < 0.05), a lower hemoglobin level at the time of admission (10.8 g/dL versus 12.5 g/dL, p = 0.04), and a higher frequency of fever (100% versus 57%, p < 0.05).Conclusions. Staphylococcus aureus was prevalent. Children with bacteremia were younger, had a higher C-reactive protein level, a lower hemoglobin level at the time of admission, and 100% presented fever

Oligoartritis, paniculitis y pioderma gangrenoso como manifestaciones de un Linfoma no Hodgkin / Oligoarthritis, panniculitis and pyoderma gangrenosum associated with non-Hodgkin lymphoma: report of one case

An assortment of clinical and laboratory abnormalities may occur as paraneoplastic syndromes in lymphomas. Rheumatological and dermatological manifestations such as paraneoplastic arthritis and pyoderma gangrenosum must be underscored. We report a 28 years old woman who developed pyoderma gangrenosum and two years later presented with arthritis of knees and ankles associated with panniculitis interpreted as erythema induratum that was pathologically confirmed. She developed a reactivation of pyoderma gangrenosum, that was refractory to treatment. Complementary studies showed a pulmonary nodule and a right paravertebral mass with involvement of the psoas muscle. Biopsies of both masses and a new pathological skin study demonstrated a large B-cell non-Hodgkin's lymphoma.

Avaliação de um controle estratégico da artrite encefalite caprina em rebanho caprino leiteiro / Evaluation of strategic control of caprine arthritis- encephalitis in dairy herd goats

O objetivo deste trabalho foi avaliar a utilização periódica de testes de diagnóstico mais sensíveis aliados às práticas de manejo, visando ao controle eficaz da artrite encefalite caprina (CAE). Foram realizadas oito coletas de sangue em matrizes e reprodutores. Da primeira à sétima análise, as coletas foram quadrimestrais, utilizando-se os testes de imunodifusão em gel de agarose (IDGA), ensaio imunoenzimático indireto (ELISA-i) e Western Blot (WB). A oitava coleta aconteceu seis meses após a sétima, utilizando-se o WB e a reação em cadeia de polimerase (PCR). A prevalência da CAE foi de 6,8%, 14,9% e 39,2% no IDGA, ELISA-i e WB, respectivamente. Na última análise, foram detectados 0,9% de animais positivos pelo WB e 10,8% pela PCR. Apesar de não erradicarem a CAE, as medidas adotadas, aliadas à utilização periódica dos testes sorológicos e à combinação com a PCR, foram importantes para reduzir significativamente os animais soropositivos no rebanho.(AU)

The aim of this study was to evaluate the periodic use of more sensitive diagnostic tests associated to management practices for the effective control of caprine arthritis-encephalitis (CAE). We carried out eight blood samples in does and bucks. From the first to the seventh analysis, the samples were quarterly, using Agarose Gel Immunodiffusion (AGID), Enzyme linked immunosorbent assay (i-ELISA) and Western Blot (WB) tests. The eighth collection was made six months after the seventh, using the WB and Polymerase Chain Reaction (PCR). The prevalence of CAE was 6.8%, 14.9% and 39.2% in the AGID, i-ELISA and WB respectively. The last analysis detected 0.9% of animals positive by WB and 10.8% by PCR. Although they do not eradicate CAE, steps taken together with the periodic use of serological tests and the combination with PCR were important to significantly reduce positive animals in the herd.(AU)

Monoartritis del codo e infarto óseo como presentación inicial de enfermedad linfoproliferativa / Elbow monoarthritis and bone infarction as a form of presentation of B cell lymphoma: case report

We report a 68-year-old woman presenting with pain and swelling in her left elbow. An elbow magnetic resonance with gadolinium evidenced bone marrow infiltration and a bone infarct. Given these findings, a body CT scan was performed which showed multiple mesenteric adenopathies and a large retroperitoneal mass. A lymph node biopsy confirmed a B cell lymphoma. Monoarthritis with no systemic manifestations represents a highly uncommon form of presentation of lymphoma. Moreover it usually affects inferior limbs, particularly in the presence of bone infarction.

A case of chikungunya virus disease presenting with remarkable acute arthritis of a previously damaged finger joint

Abstract: Chikungunya virus (CHIKV) is a mosquito-borne arthritogenic alphavirus that has recently been introduced to Brazil. We report the case of a 36-year-old male patient from the City of Rio de Janeiro who developed molecularly-confirmed CHIKV disease and whose clinical picture was remarkable because of acute arthritis of an interphalangeal joint that had been damaged by trauma 8 years previously. This case illustrates that acute CHIKV disease may preferentially target previously damaged joints. Careful study of individual cases may provide valuable information on the presentation and management of this emerging zoonosis in Brazil.

Formulation and evaluation of topical herbal gel for the treatment of arthritis in animal model

ABSTRACT The objective of the study is to formulate and evaluate a topical herbal gel containing Cardiospermum halicacabum and Vitex negundo leaf extracts for their anti-arthritic activity in rats. Twelve herbal gel formulations were prepared using 1.5% of gelling agents carbopol 934 (F1-F6) and carbopol 940 (F6-F12) and they were evaluated for physical appearance, net content, viscosity, extrudability, pH, spreadability, in vitro diffusion profile and primary skin irritation tests. The stability study for the topical herbal gel formulation was done as per ICH guidelines and anti-arthritic activity was evaluated by Freund's Complete Adjuvant (FCA) induced arthritis method. Assessment of body weight, paw volume, hematological and biochemical parameters, histopathological examination and In vitro determination of serum biomarkers were also carried out. Formulated gels were homogenous, stable and complied with the guidelines. Among the formulations, F4 showed better release (98.4 %) characteristics than other formulations. No erythema or edema was observed in the skin irritation test confirming the gel was non-toxic and safe. Topical application of the herbal gel F4 containing carbopol 934 displayed significant (p < 0.001) anti-arthritic activity compared to diseased rats. Reduction in paw volume, no agglutination in C - reactive protein and rheumatic factor, reduction in TNF level, regaining of normal hematological, and biochemical parameters, reduction in spleen and thymus weight and histopathological examination supported the anti-arthritic activity of the gel formulation.

Musculoskeletal manifestations and autoantibodies in children and adolescents with leprosy / Manifestações musculoesqueléticas e autoanticorpos em crianças e adolescentes com hanseníase

Objective: To evaluate musculoskeletal involvement and autoantibodies in pediatric leprosy patients. Methods: 50 leprosy patients and 47 healthy children and adolescents were assessed according to musculoskeletal manifestations (arthralgia, arthritis, and myalgia), musculoskeletal pain syndromes (juvenile fibromyalgia, benign joint hypermobility syndrome, myofascial syndrome, and tendinitis), and a panel of autoantibodies and cryoglobulins. Health assessment scores and treatment were performed in leprosy patients. Results: At least one musculoskeletal manifestation was observed in 14% of leprosy patients and in none of the controls. Five leprosy patients had asymmetric polyarthritis of small hands joints. Nerve function impairment was observed in 22% of leprosy patients, type 1 leprosy reaction in 18%, and silent neuropathy in 16%. None of the patients and controls presented musculoskeletal pain syndromes, and the frequencies of all antibodies and cyoglobulins were similar in both groups (p > 0.05). Further analysis of leprosy patients demonstrated that the frequencies of nerve function impairment, type 1 leprosy reaction, and silent neuropathy were significantly observed in patients with versus without musculoskeletal manifestations (p = 0.0036, p = 0.0001, and p = 0.309, respectively), as well as multibacillary subtypes in leprosy (86% vs. 42%, p = 0.045). The median of physicians' visual analog scale (VAS), patients' VAS, pain VAS, and Childhood Health Assessment Questionnaire (CHAQ) were significantly higher in leprosy patients with musculoskeletal manifestations (p = 0.0001, p = 0.002, p = 0002, and p = 0.001, respectively). Conclusions: This was the first study to identify musculoskeletal manifestations associated with nerve dysfunction in pediatric leprosy patients. Hansen's disease should be included in the differential diagnosis of asymmetric arthritis, especially in endemic regions. .

Objetivo: Avaliar o envolvimento musculoesquelético e os autoanticorpos em pacientes pediátricos com hanseníase. Métodos: Foram avaliados 50 pacientes com hanseníase e 47 crianças e adolescentes saudáveis de acordo com manifestações musculoesqueléticas (artralgia, artrite e mialgia), síndromes dolorosas musculoesqueléticas (fibromialgia juvenil, síndrome de hipermobilidade articular benigna, síndrome miofascial e tendinite) e painel de autoanticorpos e crioglobulinas. Escores de avaliação de saúde e tratamento foram realizados nos pacientes com hanseníase. Resultados: Pelo menos uma manifestação musculoesquelética foi observada em 14% dos pacientes com hanseníase e em nenhum controle. Dentre os pacientes com hanseníase, cinco tinham poliartrite assimétrica das pequenas articulações das mãos. Comprometimento da função do nervo foi observado em 22% dos pacientes com hanseníase, reação tipo I hansênica em 18% e neuropatia silenciosa em 16%. Nenhum dos pacientes e controles apresentou síndromes de dor musculoesquelética e as frequências dos anticorpos e crioglobulinas foram semelhantes nos dois grupos (p > 0,05). Comprometimentos da função nervosa, reação hansênica tipo I e neuropatia silenciosa foram observados em pacientes com vs sem manifestações musculoesqueléticas (p = 0,0036, p = 0,0001 e p = 0,309, respectivamente), bem como subtipos de hanseníase multibacilar (86% vs 42%, p = 0,045). A escala visual analógica (EVA) do médico, dos pacientes, e da dor e o Questionário de Avaliação de Saúde Infantil foram maiores em pacientes com manifestações musculoesqueléticas (p = 0,0001, p = 0,002, p = 0002 e p = 0,001, respectivamente). Conclusão: Este foi o primeiro ...

Sarcoidosis aguda: variante de Síndrome de Lõfgren sin eritema nodoso / Acute sarcoidosis: erythema nodosum-free variant of Lõfgren’s Syndrome

El síndrome de Lõfgren, es una variante aguda de la sarcoidosis, que se caracteriza por fiebre, eritema nodoso, adenomegalias hiliares pulmonares y artritis. En general, tiene un curso benigno y autolimitado, que contrasta con las formas crónicas que requieren uso de corticoides y tienen tendencia a la recidiva. Se describe aquí el caso clínico de un paciente joven, de sexo masculino, con artritis pero sin eritema nodoso, lo que dificultó el planteo diagnóstico de síndrome de Lõfgren. Se realiza además una breve descripción comparativa entre la presentación clínica de la sarcoidosis crónica y el síndrome de Lõfgren...

Meningoencefalite linfomonocitária crônica, oligoartrite e eritema nodoso: relato de síndrome de Baggio-Yoshinari de longa e recorrente evolução / Chronic lymphomonocytic meningoencephalitis, oligoarthritis and erythema nodosum: report of Baggio-Yoshinari syndrome of long and relapsing evolution

A borreliose humana brasileira, também conhecida como Síndrome de Baggio-Yoshinari (SBY), é uma enfermidade infecciosa própria do território brasileiro, transmitida por carrapatos não pertencentes ao complexo Ixodes ricinus, causada por espiroqueta do gênero Borrelia e que apresenta semelhanças clínicas e laboratoriais com a Doença de Lyme (DL). A SBY distingue-se da DL por apresentar evolução clínica prolongada, com episódios de recorrência e importante disfunção autoimune. Descreveremos o caso de uma paciente jovem, que desenvolveu progressivamente durante cerca de um ano oligoartrite de grandes articulações, seguida de distúrbio do cognitivo, meningoencefalite e eritema nodoso. O diagnóstico foi firmado devido à concomitância de queixas articulares e neurológicas com sorologia positiva para Borrelia burgdorferi sensu stricto. A paciente foi medicada com ceftriaxone 2 g/EV/dia por 30 dias, seguido de dois meses de doxiciclina 100 mg duas vezes ao dia. Houve remissão dos sintomas e normalização dos exames sorológicos para a borreliose. A SBY é uma zoonose emergente descrita apenas no Brasil, cuja frequência tem crescido bastante, e que, em razão das importantes diferenças nos aspectos epidemiológicos, clínicos e laboratoriais em relação à DL, merece especial atenção da classe médica do país. Trata-se de zoonose camuflada e de difícil diagnóstico, mas este deve ser perseguido com tenacidade, pois a enfermidade responde aos antibióticos no estágio inicial, podendo evoluir com sequelas neurológicas e articulares nos casos reconhecidos tardiamente ou recorrentes.

The Brazilian human borreliosis, also known as Baggio-Yoshinari Syndrome (BYS), is a tickborne disease but whose ticks do not pertain to the Ixodes ricinus complex. It is caused by Borrelia burgdorferi sensu lato microorganisms and resembles clinical and laboratory features of Lyme disease (LD). BYS is also distinguished from LD by its prolonged clinical evolution, with relapsing episodes and autoimmune dysfunction. We describe the case of a young female who, over one year, progressively presented with oligoarthritis, cognitive impairment, menigoencephalitis and erythema nodosum. Diagnosis was established by means of the clinical history and a positive serology to Borrelia burgdorferi sensu strictu. The patient received Ceftriaxone 2 g IV/day during 30 days, followed by 2 months of doxicycline 100 mg bid. Symptoms remitted and the Borrelia serology tests returned to normality. BYS is a new disease described only in Brazil, which has a raising frequency and deserves the attention from the country´s medical board because of clinical, epidemiological and laboratory differences from LD. Despite the fact that it is a hard-to-diagnose zoonosis, it is important to pursuit an early diagnosis because the symptoms respond well to antibiotics or it might be resistant to treatment and may evolve to a chronic phase with both articular and neurological sequelae.

Artrite enteropática no Brasil: dados do registro brasileiro de espondiloartrites / Enteropathic arthritis in Brazil: data from the brazilian registry of spondyloarthritis

As doenças inflamatórias intestinais (doença de Crohn e retocolite ulcerativa) apresentam manifestações extraintestinais em um quarto dos pacientes, sendo a mais comum a artrite enteropática. MÉTODOS: Estudo prospectivo, observacional e multicêntrico, realizado com pacientes de 29 centros de referência participantes do Registro Brasileiro de Espondiloartrites (RBE), que se incorpora ao grupo RESPONDIA (Registro Ibero-americano de Espondiloartrites). Dados demográficos e clínicos de 1472 pacientes foram colhidos, e aplicaram-se questionários padronizados de avaliação de mobilidade axial, de qualidade de vida, de envolvimento entesítico, de atividade de doença e de capacidade funcional. Exames laboratoriais e radiográficos foram realizados. Objetivamos, neste presente artigo, comparar as características clínicas, epidemiológicas, genéticas, imagenológicas, de tratamento e prognóstico de enteroartríticos com os outros espondiloartríticos nesta grande coorte brasileira. RESULTADOS: Foram classificados como enteroartrite 3,2% dos pacientes, sendo que 2,5% tinham espondilite e 0,7%, artrite (predomínio periférico). O subgrupo de indivíduos com enteroartrite apresentava maior prevalência de mulheres (P < 0,001), menor incidência de dor axial inflamatória (P < 0,001) e de entesite (P = 0,004). O HLA-B27 foi menos frequente no grupo de enteroartríticos (P = 0,001), mesmo se considerado apenas aqueles com a forma axial pura. Houve menor prevalência de sacroiliíte radiológica (P = 0,009) e também menor escore radiográfico (BASRI) (P = 0,006) quando comparado aos pacientes com as demais espondiloartrites. Também fizeram mais uso de corticosteroides (P < 0,001) e sulfassalasina (P < 0,001) e menor uso de anti-inflamatórios não hormonais (P < 0,001) e metotrexato (P = 0,001). CONCLUSÃO: Foram encontradas diferenças entre as enteroartrites e as demais espondiloartrites, principalmente maior prevalência do sexo feminino, menor frequência do HLA-B27, associados a uma menor gravidade do acometimento axial.

Inflammatory bowel diseases (Crohn's disease and ulcerative rectocolitis) have extraintestinal manifestations 25% of the patients, with the most common one being the enteropathic arthritis. METHODS: Prospective, observational, multicenter study with patients from 29 reference centers participating in the Brazilian Registry of Spondyloarthritis (RBE), which incorporates the RESPONDIA (Ibero-American Registry of Spondyloarthritis) group. Demographic and clinical data were collected from 1472 patients and standardized questionnaires for the assessment of axial mobility, quality of life, enthesitic involvement, disease activity and functional capacity were applied. Laboratory and radiographic examinations were performed. The aim of this study is to compare the clinical, epidemiological, genetic, imaging, treatment and prognosis characteristics of patients with enteropathic arthritis with other types of spondyloarthritis in a large Brazilian cohort. RESULTS: A total of 3.2% of patients were classified as having enteroarthritis, 2.5% had spondylitis and 0.7%, arthritis (peripheral predominance). The subgroup of individuals with enteroarthritis had a higher prevalence in women (P < 0.001), lower incidence of inflammatory axial pain (P < 0.001) and enthesitis (P = 0.004). HLA-B27 was less frequent in the group with enteroarthritis (P = 0.001), even when considering only those with the pure axial form. There was a lower prevalence of radiographic sacroiliitis (P = 0.009) and lower radiographic score (BASRI) (P = 0.006) when compared to patients with other types of spondyloarthritis. They also used more corticosteroids (P < 0.001) and sulfasalazine (P < 0.001) and less non-steroidal anti-inflammatory drugs (P < 0.001) and methotrexate (P = 0.001). CONCLUSION: There were differences between patients with enteroarthritis and other types of spondyloarthritis, especially higher prevalence of females, lower frequency of HLA-B27, associated with less severe axial involvement.

Desigualdades socioeconômicas e demográficas como fatores de risco para a artrite autorreferida: estudo de base populacional em adultos no Sul do Brasil / Socioeconomic and demographic inequalities as risk factors for self-reported arthritis: a population-based study in southern Brazil

Estimar a prevalência de artrite ou reumatismo autorreferido e os fatores associados. Realizou-se um estudo transversal de base populacional em Florianópolis, Santa Catarina, Brasil, com 1.720 adultos entre 20 e 59 anos. A presença de artrite ou reumatismo autorreferido foi analisada por meio do modelo hierárquico de determinação no nível demográfico, socioeconômico, comportamental e uso de serviços de saúde. Utilizou-se análise de regressão logística para avaliar a associação entre as variáveis. A prevalência de artrite ou reumatismo autorreferido foi de 7,7% (IC95%: 6,4-8,9). A chance de artrite ou reumatismo autorreferido foi duas vezes maior entre as mulheres, maior entre aqueles com índice de massa corporal (IMC) > 30kg/m²,diretamente proporcional à idade e inversamente proporcional à escolaridade. A prevalência de artrite ou reumatismo autorreferido foi maior do que a estimativa nacional no ano de 2008. Essa realidade sugere a necessidade de um planejamento de políticas públicas voltado para esse agravo de saúde.

The study aimed to estimate prevalence of self-reported arthritis or rheumatism and associated factors. This was a cross-sectional population-based study in Florianopolis, Santa Catarina State, Brazil, with 1,720 adults ranging from 20 to 59 years of age. Presence of self-reported arthritis or rheumatism was analyzed with a hierarchical approach, considering demographic, socioeconomic, and behavioral variables and use of health services. Logistic regression was used to evaluate the association between the outcome and independent variables. Prevalence of self-reported arthritis or rheumatism was 7.7% (95%CI: 6.4-8.9). The odds of self-reported arthritis were twice as high in women, and increased self-reported arthritis was directly associated with BMI > 30kg/m² and increasing age and inversely proportional to schooling. Self-reported arthritis or rheumatism was higher in this sample than in Brazilian adults in general in 2008. The results suggest the need to plan public health policies to address this problem.

Systemic lupus Erythematosus and Neisseria gonorrhoea a case of the arthritis-dermatitis syndrome

Systemic lupus erythematosus (SLE) is a systemic disease characterized by arthritis among other protean manifestations. Occasionally lupus flares occur and is associated with increasing joint pains. In this state, complement is activated and leads to precipitation of immune complexes. Neisserial infections are cleared by complement and so in the presence of deficient complement, these infections will flourish. Disseminated gonococcal infection (DGI) occurs infrequently. A case of Neisseria gonorrhoea presenting as the arthritis-dermatitis syndrome which mimicked a lupus flare is presented and the appropriate literature reviewed.

Approach to Polyarthritis.

A child with polyarthritis is always a diagnostic challenge for the treating physician. By definition, polyarthritis, taken in context as a subgroup of juvenile idiopathic arthritis, is defined as inflammation of more than 4 joints on physical examination. Though the exact incidence and prevalence of polyarthritis in childhood is not known, it is not uncommon in pediatric practice. Polyarthritis can be a clinical manifestation of diverse disease processes and the differential diagnosis is understandably very broad. It can be caused directly by an infectious agent or indirectly by immune mechanisms, may be a component of a systemic disease process or may be idiopathic. The presentation can be acute or chronic. It can represent a benign self limiting illness requiring no specific treatment or may be a severely disabling condition with significant morbidity and, in some cases, even mortality.While in some situations it may be possible to arrive at a provisional clinical diagnosis right at the outset, in others the diagnosis gradually evolves over a period of time. As in most other arthritides, the most important aspects of the diagnosis are a thorough history and a detailed clinical examination. Relevant laboratory investigations can help in facilitating the diagnosis but can often also mislead the treating physician. Hereby we present a clinical approach to a child with polyarthritis.

Avaliação do paciente com artrite / Assessment of patients with arthritis

Artrites são manifestações clínicas de uma série de doenças. Sua classificação etiológica é muitas vezes difícil e depende de história clínica e exame físico cuidadosos. Artrite séptica e gota se apresentam mais comumente como monoartrite aguda e quadros reacionais são geralmente poliarticulares. A internação hospitalar é fator de risco para o desenvolvimento tanto de artrites reacionais quanto para crises de gota e artrite séptica. O diagnóstico precoce é muito importante a fim de iniciar o tratamento precocemente, alívio dos sintomas e preservação da funcionalidade articular. A punção do líquido sinoviale sua análise são de fundamental importância diagnóstica nos quadros de monoartrite aguda.

Arthritis are clinical manifestations of plenty of diseases. Its etiological classification is many timesdifficult and depends on careful clinical history and physical examination. Gout and skeptical arthritispresents commonly as acute monoarthritis and reactional arthritis are often polyarticular. Hospitalaradmission is a risk factor to the development of reactional arthritis, crisis of gout and septical arthritis.Early diagnosis is imperative to start early treatment, symptom relief and articular function preservation.Synovial fluid aspiration and its analysis are of critical diagnostic importance in cases of acute monoarthritis.

La artritis de la poliarteritis nodosa cutánea en niños se relaciona con la infección por estreptococos / Arthritis in cutaneous polyarteritis nodosa and its relationship with streptococcus

La poliarteritis nodosa cutánea (PANC) es una rara vasculitis que afecta los vasos de mediano calibre de la dermis, músculo, nervios periféricos y articulaciones, y que está frecuentemente relacionada con infección por estreptococo beta hemolítico del grupo A (EBHGA). Las características clínicas de la PANC posestreptocócica son fiebre, nódulos subcutáneos dolorosos y artritis. En nuestra cohorte de 12 pacientes, la artritis tuvo lugar con mayor frecuencia en las articulaciones grandes de miembros inferiores y tuvo una duración variable, desde días hasta meses. Este cuadro clínico, observado en niños de edad escolar, simula el de la fiebre reumática aguda, y por lo tanto puede llevar a la formulación de un diagnóstico erróneo. La presencia de nódulos con superficie rojiza, exquisitamente dolorosos, tumefacción subcutánea y muscular difusa y dolorosa, lesiones livedoides, así como la ausencia de compromiso cardíaco son orientadoras hacia el diagnóstico de PANC, que es confirmado ante el hallazgo de vasculitis de vasos medianos en la dermis. Si bien la respuesta a los esteroides sistémicos suele ser excelente, las recaídas son frecuentes y casi invariablemente asociadas a una nueva infección faríngea por EBHGA, por lo que es imperativo el uso profiláctico de penicilina a largo plazo.

Rotator Cuff Deficient Arthritis of the Glenohumeral Joint

Rotator cuff deficient arthritis of the glenohumeral joint, especially cuff tear arthropathy, has proved a challenging clinical entity for orthopaedic surgeons ever since Charles Neer originally detailed the problem in 1983. Understanding has improved regarding the pathophysiology and pathomechanics underlying cuff tear arthropathy. Surgical reconstruction options can lead to excellent outcomes for patients afflicted with these painful and functionally limited shoulders. Humeral hemiarthroplasty and reverse total shoulder arthroplasty have jumped to the forefront in the treatment of cuff tear arthropathy. As studies continue to look at the results of these procedures in cuff tear arthropathy, existing indications and treatment algorithms will be further refined. In this article the history and pathophysiology of cuff tear arthropathy are reviewed. Additionally, the clinical findings and results of surgical reconstruction are discussed.

Autoinflammatory syndromes: report on three cases / Síndromes auto-inflamatórias: relato de três casos

Context: Autoinflammatory syndromes are diseases manifested by recurrent episodes of fever and inflammation in multiple organs. There is no production of autoantibodies, but interleukins play an important role and acute-phase reactants show abnormalities. Our aim was to report on three cases of autoinflammatory syndromes that are considered to be rare entities. CASE REPORTS: The authors describe the clinical features of three patients whose diagnosis were the following: tumor necrosis factor receptor-associated periodic syndrome (TRAPS), chronic infantile neurological cutaneous articular (CINCA) syndrome and familial Mediterranean fever (FMF). All of the patients presented fever, joint or bone involvement and increased acute phase reactants. The genetic analysis confirmed the diagnoses of two patients. The great diversity of manifestations and the difficulties in genetic analyses make the diagnosing of these diseases a challenge.

Contexto: As síndromes auto-inflamatórias são doenças que se manifestam por surtos recorrentes de febre e inflamação em diversos órgãos. Não ocorre a formação de auto-anticorpos, as interleucinas representam um papel importante e as provas de fase aguda estão alteradas. O nosso objetivo foi relatar três casos de síndromes auto-inflamatórias consideradas como entidades raras. RELATO DE CASOS: Os autores descrevem as características clínicas de três pacientes que tiveram os seguintes diagnósticos: síndrome periódica associada ao receptor do fator de necrose tumoral α (TRAPS), síndrome articular cutânea neurológica e infantil crônica (CINCA) e febre familiar do Mediterrâneo (FFM). Todos os pacientes tiveram em comum a febre, o comprometimento articular ou ósseo e o aumento de provas de fase aguda. O estudo genético confirmou o diagnóstico em dois pacientes. A grande variedade de manifestações e a dificuldade nos estudos genéticos tornam o diagnóstico destas doenças um desafio.
