ABSTRACT

Comunicamos el caso de un niño con sinovitis de cadera como manifestación inicial atípica de una infección por SARS-CoV-2. Varón de 7 años que consultó por dificultad en la marcha e impotencia funcional con dolor localizado en la cadera derecha. El diagnóstico presuntivo fue sinovitis transitoria de cadera, por lo que recibió tratamiento conservador. A los 12 días, continuaba con impotencia funcional y presentó decaimiento y fiebre. Ante la evolución atípica del cuadro, se decidió su internación para punción articular/drenaje. Se obtuvo un líquido articular claro de aspecto inflamatorio que no presentó desarrollo en los cultivos bacterianos. Durante la internación, se confirmó el resultado positivo de la reacción en cadena de la polimerasa para SARS-CoV-2. El paciente evolucionó favorablemente una vez resuelto el cuadro viral. En el último seguimiento, no tenía síntomas y el rango de movilidad era completo. La sinovitis transitoria de cadera puede ser una manifestación clínica inicial atípica de COVID-19. En el contexto de la pandemia, es indispensable sospechar una posible artropatía reactiva como consecuencia del virus, principalmente cuando la presentación es atípica, hay contactos familiares estrechos, fiebre u otros síntomas respiratorios asociados. Nivel de Evidencia: IV


We report the case of a pediatric patient with transient synovitis of the hip as an initial atypical manifestation of a COVID-19 infection. A 7-year-old boy presented with gait disturbance, limping, and pain in his right hip. After 12 days, the patient continued with functional limitations and had associated symptoms such as fatigue and fever. Because of the atypical course, he was admitted to the hospital for joint aspiration. Due to institutional protocols, the preoperative evaluation included a COVID-19 PCR test. The joint aspiration sample showed clear synovial fluid with inflammatory characteristics and negative bacterial culture. COVID-19 PCR test results came out positive during the patient's hospital stay. Clinical symptoms improved after the viral condition resolved. In the last follow-up, he was asymptomatic with a full hip range of motion. Transient synovitis of the hip could be an atypical initial symptom of a COVID-19 infection. Given the pandemic context of this disease, it is important to consider reactive arthritis as a consequence of this infection, especially in cases of atypical presentation, close family contact, fever, or other associated respiratory symptoms. Level of Evidence: IV

ABSTRACT

Introducción: La tuberculosis osteoarticular es una enfermedad inflamatoria crónica, muy rara con un cuadro clínico atípico y se presenta con una incidencia de 1-2 por ciento del total de los casos de tuberculosis. Objetivo: Exponer una forma de presentación poco frecuente de tuberculosis en Honduras Presentación del caso: Se trata de una niña de dos años con diagnóstico inicial de sinovitis en rodilla derecha de cinco meses de evolución y tratada con antibiótico y analgésico. Sin mejoría se presenta a emergencia con cambios inflamatorios. Se realiza rayos x de rodilla que muestran lesiones osteolíticas a nivel de rótula y cóndilo del fémur derecho. Baciloscopia de esputo y prueba de tuberculina negativas. Familiar de tercer grado positivo para tuberculosis hacía un año y medio. Por biopsia de tejido blando y óseo de rodilla derecha se establece el diagnóstico de artritis por Mycobacterium tuberculosis por estudio inmuno-histoquimico con tinción Ziehl Nielsen. Conclusiones: Es el primer informe de caso de tuberculosis osteoarticular en un paciente pediátrico descrito en Honduras. Por la larga evolución de la enfermedad, lo atípico de su clínica y su baja incidencia es difícil establecer el diagnóstico final. Fue imprescindible el estudio anatomopatológico por biopsia que permitiera esclarecer a los clínicos el diagnóstico e iniciar el tratamiento oportuno(AU)


Introduction: Osteoarticular tuberculosis is a chronic inflammatory disease, very rare, and with an atypical clinical picture and occurs with an incidence of 1-2 percent of all TB cases. Objective: Show a rare form of TB´s presentation in Honduras Case presentation: Two-year-old girl with an initial diagnosis of right knee synovitis of five months of evolution and treated with antibiotics and analgesics. Without improvement, she attends to emergencies service with inflammatory changes. Knee x-rays show osteolytic lesions at the kneecap level and the condyle of the right femur. Sputum bacilloscopy and negative tuberculin test were performed. She had a third-grade relative positive to tuberculosis a year and a half ago. A right knee soft tissue and bone biopsies confirm the diagnosis of arthritis by Mycobacterium tuberculosis by immuno-histochemical study with Ziehl Nielsen staining. Conclusions: It is the first osteoarticular TB case report in a pediatric patient described in Honduras. Because of the long evolution of the disease, the atypicalness of its clinic features and its low incidence, it is difficult to establish the final diagnosis. Anatomopathological study by biopsy was essential to clarify the diagnosis to clinicians and initiate timely treatment(AU)

ABSTRACT

ABSTRACT Introduction: The radiosynovectomy (RS) is one treatment option for recurrent hemarthrosis in patients with hemophilia (PWH). A prospective cohort study was designed to evaluate the effects of the RS on the synovial membrane volume in the ankles and knees of PWH and patient characteristics related to the RS outcome. Methods: In a one-year follow-up, 25 joints of 22 PWH who presented 3 bleeds or more in the same joint over the last 6 months (target joints) were subjected to the RS. Two groups were compared: those who retained target joints following the RS and those who did not (less than 3 bleeds/6 months after the RS). The groups were analyzed according to age, hemophilia type/severity, joint, body mass index (BMI), inhibitor and Hemophilia Joint Health Score 2.1 (HJHS). The magnetic resonance images (MRI) of six ankles and six knees were acquired prior to, and 6 months after, the RS. The synovial membrane volume and arthropathy MRI scale were accessed and volumes were compared and correlated with the Yttrium-90 dose injected. Results: Patients with a mean age of 12 years and a mean HJHS of 6.7 (p < 0.05) retained target joints after the RS. The inhibitor, joint, type/severity of disease and BMI showed no significant differences between groups. The synovial membrane volume had a significant reduction after the RS (p = 0.03), but no correlation with the Yttrium-90 dose. In proportion to the synovial membrane volume, doses injected to the ankles were larger than those injected to the knees. Conclusion: The synovial membrane volume is reduced after the RS, regardless of the effective 90Y dose.

ABSTRACT

O lipoma arborescente é uma causa incomum de lesão intra-articular que se apresenta como aumento de volume articular indolor, lentamente progressivo, que persiste por muitos anos e é acompanhado por derrames articulares intermitentes. O envolvimento de sítios extra-articulares é incomum, mas pode ocorrer em bainhas tendíneas e bursas. A ressonância magnética é o melhor exame para o diagnóstico, embora a biópsia sinovial possa ser necessária em alguns casos. Relatamos três casos com o objetivo de destacar o espectro clínico da doença, as características da imagem e a resposta ao tratamento imunossupressor.


Lipoma arborescens is an uncommon cause of intra-articular masses that presents as slowly progressive painless swelling of the joint, which persists for many years and is accompanied by intermittent effusions. Extra-articular site(s) involvement is unusual, but can occur in tendon sheaths and bursas. Magnetic resonance imaging is the best diagnostic exam, although synovial biopsy may be necessary. We report three cases in order to highlight the clinical spectrum and imaging features of the disease, so that early diagnosis and appropriate treatment can be given.

ABSTRACT

Surgical treatment is the main treatment for hemophilia arthritis, including synoviectomy, joint replacement and joint fusion. Synoviectomy is suitable for early hemophilia synovitis, and is divided into radiation, chemical, arthroscopy, and open operation. Radionuclides were recommended as the first choice due to its positive efficacy and less side effects, but exsit some problems such as scarcity of nuclides. Chemical synoviectomy is cheap and easy to operate, which is suitable for developing countriesm, while mutiple doses and pain after injection are main fault. Synoviectomy under arthroscope has a significant effect on the advanced lesion, but has a higher surgical risk. Open surgery with severe trauma and postoperative joint stiffness, is rarely performed. Joint replacement could effectively improve range of motion in advanced patients and is suitable for joints with high range of motion. Arthrodesis are effective in improving symptoms but lead to loss of range of motion and are suitable for joints with low range of motion. Operation for hemophilia arthritis has some problems, such as single operation, untimely diagnosis and treatment in early stage, and unsatisfactory curative effect in late stage. In addition, the treatment of hemophilia arthritis should focus on the early treatment, the formation of the whole process, the system of individual treatment concept.

ABSTRACT

RESUMEN El síndrome RS3PE (sinovitis simétrica seronegativa remitente con edema) fue descrito por McCarty (1985) como una forma benigna de artritis reumatoide de inicio en hombres mayores de 70 arios, con compromiso simétrico y asociada a edema de manos y pies. El enfoque de la poliartritis aguda en el adulto mayor debe incluir el síndrome RS3PE, en el que la pobre respuesta a esteroides y el compromiso multisistémico orientan hacia una naturaleza paraneoplásica, principalmente tumores sólidos (adenocarcinoma gástrico y pancreático), linfomas y leucemias. Se presenta el caso de un paciente con RS3PE como manifestación paraneoplásica de mesotelioma, una manifestación rara en este tipo de tumor.


A B S T R A C T Remitting seronegative symmetrical synovitis with pitting oedema (RS3PO) was described by McCarty (1985), as a benign form of rheumatoid arthritis that onset in men older than 70 years (80% of cases), with symmetrical and associated involvement of oedema of hands and feet. The approach of acute polyarthritis in the elderly should include the RS3PO syndrome, where poor steroid response and multisystem involvement oriented towards paraneoplastic nature, mainly with solid tumours (gastric and pancreatic adenocarcinoma), lymphomas and leukaemia. The case is presented of a patient with RS3PO as a paraneoplastic manifestation of mesothelioma, which is rare in this type of tumour.

ABSTRACT

OBJECTIVES: Radiographic manifestations of synovitis (e.g., erosions) can be observed only in the late stage of rheumatoid arthritis. Ultrasound is a noninvasive, cheap, and widely available technique that enables the evaluation of inflammatory changes in the peripheral joint. In the same way, dynamic contrast-enhanced magnetic resonance imaging (MRI) enables qualitative and quantitative measurements. The objectives of the study were to compare the sensitivity and accuracy of ultrasound in detecting subclinical synovitis and tenosynovitis with those of contrast-enhanced MRI. METHODS: The ultrasonography and contrast-enhanced MRI findings of the wrist, metacarpophalangeal, and proximal interphalangeal joints (n=450) of 75 patients with a history of joint pain and morning stiffness between 6 weeks and 2 years were reviewed. The benefits score was evaluated for each modality. RESULTS: The ultrasonic findings showed inflammation in 346 (77%) joints, while contrast-enhanced MRI found signs of early rheumatoid arthritis in 372 (83%) joints. The sensitivities of ultrasound and contrast-enhanced MRI were 0.795 and 0.855, respectively, and the accuracies were 0.769 and 0.823, respectively. Contrast-enhanced MRI had a likelihood of 0-0.83 and ultrasound had a likelihood of 0-0.77 for detecting synovitis and tenosynovitis at one time. The two imaging modalities were equally competitive for detecting synovitis and tenosynovitis (p=0.055). CONCLUSION: Ultrasound could be as sensitive and specific as contrast-enhanced MRI for the diagnosis of subclinical synovitis and tenosynovitis.

ABSTRACT

A síndrome de Lemierre caracteriza-se por uma rara entidade que gera tromboflebite da veia jugular interna e embolismo séptico em história da infecção recente da orofaringe, além de sinais radiológicos e isolamento de patógenos anaeróbicos, principalmente Fusobacterium necrophorum. Relatamos o caso de uma paciente do sexo feminino, 13 anos de idade, com histórico de carcinoma de nasofaringe associado ao vírus Epstein-Barr (estadiamento T4N2M0), submetida a procedimentos cirúrgicos e quimiorradioterapia. Iniciou com queixa de mialgia intensa, diplopia, lesões infectadas em membros e choque séptico. Por meio de exames de ultrassonografia cervical com Doppler colorido e tomografia computadorizada de pescoço com contraste endovenoso, foram identificados trombos intraluminais na veia jugular interna, além de trombos sépticos pulmonares, por meio da tomografia computadorizada de tórax. Posteriormente, ainda evoluiu com artrite piogênica coxofemoral esquerda. Foi isolada, por hemocultura, a bactéria Klebsiella pneumoniae Carpemenase, e o tratamento se deu pela associação entre vancomicina, amicacina, meropenem, metronidazol e anfotericina B. Conclui-se que, após o diagnóstico de SL e, embora com múltiplas complicações e diagnóstico tardio, a paciente encontra-se bem e assintomática, além do relato comprovar a dificuldade diagnóstica e de seu tratamento


Lemierre's syndrome is a rare condition that leads to thrombophlebitis of the internal jugular vein and septic embolism following recent oropharyngeal infection, being characterized by radiological signs and isolation of anaerobic pathogens, especially Fusobacterium necrophorum. We report the case of a 13-year-old female patient with history of nasopharyngeal carcinoma associated with Epstein-Barr virus (T4N2M0 staging), who underwent surgical procedures and chemoradiotherapy. Her initial complaint was severe myalgia, diplopia, infected limb injuries, and septic shock. Cervical color Doppler ultrasound and computed tomography scan of the neck with intravenous contrast showed intraluminal thrombi in the internal jugular vein, and chest computed tomography showed pulmonary septic thrombi. Subsequently, she progressed with left coxofemoral pyogenic arthritis. The bacterium Klebsiella pneumoniae Carpemenase was isolated in blood culture, and the patient was treated with the association of vancomycin, amikacin, meropenem, metronidazole, and amphotericin B. It is concluded that, despite the multiple complications and late diagnosis, the patient is well and asymptomatic after the diagnosis of Lemierre's syndrome; in addition, the report proves the difficulty of diagnosis and treatme

ABSTRACT

Resumen Introducción: Anormalidades ultrasonográficas se describen con cierta frecuencia en articulaciones de sujetos asintomáticos, las cuales generan incertidumbre en el contexto de evaluación y tratamiento de la enfermedad articular inflamatoria; a pesar de ello, en Colombia no existen estudios al respecto y la evidencia disponible es escasa, hecha en un bajo número de participantes y con transductores menores a 18 MHz en su gran mayoría. Objetivos: Describir los hallazgos ultrasonográficos articulares en manos y pies de un grupo de voluntarios asintomáticos, su asociación con las características sociodemográficas y la concordancia intra e interobservador de sus mediciones. Materiales y métodos: Estudio descriptivo y analítico en el que se incluyeron 182 voluntarios asintomáticos. Dos médicos con experiencia en ecografía musculoesquelética evaluaron el aspecto dorsal de 5.460 recesos articulares mediante la escala semicuantitativa de Szkudlarek y la utilización de un transductor lineal de 18 MHz. Resultados: La mediana de edad de los participantes fue de 42 arios, 60,4% de ellos mujeres. En 87% de los voluntarios se identificaron en total 232 hallazgos, el 68,1% correspondió a derrame articular, 29,3% a hipertrofia sinovial, 2,1% a erosiones y 0,4% a Doppler de poder. Los pies mostraron mayores hallazgos que las manos (70,7% vs. 29,3%). Las articulaciones en las que más se identificaron anormalidades fue la primera articulación metatarsofalángica (52%), la tercera metatarsofalángica (15%) y la radiocarpiana (9,5%). Se halló relación positiva entre el derrame articular y la hipertrofia sinovial con la edad, ocupación manual exclusiva y tiempo laboral mayor de 10 años. La concordancia intraobservador fue moderada (Kappa = 0,4591) y la interobservador fue leve (Kappa = 0,2155). Conclusiones: La ausencia de señal Doppler de poder, el no compromiso radioulnar distal, la ausencia de sinovitis acompañada de erosión y una mayor predominancia de alteraciones leves al nivel de las manos, sumado a la ausencia de hallazgos al nivel de la quinta articulación metatarsiana, constituyen hallazgos potencialmente específicos de sujetos asintomáticos que merecen ser confirmados como tal en futuros estudios.


Abstract Introduction: Ultrasound (US) abnormalities have often been described in the joints of asymptomatic subjects, which may lead to uncertainty in the evaluation and treatment of inflammatory joint disease. Despite this, the available evidence is scarce, with few participants, and in the vast majority with transducers less than 18Mhz. In Colombia there are currently no published studies about this topic. Objectives: To describe the ultrasound findings in hand and foot joints in asymptomatic volunteers, their association with sociodemographic characteristics, and intra- and inter-observer concordance of the measurements. Materials and methods: Descriptive and analytical study within 182 asymptomatic volunteers. Two physicians with musculoskeletal ultrasound experience evaluated the dorsal aspect of 5460 articular recesses using the semi-quantitative scale of Szkudlarek using a 18 MHz linear transducer. Results: The median age of the participants was 42 years, including 60.4% women. A total of 232 abnormal findings were identified in 87% of the volunteers, with 68.1% corresponding to joint effusion, 29.3% synovial hypertrophy, 2.1% erosions, and 0.4% positive power Doppler. The feet evaluation showed more findings than the hands (70.7 vs. 29.3%). The joints in which most abnormalities were identified were the first metatarsophalangeal joint (52%), third metatarsophalangeal joint (15%), and radiocarpal joint (9.5%). A positive association was found between joint effusion and synovial hypertrophy with age, exclusive manual activity, and occupation for more than ten years. The intra-observer concordance was moderate (Kappa = .4591) and the inter-observer was low (Kappa = .2155). Conclusions: The absence of power Doppler signal, the absence of abnormalities in distal radioulnar, the absence of synovitis accompanied by erosion, and a greater predominance of mild alterations in the hand joints, added to the absence of findings in the fifth metatarsal joint, can be potential specific findings of asymptomatic subjects and might be confirmed in future studies.

ABSTRACT

La radiosinoviortesis como tratamiento de la artropatía hemofílica, frecuentemente, ofrece excelentes resultados, al reducir grandemente el número de episodios de sangramiento y evitar daños ulteriores a las articulaciones. El Centro de Isótopos desarrolló el fosfato crómico coloidal marcado con Fósforo-32, producto listo para su empleo en pacientes hemofílicos. El objetivo de este trabajo fue evaluar la fuga extrarticular de este radiofármaco utilizado en la radiosinoviortesis en pacientes hemofílicos. Se determinó el porcentaje de fuga extrarticular del radiofármaco en 9 pacientes hemofílicos con sinovitis crónica, a los que se les realizó la radiosinoviortesis en la articulación de la rodilla. La radiactividad se midió, con un contador Geiger-Muller, sobre la rodilla tratada, en sus aspectos lateral, encima y medial; la rodilla contralateral; las cadenas linfáticas inguinales, de ambos lados, y el hígado. Los valores de fuga encontrados posteriormente a la inyección fueron 0,0046 por ciento a los 10 min; 0,0023 por ciento a las 24 horas; 0,1332 por ciento el día 7 y 4,0213 por ciento el día 30. Estos resultados coinciden con los valores comunicados por otros autores y con lo esperado de acuerdo a las características del producto, indican que se ejecutó el proceder adecuadamente y que los pacientes fueron seleccionados correctamente(AU)


Radiosynoviorthesis as a treatment for hemophilic arthropathy often offers excellent results, greatly reducing the number of bleeding episodes and avoiding further damage to the joints. The Isotope Center developed a product, Colloidal Chromic Phosphate labeled with Phosphorus-32, ready for use in hemophiliac patients. Our objective was to evaluate the joint leakage of this radiopharmaceutical use in radiosynoviorthesis in hemophilic patients. The percentage of radiopharmaceutical joint leakage was evaluated in 9 hemophilic patients with chronic synovitis, who underwent radiosynoviorthesis in the knee joint. The radioactivity was measured on the treated knee, in its lateral, above and medial aspects, the contralateral knee, the inguinal lymphatic chains of both sides and the liver, with a Geiger-Muller detector. The leakage values 8203;​found after the injection were 0.0046 percent at 10 minutes, 0.0023 percent at 24 hours, 0.1332 percent on day 7 and 4.0213 percent on day 30. These results are agreed with the values reported by other authors and with was expected according to the characteristics of the product, indicatate that the procedure was executed properly and that the patients were correctly selected(AU)

ABSTRACT

ABSTRACT Objective: To evaluate the inter-observer relationship of the "lumbar facet hypersignal classification" and the correlation with disc degeneration. Methods: Retrospective study of magnetic resonance images obtained from 24 (N=24) patients (9 males and 15 females), aged 35 to 79 years, mean age 48 years and 1 month. The images were reviewed by two spine surgeons, by five orthopedists in training in the specialty of spine surgery and one radiologist to evaluate and quantify the presence of hypersignal lumbar facet and the Pfirrmann Classification for disc degeneration. Results: One hundred and twenty lumbar discs and their joint facets were evaluated by the eight examiners, with data analyzed by the Cronbach test and the Spearman Correlation Analysis with statistically high results, confirming good inter-observer relation for the "Lumbar Facet Hypersignal Classification" and for the classification of Pfirrmann. There was no statistically significant relationship between facet arthrosis and disc degeneration. Conclusions: The results confirm that there is good inter-observer relationship for the classification of Facet Hypersignal and for the Classification of Pfirrmann. However, in spite of a positive relationship, a correlation between facet arthrosis and disc degeneration was not statistically significant. Level of Evidence III; Retrospective Comparative Study.


RESUMO Objetivo: Avaliar a relação inter observadores da "classificação de hipersinal facetária lombar" e a correlação com a degeneração discal. Métodos: Estudo retrospectivo de imagens de ressonância magnética obtidas de 24 (N= 24) pacientes (nove homens e 15 mulheres) com idade variando de 35 a 79 anos, com média de de 48 anos e um mês. As imagens foram revisadas por dois ortopedistas especialistas em cirurgia de coluna, por cinco ortopedistas em treinamento na especialidade de cirurgia de coluna e um radiologista, para avaliar e quantificar a presença de hipersinal facetário lombar e da Classificação de Pfirrmann para degeneração discal. Resultados: Foram avaliados e classificados 120 discos lombares e suas facetas articulares pelos oito examinadores, com dados analisados pelo Teste de Conbach e da Análise de Correlação de Spearman com resultados estatisticamente elevados, confirmando boa relação inter observadores para a "Classificação de Hipersinal Facetario Lombar" e para a classificação de Pfirrmann. Não foi observada relação estatisticamente significante entre artrose facetária e degeneração fiscal. Conclusão: Os resultados confirmam que existe boa relação inter observadores para a classificação de Hipersinal Facetário e para a Classificação de Pfirrmann. Porém, apesar de relação positiva, não se atingiu de maneira estatisticamente significante, correlação entre artrose facetaria e degeneração discal. Nível de Evidência III; Estudo Restrospectivo Comparativo.


RESUMEN Objetivo: Evaluar la relación inter-observadores de la "clasificación de hiperseñal facetaria lumbar" y la correlación con la degeneración de disco. Métodos: Estudio retrospectivo de imágenes de resonancia magnética obtenidas de 24 (N = 24) pacientes (9 hombres y 15 mujeres), con edad variando de 35 a 79 años, con promedio de 48 años y 1 mes. Las imágenes fueron revisadas por dos ortopedistas especialistas en cirugía de columna, por cinco ortopedistas en entrenamiento en la especialidad de cirugía de columna y un radiólogo para evaluar y cuantificar la presencia de hiperseñal facetaria lumbar y la Clasificación de Pfirrmann para degeneración de disco. Resultados: Fueron evaluados y clasificados 120 discos lumbares y sus facetas articulares por los ocho examinadores, con datos analizados por el Test de Cronbach y del Análisis de Correlación de Spearman con resultados estadísticamente elevados, confirmando buena relación inter-observadores para la "Clasificación de Hiperseñal Facetaria Lumbar" y para la clasificación de Pfirrmann. No se observó relación estadísticamente significativa entre artrosis facetaria y degeneración de disco. Conclusiones: Los resultados confirman que existe una buena relación inter-observadores para la clasificación de Hiperseñal Facetaria y para la Clasificación de Pfirrmann. Sin embargo, a pesar de una relación positiva, la correlación entre la artrosis facetaria y la degeneración de disco no fue estadísticamente significativa. Nivel de Evidencia III; Estudio Retrospectivo Comparativo.

ABSTRACT

RESUMEN La proliferación del tejido sinovial, que es llamada pannus, se ha considerado como una manifestación tardía, inactiva e irreversible de la artritis reumatoide (AR), contrario a lo que históricamente se ha estudiado. Se realizó una búsqueda de la literatura para realizar una revisión narrativa e histórica respecto al surgimiento del término pannus y su papel en la artritis reumatoide. Estudios de microscopia de luz han mostrado el carácter destructivo de este tejido con hallazgos característicos de la AR, corroborados con microscopia electrónica arios más tarde. Estos hallazgos llevaron a caracterizar el componente celular del pannus con gran número de células inmunológicas y de líneas celulares específicas con propiedades especiales como los sinoviocitos similares a fibroblastos. Este componente celular es el origen de una gran cantidad de citoquinas y proteinasas que perpetúan y causan el daño óseo y del cartílago. Este componente inflamatorio ha sido evidente también con el desarrollo de técnicas de imágenes, como la resonancia magnética y la ultrasonografía, que muestran un papel activo del tejido sinovial engrosado, junto a la hipervascularización en el daño articular y la reversibilidad de estos cambios tras el tratamiento. Las evidencias contempladas permiten concluir que el pannus como evidencia histológica (más que clínica) se refiere a la proliferación del tejido sinovial e incluye un gran componente celular activo que genera y perpetúa la inflamación y, por tanto, la enfermedad.


ABSTRACT Pannus refers to synovial tissue proliferation, and has been considered a late, inactive and irreversible manifestation of rheumatoid arthritis (RA), contrary to historical findings. A literature search was performed on terminology about pannus and its historical role in the pathophysiology of RA. Light microscopy studies have shown the destructive impact of pannus tissue with very specific abnormalities, corroborated a year later with electronic microscopy. Some of these findings are the isolation of the immunological cells inside the tissue, especially one cell line with particular capacities, called synoviocytes similar to fibroblasts. This cellular component is the source a large quantity of cytokines and proteinases that perpetuate and cause bone and cartilage damage. Inflammation has been seen in many image techniques, such as magnetic resonance and ultrasound. These show the role of tissue widening and hyper-vascularization in tissue damage, and some reversibility after treatment of RA. With the evidence presented it is possible to conclude that pannus refers to a histological (more than clinical) term for synovial hypertrophy, and includes a large component of cell activity that generates and perpetuates inflammation and thus the disease.

ABSTRACT

Background: In patients with hemophilia, radionuclide synoviorthesis, or the intra-articular injection of a radionuclide to decrease the synovial hypertrophy tissue, aims to decrease or avoid hemarthrosis. Aim: To evaluate the effectiveness of radionuclide synoviorthesis in hemophilia. Material and Methods: Observational retrospective study of the evolution of 107 male patients aged 3 to 54 years who were subjected to radionuclide synoviorthesis between 2007 and 2015. Results: Of 164 treated joints, in 65% treatment was successful, (defined as zero to two hemarthroses and absence of synovitis during the follow up period), in 17% it was partially successful (defined as two or less hemarthroses, but persistence of the synovitis) and failed in 18% of the procedures. No important complications were recorded. Conclusions: Radionuclide synoviorthesis has an overall 82% success rate, is minimally invasive, can be used at any age and is inexpensive We recommend its implementation in Chilean hemophilia treatment centers.

ABSTRACT

Abstract Synovial chondromatosis is a rare condition characterized by benign chondrogenic metaplasia of extra-articular synovial tissue. It usually affects a single tendon sheath of the hand or foot. This report describes a rare case with extensive synovial chondromatosis affecting all flexor tendons in the tarsal tunnel, its radiological features, surgical treatment, and clinical outcome. The authors present a unique case of extensive synovial chondromatosis in a 48-year-old male involving the tendon sheaths of the flexor hallucis longus, flexor digitorum longus, and posterior tibialis tendons, at the level of the tarsal tunnel, with extension into the plantar aspect of the foot. The patient initially presentedwith symptoms of tarsal tunnel compression and was found to have a 4-cm mass in the posteromedial aspect of the ankle. The presumptive diagnosis of synovial chondromatosiswasmadebased on radiographic and magnetic resonance imaging evidence. The patient underwent surgical resection of the tumor, aswell as tarsal tunnel releaseandgastrocnemius recession. The diagnosiswas confirmed postoperatively by surgical histopathology. The postoperative course of the patient was uncomplicated and his tarsal tunnel symptoms resolved. This represents a case of extensive synovial chondromatosis involving all flexor tendons in the tarsal tunnel that was correctly diagnosed by clinical and imaging findings, which required early surgical resection to avoid long-term neurovascular complications.


Resumo A condromatose sinovial é uma condição rara caracterizada por metaplasia condrogênica benigna do tecido sinovial extra-articular, que geralmente afeta uma única bainha tendínea da mão ou do pé. O objetivo é relatar o caso raro de um paciente com diagnóstico de condromatose sinovial extensa afetando todos os tendões flexores na topografia do túnel do tarso, suas características radiológicas, tratamento cirúrgico e desfecho clínico. Os autores apresentam um caso único de condromatose sinovial extensa em um homem de 48 anos envolvendo as bainhas dos tendões flexor longo do hálux, flexor longo dos dedos e tibial posterior, na topografia do túnel do tarso, com extensão para a região plantar do retropé. O sintoma inicial foi de compressão neurovascular (síndrome do túnel do tarso). A suspeita diagnóstica foi condromatose sinovial com base em evidências radiográficas e de ressonância magnética. O paciente foi submetido a ressecção cirúrgica do tumor, bem como a liberação do túnel tarsal e alongamento do tendão dos gastrocnêmios. O diagnóstico foi confirmado por exame histopatológico do espécime colhido no período intraoperatório. A evolução pósoperatória do paciente ocorreu sem complicações e os sintomas da síndrome do túnel do tarso cessaram. Os autores relatam um caso de condromatose sinovial extensa envolvendo todos os tendões flexores do túnel do tarso, corretamente diagnosticado por achados clínicos e radiológicos e que necessitou de ressecção cirúrgica precoce para evitar complicações neurovasculares em longo prazo.

ABSTRACT

This study aimed to investigate the correlation of ultrasonography (US) of synovitis with disease activity and clinical response to etanercept (ETN) in juvenile idiopathic arthritis (JIA) patients. Eighty-two JIA patients who underwent ETN treatment for 24 weeks were consecutively enrolled. US evaluations of 28 joints (shoulder, elbow, wrist, metacarpophalangeal, and proximal interphalangeal of hands and knee) at baseline were performed using grey-scale US and power doppler (PD) US, and US synovitis was defined as grey-scale abnormalities or PD abnormalities. Clinical response was assessed according to the ACRpedi 50 response criteria. In total, 2296 joints were scanned and 608 (26.5%) joints presented US synovitis, which was numerically higher than clinical synovitis (513 (22.3%)). The mean number of joints showing synovitis on US was 7.42±3.35, which was also numerically higher than that of clinical synovitis (6.26±2.70). The number of joints showing synovitis on US was positively correlated with C-reactive protein, erythrocyte sedimentation rate, number of joints with active disease, number of joints with limited range of motion, physician's global assessment of disease activity, parent/patient global assessment of overall well-being, and childhood health assessment questionnaire score. Most interestingly, the baseline number of joints showing synovitis on US was increased in ACRpedi 50 response JIA patients compared to non-response JIA patients, and it serves as an independent predictive factor for higher clinical response to ETN treatment. In conclusion, US is a more sensitive test to evaluate subclinical synovitis and disease activity in JIA patients, and US synovitis might serve as a marker for predicting increased clinical response rate to ETN treatment.

ABSTRACT

STUDY DESIGN: Experimental human study. PURPOSE: To determine whether angiopoietin-like protein 2 (ANGPTL2) is highly expressed in the hyperplastic facet joint (FJ) synovium and whether it activates interleukin-6 (IL-6) secretion in FJ synoviocytes. OVERVIEW OF LITERATURE: Mechanical stress-induced synovitis is partially, but significantly, responsible for degenerative and subsequently osteoarthritic changes in the FJ tissues in patients with lumbar spinal stenosis (LSS). However, the underlying molecular mechanism remains unclear. IL-6 is highly expressed in degenerative FJ synovial tissue and is responsible for local chronic inflammation. ANGPTL2, an inflammatory and mechanically induced mediator, promotes the expression of IL-6 in many cells. METHODS: FJ tissues were harvested from five patients who had undergone lumbar surgery. Immunohistochemistry for ANGPTL2, IL-6, and cell markers was performed in the FJ tissue samples. After cultured synoviocytes from the FJ tissues were subjected to mechanical stress, ANGPTL2 expression and secretion were measured quantitatively using real-time quantitative reverse-transcription–polymerase chain reaction and enzyme-linked immunosorbent assay (ELISA), respectively. Following ANGPTL2 administration in the FJ synoviocytes, anti-nuclear factor-κB (NF-κB) activation was investigated using immunocytochemistry, and IL-6 expression and secretion were assayed quantitatively with or without NF-κB inhibitor. Moreover, we assessed whether ANGPTL2-induced IL-6 modulates leucocyte recruitment in the degenerative process by focusing on the monocyte chemoattractant protein-1 (MCP-1) expression. RESULTS: ANGPTL2 and IL-6 were highly expressed in the hyperplastic FJ synovium samples. ANGPTL2 was co-expressed in both, fibroblast-like and macrophage-like synoviocytes. Further, the expression and secretion of ANGPTL2 in the FJ synoviocytes increased in response to stimulation by mechanical stretching. ANGPTL2 protein promoted the nuclear translocation of NF-κB and induced IL-6 expression and secretion in the FJ synoviocytes. This effect was reversed following treatment with NF-κB inhibitor. Furthermore, ANGPTL2-induced IL-6 upregulated the MCP-1 expression in the FJ synoviocytes. CONCLUSIONS: Mechanical stress-induced ANGPTL2 promotes chronic inflammation in the FJ synovium by activating IL-6 secretion, leading to FJ degeneration and subsequent LSS.

ABSTRACT

The intra-articular use of hyaluronic acid (HA) for the treatment of synovitis and osteoarthritis is still controversial. As a consequence, corticosteroids remain the most frequently employed therapeutic agents, despite their potential systemic and local deleterious effects. This study examined the anti-inflammatory, antioxidant, and chondroprotective activities of low and high molecular weight hyaluronic acid (LMW-HA and HMW-HA) on lipopolysaccharide (LPS)-induced synovitis in horses compared to triamcinolone acetonide (TA). LPS was injected in the metacarpophalangeal joints, which were treated intra-articularly with either TA (as control) or LMW-HA or HMW-HA. Joint clinical evaluation and synovial fluid (SF) analysis were performed at 0, 8, 24, and 48 h. The white blood cell counts (WBC), prostaglandin E2 (PGE2), interleukin (IL)-1, IL-6, IL-10, tumor necrosis factor-α, chondroitin sulfate (CS) and HA concentrations, oxidative burst, and HA molecular weights were measured. TA reduced the lameness, swelling, and PGE2 release but increased the SF CS concentrations enormously at 24h and 48h, and decreased the SF HA modal molecular weight. These results indicate the breakdown of articular cartilage aggrecan and SF HA. In contrast, LMW-HA and HMW-HA were less effective in reducing the inflammation symptoms, but preserved the joints because only a modest increase in CS occurred at 24 h, decreasing at 48 h, and the SF HA was maintained. The HA-treatment also had anti-inflammatory actions, and LMW-HA was the most effective in reducing the release of cytokine. In summary, the HA treatment inhibited efficiently the digestion of cartilage proteoglycans and SF HA breakdown.
