- ItemAcesso aberto (Open Access)Avaliação do ombro em pacientes portadores de espondilite anquilosante por meio de ultra-som(Sociedade Brasileira de Reumatologia, 2008-04-01) Yoshida Junior, Ciro; Kubota, Edson Shinji [UNIFESP]; Torres, Themis Mizerkowski [UNIFESP]; Ciconelli, Rozana Mesquita [UNIFESP]; Fernandes, Artur da Rocha Correa [UNIFESP]; Universidade Federal de São Paulo (UNIFESP)PURPOSE: To describe shoulder involvement and its prevalence with ultrasound in patients with ankylosing spondylitis and correlate the findings with age and duration of disease. METHODS: Ultrasound scans of both shoulders were performed in thirty five selected patients with clinical diagnosis of ankylosing spondylitis. Rotator cuff texture and thickness were evaluated as well as the biceps tendon, acromioclavicular joint, humeral head tuberosities, subacromial-subdeltoid bursa, and posterior glenohumeral joint. Besides the prevalence of shoulder involvement, information about presence of pain and duration of disease were registered. The data were compared with age and duration of disease using chi-square and Student's t tests. RESULTS: The prevalence of rotator cuff disease was 20%; with 10% of tendinosis/tendon calcification and 10% of partial/full thickness tears. The mean rotator cuff thickness was 5.8 mm. Irregularities of the humeral head tuberosities were present in 84.3% of shoulders and acromioclavicular irregularities were present in 54.3% of shoulders. CONCLUSION: There was no change in rotator cuff thickness related with duration of disease. Bony irregularities in humeral head tuberosities and acromioclavicular joint were the main finding associated with duration of disease. There was no relation between duration of disease and presence of tendinous disease.
- ItemAcesso aberto (Open Access)O papel da translucência nucal no rastreamento de cardiopatias congênitas(Sociedade Brasileira de Cardiologia - SBC, 2006-09-01) Bruns, Rafael Frederico [UNIFESP]; Moron, Antonio Fernandes [UNIFESP]; Murta, Carlos Geraldo Viana [UNIFESP]; Gonçalves, Luís Flávio De Andrade [UNIFESP]; Zamith, Marina Maccagnano [UNIFESP]; Universidade Federal de São Paulo (UNIFESP); Clínica Materno-Fetal; Vitória MedifetusOBJECTIVE: Assess the accuracy of the nuchal translucency (NT) measurement between 11 and 13 weeks and 6 days of gestation as a sonographic marker to screen for congenital heart defects (CHD). METHODS: Multicentric retrospective study, analyzing single pregnancies from euploid fetuses. NT measurement was performed in the first trimester, when fetuses had from 45 to 84 mm of crown-rump length (CRL), according to the criteria established by the Fetal Medicine Foundation. Cases were followed until 1 month after delivery to verify the presence of CHD. RESULTS: 3,664 pregnancies were analyzed and 20 newborns had CHD diagnosed until the first month of life (prevalence of 0.55%). The median NT of the fetuses with CHD was 1.70 mm and 1.60 mm for fetuses without CHD, however no significant difference was found (Mann-Whitney test, p > 0.05). The sensitivity of NT in detection of CHD varied from 15% to 20%, with a range of false positive probability from 86.4% to 97.9%, depending on the cut-off point used. However, the odds ratio was high, compared to the classic indications of echocardiography, ranging from 4.7 to 33.7 according to the cutt-off point. CONCLUSION: In spite of the low sensitivity of the test, enlarged NT is an important risk factor for CHD and should be used in prenatal screening for CHD.
- ItemAcesso aberto (Open Access)Ultra-sonografia na artrite reumatóide: aplicabilidade e perspectivas(Sociedade Brasileira de Reumatologia, 2008-02-01) Fernandes, Eloy de Ávila [UNIFESP]; Castro Junior, Moacir Ribeiro de [UNIFESP]; Mitraud, Sônia de Aguiar Vilela [UNIFESP]; Kubota, Edson Shinji [UNIFESP]; Fernandes, Artur da Rocha Correa [UNIFESP]; Universidade Federal de São Paulo (UNIFESP)This review discusses the usefulness of ultrasound in the early diagnosis of reumathoid arthritis, its utilization in these patients treatment and its utility in evaluation of the response to treatment. Reumathoid arthritis is a chronic disease that when it is not promptly diagnosed it can cause physical deformity and disability to work. The early introduction of disease modifying antirheumatic drugs (DMARDs), no matter traditional or newer (biologic agents), may modify the disease outcome. In order that , the diagnosis of RA must be made as soon as possible. Ultrasound makes possible to study the joints and can show signs of inflammatory activity, especially synovitis. Color Doppler and power Doppler can help differentiate between active inflammatory tissue (pannus) and inactive inflammatory tissues. Erosions, tenossynovitis, bursitis, cysts and effusions can also be found. This article demonstrates that methods to quantify de inflammatory activity on ultrasound must yet be established.
- ItemAcesso aberto (Open Access)O uso do ultra-som (US) na reumatologia(Sociedade Brasileira de Reumatologia, 2005-12-01) Azevedo, Ana Beatriz Cordeiro de [UNIFESP]; Martins, Emiliano Pontes [UNIFESP]; Holanda, Haroldo Tenório de [UNIFESP]; Mitraud, Sônia de Aguiar Vilela [UNIFESP]; Fernandes, Artur da Rocha Correa [UNIFESP]; Ciconelli, Rozana Mesquita [UNIFESP]; Universidade Federal de São Paulo (UNIFESP)In the past years, ultrasonographic studies achieved a solid position as an important method of imaging diagnosis in the evaluation of musculoskeletal diseases. Visualization of intra-articular structures and synovial vascular flow improved with the development of new ultrasound technologies, as better transducers, software and Doppler techniques. Ultrasound is being applied as an assistant diagnostic tool in the identification of soft tissue lesions and fluid collections, evaluation of articular structures compromised by rheumatic diseases and also as a guidance tool for invasive procedures in rheumatology, like joint aspiration and injection.
