1. Introduction Within the past decade, musculoskeletal ultra-sound (US) has become an established imaging technique for the diagnosis and follow up of patients with rheumatic diseases. 1–5 This has been made possible through technological improvements, resulting in faster computers and higher frequency transducers. US is most commonly used in the(More)
OBJECTIVE To assess the interobserver reliability of the main periarticular and intra-articular ultrasonographic pathologies and to establish the principal disagreements on scanning technique and diagnostic criteria between a group of experts in musculoskeletal ultrasonography. METHODS The shoulder, wrist/hand, ankle/foot, or knee of 24 patients with(More)
OBJECTIVE To compare the clinical efficacy and safety of radiation synovectomy (RSO) with intraarticular (IA) yttrium-90 plus glucocorticoids (GCs) with the efficacy and safety of IA placebo yttrium plus GCs and to identify parameters that predict efficacy. METHODS The knees of 97 patients with persistent arthritis despite outpatient treatment with IA GCs(More)
Ultrasound (US) is a relatively new imaging modality in rheumatology that offers great potential as a diagnostic and management tool. In 2004, an OMERACT Ultrasound Special Interest Group was formed to address the metric qualities of US as a potential outcome measure. A preliminary systematic review highlighted the deficiencies in the literature,(More)
OBJECTIVE To assess the intra and interobserver reproducibility of musculoskeletal ultrasonography (US) among rheumatologists in detecting destructive and inflammatory shoulder abnormalities in patients with rheumatoid arthritis (RA) and to determine the overall agreement between US and MRI. METHODS A total of 14 observers examined 5 patients in 2 rounds(More)
OBJECTIVE Finger extensor tenosynovitis in rheumatoid arthritis (RA) may lead to partial and eventually to complete tendon tears. The aim of this study was to investigate the diagnostic value of sonography (SG) and/or magnetic resonance imaging (MRI) to visualize partial tendon tears. METHODS Twenty-one RA patients with finger extensor tenosynovitis for(More)
To compare the clinical efficacy of radiosynoviorthesis (RSO) with intra-articular radionuclide plus glucocorticoid (GC) injection (group A) with that of placebo plus GC injection (group B) for the treatment of persistent synovitis in joints of the upper extremity. At baseline and at 6 and 12 months after intra-articular injection, six clinical parameters(More)
OBJECTIVE To investigate the diagnostic value of sonography (SG) and magnetic resonance imaging (MRI) in the assessment of full-thickness rotator cuff tears (RCTs). METHODS Twenty-one consecutive, otherwise healthy patients with noninflammatory unilateral chronic (>3 months) shoulder complaints due to a possible full-thickness RCT were studied (9 women(More)
OBJECTIVES To evaluate differences in baseline characteristics between etanercept- and adalimumab-treated JIA patients and to reveal factors that influence the choice between these TNF inhibitors, which are considered equally effective in the recent ACR recommendations for JIA treatment. METHODS Biologic-naïve JIA patients with active arthritis who(More)
To investigate whether ultrasonographic joint assessment can predict the clinical response to intra-articular injection therapy of the knee. Patients with persistent gonarthritis intra-articularly received in a randomized double-blinded crossover fashion radiation synovectomy or a glucocorticoid injection, both followed by clinical bed rest.
