INTRODUCTION In this study, we aimed to investigate ultrasonographic (US) changes suggestive of gouty arthritis in the hyaline cartilage, joints and tendons from asymptomatic individuals with hyperuricemia. METHODS We conducted a cross-sectional, controlled study including US examinations of the knees and first metatarsal-phalangeal joints (first MTPJs),(More)
OBJECTIVE The main aim of this study was to investigate the short-term efficacy of CS loco-regional treatment performed under US guidance in tenosynovitis of patients with chronic inflammatory arthritis. METHODS Thirty consecutive patients affected by chronic arthritis and with clinical suspicion of tenosynovitis were recruited to undergo US assessment.(More)
Ultrasound is a rapidly evolving technique that is gaining an increasing success in the assessment of psoriatic arthritis. Most of the studies have been aimed at investigating its ability in the assessment of joints, tendons, and entheses in psoriatic arthritis patients. Less attention has been paid to demonstrate the potential of ultrasound in the(More)
OBJECTIVE The objective of this study was to determine the prevalence and distribution of bone erosions detectable by US in patients with early RA (ERA) in comparison with long-standing RA (LSRA), other erosive diseases and healthy controls. METHODS Thirty patients with ERA and 80 patients with LSRA were consecutively recruited. Thirty patients with PsA,(More)
OBJECTIVE To compare, "in a real world," the performance of the most common composite activity indices in a cohort of PsA patients. METHODS A total of 171 PsA patients were involved. The following variables were evaluated: peripheral joint assessment, patient reported of pain, physician and patient assessments of disease activity, patient general health(More)
OBJECTIVE The objective of this study was to draw up a set of recommendations for the format and content of the musculoskeletal ultrasonography (MSUS) report in rheumatology. METHODS A panel of rheumatologists, members of the MSUS Study Group of the Italian Society of Rheumatology, met in order to identify the main discrepancies in the MSUS report. A set(More)
OBJECTIVE To evaluate the performance of a computerized-aided method (CaM) for quantification of interstitial lung disease (ILD) in patients with systemic sclerosis and to determine its correlation with the conventional visual reader-based score (CoVR) and the pulmonary function tests (PFTs). METHODS Seventy-nine patients were enrolled. All patients(More)
BACKGROUND Over the last decade, significant progresses have been achieved in the development and validation of new tools for the evaluation of disease activity in axial spondyloarthritis (SpA). Despite they play a key role in the assessment of these patients, the calculation scores are relatively complex and difficult to be quickly assessed in the busy(More)
OBJECTIVE To develop a preliminary power Doppler (PD) US composite score for global assessment of PsA patients. METHODS Sixteen PsA patients receiving anti-TNF-α therapy were enrolled. All patients were involved in multiple psoriatic targets, including joints, tendon, enthesis, skin and nail. The target with the highest PD signal, one for each target(More)
BACKGROUND Osteoarthritis (OA) is a multifactorial degenerative condition of the whole joint with a complex pathogenesis whose development and progression is significantly mediated by interactions between the joint cartilage and articular tissues, particularly, proinflammatory mediators and oxidative stress, which results in cartilage deterioration and(More)
