This work presents a method for the automatic segmentation of metacarpus and phalange bones in ultrasound images of the second metacarpophalangeal joint (MCPJ) using Active Contours. The MCPJ is known to be the one of the first structures to be affected by rheumatic diseases like rheumatoid arthritis. The early detection and follow-up of this disease is important to prevent irreversible damage of the joints, which occurs continuously and faster if no treatment is used. To our knowledge, there is no automatic system to quantify the extension of the lesions resulting from rheumatic activity...

Our aim was to analyze the diagnostic performance of shear wave elastography (SWE) in the diagnosis of gouty arthritis (GA) and non-gouty arthritis (non-GA). Thirty-nine patients in the GA group and 55 patients in the non-GA group were included in the study. Based on the echo intensity of the joint lesions, the GA group was subdivided into hypo-echoic GA, slightly hyper-echoic GA and hyper-echoic GA subgroups. Quantitative SWE features were evaluated and receiver operating characteristic analysis was performed...

Contrast Enhanced Ultrasound (CEUS) is a sensitive imaging technique to assess tissue vascularity and it can be particularly useful in early detection and grading of arthritis. In a recent study we have shown that a Gamma-variate can accurately quantify synovial perfusion and it is flexible enough to describe many heterogeneous patterns. However, in some cases the heterogeneity of the kinetics can be such that even the Gamma model does not properly describe the curve, with a high number of outliers.

BACKGROUND: The Kocher criteria are established clinical parameters that predict hip septic arthritis (SA) with a 93% or greater positive-predictive value when 3 or 4 variables are present. The incidence of osteomyelitis (OM) in these patients has not been reported. The purpose of this study is to evaluate the incidence of OM in patients who have 3 or 4 positive Kocher criteria. METHODS: A total of 71 consecutive patients (mean age, 4.7 y) treated between January 2007 and July 2013 for suspected hip SA who had 3 or 4 positive Kocher criteria were retrospectively reviewed...

The arrival of new drugs and new therapeutic strategies allowed to reach sustained remission in an increasing number of patients with rheumatoid arthritis. The study of biologic disease-modifying anti-rheumatic drugs (bDMARDs) adaptation strategies is a need to optimize the benefit/risk balance and cost/effectiveness ratio of these molecules. Current recommendations such as EULAR 2016 propose tapering bDMARDs, especially when combined with a csDMARD, when the patient is in remission after stopping persistent glucocorticoids...

OBJECTIVE: Although a high risk of subclinical atherosclerosis has been reported in Systemic Lupus Erythematosus (SLE), it is not adequately compared with that observed in other rheumatic and non-rheumatic high-cardiovascular (CVD) risk diseases, such as Rheumatoid Arthritis (RA) and Diabetes Mellitus (DM). Our objective was to evaluate the relative risk (RR) of subclinical atherosclerosis in SLE, RA and DM patients compared to healthy controls, and examine potential associations with traditional and disease-related CVD risk factors in SLE...

BACKGROUND: Management of massive rotator cuff tears in shoulders without glenohumeral arthritis remains problematic for surgeons. Repairs of massive rotator cuff tears have failure rates of 20% to 94% at 1 to 2 years postoperatively as demonstrated with arthrography, ultrasound, and magnetic resonance imaging. Additionally, inconsistent outcomes have been reported with debridement alone of massive rotator cuff tears, and limitations have been seen with other current methods of operative intervention, including arthroplasty and tendon transfers...

Gout is an inflammatory arthritis characterized by the deposition of monosodium urate crystals in the synovial membrane, articular cartilage and periarticular tissues leading to inflammation. Men are more commonly affected, mainly after the 5th decade of life. Its incidence has been growing with the population aging. In the majority of the cases, the diagnosis is made by clinical criteria and synovial fluid analysis, in search for monosodium urate crystals. Nonetheless, gout may sometimes have atypical presentations, complicating the diagnosis...

BACKGROUND: Recent studies have demonstrated that there is an inverse relationship between lymphatic egress and inflammatory arthritis in affected joints. As a model, TNF-transgenic (TNF-Tg) mice develop advanced arthritis following draining lymph node collapse, and loss of lymphatic contractions downstream of inflamed joints. As it is unknown if these lymphatic deficits are reversible, we tested the hypothesis that anti-TNF therapy reduces advanced inflammatory-erosive arthritis, associated with restoration of lymphatic contractions, repair of damaged lymphatic vessels, and evidence of increased monocyte egress...

: Patients with chronic inflammatory arthritis experience an increased incidence of cardiovascular (CV) events. In addition to visualizing atherosclerotic plaques, ultrasound examinations (USs) of the carotid arteries permit the measurement of subclinical markers of atherosclerosis, such as intima-media thickness (cIMT) and carotid segmental distensibility (cDC). The aims of the study were to identify the determinants of atherosclerosis acceleration (plaques, cIMT and cDC) in a sample of patients suffering from chronic arthritis and to compare these patients with a control group of people with ≤1 traditional risk factor (TRF) for CV disease...

OBJECTIVES: Ultrasonography (US) has been demonstrated to improve assessment of synovitis and disease activity in rheumatoid arthritis (RA). However, the utility and feasibility of US in RA in clinical practice in real life is not known. We aimed to investigate: i) the indications for performing US in RA in daily practice; and ii) whether the number of scanned joints varies according to the purpose. METHODS: Consecutive patients who had a US scan either for diagnosis or follow-up for RA from 5 centres were recruited...
