Osteopontin (OPN) is an osteogenic marker protein. Osteoblast functions are affected by inflammatory cytokines and pathological conditions. OPN is highly expressed in bone legions such as rheumatoid arthritis. However, local regulatory effects of OPN on osteoblasts remain ambiguous. Here, we examined how OPN influences osteoblast responses to mechanical stress and growth factors. Expression of NO synthase 1 (Nos1) and Nos2 was increased by low intensity pulsed ultrasound (LIPUS) in MC3T3-E1 cells and primary osteoblasts...

Juvenile Idiopathic Arthritis is a heterogeneous condition and an important cause of acquired disability in children. Evidence supports early treatment to prevent future complications. This relies on prompt diagnosis, achieved by a high index of clinical suspicion and supportive evidence, including the detection of joint and or tendon inflammation. Ultrasound is a readily accessible, well tolerated, safe and accurate modality for assessing joints and the surrounding soft tissues. It can also be used to guide therapy into those joints and tendon sheaths, resistant to systemic treatments...

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...

Ultrasonography (US) has shown to be more sensitive than physical examination for diagnosis and assessment of rheumatoid arthritis (RA). It is also a useful approach for accurate monitoring and intensive treatment adjustment. However, there is limited information concerning the impact of US on therapeutic decision-making in routine daily practice. A single-center cross-sectional study in routine daily practice was conducted to determine the percentage of patients with rheumatoid arthritis (RA) in which treatment decision was modified on the basis of results of musculoskeletal ultrasonography...

Background Albuminuria is a marker for subclinical cardiovascular disease (CVD) in the general population. It is uncertain whether this association is present in patients with rheumatoid arthritis (RA), a population with increased atherosclerosis and CVD events. Methods Urine albumin from a spot morning collection was measured and the ratio of urine albumin:creatinine (uACR) calculated for RA and a population-based sample of demographically matched non-RA controls. Associations of elevated uACR (≥25mg/g for women and ≥17mg/g for men) with CVD risk factors and measures of atherosclerosis [coronary artery calcification (CAC) and ultrasound-determined maximal intima-media thickness (IMT) of the common (CCA) and internal (ICA) carotid arteries, and presence of focal plaque in the ICA] were compared cross-sectionally according to RA status...

This study aimed to assess infrared thermography (IRT) and ultrasonography (US) for detecting wrist arthritis in juvenile idiopathic arthritis (JIA) patients. Although IRT could help us detecting joint inflammation, IRT studies in JIA patients with wrist arthritis are still limited. Currently, no validated US criteria exist for detecting arthritis, and the most useful parameters between Gray-scale ultrasound (GSUS) or Power Doppler ultrasound (PDUS) remain unclear. Therefore, this study focused on detecting wrist arthritis in varying degrees using IRT and US compared with physical examination...
