Background: It has been suggested that synovitis causes joint pain. On non-contrast-enhanced MRIs synovial thickening cannot be assessed and on these images synovitis has been inconsistently associated with pain. Objective: To assess synovial thickening in relation to knee pain severity among subjects in the Multicenter Osteoarthritis Study (MOST) using contrast-enhanced (CE) MRI. Methods: MOST is a cohort study of people who have, or are at high risk of, knee osteoarthritis (OA). An unselected subset of 535 participants who volunteered underwent CE 1.5 T MRI of one knee. Synovitis was scored in six compartments and a summary score was created. Knee pain severity was assessed using the maximum item score on the Western Ontario and McMaster Osteoarthritis Index (WOMAC) pain scale. The association between synovitis and pain severity was examined using a logistic regression model adjusting for age, sex, body mass index (BMI), MRI bone marrow lesions and effusions in the whole sample and in a subgroup without radiographic OA. Results: 454 of the 535 subjects undergoing CE MRI had complete data on synovitis and WOMAC pain. Mean age was 59 years, mean BMI 30 and 48% were women. In knees with moderate pain, 80% had synovitis. For knee pain, synovitis conferred a 9.2-fold increased odds compared with those without synovitis. In knees without radiographic OA (n=329), there was also an association of synovitis with an increased prevalence of pain. Conclusion: Synovitis has a strong relation with knee pain severity, an association detected more clearly with CE MRI than suggested by previous studies using non-CE MRI measures of synovitis.

Expert Opinion on Emerging Drugs | Year: 2013

Introduction: Only non-steroidal anti-inflammatories (NSAIDs) and TNF inhibitors (TNFi) are effective in ankylosing spondylitis (AS). However, not all patients successfully respond to these drugs and a subset may have contraindications to their use. Areas covered: In the last decade, an earlier diagnosis of AS has been achieved due to the increasing availability of MRI. This has led to prompt treatment initiation with improved outcomes. NSAIDs and TNFi are the current treatments for AS which lead to sustained clinical responses in the long term. Recent studies have shown other potential biomarkers in AS, such as the IL-17/IL-23 axis. This has translated into the development of new drugs which interfere with these pathways, such as apremilast and secukinumab, which have shown efficacy in early clinical trials. Expert opinion: AS carries considerable short- and long-term disabilities. Anti-TNF-α therapies reduce pain, improve function and decrease inflammation as seen by MRI. New treatment options are being developed which may prove efficacious on those patients not responding to anti-TNF. The ultimate research goal should focus on treatments to prevent and stop new bone formation. © 2013 Informa UK, Ltd. Source

During the past decade, there has been an increased description of Churg Strauss syndrome (CSS) characterized by vascular occlusions possibly linked to the thrombogenic potential of the eosinophil that is poorly appreciated. The purpose of this overview is 3-fold: the first to evaluate the available prevalence of thrombosis in Churg Strauss series, the second to demonstrate that any vascular district may be affected, and the third to describe the pathogenesis of thrombosis in CSS. A Pubmed, EMBASE, and Google search of CSS series from 1951 to date revealed a prevalence of arterial occlusion ranging between 3.1% and 18.7% and a prevalence of venous occlusion between 5.8% and 30%, whereas a specific survey for venous thromboembolism in CSS yielded a prevalence of 8.1%. Eosinophils store and release tissue factor as well as other cationic proteins: the former initiates coagulation while the latter inhibits natural anticoagulant activity and activate platelets eventually culminating in excessive thrombin generation and clot formation. In addition, antineutrophil cytoplasmic antibodies may shift the endothelial lining to proadhesive and prothrombotic surface. It is hoped that the review will represent a basis to foster novel research on this topic. © The Author(s) 2010. Source

Background Plaque psoriasis has a relatively high prevalence in adolescence, resulting in a significant impact on quality of life, including social interactions. Objectives The primary objective was to assess the safety of once-daily application of fixed-combination calcipotriol plus betamethasone dipropionate gel in adolescent scalp psoriasis. Assessment of efficacy was a secondary objective. Methods This phase II, multicentre, single-arm, open-label, 8-week trial included patients aged 12-17 years with moderate-to-very severe scalp psoriasis according to Investigator's Global Assessment (IGA) (≥ 10% of the scalp area affected). Results Seventy-eight patients received treatment. Twenty-seven patients (35%) reported a total of 64 adverse events (AEs); most were mild (33/64) or moderate (22/64) in severity and there were no serious AEs. No cases of hypercalcaemia were reported, and the mean changes from baseline to end of treatment in albumin-corrected serum calcium (0·00 mmol L-1), 24-h urinary calcium excretion (-0·03 mmol per 24 h) and urinary calcium-to-creatinine ratio (-0·12 mmol g-1) were not considered clinically relevant. At the end of treatment 66 patients (85%) were clear or almost clear according to IGA. There was an 80% improvement in mean Total Sign Score from baseline to end of treatment. In total, at the end of treatment, 87% of patients rated their scalp psoriasis as clear or very mild, and 75 (96%) had no or mild pruritus compared with 14 (18%) at baseline. Conclusions Once-daily calcipotriol plus betamethasone dipropionate gel is well tolerated and efficacious for scalp psoriasis in adolescents. What's already known about this topic? Calcipotriol plus betamethasone dipropionate gel is a well-tolerated and efficacious treatment for scalp and body psoriasis in adults. Psoriasis can present during childhood or adolescence and may negatively impact quality of life. What does this study add? Calcipotriol plus betamethasone dipropionate gel is well tolerated and shows efficacy for treatment of scalp psoriasis in an adolescent population. © 2014 The Authors.

Groin pain has a wide differential diagnosis, and its aetiology may be multifactorial. Common causes include hip joint pathology, sports hernia and snapping psoas, but rarer causes such as stress fracture, spinal pathology and intra-pelvic causes must be considered. Investigation is specific to the diagnosis postulated through a carefully taken history and examination. Femoroacetabular impingement is common and increasingly managed with hip arthroscopy, good short term results being reported. © 2012. Source
