We report a case of a 27-year-old man with pigmented villonodular synovitis of the hip joint with coincident osteonecrosis of the femoral head. According to our review of the English-language literature, no detailed report of osteonecrosis of the femoral head complicated with pigmented villonodular synovitis has been published. Preoperative X-ray images showed joint narrowing and severe multipl...

PURPOSE We assessed whether MRI measures of synovitis, osteitis and bone erosion were associated with patient-reported outcomes (PROs) in a longitudinal clinical trial setting among patients with rheumatoid arthritis (RA). METHODS This longitudinal cohort of 291 patients with RA was derived from the MRI substudy of the GO-BEFORE randomised controlled trial of golimumab among methotrexate-naïv...

INTRODUCTION The aim of this study was to identify and characterize subclinical synovitis in patients with rheumatoid arthritis (RA) in clinical remission using power Doppler ultrasound (PDUS) and serum levels of biomarkers of inflammation and/or angiogenesis. METHODS We selected patients with RA in clinical remission defined as a Disease activity score of 28 joints (DAS28)-erythrocyte sedime...

Pigmented villonodular synovitis is a benign proliferative disease involving the synovium. Pigmented villonodular synovitis is rare after replacement arthroplasty and has not been recognised and reported as a cause of failure of unicompartmental knee replacement in the literature.

BACKGROUND Qualitative differences in synovitis between the cartilage-pannus junction (CPJ) region and the adjoining suprapatellar pouch (SPP) have been reported in rheumatoid arthritis and the spondyloarthropathies. OBJECTIVE To determine if the distribution of synovitis is the same in osteoarthritis (OA) using sensitive measures of inflammation derived from dynamic, contrast enhanced magnet...

Synovial tissue can display an inflammatory response in the presence of OA. There is increasing interest to better understand the role of inflammation in OA, particularly with regard to those who require joint replacement. A systematic review of inflammatory synovitis in OA of literature databases was undertaken from their inception until October 14, 2014. Independent critical appraisal of each...

Methods Cross sectional study with prospective follow-up of 28 patients with JIA in remission. Inclusion criteria: oligoarticular or poliarticular subtypes, clinical/laboratory remission and age between 5-18 years. 12 healthy controls were evaluated at baseline. Clinical evaluation: physical examination, laboratory tests and ophthalmologic evaluation at baseline and every 6 months up to 24 mont...

INTRODUCTION The high incidence of transient synovitis in early childhood makes it the first suspected pathology in a limping child. Trauma, which has long been regarded as a causative factor for transient synovitis, may be underestimated in a non-cooperative toddler.After excluding most serious conditions, such as septic arthritis, a speculative diagnosis of transient synovitis can be made, an...

INTRODUCTION Pigmented villonodular synovitis is a rare disease of unknown etiology mostly affecting the knee and foot. Until now an association with autoimmune diseases has not been reported. CASE PRESENTATION The diagnosis of systemic lupus erythematosus was made in a 15-year-old Caucasian girl based on otherwise unexplained fatigue, arthralgia, tenosynovitis, leukopenia, low platelets and ...

OBJECTIVE Rheumatoid synovitis is characterized by an invasive and tissue-destructive infiltrate of lymphocytes, macrophages and synoviocytes. Matrix metalloproteinases (MMPs) and tissue inhibitors of metalloproteinases (TIMPs) produced by these cells are important in the remodelling of the articular tissues in rheumatoid arthritis (RA). The aim of this study was to explore whether the serum co...
