Intra-articular venous malformations of the knee are an uncommon cause of knee pain in children. Presenting symptoms of this rare subtype of venous malformation often include nonspecific pain and joint swelling, which may be episodic, and accompanied by limited range of motion. The signs and symptoms can mimic juvenile idiopathic arthritis (JIA). Timely diagnosis of…
Polyarteritis nodosa (PAN) is a systemic necrotizing vasculitis that typically affects medium-sized muscular arteries. The clinical subsets of PAN are idiopathic, generalized, secondary hepatitis B virus (HBV) associated and cutaneous PAN. These clinical subsets are important because of their therapeutic implications. Virtually any organ system can be affected in generalized PAN, but this vasculitis tends…
A 2021 study demonstrated the prevalence of COVID-19 breakthrough infections in vaccinated healthcare workers, underlining the need for booster shots for this at-risk population.
Spondyloarthropathy (SpA) can be difficult to diagnose, with rheumatologists sometimes relying on classification criteria designed for clinical trials. Research examines how the use of MRIs affects the finding of bone marrow edema and the diagnosis of axial SpA.
Research has revealed how the prevalence of anti-nuclear antibody (ANA) positivity has changed over the past 25 years, raising questions about the role of ANA in autoimmunity and disease.
A study was able to quantify the transference of tumor necrosis factor (TNF) inhibitors from mother to fetus during pregnancy. Overall, the researchers found low levels of transfer for the treatments studied.
Rheumatologists play a critical role in the reproductive health of their patients, but only half of rheumatologists currently ask their patients about reproductive health or family planning issues. A new guideline seeks to change that.
Treatment with denosumab for patients with RA and glucocorticoid-induced osteoporosis led to greater increases in bone mineral density of the lumbar spine and hips of patients than treatment with risedronate.
In March A&R, Remaeus et al. reported on the results of their study, which evaluated pregnancy outcomes in relation to anti-rheumatic treatment before and during pregnancy, as a proxy of disease severity in pregnant women with psoriatic arthritis (PsA), compared with those without PsA.
With both impressive sensitivity and specificity in capturing active large vessel vasculitis, a positron emission tomography (PET) scan is a potential tool for determining disease activity and predicting relapse in patients with large vessel vasculitis.
