Ultrasonographic evaluation of femoral cartilage thickness in patients with psoriatic arthritis.

Background: Psoriatic arthritis (PsA) is a common form of arthritis that may vary from asymmetric oligoarthritis to symmetric polyarthritis and spondyloarthritis.

Objectives: To evaluate femoral cartilage thickness using ultrasonography in patients with PsA.

Methods: Thirty-three patients (24 female, 9 male) with a diagnosis of PsA and 31 age-, sex- and body mass index-similar healthy subjects were enrolled in this study.

Education and Visual Information Improves Effectiveness of Ultrasound-Guided Local Injections on Shoulder Pain and Associated Anxiety Level: A Randomized Controlled Study.

Objective: Local injections are widely used in patients with a painful shoulder. The aim of this study was to evaluate the possible impact of patients' visual information on the effectiveness of ultrasound (US)-guided local injections on anxiety levels and shoulder pain.

Design: A total of 151 patients, scheduled for local injection owing to shoulder pain, were randomly assigned into two groups in a consecutive order.
