Prevalence of Neuropsychiatric Lupus in Psychosis Patients Who Have Tested Positive for Antinuclear Antibodies.

Objective: Psychosis is a rare manifestation of neuropsychiatric systemic lupus erythematosus (NPSLE). Current guidelines do not make a recommendation regarding the use of antinuclear antibody (ANA) testing in the assessment of patients with psychosis. The present study was undertaken to determine the prevalence of NPSLE in patients with psychosis who were positive for ANAs.

Shear-wave elastographic ultrasound of metacarpophalangeal synovium in rheumatoid arthritis - A pilot study.

Introduction: Shear-wave elastographic ultrasound (SW-EUS) assesses the stiffness of human tissues. It is used in liver, thyroid and breast imaging but has not been studied in synovium. Soft tissues have a slower shear-wave velocity (SWV) than stiff tissues.
