Artifacts in brain magnetic resonance imaging due to metallic dental objects
Objective: Artifacts caused by metallic objects, such as dental crowns, dental implants and metallic orthodontic appliances, are a common problem in head and neck MRI. The aim of this retrospective study was to identify the main metal dental objects that produce artifacts on brain MRIs.Study design: Imaged metallic artifacts and their sources were identifi ed. Artifact image plane was rated on a score of 0 or 1 (0 - distinguishable for diagnosis and 1 - not distinguishable for diagnosis).Results: Seventy-eight percent of the artifacts appearing in images were caused by orthodontic appliances, followed by dental titanium implants (18%) and metallic crowns (4%).

American College of Rheumatology Provisional Criteria for Clinically Relevant Improvement in Children and Adolescents With Childhood-Onset Systemic Lupus Erythematosus
OBJECTIVE: To develop a Childhood Lupus Improvement Index (CHILI) as a tool to measure response to therapy in childhood-onset systemic lupus erythematosus (cSLE), with a focus on clinically relevant improvement (CRIc SLE ). METHODS: Pediatric nephrology and rheumatology subspecialists (n = 213) experienced in cSLE management were invited to define CRIc SLE and rate a total of 433 unique patient profiles for the presence/absence of CRIc SLE . Patient profiles included the following cSLE core response variables (CRVs): global assessment of patient well-being (patient-global), physician assessment of cSLE activity (MD-global), disease activity index score (here, we used the Systemic Lupus Eryt…
