Rikkosan's Short-Term Analgesic Effect on Burning Mouth Syndrome: A Single-Arm Cohort Study.

Burning mouth syndrome (BMS) is a chronic oral pain disorder. There is a theory that BMS is a form of nociplastic pain. A standard treatment for BMS has not yet been established.

Cluster Analysis Using Anti-Aminoacyl-tRNA Synthetases and SS-A/Ro52 antibodies in Patients With Polymyositis/Dermatomyositis.

Objective: Although several autoantibodies have been identified for polymyositis/dermatomyositis (PM/DM) diagnosis, the clinical impact of these antibodies is yet to be elucidated.

Methods: Patients with PM/DM at Okayama University Hospital from 2012 to 2016 were historically enrolled, and antibody profiles were analyzed using line immunoassay. Hierarchical cluster analysis was performed based on serological analysis of anti-aminoacyl-tRNA synthetase (ARS) antibodies, including anti-Jo-1, PL-7, PL-12, EJ, OJ, and SS-A/Ro-52 antibodies.
