Feels so good to be back to #Neurology. Today I had the pleasure to give #Neurologymorningreport on Necrotizing Autoimmune Myopathy #NAM. #MedTwitter follow below a few pearls I shared with the team @ErsidaBuraniqi@nzalewski2. THREAD. #NAM is an autoimmune myopathy characterized by severe proximal weakness, myofiber necrosis with minimal or no inflammatory infiltrates on muscle biopsy, and infrequent extra-muscular involvement.
