Introduction: The Accreditation Council for Graduate Medical Education and the American Board of Psychiatry and Neurology first developed milestones for the clinical neurophysiology (CNP) fellowship in 2015. The milestones provide a comprehensive evaluation of the fellow's development based on six domains of competency. Here, we describe the development of a new set of milestones for CNP fellowship with level 1 as the incoming level, level 4 as the goal for graduation, and level 5 as the aspirational level that may not be achieved. Methods: Committee members were nominated or volunteered to participate in the milestones update. Milestone development began with the creation of a shared mental model of the ideal skills and knowledge a graduating CNP fellow should attain. Results: The CNP committee met virtually 7 times for a total of 14 meeting hours. Nine Patient Care and five Medical Knowledge milestones evolved from the seven Patient Care and six Medical Knowledge milestones that were in the first iteration. The committee incorporated 11 “Harmonized Milestones” into the revision and a supplemental guide was created. Conclusions: The revised Accreditation Council for Graduate Medical Education milestones for CNP fellowship contain important updates that program directors should review against their curricula to identify any gaps in learning. Program leadership should take note of two new Patient Care milestones for telemedicine and intraoperative monitoring. Clinical neurophysiology fellowships are not designed to provide level 4 competency across all milestones. The revised milestones should be viewed within the context of an individual program's goals.

Abstract Introduction/Aims Intracellular congophilic inclusions within muscle fibers, although nonspecific, are one of the pathological hallmarks of sporadic inclusion body myositis (sIBM). Extracellular amyloid deposits in muscle, on the other hand, are the canonical findings of amyloid myopathies, which occur with or without systemic amyloidosis. Methods We reviewed the muscle biopsy database (1998–2020) to identify sIBM patients with extracellular amyloid deposits. Clinical and laboratory data were reviewed. Results We identified five sIBM patients (three clinicopathologically defined and two clinically defined) with extracellular amyloid deposits in muscle. Mean age at diagnosis was 74.8 y (range, 68–84 y). All patients had a typical sIBM pattern of weakness without associated sensory or autonomic symptoms. None had electrophysiological evidence of peripheral neuropathy. Only one patient had a monoclonal gammopathy (immunoglobulin M‐lambda, IgM‐λ) with normal bone marrow biopsy. This patient with monoclonal gammopathy and three other patients underwent abdominal fat pad aspirate and were negative for amyloid. Cardiac evaluation was unrevealing in the four patients tested. Three patients without monoclonal gammopathy had normal transthyretin gene sequencing and inconclusive mass spectrometry‐based analysis. The patient with monoclonal gammopathy died of pneumosepsis 5 y after diagnosis and autopsy revealed multi‐organ transthyretin amyloidosis. Discussion Detection of extracellular amyloid deposition in muscle should trigger an aggressive search for systemic amyloidosis independently from other associated myopathological abnormalities. Amyloid subtyping is crucial for early therapy and mortality prevention. An isolated monoclonal gammopathy should not halt a search for non‐hematological causes of systemic amyloidosis.
