Cardiac iodine-123-labeled-metaiodobenzylguanidine uptake is reduced in early-stage Parkinson's disease, suggesting sympathetic nerve degeneration. The scintigraphic findings in patients with Parkinson's disease with different clinical features have, however, not been established. Iodine-123-labeled-metaiodobenzylguanidine myocardial scintigraphy was(More)
OBJECTIVE To show cancer association is a risk factor other than statin exposure for anti-3-hydroxy-3-methylglutaryl coenzyme A reductase autoantibody-positive (anti-HMGCR Ab+) myopathy. METHODS We analyzed the clinical features and courses of 33 patients (23 female and 10 male) with anti-HMGCR Ab+ myopathy among 621 consecutive patients with idiopathic(More)
BACKGROUND The morphometric analysis of myelinated nerve fibers of peripheral nerves in cross-sectional optical microscopic images is valuable. Several automated methods for nerve fiber identification and segmentation have been reported. This paper presents a new method that uses a deep learning model of a convolutional neural network (CNN). We tested it(More)
OBJECTIVE To determine the clinical features of myositis patients with the histopathologic finding of CD8-positive T cells invading non-necrotic muscle fibers expressing major histocompatibility complex class 1 (CD8-MHC-1 complex), which is shared by polymyositis (PM) and inclusion body myositis (IBM), in relation to the p62 immunostaining pattern of muscle(More)
