The basis for the consolidation of memory is a controversial topic, particularly in the case of motor memory. One view is that motor memory is transferred, partially or completely, to a new location during the consolidation process ("systems consolidation"). We investigated this possibility in a primitive motor system, the vestibulo-ocular reflex (VOR). In(More)
UNLABELLED The Pictorial Representation of Illness and Self Measure (PRISM) is a recently developed tool designed to measure the burden of suffering due to illness in a variety of patient populations. The purpose of the current study was to validate PRISM as a measure of suffering in patients with chronic non-cancer pain. Patients (n = 138) were recruited(More)
Motor memory is relatively labile immediately after learning but can become more stable through consolidation. We investigated consolidation of motor memory in the vestibuloocular reflex (VOR). Cats viewed the world through telescopic lenses during 60 min of passive rotation. Learned decreases (gain-down learning) and increases in the VOR gain (gain-up(More)
INTRODUCTION Pneumothorax is a potentially serious complication of electromyography (EMG). Data on the frequency of pneumothorax after EMG are lacking. The purpose of this study was to determine the frequency, timing, and risk factors for iatrogenic pneumothorax after EMG. METHODS Cases of pneumothorax after EMG were reviewed for clinical,(More)
IMPORTANCE Necrotizing autoimmune myopathy (NAM) is characterized pathologically by necrotic muscle fibers with absent or minimal inflammation. It is often accompanied by statin therapy, connective tissue diseases, cancer, and autoantibodies specific for signal recognition particle (SRP) or 3-hydroxy-3-methylglutaryl-coenzyme A reductase (HMGCR). Data are(More)
INTRODUCTION In acid maltase deficiency (AMD), electrical myotonia (EM) may be restricted to paraspinal muscles. A comprehensive description of the electromyographic (EMG) findings in AMD is lacking. The purpose of this study is to describe the EMG features in adult-onset AMD, focusing on the distribution of EM. METHODS A retrospective chart review of AMD(More)
BACKGROUND AND OBJECTIVES The association between prediabetes and distal polyneuropathy (DPN) remains controversial. Here we test whether the prevalence of small fiber sensory distal polyneuropathy is increased in prediabetes. METHODS Prospectively recruited cohorts of healthy subjects and those with prediabetes from Olmsted County, Minnesota, were(More)
Intracranial hemangioblastomas are benign vascular tumors. The peak age of incidence is between 20 to 50 years. Hemangioblastomas rarely occur in patients over the age of 65. To our knowledge there is no review of the prevalence and clinical features in an elderly population. We reviewed our 12 year experience with intracranial hemangioblastomas, and(More)
INTRODUCTION Adult polyglucosan body disease (APBD) usually presents with progressive spastic paraparesis, neurogenic bladder, and distal lower limb sensory abnormalities. It is caused by mutations in the glycogen branching enzyme gene (GBE1). METHODS We describe a woman with an unusual phenotype manifesting as progressive left brachial more than(More)
