OBJECTIVE To evaluate the role of copy number abnormalities detectable using chromosomal microarray (CMA) testing in patients with epilepsy at a tertiary care center. METHODS We identified patients with International Classification of Diseases, ninth revision (ICD-9) codes for epilepsy or seizures and clinical CMA testing performed between October 2006(More)
OBJECTIVE To quantify nerve conduction study (NCS) reproducibility utilizing an automated NCS system (NC-stat, NeuroMetrix, Inc.). METHOD Healthy volunteers without neuropathic symptoms participated in the study. Their median, ulnar, peroneal, and tibial nerves were tested twice (7 days apart) by the same technician with an NC-stat instrument.(More)
Homocystinuria usually presents with ectopia lentis, mental retardation, thromboembolic complications, and skeletal abnormalities. Whereas neuropsychiatric abnormalities are often recognized in untreated homocystinuria, initial presentation with acute psychosis has only rarely been reported. We describe a previously well 17-year-old adolescent with an acute(More)
PURPOSE F-wave studies are valuable tools in clinical neurophysiology. F-wave parameter estimation must be based on multiple F-wave traces due to their inherent variability. Repetitive supramaximal stimulation is uncomfortable for many patients. This study tested the hypothesis that submaximally stimulated nerves yield F-wave parameters equivalent to those(More)
INTRODUCTION Nerve conduction studies (NCS) are increasingly being performed at the point-of-service by family medicine, primary care, and internal medicine (FM/PCP/IM) physicians. Carpal tunnel syndrome (CTS) is a common neuropathy often diagnosed with the aid of NCS. METHODS A retrospective analysis of a point-of-service NCS data registry was conducted;(More)
