Inflammatory and immune-mediated polyneuropathies represent an important differential diagnosis of hereditary and acquired polyneuropathies. In this article, we will provide you with all the relevant facts concerning the GuillainBarré syndrome, the Miller-Fisher syndrome, and the Elsberg syndrome. Also, we will cover the chronic-inflammatory demyelinating polyneuropathy (CIDP) and multifocal mo...

Radiation plexopathy produces numbness, weakness, and reflex changes.1 Excess motor unit activity (EMUA) after irradiation manifests as myokymia and neuromyotonia in affected muscles.2,3 A 65-year-old woman presented with a pulling sensation in the left axilla and intermittent depression of the left arm of 3 to 4 months duration. Ten months earlier she had completed chemotherapy and radiation t...

Although for many years insects were believed to be insensitive to curare (Harlow, 1958; Hopf, 1952; Krupp, Lendle & Stapenhorst, 1952; Roeder, 1948, 1953; Roeder & Weiant, 1950; Usherwood, 1963), the recent report of Larsen, Miller & Yamamoto (1966) has demonstrated that insects are, indeed, sensitive to curare. Subsequent investigations (McCann, 1966; Flattum, Friedman & Larsen, 1967; Friedma...

Intravenous immunoglobulin (IVIG) is the treatment of choice in patients with multifocal motor neuropathy with conduction block (MMNCB). Although IVIG is considered generally safe, neutropenia following IVIG infusion has been recognized as a rare hematologic side effect. Herein we report a patient with MMNCB who developed severe neutropenia following IVIG administration. A 41 year old woman pre...

We study numerically the dynamics of conduction blocks using a detailed electrophysiological model. We find that this dynamics depends critically on the size of the paced region. Small pacing regions lead to stationary conduction blocks while larger pacing regions can lead to conduction blocks that travel periodically towards the pacing region. We show that this size-dependence dynamics can lea...

Introduction: Motor skills play an important role during life span, and older adults need to learn or relearn these skills. The purpose of this study was to investigate how aging affects induction of improved movement performance by motor training. Methods: Serial Reaction Time Test (SRTT) was used to assess movement performance during 8 blocks of motor training. Participants were tested i...
