F-responses in syringomyelia

Journal of the Neurological Sciences
S Peioglou-HarmoussiD D Barwick

Abstract

Motor and sensory nerve conduction and various F-response parameters have been examined in the median and ulnar nerves bilaterally in 22 patients with syringomyelia. Excluding those nerves with isolated peripheral lesions, motor and sensory conduction was normal in the distal nerve segments, except for one subject in whom severe wasting of the muscles was associated with slowed motor velocities. Minimum and/or maximum F-response latencies were increased in one or more nerves in 16 of the 22 cases, which was attributed to disturbed function of anterior horn cells and the intraspinal segment of the motor fibres, or mild subclinical nerve trauma. There was a tendency for F-response amplitude and duration to be increased, probably reflecting the combined effects of spasticity and enlargement of motor units due to reinnervation.

Cachexia & Brown Fat

Cachexia is a condition associated with progressive weight loss due to severe illness. In cancer patients, it is proposed to occur as a result of tumor-induced energy wasting. Several proteins have been implicated in browning and depletion of white adipose tissue. Here is the latest research on cachexia and brown fat.

Cardiac Cachexia

Cardiac cachexia is a syndrome associated with the progressive loss of muscle and fat mass. It most commonly affects patients with heart failure and can significantly decrease the quality of life and survival in these patients. Here is the latest research on cardiac cachexia.

Cardiac Conduction System

The cardiac conduction system is a specialized tract of myocardial cells responsible for maintaining normal cardiac rhythm. Discover the latest research on the cardiac conduction system here.
