Acute necrotizing mediastinits: a series of four patients

Visual, brain stem auditory and somatosensory evoked potentials (EPs) have been traditional paraclinical tests to evaluate the competency of sensory tracts in MS patients. It seems that only one of these EPs could be sufficient, at least as a screening test. The objective of this paper is to evaluate the frequency of these three evoked potentials in definite MS patients. This descriptive cross-sectional study involved was 25 definite relapsing remitting MS patients who referred to our university hospital. Twenty five individuals from normal population without any neurologic, visual, auditory or sensory disorders have been evaluated as well to determine the standard values in our electrophysiology lab
