[Clinico-morphologic features of subacute anterior poliomyelitis].

The paper deals with clinical and morphological studies of 2 cases with subacute anterior poliomyelitis. The authors attract special attention to the development of flaccid pareses with a simultaneous inhibition of tendinous and periosteal reflexes, the absence of any pyramidal signs during the entire disease and a clear prevalence of degeneration in spinal cord motoneurons in the cervical and thoracel parts and their preservation in the brain cortex. These symptoms are distinctive signs from the poliomyelitic variant of the amyotrophic lateral sclerosis.
