The authors report two cases of amyotrophic lateral sclerosis (ALS) misdiagnosis (a craniocervical junction disorder, and a cervical spinal cord ependymoma). They review some causes of ALS-like syndrome and propose a protocol to be adopted for the study of all patients who present clinical abnormalities suggesting ALS.
The authors studied serum and urinary calcium and phosphorus levels, as well as abnormalities on the spine of 30 patients with motor neuron disease. The authors believe in multifactorial aspects in the pathogenesis of motor neuron disease, calling special attention to toxic and metabolic factors.
The authors describe the neurological manifestations of a female patient with hypercholesterolemia who developed myopathy in the course of her treatment with clofibrate. After the drug was tapered off, the neurological signs and symptoms disappeared. Therefore, attention is called for the importance of the differential diagnosis of iatrogenic myopathies with polymyositis.
Peripheral neuropathy is a rare manifestation in hyperthyroidism. We describe the neurological manifestations of a 38 year old female with Graves' disease who developed peripheral neuropathy in the course of her treatment with propylthiouracil. After the drug was tapered off, the neurological signs disappeared. Therefore, we call attention for a possible toxic effect on peripheral nervous system caused by this drug.
