We report a case of a 26-year-old man who presented a lower motor neuron syndrome due to hyperparathyroidism. Electromyography showed neurogenic features with normal nerve conduction studies. Hypercalcemia led to the discovery of a primary hyperparathyroidism with gland hyperplasia. Following parathyroid surgery there was recovery of the neurological(More)
BACKGROUND Restoration of nerve continuity and effective maintenance of coaptation are considered fundamental principles of end-to-end peripheral nerve repair. OBJECTIVE To evaluate the influence of the number of stitches on axonal regeneration and collagen production after neurorrhaphy. METHODS Thirty male Wistar rats were equally divided into 3 groups(More)
Although deep brain electrical stimulation can alleviate the motor symptoms of Parkinson disease (PD), just a small fraction of patients with PD can take advantage of this procedure due to its invasive nature. A significantly less invasive method--epidural spinal cord stimulation (SCS)--has been suggested as an alternative approach for symptomatic treatment(More)

Excitotoxicity is the major component in neuropathological conditions, related to harmful action of imbalanced concentrations of glutamate and its agonists in the nervous tissue, ultimately resulting in cell death. In the present study, we evaluated the effects of an acute striatal lesion induced by a focal N-methyl-D-aspartate (NMDA) microinjection on the(More)
