摘要:

This study evaluates morphologically the sural nerves of two patients with acute and another pair with chronic uremia, both of whom had neither clinical nor electrophysiologic evidence of neuropathy. Morphometric changes indicative of myelin repair were noted in the chronic uremic case who had a shorter duration of renal failure but required dialysis. Also, changes suggestive of axonal degeneration were found in the case who had chronic uremia of long duration. Both cases of acute uremia did not reveal significant abnormalities. Structural changes in the sural nerves may precede clinical and nerve conduction derangements in uremia, specifically in chronic cases.

摘要:

In addition to the benzodiazepine antagonism we report, as a first observation, the effect of flumazenil on carbamazepine intoxication, where a mechanism other than benzodiazepine receptor antagonism must be supposed.

摘要:

Reports of epileptic seizures evoked by eating are very scarce in the literature. A review of the reported cases suggests that various mechanisms may act as triggering factors in this form of reflex epilepsy. We studied a 17-year-old boy in whom the seizures precipitated by eating had been prevented by giving him some alerting stimuli during the meal. The attention-arousal coupling sustained by the meal seems to play a role in triggering the attacks.

摘要:

Blink reflex (BR) was examined serially in patients 1, 2 and 3 months after unilateral hemispheric cerebrovascular accident and compared with functional state and CT findings of lesion extent and location. BR R2 components were depressed and correlated with lesion size. Initial walking ability was correlated with latency and amplitude of both direct and consensual R2 elicited by stimulation of the paretic side. No correlation was found between BR and arm function or the final ambulatory ability. A model suggesting a close association between BR projection-facilitating fibers and those mediating facial movements is presented.

摘要:

Lupus anticoagulant is more often associated with thromboembolism than hemorrhage. We have observed two cases of lupus anticoagulant associated with basal ganglion lacunar infarction, causing contralateral choreoathetosis. One patient had no evidence of lupus or other etiology, and responded to antiplatelet therapy, while the other was found to have systemic lupus erythematosus with nephritis and was successfully treated with steroids. The effects of lupus anticoagulant on platelet prostacyclin receptors or prostacyclin production, or its effect on cerebral vessels may permit small-vessel occlusion and lacunar infarction in susceptible patients.
