Unilateral thalamic stroke does not decrease ipsilateral sleep spindles.

Study Objectives: To measure the sleep spindle characteristics in patients with unilateral thalamic stroke.

Design: A prospective study of patients with thalamic stroke and age-matched healthy controls.

Setting: Department of Neurology of a University Hospital.

Brain impairment in well-nourished chronic alcoholics is related to ethanol intake.

To determine the influence of chronic ethanol intake on the central nervous system, we studied 40 asymptomatic, well-nourished, chronic alcoholics (mean age, 42.6 +/- 9.1 years) and 20 age-, sex-, and education-matched control subjects.

[Ototoxicity of deferoxamine].

Deferoxamine or desferrioxamine (DFO) is a chelating agent, largely used in patients with chronic renal failure, although it has many side effects, being ototoxicity one of them. In this paper we studied the eventually adverse otologic effects of DFO in 20 patients receiving haemodialysis. A complete audiological evaluation, including pure-tone audiometry, brainstem auditory evoked potentials and high-frequency audiometry, was performed.

[Auditory evoked potentials in chronic alcoholism].

Prospective study of about 42 chronic alcoholics and evaluation, by means of auditory evoked potentials, of their auditive pathways. Checking of the damage at the outmost degree of the pathway, in alcoholic encephalopathy. Discussion and evaluation of the tracings.
