[Clinical characterization of 450 patients with cerebrovascular disease admitted to a public hospital during 1997].

BACKGROUND: In Chile, cerebrovascular diseases are the fifth cause of death among men and the third cause among women. AIM: To assess the clinical features and management of patients with cerebrovascular disease admitted to a public hospital during 1997. PATIENTS AND METHODS: A retrospective analysis of clinical records of patients discharged with a diagnosis of cerebrovascular disease. Those records in which there was discordance between the discharge diagnosis and the clinical picture were not considered in the analysis. RESULTS: Of the 563 discharges from the hospital with the diagnosis of cerebrovascular disease, 487 records were located and 450 were considered in the analysis. Fifty four percent of patients were male and ages ranged from 17 to 96 years old. Fifty-one percent of patients had an ischemic stroke, 34% a cerebral hemorrhage, 12% a subarachnoidal hemorrhage and 3% a transient ischemic attack. There was a history of hypertension in 64% patients and 20% had an adequate treatment. Eighteen percent were diabetics, 34% had a heart disease and 20% had a previous episode of stroke. Mean hospital stay was 6.3 days in the emergency room and 11 days in the neurology ward. Hospital infections appeared in 21% of patients (respiratory in 68% and urinary in 22%), lethality was 30.5% and a CAT scan was done in 94%. At the moment of admission, 10% of patients had an evolution of less than 2 hours, 27% had an evolution between 2 and 6 hours and nine cases were potential eligible for thrombolysis. CONCLUSION: This is a picture of the local features of patients with cerebrovascular diseases that can be used as a reference for future studies.

[Somatosensory evoked potentials and symptomatic response to dopaminergic drugs in Parkinson's disease].

Short latency somatosensory evoked potentials were measured in 10 patients with Parkinson's disease before and after the administration of Apomorphine 5 mg sc. Eight of these subjects were reassessed after one month of treatment with Levo-Dopa. These potentials were measured in other nine subjects before and after one month of treatment with Selegiline 10 mg od. There was a significant increase of frontal potential N30 in nine of 10 subjects that received apomorphine, in seven of eight patients treated with Levo-dopa and seven of nine patients treated with Selegiline. No changes in N20 parietal potential were observed. During apomorphine test, changes in N30 potential preceded clinical improvement in six patients and occurred simultaneously in three patients. No changes with apomorphine in N30 potential were observed in two healthy males. There was no relationship between electrophysiological changes and duration of disease or motor fluctuations. It is concluded that short latency somatosensory evoked potentials are an objective means of measuring dopaminergic response in patients with Parkinson's disease.
