ABSTRACT
Background: Stroke is the second cause of mortality and the first cause of morbidity in Chile and worldwide. Nowadays there is a major interest in introducing new therapies applying evidence based medicine for these patients. Aim: To describe the clinical profile of patients attended after a stroke, to determine stroke subtypes and their risk factors. Material and methods: Retrospective review of clinical records of 459 patients (mean age 65±48 years, 238 female) that were admitted to our unit during a period of 37 months. Results: Sixty three percent of patients had an ischemic stroke, 14% had an hemorrhagic stroke, 15% had a transient ischemic attack, 2% had a cerebral venous thrombosis and 6% a subarachnoidal hemorrhage. The global mortality was 1%. Seventy percent of patients had a history of high blood pressure. Conclusions: The most common type of stroke is ischemic and high blood pressure is the main risk factor.

Pure Autonomic Failure is a progressive, adult onset, degenerative disorder of the autonomic nervous system characterized clinically by orthostatic hypotension, bladder, sexual and sudomotor dysfunction. Since there are no other associated somatic neurological deficits, this condition must be considered in the differential diagnosis of orthostatic hypotension. We report a 64 years old man with a history of seven years of autonomic dysfunction, with severe orthostatic hypotension, erectile and bladder dysfunction. Autonomic tests showed low circulating norepinephrine levels, sweating abnormalities with regional anhydrosis of the left side of the trunk and abnormal cardiovagal response, indicating generalized autonomic failure. Peripheral somatic neuropathies with autonomic involvement were excluded by normal electrophysiologic tests and the patient was diagnosed pure autonomic failure. Treatment with fludrocortisone and midodrine improved orthostatic tolerance.

Ha habido importantes avances en el conocimiento del metabolismo del triptofano, la síntesis de serotonina y los receptores serotoninérgicos encefálicos. Se ha determinado la efectividad terapéutica del 5-hidroxitriptofano en la depresión, insomnio, dolor crónico, mioclonías, etc. Eso sí, ha surgido inquietud al establecerse, como efecto adverso del tratamiento con L-triptofano, la producción del síndrome de mialgia-eosinofilia con compromiso importante de las fuerzas debido a una polineuropatía
