[Recurrent confusional states and periodic lateralized epileptiform discharges: a new type of non-convulsive status epilepticus?].

Periodic lateralized epileptiform discharges (PLEDs) in an EEG usually indicate the presence of an underlying structural lesion (of vascular origin in most cases). PLEDs are also sometimes observed in certain types of infections (mainly viral), in which they may even constitute a characteristic finding useful for diagnostic purposes. In recent years cases have been reported in which PLEDs are linked to recurring confusional states that do not fit in with established classifications and that may be epileptic in nature. We discuss the cases of 2 patients who were repeatedly admitted to our hospital in confusional states, in whom PLEDs were observed in EEG readings. Clinical evolution in both cases paralleled EEG alterations. We were able to perform both critical and intercritical single proton emission tomography on 1 patient, finding, respectively, hyper- and hypoabsorption foci. Symptoms resolved with antiepileptic treatment.

[Prognosis of supratentorial parenchymal hemorrhages].

The prognostic value of a group of parameters recorded upon hospital admission was assessed in a series of 135 supratentorial hemorrhages. The patients were divided into 3 groups based on survival < 30 days, between 30 days and 1 year, or > 1 year. Patients in the group with the shortest survival period were older; had more Glasgow scale scores < or = 10 and more Canadian scale scores < or = 5; had more hematomas > or = 4 cm in diameter revealed in computerized tomography with frequent midline shift and frequent ventricular hemorrhagic invasion; had higher stress reaction (hyperglycemia, leukocytosis and heart arrhythmia). Cholesterinemia, however, was lower in the shortest survival group. A range of quality of life was observed in the group (44%) with survival longer than 1 year. The subgroup with motor independence (Rankin < 3) (19%) differed from those with less motor independence (Rankin > or = 3) in that they were younger, more often had mean scores > or = 5 on the Canadian scale and normal blood pressure levels. We conclude that prognostic value of the clinical evaluation scales used, along with age and size of hematoma, was good.

[Prognostic factors of supratentorial cerebrovascular accidents].

Our aim was to delimit prognostic factors in supratentorial stroke based on data obtained upon hospitalization. We studied two series of patients, the first being 150 with brain infarct and the second 135 having intracerebral haemorrhage. We analyzed: age, Glasgow and Canadian scales, glucose and urgence haemogram and the size of the lesion across its greatest diameter using computerized tomography (CT). Follow-up time was until death or one year after the stroke. Those who lived longer than one year after were subclassified according to the Rankin scale as < 3 and > or = 3. There was a significant difference between those who survived for less than one month and those surviving more than one year: their age (p < 0.01), average score on the scale (p < 0.001) and size of infarct (p < 0.05) or haematoma (p < 0.001). The Rankin subgroups < 3 and > or = 3 also differed significantly with regard to age. Noteworthy were the unfavourable data: Glasgow < 10 points and Canadian < 5 points, in infarcts > 6 cm and haematomas > 4 cm in diameter. We comment on other evolutionary variables which may influence prognostic assessment such as clinical deterioration or CT sensitivity of the infarct depending on the carry-out time.
