[Unilateral status epilepticus during the neonatal period]. / Les états de mal unilatéraux au cours de la période néonatale.

Twenty-one newborns displaying a strictly unilateral status epilepticus were studied. Three groups have been isolated according to the aetiology: neonatal anoxia (n = 5), postcardiac surgery (n = 8), cerebral hemispheric lesions confirmed by CT scan (n = 7). The authors relate in detail the clinical features and the EEG abnormalities, ictal and interictal in each group, and comment on their results. They show the importance of EEG in establishing or detecting a unilateral status epilepticus and in helping the aetiologic diagnosis.

[Study on focalized EEG paroxysms in children (author's transl)]. / Etude sur les paroxysmes EEG focalises de l'enfant.

The authors studied 111 children whose EEG showed paroxysmal foci on the lateral areas of the skull, often on the rolandic and temporal areas, but also on occipital, parietal and frontal areas. In 60% of the cases there was no clinical epileptic manifestation. In 25% of the cases those foci were responsible for epileptic seizures with good prognosis; in 15% of the cases they were associated with other epileptogenic processes responsible for epileptic fits of unfavorable evolution. The past history of these children had been studied in particular: hyperthermic convulsions and lateralisation difficulties were very frequent, but organic lesions were also found, which, although they did not seem to be directly responsible for the foci, were related to the organic lesion by a reactional or 'functional' factor.
