[Density and dynamic of frontal sharp waves (encoches pointues frontales) during sleep in new-borns and infants (author's transl)].

Frontal sharp waves (encoches pointues frontales) identified by Monod (1960) were studied in 110 neonates and infants. Three pattern were described: typical, related and degraded. They were recorded in all subjects, the reason why the frequency of each pattern varied was discussed. Pathological states did not increase the occurrence of those frontal sharp waves since most of them were recorded in children either normal or suffering from a minor pathology. Incidence of maturation seemed to be probable since the highest proportion of frontal sharp waves occurred in infants whose gestational and legal age were respectively greater than 43 weeks and between 20 and 40 days at the time of investigation. Typical and degraded forms were predominant in transitional period towards quiet sleep; they were less numerous during falling asleep in active sleep and totally absent during active sleep following quiet sleep. This could suggest that the two states of active sleep are different in nature.

[Lambda waves in the neonate (author's transl)].

Different types of sharp elements can be observed over the occipital regions from the 2nd postnatal week in the open-eyed child, with active eye movement but practically no body movement. Certain of these sharply localised elements in the occipital midlin are identical to adult lambda waves. Their early occurrence calls to mind the emergence of visual function and attention, these latter occurring at the end of the neonatal period between 7 and 9 days.

[An electroencephalographic study of disorders of amino-acid metabolism during the first days of life (author's transl)].

The authors have attempted a systematic E.E.G. study in 32 neonates suffering from disorders of amino-acid metabolism, during the first days of life. These consisted of cases with ketosis (13 cases of leucinosis, 5 methylmalonic acidaemia, isovaleric acidaemia and 3 with hyperlactacidaemia) and cases without ketosis (6 cases of hyperglycinaemia and 3 with congenital hyperammonaemia). A study of the E.E.G. showed some characteristic features, the most typical of which were: -a periodic tracing with large sharps complexes intermingled with less active periods occurring in every case of hyperglycinaemia without ketosis, in 2 cases of leucinosis and 2 cases of methylmalonic acidaemia. This record indicates a poor prognosis. -a less stereotyped periodic tracing with variable evolution. -distinctive figures characterised by rapid Rolandic rhythms always found in cases of leucinosis compared with sharp spindles (between the 10th and 30th day). It is concluded that the E.E.G. patterns are not in close correlation with the anatomical lesions.

[Clinical course following a neonatal E.E.G. recording reported as severely abnormal (author's transl)].

The purpose of this study was to evaluate the prognostic value of neonatal E.E.G. tracings in children born at term. The clinical course of 45 children was followed and related to E.E.G. abnormalities reported during the first 5 days of life. Essentially the findings confirmed those previously reported by others. However some differences were noted: paroxysmal tracings were not associated with a poor clinical state, and moderately abnormal tracings (the prognostic significance of which has never been defined) led on sometimes to a severe encephalopathy. We wish to stress certain aspects of our findings: -recordings in the first 24 hours of life may be misleading. -recordings, to be of value, must be taken before any treatment which could induce paroxystic E.E.G. patterns. -E.E.Gs should be repeated during the post-natal period when the findings are non-specific. -the prognostic significance of tracings reported as "generalised or localised overactivity" should be evaluated.

[The E.E.G. during althesin anaesthesia in paediatrics (preliminary study) (author's transl)].

The authors studied 11 children (mean age 5 1/2 years) before and during anaesthesia, and then several times from 1 to 6 hours after the injection of althesin. The anaesthetic agent was either pure althesin or althesin combined with dextromoramide. The electroclinical correlations described for adults are also found in children: slow waves, discontinuous and then isoelectric recording during the operation stage, then rapid recovery after ending drug administration. The special interest of this study was the analysis of E.E.G. recordings during the hours following clinical recovery: only once was the recording like that of full consciousness. Repeated recordings were all of drowsiness and even sleep, despite the clinical state of the subject. A short associated study concerns the E.E.G. of neonates during their first 24 hours, born to mothers anaesthetised with alfathesin.
