[Assisted ventilation of newborn infants during sleep. Study of factors modifying adaptation to ventilation].
During sleep, of ventilated newborns and young infants, spontaneous respiratory movements may occur, unrelated to the ventilation impulsions. The respiratory pattern is then classified as "active". On the contrary, the respiratory pattern is classified as "passive", when all respiratory movements are related to the ventilation insufflation. ⋯ A rapid rate of ventilation (superior to 30/minute) is rarely related to an active respiration; a slow rate of ventilation seems favor this respiratory pattern. It is clear that adaptation to artificial ventilation is better during quiet sleep than during active sleep. Some physiopathological considerations are developed.

[Value of cassette-recorded long-term 8-channel EEG monitoring in status epilepticus--technical note].
Prolonged EEG-taped recording is a significant recent improvement in technique, with the 8 channels providing the possibility of exploration of the whole scalp. First used for ambulatory monitoring, it was also tested in comatose patients with status epilepticus. The advantages are: the the good quality of the EEGs even after recording continuously for many days, and without drawback for intensive nursing; the help in recognizing infraclinical seizures, often misunderstood by the nursing staff, and the control of treatment; the participation in prospective chronobiological studies.

[Monitoring the integrity of saccadic eye movements as a test of post-anaesthetic recovery (author's transl)].
After reviewing various tests of consciousness which can be used during the post-anaesthetic period, the authors chose to analyse the involvement of the visual receptor during different stages between sleep and complete recovery of consciousness, by an electro-oculographic (EOG) method, providing recordings of the displacement of the optical axis. In states of full consciousness the eye explores a static flat surface in saccades separated by pauses. ⋯ In a second group, the state of consciousness was monitored 2 hours after the last injection of the anaesthetic drug, so that correlations could be considered with the type of anaesthesia used. Th conclusion concerns the practical interest of the method (short term hospitalisation after general anaesthetic, medico-legal use due to the existence of a recording) and its basic use in the experimental study of new drugs in man.

["Spike focus" during the evolution of febrile convulsion: an electrophysiological and clinical study of 35 patients (author's transl)].
Out of 500 patients with febrile convulsions, 41 were found to have a spike focus on E. E. G., 35 of these were then followed up. ⋯ In 35 patients the focus disappeared, in 45 p. 100 within a year and in 88 p. 100 within 3 years. Following the disappearance of the focus, generalised sharp wave activity was seen in 30 p. 100 cases, all 35 children being under treatment. All the seizures with the exception of two children who have become epileptic were benign rendering long term anticonvulsant therapy unnecessary.
