[Behavior disorder of the REM sleep in 2 documented cases with polysomnography].

We report a 69 years old male with a parkinsonian syndrome and a 50 years old female without neurological problems who showed violent behavior during REM sleep. Polysomnography showed that both bad tonic or phasic muscular activity during REM sleep and a REM sleep behavior disorder was diagnosed. Clonazepam was used in both, with good clinical response. This condition is frequently unrecognized and confused with nightmares, nocturnal delirium or other parasomnias.

[Foramen ovale electrodes in the study of temporal lobe epilepsy].

Corticograms of the mesial structures of the temporal lobe may be obtained with the recently developed foramen ovale electrodes. Since their installation is easy and of low risk, they will probably displace other invasive techniques routinely used up to the moment for the localization and lateralization of epileptic foci originated in the temporal lobe. For the first time in our country, we have used this technique in 7 patients with medically intractable complex partial epilepsy. In all the patients, the study allowed to clear doubts about the laterality of the start of ictal activity and to define irritative foci not found with conventional continuous superficial electroencephalographic recordings. The procedure was uneventful and the implanted electrodes were optimally tolerated. Foramen ovale electrodes are an effective diagnostic method for temporal lobe epilepsies and their features are specially appropriate for our milieu.

[Sleep stages and growth hormone in manganese poisoning. Effects of L dopa].

Sleep characteristics are studied in 7 patients with sequelae of manganese intoxication and in 8 controls. A reduction in the length of the REM stage was observed, which could be prolonged by L Dopa administration, but without achieving values comparable to the controls. No changes were noted in the non-REM stage of sleep. These results are similar to the ones obtained in Parkinson's disease, suggesting clinical and probably biochemical similarities between the 2 conditions. The blood concentrations of growth hormone during sleep in the manganic patients was lower than in the control group, and no significant variations were noted after L Dopa administration.
