Video-EEG monitoring in respiratory chain disorders.

Subclinical epileptiform activity in patients with respiratory chain disorders (RCDs) has not been previously investigated by video-EEG monitoring. The purpose of this study was to look for the type and frequency of epileptiform activity during a 24 h-video-EEG recording in RCD patients. Eleven patients with RCD, 7 women and 4 men, aged 24-72 years, underwent a clinical neurologic examination, blood tests, CT/MRI scans of the brain, routine scalp EEG and continuous video-EEG monitoring over 24 consecutive hours. Ten patients had normal 24 h-video-EEG recordings. One of these patients had no CNS involvement; her resting EEGs showed diffuse background slowing. In one patient, automatic spike detection revealed 12 spikes during a 6 hour period. Resting scalp EEG in this patient showed extensive, bilaterally synchronous, pseudoperiodic polyspike-waves. In conclusion, subclinical epileptiform activity could be recorded by 24 h-video-EEG monitoring in only 1 of 11 RCD patients. The single patient with subclinical epileptiform activity presented with intermittent myoclonic jerks.

Spontaneous cerebral haemorrhage without hypertension in non-mosaic 45X Turner's syndrome.

Cerebral haemorrhage without hypertension, arteriosclerosis or clotting defect has not been reported in patients with Turner's syndrome before. In a 51 year old female patient with non-mosaic Turner's syndrome, acute aphasia and right-sided hemiplegia occurred, due to left-sided basal ganglia haemorrhage. The history for hypertension was negative, blood pressure was normal throughout hospitalisation as well as during 24 h monitoring, and all tests for secondary hypertension were negative. There was no indication of arteriosclerosis or a clotting defect. Since there were hypermobile joints, hyperextensible skin and ectatic ascending aorta and brachiocephalic trunk on angiography, a general connective tissue defect was assumed, making arteries more vulnerable to physiologically increased blood pressure and rupture of intracerebral arteries with consecutive bleeding.

[Current problems in epilepsy].

Three new aspects of epilepsy are discussed: the mesiotemporal syndrome, vagus nerve stimulation, and epilepsy and driving fitness. In recent years mesiotemporal epilepsy has been recognised as the most frequent epileptic syndrome in adults. The main clinical features are febrile convulsions during childhood, followed by characteristic focal seizures in the second decade of life. The typical seizure is characterised by an aura, followed by loss of consciousness, with motor phenomena and automatisms followed by longer periods of postictal confusion. Atrophy of the hippocampus and sclerosis are observed in MRI. The syndrome is frequently drug resistant, however, 80% of the patients are free of seizure after surgical treatment. Vagus nerve stimulation is a new option in the treatment of patients with drug resistant epilepsy (partial seizures with or without secondary generalization, Lennox-Gastaut syndrome), especially when surgical intervention is not indicated. Worldwide a total of more than 4000 patients have been treated. More than 50% reduction in the frequency of seizures can be obtained in 35-40% of drug resistant patients. Complications are rare. Finally, the issue of driving fitness and epilepsy as well as provoked seizures are discussed. The current regulations and laws are taken into consideration and revised regulations for Austria are suggested.
