    Description / Table of Contents: Zusammenfassung Bei 112 unter Monotherapie mit Carbamazepin, Phenytoin, Primidon oder Valproat stehenden erwachsenen Anfallskranken sowie bei 19 gleichaltrigen Kontrollpersonen wurden radioimmunologisch die Vasopressin-Plasma-Konzentrationen bestimmt. Es wurden keine signifikanten Unterschiede zwischen den Gruppen gefunden. Einige der mit Carbamazepin und Primidon monotherapierten Epileptiker wiesen niedrige Vasopressin-Werte auf. Die Carbamazepin-Serumspiegel korrelierten nicht mit den Vasopressin-Konzentrationen. Somit ergab sich weder ein Hinweis auf eine vermehrte Vasopressin-Ausschüttung unter Langzeittherapie mit Carbamazepin noch eine besondere Hemmung der Ausschüttung durch Phenytoin.
    Notes: Summary Plasma arginine vasopressin concentrations were determined by radio-immunoassay in 112 adult epileptics who were taking carbamazepine, phenytoin, primidone, or sodium valproate in long-term monotherapy, and in 19 controls. No significant difference was found between the groups, but some epileptics taking carbamazepine and primidone showed low values. Serum concentrations of carbamazepine did not correlate with the concentrations of plasma arginine vasopressin. In conclusion, there was no evidence of a stimulating effect of chronic carbamazepine medication or a special inhibiting effect of phenytoin on the release of vasopressin arginine from the posterior pituitary.

    Notes: Abstract Eighteen patients with dural arteriovenous fistulas or intradural arteriovenous malformations underwent clinical and neurophysiological examination. Bladder disturbances, pain, sensory abnormalities and involvement of both upper and lower motor neurons were commonly observed. Abnormal findings were obtained both in electromyography (11/18) and somatosensory evoked potentials (16/18). The motor evoked potentials were abnormal in all but one patient and showed a prolonged central (n = 14) or peripheral motor conduction time (n = 6). In three cases both values were prolonged. The results of nerve conduction studies in the patients with prolonged peripheral motor conduction times were normal. These neurophysiological findings may indicate root involvement in some patients, probably due to venous congestion and consequent hypoxia, as there were no signs of root compression on neuroradiological evaluation in any of these six patients. Motor evoked potentials may provide an additional clue to the diagnosis, although patients with spinal stenosis or motor neuron disease may present with similar findings.

    Notes: Summary Twenty patients with different types of muscular dystrophy (MD) were included in a cross-sectional study by means of electrocardiography and ultrasound cardiography. A manifest cardiomyopathy was detected in 8 patients; a latent cardiomyopathy was found in 4. A hypertrophic cardiomyopathy was especially frequent in facioscapulohumeral MD, a congestive cardiomyopathy in Becker-Kiener MD. The ECG showed a reduction in the QT interval and frequent block formers in the X-chromosomal inherited forms and the trunc-girdle form. Bradycardia and a prolonged QT interval were frequent in myotonic dystrophy and facioscapulohumeral MD. Signs of cardiac infarction in the ECG were most frequent in the trunc-girdle forms. A high cardiac output per minute in conjuction with increased left ventricular volume was frequent in Becker-Kiener, and Landouzy MD. A left ventricular dysfunction with reduced ejection was characteristic of myotonic dystrophy and truncgirdle MD. A mitral valve prolapse was more frequent with increasing severity of the muscle disease and was particularly frequent in myotonic dystrophic and Landouzy MD. The cardiac output per minute and the stroke volume were significantly lower (P≤0.03) where a mitral valve prolapse was present.
