    Notes: Abstract We examined 72 patients with 89 angiographically confirmed intracranial aneurysms, using transcranial colour-coded duplex sonography (TCCD) to determine the location and size of the aneurysm. The patients were admitted for coil embolisation of their aneurysm following subarachnoid haemorrhage or because of a cranial nerve palsy. Using a 2/2.25 MHz transducer, 42 aneurysms (47 %) were seen satisfactorily through the temporal bone window or foramen magnum. In 24 cases (27 %) image quality was insufficient as a result of a poor bone window, of the aneurysm having a diameter of less than 6 mm or of its being in an unfavourable location. In 23 other cases (26 %) it was not possible to detect the aneurysm. Thrombosed structures could be demonstrated using TCCD in 8 of 12 giant intracavernous or basilar artery aneurysms, and in 15 of 19 aneurysms treated by platinum coil embolisation. TCCD offers a noninvasive method for monitoring progressive intra-aneurysmal thrombosis following coil embolisation and for follow-up of patients with untreatable fusiform aneurysms, should this be required. Detection of small aneurysms is limited by spatial resolution and insonation angles.

    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 Cerebrospinal fluid (CSF) leakage may occur spontaneously, iatrogenically or from spinal trauma. Postural headache is the cardinal symptom; dizziness, diminished hearing, nausea and vomiting are additional symptoms. In neurological examinations cranial nerve palsies may be found. Due to low CSF pressure neuroimaging studies may reveal dural enhancement and vertical displacement of the brain. We describe a patient with the history of an uncomplicated lumbar discectomy at the level L4-5 and the typical clinical symptoms of intracranial hypotension. MRI of the craniocervical junction schowed typical features of a Chiari type-I malformation. After neurosurgical ligation of a CSF leak at L4-5 caused by lumbar disc surgery, the patient was free of orthostatic headache. A repeated MRI showed a striking reduction of the previous downward displacement of the cerebellar tonsils and pons.
