    Description / Table of Contents: Summary Aneurysms of the temporal part of the carotid artery are unusually rare. The literature contains only a few previous reports dealing with hemorrhage from such malformations. In the present case massive bleeding occurred from a right-sided intrapetrous aneurym after myringotomy, which was performed as treatment for bilateral secretory otitis media. Due to the absence of any specific symptoms and the masking effect of middle ear glue preoperative identification of the aneurysm was not possible. Subsequent angiography showed the large fusiform extension of the intrapetrous aneurysm as well as multiple intracranial aneurysms. Leakage from the aneurism was closed definitively with muscle, fascia lata and a gelatin-resorcin-formalin-glue (Cardial®). In order to apply the tissue patch the hypotympanic site of the aneurism was exposed using a posterior otosurgical approach. Due to extensive intracranial collateralization to the vertebral arteries bleeding persisted even after ligation of both carotid arteries. Temporary cardiac asystole was then induced to allow safe closure of the aneurysm. Following surgery the patient sustained loss of hearing in her ear and a partial peripheral facial palsy.
    Notes: Zusammenfassung Aneurysmen der petrösen A. carotis interna sind extrem selten. Die wenigen publizierten Fälle waren Zufallsbefunde und überwiegend durch schwere Hämorrhagien bei Ohroperationen oder tubogene Epistaxis gekennzeichnet. In dem vorliegenden Fall trat nach einer Parazentese, die wegen adenoidassoziierter Paukenergüsse durchgeführt wurde, eine massive Blutung aus einem fusiformen Aneurysma der A. carotis interna auf. Die neuroradiologische Diagnostik ergab multiple, weitere intrakranielle Aneurysmen. Das petröse Aneurysma wurde über einen otochirurgischen Zugang mittels eines speziellen Gefäßwandklebers (Cardial) in gezielt herbeigeführter Asystolie, die wegen eines ausgeprägten, intrakraniellen Kollateralkreislaufes erforderlich war, verschlossen. Es kam zu keinen neurologischen Defiziten, allerdings resultierten eine Taubheit und eine angedeutete Fazialisparese. Der Bericht erweitert die einschlägige Literatur um eigene Erfahrungen in der Diagnostik und Therapie des blutenden, petrösen Karotisaneurysmas.

    Notes: Abstract It is well known that fixation of an imaginary target (IT) can influence the vestibulo-ocular reflex, but reports on the effect of peripheral vestibular stimulation on the localization of an IT are still lacking. In a prospective study, errors in pointing towards an IT without and after cold caloric vestibular stimulation (VS) were investigated in 24 right-handed volunteers with the head tilted backwards by 60°. After the stationary target had been extinguished for 120 s each subject had to point towards the target position as remembered in darkness. The vestibular response was recorded by electronystagmography. Without VS 73% of the volunteers showed a systematic horizontal pointing error towards the right side. VS led to an increased horizontal pointing error in the direction of the slow phase of the induced nystagmus and the degree of deviation showed a significant (P = 0.001) positive correlation (r = 0.32) with the amplitude of the calorically induced nystagmus. In summary, an IT is not merely a useful visual stimulus for influencing the vestibulo-ocular reflex during linear and angular acceleration. A peripheral vestibular stimulation is itself able to change the position of an IT significantly and the extent of deviation shows a significant correlation with the amplitude of the evoked nystagmus.

    Notes: N-TFA-γ-L-glutamyl-hypoglycin A α-ethyl ester was prepared by coupling N-TFA-L-glutamic acid α-ethyl ester with hypoglycin A according to the mixed anhydride method, using isobutyl chlorocarbonate. After removal of the protecting groups the resulting γ-L-glutamyl-hypoglycin A was found to be identical with natural hypoglycin B.

    Notes: 4-Hydroxycoumarin reacts with substituted salicylaldehydes, 2,6-dichloro- or -chloro-nitro-benzaldehydes to yield unstable 3,3′-benzylidene-bis-(4-hydroxycoumarins), intermediates which undergo ring closure with the hydroxyl group of one of the 4-hydroxycoumarin moieties, producing derivatives of 7-[4′-hydroxycoumarinyl-(3′)]-benzopyrano [ 3,2-c] coumarins.2,6-Dimethylbenzaldehyde, pyridine-2-aldehyde and 6-methylpyridine-2-aldehyde undergo a similar reaction.

    Notes: Einige Benzophenon-2-carbonsäuren liegen in festem Zustand vollstandig, in Dioxan- und Methanollosung weitgehend in der angegebenen Struktur vor. Ihre Saurechloride dagegen wurden nach verschiedenen Methoden ausschliesslich in der ψ-Form erhalten. Diese gibt bei der Umsetzung mit Alkoholen je nach den Redingungen wahre oder ψ-Ester. Sekundare Amine liefern wahre Ketocarbonsaureamide, wahrend Ammoniak und primare Amine ausschliesslich Derivate in der Lactamform gebcn. Die Grunde fur die Zuteilung dieser Strukturen werden diskutiert.
