    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: One known and four new alkaloids have been isolated from C. durissima STAPF. Isovoacangine (VII) (first isolated from Stemmadenia), conopharyngine (VIII), and possibly also Alkaloid E are monomeric isoquinuclidine bases found in root and stem bark; conodurine and conoduramine, however, are dimeric and found only in the roots. A mild and simple method is described for the decarbomethoxylation of ester bases of the voacangine type to substances of the ibogaine type.

    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: Preparation and properties of the stereoisomeric 2-dimethylamino-cyclohexanyl acetates and benzilates are described. The analogous mandelates cannot be prepared through the corresponding 2-chloro-2-phenylacetates because cis Z-dimethylamino-cyclohexanol reacts with 2-chloro-2-phenylacetyl chloride to form the quaternary chloride VIII, and trans 2-dimethylamino-cyclohexanyl 2-chloro-2-phenylacetate, with water, suffers saponification prior to substitution.
