    Notes: Summary The caloric stimulation is the only possibility how the otolaryngologist may examine separately the function of the vestibular organs. But in patients with chronic mesotitis and a tympanic perforation, we were not able to irrigate the labyrinths, and therefore had no knowledge of labyrinthic defects in those patients. Our new method — called thermostimulator — now allows us, to irrigate the ears with tympanic perforations. 75 patients were tested. 50 ears with a central perforation had a labyrinthine defect of 9.5% compared with the normal side, in 33 ears with a cholesteatoma, we found a defect of 33.2%.

    Das Nystagmusverhalten nach längeren thermischen Reizen (1979)

    Notes: Summary During a long time constant thermic stimulation of the labyrinth a well known decay of nystagmus occurs due to a central compensatory reaction. Short time after termination of the stimulus we saw a marked increase of nystagmus, which can be explained neither by thermic processes in the temporal bone nor by compensatory reactions alone. This phenomenon will be described in dependance of different stimuli.

    Description / Table of Contents: Zusammenfassung 5 aus lyophilisierter menschlicher Dura (LMD) hergestellte und Hunden implantierte Arterienprothesen wurden nach 4, 5 1/2, 13, 43 und 46 Monaten entnommen und elektronenmikroskopisch untersucht. Die Neointima aller Implantate bestand aus Pseudo-Endothelzellen, Fibrozyten und Kollagenfibrillen. 43 und 46 Monate nach Implantation waren außerdem glatte Muskelzellen und elastische Mikrofibrillen in der Neointima vorhanden. Diese entsprach somit in ihrer Zusammensetzung im wesentlichen der Neointima von Kunststoff- und Kollagen-Kunststoff-Arterienprothesen. Die klinische Erprobung von LMD-Implantaten als arterieller Gefäßersatz ist jedoch wegen degenerativer Wandveränderungen in den Prothesen mit fast vierjähriger Verweildauer vorerst noch zu früh.
    Notes: Summary Five arterial prostheses made of lyophilized human dura (LHD) were inserted into dogs and removed after 4, 5 1/2, 13, 43, and 46 months to be studied with the electron microscope. The neointima of all grafts consisted of pseudo-endothelial cells, fibrocytes, and collagen fibrils. Additionally, 43 and 46 months after implantation smooth muscle cells and elastic microfibrils were present. Thus, the composition of the neointima was substantially identical with that of the neointima of synthetic arterial grafts and collagenfabric ones. The clinical application of arterial prostheses of LHD, however, seems at present too early because of degenerative changes in the walls of those grafts which remained nearly 4 years in the dogs.

    Notes: Summary The spatial distribution of inhibitory effects mediated by spino-olivocerebellar pathways and evoked by stimulation of the FRA was studied in Deiters' nucleus by intracellular recordings and extracellular measurements of positive field potentials. At a given recording site individual nerves greatly varied in their effectiveness: Q and Saph, Tib and FDL were usually the most effective, while GS had very little effect. When comparing several recording sites, various patterns of dominating and nondominating nerves were found, resulting in a somewhat patchy distribution of responses. The results were supported by intracellular recordings, which showed that CF-mediated IPSPs can be evoked from a limited number of nerves only. The findings show that a discriminative pattern exists in the FRA-evoked spino-olivocerebellar-mediated inhibition. In addition, Deiters neurones were found in which the inhibition was evoked from a large number of fore- and hindlimb nerves. Such a generalized inhibitory pattern may be involved in interlimb coordination during locomotion.

    Notes: Summary Maximum reaction following accelerated optokinetic stimulation in human is about 40°/s. These maximal values remain constant even by increasing stimulation. The stimulation rates are not physiologically. Under the conditions of such long and not physiological stimulations hormons of pituitary were determined. Immediately after the stimulation as well as 15 min later, elevated ADH levels were measured. Serum levels of hGH and cortisol remain unchanged, whereas serum prolaktin levels decrease slightly.

    Die optokinetische Untersuchung mit Reizbeschleunigung im Vergleich zu konstanten Reizen (1978)

    Notes: Summary Earlier investigations showed the optimal parameters for the optokinetic test with accelerated stimuli. The acceleration is 1.2 degrees/s2 and the maximum stimulus velocity is 40 degrees/s. As we can show now, this test for patients is much more difficult than the tests with constant velocities. As a result we gain more pathologic results. We compared the accelerated tests with constant velocities of 20, 40, and 60 degrees/s.

    Notes: Summary Using a semiautomatic off-line analysis of nystagmus the examiner decides whether an eye-movement is a nystagmic beat or not. We use as base for our development a device described by F. Guedry and A. J. Benson, which measures the speed of slow component (y-axis) and the time course (x-axis) with two potentiometers. We summarize the voltage of y-axis in variable periods and display them as degree per second. The voltage of x-axis is displayed directly. The output is performed digitally, on a digital pointer, on a x-y recorder and in ASCI code for further computerization.

    Description / Table of Contents: Zusammenfassung Die Verwendung eines halbgeschlossenen Wasserkreislaufsystems verhindert, daß Wasser als temperierendes Medium mit der Gehörgangshaut in Berührung kommt. Dies bedeutet, daß die calorische Reizung auch bei Patienten mit Trommelfellperforationen angewendet werden kann. Dadurch ist zum ersten Mal auch bei dieser Patientengruppe die Voraussetzung für einen Seitenvergleich geschaffen. Das halbgeschlossene Wasserkreislaufsystem wird erzielt durch Verwendung einer sehr kleinen Blase aus dehnbarem Material, die sich innerhalb des Gehörgangs aufbläht und sich an die Gehörgangswand anlegt. Die Ausdehnung der Blase wird verursacht durch Überdruck des calorisierenden Wassers innerhalb der Blase. Der Überdruck wird erzeugt durch verschiedene Kaliberweiten von zu- und abführenden Wasserkanälen, wobei der das Wasser zuführende Kanal ein größeres Kaliber hat als der das Wasser abführende. Die beiden Kanäle sind konzentrisch.
    Notes: Summary The use of a semi-closed water circuit keeps the tempering medium water from direct contact with the external ear canal so that caloric stimulation can he used to obtain exact data even in patients with perforated ear drums. A semi-closed circuit is achieved by the use of a very small bladder of expansible material which expands inside the external ear canal and lines the walls. The expansion of the bladder results from overpressure which is caused by the fact that the water is made to enter into the bladder through a tube whose diameter exeeds that of the tube through which the water leaves. The two tubes are concentric.

    Description / Table of Contents: Zusammenfassung Am Beispiel des Krankengutes der Chirurgischen Klinik rechts der Isar werden die Fortschritte in der Behandlung gefalichirurgischer Notfalle aufgezeigt. Wahrend im ersten Behandlungszeitraum (1960–1966) die Gesamtletalitat bei 43 % lag und 16% der Patienten eine Extremitat verloren, waxen die entsprechenden Prozentzahlen zwischen 1967 und 1974 12 % (Letalitat) and 6 % (Amputationsrate). Die Verbesserung der Ergebnisse wurde durch raschere Einweisung, friihere Operationsindikation und hauptsachlich durch Anwendung indirekter Operationsverfahren (Ballonkatheter, Ringstripper) erreicht.
    Notes: Summary Patients of the Surgical Department are described to illustrate the progress in the treatment of vascular emergencies. During the first period of treatment (1960–1966) 43 percent of the patients died and 16 percent lost one limb. The corresponding data for the period (1967–1974) were 12 percent mortality and a 6 percent amputation rate. The improved result are due to faster admission of patients, early decisions in favor of surgery, and, mainly, to the use of devices facilitating indirect thrombectomy and embolectomy, such as the Fogarty catheter and the ring stripper.
