    Notes: Lateral inhomogeneities generate fluctuations in the traveltime of seismic waves. By evaluation of these traveltime fluctuations from different source and receiver positions, lateral inhomogeneities can be located using a pseudo inverse matrix method (Aki, Christoffersson and Husebye 1977). The formulation of the problem is possible for transmitted waves as well as for reflected and refracted waves. In reflection seismics this method is of importance, if no reflections from the inhomogeneities themselves, but only reflections from lower boundaries can be observed.The basic assumptions for the mathematical formulation are (1) the average velocities and depths of the reflecting horizons are known already from standard processing methods, and (2) the traveltime residuals are due to lateral velocity changes between different reflectors or between reflectors and the surface. The area of the earth to be considered is divided into layers and the layers into rectangular blocks. The parallel displacement of a ray after passing a disturbed block is neglected, only the traveltime residual is taken into account.In this paper the method and its application to data obtained with two-dimensional models are described.

    Notes: Summary Anaesthesia in guinea pigs with a new highly potent and shortacting analgesic, carfentanyl (R 33799), combined with the hypnotic, etomidat (R 26490), is reported. Clinical observations as well as respiratory and circulatory variables have revealed this combination to be safe. Profound surgical anaesthesia has been obtained with good sedation, analgesia, and immobilisation. This method has been evaluated clinically and can be recommended with confidence in this species.

    Notes: Abstract Wegener's granulomatosis (WG) is a rare disease in pediatric patients. The case of a 14-year-old girl with generalized WG is described and the pediatric literature reviewed. Thirty additional cases of WG in childhood have been traced in previous studies. Diagnostic problems are discussed in the context of clinical, radiological and biopsy findings.

    Description / Table of Contents: Zusammenfassung Bei 7 Patienten (Durchschnittsalter 42 Jahre) mit Rhythmusstörungen verschiedener Form wurden mit Hilfe der Myokardszintigraphie Verteilungsstörungen der myokardialen Perfusion bei im Koronarogramm unauffälligen extramuralen Koronargefäßen nachgewiesen. Die Defekte waren zum Teil umschrieben, zum Teil diffus. Bei 2 Patienten mit einem Linksschenkelblock projizierte sich die Perfusionsverteilungsstörung auf den oberen Teil des Septum interventriculare. Ein Zusammenhang zwischen der Topographie des Perfusionsdefektes und der Form der elektrophysiologischen Abnormität erscheint bei diesen Patienten wahrscheinlich. Als Ätiologie der myokardialen Perfusionsstörung kann bei einem der Patienten ein Zustand nach Myokarditis mit narbiger Ausheilung angenommen werden. Bei den anderen 6 Patienten muß die Ursache der Perfusionsstörung offen bleiben. Das Vorliegen einer „small vessel disease“ muß diskutiert werden. Die Untersuchungen weisen auf einen Zusammenhang zwischen Störungen im Bereich der Mikrozirkulation und Arrhythmien bei jüngeren Patienten hin.
    Notes: Summary In 7 patients with arrhythmias of various origin the myocardial scintigram displayed either a diffuse or circumscript defect of the perfusion. The coronary arteriogram was normal in all patients. The localized defect of the perfusion in 2 patients was in the region of the upper part of the interventricular septum. Both had a left bundle brunch block. A correlation between the perfusion defect and the electrophysiological abnormality seems probable. The perfusion defect in one of the patients is most probably caused by a previous myocarditis followed by fibrous changes. In the other 6 patients the cause for the perfusion defect is not obvious. A history of myocarditis is missing. The presence of “small vessel disease” in those patients has however to be considered. Our results point to the relation between an abnormality of the microcirculation and arrhythmias in younger patients.

    A detailed comparison of theoretical wave spectra and wave forecasting methods (1957)

    Notes: Conclusion The status of various results on the determination of the appropriate family of theoretical wave spectra to describe wind generated seas and the status of various wave forecasting methods have been reviewed. The spectra of Neumann appear to describe the sea more accurately than other theoretical spectra and the wave forecasting methods of Pierson, Neumann and James appear to be the most nearly correct for the widest variety of possible wave and weather situations.

    Description / Table of Contents: Zusammenfassung An 18 Beagles wurde der Halsoesophagus durch ein freies, autologes Jejunumtransplantat ersetzt. Interponatsnekrosen durch Thrombosen an den Gefäßanastomosen kamen wegen der mikrochirurgischen Technik nicht vor. Die Passage und Peristaltik blieb in allen Fällen erhalten. Viermal schrumpfte das Interponat durch periluminäre Narben. Zu einer Fibrosicrung des Interponates selbst kam es nicht, die Ganglienzellen des Plexus myentericus sind auch nach 1 Jahr noch erhalten. Es handelt sich somit um ein risikoarmes Verfahren zum Ersatz der Halsspeiseröhre.
    Notes: Summary Within a collective of 18 Beagles the proximal part of the esophagus was replaced by a free autologous jejunum interponate. Because of microvascular anastomosis a necrosis of the interposed jejunum was prevented. Passage and peristalsis were maintained in all cases. In four cases shrinking at the interponate caused by periluminar scar formation are observed. No fibrosis developed, the gangliocytes of the plexus myentericus remained viable. With this technique, we are on the way to an esophagus replacement of lower risk.

    Notes: Summary Computerized tomography of the posterior cranial fossa and the cerebellopontine angle facilitates the identification of lesions 1–1,5 cm in size using i.v. contrast material. After lumbar puncture and injection of 5–6 ml of air it is possible to detect tumors less than 1 cm in diameter and observe the nerves within the cerebellopontine angle cistern and internal auditory canal. The procedure causes only mild or moderate discomfort.

    Notes: Summary A common observation during otologic surgery under general anesthesia, notably with nitrous oxide, is tympanic membrane graft displacement due to elevated intratympanic pressure. We mean that nitrous oxide increases the intratympanic pressure. We measured the intratympanic pressure changes with the Madsen impedance measuring instrument ZO 73. The results of the measurements of 84 ears are discussed and the tendencies of the connection between pressure in the middle ear and the size of the mastoid bone are shown.
