    Das elektrophysiologische Verhalten gesunder und glaukomkranker menschlicher Augen bei kurzzeitiger intraocularer Druckbelastung (1975)

    Description / Table of Contents: Zusammenfassung Bei 8 normalen und bei 8 glaukomkranken Augen wurde der Augeninnendruck 80 sec lang auf P m=(P d+P s)/2 erhöht und gleichzeitig ein ERG und ein VER abgeleitet. Dabei zeigten sich im ERG keine signifikanten Unterschiede zwischen an Glaucoma simplex erkrankten und normalen Augen. Dagegen war die Änderung des VER bei glaukomkranken Augen wesentlich stärker ausgeprägt als bei gesunden Augen. Dieses unterschiedliche Verhalten im VER wird auf die erhöhte Druckempfindlichkeit des praelaminaren Sehnervenabschnittes bei Glaukomaugen zurückgeführt. Mit dieser Methode scheint eine objektive Bestimmung der Drucktoleranz der Papille möglich.
    Notes: Summary An electrophysiological study has been done on glaucomatous and normal eyes with briefly elevated intraocular pressure. There was no significant difference between the ERGs, but the changes in the VERs of glaucomatous eyes differed widely from those of normal eyes. This seems to be due to the high sensitivity to pressure of the prelaminary part of the optic nerve in glaucomatous eyes. Obviously this could be a method for the objective measurement of the sensitivity of the papillary vessels to raised intraocular pressure.

    Description / Table of Contents: Zusammenfassung Die Wiederherstellung der weiblichen Brustform nach Brustamputation verbessert deutlich die psychische Situation der betroffenen Frauen. Für die Rekonstruktion stehen verschiedene Methoden zur Verfügung: lokale Hautlappen oder myocutane Lappenplastiken nach querer Mastektomie, subcutane oder subpectorale Prothesenimplantation oder Coriumplastik nach subcutaner Mastektomie. 62 von 83 Frauen, bei denen 1976–1982 nach einer dieser Methoden eine Brustrekonstruktion durchgeführt worden war, wurden 1982 nachuntersucht. Die Probleme und Komplikationen der Brustrekonstruktion werden kritisch analysiert.
    Notes: Summary Reconstruction of the female breast after mastectomy clearly improves the psychic situation of the woman. Several methods are available for breast reconstruction: local or myocutaneous flap techniques after radical mastectomy, subcutaneous or subpectoral implantation of prosthesis or coriumplasty after subcutaneous mastectomy. Of 83 females who underwent breast reconstruction by one of these methods between 1976 and 1982, 62 were checked up in 1982. The problems and complications of breast reconstruction were critically analysed.

    Scar formation and areola sensation after aesthetic breast surgery (1990)
    Springer
    European journal of plastic surgery 13 (1990), S. 153-155

    ISSN: 1435-0130
    Keywords: Reduction mammaplasty ; Mastopexy ; Scar formation ; Areaola sensation

    Notes: Summary 105 patients were examined one to fifteen years after reduction mammaplasty or mastopexy. The technique of McKissock, Strömbeck and Pitanguy had been used. The appearance of the scars, the width of the scars and the sensation of the areola in the three different methods of operative treatment were compared. The study showed that hypertrophy of the scars and areola sensation do not depend on the type of operative technique. However, as expected the width of the scars is significantly greater in case of reduction mammaplasty compared to mastopexy.

    Secondary operations after replantations (1980)
    Springer
    European journal of plastic surgery 5 (1980), S. 235-241

    ISSN: 1435-0130
    Keywords: Replantation ; Secondary operations
    Source: Springer Online Journal Archives 1860-2000
    Topics: Medicine
    Notes: Summary 77 Secondary operations after 72 replantations of completely amputated parts of the body in 54 patients are analysed. These operations have been carried out over a period of five years from 1974 to 1979 at the Department of Plastic and Reconstructive Surgery of the 2nd Surgical University Hospital of Vienna. In assessing the distribution of secondary operations after replantations a distinction between early and late secondary operations is of considerable value. This paper presents a survey of the operations performed as well as two significant cases with several secondary surgical interventions.

    Die Änderung der elektrophysiologischen Antwort am menschlichen Auge bei kurzzeitiger Erhöhung des intraokularen Druckes (1974)

    Description / Table of Contents: Zusammenfassung Bei 14 gesunden Versuchspersonen wurden nach einer Erhöhung des Augeninnendruckes mittels eines Federdruckdynamometers nach Müller gleichzeitig ein ERG und die visuell evozierte Antwort (visual evoked response=VER) abgenommen. Die Druckbelastung erfolgte stufenweise und betrug jeweils 80 sec. Ihre Höhe wurde in Beziehung zum Blutdruck der Arteria ophthalmica gesetzt und reichte von knapp unter ihrem diastolischen Druck bis knapp unter ihren systolischen Druck. Im ERG zeigten sich die ersten Veränderungen knapp unter dem diastolischen Ophthalmicablutdruck und betrafen sowohl die a-Welle als auch die b-Welle. Bei einem Druck von Pd + 70% wurde das Maximum der Amplitudenabnahme erreicht. Sie betrug bei der a-Welle 30%, bei der b-Welle 65% gegenüber dem ohne Druckbelastung gewonnenen Ausgangswert. Die visuell evozierte Antwort änderte sich ab Pd + 20% und erlosch bei Pd + 90% praktisch vollkommen. Dieses unterschiedliche Verhalten der Antworten des VER und ERG bei Erhöhung des intraokularen Druckes wird mit den Besonderheiten der Gefäßversorgung der für die Entstehung der elektrischen Potentiale verantwortlichen Gewebe erklärt. Dabei wird angenommen, daß mit dem VER vorwiegend eine anoxämische Schädigung der Ganglienzellen und ihrer Fortsätze bis zur Lamina cribrosa, mit der b-Welle eine Schädigung der inneren Körnerschichte und mit der a-Welle eine Schädingung der Rezeptorenschichte erfaßt werden kann.
    Notes: Summary VER and ERG readings were taken from 14 healthy test-persons after the intraocular pressure had been increased using a Müller spring-pressure dynamometer. The pressure elevated stepwise and applied for 80 sec each step, was set in relation to the blood pressure in the arteria ophthalmica. It reached from a value just approaching the artery's diastolic pressure to that just under its systolic pressure. The first ERG changes involving the a-wave as well as the b-wave were evident just below the ophtalmica-diastolic pressure. Maximum amplitude reductions of 30% and 65% for the a- and b-wave respectively, were achieved at diastolic pressure +70% when compared to test values acquired without application of pressure. Changes in the visual responses on the other hand were noticed beginning at diastolic pressure +20% and the amplitudes were practically non existent at diastolic pressure +90%. The disparrity in ERG and VER responses to pressure changes can possibly be explained by differences in the pressure sensitivities of the vessels supplying the presumed origins of the electrical potentials, as well as differences in the sensitivities to anoxia of the tissues composing these sites. It is presumed that the VER-changes represent anoxemic changes in the neurons of the ganglion-cell layer and their axons up to the lamina cribrosa whereas the b-wave of the ERG responds to damage in the minor nuclear layer, and the a-wave to that in the receptor cell layer.
