Zusammenfassung

Der Geburtsmechanismus wird durch die Größe und Form des knöchernen Beckens, die Größe des kindlichen Kopfes, die Kraft der uterinen Kontraktionen, die Verformbarkeit des kindlichen Kopfes, und die Haltung und Einstellung des kindlichen Kopfes bestimmt. Mittels Pelvimetrie durch Magnetresonanztomographie (MRT) oder Sonographie kann das knöcherne Becken beurteilt werden, um ein Kopf-Becken-Missverhältnis auszuschließen. Ein sonographisch gemessener vergrößerter Kopfumfang kann sich insbesondere bei Nulliparität auf den Geburtsmodus auswirken. Die Kopfverformung führt zu einem reduzierten Kopfumfang und erhöht so die Chancen für eine erfolgreiche vaginale Entbindung. Die Überlappung der Schädelnähte kann sonographisch dargestellt werden. Die sonographisch bestimmte Kopfhaltung und -einstellung ist verlässlicher als deren digitale Bestimmung. Voraussetzung für eine vaginal-operative Entbindung ist neben der Kopfeinstellung die exakte Beurteilung des fetalen Höhenstandes. Es sind mehrere sonographische Methoden zur Höhenstandbestimmung beschrieben. In Zukunft werden Geburtsabläufe durch die MRT virtuell simuliert werden können. Der Einsatz der Bildgebung sub partu ermöglicht eine sichere Geburtsmedizin.

Mehr Lebenszeit mit Abemaciclib bei fortgeschrittenem Brustkrebs?

24.05.2024 Mammakarzinom Nachrichten

In der MONARCHE-3-Studie lebten Frauen mit fortgeschrittenem Hormonrezeptor-positivem, HER2-negativem Brustkrebs länger, wenn sie zusätzlich zu einem nicht steroidalen Aromatasehemmer mit Abemaciclib behandelt wurden; allerdings verfehlte der numerische Zugewinn die statistische Signifikanz.

Blutdrucksenkung könnte Uterusmyome verhindern

Frauen mit unbehandelter oder neu auftretender Hypertonie haben ein deutlich erhöhtes Risiko für Uterusmyome. Eine Therapie mit Antihypertensiva geht hingegen mit einer verringerten Inzidenz der gutartigen Tumoren einher.

„Übersichtlicher Wegweiser“: Lauterbachs umstrittener Klinik-Atlas ist online

17.05.2024 Klinik aktuell Nachrichten

Sie sei „ethisch geboten“, meint Gesundheitsminister Karl Lauterbach: mehr Transparenz über die Qualität von Klinikbehandlungen. Um sie abzubilden, lässt er gegen den Widerstand vieler Länder einen virtuellen Klinik-Atlas freischalten.

Antikörper-Wirkstoff-Konjugat hält solide Tumoren in Schach

16.05.2024 Zielgerichtete Therapie Nachrichten

Trastuzumab deruxtecan scheint auch jenseits von Lungenkrebs gut gegen solide Tumoren mit HER2-Mutationen zu wirken. Dafür sprechen die Daten einer offenen Pan-Tumor-Studie.
