Zusammenfassung

Nachdem schon eine einfache Verdickung des Urothels genetische Veränderungen zeigen kann, die denen papillärer differenzierter Urothelkarzinome entsprechen, ist es nicht leicht, präkanzeröse Urothelveränderungen rein morphologisch eindeutig zu erkennen. Immunhistochemische und molekulare Zusatzmethoden unterstützen das differenzierte Erkennen und helfen insbesondere, die klinisch wichtige, genetisch instabile Zelle als Merkmal des Carcinoma in situ (CIS) zu diagnostizieren. Die klinische Bedeutung der vielfältigen morphologischen Erscheinungsformen, die vom großzelligen bis mikropapillären CIS reichen, ist bislang wenig untersucht. Wichtig, nicht zuletzt im Hinblick auf ein besseres Verständnis der möglichen Sonderformen des Harnblasenkarzinoms (Adeno- und Plattenepithelkarzinome), scheint es zudem, die nicht-urothelialen Veränderungen des Urothels wie die intestinale Metaplasie und Plattenepithelmetaplasie hinsichtlich der phänotypischen und molekularen Eigenschaften besser zu definieren.

Phytotherapie als Basis bei der Behandlung von PMS

Die Symptome beim Prämenstruellen Syndrom (PMS) sind vielfältig und erfordern eine differenzierte Behandlung. Welche Rolle spielen Phytopharmaka in der gynäkologischen Praxis? Und welche neuen Erkenntnisse sind für die Klinik besonders interessant? Darüber sprechen Dr. Dorothee Struck und Prof. Dr. Petra Stute im Video.

Zentraler Therapiebaustein in Praxis und Klinik

Sonderbericht

Weltweit leidet etwa die Hälfte aller Frauen im gebärfähigen Alter an Symptomen eines prämenstruellen Syndroms (PMS). An Diagnose und Therapie des PMS sind sowohl Gynäkologinnen und Gynäkologen in der Niederlassung als auch in Kliniken beteiligt. Die Wahl einer geeigneten Behandlung hängt von den vorherrschenden PMS-Symptomen, der Familienplanung, möglichen Risikofaktoren und Komorbiditäten sowie den Präferenzen der betroffenen Frau ab.

Ein Drittel aller menstruierender Frauen hat mit prämenstruellen Beschwerden zu kämpfen. Um Symptome, wie sie beim PMS auftreten, nicht nur symptomatisch zu therapieren, können pflanzliche Präparate mit Mönchspfefferextrakt nachhaltig helfen. Erfahren Sie mehr zur Studienlage und dem Wirkmechanismus.
