Excerpt

It has been over two decades since the first preimplantation genetic diagnosis (PGD) for a monogenic disorder was performed [1], and methods have evolved to include a wide variety of techniques [2]. Among the most important advances was the incorporation of genotyping of linked informative markers near the mutation in order to avoid misdiagnosis from a phenomenon known as allele drop out (ADO). ADO occurs when two alleles are present, but the PCR-based test only detects one of the two, which can result in misdiagnosis of a monogenic disorder. However, by evaluating nearby linked informative polymorphisms, this type of error can be avoided since it is less likely to occur twice in the same test [2, 3]. …

Hirsutismus bei PCOS: Laser- und Lichttherapien helfen

26.04.2024 Hirsutismus Nachrichten

Laser- und Lichtbehandlungen können bei Frauen mit polyzystischem Ovarialsyndrom (PCOS) den übermäßigen Haarwuchs verringern und das Wohlbefinden verbessern – bei alleiniger Anwendung oder in Kombination mit Medikamenten.

ICI-Therapie in der Schwangerschaft wird gut toleriert

Müssen sich Schwangere einer Krebstherapie unterziehen, rufen Immuncheckpointinhibitoren offenbar nicht mehr unerwünschte Wirkungen hervor als andere Mittel gegen Krebs.

Weniger postpartale Depressionen nach Esketamin-Einmalgabe

Bislang gibt es kein Medikament zur Prävention von Wochenbettdepressionen. Das Injektionsanästhetikum Esketamin könnte womöglich diese Lücke füllen.

Bei RSV-Impfung vor 60. Lebensjahr über Off-Label-Gebrauch aufklären!
