Prolonged estrogen (E2) treatment prior to frozen-blastocyst transfer decreases the live birth rate.

Study Question: How does the duration of estrogen (E2) treatment prior to frozen-blastocyst transfers affect the live birth rate (LBR)?

Summary Answer: Prolonged E2 exposure as part of artificial endometrial preparation (AEP) significantly decreases the LBR after autologous frozen-thawed blastocyst transfer.

What Is Known Already: One effective method for endometrial preparation prior to frozen embryo transfer is AEP, a sequential regimen with E2 and progesterone, which aims to mimic the endocrine exposure of the endometrium in a normal cycle. Nevertheless, the optimal duration of E2 administration prior to transfer remains unknown.

MRI and Ultrasound Fusion Imaging for Cervical Cancer.

Background: Evaluating locoregional extension of cervical cancer is a key step in patient management. This study evaluated the feasibility of fusion imaging - a combination of magnetic resonance imaging (MRI) with real-time high-resolution ultrasound (US) - to diagnose cervical cancer and its extension.

Patients And Methods: This prospective bi-center study included 13 women who underwent a 1.

Vulvar Arteriovenous Malformation in a 16-Year-Old Girl.

Background: Congenital arteriovenous malformations (AVMs) are infrequent but represent a serious medical challenge because of their unpredictable progression and high hemodynamic activity.

Case: We report on the treatment of a voluminous vulvar AVM in a 16-year-old girl. After failure of medical therapy, we performed a radical surgical resection with preliminary embolization and flap reconstruction.
