Massive Fetomaternal Hemorrhage Caused by an Intraplacental Choriocarcinoma: Case Report and Review of the Literature.

Intraplacental choriocarcinoma (IC) is a gestational trophoblastic neoplasia located within the placenta. Due to its silent presentation, more than half of the cases are diagnosed incidentally. An association with fetomaternal hemorrhage (FMH), stillbirth, and intrauterine growth restriction has been found.

Real Time PCR and Culture-Based Virus Isolation Test in Clinically Recovered Patients: Is the Subject Still Infectious for SARS-CoV2?

Background: The highly variable manifestation of the COVID-19 disease, from completely asymptomatic to fatal, is both a clinical and a public health issue. The criteria for discharge of hospitalized patients have been based so far on the negative result of Real-Time Reverse Transcriptase Polymerase Chain Reaction (RT-PCR) tests, but the persistence of viral fragments may exceed that of the integral virus by weeks. The aim of our study was to verify the clearance of the virus at viral culture in patients hospitalized for COVID-19 that have clinically recovered but are still positive on nasopharyngeal swab.
