Background and objetive On January 7th, 2020, a new coronavirus, SARS-CoV-2, was identified, as responsible for a new human disease: COVID-19. Given its recent appearance, our current knowledge about the possible influence that this disease can exert on pregnancy is very limited. One of the unknowns to be solved is whether there is a vertical transmission of the infection during pregnancy. Patients and methods Using the Real-time Polymerase Chain Reaction techniques for SARS-CoV-2 nucleic acids, the possible presence of this germ in vaginal discharge and amniotic fluid was investigated in four pregnant Caucasian patients affected by mild acute symptoms of COVID-19 during the second trimester of pregnancy. Results There is no laboratory evidence to suggest a possible passage of SARS-CoV-2 from the infected mother to the amniotic fluid. Conclusions It is necessary to expand the investigation of COVID-19 cases diagnosed during pregnancy to clarify the real influence that SARS-CoV-2 has on pregnant women and their offspring, as well as those factors that modulate the disease.

Puerperal Uterine Inversion (PUI) is a rare but potentially life-threatening delivery complication in which the uterine fundus collapses within the endometrial cavity. This "glove-finger" introflexion of uterine walls generally occurs as an immediate postpartum complication and is responsible of different degrees of vaginal bleeding, shock and hypogastric pain that can cause serious maternal complications, including death. There are few reports of recurrent postpartum uterine inversion like the one we present here, and its causes remain unclear. Early diagnosis of this complication is crucial as it is the only one measure that can allow a successful and conservative treatment: an inverse relationship between the time that uterus keeps inverted and the probability of repositioning has been firmly established. This case report describes the exceptional and innovative use of the SOS Bakri ® balloon (Cook Medical Incorporated) in the management of a recurrent puerperal uterine inversion. To our knowledge it is one of the first reports in the world of this procedure, perhaps the second one after Soleymani's et al description; and the first one in a third degree recurrent puerperal uterine inversion.
