Birth of monozygotic dichorionic twins after a single blastocyst embryo transfer: a case report of genetic determination of zygosity.

Objective: To report a case of monozygotic dichorionic (DC) twins after a single cryopreserved blastocyst embryo transfer followed by genetic determination of zygosity postpartum.

Design: Case report.

Setting: University hospital.

Analgesic efficacy of remifentanil patient-controlled analgesia versus combined spinal-epidural technique in multiparous women during labour.

Objectives: To compare the analgesic profile of remifentanil patient-controlled analgesia (RPCA) and combined spinal-epidural analgesia technique (CSEA) in multiparous women during the entire labour. We hypothesized that CSEA would provide a better and more sustained pain reduction than RPCA.

Material And Methods: A prospective observational trial under ID NCT02963337 at a university hospital in Slovenia 2017-2018.
