Perinatal asphyxia is a general term referring to neonatal encephalopathy related to events during birth. Asphyxia refers to a deprivation of oxygen for a duration sufficient to cause neurologic injury. Most cases of perinatal asphyxia are not necessarily caused by intrapartum events but rather associated with underlying chronic maternal or fetal conditions. Of intrapartum causes, obstetric emergencies are the most common and are not always preventable. Screening high-risk pregnancies with ultrasound, Doppler velocimetry, and antenatal testing can aid in identifying fetuses at risk...

A velamentous umbilical cord is characterized by membranous umbilical vessels at the placental insertion site that are prone to compression and rupture, especially when they are located in the membranes covering the cervical os (vasa praevia). The velamentous insertion of the umbilical cord, with a reported incidence of 1% in singleton pregnancies and 15% in monochorionic twin gestations, has been associated with obstetric complications: fetal growth restriction, prematurity, congenital anomalies, low Apgar scores, fetal bleeding with acute fetal distress and placental retention...

INTRODUCTION: According to the WHO, miscarriage is defined as "the loss of a pregnancy before the age of 20 weeks of gestation or fetal weight below 500 g". Only 50-60% of all conceptions fail to survive 20 weeks of gestation. It is estimated that about 75% of all unsuccessful conceptions are due to failed implantation and are not reported as spontaneous abortions. MATERIAL AND METHODS: We performed a prospective observational study at the Department of Obstetrics and Gynecology of the Medical University Plovdiv between October 2014 and September 2015...

Systemic autoimmune diseases especially affect young women during childbearing age. The aim of this review is to update systemic lupus erythematosus, antiphospholipid syndrome and systemic sclerosis management during pregnancy. These diseases present variable maternal and fetal risks. Studies show that an appropriate disease control and a reasonable remission period prior to pregnancy are associated with satisfactory obstetric outcomes. Antiphospholipid autoantibodies profile, anti-Ro/anti-La antibodies, pulmonary pressure and activity evaluation are crucial to assess the pregnancy risk...
