In order to evaluate the influence of the time interval on the second twin in twin deliveries, we have used more precise criteria than have been used in the literature to date. The following parameters of the twins were analyzed: normal CTG of the second twin recorded continuously during labor and pH value of the umbilical artery blood after delivery as well as clinical state according to the m...

F AMILY RELATIONSHIPS, especially the disruptive potential of libidinal and aggressive drives within the nuclear family, are among the most common themes of mythology. The theme of twinship in mythology can be seen as the focus of real and projected psychological tensions and their imagined or preferred solutions. Mythological fascination with twins and twinship and some parallels between ancie...

Although advances in neonatal care over the past century have resulted in increased rates of survival among at-risk births, including infants with low birth weight, we have much to learn about psychological outcomes in this population. In particular, despite growing evidence that low birth weight may be associated with an increased risk for Attention-Deficit/Hyperactive Disorder (ADHD) symptoms...

BACKGROUND Most twins after assisted reproductive technology (ART) are dizygotic. Analysis of dizygotic twin pairs is useful in assessing familial aggregation in the development of birth defects. METHODS Using nationwide post-ART data from the Japan Society of Obstetrics and Gynecology, recurrence risk ratios (RRRs)-defined as probandwise concordance rates of birth defects in twins divided by...

Objective. To investigate whether the perinatal risks associated with early vanishing twin (VT) syndrome differ between cleavage- or blastocyst-stage embryo transfers (ET) in fresh in vitro fertilization (IVF) cycles. Methods. Retrospective, single-center, cohort study of IVF cycles with fresh cleavage- or blastocyst-stage ETs resulting in a live singleton birth. The incidence of preterm birth ...

This paper represents another important piece of the puzzle that is sonographic cervical length measurement for the prediction of preterm birth. Cervical length is now well established as a predictor of preterm birth in both twin and singleton populations in asymptomatic women, a fact that has grown in clinical relevance, with data suggesting that perhaps in both populations, but certainly in s...
