OBJECTIVE It is known from animal experiments that blood flow through the ductus venosus changes with fetal strain. Therefore the ratio of umbilical vein to ductus venosus flow rate in human intrauterine growth retardation and multifetal pregnancies was investigated and compared with that in control subjects. STUDY DESIGN Blood flow rates in the umbilical vein and in the ductus venosus, as we...

Abstract Background Thrombocytopenia is the most common hematological abnormality which is encountered in the neonatal intensive care unit (NICU). The incidence in neonates varies greatly, depending upon the population studies. According to the frequency of thrombocytopenia and its complications and because of lack of such research in Iran, this study was performed on neonates admitted to Sha...

Intrauterine growth restriction (IUGR) is defined as fetal growth less than the normal growth potential of a specific infant because of genetic or environmental factors. The terms IUGR and Small for Gestational Age (SGA) are often used alternatively to describe the same problem, although there exists subtle differences between the two. The burden of IUGR is concentrated mainly in Asia which acc...

A policy of expectant management until 32 weeks of gestation in 29 dichorionic pregnancies discordant for growth retardation resulted in an overall mortality of 24% (95% CI 13.9-37.2%) and a handicap of 2.2% (95% CI 0-12.0%). None of the normally grown co-twins died or was handicapped as a result of iatrogenic prematurity.

Fetal growth retardation is a fetal adaptation in response to inadequate supply of oxygen and/or nutrients. Animal models of intrauterine growth retardation are an invaluable tool to question the genetic, molecular and cellular events that determine fetal growth and development. Rodent and non-litter bearing animals are mammalian system with similar embryology,anatomy and physiology to humans. ...

Some, albeit not all studies on the relationship between intrauterine growth retardation (IUGR) and female pubertal development have found an earlier and rapidly progressing puberty as well as concomitant disorders of related functional systems such as polycystic ovary syndrome and short stature. These pubertal changes are part of a growing list of IUGR-related diseases, which includes non-insu...
