The results of the International Collaborative Study of Maternal phenylketonuria have shown that dietary phenylalanine restriction of women with hyperphenylalaninemia during pregnancy decreases the incidence of mental retardation, microcephaly, congenital heart disease, and intrauterine growth retardation in their offspring. The best results are achieved when treatment is initiated before conce...

The purpose of this study was to characterize the sleep patterns of children with intrauterine growth retardation, known to be at risk for neurodevelopmental disorders, and seek a possible correlation with behavior, concentration, and attention problems. The sleep patterns of 26 children with intrauterine growth retardation aged 4 to 7 years were compared with those of 47 control children using...

Perturbations of the maternal environment involve an abnormal intrauterine milieu for the developing fetus. The altered fuel supply (depends on substrate availability, placental transport of nutrients and uteroplacental blood flow) from mother to fetus induces alterations in the development of the fetal endocrine pancreas and adaptations of the fetal metabolism to the altered intrauterine envir...

The fetal risk in maternal diabetes mellitus is high [5, 6]. The reasons for fetal macrosomatia are controversially as are those for intrauterine fetal growth retardation and intrauterine fetal death. These mostly happen without prodromes and are feared by all obstetricians. Morphologists have described signs of a so-called chronic placental insufficiency in cases of small for date infants and ...

Growth failure is cumulative, and short stature is associated with multiple indices of reduced human capital. Few studies have been able to address in a single analysis both consideration of the timing of growth failure and comparison across populations. We analyzed data from birth cohorts in Brazil, Guatemala, India, the Philippines, and South Africa (n = 4,659). We used data on length at birt...
