    This report investigates the effect of chorioamnionitis on infant mental and psychomotor development at one year through the prospective study of 698 preterm pregnancies complicated by premature rupture of membranes and managed expectantly without antenatal corticosteroids or tocolytic agents. Ninety-two mothers (13%) developed chorioamnionitis, resulting in a statistically significant increase in neonatal mortality (25 versus 6%), respiratory distress syndrome (RDS) (62 versus 35%), intraventricular hemorrhage (56 versus 22%), and sepsis (28 versus 11%). A multidisciplinary team examined 43 surviving infants at corrected one year of life and measured their mental and psychomotor development by the Bayley scales. No statistically significant difference in outcomes was observed when their development was compared with that of a control group matched for birth weight, gestational age, severity of intraventricular hemorrhage, and severity of RDS.

    Teratogenicity01:07

    Teratogenicity

    The ability of a drug to produce structural deformations and functional abnormalities in the developing embryo or the fetus is called teratogenicity, and the drug producing this effect is known as a teratogen. Teratogenic effects include stillbirth, miscarriage, intrauterine growth restriction, and neurocognitive delay. A teratogen may affect the embryo at different stages of development, which is important in determining the type and extent of the damage. During blastocyst formation, the early...

    Development of the Oral Microbiota

    The establishment of the oral microbiome begins before birth, challenging the long-held belief that the fetal oral cavity is sterile. The presence of oral microbes such as Streptococcus and Fusobacterium in amniotic fluid suggests that microbial exposure may occur in utero, potentially through translocation from the maternal oral or gastrointestinal tract. This early colonization primes the neonatal immune system and sets the stage for subsequent microbial succession. Maternal health,...
