The effects of valproic acid on early pregnancy human placentas: Pilot ex vivo analysis in cultured placental villi.

Valproic acid is an established structural and neurodevelopmental teratogen. Recently, we demonstrated that valproate alters the barrier function of perfused term human placentas. Here, we conducted a pilot study to evaluate the effects of subchronic valproate exposure on carrier expression in cultured placental villous explants from early human pregnancies.

Intrapartum antibiotics and childhood atopic dermatitis.

Introduction: Atopic dermatitis (AD) in children significantly impacts families because of medical costs, "lost" hours, and secondary characteristics such as asthma and ancillary infections. We investigate whether children delivered vaginally to women receiving intrapartum antibiotics have a greater risk of AD when younger than the age of 2 years than their counterparts.

Methods: We conducted a retrospective analysis of women who delivered child(ren) vaginally between 1996 and 2008.
