    Title Association of Maternal Serum Alpha-fetoprotein with Persistent Placenta Previa.
    Date February 2005
    Journal The Journal of Maternal-fetal & Neonatal Medicine : the Official Journal of the European Association of Perinatal Medicine, the Federation of Asia and Oceania Perinatal Societies, the International Society of Perinatal Obstetricians
    Excerpt

    OBJECTIVE: To evaluate the relationship between maternal serum alpha-fetoprotein (MSAFP) and the risk of persistent placenta previa. METHODS: We conducted a retrospective cohort study of singleton pregnancies with sonographic evidence of placenta previa at 15-20 weeks' gestation, between October 1991 and August 2000. Only pregnancies with MSAFP determination at 15-20 weeks' gestation and non-anomalous live-born infants > or =24 weeks' gestation were included. Pregnancies in which Cesarean delivery was performed for placenta previa were considered persistent; this was the primary outcome. RESULTS: Of 275 women with previa at 15-20 weeks' gestation, 33 (12%) had previa at delivery. Trend analysis revealed a greater likelihood of persistent previa with increasing MSAFP values (p=0.01). Mid-trimester MSAFP <1 multiple of the median (MoM) was associated with a decreased incidence of persistence of 4%, significantly less than the risk at > or =1 MoM (16%; p=0.01). CONCLUSIONS: There is an association between increasing MSAFP values and greater likelihood of persistent placenta previa. An MSAFP value <1 MoM is associated with a reduction in the risk of persistence of previa to delivery.

    Title Recurrence of Mild Malformations and Dysplasias.
    Date August 2003
    Journal Obstetrics and Gynecology
    Excerpt

    OBJECTIVE: To estimate whether women delivering infants with mild malformations are at increased risk to have a subsequent infant with a mild malformation. METHODS: Both severe and mild malformations detected at birth were cataloged prospectively for 33,701 women with two consecutive singleton births of infants weighing 500 g or more at a tertiary care hospital. Records from a total of 67,402 infants were analyzed from January 1, 1988, through December 31, 2000. Mild malformations and dysplasias were defined to include skin lesions (eg, café au lait spots, nevi, and hemangiomas), extra nipples, and abnormalities involving digits. Pearson and McNemar chi(2) statistics and analysis of variance were used for statistical analysis. Estimation of recurrence risks was accomplished using standard methods for rates and proportions. RESULTS: Of the study women, 2.7% delivered infants with mild malformations in their index pregnancy. Mild malformations recurred in 7% of women whose index infant had a mild malformation (2.7% versus 7%, P <.001). Mild malformations involving the skin or digits also significantly increased in the next delivery (2% versus 5%, P <.001; 0.5% versus 8%, P <.001; recurrence of skin and digit anomalies, respectively). CONCLUSION: Women delivering infants with mild malformations involving the skin and digits of the infant are at increased risk for recurrence during their next pregnancy.
