Nonimmune fetal ascites: identification of ultrasound findings predictive of perinatal death.

AIM: To determine the ultrasonographic findings that predict death in fetal ascites. METHODS: This was a retrospective cohort study involving pregnancies with ultrasonographic findings related to fetal ascites. The inclusion criteria were as follows: single pregnancy with a live fetus; ultrasound findings of ascites; ascites unrelated to maternal fetal alloimmunization; and pregnancy follow-up at our institution. The χ2-test was used to evaluate the association of ultrasound findings and death. Multiple logistic regression analysis was performed to determine the ultrasound findings that are predictive of death prior to hospital discharge. RESULTS: A total of 154 pregnancies were included in the study. In 8 (5.19%) cases, ascites was an isolated finding, and in 146 cases, other alterations were observed during the ultrasound evaluation. Death before hospital discharge occurred in 117 cases (76.00%). The following ultrasonographic findings were significantly associated with death: gestational age at diagnosis <24 weeks (P<0.0001); stable/progressive ascites evolution (P=0.004); the presence of hydrops (P<0.0001); and the presence of cystic hygroma (P<0.0001). The presence of hydrops, the presence of respiratory tract malformations, and stable/progressive ascites evolution were significantly associated with the prediction of death. CONCLUSIONS: Based on ultrasound examination, the presence of hydrops, malformation of the respiratory tract, and stable/progressive evolution of ascites increase the chances of death in cases of fetal ascites.

Effect of Prenatal Counseling on Breastfeeding Rates in Mothers of Twins.

OBJECTIVE: To investigate the effect of antenatal breastfeeding counseling on the breastfeeding rates for women who give birth to twins. DESIGN: Prospective randomized trial. SETTING: Multiple Pregnancy Unit, Obstetrics Department, University of São Paulo, Brazil. PARTICIPANTS: A total of 171 mothers of twins and their 342 infants. METHODS: The participants were randomized into the prenatal counseling group (PCG) or control group (CG). Breastfeeding data were collected through personal interviews at three times after birth: 30 to 40 days (Time 1), 90 days (Time 2), and 180 days (Time 3). The primary endpoint was a comparison of the mothers' breastfeeding rates between PCG and CG in each analyzed period. The secondary endpoint was the comparison of the overall rates of twin infant breastfeeding between PCG and CG until 180 days after birth. RESULTS: The final analysis included 68 women pregnant with twins in the PCG and 60 in the CG. There was no significant difference in the breastfeeding rates between PCG and CG in the analyzed periods: Time 1 (odds ratio [OR] = 1.87, 95% confidence interval [CI] [0.71, 4.95]), Time 2 (OR = 1.50, 95% CI [0.72, 3.10]), and Time 3 (OR = 1.06, 95% CI [0.51, 2.19]). Also, no difference existed in the overall rates of breastfeeding between PCG and CG at 180 days. CONCLUSION: In women pregnant with twins, antenatal breastfeeding counseling did not significantly affect the breastfeeding rates. Further research about the best moment to counsel mothers of twins is needed to improve breastfeeding rates.

Analysis of fetal and maternal results from fetal genetic invasive procedures: an exploratory study at a University Hospital.

OBJECTIVE: To characterize the indications of pregnant women who sought the Fetal Medicine Services of the Hospital das Clínicas, at the Medical School of the Universidade de São Paulo for performing invasive diagnostic procedures, and to evaluate the results of fetal karyotypes and their pregnancies. METHODS: A retrospective and observational study on pregnant women who underwent chorionic villus sampling (CVS), amniocentesis, and cordocentesis in the period from February, 2005 to December, 2009. Other diagnostic or therapeutic procedures were not included. The result of pregnancy was obtained by consulting patient electronic records, medical records, and/or telephone call. RESULTS: 713 procedures were performed (113 CVS, 340 amniocenteses, and 260 cordocenteses). The main indication for performing invasive procedures was the presence of structural changes in fetuses, followed by increased values of nuchal translucency, and advanced maternal age. Fetal karyotype was altered in 186 cases (26.1%). The 18 trisomy was the commonest aneuploidy followed by the 21 trisomy, X monosomy, and 13 trisomy. There were 4.9% cases of miscarriage, 25.7% cases of stillborn infants, and 13% cases of neonatal deaths. Eight pregnant women opted for legally induced abortion. 99% of pregnant women whose fetuses did not present abnormalities and presented normal fetal karyotype had infants who were born alive.
