RESUMEN
Rh alloimmunization remains a potentially devastating complication of pregnancy, with fetal anemia causing hydrops and intrauterine death. Intrauterine transfusion is the standard treatment, but is particularly dangerous before 20 weeks gestation. When the need for intrauterine transfusion is anticipated early in pregnancy, immune-modulating therapies such as plasmapheresis and IVIG have been used to delay transfusion to a later gestational age. We report a 35-year-old G5P1 Rh(D)-negative woman with severe Rh alloimmunization managed successfully with sequential plasmapheresis, intravenous immune globulin and intrauterine transfusion. The optimal plasmapheresis treatment protocol and incremental benefit of IVIG remains unknown.

INTRODUCTION: This study was undertaken to assess the influence of labor and cesarean section on endothelial function. MATERIALS AND METHODS: Flow-mediated vasodilatation (FMD) was measured before and after delivery for an assessment of endothelial function in three groups: (1) the Vaginal delivery group (with spontaneous labor or induction of labor, n = 48), (2) the Elective C/S group (with a cesarean planned, n = 20), and (3) the C/S after FP group (scheduled for vaginal delivery but required to have an emergency cesarean section because of failure in progress, n = 11). RESULTS: There were statistically significant changes between the antepartum and postpartum FMD values in the Vaginal delivery group and the Elective C/S group but not in the C/S after FP group (P < 0.001, P = 0.023 and P = 0.22 respectively). CONCLUSIONS: These observations suggest that labor may enhance endothelial function and that cesarean section may impair endothelial function.

OBJECTIVE: The Ritscher-Schinzel syndrome (RSS), also known as the 3C syndrome, is an autosomal recessive disorder classically comprising craniofacial, cerebellar and cardiac defects. The underlying molecular etiology remains unknown; therefore, prenatal diagnosis of recurrences depends on identification of the associated structural anomalies on second trimester ultrasound examination. Identification of recurrences using first-trimester ultrasound has not been reported previously. METHODS: Two women who presented at our center with fetal nuchal abnormalities on first trimester ultrasound went on to have children with RSS. One of the women had also undergone a previous pregnancy termination for fetal anomalies consistent with RSS. The ultrasound findings and details of these 3 cases were reviewed. RESULTS: Both cases of RSS and the third suspected case were found to have nuchal abnormalities on first-trimester scan. All went on to develop malformations consistent with RSS detectable on second-trimester ultrasound. The later 2 cases continued to term and the children had facial characteristics consistent with RSS. CONCLUSION: First-trimester ultrasound assessment of nuchal translucency could be considered as a method for identifying sib recurrences of RSS. In addition, RSS should be on the differential diagnosis when increased nuchal translucency is seen on first-trimester scan.
