Monochorionic dizygotic twins in a spontaneous pregnancy: a rare case report.

Traditionally, monochorionicity in multiple pregnancies is associated with monozygocity. We present a case of a spontaneous, monochorionic dizygotic, sex-discordant twin pregnancy. The diagnosis of monochorionicity was initially done during first-trimester ultrasound evaluation and then confirmed by postnatal placental pathology.

Values of amniotic fluid index in cases of preterm premature rupture of membranes.

Aims: To measure the amniotic fluid index (AFI) in cases of preterm premature rupture of membranes (PPROM).

Methods: A retrospective study of pregnancies complicated with PPROM was performed. Data collected included maternal age, parity, gestational age at PPROM and at birth, and AFI on admission.

The impact of maternal age, body mass index and maternal weight gain on the glucose challenge test in pregnancy.

Objective: The aim of this study was to determine whether maternal age, prepregnancy and mid-trimester body mass index (BMI), or excessive mid-pregnancy weight gain predict abnormal glucose challenge test (GCT) results.

Methods: A retrospective chart review of 75 consecutive singleton pregnancies was performed. Patients were screened at 24-28 weeks of gestation with a 50-g oral GCT.

Combined analysis with amniotic fluid index and estimated fetal weight for prediction of severe macrosomia at birth.

Objective: To evaluate combined analysis with amniotic fluid index (AFI) and estimated fetal weight (EFW) for prediction of severe macrosomia at birth.

Study Design: In this retrospective case-control study, 50 term severe macrosomic newborns (birthweight [BW] > or = 97th percentile) were included in the study group and 100 appropriate for gestational age newborns served as controls. All pregnancies underwent a third-trimester sonographic evaluation in which AFI and EFW were measured.

Pregnancy in peritoneal dialysis: a case report and review of adequacy and outcomes.

A case of pregnancy in a 27-year-old woman on peritoneal dialysis is presented. The case report is a detailed description of her course including changes in her peritoneal dialysis regimen and the use of continuous cycling to maximize dialysis adequacy while addressing the patient's recurrent abdominal pain and fullness. Also described is the management of complications including hypertension, gestational diabetes, and premature rupture of membranes.

Fine-needle aspiration in the evaluation of nucleated red blood cells in the human placenta.

Objective: The purpose of this study was to evaluate the correlation between placental and umbilical cord nucleated red blood cell counts.

Study Design: Eighty placentas and their matched umbilical cord blood samples were collected prospectively immediately after delivery. In vitro fine-needle aspiration biopsy specimens were used to obtain placental tissue samples.

The association of fetal heart rate patterns with nucleated red blood cell counts at birth.

Objective: The purpose of this study was to evaluate the relationship between fetal heart rate patterns and fetal nucleated red blood cell counts.

Study Design: Data were collected prospectively from March through September 2000. Umbilical cord blood was used for nucleated red blood cell analysis.
