Decisions regarding pregnancy termination among Bedouin couples referred to third level ultrasound clinic.
OBJECTIVE: To identify predictors of parental decision whether to terminate a pregnancy after a diagnosis of a major congenital malformation in a traditional society. STUDY DESIGN: The Bedouin Arabs in southern Israel are a traditional society, with a high incidence of congenital disorders. Data were abstracted from medical records of 295 families who sought counseling in the third level ultrasound clinic between 1990 and 1996. Statistical analysis included univariate and multiple logistic regression. RESULTS: The diagnosis of a major malformation was confirmed in 64% of the cases. Pregnancy termination was a realistic option for 125 women (66.5%) as the rest were too advanced in their pregnancy. Such a delay was less common in cases of multiple malformations than in a single malformation (19.2% versus 39.0% respectively, P < 0.01). Forty-nine of the 125 women (39.2%) chose to terminate their pregnancy. The only significant predictors of termination decision were earlier gestational week at diagnosis and previous uncompleted pregnancies. CONCLUSIONS: These findings indicate the importance of promoting early genetic counseling and early prenatal diagnosis, for any population where abortions are not readily acceptable.

The relationship between congenital cardiovascular malformations and spontaneous abortion in preceding pregnancy.
Previous studies have shown an increased frequency of spontaneous abortions in the pregnancy preceding a fetus or a newborn with neural tube defect (NTD) compared with a normal newborn. One explanation of this observation is the trophoblastic cell rest hypothesis put forward by Knox and Clarke, suggesting a teratogenic interaction between the developing embryo and pathological remnants of a previous pregnancy. The other explanation is that the previously lost fetus was also affected with neural tube defect. The aim of this study was to verify whether this observation is also valid for congenital cardiovascular malformations (CCVM). Demographic and obstetric data of 99 mothers (58 Jewish and 41 Bedouin) of newborns who died in the neonatal period from isolated CCVM were compared with those of 103 mothers (48 Jewish and 55 Bedouin) of newborns who died of congenital defects other than NTD and CCVM. Spontaneous abortions in the preceding pregnancy were found in 32% of the cases with CCVM compared with 14% of cases with other defects (ODs) (P=0.0012; odds ratio=3.1, 95% confidence interval 1.5-6.4). This significant difference was independent of maternal age and number of pregnancies or deliveries. No difference was found between Jews and Bedouins. As there is no indication in the literature that fetuses with isolated CCVM tend to be spontaneously aborted, our findings are more supportive of the trophoblastic cell rest theory.

Uterine artery Doppler velocimetry in patients with idiopathic hydramnios.
OBJECTIVE: To evaluate the role of overdistended uterus on the uterine artery (UA) blood flow velocimetry by comparing UA Doppler in patients with idiopathic hydramnios to patients with normal amniotic fluid (AF) volume. METHODS: Pulsatility index (PI) of both UAs was determined prospectively between 26 and 41 weeks of gestation in 72 consecutive pregnant women with singleton pregnancies and idiopathic hydramnios and in 72 pregnant women with normal AF volume. Hydramnios was defined as an AF index (AFI) above 24 cm. A normal amount of AF was defined as an AFI of 6-24 cm. Patients with known fetal structural or chromosomal anomalies and those with diabetes mellitus were excluded. RESULTS: No significant differences were observed between the groups with regard to maternal age, gravidity, and gestational age at examination. Gestational age at delivery and accordingly birth weight were significantly lower in patients with hydramnios compared to those with a normal AFI (34.9 +/- 2.1 vs. 39.1 +/- 1.2, p < 0.001; 2,508 +/- 399 vs. 2,995 +/- 420, p < 0.001, respectively). No significant differences were noted between right UA PI (0.73 +/- 0.3 in the hydramnios group vs. 0.71 +/- 0.2 in the control group; p = 0.091) and left UA PI (0.91 +/- 0.3 in the hydramnios group vs. 0.84 +/- 0.3 in the control group; p = 0.131) of both groups. CONCLUSION: UA velocimetry in patients with idiopathic hydramnios was not significantly different from those with a normal AF volume.
