Background: Complete hydatidiform mole and a co-existing normal fetus (CHMCF) is associated with a high complication rate. A possible association with assisted conception might increase the prevalence of CHMCF.

Objectives: To study the potential association between assisted conception and the risks of CHMCF.

Methods: Case series at a single university hospital from 2008 to 2018 are presented and contrasted with data from a comprehensive literature review (1998–2018). Cases were identified from the institutional database that matched the sonographic criteria for CHMCF. A literature review showed comparable cases.

Results: None of the three pregnancies presented in this article resulted in a viable fetus, all were aborted. One of the three patients needed chemotherapy due to gestational trophoblastic neoplasia (GTN). A literature search identified 248 reported cases in which 22 fetuses (9%) reached term, 88/248 (35%) progressed to GTN, and 25/120 (21%) were conceived following assisted conception. From 2008 until 2018 at our medical facility, there were 3144 twin pregnancies of which 1667 (53%) were conceived using assisted conception. In our cohort, there was no statistical trend for assisted conception as an etiological factor for CHMCF.

Conclusions: No association between assisted conception and the risk for CHMCF was established at our hospital, although approximately one-quarter of all reported CHMCF pregnancies are attributed to assisted conception technology. However, these data are not always reported, making it difficult to draw definitive conclusions.

The recent paper by Giubilini and Minerva suggesting the ethical permissibility of infanticide of normal newborns, calling it “postbirth abortion,” represents a dangerous deterioration of generally accepted ethical norms. Their proposal represents a clear example of the so-called slippery slope and we caution against abandoning the age-old traditions of the medical profession assigning intrinsic value to human life from birth. This article discusses the proposed concept, makes comparisons with earlier similar trends of thought, and highlights the dangers of the proposal.

Background: Prenatal lead exposure (umbilical cord blood lead concentration 10 (μg/dl) may impair cognitive development. Childhood lead poisoning is infrequent in Israel, and there are no data on lead exposure in immigrants to Israel from the former Soviet Union.

Objectives: To evaluate prenatal blood lead concentrations in Israeli newborns whose mothers were born in Israel and in those whose mothers recently immigrated from Russia, and to compare data of prenatal lead exposure in Israel with those reported from other countries.

Methods: We compared the UCBLC of 35 newborns of new immigrants from Russia with a group of 35 newborns whose mothers were born in Israel. Venous BLC was also measured in 50 mothers. Data are compared with similar reports on prenatal lead exposure internationally.

Results: The UCBLC in all 70 newborns (mean±SD) was 3.53±1.6 μg/dl, and mothers' BLC (mean±SD) was 3.90±1.39 μg/dl. UCBLC and BLC in the 50 mother-newborn pairs correlated (γ=0.36, P<0.01). All newborns except one had UCBLC<8.0 μg/dl. There was no significant difference between UCBLC in the two groups.

Conclusions: Prenatal lead exposure among the study subjects in both groups was low. In this sample the newborns of mothers born in Israel and those whose mothers recently immigrated from Russia were not found to be at risk for lead poisoning. Prenatal lead exposure in this sample was low compared to that reported from various parts of the world.
