Growth of the fetal kidney. Ultrasonographic measurement of the ratio of average kidney diameter to biparietal diameter.
Kidney size was studied ultrasonographically in 101 normal fetuses. A ratio of average kidney diameter to biparietal diameter was established and found to be constant across gestation. Three fetuses with known urinary tract pathology were then studied and were found to have ratios significantly different from normal ones.

Devastating sequelae of alloimmune thrombocytopenia: an entity that deserves more attention.
UNLABELLED: In alloimmune thrombocytopenia, maternal sensitization to a fetal platelet alloantigen results in fetal thrombocytopenia. Even in primipara, 20% of offspring can suffer intracranial hemorrhage, half of which occur in utero. Ninety percent of subsequent pregnancies will be equally or more severely affected. We describe two patients whose previous pregnancies were complicated by neonatal alloimmune thrombocytopenia (NAIT). As expected, NAIT recurred, with devastating sequelae in both cases. One case presented with hydrops fetalis, a previously unreported association; the other fetus developed extensive intracranial hemorrhages in utero. Because both previous obstetrical histories had gone unrecognized, no preventative strategies had been undertaken. CONCLUSION: Better recognition of this disease through a positive obstetrical history is needed in order to properly counsel patients and institute appropriate prenatal treatment regimens.

The association of anti-P and early abortion.
The current report details the serologic findings in a case reported previously of a P1k woman, para 0 gravida 13, who was treated during her fourteenth pregnancy with plasmapheresis to reduce the anti-P titer. These studies suggest that anti-P can induce early abortion in Pk women and that the abortions are immunologically mediated. Further, this case supports the disputed proposal that the anti-P component of anti-PP1Pk is responsible for pregnancy loss in p women.
