TL;DR: The data suggest that a single fetal urine determination may be insufficient to declare irreversible damage and that decompression by either needle aspiration or intrauterine shunting is warranted in carefully selected cases and can save fetuses that are otherwise very likely doomed.

TL;DR: The presence of viral deoxyribonucleic acid sequences in placental tissue does not correlate with fetal disease and the use of polymerase chain reaction to attempt molecular diagnosis of fetoplacental varicella zoster virus infection in two patients was unsuccessful.

TL;DR: The authors' chorionic villus sampling (CVS) procedure was extended to the second and third trimesters and the results obtained with late CVS and PUBS were obtained faster and may be technically easier to perform.
Abstract: Late pregnancy fetal karyotyping is not employed often because a clinical decision about labor and delivery may be required before the results would be available. However, percutaneous umbilical blood sampling (PUBS) has been used recently to obtain fast karyotypes. We have extended our chorionic villus sampling (CVS) procedure to the second and third trimesters and compared the results obtained with late CVS and PUBS. CVS karyotypes were obtained faster and may be technically easier to perform.
