NT discordance is more predictive for adverse fetal outcome in MCDA twins than CRL discordance. Neither NT nor CRL discordance are likely to modify the intensive monitoring required for these very high-risk pregnancies.

In death resulting from gunshot wounds it is the routine policy of the Southwestern Institute of Forensic Sciences to examine the hands for evidence of powder and primer residues. In the past three months while performing such examinations the authors encountered three cases in which there was an orange-brown discoloration of the skin of the palm of one hand. Several months ago, one of the authors (V. J. M. D.) had been contacted by another medical examiner who had noticed this phenomenon and did not know its cause. He indicated that his cases were suicides and that the weapon had been a long arm. The authors at that time had no explanation.
