Neonatal lead poisoning from maternal pica behavior during pregnancy.
Lead toxicity has gained increasing attention in the public media because of its ubiquitous distribution in the environment and the potentially serious medical complications that it can induce, particularly in children. We present a case of an asymptomatic Hispanic woman who exhibited a unique form of pica during her pregnancy. By serendipity, she agreed to enroll into a lead screening study at our medical center when she presented to deliver her child. Her blood lead level was 119.4 microg/dL at delivery, and simultaneous measurement of the neonate's cord blood lead level was 113.6 microg/dL. The infant underwent an exchange transfusion, and the mother was treated with oral 2,3-dimercaptosuccinic acid. Both demonstrated dramatic biochemical improvement.
