Prenatal exposure to polychlorinated biphenyls (PCBs) impairs cognitive development in infants and children, according to numerous studies of these ubiquitous environmental pollutants. Studies of PCB damage have considered many different end points, but the results of these different studies have never been coordinated to pinpoint the neuropsychologic functions most likely to be damaged by pren...

Conclusions to the Supplement, "Extra-Renal Complications of Cystinosis".

One of the founders of the field of inborn errors of metabolism, J. Edwin Seegmiller, once said, “Cystinosis is a durable, but perhaps not doable, problem.” Since he said that more than 50 years ago, great progress has been made in understanding this complex multiorgan, systemic disease.
