Contrast enhancement of the irradiated spinal cord in children.

Four children are reported in whom marked contrast enhancement of the spinal cord and roots was demonstrated by computed tomography months to years after relatively low dose therapeutic irradiation of paraspinal tumors, the radiation field including the cord. This phenomenon, previously unreported, probably represents subclinical radiation injury. None of the children had any neurologic abnormalities.

Iatrogenic embolization: complication of pediatric cerebral angiography.

Fourteen cases of inadvertent iatrogenic embolization of cerebral vessels occurring in a consecutive series of 3,731 angiographies in infants and children were studies. The incidence of embolization(0.9% of all patients ond 0.4% of all angiographic examinations) was about the same as has been reported in adults, but the clinical consequences were much milder, only one patient having documented transient neurologic symptoms. Also the angiographic appearance of the emboli differed from those described in adults. These differences may in part be due to the technique (general anesthesia with hyperventilation) but also to different reactions towards ischemia and to different types of emboli in children.

Expanding access to emergency contraception in developing countries.

Emergency contraception has been called the best-kept contraceptive secret. Previous research shows that several regimens of postcoital contraception offer safe and effective ways for women to avoid pregnancy. Yet the methods are typically unavailable to women in developing countries. In this article, the authors review the main methods of emergency contraception and describe experience with them to date. The prevalence and urgency of the need for making these methods available to women in developing countries are assessed. The necessary elements for creating such access are described. In several developing countries, conditions for introducing the methods may be more favorable than in industrialized countries. These advantages are reviewed. Finally, the authors describe the challenges anticipated for broadening the availability of postcoital methods in the developing world. They conclude with a brief series of recommendations for policymakers.
