Intracranial hemorrhage is a complication of extracorporeal membrane oxygenation for the treatment of neonatal respiratory failure. A retrospective review of 35 neonates treated with extracorporeal membrane oxygenation was performed; ten had intracranial hemorrhage. Infants with intracranial hemorrhage had lower birth weights and were gestationally younger than infants with intracranial hemorrhage. ⋯ One child is normal, the other died at 18 months of age. Based on the results of this study, the risk of intracranial hemorrhage appears low in neonates of greater than 34 weeks' gestational age who undergo extracorporeal membrane oxygenation treatment for severe respiratory failure. The use of extracorporeal membrane oxygenation, as it is presently performed, is contraindicated in neonates of less than 35 weeks' gestational age because of the risk of intracranial hemorrhage.

Population-based data on varicella complications are presented using information both from national sample surveys of hospitalizations and physician office visits and from reviews of medical records for all cases occurring within one community (Olmsted County, Minnesota) during a specified period. Acute cerebellar ataxia is the most common neurologic complication of varicella and occurs about once in 4,000 varicella cases among children younger than 15 years of age. Among adults, varicella pneumonia is the most common complication and results in hospitalization about once in every 400 varicella cases. Overall, varicella accounts for approximately 4,000 hospitalizations and 364,000 physician office visits annually in the United States and represents an important continuing source of childhood and adult morbidity.
