Key points Although there have been significant improvements in the survival of infants with congenital heart disease (CHD), they remain at high risk for neurodevelopmental impairments. Brain dysmaturation and brain injury are key brain changes contributing to adverse neurodevelopmental outcomes…
Introduction Despite marked improvements in antenatal and perinatal care, perinatal brain injury remains one of the most important medical complications in the newborn resulting in significant handicap later in life. Experimental advances have helped to understand many of the cellular…
Case description ( Fig. 14.1 ) The patient was born at 40 weeks’ gestation and weighed 3150 g at birth. An emergency cesarean section was performed for suspected fetal compromise with bradycardia on the cardiotocogram because of a nuchal cord.…
Gaps in knowledge 1. The severe hypotonia and hyporeflexia in Prader-Willi syndrome (PWS) may lead to unnecessary invasive tests such as electromyography, muscle biopsy, and/or genetic testing for spinal muscular atrophy (SMA). Genetic testing for PWS is not well understood…
