Case ReportsHydrocephalus-induced neurogenic stunned myocardium and cardiac arrest in a child: completely reversed with CSF diversion.
Neurogenic stunned myocardium (NSM) is a potentially fatal cause of sudden cardiogenic dysfunction due to an acute neurological event, most commonly aneurysmal subarachnoid hemorrhage in adults. Only two pediatric cases of hydrocephalus-induced NSM have been reported. Here the authors report a third case in a 14-year-old boy who presented with severe headache, decreased level of consciousness, and shock in the context of acute hydrocephalus secondary to fourth ventricular outlet obstruction 3 years after standard-risk medulloblastoma treatment. ⋯ All other causes of heart failure were ruled out, and his impressive response to CSF diversion clarified the diagnosis of NSM secondary to hydrocephalus. He was unable to be weaned from his drain during his time in the hospital, so he underwent an endoscopic third ventriculostomy and has remained well with normal cardiac function at more than 6 months' follow-up. This case highlights the importance of prompt CSF diversion and cardiac support for acute hydrocephalus presenting with heart failure in the pediatric population.

Selection of children with ultra-severe traumatic brain injury for neurosurgical intervention.
A recent retrospective study of severe traumatic brain injury (TBI) in pediatric patients showed similar outcomes in those with a Glasgow Coma Scale (GCS) score of 3 and those with a score of 4 and reported a favorable long-term outcome in 11.9% of patients. Using decision tree analysis, authors of that study provided criteria to identify patients with a potentially favorable outcome. The authors of the present study sought to validate the previously described decision tree and further inform understanding of the outcomes of children with a GCS score 3 or 4 by using data from multiple institutions and machine learning methods to identify important predictors of outcome. ⋯ AUC = area under the curve; ER = Emergency Room; GCS = Glasgow Coma Scale; GOS = Glasgow Outcome Scale; GOS-E = Extended GOS; ICP = intracranial pressure; MVA = motor vehicle accident; NAT = nonaccidental trauma; RH = Riley Hospital; TBI = traumatic brain injury; tSAH = traumatic subarachnoid hemorrhage; UCD = UC Davis.

Multicenter StudyA study of pediatric cerebral arteriovenous malformations: clinical presentation, radiological features, and long-term functional and educational outcomes with predictors of sustained neurological deficits.
Large experiences with the treatment of pediatric arteriovenous malformations (AVMs) remain relatively rare, with limited data on presentation, treatment, and long-term functional outcomes. Because of the expected long lifespan of children, caregivers are especially interested in outcome measures that assess quality of life. The authors' intention was to describe the long-term functional outcomes of pediatric patients who undergo AVM surgery and to identify predictors of sustained neurological deficits. ⋯ Pediatric patients with AVMs treated with microsurgical resection have good functional and radiological outcomes. There is a high rate (38%) of persistent neurological deficits, which were independently predicted by preoperative deficits, AVMs > 3 cm, and lesions located in eloquent cortex. This information can be useful in counseling families on the likelihood of long-term neurological deficits after cerebral AVM surgery.
