Case ReportsCentral nervous system signs in X-linked Charcot-Marie-Tooth disease after hyperventilation.
The X-linked Charcot-Marie-Tooth disease is the second most common form of inherited neuropathy and, unlike most other forms of this disease, may present with atypical manifestations because of central nervous system involvement. Episodic central nervous system symptoms in X-linked Charcot-Marie-Tooth disease may be triggered by illness, dehydration, physical exercise, or exposure to altitude. We describe a child with transient episodes of hemiplegia after simple hyperventilation, a presentation not previously described in pediatric Charcot-Marie-Tooth disease type X.

ReviewCerebral blood flow and autoregulation after pediatric traumatic brain injury.
Traumatic brain injury is a global health concern and is the leading cause of traumatic morbidity and mortality in children. Despite a lower overall mortality than in adult traumatic brain injury, the cost to society from the sequelae of pediatric traumatic brain injury is very high. ⋯ Although altered cerebrovascular hemodynamics early after traumatic brain injury may contribute to disability in children, there is little information regarding changes in cerebral blood flow and cerebral autoregulation after pediatric traumatic brain injury. This review addresses normal pediatric cerebral physiology and cerebrovascular pathophysiology after pediatric traumatic brain injury.
