Nonsurgical management of pediatric tracheal perforation.

Tracheal perforation is a rare complication of intubation. In the pediatric population, the rates of morbidity and mortality are high if diagnosis and management are delayed. Recommendations for treatment in these patients are based on the several reports of this injury in the adult and neonate populations.

Biochemical, cellular, and molecular mechanisms in the evolution of secondary damage after severe traumatic brain injury in infants and children: Lessons learned from the bedside.

OBJECTIVE: To present a state-of-the-art review of mechanisms of secondary injury in the evolution of damage after severe traumatic brain injury in infants and children. DATA SOURCES: We reviewed 152 peer-reviewed publications, 15 abstracts and proceedings, and other material relevant to the study of biochemical, cellular, and molecular mechanisms of damage in traumatic brain injury. Clinical studies of severe traumatic brain injury in infants and children were the focus, but reports in experimental models in immature animals were also considered.

Alterations in inducible 72-kDa heat shock protein and the chaperone cofactor BAG-1 in human brain after head injury.

The stress response in injured brain is well characterized after experimental ischemic and traumatic brain injury (TBI); however, the induction and regulation of the stress response in humans after TBI remains largely undefined. Accordingly, we examined injured brain tissue from adult patients (n = 8) that underwent emergent surgical decompression after TBI, for alterations in the inducible 72-kDa heat shock protein (Hsp70), the constitutive 73-kDa heat shock protein (Hsc70), and isoforms of the chaperone cofactor BAG-1. Control samples (n = 6) were obtained postmortem from patients dying of causes unrelated to CNS trauma.
