Q

Define mild traumatic brain injury, according to the American Congress of Rehabilitation Medicine.

A

physiological disruption of brain function, with at least one of the following criteria:

  • any period of LOC
  • any loss of memory for events immediately before or after the accident
  • any alteration of mental state at the time of accident (e.g.: feeling dazed, confused, disoriented)
  • focal neurological deficits that may or not be transient

but where the severity of the injury does not exceed the following:

  • LOC approximately 30 minutes or less
  • after 30 minutes, an initial GCS 13-15; and
  • posttraumatic amnesia not greater than 24 hours

26
Q

most common MRI finding in children with spina bifida

A

By definition, all children with myelomeningocele have a tethered cord on MRI, but only about 20% of children require an operation to untether the spinal cord during their first decade of life, during their rapid growth spurts. Thus, the MRI scan must be placed in context of a history and examination consistent with mechanical tethering and a resultant neurologic deterioration
