"My child doesn't have a brain injury, he only has a concussion".

Objective: The term "concussion" is frequently used in clinical records to describe a traumatic head injury; however, there are no standard definitions of this term, particularly in how it is used with children. The goals of this study were to examine the clinical correlates of the concussion diagnosis and to identify the factors that lead to the use of this term in a regional pediatric center.

Methods: Medical data were prospectively collected from 434 children with traumatic brain injury who were admitted to a Canadian children's hospital.

Navigating the gray zone: a guideline for surgical decision making in obstetrical brachial plexus injuries.

Object: In the literature, the best recommendations are imprecise as to the timing and selection of infants with obstetrical brachial plexus injury (OBPI) for surgical intervention. There is a gray zone (GZ) in which the decision as to the benefits and risks of surgery versus no surgery is not clear. The authors propose to describe this category, and they have developed a guideline to assist surgical decision-making within this GZ.

Ventricular catheter tack-down screw.

The frequent need for revision of ventriculoperitoneal shunts particularly in the pediatric population is a well-known complication of the procedure. A not infrequent etiology demanding revision is the dislodgement of the catheter, particularly, in our experience, with posterior fossa shunts. Suturing the shunt to the periosteum is a common practice amongst pediatric neurosurgeons.
