126 Couldwell, William T.Medical and surgical management of microprolactinomaA recent report by Colao et al. [1] indicates that a significant proportion of patients harboring prolactinomas treated with cabergoline will have persistence of remission of hyperprolactinemia following withdrawal of the drug.

127 Kestle, John R. W.; MacDonald, Joel D.; Couldwell, William T.Efficacy of multiple intraarterial papaverine infusions for improvement in cerebral circulation time in patients with recurrent cerebral vasospasmObject. Cerebral vasospasm that is caused by aneurysmal subarachnoid hemorrhage and that is refractory to maximal medical management can be treated with selective intraarterial papaverine infusions.

130 Kestle, John R. W.; Brockmeyer, Douglas LeeComplications of intracranial pressure monitoring in children with head traumaObject. Intracranial pressure (ICP) monitoring has become routine in the management of patients with traumatic brain injury (TBI).

142 Kestle, John R. W.Assessing the validity of the endoscopic shunt insertion trial: did surgical experience affect the results?Object. Most surgical procedures are associated with a learning curve in which the success rate is lower early in the experience before mistakes have been identified and modifications made to the procedure. Negative results obtained early in a trial's learning curve may be a matter of timing rather ...Endoscopic shunt insertion; Ventriculoperitoneal shunt; Pediatric neurosurgery; Surgical experience2004-01-01
