title: CSF polyamines in childhood.
abstract: Specimens of CSF from 76 children without neurologic disease and from 191 children with neurosurgical conditions were assayed for polyamine content. Putrescine and spermidine concentrations decreased with age. In children with intracranial tumors, polyamine concentrations in lumbar CSF were comparable with those in ventricular CSF. Putrescine level was significantly increased in children with medulloblastomas. Spermidine level was increased in children with medulloblastomas, glioblastomas, and astrocytomas. Concentrations of putrescine and spermidine were significantly increased in infants with myelomeningocele and hydrocephalus. Spermidine concentrations were significantly increased in older children with myelomeningocele, encephalocele, and hydrocephalus. Polyamines thus seem to be increased by rapid cell proliferation and by disorders affecting myelination. Since putrescine and spermidine concentrations may be of use in monitoring tumor progression, the effects of childhood growth and of hydrocephalus must be considered for children whose brain tumors are associated with hydrocephalus.
