BACKGROUND AND PURPOSE The neuroanatomic substrate of cognitive deficits in long-term survivors of prematurity with PVL is poorly understood. The thalamus is critically involved in cognition via extensive interconnections with the cerebral cortex. We hypothesized that the thalamus is atrophic (reduced in volume) in childhood survivors of prematurity with(More)
In the Childhood Brain Tumor Consortium database, the proportions of older children (> or = 11 yr) with pilocytic astrocytomas, fibrillary astrocytomas, and ependymomas significantly increased (P < 0.05) over the 50 years (1930-1979) of the study. The increased proportions of pilocytic astrocytomas occurred whether the tumors were located in the(More)
Opsoclonus-myoclonus ataxia syndrome is a paraneoplastic syndrome of cerebellar damage associated with neuroblastoma. The authors assessed psychiatric symptoms of opsoclonus-myoclonus ataxia syndrome in 17 children, who were 16 months to 12(1/2) years of age. Psychiatric symptoms examined included disruptive behavior, affective dysregulation, irritability,(More)
Nineteen children were acutely dysphoric, inattentive, irritable, and sometimes mute following midline posterior fossa neoplasm resection and arteriovenous malformation hemorrhage. These symptoms represent an acute manifestation of the cerebellar cognitive affective syndrome. The authors aimed to describe the acute psychiatric changes in mood and behavior(More)
The study of delirium has been neglected in pediatric patients, and there are no diagnostic criteria or rating scales adapted for use in this age group. The Delirium Rating Scale is widely used to diagnose and rate the severity of delirium in adults. It was retrospectively administered to 84 children and adolescents diagnosed with delirium to evaluate its(More)
Collins' law (CL) states that the period of risk for recurrence for a tumor is the age of the patient plus 9 months. Originally a clinical observation in Wilms' tumor, CL has been applied to other tumors such as medulloblastoma (MB). Although CL does not apply to all childhood tumors, it seems to be a valid observation for childhood MB, despite several(More)
The Daumas-Duport grading scheme (DDGS) is a commonly used method for determining the grade of a tumor. It scores 4 histologic features and is used as a prognostic tool in adult astroglial tumors. This system of assigning children to prognostically homogeneous groups has not been evaluated. The Childhood Brain Tumor Consortium (CBTC) database includes 327(More)
Rarely reported in pediatric patients, the characteristic symptoms and course of delirium are well known in adults. This retrospective study was undertaken to describe the clinical presentation, symptoms, and outcome of delirium in children and adolescents. Eighty-four patients age 6 months to 18 years were identified with delirium, from 1,027 consecutive(More)
BACKGROUND AND PURPOSE To date, very limited attention has been given to ocular abnormalities or growth parameters detected by fetal MR imaging. Our objective was to retrospectively determine the relationship between different parameters of eye development and estimated gestational age in the human fetus by use of fetal MR imaging. MATERIALS AND METHODS A(More)
Delirium is presumed to be the same syndrome in all ages. Comparing pediatric and adult studies, the authors found many of the same symptoms reported, but often at significantly different rates. Sleep-wake disturbance, fluctuating symptoms, impaired attention, irritability, agitation, affective lability, and confusion were more often noted in children;(More)
