- Asphyxia in neonates is characterized by different degrees of hypoxia-ischemia, with the outcome depending on the severity of the underlying brain cell damage. Neurotrophic factors rescue neurons from cell death after injury and promote neuronal survival during development. The authors have used enzyme-linked immunosorbent assay to study levels of nerve growth factor in the cerebrospinal fluid of children with asphyxia at birth (n = 10) and of controls (n = 23), Compared with reference groups the children who had had severe asphyxia had lower or negligible levels of cerebrospinal fluid nerve growth factor in the neonatal period or later. The level of cerebrospinal fluid nerve growth factor measured in the neonatal period was 3.76 +/- 4.13 pg/mL in children with asphyxia (n = 8), which is significantly lower than in children without asphyxia or infection (n = 10) 9.42 +/- 4.09 pg/mL or in those without asphyxia but with infection (n = 13) 17.63 +/- 11.48 pg/mL (P = 0.0186 and P = 0.0013, respectively). However, in some children with asphyxia the cerebrospinal fluid nerve growth factor levels were virtually normal, and most importantly these children subsequently had normal neurologic development. These results suggest that cerebrospinal fluid nerve growth factor might be used as a biochemical marker for early estimates of hypoxic-ischemic brain damage in asphyxiated neonates, (C) 1999 by Elsevier Science Inc.

- Nerve growth factor (NGF) in cerebrospinal fluid was measured by ELISA in ten children with postinfectious diseases and in five children with diseases suggested to be of autoimmune etiology, Three groups of patients were studied: (1) those with moderately elevated concentrations (50.67 +/- 17.02 pg/mL, mean and SEM), (2) those with high concentrations (mean 424.25 +/- 125.41 pg/mL, mean and SEM), and (3) those with enormously high concentrations (mean 2,745 +/- 1,819.46 pg/mL, mean and SEM). We suggest that CSF-NGF could be used as an immunologic marker of an ongoing CNS process, Uncontrolled signaling of NGF receptors may lead to long-term inflammatory and autoimmune responses, which in turn can lead to disease.

Neuropsychologic and Motor Function in Small-for-Gestation Preschoolers

- The aim of this study was to evaluate neuropsychologic and motor performance in term small-for-gestation preschool children. A patient-based sample of 311 5-year-old children with birth weights less than the fifteenth percentile for gestation was compared with a random sample of 321 appropriate-for-gestation control subjects. The main assessment tools were subscales from the Wechsler Preschool and Primary Scale of Intelligence Revised, subscales from the Illinois Test of Psycholinguistic Abilities, tests of manual dexterity and figure copying, and the Peabody Developmental Motor Scales. The small-for-gestation children had mean scores on tests of visuospatial and visuomotor abilities that were one fourth standard deviation lower than appropriate-for-gestation control subjects and slightly lower scores on manual dexterity. The small-for-gestation children were comparable to appropriate-for-gestation children regarding motor performance. We therefore conclude that the neuropsychologic and neuromotor performance in preschool years of term small-for-gestation children is reassuring.

- Background: Acute subdural hematoma (ASDH) and chronic subdural hematoma (CSDH) in infants have been regarded as highly specific for abuse. Other causes of CSDH have not been investigated in a large population.Purpose: The purpose of this study was to investigate to what extent external hydrocephalus is present in infants with ASDH and CSDH undergoing evaluation for abuse.Material and methods: Eighty-five infants suspected of being abused, with ASDH (n = 16) or CSDH (n = 69), were reviewed regarding age, risk factor profiles, craniocortical width (CCW), sinocortical width (SCW), frontal interhemispheric width (IHW), subarachnoid space width (SSW), and head circumference (HC). In infants with unilateral subdural hematoma (SDH), correlations between contralateral SSW and ipsilateral CCW and SDH width were investigated.Results: Infants with CSDH had significantly lower mortality, were more often premature and male, and had significantly higher CCW, SCW, IHW, and SSW than infants with ASDH (P < 0.05). Ipsilateral CCW (R = 0.92, P < 0.001) and SDH width (R = 0.81, P < 0.01) correlated with contralateral SSW. Increased HC was more prevalent in infants with CSDH (71%) than in infants with ASDH (14%) (P < 0.01). Forty-two infants, all with CSDH, had at least one of CCW, SCW, or IHW ≥95th percentile. Twenty infants, all with CSDH, had CCW, SCW, and IHW >5 mm, in addition to increased HC.Conclusion: A substantial proportion of infants with CSDH who had been suspected of being abused had findings suggesting external hydrocephalus.
