Immunocytochemical study of human brain showed creatine kinase brain isoenzyme (CKBB) present in both neurons and astrocytes. Because creatine kinase brain isoenzyme is an intracellular enzyme that might be released with brain injury, its concentration in the CSF of newborns was measured using a radioimmunoassay. Infants who suffered a documented ...
Baumann R J - - 1985
Neonatal herpes simplex encephalitis (HSE) can represent a difficult diagnostic problem when it occurs without concomitant mucocutaneus lesions and usually requires brain biopsy for diagnosis. Asymptomatic for the initial 2 to 4 weeks of life, the three infants we describe with localized HSE came to medical attention only because they ...
Noetzel M J - - 1985
A case of theophylline neurotoxicity in a three-month-old infant is reported. Prolonged focal seizures with secondary generalization resulted in hemiparesis and developmental retardation, and CT demonstrated cerebral hemiatrophy. Later the infant developed recurrent focal and atonic convulsions, which were refractory to multiple anticonvulsants. Possible etiological factors, especially the pharmacological mechanisms ...
Tamminga P - - 1985
An infant is presented with a Marfanoid phenotype and congenital contractures. In addition to this she showed severe neurological and ocular abnormalities. Cardiac insufficiency due to mitral and tricuspidal valve prolapse caused her death at the age of 6 months. Postmortem examination showed axonal pathology of the anterior horns and ...
Amato M - - 1985
Creatine kinase brain isoenzyme (CK-BB) may be released into the serum after brain injury. Its concentration was measured serially in a group of 80 term infants at risk of perinatal hypoxic damage.

Digital intravenous cerebral angiography was performed in 13 neonates. Injections were made either centrally into the right atrium or peripherally into a distal vein. Seven infants suffered from anoxia, one infant had clinical brain death, another had focal infarcts, and two had intracranial hemorrhage. One infant had an intracranial tumor ...
Thompson J R - - 1984
The x-ray attenuation values of brain studied with computed tomography (CT) are strikingly affected by the ages of the subjects. Premature neonates, for example, may have brain attenuation values 20-30 H below adult values. These lower attenuation values for developing compared with adult brain can be ascribed partly to machine-related ...
Stannard M W - - 1984
Through the acoustic window of the anterior fontanelle, coronal and parasagittal sonograms of the infant and premature neonate are easily obtained. Supplementary axial images are obtained through the lateral skull vault. The normal anatomy of axial, coronal, and sagittal sonograms will be demonstrated by correlating normal infant brain images with ...
Takahashi T - - 1984
When 3,5-dimethyl-3'-isopropyl-L-thyronine (DIMIT) (10 ng/(g X day] was administered to pregnant rats, their infants showed signs of hyperthyroidism with suppressed body weight, tachycardia, and tremor at the day of birth. The brain weight did not change but the wet weight of the cerebral cortex was increased in the infants. Tubulin ...
