Barnet A B - - 1978
Computer-averaged auditory evoked potentials were found to be abnormal in infants hospitalized because of severe malnutrition (marasmus). They improved as the infants' somatic growth improved during the course of treatment, but were still deviant at the time of discharge from the hospital and at subsequent outpatient follow-up. Abnormalities in evoked ...

The effects of perceived cuteness of infant photographs on the behaviour of young adults was investigated. Looking, facial muscle activity, and skin conductance were measured during individual presentations of the photographs, whereas only looking was measured during paired presentations. Both measures of looking time were significantly affected by the perceived ...

Posterior fossa subdural hematomas in the newborn infant are rare but potentially treatable. The infants are normal after birth, but within days, hydrocephalus hypotonia, and irregular respirations develop. Seizures and third nerve pareses are unusual. We report a neonate in whom this process was identified by computerized tomographic brain scan. ...

An anencephalic infant, 3 to 6 weeks old, responded to acoustic stimulation with cardiac decelerations typical of the response pattern seen in normal, older infants. Such precocity implies unexpected competence of lower brain structures and suggests that, in the normal infant, feedback from immature higher centers may sometimes interfere with ...

Use of neurologic criteria to pronounce death, although accepted by many, has caused controversy among physicians, lawyers, legislators, philosophers, and theologians. The present work attempts to resolve this by accomplishing four objectives. (1) It summarizes scientific information that establishes the ability to determine the state of brain death with certainty ...
Adams R D - - 1977
Report is given on the first example in which the clinical and electrographic criteria of brain death were obtained at birth. Global destruction of the central nervous system of a type seen only with anoxia and circulatory failure had occurred in utero without appreciable disturbance of maternal health. Neuropathologic reaction ...

Eighty normal human brains varying from 22 weeks' gestation to 1 month postnatal life were graded according to convolutional development and compared with the microscopical development of kidneys and the gestational age as given by the mother. Excellent correlation was obtained between the gross appearance of the brain and the ...
Leech R W - - 1977
Although the human brain stem is considered relatively invulnerable to ischemic anoxia, evaluation of 16 cases of a single acute asphyxial episode either at or following birth indicates that such involvement is a frequent and characteristic aspect of anoxic encephalopathy in the infant. Ischemic cell change, neuronal loss, and nuclear ...

A fatal case of mepivacaine poisoning in a newborn infant is reported. Regional brain tissue concentrations of mepivacaine were determined by a sensitive and specific gas chromatographic-mass spectrometric method. The brain tissue levels in this patient were higher than those previously reported, possibly due to alkalosis occurring several hours prior ...

The recent abandonment of the only active US protocol for harvesting organs from anencephalic "donors" indicates both the practical and the ethical problems inherent in such an effort. Various data suggest that surprisingly few such organs would actually end up benefiting other children. Attempts to revise either the Uniform Anatomical ...

In an infant rhesus monkey brain damage resulted from subcutaneously administered monosodium glutamate. Although a relatively high dose of monosodium glutamate was used, the infant was asymptomatic for a 3-hour observation period during which time hypothalamic neurons were undergoing a process of acute cell death. With the electron microscope it ...
