Computerized axial tomography in chronic seizure disorders of childhood.

Ninety-eight children with chronic seizure disorders were studied by computerized axial tomography (CAT). Structural abnormalities were identified in 30% of these children. The greatest incidence of abnormalities was in children with focal motor seizures (43%) and in those whose EEG demonstrated focal slowing together with focal spikes (38%). The most common abnormality was either focal or generalized atrophy (13%). Only about 2% of the abnormalities discovered by CAT were potentially of therapeutic significance. However, the demonstration of a static process, or the finding of a normal CAT, may be quite helpful to the family and physician in certain children with chronic seizure disorders.

Hemophilus meningitis: comparison of H. influenzae and H. parainfluenzae.

Eleven cases of Hemophilus meningitis seen in the last year are reported. Three were H. parainfluenzae and eight were H. influenzae. The number of patients is small but probably indicates that there is little difference in the clinical or laboratory data in meningitis caused by these two organisms. The children with H. parainfluenzae tended to be less anemic and had more normal admission spinal fluid sugars and proteins, but this was probably because these patients were older and had shorter prodromes. As more cases of H. parainfluenzae meningitis are noted, it seems likely that there will not be any difference in the clinical or laboratory data. Two of the three cases of H. parainfluenzae meningitis had the complication of ataxia secondary to severe bilateral vestibular deficits. Finally, it should be noted that these two organisms will not be distinguished by routine bacteriological studies, and that differentiation must be carried out by an experimental laboratory.

Chronic effects of osmotic opening of the blood-brain barrier in the monkey.

In the monkey, the blood-brain barrier and the blood-aqueous and blood-vitreous barriers of the eye can be opened by internal carotid perfusion of solutions of 2 molar urea in a way compatible with survival and, in some few cases, without detectable neurological deficits. Urea presumably acts by osmotically shrinking the endothelial cells of the cerebrovascular vessels and opening their tight junctions. The high incidence of brain necrosis with neurological sequelae after perfusion of urea by the present technique precludes the use of osmotic opening of the blood-brain barrier for pharmacotherapy at this time.
