A 16-year-old boy was stricken with a progressive neurologic disorder characterized primarily by dementia progressing to severe neurologic debility in 12 months and death 28 months following the first symptoms. Pathologic examination showed a spongiform encephalopathy, consistent witha clinical diagnosis of Creutzfeldt-Jakob disease (CJD). ⋯ These are discussed within the frame of reference of CJD and the spongiform encephalopathies of infancy and childhood. Animal inoculation studies employing post-mortem embalmed brain as inoculum are currently in progress to determine the transmissibility of this patient's disease.

Panencephalopathic type of Creutzfeldt-Jakob disease: primary involvement of the cerebral white matter.
Eight necropsy cases of a "panencephalopathic" type of Creutzfeldt-Jakob disease (CJD) in the Japanese are reported. The reasons why this type should be discussed separately from other types of CJD are that there is primary involvement of the cerebral white matter as well as the cerebral cortex, and that the white matter lesion of one Japanese human brain with CJD similar to the present group has been successfully transmitted to experimental animals.

Experimental obstructive hydrocephalus in the rat: a scanning electron microscopic study.
Hydrocephalus was induced in 12-day old rats by the cisternal infusion of a concentrated kaolin suspension. The animals were killed at day 20 and the ependymal lining of all the ventricles prepared for scanning electron microscopy. The dilation of the ventricles was moderate to gross in all cases. ⋯ Four had tears covered with small round cells, believed to be responsible for the repair of the ependyma. The third ventricle, cerebral aqueduct and fourth ventricle enlarged by incorporating folds of ependyma, present in control animals, into the ventricular walls. The circumventricular organs present in the third and fourth ventricles were not damaged by the dilation of the ventricles, even in severe hydrocephalus.
