A total of 92 patients with hydrocephalus were studied. The incidence of seizures was significantly greater in the "shunted" group (18.2% in the "non-shunted" and 65.4% in the "shunted" group). All of the shunted patients who had seizures developed them after the placement of the shunt. Left sided focal motor seizures were the commonest focal seizures in the patients with right sided shunts. There was a higher incidence of abnormal EEG tracings in the "shunt" group (47% of the "non-shunt" patients and 95% of the "shunt" group). All types of focal EEG abnormalities, but particularly the slow wave foci, were seen more frequently over the hemisphere which had the shunt, and in more than half these localized to the neighborhood of the shunt itself. It is suggested that the shunt, which may act as a foreign body, may be responsible, at least in part, for these findings.

Among 83 head-trauma cases examined by CT scan in a later year, 41 were included in a seizure group of those who clinically showed late epilepsy and who obviously showed epileptic discharge such as spike or spike and wave in EEG after trauma, and 42 were included in a nonseizure group of those who had some sequelae such as abnormal findings in EEG or neurologic defects: the CT findings of these 83 cases were collected and compared with clinical findings, EEG, and other data. The CT findings of these cases were divided into five groups: (A) a normal group; (B) a group showing partial or unilateral ventricular dilatation; (C) a group showing porencephaly in the cerebral parenchyma; (D) a group suspected of cortical atrophy; (E) a group of other cases. Group D contained 44.3% of the cases, and was the largest group; the frequency of seizure was highest in Group C. The CT classification reveals the contradiction of the conventional definition of posttraumatic epilepsy and also poses some problems concerning the disease. CT scan is mostly applied to head trauma in the acute stage, and as for trauma in the chronic stage there are a few reports on chronic subdural hematoma and post-traumatic hydrocephalus. We noticed posttraumatic epilepsy among the sequelae of trauma, and then analyzed CT findings of the epilepsy: the results are reported here.

The increasing number of ampicillin-resistant Haemophilus influenzae recoveries have required a change in the treatment of meningitis due to this organism. Chloramphenicol has been recommended and is an effective though toxic substitute. Streptomycin combined with sulfisoxazole has been as effective as ampicillin in treating H influenzae meningitis. The results of treating 61 children with ampicillin were compared with results of those given streptomycin intramuscularly, in three intrathecal doses with sulfisoxazole intravenously, and by mouth to 50 children. Permanent neurological sequelae, including deafness, mental retardation, and persisting seizures, developed in the six given ampicillin; communic-ting hydrocephalus occurred in one who had been treated with streptomycin and sulfisoxazole. There was no phlebitis, buttocks abscess, or drug eruptions, and treatment was better tolerated in the streptomycin and sulfisoxazole group. This combination is suggested as an effective alternative to ampicillin.

In a survey of 29 hydrocephalic children treated by ventriculoatrial shunt (Holter valve) with a follow-up of 4 years, EEG records before the operation and at least once a year thereafter, the authors can support the view that an epileptogenic focus has developed around the place of insertion of the ventricular catheter in 19 cases, leading to epileptic seizures in 17 up to now. Thus the incidence of convulsions in this particular group of patients is 0.59 (17/29), the limits of confidence 95% being 0.39-0.76. The irritative abnormalities occur usually during the second year after the operation and the delay for the onset of clinical seizures is variable. The age at operation seems to influence the occurrence of the epileptogenic scar. The type of hydrocephalus and especially the presence of an associated cerebral focal lesion can be of importance in the development of clinical seizures.

The paper contains a clinico-morphological description of a case with late sequelae of treated tubercular meningitis. The patient at 7 years of age had tuberculous meningitis which was treated by suboccipital and endolumbar administration of streptomycin. Following 12 years, epileptical seizures ensued with an eventual gradual weakness in the extremities leading to profound spastic tetraparesis. During the last years of life contractures and stem symptoms developed. The morphological picture was characterized by posttuberculous fibrous leptomeningitis with an extensive internal hydrocephalus, universal sclerosis of the cerebral and spinal vessels, disseminated demyelinization in the spinal cord and brain, a distinct improverishment of the grey matter by ganglionic cells. The result of liquorohemodynamical disorders was a syringolike cavity in the spinal cord. Under the ependima of the laral ventricle calcified cholesteatomas were found, which are considered as complications of suboccipital punctures in administering streptomycin.

Four term infants were found by computerized cerebral tomography (CT) to have intraventricular hemorrhage. All were male infants who had experienced substantial intrapartum complications. One infant had subtle clinical signs at 2 days of age; the others had major neurologic findings including seizures and ophthalmoplegia that occurred at 1, 4, and 6 weeks of age, respectively. Three infants in whom the hemorrhages were indistinguishable by CT from those described in preterm infants now have arrested hydrocephalus and normal development. The fourth infant was found to have a large glioblastoma at the site of origin of his initial hemorrhage. These cases emphasize the need to consider this diagnosis in neonates born at term who have abnormal neurologic signs.

Post-shunt subdural hematoma was found in two patients with hydrocephalus due to subarachnoid hemorrhage. The first case was a 46-year-old man with two episodes of subarachnoid hemorrhage from anterior communicating aneurysm. Two weeks after neck-clipping for the aneurysm, a ventriculo-peritoneal shunt with Pudenz's system was performed since hydrocephalus with moderately increased pressure had been found. He did well for one month, then soon after mild head injury, disorientation and right hemiparesis developed. Cerebral angiogram revealed avascular space in the left parietotemporal region. After the ligation of the shunt tube, subdural hematoma was removed. The symptoms improved in two weeks. The second case was a 62-year-old man with an aneurysm at the trifurcation of the right middle cerebral artery. One month after successful clipping of the aneurysm, he received a ventriculoperitoneal shunt with Pudenz's system for normal pressur hydrocephalus. One and a half years after the operations he hit his head against the ground during his convulsive seizure. Since then, disorientation, urinary incontinence and gait disturbance appeared. After cerebral angiogram, the subdural hematoma was removed and the shunt tube was ligated. He became free of these symptoms in two weeks. The cerebrospinal fluid shunt is recommended for hydrocephalus induced by subarachnoid hemorrhage, but careful follow-up is necessary since these patients might develop post-shunt subdural hematoma, especially after head trauma as shown in our cases.

Sequential computerized tomography (CT) was performed on a patient with seizures and an organic mental syndrome. Cerebral sarcoidosis was subsequently diagnosed on the basis of noncaseating granulomas in three organ systems. Cranial nerve palsies, hypothalamic dysfunction, and widespread disease were absent. An unusual neuroradiologic sequence of events indicated focal and asymmetric hydrocephalus, mass effect, ependymitis, diffuse breakdown of the blood-brain barrier, and periventricular white matter destruction. These findings have not been previously described together in a patient with sarcoid. With the advent of noninvasive CT, it is possible to perform serial investigations of encephalopathies of obscure origin. Findings similar to those in the present case should prompt a thorough search for subclinical systemic involvement by sarcoid.

The present paper reports on two twin brothers who presented clinically at birth a syndrome characterized by progressive development of muscular hypertonia, opisthotonus, micrencephaly, amaurosis and short, localized clonic seizures. Both children died soon after one year of age. The anatomic examination performed in one case revealed a spongy degeneration of the brain of van Bogaert-Bertrand type. Associated to the cerebral degenerative syndrome was a severe malformative syndrome characterized by micrencephaly, internal hydrocephalus and pontocerebellar atrophy. The ultrastructure of the cerebellar cortex showed degenerative phenomena in the Purkinje and glial cells, demonstrating the evolutive character of the ponto-cerebellar lesions. The degenerative process consisted of the accumulation of lamellar bodies within the mitochondria and free in the cellular cytoplasm with tendency to form inclusions of the multilamellar or finger-print type. Association of the degenerative with the malformative process is not considered to be accidental but based upon the same fundamental pathologic process: glial dystrophy. It may be assumed that the pathologic defect, which as a rule produces syndromes that appear after birth (spongy degeneration of the brain, ponto-cerebellar atrophy), may in some instances act at an early date in intrauterine life, the glial dystrophy that appears so early producing both the degenerative and the malformative process.

Seven children with rapid enlargement of the head and other clinical features resembling hydrocephalus are described. All children remained with relatively large heads, developed slowly and all but one had various degrees of mental and motor handicaps. The EEG was disturbed in all cases; two children developed seizures. Increased intracranial pressure was present. In all patients the subarachnoid space was markedly widened while the ventricular system was normal or minimally dilated. The characteristics of this syndrome, the features distinguishing it from similar conditions as well as its possible mechanism are discussed.
