Haemorrhages into the subarachnoid space lead to scarlike changes in the leptomeninges in some patients. If these changes reach a certain severity, circulation of the C.S.F.. is compromised and absorption reduced. This eventually results in ventricular dilatation which, in severe cases, is clinically manifested by dementia, motor ataxia and incontinence. The early stages of the disturbance in C.S.F. circulation were examined scintigraphically in 165 patients with spontaneous traumatic or operative subarachnoid bleeding. In the presence of abnormal findings which suggested the need for C.S.F. shunting, air encephalography was carried out in addition. Special attention was paid to the demonstration of the extent and localisation of occlusions of the basal cisterns and of the cortical subarachnoid spaces. Typical scintigraphic and pneumoencephalographic findings are demonstrated and their diagnostic value compared.

Recently extension of malignant glioma to the spinal cord (meningeal gliomatosis: MG) has been described with increasing frequency as the advancement of the therapy for brain tumor. However, the study for clinicopathological features of MG has not been established and its therapy has still been difficult. We tried to produce experimental models of MG using nude mice and study experimental immunotherapy with human monoclonal antibody (CLN-IgG MoAb). U87-SC1 human glioma cells (5 x 10(5) in 20 microliters) were inoculated transcutaneously into the cisterna magna of BALB/c nu/nu mice using a 27-gage needle. Daily weights, neurological findings and survival time were examined. MRI scan was performed after neurological deterioration and histological examination was also performed after death. CLN-IgG MoAb was used for treatment and 15 nude mice which were inoculated with tumor cells into the cisterna magna (Day 0) were divided into three groups of 5 mice each. Group A was control group which received saline into the cisterna magna, Group B and C received 50 micrograms of CLN-IgG into the cisterna magna on Day 2 or Day 7 following inoculation of tumor cells. Efficacy of experimental immunotherapy was statistically evaluated by the difference of median survival time (MST) among three groups. All of the nude mice lost weight within 4 or 5 days after inoculation of tumor cells and developed paraplegia or tetraplegia with incontinence and died. MRI of the nude mice which showed neurological deteriorations revealed ventricular dilatation, infiltration of tumor cells to the spinal cord and spread of tumor cells into the subarachnoid space.(ABSTRACT TRUNCATED AT 250 WORDS)

The siblings of Sanfilippo syndrome type A (MPS III A) have been reported. The relationship of their parents was the first cousins. Case 1: A 30-year-old Japanese man was hospitalized because of gait disturbance and mental impairment. His early somatic and mental development was normal until 9 years of age when mental deterioration had developed. Speech and gait disturbances and double incontinence occurred at 18 years of age. He could not walk at 21 years of age. Those symptoms were slowly progressive. Case 2: A 32-year-old Japanese man, the elder brother of case 1, had a similar clinical history to that of case 1. Their neurological findings revealed mental impairment, coarse face, positive forced grasp and sucking reflexes, and pyramidal signs. Lumbar X-ray showed platyspondylitis, compression fracture of L 1 and osteoporotic changes. Brain MRI of both cases showed brain atrophy, ventricular dilatation and abnormal high intensity signals near the posterior horn of the lateral ventricles on T2 weighted image. Low perfusion images of fronto-parietal regions were seen in the early phase of SPECT using 123I-IMP. This siblings were diagnosed as Sanfilippo syndrome type A because of heparan sulfaturia and deficiency of heparan sulfate sulfamidase of the lymphocytes. Average life span of Sanfilippo syndrome type A is not so long but the age of our cases is over 30 years of age.

In normal pressure hydrocephalus (NPH), the physiological alterations related to the ventricular dilatation that lead to the Hakim and Adams clinical syndrome (gait apraxia, incontinence and dementia) remain unclear. The correlation between the clinical syndrome and global or regional cerebral blood flow (CBF) is not established. The question whether the CBF reduction is the cause or the consequence of the neural dysfunction remains unsolved. Dementia of NPH may be a combination of fixed and potentially treatable pathologies. Expectations for improvement in the dementia of NPH must be tempered by the knowledge that they may be fixed tissue damage prior treatment. The overall poor clinical outcome after shunting with regard to dementia, when contrasted with responses in gait and continence, suggests differences in aetiology or reversibility of the pathology underlying these symptoms. It is not easy to choose elderly patients (perhaps patient with more impaired psychometric performances) that might respond to a shunt.
