Comparative StudyBlood-stained cerebrospinal fluid: traumatic puncture or haemorrhage?
Computed tomography fails to ascertain, or exclude, the presence of intracranial haemorrhage in a considerable number of cases, especially in subarachnoid haemorrhage and haemorrhagic infarcts. A number of other methods, including cerebrospinal fluid spectrophotometry and cytology have, therefore, been tested to define their diagnostic efficacy in 25 cases of confirmed intracranial haemorrhage and in 25 instances of blood-stained cerebrospinal fluid due to traumatic puncture. The combination of spectrophotometry and cytology proved to have a high diagnostic reliability. On the basis of these results a routine scheme of investigation is proposed.

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.

The treatment of raised intracranial pressure following aneurysm surgery.
The effect of intravenous mannitol infusion and withdrawal of cerebrospinal fluid on the intracranial pressure and clinical state was studied in 26 patients with raised intracranial pressure after direct surgery for ruptured aneurysm. Each method decreased the mean intracranial pressure by about 60% of the pre-treatment level. The maximal decrease following mannitol occurred after 60-90 minutes and generally lasted between three and four hours. ⋯ Withdrawal of cerebrospinal fluid lowered the intracranial pressure immediately and the effect persisted for approximately 60 minutes. This could be repeated as often as necessary and was without systemic disturbance, although a patent intraventricular catheter was necessary. The two methods could be used simultaneously.

Clinical and prognostic correlates of EEG in open-heart surgery patients.
Sixty-five patients undergoing cardiac valve replacement were followed for one year by electroencephalography (EEG). Occurrence of delta or sharp wave disturbances of low frequency of dominant activity before operation was found to have prognostic significance. The degree of EEG change after operation correlated with clinical signs of cerebral involvement, and predicted the later course.

Case ReportsHaemorrhage associated with meningioma: a case report and review of the literature.
A case of haemorrhage into a parasagittal meningioma treated by surgical resection is presented. A review of the literature found 43 additional cases of meningioma associated with haemorrhage. By correlating these cases with those from another large series of meningiomas classified by histological type and location, an estimation of the "relative bleeding tendency" of certain classes of meningiomas was made. Haemorrhage associated with meningioma is a serious complication and proper treatment consists of evacuation of the haematoma with resection of tumour.
