For comparison with the findings in disease, it is necessary to determine the characteristics of the cerebro-spinal fluid in healthy infants and children. Comparatively little work has been done on this subject. In the latest work on the cerebro-spinal fliuid. The Human Cerebro-spinal Fluid, published by the Association for Research in Nervous and Mental Diseases, New York, McLean and Mcintoshl...
I . By means of a cranial transillumination method used in conjunction with lumbar and bregmatic punctures, an increase in the space which contains the cerebro-spinal fluid in the cranial region is suggested in children with severe marasmic malnutrition. 2. The results appear to indicate that this is due to a diminished brain size, creating a space in the interior of the cranium which secondari...
GENERAL ANAESTHESIA fOr pneumoencephalography presents the anaesthetist with a technical problem that has not been solved satisfactorily. The anaesthetic administered should be tailored to meet the demands of patient safety, comfort, possibly increased intracranial pressure and unusual positioning that is necessary during the study. It should also provide a quiet patient for the radiologist to ...
In order to measure cerebral atrophy due to neurodegenerative diseases, the major confounding factor of normal age-related atrophy must be taken into account. Furthermore, in order to compare cerebral volume measurements across multiple subjects, normalisation for differences in head size is also required. We describe an investigation of these normalisations based on measurements of cerebro-spi...
Central Nervous System malignancies often require stereotactic biopsy or biopsy for differential diagnosis, and for tumor staging and grading. Furthermore, stereotactic biopsy can be non-diagnostic or underestimate grading. Hence, there is a compelling need of new diagnostic biomarkers to avoid such invasive procedures. Several biological markers have been proposed, but they can only identify s...
UNLABELLED BACKGROUND The diagnosis of leptomeningeal metastasis (LM) in patients with solid tumors remains difficult. The usual diagnostic methods of cytomorphological assessment of cerebro-spinal fluid (CSF) and gadolinium enhanced MRI of the entire neuraxis lack both specificity and sensitivity. The Veridex CellSearch® technology has been designed for the detection of circulating tumor ce...
In twelve anaesthetised, ventilated dogs the effects of hypercapnia and pharmacologically induced arterial hypotension and hypertension on the interrelation between volume-pressure response (VPR) and cerebro-spinal fluid (CSF) pulse pressure were studied during continuous inflation of a supratentorial extradural balloon. Hypercapnia did not significantly affect the intracranial volume-pressure ...
