[Study of circulation of cerebro-spinal fluid using indium 111 DTPA. Apropos of 300 cases].
A study of the C.S.F. circulation by intrathecal injection of radioactive tracers has become a common technic of neurological exploration. Among the molecules used at present, Indium111 DTPA has numerous advantages for this type of study. It is a chelating agent, the renal clearance of which is rapid and which has no toxicity at the dose injected. Indium111 is a product of the cyclotron and the physical period (2.8 days) is compatible with the duration of the examination. Finally the dose of radioactivity delivered by this isotope is less than that Iodine131, Technetium99m and Ytterbium169. In normal subjects after injection by the lumbar route, the average biological period measured by external counting lies between 20 and 28 hours. A study of the circulation of the C.S.F. is particularly useful in patients suspected of hydrocephalus. It permits finer diagnosis and shows the indications and type of by pass operation that may be neccssary. A marked increase in the biological period of Indium111-DTPA seems to be a good indication for such an operation. Our experience of 300 patients has shown the interest of the use of Indium111-DTPA which now seems to be the best radio-isotope for the study of the subarachnoid space.
[Relation between plasma catecholamines, the severity of the liver disease and hemodynamics in patients with cirrhosis].
Plasma noradrenaline and adrenaline concentrations were measured in 75 patients with cirrhosis in order to attempt to correlate these concentrations and liver failure and hemodynamic changes. The increased noradrenaline concentration was not correlated with the degree of liver failure estimated by Pugh's classification, with the cause of cirrhosis, with the presence of acute alcoholic hepatitis or with the presence of ascites. Adrenaline concentration was higher in cirrhotic patients with acute alcoholic hepatitis than in those without these lesions. Noradrenaline concentration was significantly correlated with heart rate, wedged hepatic venous pressure and renal blood flow. Noradrenaline concentration was also negatively correlated with stroke volume and adrenaline concentration was negatively correlated with cardiac output and stroke volume. These findings confirm the relationships between portal hypertension, sympathetic hyperactivity and renal function in patients with cirrhosis.
