Raised plasma polyamine concentrations in patients with severe head injury.

Intracranial pressure monitoring in patients with severe head injury.

Increased intracranial pressure (ICP) has an adverse effect on the clinical course of patients with severe head injuries. Direct intracranial measurement is the only method of knowing the precise ICP. At the Maryland Institute for Emergency Medical Services Systems, elevations in ICP are treated according to an aggressive protocol. Our experience with this protocol has led to the following conc...

Multivariate analysis of plasma enzyme profiles in severe head injury.

We followed the changes in the activities of four enzymes (aldolase, aspartate aminotransferase, creatine kinase, and lactate dehydrogenase) in plasma for four days after head injury. The progression of the changes differs significantly between survivors and nonsurvivors. Stepwise discriminant analysis, involving the four enzymes, allowed us to divide 81 to 92% of head-injured patients (n = 280...

Raised plasma concentrations of 3-methoxy-4-hydroxyphenylethyleneglycol in cirrhotic patients with or without hepatic encephalopathy.

We measured the plasma concentration of a centrally derived noradrenaline (NA) metabolite, 3-methoxy-4-hydroxyphenylethyleneglycol (MHPG), in 20 cirrhotic patients (eight with (group A) and 12 without (group B) hepatic encephalopathy (HE] and in 14 age matched healthy subjects to study if the central NA metabolism would be altered in liver cirrhosis patients, particularly in those with HE. The ...

Falsely raised plasma digoxin concentrations in liver disease.

Jugular venous and arterial concentrations of serum S-100B protein in patients with severe head injury: a pilot study.

The objective of this study was to analyse the temporal course of the jugular venous-arterial gradient of S-100B protein after severe head injury and the correlation between the absolute concentrations of serum S-100B protein and outcome, CT findings, and clinical variables. Fifteen patients were included in this pilot study. All patients were treated according to a standard therapy protocol ta...
