Rupture of intracranial aneurysm during computerized tomography.

A computerized tomographic (CT) scan was performed on a patient with a suspected paraseller mass. Coincident with contrast injection, an unusual and distinctive "starburst" pattern appeared in the right parasellar region and was associated with sudden deterioration in the patient's condition. Subsequent CT and necropsy confirmed a ruptured aneurysm at the suspected site with a large subarachnoid hemorrhage. To our knowledge, this unusual CT picture of a rupturing intracranial aneurysm has not been previously illustrated.

A clinical study of delirium in children and adolescents.

A group of 33 children and early adolescents with acute central nervous system disorders of toxic, metabolic, traumatic, and other types were studied in the hospital. They were compared with a matched control group, also in the hospital, who had no central nervous system disorder. Methods of study for both groups included neurological examination; mental status; electroencephalographic tracings (using developmental norms established here); neuropsychological and other techniques carried out during the acute disorder and repeated after its subsidence. Results distinguished significantly between the two groups, confirming the findings of Romano and Engel with adults. Some interesting differences related to childhood developmental level were noted: the occurrence of regression, the persistence of mild perceptual-motor and other abnormalities for some weeks even after complete recovery (involving potential learning difficulties), and the finding of a significant number of "soft" neurological signs in the control group.

Evaluation of one dimensional profile scans with a whole body counter--82bromide space in liver cirrhosis: concise communication.

One dimensional profile scans with a whole body counter are refocused with a linear space invariant filter in the frequency domain, 'Hanning' window and inverse system transfer function. Artifacts are eliminated in a way that a clinically applicable method is developed. Topographic information is achieved with the highly energetic nuclide 82bromide. The bromide space (extracellular volume) in patients with liver cirrhosis (n = 9) compared to normal subjects (n = 10) is increased most in the upper abdominal thoracic region.

Bilateral oculomotor paralysis due to neurosyphilis.

Bilateral third nerve paresis attributed to neurosyphilis has not been documented in the absence of associated neurological deficits. We describe a patient with isolated bilateral third nerve paresis, positive serological findings in blood and cerebrospinal fluid, CSF pheocytosis, and increased protein content. Resolution of these abnormalities occurred when the patient was treated with penicillin.

The effect of saline and hyperoncotic dextran infusion on canine ileal salt and water absorption and regional blood flow.

1. The unidirectional Na and H2O fluxes, vascular pressures and total and absorptive site blood flows in the canine ileum were determined before and during I.V. saline infusion and subsequent I.V. infusion of hyperoncotic dextran. The intestinal perfusion solutions were isotonic saline or isotonic saline and mannitol, but the effects of I.V. saline or I.V. hyperoncotic dextran infusion were generally the same for both luminal solutions. 2. Continuous I.V. infusion of saline caused a continuous increase in the unidirectional flux of Na and H2O into the ileal lumen, an increase in total blood flow, and an increase in venous pressure. 3. The net absorption of Na and H2O was decreased by I.V. saline infusion. 4. The unidirectional fluxes of Na and H2O out of the lumen, arterial pressure, and absorptive site blood flow were not affected by I.V. saline infusion. 5. I.V. hyperoncotic dextran infusion reversed most of the effects of saline infusion. 6. The unidirectional fluxes of Na and H2O into the lumen were significantly correlated with Starling forces during I.V. saline infusion. 7. It was concluded that intestinal transport of salt and water was subject to regulation by physical forces at the capillary level.
