Effect of lactulose on cerebral metabolism in patients with chronic portosystemic encephalopathy.

Cerebral blood flow and cerebral metabolism were studied in six patients with moderately severe portosystemic encephalopathy before and after a 10-day course of lactulose. As a result of therapy there was a mean increase in cerebral oxygen utilization but no changes in either mean glucose consumption or in mean cerebral blood flow. It appears therefore that the abnormalities in cerebral metabolism that have been previously described in patients with hepatic encephalopathy can be improved by the oral administration of lactulose.

[Gastric emptying of fluids and gallbladder contraction in non-ulcer dyspepsia].

Non-ulcer dyspepsia is a frequent clinical entity characterized by chronic upper gastrointestinal symptoms without organic lesions by radiology, sonography or endoscopy. We studied simultaneously the rate of gastric emptying and gallbladder contraction in 10 patients with non-ulcer dyspepsia and in 10 healthy controls after ingestion of 500 cc of isotonic saline, and 500 cc of a liquid mixed meal, hypercaloric and hyperosmotic. The measurements were done by direct real-time ultrasonic imaging in fasting and were repeated at regular intervals (15-30 minutes) after the liquid meal, until complete gastric emptying was established. We found with the liquid mixed meal, the patients with non-ulcer dyspepsia had a significant delay in gastric emptying and gallbladder hypokinesis with faulty contraction and slow refilling. Dynamic ultrasonographic studies are useful in patients with non-ulcer dyspepsia.

[Gastric emptying of different liquid test meals measured by ultrasonography].

The rate of gastric emptying of different liquid solutions was measured in 80 voluntary normal young male subjects (mean age 19.9 +/- 1.6 years) by direct real-time ultrasonic imaging. Multiple US scans were repeated at regular intervals (15-30 minutes) until complete gastric emptying was established, after ingestion of 500 cc of 8 different liquid test meals: isotonic saline, 50% glucose, 5% glucose, 40 g of proteins, 20 g of protein, 40 g of fat, 20 g of fat and mixed (carbohydrates, proteins and fat). Eight groups of ten subjects were studied, each one with a different test meal. Three types of gastric emptying were identified: slow (177 +/- 12 minutes) in subjects receiving 50% glucose, 40 and 20 grs of proteins and mixed test meals; intermediate (83 +/- 9 minutes) with 5% glucose, 40 and 20 g of fat; rapid (40 +/- 6 minutes) with isotonic saline. The mixed diet had the slowest emptying time (210 +/- 6 min). Our results are in accordance with published data regarding gastric motor physiology and demonstrates the usefulness of ultrasound in the study of gastric emptying of fluids.

[Ascaris hepatic abscess].

An 18 months old infant with hepatic abscesses was studied. Ultrasonographic examination of the liver revealed 2 abscesses in the right lobe of the liver containing elongated hyperecogenic structures compatible with ascaris lumbricoides. Antibiotic and antihelmintic treatment was followed by complete clinical recovery.
