Abstract: A [99mTc]RBC study in a 63-yr-old man showed intrahepatic lesions which initially had less activity than surrounding liver tissue. When viewed 3 hr later, these had "reversed" and the lesions revealed increased uptake of the radiolabeled red cells. Some extrahepatic areas showed the same pattern (these were in the mesentery of the small bowel). The lesions proved to be angiosarcomas. Hence, the behavior of labeled red cells in these angiosarcomas mimicked that in benign hemangiomas.
answer:
Hepatic angiosarcoma: mimicking of angioma on three-phase technetium-99m red blood cell scintigraphy.

question:
Abstract: To summarize the results: Bilirubin removal by hemoperfusion was successfully performed for the first time on a premature infant. The hemoperfusion caused no adverse effects on the clinical state of the infant. The bilirubin removed in 90 min--13 mg--indicates the existence of a large extravascular pool. Hemoperfusion is suggested for bilirubin removal from newborn babies, reducing the need for blood exchange with bank blood.
answer:
Bilirubin removal from a jaundiced premature infant by resin hemoperfusion.

question:
Abstract: Disseminated herpes simplex virus infection in a pregnant woman was successfully treated with acyclovir. Similar reported cases have suggested that acyclovir may be suitable for the treatment of disseminated or severe primary herpes in pregnant women.
answer:
Treatment of disseminated herpes simplex virus in pregnancy with parenteral acyclovir. A case report.
