[Scintigraphy of the bile ducts by means of the Tc-99m-acid N-(2,6 diethyl-acetanilide) iminodiacetic acid in pediatrics].

Results with diethyl-IDA in the diagnosis of dilatation and obstruction of the bile ducts are reported. By comparison with methyl-IDA, the more rapid blood clearance and slower renal excretion of diethyl-IDA do not lead to interference on the part of the right kidney and ureter during the first 30' of scintiscanning. The preparation was employed in 15 subjects with persistent neonatal icterus and clinically suspected diseases of the hepatic bile ducts. Personal experience is cited for the view that, thanks to its almost exclusively biliary excretion and high bile concentration, 99mTc-labelled diethyl-IDA gives better visualisation of the bile ducts than the methyl-IDA complex.

[Behavior of the somatotropic hormone during neonatal exchange transfusion].

Plasma growth hormone values in newborns subjected to exsanguinotransfusion for haemolytic disease were compared with those in a sample group of neonates with physiological icterus. Basal HGH values in infants with EF were significantly higher than those noted in the controls, whereas blood sugar values were within the limits of normal. These results suggest that enhanced HGH secretion attributable to the stress of exsanguinotransfusion is accompanied by direct stimulation of hypothalamic cells producing GH releasing factor on the part of bilirubin.
