[Herpetiform dermatitis and atopic dermatitis].

History data and clinical pattern were analysed in 33 children with herpetiform dermatitis (DH) and in 34 children with atopic dermatitis (DA). The differences are stressed between DH and DA as which it is frequently misdiagnosed, which is the cause of delayed treatment in DH (in the studied group 2.8 years on the average).

[Renin activity and aldosterone level in the plasma of children with lipoid nephrosis].

In 16 children with steroid-responsive nephrotic syndrome (with minimal changes in the glomeruli) the plasma renin activity and aldosterone level were determined during recurrence of the nephrotic syndrome at the stage of oedema increase (FEN alpha 0.25%) and in early period of remission. Plasma renin activity was raised in all cases suggesting presence of hypovolaemia.

Value of bile acid determination for the diagnosis of neonatal jaundice.

Serum concentrations of bile acids and bilirubin, and activity of alanine transferase and alkaline phosphatase as well as bile acid and bilirubin levels in duodenal contents were determined in 90 infants aged 1-44 weeks (including 49 under 10 weeks of age) admitted to hospital for prolonged jaundice. Infants with extrahepatic cholestasis were found to have statistically higher serum bile acid and bilirubin concentrations. Oral administration of cholestyramine produced a statistically significant decrease in serum bile acids and bilirubin in infants with intrahepatic cholestasis under 10 weeks of age.
