[Changing trends in illegitimate live births in the Czech Republic].

The authors analyze changes in the rate of illegitimate births in the Czech Republic. They find that "the slowly but fluently increasing percentage of illegitimate live births..

[Alpha-fetoprotein in umbilical cord blood and hyperbilirubinemia in normal neonates].

In a group of 154 mature normal neonates the authors recorded significantly higher mean alpha-fetoprotein values in children with hyperbilirubinaemia (higher than 205 mumol/l) than in other neonates. The differences were observed also in children of equal gestation age. Development of hyperbilirubinaemia is more probable and indication for phototherapy is significantly higher in neonates with alpha-fetoprotein levels in umbilical blood above 100 mg/l and these infants must be carefully observed.

[Results of phototherapy in neonatal hyperbilirubinemia using green and blue light].

In a group of normal newborns with birth weights of 2500 g and more treated on account of hyperbilirubinaemia the authors recorded a significantly shorter period of decline of serum bilirubin in 40 children with blue light phototherapy than in 40 children with green light phototherapy. The period of decline of bilirubinaemia with green light phototherapy did not differ on average from the period of spontaneous decline recorded in a group of 40 normal neonates with untreated hyperbilirubinaemia.

[Hyperbilirubinemia in normal neonates].

In a group of 13,449 neonates with a birth weight of 2500 g or more and without an incompatible constellation with the mothers in the Rh and ABO system in 17.7% of the children a rise od serum bilirubin above 205 mumol/l was found and 5.3% of the children were treated by phototherapy.
