Sixty-seven premature deliveries were included in the aminophylline group and 75 in the control group. The perinatal death rate was 7.1% in the aminophylline group ...
Lundström U - - 1979
Prematurity has traditionally been connected with thrombocytopenia, although this is unlikely to be associated with prematurity itself but rather with serious illnesses in such infants. Platelet counts were measured in 117 healthy preterm infants with birthweights less than 2000 g, who were followed up from 2 weeks to 6 months. ...
Valderrama E - - 1979
A premature infant with segmental hypoplasia of one kidney is reported. Since 1929 when Ask-Upmark first reported this renal anomaly and its association with hypertension, the nature of the lesion has remained in doubt. The question whether it is acquired post-natally or whether it is a developmental mal-formation has not ...
