Respiratory distress syndrome and the value of amniotic fluid phospholipids in predicting such complications before birth.

The amniotic fluid study of 80 samples from 40 patients, obtained by amniocentesis between 28 and 40 weeks of pregnancy, was carried out. It was noted that L/S (Lecithin/Sphingomyelin) ratio was significantly different at 36-38 weeks of pregnancy when compared with values in pregnancies of less than 36 weeks gestation (P less than 0001). No cases of RDS occurred when the L/S ratio was mature 4 or more. A brief review of recent developments in etiology of RDS are also presented.

Fetal exsanguination associated with antepartum hemorrhage.

Fetal bleeding in utero is infrequent. It is usually life-threatening but can be treated successfully in most cases if recognized early. Four cases are described and it is suggested that screening for fetal blood be done in all instances of antepartum hemorrhage.
