In a study carried out in 100 cases of premature birth in Section ''A'
' of the Department of Gynecology and Obstetrics of the University of
Turin, the authors report a perinatal mortality rate of 5.4%. Perinata
l morbidity was found to be very high (68.2%). These findings-which ar
e perfectly in line with those reported in the literature-explain why
premature birth is one of the most important topics of research in mod
ern obstetrics.
