[Perinatal pathology]

The study includes 965 cases of autopsies in premature and full term newborns comparing their pathology within the pre, intra and postnatal periods; the neonatal period was also divided into weeks. The results may be correlated from different parameters, pointing out susceptibility, risk, nature of the pathologic processes and their order of arrival within the stages mentioned. The suitable reason that may exist to explain the high index of anatomoclinical diagnoses, not correlated in this study, is analysed and it is believed that a knowledge of some of these problems may be useful to prevent and to manage them adequately within and outside our hospital units.
