Vascular thrombosis is a harmful and rather frequent event in sick premature infants. Only recently has intracardiac thrombosis been described in preterm babies and virtually all the surviving cases are those treated surgically. We report the cases of two premature infants with intra-atrial thrombosis detected by cross-sectional echocardiography and successfully ...

Chorioamnionitis is both a clinical and a histopathologic diagnosis. The latter may be clinically silent, but it commonly accompanies reproductive casualty and premature birth. Satisfactory delineation of its pathogenesis is elusive. Detailed histologic study indicates that endometrial inflammation usually precedes that of the membranes. Evidence is accumulated that Ureaplasma urealyticum ...

A cytologically distinctive type of acute hyperoxemic injury of retinal neurons occurs in premature neonates. Ganglion cells in the central well-vascularized neonate retina are susceptible to excessive oxygen and this is expressed morphologically by karyorrhexis of their nuclei. We observed retinal neuronal necrosis in neonates who had hyperoxemia of greater ...
