background: differential diagnosis between complete hydatidiform mole, partial hydatidiform mole and hydropic abortion, known as hydropic placentas is still a challenge for pathologists but it is very important for patient management. objective: we analyzed the nuclear dna content of various types of hydropic placentas by flowcytometry. materials and methods: dna ploidy analysis was performed i...

In a case-control study of 73 women with and 141 women without spontaneous abortion, the authors determined the activity of the three principal caffeine-metabolizing enzymes--cytochrome P-4501A2 (CYP1A2), xanthine oxidase, and N-acetyltransferase 2--by measuring levels of caffeine metabolites in urine. After examining the effect of enzyme activity and different levels of caffeine intake, they c...

OBJECTIVE To analyse the spectrum of congenital heart malformations, the frequency of extracardiac malformations, and the proportion of chromosome aberrations among fetuses sent for necropsy. MATERIAL Necropsies were performed on 815 fetuses-448 induced abortions (55%), 220 spontaneous abortions (27%), and 147 stillbirths (18%)-during a seven year period (1991-97) in the department of patholo...

Background Congenital toxoplasmosis is an important cause of spontaneous abortion worldwide. However, there is limited information on detection and genotypic characterization of T. gondii in women with recurrent spontaneous abortion (RSA). The aim of this study is molecular detection and genotypic characterization of T. gondii in formalin-fixed, paraffin-embedded fetoplacental tissues (FFPTs) o...

Background: Recurrent spontaneous abortion (RSA) is a frequent reproductive problem, with three or more abortions affecting 1 to 2%, two or more abortions affecting up to 5% of women of reproductive age. Some polymorphisms are supposed to be etiology in this group.Vitamin D receptor (VDR) gene polymorphism seems to be a good ones to be searched due to their function on placenta. Materials and M...

AIMS To assess the role of Ki67 immunoreactivity in predicting the clinical progress of hydatidiform mole. METHODS Tissue from 87 hydatidiform moles, 11 normal first trimester placentas, 11 normal term placentas and 17 spontaneous abortions were examined for expression of Ki67 antigen, using the monoclonal antibody MIB1. RESULTS Ki67 immunoreactivity was significantly higher in the tissue f...

Background Cytogenetic study of reproductive wastage is an important aspect in determining the genetic background of early embryogenesis. Approximately 15 to 20% of all pregnancies in humans are terminated as recurrent spontaneous abortions (RSAs). The aim of this study was to detect chromosome abnormalities in couples with RSAs and to compare our results with those reported previously. Materia...
