Our purpose was to evaluate whether maternal and fetal hepatocyte growth factor (HGF) concentrations in pregnancies with small for gestational age (SGA) infants are different from those in pregnancies with appropriate for gestational age (AGA) infants. Maternal and fetal circulating HGF concentrations were compared between 55 pregnancies with AGA infants and 16 pregnancies with SGA infants at b...
OBJECTIVE We investigated whether the concentration of the glycoprotein fetuin A is altered in the second trimester amniotic fluid of trisomy 21 pregnancies compared with euploid pregnancies. METHODS 25 pregnancies with an extra chromosome 21 were matched for maternal and gestational age with 25 pregnancies with normal karyotype. Levels of fetuin A in amniotic fluid were measured by a commerc...
In order to study the possible role of nitric oxide (NO) in the human placenta, we measured the concentration of its stable metabolite nitrite (NO2-) in the placentas of women with normal pregnancies and those from pregnancies complicated by intrauterine growth restriction (IUGR) with or without fetal hypoxia. We have measured nitrites by the Griess reaction in 15 placentas from IUGR pregnancie...
OBJECTIVE To determine the risks of stillbirth and neonatal complications by gestational age in uncomplicated monochorionic and dichorionic twin pregnancies. DESIGN Systematic review and meta-analysis. DATA SOURCES Medline, Embase, and Cochrane databases (until December 2015). REVIEW METHODS Databases were searched without language restrictions for studies of women with uncomplicated twin...
Background: Prediction of adverse perinatal and postnatal outcomes could be possible by using ultrasound Doppler evaluation, however there are some controversies regarding this issue in the literature. The goal of present study was to evaluate predictive value of Doppler indices in single and twin pregnancies during second trimester. Materials and Methods: This prospective study was conducted i...
Recurrent hydatidiform mole is defined as episodes of two molar pregnancies in a female. Often, complete moles onlyderive androgenic nuclear genome. We described two cases with repeated molar pregnancies attempted to preventfuture episodes by performing intracytoplasmic sperm injection (ICSI) and preimplantation genetic diagnosis (PGD)to assess genetic disorders. The first pat...
Introduction Ovarian pregnancy is an uncommon variant of ectopic pregnancy and diagnosis is a clinical challenge. Its frequency has been reported as 1 in 2100 to 1 in 7000 pregnancies(1). Among women who use IntraUterine Device (IUD), 4.3% of all pregnancies are ectopic pregnancies and of these, one tenth is ovarian pregnancies(2,3). Here we report three cases of spontaneous ovarian pregnancy s...
Tests of coagulation, fibrinolysis, and platelet function were performed in 17 patients with intact molar pregnancies. Women with intact molar pregnancies had higher fibrinogen factor VIII, and fibrinogen degradation products, concentrations and lower prothrombin, factor X, plasminogen, and plasminogen activator concentrations than controls with normal pregnancies. They also had reduced platele...
