Risk of birth defects in multiple pregnancies Frequency of monozygotic twins remains constant, while dizygotic twins become more frequent as maternal age increases. In these cases the risk that at least one fetus is aneuploid will be twice the maternal age risk for a singleton while the probability of both fetuses being involved is minimal. Dizygotic twins have a six fold increased risk that on...

BACKGROUND Couples are considered infertile if they do not conceive over a 12-month period of unprotected intercourse. Studies have shown that female causes accounted for between 25 to 37 percent of infertility worldwide (with larger proportions in sub-Saharan Africa and Southeast Asia) and male causes accounted for between 8 to 22 percent. Both male and female causes accounted for between 21 t...

background: in recent years, the high likelihood of the implantation of transferred embryos has led to an increase in the number of multiple pregnancies and consequently an increased risk of complications in fetuses and mothers. since the aim of infertility treatment is the birth of a healthy child while preserving the mother’s health, therefore, attempts should be made to avoid multiple pregna...

The pathogenesis of eclamptic convulsions remains unknown. Cerebral imaging suggests that cerebral abnormalities in eclampsia (mostly vasogenic edema) are similar to those found in hypertensive encephalopathy. However, cerebral imaging is not necessary for the diagnosis or management of most women with eclampsia. The onset of eclamptic convulsions can be antepartum (38–53%), intrapartum (18– 36...

to evaluate the value of random urinary protein creatinine ratio in prediction of 24h proteinuria in hypertensive pregnancies. method: random urine samples and routine 24h urine collections were collected from hypertensive pregnant women (n=100). reliability of random urinary protein-creatinine ratio was assessed by receiver operator characteristic (roc) curve to detect significant proteinuria ...
