Estriol serum levels, neonatal vitality and stromal villous edema were studied in diabetic pregnancies. The average serum estriol levels in diabetic patients whose placentas had villous edema was 26.45 +/- 9.16 ng/ml. This value was significantly lower than that of the diabetic patients without
The goal of this study was to determine if the multiple marker screening test (maternal serum alpha-fetoprotein, unconjugated estriol, human chorionic gonadotrophin, and maternal age) detects fetal Turner syndrome or just cystic hygroma/hydrops. Multiple marker screening tests from 4 groups were
OBJECTIVE
To estimate the detection rate for 45,X pregnancies through second-trimester screening using maternal serum alpha-fetoprotein, human chorionic gonadotropin and unconjugated estriol.
METHODS
Twenty-two cases of 45,X were ascertained through a cytogenetics database and an additional 51 cases
OBJECTIVE
To compare second-trimester maternal serum analyte values in Down syndrome pregnancies with, and without, hydrops fetalis.
METHODS
Seven hydropic and 85 non-hydropic Down syndrome pregnancies were identified among women with positive second-trimester maternal serum screening results.
Two receptor systems for oestrogens have been demonstrated in the uterus: the cytosol-nuclear receptor system and the eosinophil receptor system. It has been proposed that the cytosol-nuclear receptor system mediates the genomic response to oestrogens in the uterus, while the eosinophil receptor
Although the incidence of Down syndrome increases with advancing maternal age, the use of maternal age alone as a screening tool results in the identification of only about one third of the cases of fetal Down syndrome. Screening tools for Down syndrome (trisomy 21) have become more sensitive and
OBJECTIVE
The objective of this study was to determine the ability of biochemical analytes to identify adverse outcomes in pregnancies with Turner syndrome.
METHODS
Maternal serum and amniotic fluid (AF) marker concentrations were measured in 73 singleton pregnancies with Turner syndrome (10-22
OBJECTIVE
To develop an artificial intelligent diagnostic system with neural networks to determine genetical disorders and fetal health problems by using maternal serum markers ('Triple Test') and maternal age.
METHODS
A total of 112 pregnant women were referred to Fetal Medicine Unit of Hacettepe
OBJECTIVE
Our purpose was to examine the ability of the multiple-marker screening test (maternal serum alpha-fetoprotein, human chorionic gonadotropin, unconjugated estriol, and maternal age) to detect fetal Turner syndrome.
METHODS
We reviewed 27,282 screening tests performed at our institution
OBJECTIVE
The combination of maternal serum alpha-fetoprotein, unconjugated estriol, and human chorionic gonadotropin levels and maternal age has been used to increase the sensitivity of screening for fetal Down syndrome and trisomy 18 in early-second-trimester pregnancies. We hypothesized that a
OBJECTIVE
The purpose of this study is to determine the effectiveness of second-trimester maternal serum screening for Down syndrome as a screening test for fetal hemoglobin (Hb) Bart's disease among an unselected population.
METHODS
A secondary analysis of a large prospective database (20 254
Advances in technology have made possible the prenatal diagnosis and treatment of female fetuses with classical congenital adrenal hyperplasia due to 21-hydroxylase deficiency. Hormonal measurement of 17-hydroxyprogesterone, androstenedione, testosterone and 21-deoxycortisol and HLA typing and DNA
Smith-Lemli-Opitz (SLO) syndrome is an autosomal recessive disorder comprised of recognizable facial abnormalities, growth retardation, and multiple congenital anomalies, commonly involving genitalia, second and third toe syndactyly, and cleft palate. The condition is associated with
The study was carried on 25 primigravidae with severe pre-eclamptic toxaemia (PET) and 19 normal pregnancies as a control group. 15 cases of PET were treated by 600 mg. progesterone daily for variable duration between one and six weeks. Daily blood samples were assayed for progesterone,
