INTRODUCTION: The occurrence of early abortion after amniocentesis is a serious problem in the fields of obstetrics and gynecology, and it is always important to discover the factors influencing this phenomenon. The incidence rate has been reported in different studies, even up to about 10%. So far, no studies have been conducted in Iran on the effect of amniocentesis and related complications on early abortion. The aim of this study was to determine the effects of amniocentesis and relevant complications on the incidence of early abortion in pregnant women undergoing amniocentesis...

METHODS: Retrospective study of all QUAD screens performed at a single center from 2013-2015. All QUAD screen performed between 15-21 weeks were included in the study. Exclusion criteria were patients without anatomy scans or delivery information...

OBJECTIVE: Bronchopulmonary dysplasia (BPD) is a serious complication associated with preterm birth. A growing body of evidence suggests a role for prenatal factors in its pathogenesis. Metabolomics allows simultaneous characterization of low molecular weight compounds and may provide a picture of such a complex condition. The aim of this study was to evaluate whether an unbiased metabolomic analysis of amniotic fluid (AF) can be used to investigate the risk of spontaneous preterm delivery (PTD) and BPD development in the offspring...

OBJECTIVE: We present prenatal diagnosis and molecular cytogenetic characterization of a recombinant chromosome 10 in a fetus associated with a paternal pericentric inversion. CASE REPORT: A 35-year-old woman underwent amniocentesis at 18 weeks of gestation because of an advanced maternal age. Amniocentesis revealed a karyotype of 46,XY,der(10)del(10) (q26.3)dup(10)(p11.2p15). She underwent repeat amniocentesis at 21 weeks of gestation and array comparative genomic hybridization revealed a 31...

OBJECTIVE: To present molecular cytogenetic characterization of an inverted duplication of proximal chromosome 15 [inv dup(15)] presenting as a small supernumerary marker chromosome (sSMC) associated with the inv dup(15) syndrome. CASE REPORT: A 35-year-old woman underwent amniocentesis because of advanced maternal age at 27 weeks of gestation, which revealed an sSMC that was confirmed by fluorescence in situ hybridization (FISH) to be derived from chromosome 15...

OBJECTIVE: We present prenatal diagnosis and molecular genetic analysis of mosaic trisomy 17 and a review of the literature of mosaic trisomy 17 at amniocentesis. MATERIALS AND METHODS: A 42-year-old woman underwent amniocentesis at 17 weeks of gestation because of advanced maternal age, which revealed a karyotype of 47,XX,+17[4]/46,XX[17]. Prenatal ultrasound findings were unremarkable. She underwent repeat amniocentesis at 20 weeks of gestation. Interphase fluorescence in situ hybridization (FISH), array comparative genomic hybridization, and quantitative fluorescent polymerase chain reaction assays were applied to uncultured amniocytes...

OBJECTIVE: We present molecular cytogenetic characterization of an Xp22.32→pter deletion and an Xq26.3→qter duplication in a male fetus with congenital malformations and maternal X chromosome pericentric inversion. MATERIALS AND METHODS: A 22-year-old woman underwent amniocentesis at 17 weeks of gestation because of an abnormal maternal serum screening result. Prenatal ultrasound revealed a hypoplastic left heart and short limbs. Amniocentesis revealed a karyotype of 46,Y,der(X) t(X;?)(p22...

Orofacial clefts are the most common congenital craniofacial anomalies and can occur as an isolated defect or be associated with other anomalies such as posterior fossa anomalies as a part of several genetic syndromes. We report two consecutive voluntary pregnancy interruptions in a nonconsanguineous couple following the fetal ultrasound finding of cleft lip and palate and posterior fossa anomalies confirmed by means of post-termination examination on the second fetus. The quantitative fluorescent PCR, the karyotype, and the comparative genomic hybridization-array analysis after amniocentesis were normal...

PURPOSE: The purpose of this study is to evaluate the incidence of maternal cell contamination (MCC) in the first few milliliters of amniotic fluid withdrawn during amniocentesis. METHODS: A prospective observational study was performed. The initial 2-3 ml of amniotic fluid withdrawn during amniocentesis was divided into direct analysis (uncultured) and cultured samples. A matching maternal buccal swab was obtained for MCC testing. MCC was determined by short-tandem repeat analysis...

INTRODUCTION: This study assessed the sensitivity of routine ultrasound examination for the detection of abnormal chromosomes and structural malformations in fetuses in the second trimester in a non-selected population. MATERIAL AND METHODS: Prenatal diagnoses of fetal abnormalities in 10 414 fetuses and newborns were reviewed and compared with all postnatal diagnoses of congenital abnormalities between 2006 and 2013. RESULTS: Overall, 243 fetuses and newborns had confirmed congenital abnormalities, with a prevalence of 2...

INTRODUCTION: We report the rare finding of recurrent periventricular pseudocysts (PVPC) in consecutive pregnancies in 4 families and their postnatal outcome. MATERIALS AND METHODS: We reviewed the databases of 3 large ultrasound units searching for the diagnosis of PVPC in 2 pregnancies of the same patient. RESULTS: The first case of recurrent PVPC was diagnosed in 2011 and since then 3 additional families were diagnosed (8 cases of PVPC all in all)...

Balanced translocation is a common structural chromosomal rearrangement in humans. Carriers can be phenotypically normal but have an increased risk of pregnancy loss, fetal death, and the transmission of chromosomal abnormalities to their offspring. Existing prenatal screening technologies and diagnostic procedures fail to detect balanced translocation, so genetic counseling for carriers remains a challenge. Here, we report the characteristics of chromosomal reciprocal translocation in 3807 amniocentesis cases...

Second-trimester amniotic fluid supernatant (AFS) contains cell-free fetal RNA (cffRNA) transcripts that can provide information about fetal gene expression. In a retrospective case-control study, we measured second-trimester fetal gene expression using cffRNA extracted from AFS in women who had spontaneous preterm birth (sPTB) <34 weeks and in women who delivered >37 weeks. We extracted cffRNA from AFS of women with singletons who had second-trimester genetic amniocenteses. Twenty-one gravidas who had sPTB and 21 term controls were matched 1:1 for maternal age, fetal sex, race, gestational age (GA) at the time of amniocentesis, and medication exposure...

OBJECTIVE: The aim of this study was to evaluate the amniotic fluid cathepsin-G concentrations in women with preterm prelabor rupture of membranes (PPROM) based on the presence of the microbial invasion of the amniotic cavity (MIAC) and/or intra-amniotic inflammation (IAI). METHODS: A total of 154 women with singleton pregnancies complicated by PPROM were included in this study. Amniotic fluid samples were obtained by transabdominal amniocentesis. Amniotic fluid cathepsin-G concentrations were assessed by ELISA...

OBJECTIVE: The linkage between 17q12 microdeletions, renal anomalies and higher risk for neuro-developmental disorders is well described in the literature. The current study presents prenatal diagnosis of normal-sized hyperechogenic fetal kidneys leading to the diagnosis of 17q12 deletion syndrome and autistic spectrum disorder. METHODS: Over a period of nine years in a single referral center, seven fetuses were diagnosed with hyperechogenic renal parenchyma and followed prospectively...

OBJECTIVE: To elucidate the factors that contribute to prolonged pregnancy and promote neonate survival in women with bulging fetal membranes. METHODS: A database was reviewed to identify women with singleton pregnancies who underwent amniocentesis on admission to determine amniotic fluid neutrophil elastase levels before 26 + 0 weeks gestation between July 2001 and January 2015. Following delivery, the placentas of these patients were examined for histologic chorioamnionitis...

In this article second trimester amniotic fluid biomarkers are measured for correlation with preterm delivery. One additional milliliter of amniotic fluid is collected during amniocentesis for dosages of IL-6, MMP-9, CRP and glucose levels, along with maternal serum CRP and glucose. MMP-9 and Il-6 levels were measured with the corresponding Human Quantikine(R) ELISA Kit (R&D systems) according to the instructions provided by the manufacturer. Cut-off values for AF MMP-9 and IL-6 were fixed by the kit sensitivity thresholds...
