A successful pregnancy in a patient with secondary hypertension caused by adrenal adenoma: a case report.

BMC Pregnancy Childbirth 2019 Apr 3;19(1):116. Epub 2019 Apr 3.

Department of cardiology, West China Hospital, Sichuan University, Chengdu, China.

Background: Secondary hypertension is a rare complication in pregnancy that causes poor outcomes, such as preeclampsia, premature delivery, intrauterine growth retardation, stillbirths, spontaneous abortion or intrauterine death. Cushing's disease caused by an adrenal adenoma is rare during pregnancy and may be overlooked by obstetricians and physicians, but can lead to hypertension, diabetes mellitus and an increased risk of fetal and maternal morbidity. Approximately 200 cases have been reported in the literature. Read More

Aspirin pre-treatment modulates ozone-induced fetal growth restriction and alterations in uterine blood flow in rats.

Reprod Toxicol 2019 01 5;83:63-72. Epub 2018 Dec 5.

Environmental Public Health Division, National Health & Environmental Effects Research Laboratory, Office of Research and Development, U.S. Environmental Protection Agency, Research Triangle Park, NC, USA.

Prenatal exposure to ozone has been linked to low birth weight in people and fetal growth restriction in rats. Clinical recommendations suggest use of low dose aspirin to lower risk of preeclampsia and intrauterine growth restriction in high-risk pregnancies, yet its utility in mitigating the postnatal effects of gestational ozone exposure is unknown. The present study investigated the possibility of low dose aspirin to mitigate the effects of ozone exposure during pregnancy. Read More

Pravastatin and-L-arginine combination improves umbilical artery blood flow and neonatal outcomes in dichorionic twin pregnancies through an nitric oxide-dependent vasorelaxant effect.

Vascul Pharmacol 2018 11 4;110:64-70. Epub 2018 Jun 4.

Division of Women and Children's Health, King's College London, United Kingdom. Electronic address:

The increase in fetal and neonatal morbidity and mortality associated with twin pregnancies correlates with an increased risk of preterm delivery, low birth weight, and intrauterine growth restriction (IUGR). Although the pathogenesis of IUGR is unclear and thus management remains a major challenge, feto-placental blood vessels are compromised, and altered umbilical blood flow is observed. In this pilot observational study we investigated the effects of pravastatin plus l-arginine on umbilical artery (umb art) blood flow. Read More

Department of Obstetrics, Gynecology and Oncology, Second Faculty of Medicine, Medical University of Warsaw, Warsaw, Poland.

Ultrasonography, with its detailed imaging of the fetus, is very widely used in obstetrics. The primary aim of ultrasound scanning in pregnancy is to limit the risk of obstetric complications by early detection of abnormalities, such as intrauterine growth restriction and macrosomia. Currently, morphometric formulae are used for estimating fetal weight. Read More

Quantitative assessment of placental perfusion by three-dimensional power Doppler ultrasound for twins with selective intrauterine growth restriction in one twin.

Eur J Obstet Gynecol Reprod Biol 2018 Jul 17;226:15-20. Epub 2018 May 17.

Department of Obstetrics and Gynecology, University of Tennessee Health Science Center, Memphis, TN, USA.

Objective: We quantitatively assessed placental perfusion using three-dimensional (3D) power Doppler ultrasound for twins with selective intrauterine growth restriction (sIUGR) in one twin.

Study Design: A prospective cross-sectional study was performed for 104 normal monochorionic diamniotic twins and 30 twins with sIUGR. Twins with sIUGR were divided into two groups: in group I (19 twins), both fetuses had continuous forward end-diastolic blood flow in the umbilical artery; in group II (11 twins), the smaller fetus had a loss or a reverse end-diastolic blood flow in the umbilical artery, but the larger fetus had continuous forward end-diastolic blood flow.

Department of Obstetrics and Gynecology, Clinical Sciences Lund, Lund University, Skane University Hospital, S-221 85, Lund, Sweden. Electronic address:

The growth-restricted fetus in utero is exposed to a hostile environment and suffers undernutrition and hypoxia. To cope with the stress, the fetus changes its physiological functions. These adaptive changes aid intrauterine survival; however, they can lead to permanent functional and structural changes that can contribute to the development of serious chronic diseases later in life.

Fetal Medicine Foundation fetal and neonatal population weight charts.

Ultrasound Obstet Gynecol 2018 07 30;52(1):44-51. Epub 2018 May 30.

Medway Maritime Hospital, Gillingham, UK.

Objective: To develop fetal and neonatal population weight charts. The rationale was that, while reference ranges of estimated fetal weight (EFW) are representative of the whole population, the traditional approach of deriving birth-weight (BW) charts is misleading, because a large proportion of babies born preterm arise from pathological pregnancy. We propose that the reference population for BW charts, as in the case of EFW charts, should comprise all babies at a given gestational age, including those still in utero. Read More

R Townsend A Khalil

Best Pract Res Clin Obstet Gynaecol 2018 May 24;49:79-88. Epub 2018 Feb 24.

Fetal Medicine Unit, St George's University of London, 4th Floor, Lanesborough Wing, St. George's Hospital, London, SW17 0QT, UK; Molecular & Clinical Sciences Research Institute, St George's University of London, UK. Electronic address:

Twin pregnancies are more likely to be affected by fetal growth restriction (FGR), preterm birth and perinatal loss. The management of fetal growth restriction in multiple pregnancy, particularly where only one fetus is affected is complicated by the need to consider the interests of both twins. Selective growth restriction in monochorionic (MC) twins is a pathophysiological process distinct from FGR in dichorionic (DC) pregnancies and management demands an understanding of the monochorionic placental structure and interdependent fetal circulations.

Brain structural connectivity is known to be altered in cases of intrauterine growth restriction and premature birth, although the specific effect of maternal nutritional restriction, a common burden in human populations, has not been assessed yet. Here we analyze the effects of maternal undernutrition during pregnancy and lactation by establishing three experimental groups of female mice divided according to their diet: control (Co), moderate calorie-protein restriction (MCP) and severe protein restriction (SP). Nutritionally restricted dams gained relatively less weight during pregnancy and the body weight of the offspring was also affected by maternal undernutrition, showing global growth restriction.

Hyperelastic Mechanical Properties of Ex Vivo Normal and Intrauterine Growth Restricted Placenta.

Ann Biomed Eng 2018 Jul 6;46(7):1066-1077. Epub 2018 Apr 6.

Department of Biomedical Engineering, National University of Singapore, 9 Engineering Drive 1, #02-04, Singapore, 117575, Singapore.

Intrauterine Growth Restriction (IUGR) is a serious and prevalent pregnancy complication that is due to placental insufficiency and IUGR babies suffer significantly higher risks of mortality and morbidity. Current detection rate for IUGR is generally poor and thus an alternative diagnostic tool is needed to improve the IUGR detection. Elastography, a non-invasive method that measures the tissue stiffness, has been proposed as one such technique. Read More

Maternal hemodynamics, fetal biometry and Doppler indices in pregnancies followed up for suspected fetal growth restriction.

Ultrasound Obstet Gynecol 2018 Oct;52(4):507-514

Fetal Medicine Research Institute, King's College London, London, UK.

Objectives: To assess whether, in a cohort of patients with a small-for-gestational-age (SGA) fetus with estimated fetal weight ≤ 10 percentile, maternal hemodynamics, fetal biometry and Doppler indices at presentation can predict the subsequent development of an abnormal fetal Doppler index or delivery of a baby with birth weight < 3 percentile.

Methods: This was a prospective observational cohort study conducted at a specialist clinic for the management of pregnancies with a SGA fetus at King's College Hospital, London, UK. The study population comprised 86 singleton pregnancies with a SGA fetus, presenting at a median gestational age of 32 (range, 26-35) weeks. Read More

Best Pract Res Clin Obstet Gynaecol 2018 May 1;49:53-65. Epub 2018 Mar 1.

Johns Hopkins Center for Fetal Therapy Department of Gynecology & Obstetrics Johns Hopkins University Baltimore, MD, 21287, USA. Electronic address:

A uniform approach to management of fetal growth restriction (FGR) improves outcome, prevents stillbirth, and allows appropriately timed delivery. An estimated fetal weight below the tenth percentile with coexisting abnormal umbilical artery (UA), middle cerebral artery (MCA), or cerebroplacental ratio Doppler index best identifies the small fetus requiring surveillance. Placental perfusion defects are more common earlier in gestation; accordingly, early-onset (≤32 weeks of gestation) and late-onset (>32 weeks) FGR differ in clinical phenotype. Read More

Department of Pediatric Neurology, Miyagi Children's Hospital, Sendai 989-3126, Japan.

Here we report a Japanese patient with new compound heterozygous truncating variants in the PCDH12 gene. As compared to the previously reported families who had congenital microcephaly, intrauterine growth retardation, intracranial calcification, and neonatal seizure associated with dysplasia of the midbrain-hypothalamus-optic tract, the present patient showed no midbrain-hypothalamus dysplasia or congenital/postnatal microcephaly, but dyskinetic cerebral palsy and severe intellectual disability as well as multifocal epilepsy. To understand phenotypic spectrum associated with PCDH12 variants, more reports are needed. Read More

Division of Molecular Genetics, Institute for Comprehensive Medical Science, Fujita Health University, Toyoake, Japan.

Thanatophoric dysplasia and achondroplasia are allelic disorders caused by a constitutively active mutation in the FGFR3 gene. Because thanatophoric dysplasia is a lethal disorder and achondroplasia is non-lethal, they need to be distinguished after ultrasound identification of fetal growth retardation with short limbs. Accordingly, we have developed a noninvasive prenatal test using cell-free fetal DNA in the maternal circulation to distinguish thanatophoric dysplasia and achondroplasia. Read More
