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

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.

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

A case of new PCDH12 gene variants presented as dyskinetic cerebral palsy with epilepsy.

J Hum Genet 2018 Jun 19;63(6):749-753. Epub 2018 Mar 19.

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

MANAGEMENT OF ENDOCRINE DISEASE: Management of Cushing's syndrome during pregnancy: solved and unsolved questions.

Eur J Endocrinol 2018 Jun 9;178(6):R259-R266. Epub 2018 Mar 9.

Aix-Marseille Université, Institut National de la Santé et de la Recherche Médicale (INSERM), U1251, Marseille Medical Genetics, Marseille, France.

With fewer than 200 reported cases, Cushing's syndrome (CS) in pregnancy remains a diagnostic and therapeutic challenge. In normal pregnancies, misleading signs may be observed such as striae or hypokalemia, while plasma cortisol and urinary free cortisol may rise up to 2- to 3-fold. While the dexamethasone suppression test is difficult to use, reference values for salivary cortisol appear valid. Read More

Severe Fetal Distress and Placental Damage might be Associated with High Troponin I (cTnI) Levels in Mothers.

Am J Case Rep 2018 Feb 21;19:194-198. Epub 2018 Feb 21.

Department of Experimental and Clinical Biomedical Sciences, University of Florence, Florence, Italy.

BACKGROUND Troponin I is the gold standard for the diagnosis of adult acute coronary syndrome. Although it is known that a hypoxic fetus may produce cTnI, fetal cTnI passage in maternal blood has never been documented. CASE REPORT We report a case where the rise of cTnI in the blood of a pregnant woman was not related to maternal heart disease. Read More

EXIT (ex utero intrapartum treatment) in a growth restricted fetus with tracheal atresia.

Int J Pediatr Otorhinolaryngol 2018 Feb 9;105:72-74. Epub 2017 Dec 9.

Division of Maternal Fetal Medicine, Emory University, Atlanta, GA, USA.

Congenital high airway obstruction syndrome (CHAOS) encompasses a heterogeneous group of pathologies leading to poor lung development and difficulty oxygenating the newborn after delivery. While previously uniformly fatal, the ex utero intrapartum therapy (EXIT) procedure has provided a method to treat these patients and provide an airway to potentiate survival. We present a patient diagnosed prenatally with CHAOS secondary to tracheal atresia complicated by severe intra-uterine growth restriction (IUGR) who was successfully delivered via an EXIT procedure at 33-weeks.

Identification of compound heterozygous variants in the noncoding RNU4ATAC gene in a Chinese family with two successive foetuses with severe microcephaly.

Hum Genomics 2018 01 25;12(1). Epub 2018 Jan 25.

UMR1078 "Génétique, Génomique Fonctionnelle et Biotechnologies", INSERM, EFS - Bretagne, Université de Brest, CHRU Brest, Brest, France.

Background: Whole-exome sequencing (WES) over the last few years has been increasingly employed for clinical diagnosis. However, one caveat with its use is that it inevitably fails to detect disease-causative variants that occur within noncoding RNA genes. Our experience in identifying pathogenic variants in the noncoding RNU4ATAC gene, in a Chinese family where two successive foetuses had been affected by severe microcephaly, is a case in point.

Consensus definition and essential reporting parameters of selective fetal growth restriction in twin pregnancy: a Delphi procedure.

Ultrasound Obstet Gynecol 2019 Jan;53(1):47-54

Department of Obstetrics and Gynecology, University Medical Center Groningen, University of Groningen, Groningen, The Netherlands.

Objectives: Twin pregnancy complicated by selective fetal growth restriction (sFGR) is associated with increased perinatal mortality and morbidity. Inconsistencies in the diagnostic criteria for sFGR employed in existing studies hinder the ability to compare or combine their findings. It is therefore challenging to establish robust evidence-based management or monitoring pathways for these pregnancies. Read More

Motorizing and Optimizing Ultrasound Strain Elastography for Detection of Intrauterine Growth Restriction Pregnancies.

Ultrasound Med Biol 2018 03 9;44(3):532-543. Epub 2018 Jan 9.

Department of Biomedical Engineering, National University of Singapore, Singapore. Electronic address:

Intrauterine growth restriction is a prevalent disease in pregnancy in which placental insufficiency leads to 5 to 10 times higher mortality and lifelong morbidities. The current detection rate is poor, and recently, ultrasound strain elastography (USEL) was proposed as a new diagnostic technique. Currently, placental USEL uses maternal subcutaneous fat as the reference layer, but this is not ideal as fat tissue stiffness can vary widely between subjects. Read More
