    Quantitative Measurement of PARD3 Copy Number Variations in Human Neural Tube Defects.
    Cell Mol Neurobiol 2017 Jun 16. Epub 2017 Jun 16.
    Capital Institute of Pediatrics, No.2, Yabao Road, Chaoyang District, Beijing, 100020, People's Republic of China.
    Although more than 200 genes are known to be related to neural tube defects (NTDs), the exact molecular basis is still unclear. Evaluating the contribution of copy number variation (CNV) might be a priority because CNV involves changes in the copy number of large segments of DNA, leading to phenotypic traits and disease susceptibility. Recent studies have documented that the polarity protein partitioning defective 3 homolog (Pard3) plays an essential role in the process of neural tube closure. Read More

    Secondary Myelitis in Dermal Sinus Causing Paraplegia in a Child with Previously Normal Neurological Function.
    Case Rep Neurol Med 2016 6;2016:8918954. Epub 2016 Dec 6.
    Department of Pediatrics, Kilimanjaro Christian Medical Centre, Moshi, Tanzania; Department of Internal Medicine, Kilimanjaro Christian Medical Centre, Moshi, Tanzania; Radboud University Medical Centre, Nijmegen, Netherlands.
    Neural tube defects result from failure of neural tube fusion during early embryogenesis, the fourth week after conception. The spectrum of severity is not uniform across the various forms of this congenital anomaly as certain presentations are not compatible with extrauterine life (anencephaly) while, on the other hand, other defects may remain undiagnosed as they are entirely asymptomatic (occult spina bifida). We report a child with previously normal neurological development, a devastating clinical course following superinfection of a subtle spina bifida defect which resulted in a flaccid paralysis below the level of the lesion and permanent neurological deficits following resolution of the acute infection and a back closure surgery.

    Using state and provincial surveillance programs to reduce risk of recurrence of neural tube defects in the United States and Canada: A missed opportunity?
    Birth Defects Res A Clin Mol Teratol 2016 Nov;106(11):875-880
    College of Public Health, University of South Florida, Tampa, Florida.
    Background: Once a woman has had a fetus or infant affected with a neural tube defect (NTD), the risk of recurrence is approximately 3%. This risk can be significantly reduced by folic acid supplement consumption during the periconceptional period; however, this requires women at risk to be adequately informed about the appropriate dosage and timing of supplement intake before planning another pregnancy. As birth defects surveillance programs are tasked with identifying and documenting NTD-affected pregnancies and births, they are in a unique position to support recurrence prevention activities.

    Neural tube defects (NTDs) are a group of severe congenital malformations, induced by the combined effects of genes and the environment. The most valuable finding so far has been the protective effect of folic acid supplementation against NTDs. However, many women do not take folic acid supplements until they are pregnant, which is too late to prevent NTDs effectively. Read More

    Genomic approaches to the assessment of human spina bifida risk.
    Birth Defects Res 2017 Jan;109(2):120-128
    Dell Pediatric Research Institute, Department of Nutritional Sciences, The University of Texas at Austin, Austin, Texas.
    Structural birth defects are a leading cause of mortality and morbidity in children world-wide, affecting as much as 6% of all live births. Among these conditions, neural tube defects (NTDs), including spina bifida and anencephaly, arise from a combination of complex gene and environment interactions that are as yet poorly understood within human populations. Rapid advances in massively parallel DNA sequencing and bioinformatics allow for analyses of the entire genome beyond the 2% of the genomic sequence covering protein coding regions. Read More

    Background: Many illnesses demonstrate seasonal and geographic variations. Pharmacovigilance is unique among public health surveillance systems in terms of the clinical diversity of the events under surveillance. Since many pharmacovigilance signal detection methodologies are geared towards looking for increased frequency of spontaneous adverse drug event (ADE) reporting over variable time frames, seasonality of ADEs may have implications for signal detection.

    Maternal Antenatal Bereavement and Neural Tube Defect in Live-Born Offspring: A Cohort Study.
    PLoS One 2016;11(9):e0163355. Epub 2016 Sep 29.
    Department of Clinical Epidemiology, Aarhus University Hospital, Aarhus N, Denmark.
    Background: Maternal emotional stress during pregnancy has previously been associated with congenital neural malformations, but most studies are based on data collected retrospectively. The objective of our study was to investigate associations between antenatal maternal bereavement due to death of a close relative and neural tube defects (NTDs) in the offspring.

    Methods: We performed a register-based cohort study including all live-born children (N = 1,734,190) from 1978-2008. Read More

    Geographic clusters of congenital anomalies in Argentina.
    J Community Genet 2017 Jan 19;8(1):1-7. Epub 2016 Aug 19.
    ECLAMC (Latin American Collaborative Study of Congenital Malformations) at CEMIC (Center for Medical Education and Clinical Research), Buenos Aires, Argentina.
    Geographical clusters are defined as the occurrence of an unusual number of cases higher than expected in a given geographical area in a certain period of time. The aim of this study was to identify potential geographical clusters of specific selected congenital anomalies (CA) in Argentina. The cases were ascertained from 703,325 births, examined in 133 maternity hospitals in the 24 provinces of Argentina. Read More

    Birth defects and neonatal morbidity caused by teratogen exposure after the embryonic period.
    Birth Defects Res A Clin Mol Teratol 2016 Nov 11;106(11):935-939. Epub 2016 Aug 11.
    Departments of Pediatrics and Genetics, University of North Carolina at Chapel Hill, Chapel Hill, North Carolina.
    Background: Pharmaceutical pregnancy exposure registries seek to evaluate temporal associations between drug exposures and adverse outcomes, particularly congenital anomalies. These registries record observed associations that may or may not be causally-related to the exposure. Most major congenital malformations (i. Read More

    Check the Head: Emergency Ultrasound Diagnosis of Fetal Anencephaly.
    West J Emerg Med 2016 Jul 5;17(4):460-3. Epub 2016 Jul 5.
    West Virginia University School of Medicine, Department of Emergency Medicine, Morgantown, West Virginia.
    Background: Early pregnancy complaints in emergency medicine are common. Emergency physicians (EP) increasingly employ ultrasound (US) in the evaluation of these complaints. As a result, it is likely that rare and important diagnoses will be encountered. Read More

    A 2015 global update on folic acid-preventable spina bifida and anencephaly.
    Birth Defects Res A Clin Mol Teratol 2016 Jul;106(7):520-9
    Center for Spina Bifida Prevention, Department of Epidemiology, Rollins School of Public Health of Emory University, Atlanta, Georgia.
    Background: Spina bifida and anencephaly are two major neural tube defects. They contribute substantially to perinatal, neonatal, infant, and under-five mortality and life-long disability. To monitor the progress toward the total prevention of folic acid-preventable spina bifida and anencephaly (FAP SBA), we examined their global status in 2015. Read More
