... which they were based. An example is the decades’ old practice of recommending a 4-mg (4,000-µg) supplement of folic acid to women who are at risk for recurrent neural tube defect (NTD) during pregnancy. This recommendation was based on findings from a randomized clinical trial in 1991. Since...

... Context and Objective: Considering the lack of accurate and up-to-date information available about neural tube defects (NTDs) in France, the purpose of this study was to review clinical and epidemiological data of NTDs and to evaluate the current efficiency of prenatal diagnosis in Alsace (northeastern...

Deprest Introduction: We review the characteristics and prenatal choices of patients recently evaluated for neural tube defects (NTD) at two...

...Elliot C. Pennington; Kristy L. Rialon; Beatrice Dionigi; Azra Ahmed; David Zurakowski; Dario O. Fauza Purpose: The proportions of select stem cells in term amniotic fluid have been shown to correlate with the type and size of experimental neural tube defects (NTDs). We sought to determine...

...F.E. Bredaki; L.C. Poon; C. Birdir; D. Escalante; K.H. Nicolaides Objective: To assess the potential value of maternal serum alpha-fetoprotein (AFP) at 11–13 weeks’ gestation in early screening for fetal neural tube defects (NTDs). Methods: Maternal serum AFP at 11–13 weeks’ gestation was measured...

...Dhara B. Dhaulakhandi; Seema Rohilla; Kamal Nain Rattan The failure of closure of the neural tube during development leads to malformations called neural tube defects (NTDs). The most common neural malformations in humans include anencephaly, encephalocele, exencephaly, craniorachischisis spina...

... for by differences in median weights of the two ethnic groups. Although these results would suggest that Hispanic women at risk for a fetus with a neural tube defect (NTD) may be missed when cut-offs derived from a Caucasian population are used, in fact, that was not the case in our screening population. However...

...T.K.A.B. Eskes Prepregnancy counselling is efficient in cases of chronic maternal disease, selection of medication and avoiding bad life habits. A new policy is the use of folic acid in the periconceptional period for the purpose of reducing the chance of having a baby with neural tube defects (NTD...

... was verified postnatally. Conclusion: Craniorachischisis is a rare and severe form of neural tube defects (NTDs). The majority of currently known cases of mouse craniorachischisis have been found to result from disturbance of a single molecular signaling cascade, called planar cell polarity pathway (PCP...

... of a neural tube defect (NTD) in a country where abortion is illegal. Method: The study population consisted of cases referred to and delivered at Hospital de Clínicas de Porto Alegre, diagnosed between January 1993 and December 2001. The diagnosis of severe hydrocephalus was based on a lateral ventricular...

...Hüseyin Özyurt; Aylin Totan; Şemsettin Şahin; Cumhur Kılınç; Sadık Söğüt; Ömer Akyol Objective: The present study was aimed to evaluate the alterations of maternal serum and amniotic fluid OH- proline levels in neural tube defects (NTD). Methods: 38 patients and 23 control subjects were selected...

...Rosa Maria Ibba; Maria Angelica Zoppi; Marcella Floris; Fabiola Manca; Carolina Axiana; Antonio Cao; Giovanni Monni Objectives: The risk of neural tube defects (NTDs) is negatively correlated with maternal folate levels in early pregnancy. Thalassemia carriers often have reduced red cell folate...

...Mathias B. Forrester; Ruth D. Merz Objective: To determine the influence of various factors on the prenatal diagnosis and elective termination of neural tube defects (NTDs) in Hawaii in 1986–1997. Methods: Data from a birth defects registry were analyzed and included 245 cases. Results: 74...
