Tube Closure

Neural tube defects (NTD) have been the object of more intense epidemiologic study than any other kind of birth defect. This is in part because of their ready recognition at birth (and, in recent years, before birth) and in part because their consequences are usually catastrophic: they kill or they cripple. Regarding their cause, no single genetic or environmental agent has been identified (or is likely to be) and a multifactorial basis is assumed. If failure of neural tube closure results from the additive effects of several adverse factors, removal or correction of any one might shift the developmental balance across the threshold from NTD to normality.

Tube Closure

Abstract Congenital anomalies are one of the primary causes of infant mortality and disability in the world. Neural Tube Defects (NTDs) are the most typical type of birth defect resulting from the failure of Neural tube closure. In this retrospective hospital-based study, the data of the children affected byneural tube defects (NTDs) were analyzed. Prevalence of Hydrocephalous, Myelomeningocele (MMC), Encephalocele, Lipo MMC, Meningocele, Spina Bifida Occulta among children with more or less than one year of age and their occurrence in males and females was studied. The frequency of occurrence of cases of neural tube defects was significantly less among all the congenital disabilities, i.e., 5% of total cases studied. The prevalence of myelomeningocele, hydrocephalous, and Encephalocele was higher than other types of NTDs. This study concludes that the prevalence of hydrocephalous and myelomeningocele in this area raises a concern to have more research of their etiology.

ObjectivesSex differences in prevalence of neural tube defects (NTDs) have previously been recognised; however, the different susceptibility of men and women have not been examined in relation to the effects of folic acid (FA) supplementation. We hypothesised that FA may have a disproportionate effect that alters the sex-specific prevalence of NTDs.SettingData from two time points, before (2003–2004) and after (2011–2016) the start of the supplementation programme, were obtained from a population-based birth defect surveillance programme among five counties in northern China. All live births (28 or more complete gestational weeks), all stillbirths of at least 20 weeks’ gestational age and pregnancy terminations at any gestational age following the prenatal diagnosis of NTDs were included.ParticipantsA total of 25 249 and 83 996 births before and after the programme were included respectively.Primary and secondary outcome measuresThe prevalence of NTDs by sex and subtype, Male:female rate ratios and their 95% CI were calculated.ResultsOverall, NTDs were less prevalent among men than among women (rate ratio (RR) 0.92; 95% CI 0.90 to 0.94), so was anencephaly (RR 0.77; 95% CI 0.73 to 0.81) and encephalocele (RR 0.75; 95% CI 0.61 to 0.92), while spina bifida showed a male predominance (RR 1.10; 95% CI 1.05 to 1.15). The overall prevalence of NTDs decreased by 78/10 000 in men and 108.7/10 000 in women from 2003 to 2004 to 2011 to 2016. There was a significant sex difference in the magnitude of reduction, being greater in women than men, particularly for anencephaly.ConclusionsThe prevalence of NTDs decreased in both sexes after the implementation of a massive FA supplementation programme. While female predominance was observed in open NTDs and total NTDs, they also had a greater rate of decrease in NTDs after the supplementation programme.

Lipomyelomeningocele, a congenital spine defect, is presented as skin-covered lipomatous tissue that attaches to the cord in different ways according to its subtypes. Unlike other types of neural tube defects, the exact cause of this birth defect has not been confirmed yet, but it is proposed to be a multifactorial disease with involvement of both genetic and environmental factors. The authors describe identical twins with lipomyelomeningocele of the same subtype and location without any familial history of similar abnormality. Therefore, the same genetic and/or environmental risk factors could have played a part in their condition.

Abstract Background : Intrauterine development can be considered as normal development as well as abnormal development. Abnormal development commonly called birth defects occur because of interference of normal development from genetic disorders, environmental factors and the combination of both genetic and environment factors during the critical period of embryogenesis. The present study aimed to evaluate the prevalence and patterns of birth defects at birth in Southwestern Ethiopia. Methods : Institutions based cross-sectional study design was used. Six hospitals were selected from the existing hospitals in southwestern Ethiopia purposively based on case load. The study was conducted from September 2011 to December 2015 during which 45,951 deliveries were attained. All records of births that were occurred in the selected hospitals during the study period were identified from medical records, to locate the birth defect records. Results : Twenty-one different birth defects were recorded. Of these, 49.6 % of the birth defects recorded were Anencephaly and Hydrocephalus. Five types of birth defects namely: Anencephaly (25.0%), Hydrocephalus (24.6%), Spinal bifida (13.1%), Meningomyelocele (7.1%), and Umbilical hernia (4.8 %) accounted about three-fourth (75%) of all recorded birth defects. The present study revealed that the prevalence of the birth defects at birth was found to be 5.5 per 1000 births. Among twenty one birth defects identified in this study, the neural tube defects were the most frequent with prevalence rate of 4.1 per 1000 birth followed by gastrointestinal defects (0.7 per 1000 births) Conclusions: As compared to other study, the prevalence of birth defect identified in the present study was found to be higher. The neural tube defects were the most prevalent with the frequency of 4.05 cases per 1000.The present study also identified that nearly equal proportions of birth defect occurred among males and females newborns. The majority of the mother who gave birth to birth defects was younger than 35 years old. As the birth defect was found to be a main cases of infant mortality and morbidity, there need to an urgent interventions to control the cases.

Specific Mechanism

Elucidating the cause of disease is often not easy and may require answers to many questions. Perhaps the most important questions have been rather simply stated in verse by Rudyard Kipling.1 I keep six honest serving men; (They taught me all I knew) Their names are What and Why and When and How and Where and Who. In terms of neural tube defects, many of these servants of Mr Kipling have provided valuable epidemiologic clues as to the cause of neural tube defects (NTDs),2 but the specific mechanism responsible for this disabling birth defect has so far escaped definition.
