13. Estudo do cariotipo constitucional e dos tecidos envolvidos na lesão de crianças portadoras de defeito do tubo neural (DTN) por meio de analise citogenetica convencional e FISH
The association between chromosomal abnormalities, specially aneuploidies and neural tube defects (NTDs) is well known, principally when NTD is not the only malformation present. Recently, research in animal models, using fluorescence in situ hybridization (FISH) identified aneuploidy in neural tissues. The aims of this work were to identify the frequency of

14. Anencephaly with diaphragmatic hernia in sibs.
Two sibs who both had anencephaly and diaphragmatic hernia are reported. The type of diaphragmatic defect seen in anencephaly may differ from the defect seen in other babies. It is important to perform a necropsy in anencephaly.

15. Differences between the events preceding spina bifida and anencephaly.
It is usually held that there is a time continuum in the formation of monoxygotic (MZ) twins which is indexed by their placentation, running from dichorionic to monochorionic diamniotic to monochorionic monoamniotic and conjoined pairs. There is good evidence that this continuum is characterised by a continuum of predisposition to anencephaly, slightly raise

16. Anencephaly: a retrospective analysis in Singapore. 1976 to 1980.
Records of 93 cases of anencephaly from three maternity hospitals in Singapore between 1976 and 1980 were analysed. The incidence was 0.54 per 1000 births. No significant correlation between anencephaly and local seasonal conditions could be found for Singapore.

17. Changing trend of neural tube defects in eastern Turkey.
STUDY OBJECTIVE--The aim was to study the relationship between birth prevalence of neural tube defect (including anencephaly) in Eastern Turkey before and after the Chernobyl disaster. DESIGN--This was a prospective study of time trends in live births and stillbirths over the years 1985-1990. Medical and sociodemographic data were recorded for the mothers. S

18. Anencephaly and potato blight in the Republic of Ireland
National potato tuber blight scores in the Republic of Ireland for the years 1961-70 were ascertained and evaluated in relation to incidence of anencephalic births in the following years. No significant relationship between annual tuber blight scores and incidence of anencephaly one year later could be demonstrated. Examination of the records of a maternity

19. Congenital malformations associated with anencephaly and iniencephaly.
The necropsy reports of 294 cases of anencephaly and 50 cases of iniencephaly have been examined, and a tubulated list of associated malformations produced. Cases were divided by sex and the presence or absence of spina bifida. Forty-one per cent of the series had other malformations, and other malformations were more common in those cases with spina bifida

20. Neural tube defects in New South Wales, Australia
Cases of spina bifida cystica, encephalocele, and anencephaly occurring over a 9-year period, 1965 to 1973, in New South Wales, Australia, were identified. A low frequency of 1·1 for spina bifida and encephalocele (SB) and 0·9 for anencephaly (A) was found.

21. A family showing apparent X linked inheritance of both anencephaly and spina bifida.
A family is reported which includes five males, two with spina bifida, two sibs with anencephaly, and one with both high and low spinal lesions. The affected subjects came from four sibships in three generations. The mode of inheritance of these neural tube defects is consistent with X linkage.

22. Screening for congenital neural tube defects in a high-risk area: an epidemiological perspective.
Data from the Glasgow Register of Congenital Malformations were used to investigate the extent of the recent decline in the prevalence of anencephaly and spina bifida, and the contribution of antenatal screening to it. Over the period 1974-85 inclusive, 303 pregnancies with an anencephalic foetus were diagnosed, representing an "adjusted" prevalence of 1.9 p

23. Concordance rates in twins for anencephaly.
New estimates are offered of the concordance rates in twins for anencephaly. In MZ pairs, the percentage which are concordant is about 7. This is significantly higher than (about three or four times) the value expected on the assumption that concordance is accounted for by raised recurrence rates within sibships. In DZ pairs, the data are less numerous and t

24. Sexes of affected cases in sibships containing two or more members with anencephaly or spina bifida.
A study has been made of the sexes of the affected within sibships containing two or more members with anencephaly or spina bifida (ASB). There is no clear evidence for variation between ASB-prone women in their propensity to bear affected cases of one sex rather than the other. It is suggested that the point should be regarded as open until further data hav
