Anencephalus in Scotland 1961-72.
Data relating to the incidence of anencephalus for the 12-year period 1961-72 were abstracted from the Statistical Reviews of the Registrar General for Scotland. It was shown that considerable geographical variation is still apparent with the highlands having, in general, the lower incidences. In comparison with the earlier study of Edwards (1958), there were some changes: the incidence in the ...
متن کاملPotato blight and anencephalus in Scotland.
The theory has recently been put forward by Renwick (1972a) that anencephalus and spina bifida are caused by exposure early in pregnancy to potatoes which are affected by blight or are imperfect for other reasons. In support of this, a temporal correlation was claimed to exist between the severity of blight and the frequency of anencephalus, largely because of a strong correlation between the a...
متن کاملSeasonal variation in anencephalus in Canada.
A study of the monthly numbers of stillbirths and of deaths due to anencephalus in Canada from 1954 to 1962 showed a weak tendency to a winter excess of affected births. The seasonal trend was more marked in the Prarie provinces and in Quebec than elsewhere; the maximum rate of anencephalus occurrence was in October to December in the Prairies and in British Columbia, and in January to March in...
متن کاملInfective endocarditis: a survey of cases in the South-East region of Scotland, 1969-72.
The incidence and characteristics of infective endocarditis were studied in a defined community over a four-year period. Seventy-eight cases were found, giving an incidence of 16 cases permillion per year. The commonest presenting features were those of infection; 53% had cardiac failure and 37% evidence of emboli when first seen. Twenty-three cases occurred on rheumatic heart valves, 13 on val...
متن کاملAnencephalus: a changing sex ratio.
The sex ratio of infants born with certain congenital abnormalities diverges widely from unity. There is evidence that these sex ratios vary from place to place and in different races (Gittlesohn and Milham, 1962; Emanuel, 1972). Stocks (1970) has shown that within 25 countries of largely European stock there is a close positive correlation between the divergence of the sex ratio of congenital ...
