Summary. A questionnaire concerning pregnant women's knowledge of, and attitudes to, serum alpha fetoprotein (AFP) screening for spina bifida was sent to all pregnant women receiving a health education leaflet on AFP screening who booked at the Birmingham Maternity Hospital in the first quarter of 1984. The majority said that they would accept the test, and subsequently did so. This suggests that low uptake of the test is not a result of patients' resistance, and the results indicated that the provision of early information about the test is likely to improve uptake and decrease anxiety. With the increasing clinical usefulness of the AFP test, routine screening of pregnant women with an 'opt-out' system is becoming clinically desirable, and the survey suggests that it would be acceptable to the patients. 相似文献

Summary. Fifty-nine patients presented with elevated concentrations of gonadotrophins and secondary amenorrhoea before the age of 35 years. Fifty-three underwent laparoscopic examination and primordial follicles were observed in 16. Two others had follicles as they later became pregnant and a third showed biochemical evidence of spontaneous ovulation. There were streak ovaries in 12, two with follicles and three others with chromosomal abnormalities, two being 47XXX and one XO/XX. Two other patients had only one ovary each but no follicles. Chromosomal abnormalities were detected in two further patients one being XO/XX and the other a recombinant. Six patients became pregnant, two of them twice, resulting in four term deliveries and four spontaneous abortions. Three other patients showed biochemical evidence of ovulation; one spontaneously, one after oestrogen therapy and the third after treatment with gonadotrophin releasing hormone analogue. 相似文献

Summary. In-vitro thyroid function tests are difficult to interpret in pregnancy because of, among other things, the effect of oestrogens on thyroid binding globulin (TBG) concentrations. In an attempt to clarify the position, serum concentrations of total thyroxine (T4 ), free T4 , TBG, T4 /TBG ratio, tri-iodothyronine (T3 ) and thyroid stimulating hormone (TSH) were measured. Total T4 and TBG concentrations rose to above the non-pregnant reference range by 20 weeks. The T4 /TBG ratio fell to hypo-thyroid values by 20 weeks but although the free T4 level was lower in the third trimester compared with values in the first and second trimesters, only a few subjects had hypothyroid values. The TSH values remained unchanged throughout pregnancy. The significance of these changes is discussed and reference ranges for these hormones at each trimester are provided. 相似文献
