212 out of 2806 women who delivered in the Haguenau Maternity had a period of amenorrhoea markedly longer than 42 weeks, when the menstrual cycle was 28 +/- 8 days. 39 of the 212 pregnancies, which means 18 per cent of the infants, showed signs of postmaturity and in these there was an excess of fetal distress. Those children who were born after pregnancies which were theoretically "prolonged" but did not show signs of postmaturity did not suffer neonatal distress any more than those children born at term. Having scans of uterine growth makes one come to the conclusion that these are not really prolonged pregnancies.
The best results in screening for subclinical cancer of the cervix are given by cytological studies. The authors in reviewing their experience in this method of screening studied the result of 15,000 smears which gave a diagnosis of 37 cases of intra-epithelial carcinoma of the cervix, which means 1 case of carcinoma in situ diagnosed in every 400 smears. Although the technique is very simple it has to be carried out according to strict criteria at the time of taking the smear, of fixing it immediately and of staining it. There is a group of patients who are at high risk about the age of forty, when there is a marked influence due to parity. But only a systematic policy will bring about diagnosis of pre-invasive carcinoma in cases where the cervix is clinically healthy. The cytology is usually characteristic, though the diagnosis may be difficult during pregnancy, or when hormone contraception is being used or when there is a trichomonas infection present. This explains why we find false positives in 0.03 per cent of cases in this study and false negatives in 0.03 per cent of cases. Their rarity means that the method is 99.94 per cent reliable. Finally, the cervical smear gives an opportunity for studying the vaginal microbial flora as well as the cyto-hormonal state.
The authors re-emphasize that the sure diagnosis of carcinoma of the cervix depends on histology; having considered a series of 15,000 smears in an article on cytological screening for carcinoma of the cervix. They show that the main prop of this histological examination should definitely be conisation. They furthermore prepare an inventory of the different possible methods of treatment of intra-epithelial carcinoma, stating for each method the advantages and disadvantages of the method. Their attitude to treatment is conservative, and they believe that conisation in every case is sufficient when complete removal of the in situ lesion is carried out whatever the age of the patient is. They state the limits of this method and define clearly the contra-indications for such a scheme of treatment, which can only be carried out routinely with the absolutely necessary cooperation of a cytology laboratory and faultless histology.
