[Indications and results of autotransfusion. Normovolemic hemodilution in gynecology-obstetrics].
Considering the importance of haemorrhagic complications in gynaecology-obstetrics and the increasing fear of accidents during blood transfusion, the authors propose, from the literature and the study of 13 cases, a reflection on the indications of deferred autotransfusion (DAT) and of normovolemic haemodilution (NVH). In obstetrics, even if DAT has undoubtedly certain advantages (besides viral contaminations, appearance of allo-antibodies...), it can be indicated at present only for pregnant women exposed to a predictable risk of haemorrhage or for women with a rare blood group. In gynaecology, the authors have not found any significant advantages in our study as regards NVH associated with DAT. However, as in obstetrics, the technique is harmless, and no thrombo-embolic complications have been observed, even in women at high thrombotic risk. These methods are expensive and require qualified personnel. Their exact modalities and indications, as well as their medico-legal aspects, are yet to be defined.
[Value of cyclofenil in the inhibition of lactation. Efficacy compared to bromocriptine].
The inhibitory effects of cyclofenil and bromocriptine on lactation as well as FSH, prolactin and estradiol levels have been compared in control and treated females. The clinical activity of cyclofenil was lower than that of bromocriptine but was virtually free of side-effects. Cyclofenil and bromocriptine only presented similar hormonal effects at the 20th day ; this suggests that the mechanism of action of cyclofenil is more linked to secondary increases in estrogen levels than to a primary effect. Cyclofenil is of particular value in cases of vascular hypersensitivity yo ergot derivatives and for toxemic patients treated with beta-blockers.

Medications exposure during pregnancy. A study in a university hospital.
To collect informations about drugs prescribed during pregnancy in France we carried out a retrospective survey from august to december 1989. This study was based on a questionnaire at delivery for 225 women. Socio-economic status, obstetrical past history and patterns of prescribing medications were studied. 99.5% of the women were found to have used drugs during pregnancy with a mean of 6.84 medications per woman. There was no influence of age, geographic origins, number of previous pregnancies on drug consumption; socio-professional status was also found to have a poor correlation with drug intake. Patterns of prescribing were compared to those of a previous French study made in 1976: changing pattern of prescribing were found for progestatives, corticoids, neurotropes, aspirin and beta adrenergic agents. We also pointed out that self-administered drugs decreased from 25.9 to 17.9%. This evaluation supports the need of further epidemiological studies in our country.
