[HIV virus infection and the perinatal period].

The incidence of HIV infection in women is increasing steadily. It has been estimated that between 30,000 and 40,000 French women in child-bearing age are seropositive for HIV. The risk of a seropositive woman transmitting the virus to her child is 40-50 p. 100, and the child will often develop AIDS during the first two years of life. For this reason, seropositive women should be dissuaded to become pregnant or the pregnancy should be interrupted within the normal time limits. Since no effective treatment of AIDS is available at present, prevention is of paramount importance. It consists of detecting seropositive women and above all fighting against intravenous drug addiction and spreading information on the risk of contamination by sexual intercourse.

[The interstitial pregnancy. Report of three observations (author's transl)].

The recent occurrence at the Port-Royal obstetrics and gynaecology center of three cases of interstitial pregnancy out of a total number of 208 ectopic pregnancies give us the opportunity to discuss the diagnosis and present management of the rarest form of tubal pregnancies. The diagnosis is always difficult. Nowadays, thanks to the use of echography and especially of laparoscopy, interstitial pregnancies can be detected earlier. Thus the precocity of the diagnosis should permit a conservative surgical treatment. Hysterectomy should not be considered but in very special cases.

[The current role of microsurgery and in vitro fertilization in the treatment of tubal infertility].

Tubal sterility is an important cause of sterility in the couple. Its treatment has been revolutionised, firstly by the progress in microsurgery and, more recently, by the current progress in in vitro fertilisation. Consequently, the gynecologist must have a very good knowledge of sterility in the couple and of tubal pathology. The authors report the results of 400 microsurgical operations performed in the Maternity department of the Port-Royal hospital and compare these results with those of in vitro fertilisation. In the light of these results, they then attempt to define the therapeutic indications which depend on a very precise investigation of the condition of the tubes. Microsurgery and in vitro fertilisation constitute complementary approaches in cases which are difficult to evaluate.

[Contact embryoscopy (author's transl)].

Prenatal diagnosis based on anatomic definition of the fetus in utero is an difficult task, in the first trimester of pregnancy. The authors have recently introduced a new method : contact embryoscopy which consist in applying the optic piece of a contact hysteroscope (diameter of six millemeters) to the intact and translucent ovular membranes by the cervix. They have performed fifty embryoscopy prior to termination of pregnancy at 8 to 12 weeks. In 41 cases, they have seen the hands of fetus with the fingers. If this technic fails, it is possible, later, to use Echography and fetoscopy. The side-effects are discussed. Contact embryoscopy would be particularly useful in the detection of malformations of the extremities, for instance : chondro-ectodermal dysplasia (Ellis Van Creveld Syndrome) or ectrodactily.

[Tobacco and pregnancy (author's transl)].

The evil effects of tobacco on the health of those who smoke it have been emphasized broadly in the past few years, both in the public and in the medical press. The possible damage that can be done to those who are "passive" smokers has also been pointed out. Now the fetus is in the front row of these. That is why it is important to point out this fact. After a brief statement about the physio-pathology of the condition the authors review the literature and extract the following points which can be ascribed to the use of tobacco: -- lowering of the birth weight; -- considerable increase in risk of premature separation of the placenta; -- a negative correlation with the frequency of pre-eclamptic toxaemia. The authors point out the additional feature that the effect of tobacco can potentiate the effects of an associated pathological condition. Finally, they emphasize the methodological difficulties which account for the numerous discrepancies and uncertainties that still exist about the action of tobacco on pregnancy.
