[Report on threatened premature labor: etiology, management, results].

The studies on the aetiological factors of a premature delivery constitute an old fear of obstetricians and epidemiologists. However, they remain confused and the very definition of prematurity is among the first sources of confusion. There are many therapeutic methods considered as preventive. Their efficacy is debatable whilst their secondary effects are obvious. In this article, the authors report the results of a retrospective study of observations of patients who presented threats of premature labour and analyzed the epidemiological aspects, the aetiological factors and the therapeutic methods. It seems important to consider the risk factors in order to prevent premature labour. A decrease in the use of betamimetics and an increase in that of therapies said to be of replacement does not seem to be accompanied by a relative increase in the incidence of prematurity.

[Evolution of the parietal incision in cesarean sections].

This concerns a multicenter study including 51 centers of the North, Picardy and Champagne areas, 35 public institutions and 16 private institutions. This study was carried out on 7,216 records of Caesarean sections, collected between 1978 and 1983. The objective of this study was to specify maternal and fetal morbidity in Caesarean sections. In this study, the authors attempted to establish a correlation between this morbidity and the parietal incision, as well as compare the responsibility of each of the two incisions that were performed: midline infraumbilical and Pfannenstiel's incision. From a neonatal standpoint, they have demonstrated that the type of parietal incision has no bearing on the condition of the child at birth, in spite of a slightly longer extraction time in the Pfannenstiel incision. From a maternal standpoint, they found a similar number of wall abscesses and wound dehiscence. Abdominal wall hematomas are slightly more frequent with the Pfannenstiel incision and this difference is significant. The reservations formulated concerning transverse incisions and especially the Pfannenstiel incision do not appear to be justified.

[Evaluation of ultrasonography. Apropos of a continuous series of 1,000 pregnancies].

2,648 sonograms were performed in a continuous series of 1,000 patients, all of whom had delivered in the department between March 1, 1988 and September 1, 1988; pregnancies resulting in a spontaneous miscarriage, extra-uterine pregnancy, therapeutic abortion as well as invasive sonographies, are excluded. Most patients underwent two or three sonograms during their pregnancy. 74 per cent of the requests come from specialists. The main indications are either systematic (67.7%) or result from early manifestations (25.1%). 12.6 per cent of the sonograms are performed before 12 weeks of amenorrhea, including 36.7 per cent performed systematically, and could be performed at a later date. 90 per cent of the term modifications were correctly indicated, and there were early manifestations in 60 per cent of the cases. 45.1 per cent of intra-uterine growth delays were detected and there were early manifestations in 50 per cent of the cases. 41.6 per cent of the malformations were diagnosed on sonograms. Renal malformations are easily recognized; this is not true of cardiac malformations. 96 per cent of the patients were justifiably reassured or worried. Ultrasonography presents a good sensitivity for term modifications, macrosomia, placental insertion anomalies. The sensitivity is less for intra-uterine growth delays and fetal malformations.

[Role of the thyroid in first-trimester miscarriage].

In case of maternal hypothyroidism, the number of miscarriages is higher and reaches 50% in this multicenter study. Several hypotheses are advocated in order to explain this frequent occurrence: the most remarkable is that as substitute treatment is very effective and decreases noticeably the risk of abortion. In case of maternal hypothyroidism, the frequency of abortions in this study reaches 35% before the disease is diagnosed and this figure is not modified (35%) after the diagnosis is made and the treatment initiated. Finally, in case of goiter or euthyroid nodules, there is also a relatively high number of spontaneous abortions. Therefore, there are still a number of unknown factors regarding the role of dysthyroidisms in spontaneous first-trimester abortions.

[Practical problems posed by toxoplasmosis during pregnancy].

The occurrence of toxoplasmosis during pregnancy raises numerous problems. Determination of the time of the maternal infection is the first problem since we know that the frequency and gravity of fetal involvement vary according to the term of the pregnancy. Then, with information obtained from prenatal diagnostic tests (sonogram, amniocentesis, fetal blood sampling), it is important to recognize infected fetuses and advocate a management which goes beyond therapeutic abortion. Finally, the final problem is the follow-up of these children; in fact, after all these diagnostic and therapeutic measures, it is unfortunate that many children become lost to follow-up after the first year.

[Study of the choice between sampling of the chorionic villi and the amniotic fluid in prenatal diagnosis].

We are reporting the results of a 21-month study during which 653 couples were seen in consultation at the prenatal diagnostic center of the University Hospital in Amiens, referred by their physician. 171 patients presented a theoretical term under 11 weeks of amenorrhea, for whom the choice between chorionic villi biopsy or amniotic fluid tap was possible. The different situations and results are compared for each method. The rate of fetal death was 5.4 per cent for chorionic villi biopsy and 1.5 per cent for amniotic fluid tap.
