[Very preterm births (22-26 WG): from the decision to the implement of palliative care in the delivery room. Experience of Rennes University Hospital (France)]. / Naissances très prématurées (22 à 26 SA) : de la décision à la mise en œuvre des soins palliatifs en salle de naissance. Expérience du CHU de Rennes (France).

OBJECTIVES: After the establishment of a palliative care protocol (PC) in the delivery room, study how the postnatal management decision was taken and in particular how PC was developed. MATERIAL AND METHODS: Retrospective analysis of births between 22 and 25+6 WG, in Rennes University Hospital, during 21 months. RESULTS: Twenty-seven women meeting the criteria gave birth to 32 live children. Decision making (intensive care or PC) was fast but shared with the parents, mainly on the criterion of the term. The delivery was vaginal for 24 children. Thirteen children were resuscitated. Nineteen children received comfort care, their life was less than 3 hours, 18/19 were supported by their parents. CONCLUSION: The management of these births is consistent with current recommendations, decisions are individualized but often informally. The secondary prognostic criteria could be better taken into account. Obstetrical and pediatric management is consistent. The PC protocol is fairly well used but the collective decisions should be more formally organized and transcribed more accurately in the records, the requirements for analgesics should be based on clinical assessments.

[A case of uterine rupture discovered in the postpartum period]. / Un cas de rupture utérine découvert en post-partum.

Because of the increasing number of cicatricial uteruses, uterine ruptures are likely to become more frequent. However, few cases discovered in the postpartum period are described in literature. Our case report describes a uterine rupture, which occurred during a quick vaginal delivery, in a patient with previous cesarian section. The diagnosis has been made few days after delivery, the patient presenting pelvic pain and fever. We do not disagree with the principle to check uterine scar only when suspicion of rupture, but we should keep in mind that in case of endometritis in the postpartum period, with cicatricial uterus, it would be necessary to research uterine rupture by fitted imaging.

Embryology of neural tube defects: information provided by associated malformations.

OBJECTIVES: To get information about embryologic mechanisms of neural tube defects (NTD), by studying the associated malformations. METHODS: Eighty three cases of NTD, seen at the prenatal diagnosis unit of Rennes University Hospital (France) between May 1999 and December 2002, were retrospectively studied. Cases with chromosomal anomalies (5/83), cases without available karyotype or pathologic examination were excluded. 24 spina bifida, and 27 cephalic forms (anencephalies, exencephalies, and encephaloceles) were thus analyzed. RESULTS: Only 22/51 cases (43%) were strictly isolated NTD. Anomalies of tissues arising from neural crests were noted in 8/51 fetuses (16%), midline or lateralization anomalies in 12/51 (24%), and anomalies of mesoblastic tissues in 17/51 (33%). An already known syndrome was found in 4/51 cases (8%). CONCLUSION: NDT are more extensive congenital damages that would suggest the restrictive terminology. That prompts to assess cautiously prenatal diagnosis of NTD, and to get detailed pathological examination after termination of pregnancy.

[Problems raised by the gynaecologic management of women with BRCA 1 & 2 mutations]. / Problèmes posés par la prise en charge gynécologique des femmes porteuses d'une mutation germinale des gènes BRCA 1 & 2.

Breast and ovarian cancer occur more frequently in young women with BRCA 1 &2 mutations (respective cumulative risks from 37 to 85% and 10 to 20%), and raise specific gynaecologic problems as prophylactic surgery and hormonal treatments. Two medical files from 2 sisters with BRCA 1 mutation (exon 11) are presented and the authors discuss the therapeutic options chosen. BRCA 1 & 2 tumour suppressor genes seem to play a major role in the repair of cellular damages inducing by the estrogenic proliferative signal. The prophylactic mastectomy is effective for the breast cancer prevention but its acceptance is low. The oophorectomydecreases the ovarian risk (knowing the occurrence of peritoneal carcinomatosis in 1.8% of cases) and currently the breast cancer risk (RR = 0.47) by the hormonal privation: the hormone replacement therapy does not seem to increase the breast cancer risk in the small series published. The HRT is possible in women with BRCA mutation under medical supervision and if the doses of hormones are light. The first results concerning the chemoprevention by Tamoxifen are encouraging (RR = 0.38) in these patients, but more studies are needed. The oral contraception exerts an uncertain effect against ovarian cancer, but possibly enhances the breast cancer risk in this group of women (RR = 3.3). The management of women with BRCA mutation is varying according to their own priorities, which can change during their life.
