The Developmental Origins of Human Adult Disease are thought to be secondary to a perturbation of the embryonic or fetal development, which leads to metabolic disorders such as diabetes or hypertension at adulthood. Maternal undernutrition or overnutrition, repeated glucocorticosteroids administered to the mother, or placental dysfunction are the most frequently considered causal factors. Therefore, it is necessary that the obstetrician is aware of these phenomena, as this knowledge may contribute to the prevention of adult diseases. Little is known yet, on the pathophysiological or epigenetic mechanisms that lead to theses observations, and more studies are needed both in humans and animal models. 相似文献

Objectives
To study immediate perineal and neonatal outcomes after instrumental rotational performed with Thierry's spatula among primiparous, and compare subsequent perineal tear with occiput posterior position delivery.Materials and methods
The study was performed from December 2005 to June 2006 at Paule-de-Viguier hospital (Toulouse university hospital) including all persistent occiput posterior vaginal deliveries among primiparous (49 patients). Mode of delivery was: 1) seven patients with spontaneous occiput anterior vaginal delivery (14.3%); 2) seven patients with rotational extraction using spatula with occiput anterior delivery (30.6%); 3) twenty-seven patients with instrumental extraction and occiput posterior delivery (55.1%). Maternal and fetal parameters were studied prospectively.Results
Spatula was performed for failure of progress in 71.4% of cases (n = 30) and for no reassuring fetal status in 28.6% of cases (n = 12). In “rotational group”, only one perineal tear was observed (Third degree) (6.6%) versus seven in “occiput posterior extraction group” (26%) with three severe perineal lacerations. Neonatal superficial lesions are frequent (26,6% after rotation versus 11.6% after occiput posterior extraction). None severe traumatic tears were observed.Conclusion
Instrumental rotation using Thierry's spatula seems to be less deleterious for maternal perineum than occiput posterior extraction, without increasing neonatal complications. Theses preliminary results have to be confirmed by more important prospective works. 相似文献3.

Calcium channel blockers of the dihydropyridin's family have been associated with the onset of an acute pulmonary edema when they are used as a treatment of preterm labor. We report here four cases of pulmonary edema in pregnant women treated with nicardipine (Loxen) for preterm labor. The physiopathology of pulmonary edema, the pharmacology of calcium channel blockers of dihydropyridin's family and the detailed analysis of our cases and those of the literature make us discuss of the role of these agents and associated population and risk factors in such complication. 相似文献

The French legislation about gamete donation imposes anonymity between the donor and the demanders, in reference to the principles of protection of the human dignity that are applied in other fields of biomedicine. We are here wondering about this choice: does this obligation really protect the human rights that are one of the ethical bases of law? At the time the French law was written, anonymity in gamete donation was inherited from the practice of the French CECOS but it has now become controversial. Many European countries have opened the access to the genetic origins. There is no evidence for this practice to be an efficient protection of the respect of human body and the disinterested nature of donation. Concerning gametes, it seems that it protects a social object, the parental project, but that it has no influence on the protection of parenthood, filiation, and the concept that humankind is not only biological. At last, we analyse the most important human rights documents to assume the hypothesis that anonymous gamete donation, although not violating the human rights, is an implement for Foucault's biopower, far from protecting the ethical foundations of human dignity. 相似文献

ObjectiveTo search if the prosthetic kits bring an interest, other that financier.Materials and methodAuthors have counted 5 firms presenting the varied kits. The Prolift™ kit with synthetic pre- cut mesh made of polypropylene, standardized needle, cannulas and protective devices of recovery of mesh arms in 3 versions, anterior, posterior and total. Perigee™ and Apogee™ systems in a synthetic version (IntePro™) and a biological version (InteXen ++LP™) matched of specific needles for the different obturator passages and infra coccygeus. The Avaulta™ kit declines in a biosynthetic version and a hybrid version with a specific needle for its anterior kit and an other for its posterior kit. The Biomesh® Soft system presents a polypropylène mesh posed on a multi pattern sheet to carve following dots with a share of 3 needles according to the type of arm passage ended by a recuperator thread. The Nazca POP Repair System, in its anterior version claims to be able to correct in the same time a urinary incontinence by pre-pubic arms. The polypropylene mesh is perforated and is had with the help a needle for its anterior and posterior kit. Authors have been interested in the research of studies on prosthesis with and without kit.ResultsThe Prolift™ kit contains the alone prosthesis having been evaluated without (TVM) and with kit. Authors remind results of two studies, understanding 684 cases without kit and 110 cases with kit. The rate of early per and postoperative complications has been decreased half, the rate of mesh exposure decreased from 11,3 to 4,7%. Studies on Perigee and Apogee IntePro™ kits, whose meshe and the procedure are similar to the Prolift™ seem to obtain from results equal. The Biological version has not made the object of study. For the Avauta™ kit, alone the mesh in plate not pre-cut has been well studied as for its tolerance for the biosynthetic version. Nothing on the hybrid version. No study is found for the Biomesh® Soft kit and Nazca POP repair system.DiscussionThe cost of these kits, varying 1 to 4, is to take in consideration and to put in scale with the returned service. Alone TVM/Prolift™ allows to advance in a reply. The utilization of needles, presents in all the kits, but especially devices facilitating the passage and the recovery of prosthesis arms, presents solely in the Prolift™ kit, reduce the utilization of valves and the risk of tear tissues during their job. The improvement of techniques by elements of the kit make that the surgical procedure become mini invasive.ConclusionThe full kits allow a best security of procedures, facilitate the surgical gesture and limit complications. It is necessary to remain vigilant in the evaluation of these new materials "ready to wear" and to require pre clinic and clinic studies before their distribution. 相似文献

OBJECTIVES: To assess the effect of the twin-to-twin delivery interval on the umbilical cord blood gas status and the neonatal outcome of the second twin following vaginal delivery. PATIENTS AND METHODS: Retrospective study of twin deliveries at or beyond 34 weeks of gestation over a period of five years. The correlation between the twin-to-twin delivery interval, and the umbilical arterial blood gas parameters of the second twin, including pH, PO(2), PCO(2), HCO(3-) and base excess, was studied. A second analysis was performed after exclusion of non-vertex presentation, need for general anesthesia, growth restriction and weight difference between the twin>30%. RESULTS: Two hundred and thirty-nine patients were studied. The mean twin-to-twin delivery interval was 11.3+/-6.4 minutes (between 6 and 14 minutes in 56.1% of cases). The second twin had more Apgar score<7 at 1 minute (P<0.02) and more arterial ombilical pH<7.20 (P<0.01) than the first twin. Over 15 minutes, the mean arterial pH was lower (P<0.01) and the number of arterial pH<7.20 increased (P<0.03). In contrast, the mean Apgar score and the rate of neonatal transfer did not differ significantly. There were significant negative correlations between arterial pH, base excess and bicarbonates and the twin-to-twin delivery interval (P<0.05). Similar results were found in the homogenised population. The reduction in the second twin arterial pH was expressed as pH=7.282-0.003 x time. DISCUSSION AND CONCLUSION: Umbilical cord arterial blood gas parameters deteriorate with increasing twin-to-twin delivery interval. Our results suggest that this interval should be less than 15 minutes, but obstetrician should adapt to every clinic situation. 相似文献

OBJECTIVE: Primiparity has been identified as the main risk factor of type 3 and 4 perineal injuries The purpose of our study, according to a population-based observational study, was to identify other clinical risk factors for lesions during vaginal delivery. PATIENTS AND METHODS: Two groups have been compared. Group A or study group (n=63) was defined as parturients with three or four-degree perineal tears. Group B or control group (n=67) included women who delivered vaginally without any perineal lesion during the same period. Characteristics of the population were compared: maternal age, race, maternal weight, BMI (Body Mass Index), parity, mode of anaesthesia, gestational age, post maturity, length of labor, fetal weight, mode of delivery (assisted or not). Specific characteristics were also compared, obesity, shoulder dystocia, type of presentation, episiotomy and dose of ocytocin. RESULTS: Primiparity was significantly associated with higher frequency of sphincter lacerations (71 vs 43%, p=0.001). The patients of group A were with significantly higher weight than the patients of control group (67 vs 63 kg, p=0.036). Futhermore the BMI was different in the two groups (25,6 vs 23,4, p=0.003). There was a significant difference according to the length of the second part of labor (68 vs 48 min, p=0.037) and the posterior variety (32 vs 4%, p<0.001). The occurrence of shoulder dystocia was only just significant (6 vs 0%, p=0.052). Assisted-extraction is highly associated with perineal injuries (44 vs 1%, p<0.001). Futhermore the instrument has been concerned by the difference: Tarnier's forceps-assisted extraction (14 vs 1%, p=0.003), Suzor's forceps-assisted extraction (16 vs 0%, p=0.0005), Thierry's spatula-assisted extraction (14 vs 0%, p=0,0005). The association forceps and episiotomy has been found with higher frequency of perineal injury (43 vs 1%, p<0,0001). There were no difference between the 2 groups according fetal characteristics, type of analgesia, maternal age, gestational age, post-maturity or dose of ocytocin. DISCUSSION AND CONCLUSION: Primiparity is not the only risk factor of perineal injuries. Other risk factors have been found: assisted-extraction, occiput posterior fetal head position, and association episiotomy and assisted-extraction. Black origin seems to be protective. 相似文献

OBJECTIVE: To evaluate the deleterious effects of maternal obesity on obstetrical complications and neonatal outcomes. PATIENTS AND METHODS: Historical cohort study including all patients delivered in our maternity between 1st January 2002 and 31st December 2004. Intra uterine death and fetal loss before 22 weeks were excluded. Women were categorized by the Body Mass Index: less than 25, between 25 and 30, and more than 30. Maternal data, obstetrical complications, labor and its complications, and neonatal outcomes were studied. RESULTS: During these 3 years, 23.5% (1336/5686) of patients were overweight and 7.5% (425/5686) were obese. Obstetrical pathologies (gestational diabetes mellitus, hypertension, preeclampsia and fetal macrosomia) and labour induction were more significantly frequent in obese patients (P < 0.01). We noted twice more caesarean sections during labour in obese patients. The rate of artificial placental delivery was significantly higher in obese patients (P < 0.01). Obese patients with prior caesarean sections had a rate of vaginal delivery significantly lower than non obese patients with prior C-sections (23.6 vs 43.8%; P < 0.01). Mean children birth weight was significantly higher in obese patients (3305 vs 3181 g; P < 0.01) with no impact on Apgar score. DISCUSSION AND CONCLUSION: Our study confirms that obesity is responsible for major obstetrical complications, for what should no doubt be considered as high risk pregnancies. Our practices must take these complications into account by ensuring an adapted and early management in order to improve maternal and neonatal issues. 相似文献

The infertility in women with an abnormal uterus seems a subject of controversy. The prognosis of in vitro fertilization among these patients with such an anomaly is even less founded. The results of in vitro fertilization have been only studied with few patients and recently. Through the literature, we will focus step by step, on the impact of uterine anomalies on natural reproduction, then the impact of metroplasty on natural reproduction, the role of anomalies on the endometrium quality and lastly, the results of Assisted Rerpoductive Techniques with women with such an anomaly. It seems that the main risk is obstetric complications such as spontaneous abortion or premature delivery, not implantation failure. However, when infertility exists, surgical treatment tends to improve the pregnancy rate for some. 相似文献

Apoptosis has become a popular biologic concept, for many reasons. From embryonic development to adult tissues, apoptosis is necessary to maintain tissues homeostasis in most organ systems during organogenesis and in the adult. Human spermatogenetic epithelium is also concerned. Dysregulations of this process are involved in many pathologies (leukaemia, auto-immune diseases, etc…), and some forms of male infertility also. Apoptotic features have been found in human semen from infertile patients, and could become useful in order to appreciate semen quality, especially in Assisted Reproductive Technology (ART). Despite numerous studies, some questions remain, especially about meaning of apoptotic damages of spermatozoa. 相似文献
