[Can we reduce the decision-to-delivery interval in case of emergency cesarean sections by optimizing the premises' architecture?] / Peut-on diminuer le délai décision-extraction des césariennes en urgence en optimisant l'architecture des locaux ?

OBJECTIVE: To study the influence of architectural premises' improvements on decision-to-delivery interval (DDI) in case of emergency cesarean sections. METHODS: A retrospective observational Before-After study conducted in a type III maternity, first from 2004 to 2009 (Period 1, P1) then after moving our unit to new premises from 2009 to 2013 (P2). DDI, maternal and neonatal outcomes of every emergency cesarean section were studied. RESULTS: The mean DDI of extremely urgent cesarean significantly decreased from 21.3±10.3minutes during P1 (n=294) to 14.9±7.14minutes during P2 (n=165). During P2 there was an increase in the proportion of extreme emergency cesarean sections done in less than 30minutes (85.1% versus 93.5%, P=0.003) as according to the ACOG recommendations, and also an increase of DDI of less than 15minutes (25.8% versus 61.1%, P<0.001). Also during P2 if there was a reduction of umbilical cord pHs, which were correlated to DDI, we observed a reduction of neonatal hospitalizations (42.2% versus 35.7%, P<0.001). Apgar score was correlated to umbilical cord pH and birth weight, but not to DDI. CONCLUSION: The space optimization has allowed our level III maternity to improve the rate of extreme emergency cesarean sections performed with DDI of less than 30 and even 15minutes, according to international recommendations. These results were obtained by reducing the transfer time to the operating room. Despite a positive correlation between DDI and umbilical cord pH, there was an improvement in neonatal outcomes associated with a decrease of neonatal hospitalizations.

[Comparison of diagnostic performance of two tests of premature rupture of membranes (IGFBP-1/PAMG-1) in clinical practice]. / Comparaison des performances diagnostiques de deux tests de rupture prématurée des membranes (IGFBP-1/PAMG-1) en pratique clinique.

OBJECTIVES: Evaluate the two main immunochromatographic tests of premature rupture of membranes (PROM): Actimprom(®) based on the discovery of insulin-like growth factor binding protein-1 (IGFBP-1) and Amnisure(®) based on the discovery of placental alpha 1-microglobulin (PAMG -1). The comparison was made voluntarily in clinical practice and is interested in a population whose failure is not clean break. MATERIALS AND METHODS: Prospective and comparative study performed on 2012, at the university hospital of Caen, in 85 patients with PROM suspected between 24 SA and 36 SA. The presence of blood, semen or vaginal infection has been notified. Frank rupture of membranes was an exclusion criterion. RESULTS: Actimprom(®) and Amnisure(®) were detected PROM with a specificity, sensitivity, PPV and NPV respectively 89.4% (CI 79.4-95.6%), 68.4% (CI 43.5-87.4%), 65% (CI 40.8-84.6%) and 90.8% (CI 81-96.5%). The results of both tests were not influenced by the presence of blood or inflammatory disease. CONCLUSION: Performance of these tests is probably related to the quality of the sample and the extraction step in bed of the patient. This work showed no significant difference between the two tests in terms of performance in the diagnosis of PROM. At present, there is no formally favor the use of one or the other.

[Peripartum cardiomyopathy: a rare, unknown and potentially fatal disease]. / La cardiomyopathie du péripartum: une entité rare, mal connue et potentiellement mortelle.

Peripartum cardiomyopathy occurs in women with no prior history of cardiac dysfunction, and is presented by left heart failure. It occurs late in pregnancy or in the months after delivery. Rare in Europe, it is not well-known by obstetricians. The prognosis can be good with restitutio in integrum of the maternal cardiac function but the outcome can be dramatic and lead to death of the patient as the case in this report.

[Can we do a cesarean section in less than 30min in unsuitable premises in order to follow the recommendations of the ACOG?]. / Peut-on faire une césarienne en moins de 30min dans des locaux inadaptés afin de suivre les recommandations de l'ACOG ?

OBJECTIVES: This study aims to assess in clinical practice the "decision-to-delivery" interval for an emergency cesarean section depending on the type of care. MATERIALS AND METHODS: This is a retrospective study conducted at the maternity of the CHU of Caen Level III between 2004 and 2009. The comprehensive collection of data totals 294 emergency cesarean sections. The main indications were found to be: bradycardia, cord prolapse, uterine rupture, eclampsia, failure of vacuum extraction on fetal heart rate abnormality during expulsion, the suspicion of placental abruption and hemorrhage in placenta previa. Recorded activities day and night were individualized and the maternal and fetal complications related to the emergency. RESULTS: The mean "decision-to-delivery" interval is of 21.3±10.3minutes with 80.2% of cesarean sections within 30minutes (CE30) and 25.8% in less than 15minutes. Concerning the activity period, the average time at night is 22.5±10.3minutes with 20.7% <15minutes and 77.2% <30minutes and in the daytime, the average time is 20.1±10.1minutes with 31.2% <15minutes and 83.3% <30minutes. The laying of spinal anesthesia in the operating room significantly delays the time of extraction (54.9% vs. 91, 8% CE30, P<0.001), but the epidural before the cesarean section and general anesthesia is faster with 91.9% vs. 78.9% (P=0.002) and 91.8% vs. 81.6% (P=0.022) respectively CE30. We deplored 9 deaths of newborns. These nine deaths represent 3.2% of emergency caesarean sections with an average time of 20.7±14.7minutes. CONCLUSION: The time is influenced by the transition to the operating room, the type of anesthesia and lack of information clearly stated to the team. The fetal prognosis is not limited to the "decision-to-delivery" interval but it remains essential in situations of emergency. The 15 or 30minutes interval is discussed in the literature. Obviously, the delay must be appreciated based on certain parameters (medical personnel, architecture) and each Alpha must adapt their practice to the physical working environment to meet the recommended objectives. However, the introduction of a protocol for extreme emergencies would allow for optimal responsiveness of all the teams involved and should result in a compliance period of 30minutes. Teamwork and adherence to procedures can improve these results.

[Ogilvie's syndrome following cesarean section: Just think! Report of two cases and review of the literature]. / Syndrome d'Ogilvie après césarienne : savoir y penser ! À propos de deux cas post-césarienne et revue de la littérature.

OBJECTIVES: To identify clinical and radiological signs of the post-cesarean Ogilvie's syndrome in order to establish the appropriate treatment. PATIENTS AND METHODS: Based on the Medline research, we listed 41 cases of Ogilvie's syndrome after cesarean section. We analyzed the patient's age, the clinical and radiological signs, the time to diagnosis, and the treatments and their efficiency. RESULTS: The clinical signs generally appear in the first 72 h after cesarean. Diagnosis of Ogilvie's syndrome is based on a clinical picture of acute obstruction of the large bowel and by X-ray showing a large caecum without pathological lesion. If the caecal diameter is under 12 cm, conservative treatment is done with colonoscopic decompression when necessary, however if there are signs of peritonitis surgery is recommended. CONCLUSION: Ogilvie's syndrome after cesarean section is uncommon. Diagnosis must be fast in order to avoid the caecum to burst causing faecal peritonitis, which carries slight mortality rate.

[Fetal pulse oximetry: clinical practice]. / Oxymétrie de pouls foetal en pratique clinique.

OBJECTIVE: To assess in current practice the application of our protocol of using fetal pulse oximetry during labor, to evaluate whether fetal scalp blood sampling can be reduced and to determinate reliability of fetal pulse oximetry on the prediction of poor neonatal outcomes. STUDY DESIGN: Prospective observational unicenter cohort including 449 patients during two years. All pregnancies were singleton, greater than or equal to 37 weeks' gestation, cephalic presentation, and had non reassuring fetal heart rate. The poor neonatal outcome was defined by one of the followings: arterial umbilical cord pH

Rupture of the scarred uterus.

OBJECTIVE: To assess the risk of uterine rupture of the scarred uterus according to mode of delivery in subsequent births recorded as spontaneous labour, labour induced by oxytocin, labour after ripening with prostaglandin E2, and planned cesarean section. METHODS: Retrospective study of 2,128 births with a low transversal scar after a previous cesarean section. The study population was realised in a level III university hospital from 1995 to 2003. The association between mode of delivery and uterine rupture was studied in a multivariate logistic regression model, and adjusted for specific antenatal confounding factors. RESULTS: Over 9 years, we collected 22 cases (1%), including 11 asymptomatic ruptures in a population of 2,128 scarred uteri out of 28,248 deliveries. Uterine rupture occurred at a rate of 0.3 per 100 among women with repeated cesarean delivery without labour, 1 per 100 among women with spontaneous onset of labour, 1.4 per 100 among women with oxytocin-induced labour, and 2.2 per 100 among women with prostaglandin cervical ripening. Compared to women with a planned cesarean section, women with spontaneous onset of labour were more likely to have uterine rupture (OR: 4.0; 95% CI: 0.8-42.0). A greater relative risk was observed among women with oxytocin-induced labour (OR: 4.3; 95% CI: 0.3-60.0), and particularly those with prostaglandin-induced labour (OR: 8.7; 95% CI: 1.5-97.3, p=0.01). CONCLUSION: In women with a scarred uterus, prostaglandin E2 induction of labour is a risk factor for uterine rupture. The practice of a systematic cesarean section in cases with Bishop score<3, appropriate induction procedure, and rigorous monitoring of the labour, could make for a safer delivery.

[Complications of vacuum extractor deliveries]. / Complications des accouchements assistés par ventouse.

OBJECTIVES: To describe maternal and neonatal complications following deliveries assisted by vacuum extraction and to compare outcomes with those obtained after spontaneous vaginal delivery. We wanted to know if vacuum extractor was a risk factor by itself. MATERIALS AND METHODS: We conducted a retrospective study of two years activity involving 4524 deliveries of which 845 (18.7%) were vacuum extractor assisted. We precisely defined maternal and neonatal complications to compare their rates in spontaneous vaginal delivery and vacuum extractor groups. RESULTS: There were 1333 maternal complications and 114 neonatal complications. The adjusted risks of maternal complications were significantly higher in the vacuum extractor group for simple vaginal tears (OR=3.0; p<0.001), the simple perineal tears (OR=1.8; p<0.001) and third degree perineal tears (OR=2.7; p<0.01). For neonatal complications, the difference was significant for cephalhematomas (OR=10; p<0.001) and scalp abrasions (OR=53; p<0.001). No cases of skull fracture or subgaleal subaponeurotic hemorrhage were recorded. CONCLUSION: Our rates of maternal and neonatal complications after vacuum extractor were similar to those described in the literature. We have been able to show that vacuum extraction is itself a risk factor for third degree perineal tears and cephalhematoma. However, these complications are so infrequent that the advantages of this method of extraction argue in favor of wide use in obstetrics.

Congenital rapidly fatal form of nemaline myopathy with fetal hydrops and arthrogryposis. A case report and review.

A new lethal case of nemaline myopathy is reported. The diagnosis was made by postmortem muscle biopsy. The child died before his first day of life. This is one of the very rare cases of nemaline myopathy with severe antenatal ultrasonographic signs: fetal hydrops and arthrogryposis. In a review of the literature other cases of the congenital rapidly fatal form are found, some of them with clinical decrease of fetal movements but only few authors report ultrasonographic signs. The diagnostic, histopathogenic, genetic and evolutive aspects of this heterogeneous disorder are analyzed. This congenital nonprogressive myopathy is not as benign as previously thought and may be an etiology of the lethal form of arthrogryposis multiplex congenita. The existence of ultrasonographic antenatal signs seems to be a factor of poor prognosis. In spite of recent genetic discoveries, there is at present no specific antenatal diagnosis. Consequently, muscle biopsy in lethal cases is very important to allow a genetic counselling; however, in utero fetal biopsy has never been performed in such cases.

Development of the clinical tibiofemoral angle in normal adolescents. A study of 427 normal subjects from 10 to 16 years of age.

We measured the clinical tibiofemoral (TF) angle and the intercondylar (IC) or intermalleolar (IM) distance in 427 normal European children (212 male and 215 female) aged from 10 to 16 years. In our study, girls had a constant valgus (5.5 degrees) and displayed an IM distance of < 8 cm or an IC distance of < 4 cm. By contrast, boys had a varus evolution (4.4 degrees) during the last two years of growth and displayed an IM distance of < 4 cm or an IC distance of < 5 cm. Values above these for genu varum or genu valgum may require careful follow-up and evaluation.

[Spontaneous pregnancies in couples after failed or successful in vitro fertilization]. / Grossesses spontanées chez les couples après échec ou réussite de fécondation in vitro.

OBJECTIVE: To determinate the true incidence of treatment-independent pregnancy in an in vitro fertilization programme. To establish and to compare the characteristics of couples with and without spontaneous pregnancy. To analyze the outcome of pregnancies. TYPE OF STUDY: Retrospective. SETTING: In Vitro Fertilization Unit, Conception's Hospital, Marseille, France. SUBJECTS: 594 couples having attempted one or more IVF procedures. The study concerned low-fertility couples (484) ruling our true sterile couples (110). RESULTS: Spontaneous pregnancies occurred in 54 couples (11.2%). The characteristics of the two populations were not statistically different, except a shorter duration of infertility (p < 0.05) in spontaneous pregnancies. The rate of ectopic pregnancies in the spontaneous pregnancies was statistically higher than that observed in IVP pregnancies (12% versus 6.5%). The fertility rare of these couples was very low (0.38%). CONCLUSION: Spontaneous pregnancies in vitro fertilization programmes are not rare. The evaluation of the results of the in vitro fertilization requires taking the possible spontaneous pregnancies into account.

Contribution to the study of the tributaries and the termination of the external jugular vein.

The dissection of 100 external jugular veins in 50 cadavers was the object of this anatomic study. A certain number of notions concerning the afferent veins, the mode of termination and the valvular system of this vessel were defined. 1) Afferent veins. Along its pathway toward the deep venous system, the external jugular vein successively received: the transverse cervical vein in 88 cases (88%), usually opposite the intersection of the external jugular vein with the dorsal border of the sterno- cleidomastoid muscle; the suprascapular vein in 47 cases (47%); the anterior jugular vein in 46 cases (46%); the cervical vein or anastomosis with the latter in 13 cases (13%). 2) Mode of termination. Forty-three subjects presented a symmetric mechanism. 100 anastomoses can be classed into three types: in 60 cases (60%), the external jugular vein flowed into the jugulo-subclavian venous confluence; in 36 cases (36%), in to the subclavian vein at a distance from its junction with the internal jugular vein; in 4 cases (4%) in to the trunk of the internal jugular vein. 3) Study of the valves. There were studied in 25 subjects (50 external jugular veins). The valves were found in the ostial and paraostial position in 49 out of 50 veins.

[Deformities of the lower limbs in the frontal plane in children]. / Les déformations des membres inférieurs de l'enfant dans le plan frontal.

Idiopathic genu varum and genu valgum are common problems in pediatric orthopedic practice. Standardized evaluation is essential to compare the deformity with age specific normal ranges. Secondary deformities are infrequent, often unilateral, and progressive with growth. Epiphyseal stapling at adolescence is required only in severe deformities. Patient selection for this procedure is difficult because of uncertainties regarding accurate bone age determination and prediction of final poststapling outcome. Closely spaced evaluations between 10 and 13 years of age are helpful for determining the optimal time for stapling.
