[Anal sphincter tears after vaginal delivery: risks factors and means of prevention]. / Lesions sphinctériennes anales après accouchement par voie vaginale: facteurs de risque et moyens de prévention.

To identify incidence and risks factors of obstetrical anal sphincter lacerations, we reviewed all cases of 3rd and 4th degree sphincter lacerations after vaginal deliveries (VD) occured in a tertiary maternity between 2005 and 2010. 78 anal sphincter lacerations were identified (3.8/1000 deliveries). 66 women (85%) were nulliparous. The mean age of women was of 29 +/- 5 years. The mean duration of the second stage of labour was of 3.4 +/- 1,7 hour. The birth weight of 12 newborns (15%) was greater than 4000 grams. Fourty-six women (2.5%) had sphincter lacerations after instrumental delivery and 32 after spontaneous vaginal delivery (0.2%). 51 patients out of 78 (65%) had a medio-lateral episiotomy, 82% occured after instrumental extraction and 43% after spontaneous delivery. A forceps of Tarnier was used in 18 cases, a Suzor forceps in 12 cases, spatula in 12 cases and vacuum in 4 cases. 76% of foetuses were in anterior presentation and 78% at the medium part of the pelvis. 2 patients experienced anal incontinence in early post-partum. Anal sphincter lacerations are relatively frequent after VD especially after instrumental delivery. Macrosomia, nulliparous women, prolonged second stage of labor were associated with anal sphincter tears. Medio-lateral episiotomy does not protect enough anal sphincters. Anal sphincter lacerations lead to anal incontinence in some cases.A long follow-up is useful for these patients.

[Management of umbilical cord prolapse and neonatal outcomes]. / Procidence du cordon: prise en charge obstétricale et conséquences néonatales.

OBJECTIVE: To evaluate the obstetrical management of umbilical cord prolapse and the neonatal outcomes. METHODS: Retrospective study of 57 prolapses of umbilical cord between 1998 and 2009. Arterial pH of umbilical cord, Apgar score and diagnosis delivery time (DDT) were analyzed. RESULTS: The incidence of the cord prolapse was of 1.25 for 1000 deliveries. Cord prolapse occurred with the artificial rupture of membranes in 24 cases (42%) out of 57. There were 48 caesarean births. There were three hydramnios and seven cases of twin pregnancy. The mean pH in the umbilical arteries was 7.15 ± 0.13 in 27 cases. The mean Apgar for the 57 newborns was 6 ± 3 at 1 min and 8 ± 3 at 5 min. The mean DDT was 18 ± 8 min (range: 3-44). In 17 cases out of 27, the mean arterial umbilical pH was 7.07 ± 0.09. Fifteen newborns (26%) had a 5-minute Apgar score less than 7 and were admitted in intensive care unit. The mean Apgar score in the nine vaginal deliveries was 8 ± 4 min. In case of cephalic presentations without associated foetal or maternal pathologies there was a tendency of a better pH when the DDT was shorter. In non-cephalic presentations (14 cases), the mean Apgar score was 8 ± 3 at 5 min. The mean pH measured in eight cases was 7.20 ± 0.13 with mean DDT of 20 minutes. CONCLUSION: The umbilical cord prolapse remains a serious event for the newborns. The reduction of the DDT in cephalic presentation seems to be correlated to a better neonatal state. The caesarean section is the preferential way of childbirth.

[Congenital toxoplasmosis: a new case of infection during pregnancy in an previously immunized and immunocompetent woman]. / Toxoplasmose congénitale: un nouveau cas d'infection pendant la grossesse chez une femme antérieurement immunisée et immunocompétente.

UNLABELLED: Congenital toxoplasmosis is a potentially serious infection which usually affects infants born to non immune women. CASE REPORT: Our case report focuses on a baby born to a normally immunocompetent woman previously immunized against toxoplasmosis. To our knowledge only three similar cases have been published until now. CONCLUSION: We conclude that in front of a patient neonatal congenital infection picture, toxoplasmosis cannot be excluded on the ground of maternal immunity status and must be quickly investigated, given the emergency of appropriate treatment.

[Color and pulsed Doppler ultrasonography imaging of tubal ectopic pregnancy: study of 100 cases]. / Les aspects en Doppler couleur et pulsé de la grossesse extra-utérine tubaire: expérience à propos de 100 cas.

OBJECTIVE: To describe the color-Doppler findings and the spectral forms of pulsed Doppler in tubal ectopic pregnancies. MATERIALS AND METHODS: A prospective study of one hundred patients with tubal ectopic pregnancies was carried out in the emergency ward by two operators from January 1993 to March 1999. Following transabdominal and/or endovaginal sonography of the pelvis, color Doppler of the adnexa and of any suspected latero-uterine abnormal vascularity were studied with pulsed Doppler. The diastolic index (D/S) was measured on 4 consecutive complexes. RESULTS: Sixty-six peripheral hypervascularizations, 27 irregular hypervascularizations and 7 false negatives were found with color Doppler. The pulsed Doppler spectrum revealed a low-impedance flow in 47 cases (D/S index > or = 0.35) and a high-impedance flow in 46 cases (D/S index < 0.35). The latter spectrum was found in 7 cases of tubal rupture with massive hemorrhage and 39 cases of barely evolutive ectopic pregnancies. CONCLUSION: Color Doppler facilitated the diagnosis of small ectopic pregnancies (gestational sac less than 1 cm and echogenic lesions less than 2 cm in maximum diameter). Our work with pulsed Doppler revealed the frequence of high-impedance flow which, in the absence of massive hemoperitoneum, strongly suggests a barely evolutive ectopic pregnancy.

[Ultrasonography of placenta previa at the third trimester of pregnancy: research for signs of placenta accreta/percreta and vasa previa. Prospective color and pulsed Doppler ultrasonography study of 45 cases]. / Placentas bas insérés échographiquement au 3e trimestre de la grossesse: recherche de signes de placenta accreta/percreta et de vaisseaux praevia. Etude prospective en échographie Doppler couleur et pulsé de 45 cas.

OBJECTIVES: In a population of 45 placenta previa observed at third trimester of gestation we have tried to make the prenatal diagnosis of placenta percreta and vasa previa with color and pulsed Doppler ultrasonography. MATERIALS AND METHODS: We used a transabdominal sonography with full bladder and a transvaginal sonography with empty bladder. The first images obtained showed 20 placenta previa over the internal cervical os, 3 marginal and 22 low-lying placenta previa. We tried to find evidence of placenta percreta with gray-scale ultrasonography (loss of normal hypoechoic retroplacental myometrial zone, focal disruption of the uterine serosa and surrounding tissues, presence of intra placental lacunae) and with color and pulsed Doppler (arterial vessels with a diastolic flow value less than the flow value of a spiral artery behind the placenta, arterial vessels crossing from the placenta to surrounding tissues, intraplacental lacunae with arterial flow). We tried to find evidence of vasa previa in color and pulsed Doppler (a fetal vessel in seen above the lower segment of the uterus and below the fetal head. There is no change in the location of the vessel despite positional changes in both mother and fetus). The positivity of one sign in gray-scale ultrasonography or in color and pulsed Doppler led us to believe that the patient was affected by the anomaly. The final diagnosis of abnormal adherence of the placenta and of vasa previa was made on histological examination. RESULTS: Among the 20 placenta previa over the internal cervical os, we found 1 placenta percreta, 1 placenta accreta and 3 cases of vasa previa. In spite of our limited sample of cases of abnormal adherences, our results showed that gray-scale ultrasonography was sufficient to make a prenatal diagnosis of placenta accreta/percreta. Negative predictive value is 100% on a sample of 43 patients with no abnormal placental adherence. Color and pulsed Doppler brought no further evidence. In our population, color and pulsed Doppler had 100% positive predictive value for diagnosis of vasa previa. CONCLUSION: We found the only 2 cases of abnormal adherent placental fragments and the 3 cases of vasa previa present in our population. The study of the lower segment of the uterus should be thorough as abnormal zones may be small-sized. Color Doppler is the reference technique for sighting vasa previa and gray-scale ultrasonography for abnormal adherences of the placenta.

Prenatal ultrasonographic diagnosis of the cerebro-costo-mandibular syndrome: case report and review of the literature.

We present an antenatal ultrasonographic diagnosis of the cerebro-costo-mandibular syndrome. This rare dysmorphic disorder (only 51 cases have been reported to date) mainly associates defective costal development with features of the Pierre-Robin syndrome. The diagnosis is very often made at birth and the prognosis is very poor. Antenatal ultrasound examination may show a combination of orofacial and chest maldevelopment. In our case the diagnosis was made at 20 weeks' gestation during a routine ultrasound examination and the patient chose to terminate the pregnancy at 24 weeks.

[Prenatal diagnosis of vasa previa with velamentous cord insertion, using Doppler color echography]. / Diagnostic anténatal de vaisseaux praevia, avec insertion vélamenteuse du cordon, grâce à l'échographie-Doppler couleur.

We report a case of prenatal diagnosis of vasa previa, using colour Doppler imaging. This affection is rare, but can be responsible for very severe fetal complications during the delivery. Elements of the diagnosis were demonstrated in the clinical case and discussed. This is a new use of transvaginal colour Doppler in Obstetrics.

[Prenatal diagnosis of a placenta praevia percreta with color Doppler. A case report. Review of the literature]. / Diagnostic anténatal d'un placenta praevia percreta grâce au Doppler couleur. A propos d'un cas. Revue de la littérature.

Placenta praevia percreta, with bladder invasion, was diagnosed at 29 weeks of amenorrhoea with colour Doppler which visualized vascular bundles leaving the placenta and reaching the lower part of the bladder. These bundles were identified as including arterial elements with pulsed Doppler. The criteria for the diagnosis of placenta accreta with ultrasonography and colour Doppler have been presented in the literature. This prenatal diagnosis allowed adapted preoperative management and intensive care, however air embolism could not be avoided and the patient died at the end of the operation.

[Urinary tract infection in gynecology-obstetrics: resistance to beta-lactam antibiotics and previous antibiotic therapy]. / Infection urinaire en gynécologie-obstétrique: résistance aux bêtalactamines et antibiothérapie préalable.

From June 1988 to October 1989, 190 women from the department of Obstetrics-Gynecology with bacteriuria due to Gram-negative rods were studied. One hundred and three were investigated as ambulatory patients. Fifty three had received treatment with a bêta-lactam antibiotic during the past three months and 11 between three and six-months before sampling. The organisms causing bacteriuria were 163 E. coli, 12 P. mirabilis and 15 were due to other species. Thirty three E. coli and the 15 other species were resistant to amoxicillin and/or to cefalotin. When comparing previous treatment and resistance to amino-penicillins it appears that: of the women who had received a beta-lactam antibiotic within the three months before testing, 57% of the strains recovered were found resistant for amino-penicillins; of the women without treatment during the past six months, 89% of the strains recovered were sensitive and six per cent of E. coli plus five per cent of another Gram negative rod were resistant to amino-penicillins.
