[Immediate fetal-maternal morbidity of first instrumental vaginal delivery using Thierry's spatulas. A prospective continuous study of 195 fetal extractions]. / Morbidité maternofoetale immédiate de l'accouchement assisté par spatules de Thierry chez la primipare. A propos d'une série prospective continue de 195 extractions.

OBJECTIVES: To investigate the immediate fetal-maternal morbidity related to Thierry's spatula for first instrumental vaginal delivery. PATIENTS AND METHODS: We conducted a prospective observational study in Toulouse university hospital, including primiparas who vaginally delivered a live singleton cephalic infant>36 WG, between December 2005 and June 2006. Instrumental deliveries were performed using short spatulas in all cases. Outcome measures were: perineal complications (episiotomy, laceration and associated lesions, urinary retention, pain at H48), neonatal morbidity (cutaneous injuries, neonatal transfer, cord pH, Apgar score). Instrumental deliveries were compared with spontaneous vaginal deliveries (SVD). RESULTS: Six hundred and eight primiparas were included, distributed in 195 extractions (32%) and 413 SVD (68%). Spatulas allowed fetal extraction in all cases. Main differences between the two groups were: length of labour, occiput posterior position (12.8% for spatulas vs 1.7% for SVD; p<0.0001), episiotomy rate (97.9% vs 51.3%; p<0.0001), severe perineal lacerations (3.6% vs 0.2%; p=0.0007), post-partum morbidity (pain, hematoma, and urinary retention). No case of early severe neonatal complication was related to the use of the spatulas. DISCUSSION AND CONCLUSIONS: Perineal complications (severe lacerations) associated with spatulas are increased with regard to SVD, but comparable to that reported with forceps. The main disadvantage is the high frequency of episiotomy, which should not be systematic. Neonatal morbidity is reduced. Comparative studies (spatulas vs. other procedures) are needed to confirm these data, but spatulas remain a multipurpose instrument which should continue to be taught.

[Can we still perform instrumental rotations using Thierry's spatula? Preliminary study among primiparous]. / Peut-on encore réaliser des rotations instrumentales par spatules de Thierry? Etude préliminaire chez la primipare.

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.

[Social and demographic characteristics and perinatal risks for highly deprived mothers]. / Caractéristiques socio-démographiques et risques périnatals des mères en situation de précarité.

OBJECTIVE: To assess the frequency of deprivation in pregnant women and estimate the associated medical risks. MATERIAL: and methods. A retrospective study of the hospital's computerised data (6149 women) and two prospective studies with health staff (n=534) and social workers (n=85) in two maternity hospitals. RESULTS: In the retrospective study, 17.5% of mothers were deprived. Deprivation was associated both with more difficulties during pregnancy and the perinatal period and with longer hospital stays. The prospective studies confirmed the prevalence of deprivation and gave a more detailed idea of the associated social and demographic characteristics. Deprivation was related with a combination of risk factors with a particularly important influence of economic risk. A quarter of deprived mothers had unwanted pregnancies and according to the social workers approximately 10% of them were not in a position to take care of their baby. CONCLUSION: This study emphasizes the importance of deprivation as a perinatal medical risk factor. Screening should take place in early pregnancy in order to find the best way to help such families.

Randomized trial of three luteinizing hormone-releasing hormone analogues used for ovarian stimulation in an in vitro fertilization program.

OBJECTIVE: To determine if biochemical differences in luteinizing hormone-releasing hormone analogues (LH-RH-a) have a clinical influence, we studied three of these molecules: buserelin acetate (group B), triptorelin (group T), and leuprorelin (group L). DESIGN: Clinical trial. SETTING: In Vitro Fertilization (IVF) Center. PATIENTS: Two hundred forty-six patients, undergoing their first IVF attempt, were randomly allocated to one group. The analogues were used in a long protocol for ovarian stimulation in an IVF program. RESULTS: After 15 days of LH-RH-a therapy, the follicle-stimulating hormone level was lower in group B (2.9 +/- 1, 4.3 +/- 1.7, 4.8 +/- 2.1 UI/L for B, T, and L groups, respectively; P less than 0.001), although no difference was found in LH and estradiol (E2) levels. After follicular growth stimulation by human menopausal gonadotropins (hMG), E2 level was significantly lower in B group (1,799 +/- 1,101, 2,440 +/- 1,298, 2,137 +/- 1,044 pg/mL for B, T, and L groups, respectively; P less than 0.01), as well as the E2 level per hMG ampule (67 +/- 51, 97 +/- 61, 82 +/- 49 for B, T, and L groups respectively; P less than 0.01). The pregnancy per stimulated cycle rate was not significantly different among the groups. CONCLUSIONS: These results suggest that LH-RH-a could act not only on the pituitary but also on the ovaries. Moreover, these data suggest that buserelin acetate could be preferentially used for high responders and triptorelin for poor responders.

Influence of ovarian cysts on the results of in vitro fertilization.

OBJECTIVE: To determine if ovarian cysts are associated with a particular basal endocrine profile and impair follicular growth. DESIGN: Retrospective study. SETTING: In Vitro Fertilization (IVF) Center. PATIENTS: Nine hundred fourteen stimulation cycles stimulated with a combination of luteinizing hormone-releasing hormone analogues (LH-RH-a) and human menopausal gonadotropins (hMG) in a long protocol in an IVF program. RESULTS: After 15 days of LH-RH-a therapy, ovarian cysts (> or = 20 mm) were observed in 8% of cases. These cysts were not related to a particular basal endocrine profile and did not impair follicular growth and IVF results. However, puncturing these cysts enhanced the quality of subsequent follicular growth. On the contrary, cysts appearing during hMG treatment (> or = 25 mm) were related with a lower LH:follicle-stimulating hormone ratio (0.79 +/- 0.52 versus 0.92 +/- 0.74 in absence of cyst) and to a lower ovarian response as assessed by the maximal estradiol level to the total number of hMG ampules ratio (51.6 +/- 36.5 versus 65.9 +/- 47.9 in absence of cyst). However, this difference had no influence on the pregnancy per stimulation rate (18% versus 16% in absence of cyst; not significant). CONCLUSIONS: Results show that the pathogens of ovarian cysts appearing during the blockage phase and during the stimulation phase are different. However, they do not impair the results of IVF, and thus it is not necessary to cancel the attempt in case of ovarian cyst.

Randomized trial of two media used for in vitro fertilization.

Culture media are important components of IVF. Their selection must meet the need for efficiency, and also economic and practical requirements. From these standpoints, we compared two widely used media: Ham's F10 supplemented with cord serum and Menezo B2 used without serum. The test followed a randomized protocol using two series of 159 and 162 oocytes. Since no difference was seen in efficiency assessed from cleavage rate, the discussion focuses on cost and ease of use.

Assessment of the predictive value of X-ray pelvimetry and biparietal diameter in cephalopelvic disproportion.

The value of X-ray pelvimetry and ultrasonic measurement of the biparietal diameter for trial of labor prognosis was assessed in 172 healthy primiparas with suspected cephalopelvic disproportion. A decision diagram which is able to correctly predict 50% of the cesarean sections without increasing the number of unnecessary cesarean sections is proposed. In addition, the study confirms the superfluity of X-ray pelvimetry in cases of high station of the fetal head at the end of pregnancy.

Respective consequences of abdominal, vaginal, and laparoscopic hysterectomies on women's sexuality.

OBJECTIVE: To determine the relative effects of abdominal, vaginal or laparoscopic approaches for hysterectomy on female sexuality. STUDY DESIGN: One hundred and seventy women who underwent abdominal (n=68), vaginal (n=67), and laparoscopic (n=35) hysterectomy for benign disease were studied. Pre- and postoperative sexuality was assessed by questionnaire. RESULTS: Overall, sexuality after hysterectomy remained unchanged in 60.4% of cases, and improved or deteriorated in 21.3 and 18.3%, respectively. Postoperative delay in resuming sexual activity was shorter after vaginal (45.2+/-6.7 days) hysterectomy than after abdominal hysterectomy (62.4+/-9.3 days). Deterioration of sexual function occurred more frequently after abdominal hysterectomy (24%) than after vaginal (13.5%) or laparoscopic (8.5%) hysterectomy. CONCLUSION: These results indicate that the impact of vaginal and laparoscopic hysterectomy on women's sexuality may be milder than that of abdominal hysterectomy.

Choice of an ovarian stimulation protocol according to the follicular puncture method in an in vitro fertilization programme.

In order to ascertain the adequacy of ovarian stimulation protocols with a type of follicular puncture, 126 women undergoing in vitro fertilization received either combination clomiphene/hMG or hMG alone according to a randomized test protocol. Within both groups patients for whom a pelvic examination was required had laparoscopies, while others had transvaginal ultrasonically guided punctures as far as possible. Clomiphene/hMG was more efficient than hMG alone as assessed from the cleavage rate (68% vs. 54%; p less than 0.01) and the pregnancy per attempt rate (16% vs. 5%; p less than 0.05). Laparoscopic punctures were more efficient than ultrasonically guided punctures (mean number of recovered oocytes: 4.8 +/- 2.6 vs. 3 +/- 2.5; p less than 0.001), but slightly better results were achieved by this latter method in ongoing pregnancy per puncture rate (18% vs. 8%; NS). With ultrasonically guided punctures, stimulation by clomiphene/hMG allowed better oocyte recoveries (3.8 +/- 2.5 vs. 2.3 +/- 1.9, p less than 0.05). Such results constitute an argument for preferential use of the clomiphene/hMG stimulation protocol with ultrasonically guided punctures.

Paradoxical ovarian stimulations in the use of LHRH analogs.

In the case of in vitro fertilization, LHRH analogs are used to induce an hypophysary blockage, before the phase of stimulation, via administration of exogenous gonadotropin. During in vitro fertilization attempts using LHRH analogs, the blockage is controlled after 14 days of treatment through measurement of the plasmatic estradiol and pelvic ultra-sonography. In this retrospective study, which concerned 1075 in vitro fertilization cycles, a paradoxical ovarian stimulation with LHRH analogs was observed in 93 cases (8.7%), with high estradiol levels and follicular growth (detected by ultra-sonography), in spite of low FSH and LH levels. In 4 cases, a follicular puncture was performed, which allowed to collect oocytes from which embryos were obtained, thus confirming the observed follicular growth and maturation. The most probable hypothesis explaining this phenomenon seems to be a direct ovarian stimulation, effectuated in vivo by LHRH analogs. This stimulation is only observed in certain patients, and apparently more frequently, with certain LHRH analogs, probably through a variation in the expression of ovarian LHRH receptors.

[Vaginal hysterectomy in fibroma. Apropos of 453 cases. Retrospective comparison with 509 cases of abdominal hysterectomy]. / Hystérectomie vaginale pour fibrome. A propos de 453 cas. Comparaison rétrospective à 509 hystérectomies abdominales.

The authors present a series of 962 hysterectomies for fibroma carried out between January 1981 and December 1995 in the Department of Gynecology and Obstetrics of CHU Toulouse-La Grave. They carried out 453 vaginal hysterectomies and 509 abdominal hysterectomies. They compared the largest series reported in the literature, between vaginal and abdominal technique. The vaginal route has the obvious advantages of speed of operation, less operative trauma, lower risk of thrombo-embolic disease and the hospital stay is shorter. Laparoscopic assistance allows to extend indications of vaginal route.

[From failure to success? A case of reduction of the number of embryos in a septuplet pregnancy]. / De l'échec au succès? Un cas de réduction embryonnaire d'une grossesse septuple.

The authors report a case of septuplet pregnancy that occurred after stimulation of ovulation using h.M.G.-h.C.G. This multiple pregnancy occurred because of failure of the triple surveillance using clinical, biological and ultrasound techniques. The number of embryos was reduced by needling through the abdominal wall. Two procedures were necessary. The technique that was used is described in detail and illustrated. The twin pregnancy that was left carried on successfully. This describes a technique that should be used rarely and should not in any way modify the strict rules for monitoring ovulation.

[A review of six years use of a computerised case history in obstetrics (author's transl)]. / Bilan de six ans d'exploitation d'un dossier informatisé en obstétrique.

The University Centre for Gynaecology and Obstetrics in Toulouse have been using a computerised record system for obstetrics since 1974. This makes it possible for a review for a review to be undertaken each year of the work carried out in the Service and has made it possible to study over six years the evolution of the characteristics of the population who have been followed, as well as the changes in attitudes and techniques adopted during pregnancy and labour. A study has been carried out on the factors associated with perinatal mortality and prematurity. Computerisation of 13,500 records has made it possible to draw curves of birth weights, according to the duration of the pregnancy, and characterising the service given. Finally the adoption of a prospective record system used in common by several teams and checked by people specialised in this work has improved the quality and quantity of retrieval and has made it possible to foresee cooperative studies between different departments.

[Parametrial pregnancy. Report of a case of "paracervical" pregnancy treated by medico-surgical management]. / Grossesse paramétriale. A propos d'un cas de grossesse "paracervicale" traitée par association médico-chirurgicale.

We report an exceptional case of para-cervical pregnancy. Ultrasonography enabled accurate diagnosis after explorative laparoscopy. Treatment was conservative involving methotrexate and surgical ablation of the pregnancy by vaginal approach with a successful outcome.

[Pregnancy and labor of women born in Maghreb and Black Africa followed to delivery at the Maternity Hospital of Toulouse]. / Grossesse et accouchement de femmes originaires du Maghreb et d'Afrique noire suivies à la maternité du CHU de Toulouse.

OBJECTIVE: To identify risk factors related to maternal ethnic origin. METHODS: Retrospective review of 5808 cases of French, Maghrebian and Black African women who delivered between 1988 and 1994 at the Maternity of La Grave Hospital in Toulouse. RESULTS: Pathological pregnancies were more frequent (60% vs 45%), specifically anemia OR = 10.2[6.3-16.7] and OR = 5.7[4.0-8.3]) and genital infections (OR = 1.7[1.2-2.6] and OR = 1.7[1.4-2.1]) in African and Maghrebian respectively. than in French women. These differences cannot be referred to any classical risk factors but only to the mother's ethnic origin. Moreover, cesarean delivery occurred almost twice as much in African women 34% vs 19%) and no specific medical indication was found to explain this increase. CONCLUSION: Our data concluded that important risk factors were related to the mother's ethnic origin. This finding demonstrates that management of perinatal care and epidemiologic studies should take maternal ethnic origin into account.

[Cesarean section trends at the Toulouse University Hospital, from 1983 to 1993. Determinants and consequences]. / Evolution des taux de césarienne au CHU de Toulouse, de 1983 à 1993. Déterminants et conséquences.

OBJECTIVE: To examine the factors accounting for the increase in rate of cesarean section, between 1983 and 1993 (from 13.0% to 19.5%) in Toulouse University Hospital, a tertiary level center. DESIGN: Retrospective study of all single deliveries, excluding deaths in utero, between 1983 and 1993. RESULTS: Half the increase in overall rate was due to the numerical increase in women with a cesarean section history. The percentage of cesarean sections in these patients remained constant at 79% over this period. For the other patients, the increase in rate was due partly to an increase in risk factors, but mainly to a change in obstetric practice with a marked increase in elective cesarean section (70% of all cesarean sections in 1993). Major complications in the mothers were relatively rare, albeit significantly more frequent in the cesarean cases. Over the study period the percentage of infants requiring intensive care remained constant for the vaginal deliveries but declined for the cesarean sections. CONCLUSION: The increased rate of cesarean sections has not led to any increase in maternal complications, and appears to have had a small favorable influence on infant morbidity.

[Neuroleptic analgesia in the management of labor]. / La neuroleptanalgésie dans la direction majeure du travail.

Neuroleptic analgesia, which is used for the major part of the conduct of labour, has the advantage of abolishing the pain of uterine contractions without altering the mother's state of consciousness. A study of the effects of droperidol together with phenoperidine on the mother and the child has been carried out. Clinical results, the parameters of the intra-uterine pressure curves and the fetal heart rates as well as of the acid base balance and the pO2 of the mother and infant during dilatation of the cervix and the two first hours of life have been monitored. The conclusion is that neuroleptic analgesia does not cause neonatal depression and can be used as a method for conducting labour so long as very strict monitoring conditions are applied.

[The value of measuring blood pH in fetal monitoring during labour (author's transl)]. / Intérêt de la mesure du pH sanguin dans la surveillance foetale pendant l'accouchement.

The authors present a series of methodological studies carried out to assess the value of the place of measuring fetal blood pH in monitoring in labour. Comparisons of the measures of pH, pCO2, pO2 and lowering of the base were carried out on the scalp in the 3 minutes which preceded the birth and in the umbilical vessels at birth. Comparing the three modes of taking blood in the mother, intra-arterially and from the capillaries with and without local vasodilatation was carried out. The limits of the values were defined both for the fetus and the mother of the parameters of pH, pCO2, pO2 and base deficit in 100 normal deliveries. A study was carried out of their correlations with the Apgar score at 1 minute and with the arterial pH. A comparison of the two series of measurements was carried out on the vessels of the cord--arterial and venous. The results confirm the value of measuring pH for diagnosing the state of the infant during labour.

[Ripening of the cervix uteri at term by a single intracervical application of prostaglandin E2 gel]. / Maturation du col utérin à terme par application unique d'un gel de prostaglandine E2 intracervical.

The efficacy and the side effects of an intracervical PGE2 gel application, as compared to placebo, for priming of the cervix have been studied in 208 patients at term (104 PGE2 and 104 placebo) with an unripe cervix (Bishop score less than 5) and with a medical indication for induction of labour. The cervical ripening success rate (as defined in methodology) is significantly higher in the treated group (58.6%) than in the control group (27.8%; p = 0.0001): 38.5% out of the PGE2 treated patients delivered within 12 hours after the gel application; 12 hours after PGE2 or placebo gel application labour was induced in the remaining patients with intravenous oxytocin infusion. Under these conditions there were 13.5% failures in the PGE2 treated group and 16.3% in the placebo group. We observed a statistically significant decrease in the length of labour of the PGE2 treated patients as compared to the control group. Since signs of myometrial hypercontractility were observed in the PGE2 treated group as compared to the control group (p = 0.01), the authors advocate careful cardiotocographic monitoring for at least three hours after the gel application. It is concluded that intracervical application of Prostaglandin E2 followed by intravenous infusion of oxytocin in an effective and safe method for induction of labour with an unfavorable cervix at term.
