Comparative study of muscle-sparing latissimus dorsi vs breast implants following total mastectomy.

INTRODUCTION: With 60,000 cases per year, breast cancer is the most frequent type of cancer in France, and a quarter of these cases require mastectomy. Following the surgery, breast reconstruction can be indicated. Two of the available techniques are breast implants (BIs) and muscle-sparing latissimus dorsi (MSLD). The aim of this study was to compare postoperative complications of each approach and thus help the surgeon and the patient in making an informed decision before surgery. MATERIALS AND METHODS: This descriptive, retrospective and single-centre study was conducted in the Croix Rousse hospital in Lyon (France) between 1 July 2018 and 1 July 2023. It included women aged ≥18 years who underwent mastectomy followed by (immediate or delayed) breast reconstruction with MSLD or BI. Complications were recorded and evaluated using the Clavien-Dindo classification. RESULTS: Over the course of the study, 92 patients were managed with MSLD reconstruction and 63 patients with BI. We observed a complication rate of 62% in the BI group and 39% in the MSLD group (odds ratio [OR]=0.16; p < 0.005). Body mass index (BMI) significantly impacted this rate (OR=1.11; p = 0.01), whereas smoking status and diabetes did not. No complication occurred more predominantly than others. A second surgery was required more often in the BI group (p < 0.005). There were no severe complications (>Grade 4). CONCLUSION: MSLD predicted fewer complications and was associated with a shorter hospital stay compared with implants, suggesting that it may be a preferable option for breast reconstruction.

Management of women with abnormal uterine bleeding: Clinical practice guidelines of the French National College of Gynaecologists and Obstetricians (CNGOF).

OBJECTIVE: To provide French guidelines for the management of women with abnormal uterine bleeding (AUB). DESIGN: A consensus committee of 26 experts was formed. A formal conflict-of-interest policy was developed at the beginning of the process and enforced throughout. The entire guidelines process was conducted independently of any industry funding (i.e. pharmaceutical or medical device companies). The authors were advised to follow the rules of the Grading of Recommendations Assessment, Development and Evaluation (GRADE®) system to guide assessment of quality of evidence. The potential drawbacks of making strong recommendations in the presence of low-quality evidence were emphasized. METHODS: The last guidelines from the Collège National des Gynécologues et Obstétriciens Français on the management of women with AUB were published in 2008. The literature seems now sufficient for an update. The committee studied questions within 7 fields (diagnosis; adolescents; idiopathic AUB; endometrial hyperplasia and polyps; type 0-2 fibroids; type 3 or higher fibroids; and adenomyosis). Each question was formulated in a PICO (Patients, Intervention, Comparison, Outcome) format and evidence profiles were compiled. The GRADE® methodology was applied to the literature review and the formulation of recommendations. RESULTS: The experts' synthesis work and the application of the GRADE method resulted in 36 recommendations. Among the formalized recommendations, 19 are strong and 17 weak. No response was found in the literature for 14 questions. We chose to abstain from recommendations rather than providing advice based solely on expert clinical experience. CONCLUSIONS: The 36 recommendations make it possible to specify the diagnostic and therapeutic strategies for various clinical situations practitioners encounter, from the simplest to the most complex.

Surgical management of a loss of pregnancy in the first trimester: Patient experience and influencing factors, a prospective observational study.

OBJECTIVE: Describe the "patient experience" regarding care provided during the surgical management of a loss of pregnancy in the first trimester and identify the factors influencing this experience. MATERIAL AND METHODS: It is an observational prospective study conducted in two type III, academic, maternity wards in Lyon, France, carrying out 8,500 deliveries per year. Adult female patients, having undergone a suction curettage for a loss of pregnancy in the first trimester from 24 December 2020 to 13 June 2021 were inculded. The "patient experience" was assessed using the 15 questions of the Picker Patient Experience (PPE-15) questionnaire, and research was conducted on factors influencing the patient experience. The main outcome was the percentage of patients reporting a problem in response to at least one of the PPE-15 questions. RESULTS: 58 out of 79 patients (73% CI [62-83]) reported at least one problem with their care. The largest proportion of problems was raised in question about "Opportunity for family/loved ones to talk to the doctor" (76% CI [61-87]). The lowest proportion of problems was raised in question about "Treated with respect and dignity" (8% CI [3-16]). No factors influencing the patient experience were identified. DISCUSSION: Almost three out of four patients reported a problem in the experience as a patient. The main areas of improvement reported by patients were the participation of their family/relatives and the emotional support provided by the healthcare team. TWEETABLE ABSTRACT: Better communication with patient families and emotional support could improve patient experience during the surgical management of a loss of pregnancy in the first trimester.

[How is our practice of mastectomy? Analysis based on population data in a French department]. / Quelles évolutions dans notre pratique de la mastectomie ? Analyse à partir de données de population dans un département français.

OBJECTIVE: The objective of this research was to study the evolution of the mastectomy rate in patients with breast cancer between 1998 and 2015, based on population data from the Côte d'Or breast cancer registry of the FRANCIM network ("France cancer incidence and mortality"). METHODS: In this study on population register we included patients who had presented a primary breast cancer (invasive cancer and/or carcinoma in situ [CIS]) between 1998 and 2015 in the Côte d'Or department. We estimated the annual proportions of mastectomies, then calculated their evolution trends over this period. RESULTS: Between 1998 and 2015, 7093 patients were included. The overall proportion of mastectomies was stable at 28% and did not respond to a time trend (Sen's slope of 0.2% per year; P=0.289). There was an increase in the proportion of lobular carcinomas (slope at 0.3% per year; P <0.05), with a rising proportion of mastectomy for lobular carcinomas (slope at 0.6% per year; P<0.05) but decreasing for ductal (slope at -0.8% per year; P<0.05). The proportion of mastectomy was stable for plurifocal cancers but the proportion of plurifocal cancers increased over time (slope at 0.8% per year; P<0.05). CONCLUSION: Therefore, mastectomy remained a stable practice over the 18 years of analysis in the Côte d'Or region. However, this overall stability is the result of variations in the profiles of diagnosed cancers and surgical practices.

[Management of women with abnormal uterine bleeding: Clinical practice guidelines of the French National College of Gynecologists and Obstetricians (CNGOF)]. / Prise en charge des ménorragies : recommandations pour la pratique clinique du Collège national des gynécologues et obstétriciens français (CNGOF).

OBJECTIVE: To provide French guidelines for the management of women with abnormal uterine bleeding (AUB). DESIGN: A consensus committee of 26 experts was formed. A formal conflict-of-interest (COI) policy was developed at the beginning of the process and enforced throughout. The entire guidelines process was conducted independently of any industrial funding (i.e. pharmaceutical, or medical devices). The authors were advised to follow the rules of the Grading of Recommendations Assessment, Development and Evaluation (GRADE®) system to guide assessment of quality of evidence. The potential drawbacks of making strong recommendations in the presence of low-quality evidence were emphasized. METHODS: The last guidelines from the Collège national des gynécologues et obstétriciens français (CNGOF) on the management of women with AUB was published in 2008. The literature seems now sufficient for an update. The committee studied questions within 7 fields (diagnosis; adolescent; idiopathic AUB; endometrial hyperplasia and polyps; fibroids type 0 to 2; fibroids type 3 and more; adenomyosis). Each question was formulated in a PICO (Patients, Intervention, Comparison, Outcome) format and the evidence profiles were produced. The literature review and recommendations were made according to the GRADE® methodology. RESULTS: The experts' synthesis work and the application of the GRADE method resulted in 36 recommendations. Among the formalized recommendations, 19 present a strong agreement and 17 a weak agreement. Fourteen questions did not find any response in the literature. We preferred to abstain from recommending instead of providing expert advice. CONCLUSIONS: The 36 recommendations made it possible to specify the diagnostic and therapeutic strategies of various clinical situations managed by the practitioner, from the simplest to the most complex.

The psychological impact of therapeutic changes during the COVID-19-lockdown for gynaecological and breast cancer patients.

OBJECTIVE: The exceptional health situation related to the Coronavirus 2019 (COVID-19) pandemic has required an in-depth and immediate reorganisation of gynaecological cancer care. The main objective was to assess the psychological impact of such treatment modifications during the lockdown period for gynaecological and breast cancer patients. PATIENTS AND METHODS: A multicentre prospective study was conducted in three university gynaecological cancer wards (Hospices Civils de Lyon, France) during the French first lockdown (16th March to 11th May 2020). All patients with non-metastatic breast cancer or gynaecological cancer were included. Data was collected regarding treatment modifications (delay, cancellation, change of therapeutic plan). The psychological impact of treatment modifications during and after the lockdown was assessed by validated questionnaires (SF-12, EORTC-QLQ-C30, HADS). RESULTS: A total of 205 consecutive patients were included, aged 60.5 ± 1.0 years. Seven patients (3.4%) presented a SARS-CoV-2 infection, and two patients died. Treatment was maintained for 122 (59.5%) patients, postponed for 72 (35.1%) and cancelled for 11 (5.4%). During the lockdown, 35/118 (29.7%) patients suffered from confirmed anxiety and the mean fatigue-EORTC score was 48.00 ± 2.51; it was 38.64 ± 2.33 (p = 0.02) after the lockdown. After the lockdown and compared to the lockdown period, the mental SF-12 score and overall health status EORTC score were significantly higher (45.03 ± 1.06 vs 41.71 ± 1.15, p = 0.02 and 64.58 ± 1.66 vs 57.44 ± 2.02, p = 0.0007, respectively). The number of confirmed-anxiety cases was significantly higher amongst patients for whom treatment was delayed or cancelled (40.5% vs 23.7%, p = 0.04). CONCLUSION: This study quantified the treatment modifications of gynaecological cancer patients during the COVID-19 lockdown and revealed a poorer psychological state and quality of life during this period, even for patients whose treatment plan was not actually modified. Anxiety was more significant in patients with a delayed or cancelled treatment.

[Surgery or not on an atypical breast lesion? Taking anxiety into account in shared decision support from a prospective cohort of 300 patients]. / Opérer ou non une lésion atypique du sein ? Prise en compte de l'anxiété dans l'aide à la décision partagée à partir d'une cohorte prospective de 300 patientes.

INTRODUCTION: Organized and individual breast screening have been accompanied by an increase in the detection of "atypical breast lesions (ABL)". Recently, the NOMAT multicenter study proposed a predictive model of the risk of developing breast cancer after detection of an ABL in order to avoid surgical removal of "low-risk" lesions. It also aimed to provide information on psychological experience, in particularly anxiety, to assist in the shared medical decision process. METHODS: Three hundred women undergoing surgery for ABL were included between 2015 and 2018 at 18 French centers. Women completed questionnaires before and after surgery assessing their level of anxiety (STAI-State, STAI-Trait), their level of tolerance to uncertainty, their perceived risk of developing a breast cancer, and their satisfaction with the management care. RESULTS: One hundred nighty nine patients completed the STAI-Status before and after surgery. Overall, a decrease in anxiety level (35.4 vs 42.7, P<0.001) was observed. Anxious temperament and greater intolerance to uncertainty were significantly associated swith decreased anxiety (33%), whereas younger age was associated with increased anxiety (8%). CONCLUSION: Surgery for ABL seems to be associated with only a few cases with an increase in anxiety and seems to increase the perception of the risk of developing breast cancer. Taking into account the psychological dimension remains in all cases essential in the process of shared therapeutic decision.

[Impact of the COVID-19 Outbreak on the management of patients with gynecological cancers]. / Impact de la pandémie de Covid-19 sur les modifications thérapeutiques des patientes atteintes de cancers gynécologiques.

OBJECTIVE: The exceptional health situation related to the SARS-Cov2 coronavirus pandemic (COVID-19) required a deep and very quickly adaptation of management practices in gynecological cancer. The main objective is to estimate the proportion of patients with treatment modifications. METHOD: This is a multicenter prospective study conducted in 3 university gynecological cancer departments (HCLyon, France) during the period of confinement (March 16 to May 11, 2020). All patients with non-metastatic breast cancer or gynecological cancer were included. The planned treatment, postponement, delay and organizational modifications (RCP, teleconsultations) were studied. RESULTS: Two hundred and five consecutive patients were included, average age 60.5±1.0. 7 patients (3.4%) had SARS-Cov-2 infection, 2 patients died. One hundred and twenty-two patients (59.5%) had a treatment maintained, 72 patients (35.1%) postponed, 11 patients (5.4%) cancelled. Of the 115 (56.1%) planned surgeries, 40 (34.8%) postponed, 7 cancelled (6.1%). 9 patients (7.8%) had a surgical modification. Of the 59 (28.8%) radiotherapy treatments scheduled, 24 (40.7%) postponed and 2 (3.4%) cancelled. Of the 56 (27.3%) chemotherapy treatment planned, 8 (14.3%) postponed and 2 (3.6%) cancelled. One hundred and forty-five patients (70.7%) have been discussed in multidisciplinary meeting. One hundred and fifty-eight patients (77%) had a teleconsultation system. CONCLUSION: Our study assessed the impact of the COVID-19 pandemic on therapeutic management of patients with gynecological cancer during the period of confinement. This will probably improve our management of an eventual epidemic rebound or future health crisis.

Surgical activity during the Covid-19 pandemic: Results for 112 patients in a French tertiary care center, a quality improvement study.

BACKGROUND: After the emergence of Covid-19 in China, Hubei Province, the epidemic quickly spread to Europe. France was quickly hit and our institution was one of the first French university to receive patients infected with Sars-COV2. The predicted massive influx of patients motivated the cancellation of all elective surgical procedures planned to free hospitalization beds and to free intensive care beds. Nevertheless, we should properly select patients who will be canceled to avoid life-threatening. The retained surgical indications are surgical emergencies, oncologic surgery, and organ transplantation. MATERIAL AND METHODS: We describe the organization of our institution which allows the continuation of these surgical activities while limiting the exposure of our patients to the Sars Cov2. RESULTS: After 4 weeks of implementation of intra-hospital protocols for the control of the Covid-19 epidemic, 112 patients were operated on (104 oncology or emergency surgeries and 8 liver transplants). Only one case of post-operative contamination was observed. No mortality related to Covid-19 was noted. No cases of contamination of surgical care personnel have been reported. CONCLUSION: We found that the performance of oncological or emergency surgery is possible, safe for both patients and caregivers.

[Fetal heart rate analysis: Evaluation of an in situ training program on cardiotocography interpretation during labor in the Auvergne-Rhône-Alpes region (France)]. / Formation à l'analyse du rythme cardiaque fœtal : évaluation d'un programme d'enseignement in situ au sein du réseau périnatal Auvergne-Rhône-Alpes.

OBJECTIVES: To evaluate an in situ training program on caradiotocography interpretation during labor in the Auvergne-Rhône-Alpes region (France). METHODS: Fifteen hospital maternity unit took part to an "outreach visit" training on fetal cardiotocography interpretation between November 2011 and 2015. Professionals were asked to answer to a 10 questions test based on the French classification of fetal heart rate, at inclusion (Test 0: T0), immediately after (Test 1: T1), and long time after the training (Test 2: T2). The mean score for each maternity (T0, T1, T2) was compared individually. Subgroup analysis considered the level of perinatal care of each maternity (level 1 or 2) and the type of practice (public or private). RESULTS: The study included 332 healthcare professionals belonging to 8 level 1 (53.5%) and 7 level 2 (47.7%) maternity units. The T0 mean score was 4.79 (IC 95% [4.54; 5.02]) instead of 6.71(IC 95% [6.49; 6.93]) at T1 (P<0.05). Seventeen professionals (22.9%) answered T2 with a mean time of 35.2 months (Median value: 40 months) and a mean score of 5.32. The mean score was significantly higher at T2 than at T0 (5.32-IC 95%[4.94-5.70] (P<0.001) but lower than the score at T1 (P<0.05). CONCLUSION: An "outreach visit" training on fetal cardiotocography interpretation improves theknowledge of healthcare professionals at short and long term.

[Contribution of ultrasound pulmonary ratio in pre-viable premature ruptures of membranes]. / Apport des ratio pulmonaires échographiques dans les ruptures prématurées précoces des membranes.

OBJECTIVE: To evaluate the ultrasound measurement of the observed-to-expected (o/e) lung-to-head ratio (LHR) and the Quantitative Lung Index (QLI) for the prediction of pulmonary hypoplasia in the pre-viable preterm premature ruptures of membranes (PPROM) before 24 weeks gestational age (GA). METHODS: Thirty-four patients with a PPROM before 24 weeks GA and who delivered a live birth between October 2008 and October 2015 at Croix-Rousse's hospital were included. The measurements of both the LHR (right, left and total) and the QLI (right, left) were retrospectively performed by ultrasounds during the latency period. The observed LHR was divided by the expected LHR, which was obtained from recent literature data. The primary outcome was the onset of a lethal pulmonary hypoplasia. Receiver operating characteristics (ROC) curves assessed the predictive value of these ultrasound measurements for pulmonary hypoplasia. RESULTS: The areas under the ROC curves (AUCs) for the right o/eLHR, the right QLI and the total o/e LHR measured by manually drawing the pulmonary area on the last ultrasound before the delivery, were respectively 0.87 [95% CI: 0.75-1], 0.83 [95% CI: 0.69-0.98] and 0.78 [95% CI: 0.51-1]. Only the total o/e LHR measurements remained associated with lethal pulmonary hypoplasia after adjusting for prematurity and persistent oligohydramnios. CONCLUSION: The right and total o/eLHR and the right QLI measurements might be helpful in predicting pulmonary hypoplasia in pre-viable PPROM.

Predictive factors of pathologic complete response of HER2-positive breast cancer after preoperative chemotherapy with trastuzumab: development of a specific predictor and study of its utilities using decision curve analysis.

PURPOSE: The aim of this study was to assess the Institut Gustave Roussy/M.D. Anderson Cancer Center (IGR/MDACC) nomogram in predicting pathologic complete response (pCR) to preoperative chemotherapy in a cohort of human epidermal growth factor receptor 2 (HER2)-positive tumors treated with preoperative chemotherapy with trastuzumab. We then combine clinical and pathological variables associated with pCR into a new nomogram specific to HER2-positive tumors treated by preoperative chemotherapy with trastuzumab. PATIENTS AND METHODS: Data from 270 patients with HER2-positive tumors treated with preoperative chemotherapy with trastuzumab at the Institut Curie and at the Georges François Leclerc Cancer Center were used to assess the IGR/MDACC nomogram and to subsequently develop a new nomogram for pCR based on multivariate logistic regression. Model performance was quantified in terms of calibration and discrimination. We studied the utility of the new nomogram using decision curve analysis. RESULTS: The IGR/MDACC nomogram was not accurate for the prediction of pCR in HER2-positive tumors treated by preoperative chemotherapy with trastuzumab, with poor discrimination (AUC = 0.54, 95% CI 0.51-0.58) and poor calibration (p = 0.01). After uni- and multivariate analysis, a new pCR nomogram was built based on T stage (TNM), hormone receptor status, and Ki67 (%). The model had good discrimination with an area under the curve (AUC) at 0.74 (95% CI 0.70-0.79) and adequate calibration (p = 0.93). By decision curve analysis, the model was shown to be relevant between thresholds of 0.3 and 0.7. CONCLUSION: To the best of our knowledge, ours is the first nomogram to predict pCR in HER2-positive tumors treated by preoperative chemotherapy with trastuzumab. To ensure generalizability, this model needs to be externally validated.

[Non-metastatic triple-negative breast cancer in 2016: Definitions and management]. / Tumeurs localisées du sein triple négatives en 2016 : définitions et prise en charge.

Triple-negative breast cancer (TN), as defined by the triple negativity in immunohistochemistry: the absence of estrogen receptor, progesterone receptor and the absence of overexpression or amplification of HER2, corresponds to 15 % of invasive breast cancers. This is a very heterogeneous group of tumors both at the genomic and transcriptomic level and at morphological, clinical and prognostic level. Although there are some good prognosis forms, the majority of TN tumors is characterized by a poor prognosis with a greater frequency of visceral metastases and a maximum risk of relapse in the first two years after diagnosis. Systemic adjuvant treatment with chemotherapy is almost always indicated. The surgical treatment and radiotherapy treatment should be comparable to the other subtypes and obey the same rules of oncologic surgery. TN tumors are not associated with a higher risk of locoregional relapse after conservative treatment and adjuvant radiotherapy. Optimization of systemic therapies is currently and for the last decade a challenge. A number of targeted therapies and efficiency biomarkers identification of these targeted therapies is essential to allow significant progress in optimizing systemic therapy for these tumors.

[Distribution of blood loss during vaginal delivery and cesarean section]. / Analyse descriptive du volume des pertes sanguines au cours de l'accouchement par voie basse et par césarienne.

OBJECTIVES: To describe the distribution of the volume of blood loss during vaginal and cesarean deliveries among women who delivered after 24 weeks of gestation. MATERIALS AND METHODS: A descriptive study of the distribution of blood loss by delivery route and for all patients after 24 weeks of gestation over a period of two years in a type III maternity. Patient and delivery characteristics were collected and blood loss was measured prospectively based on weighing pads and the use of a collector bag for vaginal deliveries, a suction cannula for cesareans sections. The following parameters were calculated: the mean (±SD), the median, interquartile range (IQR), the 5th and 95th percentile. RESULTS: Seven thousand nine hundreds and eight patients were included. After vaginal delivery (n=6134), the mean volume of bleeding was equal to 180.1 mL (± 224.7 mL), the median to 100mL (IQR [100-200]), the 95th percentile to 500 mL [CI 95% 500-550]. For cesarean sections (n=1774), the mean volume of bleeding was equal to 557.9mL (± 496.2 mL), the median volume of blood loss to 400 mL (IQR [300-700]), the 95th percentile to 1300 mL [CI 95% 1200-1500]. CONCLUSION: The distribution of blood loss after cesarean was significantly higher than the distribution of blood loss after vaginal delivery.

[Frequency, causes and risk factors of postpartum haemorrhage: a population-based study in 106 French maternity units]. / Incidence, étiologies et facteurs de risque de l'hémorragie du post-partum : étude en population dans 106 maternités françaises.

OBJECTIVE: To estimate the incidence, to describe the aetiology and to identify the risk factors of postpartum haemorrhage (PPH). MATERIAL AND METHOD: Prospective study conducted in 106 French maternity units of six perinatal networks between December 2004 and November 2006. PPH was defined by a blood loss superior to 500 mL or necessitating an examination of the uterus, or a peripartum haemoglobin drop superior to 2 g/dL. Severe PPH was defined by at least one of these criteria : peripartum haemoglobin drop superior or equal to 4 g/dL, embolization, conservative surgical procedure, hysterectomy, transfusion, transfer to intensive care or death. RESULTS: The incidence of PPH was 6.4% [CI 95% 6.3-6.5] with variations between maternity units from 1.5% to 22.0%; incidence of severe PPH was 1.7% [CI 95% 1.6-1.8] with variations between units from 0% to 4%. Atony was the main aetiology of PPH, whatever the mode of delivery and severity. The risk factors identified were those classically described in the literature. CONCLUSION: In these six French perinatal networks, in 2005-2006, the PPH profile was characterized by an incidence of severe forms higher than previous population-based estimates from other countries. This suggests a more frequent aggravation of PPH and the implication of inadequate PPH management.

Patterns of recurrence of obstructing colon cancers after surgery for cure: a population-based study.

AIM: Little is known about patterns of recurrence in obstructing colon cancer (OCC) at a population level. The aim of this study was to determine the risk of recurrence following potentially curative surgery in OCC compared with that in uncomplicated colon cancer (CC). METHOD: Data were obtained from the population-based digestive cancer registry of Burgundy (France). Local and distant failure rates were calculated using actuarial methods. A multivariate analysis was performed using a Cox model. RESULTS: Obstructing colon cancer represented 8.5% of all colon cancers resected with curative intent (n = 3375). The 5-year cumulative local recurrence rate was 14.2% for OCC and 7.6% for nonobstructing CC (P = 0.003). In the multivariate analysis, obstruction was an independent risk factor for local recurrence [hazard ratio 1.53 (1.01-2.34), P = 0.047]. The risk of local recurrence increased with advanced stage and age at diagnosis. The 5-year cumulative rate for distant metastases was also higher in OCC than in nonobstructing CC (36.1 vs 23.1%; P < 0.001). The relative risk of distant metastasis was borderline significant in the multivariate analysis [hazard ratio 1.25 (0.99-1.59), P = 0.057]. Stage at diagnosis, macroscopic type of growth, period of diagnosis and sex were also significant prognostic factors. Age and subsite were not significant in the multivariate analysis. CONCLUSION: It is possible to conduct special surveys in population-based registries to determine the recurrence rate of CC. Recurrence remains a substantial problem and is more frequent in OCC than in nonobstructing CC. Efforts must be made to diagnose CC earlier. Mass screening is a promising approach.

Association between fibrinogen level and severity of postpartum haemorrhage: secondary analysis of a prospective trial.

BACKGROUND: The aim of the study was to determine whether the fibrinogen level at diagnosis of postpartum haemorrhage (PPH) is associated with the severity of bleeding. METHODS: This is a secondary analysis of a population-based study in 106 French maternity units identifying cases of PPH prospectively. PPH was defined by a blood loss exceeding 500 ml during the 24 h after delivery or a peripartum haemoglobin decrease of more than 20 g litre(-1). This analysis includes 738 women with PPH after vaginal delivery. Fibrinogen levels were compared in patients whose PPH worsened and became severe and those whose PPH remained non-severe. Severe PPH was defined as haemorrhage by occurrence of one of the following events: peripartum haemoglobin decrease ≥ 40 g litre(-1), transfusion of concentrated red cells, arterial embolization or emergency surgery, admission to intensive care, or death. RESULTS: The mean fibrinogen concentration at diagnosis was 4.2 g litre(-1) [standard deviation (sd)=1.2 g litre(-1)] among the patients without worsening and 3.4 g litre(-1) (sd=0.9 g litre(-1)) (P<0.001) in the group whose PPH became severe. The fibrinogen level was associated with PPH severity independently of other factors [adjusted odds ratio=1.90 (1.16-3.09) for fibrinogen between 2 and 3 g litre(-1) and 11.99 (2.56-56.06) for fibrinogen <2 g litre(-1)]. CONCLUSIONS: The fibrinogen level at PPH diagnosis is a marker of the risk of aggravation and should serve as an alert to clinicians.

[Practices for management of grave postpartum haemorrhage after vaginal delivery: a population-based study in 106 French maternity units]. / Prise en charge des hémorragies graves du post-partum après un accouchement par voie basse : étude en population dans 106 maternités françaises.

OBJECTIVES: Describe management of severe postpartum haemorrhages (PPH) and its compliance with national guidelines and identify determinants of non-optimal care. PATIENTS AND METHOD: Population-based cohort study of 1379 women with severe PPH due to uterine atony after vaginal delivery, conducted in 106 French maternity units between December 2004 and November 2006. Severe PPH was defined by a peripartum haemoglobin drop of 4g/dL or more, blood loss of 1000 mL or more, hysterectomy, or transfer to intensive care for PPH. The frequency of each recommended procedure for the management of PPH was described. Associations between quality of care and both individual and institutional characteristics were assessed by univariate analysis and multivariate logistic regression. RESULTS: Management of severe PPH was not optimal in 65.9% of cases. The recommended components that were applied least often were administration of second line uterotonics, and transfusion of patients with a low haemoglobin. After adjustment for individual characteristics, the risk of either non- or suboptimal care was significantly higher in non-university public maternity units (aOR 2.62 [95% CI: 1.49-4.54]) compared with university hospital units, in units with fewer than 2000 annual deliveries (aOR 2.32 [95% CI: 1.49-3.57]), and in units without an obstetrician always present (aOR 1.96 [95% CI: 1.26-3.03]). CONCLUSIONS: Management practices for severe PPH can be improved, to an extent that varies by component of care and type of hospital. A qualitative approach should help to identify the individual and organizational factors explaining why guidelines are not fully applied.

[Does persistent occiput posterior position increase the risk of severe perineal laceration?]. / Les présentations postérieures augmentent-elles le risque de déchirures périnéales sévères?

OBJECTIVE: To assess the risk of severe perineal lacerations (III and IV degrees) during vaginal deliveries in occiput posterior position. PATIENTS AND METHODS: We conducted a retrospective cohort study of 9097 vaginal deliveries in a teaching hospital's maternity between January 1st 2005 and December 31st 2008. Risk factors associated with tears of the 3rd or 4th degree were studied by a multivariate logistic regression. RESULTS: Severe perineal lacerations occurred in 1.69% of cases (n=152) and did not significantly vary between 2005 and 2008. Parity was a protective factor (OR 0.42; P<0.001; IC(95%) 0.29-0.60) whereas instrumental extraction was associated with an increased risk: vacuum (OR 3.95; P<0.001, IC(95%) 2.23-7.00) and forceps (OR 3.55; P<0.001, IC(95%) 2.33-5.42). macrosomia. Risks were also increased in fetal macrosomia and episiotomy did not protect the mother (respectively OR 1.41 P<0.001, IC(95%) 1.19-1.68 and OR 1.73; P<0.001, IC(95%) 1.16-2.57). Persistent occiput posterior position was not significantly associated with an anal sphincter injury (OR=1.70 P=0.059; IC(95%) 0.98-2.94). DISCUSSION AND CONCLUSION: In our series, occiput posterior position did not significantly impact the risk of severe perineal laceration. A manual rotation of the fetal head should be performed in case of associated risk factors.

[Evolution of adherence to guidelines for prevention of group B streptococcal infections]. / Évolution de l'application d'un protocole de prévention contre les infections materno-foetales à streptocoque de groupe B.

OBJECTIVE: Assess the evolution in implementation of neonatal group B streptococcal infections prevention program in the Aurore network, between 2004 and 2009. PATIENTS AND METHODS: A cross-sectional study was conducted during one week in the whole maternity units of the Aurore network about implementation of the neonatal streptococcal infection prevention program. Deliveries occurring after 37 weeks of gestation were included. Every stage required by the prevention program was registered for every delivery. Results obtained during this study were compared with those obtained in 2004. RESULTS: Seven hundred and forty-four patients were included in 2004 and 618 in 2009. Vaginal swab rate was 96.3% in 2009 and 91.1% in 2004 (P<0.001), with a positive rate of 10.2 and 14.2%, respectively (P=0.041). Antibiotic infusion rates during delivery did not increase significantly. Clinical and biological surveillance of exposed newborns was significantly increased (P<0.001). No neonatal infection was observed during the study among newborns included in the program. CONCLUSION: Sensitization of caregivers about neonatal streptococcal infection prevention seems to be efficient to increase the application of the prevention program written by the Aurore network.
