Association Between First-Trimester Bleeding and Retained Placenta Requiring Dilatation and Curettage.

OBJECTIVE: Early subchorionic hemorrhage may lead to a disruption in the placental-uterine matrix, which may result in an adherence of the placenta to the endometrium. We evaluated the effect of a first-trimester bleed on the need for a post-vaginal delivery dilatation and curettage (D&C) for removal of retained placenta. METHODS: We conducted a case-control study at a tertiary care centre between 2012 and 2016. Patients identified through medical records as having required a post-vaginal delivery D&C for retained placenta were considered cases and were matched 1:5 with patients delivering vaginally within 1 week who did not require a D&C. History of first-trimester bleeding and subchorionic hemorrhage were identified through chart review. Conditional logistic regression analyses estimated the effect of a first-trimester bleed on the requirement for D&C for retained placenta. Models were adjusted for maternal age and previous uterine surgery. RESULTS: There were 68 cases of retained placenta requiring D&C, for an estimated 3 in 1000 deliveries. Patients requiring D&C were slightly older than controls but were otherwise comparable with respect to baseline demographic characteristics. In adjusted analyses, patients who required a postpartum D&C were more likely than controls to have had a first-trimester bleed at 11.8% and 0.6%, respectively (OR 25.3; 95% CI 4.7-135.4, P < 0.001). Postpartum D&C for retained placenta was associated with postpartum hemorrhage, need for blood transfusion, and manual removal of placenta. CONCLUSION: First-trimester bleeding should be considered a high-risk determinant for post-vaginal delivery D&C for retained placenta and for severe postpartum hemorrhage.

Management of New-Onset Atrial Fibrillation in Pregnancy: When Should Early Delivery Be Considered?

BACKGROUND: The hemodynamic and physiological changes of pregnancy may predispose women to cardiac arrhythmias such as atrial fibrillation (AF). Nevertheless, new-onset AF in pregnancy remains rare, and treatment is challenging. Current recommendations are to treat pregnant women with AF as non-pregnant adults, by using pharmacological or synchronized electrical cardioversion, without mention of gestational age or possibility of delivery. CASE: A 23-year-old nulliparous woman developed new-onset symptomatic AF at 362 weeks gestation, but presented to our hospital was delivered at 364 weeks gestation. Beta-blockers were administered for heart rate control. After 48 hours, the decision was made to proceed with delivery rather than cardioversion. The patient's arrhythmia resolved spontaneously postpartum without further treatment. CONCLUSION: In pregnant patients near or at term, delivery should be considered in the management of new-onset AF after consultation with cardiology, anaesthesiology, and maternal-fetal medicine.

Understanding factors affecting collaboration between midwives and other health care professionals in a birth center and its affiliated Quebec hospital: a case study.

BACKGROUND: A better understanding of the processes of collaboration between midwives who work in the birthing centers, and hospital-based obstetricians, family physicians and nurses may promote cooperation among professionals providing maternity care in both institutions. The aim of this research was to explore the barriers and facilitators of the interprofessional and interorganizational collaboration between midwives in birthing centers and other health care professionals in hospitals in Quebec. METHODS: A case study design was adopted. Data were collected through semi-structured interviews with midwives, multidisciplinary professionals and administrators, through direct observation of activities in maternity units and field notes, and a variety of organizational and policy documents and archives. A qualitative thematic analysis method was used for analyzing transcribed verbatim. RESULTS: The study suggests the close intertwinement between interactional, organizational and systemic factors in regard to barriers and opportunities for collaboration between midwives in birthing centers, and physicians and nurses in hospitals in Quebec. At interactional level, our findings show a conflict in scope of midwifery practice, myth about midwives, pre-judgment, and lack of communication skills between health care providers in the studied birthing center and hospital. At the organizational level, this investigation shows that although midwives have complete access to the hospital with which a formal agreement was signed, they were not integrated in hospital because of lack of interest of midwives and differences in philosophy and scope of practice among healthcare professionals as well as the culture of organizations. At a systemic level, in spite of excessive demand for midwifery care, there are not enough midwives to cover these demands. CONCLUSION: Maternity care professionals require taking a collaborative approach in working and the boundaries of responsibility need to be redrawn. The inter-professional collaborative work between midwives and other maternity care professionals is crucial to improve access and women's choices for maternity care in Canada. Although having collaborative and multidisciplinary teamwork is a goal of maternity care systems, it is hard to achieve.

Effect of Uterine Cavity Sonographic Measurements on Medical Management Failure in Women With Early Pregnancy Loss.

OBJECTIVES: Medical management is commonly used among women with early pregnancy failure. The purpose of our study was to evaluate uterine content sonographic measurements for predicting medical management failure in early pregnancy loss. METHODS: We conducted a retrospective cohort study in a university-affiliated hospital center including all women discharged from the emergency department (ED) with a diagnosis of early pregnancy failure who had medical management with misoprostol between 2011 and 2013. Only women with sonograms available for review were included in our study. All images were reviewed and the following cavity measurements, excluding the endometrial lining, were measured: cavity anteroposterior distance, cavity longitudinal distance, cavity transverse distance, and cavity volume. Logistic regression analysis was used to identify measurements that were independently associated with a subsequent need for dilation and curettage (D&C) and an unplanned return to the ED. RESULTS: Among 823 women presenting to the ED with first-trimester bleeding, 227 met inclusion criteria. Of all measurements evaluated, the cavity anteroposterior distance was found to be independently associated with D&C and an unplanned return to the ED. When a cavity anteroposterior distance cutoff of 15 mm was used, women were more likely to require D&C (adjusted odds ratio, 2.65; 95% confidence interval, 1.31-5.36; P< .01) and to have an unplanned return to the ED (adjusted odds ratio, 2.59; 95% confidence interval, 1.41-4.79; P < .01). In women with a cavity anteroposterior distance of less than 15 mm, 87.1% had successful medical management of early pregnancy loss, and 80.0% did not require an unplanned return to the ED. CONCLUSIONS: Although there is a need for further validation, patients identified as having a cavity anteroposterior distance of less than 15 mm should be considered good candidates for successful medical management.

Pregnancy outcomes in women with bariatric surgery as compared with morbidly obese women.

OBJECTIVE: Pregnancies among morbidly obese women are associated with serious adverse maternal and neonatal outcomes. Our study objective is to evaluate the effect of bariatric surgery on obstetrical outcomes. METHODS: We carried out a retrospective cohort study using the healthcare cost and utilization project - Nationwide Inpatient Sample from 2003 to 2011 comparing outcome of births among women who had undergone bariatric surgery with births among women with morbid obesity. Logistic regression was used to estimate the adjusted effect of bariatric surgery on maternal and newborn outcomes. RESULTS: There were 8 475 831 births during the study period (221 580 (2.6%) in morbidly obese women and 9587 (0.1%) in women with bariatric surgery). Women with bariatric surgery were more likely to be Caucasian and ≥35 years old as compared with morbidly obese women. As compared with women with morbid obesity, women with bariatric surgery had lower rates of hypertensive disorders, premature rupture of membrane, chorioamnionitis, cesarean delivery, instrumental delivery, postpartum hemorrhage, and postpartum infection. Induction of labor, postpartum blood transfusions, venous thromboembolisms, and intrauterine fetal growth restriction were more common in the bariatric surgery group. There were no differences observed in preterm births, fetal deaths, or reported congenital anomalies. CONCLUSION: In general, women who undergo bariatric surgery have improved pregnancy outcomes as compared with morbidly obese women. However, the bariatric surgery group was more likely to have venous thromboembolisms, to require a blood transfusion, to have their labor induced and to experience fetal growth restriction.

Primary Fallopian Tube Clear Cell Adenocarcinoma in Pregnancy: Case Presentation and Review of the Literature.

Primary fallopian tube cancer in pregnancy is rare and is even more so for the clear cell variant. Our case is the third case of primary fallopian tube cancer in pregnancy and the first case of clear cell adenocarcinoma of the fallopian tube in pregnancy. The patient presented with increasing pelvic pain starting in the second trimester. Serial ultrasound evaluations were performed and revealed a rapidly growing complex adnexal mass adjacent to the uterus. Her pregnancy was further complicated by spontaneous preterm labor and she delivered prematurely per vaginam at 31 weeks. She underwent an urgent laparotomy in the immediate postpartum period for acute aggravation of her right pelvic pain and fever. The diagnosis of tubal clear cell adenocarcinoma was subsequently made on histopathology examination.

Expectant parents' understanding of the implications and management of fever in the neonate.

OBJECTIVE: We estimated the extent to which Canadian expectant parents would seek medical care in a febrile neonate (age 30 days or less). We also evaluated expectant parents' knowledge of signs and symptoms of fever in a neonate, and explored the actions Canadian expectant parents would take to optimize the health of their child. METHODS: We conducted a cross-sectional survey of a sample of expectant parents from a large urban center in Canada. We recruited participants from waiting rooms in an obstetrical ultrasound clinic located in an urban tertiary care hospital in Montreal, Canada. We asked participants nine questions about fever in neonates including if, and how, they would seek care for their neonate if they suspected he/she were febrile. RESULTS: Among the 355 respondents, (response rate 87%) we found that 75% of parents reported that they would take their febrile neonate for immediate medical assessment, with nearly one fifth of the sample reporting that they would not seek medical care. We found no significant associations between the choice to seek medical care and expectant parents socio-demographic characteristics. CONCLUSIONS: Despite universal access to high quality health care in Canada, our study highlights concerning gaps in the knowledge of the care of the febrile infant in one fifth of expectant parents. Physicians and health providers should strive to provide early education to expectant parents about how to recognize signs of fever in the neonate and how best to seek medical care. This may improve neonatal health outcomes in Canada.

Oxidative conditions prevail in severe IUGR with vascular disease and Doppler anomalies.

OBJECTIVE: Intrauterine growth restriction (IUGR) and prenatal exposure to oxidative stress are thought to lead to increased risks of cardiovascular disease later in life. The objective of the present study was to document whether cord blood oxidative stress biomarkers vary with the severity of IUGR and of vascular disease in the twin pregnancy model in which both fetuses share the same maternal environment. METHODS: This prospective cohort study involved dichorionic twin pairs, with one co-twin with IUGR. Oxidative stress biomarkers were measured in venous cord blood samples from each neonate of 32 twin pairs, and compared, according to severity of IUGR (IUGR <5th percentile), Doppler anomalies of the umbilical artery and early onset IUGR (in the second trimester) of the growth restricted twin. RESULTS: Oxidized Low-Density Lipoproteins (oxLDL) and Malondialdehyde (MDA) concentrations were increased proportionally in cases of severe IUGR. OxLDL concentrations were also increased in cases of IUGR with Doppler anomaly. CONCLUSION: Our data indicate that severe IUGR, is related to a derangement in redox balance, illustrated by increased venous cord blood oxidative stress biomarkers concentrations. Severe IUGR and IUGR with abnormal Doppler can be translated into conditions with intense oxidative stress.

Incidence, indications, and predictors of adverse outcomes of postpartum hysterectomies: 20-year experience in a tertiary care centre.

OBJECTIVE: Postpartum hysterectomy is an uncommon yet serious obstetric procedure associated with maternal morbidity and mortality. The objectives of our study were to assess the incidence of and indications for PH and to identify predictors of massive hemorrhage and coagulopathy. METHODS: We conducted a retrospective cohort study on all cases of PH performed at the Jewish General Hospital, McGill University, between 1992 and 2011. Data were collected from individual patient charts and logistics regression models were used to evaluate predictors of adverse events. RESULTS: Over a 20-year study period, there were 76 938 live births and 67 postpartum hysterectomies for an overall incidence of 0.87/1000. Although overall PH rates increased over time predominantly because of increasing rates of planned PH for placental abnormalities, there was a decrease in unplanned emergency postpartum hysterectomies. The main indications for PH were abnormal placentation (64.2%) and postpartum hemorrhage (26.9%). In adjusted analysis, the risk of requiring massive blood transfusion was increased when PH was performed after vaginal delivery or Caesarean section (OR 102.1; 95% CI 4.22 to 2468) and in association with postpartum hemorrhage (OR 9.1; 95% CI 1.3 to 64.3). The risk of massive hemorrhage was lower if occlusive balloons were placed antenatally in the uterine arteries (OR 0.13; 95% CI 0.03 to 0.68) and if PH was performed by a dedicated experienced surgeon (OR 0.23; 95% CI 0.06 to 0.86). CONCLUSION: Although overall rates of PH are increasing, antenatal recognition of placental pathologies have resulted in fewer postpartum hysterectomies being done as emergencies. The use of occlusive balloons in the uterine arteries and having the procedure performed by a dedicated surgeon skilled in performing postpartum hysterectomy can reduce overall serious morbidity.

Objectif : L'hystérectomie postpartum (HP) est une intervention obstétricale peu courante, mais grave, qui est associée à de la morbidité et à la mortalité chez la mère. Les objectifs de notre étude étaient d'évaluer l'incidence de l'HP et ses indications, et d'identifier les facteurs prédictifs de l'hémorragie massive et de la coagulopathie. Méthodes : Nous avons mené une étude de cohorte rétrospective qui portait sur tous les cas d'HP menés à l'Hôpital général juif de l'Université McGill entre 1992 et 2011. Les données ont été tirées des dossiers des patientes ciblées et nous avons utilisé des modèles de régression logistique pour évaluer les facteurs prédictifs d'événements indésirables. Résultats : Au cours de la période d'étude de 20 ans, nous avons constaté 76 938 naissances vivantes et 67 cas d'hystérectomie postpartum, l'incidence globale de cette dernière étant donc de 0,87/1 000. Bien que les taux globaux d'HP aient connu une hausse avec le temps (principalement en raison de la hausse des taux d'HP planifiée en raison de la présence d'anomalies placentaires), nous avons constaté une baisse du nombre de cas d'hystérectomie postpartum d'urgence (non planifiées). Les principales indications de l'HP ont été la présence d'une placentation anormale (64,2 %) et celle d'une hémorragie postpartum (26,9 %). Dans le cadre d'une analyse corrigée, nous avons constaté que le risque de nécessiter une transfusion massive de sang connaissait une hausse lorsqu'une HP était menée à la suite d'un accouchement vaginal ou d'une césarienne (RC, 102,1; IC à 95 %, 4,22 - 2 468), ainsi qu'en association avec la présence d'une hémorragie postpartum (RC, 9,1; IC à 95 %, 1,3 - 64,3). Le risque d'hémorragie massive était moindre lorsque des ballonnets occlusifs étaient placés, avant la naissance, dans les artères utérines (RC, 0,13; IC à 95 %, 0,03 ­ 0,68) et lorsque l'HP était menée par un chirurgien d'expérience spécialisé (RC, 0,23; IC à 95 %, 0,06 - 0,86). Conclusion : Bien que les taux globaux d'HP soient en hausse, la capacité de reconnaître la présence de pathologies placentaires pendant la période prénatale s'est soldée en un nombre moindre de cas d'hystérectomie postpartum de nature urgente. L'utilisation de ballonnets occlusifs dans les artères utérines et le fait d'avoir recours à un chirurgien d'expérience spécialisé dans la tenue d'interventions d'hystérectomie postpartum peuvent atténuer le taux global de morbidité grave.

Prenatal and postnatal features of mesenchymal hamartoma of the chest wall: case report and literature review.

Mesenchymal hamartoma of the chest wall is a rare, benign chondro-osseous tumor of the bone. Although it most commonly presents at birth or soon after, prenatal detection is rare. We report a case of prenatally detected mesenchymal hamartoma, and provide the rationale, details, and outcomes of our management. The literature is reviewed, with particular attention to prenatal detection and postnatal management options.

Pregnancies in young adolescent mothers: a population-based study on 37 million births.

OBJECTIVES: Pregnancy in young adolescents is often understudied. The objective of our study was to evaluate the effect of young maternal age on adverse obstetrical and neonatal outcomes. METHODS: We conducted a population-based cohort study using the Center for Disease Control and Prevention's Linked Birth-Infant Death and Fetal Death data on all births in the US between 1995 and 2004. We excluded all births of gestational age under 24 weeks and those with reported congenital malformations or chromosomal abnormalities. Maternal age was obtained from the birth certificate and relative risks estimating its effect on obstetrical and neonatal outcomes were computed using unconditional logistic regression analysis. RESULTS: 37,504,230 births met study criteria of which 300,627 were in women aged <15 years with decreasing rates from 11/1,000 to 6/1,000 over a 10-year period. As compared to women 15 years and older, women <15 were more likely to be black and Hispanic, less likely to have adequate prenatal care, and more likely to not have had any prenatal care. In adjusted analysis, births to women <15 were more likely to be IUGR, born under 28, 32, and 37 weeks' gestation and to result in stillbirths and infant deaths. Prenatal care was protective against infant deaths in women < 15 years of age. CONCLUSION: Although public health initiatives have been successful in decreasing rates of young adolescent pregnancies, these remain high risk pregnancies that may benefit from centers capable of ensuring adequate prenatal care.

Oxidized low-density lipoproteins in cord blood from neonates with intra-uterine growth restriction.

OBJECTIVE: We verified whether oxidative stress indices (oxidized low-density lipoproteins and malondialdehyde) and inflammatory biomarkers (circulating C-reactive protein, interleukin-6, tumour necrosis factor-α, serum amyloid A and soluble intercellular vascular cell adhesion molecule) are increased in the umbilical vein of placental insufficiency induced intra-uterine growth restricted neonates. STUDY DESIGN: The prospective cohort study, involving 3 tertiary care centers, consists of 200 consecutively recruited pregnant women carrying twins. We chose the twin pregnancy model because both fetuses share the same maternal environment, thereby avoiding potential confounding factors when comparing oxidative stress and inflammation biomarkers. We analysed only twin pairs with one with intra-uterine growth restriction (N=38) defined as fetal growth<10th percentile with abnormal Doppler of the umbilical artery. Blood samples were taken at birth from the umbilical vein. Intra-pair comparisons on the biomarkers were performed using the Student paired t-test. RESULTS: We observed increased cord blood levels of oxidized low-density lipoproteins, (2.394 ± .412 vs 1.296 ± .204, p=.003) but not of malondialdehyde in growth restricted neonates when compared to their normal counterparts. Although indices of inflammation tended to be increased in cord blood from growth restricted newborns, the difference did not reach statistical significance. CONCLUSION: In the twin model, intra-uterine growth restriction is associated with low-density lipoprotein oxidation without apparent dysregulation of inflammation biomarkers. CONDENSATION: Increased oxidized low-density lipoproteins are observed in growth restricted twins compared to their co-twins with normal growth at birth.

Predicting outcome in primary fetal hydrothorax.

OBJECTIVE: This study examines the role of serial ultrasound in predicting fetal outcomes based on progress, resolution or stability of pleural effusions in primary fetal hydrothorax (PFHT). METHODS: Records from consecutive cases of fetal pleural effusions referred to the fetal echocardiography unit over a 12-year period were reviewed. Study patients underwent thorough investigation to rule out secondary causes of pleural effusions. The clinical course was monitored with serial ultrasound studies every 2 weeks until delivery. Pleurocentesis and pleuroamniotic shunts were performed in select cases of PFHT. Fetal survival was the primary outcome variable. RESULTS: Eighteen of 44 patients referred for perinatal evaluation of fetal pleural effusions met the study criteria for PFHT. Diagnosis was made at 28 +/- 7 weeks and fetuses delivered at 35 +/- 3 weeks' gestational age. Overall survival was 78%. Effusion progression, greater effusion ratios, earlier gestational age at delivery, and lower Apgar scores at birth were associated with poor outcome. Conservative management was appropriate for most cases. CONCLUSIONS: Serial ultrasound studies to evaluate the clinical course of the pleural effusions are essential in the management of PFHT. Expectant management of stable and resolving effusions was appropriate in all cases.

Prediction of growth discordance in twins with the use of abdominal circumference ratios.

OBJECTIVE: The purpose of this study was to assess the accuracy of sonographic prediction of twin birth weight discordance using the abdominal circumference ratio. STUDY DESIGN: This was a prospective cohort of diamniotic twin gestations that underwent serial ultrasound examinations every 2 to 4 weeks from 11 to 38 weeks of gestation. Birth weight discordance was defined as > or =25% difference in birth weight, relative to the larger twin. The sensitivity, specificity, and predictive values for the abdominal circumference ratio were assessed for the prediction of growth discordance. RESULTS: Of 503 diamniotic twin pregnancies, 64 pregnancies (12.7%) had discordant fetal growth. The abdominal circumference ratio could be measured consistently throughout gestation in 100% of twin pairs. Receiver operating curve analysis showed that the abdominal circumference ratio was a good predictor of birth weight discordance (area under the curve = 0.80). An abdominal circumference ratio cutoff of 0.93 yielded a sensitivity and specificity of 61% and 84%, respectively. CONCLUSION: Twin birth weight discordance may be predicted at any gestational age with an abdominal circumference ratio <0.93.

Management options for preterm labour in Canada.

OBJECTIVES: (1) To determine the current use of treatment options for preterm labour and (2) to review the relative safety and efficacy of each class of tocolytic agent. METHODS: MEDLINE and the Cochrane Library were searched using the terms "preterm delivery," "preterm labour," and "tocolysis" alone, and in combination with the terms "betamimetics," "ritodrine," "magnesium sulfate," "calcium channel blockers," "nifedipine," "prostaglandin synthetase inhibitors," "indomethacin," "glyceryl trinitrate," "nitroglycerin," "oxytocin antagonists," and "atosiban." Randomized controlled trials (RCTs) that compared the effect of a tocolytic with a placebo or other tocolytic in women with preterm labour were selected. Trials were assessed according to Jadad's validated quality scale for assessing the quality of RCTs. Thirty two RCTs retrieved met the inclusion criteria. Information not evident from RCTs was sought from non-randomized clinical trials, cohort studies, case control studies, case series, and case reports. Data from the Canadian Survey on Tocolytic Use was obtained directly from the Society of Obstetricians and Gynaecologists of Canada (SOGC). RESULTS: The available evidence on the use of tocolytics to prolong pregnancy fails to show benefits in neonatal survival and reduced disability. This uncertainty of benefit makes the issue of fetal and maternal drug toxicity more important. There is great concern among SOGC members over the lack of effective and safe treatment options for the management of preterm labour. CONCLUSIONS: Further well-designed placebo-controlled trials are necessary to study the efficacy and safety of tocolytics in managing preterm labour.
