Outcome and Treatment of Antenatally Diagnosed Nonimmune Hydrops Fetalis.

INTRODUCTION: The objectives of this study were to evaluate the outcome of nonimmune hydrops fetalis in an attempt to identify independent predictors of perinatal mortality. MATERIAL AND METHODS: A retrospective cohort study was conducted including all cases of nonimmune hydrops from two tertiary care centers. Perinatal outcome was evaluated after classifying nonimmune hydrops into ten etiological groups. We examined the effect of etiology, site of fluid accumulation, and gestational age at delivery on postnatal survival. Neonatal mortality and hospital discharge survival were compared between the expectant management and fetal intervention groups among those with idiopathic etiology. RESULTS: A total of 142 subjects were available for analysis. Generally, nonimmune hydrops carried 37% risk of neonatal mortality and 50% chance of survival to discharge, which varies markedly based on the underlying etiology. Ascites was an independent predictor of perinatal mortality (p value = 0.003). There was nonsignificant difference in neonatal mortality and hospital discharge survival among idiopathic cases that were managed expectantly versus those in whom fetal intervention was carried out. DISCUSSION: The outcome of nonimmune hydrops varies largely according to the underlying etiology and the presence of ascites is an independent risk factor for perinatal mortality. In our series, fetal intervention did not offer survival advantage among fetuses with idiopathic nonimmune hydrops.

Multidisciplinary team learning in the management of the morbidly adherent placenta: outcome improvements over time.

BACKGROUND: Morbidly adherent placenta (MAP) is a serious obstetric complication causing mortality and morbidity. OBJECTIVE: To evaluate whether outcomes of patients with MAP improve with increasing experience within a well-established multidisciplinary team at a single referral center. STUDY DESIGN: All singleton pregnancies with pathology-confirmed MAP (including placenta accreta, increta, or percreta) managed by a multidisciplinary team between January 2011 and August 2016 were included in this retrospective study. Turnover of team members was minimal, and cases were divided into 2 time periods so as to compare 2 similarly sized groups: T1 = January 2011 to April 2014 and T2 = May 2014 to August 2016. Outcome variables were estimated blood loss, units of red blood cell transfused, volume of crystalloid transfused, massive transfusion protocol activation, ureter and bowel injury, and neonatal birth weight. Comparisons and adjustments were made by use of the Student t test, Mann-Whitney U test, χ2 test, analysis of covariance, and multinomial logistic regression. RESULTS: A total of 118 singleton pregnancies, 59 in T1 and 59 in T2, were managed during the study period. Baseline patient characteristics were not statistically significant. Forty-eight of 59 (81.4%) patients in T1 and 42 of 59 (71.2%) patients in T2 were diagnosed with placenta increta/percreta. The median [interquartile range] estimated blood loss (T1: 2000 [1475-3000] vs T2: 1500 [1000-2700], P = .04), median red blood cell transfusion units (T1: 2.5 [0-7] vs T2: 1 [0-4], P = .02), and median crystalloid transfusion volume (T1: 4200 [3600-5000] vs T2: 3400 [3000-4000], P < .01) were significantly less in T2. Also, a massive transfusion protocol was instituted more frequently in T1: 15/59 (25.4%) vs 3/59 (5.1%); P < .01. Neonatal outcomes and surgical complications were similar between the 2 groups. CONCLUSION: Our study shows that patient outcomes are improved over time with increasing experience within a well-established multidisciplinary team performing 2-3 cases per month. This suggests that small, collective changes in team dynamics lead to continuous improvement of clinical outcomes. These findings support the development of centers of excellence for MAP staffed by stable, core multidisciplinary teams, which should perform a significant number of these procedures on an ongoing basis.

Labia minora hypertrophy: causes, impact on women's health, and treatment options.

INTRODUCTION AND HYPOTHESIS: We provide a review of the literature about the onset and development of hypertrophy of the labia minora, together with some expert opinions on the appropriateness of labiaplasty. METHODS: We searched PubMed and used popular search engines, with a greater emphasis on the physiology and hormone-mediated metabolism of these structures, and less emphasis on their surgical treatment. RESULTS: We describe major embryological, cytological, and biochemical features of this anatomical part and summarize the clinical aspects of its hypertrophy, evaluating types of discomfort reported by women and the medical treatments available. Also, based on what is known about the artificial elongation and spontaneous hypertrophy of the inner labia, we illustrate and discuss the main biological factors that may trigger this medical condition. There are not enough data identifying a clear inheritance of inner labia hypertrophy in the absence of other pathological conditions; instead, we found indirect evidence for an association with transient episodes of local inflammation either before birth or during puberty. We also analyze the role played by estrogen receptors and other factors with regard to the onset of this condition and highlight the importance of their timing in determining the size of women's labia minora. Remarkably, most cases of enlarged labia minora should be considered as outliers that are within the physiological range of size variation described for these structures. CONCLUSIONS: We generally advise against surgical treatment of labia minora, especially in young, pre-pubertal girls, unless specific medical conditions are also present and/or the psychological impact on the patient is deemed particularly negative.

National Practice Patterns and Overall Survival After Adjuvant Radiotherapy Following Radical Cystectomy for Urothelial Bladder Cancer in the USA, 2004-2013.

BACKGROUND: Adjuvant radiation therapy (ART) after radical cystectomy (RC) for urothelial bladder cancer (UBC) may play a role in the management of muscle-invasive BC, particularly in patients with locally advanced disease and adverse pathologic features (pT3/4 or positive surgical margins [PSMs]). Evidence regarding the effect of ART on overall survival (OS) is lacking. OBJECTIVE: To evaluate national practice patterns for the use of ART and assess its impact on OS for patients with adverse pathologic features (APF) after RC. DESIGN, SETTING, AND PARTICIPANTS: Using the National Cancer Data Base, we analyzed all UBC cases with APF after RC from 2004 to 2013. Patients were divided into ART and no-ART groups. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Relationships with oncological outcomes were analyzed using multivariable Cox regression and log-rank analyses. RESULTS AND LIMITATIONS: Use of ART decreased during the study period from 3.1% in 2004 to 1.7% in 2013 (p=0.03). ART was administered in 1.4%, 4.0% and 5.2% of patients with pT3 UBC, pT4 UBC, and PSMs (any pT stage), respectively. The rate of ART was significantly higher among younger ages, female sex, low-volume hospitals, nonacademic community care centers, higher stages, PSMs, perioperative chemotherapy, and lymph node-positive disease. Predictors of ART receipt were PSMs (odds ratio [OR] 3.4; p<0.0001), pT4 (OR 2.6; p=0.02), community based centers (OR 2.1; p<0.0001), and female sex (OR 1.8; p<0.0001). Risk factors for worse OS included age, higher tumor stage and comorbidities, PSMs, positive nodes, and suboptimal lymph node dissection (<10 nodes removed; all p<0.001). ART was not independently associated with better OS in the full cohort (p=0.54). However, subgroup analyses suggested an OS benefit for patients with PSMs (hazard ratio 0.73; p=0.047). Limitations include the retrospective design and limited details regarding cancer-specific survival. CONCLUSIONS: Use of ART for APF following RC is not common in the USA and the rate of ART has been decreasing over time. ART may have an OS benefit after RC for patients with PSMs. PATIENT SUMMARY: In this report we looked at the outcomes for patients with locally advanced bladder cancer receiving adjuvant radiation therapy following cystectomy in a large US population. We found that adding radiation therapy after removing the bladder cancer may have some survival benefits for patients with positive surgical margins.

Uterine artery Doppler ultrasound in second pregnancy with previous elective cesarean section.

OBJECTIVES: To assess the effects of previous cesarean delivery (CD) and placental location on second trimester uterine artery Doppler indices in subsequent pregnancy and to assess the predictive values of abnormal Doppler findings for adverse pregnancy outcomes in women with previous CD. STUDY DESIGN: This prospective cohort study evaluated 400 gravida two pregnant women (200 with previous none medically indicated CD and 200 with previous normal vaginal deliveries (NVD)) who were referred for second trimester fetal anatomic survey. Uterine artery Doppler studies were performed in all participants who were then followed until delivery. RESULTS: Compared with women having prior NVD, women with prior CD had significantly higher rates of abnormal uterine artery pulsatility index (PI) (p < .001), and significantly more adverse pregnancy outcomes (p = .01). Among women with previous CD, all the measured adverse pregnancy outcomes occurred significantly more often in women with abnormal uterine artery Doppler indices (p < .001). CONCLUSIONS: CD seems to be associated with increased risks of impaired placental function and circulation and adverse pregnancy outcomes in the subsequent pregnancy, particularly in women with anteriorly located placenta near the previous uterine scar.

Health Care Disparity and Pregnancy-Related Mortality in the United States, 2005-2014.

OBJECTIVE: To quantitate the contribution of various demographic factors to the U.S. maternal mortality ratio. METHODS: This was a retrospective observational study. We analyzed data from the Centers for Disease Control and Prevention (CDC) National Center for Health Statistics database and the Detailed Mortality Underlying Cause of Death database (CDC WONDER) from 2005 to 2014 that contains mortality and population counts for all U.S. counties. Bivariate correlations between the maternal mortality ratio and all maternal demographic, lifestyle, health, and medical service utilization characteristics were calculated. We performed a maximum likelihood factor analysis with varimax rotation retaining variables that were significant (P<.05) in the univariate analysis to deal with multicollinearity among the existing variables. RESULTS: The United States has experienced an increase in maternal mortality ratio since 2005 with rates increasing from 15 per 100,00 live births in 2005 to 21-22 per 100,000 live births in 2013 and 2014. (P<.001) This increase in mortality was most pronounced in non-Hispanic black women, with ratios rising from 39 to 49 per 100,000 live births. A significant correlation between state mortality ranking and the percentage of non-Hispanic black women in the delivery population was demonstrated. Cesarean deliveries, unintended births, unmarried status, percentage of deliveries to non-Hispanic black women, and four or fewer prenatal visits were significantly (P<.05) associated with the increased maternal mortality ratio. CONCLUSION: The current U.S. maternal mortality ratio is heavily influenced by a higher rate of death among non-Hispanic black or unmarried patients with unplanned pregnancies. Racial disparities in health care availability and access or utilization by underserved populations are important issues faced by states seeking to decrease maternal mortality.

Cyanotic congenital heart disease following fertility treatments in the United States from 2011 to 2014.

OBJECTIVE: To examine the risk for cyanotic congenital heart diseases (CCHDs) among live births in the USA, resulting from various forms of infertility treatments. METHODS: This study is a cross-sectional analysis of live births in the USA from 2011 to 2014. Infertility treatments are categorised into two of the following groups on birth certificates: assisted reproductive technology (ART) fertility treatment (surgical egg removal; eg, in vitro fertilisation and gamete intrafallopian transfer) and non-ART fertility treatment (eg, medical treatment and intrauterine insemination). We compared the risk for CCHD in ART and non-ART fertility treatment groups with those infants whose mothers received no documented fertility treatment and were naturally conceived (NC). RESULTS: Among 14 242 267 live births from 2011 to 2014, a total of 101 494 live births were in the ART and 81 242 resulted from non-ART fertility treatments. CCHD prevalence in ART, non-ART and NC groups were 393/100 892 (0.39%), 210/80 884 (0.26%) and 10 749/14 020 749 (0.08%), respectively. As compared with naturally conceiving infants, risk for CCHD was significantly higher among infants born in ART (adjusted relative risk (aRR) 2.4, 95% CI 2.1 to 2.7) and non-ART fertility treatment groups (aRR 1.9, 95% CI 1.6 to 2.2). Absolute risk increase in CCHD due to ART and non-ART treatments were 0.03% and 0.02%, respectively. A similar pattern was observed when the analysis was restricted to twins, newborns with birth weights under 1500 g and gestational age of less than 32 weeks. CONCLUSIONS: Our findings suggest an increased risk for CCHD in infants conceived after all types of infertility treatment.

Fetoscopic Open Neural Tube Defect Repair: Development and Refinement of a Two-Port, Carbon Dioxide Insufflation Technique.

OBJECTIVE: To describe development of a two-port fetoscopic technique for spina bifida repair in the exteriorized, carbon dioxide-filled uterus and report early results of two cohorts of patients: the first 15 treated with an iterative technique and the latter 13 with a standardized technique. METHODS: This was a retrospective cohort study (2014-2016). All patients met Management of Myelomeningocele Study selection criteria. The intraoperative approach was iterative in the first 15 patients and was then standardized. Obstetric, maternal, fetal, and early neonatal outcomes were compared. Standard parametric and nonparametric tests were used as appropriate. RESULTS: Data for 28 patients (22 endoscopic only, four hybrid, two abandoned) are reported, but only those with a complete fetoscopic repair were analyzed (iterative technique [n=10] compared with standardized technique [n=12]). Maternal demographics and gestational age (median [range]) at fetal surgery (25.4 [22.9-25.9] compared with 24.8 [24-25.6] weeks) were similar, but delivery occurred at 35.9 (26-39) weeks of gestation with the iterative technique compared with 39 (35.9-40) weeks of gestation with the standardized technique (P<.01). Duration of surgery (267 [107-434] compared with 246 [206-333] minutes), complication rates, preterm prelabor rupture of membranes rates (4/12 [33%] compared with 1/10 [10%]), and vaginal delivery rates (5/12 [42%] compared with 6/10 [60%]) were not statistically different in the iterative and standardized techniques, respectively. In 6 of 12 (50%) compared with 1 of 10 (10%), respectively (P=.07), there was leakage of cerebrospinal fluid from the repair site at birth. Management of Myelomeningocele Study criteria for hydrocephalus-death at discharge were met in 9 of 12 (75%) and 3 of 10 (30%), respectively, and 7 of 12 (58%) compared with 2 of 10 (20%) have been treated for hydrocephalus to date. These latter differences were not statistically significant. CONCLUSION: Fetoscopic open neural tube defect repair does not appear to increase maternal-fetal complications as compared with repair by hysterotomy, allows for vaginal delivery, and may reduce long-term maternal risks.

Health Care Disparity and State-Specific Pregnancy-Related Mortality in the United States, 2005-2014.

OBJECTIVE: To investigate factors associated with differential state maternal mortality ratios and to quantitate the contribution of various demographic factors to such variation. METHODS: In a population-level analysis study, we analyzed data from the Centers for Disease Control and Prevention National Center for Health Statistics database and the Detailed Mortality Underlying Cause of Death database (CDC WONDER) that contains mortality and population counts for all U.S. counties. Bivariate correlations between maternal mortality ratio and all maternal demographic, lifestyle, health, and medical service utilization characteristics were calculated. We performed a maximum likelihood factor analysis with varimax rotation retaining variables that were significant (P<.05) in the univariate analysis to deal with multicollinearity among the existing variables. RESULTS: The United States has experienced a continued increase in maternal mortality ratio since 2007 with rates of 21-22 per 100,000 live births in 2013 and 2014. This increase in mortality was most dramatic in non-Hispanic black women. There was a significant correlation between state mortality ranking and the percentage of non-Hispanic black women in the delivery population. Cesarean deliveries, unintended births, unmarried status, percentage of non-Hispanic black deliveries, and four or less prenatal visits were significantly (P<.05) associated with increased maternal mortality ratio. CONCLUSION: Interstate differences in maternal mortality ratios largely reflect a different proportion of non-Hispanic black or unmarried patients with unplanned pregnancies. Racial disparities in health care availability, access, or utilization by underserved populations are an important issue faced by states in seeking to decrease maternal mortality.

Twin anemia polycythemia sequence: a single center experience and literature review.

Twin anemia polycythemia sequence (TAPS) is defined by significant intertwin hemoglobin discordance without the amniotic fluid discordance that characterizes twin-twin-transfusion syndrome (TTTS) in monochorionic twin pregnancies. TAPS is an uncommon condition which can either occur spontaneously, or following fetoscopic laser ablation for TTTS. This complication is thought to result from chronic transfusion through very small placental anastomoses; however, the pathogenesis of TAPS remains unknown. Consequently, there is no consensus in the management of TAPS. In this article, three cases of TAPS are described and we review the literature on this uncommon pregnancy complication.

Trends in the delivery route of twin pregnancies in the United States, 2006-2013.

OBJECTIVES: To determine the trends of cesarean delivery rate among twin pregnancies from 2006 to 2013. STUDY DESIGN: This is a population-based, cross-sectional analysis of twin live births from United State birth data files of the National Center for Health Statistics for calendar years 2006 through 2013. We stratified the population based on the gestational age groups, maternal race/ethnicity, advanced maternal age (AMA) which was defined by age more than 35 years and within the standard birth weight groups (group 1: birth weight 500-1499g, group 2: birth weight 1500-2499g and group 3: birth weight >2500g). We also analyzed the effect of different risk factors for cesarean delivery in twins. RESULTS: There were 1,079,102 infants born of twin gestations in the U.S. from 2006 to 2013, representing a small but significant increase in the proportion of twin births among all births (3.2% in 2006 versus 3.4% in 2013). The rate of cesarean delivery in twin live births peaked at 75.3% in 2009, and was significantly lower (74.8%) in 2013. The rate of the twin live birth with the breech presentation increased steadily from 26.3% in 2006 to 29.1% in 2013. For the fetus of the twin pregnancy presented as breech, the cesarean delivery rate peaked at 92.2% in 2010, falling slightly but significantly in the ensuing 3 years. The results demonstrated that the decrease in cesarean delivery rate was due to fewer cesareans in non-Hispanic white patients; all other ethnic subgroups showed increasing rates of cesarean delivery throughout the study. Gestational diabetes, gestational hypertension, previous cesarean delivery and breech presentation were all significant risk factors for cesarean delivery during the entire study period. Induction of labor and premature rupture of the membranes were associated with lower rates of cesarean delivery in twins. CONCLUSION: The recent decrease in the cesarean delivery rate in twin gestation appears to be largely attributable to a decline in cesarean among pregnancies complicated by breech presentation in non-Hispanic white women, and may reflect a health care disparity that deserves further research.
