Abstract
OBJECTIVE The purpose of this review is to ascertain the indications, techniques, and the associated morbidity with the use of Bakri balloon. MATERIAL AND METHODS A literature search using the PubMed database was conducted from 2001 to 2013. We calculated 95% confidence intervals (CIs) for complications. RESULTS We identified 12 publications that met the inclusion criteria. Four reports provided the frequency of Bakri use during the study period, with the overall rate being 0.20% (138/69, 174; 95% CI, 0.17-0.25%). Two-thirds of use followed cesarean delivery (67%; 182/273). Uterine atony was specified as the underlying etiology of postpartum hemorrhage in 75% (9/12) of publication. The rate of balloon displacement was 10% (95% CI, 6-16%) and need for transfusion, 43% (95% CI, 32-55%). Hysterectomy was undertaken in 6% (95% CI, 4-10%). CONCLUSIONS There is a paucity of publications on Bakri balloon. Before its utilization is recommended in guidelines, a randomized clinical trial comparing uterotonics alone versus with balloon is warranted.

Abstract
BACKGROUND There has been very limited documentation of the adverse maternal and/or fetal consequences of airbag deployment in association with motor vehicle accidents. CASE A 20-year-old woman, gravida 1, para 0, at 31+ 4 weeks' gestation, was involved in a motor vehicle accident. The car had been hit from the passenger side at an estimated speed of 45 miles per hour. The vehicle was noted to have rolled over, along with deployment of the driver's side and passenger's airbags. Via star low transverse cesarean, the patient was delivered of a very pale-appearing, 1,890g infant with Apgars of 1 and 7 at 1 and 5 minutes of life, respectively. There was an approximate 50% abruption noted on placental evaluation, as well as a 2 x 3-cm area ofecchymosis at the uterinefundus. The neonate's immediate postdelivery hematocrit was 17%. A cranial ultrasound was notable for a grade III germinal matrix hemorrhage with progressive hydrocephalus. Serial ultrasounds showed interval increases in the amount of clots within the lateral ventricles. CONCLUSION Airbag deployment can be associated with placental abruption and fetal intracranial hemorrhage.

Abstract
BACKGROUND/AIMS To examine the relationship of the amniotic fluid index (AFI) and single deepest pocket (SDP) with an AFV as modelled by Brace or Magann. METHODS AFI and SDP were evaluated for their correlation with an actual AFV using the Spearman correlation coefficient. RESULTS 482 AFI and 468 SDP pregnancies were evaluated. There was a significant association between the AFI and SDP and an actual AFV (p < 0.0001). The AFI range of 5.1-20 was better correlated than 5.1-24 for normal AFVs Brace (κ = 0.175) and Magann (κ = 0.356) versus 5.1-24 (κ = 0.150 and κ = 0.319), respectively. The agreement level t for the AFI (κ = 0.175) and SDP (κ = 0.126) using Brace was slight and for the AFI (κ = 0.356) and SDP (κ = 0.295) using Magann was fair. CONCLUSIONS Both the AFI and SDP were correlated with actual AFV using both models. AFI of 5.1-20 better categorizes normal volumes. Although the Magann model correlates AFI/SDP and AFV better, the superiority is minimal.

Abstract
Though subjective in nature, both the American College of Obstetricians and Gynecologists practice bulletin and the Royal College of Obstetricians and Gynaecologists green guideline are in agreement on the descriptor of shoulder dystocia: requirement of additional obstetric maneuvers when gentle downward traction has failed to affect the delivery of the shoulders. The rate of shoulder dystocia is about 1.4% of all deliveries and 0.7% for vaginal births. Compared to non-diabetics (0.6%), among diabetics, the rate of impacted shoulders is 201% higher (1.9%); newborns delivered by vacuum or forceps have 254% higher likelihood of shoulder dystocia than those born spontaneously (2.0% vs. 0.6%, respectively). When the birthweight is categorized as <4000, 4000-4449, and >4500 g, the likelihood of shoulder dystocia in the US vs. other countries varies significantly. Future studies should focus on lowering the rate of shoulder dystocia and its associated morbidities, without concomitantly increasing the rate of cesarean delivery.

Abstract
Epidemiological knowledge of the incidence, prevalence, and temporal changes of neonatal brachial plexuses palsy (NBPP) should assist the clinician, avert unnecessary interventions, and help formulate evidence-based health policies. A summary of 63 publications in the English language with over 17 million births and 24,000 NBPPs is notable for six things. First, the rate of NBPP in the US and other countries is comparable: 1.5 vs. 1.3 per 1000 total births, respectively. Second, the rate of NBPP may be decreasing: 0.9, 1.0 and 0.5 per 1,000 births for publications before 1990, 1990-2000, and after 2000, respectively. Third, the likelihood of not having concomitant shoulder dystocia with NBPP was 76% overall, though it varied by whether the publication was from the US (78%) vs. other countries (47%). Fourth, the likelihood of NBPP being permanent (lasting at least 12 months) was 10-18% in the US-based reports and 19-23% in other countries. Fifth, in studies from the US, the rate of permanent NBPP is 1.1-2.2 per 10,000 births and 2.9-3.7 per 10,000 births in other nations. Sixth, we estimate that approximately 5000 NBPPs occur every year in the US, of which over 580-1050 are permanent, and that since birth, 63,000 adults have been afflicted with persistent paresis of their brachial plexus. The exceedingly infrequent nature of permanent NBPP necessitates a multi-center study to improve our understanding of the antecedent factors and to abate the long-term sequela.

Abstract
The primary objective of this survey was to ascertain the opinions, practices and knowledge about exercise, including yoga, during pregnancy; the secondary objective to compare the responses among women with body mass index (BMI) <30 kg/m(2) versus ≥30 kg/m(2). Survey consisted of 20 multiple choice questions assessing demographics and exercise practices, and five questions testing their knowledge about it during pregnancy (ACOG Committee Opinion # 267). Of the 500 surveys distributed, 84% (422) responses were analyzed. While 86% of women responded that exercise during pregnancy is beneficial, 83% felt it was beneficial to start prior to pregnancy, and walking was considered the most beneficial (62%). The majority (64%) of respondents were currently exercising during pregnancy and 51% exercised 2-3 times/week. Among the five questions testing knowledge about prenatal exercise, majority (range 60 to 92%) were aware of ACOG recommendations. About half had a BMI ≥30. Knowledge about benefits of exercise during pregnancy did not differ significantly between obese and non-obese. Yoga was tried significantly more among non-obese, 65% believed it is beneficial, and 40% had attempted yoga before pregnancy. In our population, the majority believes that exercise, including yoga, is beneficial and they are active.

Abstract
The purposes of this review were to describe deliveries complicated by shoulder dystocia (SD) at three tertiary centers and discern the differences between SD with and without brachial plexus injury (BPI). The inclusion criteria for this multicenter, retrospective study were singletons, delivered vaginally with SD. To discern the risk factors for SD with and without injury, a case (SD and BPI) versus control (3 SD without injury at the same institution) design was used. Multiple linear regression was employed. Over a 7-year period, among 46,637 vaginal deliveries, SD occurred in 1,177 cases (2.5%) and BPI was noted in 11%. The results of multiple regression indicate that gestational age, operative delivery, and the number of maneuvers and concomitant fracture (4%) were statistically associated with BPI following SD (p < 0.001). SD was not associated with BPI in 89% and 88% of the cases that were resolved with McRoberts maneuver and suprapubic pressure, whereas only 0.2% of cases were litigated.

Abstract
We examined the rate of detecting small for gestational age (SGA; birth weight < 10%) as intrauterine growth restriction (IUGR) prenatally at four centers and determined risks of composite neonatal morbidity (CNM) and mortality among detected versus undetected (no antenatal diagnosis of IUGR). A multicenter cohort study of 11,487 nonanomalous, singleton live births with sonographic exam before 22 weeks was performed. Of 11,487 births, 8% (n = 929) were SGA that met the inclusion criteria, with 25% of them being prenatally detected. The CNM among SGA births that were prenatally detected as IUGR was higher (23.3%) than undetected SGA (9.7%), but this difference was no longer significant following adjustments for confounding factors. Among preterm births (< 37 weeks), undetected SGA had significantly higher CNM (risk ratio [RR] 10.0, 95% confidence interval [CI] 6.3, 16.1) for deliveries at 24 to 33 weeks and RR 3.0, 95% CI 1.7, 5.4 for 34 to 36 weeks). In summary, only a quarter of SGA births were detected prenatally as IUGR and among preterm SGA, the CNM is significantly higher when SGA births are undetected as IUGR.

Abstract
OBJECTIVES The aim of this pilot study was to measure the angle of rotation of the uterus at the fundus from horizontal using 3-dimensional sonography in women presenting for annual gynecologic examinations. METHODS A total of 51 patients participated in the study. All patients underwent transvaginal sonography, and 3-dimensional volumes were acquired. The cervicouterine angle and the angle of rotation at the fundus were measured. RESULTS The uteri were noted to be anteverted in 64.7%, retroverted in 25.5%, and euverted in 9.8%. They were noted to be pointing toward the right side of the pelvis in 49.0%, to the left side in 39.2%, and at the midline in 11.8%. The median cervicouterine angle was 122° (interquartile range [IQR], 105°-137°). The median angle of rotation at the fundus away from horizontal in either a clockwise or counterclockwise direction on the transverse B-plane was 10.4° (IQR, 7.1°-19.0°), with a maximal angle of 43°, and on the coronal C-plane, it was 10.0° (IQR, 3.0°-20.0°), with a maximal angle of 43°. Noneuverted uteri were more likely to be rotated at the fundus. CONCLUSIONS Our study reveals that, contrary to traditional thinking, the uterus can be rotated at the fundus in relation to the body (z-axis) along the longitudinal axis of the cervical canal.

Abstract
OBJECTIVE To determine factors associated with active duty military women being within Navy weight standards 6 months following childbirth. METHODS Inclusion criteria for this study were active duty women who delivered a nonanomalous fetus at a Naval Hospital and who remained in the area and their weight was recorded 6 months following childbirth. Multivariate logistic regressions, adjusted for 14 covariates, determined the factors for achieving acceptable weight. RESULTS Among 1,009 women who participated in this prospective cohort study, 68% began within Navy body weight standards and 52% had a normal body mass index (BMI) (<25). Six months after childbirth, 48% were within Navy body weight standards and 32% had a BMI <25. Only 2 factors, BMI at first visit and cesarean delivery, significantly influenced the percentage of women who met the weight standards at 6 months. CONCLUSIONS Lowering the prepregnancy BMI and avoiding a cesarean delivery may improve the percentage of active duty women who meet weight standards 6 months after childbirth.

Abstract
Confusion in terminology and non-standardized definitions can arguably be classified as the most important characteristics that lead to disparate study findings. While such situations abound in all of perinatal epidemiology, the study of "periviable birth" is a classic case in point. The most common term used to describe periviable birth has been extremely low birthweight (ELBW), often defined as newborns with birthweight below 1000g; yet, we identified 11 other descriptors for periviable birth. Due to the multitude of definitions, the reported incidence of periviable births varies from 0.03% to 1.9% (a relative difference of 7025%). Antecedent risk factors for periviable birth, though geographically heterogeneous, include nulliparity and multiple gestations, each accounting for one-third and one-fourth of all periviable births, respectively. Spontaneous preterm labor precedes 34% of these deliveries and premature rupture of membranes in 25%. The pregnancy was complicated by hypertensive disease in 21% and bleeding and chorioamnionitis in 18% each. Over 50% of these births are cesarean deliveries. Six clinical interventions before delivery that may improve outcomes include transfer of patient to a tertiary center, administration of antenatal corticosteroids, tocolytics, or antibiotics after premature rupture of membranes, assessment of fetal well-being with electronic fetal heart rate monitoring, and willingness to perform a cesarean delivery after the limit of viability is reached. While there is an accessible predictive model for mortality and long-term morbidities for newborns delivered at 22-25 weeks with weights of 400-1000g, it is hampered by the need to know the birthweight. In addition to reaching a consensus regarding what birthweight-gestational age thresholds determine a periviable birth, the acute need to optimize neonatal outcomes remains a paramount target worthy of future research, and efforts to advance obstetrical medicine are needed to minimize the likelihood of its occurrence.

Abstract
The objective of our systematic review was to provide updated evidence-based guidance for surgical decisions during cesarean delivery (CD). We performed an English-language MEDLINE, PubMed, and COCHRANE search with the terms, cesarean section, cesarean delivery, cesarean, pregnancy, and randomized trials, plus each technical aspect of CD. Randomized control trials (RCTs) involving any aspect of CD technique from Jan. 1, 2005, to Sept. 1, 2012, were evaluated to update a previous systematic review. We also summarized Cochrane reviews, systematic reviews, and metaanalyses if they included additional RCTs since this review. We identified 73 RCTs, 10 metaanalyses and/or systematic reviews, and 12 Cochrane reviews during this time frame. Recommendations with high levels of certainty as defined by the US Preventive Services Task Force favor pre-skin incision prophylactic antibiotics, cephalad-caudad blunt uterine extension, spontaneous placental removal, surgeon preference on uterine exteriorization, single-layer uterine closure when future fertility is undesired, and suture closure of the subcutaneous tissue when thickness is 2 cm or greater and do not favor manual cervical dilation, subcutaneous drains, or supplemental oxygen for the reduction of morbidity from infection. The technical aspect of CD with high-quality, evidence-based recommendations should be adopted. Although 73 RCTs over the past 8 years is encouraging, additional well-designed, adequately powered trials on the specific technical aspects of CD are warranted.

Abstract
OBJECTIVE We assessed the association among gestational age (GA) at birth, timing of death, and risk status of the pregnancy and racial/ethnic disparities in infant mortality rate in the United States. STUDY DESIGN We utilized U.S. 2000 to 2004 birth cohort-linked birth and infant death data restricted to nonanomalous singleton live births. Multivariable log-binomial regression models were fit to evaluate racial/ethnic disparities in infant mortality while adjusting for potential confounders. RESULTS Compared with whites, blacks had a higher adjusted infant mortality rate (IMR) (risk ratio [RR] 1.96, 95% confidence interval [CI] 1.91, 2.01), and Hispanics had a lower adjusted IMR (RR 0.79, 95% CI 0.76, 0.82). When categorized by GA, at 24 to 31 weeks, the adjusted early neonatal mortality (ENM) is significantly lower for black than whites, similar at 32 to 36 weeks, and at 37 weeks or more, blacks have significantly higher ENM. CONCLUSIONS The racial/ethnic disparities in infant mortality in the United States persist and vary across GA. These disparities may largely be driven by the excess post-neonatal deaths among blacks.

Abstract
Polyhydramnios is an excessive amount of amniotic fluid within the amniotic cavity. The etiology of polyhydramnios may be idiopathic, the consequence of fetal structural anomalies, or the consequence of various fetal and maternal conditions. The clinical importance of polyhydramnios is found in its association with adverse pregnancy outcomes and the risk of perinatal mortality. The antenatal management of polyhydramnios can be challenging as there are no formalized guidelines on the topic. The purpose of this review is to provide a literature-based overview on the subject of polyhydramnios in singleton pregnancies, demonstrate its clinical implications, and describe a practical approach to its management.

Abstract
OBJECTIVE We aimed to compare the rates of wound separation (WS) and surgical site infection (SSI) after cesarean delivery (CD) by a single surgeon. Pfannenstiel skin incision (PSI) was closed with Dermabond, staples, or suture. STUDY DESIGN Retrospectively all women having CD via PSI were identified. WS and SSI rates with Dermabond were compared with other two techniques. RESULTS Of 239 CDs performed, 88% (n = 211) were available for postpartum evaluation. The PSI was closed with Dermabond in 85 (40%), staples in 76 (36%), and suture in 50 (24%). Overall WS rate was 7%; with Dermabond, it was 5% versus 13% with staple (p = 0.090) and 2% with suture (p = 0.651). Post hoc calculation suggests a randomization of 4325 women is needed to determine if Dermabond has one-third less wound complication than suture. CONCLUSION For the PSI closure, Dermabond may be a useful alternative skin closure device, though a randomized trial is warranted.

Abstract
Beta2-adrenergic agonist medications such as albuterol and terbutaline are often prescribed during pregnancy to treat conditions such as asthma, pulmonary disease, preterm labor, or acute non-reassuring fetal heart rate abnormalities during labor. Recently a review article questioned the safety of beta2-adrenergic agonist use in pregnancy, postulating a "biologically plausible" link between the use of these agents and autism spectrum disorder in offspring of mothers exposed to these drugs. While it is imperative to determine any harmful effects of any medication during pregnancy, it is important to weigh the risks and known benefits of treatment versus nontreatment of conditions such as preterm labor with medications such as terbutaline, given the known rates of morbidity and mortality associated with prematurity. The purpose of our review and commentary is to explain how and why beta2-adrenergic agonists are used to treat preterm labor and to discuss the merits of the conclusions drawn by the Witter clinical commentary.
