Abstract
OBJECTIVE This study aims to compare neonatal and long-term outcomes among preterm newborns from women with reported versus those who did not report substance abuse. STUDY DESIGN Secondary analysis of a trial of magnesium sulfate for cerebral palsy prevention. Cases were pregnant women who reported substance abuse, controls were those who denied it. Study outcomes included (1) composite neonatal morbidity, defined as any of the following: Apgar score ≤ 3 at 5 minutes, seizures, culture-proven sepsis, necrotizing enterocolitis grades 2 or 3, intraventricular hemorrhage grades 3 or 4, and/or death before discharge; (2) infant and childhood morbidity, defined as stillbirth or death by 1 year, or moderate/severe cerebral palsy by age of 2. RESULTS Among 1,972 women meeting the inclusion criteria, 197 (10%) reported substance abuse. Composite neonatal, infant, and childhood morbidity rates were similar between cases and controls. However, women reporting substance abuse who delivered between 32(0/7) and 36(6/7) weeks had a higher frequency of composite infant and childhood morbidity (6.5 vs. 1.0%; adjusted odds ratio, 6.5; 95% confidence interval, 1.14-36.99). CONCLUSIONS Preterm birth was associated with similar composite neonatal morbidity between cases and controls. After 32 weeks, self-reported substance abuse was associated with a sevenfold increase in the rates of stillbirth and long-term infant morbidity.

Abstract
OBJECTIVE The objective of this study was to determine the morbidity of preterm small for gestational age (SGA) infants compared with appropriate for GA (AGA). STUDY DESIGN This is a secondary analysis of the randomized trial evaluating magnesium sulfate for the prevention of cerebral palsy (CP). We compared outcomes of preterm (< 37 weeks) nonanomalous infants who were SGA (birth weight < 10% for GA) versus AGA (birth weight 10-89% for GA). We compared (1) the parent trial primary outcome, a composite of stillbirth, infant death by 1 year of age, or moderate to severe CP at 2 years of age and (2) composite neonatal morbidity (CNM). RESULTS Of the 1,948 infants who met inclusion criteria, 95% were AGA and 5% were SGA. The primary outcome was similar (10 and 15%, p = 0.08), as was the CNM (24 and 25%, p = 0.89). Sample size calculations indicate that detection of a one-third higher rate of CNM among SGA compared with AGA infants requires more than 93,900 preterm births; for a one-third difference in moderate to severe CP, more than 1.4 million infants. CONCLUSION Owing to the prohibitive sample size required, ascertaining a difference in sequela between preterm SGA and AGA infants is possibly unverifiable.

Abstract
OBJECTIVE The purpose of this review was to determine the likelihood of malignancy or complications with ultrasonographic diagnosis of adnexal masses in pregnancy and to evaluate the obstetrical outcomes. Materials and METHODS A review of literature was performed using keywords "adnexal mass and pregnancy" or "ovarian mass and pregnancy." RESULTS Out of the 340 abstracts reviewed, 313 were excluded. The incidence of adnexal mass in pregnancy varied from 0.1 to 2.4%, with an average of 0.02%. Regarding the likelihood of malignancy, in seven publications, there were 557 women with 563 adnexal masses. Of these 563 masses, 48% were classified as simple and 52% as complex. Among the simple masses, 1% were malignant. Among the complex masses, 9% were malignant. When comparing laparoscopy and laparotomy, the rate of preterm contractions was found to be higher in patients undergoing laparotomy and this was statistically significant. Other measures, such as spontaneous abortion, vaginal bleeding, < 37 week delivery, and intrauterine fetal demise, were not found to have a significant difference. CONCLUSION Adnexal masses in pregnancy occur infrequently and depending on whether the surgery was performed emergently or electively, via laparoscopy or laparotomy, the outcomes will vary.

Abstract
OBJECTIVE The purpose of this study was to compare 4 national guidelines for the prevention and management of postpartum hemorrhage (PPH). STUDY DESIGN We performed a descriptive analysis of guidelines from the American College of Obstetrician and Gynecologists practice bulletin, the Royal Australian and New Zealand College of Obstetricians and Gynaecologists, the Royal College of Obstetrician and Gynaecologists (RCOG), and the Society of Obstetricians and Gynaecologists of Canada on PPH to determine differences, if any, with regard to definitions, risk factors, prevention, treatment, and resuscitation. RESULTS PPH was defined differently in all 4 guidelines. Risk factors that were emphasized in the guidelines conferred a high risk of catastrophic bleeding (eg, previous cesarean delivery and placenta previa). All organizations, except the American College of Obstetrician and Gynecologists, recommended active management of the third stage of labor for primary prevention of PPH in all vaginal deliveries. Oxytocin was recommended universally as the medication of choice for PPH prevention in vaginal deliveries. The Royal Australian and New Zealand College of Obstetricians and Gynaecologists and RCOG recommended development of a massive transfusion protocol to manage PPH resuscitation. Recommendations for nonsurgical treatment strategies such as uterine packing and balloon tamponade varied across all guidelines. All organizations recommended transfer to a tertiary care facility for suspicion of abnormal placentation. Specific indications for hysterectomy were not available in any guideline, with RCOG recommending hysterectomy "sooner rather than later" with the assistance of a second consultant. CONCLUSION Substantial variation exists in PPH prevention and management guidelines among 4 national organizations that highlights the need for better evidence and more consistent synthesis of the available evidence with regard to a leading cause of maternal death.

Abstract
OBJECTIVE This study aims to compare two management protocols in pregnancies diagnosed with fetal growth restriction (FGR). STUDY DESIGN All singleton pregnancies diagnosed and managed with FGR at our institution during two protocol periods were analyzed. The early term protocol (January 2008-February 2010) specified delivery at 37(0/7) weeks if antenatal testing was reassuring, but did not specify the timing of delivery if umbilical artery (UA) Doppler systolic:diastolic (S:D) ratios were elevated (>95th percentile for gestational age [GA]). The term protocol (March 2010-July 2012) specified delivery at 39(0/7) weeks with normal S:D ratios and 37(0/7) weeks with elevated S:D ratios when antenatal testing was reassuring. RESULTS There were 228 and 312 women in the early term and term protocol, respectively, who met inclusion criteria. Compared with the early term group, the term group had an increased median GA at delivery (37.1 vs. 38.6%, p < 0.001), decreased deliveries less than 37(0/7) weeks (37 vs. 24%, p = 0.01) and decreased neonatal intensive care unit (NICU) admissions (38 vs. 28%, p = 0.02). CONCLUSION A protocol specifying delivery at 39(0/7) weeks when UA S:D ratios are normal and delivery at 37(0/7) weeks when UA S:D ratios are elevated when other antenatal testing is reassuring in FGR: (1) prolonged gestation, (2) decreased preterm births, and (3) decreased NICU admissions.

Abstract
OBJECTIVE To compare the obstetric recommendations in American Congress of Obstetricians and Gynecologists (ACOG) practice bulletins (PB) with similar topics in UpToDate (UTD). STUDY DESIGN We accessed all obstetric PB and cross-searched UTD (May 1999-May 2013). We analyzed only the PB which had corresponding UTD chapter with graded recommendations (level A-C). To assess comparability of recommendations for each obstetric topic, two maternal-fetal medicine (MFM) subspecialists categorized the statement as similar, dissimilar, or incomparable. Simple and weighted kappa statistics were calculated to assess agreement between the two raters. RESULTS We identified 46 ACOG obstetric PB and 86 UTD chapters. There were 50% fewer recommendations in UTD than in PB (181 vs. 365). The recommendations being categorized as level A, B, or C was significantly different (p < 0.001) for the two guidelines. While the overall concordance rate between the two MFM subspecialists was 83% regarding the recommendations for the same topic as similar, dissimilar, or incomparable, the agreement was moderate (kappa, 0.56; 95% confidence intervals, 0.48-0.65). CONCLUSION Though obstetricians have two sources for graded recommendations, incongruity among them may be a source of consternation. Congruent recommendations from ACOG and UTD could enhance compliance and potentially optimize outcomes.

Abstract
OBJECTIVES Substance abuse in pregnancy remains a major public health problem. Fetal teratogenicity results from the effect of these substances during fetal development, particularly when used in combination. This review will focus on and attempt to clarify the existing literature regarding the association of substance abuse on the development of congenital anomalies and the long-term implications in exposed offspring. METHODS Systematic review of available English literature using the PubMed database of all peer-reviewed articles on the subject. RESULTS A total of 128 articles were included in this review. Alcohol was the most common substance associated with fetal anomalies, particularly facial dysmorphisms and alterations in the central nervous system development. Adverse maternal environments associated with risky behaviors and lack of adequate prenatal care precludes the timely detection of fetal anomalies, confounding most studies linking causality. In addition, although methodological differences and limited availability of well-designed trials exist, substance abuse in pregnancy has been associated with adverse long-term outcomes in infant growth, behavior, cognition, language and achievement. CONCLUSION The literature summarized in this review suggests that drug exposure during pregnancy may increase the risk of congenital anomalies and long-term adverse effects in exposed children and adolescents. These conclusions must be tempered by the many confounders associated with drug use. A multidisciplinary approach is paramount for appropriate counseling regarding the known immediate and long-term risks of substance abuse in pregnancy.

Abstract
Stercoral perforation of the colon, though rare, is associated with high mortality. Review of the literature identified only three prior cases reported during pregnancy. We report a case on a multiparous female presenting at 31 weeks of gestation with acute abdominal pain. Computed tomography suggested a sigmoid colon perforation. An urgent exploratory laparotomy was performed where feculent peritonitis and a stercoral perforation of the sigmoid colon was confirmed. A cesarean delivery and sigmoid colectomy with descending end colostomy was performed. While the newborn had an uncomplicated course, the mother developed an intra-abdominal abscess requiring operative management.

Abstract
OBJECTIVE Nonimmune hydrops is the presence of ≥2 abnormal fetal fluid collections in the absence of red cell alloimmunization. The most common etiologies include cardiovascular, chromosomal, and hematologic abnormalities, followed by structural fetal anomalies, complications of monochorionic twinning, infection, and placental abnormalities. We sought to provide evidence-based guidelines for the evaluation and management of nonimmune hydrops fetalis. METHODS A systematic literature review was performed using MEDLINE, PubMed, EMBASE, and Cochrane Library. The search was restricted to English-language articles published from 1966 through June 2014. Priority was given to articles reporting original research, although review articles and commentaries also were consulted. Abstracts of research presented at symposia and scientific conferences were not considered adequate for inclusion in this document. Evidence reports and guidelines published by organizations or institutions such as the National Institutes of Health, Agency for Health Research and Quality, American Congress of Obstetricians and Gynecologists, and Society for Maternal-Fetal Medicine were also reviewed, and additional studies were located by reviewing bibliographies of identified articles. Grading of Recommendations Assessment, Development, and Evaluation methodology was employed for defining strength of recommendations and rating quality of evidence. Consistent with US Preventive Task Force guidelines, references were evaluated for quality based on the highest level of evidence. RESULTS AND RECOMMENDATIONS Evaluation of hydrops begins with an antibody screen (indirect Coombs test) to determine if it is nonimmune, detailed sonography of the fetus(es) and placenta, including echocardiography and assessment for fetal arrhythmia, and middle cerebral artery Doppler evaluation for anemia, as well as fetal karyotype and/or chromosomal microarray analysis, regardless of whether a structural fetal anomaly is identified. Recommended treatment depends on the underlying etiology and gestational age; preterm delivery is recommended only for obstetric indications including development of mirror syndrome. Candidates for corticosteroids and antepartum surveillance include those with an idiopathic etiology, an etiology amenable to prenatal or postnatal treatment, and those in whom intervention is planned if fetal deterioration occurs. Such pregnancies should be delivered at a facility with the capability to stabilize and treat critically ill newborns. The prognosis depends on etiology, response to therapy if treatable, and the gestational age at detection and delivery. Aneuploidy confers a poor prognosis, and even in the absence of aneuploidy, neonatal survival is often <50%. Mirror syndrome is a form of severe preeclampsia that may develop in association with fetal hydrops and in most cases necessitates delivery.

Abstract
The evidence for a link between vitamin D and preeclampsia is conflicting. There is a paucity of studies reporting simultaneous 25-hydroxyvitamin D (inactive form) and 1,25-dihydroxyvitamin D (biologically active form). We investigated if levels of serum 25-hydroxyvitamin D, calcium-regulating hormones (1,25-dihydroxyvitamin D, parathyroid hormone), and calcium differ significantly between preeclamptics and controls. On postpartum day one, 98 subjects (44 with preeclampsia, 54 controls) were recruited among women admitted to the postdelivery unit, and their serum 25-hydroxyvitamin D, 1,25-dihydroxyvitamin D, parathyroid hormone, serum calcium, and serum albumin levels were prospectively measured. The majority of participants (70%) had serum 25-hydroxyvitamin D level<20 ng/mL; 53% had <15 ng/mL. Mean serum 25-hydroxyvitamin D level was similar between cases and controls (p=0.50). Mean total serum calcium adjusted for albumin and magnesium was similar between cases and controls (p=0.78). Mean serum 1,25-dihydroxyvitamin D and parathyroid hormone levels were normal, and there were no differences between cases and controls. The only significant differences found between preeclamptic cases and controls were mean body mass index, parity, and season of blood draw. Vitamin D levels did not differ among preeclamptic cases and controls.

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.

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.
