INTRODUCTION: The objective was to assess obstetrical complications and neonatal outcomes in women with endometriosis as compared to women without endometriosis. MATERIAL AND METHODS: National cohort including all delivering women and their newborns in Denmark 1997-2014. Data were extracted from the Danish Health Register and the Medical Birth Register. Logistic regression analysis provided odds ratios (OR) with 95% confidence intervals (CI). Sub-analyses were made for primiparous women with a singleton pregnancy and for women with endometriosis who underwent gynecological surgery before pregnancy...

OBJECTIVE: To estimate the risk of placenta-mediated complications in women in their third delivery according to their obstetric history in the first and second deliveries. METHODS: A retrospective cohort study of all women with singleton pregnancies who delivered their first three consecutive deliveries in a single medical center over a 20-year period (1994-2013). The risk of placenta-mediated complications in the third delivery, that is, hypertensive disorders such as preeclampsia or gestational hypertension, placental abruption, and small for gestational age (SGA less than the 10th percentile), was assessed according to the presence or absence of complications in previous deliveries...

OBJECTIVE: We hypothesized that the origins of abruption may extend to the stages of placental implantation; however, there are no reliable markers to predict its development. Based on this hypothesis, we sought to evaluate whether first-trimester and second-trimester serum analytes predict placental abruption. METHODS: We performed a secondary analysis of data of 35,307 women (250 abruption cases) enrolled in the First and Second Trimester Evaluation of Risk cohort (1999-2003), a multicenter, prospective cohort study...

AIM: A cohort study was performed to clarify the influence of risk factors on perinatal events (obstetric complications and/or perinatal deaths). METHODS: This cohort study reviewed 395 785 births from 2011 to 2013. Women with singleton pregnancies delivered after 22 weeks of gestation were included. The OR were determined on multivariate analysis. The perinatal event score (PES) for risk factors, which is the product of the OR of risk factors for obstetric complications, OR of risk factors for perinatal death, and OR of obstetric complications for perinatal death, was introduced to clarify the impact of each risk combination...

Objective. To determine circadian variation in the onset of placental abruption. Methods. A retrospective study involving 115 placental abruptions, divided into four subgroups based on initial symptoms comprising abdominal pain, vaginal bleeding, both abdominal pain and bleeding, or other symptoms. The time of the initial symptom was considered the disease onset. We analyzed the frequency of disease onset and adverse perinatal outcome including perinatal death relative to the daily four 6-hour intervals. Results...

Radiologic studies indicate that placental calcifications seen at 28-32 weeks' gestation are associated with adverse fetal outcome. One type of placental calcification is typically located at the basement membrane of chorionic villi. It has a fine particulate appearance and can only be seen microscopically. We have designated these calcifications as Intravillous and Intrafibrinous Particulate MicroCalcification (IPMC). In this study we examined the distribution and potential significance of IPMC. Placentas from 14 groups of fetal and maternal outcomes are examined histologically for IPMC...

The risk of pregnancy loss in von Willebrand disease (VWD) has been inconsistently reported. Von Willebrand factor (VWF) is a known regulator of angiogenesis, so has the potential to affect placental function. We sought to determine the risk of pregnancy loss and placenta-mediated pregnancy complications in women with VWD, compared with women without VWD. Women with VWD followed in the Southern Alberta Rare Blood and Bleeding Disorders Clinic were invited to participate in a questionnaire (February-June 2014)...

PURPOSE OF REVIEW: Although most fetal disorders can be treated after birth, a few conditions that predictably lead to fetal or neonatal death, or that progress significantly before birth, are ideally treated prenatally. The number of centers offering fetal therapeutic procedures is gradually increasing worldwide. Patients and caregivers should be aware of the potential maternal risks of these interventions. RECENT FINDINGS: For transplacental medical therapy (corticosteroids, antiarrhythmics and immunoglobulins), severe maternal adverse events are rare, when done in expert centers...

Pregnancy characteristics are associated with risk of cardiovascular diseases, but their independent associations with hypertension or blood pressure (BP) levels remain uncertain. We linked the Swedish Medical Birth Register with Västerbotten Intervention Program data (Northern Sweden). Using linear and logistic regression, we related pregnancy factors in any prior pregnancy with BP and hypertension at 40 years of age in 15 896 parous women free of prepregnancy hypertension. Pregnancy factors included parity, age at first delivery, preeclampsia, gestational diabetes mellitus, placental abruption, shortest gestational age small for gestational age baby (<third percentile for birth weight) or stillbirth...

AIM: To determine risk factors for severe complications during and after cesarean delivery (CD) in placenta previa (PP). METHODS: We reviewed retrospectively collected data from women with PP who underwent CD during a 6-year study period. We identified the complicated group based on the modified World Health Organization near-miss criteria. Complicated and non-complicated groups were compared considering clinical, laboratory, and sonographic features. RESULTS: Thirty-seven of 256 cases classified as near miss consisting of 14 peripartum hysterectomies, 12 uterine balloon placements, 10 great artery ligations, and 4 B-lynch suture placement procedures without maternal mortality...

BACKGROUND: Intraventricular hemorrhage is a major risk factor for neurodevelopmental disabilities in preterm infants. However, few studies have investigated how pregnancy complications responsible for preterm delivery are related to intraventricular hemorrhage. OBJECTIVE: To investigate the association between the main causes of preterm delivery and intraventricular hemorrhage in very preterm infants born in France during 2011 between 22 and 31 weeks of gestation...

Müllerian anomalies are defined as congenital uterine malformations that arise from improperly developing Müllerian ducts. These malformations have a variety of presentations ranging from asymptomatic to amenorrhea, dyspareunia, dysmenorrhea, chronic pelvic pain, pregnancy loss, fetal malpresentation, placental abruption, and intrauterine growth restriction. In this review, we discuss the clinical implications, diagnosis, and treatment of the various Müllerian anomalies focusing on the ones for which clinical intervention is amenable to improve pregnancy outcomes...

Chronic hypertension affects up to 5% of pregnancies. Women can be stratified into low-risk or high-risk chronic hypertension based on baseline laboratory and diagnostic work-up, comorbid conditions, and outcomes in prior pregnancies. Pregnancies complicated by chronic hypertension are at risk for increased adverse maternal and neonatal outcomes including superimposed preeclampsia, fetal growth restriction, placental abruption, and perinatal death. Mainstays of management include blood pressure control, close monitoring for development of superimposed preeclampsia, serial ultrasound assessment of fetal growth, and antenatal testing after 32 weeks...

PURPOSE: The aim of this study was to assess relationship between exposure to particulate matter (PM) chemicals during pregnancy and the odd of having placental abruption. METHODS: The 2004 to 2007 Florida linked birth certificate records and the Environmental Protection Agency PM speciation data were used. We were interested in placental abruption. We computed adjusted odds ratios (ORs) and 95% confidence intervals (95% CIs). RESULTS: The odds for placental abruption were increased per interquartile range (IQR) increase in aluminum during the first trimester (OR = 1...

Background Hemoperitoneum is a life-threatening surgical emergency. Diagnosis of the cause is often difficult, in particular, during pregnancy when it may be either obstetric or nonobstetric. Case We report the case of a hemoperitoneum caused by the backflow of blood through a uterine tube, due to placental abruption. Conclusion Hemoperitoneum in pregnant women with no other signs can reveal placental abruption. The difficulty in identifying the cause may delay appropriate management.

Thyroid dysfunctions such as hypothyroidism, thyrotoxicosis and thyroid nodules may develop during pregnancy leading to abortion, placental abruptions, preeclampsia, preterm delivery and reduced intellectual function in the offspring. Epidemiological data have shown the significant role of maternal thyroid hormone in fetal neurologic development and maternal health. It has been suggested that the deleterious effects of thyroid dysfunction can also extend beyond pregnancy and delivery to affect neuro-intellectual development in the early life of the child...

BACKGROUND: Placental abruption is an emergency obstetric complication. Although the etiology of abruption is not fully understood, acute stimuli, such as ischemia and/or inflammation, are associated with rupture of the decidual artery, resulting in placental separation. Ischemia and inflammation are acute biologic effects of air pollution. Using a case-crossover design, we tested the hypothesis that a short-term increase in exposure to air pollutants is a potential trigger of placental abruption...
