Placental abruption is a condition that should be carefully considered in perinatal management because it is associated with serious events in both the mother and neonate, such as intrauterine fetal death, cerebral palsy, obstetric critical bleeding, and uncontrollable bleeding. The concomitant presence of disseminated intravascular coagulation (DIC) more easily causes critical bleeding that may necessitate hysterectomy or multi-organ failure resulting in maternal death. Therefore, early management should be provided to prevent progression to serious conditions by performing both hemostatic procedures and DIC treatment. To take measures to improve the outcomes in both the mother and neonate, health guidance for pregnant women, early diagnosis, early treatment, development of the emergency care system, and provision of a system for transport to higher-level medical institutions should be implemented.

The causal relationship between cigarette smoking during pregnancy and adverse maternal and child health outcomes, such as preterm birth, low birth weight, and sudden infant death syndrome are well known. In addition, cigarette compounds are neurotoxic even at extremely low levels. Thirdhand smoke (THS) is the contamination that persists after secondhand tobacco smoke has been emitted into air. It refers to the tobacco-related gases and particles that become embedded in materials such as carpets, walls, furniture, blankets, and toys. THS is not strictly smoke but chemicals that adhere to surfaces from which they can be released back into the air, undergo chemical transformations, and/or accumulate. The concept of THS is a relatively new phenomenon in the environmental and public health field. Currently, the hazards of THS are not as well documented as the hazards of secondhand smoke. Furthermore, its health effects and biological effects are largely unknown. This review summarizes recent research progress in reproductive toxicology studies that use animal models and in vitro systems, studies of environmental contamination by THS, human exposure studies, and priorities for further research. Future research must be conducted to facilitate hazard identification, and exposure and risk assessment to address its health effect on susceptible populations, such as pregnant women and children. In addition, policies and laws concerning tobacco smoke will need to be reviewed and possibly revised with the role of THS considered as an indispensable component of a broader tobacco control strategy in maternal and child health.

Since the year 2000, low birth rates have resulted in significant decreases to maternity care services throughout many Korean hospitals. However, there has been a concomitant increase in the number of high-risk pregnancies, due to growing trends in delayed marriages and subsequent pregnancies. Increased maternal age is a risk factor associated with complicated pregnancies and high-risk deliveries, both of which are strongly related to maternal death. With this in mind, the Ministry of Health and Welfare has supported the establishment of a regional perinatal center for high-risk pregnancies, estimated to be be fully completed by the year 2020. Despite this, maternity care services for high-risk pregnancies remain insufficient. According to previous reports, the total number of maternity care hospitals and beds available for high-risk pregnant women were 60 and 399, respectively. This is in stark contrast to previous bed estimates of 1,640. The establishment of a maternity care system for high-risk pregnant women is integral to ensuring optimal conditions for both pregnancy and childbirth. This review briefly evaluates the existing maternity care system for high-risk pregnancies, and proposes several new suggestions for improvements.

The number of women with congenital heart disease (CHD) at risk of pregnancy is growing because over 90% of them are grown-up into adulthood. The outcome of pregnancy and delivery is favorable in most of them provided that functional class and systemic ventricular function are good. Women with CHD such as pulmonary hypertension (Eisenmenger syndrome), severe left ventricular outflow stenosis, cyanotic CHD, aortopathy, Fontan procedure and systemic right ventricle (complete transposition of the great arteries [TGA] after atrial switch, congenitally corrected TGA) carry a high-risk. Most frequent complications during pregnancy and delivery are heart failure, arrhythmias, bleeding or thrombosis, and rarely maternal death. Complications of fetus are prematurity, low birth weight, abortion, and stillbirth. Risk stratification of pregnancy and delivery relates to functional status of the patient and is lesion specific. Medication during pregnancy and post-delivery (breast feeding) is a big concern. Especially prescribing medication with teratogenicity should be avoidable. Adequate care during pregnancy, delivery, and the postpartum period requires a multidisciplinary team approach with cardiologists, obstetricians, anesthesiologists, neonatologists, nurses and other related disciplines. Caring for a baby is an important issue due to temporarily pregnancy-induced cardiac dysfunction, and therefore familial support is mandatory especially during peripartum and after delivery. Timely pre-pregnancy counseling should be offered to all women with CHD to prevent avoidable pregnancy-related risks. Successful pregnancy is feasible for most women with CHD at relatively low risk when appropriate counseling and optimal care are provided.

OBJECTIVE: Reviewing indications and characteristics of obstetric patients admitted to the intensive care unit (ICU) of a tertiary care center, comparing those patients by time period and place of delivery, and to verify clinical utility of acute physiology and chronic health evaluation (APACHE) II score in ICU-admitted women. METHODS: Retrospective analyses were carried out for parturients admitted to the ICU of our institution from 1994 to 2015. Clinical characteristics were compared between time period (period 1: 1994–2004; period 2: 2005–2015) and place of delivery (our institution and local hospitals). Receiver operating characteristic (ROC) curve analysis was used to evaluate the usefulness of APACHE II score to predict maternal mortality. RESULTS: During 22-year period, 176 women required ICU admission, showing the incidence of 2.2 per 1,000 deliveries. The most common reason for ICU admission was postpartum hemorrhage (56.3%), followed by hypertensive disorders (19.3%), sepsis (3.4%), and pulmonary and amniotic fluid embolism (2.3%). Period 2 showed older maternal age (32.7±4.8 vs. 30.8±4.4 years, P=0.006, higher embolization rate (26.4% vs.1.2%, P < 0.001), and lower hysterectomy rate (30.8% vs. 49.4%, P=0.012). Cases from local hospitals showed significantly higher proportion of postpartum hemorrhage (84.5% vs. 42.2%, P < 0.001). Overall maternal death occurred in 5.1% (9/176) including 6 direct maternal deaths. The APACHE II score showed area under the ROC curve of 0.813 (confidence interval [CI], 0.607–1.000) for prediction of maternal mortality. CONCLUSION: The incidence of obstetric ICU admission was 2.2 per 1,000 deliveries and the most common reason was postpartum hemorrhage followed by hypertensive disorders. APACHE II score could be used to predict mortality in obstetric ICU admission.

This study aimed to analyze infant, maternal, perinatal, and fetal mortality statistics in the Republic of Korea (Korea), 2014. It was based on the open-access data available from the Statistics Korea website (http://kostat.go.kr/portal/eng/index.action). Recent trends in these vital statistics were also examined. The results of this study constitute a descriptive presentation and analysis of the national data. The number of infant deaths was 1,305 out of 435,435 live births in 2014, and the infant mortality rate was 3.0. The number of maternal deaths was 48. The maternal mortality ratio per 100,000 live births was 11.0. The maternal mortality ratio per 100,000 women of child-bearing age (15 to 49 years old) was 0.37. The number of perinatal deaths was 1,365, and the perinatal mortality rate was 3.1. The number of fetal deaths was 5,317. The fetal mortality rate was 12.1. The trends in those vital statistics in recent years were consistent except for a few findings, including a decrease in the maternal mortality ratio of pregnant women 40 years old and older and a change in the proportions of the causes of infant death, with a decrease in mortality due to neonatal respiratory distress and an increase in mortality due to bacterial sepsis. Although these vital statistics were generally consistent, some aspects varied by year. Pregnant women less than 20 years old should be monitored more intensively for their babies' health. Our findings can serve as basic data supporting the establishment of health policies by the Korean government.

OBJECTIVES: Cesarean section is associated with an increased risk for venous thromboembolism (VTE). The safety and efficacy of primary prophylaxis of fondaparinux, a synthetic sulfated pentasaccharide heparin analog, in women at risk after cesarean section is uncertain. METHODS: This was a retrospective study of 295 cases of pregnant women presenting to a tertiary referral center of Nara, Japan, to evaluate the usefulness of thromboprophylaxis with fondaparinux after cesarean delivery between 2011 and 2012. Patients were initially received unfractionated heparin (once 5,000 IU subcutaneously, twice a day), starting 6 hours after cesarean section for 24 hours, and then treated with fondaparinux (once 2.5 mg daily, subcutaneously) for 5 days. The primary efficacy end-point was an improvement in the incidence of symptomatic VTE or fatal post-cesarean pulmonary thromboembolism. The primary safety end-point was major bleeding during treatment. RESULTS: There were neither any episodes of symptomatic VTE cases nor maternal deaths. A total of 10 patients had a bleeding event. Major bleeding complication was observed in 2 (0.68%) of 295 patients receiving fondaparinux. Non-major bleeding into critical sites was observed in 8 patients, often at surgical sites, and recovery was not delayed. CONCLUSION: This study demonstrates the safety and efficacy of fondaparinux in women at high risk of VTE after cesarean section. Large phase trials comparing clinical outcomes with fondaparinux across a wide spectrum of patients are needed to confirm these observations.

The relationship between social disparity and specific causes of infant mortality has rarely been studied. The present study analyzed infant mortality trends according to the causes of death and the inequalities in specific causes of infant mortality between different parental social classes. We analyzed 8,209,836 births from the Statistics Korea between 1995 and 2009. The trends of disparity for cause-specific infant mortality according to parental education and employment were examined using the Cox proportional hazard model for the birth-year intervals of 1995–1999, 2000–2004, and 2005–2009. Adjusted hazard ratios were calculated after adjusting for infants' gender, parents' age, maternal obstetrical history, gestational age, and birth weight. An increasing trend in social inequalities in all-cause infant mortality according to paternal education was evident. Social inequalities in infant mortality were greater for “Not classified symptoms, signs and findings” (International Classification of Diseases 10th revision [ICD-10]: R00–R99) and “Injury, poisoning and of external causes” (S00–T98), particularly for “Ill-defined and unspecified causes” (R990) and “Sudden infant death syndrome (SIDS)” (R950); and increased overtime for “Not classified symptoms, signs and findings” (R00–R99), “Injury, poisoning and of external causes” (S00–T98) and “Conditions in perinatal period” (P00–P96), particularly for “SIDS” (R950) and “Respiratory distress syndrome of newborns (RDS)” (P220). The specific causes of infant mortality, in particular the “Not classified causes” (R00–R99 coded deaths) should be investigated more thoroughly to reduce inequality in health.

Acute fatty liver of pregnancy (AFLP) is one of the sudden unexpected causes in pregnancy and maternal deaths. It has been considered as a potential fatal disease in pregnancy, but the postmortem findings of AFLP is not well known. Because an unexpected maternal death may lead to a legal dispute, forensic pathologists should be aware of clinical presentations and postmortem findings of AFLP. Therefore, we presented our case and reviewed with literatures.

BACKGROUND: Severe or massive postpartum hemorrhage (PPH) has remained a leading cause of maternal mortality for decades across the world and it results in critical obstetric complications. Recombinant activated factor VII (rFVIIa) has emerged as a gold standard adjunctive hemostatic agent for the treatment of life-threatening PPH refractory to conventional therapies although it remains off-licensed for use in PPH. We studied the effects of rFVIIa on coagulopathy, transfusion volume, prognosis, severity change in Korean PPH patients. METHODS: A retrospective review of medical records between December 2008 and March 2011 indicating use of rFVIIa in severe PPH was performed. We compared age, rFVIIa treatment, transfusion volume, and Sequential Organ Failure Assessment (SOFA) score at the time of arrival in the emergency department and after 24 hours for patients whose SOFA score was 8 points or higher. RESULTS: Fifteen women with SOFA score of 8 and above participated in this study and eight received rFVIIa administration whereas seven did not. Patients' mean age was 31.7 ± 7.5 years. There was no statistically significant difference in initial and post-24 hours SOFA scores between patients administered rFVIIa or not. The change in SOFA score between initial presentation and after 24 hours was significantly reduced after rFVIIa administration (P = 0.016). CONCLUSIONS: This analysis aimed to support that the administration of rFVIIa can reduce the severity of life-threatening PPH in patients. A rapid decision regarding the administration of rFVIIa is needed for a more favorable outcome in severe PPH patients for whom there is no effective standard treatment.
