PURPOSE: Recently, the number of late preterm infants are increasing, and they are prone to have many clinical problems. The purpose of this study is to emphasize the importance of perinatal care for the late preterm infants and their mothers. METHODS: Total admitted numbers of late preterm infants were 547 (from 464 mothers) and of term infants were 1,514 (from 1,470 mothers) in NICU, at Chonnam National University Hospital January 2014~December 2015. Maternal and neonatal mortality rate were calculated in the total admitted numbers. Exclusion criteria were death or transfer during admission, congenital anomaly, and etc. The enrolled numbers of late preterm infants were 493 (from 418 mothers) and of term infants were 1,167 (from 1,123 mothers). Retrospective chart review was conducted. In mothers, demographics, underlying illness, and obstetric complication, and in newborns, demographics, hospital days and morbidity were compared between late preterm group and term group. RESULTS: Maternal mortality rate was not different. However, neonatal mortality rate was higher in late preterm infants. In mothers of late preterm group, there was no difference in demographic characteristics, but the rates of autoimmune disease and obstetric complication were higher. In infants of late preterm group, body size was smaller, artificial conception and C-section rate were higher, and one and five-minute Apgar scores were lower, and hospital duration was longer. And the incidence of respiratory distress, transient tachypena of newborn, intraventricular hemorrhage and metabolic abnormalities were higher, but the incidence of meconium aspiration syndrome was lower compare to the term infant group. CONCLUSIONS: Maternal mortality was not different. However, neonatal mortality was higher in late preterm infants. In late preterm group, the mothers had higher rate of autoimmune disease and obstetric complication, and the infants had higher morbidity compare to the term group. When the obstetrician decides on delivery time in high risk pregnancy, maternal medical condition and neonatal outcome should be considered.

OBJECTIVE: To evaluate the initial maternal and perinatal outcomes of fetoscopic laser photocoagulation for the treatment of twin-to-twin transfusion syndrome (TTTS) in a referral center in Brazil. METHODS: This prospective observational study analyzed 24 fetoscopic laser photocoagulation procedures at 18–26 weeks of gestation. TTTS severity was determined using the Quintero classification. Blood vessels that crossed the interamniotic membrane were nonselectively photocoagulated. The χ2 test and Mann-Whitney U test were used for the statistical analysis. RESULTS: The mean (±standard deviation) age of pregnant women, gestational age at surgery, surgical time, gestational age at birth, and newborn weight were 32.2±4.1 years, 20.7±2.9 weeks, 51.8±16.7 minutes, 30.5±4.1 weeks, and 1,531.0±773.1 g, respectively. Using the Quintero classification, there was a higher percentage of cases in stage III (54.2%), followed by stages IV (20.8%), II (16.7%), and I (8.3%). Ten (41.7%) donor fetuses died and 14 (58.3%) donor fetuses survived until the end of gestation. Placental insertion location (anterior vs. posterior) did not affect the incidence of iatrogenic septostomy, surface bleeding, and premature rupture of membranes until the end of gestation. The death rate of donor and recipient fetuses before 24th gestational week increased with severity of TTTS. CONCLUSION: The maternal and perinatal outcomes resulting from the implementation of a new minimally invasive surgical technique are in line with those obtained in major centers worldwide, considering the learning curves and infrastructures.

OBJECTIVE: The aim of this study was to evaluate the association between prenatally diagnosed isolated single umbilical artery (iSUA) and perinatal outcomes. METHODS: We searched Medline, Embase, the Cochrane Library, and KoreaMed from inception to January 2016, with no language or regional restrictions, for cohort and case-control studies reporting on the relationship of iSUA and perinatal outcomes. We assessed the odds ratios (ORs) and 95% confidence intervals (CIs) for the occurrence of small for gestational age, preterm birth, pregnancy-induced hypertension, neonatal intensive care unit admission, and perinatal mortality in fetuses with iSUA compared with those in fetuses with three vessel cord. RESULTS: Eleven articles totaling 1,731 pregnancies with iSUA met the selection criteria. Studies varied in design, quality, outcome definition, and results. Meta-analysis carried out within predefined groups showed that the presence of an iSUA was associated with small for gestational age (OR, 2.75; 95% CI, 1.97 to 3.83; P<0.00001), preterm birth (OR, 2.10; 95% CI, 1.72 to 2.57; P<0.00001), pregnancy-induced hypertension (OR, 1.62; 95% CI, 1.00 to 2.63; P=0.05), neonatal intensive care unit admission (OR, 2.06; 95% CI, 1.33 to 3.19; P=0.001), and perinatal mortality (OR, 2.29; 95% CI, 1.32 to 3.98; P=0.003). CONCLUSION: Pregnancies complicated by iSUA are at increased risk for small for gestational age, preterm birth, pregnancy-induced hypertension, neonatal intensive care unit admission and perinatal mortality. Further, large prospective cohort studies are required to improve the quality of prenatal counseling and the neonatal care for pregnancies with iSUA.

To what extent the risks of neonatal morbidities are directly related to premature birth or to biological mechanisms of preterm birth remains uncertain. We aimed to examine the effect of exposure to amniotic fluid (AF) infection and elevated cytokine levels on the mortality and pulmonary, intestinal, and neurologic outcomes of preterm infants, and whether these associations persist after adjustment for gestational age at birth. This retrospective cohort study included 152 premature singleton infants who were born at ≤ 32 weeks. AF obtained by amniocentesis was cultured; and interleukin-6 (IL-6) and IL-8 levels in AF were determined. The primary outcome was adverse perinatal outcome defined as the presence of one or more of the followings: stillbirth, neonatal death, bronchopulmonary dysplasia, necrotizing enterocolitis, intraventricular hemorrhage, and periventricular leukomalacia. Logistic regression analysis was adjusted for gestational age at birth and other potential confounders. In bivariate analyses, elevated AF IL-6 and IL-8 levels were significantly associated with adverse perinatal outcome. These results were not changed after adjusting for potential confounders, such as low Apgar scores, mechanical ventilation, and surfactant application. However, the independent effect of elevated cytokine levels in AF disappeared when additionally adjusted for low gestational age at birth; consequently, low gestational age remained strongly associated with the risk of adverse perinatal outcome. In conclusion, elevated levels of pro-inflammatory cytokines in AF are associated with increased risk of adverse perinatal outcomes, but this risk is not independent of low gestational age at birth. Culture-proven AF infection is not associated with this risk.

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.

Fetal death is an important indicator of national health care. In Korea, the fetal mortality rate is likely to increase due to advanced maternal age and multiple births, but there is limited research in this field. The authors investigated the characteristics of fetal deaths, the annual changes in the fetal mortality rate and the perinatal mortality rate in Korea, and compared them with those in Japan and the United States. Fetal deaths were restricted to those that occurred at 20 weeks of gestation or more. From 2009 to 2014, the overall mean fetal mortality rate was 8.5 per 1,000 live births and fetal deaths in Korea, 7.1 in Japan and 6.0 in the United States. While the birth rate in Korea declined by 2.1% between 2009 and 2014, the decrease in the number of fetal deaths was 34.5%. The fetal mortality rate in Korea declined by 32.9%, from 11.0 in 2009 to 7.4 in 2014, the largest decline among the 3 countries. In addition, rates for receiving prenatal care increased from 53.9% in 2009 to 75.0% in 2014. Perinatal mortality rate I and II were the lowest in Japan, followed by Korea and the United States, and Korea showed the greatest decrease in rate of perinatal mortality rate II. In this study, we identified that the indices of fetal deaths in Korea are improving rapidly. In order to maintain this trend, improvement of perinatal care level and stronger national medical support policies should be maintained continuously.

Spontaneous hepatic rupture, which is a complication of hypertension in pregnancy, is extremely rare. However, high maternal and perinatal mortality rates are observed. Several factors, namely, age over 30 years, multiparity, severe preeclampsia, or HELLP syndrome (a group of symptoms which include hemolytic anemia, hepatic enzyme increase, and thrombocytopenia), are associated with this condition. An autopsy case of a woman with twin pregnancy was studied. She was at 36 weeks of gestational age and suffered from the sudden development and rapid progression of hypertension. Moreover, she died because of spontaneous hepatic rupture despite an emergency operation. Autopsy revealed a capsular rupture of the right lobe of the liver with numerous blood clots and hypovolemic signs, such as weak postmortem lividity and palor of the skin and conjunctiva. A close examination of the trunk and liver for the classification of the cause of rupture and an assessment of medical history, such as preeclampsia, are needed during postmortem examination of pregnant women with hepatic rupture or her fetus. To the best of our knowledge, this fatal complication in pregnant women is not yet presented in postmortem examinations in Korea. Thus, we report the findings of this case to share the knowledge.

PURPOSE: The neonatal mortality rate in Japan has currently been at the lowest level in the world. However, it is unclear whether there are still some potentially preventable neonatal deaths. We, therefore, aimed to examine the backgrounds of neonatal death and the possibilities of prevention in a region of Japan. MATERIALS AND METHODS: This is a population-based study of neonatal death in Shiga Prefecture of Japan. RESULTS: The 103 neonatal deaths in our prefecture between 2007 and 2011 were included. After reviewing by a peer-review team, we classified the backgrounds of these neonatal deaths and analyzed end-of-life care approaches associated with prenatal diagnosis. Furthermore, we evaluated the possibilities of preventable neonatal death, suggesting specific recommendations for its prevention. We analyzed 102 (99%) of the neonatal deaths. Congenital malformations and extreme prematurity were the first and the second most common causes of death, respectively. More than half of the congenital abnormalities (59%) including malformations and chromosome abnormality had been diagnosed before births. We had 22 neonates with non-intensive care including eighteen cases with congenital abnormality and four with extreme prematurity. Twenty three cases were judged to have had some possibility of prevention with one having had a strong possibility of prevention. Among specific recommendations of preventable neonatal death, more than half of them were for obstetricians. CONCLUSION: There is room to reduce neonatal deaths in Japan. Prevention of neonatal death requires grater prenatal care by obstetricians before birth rather than improved neonatal care by neonatologists after birth.

9.Fetal heart rate monitoring: from Doppler to computerized analysis.
Obstetrics & Gynecology Science 2016;59(2):79-84
The monitoring of fetal heart rate (FHR) status is an important method to check well-being of the baby during labor. Since the electronic FHR monitoring was introduced 40 years ago, it has been expected to be an innovative screening test to detect fetuses who are becoming hypoxic and who may benefit from cesarean delivery or operative vaginal delivery. However, several randomized controlled trials have failed to prove that electronic FHR monitoring had any benefit of reducing the perinatal mortality and morbidity. Also it is now clear that the FHR monitoring had high intra- and interobserver disagreements and increased the rate of cesarean delivery. Despite such limitations, the FHR monitoring is still one of the most important obstetric procedures in clinical practice, and the cardiotocogram is the most-used equipment. To supplement cardiotocogram, new methods of computerized FHR analysis and electrocardiogram have been developed, and several clinical researches have been currently performed. Computerized equipment makes us to analyze beat-to-beat variability and short term heart rate patterns. Furthermore, researches about multiparameters of FHR variability will be ongoing.

We report on an abdominal pregnancy in human immunodeficiency virus-positive mother, currently on antiretroviral therapy, which was discovered incidentally while training the obstetric ultrasound capacity building program. Although abdominal pregnancy is a rare form of ectopic pregnancy, it may be more common in women with HIV infection because they tend to have a higher rate of sexually transmitted diseases than the general population. The positive diagnosis of abdominal pregnancy is difficult to establish and is usually missed during prenatal assessment particularly in settings that lack routine ultrasound examination as is the case in most developing countries. For the management of abdominal pregnancy, surgical intervention is recommended and removal of the placenta is a key controversy. Ultrasonography is considered the front-line and most effective imaging method and an awareness with a high index of suspicion of abdominal pregnancy is vital for reducing associated high maternal and even higher perinatal mortality.
