Study on maternal mortality and maternal mortality-induced basic causes in Thai Binh province during 1991-2000. The results: maternal mortality by different causes is 61.1%. Direct causes on maternal mortality are uterine hemorrhage, toxemia of pregnancy, infection, rupture of uterus and curettage for abortion. Maternal mortality by indirect causes is 34.4%, in which, nearly a half of deaths due to pregnant cardiopathies and over a half of deaths due to other indirect causes. There are 6 cases of maternal mortality not diagnosed. Maternal mortality occurs mainly at the age from 25 to 39 years old

OBJECTIVE: The aim of this study was to evaluate the role of lower uterine segment thickness in predicting an actual delivery date and to determine the factors affecting the depth of lower uterine segment. METHODS: Sixty patients with singleton gestation were weekly measured for their lower uterine segment (LUS), cervical length, cervical gland thickness and AFI by ultrasonography from 36 weeks. The regression analysis was carried to find out the relevance between LUS and the remaining days to birth and Pearson correlation analysis was performed for relevance between LUS and other factors such as maternal age, parity, cervical length, cervical gland thickness, and AFI. RESULTS: LUS became thin as cervical length decreasing. However, the relevance between LUS and other factors such as age, parity, cervical gland thickness, and AFI was not found. While individual LUS thickness is decreasing as delivery date becomes closer, LUS thickness as a group is found not to be related with the delivery date. CONCLUSION: In term pregnancy, LUS thickness decreases with cervical change but it cannot predict the delivery date.

PURPOSE: This study was conducted to analyze recent trends and causes of maternal mortality in Korea between 2009 and 2014. METHODS: We investigated trends and causes of maternal death using the data from Complementary Investigations on the Infant, Maternal, and Perinatal Mortality carried out by Statistics Korea between 2009 and 2014. Maternal age, administrative district, causes of death and gestational age at the time of death were collected from data. Statistics including maternal mortality ratio (MMR) and maternal mortality rate were calculated. We also analyzed MMR according to the age, and administrative districts. The causes of maternal death were sorted and classified using International Classification of Diseases and World Health Organization recommendations. RESULTS: The average MMR during 6 years was 13.16 and maternal mortality rate was 0.45. MMR was highest in 2011 (17.2) and lowest in 2012 (9.9). The average MMR of the administrative districts varied greatly from 7.51 (Gwangju) to 26.84 (Jeju). The average MMR during the study period was lowest in maternal age of 20-24 (6.9), and highest in 45-49 (143.7). On average, direct and indirect maternal deaths accounted for 66.2% and 29.9% of total maternal death, respectively. The three most common causes of maternal deaths were obstetrical embolism (24.4%), postpartum hemorrhage (18.3%), and hypertensive disease of pregnancy (5.5%) in decreasing order of frequency. CONCLUSION: Although MMR is decreasing during the study period, it fluctuates widely according to maternal age, districts, and constant effort for improvements is necessary. To reduce maternal deaths, solution to control preventable causes of maternal deaths, careful management of pregnancies with advanced maternal age, and policy to solve the discrepancy in the medical services among diverse regions in the country are needed.

OBJECTIVE: To compare the obstetric complications and perinatal outcomes of twin pregnancies conceived by In Vitro Fertilization and Embryo Transfer to twin pregnancies conceived naturally. METHODS: Maternal and neonatal data were reviewed for all twin pregnancies. All twin pregnancies (n=116) were divided into IVF twin pregnancyes group (n=43) and naturally conceived twin pregnancyes (n=72). The obstetric and perinatal outcomes were compared and analysed. Statistical analysis was performed using student's t-test, x2 test, and Fisher exact test. Statistical significance was defined as p<0.05. RESULTS: There were no significant differences in maternal age and gestational age between two groups but nulliparity was higher in IVF-ET twin group than naturally conceived twin group. Also no differences of obstetrics and perinatal outcomes were seen between two groups. CONCLUSION: Although twin pregnancies following IVF-ET are more likely to result in bad prognosis, in this study obstetric and perinatal outcomes are comparable to those of naturally conceived twin pregnancies.
