This study was undertaken to assess the potential of body mass index (BMI) as a risk factor for massive hemorrhage (MH) after cesarean section (CS) in patients with placenta previa. We retrospectively reviewed the medical records of patients who underwent CS for placenta previa between January 2010 and December 2018. MH was defined as an estimated blood loss ≥2,000 mL during surgery. Clinical characteristics, including BMI, were compared between the groups with and without MH. Subsequently, multivariable logistic regression analysis was conducted to identify the independent risk factors for MH. A total of 189 patients were included in this study. MH was observed in 28 patients (14.8%). According to the multivariable logistic regression analysis results, the risk factors independently associated with MH were BMI at delivery (adjusted odds ratio [aOR], 1.19; 95% confidence interval [CI], 1.04-1.35; P=0.012), placenta accrete (aOR, 24.55; 95% CI, 2.75-219.02; P=0.004), and total previa degree (aOR, 9.86; 95% CI, 2.71-35.96; P=0.001). The study findings showed that maternal obesity, namely a higher BMI at delivery, was an independent risk factor for MH after CS in patients with placenta previa. Close attention should be paid to the potential risk of hemorrhage associated with maternal obesity as well as the well-known risk factors of placenta accreta and total previa degree.

This study assessed risk factors for blood transfusion after Cesarean section in patients with partial placenta previa. We retrospectively reviewed the medical records of 149 patients who underwent Cesarean sections for partial placenta previa between January 2010 and October 2021. Clinical characteristics were compared between the two groups: the blood transfusion group (n=22), defined as patients who received a blood transfusion during surgery or within 24 hours after surgery, and the non-blood transfusion group (n=127), which included other patients. Multivariable logistic regression analysis identified two risk factors independently associated with blood transfusion: antenatal hemorrhage (adjusted odds ratio [aOR], 16.283; 95% confidence interval [CI], 4.405-60.190; P<0.001) and preoperative hemoglobin (g/dL) (aOR, 0.427; 95% CI, 0.246-0.739; P=0.002). Thus, patients who are at risk for these two factors should be carefully managed with sufficient preparation for blood transfusion and anesthetic management.

A clinical study was made on 365 low birth weight infant and 406 normal birth weight infant who had been born at Kangnam St. mary's Hospital during past 3 years from Jan. 1, 1995 to Dec. 31, 1997. the data of this study were gathered through reviewing of medical records. 1. Comparison of general characteristic with of obstetric characteristic 1) Old maternal age, previous abortion and previous LBWI delivery in the group of low birth weight infant(LBWI) mother were more prevalent than those in the group of normal birth weight infant(NBWI)mother 2) Cesarean section, abnormal presentation and multiple pregnancy in the group of LBWI mother were prevalent than those in the group of NBWI mother. 3) regular antenartal care and visiting rate of tertiary hospital in the group of LBWI mother were more prevalent than those in the group of NBWI mother. 2. Frequency of low birth weight infant 1) Anmual average frequency of LBWI was 6.5% and monthly frequency was the highest in January and december. 2) The frequency of LBWI was the highest in 37-40wks of gestational age and was the highest in 2251-2500 gm of birth weight. 3) The frequency of congenital anomaly in the group of LBWI was more prevalent than that of NBWI. 3. Mortality rate of LBWI The mortality rate of LBWI was 9.2%. The highest mortality rate was noted before 27wks of gestational age, less than 1000gm of birth weight and within 12hrs of delivery. 4. The most common complication of pregnant women was pre-term labor, the most complication relating to placenta was premature rupture of membrane(PROM) and the most fetal complication was fetal distress in delivered LBWI. 5. Significant relating factors of low birth weight infant delivery were associated with maternal age, previous delivery, previous low birth weight delivery, pre-eclampsia, anemia, oligohydramnios, PROM, placenta previa, abruptio placenta, fetal sex, fetal distress and congenital anomaly.

Ultrasonographic examination in the obstetrics not only makes easy of the diagnosis of Hydrocephalus, placenta previa, anencephalus and ectopic pregnancy, etc, but also guaranteed its excellence in the diagnosis of women gynecology disease. Especially in case that it doesn't affect radiation hazard on the embryo, its efficiency keeps increasing and it is spotlighted to many clinic doctors. Even though in general hospital we often observe congenital hydrocephalus in Med. Dept. which entirly undergoes the medical examination to the insured, we don't observe even the women delivered with child and it is very difficult to find a rare congenital hydrocephlus throughout other present insurance companies. We inspected a congenital hydrocephalus, which other medical equipments of present insurance companies have many difficulties in the medical examination, accompanied by meningoencephalocele by ultrasonic diagnosis. We analyzed and compared the data by ultrasonic diagnosis with that of surgical diagnosis and the results are follows; 1) We could correctly describe meningoencephalocele by ultrasonic diagnosis. 2) It was able to be diagnosed in LMP 22 weeks. 3) BPD has about 10 mm higher than normal value in LMP 22 weeks. 4) Dilatation of lateral ventricle was observed in LMP 22 weeks. 5) As paralled with ultrasonic diagnosis in pregnancy medical examination, accepting declines including the risk rate can be restrained.

Objectives: Regression, while not a core symptom of autism spectrum disorder (ASD), has been suggested to be a distinct subtype by previous studies. Therefore, this study aimed to explore the prevalence and clinical differences between those with and without regression in children with ASD. Methods: This study includes data from toddlers and young children aged 2-7 years acquired from other projects at Seoul National University Bundang Hospital. The presence and characteristics of regression were explored using question items #11-28 from the Autism Diagnostic Interview-Revised. Chi-square and independent t-tests were used to compare various clinical measurements such as autistic symptoms, adaptative behavior, intelligence, and perinatal factors. Results: Data from 1438 young children (1020 with ASD) were analyzed. The overall prevalence rate of regression, which was mainly related to language-related skills, was 10.2% in the ASD group, with an onset age of 24 months. Regarding clinical characteristics, patients with ASD and regression experienced ASD symptoms, especially restricted and repetitive interests and behaviors, with greater severity than those without regression. Furthermore, there were significant associations between regression and hypertension/placenta previa. Conclusion: In-depth surveillance and proactive interventions targeted at young children with ASD and regression should focus on autistic symptoms and other areas of functioning.

Objectives : This study was conducted to explore the relating factors with the delivery of low-birth-weight infants in Pyungtaek city. Methods : A questionnaire survey was obtained from 51 mothers with low-birth-weight babies and 90 mothers with full-term normal babies from April to October in 2001. Questionnaire consisted of demographic characteristics, dietary habits including alcohol. drugging, and smoking, past and present disease, prenatal risk factors and prenatal check-up, and complications related to labor and delivery. Results : 1. In the low-birth-weight infants group, father's education level and mother's height were significantly lower, and proportion of old age mothers was significantly higher than those of the normal infant group. 2. Mothers with low-birth-weight infants experienced more premature rupture of membrane, placenta previa, ecclampsia, and twin pregnancy than mothers with normal infants. Gestational period of mothers with low-birth-weight infants was significantly shorter than that of mothers with normal infants. 3. No differences were found in eating habit, alcohol and drug ingestion, smoking, exposing to dangerous materials in two groups, but both groups were highly exposed to indirect smoking, although mothers rarely smoke. Conclusion : The findings of this study indicate that high risk group such as less educated, or older mothers need more prenatal health assessment and support from public health services. Addition to determine the risk factors related to the delivery of low-birth-weight infants, public health nurses pay more attention and develop efficient management system for vulnerable women and infants.

Objective : To evaluate the safety and efficacy of selective fetal reduction (SFR) and compare the outcome of twin pregnancy after SFR in multiple pregnancy induced by assisted reproductive technology (ART) with that of natural twin pregnancy. Methods : From September 1995 to March 2002 in Ajou University Hospital, SFR was performed in 79 patients whose gestational sacs were more than 3. Of these 79 patients, 47 patents resulted in twin pregnancy after SFR. SFR was performed using transvaginal intracardiac KCl injection at gestational age of $6{\sim}9$ weeks. Control group was composed of 264 patients with natural twin pregnancy, who delivered after intrauterine pregnancy at 24 weeks, from June 1994 through December 2002. We compared Obstetric and perinatal outcomes between SFR group and natural twin group. Results: Among 47 patients with twin pregnancy after SFR, 2 spontaneous abortion were occurred at intrauterine pregnancy at 8 and 19 weeks. Obstetrical and perinatal outcomes were available in 43 patients. Single intrauterine fetal death was occurred in 1 of 43 (2.3%) patients in SFR group. Incidence of preterm labor, premature rupture of membrane, preeclampsia and placenta previa were similar, but gestational diabetes mellitus (GDM) was occurred more frequently in SFR group (3 (7.0%) vs 4 (1.5%), p=0.02). Mean gestational age, mean birth weight, incidence of discordancy, use of intubation and ventilation, incidence of fetal anomaly, low (<7) Apgar score and intrauterine growth restriction were similar in both groups. Conclusion: Twin pregnancy after SFR has the increased incidence for GDM but other obstetric and perinatal outcome was similar compared with natural twin pregnancy. So SFR is a safe and effective procedure, so we suggest SFR is needed in multifetal pregnancy more than triplet.
