RESUMEN
OBJECTIVE: The birth weight distributions are obtained to be classified according to the duration of pregnancy, and then compared with other results already published in literature to verify the difference. METHODS: A total of 17,291 deliveries in Gachon medical center hospital from January 1996 to December 1999 is retrospectively reviewed. The data of 28~42th week of gestation are analysed, and the 10th, 25th, 50th, 75th and 90th percentiles of birth weight are determined for each week and also according to sex and parity. Furthermore the 10th, 50th, 90th percentiles are compared with those from other reports. RESULTS: 1. The 10th, 50th, 90th percentiles of birth weight classifed according to gestational age are as follow : in 28th week of pregnancy, 1,068, 1,240 and 1,812 g; in 32th week, 1,470, 1,890 and 2,266 g; in 36th week, 2,170, 2,720 and 3,240 g; in 40th week, 2,910, 3,370 and 3,870 g; in 42th week, 2,977, 3,475 and 4,023 g.2. The mean birth weight of the male neonates is greater than that of the female ones from 37th week to 41th week (p<0.01).3. Comparisons of 10th, 50th, 90th percentiles of birth weight with Park groups show that there is an increase of birth weight by 100~144 g. CONCLUSION: Comparison of the birth weight-gestational age table with ones published by other groups shows that infants tend to be heavier.

We experienced a case of Ebstein's anomaly prenatally by fetal sonography. Ebstein's anomaly is a rare congenital heart defect characterized by abnormally downward displacement of the septal and posterior leaflets of the tricuspid valve. In the absence of tricuspid regurgitation, this condition may be completely asymptomatic. On the other hand, symptomatic newborns often develop life-threatening congestive heart failure. A 30-year-old multiparous woman was referred for the evaluation of fetal cardiac defect at 26th gestational week from a private clinic. Fetal ultrasonography showed markedly enlarged right atrium and downward displacement of tricuspid valve into the right ventricle. After discussion with the patient, the pregnancy was terminated and Ebstein's anomaly was confirmed by autopsy.

OBJECTIVE: Our purpose was to compare the pregnancy outcomes of nulliparous women aged 40 years and older with those of nulliparous women under 35 years of age. METHODS: From January 1989 to December 1998 total 57,563 deliveries were seen in Gachon Gil Medical Center. Among them we experienced 59 cases of nulliparas at 40 years and older. These women were compared with 188 young nulliparas under 35 years of age as the control group. The statistical analysis was performed using Chi-square tests, and statistical significance was defined as p<0.05. RESULTS: The incidence rate of elderly nulliparas aged 40 years and older was increased from 0.04% in 1989 to 0.30% in 1998. The age distribution was from 40 years to 45 years. The gravidity of eldery nulliparas was 2.2 in comparison with 1.6 in control group. The incidence of uterine myoma, gestational DM, IUGR and oligohydramnios was significantly high rate in elderly nulliparas. There was significantly high rate of cesarean section in elderly nulliparas(88.1%) in comparison with control group(40.4%). The reasons of cesarean section were her demand(39.0%), CPD(15.3%) and breech presentation(13.6%) in decreasing order. The preterm delivery rate was 10.2% in elderly nulliparas in comparison with 4.3% in the control group. Placenta accreta and uterine atony were significantly high in elderly nulliparas and mean estimated blood loss was also high. There was no difference in 5-minute Apgar score between both group, but there were more cases of neonatal intensive care unit admission in neonates of elderly nulliparas(6.8% vs 0%). CONCLUSION: The incidence of elderly nulliparas is continuously increasing. The elderly nulliparas and their babies are at greater risk than young women. Therefore all elderly nulliparas aged 40 years and older can be regarded as high risk patients and they must be managed with careful attention.

OBJECTIVE: To compare the second and third cesarean section by clinical and statistical analysis. METHODS: From June 1993 to February 1997, we experienced 296 cases of the third cesarean section and 541 cases of the second cesarean section. We analyzed their incidence, age distribution, gestational week at operation, weight distribution of baby at birth, hemoglobin change, estimated blood loss during operation, obstetrical complication, combined operation, and degree of pelvic adhesion, presence of wound dehisence of uterus, post operative complication. RESULTS: Of the total deliveries, overall incidence of cesarean section was 51.4%, while the incidence of the second cesarean section was 16.0%, and that of the third cesarean section was 1.1%. In the third cesarean section the age group of 31-35 was most common(49.7%), and the most common gestational week at operation was 39th week(43.9%). In the third cesarean section, the hemoglobin change of 1.0g% less was most common(95.2%), and the most common amount of estimated blood loss was 400-600ml(61.0%). There was statistically significant difference of the blood transfusion rate between the third cesarean section(41 cases, 13.8%, p=0.04) and second cesarean section(27 cases, 5.0%). The most common combined operation in the third cesarean section was tubal ligation(51.7%), and the others were bladder wall repair(2.0%), cesarean hysterectomy(1.7%). In the third cesarean section, the incidence of mild intraabdominal adhesion was 16. 9% and that of severe adhesion was 11.8%. It was statistically significant compared to the second cesarean section. Among the complications of the third cesarean section, there were 9 cases of placenta accreta(3.0%), 4 cases of placenta previa totalis(1.4%), and 1 case of uterine rupture, uterine atony, uterine arterial rupture(0.3% each other), and did not proved statistical significance. CONCLUSION: In this study, we found that the rate of blood transfusion, cesarean hysterectomy, bladder wall repair, and the degree of intraabdominal adhesion were more common in the third cesarean section than second section. But, if pre- & postoperative management is adequate, maternal mobidity and neonatal mobidity is not affected.
