A statistical observation was performed on 13,317 cases of neonates who had been delivered at Taegu Catholic Hospital during the past 3 years from Jan, 1st 1988 to Dec. 31st 1990. The results obtained were as follows: 1) Among 13,317 neonates, the male was 7,234 and the female 6,083, with the sex ratio of male to female being 1.19:1 2) Percentage distribution by birth weight was 5.6% for 2.500gm or less, 3.3% for 4,001gm or more. The mortality rate was 8.4 per 1,000 live births and 61.1% for very low birth weight infants. 57.1% of neonatal death occured within 24 hours after birth and the most common cause of death was prematurity (53.6%). 3) The mean growth data at birth were as following: Weight: 3,253+/-484gm in male, 3,160+/-456gm in female; Height: 50.11+/-2.59cm in male, 49.57+/-2.50cm in female; Head circumference: 33.60+/-1.74cm in male, 33.12+/-1.64cm in female; Chest circumference: 32.83+/-1.83cm in male, 32.41+/-1.75cm in female. 4) Among 13,317 noenates, 352 (2.6%) were under 37 wks and 555 (4.2%) above 42 wks and 92.6% very low birth weight infants under 37 wks. 5) 44.2% of 13,317 neonates, was the highest-density distribution which was between 47.5~52.4cm by length and 3,001~3,500gm by weighing. 6) The admission rate was 13.7% and the causes of admission in order of frequency were neonatal infection (47.9%), premature or low birth weight infant (12.9%), neonatal jaundice (11.3%), asphyxia neonatorum (6.9%), respiratory disress syndrome (5.4%), etc. 7) Among all neonates, 2.2% had neonatal asphyxia (a 1-minute Apgar score of 6 or less). The highest incidence was 19.7% in the breech delivery group by delivery mode and 33.6% in the prematurity by gestational age. 8) The types of delivery in order of frequency were spontaneous vaginal delivery (72.5%), Cesarean section (21.9%), vacuum delivery (5.0%), breech delivery (0.5%) and forceps delivery (0.1%). 9) The incidence of twin babies was 182 (91 pairs), 1.37% of all neonates, 1 pair per 145 neonates. Of all twins, 50.5% were below 2,500gm of birth weight and 20.9% premature. 10) The incidence of neonatal jaundice was 63.0%. Of icteric neonates, 8.2% had pathologic jaundice treated by phototherapy or exchange transfusion. 11) Among all neonates, there were 7,705 cases (57.9%) with high risk factors; the order of frequency was Cesarean section (37.8), meconium stained (13.3%), premature rupture of membranes over 24 hours (12.7%), birth weight 2,500gm or less (9.6%), etc.

OBJECTIVE: The purpose of this study was to review the incidence, clinicopathological feature, treatment, outcome in the series of childhood and adolescence with ovarian mass PATIENTS AND METHODS: Retrospective reviews of the medical recordings for 116 patients with ovarian mass under the age of twenty years old who were admitted, operated and confirmed with histopatholgical study at the department of obstetric and gynecology, Gachon medical school, Inchon, Korea for 8 years from Jan. 1993 till Dec. 2000. RESULTS: Of 116 the patients who underwent surgical treatment, the incidence of malignant ovarian tumors was 15 cases(12.9%). If ovarian neoplasm alone are considered, the rate of malignancy increases to 17.6%. The frequency of ovarian malignancies correlated inversely with patient age. In the 0-10 age group ,40% had malignancies, as compared with 20.3% in the 11-15 age group and 15.3% in the 16-20 age group. On histopathological classification, the tumors originated from germ cell tumors were 55.2%, epithelial cell tumors were 40%, and sex-cord stromal tumors were 4.7%. According to FIGO classification of malignant ovarian tumor, stage I(80%) was most common, followed stage IV(13.3%), stage II(6.6%) and III(0%). 13 of the 15 malignant ovarian tumors, unilateral salpingoophorectomy was done in an attempt for reproductive organ conservation; 2 cases of stage IV disease were treated with hystrectomy, bilateral salpingoophorectomy and omentectomy. On follow up, only two ovarian malignancy stage IV died within 3 months and another is well. CONCLUSION: The frequency with which ovarian meoplasms malignancy in the under 20 age group is 17.6%. Because of their malignant potential in young girl, prompt evaluation and treatment is imperative.
