We had experienced 2 cases of acute subdural hematoma due to vitaimin K(vit. K) deficiency. They were 44-and 42-day-old. After the adminstration of vit.K1, prolonged prothrombin time(PT) and activated partial thromboplastin time(APTT) were corrected, so the surgical treatment ws performed. We supposed the predisposing factors were breast feeding and unknown hepatic pathology. No complication remained to one infant but the other multiple cerebral infarctions. The etiology, pathogenesis, diagnosis, prevention are discussed. We insist on neonatal administration of vit. K1 for the prevention of bleeding tendency. If intracranial hemorrhage develops, we must keep in mind that the early neurosurgical intervention may be needed.

To assess the adequacy of medical manpower and medical fee for the newborn nursery care, the author visited 20 out of 24 hospitals with the pediatric training program in Youngnam area between July 29 and August 14, 1991. Total number of newborn, both normal and sick, admission and discharge in 1--30 June 1991 was obtained from the logbook of nursery. Head nurse and staff pediatrician of the nursery were interviewed to get the current staffing for the nursery and their subjective opinion on the adequacy of nursery manpower and the difficulties in recruiting manpower. Average medical fee charged for the maternity and normal newborn nursery care was obtained from the division of self-audit of medical insurance claim of each hospital. Average minimum requirement of nursing care time for one normal newborn per day was 179.5 (+/-58.6) minutes; 2023(+/-50.7) minutes for the university hospitals and 164.2(+/-60.5) minutes for the general hospitals. The ratio of minimum requirement of nursing care time and available nursing time was 1.42 on the average. Taking the additional requirement of nursing care for the sick newborns into consideration, the ratio was 2.06. The numbers of R. N. and A. N. in the nurserys of study hospitals were 31%, and 17%, respectively, of the nursing manpower for the nursery recommended by the American Academy of Pediatrics. These findings indicate that the nursing manpower in newborn nursery is in severe shortage. Ninety percent of the head nurses and 85% of the staff pediatrician stated that the newborn nursery is short of R.N. and 75% of them said that the nurse's aide is also short. Major reason for not recruiting R.N. was the financial constraint of hospital. For the recruitment of nurse's aide, short supply was the second most important reason next to the financial constraint. However, limit of quarter in T.O. was the major reason for the national university hospitals. Average total medical fee for the maternity and newborn nursery cares of a normal vaginal delivery who stayed two nights and three days at hospital was 219,430Won. Out of the total medical fee, 20,323Won(9.3%) was for the newborn nursery care. In case of C-section delivery six nights and seven days, who stayed otal medical fee was 732,578Won and out of the total fee 76,937Won (12.0%) was for the newborn care. Cost for a newborn care per day by cost accounting was 16,141Won for the tertiary care hospitals and 14,576Won for the all other hopitals. The ratio of cost and the fee schedule of the medical insurance for a newborn care per day was 5.0 for the tertiary care hospitals and 4.9 for the all other hospitals. Considering the current wage level of the medical personnel, capital investment for the hospital facilities and equipments, and the cost for hospital maintenance, it is hard to expect adequate quality care in the newborn nursery under the current medical insurance fee schedule.

At first, we review a sample size estimation method for log-rank test in survival analysis. Although it is widely used these days, it has a weakness for practical use. We propose a modification method to avoid the weakness.

A Comparative study was retrospectively performed with 374 infants in order to find protective effect of breast feeding for infection. This study shows that breast feeding protect infant against gastrointestinal and respiratory infection. Breast feeding offers advantage by reducing gastraintestinal and respiratory infection when they should maintain breast feeding for at least three months. 1) First year morbidity increased with extent of artificial feeding and was nearly two fold for babies not breast-fed. 2) Prescence of older sibling, low birth weight and male sex are associated with increased morbidity. 3) Infant illness from 0~3 months, 4~6 months, 7~10 months, 11~12 moths was analyzed. Compared with the 108 bottle fed babies, the babies who had been partially (40) or fully (136) breast fed had significantly lower rate of gastrointestinal illness at 7~10 month (p<0.05), 11~12 month (p<0.005) and respiratory illness at 7~10 month (p<0.05). 4) Between the early weaning group (90) and the bottle group (108) showed no siggnificant difference. 5) Among the babies observed throughout the first year of life, 35 (9%) and 46 (12) were admitted to hospital with gastrointestinal and respiratory infection. Babies who were breast fed for more than 3 month had significant lower rate for hospital admission due to gastrointestinal and respiratory infection when compared with bottle fed babies. Breast feeding durning more than 3 month of life confers protection against gastrointestinal and respiratory infection.

Intracerebral hemorrhage secondary to vitamin K deficiency is presented in three newborn infants: 4 days, 28 days and 21 days of age respectively. After the administration of vitamin K(5-10 mg) either intravenously or intramusculary, prolonged prothrombin time(PT) and partial thromboplastin time(PTT) were corrected promptly. Vitamin K dependent coagulation factor deficiency due to vitamin K deficiency is accounted for the pathogenesis of hemorrhage. The possible causes of vitamin K deficiency, diagnostic methods and treatment of this disease entity are reviewed. Neurosurgeons as well as pediatricians should remain alert for the development of intracerebral hemorrhage caused by vitamin K deficiency in neonatal period.

9.Effect of Nicardipine on Pressor Response to Raised Intracranial Pressure and alpha-Adrenoceptor Agonist.
Journal of Korean Neurosurgical Society 1989;18(1):23-31
The effect of nicardipine was investigated on hypertension due to raised intracranial pressure, pressor response of alpha-adrenoceptor agonists in the dissected thoracic aorta. Intracerebroventricular(icv) and intravenous(iv) nicardipine produced dose-dependent depressor response and bradycardiac effect, especially marked response was observed following iv injection. The pressor response to raised intracranial pressures was potentiated following iv injection of 50 microgram/kg nicardipine but was markedly inhibited following iv 100 microgram/kg injection, and was not affected following icv 50 microgram/kg administration but was markedly inhibited following icv administration of 100-200 microgram/kg nicardipine. The nicardipine inhibited contractile effect of KCI 35 mM in a dose-dependent fashion but did not affect that of Ne and ME. These data suggest that nicardipine caused hypotensive effect by blocking calcium influx in the peripheral vessels and that direct effect of nicardipine on central nervous system involves the hypotensive action. Conclusively, the inhibitory effect of nicardipine on the pressor response to the intracranial pressure elevation may be induced by these two mechanisms.

This study was undertaken for the clinical analysis and evaluation on 121 patients with incompetent internal os of the cervix, who were admitted and treated with McDonald operation or Shirodkar operation at the Soonchounhyang Medical Center from January 1991 to December 1995. The results of this study were as follows : 1. The incidence of this IIOC was 1.1% of 11,116 cases of total delivery. 2. The mean age of IIOC was 31.7 years old. 3. The average number of gravida was 3.2. 4. The most common contributary factor was previous history of artificial abortion (51.2 %), and midtrimester abortion (17.4 %), cervical laceration due to previous vaginal delivery (8.3 %) etc. was followed. 5. The success rate of operation was 76 %, and the highest success rate (85.7 %) was reveald with period from 15th weeks to 16th weeks of gestation. 6. When cervical dilatation was abscent or small, the success rate of operation was high. 7. The factors of failed operation were preterm labor (58.7 %), PROM (34.5 %), and PIH, bleeding. 8. The delivery method after operation was vaginal delivery in 83 cases (68.6%) and cesarean section in 38 cases (31.4 %).
