국민건강 수준과 문제점의 파악, 보건사업의 기획 및 평가를 위해 정확한 출생과 사망에 관한 통계자료가 필수적이다. 그러나 출생신고 이전에 신생아가 사망하는 경우에 대부분 출생과 사망 모두를 신고하지 않아 영아사망률을 비롯한 보건통계를 산출하지 못하여 합리적인 보건사업의 기획 및 평가가 어려우며, OECD 회원국으로서 제시해야 할 기본적인 보건통계를 제시하지 못하고 있다. 또한 현행 출생신고자료에는 신생아와 산모의 건강상태에 관한 자료가 없어 보건서비스제공과 모자보건관련 역학적 연구에 활용 가치가 거의 없다. 지역보건의료정보화, 예방접종기록전산화, 미숙아 및 선천성기형아 등록 등 각종 등록 및 전산화사업이 진행중이나 이러한 사업들이 독립적으로 진행되고 있어 같거나 비슷한 자료의 중복 입력하게 되고, 상호 연계가 되지 않아 자료의 활용성이 낮고, 그 어느 사업도 전체 분모를 파악할 수 없는 단점이 있다. 이러한 문제들은 전산정보체계의 확립으로 해결할 수 있다. 약 99%의 분만이 의료기관에서 일어나고, 정부의 초고속 통신망을 비롯한 의료기관과 보건소의 전산화가 빠르게 진행되고 있어 전산정보체계를 위한 여건이 성숙되고 있다. 분만의료기관이 산모의 거주지 보건소로 직접 출생신고를 하면 보건소는 적기에 산모와 신생아에게 필요한 보건서비스를 제공할 수 있고, 보건소가 읍 면 동사무소로 출생신고 자료를 전송하면 산모는 동사무소에 가지 않고도 출생신고를 할 수 있으며, 보건통계자료수집과 출생신고관리에 필요한 인력과 시간을 절약할 수 있고, 정확한 생정통계를 얻을 수 있고, 예방접종기록과 미숙아 및 선천성기형아 등록은 쉽게 해결되고, 완전한 보건사업대상자의 database를 구축할 수 있어 평생건강관리체계의 기틀을 마련하게 된다. 이러한 전산신고체계를 확립하기 위하여 연자 등은 정부의 연구용역사업으로 전산프로그램과 표준신고양식과 신고체계를 개발하여, 포항과 천안시에서 2000년 3월에서 8월까지 시험 운영하였다. 시험운영결과 출생신고율은 99.9%이었으나 신생아사망의 전산신고율은 11.1%로 낮았다. 그러나 일단 출생신고된 신생아의 사망은 반드시 확인될 수 있는 것이 본 신고체계의 큰 장점이었다. 전산신고의 중요한 장애 요소는 현행법상 의료기관이 출생신고를 직접 할 의무가 없으므로 신고를 강요할 수 없고, 의료기관의 일손 부족으로 출생신고서를 충실하게 기재하지 못하는 것과 의료기관간의 전산화 수준의 차이가 심한 것이었다. 의료기관이 직접 신고를 하도록 하기 위하여 모자보건법 등 관련법 개정이 필요하며, 의료기관의 출생신고자료 송부에 대한 정당한 보상이 있어야 할 것이다. 의료기관 간의 전산화 수준의 차이는 data warehousing과 on-line analytical processing과 같은 기술을 이용하면 해결 가능할 것이다.

This study is a search for radiation protection effects of radiation exposure on the organogenic period during the prenatal period, which is known to be the most likely to have congenital malformations by radiation exposure. To study the radiation protection for the mixture of selenium that is strong antioxidant and folic acid that is essential vitamin for DNA synthesis, 2 Gy of radiation was irradiated to pregnant female rats. then, after 14 days of fetal birth, observing blood components, SOD(Superoxide Dismutase), histological changes and external malformations. There was a significant protective effect to reduce blood cell damage(p<0.05) in the irradiation group after selenium and folic acid mixture were administered than irradiation group, and the activation of SOD which is antioxidant enzymes was increased. In addition, confirmed the effect of suppressing the expression of apoptosis of small intestinal cells and the reduction of cerebral cortex layer reduction by radiation. thus, it was confirmed that the congenital malformations were reduced as a result of these protective effects. Based on these results, selenium and folic acid mixture may reduce the incidence of congenital malformations, and it will reduce the damage of the fetus caused by the exposure of the organogenic period due to accidents.

The aims of this study are to consider auditory physiological characteristics and to confirm audiological evaluation and interpretation in regards to cases of sensorineural hearing loss that observe an abnormal AB gap. Vestibulosaccular hearing occurs when there is an abnormally large air-bone gap (AB gap) in sensorineural hearing loss, also known as pure cochlear conductive hearing loss. Generally, an AB gap is caused by damage to the external and/or middle ear. In conductive hearing loss, loss of air condition hearing occurs due to a loss of resonance in the outer ear and/or impedance mismatching in the middle ear. Most of these types of hearing loss can be treated medically and surgically. However, there is no medical treatment for an AB gap in sensorineural hearing loss and hearing loss can worsen gradually or suddenly. In addition, many studies have reported that head trauma makes hearing loss even more serious. Therefore, in order to differentiate between conductive hearing losses, it is important to check whether or not there is an enlarged vestibular aqueduct by means of temporal bone computerized tomography and/or magnetic resonance imaging.

Purpose : This study was performed to evaluate the recent frequency of karyotypes in different sex chromosome abnormalities and to evaluate the age and clinical manifestations at diagnosis. Methods : Peripheral blood leukocytes were obtained from subjects who were clinically suspected to have sex chromosome abnormalities and referred to the cytogenetic laboratory in the Department of Pediatrics, Kyungpook National University Hospital from February 1981 to August 2001. Results : The relative frequencies of different sex chromosome abnormalities were Klinefelter(52 percent), Turner(42 percent), XXX syndrome(3 percent) and mixed gonadal dysgenesis(3 percent). The populations of different karyotypes in Klinefelter syndrome were 47,XXY(97 percent) and 46,XY/47,XYY(3 percent). The populations of different karyotypes in Turner syndrome were 45,X(67 percent,), mosaicism(23 percent), and structural aberrations(10 percent). The populations of different karyotypes in XXX syndrome were 47,XXX(67 percent,) and 46,XX/47,XXX(33 percent). All mixed gonadal dysgenesis were 45,X/46,XY. Eighty one percent of sex chromosome abnormalities was diagnosed after puberty. Patients diagnosed with Klinefelter and Turner syndrome in infancy showed nearly normal phenotypes or had minor congenital malformations. Conclusion : Early diagnoses of sex chromosome abnormalities is required to prevent associated morbidities and to maximize growth and development. We have to pay careful attention in diagnoses of Turner syndrome because of the high proportion of mosaicism and structural aberrations.

The purpose of this study was to examine the relationship between maternal age and infant mortality in Korea(n=617,867). Data of Korean vital statistics linked National Infant Mortality Survey conducted on births in 1999 were used in this study. The odds ratios (ORs) of infant death by maternal age were estimated with the multiple logistic regression model, adjusting for gender, plurality, birth order, low birth weight, and congenital malformation. After adjusting for the relevant variables, the odds of infant death in the group of maternal age with less than 20 years(Odds ratio [OR], 5.29, 95% confidence interval [CI], 3.51-7.98), 20-24 years(OR, 1.44, 95% CI, 1.23-1.69), 35-39 years(OR, 1.28, 95% CI, 1.11-1.46), and more than 40 years(OR, 1.94, 95% CI, 1.53-2.45) was higher than that of reference group(25-29 years). In conclusion, the higher infant mortality in the group of maternal age with less than 25 years and more than 35 years in Korea appears to be due to higher proportion of low birth weight and pre-term birth. Prenatal care intervention programs which tackle biological factors for advanced maternal age and address socio-economic problems and social stigma for early maternal age should be devised.

Ebsteins anomaly is a rare congenital cardiac malformation that is the downward displacement of the septal and posterior leaflets of the tricuspid valve into the ventricular apex, aresulting in the formation of an atrialized portion of the right ventricle. In most patients, symptoms such as cyanosis and progressive heart failure occur during the adolescence or young adulthood. The associated anomalies include ventricular septal defect, transposition of the great arteries, and malformation of the mitral valve. An 8-months-old male with Ebsteins anomaly, ventricular septal defect, and duplication of the mitral valve orifice successfully underwent operation with VSD patch closure. Postoperatively, cardiac size was significantly reduced and tricuspid regurgitation was trivial in echocardiography He has been doing well without any cardiac medication during the 18 months follow up after operation.

The bulging of mandibular angle area, frequently, make some difficulties in social life due to its reckless appearence, especially in oriental nations. So, many authors had reported its causes and surgical techniques for correction since late 19th century with diagnosis of masseter hypertrophy. But in spite of its muscular origin, major surgical techniques, in general, should aim complete bony reduction or osteotomy and supplemental myotomy as in hemimandibular hypertrophy or mandibular elongation. We used ultrasonogram for soft tissue depth estimation and expearenced some complications such as incomplete lingual cortical bony reduction, condylar fracture in mandibular angle reduction via intraoral circumvestibular approach. So we reported our surgical technique for angle reduction with possible complications.
