Background & object : Generally, blood spots of newborn have been sent to the 2n d institution for differential confirmatory test, who showed positive through newborn screening for galactosemia. So far no report on the investigative analyses on confirmatory test results of positive Galactosemia results of newborn blood spots, who have been born in General Hospital. We have investigated the proportion of blood spotsamples that gave positive screen results of newborn blood spots born in Soonchynhyang University Hospital. Methods: We investigated and analyzed through examining medical records of newborns who were born or transferred in Soonchunhyang University Hospital in 2009. Newborn born blood spots obtained were from what was transferred to our Hospital for confirmatory tests or from what was visited to our Hospital for the total galactose, free galactose, galactose-1-phosphate, and Beutler tests. Results : Out of 252 newborns who received secondary confirmatory tests, the newborn blood spots who showed abnormal was as follows; 66 (26.2%) for total galactose, 10 (4.0%) for free galactose, 32 (12.7%) for galactose-1-phosphate and, 0 for Beutler tests. Among 96 newborns who have seen attending physician 18 (19.1 %) showed abnormal, and finally 5 (2.0%) was diagnosed as Galactosemia and 15 was transient Galactosemia. Out of 18 newborns who have been transferred to secondary confirmatory test 3 have been diagnosed as Galactosemia. Finally five (2.0%) was diagnosed as Galac tosemia out of 252 born at Soonchunhyang University Hospital in 2009. From these results we expect there might be more than 7 newborns with Galactosemia, though 7 Galactosemia newborn patients have already been registered at community health center. Conclusions : For the prevention of mental retardation and effective therapy over Galactosemia, secondary confirmatory test ought to be performed right away if the result of newborn screening for Galactosemia is positive. 갈락토오스혈증은 갈락토오스 분해효소의 결핍으로 인하여 섭취한 갈락토오스를 우리 몸에서 에너지 원으로 이용되는 포도당으로 바꾸지 못하여 체내에 갈락토오스가 축적되는 유전성 질환으로 신생아 시기에 치료하지 않으면 발육부전 및 정신지체가 발생 하고 심한 경우 사망하기도 한다. 신생아 때 발견하여 치료하면 정신지체를 예방할 수 있는 유전성 대사질환에 대한 신생아 선별검사가 1985년 국내에 처음 도입된 이후 갈락토오스혈증에 대한 신생아 선별검사가 2006년부터 정부 지원사업으로 채택되어 모든 신생아를 대상으로 무료로 실시되고 있다. 갈락토오스혈증에 대한 선생아 선별검사가 시작된 이후 양성자들에 대한 확인검사를 통하여 갈락토오스혈증 환자가 진단되고 있지만 아직까지 우리나라에서의 발생빈도는 정확히 알 수 없다. 신생아 선별검사에서 갈락토오스혈중 양성인 신생아들은 확인검사 기관에서 정밀검사를 받지만 검밀검사에서 진단된 환아가 얼마나 되는지 정확히 알 수 없고, 진단된 환아 중 몇 명이 보건소에 동록되는지 알 수 없다. 확인검사를 통하여 진단된 환아 중 보건소에 사후관리자로 등록된 환자를 근거로 산출한 2006부터 2009년까지 4년간 갈락토오스혈증의 발생빈도는 51,419명당 1 명이다. 최태윤 등은 2005년도 신생아 선별검사결과를 근거로 산출한 갈락토오스혈증 발생 빈도가 39,314명당 1명으로 보고하였다. 저자들은 갈락토오스혈증에 대한 신생아 선별검사에서 양성인 신생아 중 확인검사를 받기 위하여 정밀검사 기관으로 내원한 신생아들 대상으로 확인검사 결과를 실시하고 그 결과를 분석하여 보고하는 바이다.

최태윤 대한감염학회 1995 감염 Vol.27 No.3

목적:1994년 9월 구미 공단내의 한 회사에서 야간 근로자들이 야식을 먹고 집단 식중독이 발생하여 역학조사와 함께 원인을 규명하였다. 방법:식중독의 원인균과 감염원을 규명하기 위하여 환자의 대변과 음식물을 수거하여 배양검사를 실시하였으며, 환자의 의무기록지를 분석하였다. 결과 1) 발병 환자는 총 79명으로 남자 14명, 여자 65명이었다. 2) 발병기간은 음식을 먹은 후 12시간 이내가 19명(24%), 12-24시간이 52명(66%), 24-48시간이 8명(10%)이었다. 3) 수반된 증상은 복통(91%), 물설사(86%), 발열 및 오한(75%), 구역 및 구토(68%), 두통(51%) 등이었다. 4) 평균 백혈구수는 10,770/㎕(4,600-18,700/㎕)으로 5,000/㎕ 미만이 2%, 5,000-10,000/㎕가 45%, 10,000-15,000/㎕가 43%, 15,000/㎕ 이상이 10%이었으며, 환자의 86%에서 중성구가 80% 이상이었다. 5) 대변배양검사를 실시한 35명중 34명에서 S. enteritidis가 분리되었다. 6) 음식물에 대한 배양검사에서 김밥에서 S. enteritidis가 분리되었다. 7) 대부분의 환자는 수액요법과 약처방으로 당일 퇴원하였고, 12명(15%)은 입원치료후 퇴원하였다. 결론:한 회사내에서 발생한 집단 식중독의 원인을 규명한 결과 S. enteritidis에 오염된 김밥으로 인하여 79명의 환자가 발생하였다 산업장에서 집단 식중독이 발생하면 노동력이 저하되므로 집단급식을 하는 곳에서는 식품 위생을 철저히 지켜야 하며, 비장티푸스성 Salmonella 감염증도 법정 전염병으로 정하여 국가에서 관리해야 할 것으로 사료되는 바이다. Background: On September 1994, an outbreak of food poisoning occurred among employees of a factory in Kumi. Patients were visited in Soonchunhyang Kumi hospital. This report contains results of an epidemiological investigation of the outbreak. Methods: Stool culture was performed in 35 of 79 patients with food poisoning and the foods, which patients had eaten, were cultured. The medical records of 79 patients with food poisoning were reviewed retrospectively. Results: 1) 79 patients(male 14, female 65) were visited in the hospital. 2) The incubation period was less than 12 hours in 24%, 12-24 hours in 66%, and 24-48 hours in 10%. 3) Predominant symptoms were abdominal pain(91%), watery diarrhea(86%), fever/chilling(75%), nausea/vomiting(68%) and headache(51%). 4) Mean leukocyte count was 10,770/㎕(4,600-18,700/㎕). 5) Salmonella enteritidis was isolated from stool in 34 of 35 patients who submitted specimens. 6) Salmonella enteritidis was isolated from the seaweed roll which patients had eaten. 7) On the visited day, 67 ill patients were discharged after intravenous rehydration and oral medication; twelve were hospitalized. Conclusion: An outbreak of Salmonella enteritidis infection associated with food occurred among employees of a factory in Kumi on September 1994. 79 patients were affected. Good hygiene of the cooking personnel and adequate cooking of foods are necessary in controlling such outbreaks of nontyphoidal salmonellosis among factory workers.

Background & object : Congenital adrenal hyperplasia (CAH) is difficult to detect in early stages. Failure to diagnose it in the initial state may lead to life-threatening adrenal crisis, inappropriate male sex assignment in the genetic female, acceleration of skeletal maturation and subsequent short stature. The importance of the neonatal screening test is being emphasized, but the reference values different according to laboratories and test reagents. The object of this study is to set appropriate reference ranges of 17-hydroxyprogesterone (17-OHP) neonatal screening test for congenital adrenal hyperplasia according to the test reagents and analyze reference range applied in each laboratory. Methods : Neonatal screening test was performed by enzyme immunoassay for 17-OHP using the collected dry bloods drawn out the capillaries of 500 neonate heels from 48 hours after birth to 1 week, for which the mass screening tests on inborn errors of metabolism were requested from January 2003 to August 2003 at the Soonchunhyang University Hospital. The measurement of 17-OHP was performed by ICN Neoscreen ELISA 17a-hydroxyprogesterone kit (ICN Pharmaceuticals. Inc., USA), Enzaplate 17-OHP kit (Bayer Diagnostic Ltd., Japan) and Microplate Neonatal 17-OHP kit (Bio-Rad Laboratories, USA). Reference values of 17-OHP neonatal screening test according to the test reagents were analyzed in the 500 newborns. Results : The mean value ± standard deviation (SD) of 17-OHP using ICN, Bayer and Bio-Rad reagents were 8.14±5.33 ng/mL, 4.74±2.00 ng/mL and 1.80±1.82 ng/mL, respectively. The mean value of 17-OHP was significantly different between test reagents (P<0.05). The 99% & mean±3SD reference ranges of 17-OHP using ICN, Bayer and Bio-Rad reagents were 0-22.99 & 0-24.13 ng/mL, 0-12.30 & 0-10.74 ng/mL and 0-7.85 & 7.22 ng/mL, respectively. Although same test reagents were used in laboratories, the applied reference ranges were various. Conclusions : The reference ranges of 17-OHP neonatal screening test for congenital adrenal hyperplasia were various according to laboratories and test reagents. It is better to establish an appropriate reference range of each reagent under the intensive quality control.

최태윤,윤혜란 덕성여자대학교 약학연구소 2009 藥學論文誌 Vol.20 No.-

Hepatitis A occurs in 60-90% of people, mainly in children, adolescence, and adult, if exposed to the contagion hepatitis A virus (HAV) because it is highly susceptible. In the first half of the year 2009, symptomatic hepatitis A causing severe clinical manifestations has increased dramatically. Therefore we tried to evaluate the seroprevalence of hepatitis A virus and hepatitis A patients according to age and month. From July 2008 to August 2009, anti-HAV IgG and IgM antibody tests were conducted using the MEIA method by Abbott AXSYM equipment at the department of laboratory medicine, Soonchunhyang University Hospital. We retrospectively evaluated seropositivity of anti-HAY IgG antibody according to age. Also we retrospectively evaluated the characteristics of hepatitis A positive patient according to month. The positive rate of anti - HAV IgG test was 66% of total 1,316 peoples. Antibody positive rate was 67 % in aged 0-9 years, 30% in aged 10-19 years, 36% in aged 20-29 years, 54% in aged 30-39 years, 91% in aged 40-49 years, 99% in aged 50-59 years, 99% in aged 60-69 years, and 100% in aged more than 70 years. Patients diagnosed with hepatitis A was 217 (23%) in total of 962 peoples whose anti-HAY IgM antibody tests requested. The prevalence of the patient by age was 0.5% in aged 0-9 years, 3.7% in aged 10-19 years, 38.7% in aged 20-29 years, 43.8% in aged 30-39 years, 12.4% in aged 40-49 years, 0.5% in aged 50-59 years, 0.0% in aged 60-69 years, and 0.5% in aged more than 70 years. The number of patient by month was 4-7 from July 2008 to February 2009, then started to increase 17 from March 2009 and the highest number increase from April to June. After then the number of patients gradually began to reduce. The spread of hepatitis A has started spring of this year in July the occurrence of it has been reduced owing to the promotion of hand washing for preventing swine flu. Since patients with hepatitis A in their twenties and thirties accounted for more than 80% of the total patients with hepatitis A, for convenience, vaccination is performed without antibody test in their twenties and thirties showing low antibody retention rate. If they are older age than in their thirties. in case of absence of antibody vaccination is necessary with antibody test.
