감염성심내막염에 의한 신경계 합병증은 색전성 뇌경색, 색전성 뇌출혈, 두개내 패혈성 동맥류, 뇌농양, 뇌막염등 다양한데 항생제 요법의 발달과 판막치환술에도 불구하고 그 빈도는 감소되지 않고 있다. 이 중 두개내 패혈성 동맥류의 파열에 의한 뇌출혈은 사망률이 80%로 치명적일 수 있어 조기 발견 및 적절한 치료가 필요하다. 저자들은 두통, 열감, 근육통 등의 증상으로 내원하여 감염성 심내막염으로 진단받고, 항생제 치료로 임상증세의 호전중에 심한 두통과 전신적 발작이 있은 후 갑자기 발생한 두개내 뇌출혈을 심장초음파 및 뇌 컴퓨터 단층촬영을 통하여 진단, 경험하였기에 문헌고찰과 함께 보고하는 바이다. The complications of infective endocarditis may involve any organ system ie, cardia, neurologic, vascular, dermatologic, and kidney. Extracardiac complications are usually caused by either embolization of vegetations or deposition of immune complexes. Neurologic complications remain a significant problem in bacterial endocarditis and have been reported to occur in up to 20% to 40% of cases of infective endocarditis. The various types of central nervous system disease seen in patients with infective endocarditis are cerebral embolism (with infarction or with intracerebral hemorrhage), intracranial mycotic aneurysm, seizures, brain abscess, meningitis, mental change, psychiatric disorder. Mycotic aneurysms are uncommon but not rare and are an important cause of local or systemic sepsis and acute hemorrhage following aneurysmal rupture. Cerebral mycotic aneurysms have been noted in 2∼10% of cases of bacterial endocarditis and account for 2.5∼6.2% of all intracerebral aneurysms. We have experienced a case of neurologic complication due to infective endocarditis in a 23 year-old female patient, who admitted to our hospital because of fever, chill, headache, myalgia. This case was diagnosed by echocardiography, brain computed tomography. The patient died of sudden intracerebral hemorrhage in the 53th hospital day despite intensive medical treatment. We report one case of intracerebral hemorrhage complicated with infective endocarditis.

In past decade, ectopic pregnancy developing in the previous cesarean section scar has been the rarest forms of ectopic pregnancy and very dangerous because of the risk of uterine rupture and hemorrhage. These pregnancies once carried a maternal mortality rate of 40% to 45%, and until recent years they usually resulted in abdominal hysterectomy as a life-saving procedure. However, increased awareness of the importance of preserving childbearing capacity has led to several successful attempts at conservative management that include intraamniotic and systemic methotrexate administration, suction curettage followed by insertion of an intracervical 30-mL Foley catheter ballooning and angiographic artery embolization. We present three cases of ectopic pregnancy developing in the previous cesarean section scar in which successfully treated with conservative management.

박동건,이정남 朝鮮大學校 附設 醫學硏究所 1986 The Medical Journal of Chosun University Vol.11 No.1

In order to evaluate the frequency of extrapyramidal symptoms induced by long-acting oral antipsychotics, Penfluridal, 48 chronic schizophrenics were subjected in this study. Schizophrenic patients were divided into group A(N=26, 1 week neuroleptics washout periord) and group B (N-22, neuroleptics nonwashout period). Penfluridol of 20 to 100㎎ was administered, racing of exfrapyramidal symptoms was measured by the Rating Scale for Extrapyramidal Symptoms designed by Chien and Dimascio at the interval of 1,2,3,4,5, and 6 week. The results are as follows. 1. Dropout rate due to severe extrapyramidal symptoms was noticed in 6 out of the 48 cases(12.5%). 2. Most common period of occurence of extrapyramidal symptoms in group A is revealed at the 6th week(33.3%) and that in group B is noted at the 3rd week(40.9%) 3. To control extrapyramidal symptoms, when benztropine mesylate was administered orally, the mean days of administration in group A were 21.22±8.45 and those in group B were 11.63±2.50. This difference of mean days between group A and B was highly significant(P < 0.005). In. conclusion, to minimize extrapyramidal symptoms, it is recommended to start the regimen with drug washout period in converting previous antipsychotics medication into penfluridol.

국내 호중구감소성 발열 환자에게 경험적 항진균제로 투여한 Amphotericin B deoxycholate와 Itraconazole 주사제의 비용-확인분석 : 예비보고

이동건,송영구,유진홍,최수미,최정현,박선희,신완식 대한감염학회 2004 감염과 화학요법 Vol.36 No.5

목적 : 진균감염이 점차 증가되고 있고 이를 치료하기 위한 비용 역시 증가하고 있지만 국내에서는 비용분석에 대한 연구가 거의 없는 실정이다. 본 연구에서는 호중구감소성 발열 환자에게 경험적 항진균제로 amphotericin B deoxycholate (ABV)혹은 정맥내 itraconazole (ITZA)을 투여할 때의 약물경제학적 측면을 후향적으로 비교해보고자 하였다. 재료 및 방법 : 같은 반응률을 보인다고 가정한 비용-확인분석 모델을 이용하여 가톨릭대학교 조혈모세포이식센터에서 혈액종양으로 항암치료 혹은 조혈모세포이식을 시행한 환자를 대상으로 자료를 수집하였다. 항진균제 투여에 대한 정보는 기존에 출판된 논문 및 학회 심포지움자료를 참고하였고, 논문에서 얻지 못한 정보는 가톨릭대학교 성모병원 의무기록실, 정보지원팀, 진료비관리팀의 협조를 받아 2003년 6월 1일부터 11월 30일까지의 자료를 분석하였다. ITZA에 대한 자료는 2003년 11월 제한적으로 1차 약제로 사용할 수 있게 되었던 때의 자료와 경험을 참조하였다. 결과 : 320명의 환자 중 149명(46.5%)에서 경험적 항진균제를 사용하였고 평균 투여일수는 ABV 17.0일, ITZA 9.8일이었다. 이상반응 발현율은 ABV 54%, ITZA 5%였다. ABV 투여환자 중 11명 (7.4%)에서 혈액투석을 평균 6.5일간 시행하였다. ITZA 투여시 간독성으로 혈장분리반출술, 인공간 등이 필요한 경우는 없었다. 경험적 항진균제를 ABV로 시작한 군(ABV군)은 1인당 1,229,495원, ITZA로 시작한 군(ITZA군)은 1인당 1,434,605원이 소요되어 ITZA군에서 205,110원 (16.7%)이 더 소요되었다. 평균 16일간 항진균제를 사용하여 1일 12,819.4원의 차이가 있었다. 결론 : 비용-확인 분석법에서 ITZA군이 ABV군 비해 하루 12,819.4원의 비용이 더 소요되었다. 비록 ITZA군에서 비용이 더 들었지만 1일 약가차이인 4.7배와 비교하여 많이 감소하여 항진균제의 비용을 1일 약가로 비교하는 것보다는 재원일수, 이상반응 발현율 등을 고려하는 총입원비용으로 약물경제학을 비교하는 것이 더 합당할 것으로 사료된다. 그 외에 환자의 예후, 삶의 질, 사회적 간접비용 등을 고려하는 전체적인 약물경제학을 비교하는 잘 계획된 전향적 연구가 추가로 필요하겠다. Background : The increasing incidence of systemic fungal infections and the rising medical cost have focused the need to determine the economic issues of antifungal agents. Nevertheless there have been only few reports about the cost analysis in Korea. We retrospectively investigated to compare the pharmacoeconomic aspects of amphotericin B deoxycholate (ABV) with those of intravenous itraconazole (ITZA) in the empirical treatment of febrile neutropenic patients. Materials and Methods : Through the cost-identification analysis model, on the presumption that two groups would show identical response, we collected data of patients who received hematopoietic stem cell transplantation (HSCT) or chemotherapy in Catholic HSCT center from Jun 1, 2003 to Nov 30, 2003. The literatures about information on antifungal therapy were extensively reviewed. Other unpublished information was provided by information assistant team, cost management team, and medical record unit in the same hospital. Results : Empirical antifungals were given to 149 out of 320 patients (46.5%). The average duration of administration were 17.0 days for ABV and 9.8 days for ITZA. The rates of adverse events were 54% and 5% for ABV and ITZA, respectively. Eleven (7.4%) patients given ABV received hemodialysis for 6.5 days in average. Among patients given ITZA, none developed hepatotoxicity requiring plasmapheresis or artificial liver. It cost 1,229,495 won/patient for the ABV group (starting ABV as empirical antifungal agent) and 1,434,605 won/patient for the ITZA group (starting ITZA as empirical antifungal agent) which was 16.7% more expensive than ABV group. When we compare the average daily cost for 16 days, the ITZA group spent 12,819.4 won/patient/day more than the ABV group. Conclusion : The cost-identification model in this study revealed that ITZA group cost more than ABV group. However, the difference in expense decreased when 1 day-cost was compared (4.7 times greater than ABV). It would be more reasonable to consider the total cost of anti-fungals during the hospitalization rather than 1 day cost in considering pharmacoeconomics. Well designed prospective study considering prognosis of patients, quality of life, and indirect social cost should be warranted.
