송경일(Kyung-Il Song),장중순(Joong-Soon Jang) 한국신뢰성학회 2014 신뢰성응용연구 Vol.14 No.2

The demand against the risk analysis and information security of system from the companies or the agencies which operate an information system is increasing. ISO/IEC 27001 was established by ISO (International Organization for Standardization) and IEC (International Electrotechnical Commission). Also this standard is international and authoritative standard of ISMS (Information Security Management System). This paper is to review how the ISO 27001 ISMS Requirement has been established and improved, and to communicate the significant changes from ISO27001 : 2005 to ISO 27001 : 2013 focusing on reasons for revisions. Additionally, This paper shows case study for understanding ISO 27001 : 2013 implementation.

목적 : 고령에서 혈액투석을 시작한 환자들의 생존율, 사망 원인, 사망에 관계되는 위험 인자및 기술생존율을 알아보고자 본 연구를 시행하였다. 방법 : 1996년 8월부터 2001년 7월까지 5년 동안, 강릉아산병원에서 70세 이상 나이에서 혈액투석을 시작한 환자들 중 최소 3개월 이상 추적 가능한 34명을 대상으로 환자들의 생존율, 사망 원인, 사망에 관계되는 위험 인자 및 기술생존율을 조사하였다. 사망에 관계되는 위험 인자로 성별, 당뇨병 유무, 혈액투석 시작 시점의 나이 및 혈액 검사 소견을 분석하였다. 결과 : 처음 혈액투석을 시작한 최고 연령은 85세였고 중앙값은 74.5세였으며 남녀 비는 2.4:1이었다. 추적기간은 4개월에서 52개월로 평균 추적기간은 18.6±2.5개월이었다. 말기신부전의 원인으로는 당뇨병이 12명 (35.5%)으로 가장 많았고 사인으로는 심혈관질환이 3명 (37.5%)으로 가장 많았다. 대상 환자 34명의 최종 추적결과 21명 (61.8%)이 혈액투석을 지속했고 8명 (23.5%)은 사망, 1명(2.9%)은 복막투석으로 전환하였고 4명 (11.8%)은 추적 탈락되었고 이식을 받은 환자는 없었다. 대상 환자 34명의 1, 2, 5년 생존율은 각각 84.9, 72.8, 56.6%였다. 전체 환자의 기술생존율은 1, 2 4년에 각각 54.7, 48.6, 30.1%였고 동정맥루와 인조혈관 사이의 기술생존율은 차이가 없었다. (p-0.08). Cox regression hazard model을 이용한 다변량 분석 결과 사망을 예측하는 지표는 투석 시작 당시의 나이 (RR=1.685, p=0.018) 여성 (RR=18.5 P=0.028), 투석 시작 시 헤모글로빈 수치 (RR=0.233, p=0.009)가 통계적으로 의미가 있었고 알부민, 크레아티닌, 콜레스테롤, 당뇨병의 유무는 생존율에 유의한 의미는 없었다. 결론 : 고령에서 혈액투석을 시작한 환자들의 1, 5년 생존율은 84.9%, 56.6%이고 기술생존율은 1, 4년에 각각 54.7, 30.1%였다. 심혈관계 질환이 중요 사인이었고 투석 시작 당시의 나이, 성별, 헤모글로빈 수치가 사망의 중요 위험 인자임을 알 수 있었다. Purpose : The increased prevalence and incidence of end-stage renal disease (ESRD) in the elderly has become a worldwide phenomenon. New cases of ESRD are growing faster among people aged older than 70 years. We studied in order to investigate the survival rate, technical survival rate, causes of death and the predictors of death in patient starting hemodialysis aged over 70 years. Methods : We analyze 34 patients who started hemodialysis as an initial replacement therapy for chronic renal failure in Kangnung Asan Hospital between July 1996 and July 2001. Demographic and clinical characteristics, including diabetes mellitus and laboratory findings at the beginning of hemodialsis were retrospectively analyzed. All subjects were followed up until the point of assessment, the time of death or withdrawal from dialysis. The survival rate was calculated by Kaplan-Meier method. In order to determine independent predictors of death, we used Cox proportional hazard model. Results : The median age of thepatients was 74.5 years and sex ratio was 2.4:1 (M:F). The most common cause of ESRD was diabetes (35.5%) and obstructive uropathy was second. The mean followup period was 18.6±2.5 months and cardiac problems were major causes of death (37.5%). The survival rate of 34 patients was 84.9% at 1 year, 72.8% at 2 year and 56.6% at 5 years. The technical survival rate of 34 patients was 54.7% at 1 year, 48.6% at 2 year and 30.1% at 4 years. The predictors of death were found to be (ⅰ) age starting hemodialysis (RR=1.685, p=0.018) (ⅱ) female (RR=18.5, P=0.028) (ⅲ) low initial hemoglobin level (RR 0.233, p=0.009). Conclusion : Very elderly ESRD patients on dialysis have a relatively good outcome and age is not barrier to dialysis. Measures to improve quality of life of elderly hemodialysis patients may favorably influence their survival.

목적: 신전손상에 의한 하경추부 외상에서 연부조직의 손상을 MRI로 분류하여 신전손상의 정도를 진단하고 또한 연부조직 손상 정도와 척수 손상의 발생이 관계가 있는지 알아보고자 하였다. 대상 및 방법: 최근 5년간 하경추부 신연-신전손상으로 진단되어 치료를 받은 81명을 대상으로 하였다. 모든 환자에서 술 전 MRI를 촬영하였으며 연부조직 손상의 정도를 5단계로 세부 분류하였다. 결과: 후종 인대 파열이 동반된 3단계 이상의 연부조직 손상에서 척수 손상이 발생되었다(p<0.01). 척수 신호 강도의 변화도 연부조직 손상 단계가 증가할수록 많이 발생하였다(p<0.01). 척추관 협착증 환자에서 연부조직 손상과 척수 손상과는 관계가 없었다(p=0.45). 결론: 하경추부 신연-신전 손상에서 자기공명영상은 연부조직 손상의 정도를 정확하게 진단할 수 있었으며 연부조직 손상의 정도와 척수손상의 발생은 밀접한 관계가 있음을 알 수 있었다. Purpose: To diagnose the extent of soft tissue damage with MRI, and to evaluate the relationship between soft tissue damage and a spinal cord injury in an extension injury to the lower cervical spine trauma. Materials and Methods: Eighty-one patients who treated surgically for an anextension injury to the cervical spine over the past 5 years, were analyzed. All patients had undergone MRI after the injury, and for the specific grading of soft tissue damage, the grades were defined from grades 1 to 5. Results: The spinal cord injury developed with more than grade 3 soft tissue damage associated with a rupture of the posterior longitudinal ligament (p<0.01). The changes in signal intensity of the spinal cord also developed according to the severity of soft tissue damage (p<0.01). There was no relationship between the soft tissue damage and the spinal cord injury in spinal stenosis (p=0.75). Conclusion: The extent of soft tissue damage was diagnosed precisely with MRI, and there was an close relationship between the soft tissue damage and spinal cord injury in the distractive-extension injury to the lower cervical spine trauma.

식도협착과 급성신부전이 합병된 개미산 중독 1례

송경일,Song, Kyung-Il 대한임상독성학회 2009 대한임상독성학회지 Vol.7 No.1

Formic acid or formate is a common industrial compound used in the production of ensilage, disinfectants, decalcifying agents and mainly as a precursor in industrial chemical synthesis. It is also a well-known toxic metabolite produced in methanol poisoning. Thus, formate is a potential source of both accidental and deliberate poisoning. Very few reports have been published thus far, on the toxicology of direct formic acid poisoning. Here, we report a case of a 74-year-old man without a history of depression, who ingested about 30 gm of formic acid. The patient presented with profound high anion gap metabolic acidosis, acute renal failure and esophageal stricture. The patient was successfully treated with hemodialysis and supportive measures. But permanent esophageal stricture was complicated by formic acid burns in the gastrointestinal tract. We discuss the pathophysiology and treatment of this case.

N/A No one test will provide unequivocal answer to the questions about the acute pancreatitis such as How severe is the disease? Are complications present?, What is the prognosis?. But the use of clinical, laboratory and imaging findings often enables the clinician to estabilish a diagnosis, identify complications and predict the prognosis. From April 1983, to December 1987, 6 patients with surgically documented necrotizing pancreatitis at Chun An Soon Chun Hyang Hospital were retrospectively analyzed. 1) The patients, who were surgically proven necrotizing pancreatitis, were 4 men and 2 women ranging in age from 27 to 70 years(mean: 54.7). 2) The possible etiological factors were alcohol abuse in 2, gallstone in 1 and idiopathic in 3 patients. 3) In the clinical and laboratory findings, the majority of the patients showed peritoneal irritation sign, leukocytosis, increased base dificit and decreased serum calcium levels. 4) Based on Ransons ll criteria for the severity of acute pancreatitis, the patients in this study were classified as moderate to severe group. 5) CT scans were more excellent than ultrasonography in demonstrating pancreatic necrosis and intraabdominal extension of inflammatory process. 6) Favorable results(mortality: 17%) could be obtained by early necrosectomy and peritoneal lavage in the management of necrotizing pancreatitis. In conclusion, a combination of CT findings and Ransons prognostic signs will result in more accurate and early identification of high risk of necrotizing pancreatitis.

저자들은 B형 간염에 의한 간경화가 있는 혈액투석 환자에서 반복적인 복수 및 복막염의 증상이 발생하여 경화성복막염 의심하에 개복술로 이를 확진하였고 이후 스테로이드 치료로 호전된 경화성 피막성 복막염을 1예를 경험하였기에 문헌고찰과 함께 보고하는 바이다. Encapsulating peritoneal fibrosis (EPF) is a serious, uncommon complication of chronic peritoneal dialysis. However, it is rare in hemodialysis patients. EPF is characterized by peritoneal membrane inflammation followed by peritoneal membrane fibrosis and encapsulation. The etiology is unclear, but inflammation of the deteriorated peritoneum causes peritoneal fibrosis. We present a case of EPF that occurred in a 29-year-old man with hepatitis B-associated liver cirrhosis with ascites that was treated solely with hemodialysis. We managed this patient surgically and then medically with prednisolone. To our knowledge, this is the first such case in Korea, so we report this case with a literature review.
