양신석,김영욱,박양진,김동익,우신영,허승,김형기 대한혈관외과학회 2014 Vascular Specialist International Vol.30 No.3

Purpose: The aim of study was to review the results of open surgical repair (OSR) of chronic juxtarenal aortic occlusion (JRAO). Materials and Methods: We retrospectively reviewed the results of OSR performed in 47 patients (male, 92%; mean age, 59.9±9.3 years [range, 44-79]) with chronic JRAO during the past 21 years. In order to reduce intraoperative renal ischemic time (RIT), we excised a portion of the occluded segment of the infrarenal aorta without proximal aortic clamping. We then performed suprarenal aortic clamping with both renal arteries clamped, removed the proximal aortic thrombus cap, confirmed both renal artery orifices, and moved the suprarenal aortic clamp to the infrarenal aorta to allow renal perfusion and standard aortoiliac reconstruction. We investigated early (<30 days) postoperative surgical morbidity (particularly renal function), operative mortality, and longterm patient survival. We conducted risk factor analysis for postoperative renal insufficiency. Results: The mean intraoperative RIT was 10.7±5.5 minutes (range, 3-25), including 6 patients who underwent concomitant pararenal aortic thromboendarterectomy. Postoperatively, five (11%) patients had transient renal insufficiency, one had pneumonia, and one patient had an acute myocardial infarction. However, there was no operative mortality or newly developed dialysis-dependent renal failure. Postoperative follow up was available in 36 (77%) patients for a mean period of 6.3 years (range, 1 month-17 years). Kaplan Meier calculations of patient survival at 5 and 10 years after surgery were 91.2% and 83.6%, respectively. Conclusion: We have experienced short RIT, acceptable early postoperative results and long-term survival after OSR of chronic JRAO.

인체기생 열두조충류의 형태비교 및 진단적 소견

임신영,강성구,양용상,백승한,류장근 THE KOREAN SOCIETY FOR BIOMEDICAL LABORATORY SCIEN 1998 Journal of biomedical laboratory sciences Vol.4 No.1

최근 우리 나라는 열두조충과 (Diphyllobothridae)에 속하는 조충류의 인체 감염예가 빈번하게 보고되고 있다. 이는 본 조충류의 감염매체인 어류를 날 것으로 생식할 기회가 많으며, 또한 본 조충류의 제1중간숙주인 물벼룩이 음료수를 통한 인체 감염이 원인일 것으로 추정되고 있다. 조충류의 진단은 충체에 있어 두적과 편절의 형태학적 특징을 감별하여 種의 분류와 진단을 하는 것이 기본적 순서가 될 것이나, 1차적으로 가능한 진단은 환자의 증상 참작과 분변으로부터 충란을 발견 감별하게 된다. 특히 광절열두조충류의 충란에 의한 種鑑別은 환자로부터 편절이나 충체의 확실한 감별을 위한 사전 정보를 가늠하는 뜻에서도 중요성이 있다. 이에 저자들은 환자의 치료와 함께 수집된 Diphyllobothrium latum, D. latum parvum 그리고 Spirometra erinacei의 편절과 충란을 재료로 형태 및 진단적 결과를 분석한 바 그 성적은 다음과 같다. 1. 환자의 분변에서 수집된 충란 50개씩을 각각 선택하여 형태와 크기에 대한 계측을 실시하였다. D. latum의 충란은 난개가 있고 난원형 또는 타원형의 모양으로 관찰되었으며 D. latum parvum은 D. latum에 비하여 더 난원형이면서 작게 관찰되었다. S. erinacei의 충란은 폭이 비대칭적이며 길쭉한 모양으로 관찰되었다. 2. D. latum, D. latum parvum 그리고 S. erinacei의 충란의 크기에서 충란의 평균 길이와 폭은 각각 61.4X41.7㎛, 55.9X41.4㎛ 그리고 66.7X36.4㎛이었다. 3. 각 조충의 편절을 고정한 다음, 첫째 포매하고 microtome으로 절편을 만들어 hematoxylin-eosin 염색을 실시하였고, 둘째 고정과 함께 semicon's aceto-carmine 염색표본을 작성하여 현미경 관찰을 한 결과 D. latum과 D. latum parvum은 생식선이 편절의 중앙선상에 위치하고 개구된 자궁구가 관찰되었다. 그리고 편절의 양측에 난황이 follicle로 관찰되었으며 전형적인 rosette모양을 형성하고 있었다. 그러나 D. latum parvum은 D. latum에 비하여 아주 작은 크기로 관찰되었다. S. erinacei의 편절은 자궁이 나선형으로 5∼7회 이상으로 말려서 관찰되었고 음경낭안에서 저정낭이 이어져 연결되고 있었다. 이로써 본 연구에서는 편절의 형태특징과 함께 충란 크기에 대한 계측과 분석을 하고자 하였으며, 공학현미경에 의한 계측치로 세 종류의 조충 감별에 유의한 참고치를 제기하는 바이다. Recently there have been frequent reports on human infection caused by the Diphyllobothridae in Korea. The adequate opportunities for Koreans to eat raw fish, the primary infection medium of cestodes and the human infection through drinking water by cyclops, the first intermediate host are believed to be main reasons for the infection. The first task of this study was to classify and diagnose the species by differentiating morphological characteristic between scolex and proglottids of cestodes. However, the initially available diagnosis was done with the patient's symptoms and the eggs obtained from his stool. It is important to differentiate the species by the eggs of Diphyllobothrium latum especially in that it can help get advance information for a more reliable analysis in the near future. The morphological and diagnostic results from proglottids and eggs of Diphyllobothrium latum, Diphyllobothrium latum parvum and Spirometra erinacei are as follows; In each kind of cestodes from the patient's stool, the shape and size of 50 eggs were measured. Eggs of Diphyllobothrium latum had an operculum and were ovoidal or ellipsoid to elliptical in shape. Eggs of Diphyllobothrium latum parvum were more ovoidal in shape and smaller in size than Diphyllobothrium latum. And eggs of Spirometra erinacei were asymmetrical in width and long and slender in shape. The average lengths and widths of Diphyllobothrium latum, Diphyllobothrium latum parvum and Spirometra erinacei were 61.4X41.7㎛, 55.9X41.4㎛ and 66.7X36.4㎛, respectively. After the segments of each cestode were fixed, embedding and hematoxylin-eosin dyeing on a microtome-made specimen were done. The micrographs of the semicon's aceto-carmine dyed specimen showed that Diphyllobothrium latum and Diphyllobothrium latum parvum had a centrally-located genital gland and an opened uterine pore. The yolks were observed on both sides of proglottids and had a typical rosette pattern. Yet, Diphyllobothrium latum parvum was shown smaller than Diphyllobothrium latum in the micrograph. Proglottids of Spirometra erinacei displayed that the uterus was rolled spirally more than five to seven times, and connected successively to the seminal vesicle in the cirrus sac. Shown above, this study was performed to measure the size of eggs and analyze the morphological characteristics of proglottids and provided the measurements of three types of cestodes obtained by a light microscope.

Objective To introduce the Korean Database of Cerebral Palsy (KDCP) and to provide the first report on characteristics of subjects with cerebral palsy (CP).Methods The KDCP is a nationwide database of subjects with CP, which includes a total of 773 subjects. Characteristics such as demography, birth history, onset and type of CP, brain magnetic resonance imaging (MRI) findings, functional ability and accompanying impairments, were extracted and analyzed.Results Preterm delivery and low birth weight were found in 59.51% and 60.28% of subjects, respectively. Postnatally acquired CP was 15.3%. The distribution of CP was 87.32%, 5.17%, and 1.81% for spastic, dyskinetic, and ataxic types, respectively. Functional ability was the worst in dyskinetic CP, as compared to other types of CP. Speech-language disorder (43.9%), ophthalmologic impairment (32.9%), and intellectual disability (30.3%) were the three most common accompanying impairments. The number of accompanying impairments was elevated in subjects with preterm birth and low birth weight. Brain MRI showed normal findings, malformations, and non-malformations in 10.62%, 9.56%, and 77.35% of subjects, respectively. Subjects with normal MRI findings had better functional ability than subjects with other MRI findings. MRI findings of a non-malformation origin, such as periventricular leukomalacia, were more common in subjects with preterm birth and low birth weight.Conclusion The KDCP and its first report are introduced in this report, wherein the KDCP established agreement on terminologies of CP. This study added information on the characteristics of subjects with CP in South Korea, which can now be compared to those of other countries and ethnicities.

Purpose: Endovascular aneurysm repair (EVAR) for the treatment of abdominal aortic aneurysm (AAA)has shown excellent early outcomes. However, long-term durability continues to be questioned because of endoleaks. The optimal management of type II endoleaks remains controversial because little is known about their long-term natural history. The purpose of this study was to evaluate the natural history of type II endoleaks and to study factors associated with persistent type II endoleaks. Methods: On a retrospective basis, we analyzed 98 patients who underwent EVAR for incidence and outcome of type II endoleaks. Patients with type II endoleaks were evaluated using computed tomography angiography or Duplex scans at one, 6 and 12 months after their EVAR, and annually thereafter to evaluate both the persistence of the endoleak and the size of the aneurysm sac. Results: Type II endoleaks were detected during the follow-up periods in 38 patients (39.8%), who underwent EVAR (mean follow-up: 23.7 months). Spontaneous sealing of type II endoleaks by 6 months after EVAR occurred in 15 patients (39.4%), meaning that there were 23 patients (60.6%) whose leaks were ongoing for more than 6 months. Four patients were treated using embolization because of an enlarging aneurysm sac. Conclusion: Most type II endoleaks are transient and do not require intervention. However, particularly persistent endoleaks could lead to aneurysm enlargement and to delayed aortic rupture. We did not find a significant difference in any number of preoperative patient factors between patients with transient, persistent,or no type II endoleaks. Further studies based on independent data sets are needed to validate these results.
