기종성 신우신염 1례

이재욱,구정태,서정일,양창헌,이정호,이동철,이영현,이활,이경섭 동국대학교 경주대학 1997 東國論集 Vol.16 No.1

기종성 신우신염은 주로 당뇨병환자나 폐쇄성 요로질환을 가진 환자에 발생하며 특징적으로 신실질 및 그 주위조직에 가스를 형성하면서 심한 조직괴사를 일으키는 매우 드문 급성 화농성 신감염으로 사망률이 높은 질환이다. 이 질환은 1989년 Kelly와 MacCallum에 의해 처음 보고된 이래 외국문헌에 약 90례 정도가 보고되어 있으며 국내에는 28례가 보고되어 있다. 수액 및 전해질 보충, 인슐린 투여를 통한 적절한 혈당조절 및 항생제 투여등의 내과적 치료와 절개배농 및 신적출술등의 수술적 치료 방법이 있다. 내과적 치료로 가스의 감소가 없는 경우에는 즉각적인 수술적 치료를 시행하여야하므로 이 가스변화에 대한 추적관찰이 중요하다 하겠다. 본 저자들은 당뇨병환자에서 발생한 기종성 신우신염 1례를 내과적 요법을 치험하였기에 문헌고찰과 함께 보고하고자 한다. Emphysematous pyelonephritis is rare, life-threatening infection of the renal parenchyma and perirenal tisseue. This disease is characterized by the production of intrarenal and perirenal gas and is frequently encountered in patients with diabetes mellitus or urinary obstruction. We experienced a case of emphysematouse pyelonephritis in a 62 years old women with poorly controlled diabetes mellitus who had been managed with medical theraphy. So we report this case with a review of the referenced literatures.

Functional Constraints Focused on Recoverability in Phonology

Lee, Bo Rim,Lee, Ki Jeong 대한언어학회 2000 언어학 Vol.8 No.3

Lee, Borim and Ki-jeong Lee. 2000. Journal of the Linguistic Association of Korea, 8(3), 47-63. In this paper we deal with some functional considerations behind phonological processes which appear to destroy the underlying contrasts. A series of truncation phenomena, in their nature, result in loss of underlying information, which in turn damages intelligibility in communication. From a functional point of view, there may exist certain processes which seem to compensate for the destruction caused by extensive truncation. We discuss a neutralization process, an influence of deleted segments over the remaining segments, a homonymy-avoiding process, and a case of restructuring in a suffix of a secret language of Lardil. We conclude, then, that all these phenomena deserve new interpretations in the context of recoverability of underlying contrasts, which is based on functional constraints in languages.

( Myong Cheol Lim ),( Jeong Seon Lee ),( Jung Nam Joo ),( Sang Soo Seo ),( Sok Bom Kang ),( Sang Yoon Park ) 대한산부인과학회 2012 대한산부인과학회 학술대회 Vol.99 No.-

The objective of this study was to investigate clinical manifestations of lower extremity edema (LEE) in endometrial cancer Medical records for LEE and/or responses to the Gynecologic Cancer Lymphedema Questionnaire (GCLQ) were evaluated in 177 patients with endometrial cancer Patients had a median age of 53 years. Sixty-seven patients (37.9%) had past (9 patients, 13.4%) and/or current patient-reported LEE (58 patients, 86.6%). Symptoms reported on the GCLQ in over 20% of respondents were swelling, numbness, aching , and heaviness. GCLQ total symptoms score was significantly higher in patients with current LEE. Most of the LEE (43/67, 64.2%) developed within 12 months after surgery and LEE lasted more than 6 months in most patients (56/59, 94.9%) Prospective clinical trials are needed to know the clinical significance, impact on quality of life, and preventive strategy of LEE in patients with endometrial cancer

혈액 투석 환자에서 중심정맥 협착에 대한 스텐트 삽입술 : Wallstent Placement

Stenosis of central vein is a common complication arising after percutaneous subclavian vein catheter insertion performed for temporary vascular access in chronic renal failure patients undergoing hemodialysis. There are several treatment methods for the condition like percutaneous angioplasty(PTA), stent insertion, and surgery, but recent trend is toward PTA and stents. Among the patients diagnosed with chronic renal failure from March 1993 to May 2002 and undergoing hemodialysis through AV fistula, the 14 Patients in whom central vein stenosis arose were selected for the study. A total of 28 percutaneous interventions(5 PTA and 23 stent placement) were performed, and restenosis rate and the time taken till the restenosis in de novo lesions and instant lesions were compared. All 28 cases were operated successfully. The 14 cases that received both anigioplasty and stent placement initially. (de novo lesion : 14 cases), Among the 10 cases with de novo lesion that followed up more than 1 year, 3 cases are currently undergoing hemodialysis without restenosis, and the remaining 7 cases have recurred stenosis with the mean time to restenosis of 10.9 months. In the 7 cases in whom stenosis recurred, 11 interventions were done(instent lesion: 11 cases). 4 of these were using only ballon angioplasty with 100% restenosis rate and the mean time of 3 months until restenosis. The remaining 7 cases were using both balloon angioplasty and stent placement, also with 100% restenosis rate but with the mean time of 12 months until restenosis, which was later than the group receiving only balloon angioplasty. In treating the patients with central vein stenosis, stent placement seems to be more advantageous over PTA in terms of restenosis rate and the mean duration of patency. In the case of instent lesion, inserting the stent for the second time after stenosis recurred lengthened the duration of patency compared to performing balloon angioplasty alone.

이정우,박형서,박용규,노상필,이유선,정승현,김보영,이재환,최시완,정진옥,성인환 충남대학교 의과대학 의학연구소 2003 충남의대잡지 Vol.30 No.1

목적 : 관상동맥의 경련에 의한 이형성 협심증환자에 있어서 운동부하 심전도 검사의 결과는 매우 다양하다. 이에 저자들은 충남대학교병원 순환기내과에서 관상동맥조영술상 이형성 협심증으로 확진된 환자를 대상으로 운동부하 심전도 검사를 시행하여 이에 대한 결과를 연구하였다. 방법 : 1995년 1월부터 2002년 3월까지 흉통을 주소로 충남대학교병원 순환기 내과에 입원하여 관상동맥조영술을 시행하여 관상동맥의 내경이 50% 미만의 협착이 있고, 에르고노빈(ergonovine) 유발검사도 이형성 협심증으로 진단을 받은 233명중 운동부하 심전도 검사를 시행 받은 183명의 환자를 연구 대상으로 하였다. 운동부하 심전도 검사 결과의 판독시 발생할 수 있는 오류를 줄이기 위해서 운동부하 심전도 검사를 시행하기전 심전도상 ST분절의 상승(5예)이나 하강(8예)이 있는 경우 EH한 T파의 역위(19예)가 있는 32명의 환자를 제외한 총 151명의 환자를 대상으로 하였다. 운동부하는 Marquette사의 case 15 답차를 이용하였고, Bruce protocol에 따라 증상이 나타날 때까지 최대로 실시하였으며 각 stage 및 운동후의 혈압을 측정하고 12 유도 심전도를 기록하였다. 결과 : 1) 임상적 특성 - 내원시 임상 상은 안정형 협심증이 39예(25.8%), 불안정형 협심증이 103예(68.2%), 심근경색증이 9예(6.0%)이었다. 운동부하 심전도 검사 결과 양성 군과 음성군간에 있어서 당뇨병, 고혈압, 비만도, 총 혈청콜레스테롤치, 현재의 흡연 여부, 병력상 운동시 흉통의 유무, 내원시 임상적 진단, 협착의 정도, 연축의 수 등을 조사하였는 바 어떠한 인자들도 유의한 차이를 발견할 수 없었다. 2) 운동부하 심전도 검사 - 운동부하 심전도 검사를 시행 받은 151명의 환자중 음성인 경우는 134예(88.8%)이었고, 양성인 경우는 17예(11.2%)이었다. 양성 소견을 보인 환자들중 ST 분절의 상승이 4예(2.6%), ST 분절의 하강이 13예(8.6%)이었다. 3) 관상동맥조영술 - 관상동맥조영술상에서 혈관 경력 위치는 우관상동맥이 70예(46.1%), 좌전하동맥이 44예(28.9%), 좌회선동맥이 17예(11.2%)의 순으로 나타났다. 운동부하 심전도 검사상 ST 분절의 상승이 있었던 예중 Ⅱ, Ⅲ, aVF에서 ST 분절의 상승이 있었던 1예는 관상 동맥조영술상 우관상동맥에서 경련이 발생하였고, V2-V4에서 ST 분절의 상승이 있었던 2예중 관상동맥조영술상에도 좌전하행동맥에서 경련이 나타난 예는 1예이었으며 다른 1예는 좌회선동맥에서 경련이 나타났고, V5-V6에서 ST 분절의 상승이 있었던 1예는 관상동맥조영술상에도 좌회선동맥에서 경련이 나타났다. 운동부하 심전도 검사상 V5 또는 V6에서 ST 분절의 하강이 있엇던 13예중 6예(46.1%)는 관상동맥조영술상 우관상동맥에서 경련이 발생하였고, 3예(23.1%)는 좌전하행동맥에서, 1예(7.7%)는 좌회선동맥에서, 나머지 3예(23.1%)는 2개의 혈관이나 기타 분지에서 경련이 발생하였다. 결론 : 1) 이형성 협심증 환자는 운동부하 심전도 검사에서 11.2%의 양성소견을 보였다. 이중 ST 분절의 상승은 2.6%이었고, ST 분절의 하강은 8.6%이었다. 2) 이형성 환자중 운동부하 심전도 검사를 실시하여 음성을 보이는 경우 다혈관 관상동맥질환이기 보다는 이형성 협심증일 가능성이 더 높다고 예측할 수 있을 것으로 생각된다. 3) 이형성 협심증 환자중 운동부하 심전도 검사를 실시하여 ST 분절의 상승을 보이는 경우 다혈관 관상동맥질환이기 보다는 이형성 협심증일 가능성이 더 높다고 예측할 수 있을 것으로 생각된다. 4) 운동부하 심전도 검사 결과에 대한 당뇨병, 고혈압, 비만도, 총 혈청콜레스테롤치, 현재의 흡연여부, 병력상 운동시 흉통의 유무, 내원시 임상적 진단, 협착의 정도 등 어떠한 인자들도 3그룹(ST 분절의 상승, ST 분절의 하강, 음성)간에 유의한 차이를 발견할 수 없었다. 5) ST 분절의 상승 부위와 관상동맥조영술상 관상동맥의 연축이 일어나는 혈관과의 상관관계는 매우 높았다. No reports in the literature describe the results of exercise testings in a large number of patients with pure variant angina(coronary stenosis <50%) in Korea. In this report, We present the results of treadmil exercise testing in 151 patients with variant angina. 151 patients with angiographically proven coronary artery spasm underwent a treadmil exercise test. The clinical characteristics of variant angina patients classified according to ST-segment response to exercise were analyzed. Of 151 patients underwent a treadmil exercise test, negative result was seen in 134 patients(88.8%) and positive result was in 17 patients(11.2%). Of 17 patients saw positive result, exercise-induced ST segment elevation was present in 4 patients(2.6%) and ST segment depression was seen in 13 patients(8.6%). There was not a significant relationship between the ST segment response to exercise and the clinical variables(diabetes, hypertension, obesity, total cholesterol, current smoking, effort angina, clinical diagnosis, and degree of stenosis) assessed. Of 4 patients with ST segment elevation in treadmil exercise test, 1 patient with ST segment elevation in Ⅰ,Ⅲ,aVF had spasm in right coronary artery(100%) on coronary angiography, of 2 patients in V2-V4 had spasm in left anterior descending coronary artery in 1 patient(50%) and 1 patient in V5-V6 had spasm in left circumflex artery(100%). Positive treadmil exercise test was present in 11.2% of variant angina patient. If we have negative treadmil exercise result in patients with clinical manifestation of unstable angina at admission, we may have a suspicion of variant angina rather than multi-vessel disease. If we have exercise-induced ST segment elevation in patients with clinical manifestation of unstable angina at admission, we have a suspicion of variant angina rather than multi-vessel disease. Our result suggests that the correlation between the site of the ST segment elevation and the artery involved is quite good.

내측 측두엽 간질에서 간질발작 중 언어증상

이장준,이승환,이형,김지언,임정근,손은익,이상도,박영춘 계명대학교 의과학연구소 2000 계명의대학술지 Vol.19 No.1

Background and Objectives : Several speech manifestation are observed in temporal lobe epilepsy(TLE). We studied the frequency of ictal speech manifestations and their localizing and lateralizing value in TLE. Methods : We reviewed 379 seizures recorded on videotape in 135 patients who underwent temporal lobectomy for intractable TLE. We divided patients into group A(n=75) who became seizures free after surgery, and group B(n=60) who were only slightly benefited or unchanged after surgery. Speech manifestations were classified as normal speech, vocalization, or abnormal speech. Abnormal speech was subdivided into speech arrest, dysarthria, dysphasia, or nonidentifiable speech. Results : Speech manifestations occurred in 70(18.5%) seizures of 28 patients. Forty eight seizures of 20 patients were observed in group A, and 22 seizures of 8 patients were observed in group B. In group A, 25 seizures of 11 patients were originating from dominant hemisphere, 23 seizures of 9 patients from nondominant hemisphere. In group B, 13 seizures of 5 patients were originating from dominant hemisphere, and 9 seizures in Lt. side and 6 seizures in Rt. side, respectively) of group A(P>0.05), and eleven seizures of 4 patients(8 seizures from Lt. side and 3 seizure from Rt. side) in group B(P>0.05). Normal speech was observed only seizures from Rt. side in both groups(3 seizures in 1 patient, each group). Dysphasia occurred only in seizures originating from Lt. side. Nonidentifiable speech occurred in 22 seizures of 9 patients(11 seizures from each side) in group A(P<0.01), and 3 seizures of 1 patient occurred only from Lt. side in group B. Conclusion : Ictal speech manifestations were not uncommon(18.5%). All kinds of ictal speech manifestations except normal speech have no reliable lateralizing and localizing value in TLE. Normal speech could be a good indicator of seizure originating from nondominant hemisphere.

이재숙,조윤정,손정원,이갑노 고려대학교 의과대학 1994 고려대 의대 잡지 Vol.31 No.3

To evaluate the relationship between c-myc amplification and leukemic transformation. The Southern hybridization was performed in 23 clinical leukemic samples(4 cases of ALL, 17 cases of ANLL, 1 case of CML, 1 case of CMMoL), 6 ATCC leukemic cell lines(ATCC CCL 213 Daudi;Burkitt lymphoma, ATCC CCL 243 K-562;chronic myelogenous leukemia, ATCC CRL 2582 Molt-4;T-cell acute lymphoblastic leukemia, ATCC CCL 240 HL-60; promyelocytic leukemia, ATCC CCL 246 KG-1;acute myeloblastic leukemia, ATCC CCL 246.1 KG-1a;acute myeloblastic leukemia), and 6 cases of nonleukemic bone marrow aspirates. The results were summarized as follows. 1. In leukemic cell lines, HL-60 showed marked c-myc amplification(6x) compared to negative control and KG1 showed mild amplification(2x). However, there was no c-myc amplification in K-562, KGla, and molt-4. 2. In leukemic samples, mild c-myc amplification(2x) was observed in 3 cases of 17 AML, but no amplification was observed in 4 ALLs, 1 CML, and 1 CMMoL. 3. In nonleukemic samples, one case of reactive marrow hyperplasia showed mild c-myc amplification (2x). From the above findings, it was concluded that the c-myc amplification was more common in acute nonlymphocytic leukemia than other types of leukemias, c-myc amplification appeared not only enough to transform hematopoietic cells but expression of other complicated oncogenes together with it cotributed the development of leukemia.
