경기도(京畿道) 여주군(驪州郡)에 있어서의 간흡충감염실태조사(肝吸?感染實態調査)
주경환,최득린,임한종,Joo, Kyoung-Hwan,Choi, Deuk-Lin,Rin, Han-Jong 한국농촌의학지역보건학회 1982 농촌의학·지역보건 Vol.7 No.1
Clonorchiasis sinensis is one of the most important endemic diseases in Korea, and this disease has been known to be one of public health concern in many areas of Korea. This survey was undertaken to evaluate the status of clonorchiasis in Yeoju Gun, Gyeong-gi Do from July to September 1980. A total of 1,194 male students were examined by intradermal test with Clonorchis antigen. In order to detect Clonorchis egg, the stool examinations were undertaken to 1,158 students, and the intensity of the Clonorchis infection was estimated by the Stoll's egg count. The prevalence rate was reanalyzed by the regional groups for an investigation of regional characteristics of infection. The following results were obtained in this survey. 1) Among 1,194 students in Yeoju Eup, positive rate of intradermal test with C. sinensis antigen was 17.2 percent. (middle school14.6% and high school 20.1%). 2) In the examination of 1,158 stool specimens, Clonorchis eggs were found in 97 (8.4%) cases. 3) Mean E.P.G. of Clonorchis infected case was $1,330{\pm}2,620$. 4) The degree of the intensity of Clonorchis infection by E.P.G. count was distributed as 73.6% in light infection (100-999), 22.6%, in moderate infection (1,000-9,999), and 3.8% in heavy infection (10,000-29,999). 5) High prevalence rate of Clonorchis sinensis was found in the Sang-Ri(9,3%) and Ha-Ri(8.4%) in Yeoju Eup. Neighbouring Bugnae Myun (11.5%), Gangcheon Myun(12.1%) and Neungseo Myun (11.1%) adjacent to the river had a similary high prevalence of C. sinensis.

소아의 방광 요관 역류 진단시 X-ray 배뇨성 방광 요도 조영술(X-ray VCUG)과 방사성 동위원소 배뇨성 방광 요도 조영술(RI VCUG)의 비교
홍현숙,최득린,김은미,김성준,Hong Hyun-Soook,Choi Deuk-Lin,Kim Eun-Mi,Kim Sung-Jun 대한소아신장학회 1999 Childhood kidney diseases Vol.3 No.2
목적 : 방광요관역류는 방광에서 요관과 신장으로 소변이 역류하는 현상으로 요로감염증의 약 1/3에서 발견되며 정도는 1도에서 5도까지 나눌수 있다. 소아의 방광요관역류의 진단에 있어 사용되는 RI VCUG(Radioisotope voiding cystourethrography(이하 VCUG)) 와 X-ray VCUG의 결과를 비교하여 방광요관역류의 진단에 어느 방법이 더 유용한지 평가하고자 본 연구를 시행하였다. 방법 : 1991년 1월부터 1998년 7월까지 7년 6개월동안 순천향병원 소아과 외래를 방문한 환아중 잦은 요로감염증이나 초음파 검사상 이상소견을 보인 9개월에서 17세까지 평균 5년 6개월의 남아 19명, 여아 21명을 대상으로 대상환아들에게 X-ray VCUG나 RI VCUG 또는 두가지 방법을 동시에 시행하였으며 요검사와 소변 배양검사를 1개월마다, 신장 초음파 검사를 3개월마다, RI VCUG를 6개월마다 추적검사를 시행하여 방광요관역류의 소실여부를 관찰하며 예후를 평가하였다. 결과 : 대상환아중 24명이 RI VCUG를 시행하여 17명이 방광요관역류소견을 보여 70.1%의 양성률을 보였고 22명이 X-ray VCUG를 시행하여 9명이 방광요관역류소견을 보여 40.1%의 양성률을 보였으며 19명이 두가지 검사를 모두 시행하여 15명이 RI VCUG상 양성소견을 보였고 이중 7명이 X-ray VCUG상 양성소견을 보였고 RI VCUG상 음성소견을 보인 4명은 X-ray VCUG 상에서도 음성소견을 보였다. 방광요관역류환아의 예후는 중복신장을 동반한 1례에서는 수술로 교정되었으며 다낭포신을 동반한 1례에서는 역류가 지속되었고 그외 단순한 역류에서는 자연소실과 반혼의 형성이 각각 8명이었으며 역류가 지속된 경우가 5명, 수술로 교정된 경우는 2명, 신기능이 감소된 경우가1명, 추적관찰이 되지않은 경우가 1명이었다. DMSA(2,3-dimercaptosuccinic acid 이하 DMSA) sacn상 방광요관역류환아 9명중 8명이 반흔을 형성하였고 역류가 없던 8명에서는 반흔을 형성하지 않았다. 요배양검사상 방광요관역류환아가 19명중 17명으로 역류가 없던 환아 21명중 15명이 양성소견을 보인것보다 양성률이 높았으며 원인균으로는 대장균이 가장많았고 방광요관역류환아에서 요로감염이 없던 기간은 14개월로 방광요관역류가 없는 환아에서의 26개월보다 짧았다. 결론 : 소아의 방광요관 역류의 진단에 있어 RI VCUG가 X-ray VCUG보다 양성률이 높음을 확인할수 있었다. 그러므로 초기진단시 방광요관 역류가 의심되나 X-ray VCUG로 발견되지 않은 경우에는 RI VCUG를 꼭 시행하는 것이 방광요관역류의 정확한 진단을 하는데 도움이 된다. Purpose : VUR is state where urine regurge from bladder to ureter and kidney. It is shown in about 1/3 of urinary tract infection patients and it is classified as grade I to V. We compared results from RI VCUG(Radiisotope voiding cystourethrography) and X-ray VCUG which used in diagnosing VUR in children, to evaluate which is better in diagnosing VUR in children. Methods : 41 Patients(19 males, 21 females), who visited Pediatric department, Soonchunhyang university Hospital from peroid of 1991. January to 1998. July for recurrent urinary tract infection or abnormalities in ultrasonogams, were enrolled in the study. The age ranged from 9 months to 17 years and mean age was 5 1/2 years. Both RI VCUG and X-ray VCUG were done and follow-up test of urine culture, renal ultrasonogram and RI VCUG were done every month, every 3 month and every 6 month, respectively to observe the disappearance of VUR and evaluated the prognosis. Results : 24 patients had taken RI VCUG and 17(70.1%) patients showed positive result. 22 patients had taken X-ray VCUG and 9(40.1%) patients showed findings of VUR. 17 patients had taken both tests and 14 patients showed positive result in RI VCUG and 6 of these patients also showed reflux in X-ray VCUG. 3 patients who showed negative in RI VCUG, showed negative also in X-ray VCUG. For prognosis, resolution and scar formation was shown in 8 patients each. Persistent VUR was shown in 6 patients and 2 of these patients VUR was corrected by operation, 1 patient showed decreased renal function, and 1 patient was not follwed up. 8 of 9 patients who showed findings of VUR on DMSA scan formed a scar and 8 patients who showed no findings of VUR didn't form a scar. Urine culture was positive in 17 of 19 patients with VUR. Positive rate in urine culture was higher than that of patients with no VUR who showed positivity in 15 of 21 patients for urine culture. E. coli was most common organism and the period free of UTI was 14 months in VUR patients and it was shorter compared to patients without VUR which was 26 months. Conclusion : In diagnosing VUR in children, the positive rate was higher in RI VCUG than X-ray VCUG. Therefore, in early diagnosis when VUR is suspicious but not shown in X-ray VCUG, RI VCUG should be done and it will help to make accurate diagnosis.

공허안(empty sella): MRI상 발생 빈도와 그 의의
안영,홍현숙,박재성,김대호,이혜경,정무찬,최득린,김기정,Ahn, Young,Hong, Hyun-Sook,Park, Jae-Sung,Kim, Dae-Ho,Lee, Hae-Kyung,Chung, Moo-Chan,Choi, Deuk-Lin,Kim, Ki-Jung 대한영상의학회 1991 대한영상의학회지 Vol.27 No.6
Anatomic differentiation of the sella turcica has been greatly improved by introducion of MR over the previously used pneumoencephalography and CT. Because we frequenthy encounter the empty sella in MR imaging, we retrowpectively reviewed and classified 239 incidental empty sellae of 1004 patients who had brain MR. All cases which had initial suspicion of pituitary or hypothalamic lesions were excluded. Although headache is the most common presenting symptom, the associated disease and not specific. The incidence of the empty sella(23.8%) is similar to that reported at autopsy cases increased by the aging process. Therefore, we suggest that empty sella can be a normal variant or a degenerative change.

조성우(Sung Woo Cho),김종수(Jong Soo Kim),김영선(Young Sun Kim),정연태(Yeon Tae Chung),김용훈(Yong Hoon Kim),박춘식(Choon Sik Park),정무찬(Moo Chan Jeong),최득린(Deuk Lin Choi),김기정(Gi Jeong Kim) 대한내과학회 1989 대한내과학회지 Vol.37 No.2
N/A We evaluated the diagnostic value of the 99m-Technetium DTPA radioaerosol ventilation scan in 22 patients who were suspected to have pulmonary embolism because of perfusion defects. 1) Nine patients showing matched defects on the ventilation-perfusion scan were excluded from pulmonary embolism. 2) Among the 13 patients with pulmonary embolism, 9 patients showed normal ventilation scans and 4 patients showed smaller defects on the ventilation scan than on the perfusion scan due to 2 cases of pulmonary infarction, 1 case of pleural effusion and 1 case of atelectasis. 3) Sizes of defects were multiple segmental in 2 cases, multiple lobar in S cases and more than one lung in 3 cases. We conclude that 99mTc-DTPA radioaerosol is useful in the ventilation lung scan for the diagnosis of pulmonary embolism.

소아 급성 신우신염환아의 색도플러 초음파 검사의 유용성
김은미,권귀향,이혜경,홍현숙,최득린 순천향의학연구소 1998 Journal of Soonchunhyang Medical Science Vol.4 No.1
Purpose: Urinary tract infections are common in childhood and are most frequent in those under 1 year of age. In these children, however, differentiation of the pyelonephritis from cystitis is clinically difficult. We investigated the utility of color doppler image ultrasound in the diagnosis of acute pyelonephritis(APN) in children. Results were compared with renal cortical scintigraphy using 99mTC-DMSA. Materials and Methods : 99mTc-DMSA SPECT and color doppler ultrasound were performed within 1 week intervals in 14 patients with clinically suspected APN. (aged 4months to 15years: mean 6.1 year, 7 girls and 7boys). Urine culture was considered positive if greater than 100.000 colonied of a single organism were isolated. CDI was performed with 3.5NHz convex linear probe Ultramark 9(ATL., Bothell, Washington, USA) following a standard gray scale sonogram of the kidneys. Renal cortical scintigraphy was performed with 99mTc DMSA SPeCT(PRISM 2000, Picker, USA), Axial, coronal, both sagittal pinhole images were obtained 1.5-2 hour after 1mCi isotope was injected. Renal scan was considered to be abnormal and indicative of APN when there was a focal, wedged shaped defect in radionuclide accumulation extending from the periphery of the kidney to centrally or if there was diffuse abnormality in renal tubular function. Renal scarring was defined when defects were shallow lesions along the periphery of the kidney with evidence of volume loss, or if they could be shown from prior examination to pre-date of the acute episode. The color doppler image were interpreted to be consistent with APN if there was decrease flows in the renal cortex. Results: Of the 28 kidneys were examined, renal scan showed 5 cases of abnomal findings, 3 cases were APN, 2 cases were chronic scarring. Two fo the three cases of APN showed decreased blood flow on CDI and positive culture, for a sensitivy 67%. Two cases of renal scarring due to grade V bilateral vesicoureteral reflux show decreased blood flow at right upper pole kidney on CDI, however DMSA scan had diffculties finding the new lesion due to underlying irregularity of scarred kidney. Color doppler US correctly identified 4 of 5 renal poles with APN and 21 of 23with no APN including 2 patients with false positive. The DMSA scan was used as the standard of comparison the study; the CDI has a sensitivity 67%, specificity 84%, positive predictive value 33%, negative predictive value 95%. 84% The lesion showed decreased blood flow and on one follow up case increased blood flow. The presence of prior renal scarring made interpretation of asymmetric vascularity difficult on DMSA, the use of CDI may increase the diabnostic sensitivity of sonography in pediatric pyelonephritis.

안정성과 불안정성 박리성 골연골염의 감별에서 자기공명 양상소견 : 자기공명영상 기준의 재평가
최득린 순천향의학연구소 2008 Journal of Soonchunhyang Medical Science Vol.14 No.1
Objective: To assess the radiographic and MR features of osteochondritis dissecans(OCD) in the knee, ankle and elbow and reappraise the criteria for differentiating stable and unstable OCD by using MRI. Materials and Method: The author retrospectively reviewed 16 cases of OCD who had correlative arthroscopy or arthrotomy. There were 15 patients with an average age of 18 years(12-41 years). The author analysed age, location, shape, signal intensity, articular cartilage, subchondral bone, abnormal fluid collection and displacement of OCD if any. Results: 12 cases in femoral condyle(7 in MFC and 5 in LFC), 2 cases in medial talar dome and 2 cases in capitulum. Stable OCD were present in 4(25%) and ubstable OCD in 12(75%)of 16 cases. Radiography showed poor correlation with arthrography and 7 cases were understaged. MRI proved accurate in discriminating stable(4 of 4 cases) versus unstab1e(12 of 12 cases) OCD. Conclusion: The author conclude that high signal intensity line between OCD and underlying bone, defect of articular cartilage and subchondral bone cyst, displacement of fragment(if any) on T2WI of MRI are strongly suggestive findings of unstable OCD. MRI is very sensitive method of detecting instability of OCD and can predict arthroscopic findings accurately.
