          무지외반증에서 근위 갈매기형 절골술 후 고정 방법에 따른 차이: K-강선, 유관나사, 금속판

          김택선,김학준,박영환,임형태,Kim, Taik-Seon,Kim, Hak-Jun,Park, Young-Hwan,Lim, Hyung-Tae 대한족부족관절학회 2011 대한족부족관절학회지 Vol.15 No.2

          Purpose: The authors evaluated the differences between K-wires and Cannulated screw, plate for fixing the proximal metatarsal chevron osteotomy of moderate and severe hallux valgus. Materials and Methods: There were 62 patients (79 feetz) who were moderate and severe degree hallux valgus according to the classification of Mann. They all got the proximal chevron osteotomy when correcting the deformity. We divided the patients into 4 groups, Two K-wire fixed group as A, one cannulated screw fixed group as B. Two cannulated screw fixed group as C, Plate fixed group as D, Group A were patients (26 feet) and Group B were patients z(9 feet), Group C were patients (31 feet) and Group D were patients (13 feet). Preoperative, postoperative and follow-up hallux valgus angle (HVA) and intermetatarsal angle (IMA) were measured for each patient. ANOVA test and Student t-test were done for statistical analysis. Results: Mean follow up period was 43.8 months (range: 12~82 months). Preoperative mean IMA was $16.4{\pm}3.5$, $17.7{\pm}11.3$, $17.3{\pm}5.9$ and $16.6{\pm}2.3$ degrees in respectively group A, B, C, D. Immediate postoperative mean IMA was $5.6{\pm}3.4$, $7.3{\pm}4.4$, $7.6{\pm}4.4$ and $6.7{\pm}2.8$ degrees in respectively group A, B, C, D. The final mean IMA was $8.9{\pm}4.5$, $15.2{\pm}7.5$, $10.3{\pm}4.4$ and D $7.7{\pm}3.5$ degrees in respectively group A, B, C, D. There were significant statistical increase in final mean IMA of group B and C (p<0.05). Conclusion: The IMA was significantly increased in the group which used one or two cannulated screw for fixation on follow up, therefore more caution should be needed when using one or two cannulated screw fixation technique after proximal chevron osteotomy.

        • 하퇴부에 발생한 고립성 퇴행성 신경초종 -증례 보고-

          김택선,김학준,김완태,김윤정,윤재은,Kim, Taek-Seon,Kim, Hak-Jun,Kim, Wan-Tae,Kim, Yoon-Jung,Yoon, Jae-Eun 대한근골격종양학회 2006 대한골관절종양학회지 Vol.12 No.1

          신경초종이 오래되어서 퇴행성 변화를 일으키면 이를 퇴행성 신경초종이라고 명칭하며, 드물게 보고되고 있다. 혈관주변의 초자화, 출혈, 석회화, 낭성 괴사, Antoni A 구역의 축소, 핵의 변형 등의 퇴행성 변화가 나타날 수 있으며, 이러한 퇴행성 변화로 인해 육종 등으로 잘못 진단되기 쉽다. 본원에서는 75세 남자 환자의 하퇴부에서 광범위한 출혈과 혈종, 낭성 변화, 석회화, Antoni A 구역의 축소 등의 퇴행성 변화가 진행된 퇴행성 신경초종을 경험하였기에 문헌적 고찰과 함께 이를 보고하는 바이다. When the old schwannoma has the degenerative changes, it is named as the ancient schwannoma which was rarely reported. The degenerative changes are perivascular hyalinization, calcification, cystic necrosis, marked decrease of Antoni type A area, and degenerative nuclei and the ancient schwannoma may be misinterpreted as sarcomatous pleomorphisms. We experienced the ancient schwannoma which has massive hemorrhage and hematoma, cystic change, calcification, and marked decrease of Antoni A area in leg on 75 year old male patient, and report it.

          고령에서 발생한 제1 요추의 호산구 육아종 : 1례 보고 1 Case Report

          김택선,이석하,이동기,성낙훈 대한척추외과학회 1999 대한척추외과학회지 Vol.6 No.3

          호산구 육아종은 청소년기에 특징적으로 발생사는 양성 종양이다. Histiocytosis의 아분류로 취급 되다가 조직학적 소견이 동일하여 현재는 Langerhans 세포 조직구증으로 불려진다. 골겨계 어디나 침범하지만 두개골에 가장 호발하며, 척추 병소는 10~15%정도이다. Birbeck granules를 세포질내 함유한 Langerhans 세포가 특징적이고 조직구 및 호산구의 증식을 보인다. 저자들은 고령에서 발생한 요추의 호산구 육아종 1예을 경험하였기에 문헌고찰과 함께 보고하는 바이다. Eosinophillic granuloma of bone is a self-limited ondition, characteristically a disease of children and young adults. It is the nost benign variant of histiocytosis X. It is most common in skull, but any bone may be affected. Vertebral involvement occurs in about 10 to 15%. This benign bone destructive lesion is characterized by the presence of Langerhans cells contain Birbeck granules, infilitration of histiocytes and eosinophilic leukocytes unknown origin. We report a eosinophilic ggranuloma in lumbar spine of old patient.

        • Bis-Diazotized Benzidine에 의한 연속 및 동시흡착법에 의하여 Tuberculin PPD로 감작된 적혈구를 이용한 혈구응집반응의 민감성

          김택선,정상인,최철순,양용태 중앙대학교 의과대학 의과학연구소 1984 中央醫大誌 Vol.9 No.3

          Passive haemagglutination test(PHA) using sheep red blood cells(SRBC) sensitized with soluble antigens by means of coupling agents, i.e., tannic acid, bis-diazotized benzidine(BDB), chromic chloride, glutaraldehyde, and so on, provide an extremely sensitive technique to detect a minute quantity of serum antibody as low as 0.01㎍. It also has advantage over agglutination and precipitation tests in that if it is transferred either to hemolysis test(PHL) or to inhibition test(PHI), soluble antigen-antibody complexes and incomplete or hapten antigen-nonprecipitating antibody complexes that are not detectable by other tests can be demonstrated. This study was undertaken to determine the optimum amount of BDB and tuberculin PPD antigen for consecutive and simultaneous coupling of SRBC in conjunction with the sensitivity of the PHA test. In addition, the sensitivities of PHA and PHL test were compared and the PHA units of antibody and diluents for tuberculin PPD antigen for PHI test were discussed. The results are summarized as follows: 1. The optimum amount of BDB for consecutive and simultaneous coupling of 0.2ml of 2.5% SRBC were 20㎍ and 13㎍, respectively, and the optimum amount of tuberculin PPD antigen were about 125㎍ and 250㎍ respectively. The optimum ratios between BDB and tuberculin PPD antigen for consecutive and simultaneous coupling were 1:6.3 and 1:19.2, respectively. 2. In the consecutive coupling, the PHA titre was linear to both BDB and tuberculin PPD concentrations, whereas in simultaneous coupling it was affected by the level of tuberculin PPD but not by that of BDB from 5㎍ to 13㎍. 3. Using SRBC sensitized consecutively with tuberculin PPD or sensitins prepared from four species of mycobacteria the homologous PHL tests were sensitive than the PHA tests by 1:2 to 1:4 dilutions, and the end-point of PHL test was more clear-cut than that of PHA test.

        • Yersinia enterocolitica O:1,2,3 군과 O:3 군의 균체응집항원과 침강항원의 특이성

          김택선,최철순,양용태 중앙대학교 의과대학 의과학연구소 1989 中央醫大誌 Vol.14 No.1

          By means of bacterial agglutination, agar gel-diffusion, rocket and two-dimentional immunoelectrophoresis, antigenic relationships of bacterial agglutinogens and precipitinogens between three strains of serogroup 0: 1,2,3 and two strains of serogroup 0:3 of Yersinia enterocolitica were studied. The results were summarized as follows: 1. Crossed bacterial agglutination reactions between strains of 0:1,2,3 and 0:3 to homologous and heterologous rabbit immune sera showed so close relations that strains of two serogroups were not differentiated one another by agglutination test using rabbit anti -0:1, -0:2 and -0:3 sera. 2. Bacterial antigens of 0:1, 2 ,3 cross-reacted with both anti-0:1 serum absorbed with 0:2 and 0:3 groups and anti -0:2 serum absorbed with 0:1 and 0:3 groups, whereas the bacterial antigens of 0:3 group reacted with only absorbed anti-0:1 serum. 3. Out of three bacterial soluble antigens extracted with 0.3% phenol-phosphate buffered saline (PBS), 0.1% Triton X-100-phosphate buffer and 10% trichloroacetic acid solution, the precipitinogen of PBS extract was most highly reactive and stable up to 121˚C for 30 min. The precipitinogen, however, heated at 60˚C for 30 min was more reactive. The heat-stable surface antigen of 0:1,2,3 group was antigenically identical with the antigen of 0:3 group. 4. Fused rocket immunoelectrophoresis revealed that the antigens of 0:1,2,3 and 0:3 groups had one to two common antigens which had a rapider mobility than group specific antigens. 5. By crossed immunoelectrophoresis, the precipitinogens of 0:1,2,3 group had four to five antigens having the relative electrophoretic mobility of 0, 0.15 - 0.18, 0.41, 0.47 -0.5 and 0.58, whereas the precipitinogens of 0:3 group had three antigens having the relative electrophoretic mobility of 0, 0.15 - 0.18 and 0.47 - 0.5. These results indicated that although the strains of 0:1,2,3, group would differ in their subagglutinogens from those of 0:3 group they belonged to 0:3 group by their common 0 group-specific precipitinogens.

          무지 외반증의 근위 갈매기형 절골술 후 고정 방법에 따른 결과 차이

          김택선,강규복,강종우,김학준,Kim, Taik-Seon,Kang, Kyu-Bok,Kang, Jong-Woo,Kim, Hak-Jun 대한족부족관절학회 2008 대한족부족관절학회지 Vol.12 No.1

          Purpose: The authors evaluated the differences between K-wires and Bold screw for fixing the proximal metatarsal chevron osteotomy of moderate and severe hallux valgus. Materials and Methods: There were 59 patients (81 feet) who were moderate and severe degree hallux valgus according to the classification of Mann. They all got the proximal chevron osteotomy when correcting the deformity. All patients were followed up at least 6 months. We divided the patients into 2 groups, K-wires fixed group as A, Bold screw fixed group as B. Group A were 42 patients (63 feet) and Group B were 18 patients (19 feet). Among the Group B, 2 feet who were failed to fix the oetotomy site with Bold screw, were fixed with K-wires during operation. We measured the AOFAS score preoperatively, postoperatively and at final follow-up, VAS score at 2 weeks after the operation. Also preoperative, postoperative and follow-up hallux valgus angle (HVA) and intermetatarsal angle (IMA) were measured for each patients. Results: Mean follow up period was 1.34 year (range: 6 months-6.16 years). Mean VAS score of group A was $3.21{\pm}1.7$ and group B $1.76{\pm}1.0$. Preoperative mean AOFAS score of group A was $45.61{\pm}8.3$, group B $44.41{\pm}8.9$, the final mean score of group A was $88.87{\pm}8.3$ and group B $92.47{\pm}4.4$. Preoperative mean HVA was $30.82{\pm}6.6$ degrees in group A and $32.88{\pm}14.5$ degrees in group B, the final mean angle of group A was $14.89{\pm}8.3$ degrees and group B $17{\pm}4.4$ degrees. The preoperative mean IMA of group A was $13.69{\pm}3.6 $degrees and group B $12.35{\pm}5.2$, the final mean angle of group A was $9.26{\pm}3.6$ degrees and group B $12.35{\pm}5.8$ degrees. Conclusion: There were no statistical differences in radiologic and clinical results (p>0.05) but, group B exceeded group A in VAS score (p=0.0007) and had no statistical significance in terms of reduction angle loss (p=0.06). Early returning to normal life activity may be possible for patients using Bold screws.

          당뇨병성 족부 질환에 의한 하지 절단 후 임상적 분석과 결과

          김택선,강종우,이상준,허영재,김학준,Kim, Taik-Seon,Kang, Jong-Woo,Lee, Sang-Jun,Huh, Young-Jae,Kim, Hak-Jun 대한족부족관절학회 2009 대한족부족관절학회지 Vol.13 No.1

          Purpose: The authors evaluated the clinical results and prognosis after amputating the lower extremity due to diabetic foot. Materials and Methods: From 1991 to 2003, the patients who had suffered amputation of his lower extremity due to diabetic foot ulcer were evaluated retrospectively. 79 patients were male and 6 patients were female. The author evaluated the patient who had the ipsilateral additional surgery, contralateral amputation, level of blood sugar, combined disease and mortality rate within 5 years from medical record. Statistical analysis was done by Chi-square test and Kaplan-Meier survival test. Results: Mean age of patients who had first experienced amputation was 63.4 years old. The mean duration of diabetes until amputation was $14.5{\pm}7.5$ years. Major amputations were 50 cases and minor amputations 35 cases. 20 patients (23.5%) were suffered ipsilateral secondary surgery including revised stump. Overall 5-year mortality rate was 18.8% (16 cases). Death rate within 1 year was 8.2% (7 cases), mortality rate within 3 years was 14.1% (12 cases). 5-year mortality rate after major amputation was 20% (10 cases) and after minor amputation was 17.1% (6 cases). It was statistically significant (p<0.05). Patient who underwent more than 2 combined vascular related disease had higher mortality rate than diabetic amputee without combined disease (p<0.05). Conclusion: Mortality rate after major amputation was significant higher than amputation after minor amputation in diabetic patients from our data.
