정영복,김진수,정호중,정평호 대한슬관절학회 2002 대한슬관절학회지 Vol.14 No.2
목적: 후방십자인대 단독 손상 환자에 있어서 보존적 치료를 시행 후 결과를 알아보고자 하였다. 재료 및 방법: 1999년 8월부터 2001년 12월까지 본원에 내원 하여 후방십자인대 단독 손상으로 진단된 11례에 대해서 보존적 치료를 시행하였다. 초기 진단은 이학적 검사와 Telos 기구를 이용한 후방전위 사진(push stress view)으로 하였고 추시 평가는 전향적으로 하였으며 6주, 3개월, 6개월, 1년, 그 후 매년마다 이학적 검사와 International Knee Documentation Committee(IKDC) score와 Orthopadishe Arbeitsguppe Knie(OAK) score를 이용한 임상적 평가를 하는 것을 기준으로 하였으며 6개월 후에는 후방 전위 사진과 단순 전후 및 좌우 방사선을 시행하였다. 치료방법은 6주간 슬관절 완전 신전 상태로 후방 전위 방지 지지대를 부착한 하지 부목 후 6주간 슬관절 후방 전위 방지 보조기를 시행하였다. 이들의 평균 추시 시간은 17.5개월(7~35)이었다. 결과: 11례중 2례에서는 후방전위에 후 외측 회전 불안정성 동반이 발견되어 수술적 치료를 시행하였으며 보존적 치료를 유지하였던 9례에서는 최근 추시 임상적 평가에서 OAK score상 평균 93.2점, IKDC score상 A가 5례, B가 4례이었다. 결론: 동반손상이 없는 후방십자인대 단독 손상에 있어서 보존적 치료가 일차적 치료 방법으로 생각되며 향후 불안정성의 진행과 이차적 퇴행성관절염의 발생 여부 및 상관 관계에 대해서 장기적 추시 관찰 예정이다. Purpose: We assessed prospectively the results of acute, isolated, posterior cruciate ligament injuries treated conservatively. Materials and Methods: Between August 1999 and December 2001, the study population consited of 11 patients. The patients were treated conservatively and were prescribed full extension long leg splint with posterior tibial support for 6 weeks and then posterior tibial support brace for another 6 weeks. Patients completed a sujetive and objective evaluation at 6 weeks, 3 month, 6 month and each year for an average of 17.5 months. Results: Two patients underwent reconstructive surgery because of combined posterolateral rotatory instability. The nine patients were treated conservatively, the mean Orthopadishe Arbeitsguppe Knie score was 93.2 points. International Knee Documentation Committee score in 5 patients was A and 4 patients was B. Conclusion: Our study suggests that patients with acute, isolated posterior cruciate ligament injuries treated conservatively may get good clinical results, but we are planning a long term follow-up evaluation to reveal change in laxity, incidence of arthrosis and their correlation.

Abstract Pleiotropic effect on rice grain quality characters of gene controlling amylose content(AC) or alkali digestibility(ADV) of rice grain was tested using near isogenic line(NIL). Successive selfing of hetero plant for AC or ADV was adopted for NIL development. Two sets of NIL for AC were selected in F6 lines, and one set of NIL for ADV was identified in F6lines in this experiment. No difference in protien content, ADV, gel consistency, chroma value of brown rice and grain weight was found between medium and low AC NILs. Among cooking characteristics only iodine value of residual cooking water of low AC line was significantly higher than medium AC line. Medium AC line showed higher maximum and breakdown viscosity, and lower final, consistency and setback viscosity compared with low AC line in visco-gelatinization characters. Values for adhesiveness, gumminess, viscousness and balance of cooked rice grain were lower, but stickiness was higher in low AC line compared with medium AC line. High and low ADV NILs showed different protein content and chroma value a. Rice flour of high ADV line indicated lower value in initial pasting temperature, maximum and breakdown viscosity, but higher value in setback viscosity among visco-gelatinization characters compared with low ADV line. It can be concluded that NILs for AC or ADV selected in this experimnet were differed in several characteristics related rice grain quality.

Objective : To compare peri-operative any symptomatic stroke after carotid angioplasty and stenting (CAS), based on the application or absence of a cerebral protection device. Methods : A systematic literature review using PubMed, Embase, and the Cochrane Central was done across an online data base from January 1995 to October 2016. Procedures which were performed due to carotid dissection or aneurysm, procedures using covered stents or conducted in an emergency, were excluded. The primary endpoint was perioperative any symptomatic stroke within 30 days after the procedure. A fixed effect model was used in cases of heterogeneity less than 50%. Results : In the 25 articles included in this study, the number of stroke events was 326 (2.0%) in protected CAS and 142 (3.4%) in unprotected CAS. The use of cerebral protection device significantly decreased stroke after CAS (odds ratio [OR] 0.633, 95% confidence interval [CI] 0.479-0.837, p=0.001). In the publication bias analysis, Egger's regression test disclosed that the intercept was -0.317 (95% CI -1.015-0.382, p=0.358). Regarding symptomatic patients (four studies, 539 CAS procedures), the number of stroke was six (1.7%) in protected CAS and 11 (5.7%) in unprotected CAS. The protective effect against stroke events by cerebral protection device did not have a statistical significance (OR 0.455, 95% CI 0.151-1.366, p=0.160). Conclusion : The use of protection device significantly decreased stroke after CAS. However, its efficacy was not demonstrated in symptomatic patients. Routine use of protection device during CAS should be critically assessed before mandatory use.
CASE REPORT : The Olfactory Groove Schwannoma Attached to the Cribriform Plate: A Case Report
( Deok Young Kim ),( Pyeong Ho Yoon ),( Jeong Hae Kie ),( Kook Hee Yang ) 대한뇌종양학회 대한신경종양학회 2015 Brain Tumor Research and Treatment Vol.3 No.1
The olfactory groove schwannoma is a quite rare tumor. We report a case of a 49-year-old woman with an olfactory groove schwannoma attached to the cribriform plate without olfactory dysfunction. She had no specific neurological symptoms other than a headache, and resection of the tumor showed it to be a schwannoma. About 19 months after the operation, a follow-up MRI showed no evidence of tumor recurrence. Surgical resection through subfrontal approach could be one of the curative modality in managing an olfactory groove schwannoma. An olfactory groove schwannoma should be considered in the differential diagnosis of anterior skull base tumors.
