The authors present a case of subperisoteal orbital hematoma which is extended from subgaleal hematoma. A 15-year-old-male was admitted with a complaint of multiple visual symptoms of left eye following blunt head trauma. He has suffered from Wilson's disease. Several coagulative laboratory findings were abnormal(fibrinogen and coaguation factor V, X). Computed tomography, sonography and magnetic resonance imaging established the subperiosteal orbital extension of subgaleal hematoma into the orbital cavity. Needle aspiration of orbital subperiosteal hematoma was failed but symptoms and signs of the patient were much improved spontaneously following decrease of subgaleal hematoma. The literature is reviewed and management is discussed.

Purpose: Previously, Seoul National University (SNU) prostate cancer (PC) stage calculator was developed to predict the pathological stage of clinically localized PC after radical prostatectomy (RP) in Korean men. We evaluated its generalizability and compared their clinical values with 2013 Partin tables by Korean multicenter cohort. Materials and Methods: Evaluated cohort consisted of 2,607 patients who had clinical stages T1c-T3a PC and were treated with RP at 14 institutions in Korea. After excluding 262 cases with prior hormone or radiation therapy and 604 cases with missing data, 1,741 cases were analyzed. Predictive accuracy was evaluated using the area under the receiver operating characteristic curve (AUC). The agreement between the predicted values with observed outcome was assessed with calibration plot. SNU PC stage calculator was compared with 2013 Partin tables applying to this cohort using DeLong method and decision curve analysis. Results: The accuracies of SNU PC stage calculator was all higher than those of 2013 Partin tables to predict organ-confined disease (0.755 vs. 0.711, p<0.001), extraprostatic extension (0.743 vs. 0.665, p<0.001), seminal vesicle invasion (0.833 vs. 0.764, p<0.001), and lymph node metastasis (0.842 vs 0.760, p=0.019). The observed outcomes were well calibrated with their predicted values by the calculator. Decision curve analyses demonstrated higher net benefits of SNU PC stage calculator compared with 2013 Partin tables.
누전차단기의 충격파 부동작 특성과 EMC 성능 비교분석

본 논문은 누전차단기의 충격파 부동작 특성과 전자기적합성(EMC) 특성비교에 관한 것이다. 국내 규격에서는 충격파 부동작 성능만 확인하지만 국제규격에서는 많은 EMC 항목이 있다. 누전차단기 17종에 대하여 EMC 4항목을 실시한 결과, IEC 61000-4-5에 따른 조합서지 내성에서 9종이 불량이었다. 다른 항목에서는 불량이 발생하지 않았다. 오동작만 발생한 시료 2종에 대하여 충격파 부동작 성능을 평가한 결과 오동작이 발생하지 않았다. 이것으로 보아 EMC와 충격파 부동작 시험은 상관관계가 적으며 보완이 필요함을 알 수 있다.

현재까지 예방접종과 관련된 후천성 혈우병의 보고는 BCG 예방접종과 관련된 보고가 유일하며, 아직까지 인플루엔자 예방접종 후 부작용으로 후천성 혈우병이 보고된 예는 없다. 인플루엔자 예방접종은 노인에서 인플루엔자 감염을 예방하는데 유의하게 효과가 있는 것으로 밝혀져 있으며, 2002년에 국내에서만 대략 700만명이 시행받았다. 수막뇌염, 심낭염 등이 인플루엔자 예방접종 후 발생한 예가 보고 되고 있으나 대단히 드물고, 접종부위의 동통, 권태감, 열감과 같은 전신증상 등이 흔할 뿐 치명적인 부작용은 극히 드문 것으로 알려져 있다. 국내에서 대량으로 접종되고 있는 예방접종 후에 발현된 치명적인 질환을 접하였기에 보고하는 바이며 이는 인플루엔자 예방접종 후 발현된 후천성 혈우병에 관한 학계의 첫 증례보고로 사료된다. Acquired hemophilia is a rare disorder associated with development of factor Ⅷ inhibitors. Acquired inhibitors against factor Ⅷ in nonhemophilic patients are associated with various conditions, including autoimmune diseases, malignancies, the postpartum state, drug reactions. In this report, we described the case of a 65 year-old female, who developed generalized petechiae and gross hematuria due to the appearance of inhibitors against factor Ⅷ following influenza vaccination. She was treated with steroid and cyclophosphamide but retroperitoneal hemorrhage developed, and she died.
