Primary malignant melanoma of the vagina is extremely rare, accounting for 3% of all primary malignant tumor of the vagina and 0.3~1% of all malignant melanomas in the female. The amelanotic melanoma of the vagina showing no melanin granules on histological examination is exceedingly rare, accounting for only about 10% of all melanoma of the vagina. The amelanotic melanoma of the vagina is often difficult to differentiate from non-epithelial malignant tumor because of the minimal number of melanin granules. We describe a case of primary amelanotic melanoma of the vagina, which was initially suspected to be a non-epithelial malignant tumor, especially malignant peripheral nerve sheath tumor (MPNST), but was correctly diagnosed by HMB-45 antibody and S-100 protein immunohistochemical staining. So we present this case with a brief review of literature.

연구목적 결핵환자 중 우울증 고위험 환자와 저위험 환자의 비교연구를 통해 결핵환자의 우울증 위험요인을 밝히고자 했다. 방 법 57명의 결핵환자를 대상으로 벡 우울 검사 2판을 이용하여 우울증상을 평가하였다. 우울증 고위험군과 저위험군으로 나누어 이분형로지스틱회귀분석 및 계산도표를 작성하였다. 결 과 신체비만지수가 낮아질수록 우울증 고위험군에 속할 위험은 높았다. 결핵치료 임의중단력이 있을 경우 우울증 고위험군에 속할 위험은 6배 높았다. 우울증 과거병력이 있는 경우 우울증 고위험군에 속할 위험은 25배 높았다. Original C-index는 0.789였고 bias corrected C-index는 0.754로 상당한 일치를 보였다. 결 론 낮은 신체비만지수, 결핵치료 임의중단력, 우울증 과거병력은 결핵환자의 우울증 위험요인임을 밝혔다. 이는 결핵환자에 대한 정신건강의학과적 개입 및 치료를 위한 근거자료가 될 것이다. Objectives : This study aimed to investigate the risk factors of depression for patients with tuberculosis(TB). Methods : A total of 57 patients with TB were recruited. All participants completed the Becks Depression Inventory-II for evaluating depressive symptoms. The risk factor for depression was analyzed by binary logistic regression analysis. Nomogram was performed for probability of depression. Results : Low body mass index(BMI, OR 0.801, 95% CI 0.65, 0.98), interruption of treatment for TB(OR 5.908, 95% CI 1.19, 29.41), past history of depression(OR 24.653, 95% CI 1.99, 308.44) were associated with increased risk for depression. The calibration curve for predicting probability of survival showed a good agreement between the nomogram and actual observation(Original C-index=0.789, bias corrected C-index=0.754). Conclusions : The result of the present study indicate that low BMI, interruption of treatment for TB, and past history of depression were risk factors for depression in patients with TB. The psychiatric intervention may be needed to prevent depression if the patients with TB have risk factor during treatment for TB.

Placenta accreta is a rare complication of pregnancy with high rates of maternal morbidity and mortality. Although the incidence of placenta accreta was rare in the past, it is sharply rising as a result of the dramatic increases in the cesarean section rate. Hysterectomy is the most effective way to manage the placenta accreta in the majority of cases. While in many situations hysterectomy will remain appropriate, there are other management options available involving conservative approaches. In this article, we report our experience of a successful conservative treatment using methotrexate and misoprostol to a patient in whom the whole placenta was not detachable from the uterus due to placenta increta.

난소에서 일차적으로 발생하는 섬유종은 전체 난소 종양의 약 4%를 차지한다. 난소 섬유종은 대부분 양성이나 1% 이하에서 mitotic activity를 지닌다. Prat등은 난소에 생기는 섬유성 종양의 예후를 예측하는 방법으로 10고배율 소견당 세포 분열상의 수를 기준으로 세포성 섬유종과 섬유육종으로 분류하였다. 세포성 섬유종은 10 고배율 소견당 세포분열상의 소견이 1-3개이며 종양의 유착이나 파열이 없는 한 수술 후 재발을 잘하지 않는다. 그리고 10고배율 소견당 세포 분열 상 소견이 4개 이상이면 예후가 극히 불량한 섬유육종으로 분류하였다. 두 경우 모두에서 양성 섬유종보다 종양의 크기가 더 크며 더 불량한 예후를 보이게 된다. 저자들은 본원 산부인과에서 시험 개복술 결과 난소에서 일차적으로 기인한 난소 섬유육종 2예를 경험하였기에 간단한 문헌 고찰과 함께 보고하는 바이다. Fibromatous tumors of the ovary are considered to originate from specialized ovarian stromal cells and account for approximately 4% of all ovarian neoplasms. These are mostly benign tumors with less than 1% having increased mitotic activity. If 1 to 3 mitoses per ten high power fields (HPF) are present, the tumor is considered low grade, and is called a cellular fibroma. If greater than 3 mitoses per 10 HPF are present, it is considered as a fibrosarcoma. In both cases the tumor is usually larger than a benign fibroma and carries a worse prognosis. We have met two cases of large ovarian fibrosarcoma and report these cases with the brief review of literatures.

This study set out to compare and analyze the strategy used by excellent male curling teams and non-excellent ones in an attempt to see if there were any differences between them based on the idea that strategy affect the results of games. For that purpose, total ten curling male teams that competed in the 2003 National Winter Athletic Games were chosen. Four of them were defined excellent while the rest six non-excellent. Among the total 1,385 strategy used by the 40 players of the ten teams, 1,124 that were identified as successful were selected. A 6㎜ Camcorder was used to tape the games, which were played using a VTR. The game data was put down on the recording document by the investigator in order to increase the validity. Based on the data recorded on the document, the frequencies were presented in percentage and x² tested according to the research purposes. Those research methods and processes led to the following results: First, there were significant differences between the excellent and non-excellent teams in strategy. Among the subcategories of the strategy, there were significant differences between the two groups in the draw strategy. Second, there were found significant differences in the strategy by ends during the early ends including End 1, 2, and 3 out of the ten ends between the two groups. Third, the two group of teams showed significant differences in the skip strategy among the strategy by positions.
