Malignant germ cell tumors occur in children and young women in reproductive age, of all the germ cell malignancies, only pure dysgerminomas had a high cure rate prior to 1970. This was due to the exquisite radiosensitivity of these tumors. Multiple-agent chemotherapy has dramatically improved the pmgnosis of patients with malignant ovarian germ cell tumors. Clinicopathological analysis was performed on 21 cases of malignant germ cell tumors of the ovary, 9 cases at the department of Obstetrics & Gynecology, Kyung-pook National University Hospital, 4 cases, at the department of Obstetrics and Gynecology, Dong-guk University Kyungju Hospital and 8 cases, at the department of Obstetrics and Gynecology, Dae-gu Fatima Hospital during the period 10 years from July. 19S8 to June. 1997 The results were summarized as follows: 1. The mean age of the patients was 21.8 years old, ranging from 10 to 61 years old. 2. Main initial symptoms were abdominal distension(33.3%), abdominal mass palpation(33.3%), abdominal pain(28.6%), amenorrhea(4.8%) in order. 3. Histologically, the tumors were classified as immature teratoma(57.1%), dysgerminoma(19%), mixed germ cell tumor(9.5%), endodermal sinus tumor(9.5%), embryonal cell carcinoma(4.8%). 4, According to FIGO classification Stage I was the most prevalent(57.1%) at the time of diagnosis while Stage III was forward in 48.6%, Stage II in 9.5%, and no Stage IV, 5. The 5-year survival rate was 80.4% and three patients have died of malignancy and the other 18 patients live without disease from 11 to 102 months, with a median follow-up of 34.2 months. 6. Prognostic factors of malignant germ cell tumors in this study were the clinical stage, the presence of ascites and the residual tumor mass.

Hemophagocytic syndrome (HPS) is a rare but potentially life-threatening disease in kidney transplant recipients, and is caused by systemic proliferation of macrophages actively phagocytizing other blood cells in the bone marrow, lymph nodes, and the spleen.Here, we report a 40-year-old male kidney transplant recipient who presented with fever, bicytopenia, and elevated liver enzymes 2 months after transplantation. Given that cytomegalovirus antigenemia and real-time polymerase chain reaction tests were positive, liver biopsy was performed under an assumption of cytomegalovirus-induced hepatitis. Hepatic histology revealed multifocal microabscess with cytomegalovirus inclusion bodies, marked Kupffer cell hyperplasia, and erythrophagocytosis by activated macrophages. As laboratory findings such as hyperferritinemia, elevated serum lactate dehydrogenase, low natural killer cell activity, and high soluble interleukin-2 receptor were also compatible with HPS, the recipient was diagnosed as having cytomegalovirus-induced hepatitis combined with reactive HPS. Following intravenous ganciclovir therapy with continuous administration of tacrolimus and corticosteroid, the symptoms resolved and laboratory findings were normalized. As far as we know, this is the first report of cytomegalovirus-induced hepatitis combined with reactive HPS in a kidney transplant recipient that is diagnosed by liver biopsy.

PURPOSE: We have done this retrospective study to know the relative incidence and clinical manifestations of organic acidopathies in Korea during 8 years(from Jul. 1997 to May 2005). This results of organic acid analysis of 1,787 patients were compared with the results of organic acid analysis that were published three years ago. METHODS: The results of quantitative organic acid analysis of samples of 1788 patients, referred from Jul. 1997 to May 2005, were analyzed retrospectively according to four age group(-2 mon, 3 mon-2 years, 3-12 years) and major clinical manifestations. Quantification of 83 organic acids was done with gas chromatography and mass spectometry. RESULTS: We diagnosed 470 patients with 27 diseases of organic acid metabolism during this study period. Diseases found more than 10 cases are cytosolic 3-ketothiolase deficiency, mitochondrial respiratory chain disorders, PDHC deficiency, mitochondrial 3-ketothiolase deficiency, glutaric aciduria type II, biotinidase deficiency, methylmalonic aciduria and propionic aciduria. Other diseases were diagnosed in less than 10 cases. CONCLUSION: Though the incidence of individual organic acidemia is low, the overall incidence of organic acidemia as a whole seems to be relatively high in Korea. Compared with the results of organic acid analysis that were reported three years ago, we couldn't find a new disease and the difference of the relative incidences of high incident diseases. We were apprehensive of the errors that was owing to the short study period(3 years), but the relative incidences of our study(8 years) were similar to the results of organic acid analysis that were reported three years ago.

BACKGROUND: This study was conducted to analyze the current system for allocation of deceased donor kidney transplantation in Korea, which includes an incentive regulation for candidates registered at the Hospital-based Organ Procurement Organization (HOPO). METHODS: Between January 2011 and November 2016, there were 2,655 deceased donors in Korea. During the same period, there were 21,247 current candidates and recipients of kidney, pancreas and simultaneous pancreas-kidney transplants. We analyzed data from all of these donors, candidates, and recipients. RESULTS: Mean waiting times for organ allocation of each priority differed significantly (2nd priority group, 1,701±974 days; 3rd priority group, 1,316±927 days; 4th priority group, 2,077±1,207 days). Additionally, HOPO candidates/deceased donor ratios were very different from each other (maximum, 49; minimum, 0.6). The number of deceased donors in region 1, 2, and 3 were 1,623, 429, and 603, respectively, while the number of transplantations in each region was 3,095, 597, and 1,165, respectively. The candidates registered at region 1 HOPO moved the longest distances on average for transplantation, and this value differed significantly different from that of other regions (56.18±91.9 km vs. 24.66±28.0 km vs. 26.20±37.3 km, P<0.05). CONCLUSIONS: The incentive system of current allocation system for deceased donor kidney in Korea does not coincide with the purpose of the ‘Declaration of Istanbul’ and unnecessary social costs have occurred. Therefore, we should make an effort to change our current allocation system to the geographic sequence of organ allocation system.

Hypoglycemic hemiplegia is an under-recognized manifestation of hypoglycemia and mimics cerebrovascular dis-ease, especially in elderly patients. We report a 70-year-old diabetic woman with hypoglycemic hemiplegia, whose dif-fusion- and perfusion- weighted images showed large cortical high signal intensities and hypoperfusion of the right hemisphere during the period of hypoglycemia. We suggest that the regional cerebral blood redistribution and selective vulnerability in hypoglycemia are responsible for the laterality of neurological deficits observed during hypoglycemic episodes.

Objectives: ：The aim of this study was to determine how the efficacy and compliance of positive airway pressure (PAP) varies depending on the depressive symptom with obstructive sleep apnea (OSA). Methods: ：We collected data about baseline Apnea-Hyponea Index (AHI), sleep and mood state and demographic information from 125 obstructive sleep apnea patients prior to the start of positive airway pressure treatment. The Apnea-Hyponea Index and daytime sleepiness were examined as indicators of efficacy of positive airway pressure and daily average usage time and the utilization rate (%) for more than 4 hours were calculated as indicators of compliance of positive airway pressure at the time of 1, 3 or 9 months after the start of positive airway pressure. Repeated-measures ANOVA and linear mixed model (LMM) with adjusting age, body mass index and baseline Insomnia severity index were used for revealing any significant differences between groups over time passed. Results: ：This difference was confirmed at 9 months after starting positive airway pressure, between the two groups and the usage rate for more than 4 hours in depressive group was lower than that in non-depression group (56.2% vs. 67.5%). Conclusions ：We demonstrated that there would be a difference in the compliance of positive airway pressure among patients with obstructive sleep apnea according to depressive state. Therefore, we suggest evaluating depressive symptoms in patients with obstructive sleep apnea before starting positive airway pressure, to increase the compliance of the positive airway pressure, which is essential to maintain the efficacy of the positive airway pressure.

Primary pulmonary meningioma is a rare disease, and chordoid meningioma is an uncommon variant of meningioma in the central nervous system (CNS) with a high recurrence rate. We report a case of primary pulmonary chordoid meningioma that presented as a solitary pulmonary nodule (SPN). The SPN was resected by thoracoscopic wedge resection and was revealed to have characteristics of chordoid meningioma. After confirming the absence of a meningioma in the CNS by brain imaging, the nodule was diagnosed as a primary pulmonary chordoid meningioma. The patient remained disease-free after 26 months postoperatively. To our knowledge, this is the third case of primary pulmonary chordoid meningioma to be reported.

Transplantation of the horseshoe kidney can be performed en bloc or split into 2 grafts according to the vascular anomaly and the existence of the urinary collecting system in isthmus. From 2011 to 2014, there were 3 horseshoe kidney transplantations in Korea and transplantations were performed at 2 different centers. The transplantations were carried out successfully for all recipients without complications. All recipients have shown good graft kidney function after transplantation. No severe complication was revealed during follow-up period. We described the surgical technique used in the en bloc method to overcome various vascular anomalies and difficulties in choosing cannulation site and postoperative complications. En bloc transplantation of a horseshoe kidney is a useful strategy for patients with end-stage renal disease, and can provide favorable outcomes compared to the transplantation of a normal kidney.

BACKGROUND: The aim of this study is to evaluate the feasibility of living donor liver transplantation (LDLT) using an right posterior sector (RPS) graft selected by liver volumetry of living donors. METHODS: From April 2008 to August 2014, 132 LDLTs were performed in our hospital. Of these, 20 recipients (15.1%) received an RPS graft. Perioperative data of LDLTs using an RPS graft were analyzed retrospectively. RESULTS: Mean of the Model for End-stage Liver Disease score of the 20 recipients was 12.1+/-6.2. The mean right liver volume was 72.4%+/-3.1% of total liver volume (TLV) and the mean volume of RPS was 38.2%+/-5.3% of TLV. Anatomical anomalies were found in the portal vein (PV) of 14 donors (70%), in the hepatic artery of one donor (5%), and bile duct of seven donors (35%). All donors were discharged with normal liver function. Two donors (10%) developed bile leakage after RPS donation. None of the recipients experienced complication associated with hepatic artery and PV anastomosis. One recipient had in-hospital mortality due to pneumonia. The remaining 19 recipients were discharged with good graft function. Four recipients (20%) developed biliary stricture and one (5%) had a liver abscess during follow-up. CONCLUSIONS: The RPS donor had a high incidence of abnormal anatomy of PV. LDLT using an RPS graft might have high incidence of biliary complications. We think that selection of an RPS graft from a donor with an inappropriately large right lobe volume could expand the donor pool and be a feasible option in LDLT.
