Ovarian cysts in the newborn are uncormnon. Fetal ovarian cysts are being diagnosed with inaeasing fiequency with development of obstetrical sonography. Most of these cysts are found within the first few months of life and have no clinical significance. But, a large ovarian cyst would be founded antenatally with sonography. A large ovarian cyst can cause life-theatening complications during parturition and in the neonatal period. We have experienced a case of fetal ovarian cyst in a 32-year-old primiparous woman with antenatal sonography and report our experience with a brief review of literatures.

Non-Hodgkin's lymphoma frequently involves the kidneys, with previous reports demonstrating approximately a 48 Yo incidence at autopsy. In contrast, lymphoma originating within the kidneys is a rare event, because the renal parenchyma does not have lymphatics. Most common type of primary renal lyrnphoma that calssified by Working formulation and irnmunohistochemistry was diffuse large B-cell, intermediate grade. A 43-year-old woman presented with epigastric discomfort, anorexia, fever, and weight loss. The past rnedical history was unremarkable. On physical examination, she was febrile, and conjunctiva was pale. Lymph node was enlarged and palpated at right inguinal area. But no other lymphadenopathy or hepatosplenomegaly was found. Laboratory study showed WBC 6,900/mm, hemoglobin 6.7g/dL, serum LDH 783IU/L, GFR 31.45 ml/min. The chest X-ray was within normal limit; no mediastinal lympha- denopathy was present. The abdominal X-ray revealed enlargement of right kidney. The abdominal CT scan showed markedly enlarged both kidneys containing inhomogeneous solid masses with poor excretion of intravenous contrast, a few small paraaortic lymphadenopathies, and contour bulging on the pancreas body. A percutaneous renal biopsy was obtained from this patient at the right kidney. Microscopic exarnination showed a diffuse infiltrate of predominantly large lymphoid cells having round to oval vescicular nuclei. Immunohistochemical studies revealed a B-cell-type lymphoma. The tumor was judged to be an intermediate-grade, large-cell, diffused, B-cell-type non-Hodgkin's lymphoma. We report a case of primary bilateral B-cell renal lymphoma in a 43-year-old female patient with review of the literature.

Background:
and Purpose To evaluate the outcome events and bleeding complications of the European Society of Cardiology (ESC) guideline-matched oral anticoagulant therapy for patients with acute ischemic stroke and atrial fibrillation (AF).
Methods:
Patients with acute ischemic stroke and AF from a nationwide multicenter registry (Korean ATrial fibrillaTion EvaluatioN regisTry in Ischemic strOke patieNts [K-ATTENTION]) between January 2013 and December 2015 were included in the study. Patients were divided into the ESC guideline-matched and the non-matched groups. The primary outcome was recurrence of any stroke during the 90-day follow-up period. Secondary outcomes were major adverse cerebrovascular and cardiovascular events, ischemic stroke, intracranial hemorrhage, acute coronary syndrome, allcause mortality, and major hemorrhage. Propensity score matching and logistic regression analyses were performed to assess the effect of the treatments administered.
Results:
Among 2,321 eligible patients, 1,126 patients were 1:1 matched to the ESC guidelinematched and the non-matched groups. As compared with the non-matched group, the ESC guideline-matched group had a lower risk of any recurrent stroke (1.4% vs. 3.4%; odds ratio [OR], 0.41; 95% confidence interval [CI], 0.18 to 0.95). The risk of recurrent ischemic stroke was lower in the ESC guideline-matched group than in the non-matched group (0.9% vs. 2.7%; OR, 0.32; 95% CI, 0.11 to 0.88). There was no significant difference in the other secondary outcomes between the two groups.
Conclusions
ESC guideline-matched oral anticoagulant therapy was associated with reduced risks of any stroke and ischemic stroke as compared with the non-matched therapy.

BACKGROUND AND PURPOSE: The clinical implications of echocardiography findings for long-term outcomes in atrial fibrillation (AF)-related stroke patients are unknown. METHODS: This was a substudy of the Korean ATrial fibrillaTion EvaluatioN regisTry in Ischemic strOke patieNts (K-ATTENTION), which is a multicenter-based cohort comprising prospective stroke registries from 11 tertiary centers. Stroke survivors who underwent two-dimensional transthoracic echocardiography during hospitalization were enrolled. Echocardiography markers included the left-ventricle (LV) ejection fraction (LVEF), the left atrium diameter, and the ratio of the peak transmitral filling velocity to the mean mitral annular velocity during early diastole (E/e′ ratio). LVEF was categorized into normal (≥55%), mildly decreased (>40% and <55%), and severely decreased (≤40%). The E/e′ ratio associated with the LV filling pressure was categorized into normal (<8), borderline (≥8 and <15), and elevated (≥15). Kaplan-Meier and Cox regression analyses were performed for recurrent stroke, major adverse cardiac events, and all-cause death. RESULTS: This study finally included 1,947 patients. Over a median follow-up of 1.65 years (interquartile range, 0.42–2.87 years), the rates of recurrent stroke, major adverse cardiac events, and all-cause death were 35.1, 10.8, and 69.6 cases per 1,000 person-years, respectively. Multivariable analyses demonstrated that severely decreased LVEF was associated with a higher risks of major adverse cardiac events [hazard ratio (HR), 3.91; 95% confidence interval (CI), 1.58–9.69] and all-cause death (HR, 1.95; 95% CI, 1.23–3.10). The multivariable fractional polynomial plot indicated that recurrent stroke might be associated with a lower LVEF. CONCLUSIONS: Severe LV systolic dysfunction could be a determinant of long-term outcomes in AF-related stroke.

Background:
and Purpose The congestive heart failure, hypertension, age, diabetes, previous stroke/transient ischemic attack (CHA2DS2-VASc) and hypertension, abnormal renal/liver function, stroke, bleeding history or predisposition, labile international normalized ratio, elderly, drugs/alcohol (HAS-BLED) scores have been validated in estimating the risks of ischemic stroke and major bleeding, respectively, in patients with atrial fibrillation (AF). This study investigated stroke-specific predictors of major bleeding in patients with stroke and AF who were taking oral anticoagulants (OACs).
Methods:
Subjects were selected from patients enrolled in the Korean ATrial fibrillaTion EvaluatioN regisTry in Ischemic strOke patieNts (K-ATTENTION) nationwide multicenter registry between 2013 and 2015. Patients were excluded if they were not taking OACs, had no brain imaging data, or had intracranial bleeding directly related to the index stroke. Major bleeding was defined according to International Society of Thrombosis and Haemostasis criteria. Cox regression analyses were performed to assess the associations between clinical variables and major bleeding and Kaplan-Meier estimates were performed to analyze event-free survival.
Results:
Of a total of 3,213 patients, 1,414 subjects (mean age of 72.6 years, 52.5% males) were enrolled in this study. Major bleeding was reported in 34 patients during the median follow-up period of 1.73 years. Multivariable analysis demonstrated that initial National Institutes of Health Stroke Scale scores (hazard ratio [HR] 1.07, p=0.006), hypertension (HR 3.18, p=0.030), persistent AF type (HR 2.51, p=0.016), and initial hemoglobin level (HR 0.74, p=0.001) were independently associated with major bleeding risk. Except for hypertension, these associations remained significant after adjusting for the HAS-BLED score. Intracranial atherosclerosis presented a trend of association without statistical significance (HR 2.21, p=0.050).
Conclusions
This study found that major bleeding risk was independently associated with stroke-specific factors in anticoagulated patients with stroke and AF. This has the clinical implication that baseline characteristics of patients with stroke and AF should be considered in secondary prevention, which would bring the net clinical benefit of balancing recurrent stroke prevention with minimal bleeding complications.

Since laparoscopic liver resection was first introduced in 2001, Korean surgeons have chosen a laparoscopic procedure as one of the treatment options for benign or malignant liver disease. We distributed and analyzed a nationwide questionnaire to members of the Korean Laparoscopic Liver Surgery Study Group (KLLSG) in order to evaluate the current status of laparoscopic liver resection in Korea. Questionnaires were sent to 24 centers of KLLSG. The questionnaire consisted of operative procedure, histological diagnosis of liver lesions, indications for resection, causes of conversion to open surgery, and postoperative outcomes. A laparoscopic liver resection was performed in 416 patients from 2001 to 2008. Of 416 patients, 59.6% had malignant tumors, and 40.4% had benign diseases. A total laparoscopic approach was performed in 88.7%. Anatomical laparoscopic liver resection was more commonly performed than non-anatomical resection (59.9% vs 40.1%). The anatomical laparoscopic liver resection procedures consisted of a left lateral sectionectomy (29.3%), left hemihepatectomy (19.2%), right hemihepatectomy (6%), right posterior sectionectomy (4.3%), central bisectionectomy (0.5%), and caudate lobectomy (0.5%). Laparoscopy-related serious complications occurred in 12 (2.8%) patients. The present study findings provide data in terms of indication, type and method of liver resection, and current status of laparoscopic liver resection in Korea.
