Phyllodes tumors of the breast are rare biphasic fibroepithelial neoplasms that may coexist with breast carcinomas. Herein, we report a case of invasive ductal carcinoma (IDC) within a borderline phyllodes tumor accompanied by extensive ductal carcinoma in situ (DCIS) in the same breast. A 72-year-old woman presented with a palpable lump in the right breast.Mammography showed an oval mass associated with segmental microcalcifications, and breast ultrasound (US) revealed a 2.3 cm oval mass and an associated non-mass lesion. Based on US-guided core needle biopsy, the initial biopsy result of the non-mass lesion suggested DCIS; however, the mass was diagnosed as a fibroepithelial lesion. Preoperative dynamic contrast-enhanced magnetic resonance imaging showed a rim-enhancing oval mass with areas of T2 hyperintensity, accompanied by segmental non-mass enhancement. The mass was highly suspicious for malignancy and was considered imaging-pathology discordant.Subsequently, the patient underwent mastectomy. Histopathological examination of the surgical specimens confirmed a borderline phyllodes tumor with an IDC within the tumor and an extensive intraductal component. The invasive carcinoma component was triplenegative breast cancer. This case highlights the diagnostic challenges of identifying coexisting carcinomas within phyllodes tumors and emphasizes the necessity for increased awareness among radiologists regarding this possibility.

OBJECTIVE:
Under the overcrowding conditions of large emergency departments, the proportion of elderly patients is increasing in Korea. This paper describes the necessity of the preparedness of Korean emergency departments and society for the rapidly aging population.
METHODS:
This was a retrospective observational study. Patients who presented to a tertiary hospital emergency department (ED) in one year were included. The use of medical resources between young adult (≥20 and <65 years of age) and elderly patients (≥65 years of age) was compared.
RESULTS:
This study included 26,712 patients. The young adult group and the elderly group was 15,021 (56.2%) and 11,691 (43.8%), respectively. The ratio of firehouse ambulance visit mode (28.6%) and inter-facility transfer visit mode (18.9%) of the elderly group was higher compared to those of the young adult group (26.4% and 10.6%, P<0.001). The elderly group visited more at daytime (P<0.001). With aging, the admission ratios of the elderly group to the general ward (38.9%) and intensive care unit (13.0%) were higher than the young adult group (9.8% and 4.3%, P<0.001). The mean ED length of stay and mean length of hospitalization of the elderly group was longer than that of the young adult group (P<0.001). The medical cost of the elderly group was approximately three times higher than that of the young adult group.
CONCLUSION
Elderly patients required more emergency medical resources in both the prehospital and hospital stages. Korean emergency departments and society require efforts for not only expansion but also the appropriate use of medical resources in a rapidly aging population.

OBJECTIVE: The aim of this study was to examine the validity of the Korean version of the Hypomania Checklist-32, second revision (HCL-32-R2) in mood disorder patients. METHODS: A total of 454 patients who diagnosed as mood disorder according to Structured Clinical Interview for DSM-IV Axis I Disorders, clinician version (SCID-CV) (bipolar disorder [BD] I, n=190; BD-II, n=72; and major depressive disorder [MDD], n=192) completed the Korean module of the HCL-32-R2 (KHCL-32-R2). RESULTS: The KHCL-32-R2 showed a three-factorial structure (eigenvalue >2) that accounted for 43.26% of the total variance. Factor 1 was labeled “active/elated” and included 16 items; factor 2, “irritable/distractible” and included 9 items; and factor 3 was labeled “risk-taking/indulging” and included 9 items. A score of 16 or more on the KHCL-32-R2 total scale score distinguished between BD and MDD, which yielded a sensitivity of 70% and a specificity of 70%. MDD and BD-II also could be differentiated at a cut-off of 15 with maximized sensitivity (0.67) and specificity (0.66). Cronbach’s alpha of KHCL-32-R2 and its subsets (factors 1, 2, and 3) were 0.91, 0.89, 0.81 and 0.79, respectively. Correlations between KHCL-32-R2 and Montgomery-Asberg Depression Rating Scale, Young Mania Rating Scale and Korean version of Mood Disorder Questionnaire were −0.66 (p=0.41), −0.14 (p=0.9), and 0.61 (p < 0.001), respectively. CONCLUSION: The KHCL-32-R2 may be a useful tool in distinguishing between bipolar and depressive patients in clinical settings.

BACKGROUND: The use of dipeptidyl peptidase-4 (DPP-4) inhibitors is increasing among renal transplant patients with diabetes. However, the glucose-lowering efficacies of various DPP-4 inhibitors and their effects on blood cyclosporine levels have not been fully investigated. We compared the glucose-lowering efficacies of DPP 4 inhibitors and evaluate their effects on the blood levels of cyclosporine in renal transplant recipients with diabetes. METHODS: Sixty-five renal allograft recipients who received treatment with DPP-4 inhibitors (vildagliptin, sitagliptin, or linagliptin) following kidney transplant were enrolled. The glucose-lowering efficacies of the DPP-4 inhibitors were compared according to the changes in the hemoglobin A1c (HbA1c) levels after 3 months of treatment. Changes in the trough levels of the cyclosporine were also assessed 2 months after treatment with each DPP-4 inhibitor. RESULTS: HbA1c significantly decreased in the linagliptin group in comparison with other DPP-4 inhibitors (vildagliptin –0.38%±1.03%, sitagliptin –0.53%±0.95%, and linagliptin –1.40±1.34; P=0.016). Cyclosporine trough levels were significantly increased in the sitagliptin group compared with vildagliptin group (30.62±81.70 ng/mL vs. –24.22±53.54 ng/mL, P=0.036). Cyclosporine trough levels were minimally changed in patients with linagliptin. CONCLUSION: Linagliptin demonstrates superior glucose-lowering efficacy and minimal effect on cyclosporine trough levels in comparison with other DPP-4 inhibitors in kidney transplant patients with diabetes.

Background:Capecitabine and irinotecan combination therapy (XELIRI) has been examined at various dose levels to treat metastatic colorectal cancer (mCRC). Recently, in the Association of Medical Oncology of the German Cancer Society (AIO) 0604 trial, tri?weekly XELIRI plus bevacizumab, with reduced doses of irinotecan (200mg/m2 on day 1) and capecitabine (1600mg/m2 on days 1–14), repeated every 3weeks, has shown favorable tolerability and effcacy which were comparable to those of capecitabine and oxaliplatin (XELOX) plus bevacizumab. The doses of capecit?abine and irinotecan in the AIO trial are considered optimal. In a phase I/II study, XELIRI plus bevacizumab (BIX) as second?line chemotherapy was well tolerated and had promising effcacy in Japanese patients. Methods:The Asian XELIRI ProjecT (AXEPT) is an East Asian collaborative, open?labelled, randomized, phase III clinical trial which was designed to demonstrate the non?inferiority of XELIRI with or without bevacizumab versus standard FOLFIRI (5?lfuorouracil, leucovorin, and irinotecan combination) with or without bevacizumab as second?line chemo?therapy for patients with mCRC. Patients with 20years of age or older, histologically conifrmed mCRC, Eastern Coop?erative Oncology Group performance status 0–2, adequate organ function, and disease progression or intolerance of the ifrst?line regimen will be eligible. Patients will be randomized (1:1) to receive standard FOLFIRI with or with?out bevacizumab (5mg/kg on day 1), repeated every 2weeks (FOLIRI arm) or XELIRI with or without bevacizumab (7.5mg/kg on day 1), repeated every 3weeks (XELIRI arm). A total of 464 events were estimated as necessary to show non?inferiority with a power of 80% at a one?sided α of 0.025, requiring a target sample size of 600 patients. The 95% conifdence interval (CI) upper limit of the hazard ratio was pre?speciifed as less than 1.3. Conclusion:The Asian XELIRI ProjecT is a multinational phase III trial being conducted to provide evidence for XELIRI with or without bevacizumab as a second?line treatment option of mCRC.

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.

PURPOSE: To evaluate the anti-apoptotic effect of the antioxidant reaction of anthocyanin on the prostate in an andropause animal model. MATERIALS AND METHODS: Sprague-Dawley rats were divided into three groups (n=12 in each): control (Group I), andropause (Group II), andropause treated with anthocyanin (Group III). For induction of andropause, Group II and III underwent bilateral orchiectomy. Group III was treated with daily oral anthocyanin (160 mg/kg) for 8 weeks. After 8 weeks, the rats were sacrificed and their blood and prostates were examined pathohistologically and evaluated for oxidative stress and apoptosis. Oxidative stress was assessed by the activity of superoxide dismutase (SOD) and apoptosis in the prostate was identified by terminal deoxyribonucleotidyl transferase-mediated dUTP-digoxigenin nick end-labelling assay. RESULTS: Group II showed markedly increased activity of SOD in serum over that observed in Group I, whereas the rats in Group III showed reduced oxidative stress compared to Group II. Despite no significant differences in prostate weight between Group II and III (p=0.078), the apoptotic index was significantly greater in Group II than Group I, and was significantly lesser in Group III than Group II. CONCLUSIONS: We suggest that the oxidative stress caused by low testosterone may be another inducer of apoptosis, and this apoptosis may partly contribute to the overall apoptosis of the prostate in the andropause animal model. Therefore, anthocyanin supplementation may contribute to preventing excessively rapid cell death by apoptosis in the prostate in an animal model of andropause.

Glacial acetic acid, a caustic substance of strong acidity, can easily be found in our daily lives; sometimes, it is drunk for the purpose of suicide, or it can be misjudged as a beverage. Glacial acetic acid is corrosive and toxic, therefore, even a tiny amount may cause fatal damage, such as gastrointestinal injury and systemic complication. A 66-year-old male patient, based on the wrong information, that glacial acetic acid is a healthy beverage, ingested 250 mL of 99% glacial acetic acid. Complications included gastric perforation, hemolysis, disseminated intravascular coagulation, acute renal failure, and liver dysfunction. We achieved successful treatment through performance of emergency surgery and hemodialysis on the patient, who had ingested a more than fatal dose of glacial acetic acid; herein, we would like to report on the case along with a review of the literature.
