A giant cell tumor of bone is a benign bone tumor, but has very high local recurrence rate and, very rarely metastasizes to the lung or a distant area. We report a case of a 29-year-old male patient presenting with a metastatic giant cell tumor of the soft tissue of the chest wall, who underwent a total resection of the radius for recurrence of the giant cell tumor. The tumor was not related to any bony structure of the thorax. We resected the tumor with a wide surgical margin. No evidence of malignancy was seen in the frozen and permanent pathological report.

Glomerulonephritis associated with malignancy is deemed to be paraneoplastic glomerulonephritis. Myelodysplastic syndrome (MDS) is a group of heterogeneous clonal hematopoietic stem cell disorders characterized by impaired hematopoietic cell differentiation and cytopenia. The pathophysiology of MDS is thought to be immune-mediated in part. A few reports have documented various forms of glomerulonephritis in patients with MDS and suggested that immune dysregulation is important in the development of paraneoplastic glomerulonephritis. Here, we report a patient with MDS and refractory anemia with excess blast-2 accompanied by minimal change nephrotic syndrome. The patient was treated with prednisolone, and the nephrotic-range proteinuria and pancytopenia improved markedly.

Down syndrome critical region 1 (DSCR1), an oxidative stress-response gene, interacts with calcineurin and represses its phosphatase activity. Recently it was shown that hydrogen peroxide inactivates calcineurin by proteolytic cleavage. Based on these facts, we investigated whether oxidative stress affects DSCR1-mediated inactivation of calcineurin. We determined that overexpression of DSCR1 leads to increased proteolytic cleavage of calcineurin. Convertsely, knockdown of DSCR1 abolished calcineurin cleavage upon treatment with hydrogen peroxide. The PXIIXT motif in the COOH-terminus of DSCR1 is responsible for both binding and cleavage of calcineurin. The knockdown of overexpressed DSCR1 in DS fibroblast cells also abrogated calcineurin proteolysis by hydrogen peroxide. These results suggest that DSCR1 has the ability to inactivate calcineurin by inducing proteolytic cleavage of calcineurin upon oxidative stress.

The aim of this study was to determine the normal value of brachial-ankle pulse wave velocity (baPWV) and carotid-femoral pulse wave velocity (cfPWV) according to age group, gender, and the presence of cardiovascular risk factors in healthy Koreans, and to investigate the association between PWV and risk factors such as prehypertension, dyslipidemia, smoking, and obesity. We measured an arterial stiffness in 110 normal subjects who were 20 to 69 yr-old with no evidence of cardiovascular disease, cerebrovascular accident or diabetes mellitus. The mean values of baPWV and cfPWV were 12.6 (+/-2.27) m/sec (13.1+/-1.85 in men, 12.1+/-2.51 in women; P=0.019) and 8.70 (+/-1.99) m/sec (9.34+/-2.13 in men, 8.15+/-1.69 in women; P=0.001), respectively. The distribution of baPWV (P<0.001) and cfPWV (P=0.006) by age group and gender showed an increase in the mean value with age. Men had higher baPWV and cfPWV than women (P<0.001). There was a difference in baPWV and cfPWV by age group on prehypertension, dyslipidemia, current smoking, or obesity (P<0.001). In multiple linear regression, age and prehypertension were highly associated with baPWV and cfPWV after adjustment for confounding factors (P<0.001). The present study showed that baPWV and cfPWV are associated with age, gender, and prehypertension in healthy Koreans.

OBJECTIVE: To evaluate the correlation of the expression of E-cadherin, alpha-catenin, beta-catenin and the clinicopathological features in endometrial cancer (EC) and atypical complex endometrial hyperplasia (ACEH). METHODS: Immunohistochemical (IHC) staining of E-cadherin, alpha-catenin, beta-catenin was performed in tissues of 6 ACEHs, 44 endometrioid ECs. We analyzed the correlation of the expression of IHC staining with the prognostic factors according to tumor stage of ACEH and EC, histopathologic grade, and myometrial invasion. RESULTS: According to tumor stage, reduced E-cadherin expression and abnormal alpha-catenin expression were observed more frequently in advanced stage (reduced E-cadherin: ACEH 0%, stage I-II 47.2%, stage III-IV 62.5%, p=0.050; abnormal alpha-catenin: ACEH 0%, stage I-II 27.8%, stage III-IV 62.5%, p=0.035). All of the IHC staining showed no correlation with the depth of myometrial invasion but showed correlation with presence of myometrial invasion (reduced E-cadherin: invasion(-) 14.3%, invasion(+) 66.7%, p =0.001; abnormal alpha-catenin: invasion(-) 7.1%, invasion (+) 46.0%, p=0.010; abnormal beta-catenin: invasion(-) 7.1%, invasion(+) 63.0%, p=0.000). According to histological differentiation only abnormal beta-catenin expression shows relationship with histopathologic grade (grade 1:23.1%, grade 2:60%, grade 3:62.5%, p=0.039). CONCLUSION: Expression of E-cadherin and alpha-catenin showed significantly more reduced expression in EC than in ACEH, and more reduced expression in advanced stage, myometrial invasion and high histopathologic grade. And alpha-catenin showed more frequent abnormal expression in advanced stage, myometrial invasion and beta-catenin showed more frequent in myometrial invasion, high histopathologic grade significantly. These results suggests that the expression of E-cadherin and alpha-catenin, beta-catenin in EC and ACEH could be related to prognosis of the tumor.

Cerebrovascular disorders (infarction and intracranial hemorrhage), otherwise collectively referred to as stroke, are an uncommon and feared complication of pregnancy. Collectively, these disorders contribute up to 12% of all maternal deaths. Because of the common presentation with seizures, hypertension, proteinuria, and visual disturbance there has been diagnostic confusion with eclampsia, especially when cerebrovascular disorders occur antepartum or intrapartum. This case is intended to assist the clinician with clues for prompt diagnosis and therapy for this uncommon and unpreventable medical complication of pregnancy.

OBJECTIVE: There is much research on risk factors of suicide, but studies about what can play a protective role on suicide are limited. This study was conducted to investigate the impact of depression and emotional intelligence on suicidal ideation of patients with depression. We focused more on the role of emotional intelligence as a protective factor. METHODS: The participants (n=100) underwent a psychiatric interview which included the Mini International Neuropsychiatric Interview and the Columbia University Suicide Severity Rating Scale (C-SSRS). Beck's Depression Inventory (BDI) was also completed. For measuring emotional intelligence, both a self-report questionnaire (the Adult Emotional Quotient Test, AEQT) and an objective measurement based on ability model (Emotional Literacy) were conducted. RESULTS: In linear regression analysis, depressive symptom score was significantly associated with suicidal ideation. It was also shown that 'emotional expression' of AEQT and 'emotion perception' of Emotional Literacy are significantly associated with suicidal ideation. CONCLUSION: Against our expectation that emotional intelligence would be a protective factor on suicidal ideation, emotional expression and emotion perception might rather be a risk factor for suicidal ideation. The limitations of this study and suggestions for further research are also discussed.

BACKGROUND: Although stress-induced cardiomyopathy (SCMP) is reported to be more common in women, little is known about gender differences in patients with SCMP. The aim of the study was to describe clinical features of patients with SCMP according to gender. METHODS: One hundred and three patients diagnosed with definite SCMP at a single tertiary institute from January 1997 to August 2014 were enrolled. SCMP was more common in women than in men. RESULTS: Age at presentation was not significantly different between the two groups (p = 0.758). Preceding physical stress, especially acute medical illness, was more common in male patients (p = 0.014), whereas emotional stress was more common in female patients (p = 0.016). Severity of medical illness classified by the Acute Physiology and Chronic Health Evaluation (APACHE) II score at the time of SCMP diagnosis was not significantly different between men and women (p = 0.752). Clinical characteristics, including symptoms, laboratory and electrocardiographic findings, were similar. However, pump failure was more severe in men (p = 0.024). Clinical outcomes were not statistically different (p = 0.220). Preceding physical stress and lower left ventricular systolic function after 2 months were independent risk factors for all-cause mortality for both genders. Women with an APACHE II score ≥ 15 and men with reduced left ventricular ejection fraction after 2 months had a greater risk of poor prognosis. CONCLUSION: SCMP was more common in female patients. Female patients more commonly experienced preceding emotional stress, whereas physical stress was more common in male patients. Systolic dysfunction was more severe in men. Long-term clinical outcomes appeared to be similar between men and women.

BACKGROUND AND OBJECTIVES: For the development of an arteriogenic gene therapy in peripheral artery occlusive disease, we developed a novel angiogenesis assay, with electroporation-mediated naked DNA delivery to the skeletal muscle. MATERIALS AND METHODS: The levels of the expression CAT were compared between pJDK and pcDNA3.1, in HeLa and C2C12 cell lines, and skeletal muscle. The well known angiogenic gene, pJDK-hVEGF165, was injected, intramuscularly, into the tibialis anterior muscle of Balb/C mice, which was followed by electroporation. Two days later, the anterior tibialis muscles were divided into halves, embedded, and cultured in growth factor-reduced Matrigel. The capillary network area formed by the newly sprouting tube-like structures was calculated. For validation of this ex vivo assay, the connective tissue growth factor gene (pJDK-CTGF) was tested both by this new assay, and by the mice-hind limb ischemia model, with Laser Doppler imaging. RESULTS: The pJDK showed a significantly higher level of CAT expression than the pcDNA3.1. From the pJDK-hVEGF165 injected explants, endothelial cell migration and tube-like formation occurred on day 2, and the capillary network formation peaked on day 7. The capillary network formation in the pJDK-hVEGF165 group was markedly increased to that in the pJDK group. From the skeletal muscle assay, the pJDK-CTGF showed no angiogenic activity or attenuated VEGF-induced capillary network formation. The LDI flux ratio, on day 10 in the mice-hind limb ischemia model, for the mice treated with the pJDK-CTGF and pJDK-hVEGF165 was significantly lower than that of the mice treated with the pJDK-hVEGF165 alone. CONCLUSION: The skeletal muscle ex vivo assay, using an electroporation-mediated naked DNA delivery, is a simple, quantitative and reproducible method for assessing angiogenic genes. CTGF could be an anti-angiogenic factor due to its inhibition of VEGF.

PURPOSE: Icodextrin in peritoneal cavity is absorbed via the lymphatics to the blood and metabolized to maltose and maltriose which may interfere with correct measurement of glucose. In an attempt to evaluate the effects of icodextrin on the erroneous results of blood glucose, we measured blood glucose by different methods. METHODS: Peripheral capillary blood and venous blood were obtained from 12 patients using icodextrin and from 12 patients not using icodextrin. Venous blood glucose was measured by using the laboratory technique (glucose oxidase method), and capillary blood glucose was measured by using a Surestep (glucose oxidase method) and an Acucheck (GDH-PQQ method). To estimate icodextrin and its metabolites indirectly, we calculated osmolal gap. We measured blood icodextrin and its metabolites with amyloglucosidase in icodextrin group. RESULTS: In icodextrin group, glucose was overestimated in the results of the GDH-PQQ method (delta= GDH-GOD=56.2+/-30 mg/dL [vein] 58+/-32 mg/dL [capillary]), but in the control group, there were no significant differences in the results between the glucose oxidase method and the GDH-PQQ method. There was a correlation between the osmolal gap and the differences in the results (delta=GDH-GOD) (r=0.741, p=.006 [vein], r=0.671, p=.017 [capillary]). Blood icodextrin and its metabolites were related with the differences in the results (delta=GDH-GOD) (p=.026, r=0.635), but there was no significant correlation between the osmolal gap and the icodextrin and its metabolites (p=0.086, r=0.515). CONCLUSION: Icodextrin and its metabolites may lead to erroneously high blood glucose levels when measured by GDH-PQQ method. It is necessary to be aware of this factor in order to prevent overlooking dangerous hypoglycemia.
