PURPOSE: To assess the value of positional shifting to a gravity-dependent area, as revealed by HRCT, in differ-entiating pulmonary edema (PE) from other conditions. MATERIALS AND METHODS: Sixteen consecutive patients in whom plain radiographs suggested the presence of pulmonary edema but the clinical findings were indefinite underwent HRCT of the lung. For initial scanning they were in the supine position, and then in the prone position. Findings of ground-glass opacity, interlobular septal thickening and peribronchovascular interstitial thickening were analyzed in terms of the presence and degree of shifting to a gravity-dependent area, a grade of high, intermediate or low being assigned. RESULTS: PE was diagnosed in 8 of 16 cases, the remainder being designated as non-pulmonary edema (NPE). Ground-glass opacity was observed in all 16, while the degree of positional shifting was found to be high in ten (PE:NPE=6:4), intermediate in four (PE:NPE=2:2), and low in two (PE:NPE=0:2). There was no significant difference between the two groups (p > 0.05). Interlobular septal thickening was observed in all but two NPE cases; the degree of shifting was high in six (PE:NPE=6:0), intermediate in one (PE), and low in seven (PE:NPE=1:6). Shifting was significantly more prominent in PE than in NPE cases (p<0.05). Peribronchovas-cular interstitial thickening was positive in all PE cases and one NPE case, with no positional shifting. CONCLUSION: Positional shifting of interlobular septal thickening to a gravity-dependent area, as demonstrated by HRCT, is the most specific indicator of pulmonary edema.

BACKGROUND & METHODS: Approximately 10% of the essential hypertensive patient have overt proteinuria due to renal target organ damage, which indicates poor prognosis. Recently microalbuminuria has been prove to be a good early predictor for renal damage in patients with diabetes or hypertension. Some authors reported that near 40% of the essential hypertensives have microalbuminuria. To determinate prevalence of microalbuminuria in Korea essential hypertensives, 24-hr ambulatory blood pressure monitoring and radioimmunoassay to detect BP and UAER were performed after 4 weeks wash-out period in 137(78 hypertensive and 54 normotensive) consecutive cases. RESULTS: Among 78 hypertensives, overt proteinuria was seen in 8.97%(7/78). And prevalence of microalbuminuria were 29.4%(23/78) in hypertensives and 16.7%(9/54) in normotensives. Urine microalbumin excretion rate(UAER) was significantly correlated with mean arterial pressure(MAP) in total subjects(r=0.286, p=0.0012), but not in total hypertensives(r=0.135, p=NS) or in hypertensives with UAER(r=-0.098, p=NS).UAER of female hypertensives was increase than that of male hypertensives(13.17+/-16.28microg/min vs 22.87microg/min, p=0.027). CONCLUSION: Prevalence of microalbuminuria in Korean hypertensives was relatively lower then other reports. Overt proteinuria was noted in 8.97% of the hypertensives which is same prevalence as other countries. Moreover MAP was well correlated with UAER in total subjects. Further evaluation should be done to detect exact role of UAER in hypertensives as an early predictor for renal target organ damage.

> BACKGROUND: The accuracy of flow-related changes in aortic valve area (AVA) determined by the Gorlin formula or the continuity equation remains disputable. However, anatomic AVA can be determined by using by direct planimetry of transesophageal echocardiography (TEE). The purpose of this study was to assess the impact of changes in flow on AVA determined by TEE using direct planimetry. METHOD: Determination of AVA by TEE using direct planimetey was performed intraoperatively under three different hemodynamic conditions - pre-dobutamine (baseline) period, post-dobutamine period, post-CABG period - in 17 CABG patients and cardiac output (CO) with left ventricular ejection fraction (EF) were also determined by TEE simutaneously. The changes in aortic flow were induced by dobutamine infusion. RESULTS: AVA at pre-dobumaine period, post-dobutamine period, and post-CABG period were 2.99+/-0.80 cm2, 3.01+/-0.79 cm2, and 3.01+/-0.80 cm2, respectively. Before dobutamin infusion, CO and EF were 2.01+/-0.64 L/min and 47+/-10%. After dobutamine infusion, CO and EF were 3.03+/-1.05 L/min, 54+/-9% respectively and significantly increased by 54%, 18% than those measured before dobutamine infusion (p<0.01, p<0.01), respectively. After CABG, CO and EF were 3.86+/-1.86 L/min and 58+/-11% and also significantly increased by 98%, 26% than those measured before dobutamine infusion (p<0.01, p<0.01), respectively. However, despite of these significant hemodynamic changes, there were no significant changes in AVA and no significant correlations between these hemodynamic and AVA changes, neither at post-dobutamine period nor post-CABG period. CONCLUSION: The acute changes in CO and EF do not result in significant alterations in the anatomic AVA determined by TEE using direct planimetry. Thus, TEE using direct planimetry could be accurate and useful in the determination of AVA in hemodynamically unstable patient.

Osteoclasts (OCs) are clinically important cells that resorb bone matrix. Accelerated bone destruction by OCs is closely linked to the development of metabolic bone diseases. In this study, we screened novel chemical inhibitors targeting OC differentiation to identify drug candidates for metabolic bone diseases. We identified that 1,3-dibenzyl-5-fluorouracil, also named OCI-101, is a novel inhibitor of osteoclastogenesis. The formation of multinucleated OCs is reduced by treatment with OCI-101 in a dose-dependent manner. OCI-101 inhibited the expression of OC markers via downregulation of receptor activator of NF-κB ligand and M-CSF signaling pathways. Finally, we showed that OCI-101 prevents ovariectomy-induced bone loss by suppressing OC differentiation in mice. Hence, these results demonstrated that OCI-101 is a good drug candidate for treating metabolic bone diseases.

BACKGROUND: Depression is common in chronic renal failure patients and usually associated with poor appetite. Malnutrition with poor appetite is known to be associated with increased mortality in chronic hemodialysis (HD) patients. So we evaluated the prevalence, risk factors of depression and effects of depression to nutritional status in chronic HD patients. METHODS: Sixty two HD patients (age 48.8+/-11.1 years, diabetes 29%) were investigated. Each patients were interviewed and completed the Beck depression inventory (BDI, 21 items, 0-3 point). To exclude the possible confounding effects of illness and treatment symptoms, cognitive depression index (CDI, a cognitive subset of 15 items selected from BDI) was used as a measure of depression. KT/V and nutritional parameters such as serum albumin, normalized protein catabolic rate (nPCR), subjective global assesment (SGA), body mass index (BMI), triceps skinfold thickness (TSF) and midarm muscle circumference (MAMC) were also measured. RESULTS: Corrected BDI score (CDI score multiplied by 21/15) was 24.9+/-12.7 and the prevalence of depression (corrected BDI score > or = 21) was 64.5%. DM patients had higher CDI score than non DM patient (22.9+/-7.2 vs 15.6+/-9.0). In univariate analysis, CDI score was correlated with age (r=0.39, p<0.01), serum albumin (r=-0.37, p<0.005), nPCR (r=-0.30, p<0.05), SGA (r=-0.42, p<0.05), BMI (r=-0.28, p<0.05), TSF (r=-0.41, p<0.05) and MAMC (r=-0.50, p<0.01). In multivariate analysis, CDI score was the strongest correlate of nPCR, SGA, BMI, TSF and MAMC. But KT/V, hematocrit, erythropoietin usage, plasma bicarbonate, serum parathyroid hormone, c-reactive protein concentration and HD duration had no relationship with CDI score. CONCLUSION: The prevalence of depression in chronic HD patients was high. Diabetes and old agewere important risk factors for depression. It was also concluded that severity of depression was correlated with markers of malnutrition and depression could be a independent risk factor of malnutrition in chronic HD patients.

PURPOSE: To evaluate the radiographic and CT findings of pulmonary complications other than pulmonary edema arising from renal transplantation. MATERIALS AND METHODS: Among 393 patients who had undergone renal transplantation at our hospital during a previous ten-year period, 23 with pulmonary complications other than pulmonary edema were included in this study. The complications involved were infection caused by CMV (n=6), bacteria (n=4), fungus (n=4), tuberculosis (n=2), varicella (n=1) or chlamydia (n=1), and malignancy involving lung cancer (n=4) or Kaposi's sarcoma (n=1). Two chest radiologists reviewed all images. RESULTS: The complications manifesting mainly as pulmonary nodules were lung cancer(4/4), tuberculosis (1/2), and Kaposi's sarcoma(1/1). Pulmonary consolidation was a main feature in bacterial infection(4/4), fungal infection(3/4), tuberculosis(1/2), chlamydial infection(1/1), and varicellar pneumonia(1/1). Ground-glass attenuation was a main CT feature in CMV pneumonia(4/6), and increased interstitial marking was a predominant radiographic feature in CMV pneumonia(2/6). CONCLUSION: The main radiologic features described above can be helpful for differential diagnosis of the pulmonary complications of renal transplantation.

OBJECTIVE: Endometriosis is a common and recurring gynecologic disease which have afflicting females of reproductive age. We investigated the efficacy of long-term, post-operative use of dienogest for ovarian endometrioma. METHODS: We studied 203 patients who had undergone laparoscopic or robotic surgery for ovarian endometrioma, and were administrated dienogest 2 mg/day beginning in July of 2013, and continuing. We evaluated side effects of dienogest and ultrasonography was performed every 6 months to detect potential recurrence of endometrioma (2 cm) in these post-surgical patients. RESULTS: The follow-up observation periods were 30.2±20.9 months from surgery. The mean age was 34.1±7.2 years old. The mean diameter of pre-operative endometrioma was 5.6±3.0 cm2. One hundred eighty-two (89.7%) women received dienogest continuously for 12.0±7.1 months. Of the subjects, 21 (10.3%) patients discontinued dienogest at 2.4±1.0 months. The most common side effect when dienogest was discontinued was abnormal uterine bleeding. The occurrence rate of vaginal bleeding was 15.8%, a number which did not differ significantly in patients with/without post-operative gonadotropin releasing hormone agonist administration. The other side effects were gastrointestinal trouble including constipation, acne, headache, depression, hot flush, weight gain, and edema. However, no serious adverse events or side effects were documented and recurrent endometriomas were diagnosed in 3 patients (1.5%). CONCLUSION: The data indicates that dienogest was both tolerable and safe for long-term use as prophylaxis in an effort to obviate the recurrence of ovarian endometrioma post-operatively, as well as potential need for surgical re-intervention.

OBJECTIVE: Previous pathologic and roentgenographic studies have suggested a relation between aortic plaque and coronary artery disease but have lacked clinical utility. The study was undertaken to elucidate whether atherosclerotic aortic plaque detected by transesophageal echocardiography can be a clinically useful marker for significant obstructive coronary artery disease. METHODS: Clinical and angiographic features and intraoperative transesophageal echocardiographic findings were prospectively analyzed in 131 consecutive patients (58 women and 73 men, aged 17 to 75 years [mean 54 +/- 12]) undergoing open heart surgery. Significant obstructive coronary artery disease was defined as > or = 50% stenosis of > or = 1 major branch. RESULTS: Seventy-six (58%) of 131 patients were found to have obstructive coronary artery disease. In 76 patients with significant coronary artery disease, 71 had thoracic aortic plaque. In contrast, aortic plaque existed in only 10 of the remaining 55 patients with normal or minimally abnormal coronary arteries. The presence of aortic plaque on transesophageal echocardiographic studies had a sensitivity of 93%, a specificity of 82% and positive and negative predictive values of 88% and 90%, respectively, for significant coronary artery disease. There was a significant relationship between the degree of aortic intimal changes and the severity of coronary artery disease (r = 0.74, P < 0.0001). Multivariate logistic regression analysis of patient age, sex, risk factors of cardiovascular disease and transesophageal, echocardiographic findings revealed that atherosclerotic aortic plaque was the most significant independent predictor of coronary artery disease. CONCLUSION: This study indicates that transesophageal echocardiographic detection of atherosclerotic plaque in the thoracic aorta is useful in the noninvasive prediction of the presence and severity of coronary artery disease.
