Background and Objectives: The prognostic implications of septic cardiomyopathy have not been clearly demonstrated. We evaluated serial changes in left ventricular (LV) and right ventricular (RV) function in patients with septic shock and their prognostic value on 7-day and in-hospital mortality. Methods: Transthoracic echocardiography was performed within 48 hours of the diagnosis of septic shock and 7 days after the initial evaluation. In addition to traditional echocardiographic parameters, LV and RV function was evaluated using global longitudinal strain (GLS), and tricuspid annular plane systolic excursion (TAPSE). Results: A total of 162 patients (men, 83, 51.5%; 70.7±13.4 years; Acute Physiology and Chronic Health Evaluation [APACHE] II, 30.6±9.2) were enrolled. Initial GLS and TAPSE were -14.9±5.2% and 16.9±5.5 mm, and improved in the follow-up evaluation (GLS, -17.6±4.9%; TAPSE, 19.2±5.4 mm). Seven-day and in-hospital mortality were 24 (14.9%) and 64 (39.8%). Seven-day mortality was significantly associated with initial GLS >-16% (odds ratio [OR], 14.066, 95% confidence interval [CI], 1.178-167.969, p=0.037) and APACHE II score (OR, 1.196, 95% CI, 1.047-1.365, p=0.008). The in-hospital mortality of 7-day survivors was associated with follow-up TAPSE <16 mm (OR, 10.109, 95% CI, 1.640-62.322, p=0.013) and Sequential Organ Failure Assessment score (OR, 1.340, 95% CI, 1.078-1.667, p=0.008). GLS was not associated with in-hospital mortality of 7-day survivors. Conclusions: Fluctuation of both ventricular function was common in septic shock. Seven-day mortality of patients with septic shock was related to GLS, whereas in-hospital mortality of 7-day survivors was related to TAPSE, not to GLS.

Background: Brain metastases occur in about 20-40% of patients with non-small-cell lung carcinoma (NSCLC), and are usually associated with a poor outcome. Whole brain radiotherapy (WBRT) is widely used but increasingly, more aggressive local treatments such as surgery or stereotactic radiosurgery (SRS) or stereotactic radiotherapy (SRT) are being employed. In our study we aimed to describe the various factors affecting outcomes in NSCLC patients receiving local therapy for brain metastases. Materials and Methods: The case records of 125 patients with NSCLC and brain metastases consecutively treated with radiotherapy at two tertiary centres from January 2006 to June 2012 were analysed for patient, tumour and treatment-related prognostic factors. Patients receiving SRS/SRT were treated using Cyberknife. Variables were examined in univariate and multivariate testing. Results: Overall median survival was 3.4 months (95%CI: 1.7-5.1). Median survival for patients with multiple metastases receiving WBRT was 1.5 months, 1-3 metastases receiving WBRT was 3.6 months and 1-3 metastases receiving surgery or SRS/SRT was 8.9 months. ECOG score (${\leq}2$ vs >2, p=0.001), presence of seizure (yes versus no, p=0.031), treatment modality according to number of brain metastases (1-3 metastases+surgery or $SRS/SRT{\pm}WBRT$ vs 1-3 metastases+WBRT only vs multiple metastases+WBRT only, p=0.007) and the use of post-therapy systemic treatment (yes versus no, p=0.001) emerged as significant on univariate analysis. All four factors remained statistically significant on multivariate analysis. Conclusions: ECOG ${\leq}2$, presence of seizures, oligometastatic disease treated with aggressive local therapy (surgery or SRS/SRT) and the use of post-therapy systemic treatment are favourable prognostic factors in NSCLC patients with brain metastases.

Purpose: We analyzed the oncological outcome and prognostic factor of the chondrosarcoma arising from benign bone tumor due to malignant transformation. Materials and Methods: From April 1986 to April 2009, 18 cases were considered eligible. We analyzed retrospectively the patient's characteristics and prognostic factors that affect to the local recurrence and distant metastasis. Results: As classified by primary benign bone tumor, 4 cases were solitary osteochondroma, 11 cases were multiple osteochondromatosis and 3 cases were multiple enchondromatosis. The mean follow-up period was 85 months. The 5-year disease free survival rate of 18 patients was 85.9%. Their overall MSTS score was 25.2 (84%). There were local recurrence in 3 cases and no distant metastasis. We found that tumor location and surgical margin affected to the prognosis significantly. Conclusion: In secondary chondrosarcoma patients, the prognosis was good relatively and tumor location and surgical margin are important prognosis factor.

Background: Previous reports have shown that human epidermal receptor (HER)-3 overexpression may be associated with poor prognosis in patients with breast cancer, but results have been conflicting. In this study, we sought to investigate the prognostic significance of HER-3 immunohistochemical expression in patients with metastatic breast cancer. Methods: We retrospectively analyzed HER-3 immunohistochemical expression profiles in 45 paraffin-embedded specimens from patients who had been treated between 1996 and 2006 in the Department of Oncology of the Uludag University School of Medicine, Bursa, Turkey. Membranous or cytoplasmic dominant expression patterns of HER-3 were analyzed using the Rajkumar score and a cytoplasmic 4-point scoring system, respectively. Progression-free survival (PFS) and overall survival (OS) served as the main outcome measures. Results: The median PFS in the study participants was 9 months (interquartile range: 4.5-13 months), whereas the median OS was 20 months (interquartile range: 7.5-28 months). Categorization of the patient population according to HER-3 positive immunohistochemical expression did not reveal any statistically significant difference in terms of both PFS (p=0.70) and OS (p=0.81). The results of multivariable Cox regression analysis indicated that tumor size was the only independent predictor of PFS, whereas estrogen and progesterone receptor status was independently associated with OS. Conclusions: HER-3 immunohistochemical expression did not correlate with outcomes in Turkish patients with metastatic breast cancer. Although our results suggest that HER-3 expression in cancer specimens is not of prognostic significance, further prospective studies are warranted to confirm these results.

Objectives: The purpose of this study was to evaluate for prognostic significance of VEGF expression and tumor angiogenesis in papillary carcinomas of the thyroid. Materials and Methods: The materials were 79 cases of papillary thyroid carcinomas, and age, sex, tumor size, multiplicity of tumor, capsular invasion, lymph node metastasis, recurrence, TNM stage, DeGroot stage and AMES scale were evaluated. An immunohistochemical stains for CD 34 to estimate microvessel density (MVD), and VEGF were done. MVD was defined as an average count of vessels per ${\times}400$ power field in the most vascularized area. VEGF expression was interpreted as 1+ and 2+ according to staining intensity and percentages of positive cells. Results: Mean score of MVD was $39.7{\pm}16.9.$ MVD were significantly higher in cases with capsular invasion (p=0.0001), lymph node metastasis (p=0.0001), TNM stage III (p=0.0022), DeGroot stage III (p=0.0163) and high risk group by AMES scale (p=0.0001). VEGF 2+ expression rate was significantly increased in cases with capsular invasion and lymph node metastasis (p=0.0006, p=0.0013), and in cases with TNM stage III, DeGroot stage III and high risk group by AMES scale (p=0.0236, p=0.0003, p=0.0293). In VEGF 2 + expression group, MVD was significantly higher than in VEGF 1 + group (p=0.0008), and MVD showed positive relation to VEGF 2 + expression (r=0.4616). Conclusion: VEGF expression and high MVD were significantly correlated to capsular invasion, lymph node metastasis, TNM stage III, DeGroot stage III and high risk group by AMES scale. The expression of VEGF and high MVD could be considered to be one of prognostic factor in papillary thyroid carcinomas.

Background: Traumatic diaphragmatic rupture is not common, but it requires swiftly performing an emergency operation. This study was conducted to evaluate the prognostic factors for mortality after surgically treating traumatic diaphragmatic rupture. Material and Method: From Jan 2001 to Dec. 2008, we experienced 37 cases of multiple traumas with diaphragmatic injuries that were confirmed by surgical procedures. We evaluated various factors, including the type of injury, the associated injuries, the preoperative vital signs, the ISS, the time until surgery and the rupture size. Result: There were 30 patients with blunt trauma and 7 patients with penetrating trauma. Thirty-four patients had associated injuries and the mean ISS was 20.8. Postoperative complications occurred in 11 patients and hospital mortalities occurred in 6 patients. The prognostic factors that had an influence on the postoperative mortalities were the preoperative intubation state, the patient who exhibited hypotension and a high ISS. Conclusion: Traumatic diaphragmatic rupture is just one part of multiple traumas. The postoperative mortalities might depend on not only on the diaphragmatic rupture itself, but also on the severity of the associated injuries.

Purpose: We wanted to assess the radiological and clinical results and the prognostic factors after an operation for capitellar fractures associated with/without other injury around the elbow. Materials and Methods: Among the 25 patients (mean age: 49 years-old) who underwent open reduction and internal fixation for capitellar fractures, there were nineteen type 1 fractures and six type 3 fractures. The mean follow up period was 14.8 months. We assessed the factors affecting the radiological and functional results, such as the fracture pattern, the patient age and the surgical approaches. Results: In 24 of 25 patients, bony union was achieved at postoperative 1 year. There were eighteen excellent, four good, two fair and one poor functional results according to the Broberg and Morrey elbow score. The most common type was type 1 and the most common associated injury was lateral condylar fracture. The patients with type 1 fracture rather than the patients with type 3 fracture and the patients who had an extraarticular associated fracture rather than an intraarticular associated fracture had better clinical outcomes. Conclusion: 22 (88%) of the patients were satisfied at the result. The type of capitellar fracture and an associated intraarticular elbow fracture were shown to be important prognostic factors in this study.

Background : The plasma B-type natriuretic peptide(BNP) concentration increases with the degree of pulmonary hypertension in patients with chronic respiratory disease. The aim of this study was to examine the prognostic role of BNP in the acute exacerbation of chronic obstructive lung disease (COPD). Method : We selected 67 patients who were admitted our hospital because of an acute exacerbation of COPD. Their BNP levels were checked on admission at the Emergency Department. Their medical records were analyzed retrospectively. The patients were divided into two groups according to their in-hospital mortality. The patients' medical history, comobidity, exacerbation type, blood gas analysis, pulmonary function, APACHE II severity score and plasma BNP level were compared. Results : Multiple logistic regression analysis identified three independent predictors of mortality: $FEV_1$, APACHE II score and plasma BNP level. The decedents group showed a lower $FEV_1$($28{\pm}7$ vs. $37{\pm}15%$, p=0.005), a higher APACHE II score($22.4{\pm}6.1$ vs. $15.8{\pm}4.7$, p=0.000) and a higher BNP level ($201{\pm}116$ vs. $77{\pm}80pg/mL$, p=0.000) than the sSurvivors group. When the BNP cut-off level was set to 88pg/mL using the receiver operating characteristic curve, the sensitivity was 90% and the specificity was 75% in differentiating between the survivors and decedents. On Fisher's exact test, the odds ratio for mortality was 21.2 (95% CI 2.49 to 180.4) in the patients with a BNP level > 88pg/mL. Conclusion : The plasma BNP level might be a predictor of mortality in an acute exacerbation of COPD as well as the $FEV_1$ and APACHE II score.

GenesWell$^{TM}$ BCT is a 12-gene test suggesting the prognostic risk score (BCT Score) for distant metastasis within the first 10 years in early breast cancer patients with hormone receptor-positive, HER2-negative, and pN0~1 tumors. In this study, we validated the analytical performance of GenesWell$^{TM}$ BCT. Gene expression values were measured by a one-step, real-time qPCR, using RNA extracted from FFPE specimens of early breast cancer patients. Limit of Blank, Limit of Detection, and dynamic range for each of the 12 genes were assessed by serially diluted RNA pools. The analytical precision and specificity were evaluated by three different RNA samples representing low risk group, high risk group, and near-cutoff group in accordance with their BCT Scores. GenesWell$^{TM}$ BCT could detect gene expression of each of the 12 genes from less than $1ng/{\mu}L$ of RNA. Repeatability and reproducibility across multiple testing sites resulted in 100% and 98.3% consistencies of risk classification, respectively. Moreover, it was confirmed that the potential interference substances does not affect the risk classification of the test. The findings demonstrate that GenesWell$^{TM}$ BCT have high analytical performance with over 95% consistency for risk classification.

Nowadays there were two tendencies of studies about prognostic factors in stroke. One way was to define prognostic factors according to the radiological features. And the other way was to define according to the mental state, recognition, perception, motors, language, urinary&bowel incontinence etc.. The former could be objectively investigated, while the latter was difficult. The purpose of this study was to determine which variables would be predictors of stroke and which factors would be affect predictions most. The subjects of this study were 32 patients who were admitted to the Dept. of Internal Medicine, Dongguk Univ. College of Oriental Medicine whthin 48 hours from attack, Medical records were reviewed FIM, CNS, NIH stroke scale. We compared each sub-items of FIM, CNS, NIH stroke scale about mental state, recognition, perception, motors, language, urinary&bowel incontinence with MBI score at 4 weeks from admission. Also, we analyzed the correlations of sub-items and groups which devided into 5 according to independence of MBI score. And we found out the most influent factors with multiple regression analysis. The major results were as follows; 1. In mean of MBI score at 4 weeks of each groups devided low, middle, high score at mental state, recognition, perception, motors, language, urinary&bowel incontinence items, there were statistical differences in all items. 2. The mental state and lim ataxia sub-items had no significant correlations with groups divided according to independence of MBI score. All the other items were significantly correlated. 3. The most influent factors was recognition. The second was sensory and the third was bowel incontinence. 4. The most influent scales was FIM, and the second was CNS, and NlH had no statistical significancy.
