The aim of this report was to study the oculomotor nerve and the abducens nerve in 2 such p atients with magnetic resonance imaging. Design: Observational case reports. Met hods: Ophthalmologic examination and thin-sectioned magnetic resonance imaging across the brainstem level were performed in 2 patients with CFEOM and synergist ic divergence. To confirm the accuracy of the procedure, we compared the results obtained with those of a control group of 40 individuals using the same techniq ue. Main Outcome Measures: The oculomotor nerve and the abducens nerve on magnet ic resonance imaging. Results: Magnetic resonance imaging disclosed bilateral hy poplasia of the oculomotor nerve in both patients, and absence of the abducens n erve on the affected side of synergistic divergence. The oculomotor and abducens nerves were observed in 80 of 80 eyes (100%) screened as controls. C onclusions: In both patients with CFEOM and synergistic divergence, the oculomot or nerve was hypoplastic bilaterally, and the abducens nerve was absent on the s ide exhibiting synergistic divergence.展开更多

Neither upper nor lower gastrointestinal (GI) endoscopy showed any localized lesions. Thus, the source of his GI bleeding was suspected to be in the small intestine, and he underwent peroral double-balloon enteroscopy (DBE) using EN-450T5 (Fujinon-Toshiba ES System Co., Tokyo, Japan). There were no lesions considered to be the source of GI bleeding. After the procedure, the patient began to experience abdominal pain. Laboratory tests revealed hyperamylasemia and abdominal computed tomography revealed an inflammation of the pancreas and the peripancreas. He was thus diagnosed to have acute pancreatitis. Conservative treatments resulted in both clinical and laboratory amelioration. He had no history of alcohol ingestion, gallstone disease or pancreatitis. Magnetic resonance cholangiopancreatography demonstrated no structural alterations and no stones in the pancreatobiliary ductal system. As his abdominal pain started after the procedure, his acute pancreatitis was thus thought to have been related to the peroral DBE. This is the first reported case of acute pancreatitis probably associated with peroral DBE.展开更多

The pathophysiology of IBD is probably the result of the complex interaction of genetic susceptibility and environmental influences. There is a well-known risk of thrombosis in patients with IBD. We present the case of a 53-year-old man with ulcerative colitis, who spontaneously developed intracranial sinus thrombosis that was treated with low molecular weight heparin. Literature was searched to assess the frequency and characteristics of cerebral sinus thrombosis in IBD and the role of certain etiopathological factors in such thrombotic patients.展开更多

We base our analysis on S&P 500 Composite Index constituents for the period of 2006-2012. Data were collected from Thomson Reuteurs, Compustat and Demerjian, Lev, and McVay (2012). We find that forecast accuracy is positively associated with managerial ability in the case of sales forecasts. Specifically, more able managers are associated with lower magnitude's forecast errors in the case of sales forecasts. Additional analysis finds that managerial ability is immaterial to EPS figures' forecast accuracy, i.e., EPS forecasts appear not to be affected by manager's superiority. Regarding sales forecasts, the results are consistent with the assertion that managers impact the quality of the delivered management forecasts. Regarding EPS forecasts, the results are in alignment with Demerjian, Lev, Lewis, and McVay (2013) who highlighted that managerial ability is an ability score related to the entire management team.展开更多

Affected by many factors, such as investment limits, inflation and interest rate cut, the rate of return on investment is very low. The introduction of the new policy allows the basic pension fund to enter the capital market, which is of great significance to improve the rate of return on investment, ease the pressure of capital gap, and promote the healthy development of the capital market. This paper makes a deep analysis of the rationality of the basic endowment insurance fund entering the market, and then puts forward some suggestions to avoid the risk of the pension market.展开更多

The advanced prediction of them has become a hotspot. Based on analysis of physical characteristics of the disaster sources and comparative evaluation of accuracy of the main advanced geophysical detection methods, we proposed a comprehen- sive judging criterion that tectonic interface can be judged by the elastic wave energy anomaly, strata water abundance can be discriminated by apparent resistivity response difference and establish a reason- able advanced prediction system. The results show that the concealed disaster sources are detected effec- tively with the accuracy rate of 80% if we use advanced prediction methods of integrated geophysics combined with correction of seismic and electromagnetic parameters, moreover, applying geological data, we may then distinguish types of the disaster sources and fulfill the qualitative forecast. Therefore, the advanced prediction system pays an important referential and instructive role in laneway driving project.展开更多

However, metastasis to the spleen from adrenal pheochromocytoma is extremely rare and has not been reported in literature. This report presents a case of a 58 year-old male patient who developed spleen-only metastases in July 2007. The patient had a previous history of left epinephroectomy for adrenal pheochromocytoma in January 2003. Abdominal computed tomography demonstrated multiple enhancing lesions suggestive of metastases; thus splenectomy was performed. Pathological examinations confirmed the diagnosis of splenic metastases from pheochromocytoma. The patient was alive without recurrence 48 months after splenectomy. qttis study is the first report on splenic metastasis from previous adrenal pheochromocytoma, and long-term survival was achieved by splenectomy. A history of malignancy indicates a high index of suspicion for splenic metastasis, and long-term survival can be achieved by splenectomy for spleen-only metastasis.展开更多

This extremely rare type of tumor occurs most commonly in superficial locations. The case we describe herein is that of a 60- year-old man with two large hepatic masses. The patient's tumor was removed radically through an incision due to the inconclusive imaging findings. Follow-up computed tomography showed no recurrence and metastasis after 37 months, suggesting that enucleation was adequate for tumor eradication. To our knowl-edge, this is the first reported case of low-grade myofibroblastic sarcoma in the liver in the English language literature.展开更多

However, evidence that p RT influences prostate-specific antigen response in patients with CRPC on systemic therapy is lacking. We describe three cases of CRPC progressing after treatment with docetaxel(n=2) and abiraterone(n=1), who responded unusually after p RT for bone pain with the development of a significant biochemical response and restoration of response to systemic therapy. The possibility of p RT influencing metastatic disease in CRPC has not been previously reported, and raises the possibility of radiation-induced modulation of anti-tumor immune response mechanisms that may play a role in the restoration of response to systemic treatment.展开更多

The quality level of this accounting information comes from the company's governance practices, thereby emphasizing the importance of corporate governance in companies. Recently, following the financial crises resulting in accounting scandals, attention has been moving towards internal audit function as an important factor in the structure of corporate governance. This paper therefore examined the extent of the relationship between internal audit function and the quality of accounting information of companies. The study adopted the survey research design. The research instrument employed was questionnaire which was administered to internal auditors of the "Big Four". Linear regression analysis was employed in the analysis of the data collected with the use of Statistical Packages for Social Sciences (SPSS). The results revealed that there is a significant relationship between the internal audit characteristics and the quality of accounting information. It was recommended that in order to provide credibility to the financial statement, there should be a law in place mandating attachment of internal auditors report to the financial statement.展开更多

Most of patients are asymptomatic; a few patients have mild jaundice or abdominal discomfort. To our knowledge, there were only a few cases of biliary papillomatosis reported in the previous literatures, which only showed solitary tumor in bile duct. We presented a rare case with multiple biliary adenomas in extrahepatic bile duct confirmed by endoscopic retrograde cholangiopancreatography(ERCP) and histopathology. After 3 months follow-up, the patient remained asymptomatic.展开更多

The predictability limit, obtained from the evolutions of nonlinear error entropy and climatological state entropy, is not only used to measure the predictability of dynamical system with the constant climatological state entropy, but also appropriate to the case of climatological state entropy changed with time. With the help of daily NCEP-NCAR reanalysis data, by using a method of local dynamical analog, the nonlinear error entropy, climatological state entropy, and predictability limit are obtained, and the SVPLs and MJPL of the winter 500-hPa temperature field, zonal wind field and meridional wind field are also investigated. The results show that atmospheric predictability is well associated with the analytical variable. For single variable predictability, there exists a big difference for the three variables, with the higher predictability found for the temperature field and zonal wind field and the lower predictability for the meridional wind field. As seen from their spatial distributions, the SVPLs of the three variables appear to have a property of zonal distribution, especially for the meridional wind field, which has three zonal belts with low predictability and four zonal belts with high predictability. For multivariable joint predictability, the MJPL of multivariable system with the three variables is not a simple mean or linear combination of its SVPLs. It presents an obvious regional difference characteristic. Different regions have different results. In some regions, the MJPL is among its SVPLs. However, in other regions, the MJPL is less than its all SVPLs.展开更多
