We performed this study to investigate the possible association between vitamin D receptor (VDR) gene polymorphism and the focal bone erosion in rheumatoid arthritis (RA) patients in Korea. One hundred and fifty-seven RA patients were enrolled and two control groups were selected. The focal bone erosion score was assessed by modified Sharp's method.(More)
OBJECTIVES Spontaneous intracranial hypotension (SIH) is caused by spontaneous spinal cerebrospinal fluid (CSF) leaks. However, there is debate regarding clinical indication of radionuclide cisternography (RNC) for identification of the actual site of a CSF leak. We therefore investigated the potential value of RNC in SIH. PATIENTS AND METHODS RNC was(More)
Oxidative stress, and in particular oxidation of lipoproteins, is a hallmark of atherosclerosis. Upon entry of lipoproteins into the vessel wall, a cascade of pro-atherogenic pathways is initiated whereby the reaction of reactive oxygen species with substrates amenable to oxidation, such as polyunsaturated fatty acids, generates a variety of(More)
Retroperitoneal fibrosis is a rare disease characterized by the formation of dense plaque of fibrous tissue covering the retroperitoneal structures. This disease is commonly presented as ureteral obstruction, but the involvement of duodenum is rare. We report a case of retroperitoneal fibrosis which was complicated with duodenal stenosis and was(More)
The thromboembolic complications of nephrotic syndrome are reasonably common, including spontaneous peripheral venous and/or arterial, pulmonary arterial, and renal venous occlusions. However, in comparison to the relatively high incidence of the venous thromboembolic complications with hypercoagulable status, arterial thromboses have been reported much(More)
PURPOSE Vascular endothelial growth factor (VEGF) levels in malignant ascites have high diagnostic value for their discrimination from ascites of non-malignant origin. However, there have been no reports on the comparison of VEGF levels between malignant ascites of chemonaive and chemotreated patients. MATERIALS AND METHODS VEGF levels were measured in 44(More)
Identification of tumor imaging features associated with metastatic pattern may allow better understanding of cancer dissemination. Here, we investigated how primary tumor F-fluorodeoxyglucose (FDG) avidity influences the first site of breast cancer metastasis.Subjects were 264 patients with advanced breast cancer who underwent positron emission(More)
To fully understand the glycolytic behavior of cancer cells, it is important to recognize how it is linked to pH dynamics. Here, we evaluated the acute effects of mild acidification and alkalization on cancer cell glucose uptake and glycolytic flux and investigated the role of hexokinase (HK). Cancer cells exposed to buffers with graded pH were measured for(More)
We present a case of primary benign intraosseous meningioma in the sphenoid bone mimicking malignancy. A 44-year-old female patient who had a protruding right eye and headache came to our hospital. MRI showed a large, destructive, heterogeneously well-enhancing soft tissue mass in the right sphenoid bone suggesting malignancy. (18)F-FDG PET/CT showed a(More)
