BACKGROUND AND OBJECTIVES Endothelial dysfunction is an early manifestation of vascular injury and contributes to the development of atherosclerotic cardiovascular disease. Recent studies have implicated hyperuricemia as a risk factor for cardiovascular disease. We hypothesized that lowering uric acid in subjects with asymptomatic hyperuricemia with(More)
PURPOSE We present our 7-year experience with coaxial computed tomography (CT)-guided cutting needle lung biopsy and evaluate the factors affecting risk of complications. MATERIAL AND METHOD Between June 2000 and March 2007, we performed 225 CT-guided coaxial lung biopsies in 213 consecutive patients (161 men, 52 women). Lesion size, lesion depth, lesion(More)
BACKGROUND Currently the common pathogenetic mechanisms in nonalcoholic fatty liver disease (NAFLD) and obstructive sleep apnea (OSA) are gaining increased attention. The aim of this study is to find out the influence of chronic intermittent hypoxemia and OSA related parameters to the severity of NAFLD. METHODS We examined the liver functions tests and(More)
Treatment options of aneurysmal bone cysts include complete resection, curettage, curettage with bone grafting, selective arterial embolization (as a primary treatment or preoperative adjuvant therapy), and percutaneous injection of fibrosing agent. Treatment in pelvic locations is difficult because of the relative inaccessibility of the lesions, the(More)
Splenic artery aneurysm (SAA) is a well-known complication of chronic liver disease and portal hypertension in adults. The incidence of SAA in children undergoing selective hepatic angiography prior to liver transplantation is reported as 4%, but there are few systematic studies. To investigate the SAAs detected by multidetector CT angiography (MDCTA) among(More)
The interventional angiographic techniques using the percutaneous femoral approach for endovascular revascularization are becoming increasingly more popular. These methods usually require larger sheaths, and most patients need postprocedural anticoagulation or antiplatelet therapy. As a consequence, the interventional procedure is associated with a higher(More)
PURPOSE We aimed to determine the predictors of technical success and patency after percutaneous transluminal angioplasty (PTA) of de novo dysfunctional hemodialysis arteriovenous fistulas (AVF). METHODS We performed a retrospective analysis of first time PTA in 228 patients (129 men, 99 women; mean age, 56.8±14.6 years). Anatomical (location, length,(More)
Dysphagia is a common presenting complaint in otolaryngology practice, and there are many causes. Forestier syndrome is a rare cause of dysphagia. It is also known as diffuse idiopathic skeletal hyperostosis (DISH) syndrome or vertebral ankylosing hyperostosis. Forestier syndrome consists of anterolateral perivertebral ligament calcification. It was first(More)
Intramural renal pelvic and ureteral hemorrhage is seen most commonly in patients treated with anticoagulant therapy. However, spontaneous intramural hemorrhage of the ureter seen in patients with hemophilia is a rare entity and has been reported only in 2 cases. Computed tomography is a valuable imaging method in the diagnosis and follow-up. We report the(More)
Recently, the use of wireless body area networks (WBAN) has been increasing rapidly in medical healthcare applications. WBANs consist of smart nodes that can be used to sense and transmit vital data such as heart rate, temperature and ECG from a human body to a medical centre. WBANs depend on limited resources such as energy and bandwidth. In order to(More)
