Introduction: Relationship between periodontal infection and pulp pathosis has been debated for many years. This human case control study was performed to evaluate the possible effects of moderate to advanced chronic periodontitis on pulp stone formation and pulpal calcifications. Methods: Current study is an experimental case control study. Samples included 23 hopeless permanent teeth...
from sep. 1984 to aug. 1990,99 patients were treated for ureteral stone using the urekroscope. in five patients ureteroscopy was repeated for a second stone. in one patient the procedure was diagnostic in nature and in the rest of the patients it had a curative value. in 60 patients the stone was removed by electrohydraulic and basket combination and in25 cases, dilatation alone was enough. rat...
BACKGROUND The aim of the present study is to investigate the clinical relevance of aortic calcification in urolithiasis patients. METHODS Between January 2010 and September 2014, 1221 patients with urolithiasis were treated in Oyokyo Kidney Research Institute and Hirosaki University Hospital. Among these, 287 patients (Stone group) on whom adequate data were available were included in this r...
Background: Natural radioactivity in materials under certain conditions can reach the hazardous radiological levels. So, it becomes necessary to study the natural radioactivity in different materials to assess the dose for the population in order to know the health risks and to have a baseline for future changes in the environmental radioactivity due to human activities. Materials and ...
The prevalence of urinary tract stone disease is estimated to be 2-3%. There is not any absolute prophylactic and medical therapeutic measure for urinary stone disease. But there is significant improvement in minimally invasive surgical techniques for stone removal. PCNL (Percutaneous Nephro Lithotripsy) is a minimally invasive and safe technique to treat the urinary &...
Background: According to high prevalence of renal stone in children, we evaluated the efficacy of treatment with potassium citrate and its correlation with metabolic disorders in children less than two years of age with renal stone and microlithiasis. Methods: In this cross- sectionaly study, 100 patients (less than 2 years old) with renal stone or microlitiasis were evaluated for metabolic di...
liver functional tests due to inflammatory process which induced by cholecystitis might changed and some clinicians suggested that these changes might help us to stone prediction in common bile ducts and decrease hazards of performing ercp and other invasive procedures. present study was performed for assessment of role of liver functional test in diagnosis of common bile duct stone in patients...
This paper gives an overview of the OBST persistent object management system. OBST has been developed by the Forschungszentrum Informatik (FZI) as a contribution to the STONE project.1 The paper summarizes the design objectives and the current status of OBST, and highlights forthcoming developments with the system.
INTRODUCTION Urinary stone disease is a major urological condition. Endourologic techniques have influenced the clinical approach and outcomes. Open surgery holds a historic importance in the management of most conditions. However, complex kidney stone burden may be amenable to successful results with open stone surgery. In this article, we report our eighteen cases of complex urinary stone dis...
The collection of the rough set pairs of an approximation (U, R) can be made into a Stone algebra by defining two binary operators and one unary operator on the pairs. By introducing a more unary operator, one can get a regular double Stone algebra to describe the rough set pairs of an approximation space. Sequent calculi corresponding to the rough alg...
