Background and Aim: Recurrent aphthous stomatitis (RAS) is one of the most common lesions in the oral mucosa. The etiopathogenesis of RAS is not clear. RAS is multifactorial, and several factors can contribute to RAS development. This study aimed to evaluate the RAS prevalence and some related factors in 12-17-year-old schoolchildren in Zahedan City (Southeast of Iran). Materials and Methods: ...

renal artery stenosis (ras) is the most common cause of secondary hypertension. preliminary data indicate that aspirin renography with hippurate may be more sensitive for detection ras. in this study 20 patients with known or suspected ras underwent aspirin renography (20 mg/kg orally 1 hour before injection of radiotracer) and captopril renography (50 mg orally) with 99mtc-dtpa. renal angiogra...
