introduction: this study evaluates the accuracy of renal ultrasonography (us) in the detection of vesicoureteral reflux (vur) compared to voiding cystourethrography (vcug). methods: we retrospectively reviewed the medical records of 131 children with urinary tract infection. ultrasound findings were considered to be suggestive of vur if a “pelvocalyceal dilatation”‚ “retrovesical ureteral dilat...

Introduction: Renal Ischemia Reperfusion is considered to be one of the causes of acute renal failure (AKI). In addition, renal ischemia is an important incident usually occurs due to renal transplantion, repair of suprarenal aneurysm, hemorrhagic shock. A recent study reported that reactive oxygen species (ROS) are important mediators of AKI. It seems essential to use antioxidant to decrease t...

AIMS Glimepiride is a new sulfonylurea for diabetes treatment which is supposed to impact less on extra-pancreatic ATP-dependent K+ channels than the conventional drug glibenclamide. This study was performed to evaluate whether this results in a better maintenance of ATP-dependent K+ channel mediated ischaemic myocardial preconditioning. METHODS AND RESULTS In a double-blind placebo-controlle...

Typical patients with MVP, especially global leaflet prolapse or Barlow type prolapse, have prominent MV annular dilatation with only modest LV dilatation. This discrepancy suggests that patients with MVP and annular dilatation frequently have basal predominance of LV dilatation (Figure 1). Predominantly, basal LV dilatation may cause greater systolic wall tension in the LV base compared with t...

background:  the aim of the study was to compare the radioprotective efficacy in the kidney of l-carnitine to that of amifostine. materials and methods: thirty three-month-old wistar albino rats were randomly assigned to four groups: group 1 (control); group 2 (irradiation alone); group 3 (amifostine plus irradiation); and group 4 (l-carnitine before irradiation). the rats in groups 2, 3, and 4...

AIM To evaluate the safety and efficacy of upper esophageal sphincter (UES) dilatation for cricopharyngeal (CP) dysfunction. To determine if: (1) indication for dilatation; or (2) technique of dilatation correlated with symptom improvement. METHODS All balloon dilatations performed at our institution from over a 3-year period were retrospectively analyzed for demographics, indication and dila...
