Introduction: Ureteropelvic junction obstruction (UPJO) is associated with inadequate urine drainage from renal pelvis into ureter. UPJO results from incomplete recanalization of proximal ureter during fetal period which finally leads to hydrostatic distention of renal pelvis and calyces. Diagnosis is based on clinical symptoms, ultrasound, and diuretic isotopic renogram. Various surgical metho...

Introduction: Paediatric patients deserve special attention because of the higher radiation risks compared with adults. The main purpose of this study is to determine patient dose and diagnostic reference level for Paediatric through Entrance Surface Dose (ESD) calculations in common X-ray examination and to establish Paediatric national DRLs in digital radiography in Iran. <...

conclusions although the data support the idea that the basic mechanism of imipenem resistance could be via the loss of oprd, they do not fully explain the role of oprd and indicate that other mechanisms may play an important role. additionally, the significant decrease in the oprd levels in mdr strains suggests that oprd also plays a role in the emergence of both carbapenem and non-carbapenem ...

conclusions ap did not prevent utis and resulted in more resistant organisms requiring iv antibiotics. discontinuing ap allowed the return of susceptibility to oral antimicrobials and significantly improved gfr in those children who had previously been on ap. adherence to a catheterization regimen with prompt treatment of symptomatic uti conserved renal function and prevented selection of resis...

Introdouction: The high prevalence of apical periodontitis (AP) of endodontic origin raises an important public health problem. Root canal treatment (RCT) and crown restoration (CR) have an effect on its prevalence. This cross-sectional study was performed to assess the effect of RCT and CR on the prevalence of AP. Materials and methods: Two observers assessed 608 teeth with RCT belonging to p...

Introduction: Medical uses of radiation have grown very rapidly over in the past two decades, medical uses represent the largest source of exposure to people, The most important methods in medical diagnosis are the useses of diagnostic radiology exams. Although the use of these methods is very beneficial for the treatment of patients, but ionizing radiation produces ion pairs, ...

background: accumulating evidence indicates that inflammatory cells migrate into the pancreas tissue and play an important role in the pathogenesis of acute pancreatitis (ap). the aim of this study was to establish a flow cytometric method to enumerate these infiltrating cells in the pancreas of an experimental ap. materials and methods: twelve hours after inducing of ap, mice pancreatic tissue...

purpose : to determine add power (ap) and amplitude of accommodation (aa) in a sample of iranian population and its relationship with refractive errors methods : this cross-sectional study enrolled people of 35-70 years old by simple random sampling. exclusion criteria were myopia or hyperopia over 6 diopter (d) and astigmatism more than 0.75 d. those with a history of eye disorders and taking ...
