OBJECTIVE To evaluate the role of vitamin A on renal scarring in recurrent urinary tract infections (UTIs). DESIGN Twenty three children with UTIs and renal scarring (mean (SD) age 7.3 (3.9) years) and 91 children without renal scarring (6.4 (3.4) years) were studied. All the children had serum vitamin A and beta-carotene measurements and nutritional evaluation. Renal scarring was assessed by...

Intrarenal splenosis is very rare and its management is not well established. We present a patient in whom an enhancing left renal mass was incidentally detected on a Computerized tomographic (CT) scan, concerning for renal cell carcinoma. However, the lesion was determined to represent intrarenal splenosis, confirmed by Technetium-99m (99mTc) sulfur colloid scan and percutaneous biopsy, which ...

Suspicion for Cardiac Amyloidosis (CA) led a 75-year-old male patient with fatigue, dyspnea, and palpitations to be subjected scintigraphic myocardial investigation technetium-99m-pyrophosphate (99mTc-PYP, or PYP scan) in order distinguish transthyretin-related CA (ATTR) from the light-chain (AL) form. A characteristic anamnesis of bilateral carpal tunnel syndrome, vertebral canal stenosis, sen...

Introduction. Leukocyte count, erythrocyte sediment rate and C-reactive protein are available laboratory markers which may be helpful in prediction of technetium Tc 99m dimercaptosuccinic acid (DMSA) renal scintigraphy results. None of these, however, have enough accuracy for prediction of renal injury and scar. This study was aimed to evaluate the diagnostic accuracy of urinary β2-microglobuli...

We used technetium-99m antimony colloid to visualize the bone marrow of the head of the femur within twenty-four hours after interruption of the blood supply by subcapital osteotomy and section of the ligamentum teres in thirteen rabbits and within twenty-four hours after a subcapital fracture in thirty patients. Of the rabbits, all showed loss of marrow radioactivity over the affected femoral ...

the prevalence of vesicoureteral reflux (vur) among siblings of children with vur has been reported to be from 4.7% to 51%. the incidence of vur in the general population is less than 1% but it is high in risk groups. in a prospective study we started identifying the incidence and severity of vur and renal parenchymal lesions in the siblings of patients known to have urinary tract infection (ut...

The appearance of a hot kidney on bone scintigraphy is rare and can be seen due to various factors. In our clinic, we observed hot kidney appearance in two patients to whom technetium-99m methylene diphosphonate (Tc-99m MDP) whole body scan has been performed: a young male adult at the age of 18 who was diagnosed with acute lymphocytic leukemia with a presumptive diagnosis of avascular necrosis...

BACKGROUND The lead mobilization test reflects the mobilizable and likely toxicologically active fraction of the lead body burden. We propose a safe and convenient protocol for this test, to assess concomitant copper and zinc excretion and to determine the size of the chelatable lead pool in nonoccupationally exposed adults. METHODS The study population included 80 white adults: 40 controls [...
