BACKGROUND Symptoms and signs of acute tubulointerstitial nephritis (ATIN) are nonspecific; therefore, renal biopsy is often necessary to clarify the diagnosis. The aim of this study was to evaluate the use of 99mTc-dimercaptosuccinic acid (DMSA) scintigraphy in the diagnosis and follow-up of ATIN. METHODS We retrospectively reviewed the charts of five patients (nine renal units) with a media...

Metal toxicity represents a significant public health concern and contributes to many toxic metal-exposure related diseases. In particular, toxic metals promote the oxidative stress in stem cells and endothelial progenitor cells (EPCs). EPCs that are presented in peripheral blood function to replenish aging damaged endothelial cells and play important role in the maintenance of vasculature and ...

BACKGROUND Differential renal function (DRF) measurements are routinely corrected for background, which mainly affects the reproducibility and accuracy of the measurement. The present study was conducted to identify the most appropriate background ROI and optimal time interval in the calculation of DRF for EC renography. MATERIALS AND METHODS Nineteen patients were studied. For determination ...

BACKGROUND Patients with compensated Child-A cirrhosis have sub clinical hypovolemia and diuretic treatment could result in renal impairment. AIM To evaluate the changes in renal functional mass as reflected by DMSA uptake after single injection of intravenous furosemide in patients with compensated liver cirrhosis. METHODS Eighteen cirrhotic patients were divided in two groups; eight patie...

Introduction: Renal length measurement is an important diagnostic clue in several urinary tract abnormalities. Although ultra sonography is the most frequent used modality for renal size estimation, renal diameter assessment by 99mTc-DMSA scintigraphy is of great value. By now, pointing to the renal size in the 99mTc-DMSA scintigraphy report has not been recommended by gui...

OBJECTIVES Lead (Pb) pollution is a serious public health problem all over the world, it especially plays severe damage role in children's health. Apart from reducing lead-induced damages, the decrease of lead accumulation is also critical. This study has been the first attempt to investigate effects of meso-2,3-dimercaptosuccinic acid (DMSA), potassium iodide (KI) and chlorophyll (Chl) on lead...

Twenty-one patients with medullary thyroid carcinoma were studied prospectively with Tc-99m (V) DMSA after surgery. Pentavalent DMSA scintigram demonstrated abnormal uptake in 13 and equivocal uptake in 6 patients. Finally, seven patients with surgical or other imaging documentation were selected for this paper. Most of these patients were asymptomatic. Six patients had hypercalcitonemia ...

OBJECTIVE The objective of this study was to investigate arsenic induced changes in blood delta-aminolevulinic acid dehydratase (ALAD) after in vitro and in vivo exposure to this element and its response to co-administration of meso 2,3-dimercaptosuccinic acid (DMSA) and monoisoamyl DMSA (MiADMSA) either individually or in combination. METHODS Rat whole blood was exposed to varying concentrat...

The clinical significance of pentavalent technetium-99m dimercaptosuccinic acid (99mTc(V)-DMSA) scintigraphy in diagnosing inflammatory bowel disease (IBD) has not yet been fully elucidated. The aim of this prospective paper was to study the above. This study included 54 patients, 22 females and 32 males (mean age: 36.68±11.49; range: 18-63 years) with IBD who came to our clinics for follow-up ...
