Technetium-99m-dimercaptosuccinic acid renal scintigraphy can guide clinical management in congenital hydronephrosis.

Objective: The purpose of this study was to evaluate damage of the kidney with technetium-99m-dimercaptosuccinic acid (Tc-DMSA) scintigraphy in children with congenital hydronephrosis (CH) and the influence of other postnatal associated diagnoses on abnormal Tc-DMSA findings.

Subjects And Methods: Tc-DMSA scintigraphy in 54 children (17 girls and 37 boys), aged from 2 months to 5 years (median 11 months) with 66 congenital hydronephrotic renal units (RU) (42 unilateral hydronephrosis-29 boys and 13 girls; 12 bilateral hydronephrosis-8 boys and 4 girls) was performed. Male/female ratio was 2,2:1, unilateral/bilateral hydronephrosis ratio was 4:1.

Diuretic 99mTc DTPA renography in assessment of renal function and drainage in infants with antenatally detected hydronephrosis.

Background/aim: The controversy over the postnatal management of infants with antenataly detected hydronephrosis (ANH) still exists. We presented the results of diuretic 99mTc diethylenetriamine pentaacetic acid (DTPA) renography in 30 infants with the antenatal diagnosis of unilateral renal pelvic dilatation. The aim of this study was to assess the renal function determined by the pattern of drainage and split renal function (SRF) on diuretic renography and to correlate these findings with anteroposterior pelvic diameter (APD) estimated by ultrasonography.

Possibilities of nontoxic autonomous thyroid nodules treatment by percutaneous ethanol injection.

Background/aim: According to the current principles, autonomous functional thyroid nodules are treated by surgery or by radioiodin therapy. Ultrasound guided percutaneous ethanol injection into solid tumors of the soft tissues was a starting point in attempts to treat the thyroid nodules by the same method. The aim of the study was to assess the efficiency of percutaneous injection in treating solitary, nontoxic, autonomous thyroid nodules of up to 15 mL volume.

[Assesment of lower extremities ischemic disease by thallium 201 perfusion scintigraphy in patients with diabetic angiopathy].

Background/aim: Tibial perfusion in diabetic microangiopathy is considered to be a diagnostic problem. A special place in quantifying muscle microcirculatory perfusion belongs to thallium 201 muscle perfusion scintigraphy (201T1 PS). Thallium, showing the characteristics of potassium (K+), enters a cell by means of active cell transportation and follows erythrocyte up to the tissue.

[Hyperbaric oxygenation effects determination in the therapy of chronic occlusive lower extremities arteries disease by the use of perfusion scintigraphy].

Background/aim: Hyperbaric oxygenation (HBO) is a medical treatment of a patient with 100% oxygen inspiration under the pressure higher than atmospheric in a special unit designed to let the whole patient's body rest in a chamber. The aim of the study was to determine the effect of the application of HBO treatment on the patient's lower extremities with chonic inoperabile occlusive disease by measning the parameters of perfusion scintigraphy (perfusion reserve, relative perfusion).

Methods: This investigation included 22 patients (19 males and 3 famales).

[Comparative analysis of lower extremities tissue perfusion by the use of perfusion scintigraphy method after hyperbaric oxygenation and lumbar sympathectomy].

Background/aim: Lumbar sympathectomy (LS) increases pheripheral blood flow primarily by the arteriolar vasodilatation within the skin vascular net. Increase in tissue nutrition takes place only in the distal blood vessels of the skin. Nevertheless, in some patients sympathectomy brings about improvement in ischemic ulcerations healing.

Estimation of 99mTc-ciprofloxacin accumulation indexes in bone and joint bacterial infections.

Background/aim: 99mTc-ciprofloxacin is a radiopharmaceutical preparation sintetized to improve diagnostic accuracy of bacterial infections in human tissues. It is mostly applied in diagnosis of bone and joint infections. Many papers have confirmed its sensitivity to infection, but newer papers argued its specificity.

[Significance of the determination of Doppler sonography haemodynamic indices for the assessment of distal perfusion in patients with critical ischemia of lower limbs].

Background/aim: The perfusion of tissue, especially the muscles of the lower limbs (LL), implies the blood flow that carries enough nutrition, energy materials and oxygen. The aim of this study was to determine whether the decreased Doppler sonography parameters, resistence index (RI), and pulsatility index (PI) were significant as indicatiors of irreversible ischemia of LL.

Methods: In 40 patients (mean age 66 +/- 14.

Excess secretion of any of the adrenal cortical or medullary hormones contributes to a number of well-known clinical syndromes.. They may result from benign or malignant adrenal tumours, adrenal hyperplasia or, least frequently, from extra-adrenal disease.
