GENITOURINARY SYSTEM Radionuclide studies of the genitourinary system have wide application in pediatric patients. They include renal scintigraphy, radionuclide cystography, and testicular scintigraphy. Renal Scintigraphy Early diagnosis and treatment of urinary abnormalities in children have made it possible to reduce the morbidity and mortality associated with these disorders. Radionuclide studies of the kidneys have become valuable diagnostic methods which complement radiology and ultrasonography of the genitourinary system. While information about the size, position, and shape of the renal units is available in scintigraphy, its most unique contribution is that of providing quantitative information regarding renal function. The radionuclide evaluation is done with an intravenous injection of a very small volume of radiopharmaceutical and recording with a gamma camera-computer system. Several radiopharmaceuticals can be used. The technetium-99m labeled compounds include those excreted by glomerular filtration, such as 99mTc-Sn-diethylenetriamine pentaacetic acid (DTPA), and also agents Showing varying degrees of retention by tubular cells. These include 99mTc-iron ascorbate DTPA, 99mTc-gluco-heptonate and 99mTc-dimercapto-succinic acid (DMSA). Orthoiodohippurate, labeled with 123I or 131I, is eliminated primarily by tubular excretion and is not normally retained by the kidney (Table 1). The study carries no risk and the radiation dose to the patient is lower than that of intravenous urography. Perfusion studies are obtained by rapid imaging of the kidneys following the intravenous injection of any of the technetium radiopharmaceuticals.

Renal cell carcinoma is frequently a matter of urological interest. In recent years there were significant improvements regarding the earlier diagnosis more precise preoperative staging and appropriate therapy. One hundred patients (42-78 years old) with the preoperative diagnosis of renal cell carcinoma were analyzed. Preoperative radiological evaluation included transabdominal ultrasound, intravenous urography, computer-assisted tomography, and angiography. In all patients after radical nephrectomy pathohistological diagnosis was established and patients with the confirmed renal cell carcinoma tumor staging was performed. All histological findings were compared with the preoperative results of radiological examinations. Reliability of all of them is separately determined. Our results confirmed that the most efficient method of preoperative staging was computer-assisted tomography (accuracy 93%). Diagnostic methods that were previously used like intravenous urography and angiography, were not useful for routine diagnostic purposes. Ultrasound is a precise but not an enough informative diagnostic tool (accuracy 87%). Combine used of both ultrasound and contrast computer-assisted tomography is cost-effective, and an enough precise combination for everyday use.

Saturation Kinetics

1. When [3H]thymidine was injected intravenously into rats in amounts up to 40mg/kg body wt. and the3H radioactivity in the livers measured at 30min, saturation kinetics for thymidine uptake were not found. If the animals were examined 3 min after intravenous injection, saturation could be attained in normal rats with 12mg of thymidine/kg and in partially hepatectomized rats with 4mg/kg. At concentrations of thymidine close to saturation, no differences were found in rate or amount of uptake/g of liver between normal and partially hepatectomized rats 1–2h after operation. 2. Perfusion techniques were used to compare thymidine uptakes in the two sets of rats at concentrations up to 40μm-thymidine. Uptakes with tracer amounts of thymidine after 30min were identical in vivo and in the perfusion studies and were twice as great in livers from partially hepatectomized rats with concentrations up to 40μm-thymidine. 3. At 1.5h after operation there was nearly twice as much β-aminoisobutyrate present per g of liver from partially hepatectomized as compared with normal rats.

Egalitarian Theory

Purpose: This study sought to establish the influence of SFP on children enrolment in early childhood education centers in Turkana Central Sub-County, Kenya. Specific objective was to establish the influence of food adequacy on enrolment in ECE centres in Turkana Central Sub County, Turkana County, Kenya. Methodology: The study was based on Maslow hierarchy of needs, the program theory and liberal egalitarian theory. The study used a mixed research method. The study adopted the cross-sectional research design. The target population was 250 schools, 78 teachers and head teachers and 5,000 parents in pre-schools in Turkana Central Sub County. The study used purposive sampling to select respondents. The sample size of the study was 150 schools, 60 teachers and head teachers and 357 parents. Primary data was gathered by use of questionnaires and interviews guides. Secondary data consisted of report forms of pre-schoolers. Quantitative information was analyzed using descriptive statistics which was computed using SPSS version 21. Qualitative data was analyzed using content analysis. Multiple regressions were done to analyze the influence of SFPs on children enrolment in ECDE centres in Turkana Central Sub County. Findings: The study found that food adequacy significantly and positively relate with children enrolment in ECE centres in Turkana Central Sub County, Turkana County, Kenya. Food adequacy had statistically significant effect of school enrolment in ECD (β = 0.415, P = 0.005). It implies that food adequacy significantly and positively relate with children enrolment in ECE centres in Turkana Central Sub County, Turkana County, Kenya. This implies that increasing food adequacy will lead to increase in children enrolment in ECE centres in Turkana Central Sub County, Turkana County, Kenya. Unique contribution to theory, practice and policy: The study therefore recommends the government to increase food supply to ensure adequacy. There is need to continue supply of balanced diet to children because it improves their growth and learning. Some of the children are from very poor families and during school holidays they suffer because of lack of food; the study therefore recommends orphans, poor and disabled to be fed even during holidays.

Purpose: To evaluate the suitability of 99mTc-DTPA as a radiotracer in Persian cat's renal scintigraphy.Methods: twelve adult healthy Persian cats were selected. For scintigraphy, the animals were anesthetized and 99mTC-DTPA was injected via the femoral vein as a bolus at a dose of 1.5 mCi. Immediately after intravenous injection of radiotracer, scintigraphic operation was conducted on the renal organ. dministration of the radioisotope and accumulation of radioisotope in the tissues was monitored by specific imaging  theemanatingResults: Distinct scintigraphic scans were obtained using 99mTC-DTPA. Visual comparison of the scans indicates that there was no significant difference in the accumulation of radiotracer. In dynamic scans, symmetric and concurrent distribution of 99mTc-DTPA in the kidney was observed.Conclusion: The results show that the radiopharmaceutical 99mTc-DTPA is suitable for use in Persian cat's renal scintigraphy, and this makes it potentially useful in research and clinical practice.Keywords: Kidney, Persian cat, Radiotracer, Scintigraphy, Technetium-99m diethylene triamine pentacaetic acid (99mTc-DTPA)

A comparative and dynamic analysis of the uronephrological morbidity of the adult population of the Arkhangelsk Region for 2005-2014 was conducted on the basis of the given official statistics (forms of federal statistical observation No. 12). The growth of the general and primary morbidity of the population of the Arkhangelsk Region by diseases of the genitourinary system was revealed which is connected on the one hand with the increasing in the proportion of the elderly population and more effective detection of diseases due to the new diagnostic methods, on the other hand with insufficient effectiveness of the disease prevention and screening.
