Many previously described nuclear medicine procedures to assess glomerular filtration rate have some problems because numerous blood sample is to be taken and they don't measure each separate renal function. Gates described isotopic method for the measurement of global and unilateral GFR based on the fractional renal uptake of (99m)Tc-DTPA 2 to 3 minutes after its intravenous injection. We evaluated GFR using (99m)Tc-DTPA in 57 people according to Gates method and compared with creatinine clearance. A good correlation was observed between creatinine clearance and GRF calculated by Gates' formula with an r value of 0.9(P<0.05). And also the relationship between parameters of (99m)Tc-DTPA renal scan images and GFR was taken. They were significantly correlated with GFR calculated by Gates' formula : r value 0.66 between relative intensity of peak renal to peak aortic activity(pK/pA) and GFR, -0.42 between time between aortic and kidney peak(A-K) and GFR and -0.48 between parenchymal renal activity at 25 min compared to peak kidney activity(25K/pK) and GRF. In conclusion, the determination of GFR according to Gates' formula shows good and reproducible of GRF with rapidity and simplicity. And the parameters from the renal scan images can use to estimate the renal function.

PURPOSE: Urinary tract infection (UTI) in children is the most common disease during the infantile period, therefore early diagnosis and treatment are important. Pyuria is a useful clinical parameter for the initial diagnosis of a UTI. In this study we aimed to compare the clinical, laboratory, and imaging findings in relation to the duration of pyuria in infants with UTIs. METHODS: Three hundred seventy-four infants <12 months of age who were admitted between January 1995 and December 2005 for the first episode of a febrile UTI were retrospectively reviewed. Patients were divided into two groups according to the duration of pyuria as follows: group 1, pyuria resolved <3 days after initial treatment; and group 2, pyuria lasted at least 3 days after initial treatment. RESULTS: There were no significant differences between the two groups in relation to gender, age, total duration of fever, and organisms in the urine. Group 2 had a significantly higher peripheral blood leukocyte count (14,360.86+/-5,526.16 cells/mm3 vs. 11,822.55+/-5,687.26 cells/mm3, P<0.001), erythrocyte sedimentation rate (32.81+/-19.34 mm/hr vs. 23.74+/-20.43 mm/hr, P<0.001), and C-reactive protein (6.84+/-5.68 mg/dL vs. 3.78+/-3.99 mg/dL, P<0.001) than group 1. There was a significantly higher incidence of hydronephrosis and a higher grade of vesicoureteral reflux (VUR) in group 2 compared to group 1. CONCLUSION: In infants with UTI, pyuria of longer duration is related to severe UTI and higher grade VUR, therefore aggressive radiologic studies may be necessary.

BACKGROUND AND OBJECTIVES: There is little clinical data on the results of using Sirolimus-Eluting Stent (SES) for treating In-Stent Restenosis (ISR). We performed this study to evaluate the clinical outcomes for implanting SES for treating ISR in a real world hospital environment. SUBJECTS AND METHODS: A total of 30 patients with 32 ISRs (males: 73.3%, mean age: 60.2) (focal lesions: 21.9%, diffuse intra-stent lesions: 34.4%, proliferative lesions: 21.9%, total occlusions: 21.9%) were treated with SES after balloon predilation was performed. We evaluated the clinical results and the performed coronary angiography after 6 months. RESULTS: All the procedures were successful. The mean SES diameter and length were 3.0+/-0.3 mm and 27.1+/-5.5 mm, respectively, and the mean acute gain was 2.42+/-0.38 mm. No in-hospital major adverse cardiac events (MACE) were observed. Twenty five patients with 27 lesions (84.4%) underwent coronary angiography at their 6 month follow-up. The late loss and loss index were 0.41+/-0.56 mm and 0.18+/-0.22, respectively. The binary restenosis rate was 7.4% (2/27 lesions). The rate of target lesion revascularization was 3.7% (1/27 lesion). The incidence of MACE at 6 months was 3.3% (1/30 patient). CONCLUSION: Treating ISR with SES is a safe and effective procedure for reducing ISR without the occurrence of acute or sub-acute thrombosis.

Emphysematous pyelonephritis is a necrotizing renal infections characterized by intrarenal and occasional perirenal gas production. Although uncommon (89 cases in the literature), it occurs almost exclusively in diabetic patients (87% of the cases). Prompt and aggressive management is required to sahage these patients. We describe a recent case of a diabetic woman with emphysematous pyelonephritis due to E. Coll, successfully managed with unilateral nephrectomy.

Blood and urine samples were taken from 447 welders exposed to manganese containing welding fumes and 127 office workers not exposed to welding fumes as a control. The air samples were analyzed by flame atomic absorption spectrophotometer (Varian 30A, Australia), and blood and urine samples were analyzed by flameless atomic absorption spectrophotometer(Z-8100, Hibachi, Japan). Data were evaluated in accordance with type of industry, smoking habits, and work duration. The results obtained were as follows: 1. The limit of detection(LOD) levels of manganese in blood and urine were 0.11 microgram/100ml of and 0.14 microgram/l, respectively. Our results of manganese concentration were shown within +/-2 standard deviation which was the upper and lower warning limit (UWL or LWL) on quality control chart. 2. The airborne concentrations of manganese in welding workplaces were 0.067 mg/m3 showing differences by type of industry ; 0.017 mg/m3 in automobile assembly and manufacturing industries, 0.084 mg/m3 in steel heavy industries and 0.180 mg/m3 in shipyards. 3. The blood manganese concentrations showed differences by type of industry showing the highest values of 1.70 microgram/100m1 in shipyards, 1.24 microgram/100m1 in automobile assembly and manufacturing industries and 1.11 microgram/100ml in steel heavy industries. Urinary manganese concentration corrected by urinary creatinine concentrations was 0.34 microgram/g creatinine in automobile assembly and manufacturing industries, 0.43 microgram/g creatinine in steel heavy industries and 0.48 microgram/g creatinine in shipyards. There were no difference urinary manganese concentrations by type of industry. 4. The overall blood manganese concentration was 1.26 microgram/100ml, and urinary manganese concentration was 0.35 microgram/g creatinine in welders. In contrast to these values, blood and urinary manganese concentrations were lower in control group showing 0.73 microgram/100m1, and 0.28 microgram/g creatinine, respectively. 5. Smoking habits did not seem to affect on blood and urinary manganese concentrations both in welders and office workers. 6. Blood manganese concentrations were significantly higher in welder who had worked longer than 10 years than in welder who had worked less than 10 years. 7. The blood manganese concentrations were significantly correlated to airborne manganese concentrations(r=0.318, n=64), work duration(r=0.425, n=538), and cumulative exposure indices(CEI) (r=0.354, n=64).
