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.

Macrostomia is a relatively rare malformation. There have been many surgical methods for the correction of macrostomia. The old method, a simple straight line closure , did not include reconstruction of the orbicularis oris muscle. Postoperatively, a depressed scar and severe contraction on the cheek were found, especially with animation. As a result, many authors have known that reconstruction of the orbicularis oris muscle was very important to avoid a depressed scar for the correction of macrostomia. The tendency toward lateral displacement of the reconstructed commissure has been attributed to linear scar contraction, and Z-plasty is advocated to prevent this deformity. However, we found that the Z-plasty scar may be conspicuous when the patient smiles. So we performed reconstruction of the orbicularis oris muscle to avoid a depressed scar, and straight line closure to avoid a conspicuous scar. In order to prevent linear scar contracture due to straight line closure, we overcorrected the new commissure. We treated 6 cases of macrostomia form May 1, 1996 to April 30, 1999 using straight line closure and reconstruction of the orbicularis oris muscle. Periods of follow-up were from 12 months to 35 months, with an average of 20,2 months. Every patient was analyzed clinically by ordinary scale method and anthropometrically by the ratio of abnormal distances to normal distances between cheilion and crista philtri. In 3 clinical assessments : symmetry of the commissure was excellent: degree of the scar at rest was good: and degree of depression with animation was excellent. The anthropometrical ratio was 1:1.05. Despite the fact that the linear scars were perpendicular to the minimal skin tension lines, the scars were inconspicuous. The muscle repair provided reconstruction to the modiolus and gave a natural appearance to the commissure, however it did not seem to provide sufficient bulkiness around the commissure. The straight line skin closure and repair of the orbicularis oris muscle provide effective functional and aesthetic reconstruction.
