PURPOSE: Urinary tract infection(UTI) in children may be cause of end stage renal failure and hypertension. So, early detection of renal scar, vesicoureteral reflux(VUR) and anomaly, and proper management are important. We carried this study to observe the significance of 24 hours urine beta2-microglobulin(beta2-MG) for predicting renal injury and correlation of beta2-MG with the grade of VUR. METHODS: We evaluated 52 patients with UTI who were admitted to the department of Pediatrics, Sung-Ae General Hospital from April 1994 to December 1994. All patients were evaluated with 99mTc-2,3-dimercaptosuccinic acid (DMSA) renal scan, voiding cystourethrogram(VCUG) and 24 hours urine beta2-MG. We divided them into 3 groups, group A; renal scarring in DMSA scan and no reflux in VCUG(14 patients), group B; renal scarring and reflux (10 patients), and group C; no renal scarring and reflux (24 patients). RESULTS: 1) Among 52 patients, 31 patients(59.6%) were less than 1 year of age and 21 patients(40.4%) were older than 1 year. The sex ratio of male to female was 1.6:1. 2) Among 24 patients with renal scarring, 15 patients(63%) were less than 1 year of age, and vesicoureteral reflux was observed in 10 patients (41.6%). 3) Vesicoureteral reflux was seen in 14 patients (26.9%): one with grade I, four with grade II, six with grade III, one with grade IV, and two with grade V. 4) The values of 24 hours urine beta2-MG in group A and B were 3.94+/-6.13mg /g Cr and 3.72+/-5.38mg/g Cr respectively, while 0.85+/-0.63mg/g Cr in group C, showing significant difference between group A and group C(p<0.05). However, there was no significant difference between group A and B(p>0.05). The grade of vesicoureteral reflux was also significantly correlated with the level of 24 hours urine beta2-MG. 5) 24 hours urine beta2-MG was significantly decreased with improvement of renal scarring after successful treatment of urinary tract infection. CONCLUSIONS: Measurement of 24 hours urine beta2-MG can be used as a sensitive marker of the severity of UTI and also useful for the evaluation of successful treatment and prognosis of patients with urinary tract infection.

PURPOSE: To evaluate the effectiveness of a periosteal sleeve preserced fibular strut graft for the minimization of donor site complications. MATERIALS AND METHODS: Between September 1998 and March 2005, 20 patients who were followed for more than 12 months after the fibular sturt graft for a bone defect using a periosteal sleeve preservation technique were evaluated. The mean age was 13.3 years (range, 2-29 years) and the mean follow-up period was 16.2 months (range, 12-36 months). RESULTS: The mean time for the union of the primary disease was 3.3 months (range, 2-6 months) and for regeneration of the donor site was 9.1 weeks (range, 4-12 weeks) in 13 cases. Partial regeneration developed in 6 cases and there was no regeneration in 1 case. There were 2 cases of donor site complications. CONCLUSION: The new fibular strut graft technique is very effective method for reconstruction of a bone defect with a minimization of the donor site complications particularly in children.

Colonic lipomas are the second most common benign tumor of the large bowel; because they are small, they are usually asymptomatic. If there is bleeding or obstruction, however, surgical management is mandatory. These tumors may have a broad-based pedicle, and their diameter is usually less than 3cm. We report a case of colo-colonic intussusception due to certain unique features of this colonic lipoma; a narrow pedicle, giant size, and severe necrosis.
