Endoscopic treatment with Deflux for refluxing duplex systems.

PURPOSE: The aim of this study was to review the experience of a single institution with the endoscopic Deflux (Q-Med Scandinavia, Uppsala, Sweden) procedure and assess its effectiveness in the treatment of refluxing duplex systems. MATERIALS AND METHODS: A retrospective review of all patients that underwent endoscopic Deflux treatment for vesicoureteral reflux (VUR) in duplex systems between June 2003 and July 2007 was performed. Data collection included: age, gender, side of refluxing ureter, preoperative radiologic grade of VUR on a voiding cystourethrogram (VCUG), presence of VUR on a radionuclide VCUG 3 months postprocedure, volume of Deflux injected, number of Deflux injections performed per patient, and number of patients that underwent reimplantation surgery. RESULTS: Sixteen patients with duplex systems, two being bilateral, for a total of 18 duplex ureteral systems, underwent the Deflux procedure. Grades of reflux were as follows: grade II: 4 ureters; grade III: 8 ureters; grade IV: 4 ureters; and grade V: 2 ureters. Deflux injection volume ranged from 0.28 to 1.5 cc (mean, 0.84). Fourteen ureteral systems required one injection, three required two injections, and one required three injections. The overall success rate of the procedure after a maximum of three injections was 94%. One patient with preoperative unilateral grade V reflux had persistent high-grade reflux after two injections and opted to proceed with surgical reimplantation. The mean follow-up was 24 months (mean, 6-48). CONCLUSIONS: We conclude that the Deflux procedure is a safe, effective minimally invasive treatment alternative for patients with refluxing duplex systems.

The deflux procedure reduces the incidence of urinary tract infections in patients with vesicoureteral reflux.

PURPOSE: The aim of this study was to review the experience of a single institution with the Deflux (Q-Med Scandinavia; Uppsala, Sweden) procedure and assess its effectiveness in reducing the incidence of urinary tract infections (UTIs) in children with vesicoureteric reflux (VUR). MATERIALS AND METHODS: After institutional review board approval, the charts of 100 patients with VUR, who presented between June 2003 and June 2005, were prospectively reviewed. Data collected included: demographics, the number of preoperative and postoperative UTIs, a radiologic grade of VUR on a voiding cystourethrogram (VCUG) and the presence of VUR on a radionuclide VCUG 3 months after the procedure. Patients were continued on oral antibiotics until urine culture at 3 months was negative and no reflux was demonstrated on VCUG. The student's t test was used for data analysis. RESULTS: The mean age was 3.8 +/- 0.3 years, and 76% were girls. From 155 ureters treated, 10 had Grade I reflux, 42 Grade II, 76 Grade III, 25 Grade IV, and 2 Grade V. A second injection was required in 22 ureters (14.2%). The overall success rate of the procedure (Grade 0 reflux at 3 months) was 77.4% after the first injection and 83.9% after a second injection. The success rate per grade was: 100% for Grade I, 88.1% for Grade II, 86.8% for Grade III, 64% for Grade IV, and 50% for Grade V. The mean follow-up was 446 +/- 20 days. The mean volume injected/ureter was 0.6 +/- 0.03 mL. Thirteen (13) patients had UTIs after the procedure, compared to 75 before. There was a 5-fold reduction in the incidence of UTIs/year, from a mean of 0.68 +/- 0.09 pre- to 0.12 +/- 0.04 postinjection (P = 0.001). The majority of UTIs were caused by Escherichia coli (74% pre- and 82% postinjection). CONCLUSIONS: We conclude that the Deflux procedure is effective not only in eliminating VUR on radiologic studies, but also in reducing the incidence of UTIs and antibiotic use in children with VUR.

Ductal carcinoma in situ in a 16-year-old adolescent boy with gynecomastia: a case report.

Ductal carcinoma in situ (DCIS) of the male breast is rare. Even more rare is the finding of DCIS in association with gynecomastia. After an extensive literature search, only two cases have been reported in the literature, both in adults. Here we present the case of a 16-year-old adolescent boy who presented with pubertal gynecomastia that was treated with bilateral subcutaneous mastectomies. A DCIS focus was found in the right breast specimen, and the patient underwent bilateral completion total mastectomies uneventfully. Despite its rarity, surgeons should be aware of the possibility of the breast of adolescents with gynecomastia harboring a neoplastic focus.

Geographic information system localization of community-acquired MRSA soft tissue abscesses.

BACKGROUND: Soft tissue infections with methicillin-resistant Staphylococcus aureus (MRSA) pose an ever-increasing risk to children in the community. Although historically these infections were limited to children with prolonged hospitalization, the authors have seen an increase in community-acquired infections in children without identifiable risk factors. The goal of this study is to determine the incidence of truly community-acquired MRSA soft tissue infections in our community and geographically map regions of increased risk. METHODS: After obtaining the institutional review board's approval, a retrospective chart review was conducted on 195 patients records who underwent an incision and drainage of soft tissue infections from January 1, 2000, to December 31, 2003. Thirteen patients were excluded from the study because no cultures were taken at the time of incision and drainage. RESULTS: The most common organism isolated from wound culture was S aureus , 40% (73/182), of which 45% (33/73) were MRSA. Eighty-one percent (27/33) of MRSA infections were in Springfield, 1 of 18 towns represented in the patient population. Geographic information system analysis identified a significant MRSA cluster 1.96 km in diameter within the city of Springfield. CONCLUSIONS: Geography proved to be a significant risk factor for presenting with MRSA infection. Geographic maps of antibiotic resistance can be used to guide physician antibiotic selection before culture results are available. This has significant implications for the health care provider in proper antibiotic selection within the community.

Perforated appendicitis: is laparoscopy safe?

OBJECTIVE: The purpose of this study was to demonstrate the safety and efficacy of laparoscopy in children with perforated appendicitis. METHODS: This is a retrospective review of consecutive patients under the age of 18, operated on for perforated appendicitis between September 1997 and December 1999. RESULTS: Sixty-nine patients were operated on for perforated appendicitis. Eleven appendectomies were performed laparoscopically. Fifty-four patients underwent an open appendectomy. Four laparoscopic appendectomies were converted to an open procedure. The mean operative time was 79 minutes for the laparoscopic group, and 87 minutes for the open group. The mean length of hospital stay was 5.4 days versus 7.6 days for the laparoscopic and open groups, respectively. Neither of these differences was statistically significant. CONCLUSIONS: The above data support the use of laparoscopy in the management of perforated appendicitis in children. In conclusion, laparoscopy is as safe as open appendectomy. Laparoscopy is an effective alternative with a shorter length of hospital stay compared with that for an open appendectomy for perforated appendicitis in children.

Pediatric hand treadmill injuries.

The great popularity of physical fitness in modern society has brought many pieces of exercise equipment into our homes for convenience and privacy. This trend has come with an increasing rate of injuries to children who curiously touch moving parts, including treadmill belts. Experience with a recent series of treadmill contact burns to children's hands is described in this article. A retrospective chart review at a tertiary referral center from June 1998 until June 2001 found six children sustaining hand burns from treadmills. The patients' ages at presentation ranged from 15 to 45 months (average of 31 months, three boys and three girls). All injuries occurred in the home while a parent was using the treadmill. Burns involved the palmar aspect of the hand, mostly confined to the fingers, and the severity ranged from partialto full-thickness burns. All patients were initially managed with collagenase and bacitracin zinc/polymyxin B powder dressings to second- and third-degree burns, along with splinting and range-of-motion exercises. Two patients required skin grafting at 2 weeks and 2 months for full-thickness tissue loss and tight joint contracture, respectively. At an average follow-up of 12 months, all patients had full range of motion and no physical limitation. The rate of children injured by exercise equipment is expected to increase. Friction burns to the hands remain a concern, although early recognition and appropriate management are associated with excellent functional outcomes. Protective modification of exercise machines seems to be the best approach to eliminating these injuries.

Preoperative chemoembolization for unresectable hepatoblastoma.

Complete surgical resection offers the only chance for cure in patients with hepatoblastoma (HB). Patients with unresectable lesions are given preoperative chemotherapy in an attempt to create a resectable lesion. We present a case of an 11-month-old with an unresectable stage III HB unresponsive to systemic chemotherapy. Transfemoral hepatic-artery chemoembolization resulted in a surgically resectable tumor. The patient underwent a right trisegmentectomy with complete resection of the tumor and remains tumor-free 24 months postoperatively. Salvage chemoembolization can be an effective preoperative modality to convert an unresectable tumor into a resectable one.
