    Blunt renal trauma in children with previously undiagnosed pre-existing renal lesions and guidelines for effective initial management of kidney injury
    (Wiley, 2002) Önen, A; Kaya, M; Cigdem, MK; Otçu, S; Öztürk, H; Dokucu, AI
    Objectives To record pre-existing renal lesions (PERL) found incidentally during evaluation for blunt renal trauma in children. determine their importance. suggest guidelines for the effective initial management of children with significant renal trauma and to evaluate the role of temporary percutaneous nephrostomy tube drainage (TPND) in these patients. Patients and methods We reviewed 338 children who were hospitalized with blunt abdominal trauma between 1992 and 2000. Thirty-one patients had significant renal injury, 17 before 1997 (reviewed retrospectively) and the others reviewed and followed prospectively. Results Eleven of the 31 children had a PERL. which had been undiagnosed before the injury. The mean (range) follow-up was 52 (15-104) months. There were 22 boys and nine girls (mean age 9.1 years, range 2-13). The mean age was lower in patients with a PERL than in children with isolated renal injury. The most common cause of blunt renal injuries was a fall (45%) followed by motor vehicle accidents. Renal stones were present in five children, pelvi-ureteric junction obstruction in four, megaureter in one and a renal cyst in one. The mean injury severity scores were 12 in the children with a PERL and 14 in patients without. TPND was used in seven (22%) children: four were associated with a PERL. The mean grade of injury score for the kidney was higher in patients with a PERL and in children who underwent TPND than in patients who previously had a normal kidney and in children who did not undergo TPND. Early surgical intervention was required in three children; all were associated with a PERL. Of the 13 children who underwent surgery 11 had previous disease. Conclusions The frequency of PERL is high (36%) in children with blunt renal trauma. PERL can predispose minor trauma to cause kidney injury even with no evidence of hydronephrosis. When a minor trauma results in renal injury, it is important to seek a PERL. In selected patients. TPND may decrease the length of hospital stay and improve the outcome of the injured kidney. thereby decreasing the need for further surgery in those with isolated renal injury: however, it appears not to decrease the need for later operations in children with a PERL.

    Epidemiology and control of nosocomial infections in paediatric surgery
    (W B Saunders Co Ltd, 2002) Önen, A; Cigdem, MK; Geyik, MF; Kökoglu, ÖF; Otçu, S; Öztürk, H; Dokucu, AI
    The purpose of this study was to determine the epidemiology and control of hospital-acquired infections (HAI) in paediatric surgery. We reviewed 2844 hospitalized children in a paediatric surgical clinic between January 1997 and December 2000. The diagnosis of HAI was made based on criteria proposed by Centers for Disease Control and Prevention (CDC). The incidence, type of micro-organisms and infections, age, sex, risk factors, and the economic aspects were recorded. The mortality, duration of hospitalization and economic aspects of patients were compared with 78 control patients matured for age, sex and primary illness and free of HAI. There were 78 children with HAI, the overall incidence was 2.74% (4.99% in 1997, 3.89% in 1998, 1.33% in 1999, 1.44% in 2000). The most frequent infections were surgical wound (28 patients) and urinary tract (25 patients). The most frequent risk factors were urethral catheterization (10.26%), trauma (9.25%), and parenteral nutrition (8.70%). Mean hospitalization was 16 days (range 4-28 days) in patients with infection compared with nine days (range 2-22 days) in control group. Eight patients died in the infection group, while two died in the control group. HAI caused a significant increase in mortality, prolonged hospitalization and increased costs (P < 0.05, P < 0.001, P < 0.001, respectively).
