Moon Hee Han, Sang Uk Park, Deok-Soo Kim, Jae Won Shim, Jung Yeon Shim, Hye Lym Jung, Moon Soo Park
Clin Exp Pediatr. 2007;50(5):489-492.   Published online May 15, 2007
Idiopathic renal hypouricemia is a disorder characterized by impaired urate handling in the renal tubules. This disease usually produces no symptoms, but hematuria, uric acid nephrolithiasis or acute renal failure may develop. A defect in the SLC22A12 gene, which encodes the human urate transporter, is the known major cause of this disorder. We describe a 10-month-old boy with idiopathic renal...
A Case of Partial Hypoxanthine-Guanine Phosphoribosyltransferase Deficiency Presenting as Uric Acid Lithiasis
Ji Hae Kim, Mi Jung Kim, Kee Hwan Yoo, Young Sook Hong, Joo Won Lee, Soon Kyum Kim
Clin Exp Pediatr. 2004;47(9):1020-1023.   Published online September 15, 2004
The deficiency of enzyme hypoxanthine-guanine phosphoribosyltransferase(HPRT) results in hyperuricemia and subsequently manifests in diverse symptoms. Lesch-Nyhan syndrome is a disorder characterized by hyperuricemia, mental retardation, choreoathetosis, spasticity and self-mutilation, resulting from complete deficiency of the enzyme, whereas partial deficiency of the enzyme shows symptoms of milder forms more often without abnormal neurologic signs. A 7-year-old boy with normal growth and...

Clin Exp Pediatr. 2004;47(5):532-534.   Published online May 15, 2004
Purpose : The aim of this study was to determine the role of renal ultrasonography in neonates with isolated preauricular tags. Methods : We performed a retrospective study of 10,997 newborn infants delivered from January 1995 to June 2003 in Wonkwang University Hospital. Nineteen newborns born with isolated preauricular tags were assessed for renal anomalies by performing renal ultrasonography within one...

Lesch-Nyhan syndrome is an X-linked recessive disorder characterized by hyperuricemia, choreoathetosis, spasticity, mental retardation, and compulsive, self-injurious behavior. This disorder results from a complete deficiency of the purine salvage enzyme, hypoxanthine-guanine phosphoribosyl transferase(HPRT). We report here on a case of Lesch-Nyhan syndrome in a 1-year, 7-month-old male who presented with frequent vomiting, failure to thrive, and developmental delay. The diagnostic...
A Case of Branchio-Oto-Renal Syndrome

Branchio-oto-renal(BOR) syndrome is an autosomal dominant disorder. The pathophysiology of this syndrome is unknown. BOR syndrome has a wide range of clinical manifestations affecting the branchial, auditory and renal systems. Associated abnormalities of the face, lacrimal duct, palate and ureters have also been described. However, the major clinical findings associated and/ or ear pits, and renal anormaly. We experienced a case of a 15-day-old male...

Clin Exp Pediatr. 1999;42(10):1419-1425.   Published online October 15, 1999
Purposes : We studied the clinicial findings of oliguric acute renal failure(ARF) developed on admission or during treatment of other diseases. Methods : We performed a retrospective analysis of medical records of 118 patients with oliguric ARF who had been admitted to Kyunghee University Hospital since January 1988 to December 1997. Diagnostic criteria of oliguric ARF are serum creatinine>1.0mg/dl and urine...
Age Related Ca, Phosphorus, Uric acid concentration in Serum & Urine and Ca/Cr ratio, Cua/Ccr & TRP
Jah In Kim, Sang Joo Han, Hong Jin Lee, Won Il Park, Kyung Ja Lee
Clin Exp Pediatr. 1996;39(10):1405-1413.   Published online October 15, 1996
Purpose : There are many methods for the evaluation of the renal function. The proximal tubule of the nephrons have a role of reabsorption of the materials such as water, electrolytes, glucose, amino acids, and small molecular weight protein through the glomerular filtration. Therefore if abnormality is in the proximal tubule, these materials can be changed both in serum & urine. It is very...

Kyu Young Kim, Il Soo Ha, Hae Il Cheong, Yong Choi
Clin Exp Pediatr. 1995;38(1):129-132.   Published online January 15, 1995
A marked low concentration of serum uric acid(0.7-1.2mg/dl) was detected in a 14-year-old boy with recurrent episodes of gross hematuria. The hypouricemia accompanied with a markedly increased urinary clearance of uric acid (32.6-56.0ml/min), which was only minimally changed after both the administration of pyrazinamide, and inhibitor of the renal tubular secretion of uric acid, and the administration of probenecid, and...

Clin Exp Pediatr. 1983;26(11):1120-1124.   Published online November 30, 1983
We observed a case of hereditary spherocytosis who was a 4-month-old boy with the chief complaints of jaundice and pallor. Evidence of the same disease was also found in the patient` s father who had never been symptomatic. Diagnosis was made by presence of spherocytes in peripheral blood smear, osmotic fragility- test and autohemolysis test. A brief review of literatures was made.
