A Case of 18q-Deletion Syndrome with Hydronephrosis and Anhydrosis
Mun Hee Kim, Kee Hwan Yoo, Young Sook Hong, Soon Kyum Kim
Clin Exp Pediatr. 1999;45(5):711-715.   Published online May 15, 1999
The 18q-syndrome is a deletion disorder that occurs in humans. Clinical symptoms are mental retardation, craniofacial anomalies, skeletal deformity, seizure, and hearing loss. 18q- deletion occurs over a broad region, spanning the interval from 18q22.2 to 18qter rather than a single critical region containing 18q. We experienced a case of 18q-syndrome in a male child. It was diagnosed by clinical...

Clin Exp Pediatr. 1994;37(8):1097-1103.   Published online August 15, 1994
The frequent occurrence of hematuria in children necessitates diagnostic evaluation. Hematuria may occur with either renal or lower urinary tract disease. Clarification of the etiology of hematuria, whether microscopic or gross, is facilited by localizing the site of bleeding to the kidney(glomerular) or the lower urinary tract (non-glomerular). The mean cellular volume (MCV) of urinary red blood cells (RBCs) of...
