PURPOSE: Hemolytic uremic syndrome(HUS) is the most common cause of renal failure in childhood in western countries, but it has been a relatively rare disease in Korea. To analyze the clinical and epidemiologic characteristics of HUS in Korea, we reporte our experience, METHODS: We reviewed retrospectively the medical records of 9 patients who were diagnosed the hemolytic uremic syndrorne at Pusan National University during the period from January 1984 to December 1998. RESULTS: The age at presentation ranged from 3 years to 12 years old(mean: 5.9 years). Six of the children were typical and three patients were atypical. Six cases had grossly bloody stools and seven had abdominal pain. Oliguria developed in four cases and gross hematuria in eight cases. One case had seizure and letargy. Verotoxin producing E. coli(VTEC) were found in the stool specimens of two pa- tients. One was the serotype 0157:H7 and the other was the serotype 026:H-, Olll:H21. Verotoxin 1 (VT1) genes were identified by PCR in both of the cases. All patients required conservative treatment. Two patients were treated with peritoneal dialysis, one patient with hemodialysis and one patient with plasmapheresis. Of 9 case, 6 recovered without residual sequelae, but two patients died, and one patient progressed to end stage renal failure. CONCLUSION: Two thirds of our cases were typical type of HUS, which is now the predominant type among Korean childhood HUS sufferers. From this study, we suggest that patients diagnosed with typical HUS should be studied for the verotoxin of E. coli isolated from stool.

The intradermal (ID) test has been widely used in Korea and several reports about the results of the ID test are known. We examined the egg of Clonorchis sinensis (C.s.) by ID test in 443, stool's egg-counting technique in 79 and direct smear (cellophane thick smear technique) in 1204 subjects. The results are as follows: 1. The positive rate of C.s. was 3.8% out of 1304 persons. 2. The sensitivity of ID test was 82.1% out of 39 persons and the specificity was 64.6% out of 404 persons. 3. The false positive of ID test was 35.4% out of 404 persons and, the false negative was 17.9% out of 39 persons. Intradermal test is a rapid, sensitive and useful supplementary diagnostic tool for the detection of Clonorchiasis infection and must be used as screening test with direct smear of stool but cross reaction with other helminth infections and moderate false reaction are the main disadvantages in its practical application.

Congenital adrenal hyperplasia(CAH) is a recognized cause of precocious pseudopuberty. Some children with CAH also develop true precocious puberty with early maturation of the hypothalamic-pituitary-gonadal axis. We review a case of CAH who eventually developed central precocious puberty nine months after initial treatment with corticosteroid. A 3-year-old boy visited complaining of rapid growth, a large penis and frequent penile erections. This patient was diagnosed with CAH with elevated 17-OH progesterone and cortical hypertrophy of adrenal gland on CT scan. His gonadotropin levels were within the normal prepubertal range. Even on treatment with corticosteroid he grew rapidly and had testicular enlargement, pubic hair development and rapid bone maturation. At second admission, his gonadotropin levels were elevated both basally and in response to LHRH stimulation, suggesting that the CAH led to early activation of pubertal gonadotropin secretion(true precocious puberty). He was treated with monthly depot injections of a LHRH analog in addition to the hydrocortisone. His second sexual characteristics regressed gradually and rate of linear growth and bone maturation decreased.
