Childhood UTI is a common bacterial infection in children and frequently associated with urinary tract anomaly and high recurrent rate. Recurrent UTI and even the first UTI, if not diagnosed and untreated, may lead to serious renal scarring, a cause of childhood hypertention and end stage renal failure. It is very important to prevent the sequence of recurrent UTI and the development of renal scarring from the first UTI. However, early diagnosis is very difficult because the symptoms and signs are non-specific in young children and commonly presented with high fever only. In young infants with unexplained high fever, urinalysis and urine culture should be considered for early diagnosis. Emperic antibiotic treatment should be initiated in suspicious UTI and imaging studies of the urinary tract should be performed for the evaluation of urinary tract anomaly and renal scar in confirmed cases of UTI. Antimicrobial prophylaxis has been the common clinical practice in children with high risk factors for recurrent UTI and renal scar. In summary, early diagnosis and proper management of childhood UTI are very important to prevent hypertention and end stage renal disease by renal scar.

During the study of soil mycoflora in Jinju-shi in 1997, a dematiaceous hyphomycete, Gonytrichum macrocladum , was isolated using the soil dilute plating method. The isolate was recovered with very low frequencies and recorded for the first time in Korea. illustrated descriptions are presented for the isolate examined in the present study.

The incidence and risk factors for hypercalciuria were studied in 23 sick preterm (Group I), 36 well preterm (Group II), 16 sick term(Group III)and 41 well term(Group IV) neonates who were admitted to NICU and nursery of Ewha Woman's University Hospital from May 1988 to February 1992. The results were as follws: 1) The incidences of hypercalciuria were 73.9% in sick preterm (Group I) and 56.3% in sick term (Group III) which were significantly higher than 13.9% of control preterm (Group II) and 7.3% of control term (Group IV). Maximal urinary Ca/Cr ration were 0.63+/-0.503 in group I and 0.50+/-0.513 in group III, significantly higher than 0.19+/-0.142 of control term and 0.17+/-0.131 of control term. 2) In sick neonates with hypercalcuria, birth wight and gestational age were significantly lower and the frequencies of frosemide and intravenous calcium therpy were significantly higher than those of sick neonates without hypercalciuria. 3) In sick neonates, furosemide increased the incidence of hypercalciuria to 90.9%, significantly higher than 57.1% in neonates without furosemide. Maximal urine Ca/Cr ratio 24 hour urine calcium were also significantly higher in neonates with furosemide than those of neonates without furosemide. 4) In sick neonates, intravenous calcium gluconate increased the incidence of hypercalciuria to 86.6%, significantly higher than 54.2% in neonates without intravenous calcium. Maximal urine Ca/Cr ratio and 24 hour urine calcium were also significantly higher in neonates treated with IV calcium than those of neonates without IV calcium. 5) Calcium intake and maximal random urine Ca/Cr ratio were positively correlated (r=0.46, p=o.037). In conclusion, the majority of sick newborns in our intensive care unit were hypercalciuric. Sick condition, premature, furosemide and intravenous calcium gluconate were the risk factors that could lead to hypercalciuria. Use of these agents in sick neonates especially preterm neonates requires careful monitoring of urine calcium excretion.

OBJECTIVE: To evaluate the results of second-trimester maternal serum triple-marker screening test for Down syndrome and open neural tube defects in singleton pregnancies conceived from in vitro fertilization, the screen positive rates and triple-marker level of patients conceiving singleton pregnancies by IVF were compared to those of pregnancies conceived naturally. METHODS: Two hundred singleton pregnancies conceived by IVF and naturally conceived pregnancies who had done maternal serum screening test during the second trimester were analyzed from January 1995 to April 1998. RESULTS: One (0.5%) of the 200 cases of IVF singleton pregnancies had a positive result for Down syndrome compared with 1% of screen positive rate in the 200 cases of naturally conceived pregnancies. The median level of the triple markers were 0.92 multiples of the median(MoM) for alpha-fetoprotein(AFP), 1.44 MoM for unconjugated estriol(E3) and 0.87 MoM for human chorionic gonadotropin(hCG) respectively. CONCLUSION: The positive rate of triple test for Down syndrome and open neural tube defect in the two groups were significantly not different. As additional data are collected, corrected standards should be determined.
