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.

Perinatal asphyxia can cause ischemic injury to immature kidney of neonates. Proximal renal tubule is the most sensitive area, showing various manifestations ranging from mild reversible injury to irreversible tubular necrosis. Aminoglycosides can be nephrotoxic in therapeutic range in immature or damaged kidney. Thess are the very important factors to be taken into corsideration on fluid therapy and nephrotoxic drugs in neonates. The purpose of this study is to detect renal dysfunction resulting from asphyxia and gentamicin treatment. The results were as follows; 1) Urinary 2-microglobulin concentration was significantly higher in neonatal asphyxia group irrespective of meconium stain (p<0.05). The group with neonatal asphyxia only (Ia) showed a gradual decline in urinary 2-microglobulin concentration and no significant difference shown when compared with control group on 7 days old (p>0.05). The group with neonatal asphyxia and meconium stain (Ib) received gentamicin for 7 days. Their urinary 2-microglobulin concentration dropped on 4 the day and increased again on 7 th day (p<0.05). The group with meconium stain only(3) showed no significant difference in urinary 2-microglobulin concentration when compared with control group (p>0.05). 2) No differences were shown in serum creatinine, serum sodium level and urinary creatinine concentrations between each group (p>0.05). 3) No differences were shown in creatinine clearance between each group (p>0.05).Fractional excretion of urinary sodium (FENa) was significantly higher on lst day in group, I, but no differences were shown afterwards (p>0.05). 4) There is no relationship between urinary 2-microglobulin concentration and serum creatinine level, creatinine clearance of FENa. 5) No differences were shown in incidence of renal dysfunction between each group. In conclusion, acute tubular injury by perinatal asphyxia recovered soon after birth. But nephrotoxic gentamicin worsened the recovering tubular injury. In case of mild fetal hypoxia without neonatal asphyxia, proximal tubular injury was not significant.

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.
