Liver abscess in children is rare in developed countries; the incidence is 25 per 100,000 admissions in USA. Common complications are pleural effusion, empyema, pneumonitis, hepatopleural or hepatobronchial fistula, intraperitoneal or intrapericardiac rupture, septic shock, cerebral amebiasis, etc. These complications may lead to death if the management is delayed. However, recent management results in a mortality of less than 15%. We report a case of liver abscess in a child. He manifested with fever and abdominal pain in the right upper quadrant. On computerized tomography scans, multiple cystic lesions were seen in both lobes of the liver and were 5 to 55 mm in size. In laboratory findings, neutrophilic leukocytosis, peripheral eosinophila, elevated values of ESR, C-reactive protein, and elevated serum AST, ALT, ALP and GGT were detected. Furthermore, we determined the organisms in the blood culture and serum. Blood culture was positive for Streptococcus spp., and amebic indirect hemagglutination antibody titer was increased to 1:512.

This study was conducted to investigate the safety of the umbilical venous blood for antologous transfusion in the premature newborn babies. Umbilical venous blood was collected with aseptic technique immediately after delivery from 270 healthy mothers admitted to the Yeungnam University Hospital between March 1,1992 and August 31,1992 . The volume of the blood and the time taken for collecting the blood were measured. Also the hematological and biochemical changes of the blood during storage in the refrigerator of blood band and the incidence of bacterial contamination were studied. It took 67.6+/-25.9 seconds on the average for collecting the blood from an umbilical vein and the average volume of the blood was 77.1+/-23.2ml which would be sufficient volume for one time transfusion of 10ml/kg of packed red blood cells for the neonates. The hemoglobin and hematocrit values did not change significantly during storage for three weeks. Thus significant hemolysis did not seem to occur during storage. However, platelet counts decreased significantly from 248+/-59x10E3/mm3 to 193+/-47x10E3/mm3(p<0.01). Although plasma calcium level was not changed (8.4+/-0.9mg/dL), sodium was decreased significantly from 184.3+/-11.1mEq/L to 170.9+/-13.9mEq/L(p<0.01) and potassium was incresed from 5.0+/-1.0mEq/L to 26.7+/-4.8mEp/L.(p<0.01). Plasma glucose level was decreased from 521.7+/-106.7mg/dL to 294.3+/-120.8mg/dL (p<0.01), blood pH and bicarbonate concentrations were decreased significantly from 6.825+/-0.110 to 6.378+/-.087 and from 13.5+/-1.6mEq/L to 2.1+/-1.0mEq/L respectively (p<0.01). The smear of the umbilical venous blood and peripheral blood of the neonates stained by KleihauerBetke method revealed no significant differences in the percentages of adult red blood cells. Also there were no differences in the percentages of adult ted blood calls in the umbilical venous blood samples according to time for collection. The degree of decrement of hemoglobins (1.2gm/dL) after delivery in the mothers who had sampling of the umbilical venous blood was not different from that in the mothers who didn't hava sampling. The bacterial contamination rate of the umbilical venous blood was 3.5% (95% confidence interval was from 0.7 to 6.3). It seems to be safe to use the umbilical venous blood in the neonates for autologous transfusion but confirmation of bacterial contamination by culture is necessary.

BACKGROUND: Echocardiography is rapidly established itself as the primary diagnostic technique for investigation of children with heart disease, and referrals are increasing to the pediatric cardiology clinic for investigation. However, because there is a lack of analysis data on the patients referred to pediatric cardiology clinics, we have proceeded to compare and analyze their characteristics to provide basic data base. METHODS: From Oct. 1, 1998 to Jul. 10, 1999, total 443 cases referred to the pediatric cardiology clinic of Yeungnam University Hospital were studied retrospectively by medical records, chest X-ray, EKG and echocardiography, etc. RESULTS: The results were as follows. 1. The proportion of male was 61.0%(261 cases) and that of female was 39.0%(167 cases). The ratio of male to female was 1.6:1. The proportion infants less than 1 year-old was 62.6%(268 cases) of all patients. 2. Cardiac murmur was present in 248 cases(57.9%), which was the most common case of referral to the pediatric cardiology clinic. The impression at referral was more congenital heart disease(70.6%) than acquired heart disease(17.8%) and arrhythmia(11.6%). 3. The final diagnosis was as follows : congenital heart disease was present in 212 cases(49.5%), acquired heart disease, 59 cases(13.9%); arrhythmia, 13 cases(3.0%); normal heart, 144 cases(33.6%). CONCLUSION: Among the patients referred to pediatric cardiology clinic, 33.6%(144 cases) had normal hearts and why these patient were referred may be possibly due to more dependence on echocardiography than on auscultation instruction. Threfore, clinical and auscultatory skill should be emphasized to minimize dependence on expensive echocardiography for evaluation of pediatric heart disease.

We evaluated the corneal topography of 109 eyes which have 1 diopter or more astimatism, with computer-assisted videokeratography(Eye Sys CAS). There was 11% with round pattern, 17.4% with oval pattern, 49.5% with symmetric bow-tie pattern, 19.3% with assymmetric bow-tie pattern, 2.8% with irregular pattern. 70% of subjects had right and left eyes classified into the same group. There was statistically significant difference among the patterns for keratometric astigmatism and difference among the groups which were classified by the location of the area of highest refractive power for keratometric and total astigmatism. The mean angular separation between flat and steep meridian was 89.2 degrees and ranged from 78.61 degrees to 100.67 degrees. The mean residual astigmatism was 0.547 diopter. In the with-the rule astigmatism type, when the total astigmatism less than 1.89 diopter, residual astigmatism neutralize the corneal astigmatism, but when the total astigmatism increase more than 1.89 diopter, residual astigmatism tend to increase the total astigmatism.
