PURPOSE: The purpose of this study was to describe the clinical characteristics of neonatal urinary tract infection (UTI) caused by Klebsiella pneumoniae and non- Klebsiella pneumoniae UTI. METHODS: We compared clinical characteristics of 84 neonatal patients with UTI caused by Klebsiella pneumoniae who were hospitalized at the Department of Pediatricsat Han Dong University, Sunlin Hospital during the period between May, 1994 and August, 1998. The cases were divided into two groups depending upon causative organisms' Klebsiella pneumoniae UTI vs non-Klebsiella pneumoniae UTI, and the clinical characteristics of these groups were compared. RESULTS: Escherichia coli was the most common bacterial pathogen causing neonatal UTI, followed by Klebsiella pneumoniae. There was no significant difference in the sex distribution of Klebsiella pneumoniae UTI, but non-Klebsiella pneumoniae UTI showed male predominence. There were no significant differences in the incidences of hematologic, urologic, radiologic findings and perinatal complications in between these 2 groups. CONCLUSION: Klebsiella pneumoniae is the second most common pathogen causing neonatal UTI. There were no specific differences in the laboratory, symptomatologic, and radiologic findings in these two groups.

We have experienced a case of 13 ring chromosome in a 40-month-old girl who demonstrated psychomotor retardation with delayed speech, growth retardation, hearing loss(left), microcephaly, trigonocephaly with flat occiput, hypertelorism, epicanthal folds, microophthalmia, broad prominamt nasal bridge, high arched palate, micrognathia, large auricles and other anomalies. Cytogenetic studies of peripheral blood lymphocytes with differential staining of chromosomes revealed 46, XX, r13. Her parents' karyotypes were normal. We reported the case with the review of the associated literatures.

In order to observe the changes in left ventricular function during coronary artery occlusion and reperfusion, left anterior descending (LAD) coronary arteries in the anesthetized dogs were occluded for 1 hour and then reperfused for 4 hours. Hemodynamic indexes of global systolic and diastolic function and regional wall thickness changes as a regional contractile index were measured during occlusion and reperfusion. The results were as follows; 1) Indexes of global systolic function (left ventricular peak systolic pressure, peak positive dP/dt) and global diastolic function (peak negative dP/dt, time constant, left ventricular end-diastolic pressure) showed deterioration in early occlusion period (10-30 minutes) but gradually improved even if coronary occlusion persisted. Reperfusion did not induce significant changes except that peak positive dP/dt transiently deteriorated 30 minutes after reperfusion and left ventricular end-diastolic pressure decreased 1.5-2 hours after reperfusion. 2) Indexed of regional function (i.e, end-diastolic thickness and % systolic thickening of anterior left ventricular wall) deteriorated by 10 minutes' occlusion which persisted during the entire occlusion period. Reperfusion induced no significant improvement in regional contractile function compared with occlusion 60 minutes' data, which suggested reperfusion for 4 hours after 1 hour's LAD occlusion may be insufficient for the ischemic region to recover its contractility. 3) Reperfusion arrhythmia (ventricular tachycardia) was noted in most (6/9) of the dogs, one of which deteriorated into ventricular fibrillation and the others spontaneously converted to normal sinus rhythm.

BACKGROUND: Assessment of left ventricular function with conventional 2-dimensional echocardiography (2D echo) remains largely qualitative and subjective because the manual tracing of endocardial borders is laborious and tedious. An automatic border detection (ABD) echo has been recently developed that permits real-time measurements of chamber areas and cardiac function. METHODS: To determine usefulness of ABD echo, left ventricular cross-sectional areas were automatically measured from the parasternal short-axis image in 25 cases including 9 cardiac patients, and compared with those by off-line analysis of the conventional 2D echo image. RESULTS: In on-line ABD analysis, short axis end-diastolic area averaged 13.1+/-2.2cm2, end-systolic area 5.3+/-1.3cm2 and fractional area change 59.4+/-9.0% and off-line manual analysis yielded corresponding values of 14.7+/-2.5cm2, 6.2+/-1.3cm2, and 57.1+/-7.1%. The end-diastolic and end-systolic areas by both methods were significantly different, respectively. Left ventricular end-diastolic and end-systolic area and fractional area change obtained from ABD echo correlated significantly with those of off-line measurements(r=0.897, p<0.001 ; r=0.505, p<0.01 ; r=0.427, p<0.05). CONCLUSION: Thus, these facts suggest that ABD echo is useful for on-line continuous measurement of chamber areas and cardiac function.

PURPOSE: This study was performed to evaluate clinical manifestations and findings of ultrasonogram of neonatal septic arthritis and osteomyelitis. We tried to determine the value of ultrasonogram as a tool for early diagnosis of septic arthritis and osteomyelitis. METHODS: We reviewed the records of 17 patients, who were diagnosed septic arthritis and/or osteomyelitis in Departments of Pediatrics and Orthopedic Surgery, Han dong University Sunlin Hospital in Pohang between Jan. 1994 and Sep. 1998. Radiologic findings were reviewed retrospectively according to the duration of symptoms at the onset. We compared the sensitivity of ultrasonogram with other radiologic tools done within 7 days of illness. RESULTS: We compared sensitivity of each imaging study done within 7 days of illness. 20%(3/5) had abnormality in plain radiographs, 78.6%(11/14) in ultrasonogram, 28.6%(2/7) in bone scan, and 100,0%(3/3) in MRI. Deep soft-tissue swelling around the bone was the earliest sign of acute osteomyelitis in ultrasonogram. Concurrently early septic arthritis showed deep soft tissue swelling around the joint and increased synovial effusion in ultrasonogram. CONCLUSION: Ultrasonogram is not so expensive, non-invasive, not harmful to patients, and there is no need to sedate patients for examination. Comparing with other imaging studies, the sensitivity of ultrasonogram is relatively high. Ultrasonogram is a useful diagnostic tool of septic arthritis and osteomyelitis in newbom infants.
