PURPOSE: Retroperitoneal paraganglioma is a relatively uncommon neurogenic tumor, arising from paraganglial tissue. In our knowledge, there is few report about the radiologic findings of extraadrenal paraganglioma, therefore, here we document the adiologic findings of retroperitoneal paraganglioma with pathologic correlation. MATERIALS AND METHODS: In 5 patients with surgicopathologically confirmed extraadrenal paraganglioma and 1 clinjcolaboratorily confirmed case, we analyzed the ultrasonographic, computed tomographic and MRI findings, and correlated them with gross pathologic specimen. RESULTS: The location of the tumors was medial aspect of left kindey(n=2), superomedial aspect of right kidney hilum(n=2), and organ of Zuckerkandl area(n=2), UItrasonoram showed well-marginated mass(n=5), occasionally with irregular central necrosis with or without partially echogenic area suggesting hemorrhage(n=2). CT scan also showed well-marginated mass(n=6) with hemorrhagic necrosis(n--3) and contrast enhancement. One showed are shaped calcification along the capsule, and another case showed adhesion with aorta. In MRI, solid portion of the mass showed relatively low signal intensity on T1WI, increased signal on T2WI, and enhancement with gadolinium. Necrotic portion showed increased signal intensity on T1WI, and also showed increased signal intensity on T2WI, without contrast enhancement. Grossly the mass showed internal hemorrhagic necrosis of variable degree(n=6). CONCLUSION: If well-marginated mass is noted around the area of paraganglial distribution including organ of Zuckerkandl, especially with evidence of hemorrhagic necrosis and contrast enhancement, we must consider the possibility of paraganglioma despite no characteristic symptoms.

BACKGROUND: Controversy exists as to whether or not inhalation anesthetics and intravenous anesthetics impair arterial oxygenation (PaO2) during one lung ventilation (OLV). Accordingly, we examined the effect of enflurane and propofol on PaO2 and pulmonary vascular resistance (PVR) during OLV. METHODS: Forty patients, who had prolonged periods of OLV anesthesia with minimal trauma to the nonventilated lung were studied in a cross over design. Patients were randomized to four groups; Group 1 received 1 MAC of enflurane and oxygen from induction until the first 20 min after complete lung collapse, then were switched to propofol 100 g/kg/min (P100). In group 2, the order of the anesthetics was reversed. Group 3, Group 4 received the same order of the anesthetics as Group 1, Group 2, respectively but received propofol 200 g/kg/min (P200). RESULTS: During OLV, the PaO2 values were lower than those with two lung ventilation (TLV), there were no significant differences among each groups and between propofol and enflurane in PaO2, but in the selected patients (n=10, PaO2<120 mmHg during OLV), PaO2 in propofol group was higher than that of enflurane group (p<0.05). Conversion from TLV to OLV caused a significant increase in PVR, but there were no difference in PVR between propofol and enflurane group. CONCLUSIONS: These results suggest that the usual clinical dose of propofol affords no advantage over 1 MAC of enflurane anesthesia except low PaO2 patients during OLV. Propofol might be of value in risk patients of hypoxemia during thoracic surgery when OLV is planned.

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.

The purpose of this study was to develop a standardized Nursing Diagnosis/ Intervention Protocol through a literature review and validity testing. Seven nursing diagnoses were selected as major nursing diagnosis in the field of Nutritional and Eliminative problem. The nursing intervention list was made by an expert group's review of Nursing Intervention Classification(NIC) suggested nursing interventions. Nursing activities which were included in each nursing intervention were sorted to follow the nursing intervention process after review and revision. The expert group's validity testing was done twice using the Likert scale. As a result the Nursing Diagnosis/ Intervention Protocol for Nutritional and Eliminative Problems was made to include 7 Nursing Diagnoses, 51 Nursing Interventions and 631 Nursing Activities.

OBJECTIVE: The aim of this study is to find the most helpful midsagittal reference plane for diagnosis in PA cephalometry compared with 3D CT. METHODS: The subjects consisted of 25 adults who showed no facial asymmetry by gross inspection. 3D CT and posteroanterior cephalogram of the subjects were taken. To find the most helpful midsagittal reference plane in PA cephalometry, we considered five kinds of midsagittal planes from which the distances to five landmarks were measured and compared the result with that of 3D CT. The midsagittal plane for 3D CT was determined by the landmarks Nasion, Sella and Basion. RESULTS: PA measurements using the midsagittal reference plane on a perpendicular plane lying through the midpoint of the right and left latero-orbitales was closest to those of 3D CT. CONCLUSIONS: It was considered that latero-orbitale perpendicular could be used as the helpful midsagittal reference plane to assess facial asymmetry in PA cephalometry.

Purpose: This study evaluated the diagnostic performance of contrast-enhanced voiding ultrasonography (CeVUS) for detecting intrarenal reflux (IRR) and the correlation between CeVUS-detected IRR sites and photon defect sites in acute 99mTc-dimercaptosuccinic acid (DMSA) renal scans in pediatric patients. Methods: Fifty-four kidneys from 27 patients (20 males and seven females; mean age, 5.6±4.1 months) who underwent CeVUS and acute DMSA renal scans for recurrent urinary tract infection (UTIs) or pyelonephritis were included. Pediatric experts compared the results of CeVUS with acute DMSA renal scans. Results: Thirteen renal units (13/54, 24.1%) in 10 patients (nine males and one female; mean age, 6.3±3.7 months; age range, 0 to 13 months) showed vesicoureteral reflux and eight renal units (8/54, 14.8%) demonstrated IRR on CeVUS. Ten renal units in eight patients (six males and two females; mean age, 6.9±1.4 months; age range, 2 to 13 months) showed 19 photon defects on acute DMSA renal scans. Fifty-two renal units (96.3%) showed concordant results, and two renal units (3.7%) showed discordant results between CeVUS and acute DMSA renal scans. IRR accounted for 15/19 (78.9%) photon defects in eight renal units of seven patients using CeVUS. In a per-renal-unit analysis, the sensitivity, specificity, positive predictive value, negative predictive value, and accuracy of CeVUS were 80%, 100%, 100%, 95.7%, and 96.3%, respectively. Conclusion CeVUS showed good performance in detecting IRR, and the IRR sites detected by CeVUS closely correlated with photon defect sites in acute DMSA scans. CeVUS may play an important role in managing patients with recurrent UTIs or pyelonephritis with reduced radiation exposure.

PURPOSE: Intussusception is one of the most common cause of childhood intestinal obstructions. Early diagnosis is essential to avoid treatment delays, which can increase morbidity and mortality. METHODS: In order to evaluate the factors contributing to air-reduction failure, we reviewed cases of childhood intussusception admitted via the ER and managed by air enema reduction from 1994 to 1998. They were divided into two groups and compared retrospectively by using medical records. Group I was the operation group after air-reduction failure, and group II was the air-reduction group. RESULTS: In 319 cases (279 patients), group I consisted of 112 cases (110 patients), and group II consisted of 207 cases (169 patients). No differences in age, sex, body weight, location of intussusception, laboratory findings (leukocytosis and thrombocytosis), presence of bloody stool, and body temperature were noted between the two groups. Factors significantly contributing to air-reduction failure were duration of symptoms, type of intussusception and a few physical findings (abdominal distension, palpable mass, lethargy, and vomiting). The recurrence rate of group I was significantly lower than that of group II, and most recurrences developed in the first postoperative month. CONCLUSION: Childhood intussusceptions of a non-ileocolic type with longer durations of symptoms and severe clinical findings have a higher chance of air-reduction failure.
