Bakground : Patient-Controlled Analgesia (PCA) has become popularized for postoperative pain control. Theoretically, addition of a basal infusion would ameliorate the pain control as related to less need for additional demands. Regardless of theoretical background, usefulness of a basal infusion in PCA is controversial. Therefore, in this study we compared the analgesic consumption between PCA only and PCA plus basal infusion and assessed if the use of a basal infusion improves the analgesic efficacy in intravenous PCA. METHODS: 40 patients undergoing caesarian section, were assigned randomly to PCA only group (group 1) and PCA plus basal infusion group (group 2). Group 1 was programmed to deliver 1.5 ml of bolus infusion with 10 minutes of lockout interval and four times per hour of the maximum usage of patient control module. In group 2, 0.5 ml of basal infusion was added to the same PCA. The analgesic solution contained 60 mg of morphine, 180 mg of ketorolac and 5 mg of droperidol in total volume of 60 ml. PCA was started at the time of the peritoneal closure with 2 ml of loading dose in all patients. Postoperative assessments were pain score, sedation score, side effect, total analgesic consumption and the degree of patients, satisfaction. RESULTS: Total analgesic consumption was significantly greater in group 2 than in group 1. Pain score, sedation score, complication and the degree of the satisfaction were almost the same at all time interval in each group. CONCLUSION: We concluded that there was no significant benefit of basal infusion in intravenous PCA after caesarean section.

OBJECTIVES: This study evaluates the change of the left atrial appendage function before and after electrical cardioversion to understand the mechanism involved in systemic thromboembolism of atrial fibrillation. BACKGROUND: Systemic thromboembolism associated with electrical cardioversion of atrial fibrillation is thought to originate from the left atrium or left atrial appendage, or both.However, the mechanism involved is poorly understood. METHOD: We studied left atrial appendage function funcction with transesophageal echocardiography in 15 patients with atrial fibrillation before and after successful electrical cardioversion. We measured left atrial appendage emptying and filling velocities and left atrial appendage areas. Also we analysed the characteristic Dopper flow pattern of LAA. RESULT: Left atrial appendage emptying velocities before cardioversion were greater in patients without(32.0+/-13.2cm/sec) than in those with(21.4+/-7.6cm/sec) spontaneous echo contrast(SEC). Furthermore emptying velocities after cardioversion were significantly reduced group with (21.4+/-7.6 vs 12.2+/-9.6, p<0.05) and the groupwithout(32.0+/-13.2 vs 18.1+/-10.2, p<0.05)SEC. CONCLUSION: After electrical cardioversion for atrial fibrillation left atrial appendage function is impaired. These observations suggest that stunned left atrial appendage after cardioversion may predispose to thrombus formation, which may play a role in the mechanism involved in the occurrence of thromboembolism after cardioversion.

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.

A fine needle aspiration biopsy specimen of a retroperitoneal mass in a 26-year-old man who had had an orchiectomy for seminoma was submitted for cytologic evaluation. Cytologic features of the specimen included uniform neoplastic cells found singly or in groups of several cells intermingled with lymphocytes in a characteristic foamy, lacelike background. These cells varied from 10 to 20 m in diameter. The nuclei were round to ovoid with fine or reticular chromatin and one or more prominent nucleoli. The poorly defined cytoplasm stained pale-blue or blue with cytoplasmic vacuoles. The cytologic appearance was consistent with seminoma. Documented reports of the cytological appearance of seminoma are rare. The diagnosis of primary gonadal seminoma by fine needle aspiration biopsy is probably not indicated since the treatment of a primary gonadal tumor, regardless of its histogenesis, requires surgical resection. However, fine needle aspiration biopsy is extremely valuable in the diagnosis of extragonadal as well as metastic and recurrent seminoma.

In the antero-posterior and lateral viewe of the lumbar X-ray film of 258 normal Korean adults(120 males, 138 females), the following measurement was made ; the measurement of the interpeduncular distance, anteroposterior diaameter, width of the lumbar vertebral body and height, and thickness of the pedicle. The mean value of interpeduncular distances and anteroposterior diameter of each lumbar vertebral level was measured in relation to the variables of sex and age. The value of interpeduncular distance at each level was related to the pedicle index and width of the vertebral bodies. Statistical analysis was made. The percentage of type A was 74.42%, type B 21.32%, type C 4.26%, but type D was not observed. The mean value of the interpeduncular distances of each level of the lumbar vertebra was measured. In male, Ll was 23.57mm, L2 24.29mm, L3 25.36mm, L4 27.09mm, and L5 was 29.77mm. In female, Ll was 22.24mm, L2 23.03mm, L3 24.11mm, L4 25.70mm, and L5 28.29mm. The difference between male and female was significant (P<0.05). The difference between each age group was not signifcant (F>3.58). There was no significant relationship between the interpeduncular distance, anteroposterior diameter, pedicle indices and the width of the body at all levels.

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.

In two female siblings, growth and developmental retardation, poor sucking, anorexia, floppiness and respiratory difficulty developed around 2 and 4 monthes of age in each, and the respiratory symptoms rapidly aggravated to comatose states and finally into death one month later. On admission at emergency room, severe acidosis and high lactate and pyruvate levels in serum and cerebrospinal fluid were revealed in one. Brain computed tomography and magnetic resonance imaging revealed identical bilateral involvement of putamen in both of the sibs, which made the diagnosis of Leigh disease(subacute necrotizing encephalomyelopathy) possible. There is also a family history of early death in infancy period; an elder sister and a brother of mother died with unknown cause at their 5 and 10 months of age. Mitochondrial enzyme functions could not be assayed.
