To observed whether the specific IgG antibody test using ELISA was useful in diagnosis of presently ill patients of paragonimiasis, a total of 95 sera were tested. The sera were collected from 21 egg positive cases, 8 from positive reactors of intradermal test, 7 from Clonorchis infected, 9 from other parasitic diseases and 50 from apparently non-infected cases. By the result, the sensitivity of the test was 86% and the specificity was 100%. There were no cross reactions between Paragonimus antigen and other parastic infections. Specific IgG antibody test by micro-ELISA was concluded to be useful for mass screening of the presently ill paragonimiasis in the field.

A case of Lymphangiomatosis of the skeleton and soft tissue in a 23 years old woman is presented. Lymphangiomatosis are benign tumors formed of lymphatic vessel and like hemangiomatosis are probably best thought of as harmatomatous malformation. As term imply, the endothelial space in these lesions are lymph-rather than blood containing. Bone involvement are very rare condition that affect mainly the ilium and features a largely lytic pattern, consisting of tiny elliptical radiolucents slots. Treatment and Prognosis depend on the site and extent of involvement and progression. Although irradiation may be the treatment of choice, the lesions have not been usually successfully treated.

Atrial flutter, a common rhythm disturbance, was first described over 80 years ago. Despite extensive investigations, several important issues remain unresolved concerning its exact mechanism and management. Present therapeutic strategies often appear effective to prevent and terminate atrial flutter. However, controlled trial and definitive studies comparing the various treatment options are surprisingly scarce. Here we report on a study of 9 episodes of spontaneous atrial flutter(AF)(flutter wave cycle length 224+/-39 msec) treatedd by transesophageal atrial pacing(TAP) in 9 patients(7 men and 2 women; mean age 56.9 yrs). TAP was effective in 5 patients : sinus rhythm resumption was immediate in 3 patients and followed a short period of atrial fibrillation in 2 patients. TAP was unsuccessful in 4 patients. All the patients tolerated the procedure well. These data strongly support the immediate first choice use of TAP in AF therapy.

BACKGROUND: The catheter ablation usin radiofrequency(RF) energy in patients with atrioventricular nodal reentrant tachycardia(AVNRT) and atrioventricular reentrant tachycardia(AVRT) ahs been proved as a safe and effective nonpharmacologic therapeutic modality. The purpose of our study was to evaluate the success rate and complications of the initial experience and to determine the extent of myocardial damage of RF catheter ablation. METHODS: Electrophysiologic study was performed with the standard technique. Twenty five patinents(M:F=16:9, mean age:42 years old) underwent RF catheter ablation in St. May's Hospital from April to December in 1994. The RF generator in this study was RFG-3D model and catheters were 6F or 7F steerable catheters with 4mm kistal tip. In order to evaluate the extent of myocardial damage the WBC count, LDH, CK, and CK-MB fraction were checked before and after RF catheter ablation and the Tc99m myocardial scintigraphy was performed within 72 hours of the porcedure. RESULTS: Six of twenty five patients had AVNRT, in which the success rate of selective ablation of the slow pathway was 83.8%. Nineteen patients with AVRT had one accessory pathway. The ablation success rate of 14 accessory pathways in left free wall location was 85.7%, and that of 3 in left posteroseptal location was 66.6%. Two right sided accessory pathways were not ablated successfully. The level of CK-MB fraction after ablation was within normal limit. Only one case revealed grade 2 of hot spot in Tc99m myocardial scintigraphy. CONCLUSION: The RF catheter ablation in patients with AVNRT and AVRT is a safe and effective nonpharmacologic therapeutic modality. But right sided accessory pathways are more difficult to ablate than left sided accessory pathways, requiring more experiences and better technique. The extent of myocardial damage after RF catheter ablation reveals relatively minimal by cardiac enzyme study and Tc99mmyocardial scintigraphy.

BACKGROUND: Monophasic Action Potential(MAP) recording using contact electrode is very sensitive method to detect the ischemic changes of myocardium. The purpose of this study were to investigate changes of MAP during percutaneous transluminal coronary angioplasty(PTCA) and to evaluate through MAP whether or not a brief episode of ischemia influenced on subsequent ischemic episode during PTCA. Method: MAPs using endocardial contact electrode were recorded dbefore, during the fitst and second inflation and 3 min after PTCA in 7 patients undergoing PTCA. RESULTS: 1) MAP amplitude significantly decreased to 79.1+/-11.0% during the first inflation(p<0.05) and to 86.3+/-9.0% during the second inflation(p<0.05) and recovered to 92.7+/-3.7% at 3 min after PTCA. 2) MAP duration to 90% repolarization(MAPD 90) significantly decreased to 91.4+/-5.1% during the first inflation(p<0.05) and to 95.3+/-3.5% dudring second inflation(p<0.05) and recovered to 97.3+/-2.8% at 3 min after PTCA. 3) Double prodducts showed no significant difference between the first and second inflation. 4) The changes of MAP amplitude and MAP duration during the second inflation was significantly lower than that recorded during the first inflation. CONCLUSION: MAP recording using endocardial contact electode may be safe and very sensitive method to detect the ischemic changes of human endocardium and the lessened MAP changes during the second inflation supports the concept of preconditioning ischemia.

In literatures, most of the studies of severe hyponatremia during or following its treatment has been concentrated with special references to the rate of correction and its neurologic outcomes. But, there is relatively few ones analyzing the diverse clinical manifestations of neurologic symptorns or complications during the course of treating severe hyponatremia. We experienced a catastrophic course related to hyponatremia in a 51 year woman with severe rheumatoid arthritis, who underwent knee joint replacement, and this case revealed the initial transient neurologic recovery for 3 days by the initial rapid correction of hyponatremia, then followed by delayed deterioration of osmotic demyelination syndrome leading to locked-in syndrome. Reported cases with similar clinical course (biphasic course) in the world lituratures were reviewed with special interests in the initial maximum rate of correction of hyponatremia and radiologic findings. This review suggests that clinicians treating the patients with severe symptomatic hyponatremia should be aware of the possibility of delayed neurologic sequelae despite the recovery of neurologic status as well as the degree of hyponatremia in the early treatment course of hyponatremia.

BACKGROUND & METHODS: Approximately 10% of the essential hypertensive patient have overt proteinuria due to renal target organ damage, which indicates poor prognosis. Recently microalbuminuria has been prove to be a good early predictor for renal damage in patients with diabetes or hypertension. Some authors reported that near 40% of the essential hypertensives have microalbuminuria. To determinate prevalence of microalbuminuria in Korea essential hypertensives, 24-hr ambulatory blood pressure monitoring and radioimmunoassay to detect BP and UAER were performed after 4 weeks wash-out period in 137(78 hypertensive and 54 normotensive) consecutive cases. RESULTS: Among 78 hypertensives, overt proteinuria was seen in 8.97%(7/78). And prevalence of microalbuminuria were 29.4%(23/78) in hypertensives and 16.7%(9/54) in normotensives. Urine microalbumin excretion rate(UAER) was significantly correlated with mean arterial pressure(MAP) in total subjects(r=0.286, p=0.0012), but not in total hypertensives(r=0.135, p=NS) or in hypertensives with UAER(r=-0.098, p=NS).UAER of female hypertensives was increase than that of male hypertensives(13.17+/-16.28microg/min vs 22.87microg/min, p=0.027). CONCLUSION: Prevalence of microalbuminuria in Korean hypertensives was relatively lower then other reports. Overt proteinuria was noted in 8.97% of the hypertensives which is same prevalence as other countries. Moreover MAP was well correlated with UAER in total subjects. Further evaluation should be done to detect exact role of UAER in hypertensives as an early predictor for renal target organ damage.
