Retinal vein occlusion(RVO)is the second most common form of retinal vascular disease next to diabetic retinopathy. Systemic risk factors such as hypertension, diabetes, cardiovascular disease, blood dyscrasia and ocular risk factors such as short axial length, glaucoma, papilledema, thyroid ophthalmopathy have been shown to be associated with RVO. It is usually unilateral disease, and bilateral occurrene of RVO is relatively uncommon. CRVO rarely occurs bilaterally with a short interval between two eyes. Having experienced a case of bilateral CRVO within one month in a 75-year-old female with short axial length, primary open angle glaucoma, hypertension and hypercholesterolemia, we report this case with literature review.

PURPOSE: To report a case of Wegener's granulomatosis misdiagnosed as ocular tuberculosis. METHODS: A 65-year-old man who was treated with anti-tuberculosis medications as suspected pulmonary tuberculosis was referred from the department of internal medicine for visual loss over months. His initial visual acuity was counting fingers at 30 cm in the right eye and there was a chorioretinal scar involving the macula on fundus examination. At that time, we thought that the lesion was a tuberculosis-related chorioretinal scar and so he was treated with anti-tuberculosis medications. There was a recurrent bilateral anterior uveitis during three months from the initial visit. RESULTS: After 14 months, he was examined by otorhinolaryngologist due to a saddle nose deformity and Wegener's granulomatosis was diagnosed based on positive Cytoplasmic antineutrophil cytoplasmic antibody (c-ANCA) and nasal mucosal biopsy. At that time, ocular examination revealed the necrotizing scleritis in both eyes and orbital CT showed bony destruction of medial and inferior orbital wall without proptosis in both eyes. We had treated with oral cyclophosphamide and prednisone. CONCLUSIONS: We experienced a case of Wegener's granulomatosis with chorioretinal scar misdiagnosed as ocular tuberculosis. In conclusion, we should differentially diagnose Wegener's granulomatosis from suspected ocular tuberculosis.

PURPOSE: To report a case of Klebsiella pneumoniae endogenous endophthalmitis secondary to renal or urinary tract infection such as emphysematous pyelonephritis. METHODS: A-56-year-old woman with diabetes mellitus and emphysematous pyelonephritis was reterred to us in consultation for visual loss in her right eye for 5 days. Ophthalmologic evaluation and intervention were performed. RESULTS: Culture revealed Klebsiella pneumoniae from vitreous tap of the right eye. Systemic antibiotics, intravitreous antibiotics injection and vitrectomy were performed, but the eye showed progressive worsening to phthisis. CONCLUSIONS: A high index of suspicion of Klebsiella pneumoniae endogenous endophthalmitis must be carried in patients with renal or urinary tract infection such as emphysematous pyelonephritis as well as hepatobiliary disease such as pyogenic liver abscess.

BACKGROUND: The two most commonly used drugs as a stressor during wtress echocardiography are dipyridamole and dobutamine. The purpose of this study was to compare diagnostic accuracies of dipyridamole and dobutamine stress echocardiography for fixed coronary artery disease and evaluate complications related to the two agents in the same patients. METHODS: 30(M : 5=19 : 11, age=56+/-8.8yr) consecutive patients without history of previous myocardial infarction underwent coronary angiography, dipyridamole and dobutamine stress echocardiography in random order. Dipyridamole was infused up to 0.84mg/Kg for 10 minutes during clinical, ECG and echocardiographic montioring. Dobutamine was infused in dose increments from 5 to 40microg/Kg/min under the same condition. Positive criteria for myocardial ischemia by echocardiography was now regional wall mation abnormatity or worsening of regional wall motion after stress. Significant coronary disease was defined as more than 70% stenosis by coronary angiography. RESULTS: The sensitivity and specificity of both stress echocardiography were same, 82% and 92% respectively. In a single vessel disease the sensitivity of dipyridamole echocardiography was 75% and dobutamine echocardiography was 83% without statistical difference. The correlation of ischemic free time during both stress test was 0.375. During dipyridamole infusion no test was prematurely terminated because of side effects, but 3 patients(10%) developed severe hypertension and ventricular arrytricular arrythmia during dobutamine infusion and test was terminated. CONCLUSION: Thus, by this prospective direct comparison of both stress test, dipyridamole and dobutamine stress echocardiography have similar diagnostic accuracies for the detection of coronary artery disease. But during dobutamine infusion, careful monitoring for hemodynamic changes arrythmia is required for possible serious complications.

BACKGROUND: The presence of diastolic mitral regurgitation has been described in patients with complete atrioventricular(AV) block, aortic valve regurgitation, hypertrophic and restrictive cardiomyopathy, and in patients with long diastolic filling period in atrial fibrillation. However, because of rare incidence and difficulty in making diagnosis of this phenomenon, the frequency and hemodynamic effects of diastolic AV valve regurgitation(DAVVR) and relationship of electrocardiographic(ECG) parameters with DAVVR in patients with complete heart block have not been reported in Korea. METHODS: To evaluate the frequency, hemodynamic effects of DAVVR and relation of ECG parameters with DAVVR in patients with complete AV block, we studied 14 consecutive patients with complete AV block by means of two dimensional and Doppper echocardiography. RESULTS: The DAVVR was observed in all cases of complete AV block except 3 cases on temporary pacemaker. The peak velocy of diastolic mitral and tricuspid valve regurgitaton were 105+/-23cm/sec and 98+/-30cm/sec, respectively. The peak and mean pressure gradient of diastolic mitral regurgitation were 4.7+/-1.7mmHg and 3.1+/-1.5mmHg respectively, and the peak and mean pressure gradient of diastolic tricuspid regurgitation were 4.1+/-2.6mmHg and 2.7+/-2.1mmHg, respectively. There was regular interval between p-wave of ECG and onset of diastolic AV valve regurgitation, which was 215+/-12msec, Diastolic AV valve regurgitation disappeared immediately after recovery of complete AV block to sinus rhythm or insertion of DDD-type permanent pacemaker in all cases. CONCLUSION: In Conclusion, the DAVVR was observed in all cases of complete AV block except cases on temporary pacemaker insertion and its hemodynamic effect was mild. There was regular interval between p-wave of ECG and the onset of diastolic AV valve regurgitation.

BACKGROUND: Left ventricular dilatation after acute myocardial infarction is caused by infarct expansion and compensatory dilatation of noninfarct area. This study was done to investigate the contributory topographical change of left ventricle to left ventricular dilatation after acute myocardial infarction. METHODS: 24 first acute myocardial infarction was studied with 2-dimensional echocardiography serielly. First study was done at 7days and second study was done 9 months after an infarction attack. Left ventricular volume was measured by Simpson's method in end-diastolic frame and change of end diastolic left ventricular surface area was measured in apical 4 chamber view. Left ventricular surface area was devided by ischemic(noncontraction) and nonischemic(contracting) area by connecting central point of long axis of left ventricle and the junction of dyssynergic motion and normal motion point in outer rim of left ventricle in end diastolic frame of apical 4 chamber view. RESULTS: Mean left ventricular end-diastolic volume at entry was 114+/-23ml and increased to 121+/-27ml at 9 months after acute myocardial infarction in whole group(p=0.02). In a subgroup of anterior infarction, the left ventricular surface area was increaed in 9 cases with increared left ventricular volume(34.8+/-5.1cm2 to 36.4+/-4.1cm2, p=0.02) and ischemic surface area did not change in these group. In 7 patients without increase in left ventricular volume, the left ventricular surface area did not change and ischemic surface area decreased(9.4+/-4cm2 to 8+/-3.2cm2, p=0.03) at 9 months. CONCLUSION: Thus the increase in left ventricular end-diastolic volume between 13 days and 9 months after acute myocardial infarction is considered to be a consequence of noninfarct ventricular area dilatation.

BACKGROUND: Celiprolol is a new generation beta-adrenoreceptor blocking agent with intrinsic sympathomimetic activity characterized by selective blockade of beta1 receptors and partial agonist activity at beta2 receptors. This study was designed to investigate the antihypertensive efficacy and safety of celiprolol in patients with essential hypertension. METHODS: The study subjects consisted of 36 patients(mean age : 55 years, 11 males, 25 females). Celiprolol was administered orally in a aily dose of 200-800mg once or two divided dose for 10 weeks after the admimstration of placebo for 2 weeks. RESULTS: Blood pressure was significantly reduced from 171+/-19/106.8mmHg to 153+/-20/92+/-12mmHg(p<0.01) after 2 week of therapy and this effect was maintained throughout the study periods. The efficacy rates were total 94%(marked improve : 53%, moderate improve : 22%, mild improve : 19%). The cumulative efficacy rate was 72% at 200mg/day, 91% at 400mg/day, and 94% at 800mg/day. Heart rate did not change throughout 10 weeks. There were no significant change in hematologic and blood chemistry variables. During the period of medication, headache developed in 3 cases(8%) and each of dry cough, dyspnea, epigastric pain and diarrhea and facial flushing developed in 1 case(2.8%) but they were tolerable. CONCLUSIONS: This results suggest that celiprolol is effective and safe drug in the treament of patients with essential hypertension.

BACKGROUND: QT dispersion(QTD : QTmax-QTmin) or JT dispersion(JTD:JTmax-JT-min)in 12 leads ECG has been known to reflect regional variations in ventricular repolarization and has been reported to bel one of the marker of regional myocardial ischemia. To evaluate the significance of QTD or JTD of exercise ECG in diagnosis of coronary artery disease, we studied 106 patients(mean age, 56.9 years old, male 63) who were referred for the evaluation of chest pain on exertion. METHOD: Treadmill exercise stress test with modified Bruce protocol and coronary angiography were performed in 106 patients with chest pain on exertion. ST-segment depression by >1.0 mm 0.08 second after J-point during or after exercise in exercise test and >50% stanosis of epicardial artery in coronary angiogram were defined as positive. Of 106 patients, 41 had positive exercise ECG and positive coronary angiogram(true positive, TP), 20 had positive exercise ECG and negative coronary angiogram(false positive, FT), 20 had negative exercise ECG and positive coronary angiogram(faalse negative, FN), and 23 had negative exercise ECG and negative coronary angiogram(true negative, Tn). QT and JT interval in 12 leads were measured at baseline and peakexercise and were corrected for heart rate using Bazett's formula. QTD and JTD were measured by calculation the difference between the maximum QT and mininum QT and that between maximum JT and minumum JT. RESULTS: QTD at baseline for TP(72.8ms)was prolonged compared to Tn(52.2ms,P<0.01), but was not different from that for FT(70.2 ms). At peak exercise, QTD for TP(81.3 msec) was significantly prolonged(p<0.01), while QTD for FP(71.2 msec) was not different from that for TN(56.8 msec). JTD at baseline(78.4 msec) and at peak exercise(88.2 msec) for TP were significantly prolonged compared to those for TN(55.2msec and 55.1msec p<0.01,p<0.01, respectively), but those for FP were not porlonged(77.0msec and 79.0msec, respectively). QTD and JTD at peak exercise were more markedly prolonged in patients with sever stenosis of coronary artery(p=0.053 and p<0.05, repectively) and multivessels diseases(p<0.01, 0<0.05) than those with less severe disease and single vessel disease. Patients with left anterior descending artery lesion had greater QTD and JTD at peak exercise than those with other vessels lesion(p<0.01). In addition to standard criteria with ST segment displacement in exercise EGC, inclusion of exercise induced QTD of more than 60msec increased the sensitivity of exercise ECG from 66.7% to 83.3%, and JTD of more than 70msec increased the specificity from 52% to 76.0%. CONCLUSION: Measurement of QT dispersion and JT dispersion of exercise ECG may be useful method to identify the severity of coronary artery disease and to improve diagnostic accuracy of exercise ECG in coronary artery disease.

BACKGROUND: Delapril, a recently developed nonsulfhydry(SH) angiotensin converting enzyme inhibitor, was known to have more prolonged duration of action. In order to investigate the efficacy and safety of delapril, patients with essential hypertension were studied. METHODS: The study subject consisted of 37 patients(mean age : 50.4 years, 15 male, 22 female). Because 4 of 37 patients dropped out due to side effects of delapril, the antihypertensive efficacy was evaluated in the remaining 33 patients. Delapril was administered orally in a daily dose of 30-120mg in two divided doses for 10 weeks after the administration of a placebo for 2 weeks. RESULTS: Delapril decreased systolic blood pressure significantly from a baseline value of 162.4+/-18.8mmHg to 142.9+/-20.9mmHg(p<0.01) and diastolic blood pressure from 103.2+/-5.0mmHg to 92.8+/-10.4mmHg(p<0.01) after 2 weeks of therapy, and maintained this effect throughout the study period. The efficacy rates were 72% for systolic pressure, 75% for diastolic pressure. The cumulative efficacy rate was 48% at 30mg/day, 66% at 60mg/day, and 73% at 120mg/day. Heart rate did not change until after 8 weeks, when they modestly decreased(p<0.05), through the 10th week(NS). Side effects were noticed in 12 out of 37 cases(32.4%). The main symptoms included dry cough(7 cases, 18.9%), headache(2 cases, 5.4%), dizziness(1 case, 2.7%), dry mouth(1 case, 2.7%) and angioedema(1 case, 2.7%). Six of the 7cases of dry cough were in women, and 3 caes discontinued the drug due to intractable cough. Angioedema in the oropharynx occurred in 1 patient and caused severe dyspnea which was relieved by the discontinuation of the medication. There was no significant change in CBC and biochemical variables. CONCLUSIONS: A daily dose of delapril in two divided doses is effective in decreasing blood pressure in patients with essential hypertension, and safe when an awareness of possible side effects is taken into account.

BACKGROUND: The restoration of anterograde flow in the infarct-related artery(IRA) may improve electrophysiological consequences and survival. Patients with occluded IRA are more likely than those with patent IRA to have late potentials on signal-averaged electrocardiogram(SAEKG). The natural history of late potentials in the acute phase after AMI was reported to vary in recent studies and requires further investigation. Therefore, we investigated 1) whether parameters of SAEKG and incidence of late potentials are changed in 2 weeks after AMI, and 2) whether the status of IRA, ejection fraction, ventricular premature beats(VPB) on Holter and the use of thrombolytic agent can influence the developement of late potentials. METHOD: SAEKGs were performed in 40 patients with acute myocardial infarction(AMI, mean age : 56.6yr) and 20 normal controls(mean age : 53.0yr). SAEKGs were recorded first in 48 hours and then 2 weeks after AMI. Late potential were considered to be positive if two of the three following criteria were identified : 1) duration of filtered QRS complex>118ms, 2) duration of HFLA signal>40 ms, and 3) RMS voltage<20microV. RESULT: 1) The duration of filtered QRS complex and HFLA signal in patients with AMI in 48 hours and 2 weeks were longer than in the controls(p<0.01, p<0.05. respectively), and the RMS voltage in only 2 weeks was lower than in the controls(p<0.05). 2) There was no significant difference in the 3 parameters of SAEKG between 48 hours and 2 weeks after AMI, but the incidence of late potentials increased from 35%(14/40) to 42.5%(17/40). Of the 26 patients with a normal initial SAEKG, 3(11.5%) had late potentials in 2 weeks, whereas none of the patients with positive late potentials on initial SAEKG was normalized in 2 weeks. 3) The ejection fraction, the degree of VPB on the Holter EKG and the history of thrombolyic therapy in patients whose late potentials were positive were not different from those in patients with normal SAEKG. 4) In the 3 parameters of SAEKG, RMS voltage in patients with occluded IRA was significantly lower than in those with open IRA(p<0.05), and the incidence of late potentials were higher in the patients with occluded IRA(75%) than in those with open IRA(28.6%)(p<0.05). CONCLUSION: The incidence of late potentials on SAEKG after AMI was modestly increased in 2 weeks, but the development of late potentials was not influenced by the degree of frequently in patients with occluded IRA. These findings may indicate that the development of late potential after AMI tends to increase even in 2 weeks, and that the occlusion in IRA may unfavorably alter the electrophysiological state identified by SAEKG.
