Regional left ventricular dysfunction is common in patients with coronary artery disease and accurate analysis of regional dysfunction is of particular interest. For the quantitative assessment of regional dysfunction, we measured regional ejection fraction by radial sector division method in 19 patients with acute myocardial infarction and 13 normal controls who had multigated blood pool scan. And two independent observer analyzed regional wall motion using 5 point grading system in 18 patients undergoing radionuclide ventricular cineangiography. The results obtained were as follows : 1) Regional wall motion scores for the gated blood pool study agreed completely in 72 of 108 segments (66.7%) and agreed within 1 grade in 88 of 108 segments(81.5%) and agreement rate is lowest in the septal area. 2) Global left ventricular ejection fraction was 63.2+/-4.2% in normal controls, 36.6+/-6.8% in extensive anterior wall infarction group and 52.6+/-9.7% in inferior wall infarction group. The value of extensive anterior wall infarction group was significantly lower than that of inferior wall infarction group(p<0.005). 3) Regional left ventricular ejection fraction by radial sector division method in normal control group were as follows : area 1 ; 56.5+/-6.7%, area 2 : 77.9+/-4.8%, area 3 ;84.3+/-5.5%, area 4 : 76.8+/-6.6%, area 5 ; 84.7+/-7.6%, area 6 ; 85.9+/-11.2%, area 7 ; 75.5+/-12.3%, area 8 ; 74.9+/-14.0%, area 9 ; 75.5+/-8.8%, area 10 ; 54.2+/-11.0%, 11 ; 34.5+/-16.3, area 12 ; 37.1+/-18.0%. 4) Mean regional ejection fraction in 7 patients with anterior wall infarction showed significantly lower values in area 4 to area 8, and in area 2 to area 5 in case of inferior wall infarction group. 5) We thought that regional ejection fraction obtained by radial sector division method is valuable index for the management and evaluation of patients with coronary artery disease.

Liquid tissue adheisve, Histoacryl (n-butyl-2-cyanoacrylate) has been used for the treatment of gastric variceal bleeding. The techniques are as follows: 0.5cc Histoacryl mixed with Lipiodol per each injection are used. 3 to 4 injections are usually required for large variceal convolutes under the fluoroscopic visualization after the injection of Histoacryl. Complications of sclerotherapy with Histoacryl are bleeding, perforation, stenosis and embolism depending on the concentration and amount used, as well as the intensity of the treatment. Here we describe a case report developing portal and splenic vein thrombosis as a side effect after Histoacryl injection therapy for the treatment of gastric varix bleeding, A 59-year-old male patient with liver cirrhosis was admitted due to acute gastric varix bleeding. The control of gastrie variceal bleeding was achieved by several injections of 0.7c mixture of 0.5cc histoacryl and 0,8cc Lipiodol. However, simple X-ray and ultrasonography revealed the elements of Histoacryl-lipiodol mixture in the portal and splenic vein.

A statistical study was done on arrhythmia of the aged who were older than 60 during the period 1963~1972 at Seoul national University Hospital. This study included 6,511 patients among 40,000 total patients. The results were as follows. 1) Arrhythmias were observed among 3,058 patients(46.97%). Sinus irregularitis were the most frequent arrhythmia. 2) Except sinus irregularities premature beat (38.3%), atrial fibrillation (16.1%), bundle branch block (10.5%), atriovenricular block (10.5%), atrioventricular escape beat (5.1%), atrioventricular junctional rhythm (4.9%), wandering pacemaker(4.0%) and paroxysmal tachycardia(2.5%) were frequent arrhythmias. 3) Cardiovascular disease was major underlying disease. In cardiovascular disease group, the incidence of arrhythmia was 51.15% which was three times as high as non-cardiovascular and normal group. 4) Most arrhythmias were more frequently observed among the aged except bundle branch block and ventricular paroxysmal tachycardia. 5) The incidence of arrhythmia was similar among the aged except pre-excitation syndrome which was predisposed to woman. 6) Arrhythmia was most frequently observed in coronary heart disease. 7) Among sinus irregularities, simus bradycardia was more frequent in the aged. 8) There were no significant differences in frequency of arrhythmia between non-cardiovascular disease group patients and normal group.

PURPOSE: Few epidemiologic studies have investigated aggressive periodontitis in Koreans, but such studies of disease prevalence and other clinical characteristics would be invaluable in providing proper treatment. The aim of this study was to assess the prevalence of aggressive periodontitis and to measure the extent of associated periodontal breakdown. METHODS: The study population consisted of 1,692 patients who visited the Department of Periodontology, Wonkwang Daejeon Dental Hospital from January to December, 2010. Clinical parameters (probing depth, gingival recession, periodontal attachment loss) were measured by a single examiner, and radiographic examination was performed at the baseline. RESULTS: Twenty-eight (1.65%) patients showed clinical features of aggressive periodontitis, of which 27 patients exhibited the generalized form, and 1 exhibited the localized form. There was no significant difference between the percentage of male and female patients. The probing pocket depth of the maxillary first molar was deeper than that of the other teeth and gingival recession was also the most serious at the maxillary first molar. The periodontal attachment loss was the highest at the maxillary first molar. The average number of missing teeth was 1.29 per subject. Loss of the second molar was prominent. CONCLUSIONS: Within the limitations of this study, the periodontal breakdown evaluated by attachment loss was found to be most severe at the first molars of aggressive periodontitis patients. However, further large scale multicenter studies are necessary to access more precise data, including prevalence.

OBJECTIVE: Closure of a low transverse cesarean incision with one layer and two layer, we compared operative time, hemostasis, blood loss and postoperative sonohysteroperitoneographic findings. Study design: At our hospital 103 women were randomized to closure of a low transverse cesarean incision with either one continuous layer of a locking No. 1 chromic suture or two continuous of No. 1 chromic suture with the first layer locked between Mar. 1, 1998 and Dec. 31, 1998. After three months later, sonhysteroperitoneography was taken and then we evaluated uterus indirectly. RESULTS: A one layer closure required less operative time, 16 versus 20.8 minutes (p<0.01), less hemoglobin change, 0.44 versus 1.3 (p<0.01) and less suture materials (p<0.01). But postoperative follow up sonohysteroperitoneography, a one layer closure shows slightly thinning of isthmic layer of myometrium, two layer closure shows more adhesional band and both are similar other findings. CONCLUSION: A one layer does not significantly affect the clinical course than traditional two layer closure. So we recommended a one layer closure when its use is anatomically feasible.

Pacemaker twiddler's syndrome is reported as a very rare complication of permanent pacemaker implantation. There was a recent report suggesting that the incidence of pacemaker twiddler's syndrome increase recently presumably as a result of the implantation of thinner and smaller pacemaker system than before. We experienced a case of pacemaker twiddler's syndrome complicated 3 times with the conventional method of implantation or replacement during 14 months after the first implantation(Optims MP 158C and Pacing lead 400, Telectronic)on June 13th 1987. This case was an 18 year-old high school girl who had suffered frequent syncope for 2 years and extertionl dyspnea for 5 years due to congenital complete heart block, of which block site was proved to be AV nodal by His bundle electrogram. Pacemaker twiddler's syndrome developed 3 times;firstly 6 weeks after the first implantation in the right subclavicular fossa, secondly 10 weeks after the replacement of the twisted pacing lead, thirdly 10 months after the change of implantation site to the left subcalvicular fossa with the replacement of the twisted and fractured lead. Finally, the pacemaker generator was anchored to the clavicular periostium and pectoralis fascia at several points by using Dacron pouch.

As the first nationwide Korean prospective multicenter data collection registry, the Korea Acute Myocardial Infarction Registry (KAMIR) launched in November 2005. Through a number of innovative approaches, KAMIR suggested new horizons about acute myocardial infarction (AMI) which contains unique features of Asian patients from baseline characteristics to treatment strategy. Obesity paradox was existed in Korean AMI patients, whereas no gender differences among them. KAMIR score suggested new risk stratifying method with increased convenience and an enhanced accuracy for the prediction of adverse outcomes. Standard loading dose of clopidogrel was enough for Asian AMI patients. Triple antiplatelet therapy with aspirin, clopidogrel and cilostazol could improve clinical outcomes than dual antiplatelet therapy with aspirin and clopidogrel. Statin improved clinical outcomes even in AMI patients with very low LDL-C levels. The rate of percutaneous coronary intervention was higher and door-to-balloon time was shorter than the previous reports. Zotarolimus eluting stents as the 2nd generation drug-eluting stent (DES) was not superior to the 1st generation DES, in contrast to the western AMI studies. KAMIR made a cornerstone in the study of Korean AMI and expected to be new standards of care for AMI with the renewal of KAMIR design to overcome its pitfalls.

The only clinically avilable levo-isomer type of beta-recepter blocker is penbutolol sulfate, and it is already accepted as one of beta-receptor blockers for initial antihypertensive drug therapy according to the report of 1988 Joint National Committee on Detection, Evaluation, and Tratment of High Blood Pressure. To evaluate the antihypertensive efficacy, effect on the quqlity of life, and side effects of penbutolol recently introduced into Korea, penbutolol was administered to 29 essential hypertensive(mild 9, moderate10, and severe 10) patients for 12 weeks or longer. The result of the clinical analysis are as follows; 1) The mean age was 50.0+/-10.9(M+/-SD), and the sex distribution between male and female was16:13. 2) The blood pressure lowering effects of penbutolol as a monotherapy were marked in 16, moderate in 6, and insignificant in 2 cases. The systolic blood pressure was significantly decreased from 179.1+/-20.2 to 135.4+/-16.5mmHg(P<0.005), and the diastolic blood pressure from 112.6+/-13.5 to 84.0+/-11.9mmHg(P<0.005)after 12 weeks' penbutolol therapy. 3) The heart rate was significantly decreased from70.3+/-13.3 to 65.5+/-9.1 per minute(P<0.05). 4) The quality of life was improved markely in 5(17.2%) and slightly in 8 cases(29.6%). 5) There were no significant laboratory changes after 12 weeks' penbutolol therapy. 6) Two out of three cases with non-specific ST segment and T wave changes in EKG and two out of 9 cases with EKG were normalized, 2 cases of LAH with strain were improved. 7) The side effects of penbutolol were dizziness in 4, sexual dysfunction in 2, and skin rash in 1 case. 8) Final multifarious assessment of penbutolol therapy showed that it was very useful in 11(37.9%), useful in 4(13.8%) and slightly useful in 7 cases(24.1%). These reult suggest that penbutolol is a first-line antihypertensive agent with an effective antihypertensive action, improving quality of life, with no significant laboratory changes and few side effects.

Swallowing is a rare cause of neurally mediated syncope. The mechanism of swallow syncope that contributes to hypotension, bradycardia, or to both is complex. A 59-year-old man had experienced a recurrent loss of consciousness during swallowing of carbonated beverages or sticky foods. Another 59-year-old man had complained of intermittent syncope just after eating foods. These two patients had no significant structural or functional abnormalities in the esophagus or heart. Both cases showed bradycardia when the lower esophagus was stretched by balloon inflation. The activation of mechanoreceptors in the lower esophagus can be regarded as an initiating factor of these cardioinhibitions. The patients were treated with permanent pacemaker implantation and instructed to change eating habits, respectively.

There is no doubt that the diastolic dysfunction of the left ventricular plays an important role in the pathophysiogy of clinical heart faliure in some patients, if not all, and that many hypertensive subjects manifest diastolic dysfunction of the left ventricle in its early hypertensive stage. But yet, it is not clear which paramenter is most sensitive and/or specific, and consistent with pathophysiologic states. In order to have an insight into the problems, 30 hypertensives and 30 normotensive subjects were studied by phonocardiogram and pulsed Doppler echocardiogram at the left ventricular inflow and then isovolumic relaxation time(A2D time), early diastolic deceleration time(EDDT), early diastolic deceleration rate(EDDR), late diastolic time(LDT), E.A velocity ratio[E/A(v)]and E/A area ratioA(a)] were measured and calculated. And the values of each parameters of different groups were subgrouped according to the severity of the hypertension(Group A:mild, B:moderate and C:severe hypertension) and according to the LV mass(Group D:LVMI<125g/m2, GroupE:LVMI> or =125g/m2) were compared with those of the normal control subjects and also between each subgroups. The results were as follows : 1) In the 30 normotensive subjects, A2D time was averaged out 60.8+/-12.5msec, E/A(v) 1.55+/-0.59, E/A(a) 2.61+/-1.35, EDDT 1.35+/-37.8msec, EDDR8.3+/-4, 6m/sec2 and LDT 151+/-42.2msec. 2) In group A, A2D time was significantly prolonoged(82.5+/-26.0msec, p<0.005) and E/A(v) markedly decreased(1.12+/-0.40, p<0.05) compared to those of normotensive group. 3) In group B, A2D time was significantly prolonged(78+/-20.8msec, p<0.005), and E/A(v)(0.92+/-0.42, p<0.005) and EDDR(4.9+/-1.5m/sec2, p<0.05) were significantly decreased compared to those of the control group. 4) In group C, A2D and EDDT were increased(p<0.005, p<0.05 respectively) while E/A(v) and EDDR decreased(p<0.01, p<0.05 respedtively), while E/A(v) and EDDR decreased(p<0.01, p<0.005 respectively). 5) In group D, A2>D and EDDT were significantly prolonged(p<0.005), while E/A(v), E/A(a) and EDDR wer significantly decreased(p<0.005, p<0.05 respectively). 6) In group E, A2D and EDDT were significantly increased(p<0.005, p<0.05 respectively), while E/A(v) and EDDR significantly decreased(p<0.005, p<0.05 respectively). Above results suggest that diastolic function of the left ventricle can be deteriorated in the hypertensive subjects before systolic dysfunction is apparent even in the mild hypertensives and in the patients devoid of hypertensive hypertrophy of the left ventricle.
