We observed the motion of left ventricular posterior wall aortic root posterior wall in 20 normal persons and 20 patients with left ventricular hypertrophy during the period from March 1985 to Agust 1985. The results were as followings; 1) The percentage of rapid filling time to one cycle of heart beat obtained from the ventriculat posterior wall motion was significantly prolonged in patients with left ventricular hypertrophy(24.1+/-5.44%) than in normal persons(13.5+/-3.69%)(p<0.05) and that of slow filling time was significantly shortend in patients with left ventricular hypertrophy(27.4+/-6.10%) than in normal persons(38.7+/-9.06%)(P<0.005). 2) The rapid filling slop obtained from left ventricular postrior wall motion was significantly reduced in patients with left ventricular hypertrophy(44.0+/-12.45mm/sec)than in normal persons(91.7+/-53.16mm/sec)(P>0.005) but the slow were not signigficantly different between the two groups. 3) The left artial emptying index calculated from the aortic root posterior wall motion was significantly lower in patients with left ventricular hypertrophy(0.6+/-0.18) than in normal persons(1.1+/-0.26)(P<0.005).

To investigate frequency of painful and/or silent myocardial ischemia(SMI) determined by ECG ST-segment depression(more than 1.0mm depression for 0.08 second after J point over 60 seconds) during unrestricted daily activities, 24-hour dynamic ECG was performed in 19 patients(11 males, 8 females) with chronic stable angina pectoris, aged 57.4 years(44 to 73 years). During 456 hours of recording, there were 154 episodes of SMI. Of these, 139 episodes(90.3%) were silent and 15 episodes(9.7%) accompaned chest pain. The higher incidence of SMI than previously published data is probably influenced by 1 patient who disclosed 56 episodes (excluding this, SMI 84.7%). Sixty one percent of episodes of SMI occurred during light activities such as slow walk, hand labor, eating or at rest(sitting at ease), smoking and sleep, and 39% during more strenuous activites such as walk, climbing stairs and physical exercise. In contrast, most of the painful myocardial ischemia(PMI) developed during climbing stairs, walk and physical exercise. Heart rate during episodes of SMI varied ranging from 85.2+/-13.7/min at rest to 115.5+/-19.2/ min druing climbing stairs. Mean ST-segment depressions during episodes of SMI and PMI were 2.0(1.0-4.0)mm and 2.6(1.2-7.0)mm, respectively, in 6 patients who disclosed both SMI and PMI on 24-hour ECG recordings. However, frequency of ischemic episodes was higher(9.0 vs 2.5/day) and duration was longer(13.8min vs 3.0min) in SMI. These findings indicate that transient SMI in patients with chronic stable angina pectoris occurs more frequently than painful myocardial ischemia. In addition, SMI develops during activities that increase heart rate(increased O2 demand) as well as during activites that do not increase heart rate(decreased O2 supply). Therefore, both O2 demand and supply mechanisms may be involved in the pathogenesis of transient SMI in Patients with chronic stable angina pectoris.

Epidermolytic keratosis palmaris is a rare disease which shows clinical findings of Unna Thost keratoderma and histopathologic of epidermolytic hyperkeratosis. We report herein a case of epidermolytic keratosis palmaris et plantaris in a 16-month-old female baby. Light microscopy shows marked hyperkeratosis, large irregular keratohyalin granules, and large clear spaces in the granular and upper spinous layers. Eletron microscopic findings shows that the clear spaces are areas of cytoplasm filled with a fibrillar material and cellular organelles. Abnormal clumping of tonofilament and keratohyalin is also present.

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.

Aortic root diameter by two dimensional and M-mode echocardiography in predicting prosthetic aortic valve size preoperatively was measured in 10 adult patients undergoing aortic valve replacement. Correlation of aortic root diameter measured by two dimensional echocardiography and actual prosthetic valve size implanted by aortic valve replacement was excellent. Correlation coefficient was statistically significant (r=0.91, P<0.001). Correlation of aortic root diameter measured by M-mode echocardiography and actual prosthetic valve size was also excellent. Correlation coefficient was statistically significant (r=0.86, P<0.001). This study demonstrates that aortic root diameter by two dimensional and M-mode echocardiography can accurately predict prosthetic aortic valve size in patient undergoing aortic valve replacement.

Sertoli-Leydig cell tumors of the ovary are rare, accounting for no more than 0.5% of all ovarian neoplasms. These tumors occur predominantly in women 10 to 30 years of age. Heterologous elements are found in over 20% of the moderately and poorly differentiated Sertoli- Leydig cell tumors. The most common element is gastrointestinal mucin-secreting epithelium, found in approximately 20% of all cases. Approximately 4% of Sertoli-Leydig cell tumors contain immature skeletal muscle and/or cartilaginous elements. The origin of these neoplasms is regarded as neometaplasia of the mesodermal neoplastic element. While the degree of differentiation of Sertoli-Leydig cell tumors is probably of greater importance in determining prognosis than the presence of heterologous components, recent evidence does point to an unfavorable effect on clinical outcome when heterologous mesenchymal components such as cartilage and striated muscle are present. We experienced two cases of ovarian heterologous Sertoli-Leydig cell tumors with gastrointestinal type epithelium and striated skeletal muscle in 20 and 21 year-old females, respectively. One case involved a patient who had complained of amenorrhea for 3 years while the other case involved a patient who had complained of left lower abdominal tenderness and amenorrhea for one and one half years. It was determined by ultrasonography of the pelvis that the two patients suffered from right and left ovarian masses. Both patients underwent adnexectomy. These tumors were large with partly solid and partly cystic areas. Based on light microscopic examination one case was classified as an intermediate Sertoli-Leydig cell tumor with heterologous gastrointestinal type epithelium, while the other case was classified as a poorly differentiated Sertoli-Leydig cell tumor with heterologous striated skeletal muscle.

To assess the efficacy of amiodarone on chronic atral fibrillation(AF) and to evaluate the relation between the ability to convert AF to sinus rhythm (SR) with amiodarone therapy and left atrial(LA) size and atrial fibrillatory wave forms, 22 patients with AF, aged 40 to 60 years(mean 47.5 years), were studied. Nine patients(40.9%) had mitral valvaular heart disease, 6(27.3%) hypertension, 5(18.2%) lone AF and 2 (9.1%) cadiomyopathy. Amiodarone therapy with either 600mg for 1 week, 200mg for 4 weeks in 5 consecutive patients, or 800mg for 1 week, 400mg for 4 weeks and 200mg for 6 weeks in 17 patients, converted AF to SR in 9(40.9%) patients 3 to 6 weeks after amiodarone was started on. In either group, patients who achieved conversion had smaller LA size(mean 43.7mm) than those who failed conversion(mean50.2mm)(P<0.05). Those who had LA size less than 45mm achieved conversion of AF to SR in 70%, comparing to 16.7% in patients with LA size more than 46mm(P<0.05). Among patients who achieved conversion, LA size was less than 46mm in 77.8% comparing to 23.1% in patients who failed conversion on Amiodarone. Those with coarse AF(46.2mm), althogh the difference was not significant statistically. There was no converstion in patients with LA size greater then 58mm and in patients with coarse AF who concomittantly had MVD. These findings suggest that the efficacy of amiodarone was related to LA size, and to the atrial fibrillation wave form in patients with mitral valvular heart disease.
