We experienced a case of pedunculated left atrial primary fibrosarcoma, which obstructed the mitral orifice and produced symptoms and manifestations of mitral stenosis clinically. There was no evidence of metastasis to adjacent tissue or distant organs. It was treated by open heart surgery.

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).

Great strides has been made in the past 20 years in the treatment of scoliosis. Treatment before scoliosis becomes severe eliminates the need for extensive surgery. Early detection of scoliosis by school screening has proven to be valuable for early diagnosis and prevention of severe deformities. Authors screened 5,256 middle and high school students in Seoul, who were chosen arbitrarily, to determine the incidence rates of scoliosis, and following results were obtained. 1. Scoliosis was diagnosed on a combination of at least one positive physical sign and a lateral curvature more than 5 degrees on an antero-posterior standing X-ray. 2. The overall incidence of scoliosis was 4.68% (Male 0.74%, Female 6.43%). 3. Idiopathic scoliosis was found in 238 students, congenital scoliosis in 5, and paralytic scoliosis in 3. 4. The most common pattern of curvature was thoracic curve. 5. In the single curve right to left ratio was 2.1, but 8.4 in the upper curve of double curve. 6. Close observations were required for all the 246 students and treatment was required in 14 students who had more than 20 degrees, 9 students for Milwaukee brace, and 5 students for surgical correction.

Testicular microlithiasis (TM) is an uncommon abnormality in which concentric laminated bodies are scattered throughout the testis within seminiferous tubules. The sonographic appearance of TM is characteristic. In a retrospective analysis of 281 testicular sonograms, TM were found in 7 cases (2.5%). The presence of TM was associated with the presence of acute epididymitis (n=3), varicocele (n =l), hydrocele (n =l), testicular tumor (n =l), and cryptorchidism (n =l). The pathogenesis of TM is still poorly understood and its clinical relevance is unclear. However, because TM may be associated with testicular tumor, we advocate careful evaluation and follow up of the testes when this abnormality is detected.

Myoglobin has been shown to be elevated in the serum after myocardial infarction. Myoglobin is one of the first to appear in the serum and its quantification may thus be used in the diagnosis of the early phase of acute myocardial infarction. The purpose of this study was to clarify the time course of myoglobin elevation in the early phase of acute myocardial infarction. We compared this with the time course of serum CPK and obtained following results: 1) Serum myoglobin becomes significantly elevated at 4 hours following onset of chest pain and apears earlier than CPK. 2) Serum myoglobin time curve peaks at 8 hours, whereas the CPK time surve peaks at 16 hours following onset of chest pain. 3) Mearsurement of serum myoglobin in the early phase of acute myocardial infarction can serve as valuable aid in diagnosis of myocardial infarction with other findings.

BACKGROUND: Circardian variation in the onset of cardiovascular events includig sudden cardiac death, myocardial infarction and ventricular arrhythmias has been discribed. The frequency of ventricular premature complexes has also been reported to demonstrate a pattern consisting of a daytime peak and nightime nadir. We tried to see if the same circardian pattern is found in dilated cardiomyopathy patients. We have also studed how various modifying factors such as left ventricular ejection fration and ACE inhibitor use may affect the circardian pattern. METHOD: 24-hour ambulatory electrocaridiographic monitorings were performed in 50 dilated cardiomyopathy patients and 20 control subjects. Patients were prospectively divided in 2 groups based on LVEF and ACE inhibitor use. RESULTS: In dilated cardiomyopathy patients, the expected morning increase in VPC frequency is absent and show a peak in evening. This pattern is not correlated with heart rate. Evening peak is more prominent in low LVEF group and ACE inhibitor non-user group. CONCLUSION: In dilated cardiomyopathy patients, VPC frequency show a peak in the evening.

The present study was undertaken to measure the effects of thiopental and thiamylal on isolated thoracic aortic hlical strips in normotensive Wistar rats(NWR) and spontaneously hypertensive rats(SHR). Phenylphrine(10(-9) ~ 10(-5) M) caused a dose-dependant contraction in thoracic aortic strips contracted with 30mM KCI in NWR and SHR. The contraction induced by 30mM KCI was taken as 100% and the mean absolute values of NWR and SHR were 463+/-30 and 457+/-38mg, respectively. The ED50 of phenylphrine in thoracic aortic strips contracted with 30mM KCI in NWR and SHR was (2.3+/-1.2) X 10(-8) M and (2.1+/-1.1) X 10(-9) M, respectively. There were no significant differences in the contractile response of thoracic aorta from NWR and SHR to 30mM KCI. In helically cut strips of thoracic aorts contracted with 30mM KCI, the cumulative administration of thiopental (10(-5) ~ 10(-3) M) caused a dose related contraction in NWR and SHR. The contraction induced by 30mM KCI was taken as 100% and the mean absolute values of NWR and SHR were 496+/-31 and 541+/-69mg, respectively. There were significant differences (p<0.05 and p<0.01) in the contractile responses of thoracic aorta from NWR and SHR to thiamylal(3X10(-4) and 10(-3) M). The dose-related contraction to thiamylal was greater than that to thiopental in NWR and SHR.

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.
