An analysis of echocardiograms was made in 50 patients with pericardial effusion of various origins, diagnosed by clinical and M-mode echocardiographic examinations. In these cases the estimated volume of pericardial effusion ranged between 40 ml and 999 ml. The width of echo-free space behind the left ventricular wall which reflect the amount of effusion showed a significant positive correlation with the systolic excursion and the diastolic mean velocity of both right and left ventricular epicardial surfaces. The echocardiographic patterns of so-called pseudo-mitral valve prolapse and a notch on the right ventricular epicardial surface during systole were found more frequently in patients with large pericardial effusion. Thus, in pericardial effusion, and echocardiographic examination is useful for the visualization of the abnormal motions of cardiac structures as well as for its diagnosis.

BACKGROUND: Decreased heart rate variability(HRV) has been shown to be an independent predictor of poor outcome after acute myocardial infarction, Spectral analysis of HRV has recently been shown to be a reliable noninvasive test for quantiative assessment of cardiovascular autonomic regulatory response. We estimated the reproducibility and circadian rhythm of HRV parameters in patients with acute myocardial infarction. METHODS: Three consecutive 24-hour ambulatory electrocardiographic recordings were made in 24 patients with acute myocardial infarction, with 10~14 days after the acute attack, and analyzed for HRV parameters of both frequency and time domains. Parameters of frequency domain include low frequency(LF) and high frequency(HF) components. Parameters of time domain include sdRR, SDANN, SD, pNN50, rMSSD, HRV index. RESULTS: Mean total, low frequency and high frequency amplitude spectral densities were 33msec, 19msec and 11msec, respectively. Mean values of sdRR, SDANN, SD, rMSSD, pNN50 and HRV index were 103msec, 90msec, 47msec, 28msec, 7% and 32, respectively. Coefficients of variation(CV) of total amplitude spectral density, and low and high frequency components were 7%, 9% and 12%, respectively. CV of most HRV parameters of time domain were also around 10% except rMSSD and pNN50. Heart rate increased in the morning to be sustained during the day time and decreased in the night. Heart rate variability of high frequency component decreased in the early morning to be sustained during day time with increase in the night. CONCLUSIONS: We conclude that in the predischarge period of acute myocardial infarction, HRV parameters of frequency and time domains are reproducible and there are some morning fall of cardiac vagal activity.

BACKGROUND: Much of the recent understanding of hypertensive has focused on the importance of concomitant atherosclerotic risk factors in addition to the blood pressure itself and has created new therapeutic challenges. METHODS AND RESULTS: We conducted a prospective study to determine the prevalence rates of hyperlipidemia, smoking, diabetes, obesity and left ventricular hypertrophy(LVH) in 185 hypertensive subjects. Serum levels of total cholesterol, triglyceride and HDL-cholesterol were measured by enzymatic method. 1) Mean values of serum total cholesterol, triglyceride, HDL-cholesterol, LDL-cholesterol and atherogenic index were not significantly different between sex and resident area. 2) The most frequent risk factor in hypertensive subjects was overweight, followed by M-mode echocardiographic LVH, hypertriglyceridemia, high LDL-cholesterol levels, low HDL-cholesterol levels, hypertriglyceridemia, electrocardiographic LVH, and diabetes. 3) The prevalence rates of both total cholesterol levels over 240mg/dl and LDL-cholesterol over 160mg/dl were about 20%, regardless of sex and resident area. CONCLUSION: These results indicate that hypertensive subjects have many concomitant risk factors of atherosclerosis. Hypercholesterolemia(> or =200 mg/dl), M-mode echocardiographic LVH and overweight among the selected risk factors were observed in more than a half of the hypertensive subjects, regardless of sex and resident area. These findings suggest that for the effective management of hypertensive subjects, physician should not only treat hypertension itself, but also control the concomitant risk factors.

The relationship between respiratory infections and exacerbations of wheezing in patients with wheezy bronchitis or asthma has been described. Most respiratory infections were viral or Mycoplasma pneumoniae. This study was performed to evaluate the effect of Mycoplasma pneumoniae infection on bronchial reactivity and atopic background. 106 patients with Mycoplasma pneumoniae pneumonia who were admitted to the department of pediatrics, Fatima Hospital, Taegu during the period of two years from January 1989 to December 1990 were involved in this study. The results were as follows 1) Out of 106 cases, 69 were male,37 were female and 34.9% of the cases were between 5~6 years of age. 35 cases(33.0%) had wheezing and the incidence of wheezing were higher in male than in female. 2) The incidence of wheezing was high in the patients with serum IgE level higher than 200IU/ml, patients with past and family history of allergy and the patients fed with formula feeding in infancy. 3) Eosinophils and the associated maxillary sinusitis had no effect on the incidence of wheezing. 4) The recurrence of wheezing was higher in Mycoplasma pneumoniae pneumonia with wheezing(26.8%) than in patients without wheezing(3.8%).

Bartter's syndrome is a rare tubular disorder characterized by hypokalemic, hypochloremic metabolic alkalosis, hyperreninemic hyperaldosteronism, hyporesponsiveness to pressor agents, and juxtaglomerular apparatus hyperplasia. We report here a case of Bartter's syndrome in a 5 month-old male infant who improved with potassium supplements. In addition to a case report, brief review of related literatures was done.

Venous hemangioma is a vascular tumor that has been reported by such diverse names as; "cirsoid aneurysm", "arteriovenous hemangioma", "acral arteriovenous tumor" according to the author's opinions of its origin and histopathologic classification. It is benign and rarely biopsied, and it is also rarely reported in dermatology literature. We present two cases of venous hemangioma. The first case was a 64-year-old man who was presented with an elliptical dark-red plaque with overlying several grouped papules on the left periorbital area which had been present for 7 years. The second case was a 56-year-old man who was presented with a single red papule on the right postauricular area which had been present for 4 months. Histopathologically, there were a well-circumscribed proliferation of thick-walled muscle-containing blood vessels in the dermis. Intermingled with the thick-walled blood vessels, there were also thin-walled dilated blood vessels. In both cases, the thick-walled blood vessels resembled arteries, but they lacked elastic fibers on the Verhoeff van Gieson stain.
