We report a case of mycosis fungoides with small follicular papules and plaques on the trunk. Histopathological findings showed lymphocytic infiltration within and around the follicular epithelium and Pautrier's microabscess in the epidermis. Immunohistochemical studies showed atypical T lymphocytes infiltrating the follicles and electron microscopic examination revealed the presence of lymphocytes with large convoluted nuclei around the follicles. These findings suggest that the follicular lesions were specific for a special variant of mycosis fungoides.

BACKGROUND: Doppler echocardiography is a non-invasive technique that has been used to evaluate LV diastolic dysfunction. Impaired left ventricular diastolic filling is known to occur in patients with coronary artery disease. Compared with those in normal subjects, Doppler-derived transmitral blood flow velocities have been reported to be reduced during early diastolic filling and to be compensatory elevated subsequent to atrial systole in patinets with coronary artery disease. But stiffness of myocardium normalize the E/A ratio, and normal E/A ratio may reveal increased ventricular filling pressure. We tried to investigate left ventricular filling parameters by Doppler echocardiography in patients with early myocardial infarction, and to compare left ventricular diastolic function regarding infarct location on EKG, one or multivessel disease on coronary angiography, and treatment modality. METHODS: From September 1993 to August 1995, Pulsed wave Doppler echocardiography was performed in patients with early acute myocardial infarction(N=95) and control group(N=20) within 5 days after admission, and parameters of diastolic function was evaluated. RESULTS: Echocardiographic data showed significant differences in mean ejection fraction, mean left ventricular mass, and mean left ventricular mass index between two groups. There was no significant difference in E/A ratio, deceleration time, and isovolumetric relaxation time between two groups. Neither, there was significant difference in each diastolic parameter for infarct related wall on EKG. And there was no significant difference in deceleration time for one or multi vessel disease on coronary angiography, treatment modality(conservative treatment, thrombolytic therapy, or primary PTCA). CONCLUSION: In patients with early acute myocardial infarction, left ventricular diastolic dysfunction was absent. And there was no significant correlation between the presence of diastolic dysfunction and the location of infarct related wall on EKG, or one or multi vessel disease, or treatment modality.

Catecholamine-induced cardiomyopathy associated with neuroblastoma is rarely reported. We report a case of catecholamine-induced cardiomyopathy associated with neuroblastoma in a 33-month-old female that was treated with extracorporeal membrane oxygenation (ECMO). She was tentatively diagnosed with acute myocarditis and presented with hypertension. Because of rapid patient deterioration despite pharmacological treatments, ECMO was applied. ECMO can be helpful in cases of catecholamine-induced cardiomyopathy associated with neuroblastoma.

BACKGROUND: Conventional echocardiography provides fundamental information about mitral valve morphology and function but is often subjective and has a relatively low specificity in evaluating valve calcific deposit, which is critical information for the preoperative decision. We hypothesized that mitral valvular calcification could be detected in standard two-dimensional echocardiograms of mitral valve in vivo by evaluating regional gray level(echo amplitude) using computerized image analysis so that we could overcome the subjectivity and low specificity of conventional echocardiography. METHODS: We tested this hypothesis by performing standard 2.5MHz two-dimensional echoes on mitral valve and myocardium in 30 patients with mitral stenosis, scheduled to undergo mitral valve replacement. We compared gray level of each region of interest in mitral valve and myocardium in stop-frame images with the degree of calcifications identified by pathologic and radiographic examinations. RESULTS: Ratio of mean gray level of mitral valve to mean gray level of myocardium was the most reliable value in evaluating degree of calcification. Quantitatively, region of calcification displayed the ratio of significantly higher value than that of no calcification. In case of anterior mitral valve, the ratio of the evident calcified region was greater than 3.11, that of the region without calcification was less than 2.42 and that of microcalcification was betwwn 2.42 and 3.11. For posterior mitral valve, the ratio of the evident calcified region was greater than 3.50, that of the region without calcification was less than 2.19 and that of microcalcification was between 2.19 and 3.50. The sensitivity and specificity of this method for assessment of degree of calcification was 75% and 100% for anterior mitral valve and 9% and 87.5% for posterior mitral valve. CONCLUSION: Mitral valvular calcification could be detected quantitatively in standard two dimensional echocardiograms of mitral valve in vivo by evaluating regional gray level(echo amplitude) using computerized image analysis.

BACKGROUND: Circadian rhythms have been described for acute myocardial infarction, sudden cardiac death, cerebrovascular disease, ischemic heart disease, and ventricular arrhythmia. Most of studies reported that the frequency of ventricular permature contractions(VPC's) shows a peak in day time. We tried to see that the circadian rhythm of VPC's in hypertension and ischemic heart disease(IHD) patients. And we will also studied the relationship between heart rate and frequencey of VPC's. METHOD: Twenty four hour holter monitoring was performed in hypertensive patients (N=23), ischemic heart disease patients(N=25), and normal control group(N=30). We tested the circadian pattern of VPC's and heart rates and the relationships of the frequency of VPC's and heart rates. RESULT: In hypertension group, a peak incidence of heart rate is between 5 and 8 P.M., in ischemic heart disease group, between 3 and 6 P.M.. In control group, the heart rate shows a peak beteen 1 and 3 P.M.. The frequency of VPC's in hypertension group shows the first peak between 4 and 10 P.M., and the second peak beteen 7 and 10 A.M.. In ischemic heart disease group, they show a peak between 2 and 8 P.M..In control group, there was no circadian variation for the frequency of VPC;s. Both in hypertension and IHD patients group, there was significant correlation between the frequency of VPC's and the heart rates. CONCLUSION: It seemed that VPC' were more frequently occurred in relation to the increase of heart rate in the afternoon, in hypertensive and ischemic heart disease patients.

Dermatomyositis is a disease of unknown etiology characterized by inflammation and degeneration of skeletal muscles and cutaneous abnormalities. Cardiac involvement in dermatomyositis-polymyositis is thought to be rare. In recent year, however, there has been an increasing number of reports on cardiac abnormalities in adult dermatomyositis and polymyositis due to development of noninvasive diagnostic techniques. Categorically, these abnormalities have included electrocardiographic changes, cardiac arrhythmias, congestive heart failure, coronary artery disease, and pericarditis. A 56-year-old woman was admittied to the Ewha womans University Hospital with dyspnea and palpitation. She was diagnosed as having dermatomyositis and followed up our department of Dermatology. Electrocardiogram showed a paroxysmal supraventricular tachycardia at as rate of 195/min. The patient was treated with 240mg/day verapamil p.o, 60mg/day prednisone p.o, there was marked improvement of symptoms. Systematic study of cardiac function utilizing echocardiography, Holter monitoring, thallium-201-scan, and gated blood pool studies were conducted in five newly diagnosed patients with dematomyositis-polymyositis. A significant elevation of serum CPK-MB is indicative of cardiac involvement. Cardiac involvement is a serious prognostic sign. We report a case with the review of the literature.

Acellular pertussis vaccine has been used widely in Korea since 1984. However, because many of the former generations were not inoculated with pertussis vaccine, they may infect infants with pertussis. With this background, we investigated the prevalence of pertussis antibodies in all age groups. Enzyme-linked immunosorbent assay (ELISA) to assess IgG antibodies to pertussis toxin (PT) and filamentous hemagglutinin (FHA) and bacterial agglutination (BA) to assess antibodies to agglutinogen were compared on 842 serum samples which were donated from 11 hospitals in Seoul area. In comparison with age groups under 20 years, antibodies of adults against PT and FHA were maintained. But antibodies against agglutinogen showed no pattem in all age groups. Antibodies to PT were correlated with antibodies to FHA. There was no significant difference in antibody levels between male and female (p<0.05).

Thelaziases in human is an opportunistic infection. The worms usually lie in the conjunctival sac or in the lacrimal apparatus, causing foreignbody sensation, tearing and conjunctival irritation, In most cases, patients find the worms themselves and visit the hospital. Having experienced and confirmed 5 cases of human subconjunctival infestation of Thelazia callipaeda, we report these with literature review.
