Hypertensive left ventricular hypertrophy(LVH) was considered to be a physiologic adaptation to the increased afterload of left ventricle, but recent studies revealed that LVH was one of the most important target organ damage in essential hypertensive patients & cardiovascular morbidity was increased in patients with hypertensive LVH. Hypertensive LVH could be classified into three types : concentric LVH, disproportionate septal thickening(DST), and left ventricular dilatation. Relatively high incidence of DST in hypertension has bee reported after clinical introduction of echocardiogram. But, the mechanisms for the development of DST and its clinical significance have not been elucidated exactly. In order to assess left ventricular diastolic function in hypertensives with DST, the authors performed phonocardiogram, M-mode, and pulsed Doppler echocardiogram in 15 normotensive control(group A : 5 male, 10 female, 44.4+/-7.7 years), 15 hypertensives without LVH(group B : 5 male, 10 female, 45.5+/-8.6 years), 85 hypertensives with DST(group C : 9 male, 16 female, 47.5+/-8.6 years) and 15 hypertensives with concentric LVH(group D : 8 male, 7 female, 47.7+/-6.1 years). The obtained results were as follows : 1) Left ventricular ejection fraction was 71.6+/-6.3% in group A, 71.9+/-7.5% in group B, 731+/-7.0% in group C, and 70.3+/-10.3% in group D. Ejection fraction was not significantly different in each other group. 2) Left ventricular mass index(LVMI) by echocardiogram was 87.8+/-20.6g/m

The authors reviewed findings of enhanced abdominal computed tomographic (CT) scans to the difference between a higher dose of conventional ionic contrast media(iothalamate meglumine) and a lower dose of a new, nonionic contrast material (ioversol). One hundred adult patients were divided into two groups. Each group consisted of 50 patients. Iothalamate meglumine and ioversol were intravenously administered in each group. The ratio of the male to female in the former was 28.22, and the latter 29:21. We examine the degree of renal streak artifact and measure the Hounsfield number of urine in renal collecting system. There were significant differences of the degree of the streak artifact depending upon the osmolality of contrast media used and that was related with urine CT number (P value<0.005). We authors conclude that nonionic low osmolar contrast media is prone to cause streak artifacts and distortions of renal image than conventional ionic high osmolar contrast media.

Proper positioning of pulmonary artery catheter and predicting distal migration of it during cardiopulmonary bypass is important for the prevention of perioperative complication of pulmonary artery rupture. The authors therefore examined the insertion length of pulmonary artery catheter via right internal jugular vein at which catheter tip was advanced to the most proximal position where pulmonary capillary wedge pressure could be obtained. And also the distal migration is measured by comparing the difference between prebypass and postbypass corrected length. Just before bypass, pulmonary artery catheter was arbitrarily receded 5cm for the prevention of spontaneous distal migration and wedging. The subjects were 47 patients who underwent open heart surgery (valve replacement, coronary artery bypass graft) during the period of November, 1992 through April, 1993. The results were as follows. 1) The insertion length of pulmonary artery catheter from skin to the right ventricle inlet, pulmonary artery inlet and pulmonary capillary wedge position were 26.5+/-3.0 cm, 36.8+/-4.9 cm and 46.1+/-5.7 cm respectively. 2) There were no significant statistical correlations between insertion lengths and patient constitutions such as body weight and height(r=0.144, r=0.032). 3) Locations of catheter tips were distributed to the 0.9+/-3.1 cm left to the spinous process, 1.9+/-1.6 cm inferior to the carina ; mostly LLQ of the lung field(51%). 4) During cardiopulmonary bypass, pulmonary artery catheter tips were migrated distally in 93.6% of the cases and the migration lengths were 2.7+/-2.0 cm. 5) There were no major perioperative complications caused by pulmonary artery catheterization. These results suggest that 5 cm withdrawal of pulmonary axtery catheter just before cardiopulmonary bypass can prevent the fatal complication of pulmonary artery rupture owing to its spontaneous distal migration.

We have studied the vasodilating effect of bolus doses of sodium nitroprusside (SNP), nitro- glycerin (NTG), and isosorbide dinitrate (ISDN) in 40 patients during cardiopulmonary bypass with a constant pump flow. Blood volume of the venous reservoir and mean arterial pressure were recorded for 10 minutes after drug administration to detect changes in venous capacitance and arteriolar resistance. SNP 500 ug decreased mean blood pressure significantly more than NTG and ISDN compared with placebo. NTG 500 ug decreased mean blood pressure transiently at 1-4 min but significantly reduced reservoir blood volume. ISDN 500 ug increased mean blood pressure after drug administration, decreased reservoir blood volume less than NTG. We could conclude that SNP was more effective arteriolar vasodilator than NTG and ISDN, but NTG and ISDN were effective as a venodilator during cardiopulmonary bypass.

The eruptive collagenoma is a connective tissue nevus without family history. We report a case of eruptive collagenoma in a 5 year old boy, who had multiple, variable sized orange colored nodules on his back since birth. The histopathologic finding showed increased number and size of collagen fiber and increased dermal thickness.

Four patients were treated who had limited flexion of the hips and various degrees of contracture of the abduction and external rotator muscles because of fibrosis of the gluteus maximus muscle. Each patient had a typical restriction of motion such that an affected hip could not be flexed in the usual sagittal plane, but had to be flexed in abduction. Genetic, congenital and postnatal factors have been suggested as the cause of fibrosis of gluteus maximus muscle. Three of the 4 patients reported here are of congenital origin and another one is of postnatal factor repeated intramuscular injections. Excellent correction of the hip contracture was achieved in all patients by division of the fibrotic bands.

SLE is an acute and/or chronic disease of a complex autoimmune nature affecting the skin, joints, serous membranes, kidney, central nervous system, cardiovascular system, and other organs of the body. Cardiac abnormalities are one of the most important clinical manifestations of SLE, contributing significantly to the morbidity and morality of the disease. We report a woman, a 30-year-old with SLE, who developed symptoms and echocardiographic signs of dilated cardiomyopathy. She had a history of acute myocardial infartion 7 months ago and has taken cyclophosphamide pulse therapy owing to lupus nephritis. The diagnosis of the condition was based only on clinical and echocardiographic grounds without coronary angiography or endomyocardial biopsy. She received high dose steroid (methylprednisolone pulse therapy 1mg/kg for 3 days) and conservative therapy for heart failure. The association of SLE with dilated cardiomyopathy has not been described with review of previous literatures. For the probable causes of her dilated cardiomyopathy, we suggest that they are due to coronary arteritis or cyclophosphamide-induced myocarditis with regard to her past history of myocardial infartion and cyclophosphamide therapy for lupus nephritis. The incidence of dilated cardiomyopathy, complicated with SLE is rare, but it has ap increased risk for unfavorable outcome. It reserves to pioneer the method of early diagnosis and management which will improved the morbidity and mortality of the disease.
