The investigation of systolic time intervals and hemodynamics was performed in 42 patients with liver cirrhosis by noninvascive methods. The patients were divided into four groups according to the presence or absence of anemia and/or ascites: i.e. group I; cirrhosis without anemia and ascites, group II; cirrhosis with ascites only, group III; cirrhosis with anemia only, and group IV; cirrhosis with ascites and anemia. In the resting state of the patients, the systolic time intervals and hemodynamic data were measured by the high speed simultaneous recordings of electrocardiogram, phonocardiogram, carotid and femoral arterial pulse tracings, and compared with those obtained from 155 normal adult subjects. 1. The pulse were increased considerably in group IV, and diastolic blood pressure was elevated in group II with significance. 2. The stroke volume and cardiac output were increased significantly in group III. 3. The peripheral resistance was reduced particularly in group III, and the volume elasticit coefficient was decreased in group IV. 4. The QS1 interval was prolonged significantly in group II and IV, but QS1 interval corrected by multiple regression equation proposed by our laboratory (illustrated in the text) did not show significant difference compared with that of normal subjects. 5. The left ventricular ejection time(LVET) and total electromechanical systole(QS 2) appeared to be shortened in group II and IV, but the corrected LVET and QS 2 were not different significantly from those of the normal subjects

5.The Relationship between Pulmonary Function and Serum Uric Acid Level in the Korean Population
Korean Journal of Health Promotion 2019;19(4):196-201
BACKGROUND:
Forced vital capacity (FVC), forced expiratory volume in the first second (FEVâ‚), and the ratio of FEVâ‚ to FVC (FEVâ‚/FVC) are considered as the major spirometry parameters. Serum uric acid is associated with increased risk of gout and cardiovascular disease. We analyzed the relationship between pulmonary function and serum uric acid level in the Korean men and women.
METHODS:
This study was based on the data collected during the 2016 Korea National Health and Nutrition Examination Survey (KNHANES VII-1). A total of 3,411 adults were retrieved from KNHANES VII-1. Among 3,411 adults, 1,500 were men and 1,911 were women.
RESULTS:
In this study, a significant negative correlation was observed between serum uric acid level and pulmonary function values only in females. Also, in the male non-smoker group, pulmonary function values were negatively associated with serum uric acid level (FVC %predicted, β=−0.014; FEV₠%predicted, β=−0.015).
CONCLUSIONS
In this study, hyperuricemia was associated with the low lung function in males and females. In order to obtain an accurate assessment of the association between hyperuricemia and pulmonary function values, further prospective cohort study in the future is necessary.

Proliferating trichilemmal tumor is a rare benign tumor of skin appendage. It is usually solitary, more common in women after the fourth decade of life, and almost exclusively confined to the scalp and back of the neck. We report herein an unusual case of proliferating trchilemmal tumor which occurred on the knee.

BACKGROUND: The pattern of left ventricular filling as depicted by Doppler echocardiographic transmitrial flow velocities has been used to left ventricular diastolic properties. Especially, altered transmitral flow by abnormal myocardial wall motion and left ventricular function in ischemic heart disease, was predicted during exercise test. METHODS: To determine the effects of exercise on Doppler echocardiographic measures of left ventricular diastolic filling, we studied 15 angina pectoris patients and 20 normal control subjects. Transmitral flow measurements comprised peak and integrated early passive(E) and late atrial(A) filling velocities and diastolic filling period. RESULTS: Heart rate in negative exercise treadmill test group was 70/min at rest, 111/min just after exercise, and 86/min at 5 minutes after exercise. Positive exercise treadmill test group was 69/min, 109/min and 82/min, respectively. DFP and E duration were also significantly decreased after exercise in group with negative treadmill exercise test. In positive treadmill exercise group, peak A was significantly increased from 0.57+/-0.15m/sec to 0.75+/-0.20m/sec at just after exercise(p<0.01), 0.67+/-0.12m/sec at 5 minuties after exercise. DFP and E duration were also significantly decreased after exercise. CONCLUSION: Doppler echocardiographic transmitral flow was altered by abnormal regional wall motion and left ventricular dysfunction in ischemic heart disease during exercise test. The use of Doppler echocardiography for this purpose is limited, however, because a number of variables may influence transmitral flow patterns, including age, preload, afterload and systolic function.

BACKGROUND AND OBJECTIVES: Dobutamine stress echocardiography (DSE) with 2D echocardiography (2DE) is one of the time-consuming procedures in the diagnosis of coronary artery disease (CAD). Moreover, the accuracy of DSE with 2DE depends on the operator's skill or bias during the image acquisition. This study was conducted to determine the feasibility and accuracy of DSE with real-time 3D echocardiography (RT3DE) for the diagnosis of CAD. SUBJECT AND METHODS: 62 patients (RT3DE: 36, 2DE: 26), suspected of angina pectoris and post-revascularization ischemia, underwent DSE and coronary angiography (CAG). Image acquisition was performed at the baseline, and at 4 times during the dobutamine infusion and recovery stages. The procedure time (from the baseline to the end of the peak dose stage) was recorded. Off-line analyses of the volumetric images acquired with RT3DE were performed using 3D computer software (TomTec, Co.). Digitized quad-screen images acquired with 2DE were analyzed using the 2DE review system (ProSolv 4.0). >50% luminal diameter stenosis of any coronary artery on CAG was defined as significant coronary artery stenosis. RESULTS: The procedure time of DSE with RT3DE was significantly shorter than that of DSE with 2DE (25+/-4 vs. 37+/-4 mins, p<0.001). There was no significant difference in the sensitivity (p>0.05) or specificity (p>0.05) between the two procedures. CONCLUSION: DSE with RT3DE seems to be a feasible and less time consuming diagnostic procedure, probably providing comparable sensitivity and specificity for the detection of coronary artery stenosis, than DSE with 2DE.
