Heart failure is a recognized, although uncommon, cause of massive liver cell necrosis, the clinical consequence of which are intermingled with those of cardiac insufficiency in most case. But, hepatic coma is rerely caused by hepatic congestion only. We report the three cases with heart failure resulted in massive liver cell necrosis and fulminant hepatic failure. The manifestations of fulminant hepatic failure were hepatic encephalopathy, jaundice, marked increase of prothrombin time and serum transaminase and there were no evidences of viral hepatitis and toxic hepatitis as a cause of liver failure.

A retrospective comparative analysis was made to assess the relative efficacy and advantage of computedtomograhy (CT) and ultrasound in the diagnosis of pancreatic lesions in patients wtih 33 various pancreaticdiseases. All patients underwent both CT and ultrasound examinations. CT has advantages in delineation ofmorphologic anatomy and its extent, and in identifying abnormal gas and calcification. On the other hand,ultrasound has advantages in evaluation of cystic lesion, pancreatic duct and bile duct. Authors recommendultrasound as a screeing test in the diagnosis of uncomplicated pancreatic duct and bile duct. Authors recommendultrasound as a screening test in the diagnosis of uncomplicated pancreatitis, pseudocyst and pancreatic cancerproducing jaundice, but recommend CT in the diagnosis of complicated pancreatitis, chronic pancreatitis andnon-jaundiced patient with susupected pancereatic cancer. Ultrasound has additional advantage in ultrasound-guidedaspiration biopsy.

The term dilated(congestive) cardiomyopathy refers to a variety of cardiac disorders that have in common ventricular dilation and reduced myocardial contractility, and is derived from the common late clinical manifestation of congestive heart failure. Since echocardiography can evaluate several aspects of anatomical structures and cardiac function, it has provide a valuable contribution to the understanding of ventricular function and diagnosis of dilated cardiomyopathy. The purpose of this study is to perform the echocardiographic evaluation of left ventricular function in 44 patients with dilated cardiomyopathy and to compare the patients with normal individuals. The patients, 24 males and 20 females, had a mean age of 53.0 and body surface area of 1.61m2. Normal individuals as a control group, 10 males and 10 females, had a mean age of 47.2 and body surface area of 1.67m2. Among 44 patients with dilated cardiomyopathy, 22 cases had a history of heart failure and in 15 cases systolic murmur was heard at the apex. The cardiothoracic ratio was 0.7+/-0.1 on chest X-ray which showed significant difference when compared to normal control group, being 0.4+/-0.1(p<0.01) One case showed left ventricular thrombus and in 8 cases small mounts of pericardial effusion were noted. Among the 44 patients two had uremia, one had a history of myocarditis, one patient was young female whose illness began during the peripartum period and one had a diabetes mellitus. Results obtained were as follows; 1) Mitral valve echocardiogram (1) DE amplitude and EF slope of mitral valve(16.5+/-3.3mm and 83.5+/-3.65mm/sec respectively) showed significant decrease when compared to normal control group (20.1+/-3.0 mm and 102.4+/-28.9 mm/sec respectively) (p<0.01 and p<0.05). (2) EPSS (25.5+/-7.6mm) and the distance between posterior cusp of mitral valve and left ventricular posterior wall (9.1+/-2.1mm) showed significant increase (p<0.01) when compared to normal control group (7.1+/-2.1mm and 5.9+/-1.2mm). The ratio of the separation of two mitral leaflets to the left ventrticular diastolic dimension (0.4+/-0.1) showed significant showed significant decrease in patients when compared to normal control group (p<0.01) (3) Among 44 patients with dilated cardiomyopathy, 12 cases showed B-notch in mitral valve. 2) Echocardiographic findings of aortic valve. Left atrial size was markedly increased (37.7+/-7.5mm) when compared to nomal control group (29.1+/-4.9) (p<0.01). The ratio of left atrial size to aortic dimension was 1.3+/-0.3, showing significant increase when compared to normal control group (0.99+/-0.3) (<0.01). And 4 cases showed systolic notch in aortic valves. 3) Echocardiographic findings of left ventrcle and ventricular septum. (1) Left ventricular diastolic and systolic dimensions (41.8+/-7.8mm/m2 and 36.7+/-7.2mm/m2) were markedly increased in patient with dilated cardiomyopathy, when compared to normal control group (30.4+/-2.6mm/m2 and 11.4+/-3.2mm/m2) (p<0.1, both). Left ventricular diastolic and systolic volume (181.5+/-91.0ml/m2 and 136.6+/-69.7ml/m2) were also significantly higher in patients with dilated cardiomyopathy when compared to normal control group (79.1+/-23.8mm/m2 and 19.4+/-2.5ml/m2) (p<0.01, both). (2) Ejection fraction (0.32+/-0.10) percent fractional shortening (12.3+/-4.6) and mVcf (0.5+/-0.2 cric/sec) showed significant decrease in patients when compared to normal control group (0.74+/-0.05, 34.6+/-6.7 and 1.4+/-0.2) (p<0.01, all). Thus, We could find the reduced myocardial contractility in dilated cardiomyopathy. (3) Systolic amplitudes of venticular septum (LSa) and ventricular posterior wall (Ena) were markedly decreased (p<0.01). The sum of both values (LSa+ENa) also showed significant decrease (12.0+/-4.2mm) when compared to normal control group (p<0.01) (4) Thickness of ventricular septum and ventricular posterior wall showed slight increase in patients, but there was no significant changes when compared to normal group. 4) Systolic time interval Echocardiograms showed significant increase in ratio of preejection period to ejection time, when compared to normal group (p<0.01). Thus, the author observed that in dilated cardiomyopathy the contractility of left ventricle was significantly reduced and the left ventricular diameter and diastolic volume of left ventricle showed marked increase. And also the decreased motions of ventricular septum and posterior wall of left ventricle were noted.

In order to review the epidemiological data of cardiovascular diseases, statistical observation was made on the 7,271 patients with cardiovascular diseases who were treated in the Department of Internal Medicine, Han-Yang University Hospital during the 10 year period from May 1972 to December 1981. A. General Findings (1) Cardiovascular disease was seen in 18.6% out of a total 39,004 medical inpatients treated during this 10 year time span. (2) Incidences of cardiovascular disease seemed to increase in frequency in consecutive years, especially incidence of coronary heart disease and arrhythmia. (3) Incidence of cardiovascular disease occurred most frequently to patients in their fifth decade, and next most frequently to those in their sixth and fourth decade, in that order. (4) The overall ratio of male to female incidence of cardiovascular disease was 1:1. B. Specific Epidemiology (1) Hypertension was the most common form of cardiovascular problem, accounting for 52.9% of patients with cardiovascular disease and 9.9% of the total medical in-patients population. Incidence of hypertension occured most frequently in the fifth decade of life. It occured next most in the sixth and fourth decades, in that order. The male to female ratio of incidence of hypertension was 1:1. Patients with malignant hypertension made up 5.9% all hypertension patients. (2) Patients with rheumatic heart disease made up 6% of those patients with cardiovascular diseases. Male to female ratio of incidence of rheumatic heart disease was 1:2.4. The most common form of this disease was mitral valvular disease, but isolated aortic valvular disease proved to be rather uncommon in this study in Korea. (3) Coronary heart disease made up 15.5 % of all incidence of cardiovascular diseases. It occured most frequently to patients in their fifth and sixth decades, and in a male to female ratio of 1.5 to 1. (4) Congenital heart disease made of 0.9% of the total incidence of cardiovascular diseases with ventricular septal defect as the most common form of this disease. (5) The remaining forms of cardiovascular diseases diagnosed during the time span of this study were arrhythmia 16.8%, cor pulmonale 1.4%, cardiomyopathy 1.3%, peripheral vascular disease 1.0%, pericarditis 1.0%, thyrotoxic heart disease 0.8%, endocarditis 0.5%, postpartum cardiomyopathy 0.3%, myxedematous heart disease 0.1%, and miscellaneous heart ailments 1.5%.

PURPOSE: The purpose of this study was to determine current trends and the mode of future development in the field of medical radiology and to promote research among the nation's radiologists by analyzing the contents of the Korean Radiologic Society(JKRS) and Radiology. MATERIALS AND METHODS: The number of articles published in JKRS each year between 1990 and 1994 was counted. The research articles in JKRS(n=740) and in Radiology(n=1748) between 1992 and 1994 were categorized according to the objective, type, topic, materials, and radiologic techniques of their contents on the basis of predetermined criteria. Domestic Masters theses(n=126) and doctoral dissertations(n=75) accepted between 1990 and 1994, and domestic materials published in international journals(n=416) between 1986 and 1994 were also categorized using the same criteria. RESULTS: The greatest increase in the number of articles published in JKRS was seen during 1994. The majority of these aimed to retrospectively analyse the findings of diseases while the majority of articles published in Radiology dealt prospectively with the development and/or evaluation of diagnostic methods. More variety of topics and issues was seen in Radiology than in JKRS. The number of articles of domestic materials published in international journals increased from1986 to 1994, while the number of articles of foreign materials published in korea was relatively stationary. A significant number of theses and dissertations dealt, mostly prospectively, with studies of pathophysiologic and/or pharmacologic mechanisms using animal models. CONCLUSION: In order to understand both current trends and the direction and mode of future developments in the field of radiology, and to be able to actively deal with challenges at the forefront of radiologic development, it is essential to review research articles published in radiology-related journals.

With the development of gray scale ultrasonography, detection and evaluation of hepatic parenchymal diseaseincluding space occupying lesions are easitly performed and frequently used in the world. Thirty-five cases ofhistopathologically proven and ultrasonographically suggested hepatocellular carcinoma are retrospectivelystudied. The results were as follows; 1. Ultrasonographic findings of hepatocellular carcinoma show hyperechoicpattern in 22 cases (63%), hypoechoic pattern in 2 cases (6%), and mixed pattern in 11 cases (31%). 2. The marginof tumor is ill-defined in 19 cases (54%) and well defined in 16 cases (46%). 3. The size of tumor by sonographicmeasurement was larger than 5cm in diameter in 33 cases (94%). 4. The number of tumor is solitary in 19 cases andmultiple in 16 cases. The sites of involved lobe were right lobe in 22 cases (63%), left lobe in 2 cases (6%), andboth lobes in 11 cases (31%). 5. Associated sonographic findings were hepatomegaly with focal contour change in 25cases (71%), splenomegaly in 16 cases (46%), cirrhosis of liver in 15 cases (43%), ascites in 11 cases (31%) andtumoral thrombosis in portal vein in 8 cases (23%). 6. The sex ratio is 6:1 male predominence and the age rangesfrom 32 to 76 years with highest incidence in 5th and 6th decades.

A retrospective analysis of the ultrasonographic findings of 9 cases of tuberculous abscess, 5 cases of pyogenic abscess and 2 cases of hematoma of psoas and adjacent muscles was made. Fluid collection with or without internal echoes was seen in 12 cases out of total 16 cases. Other findings were 2 cases of only muscle swelling, 1 case of highly echogenic mass.like appearance and 1 case of fluid collection with septae. Ultrasonography is considered an accurate method in identifying early pathologic changes of the psoas muscle and determining its extent. and in differentiating tumor from fluid collection of the psoas muscle. Authors dare to say that ultrasound examination is a procedure of choice in the diagnosis of psoas abscess and hematoma.

BACKGROUND: Arthroscopic stabilization of torn coracoclavicular (CC) ligaments gained popularity recently. However, loss of reduction after the operation and complications unique to this technique involving tunnel placement through the distal clavicle and coracoid process are concerns. The purpose of this study was to report intraoperative and early postoperative complications associated with this procedure. METHODS: This study retrospectively evaluated 18 consecutive patients who had undergone arthroscopic stabilization for torn CC ligaments between 2014 and 2015. The indications for surgery were acute or chronic acromioclavicular dislocation and acute fracture of the distal clavicle, associated with CC ligament disruption. Clinical outcomes were evaluated with the American Shoulder and Elbow Surgeons (ASES) and the University of California, Los Angeles (UCLA) scores. Intra- and postoperative complications and reoperations were investigated. RESULTS: There were six female and 12 male patients with a mean age of 47 years (range, 22 to 86 years). At a mean follow-up of 17 ± 10 months (range, 10 to 28 months), the mean ASES score was 88.8 ± 19.9 and the mean UCLA score was 30.9 ± 5.2. Intraoperatively, seven complications developed: breach of lateral cortex of the coracoid process in five patients, medial cortex of the coracoid process in one, and anterior cortex of the clavicle in one. Postoperative complications developed in eight patients: four ossifications of the CC interspace, four tunnel widening of the clavicle, one bony erosion on the clavicle, and one superficial infection. A loss of reduction was found in six patients. Reoperation was performed in three patients for loss of reduction in two and superficial infection in the other. CONCLUSIONS: Arthroscopic CC stabilization resulted in high rates of intraoperative and early postoperative complications. Most of them were related to the surgical technique involving bone tunnel placement in the coracoid process and the clavicle.

Since the introduction of shoulder arthroplasty by Neer in 1974, the design of not only the glenoid component but also the humeral component used in shoulder arthroplasty has continually evolved. Changes to the design of the humeral component include a gradually disappearing proximal fin; diversified surface finishes (such as smooth, grit-blasted, and porous coating); a more contoured stem from the originally straight and cylindrical shape; and the use of press-fit uncemented fixation as opposed to cemented fixation. Despite the evolution of the humeral component for shoulder arthroplasty, however, stem-related complications are not uncommon. Examples of stem-related complications include intraoperative humeral fractures, stem loosening, periprosthetic fractures, and stress shielding. These become much more common in revision arthroplasty, where patients are associated with further complications such as surgical difficulty in extracting the humeral component, proximal metaphyseal bone loss due to stress shielding, intraoperative humeral shaft fractures, and incomplete cement removal. Physicians have made many attempts to reduce these complications by shortening the stem of the humeral component. In this review, we will discuss some of the limitations of long-stem humeral components, the feasibility of replacing them with short-stem humeral components, and the clinical outcomes associated with short-stemmed humeral components in shoulder arthroplasty.
