A Clinical study was done on 90 cases of acute myocardial infarction admitted to Busan Wallace Memorial Baptist Hospital from January, 1977 to Febuary, 1983. The following results have been obtained. 1) The ratio of male to female was 2.2:1. The most age group were 5th decades(35.6%) and over 5th decades(5th decades and 6th decades) were two-thirds of all age group. And annual incidency were increasing tendencies, in 1980-1982 than 1977-1979. 2) Between the preceding diseases and the risk factors, the most common cause was the smoking (60%). And other associated diseases and factors were hypertension(54.4%), hypercholesterolemia (43.8%), hyperlipidemia(51.4%) and angina pectoris (34.4%). 3) The most common inducing factor was physical exertion(33.3%). And others were emotional stress(23.3%), alcohol drinking(10%), rest and sleeping(5.6%). 4) The major symptoms of acute myocardial infarction were precordial or epigastric pain(96.7%), dyspnea(53.3%), radiating chest pain (51.7%) and painless infarction(3.3%). 5) On laboratory data, there were leukocytosis in 50.5% increased SGOT in 68.6%, increased serum LDH in 75.9% and cardiomegaly in chest x-ray film were 82 percents. 6) The ratio between the anterior and inferior infarction on EKG was 1.9:1. 7) When admission, normal sinus rhythms on EKG were 59 percents. And the common associated electrocardiographic abnormalities were ventricular premature beat (23.6%), atrial fibrillation(15.7%), first degree A-V block (15.7%), left ventricular hypertrophy(15.7%). The most common abnormality was ventricular premature beat(23.6%). 8) The mortality rate of acute myocardial infarction was 10 percents. The causes of death were heart failure(33.3%), ventricular arrhythmia(33.3%), sudden death (22.2%) and cardiogenic shock(11.1%).

Multilocular cystic renal cell carcinoma appears to be a distinct and rare subtype of renal cell carcinoma with characteristic gross and microscopic features. Multilocular cystic renal cell carcinoma should be separated from multilocular cyst, multilocular cystic nephroma, and renal cell carcinoma with cystic degeneration. We present a case of multilocular cystic renal cell carcinoma. A 61-year-old man presented with right flank pain for 4 years. The computerized tomography revealed multilocular cystic mass in the upper pole of right kidney. The cystic mass measured 4.5x4 cm. The cyst was multilocular and locules not communicated with each other. The solid area was not present. Microscopically, the locules were lined by flat or cuboidal neoplastic clear cells. The clear cells were focally aggregated in the septa. The nephron was not present in the septa.

Pancreatic pseudocyst occurs as a complication of pancreatitis or trauma, which results in the escape of pancreatic enzymes from the parenchyma or ductal system of pancreas. At that time, serum amylase may have returned to normal level, and the patient may be subjectively asymptomatic. In this phase, the radiologic findings are relatively greater significance than laboratory data. In the conventional radiologic study, pancreatic pseudocyst have been frequently confused with other retroperitoneal mass, but recently with clinical application of ultrasound and CT scan, more accurate diagnosis can be obtained. The brief results are as follows; 1. Male to female ratio was 3:2 in 15 patients. Incidence was most common in young adult age. Most frequent symptom was epigastic pain, and which was noted in 11 cases of patients. 7 cases of patients had past history of abdominal trauma and past history of pancreatitis was only in 1 case. Most common laboratory finding was leukocytosis in 8cases of patients and elevated serum amylase was also noted in 7 cases. 2. In each 5 cases of patients, plain chest roentgenologic evidence of left side pleural effusion and hemidiaphragm elevation were observed. 3. On flat abdomen film, soft mass shadow was visualized in 8 cases of patients. On UGI series, evidence of retrogastric space widening was observed in 11 cases of patients. 4. The location of pseudocyst is mainly in body and tail of pancrease in 11 cases of patients. 5. More accruable diagnosis can be obtained through application of ultrasound and CT scan.

Ultrasonography affords an accurate assessment of the presence, size, location and internal consistency of apelvic mass. We present our experience of 105 cases of pelvic masses in female patients by ultrasonography, andthe results are as described; 1. Ultrasonography is nonspecific, however, the possibility of mucinous cystadenomaof ovary, teratoma(dermoid cyst), uterine leiomyoma and trophoblastic disease can be suggested due to theircharacteristic internal consistency. 2. This smooth internal septation seen within mucinous cystadenoma, eccentricsolidmural component of dermoid cyst, enlarged uterine wall with lobulated outer margin of leiomyoma, andyesicular appearance of trophoblastic disease were the specific sonographic features. 3. Loculated ascites and hydronephrosis were identified with malignant ovarian neoplasm and pelvic metastasis. 4. Accurate ultrasonographicdiagnosis was made in 88 cases (83.7%) and it may be improved with clinical history of the mass in question.

There has been no adequate diagnostic method for the diagnosis of intrascrotal lesions until recent days. Butafter the development of radionuclide testicular scan, early and relatively accurate diagnosis of the testicularlesions are possible. So the authors analyzed the 32 cases of patients who were examined by testicular scan andconfirmed by follow up study or operation, and the results are as follows; 1. These 32 cases consists of 13 casesod epididymitis, 7 cases of testicular torsion, 4 of cryptorchism, 2 of testicular tumor and etc. The over alldiagnostic accuracy is about 69%. 2. In epididymitis, the diagnostic accuracy is 85%(11/13) and the findings ofscan are increased perfusion in radionuclide angiogram and hot activity noted mainly in peripheral portion of thetesticle in static image. 3. In cases o testicular torsion, diagnostic accuracy is 86%(6/7). Acute torsion showsnormal perfusion in angiogram and round cold area instatic image. But in missed torsion, perfusion is increasedand round cold area wit surrounding hyperemia is noted in static image. Radionuclide testicular scan seems to benoninvasive, inexpensive, easily available and simple to perform with low gonadal radiation dose. So it can bevery useful as the first study in patients with acute testicular symptoms.

From March 1985 to Sep.1985, Transcatheter hepatic arterial embolization was perfromed in 17 primary heptomaand 8 metstasis of liver in Department of Radiology, Yonsei University College of Medicine. Metastatic cancers ofliver were one nasopharyngeal cancer, one small bowel leiomyosarcoma, one gall bladder cancer and 5 colon cancers.The used embolization materials were the followings: Gelfoam particles for one primary hepatoma, 95% absoluteethanol for 4 patients, Ivalon(250-590micro m) for 19 patients and autologous blood clots for one metastasis, Theresults were summarized as the follows: 1. The devascularization of tumor vessels in post-emblization hepaticangiogram was complete in 6 primary hepatom and one metastasis and partial in 11 primary hepatoma and 7metastasis. 2. In the follow-up CT evaluation 3 to 4 weeks after embolization, well necrotic density was revealedin 8 primary hepatoma and one metastasis. 3. The complications were fever with higher than 38 degrees C(92%),abdominal pain (72%) and nausia or vomiting(40%). They were subsided wtihin one to 7 days after embolization. 4.In liver function study, sGOT and sGPT were elevated in 80% of total cases and returned to normal within 15 to 30days. LDH was variable. In 4 cases of absolute ethanol infusion, above liver enzymes were markedly elvated as 10times or more as normal range.

Out of 75 patients who were admitted to our hospital because of abdominal trauma and were undergone theprocedures such as ultrasonography and/or CT scan within 24 hours of abdominal trauma due to suspected abdominalorgan injury. We analyzed the results of 38 patients who were confiremd of diagnosis by operation, follow-up CTscan or ultrasonography. 1. In the abdominal organ injury, solid organ injury consists of 8 cases of spleenlaceration, 1 of splenic subcapsular hematoma, 7 of hepatic laceration, 7 of pancreas laceration, 3 of renallaceration, and 3 of subcapsular hematoma of kidney. 2. In addition, there were 7 bowel and/or mesentericlaceration, 2 diaphragmatic hernia, and 1 urethral rupture. 3. 2 cases fo retroperitoneal hematoma and 1 case inwhich hemoperitoneum occurred without abdominal organ injury were confirmed by follow-up CT or ultrasonography. 4.In all of the 4 patients with multiple organ injury, pancreatic laceration was associated. 5. In abdominal traumapatients, ultrasonography or CT can be used to survey rapidly the entire abdomen for possible associated injury,and be of great help to clinicians in identifying the patients who need immediate surgery or in minimizing theincidence of unnecessary emergency abdominal exploration.

The etiologic factors causing low back pain are numerous and variable. Orthopaedic sugreons tend to focus attention to any defects of structural and functional origins such as pine, discs and facet joints. Clinically, however, the fact remains that not all abnormal findings produce back pain and vice vera. Among the many modalities of investigation to determine the etiology of back pain, plain X-ray of the lumbosacral spine is the single most important acreening method. In addition to antero-posterior, lateral and oblique views, stress view of the spine gives certain clue to predict the disc degeneration. The X-ray findings of a total of 503 patients with low back pain (the study group). admitted during the year of 1977 to the Department of Orthopaedic Surgery, National Medical Center, were reviewed and compared with the control group of 100 patients without relevance to back pain (the control group). Our intention was to explore the relationship between the abnormal findings of plain X-rays and occurence of back pain. and to further entrance the diagnostic value of the spine. The study group of 503 patients (86 cases of which were operated on) were diagnosed not only by routine plain X-rays but also by contrast myelography and tomography in addition to detailed physical examination. Following observations were made: 1. The sex was nearly equally distributed in the atudy group of 503 patients. The age ranged from the second to the eighth decade, dominant group being the third to fifth decades. 2. The causes of the low back pain were herniated disc, spondylosis, spondylolysis, and infection, in that order. 119 patients (23.7%) out of the 503 showed no roentgenologicaI abnormal findings. 3. 384 cases out of the 503 revealed abnormal findings, mainly congenital or developmental and degenerative changes in that order. 4. In a comparative study with the control group, congenital or developmental anomalies and degenerative changes were not related to low back pain. Disc. space narrowing, supposed to be valuable in establishing the diagnosis of low back pain was present in 26% of the cases in study group and in 11% in the control group. 5. The age incidence of the low back pain with congenital or developmental anomalies was mainly in th second and third decades, while that of disc space narrowing was in the third to fifth decade. The degenerative changes of the spine appeared after the fourth decade. 6. Transitional vertebra and tropism are supposed to plsy a role on the degenerative change of the spine. 7. The stress study of the spine had some benifit it the diagnosis of disc degeneration. The mobility of the L4-5 lesion with low back pain was increased to mean 15.1 and standard deviation 3.7, in comparison to the mean 12.3 and standard deviation 3.7 in the control group.
