Pancoast syndrome (PS) is characterized by a malignant neoplasm of the superior sulcus of the lung with destructive lesions of the thoracic inlet and involvement of the brachial plexus and cervical sympathetic nerves. The most common initial symptom of PS is shoulder pain; however, cough, dyspnea, and hemoptysis, signs often associated with lung cancer, are not as common. Investigation of PS can be difficult even with plain radiographs of the chest because it is surrounded by osseous structures such as the ribs, vertebral bodies, and manubrium. Due to these characteristics, orthopedic surgeons tend to make a misdiagnosis resulting in delay of appropriate treatment. Here we report on a patient who was supposed to undergo rotator cuff repair for his shoulder pain and weakness, and was eventually diagnosed with PS.

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.

BACKGROUND AND OBJECTIVES: Primary percutaneous coronary intervention (PCI) has been reported to be effective reperfusion therapy for acute myocardial infarction (AMI). In the very thrombotic environment of AMI, primary PCI, with heparin-coated stents, has been known to reduce the early reocclusion of the stented vessel by preventing thrombosis. However, little data exist regarding the long-term clinical outcomes. The aim of our study was to evaluate the safety, feasibility and long-term efficacy of heparin-coated stents in AMI. SUBJECTS AND METHODS: Between January 1998 and July 2002, primary PCI with heparin-coated stents was performed in 132 consecutive patients (98 males, with a mean age of 56.3+/-0.7 years) admitted with the diagnosis of AMI within 12 hours from the onset of the chest pain. Major adverse cardiac events (MACE), including death, MI, TLR (target lesion revascularization) and CABG, were recorded during hospitalization and the follow-up period. Angiograms were obtained at the baseline, after stent implantation and at 6 months following implantation. RESULTS: The angiographic and procedure success rate was 96.2%. During hospitalization, there was no evidence of reocclusion of stented vessel, but 1 patient underwent a repeat PCI due to dissection. There were no bleeding complications. A six-month angiographic follow-up was completed in 47.2% of eligible patients and binary restenosis was present in 20.1%. During the long-term clinical follow-up (mean follow-up period 37.2+/-7.2 months), there were 12 deaths, 1 myocardial infarction and 18 TLR. The MACE free survival rate was 76.5%. CONCLUSION: Primary PCI, with heparin-coated stents, shows favorable long-term clinical outcomes.

PURPOSE: We have tried to search all concerning data on the policies of hepatitis B vaccination or surveillance of medical equipments that can transmit blood mediated diseases, including disposable syringe, in Republic of Korea, to propose references to other medical professionals. METHODS: Data from domestic journals, government websites, computerized newspapers, etc. were reviewed. The data were arranged into four categories (governmental policies on hepatitis B control, hepatitis B mass immunization program in school, using process of hepatitis B vaccine, and policies on medical equipments surveillance, including disposable syringes, which is considered as source of blood mediated infection), and the periodic changes on each subjects in policies were reviewed. RESULTS: Due to growing social concerns on hepatitis B in early 1980s, swift introduction and production of hepatitis B vaccine was made. After establishment of "5 year project for eradication of hepatitis B" in late 1983, number of vaccinated population jumped up to 6 million within 2 years (1984-85). However, since the immunization targets were mainly adult, not infant, this project was annulled in late 1985. Following this project, hepatitis B mass immunization program in school was carried out. In year 1995, hepatitis B vaccine was included in national immunization program. The use of disposable syringe was recommended from year 1980 but legislated in year 1985, finally. CONCLUSION: The mainstay in controlling hepatitis B in Republic of Korea was coordination of prompt introduction of vaccine, mass immunization, high vaccination coverage rate, or use of disposable syringes. However, since there is lack of official data available, it is urgent to arrange and computerize all government data related to infectious diseases.
