Through the whole history of medicine, there runs a long struggle between two principal tendencies-empiricism and rationalism. The empirical trend lays its emphasis on "experience" for the cure of the sick. The rationalistic trend lays its main emphasis on "mechanism" for the causes of diseases. The term "evidence-based medicine (EBM) ", defined as "the conscious, explicit and judicious use of the best current evidence in making decisions about the individual patients", was introduced about ten years ago. The proponents has been described EBM as a "paradigm shift" that will change medical practice in the years ahead. But there has been considerable debate about the value of EBM. The modern medicine, following philosophy of modern science such as the 'realism controlled by empiricism', has developed biomedical model. But the EBM wrapped with clinical epidemiology and statistics, represents response of empiricism to the rationalism (realism). The roots of EBM extend back at least as far as the Paris clinical school, and the work of Pierre Louis in Paris in the early 19th century. Is EBM a paradigm shift? To answer this question, We have to specify the alternative with which we are comparing EBM. The alternative to EBM is the basic science approach: studying the pathophysiolological mechanism of the body. But EBM is so clearly intertwined with and complementary to the basic science that it would make little sense to see EBM as a paradigm shift away from basic science. In a sense, evidence-based medicine shows only methodological contribution aimed at improving the gathering and sorting of the best information published by biomedical scientists and clinical epidemiologists for use in clinical practice. Although EBM and the traditional medicine embody different approaches, this does not mean that they are competitors. In fact, the two approach need each; neither can stand alone for the development of clinical practice.

Not only disease patterns but also the contents and concepts of medical services are rapidly changing recent years. A quick look at the evolution of health care services shows that it has evolved in two major ways. First, medical interventions are gradually moving towards the prevention before diseases development. Second, the medical services have become individualized or tailored. The shift to preventive medical care is the most anticipated change in medical services in the 21st century. Theses phenomena are believed as a logical progression in the transition and evolution of medical services, and as a equivalence of the changing medical environment, such as progress in health care technology and changes in life value etc. Clinical practice based on evidence-based medicine is what distinguishes modern medicine from traditional medicine. Preventive medical services have also been established based on scientific evidence. The academic knowledge used as a basis for preventive medical services comes from the investigation of disease etiology, i.e. epidemiology. In the 21st century, the preventive medical service will be differentiated and enlarged to broad areas of medical practice and the target of the service may be focused to the a variety of complex diseases.

BACKGROUND: The purpose of this study was 1) to review the length of an adequate period of conservative treatment and the appropriate surgical indications for herniated lumbar disc(HLD), 2) to collate the scientific evidences on surgeries for HLD, and 3) to collect expert opinions on HLD. METHODS: We searched for articles in PubMed, the Cochrane Library and KoreaMed up to 1 October 2008, and these articles were concerned with the natural history of HDL, systemic reviews of HDL and expert opinions on HLD. We also searched for meta-analyses and randomized or quasi-randomized controlled trials(RCTs or QRCTs) of surgery for HLD. We performed a meta-analysis using the Cochrane method. The survey consisting of 21 questions was delivered to all the members of the Korean Spinal Neurosurgery Society(KSNS) via E-mail. RESULTS: A total of 59 articles were included in this study. There were 16 articles concerning the period of conservative management and the surgical indications. Among the 33 articles on surgery for HLD, there were 4 meta-analyses, 27 RCTs, and 2 QRCTs. Among the 938 members of the KSNS, 72 responded to the survey. A minimum of 1 to 3 months of conservative management was the most preferred answer(58%), followed by a conservative management period of less than 1 month(33%). Percutaneous endoscopic discectomy was more preferred by the hospitals that specialized in spinetreatment than by the university hospitals(p<0.05). CONCLUSION: Conservative management for a minimum of 2 weeks to 3 months is recommended for patients with tolerable pain only. The patients with neurological compromise or intolerable pain should be considered for surgery. There is strong evidence on the relative effectiveness of surgical discectomy versus chemonucleolysis versus placebo. There is no scientific evidence on the effectiveness of any other form of minimally invasive procedure.

Translational research (TR) can be defined as research where a discovery made in the laboratory (bench) can be applied in the diagnosis, treatment or prevention of a disease. Examples of medical discoveries contributing to translational medicine (TM) include the isolation of insulin by Banting (Nobel Laureate, 1923), the discovery of penicillin by Alexander Fleming (Nobel Laureate, 1945) and recently the discovery of the role of bacterium Helicobacter pylori in the causation of gastritis and peptic ulcer by Marshall and Warren (Nobel Laureates, 2005). Clinical research (CR) would be a more appropriate term for the bulk of research work undertaken by doctors. CR embraces both clinical based and laboratory-based research. The terminology "bedside to bench" applies more to CR as opposed to "bench to bedside" in the case of TR. But regardless of who does it, as long as the discovery can be translated to the bedside and results in improvement in patient care it can be considered a contribution to TM. Our work spans a 30-year period, involving laboratory-based research, clinical trials and genomics of IgA nephritis (Nx). This is a series of work to elucidate the pathogensis and therapy of IgANx. Plasma beta-thromboglobulin (BTG) an in-vivo index of platelet aggregation and anti-thrombin III increase due to a constant thrombogenecity resulting from platelet degranulation formed the basis for anti-platelet and low-dose warfarin therapy. A study of the natural history of IgANx revealed 2 courses, a slowly progressive course with end-stage renal failure (ESRF) at 7.7 years and a more rapid course at 3.3 years. Triple therapy (cyclophosphamide, persantin and low-dose warfarin) delayed progression to ESRF by about 8 years and for some patients up to 20 years. Documentation of abnormal suppressor T cell function provided the basis for immune therapy. Four patterns of proteinuria were present in IgANx and it is the quality and not so much the quantity of proteinuria which determined the prognosis. Low molecular weight proteinuria was a bad prognostic marker. A controlled therapeutic trial using ACEI/ATRA showed that therapy decreases proteinuria, improves renal function and converts non-selective to selective proteinuria. Subsequent work confirmed that it was the ATRA, not the ACEI which contributed to improved renal function. Individual anti proteinuria response to ATRA varies depending on ACE gene polymorphism. We found that the II genotype of the ACE gene was renoprotective and patients with this genotype had significantly reduced incidence of ESRF compared to those with the DD genotype. Patients responsive to ATRA therapy can retard progression to ESRF by up to 32 years. Mild renal failure can be reversed with possible regression of glomerulosclerosis because of glomerular remodelling by ATRA.

Due to technological advances and the establishment of evidence-based medicine, radiological examinations are playing a crucial role in modern medicine, as a result of which they have been steadily increasing, and the rate of increase has intensified in the 2000s. Although this is a global phenomenon, the increase of radiological examinations in Korea is also high due to the introduction of the National Health Insurance Coverage Expansion Policy, so-called Moon Jae-in Care, for ultrasonography and magnetic resonance imaging. For accurate and rapid diagnosis of diseases, it is necessary for doctors to order appropriate radiological studies. However, the increase in radiological examination has created many problems, such as increased medical costs, decreased diagnostic accuracy due to radiologist burnout, and increased patient exposure to radiation. To reduce unnecessary imaging studies, a number of measures could be deployed including the development of clinical guidelines to select appropriate radiological examinations for each clinical situation.

ImwonGyeongjeji which was created by Seo Yu-gu in the first half of the 19th century is a encyclopedia of practical use in rural life. It consists of 113 volumes, 16 fields, and 2.52 million total characters. Of these, the field of medicine comes 11th of the contents covering 28 volumes and 1.1 million characters. Its name is Inje-ji. This paper examines the academic background of Seo Yu-gu and his life work briefly, and investigates the characteristics of medical knowledge of late Joseon period contained in the Imwon Gyeongjeji / Inje-ji. Here, we made key comparisons especially with Dongui-bogam, Joseon's leading medical book. Of the pioneers of medical history studies of Joseon, a Japanese researcher Miki Sakae has made a negative evaluation to Inje-ji. But after concrete investigation we have come to conclude as follows. First, familial ancestors of Seo Yu-gu were engaged in the introduction of foreign-language books, so Seo Yu-gu as a officer of proof-reading and editing of the various books, also had a lot of knowledge on the medical books ever in history. On this background and experience, for over 36 years from 1806 retirement from official position to his death, he had compiled and edited Imwon Gyeongjeji. Second, unlike Dongui-bogam which included improving health skill, Inje-ji focused on curing medicine readily accessible from the major population of that time. Its main features are as follows: i) prescriptions directly linked to the diseases and symptoms, ii) greatly increased medicinal knowledge especially on infectious diseases and trauma, iii) detailed index easy to look up for prescription and iv) his 'own opinions'[an-seol] which can indicate relevant contents within the book and organically combines the whole knowledge in it. Third, "Inje-ji" utilizing medical books in China and Korea even those of Japan, collected more massively almost all the medical knowledge, new illness, herbs of local area, private prescription. Meanwhile Inje-ji modified the errors of the older medical books like Dongui Bogam or Bencao Gangmu, expressed its own subjective views about controversial topics. In summary "Inje-ji" can be the last general medical book which collected and edited almost all the medical knowledge of the period in the East Asia with its own editing format. In addition it is recognized that it pursued an evidence-based medicine and the practical medicine relieving the people, rather than medico-philosophical theories in oriental traditional medicine which was criticized by many critical intellectuals afterwards. Given the scrutiny, it seems that evaluation of the "Inje-ji" by Miki Sakae should be revised by thorough investigations. We are just on the starting line of the Inje-ji research in earnest meaning, and expect this research would give more fruitful and deep perspective in the area of Korea history of medicine.
