  • Recognition of liability for damages due to medical malpractice has been developed largely on the basis of two paths. First is the case where there is an error in a physician's medical practice and this infringes upon the legal interests of life and body, and the compensation for monetary and non-monetary damages incurred from such infringement on life and body becomes an issue. Second is the case where there is a breach of a physician's duty of explanation that results in a infringement on the patient's right of autonomous decision, and the compensation for non-monetary damages incurred from such infringement becomes an issue. However, even if there is a medical error, since it is difficult to prove the causation between the medical error of a physician and the infringement upon legal interests, the physician's responsibility for damage compensation is denied in some cases. Consider, for example, a case where a patient is already in the final stage of cancer and has a very low possibility of a complete recovery even if proper treatment is received from the physician. Here, it is not appropriate to refuse recognition of any damage compensation based on the reason that the possibility of the patient dying is very high even in the absence of a medical error. This is so because, at minimum, non-monetary damage such as psychological suffering is incurred due to the physician's medical error. In such a case, our courts recognize on an exceptional basis consolation money compensation for losing the chance to receive proper treatment. However, since the theoretical system has not been established in minutiae, what comes under the benefit and protection of the law is not clearly explicated. The recent discourse on compensating for damages incurred by patients, even when the causation between the physician's medical error and infringement upon the legal interests of life and body is denied, by establishing a new legal interest is based on the "legal principle of loss of opportunity for treatment." On what should be the substance of the new legal interest, treatment possibility argument, expectation infringement argument, considerable degree of survival possibility infringement argument and loss of opportunity for treatment argument are being put forth. It is reasonable to see the substance of this protected legal interest as "the benefit of receiving treatment appropriate to the medical standard" according to the loss of opportunity for treatment argument. The above benefit to the patient is a value inherent to human dignity that should not be infringed upon or obstructed by anyone, and at the same time, it is a basic desire regarding life and a benefit worthy of protection by law. In this regard, "the benefit of receiving treatment appropriate to the medical standard" can be made concrete as one of the general personal rights related to psychological legal interest.

  • Hemoptysis which is comparatively common symptom in respiratory disease patients is a clinical symptom which has high risk of death in spite of many curative means. Bronchial tube embolization is a very useful medical procedure when hemoptysis does not stop for treatment of internal medicine or surgery and in addition to the purpose of instant hemostasis, for patients for whom surgical operation is impossible or for the purpose of gaining time to improve the state of the patient before surgical operation. In relation to this, this study is to know of the usefulness of bronchial tube artery embolization. The objects were 60 persons for whom bronchial tube artery embolizations are conducted because of large hemoptysis occurred from March 2007 to December 2009 in J hospital. They had large hemoptysis of 400ml or more per day and 200ml or more at a time or though the quantity of hemoptysis was less than 400ml they did not respond to the treatment of internal medicine for 10 days or longer. The average age was 60.5 years and cause diseases were tuberculosis, bronchiectasis, and pneumonia and lung cancer. Embolus parts were Rt bronchial artery 19 examples, Lt bronchial artery, both bronchial artery, Rt Intercostobronchial artery, and they were the case where embolization for many blood vessels were simultaneously carried out. As embolus materials, PVA (conteour) and microcoil were used. In 76.6% of 60 persons of patients hemorrhage stopped with the lapse of time after the procedure and in 4 examples (6.6) re-embolization was carried out due to re-bleeding after the procedure. Bronchial tube artery embolization has high early success rate and effectively controls hemoptysis in the treatment of hemoptysis and is an effective emergency remedy for hemorrhage due to large hemoptysis and will be a good medical procedure which reduces death rate. In addition, primarily if it is conducted together with the treatment of internal medicine it will be, as an effective curative means for hemorrhage due to large hemoptysis, a good mediate radial rays medical procedure which reduces death rate.

  • Currently, about 35 cyclotrons have been operating in South Korea. Most of them are mainly used for the synthesis of radiopharmaceuticals such as $^{18}FDG$, which is a cancer tracer for nuclear medicine. Highly enriched $H_2{^{18}}O$ containing up to 98% of $^{18}O/O$ isotope ratio is used as the target for $^{18}F$ production. The price of the highly enriched $H_2{^{18}}O$ ranges 60~70 USD/g, and all of them have been imported from foreign country in spite of the very expensive price. The target (enriched $H_2{^{18}}O$) is non-radioactive before the proton beam irradiation. But, the post-irradiation target (used $H_2{^{18}}O$) must be managed following the National Radiation Safety Regulations, because it turns into radioactive by the radioactivation of the impurities within the target. Recently, nevertheless of the fast increasing amount of used $H_2{^{18}}O$ in accordance with the increasing number of nuclear medicine cases, any activation analysis on the used $H_2{^{18}}O$ have been conducted yet in Korea. In this research, activation analysis have been conducted to confirm the specific radioactivity(Bq/g) of each radioisotopes within the used $H_2{^{18}}O$. The analysis have been done on the 3 of 20g samples collected from the used $H_2{^{18}}O$ storages at different cyclotron centers. Based on the results, it was confirmed that the "used $H_2{^{18}}O$" contains gamma emitters such as $^{56}Co$, $^{57}Co$, $^{58}Co$, and $^{54}Mn$ as well as the considerable amount of beta emitter $^3H$. It was also confirmed that the only one sample contained over exemption level of gamma emitters while the specific activity of tritium was lower than the exemption level in all samples. The specific activity of radioisotopes were measured different levels in the samples depending on the elapsed time after irradiation. Further study on the activation of the "used $H_2{^{18}}O$" is definitely necessary, nevertheless the as-is results of this research must be useful in establishing a rational "used $H_2{^{18}}O$" management protocol.

  • Purpose : To characterize the epidemiology and clinical features of invasive pneumococcal infections in Korean children. Methods : One hundred ninety four cases of invasive pneumococcal infections diagnosed at the Seoul National University Children's Hospital from October 1985 to December 2003 were analysed retrospectively. All isolates were screened for resistance to penicillin by oxacillin disc diffusion test. Serotypes were determined for 125 isolates. Results : The types of infection were bacteremia without focus 84/194(43%), meningitis 36/194(19%), pneumonia with bacteremia 36/194(19%), peritonitis 24/194(12%), other focal infections 3/194(2%). Fifty seven percent(110/194) of the episodes developed in the immunocompromised and 20%(37/194) were nosocomially acquired. The patients younger than 2 years of age was 60% in the immunocompetent patients and 25% in the immunocompromised patients. The overall case fatality rate was 7%. All the isolates by 1988 were susceptible to penicillin screened by oxacillin disk. Penicillin resistance was first detected in 1989(20%), and then increased rapidly; 89% in 1995, 69% in 1996, and 80~100% thereafter. The seven most frequently isolated serotypes were 23F, 19F, 14, 6B, 6A, 9V and 19A, which accounted for 70% of total isolates. Conclusion : S. pneumoniaeis an important cause of morbidity and mortality in children. Invasive infections caused by S. pneumoniae most often occurred in infants and young children, while they are frequent in older immunocompromised children as well. This is the largest case series on invasive pneumococcal infections in Korean children.

  • In September 1994, residents of Gozan-dong, Incheon City, made a petition to the government about their health problems which might be caused by previous glass fibre landfill nearby 'H' company. In february 1995, at regular academic meeting of occupational and environmental medicine, a research team of 'D' University presented that they had found glass fibres in groundwater of the area through their survey. They were suspicious of probable association between ingestion of groundwater contaminated with glass fibres and skin tumors among residents. A joint research team was formed and carried out the survey of environment concerning groundwater and its glass fibre existence, and health assessment of residents in the area and industrial workers of 'H' company during May to November, 1995. Analysis of groundwater flow system indicates that the flow lines from the glass fibre landfill pass through or terminate at the 6 houses around the landfill. This means that the groundwater of the 6 houses around the glass fibre landfill could be affected by some possible contaminants from the landfill, but the groundwater quality of the other houses was irrelevant to the landfill. The qualitative and qualitative analyses for glass fibres in 54 groundwater samples including those from the nearby 6 houses, were carried out using SEM equipped with EDS, resulting in no evidence for the presence of glass fibres in the waters. Major precipitates, formed in waters while boiling, were identified as calcium carbonates, in particulary, aragonites in needle form. The results of health assessments of 889 residents in Gozan-dong, participated in this study, showed statistically significant differences in past medical histories of skin tumor and respiratory disease between the exposed group (31 persons who inhabited in 6 houses around the landfill) and the control group, but no significant differences in past medical histories of other diseases, such as cancer mortality, current gastroscopic findings, current skin diseases and respiratory diseases, etc. Also, we could not prove any glass fibres in excised specimens of 9 skin tumors in both groups and there were no health problems possibly associated with glass fibres in employees of the 'H' company. After all, we could not authenticate the association, raised by prior investigators, between groundwater streams, assumedly contaminated with glass fibres or not, and specific disease morbidities or common disease/symptom prevalences. That is, we could not find any glass fibres in groundwater as the only exposure factor of this study hypothesis, and there were not enough certain evidences such as increasing disease prevalences, for examples, skin, respiratory and gastrointestinal diseases etc, possibly related to glass fibre exposure, in exposed group. As a matter of course, the conditions for confirming causal association, for example, strength of the association, consistency of the association, specificity of the association, temporality of the association and dose-response relationship etc, have not been satisfied. In conclusion, we were not able to certify the hypothesis that contamination of groundwater with glass fibres might cause any hazardous health effects in residents who used it for drinking.

  • Among chemical agents in herbicides, dioxin (2, 3, 7, 8-tetrachloro dibenzo-$\rho$-dioxin : TCDD), a chemical contaminant in herbicides sprayed during the Vietnam War has been known to be the major agent causing toxic effects. Approximately 320,000 korean soldiers participated the Vietnam War from 1964 to 1974. Although the potential hazards of the herbicides among Korean veterans exposed were implicated, the problem had not been a public issue until 1991 when Korean veterans were informed U.S. companies, the herbicides manufacturer payed fund, from which a trust fund for New Zealand and Australian Class members were established in 1985. After a series of appeals and demonstration by the Korean Veterans demanding medical care and compensation for their serious health damages, a bill of medical care and compensation for herbicides victims was promulgated in March 1993 and become effective from May 1993, This study was carried out with two major objectives : the first to understand the health problems caused from the herbicides by reviewing literatures published, and the second to examine the nature and extent of health impacts among Korean veterans exposed and to develop valid study methods for the major study by interviewing and reviewing records on a part of veterans (638 persons) registered and completed medical examination in Seoul Veterans Administration Hospital from June to October 1993. The results obtained are as followings: 1. The literature review of 107 papers revealed that 1) Dioxin is teratogenic, carcinogenic and affects almost all organs including nervous, endocrine, and reproductive systems in animal experiments. 2) The diseases showing evidence of causal association were Hodgkin's disease, non-Hodgkin's disease, lung cancer, lymphoma, soft tissue sarcoma, chloroacne and polyneuropathy when judged on the basis of consistency in study results and biological plausibility. 2. Interview and medical record review study on 638 veterans, though limited validity owing to lack of control group, crude estimates of dioxin exposure levels (no biomarkers measurable), and uncertainty of diagnosis, showed that: 1) Most of the study subject's were in their 40's of age and had been dispatched to Vietnam during the period from $1965{\sim}1970$ around one year. 2) Most frequently complained symptoms in medical examination were motor weakness (32%), sensory abnormalities in extremities (23%), skin diseases (22%), and pain in extremities (20%) whereas in Interview they were more frequent in order of skin problem (44%), motor weakness (38%), sensory abnormalities and pain in extremities(17% and 19% each). Kappa indices on the same category of complaints between two sources of information were variable and relatively low. 3) On medical examination, only a part of the 638 subjects had initial impression (442 pts) and final diagnosis (218 pts) suggesting decision making on diagnosis appeared to be difficult even with all available modern medical technologies: in initial impression disorders from peripheral and central neuropathy were predominant whereas in final diagnosis various types of skin disorder were most frequent 4) When dose-response relationship between several conditions (from questionnaire) and arbitrary exposure scores were examined by CMH linear trend test, spontaneous abortion, sexual problems and health problem of offsprings showed statistically significant linear trends. However, pregnancy, accident and suicidal attempts did not show any relationship in this study capacity. 5) Among complaints, psychosis and neurosis (anxiety, phobia) in interview study, and memory disorder and psychosis in medical record study revealed linear trend. 6) Skin disorder was the only condition showing linear trend in initial impression and none in final diagnosis on medical examination. Even though objective to select out dioxin-related disease or group of diseases from this study was not achieved the research experiences provided firm basis for developing various methodological approaches. 3. From this preliminary study we concluded that a larger scale major epidemiologic study on health impacts of herbicides among Korean veterans exposed is not only Indispensible but also well designed study with more valid exposure information and diagnosis may be able to establish causal relationship between certain groups of diseases and exposure to the herbicides among Korean veterans.

  • Objectives: The authors conducted the study to evaluate bias when potentially diseased subjects were included in cohort members while analyzing risk factors of chronic liver diseases. Methods: Total of 14,529 subjects were followed up for the incidence of liver diseases from January 1993 to June 1997. We have used databases of insurance company with medical records, cancer registry, and death certificate data to identify 102 incident cases. The cohort members were classified into potentially diseased group(n=2,217) when they were HBsAg positive, serum GPT levels higher than 40 units, or had or has liver diseases in baseline surveys. Cox's model were used for potentially diseased group, other members, and total subjects, respectively. Results: The risk factors profiles were similar for total and potentially diseased subjects: HBsAg positivity, history of acute liver disease, and recent quittance of smoking or drinking increased the risk. while intake of pork and coffee decreased it. For the potentially diseased, obesity showed marginally significant protective effect. Analysis of subjects excluding the potentially diseased showed distinct profiles: obesity increased the risk, while quitting smoking or drinking had no association. For these intake of raw liver or processed fish or soybean paste stew increased risk; HBsAg positivity, higher levels of liver enzymes and history of acute liver diseases increased the risk. Conclusions: The results suggested the potential bias in risk ratio estimates when potentially diseased subjects were included in cohort study on chronic liver diseases, especially for lifestyles possibly modified after disease onset. The analytic strategy excluding potentially diseased subjects was considered appropriate for identifying risk factors for chronic liver diseases.

  • Purpose : To clarify the clinical benefit derived from the combined modality therapy (CMT) consisting of chemotherapy (CT) and involved field radiotherapy (RT) for stage I and II angiocentric lymphomas of the head and neck. Materials and Methods : Of 143 patients with angiocentric lymphoma of the head and neck treated at our hospital between 1976 and 1995, 104 patients (RT group) received involved field RT alone with a median dose of 50.4 Gy (range : 20~70 Gy), while 39 patients (CMT group) received a median 3 cycles (range : 1~6 cycles) of CT before involved field RT. The response rate, patterns of failure, complications, and survival data of the RT group were compared with those of the CMT group. Results : Despite a higher response rate, local failure was the most common pattern of failure in patients of both groups. The patterns of failure, including the systemic relapse rate were not influenced by the addition of combination CT. Although both modalities were well tolerated by the majority of patients, aberrant immunologic disorders or medical illnesses, such as a hemophagocytic syndrome, sepsis, intractable hemorrhage, or the evolution of second primary malignancies were more frequently observed in patients of the CMT group. The prognosis of patients in the RT group was relatively poor, with a 5-year overall actuarial survival rate of 38% and disease-free survival rate of 32%, respectively. However, their clinical outcome was not altered by the addition of systemic CT. Achieving complete remission was the most important prognostic factor by univariate and multivariate analyses, but treatment modality was not found to be a prognostic variable influencing survival. Conclusions : Involved field RT alone for angiocentric lymphoma of the head and neck was insufficient to achieve an improved survival rate, but the addition of CT to involved field RT failed to demonstrate any therapeutic advantage over involved field RT alone.

  • Locally advanced cervical carcinoma has shown high rate of local failure and poor survival rate despite the advances in modern radiation therapy techniques. Combination of chemotherapy and radiation therapy demonstrated benefit in improving local control and possibly the overall survival. Twelve patients with advanced stages (Figo stage III, IV) or 11b with bulky tumors (>5 cm in diameter) were treated with combination of radiation therapy and concurrent weekly cisplatin between May of 1988 and September of 1991 at Inje University Paik Hospital. Cisplatin was administered in bolus injections of 50 mg at weekly intervals during the courses of radiation therapy. Median follow-up period was 34 months with ranges from 3 to 53 months. Eleven patients were evaluable for the estimation of response. Response was noted in all the 11 patients: complete response (CR) in 7 ($64\%$), partial response (PR) in 4 ($36\%$). Of the 7 patients with CR, all maintained local control, whereas only 1 of 4 with PR showed local control. Six of 7 with CR are alive disease free on the completion of follow-up. Eight of 11 patients ($73\%$) maintained local control in the pelvis. The median survival for CR patient is 27 months and 9 months for the PR patients. Analysis of survival by stage shows 11 b 4/5, III 2/3 and IV 1/3. Overall survival rate was $61\%$. Three patients recurred: 1 at local, 1 in distant site and 1 with local and distant site. Toxicity for the combination therapy was not excessive. These results are preliminary, but definitely encouraging in view of markedly improved response rate compared with the results of historical control group.

  • Purpose: This study was performed to examine the neck failure patterns after a complete response (CR) to definitive radiotherapy for advanced head and neck cancer patients, as well as evaluate the clinical significance of the results of this study. Materials and Methods: Between 1987 and 2008, the clinical data of patients who had been treated with radical radiotherapy for primary squamous cell carcinomas and enlarged cervical lymph nodes was analyzed retrospectively. Ultimately, the cases that showed CR of the cervical lymph node lesions to full-dose radiotherapy were included in this study. The recurrent rate and sites in the cervical lymphatic area were evaluated periodically by radiologic imaging studies, along with some factors which might have affected the rate of recurrence. Results: A total of 73 patients who achieved CR in neck area after radiotherapy were included in this study. The rate of subsequent neck failure among those patients was 19.2%. There was only a 5.5% failure rate in the 55 patients who underwent radiotherapy in their primary site. Eighty percent of the recurrent cases were found within 3 years (median follow-up, 68 months). The majority of neck recurrent cases (47%) were accompanied with the failure of the primary lesions. The initial response of the primary site and the method of radiotherapy simulation were significant prognostic factors associated with the nodal recurrence rate. Conclusion: The recurrence rate of cervical nodes in patients with CR to radiotherapy in the primary site and neck area was about 5%. These patients could be followed up with close observation without a planned neck dissection.
