AIMS: This study was done to develop an ethical guideline for organ transplatation, a life-saving treatment which helps improve the quality of life. METHODS: This study begins with a survey of the Korean current state of affairs concerning organ transplantation. This study used a survey questionnaire and received responses from 31 hospitals out of 45 hospitals where organ transplantation are being done. After this survey, followed by a discussion of ethical considerations in arranging organ transplants. Before proposing an ethical guideline, this study discusses a series of interesting ethical issues in transplanting(both living and cadaveric)organs including ethical foundations of organ transplantation, distributive justice and matters of donor's consent in organ transplatation. RESULTS: The foremost research for this study boils down to a survey paper titled, "An Analysis of the Current State of Affairs Concerning Organ Transplantation and Ethical Considerations in Domestic and International Hospitals." Based upon data collected from various hospitals, this work analyzes items, such as the frequency and types of organs transplanted in a hospital, the existence of organ transplant coordinator, the performance of the hospital ethics committee, and ethical considerations in obtaining consents from the living donor. Although thousands of organs are annually transplanted in domestic hospitals, virtually none of them are found to meet ethically proper standards. The paper points out the need to institutionalize a nationwide cadaveric organ distribution organization like UNOS(United Network for Organ Sharing) in the U.S., and proposes to stretch out the national health insurance to extensively cover transplanting expenses. "The Ethical Foundation of Organ Transplantation", the author counts three key ethical principles in organ transplantation: the principle of respect for autonomy; the principle of beneficence; and the principle of justice. He argues that in cases of living donor no principle should take precedence over the principle of respect for autonomy and thus it is very important for a hospital to obtain the donor's consent. As for cadaveric organ transplantation, he holds reservation because he is worried that serious shortage of organs for transplantation in conjunction with pure utilitarian considerations could change the definition of death so that the brain death gains more popularity than ever. In addition, the author claims that the proponent of organ transplantation must distinguish the moral dimension of the discussion from the legal one because otherwise she would hardly be able to defend herself from the slippery slope argument against organ transplantation. This paper concludes with a note that we must implement restrictions to avoid undesired effects if organ transplantation could ever be justified. "A Discussion of Distributive Justice in Organ Transplantation" comprises two parts. The first half delineates above mentioned ethical principles in the context of organ transplantation, while the second half goes generally over the UNOS Point System. This work is focused entirely upon cadaveric organ transplants, because the vast majority of organs available for transplants comes from cadavers and the number is still increasing. The UNOS allocates cadaveric organs based upon both medical and justice criteria. Following are summaries of the UNOS policy on organ distribution. Every potential recipient of organ transplants must be listed on the UNOS computer system waiting list. Allocation of cadaveric kidneys consider factors such as waiting time, six antigen match, panel reactive antibody, blood group and age. The UNOS Point System allocates livers to the local patients first, followed by regional and national patients respectively, in order to limit ischemic time. A recipient of liver transplant belongs to one of five(0~4) medical status levels where status 4 is the most medically urgent. At the regional and national levels pancreas are allocated first to patients with excellent HLA matches, while at the local level waiting time is the sole factor. The intestinal organ allocation system is based on two(1~2) patient status codes, ABO blood type identity and time waiting. In heart or lung tranplants ischemic time seriously matters. "A Biomedical Study of Informed Consent from the Organ Donor" investigates several topics: the relevance of the principle of respect for autonomy as the basic principle of informed consent; how the autonomy of the organ donor to be respected; and the role of the hospital ethics committee in obtaining informed consent from the donor. The author finds the principle of respect for patient's autonomy not sufficient for the basic principle of the living donor's informed consent because there is some danger in which the patient may be left uncared-for, and thus she suggests that the principle of nonmaleficence and the principle of care also be considered. That the principle of respect for autonomy turns out not sufficient even for cadaveric organ donation, and so judgment based upon the best interest of the deceased may seem appropriate for people from some special groups. A medical team must make efforts to identify the donor's competence and voluntariness, i.e., preconditions of informed consent. All the relevant medical information should be disclosed to the living donor. Once the donor makes a judgment, medical experts should respect the donor's decision. This article puts an emphasis on the role of the hospital ethics committee in such activities as identifying donor's voluntariness, confirming the disclosure, and evaluating the minority's benefit. The last work in this paper, "A Moral Theological Investigation of the Presumed Consent in Organ Transplantation" talk about Principium Riflexum(the principle of reflection) in an attempt to explain the possibility that we may harvest cadaveric organs from the deceased who while alive had never expressed their wishes concerning organ donation. To apply the principle in the context of presumed consent, the author, a Catholic priest, introduces two elements of the principle. Probabilismus allows us to feel free to choose when we face dubious matters(in dubio libetas), and by the rule of selection we are justified in choosing whatever our consciousness mandates. He takes both elements to support the presumed consent of the deceased because he believes the good that people may contribute to their neighbors by donating organs would obviously override opposing reasons. Although the author argues for the presumed consent from the deceased, he does not overlook the family grief in donating the cadaveric organs. He concludes with a suggestion that we should work to keep the public aware of cadaveric organ donation and to form public opinions education should play a key role. CONCLUSION: Researcher suggest an Ethical Guideline for Organ Transplantation as our study conclusion. 1) Body organs may be transplanted to protect the health and well-being of the patient, but not for the medical or scientific research. 2) Body organs may be taken for transplantation, only with the consent from the donor. In cases of cadaveric donors who have left no formal consent in the lifetime, they are to be presumed to refuse to donate body organs. 3) In principle, cadaveric transplantation is preferred. Living donors are limited to competent adults who have blood ties with the patient, e.g., parents, children, or siblings of the patient. However, reversible tissue like bone marrows donation may be an exception to this limitation. In particular, no living donors may be put under inappropriate pressure or influences. Body organs may be taken from the living donor only if based upon sufficient and easy-to-understand information provided, the donor voluntarily consents after (s)he deliberately balances benefits against harm. 4) Under no circumstances human bodies, organs, or tissues may be sold or purchased for transplantation. A physician should not participate in any transplanting operations if (s)he becomes to know that the transplant has been obtained through a transaction. 5) Recipients of organs for transplantation should be determined in accordance with the principle of justice on the allocation of limited medical resources. 6) When a vital, single organ is to be transplanted, the death of the donor shall have been determined by at least one physician other than the recipient's physician. 7) Transplant procedures of body organs should be undertaken (a) only by physicians who possess special medical knowledge and technical competence developed through special training, study, and laboratory experience and practice, and (b) in medical institutions with adequate facilities. 8) All decision procedures in transplanting body organs should be objective, open to parties involved, kept accurately on record, and maintained for a given period of time.

We have reviewed 251 children with urinary tract infection who were seen in our hospital during the last 5 years. Underlying abnormalities of the urinary tract were found in 154 patients(61 %). This figure is high because referred patients from other physicians for further treatment are included here. Of these 154 patients, surgical treatments were required in 85. The most frequent finding was vesicoureteral reflux(110 pts). Obstructive lesions were found in 44 pts ; UPJ obstruction in 9, megaureter in 6, obstruction associated with duplication in 6, urethral valve in 5, neurogenic bladder in 11, and others in 7. Abnormal findings without clinical significance were found in additional 17 pts. To evaluate the role of ultrasonography(US), we have compared findings of intravenous pyelography(IVP) and US. Of 58 pts who had both studies, 52 showed identical findings. US failed in detection of small renal scar and duplication of collecting system. US in combination with voiding cystourethrography(VCU) identified abnormal findings in most cases. It is our impression that US can replace IVP as a screening procedure which should be performed with VCU in every child with proven UTI. And as IVP is superior in imaging anatomical details than US, we recommend IVP before any surgical attempt.

PURPOSE: There are so many causes of an altered mental status, including acute stroke and nonorganic causes. Making the differential diagnosis and the diagnostic approach for cases with an altered mental status represent a challenge to all emergency physicians. The serum S-100B protein concentration and the neuron-specific enolase (NSE) concentration have been used to evaluate brain damaged patients. We evaluated the usefulness of the serum S-100B protein concentration and the NSE concentration as screening tests for the patients with an altered mentality METHODS: Seventy-eight patients with an altered mentality were included in this prospective study. The patients were divided in two groups. One was the acute stroke group and the other was the non-organic cause group. We analyzed the serum S-100B protein and NSE concentrations of the two groups. We also assessed the correlation of the serum S-100B protein and NSE concentrations with the clinical and laboratory data of the two groups RESULTS: The serum concentration of S-100B was higher in the acute stroke group (median: 0.376, interquartile range: 0.18-1.05) than that in the nonorganic group (0.123, 0.087-0.307, p=0.000). The NSE level was also higher in the acute stroke group (median: 19.12, interquartile range: 14.42-27.19) than that in the non-organic group (13.71, 10.48-19.29, p=0.002). To differentiate the acute stroke group from the non-organic group, the sensitivity and specificity was 81.1% and 61.0%, respectively, at a cutoff value for the serum S-100B protein concentration of 0.14 microgram/L, and these were 81.1% and 51.2%, respectively, at a cutoff value for the serum NSE concentration of 13.71 microgram/L CONCLUSION: Our study suggests that the serum S-100B protein and NSE concentrations may be useful as screening markers for differentiating acute stroke from non-organic causes. However, further studies are needed to evaluate the relationship between the two proteins and the various diseases that have possibility to alter patients' mental status before these two proteins can be used clinically as screening tests.

This study was conducted to investigate the association of the occurrence of pediatric disease with environmental, seasonal and atmospheric factors. The data were collected at 5 pediatric clinics in Seoul and the Department of Pediatrics of Yongin Severance Hospital from May 1986 to April 1987. The results were as follows: 1. Vacation periods had a great influence upon the occurrence of pediatric diseases. 2. The majority of pediatric diseases occurred mainly in spring and autumn, not in summer and winter. 3. The higher the average relative humidity was, the less diseases occurred; and the higher the maximum change of daily temperature, the more diseases occurred. 4. In summer, the pattern of diseases varied along with the environmental factors(eg., toilet).

PURPOSE: In Korea, emergency department overcrowding in large hospitals have caused social concern. Moreover, patients with low socioeconomic status visit the emergency department more frequently. This kind of visitation also causes a burden on the national budget, but emergent patient should be treated in emergency department regardless of economic state. So, on establishment of policy about the patient with low socioeconomic status, the frequency of emergency visitation alone is difficult to obtain a sufficient basis for policy-making. METHODS: We retrospectively analyzed adult patients with a disease who visited the Pusan Wide-regional Emergency Center in 2015. Korean Triage and Acuity Scale level I, II or III were defined as emergency, and level IV or V was defined as non-emergency. The ratio of emergency and non-emergency was compared in the National Health Insurance and Medicaid database. RESULTS: The number of patients with National Health Insurance was 16,208 (90.3%) and with Medicaid was 1,737 (9.7%). Among those with National Health Insurance, there were 12,720 (78.5%) emergency cases and 3,488 (21.5%) non-emergency cases. Among those with Medicaid, 1,379 (79.4%) emergency cases and 358 (20.6%) non-emergency cases. Between National Health Insurance and Medicaid, there was no statistically significant difference in the ratio of emergency and non-emergency (p=0.380) CONCLUSION: Accessibility of emergency and non-emergency patients with National Health Insurance and Medicaid to Pusan Wide-regional Emergency Center was not different.

Epstein-Barr virus (EBV)-associated disease is known to be one of the major complication after transplantation. Early identification and diagnosis is crucial. The objectives of this study are to evaluate the incidence and to analyze the risk factors of EBV-associated disease. Twenty-five children with liver transplantation from Oct. 1994 to Oct. 1997 had been surveyed. Laboratory data of EBV infection such as anti-viral capsid antigen (VCA) IgM and IgG, EBV PCR, EBV encoded small RNA (EBER) in situ hybridization had been obtained at pre op, and post op 1, 2, 3, 4, 12, 24 weeks, then annually or when EBV infection was suspected. We classified these cases as asymptomatic infection, EBV syndrome, posttransplant lymphoproliferative disease (PTLD). And we analyzed the incidence of EBV infection according to age, type of immunosuppression, and CMV disease. Incidence of EBV infection in this study was 48% (12 out of 25), among them, 5 children were symptomatic and PTLD developed in 2 children. The significant risk factors were age at transplantation and CMV infection. One of PTLD cases resulting from EBV infection showed fatal outcome, the other was improved. We suggested that physicians especially in the care of the children after the liver transplantation should recognize the risk factors of the development of the EBV infection to avoid the progression into the potentially fatal PTLD.

OBJECTIVES: The purpose of this study was to examine the correlation between exposure to acetone and isopropyl alcohol (IPA) and the acquisition dyschromatopsia. METHODS: A study was performed on exposure group of 116 people exposed to and a group of 36 people not exposed to organic solvents were selected and examined. Their smoking and alcohol habits, symptoms, and exposure history were surveyed through questionnaires and interviews. Then dyschromatopsia was evaluated with the Lanthony D-15 d test in a room with standardized intensity of illumination. RESULTS: The statistical prevalence of dyschromatopsia was significantly higher in the exposed group (30.2%) compared to that found in the control group (19.4%). Out of the 116 subjects in the exposed group, 30 people had acquired dyschromatopsia (25.86%). The variables affecting the color confusion index, such as age, exposure, and the duration of exposure, were statistically significant variables. CONCLUSIONS: He prevalence of dyschromatopsia was found to be not significantly higher in the group with exposure to organic solvents compared to that found in the control group. In addition, a statistically significant correlation was found between exposure to organic solvents and the color confusion index.

Sorafenib is the only approved targeted agent as the first line systemic therapy for treatment of advanced hepatocellular carcinoma (HCC). However, the improvement of survival duration under 3 months is far from clinical satisfactory and most patients experience disease progression within 6 months after sorafenib therapy. Unfortunately, second line systemic therapy after treatment failure of sorafenib was not established and there were no clear guidelines for salvage treatment modalities. Recently, studies suggests that combination of sorafenib and single cytotoxic agent can be relatively effective and safe strategy that achieves promising rates of local and systemic control in advanced HCC patients. Based on above suggestions, we herein offer our experience of a case achieved complete remission by combination therapy of sorafenib and tegafur in the patient with progressed disease after sorafenib therapy.

A gastric carcinoid is a rare disease that accounts for only 0.3% of all primary gastric tumors. It can be multiple or occur with other types of tumor. However, there has been a recent increase in incidence. While carcinoids of the appendix and rectum are accompanied by adenoma or adenocarcinoma, a gastric carcinoid rarely occurs with an adenocarcinoma, particularly with a gastric adenoma. We encountered a case of a gastric adenoma and carcinoid mixed as a composite tumor, which became a lesion. The lesion resembled a type IIc early gastric cancer at the endoscopic examination and was removed by an endoscopic mucosal resection. We report a composite tumor of the gastric antrum composed of areas of adenoma and carcinoid, with an analysis of the histological components by immunohistochemical staining. Microscopically, the lesion was composed of a gastric adenoma and carcinoid as a composite tumor.
