ABSTRACT
Purpose@#In June 2016, the Model for End-Stage Liver Disease (MELD) score was employed in South Korea instead of the Child-Turcotte-Pugh (CTP) score. This study compared the outcomes of deceased donor liver transplantation (DDLT) before and after the MELD system application. @*Methods@#This retrospective study reviewed 48 patients who underwent DDLT for end-stage liver disease at a single tertiary referral center between January 2014 and December 2018. The patients were categorized into the pre-MELD (22 patients) and post-MELD (26 patients) groups. The demographics, postoperative outcomes, and overall survival time were evaluated between the 2 groups. @*Results@#The 2 groups had no differences in age, sex, ABO type, etiology for liver transplantation, CTP-score, operation time, cold ischemic time, and amount of red blood cell transfusion, although their MELD score differed significantly (postMELD group, 36.2 ± 4.9; pre-MELD group, 27.7 ± 11.8; P < 0.001). The post-MELD group has longer intensive care unit stay (11.2 ± 9.5 days vs. 5.7 ± 4.5 days, P = 0.018) and hospital stay than the pre-MELD group (36.8 ± 26 days vs. 22.8 ± 9.3 days, P = 0.016). The 1-year survival rate was lower in the post-MELD group (61.5% vs. 86.4%, P = 0.029). @*Conclusion@#After MELD allocation, patients with high MELD scores had increased DDLT and consequently required a longer recovery time, which could negatively affect survival. According to the experience of a small-volume center, these problems were related to both severe organ shortages in South Korea and MELD allocation.
ABSTRACT
Purpose@#The incidence of poorly differentiated thyroid carcinoma (PDTC) is extremely low among thyroid cancers and there is no standardized treatment guideline for it. In this study, we have analyzed PDTC patients and reviewed their clinicopathological features. @*Methods@#Data of PDTC patients from our institution are collected through the electronic medical database. We analyzed them by several parameters such as basic demographics, presenting symptom, preoperative cytology results, associated pathology, surgical results, surgery type, and distant metastasis. @*Results@#We collected 23 cases in our institution. Apart from two patients who were transferred to another hospital upon diagnosis, all 21 operated cases are analyzed. The parameters we studied were age, sex, presenting symptoms, distant metastasis and pathological features such as tumor size, associated pathology, predominant pattern and so on. We also provided descriptive analyses according to the type of presentation and treatment; patients with distant metastasis, juvenile cancer, and concurrent hyperthyroidism. Furthermore, we provided different cases in which the initial surgical plans differed. @*Conclusion@#We present 21 cases of PDTC patients and clarify their clinicopathological features. Despite some limitations, this study may shed light for future research regarding treatment of PDTC patients.
ABSTRACT
PURPOSE: In this study, doctors were surveyed with a questionnaire to determine whether they performed simultaneous vaccination and whether there were any concerns about safety or anxiety. The purpose of this study was to determine any problems associated with doctors readily performing simultaneous vaccination. METHODS: A trained surveyor visited 241 doctors from every institution registered with the National Immunization Program (NIP) located within six districts (gu) in the City of Busan (Dongnae-gu, Geumjeong-gu, Yeonje-gu, Suyeong-gu, Busanjin-gu, Haeundae-gu); a total of 155 (64%) valid responses were obtained. RESULTS: Of the 155 respondents, 144 (93%) were already performing simultaneous immunizations and 141 (91%) had a positive view of the practice. However, among the 144 doctors performing simultaneous immunizations, 67 (47%) were not confident about its safety; side effects were seen after simultaneous immunization by 86 doctors, 35 (41%) of whom believed that the frequency or possibility of side effects in simultaneous immunizations was higher than that in sequential immunizations. CONCLUSIONS: The use of simultaneous immunization is expanding quickly. However, among the doctors performing simultaneous immunizations, a high percentage had concerns over its unproven safety and potential side effects, indicating the need for academic societies or government institutions to present evidence to address such concerns.

OBJECTIVES: To compare the mortality rate of children under ages five from different countries by their causes and to explore the cause of death that is relatively higher in South Korea and came up with measures for resolution. METHODS: The statistics were based from section ICD(International Classification of Diseases)-10 of WHO(World Health Organization) Mortality Database. Among the OECD(Organization for Economic Cooperation and Development) countries, 15 countries with higher GDP(Gross Domestic Product) than South Korea were studied by the mortality rate from 2005 to 2010 sorted into two groups: 0 year group and 1-4 years group. Then the cause of death investigated in detail. RESULTS: Among the 15 countries, average mortality of 0 year group in Korea ranked 8th and the average mortality of 1-4 years group ranked 4th out of 15. There were no significance in the mortality of 0 year group caused by any specific disease, but unnatural death was ranked 2nd after the United States. The natural death of 1-4 years group was ranked 6th, and the unnatural death was ranked 2nd after the Unites States. Among the natural deaths of 1-4 years group, the cause of death significantly higher was found to be disease G(nervous system disease). Among the subgroups of disease G, the orders went epilepsy, cerebral palsy, paralysis, and inflammatory disease. CONCLUSIONS: We have identified major causes of death of children under age 5. The highest proportion of cause of death in 1-4 years group was nervous system disease and we have proposed resolution. Henceforth, this data will be used as a foundational data for formulating policies relation to the Mother-Child Health.
