PURPOSE. To longitudinally assess the quality of life in maxillectomy patients rehabilitated with obturator prosthesis. MATERIALS AND METHODS. Thirty-six subjects were enrolled in the span of 16 months, out of which six were dropouts. Subjects (age group 20-60 years) with maxillary defects, irrespective of the cause, planned for definite obturator prosthesis, were recruited. The Hindi version of European Organization for Research and Treatment of Cancer, Head and Neck version 1 of Quality of Life Questionnaire was used before surgical intervention and one month after definitive obturator. Questionnaire includes 35 questions related to the patient's physical health, well being, psychological status, social relation and environmental conditions. The data were processed with statistical package for social science (SPSS). Probability level of P<.05 was considered statistically significant. RESULTS. The quality of life after rehabilitation with obturator prosthesis was 81.48% (${\pm}13.64$) on average. On item-level, maximum mean scores were obtained for items problem with teeth ($1.87{\pm}0.94$), pain in mouth ($1.80{\pm}0.92$), trouble in eating ($1.70{\pm}0.88$), trouble in talking to other people ($1.60{\pm}1.22$), problems in swallowing solid food ($1.57{\pm}1.22$) and bothering appearance ($1.53{\pm}1.04$); while minimum scores were obtained for the items coughing ($1.17{\pm}0.38$), hoarseness of voice ($1.17{\pm}0.53$), painful throat ($1.13{\pm}0.43$), trouble in having social contacts with friends ($1.10{\pm}0.40$) and trouble having physical contacts with family or friends ($1.10{\pm}0.31$). CONCLUSION. Obturator prosthesis is a highly positive and non-invasive approach to improve the quality of life of patients with maxillectomy defects.

The urgent needs to establish hospice care systems in Korea arise from the following reasons: 0) a drastic increase in chronically ill patients with the increase of aged population: (2) rapid changes in living environment from the traditional habitation (e. g., Many Koreans living in apartment complexes, which is the most popular form of modern residence in recent years, prefer to die in the hospital.): the overall increase in patients with advanced cancer: (4) recent trends in early discharge of terminally ill patients from the limited hospital facilities to accomodate other medical insurance beneficiaries; (5) easy acceptance of euthanasia owing to the recent social atmosphere that belittles the dignity of human life; (6) medical and nursing care of AIDS patient in terminal stage; (7) and the problem associated with inhumane medical care system, overtreatment, and groundless fears against narcotics. Terminally ill patients were used to be treated in the hospital in the past. In these days, however, they are forced to have home cares with little assistance from the qualified medical personnel because of insufficient hospital facilities, which are even short for the need of emergency patients and provide priority cares to medical insurance beneficiaries with other acute problems. And yet, neither are there any administrative organizations nor systematic medical studies that deal with the level of terminally ill patient's need, their family's problems and resources of hospice care systems in Korea. Thus, most patients are not able to get appropriate medical care at the terminal stage of their lives. The objective of this study is to make comprehensive database for various hospice care organization currently in operation, link them through medical information system, and develop an easily accessible hospice care model that meets the need of most Korean people. Our survey results may be summarized as follows: Nationally there are 40 organizations that provide partial or full hospice care. However, these organizations are not linked to any formal medical service network. Furthermore, the objective of hospice care, care principles, personnel with appropriate training, educational programs, standard for care, costs, consulting service to patients' family members, the extent of medical care from professional staff members, status of hospice facility, and management of those institutions are neither clearly defined nor organized compared to the international hospice care standards. The surveys on patients of terminal stage. grouped in hospice and non-hospice care patients. reveal what they want visiting nursing care to help their pain control. psychological. social and spiritual demands. While the more than 90% of hospice care patients want to reduce their pains. the non-hospice care patients. in addition to their desire for pain control. demanded more psychological. social and spiritual helps as well. The results of this research could be utilized to 0) define the standard of hospice care. (2) provide the guidance for hospice medical care costs. (3) establish the database of hospice care systems. (4) develop softwares. (5) build communication network through Medinet. and (6) provide an organized visiting home nursing care system. These information should be a valuable resource to many medical staffs who are involved in cancer therapy. nursing care. and social welfare programs.

Background: Chronic hepatitis B (CHB) infection is one of the important causes of hepatocellular carcinoma (HCC) in Thailand, involved in the pathogenesis and leading to a development of HCC with or without cirrhotic changes of the liver. This study was aimed to investigate the predictive factors for HCC among CHB patients in a tertiary care center in Thailand. Materials and Methods: We conducted a retrospective study of CHB patients with or without HCC during the period of January 2009 and December 2014 at Thammasat University Hospital, Pathumthani, Thailand. Data on clinical characteristics, biochemical tests and radiologic findings were collected from review of medical records. Results: A total of 266 patients were diagnosed with CHB in Thammasat university hospital during the study period. However, clinical information of only 164/266 CHB patients (98 males, 66 females with mean age of 49.4 years) could be completely retrieved in this study. The prevalence of HCC in CHB infection in this study was 38/164 (23.2%). CHB patients with HCC had a mean age older than those without HCC (59.5 vs 47 years, P-value = 0.01). Furthermore, history of upper GI bleeding, tattooing, blood transfusion, and chronic alcoholism were significantly more common in CHB patients with HCC than patients without HCC (13.2% vs 3.2% P-value 0.03, OR = 4.6, 95%CI = 1.2-18.1, 20% vs 3.9%, P-value = 0.01, OR= 6.1, 95% CI= 1.6-23.6, 20% vs 6.3%, P-value = 0.03, OR = 3.8, 95%CI =1.1-12.7, 62.2% vs 30.3%, P-value <0.0001, OR = 3.7, 95%CI= 1.7-8.1 respectively). Interestingly, more CHB patients with HCC had evidence of cirrhosis than those without HCC (78.9% vs 20.4%, P-value <0.0001, OR = 14.6, 95%CI = 5.8-36.7). In CHB patients with HCC, surgical therapy provided longer survival than radiofrequency ablation (RFA) (72 vs 46.5 months, P-value= 0.04). The mean survival time after HCC diagnosis was 17.2 months. Conclusions: HCC remains a major problem among patients with CHB infection in Thailand. Possible risk factors are male gender, history of upper GI bleeding, chronic alcoholism, tattooing, blood transfusion and evidence of cirrhosis. For early stage HCC patients, surgical treatment provided longer survival time than RFA. Most HCC patients presented with advanced disease and had a grave prognosis. Appropriate screening of CHB patients at risk for HCC might be an appropriate approach for early detection and improvement of long-term outcomes.

Cardiac fibrosis is a common feature in chronic hypertension patients with advanced heart failure, and endothelial-to-mesenchymal transition (EndMT) is known to promote Angiotensin II (Ang II)-mediated cardiac fibrosis. Previous studies have suggested a potential role for the transcription factor, ETS-1, in Ang II-mediated cardiac remodeling, however the mechanism are not well defined. In this study, we found that mice with endothelial Ets-1 deletion showed reduced cardiac fibrosis and hypertrophy following Ang II infusion. The reduced cardiac fibrosis was accompanied by decreased expression of fibrotic matrix genes, reduced EndMT with decreased Snail, Slug, Twist, and ZEB1 expression, as well as reduced cardiac hypertrophy and expression of hypertrophy-associated genes was observed. In vitro studies using cultured H5V cells further confirmed that ETS-1 knockdown inhibited $TGF-{\beta}1$-induced EndMT. This study revealed that deletion of endothelial Ets-1 attenuated Ang II-induced cardiac fibrosis via inhibition of EndMT, indicating an important ETS-1 function in mediating EndMT. Inhibition of ETS-1 could be a potential therapeutic strategy for treatment of heart failure secondary to chronic hypertension.

Objective: Computed tomography (CT) is an established method for the diagnosis, staging, and treatment of multiple myeloma. Here, we investigated the potential of photon-counting detector computed tomography (PCD-CT) in terms of image quality, diagnostic confidence, and radiation dose compared with energy-integrating detector CT (EID-CT). Materials and Methods: In this prospective study, patients with known multiple myeloma underwent clinically indicated whole-body PCD-CT. The image quality of PCD-CT was assessed qualitatively by three independent radiologists for overall image quality, edge sharpness, image noise, lesion conspicuity, and diagnostic confidence using a 5-point Likert scale (5 = excellent), and quantitatively for signal homogeneity using the coefficient of variation (CV) of Hounsfield Units (HU) values and modulation transfer function (MTF) via the full width at half maximum (FWHM) in the frequency space. The results were compared with those of the current clinical standard EID-CT protocols as controls. Additionally, the radiation dose (CTDIvol) was determined. Results: We enrolled 35 patients with multiple myeloma (mean age 69.8 ± 9.1 years; 18 [51%] males). Qualitative image analysis revealed superior scores (median [interquartile range]) for PCD-CT regarding overall image quality (4.0 [4.0-5.0] vs. 4.0 [3.0-4.0]), edge sharpness (4.0 [4.0-5.0] vs. 4.0 [3.0-4.0]), image noise (4.0 [4.0-4.0] vs. 3.0 [3.0-4.0]), lesion conspicuity (4.0 [4.0-5.0] vs. 4.0 [3.0-4.0]), and diagnostic confidence (4.0 [4.0-5.0] vs. 4.0 [3.0-4.0]) compared with EID-CT (P ≤ 0.004). In quantitative image analyses, PCD-CT compared with EID-CT revealed a substantially lower FWHM (2.89 vs. 25.68 cy/pixel) and a significantly more homogeneous signal (mean CV ± standard deviation [SD], 0.99 ± 0.65 vs. 1.66 ± 0.5; P < 0.001) at a significantly lower radiation dose (mean CTDIvol ± SD, 3.33 ± 0.82 vs. 7.19 ± 3.57 mGy; P < 0.001). Conclusion: Whole-body PCD-CT provides significantly higher subjective and objective image quality at significantly reduced radiation doses than the current clinical standard EID-CT protocols, along with readily available multi-spectral data, facilitating the potential for further advanced post-processing.

만성 폐쇄성 폐질환은 비가역적, 점진적 기도 폐쇄가 특징인 주요 사망 원인중의 하나이다. 말기 폐쇄성 폐질환 환자는 다양한 신체적, 정서적, 사회적, 기능적 문제로 인해 호스피스 완화의료가 필요하다. 따라서, 완화의료의 목적은 증상 조절, 운동 능력 및 삶의 질 향상이며, 아울러 급성 악화 빈도를 줄이고 질병의 진행을 늦추는 효과를 기대할 수 있다. 다양한 진행 과정 때문에 말기 시점을 예측하기 어렵다. 호흡곤란 정도, 폐기능, 혈액학적 임상 지표를 이용하여 대상자를 선정하는 기준을 마련하고 적용시점을 논의해야 한다. 질환의 특성상 진단 후 초기에는 완치 목적의 치료가 중심이 되어 완화의료가 이를 보완하는 방식으로 적용되다가, 완치 목적의 치료를 위해 입 퇴원을 반복하거나 치료의 반응이 낮고 나쁜 예후가 예상될 때 완화의료 비중이 확대되는 것이 바람직하겠다. 폐쇄성 폐질환 환자에게 적극적으로 호흡재활을 적용하고, 환자의 의사결정을 존중하여 증상 악화 이전에 미리 대책을 마련하고 앞으로의 치료 목표를 논의하기 위한 완화의료 팀을 구성하고, 국내 현실에 맞는 진료 연계 체계를 마련하는 것이 필요하다. 제도가 잘 정착하기 위해서는 일차 의료 및 암환자 대상의 완화의료 전문 팀과의 협업이 중요하며, 우선 고려되어야 할 것이다.

Background: Cancers of the maxillary sinuses are not common and are the most difficult head and neck malignancies in which to make an early diagnosis. Objectives: This reports was conducted to evaluated the efficacy of combination therapy and the relationship between the treatment modalities and their outcome of maxillary sinus cancers. Materials and Methods: We retrospectively analyzed a clinical datas of 46 patients who were treated at the department of Otolaryngology-Head and Neck Surgery. The Catholic University of Korea over 10 years between 1987 and 1996. Results: According to AJCC TNM system, 35 patients presented with $T_4$, 10 with $T_3$, one with T1. Two patients were treated with radiotherapy alone, 4 patients with chemotherapy alone, 17 patients with radiotherapy and chemotherapy, 23 patients with combination of surgery, radiotherapy and chemotherapy. The overall 5 years survival rate for combination therapy group were 57%, but 23 patients treated with the other treatment modalities all died within 2 years except two cases with chemotherapy and radiotherapy or radiotherapy alone. There was a statistical trend for better survival and local control in those patients treated with combination therapy than others(p<0.05). Conclusion: The results of this study suggest that it may be possible to acheive better results with aggressive combination treatment including surgery in advanced cases and to avoid orbital excentration in patients with orbital invasion.
