  • Malignant mesothelioma (MM) is the aggressive tumor of serosal surfaces. There are crude pathogenetic results regarding the biology of MM. Coordinated upregulations of p53 gene expression are shown in malignancies. We believed that there are changes in the p53 expression with transformation from reactive hyperplasia to MM. A 65-year-old male was admitted the hospital because of left pleuritic chest pains in 2004. Chest computed tomography (CT) results showed left pleural effusions with loculation and pleural thickening. Pathologic findings revealed reactive mesothelial hyperplasia. In 2008, the patient again felt left pleuritic chest pains. Chest CT showed progressive thickening of the left pleura. Pathologic diagnosis was atypical mesothelial hyperplasia. In 2011, chest CT showed progressive thickening of his left pleura. He was diagnosed with well-differentiated papillary mesothelioma. Serial change was analyzed by immunohistochemical staining for p53 of pleural tissues. There were no remarkable changes in p53 expressions during the transformation to MM.

  • Purpose: To estimate the incidence of breast cancer in Yemeni female patients presenting with a breast mass. Materials and Methods: This retrospective study was carried out with 595 female patients with palpable breast lumps, attending to Alkuwait university hospital, Sana'a, Yemen. Triple assessment, including breast examination, mammography and biopsy (FNAC, core needle, or excision), for all patients were performed. Results: The incidences of benign and malignant lesions was calculated. Some 160 (26.9%) of 595 patients had malignancies; 213 (35.8%) were fibroadenomas; 12 (2.0%) were fibrocystic change; 143 (24.03%) were inflammatory lesions (including mastitis and ductectasia); 62 (10.4%) were simple cysts, while 5 (0.8%) were phyllodes tumors. The mean age of patients with malignant lumps was 44.3 years. Conclusions: Among Yemeni female patients with palpable breast lumps, the rate of breast cancer is high, with occurrence at an earlier age than in Western countries. Improving breast cancer awareness programs and increasing breast cancer screening centers inb different areas of Yemen are needed to establish early diagnosis and offer early and optimal treatment.

  • Iinflammatory myofibroblastic tumor(IMT) is a benign chronic inflammatory mass composed of proliferative myofibroblasts. It is a space occupying lesion which could potentially covert to malignant tumor. Treatment guideline of the disease has not been established due to its rarity. We demonstrate a 60-year old male who had surgical excision for IMT of the cervical esophagus. During the follow-up period, he revealed recurrent tumor which showed sarcomatous change with distant metastasis. We reported this rare case with review of the literature.

  • Background: This study aims to compare the burden of disease in Korea with other Organization for Economic Cooperation and Development (OECD) countries using the OECD health statistics from 1985 to 2020. Methods: We analyzed potential years of life lost (YLL) per 100,000 population using the Positive value for relative comparison (PARC) index, trend test, and average annual percentage change (AAPC) with logistic regression analysis. Results: The relative disease burden was good for many diseases, but the disease burden was severe for a few diseases in Korea. Diseases with a high relative burden of disease in Korea are as follows; intentional self-harm (YLL2020 575.6, AAPCYLL 2.6%; PARC2020 -1.000, AAPCPARC -15.8%), malignant neoplasms of the liver (YLL2020 136.6, AAPCYLL -3.9%; PARC2020 -1.000, AAPCPARC 0.0%), malignant neoplasms of the stomach (YLL2020 9.0, AAPCYLL 3.2%; PARC2020 -0.556, AAPCPARC -22.9%), Parkinson's disease (YLL2020 575.6, AAPCYLL 2.6%; PARC2020 -1.000, AAPCPARC -15.8%). Conclusion: Diseases with a high burden of disease are needed to be prioritized in the planning and execution of healthcare policies that can contribute to the efficient use of healthcare resources.

  • Background: Activation and inactivation of nuclear factor of kappa light chain gene enhancer in B cells (NFKB) is tightly regulated to ensure effective onset and cessation of defensive inflammatory signaling. However, mutations within NFKB, or change in activation and inactivation molecules have been reported in a few cancers. Although oral squamous cell carcinoma is one of the most prevalent forms of cancer in India, with a development associated with malignant transformation of precancerous lesions, the genetic status of NFKB and relative rates of change in oral precancerous lesions remain unknown. Hence in the present study we investigated all twenty four exons of NFKB gene in two precancerous lesions, namely oral submucous fibrosis (OSMF) and oral leukoplakia (OL) to understand its occurrence, incidence and assess its possible contribution to malignant transformation. Materials and Methods: Chromosomal DNA isolated from twenty five each of OSMF and OL tissue biopsy samples were subjected to PCR amplification with intronic primers flanking twenty four exons of the NFKB gene. The PCR amplicons were subsequently subjected to direct sequencing to elucidate the mutation status. Results: Sequence analysis identified a novel heterozygous mutation, c.419T>A causing substitution of leucine with glutamine at codon 140 (L140Q) in an OL sample. Conclusions: The identification of a substitution mutation L140Q within the DNA binding domain of NFKB in OL suggests that NFKB mutation may be relatively an early event during transformation. To the best of our knowledge, this study is the first to have identified a missense mutation in NFKB in OL.

  • FDG-PET의 반정량적인 당대사지표인 pSUV, aSUV, $TBR_{51}$$TBR_{area}$는 비관혈적으로 악성과 양성 연부조직 병변을 감별하는 데 모두 높은 정확도를 나타내었다. FDG-PET은 연부조직 종양의 평가에서 MRI와 상호보완적인 역할을 할 수 있을 것이다. 또한 FDG-PET은 악성 연부조직 종양환자들의 전이의 발견과 치료 후 추적관찰에도 도움이 될 것으로 생각되며 이에 관한 연구가 계속되어야 할 것이다.

  • 연구배경 : 고립성 폐 결절의 양성과 악성의 감별은 치료와 예후를 결정하는데 중요하지만 결핵성 육아종의 빈도가 높은 국내에서는 감별진단이 쉽지가 않다. 이에 저자들은 최근 고립성 폐 결절의 진단에 정확성이 높다고 알려진 PET의 유용성과 혈당농도와 결절의 표준섭취계수의 차이를 알아보고자 하였다. 방 법 : 2001년 1월부터 2002년 6월까지 전남대학교 의과대학병원에서 시행한 단순 흉부사진상 발견된 고립성 폐 결절과 타 병원에서 이를 주소로 내원한 환자들 중 FDG-PET 및 조직학적인 검사로 진단된 61명의 환자를 대상으로 하였다. 결 과 : 조직학적으로 진단된 61례에서 악성 결절은 48례(편평상피세포폐암 23례, 선암 16례, 소세포폐암 9례), 양성 결절은 13례(염증성 육아종 9례, 결핵종 3례, cryptococcosis 증 l례) 이었다. 침상형을 가진 경우는 모두 악성 결절을 보였으나 분엽성과 침상형을 모두 갖지 않은 경우에서도 악성 결절을 보여 이러한 결절의 변연으로 악성과 양성 결절을 명확히 구분할 수 없었다. PET의 경우 SUV cut-off value를 3.0으로 하였을 때 13례의 양성 결절 중 10례에서 3.0 이하의 수치를 보였으며 3례에서 SUV가 3.0 이상으로 증가되었다. 악성 결절 48례는 모두 SUV가 3.0 이상의 값을 보였다. 악성 결절의 평균 SUV는 $9.52{\pm}5.20$, 양성 결절은 $1.61{\pm}3.60$으로 두 군간에 의의 있게 차이를 보였다. 폐암 환자에서 당뇨병을 가진 환자 군과 당뇨병이 없는 군의 평균 SUV에선 $9.10{\pm}4.51$, $9.65{\pm}5.46$으로 두 군 사이에 차이를 보이지 않았다. FDG-PET 검사의 민감도, 특이도, 양성 예측치 및 음성 예측치는 100%, 77%, 94% 및 100%의 결과를 보여 다른 검사에 비하여 진단적 정확성은 높았으나 상대적으로 특이도는 낮았다. 결 론 : 고립성 폐 결절에 대해 FDG-PET 진단검사는 비침습적인 검사로 다른 검사에 비하여 높은 정확도를 보여 주고 있으며 혈중 포도당 농도에 영향을 받지 않는 것으로 생각되고 있다. 특이도가 낮은점은 결핵종 등이 많은 우리나라에서 더 많은 연구가 이루어져야 할 것으로 생각된다.

  • The cells that make up the body continuously undergo cell division to maintain life, but stress and carcinogens, and physiological stimuli suppress immunological functions in the body and change cells to cancerous cells. The only way to overcome cancer is by treatment through early detection and proper diagnosis. However, because early stage of cancer shows subjective symptoms that are similar to those of other common illnesses, even doctors have difficulty separating cancer from common illnesses in its early stage. However, the Ki(bioenergy) present in our body recognizes and changes to the most minute changes in the body. This method of detecting the change in bioenergy to discover a disease in the early stage to raise treatment success is called the OBET: O-Ring, Bioenergy Test. This method, which is based on the theories of oriental medicine, focuses on tumors, especially malignant tumors, and has shown value in diagnosis and treatment, as witnessed in the clinical applications. The diagnosis method and cases of OBET: O-Ring, Bioenergy Test are presented.

  • A 69-year-old man was referred with left exophthalmos. Computed tomographic (CT) findings detected a well-circumscribed mass in the left side of the intraorbital cavity. At that time, he refused the further evaluation and treatment. About three years later, the size of the mass had enlarged, and the patient's symptoms were getting worse. The mass was completely removed with frontotemporal craniotomy and superolateral orbitotomy. In operative findings, the mass had originated in the lacrimal gland and was well-encapsulated without invasion to the surrounding tissue. In the pathologic findings, the tumor consisted of pleomorphic adenoma with osteosarcomatous change of stromal components. Postoperatively, the adjuvant radiotherapy was done four weeks later. The patient's symptoms were improved. The pleomorphic adenoma with osteosarcomatous change is extremely rare and appropriate treatment is not clearly established. We would like to report this rare case with a review of the literature.

  • Purpose: This study was to examine the clinical characteristics and mortality risk factors of geriatric hospital patients who visited one region-wide emergency department (ED). It's basically meant to develop criteria for the patient management of geriatric hospitals and to provide related information. Methods: A retrospective research study was implemented using electronic medical records. The subjects in this study included 484 geriatric hospital patients who were selected from among 15,994 patients that visited one region-wide ED between January 1, 2014, and December 31, 2015. Results: There were significant differences in death, a change for the better and no change for the better, which were results of treatment, according to the length of stay in hospital, hospitalization in a general ward, not having an operation or surgery, the presence or absence of malignant neoplasm, the insertion of foley catheter, intubation, ventilator and the insertion of central venous catheter. Conclusion: The results of this study suggest that a patient management system is necessary in geriatric hospitals and that competent healthcare workers who can properly respond to emergencies are required as well.
