OBJECTIVES: To estimate the weighting for the disability caused by major cancers in Korea using the Delphi method. METHODS: We selected 19 panelists to estimate the disability weighting of major cancers in Korea by using the Delphi method. To select the relevant kinds of cancers, we used National Death Certificate Data produced by the National Statistical Office in 1996. Then the stability of each delphi round was calculated by using the coefficient of variance. RESULTS: The disability weight of major cancers for males was pancreas cancer(0.36), liver cancer(0.35), esophageal cancer(0.30), stomach cancer(0.27), lung cancer(0.26), and colorectal cancer(0.30). The disability weight of major cancers for females was pancreas cancer(0.36), liver cancer(0.34), esophageal cancer(0.29), stomach cancer(0.28), lung cancer(0.26), and colorectal cancer(0.28). CONCLUSION: The results of this study will provide baseline data useful for the measurement of the burden of disease caused by cancers in Korea.

Bisphosphonates (BPs) are a class of agent used to treat patient with osteoporosis or malignant bone metastases. BPs can be categorized into 2 groups: nitrogen-containing and non-nitrogen containing. Nitrogen-containing BPs are considered to have more toxicity. Despite their clinical benefits, bisphosphonate-related osteonecrosis of jaw(BRONJ) is a significant complication to patients receveing these drugs. Since the first description of BRONJ in 2003 by Marx, the number of reports on BRONJ has been rapidly increasing. BRONJ is considered as an emerging problem in oral & maxillofacial surgery. Generally, osteonecrosis in the maxilla is rare, however BRONJ is found both in the maxilla and the mandible. This is an important feature of BRONJ compared to common infectious osteomyelitis of the jaw. Growing number of case reports, suggest that bisphosphonate therapy may cause exposed, necrotic bone. BRONJ has simillar features compared to IORN (infected osteoradionecrosis). BRONJ has meaningful features established through the interestigation on histopathologic and radiographic findings. These features have an impact on treatment plan and prognosis. This presentation contemplates on features of histopathologic and radiographic findings in bisphosphonate-related osteonecrosis of the jaw.

Rhizomelic chondrodysplasia punctata(RCDP) is a rare autosomal recessive disorder clinically characterized by symmetrical shortening of the proximal limbs, contractures of joints, a typical dysmorphic face, cataracts, and itchyosis. Patients with RCDP can be subdivided into three subgroups based on biochemical analysis and complementation studies. RCDP type I results from mutations in the PEX7 gene encoding the peroxisomal targeting signal type II(PST2) receptors and presents with both a defect in plasmalogen biosynthesis and phytanic acid oxidation. RCDP type II is deficient in the activity of dihydroxyacetonephosphate acyltransferase(DHAP-AT). RCDP type III is deficient in alkyl-dihydroxyacetonephosphate synthase(alkyl-DHAP). We report a case of RCDP type I which was confirmed with biochemical study, fibroblast culture, and gene study.

We describe a case of 43-year-old man who had a pseudoaneurysm of the medial superior genicular artery after arthroscopic partial meniscectomy with standard anterolateral and anteromedial portals. Pseudoaneurysm of the medial superior genicular artery has been reported at the previous superomedial portal site after arthroscopy. Described herein is a unique case that involved the medial superior genicular artery at the previous anteromedial portal site after arthroscopy. The pseudoaneurysm was successfully treated with transcatheter embolization.

The occurrences of thyrotoxicosis in patients with myasthenia gravis have been reported before the knowledge of the pathogenesis of the two disease. Thytotoxicosis is known to occur in 3 to 6 percent of patients with myasthenia gravis and myasthenia gravis occurs in only a fraction of 1 percent of the thyrotoxic populatian. Myasthenia gravis is currently considered as a systemic autoimmune disorder of acetylcholine receptor and often presented with other autoimmune diseases such as SLE, Rheumatoid arthritis. We experienced a 18-year-old woman who presented with graves disease and isolated ocular myasthenia gravis. Chest CT didnot reveal enlarged thymus. The usual treatement of myasthenia gravis associated with thymtoxicosis consists of medical control of the thyrotoxicosis, then thymectomy and later subtotal thyroidectomy. Her ptosis and thyrotoxicosis have improved after the medicatian of anticholinesterase and propylthiourecil. A case of ocular myasthenia gravis with Gravesdisease was experienced, so we reported the case with a brief review of literature.

We present a case report of brain death caused by Salmonella enterica serovar Enteritidis bacteremia. A 53-year-old diabetic male was admitted to our hospital with stupor mentality and fever. No evidence of meningitis was found upon cerebrospinal fluid analysis, but diffuse brain edema was shown by magnetic resonance imaging. S. Enteritidis phage type 7 was isolated from blood cultures. We diagnosed the patient with encephalopathy associated with S. Enteritidis bacteremia and treated him by intravenous administration of ceftriaxone and dexamethasone. Fifteen days after admission, the patient was diagnosed with brain death and became a cadaveric donor. Although encephalopathy associated with S. Enteritidis bacteremia is rare, it should be considered as a serious and potentially lethal complication.

Severe acute respiratory syndrome CoV-2 (SARS-CoV-2) is responsible for the current coronavirus disease 2019 (COVID-19) pandemic. Signaling pathways that are essential for virus production have potential as therapeutic targets against COVID-19. In this study, we investigated cellular responses in two cell lines, Vero and Calu-3, upon SARS-CoV-2 infection and evaluated the effects of pathway-specific inhibitors on virus production. SARS-CoV-2 infection induced dephosphorylation of STAT1 and STAT3, high virus production, and apoptosis in Vero cells. However, in Calu-3 cells, SARS-CoV-2 infection induced long-lasting phosphorylation of STAT1 and STAT3, low virus production, and no prominent apoptosis. Inhibitors that target STAT3 phosphorylation and dimerization reduced SARS-CoV-2 production in Calu-3 cells, but not in Vero cells. These results suggest a necessity to evaluate cellular consequences upon SARS-CoV-2 infection using various model cell lines to find out more appropriate cells recapitulating relevant responses to SARS-CoV-2 infection in vitro.
