Hypercoagulability disorders are commonly encountered in clinical situations in patients with a variety of cancers. However, several hypercoagulability disorders presenting as first symptoms or signs in cancer patients have rarely been reported. We herein described a case of a woman with adenocarcinoma of the lung presenting with deep vein thrombosis, nonbacterial thrombotic endocarditis, recurrent cerebral embolic infarction, and heart failure.

Hyperhomocysteinemia is an independent risk factor for cardiovascular, cerebrovascular and peripheral vascular diseases that are complicated by atherosclerosis and a thromboembolism. An increased level of plasma homocysteine develops from a genetic defect in the of enzyme for the homocysteine metabolism or a vitamin deficiency. Hyperhomocysteinemia has direct toxic effect on the vascular endothelium and causes damages to the antithrombotic action of vascular endothelial cells. Most cases of hyperhomocysteinemia are asymptomatic, but cardiopulmonary or cerebrovascular incidents developin rare cases. In the case of a thromboembolism with an unknown cause, hyperhomocysteinemia should be considered in a differential diagnosis. The authors report a case of pulmonary thromboembolism in a patient with hyperhomocysteinemia with a review of the relevant literature.

Methotrexate (MTX) has been established as a standard disease-modifying anti-rheumatic drug. If adequate disease control is achieved for a reasonable period of time, tapering the MTX dosage is recommended because the chronic use of MTX can result in opportunistic infection. We present here a case of a woman with rheumatoid arthritis taking MTX, and the woman developed actively caseating endobronchial Mycobacterium intracellulare disease with pulmonary infiltrations. After discontinuing the MTX, the patient was able to tolerate 18 months of antimycobacterial treatment without flare ups of rheumatoid arthritis, and she completely recovered from nontuberculous mycobacterial respiratory disease.

Ganciclovir resistance of human cytomegalovirus is associated with mutations in the viral UL97 gene and poses severe problems for immunocompromised patients. In this study, PCR-based restriction fragment length polymorphism and sequencing analyses detected the UL97 D605E mutation in all five clinical isolates from patients with ganciclovir-resistant human cytomegalovirus infection during prolonged ganciclovir therapy, whereas the M460V mutation was only present in 1 of 5 isolates. On the other hand, the detection rates of the D605E mutation in the stored available DNA samples from the donor and allogeneic stem cell transplantation recipients were 66.7% and 93.7%, respectively, suggesting that the presence of D605E mutation was not associated with the ganciclovir exposure. Although the D605E mutation may not be related to ganciclovir resistance, we suggest that this mutation could be an important molecular marker of human cytomegalovirus evolution in East Asian countries. Moreover, the restriction fragment length polymorphism method using the restriction enzyme HaeIII, which is generally used to detect the UL97 A591V mutation, could also detect the D605E mutation and may therefore be a useful tool for future research on the investigation of UL97 gene mutations.

Objectives: The purpose of this study was to review the status of numeric rating scale (NRS) usage and suggest the potential for use in multicenter retrospective studies of various diseases. Methods: Articles published from 2011 to 2021 that used the keywords "NRS", "Multi-center", and "RCT" were identified in foreign databases, including EMBASE, PubMed, CENTRAL. The articles were analyzed according to their use of "NRS" by symptoms and by disease group using the major classifications of the Korean Standard Classification of Diseases (KCD-7). Results: Classification by symptom in a total of 288 articles illustrates that the NRS was not only commonly used in pain evaluation but also for non-pain symptoms. In usage with non-pain symptoms, chief complaint of patients was the most common at 79%, and other factors included treatment satisfaction, evaluation of daily life, and sleep quality. In disease classification according to the KCD-7, the NRS was commonly used in connection with musculoskeletal and connective tissue diseases but was also utilized in various other disease groups. Conclusions: This study confirms usage of the NRS in multi-center RCTs, as the NRS was widely used in all types of diseases and symptoms. Considering the result and the advantages of the NRS, it is recommended for use as a daily evaluation tool for the collection of common data in multicenter retrospective studies.

Amyloidosis is defined as the presence of extra-cellular deposits of an insoluble fibrillar protein, amyloid. The pulmonary involvement of amyloidosis is usually classified as tracheobronchial, parenchymal nodular, or diffuse alveolar septal. A single nodular lesion can mimic various conditions, including malignancy, pulmonary tuberculosis, and fungal infection. To date, only one case of nodular pulmonary amyloidosis has been reported in Korea, a case involving multiple nodular lesions. Here, we report and discuss the case of a patient having single nodular amyloidosis.

Pulmonary alveolar proteinosis is a rare disorder in which lipoproteinaceous material accumulates within the alveoli. We report a case of pulmonary alveolar proteinosis in a 41 year old female patient. She complained of a dry cough in the preceding 6 months. She presented symptoms of mild hypoxemia and diffuse infiltration at both lower lung fields. A milky fluid was obtained by bronchoalveolar lavage. We confirmed by light microscopic examinations of the lung tissues obtained by transbronchial lung biopsy. Through several follow-ups, the patients symptoms were mild.
