지역 사회 획득성 폐렴에 동반된 횡문근 융해증 1예
No full textA-67-year old man was hospitalized due to fever, cough and dyspnea upon exertion, and was treated with intravenous antibiotics. During the hospital course he presented with weakness in his low extremities. The laboratory tests showed an elevated CK level and myoglobinuria. He was diagnosed with rhabdomyolysis with community-acquired pneumonia and treated accordingly. Subsequently, his symptoms and signs of rhabdomyolysis improved.Y

Bronchiolitis obliterans organizing pneumonia in Korea
No full textAn analysis of the clinical features in 23 cases of bronchiolitis obliterans organizing pneumonia (BOOP) in Korea is presented. Six were men and 17 were female, with a mate-to-female ratio of 1:2.4. Idiopathic BOOP was present in 18 of these patients, connective tissue disease-associated BOOP in five and all of them were females. The most frequent symptoms were dyspnoea and coughing in both groups; and crackles were the most prominent physical findings. Leukocytosis was observed in seven of the idiopathic BOOP group and all in the connective tissue disease-associated BOOP group. In most cases, FVC, FEV1 diffusing capacity and arterial O2 pressure were reduced. In roentgenographic study, patchy air space consolidation was the major finding and subpleural predominance was observed in the majority of patients in both groups. Migration of lesions were identified in only two patients with idiopathic BOOP. Steroid treatment was effective in all of idiopathic BOOP. In contrast to previous reports, an analysis of the 23 Korean BOOP patients showed several interesting points. First, a female predominance was observed. Second, migration of lesion was rare. Third, it did not show any different prognosis in patients with reticular pattern on roentgenogram compared with patients with patchy air space consolidation on roentgenogram. Whether these differences were due to ethnic or environmental factors is to be determined.N
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Clinical characteristics and prognosis of lymphocyte dominant exudative pleural effusion with low ADA, low CEA, negative cytology and negative AFB smear
No full textBackground: A pleural effusion is a common medical problem. Despite several diagnostic tests, 15-20% of pleural effusions go undiagnosed. The aim of this study was to evaluate the clinical characteristics and prognosis of a lymphocyte dominant exudative pleural effusion with a low adenosine deaminase (ADA), low carcinoembryonic antigen (CEA), negative cytology and negative acid fast bacilli (AFB) smear. Method: From Jan 2000 to Aug 2001, 43 patients with lymphocyte dominant exudative pleural effusions whose AFB smear and cytologic exam were negative, their pleural fluid ADA level was < 40 IU/L, and their CEA level was < 10 ng/mL were enrolled in this study. A retrospective analysis of the patients' medical records was carried out. Result: Among 31 of the 43 cases (72%), probable underlying diseases causing the pleural effusion were identified: 21cases of malignant diseases, 4 cases of liver cirrhosis, 2 cases of pulmonary tuberculosis, 1 case of end stage renal disease, 1 case of a chylothorax, 1 case of a post CABG (coronary artery bypass graft) state, 1 case of a pulmonary embolism. No clinically suspected etiology was identified in the remaining 12 cases (28%). Of these 12 pleural effusions, 7 cases spontaneously resolved, 2 effusions resolved with antibiotics, and the other 2 cases were persistent. Conclusion: Lymphocyte dominant exudative pleural effusions with a low ADA, low CEA, negative cytological exam, and negative AFB smear, but without a definite cause might have a benign course and clinicians can observe them with attention.N
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
