Cystic fibrosis is a hereditary disease involving recessive transmission. The fundamental abnormality consists of the production of abnormal secretion from a variety of exocrine glands such as salivary and sweat glands and those of the pancreas, colon, and tracheobronchial trees. Cystic fibrosis is the most common lethal genetically transmitted disease among whites, but is uncommon in Asians, including Koreans. Although a case involving a Korean was reported in 1988, the focus was diagnosis rather than the radiological findings. In the case of cystic fibrosis we now describe, the focus is inverted: we enphasise the reported in 1988, focusing on radiologic findings

Purpose: After the RS (respiratory syncytial) virus, the influenza virus is the most common cause of childhood lower respiratory tract infection. We assessed the radiologic findings of childhood lower respiratory tract infection by the influenza virus. Materials and Methods: A total of 105 pediatric patients (76 males and 29 females; mean age, 2.4 years) with symptoms of respiratory tract infection were examined between March 1997 and April 2000. Nasopharyngeal aspirates were obtained and influenza virus infection was confirmed by direct or indirect immunofluorescent assays. Peribronchial infiltration, hyperinflation, atelectasis, pulmonary consolidation, and hilar lymphadenopathy were evaluated retrospectively at simple chest radiography. Results: Bilateral perihilar peribronchial infiltration was noted in 78.1% of patients (n=82), hyperinflation in 63.8% (n=67), atelectasis in 3.8% (n=4; segmental 50%, lobar 50%), and pulmonary consolidation in 16.2% [n=17; segmental 70.6% (n=12), lobar 29.4% (n=5)]. Hilar lymphadenopathy was noted in one patient in whom there was no pleural effusion, and subglottic airway narrowing in 12 of 14 in whom the croup symptom complex was present. Conclusion: The major radiologic findings of influenza virus infection were bilateral perihilar peribronchial infiltration and hyperinflation. In some patients, upper respiratory tract infection was combined with subgolttic airway narrowing. Atelectasis or pleural effusion was rare.

최요원,전석철,박충기,주경빈,함창곡,이승로,Choe, Yo-Won,Jeon, Seok-Cheol,Park, Chung-Gi,Ju, Gyeong-Bin,Ham, Chang-Gok,Lee, Seung-Ro The Korean Radiological Society 2004 대한영상의학회지 Vol.50 No.1

Pulmonary involvement is more common in systemic lupus erythematosus (SLE) than in any other connective tissue disease, and more than half of patients with SLE suffer from respiratory dysfunction during the course of their illness. Although sepsis and renal disease are the most common causes of death in SLE, lung disease is the predominant manifestation and is an indicator of overall prognosis. Respiratory disease may be due to direct involvement of the lung or as a secondary consequence of the effect of the disease on other organ systems.

최요원,전석철,박충기,Choe, Yo-Won,Jeon, Seok-Cheol,Park, Chung-Gi 대한영상의학회 2003 대한영상의학회지 Vol.48 No.3

목적: 구개열 환아에서 흡인성 폐렴의 발생율과 완전형과 불완전형 구개열 환아간의 흡인성 폐렴 발생율의 차이가 있는지 알아보고자 하였다. 대상과 방법: 최근 3년간 첫 교정을 위해 내원한 100명의 구개열 환아를 후향적으로 조사하여 자주 폐렴에 걸린 병력이 있고, 폐렴이 생기기 전에는 기도 흡인의 과거력이 있으며 단순흉부 촬영에서 폐렴의 소견이 있는 환아의 빈도와 폐렴의 위치, 그리고 완전형과 불완전형 구개열 환아 군간에 흡인성 폐렴의 빈도 차이가 있는지를 분석하였다. 결과: 100명의 구개열 환아 중 35명에서 흡인성 폐렴을 보였고 (35%),완전형과(27 of 70명, 39%)불완전형 구개열 환아군 (8 of 30명,27%)간에 빈도의 통계적 차이는 없었다 (p=0.36). 폐렴은 좌하엽 (15예), 우상엽 (8예), 우하엽 (6예)의 순서로 분포하였다. 결론: 흡인성 폐렴은 구개열 환아에서 빈번하게 발생하며 완전형과 불완전형 구개열 환아 군간의 흡인성 폐렴 발생의 발생률은 의미있는 차이를 보이지 않았다.

Purpose: To evaluate the radiographic and CT findings of pulmonary complications other than pulmonary edema arising from renal transplantation. Materials and Methods: Among 393 patients who had undergone renal transplantation at our hospital during a previous ten-year period, 23 with pulmonary complications other than pulmonary edema were included in this study. The complications involved were infection caused by CMV (n=6), bacteria (n=4), fungus (n=4), tuberculosis (n=2), varicella (n=1) or chlamydia (n=1), and malignancy involving lung cancer (n=4) or Kaposi's sarcoma (n=1). Two chest radiologists reviewed all images. Results: The complications manifesting mainly as pulmonary nodules were lung cancer(4/4), tuberculosis (1/2), and Kaposi's sarcoma(1/1). Pulmonary consolidation was a main feature in bacterial infection(4/4), fungal infection(3/4), tuberculosis(1/2), chlamydial infection(1/1), and varicellar pneumonia(1/1). Ground-glass attenuation was a main CT feature in CMV pneumonia(4/6), and increased interstitial marking was a predominant radiographic feature in CMV pneumonia(2/6). Conclusion: The main radiologic features described above can be helpful for differential diagnosis of the pulmonary complications of renal transplantation.

Purpose: To compare the diagnostic role of arthrosonography, conventional ultrasonography and MR arthrography in the assessment of glenoid labral tear, glenoid rim fracture and humeral head fracture of the shoulder joint. Materials and Methods: The findings of arthrosonography, conventional ultrasonography and MR arthrography were prospectively evaluated in 62 consecutive patients with chronic pain or a history of recurrent dislocation of the shoulder joint. The glenoid labrum was arbitrarily divided into four quadrants: anterosuperior, anteroinferior, posterosuperior, and posteroinferior, and for each, visibility at arthrosonography and conventional ultrasonography was subjectively scored as one of four grades. By means of statistical analysis, the two techniques were then compared. Twenty-six patients subsequently underwent arthroscopy, and the presence or absence of labral tear, glenoid rim fracture and humeral head fracture was determined. The sensitivity and specificity of each modality were separately calculated for each of the three types of shoulder joint injury, and observed differences in these findings were statistically analysed. Results: For all individual quadrants of the labrum, visibility at arthrosonography was higher than at conventional ultrasonography (p<.0001). For the detection of labral tear, the sensitivity of arthrosonography was not significantly higher than that of conventional ultrasonography (p>.05), though its specificity was significantly higher (p=.003). In this respect, there was no significant difference in sensitivity or specificity between arthrosonography and MR arthrography (p>.05). For the detection of glenoid rim and humeral head fracture, there were no statistical differences in sensitivity and specificity between the three imaging modalities (p> .05). Conclusion: Compared with conventional ultrasonography, arthrosonography provides higher visibility of the labrum, thus improving the capacity of ultrasonography to detect labral tear. Arthrosonography could therefore be useful in the diagnosis of labral tear, glenoid rim fracture and humeral head fracture, and may thus partially replace MR arthrography.

전 세계적으로 기후변화와 환경변화로 인한 재난, 재해의 발생 빈도가 빈번해지고 규모가 커지면서 지구시스템의 변화를 이해, 감시, 예측하기 위한 지구관측(Earth Observation)관련 국제협력이 강화되고 있다. 이에 지구관측에 필수적인 원격탐사 자료를 이용한 공중모니터링의 중요성이 매우 커지고 있다. 이와 같은 상황에서 이 논문은 국내외 공중모니터링 관련 해외 협력체계 및 연구 현황을 살펴본 후, 국내의 공중모니터링 체계의 발전방향에 대하여 연구 및 기술적 측면, 조직 및 제도적 측면, 전략적 측면에서 논의하였다. 이 연구의 결과는 체계적인 공중모니터링 방안 수립에 대한 토대를 제공하고 향후 국내 전지구관측시스템(Global Earth Observation System of Systems) 구축을 위한 기초적 자료로 사용될 수 있을 것으로 기대된다.

N/A To investigate the prevalence of antibodies to hepatitis C virus infection in patients with various chronic liver diseases in Korea, we tested 240 serum samples using the Abbott enzyme immunoassay method. The result sare summarized as follows: 1) Among 57 patients with post-transfusion hepatitis(PTH), 38(66.7%) were positive for anti-HCV. Four out of 57 patients were also positive for HBsAg, of which three were positive for anti-HCV. 2) In 131 patients with chronic non-A, non-B hepatitis, who had no history of blood transfusions, 60(45.8%) were positive for anti-HCV; of them 42 out of 85(49.4%) patients with chronic hepatitis, 14 out of 34(41.2%) with liver cirrhosis, and four out of 12(33.3%) with fatty liver and alcoholic hepatitis were positive for anti-HCV. 3) In 27 patients with HBsAg negative hepatocellular carcinoma, 13(48.1%) were positive for anti-HCV. 4) In 25 patients with chronic hepatitis B, who were negative for HBeAg but had active liver disease by liver biopsy, two(8%) were positive for anti-HCV. In conclusion, the prevalence of type C hepatitis in Korea was similar to that of other countries. This test is useful in confirming the diagnosis of various chronic viral hepatitis patients in Korea. Meanwhile, studies of larger numbers of patients and blood donors are necessary to estimate the exact prevalence of this type of hepatitis in Korea.
