Cardiac tamponade occurring after open heart surgery is a rare, but fatal complication necessitating urgent drainage, though postoperative pericardial effusion is common. Two-dimensional echocardiographic study provides excellent postoperative visualization of pericardial effusion. Catheter insertion guided by two-dimensional echocardiography has been used to accomplish nonoperative drainage of symptomatic postoperative pericardial effusion in 4 cases. This technique offers simplicity, safety, and cost effectiveness.

Primary pericardial malignant mesothelioma is a lethal and rare cardiac neoplasm of mesodermal origin. Most cases are associated with history of pericarditis with constriction and/or tamponade. Authors experienced a case of primary pericardial malignant mesothelioma in a 55-year old female who had suffered from dyspnea and chest pain. Pericardial nodules revealed intense uptake by FDG-PET scan and confirmed as primary pericardial malignant mesothelioma by thoracoscopic biopsy. Here we report this case with a brief review of the relevant literatures.

Asbestos is widely used in the textile, asbestos cement, construction products, friction material, paper products, insulation products, chemical and plastic products because of its heat resistance, flexibility, tensile strength, and texturability. It is now generally recognized that longterm and excessive inhalation of asbestos dust causes asbestosis, lung cancer, malignant mesothelioma and malignancies in other organs such as cancer of gastrointestinal tract, leukemia, lymphoma. Although eighty thousand tons of asbestos has been annually consumed since 1979 in korea, it has not been reported asbestos and lung cancer by asbestos dust so far, while a case of mesothelioma was officially diagnosis as a occupational disease at 1993. We experienced firstly a case of asbestosis and lung cancer caused simultanously by occupational asbestos exposure 11 years, which was confirmed by chest x-ray, pulmonary function test, chest CT and HRCT, bronchoalveolar lavage, and gallium scan. And so We present a case of asbestosis, pleural effusion and lung cancer with a review literature.

Mycoplasma pneumioniae has a unique genomic composition, cellular biology, and a fastidious nature as the smallest cell-free living organism that lacks a cell wall. Previous studies have suggested that a clinical manifestation of a M. pneumoniae infection is a consequence of a host immune response, particularly involving cellular immunity. Adenosine deaminase (ADA) is the main T-lymphocyte enzyme, and its activity is high in diseases where cellular immunity is stimulated. Therefore, its activity is useful for diagnosing a tuberculous pleural effusion. A pleural effusion is found in 5-20% of Mycoplasma pneumonia patients. However, there are few reports of high ADA activity in a mycoplasmal pleural effusion. Here we report a case of Mycoplasma pneumoniae infection established by a polymerase chain reaction and serologic tests, accompanying high ADA activity in a pleural effusion.

Background: It is said that tuberculous pleuritis responds well to anti-tuberculous drug in general, so no further aggressive therapeutic management is unnecesarry except in case of diagnostic thoracentesis. But in clinical practice, we often see some patients who need later decortication due to dyspnea caused by pleural loculation or thickening despite several months of anti-tuberculous drug therapy. Therefore, we want to know the clinical difference between a group who received decortication due to complication of tuberculous pleuritis despite of anti-tuberculous drug and a group who improved after 9 months of anti-tuberculous drug only. Methods: We reviewed 20 tuberculous pleuritis patients(group 1) who underwent decortication due to dyspnea caused by pleural loculation or severe pleural thickening despite of anti-tuberculous drug therapy for 9 or more months, and 20 other tuberculous pleuritis patients(group 2) who improved by anti-tuberculous drug only and had similar degrees of initial pleural effusion and similar age, sex distribution. Then we compared between the two groups the duration of symptoms before anti-tuberculous drug treatment and pleural fluid biochemistry like glucose, LDH, protein and pleural fluid cell count and WBC differential count, and we also wanted to know whether there was any difference in preoperative PFT value and postoperative PFT value in the patients who underwent decortication, and obtained following results. Results: 1) Group 1 patients had lower glucose level{$63.3{\pm}30.8$(mg/dl)} than that of the group 2{$98.5{\pm}34.2$(mg/dl), p<0.05}, and higher LDH level{$776.3{\pm}266.0$(IU/L)} than the group 2 patients{$376.3{\pm}123.1$(IU/L), p<0.05}, and also longer duration of symptom before treatment{$2.0{\pm}1.7$(month)} than the group 2{$1.1{\pm}1.2$(month), p<0.05}, respectively. 2) In group 1, FVC changed from preoperative $2.55{\pm}0.80$(L) to postoperative $2.99{\pm}0.78$(L)(p<0.05), and FEV1 changed from preoperative $2.19{\pm}0.70$(L/sec) to postoperative $2.50{\pm}0.69$(L/sec)(p<0.05). 3) There was no difference in pleural fluid protein level($5.05{\pm}1.01$(gm/dL) and $5.15{\pm}0.77$(gm/dl), p>0.05) and WBC differential count between group 1 and group 2. Conclusion: It is probable that in tuberculous pleuritis there is a risk of complication in the case of showing relatively low pleural fluid glucose or high LDH level, or in the case of having long duraton of symptom before treatment. We thought prospective study should be performed to confirm this.

The diagnostic accuracy of routine cytological preparations from effusions ranges from 60% to 70%. Immunohistochemical markers, especially tumor-associated antigens, have been successfully employed to increase diagnostic sensitivity in effusion cytology. However, more than two different antibodies in diagnosis of effusions are needed. In the view of prevalence of abnormalities of p53 gene in human malignancies we investigated the diagnostic usefulness of demonstration of p53 protein immunoreactivity in distinguishing benign changes versus malignant processes in effusions. p53 protein expression was studied immunohistochemically in 76 effusions(28 malignant and 48 benign) using anti-human p53 antibody p53 immunoreactivity was identified in 19 of 28(67.9%) malignant effusions. In contrast, no p53 immunoreactivity was observed in all benign effusions. A specificity of 100% and a sensitivity of 67.9% were observed. These results suggest that immunohistochemical detection of p53 protein seems to be helpful in distinguishing benign changes versus malignant processes in effusions, although its principal limitation is its relatively low sensitivity.

The specificity of cytologic examination in effusions is high but the sensitivity is low. Therefore, various ancillary methods for the detection of malignant cells in effusions have been proposed. The presence of an aneuploid cell population is generally considered diagnostic of malignancy. The purpose of this study is to determine whether the routine use of flow cytometry adds to standard cytologic evaluation in effusions. We did flow cytometric DNA analysis in 76 effusions(28 malignant and 48 benign fluids). All the 48 benign effusions were diploid. There were 12(42.9%) aneuploid and 16(67.1%) diploid malignant effusions. Based on these results flow cytometric DNA analysis had a sensitivity of 42.9% and a specificity of 100%. These results suggest that flow cytometric DNA analysis may be a useful adjunct to conventional cytology, but its principal limitation is us relatively low sensitivity.

Propolis는 꿀벌이 다양한 식물로부터 모아온 수지상의 물질이며 꿀벌의 분비물과 수목의 삼출액 등의 다양한 형태를 함유하고 있다. Propolis는 고대로부터 항생작용과 상처치유에 효과적인 혼합물로 알려져 있다. 또한 에탄올 추출 Propolis는 항박테리아, 항미생물, 항곰팡이, 마취성, 항염증, 통증저하, 면역상승과 세포증식억제작용 특성과 같은 약물학적 활성을 나타낸다고 알려져 있다. 이 연구에서는 국내산 Crude Propolis로부터 얻어진 EEP의 첨가가 미생물의 성장에 미치는 영향을 조사하였다. Paper Disc Diffusion Method와 균주의 성장에 따른 저해 정도를 확인하기 위한 20mg EEP/100mL MH배지에서도 균주의 성장을 저해함을 확인할 수 있었다. 70% EEP와 95% EEP에서 모두 저해를 확인할 수 있었고95% EEP에서 저해활성이 더 좋았다.

Rifampin is a bactericidal antibiotic used primarily in the treatment of tuberculosis. The adverse effects of rifampin, though few, include dermatologic, gastrointestinal, and hepatic manifestations. Occasionally it produces a flu-like syndrome, interstitial nephritis, hemolytic anemia, and thrombocytopenia. These manifestations usually appear in patients who take the drug intermittently. We experienced a 13 year-old girl who developed thrombocytopenia during rifampin administration of daily dosage, therefore we report a brief review with the related literatures.
