On 7 December 2007, the Hebei Spirit ran aground near Taean and released approximately 10,900 tons of oil into the sea. Crude oil on the coastal areas and fumes in the air increased the number of health problems among the local population. We report a case of respiratory failure after the oil spill clean-up work. A 66-year-old female was admitted to hospital with cough, sputum, and dyspnea of 1-month duration after the oil spill clean-up. She was diagnosed with community-acquired pneumonia and treated with empirical antibiotics. However, she had progressive respiratory failure without identification of the pathogen. Respiratory failure due to chronic inhalation of hydrocarbons from the crude oil spill clean-up was suspected. After mechanical ventilation care, she recovered from respiratory failure and was discharged. We report a case of severe respiratory toxic effects. after an oil spill clean-up. We concluded that long-term hydrocarbon inhalation during the oil spill clean-up may have induced respiratory failure in this case.

연구배경: 잔여 흉막비후는 결핵성 흉막염 치료 후 흔히 나타날 수 있는 합병증 중의 하나이며, 이로 인해 호흡 기능에 지장을 주는 경우가 있다. 이에 결핵성 흉막염 진단 시 흉수 내의 metalloproteinase (MMP)s와 tissue inhibitor of metalloproteinase (TIMP)s의 농도가 치료 후 잔여 흉막비후가 지속되는 지 예측할 수 있는 인자가 될수 있는 지 알아보고자 하였다. 방법: 2004년 1월부터 2005년 6월 사이에 흉수가 발견되어 입원한 환자를 대상으로 전향적 연구를 시행하였다. 진단 시 흉수의 분석을 통해 결핵성 흉막염, 부폐렴성 흉수, 악성 흉수, 여출액군으로 나누고, 환자의 혈청과 흉수에서 ELISA 방법을 이용하여 MMP-1, -2, -8, -9와 TIMP-1, -2를 측정하였다. 결핵성 흉막염의 경우 흉부엑스선검사로 항결핵제 치료 종결 시점과 마지막 추적 관찰시점에 잔여 흉막비후의 두께를 측정하여 잔여 흉막비후가 있는 군과 없는 군으로 나누었다. 결과: 흉수가 발견되어 입원한 환자 중 제외 기준에 해당하는 환자를 제외하고 총 39명의 환자가 대상이 되었다. 이 중 결핵성 흉막염은 23명, 부폐렴성 흉수 7명, 악성 흉수 7명, 여출액 2명이었다. 결핵성 흉막염 환자 23명중 본원에서 항결핵제 치료를 종료한 환자는 17명이었으며, 이 중 잔여 흉막비후가 없는 군은 10명(59%)이었으며, 잔여 흉막비후가 있는 군은 7명(41%)이었다. 잔여 흉막비후가 있는 군은 흉수 TIMP-1 (41,405.9±9,737.3 ng/mL)이 잔여 흉막비후가 없는 군(29,134.9±8,801.8)보다 의미있게 높았다(p=0.032). 치료 종료 후 평균 8±5개월의 추적관찰이 가능한 13명의 환자들에서, 마지막으로 촬영한 흉부 후전위 촬영에서 잔여 흉막비후가 없는 군은 11명(85%)이었고, 잔여 흉막비후가 있는 군은 2명(15%)이었다. 잔여 흉막비후가 있는 군은 흉수 TIMP-2 (34.4±6.5ng/mL)가 잔여 흉막비후가 없는 군(44.4±15.5)보다 의미있게 낮았다(p=0.038). 결론: 결핵성 흉막염의 잔여 흉막비후의 발생에 TIMP-1과 TIMP-2이 관여 될 수도 있을 것으로 추정된다. Background: Residual pleural thickening (RPT) is the most frequent complication of tuberculous pleurisy (TP), and this can happen despite of administering adequate anti-tuberculous (TB) therapy. Yet there was no definite relation between RPT and other variables. The aim of this study was to examine matrix metalloproteinases (MMPs) and the inhibitors of metalloproteinases (TIMPs) and to identify the factors that can predict the occurrence of RPT. Methods: The patients with newly-detected pleural effusions were prospectively enrolled in this study from January 2004 to June 2005. The levels of MMP-1, -2, -8 and -9, and TIMP-1 and -2 were determined in the serum and pleural fluid by ELISA. The residual pleural thickness was measured at the completion of treatment and at the point of the final follow-up with the chest X-ray films. Results: The study included 39 patients with pleural fluid (PF). Twenty-three had tuberculous effusion, 7 had parapneumonic effusion, 7 had malignant effusion and 2 had transudates. For the 17 patients who completed the anti-TB treatment among the 23 patients with TP, 7 (41%) had RPT and 10 (59%) did not. The level of PF TIMP-1 in the patients with RPT (41,405.9±9,737.3 ng/mL) was significantly higher than that of those patients without RPT (29,134.9±8,801.8) at the completion of treatment (p=0.032). In 13 patients who were followed-up until a mean of 8±5 months after treatment, 2 (15%) had RPT and 11 (85%) did not. The level of PF TIMP-2 in the patients with RPT (34.4±6.5 ng/mL) was lower than that of those patients without RPT (44.4±15.5) at the point of the final follow-up (p=0.038). Conclusion: The residual pleural thickening in TP might be related to the TIMP-1 and TIMP-2 levels in the pleural fluid.

N/A Background: The t (8;21) (q22;q22), which produces the fusion gene AML1/ETO, is associated with relatively good prognosis and, in particular, with a good response to cytosine arabinoside. Analysis of t (8;21) positive leukemic blasts has shown characteristic morphological and immunological features. We performed this study to investigate the incidence of AML1/ETO rearrangement in adult AML, especially in M2 subtype, to make a comparison of morphologic, immunophenotypic and clinical characteristics between AML1/ETO rearrangement positive and negative group in patient with AML and to analyze the correlation with other biological parameters. Methods: From May 1995 to Sep. 2000, fifty-nine patients with AML including twenty-nine AML-M2 were studied. RNAs were extracted from leukemic cells and reverse transcriptase mediated polymerase chain reaction (RT-PCR) for AML1/ETO fusion transcript was done. Chromosome study, immunophenotypic, and clinical characteristics were analysed and statistical analysis was done. Results: The male to female ratio was 32:27 in AML and 17:12 in AML-M2. The median age was 43 years (range 14-86) in AML and 43 years (range 14-77) in AML-M2. The incidence of AML1/ETO fusion transcripts was 22.0% in AML and 44.8% in AML-M2. The morphologic finding of bone marrow in AML-M2 showed higher incidence of Auer rods, large blast with prominent golgi and abnormal granules in AML1/ETO positive patients. There was no significant difference of immunophenotype. AML patients with AML1/ETO rearrangement had a tendency of higher complete remission rate (81.8% vs 56.6%, p=0.13). The overall survival (median 82.2 weeks vs 34.4 weeks, p=0.02) and progression free survival (median 50.9 weeks vs 20.4 weeks, p=0.02) of AML1/ETO positive group were longer than those of negative group in AML. AML-M2 patients with AML1/ETO rearrangement had also a tendency of longer overall survival and progression free survival, although there was no significant difference between both group (median OS 82.4 weeks vs 15.6 weeks, p=0.07, median PFS 50.9 weeks vs 16.0 weeks, p=0.09). Conclusion: Our data suggest that AML1/ETO rearrangement is detected frequently in AML, especially M2, and is a favorable prognostic factor. Thus, molecular diagnostic approaches should be used routinely to identify patients with this genetic subtype of AML.(Korean J Med 61:650-659, 2001)

박경선,김유진,윤진영,경선영,안창혁,이상표,박정웅,정성환,Park, Kyeong Seon,Kim, Yu Jin,Yoon, Jin Young,Kyung, Sun Young,An, Chang Hyeok,Lee, Sang Pyo,Park, Jeong Woong,Jeong, Sung Hwan 대한결핵및호흡기학회 2008 Tuberculosis and Respiratory Diseases Vol.65 No.6

연구배경: 황사는 동북아시아에서 자연 발생하는 현상으로, 지름 $10{\mu}m$ 이하의 미세먼지(particulate matter 10, $PM_{10}$)를 다수 포함하여, 흡입하면 하부기관지 및 폐의 가스-교환부분까지 침착 가능하여 호흡기계에 손상을 일으킬 수 있다. 본 연구에서는 황사에 포함된 $PM_{10}$을 기관지상피세포에 작용시켜 활성산소 및 $NF{\kappa}B$, $TGF-{\beta}$, fibronectin이 증가 여부를 확인하고 섬유화의 신호경로를 규명하고자 하였다. 방 법: 공기포집기로 포집한 $PM_{10}$ 입자를 추출하여 기관지 상피세포인 WI-26 VA4 cells (KCLB)에 $PM_{10}$을 농도에 맞게 노출시켰다(0, 50, $100{\mu}g/ml$). ROS는 DCF-DA를 세포에 반응시킨 후 생성된 DCF를 FACScan을 이용해 측정하였다. $TGF-{\beta}$, fibronectin, $NF{\kappa}B$는 western blotting으로 분석하였다. 항산화제인 NAC를 이용하여 각 물질의 발현 억제 여부를 측정하였다. 결 과: $PM_{10}$을 가했을 때 대조군에 비하여 $50{\mu}g/ml$, $100{\mu}g/ml$에서 ROS, $TGF-{\beta}$, fibronectin, $NF{\kappa}B$ 발현이 유의하게 증가하였고, 항산화제인 NAC를 처리한 세포는 ROS, $TGF-{\beta}$, fibronectin, $NF{\kappa}B$의 발현이 $50{\mu}g/ml$, $100{\mu}g/ml$에서 유의하게 감소하였다. 결 론: 황사의 $PM_{10}$은 WI-26 VA4 cells에서 ROS 생성을 증가시키고 $NF-{\kappa}B$, $TGF-{\beta}$, fibronectin 생성을 증가시켜 섬유화에 기여할 것으로 사료된다. Background: Particulate matter may be toxic to human tissue. Ambient air particulate matter ${\leq}10{\mu}m$ in aerodynamic size ($PM_{10}$), which changes under different environmental conditions, is a complex mixture of organic and inorganic compounds. The Asian dust event caused by meteorological phenomena can also spread unique particulate matter in affected areas. We evaluated production of ROS, $TGF-{\beta}$, fibronectin, and $NF{\kappa}B$ by exposing normal epithelial cells to Asian dust particulate matter. Methods: Bronchial epithelial cells were exposed to 0, 50, ${\leq}100{\mu}g/ml$ of a suspension of $PM_{10}$ for 24 h. ROS were detected by measurement of DCF release from DCF-DA by FACScan. $TGF-{\beta}$, fibronectin, and $NF{\kappa}B$ were detected by western blotting. Results: $PM_{10}$ exposure increased the expression of $TGF-{\beta}$, fibronectin, and $NF{\kappa}B$. ROS production and $TGF-{\beta}$ levels were significantly higher with 50 or ${\leq}100{\mu}g/ml$ $PM_{10}$. Fibronectin and $NF{\kappa}B$ production were significantly higher after ${\leq}100{\mu}g/ml$ of $PM_{10}$. Conclusion: $PM_{10}$ from Asian dust particles might have fibrotic potential in bronchial epithelial cells via ROS induction after $PM_{10}$ exposure.

연구배경: 개흡충증은 한국에서 호산구증다증과 호산구성 폐질환을 일으키는 흔한 원인의 하나이다. 우리는 개흡충증에 의한 호산구성 폐질환의 특장을 분석하였다. 방법: 2001년 9월 1일부터 2006년 3월 30일까지 개회충 2기유충에 의한 호산구증다증으로 진단 받은 141명의 환자들을 대상으로 하였다. 본 연구를 위해 단순 흉부 방사선 촬영. 흉부 컴퓨터단층촬영, 기관지내시경, 기관지폐포세척술과 각종 혈액학적 검사를 시행하였다. 개회충증의 진단은 개회충 2기유충의 순수 분비배설 항원을 사용하였다. 결과: 141명의 환자 중 32명이 개회충에 의한 호산구성 폐질환으로 진단되었다. 젖빛유리양상이 컴퓨터단층촬영에서 지배적으로 23/32명(71.9%)이었다. 13/32명(40.6%)은 무작위적 구역적 분포를 보였다. 흉수액이 9/32명(28.1%)에서 관찰되었다. 28/32명(87.5%)이 호흡기 증상을 호소하였다. 11/32명(34.4%)은 호흡기 증상과 소화기 증상을 동시에 호소하였다. 12/32명(37.5%)에서 간에 국소의 저음영의 침윤을 보였다. 결론: 개회충에 의한 호산구성폐질환의 임상적, 방사선적 특성은 다발성의 결절성 또는 경화성의 젖빛유리음영이 양폐 상하엽에 무작위적 분포를 하는 것이다. 앞으로 우리나라에서 호산구 증다증과 폐침윤을 보이는 성인에서 감별진단을 위해 개회충증의 가능성을 고려해야 할 것으로 판단된다. Background: Toxocariasis is a common cause of eosinophilia and eosinophilic lung disease in Korea. We analyzed the characteristics of eosinophilic lung disease in toxocariasis. Method: One hundred and forty one patients with eosinophilia caused by a toxocara larval infection were evaluated from September 1, 2001 through March 30, 2006. The plain chest x-ray, chest CT(computed tomography), and bronchoalveolar larvage(BAL) were examined. A diagnosis of toxocariasis was made by ELISA using that secretory-excretory antigen from the T. canis larvae. Results: Toxocarial eosinophilic lung diseases was diagnosed in 32 out of 141 patients. Ground glass attenuation was the main feature on the CT scans in 23 out of 141 patients (71.9%). Thirteen patients (40.6%) had a random in zonal distribution on CT. Pleural effusion was observed in 9 patients (28.1%). Twenty eight patients (87.5%) complained of respiratory symptoms. Eleven patients (34.4%) had gastrointestinal symptoms and 12 patients (37.5%) had liver infiltration. Conclusions: The most common findings of the chest CT in patients with toxocariasis was a randomly distributed ground grass attenuation. A toxocara infection should be considered in a differential diagnosis of patients who exhibit pulmonary infiltration with eosinophilia in Korea. (Tuberc Respir Dis 2007; 62: 19-26)

Background/Aims: This study examined the clinical characteristics of patients with lung cancer who were diagnosed at the Gachon University of Medicine and Science Gil Hospital from January 2006 to December 2008. Methods: The lung cancer data were downloaded from the hospital medical information system using cancer registration information. The patient clinical characteristics were analyzed retrospectively. Results: A total of 713 patients were diagnosed with lung cancer. Their median age was 69 years, 78.1% were over 60 years old, and 73.1% and 58.2% were men and smokers, respectively. Adenocarcinoma (32.7%) was the most common histologic type, followed by squamous carcinoma (25.9%), unclassifiable non-small-cell lung cancer (NSCLC) (17.3%), and small-cell carcinoma (SCLC) (15.0%). In the NSCLC group, the stage at diagnosis was IA (1.5%), IB (5.6%), ⅡA (1.3%), ⅡB (4.3%), IIIA (5.4%), ⅢB (23.1%), Ⅳ (47.7%), and unknown (11.1%). In the SCLC group, 20.6% of the patients were in the limited stage, 76.6% were in the extensive stage, and 2.8% were unknown. The patients were treated by surgery (9.8%), concurrent chemoradiotherapy (6.7%), radiotherapy only (5.9%), chemotherapy (32.4%), or best supportive care only (29.7%). The median overall survival was 15.3 months (95% CI, 11.5~19.1). The median survival based on histology was adenocarcinoma (35.0 months), squamous (13.5 months), NSCLC (14.2 months), and SCLC (11.8 months) (p=0.0445). Conclusions: Adenocarcinoma was the most common histologic type at our institute. Most patients were over 60 years of age (78.1%) and had stage Ⅲ/Ⅳ (76.3%) cancer. The survival of patients with adenocarcinoma was longer than that for the other histological types. (Korean J Med 78:215-221, 2010)

연구배경: 발관 실패와 관련된 위험 인자를 살펴보고, 기관내 삽관의 합병증으로 인한 후두부 폐쇄와 PES로 인한 재삽관의 위험성을 발관 전에 미리 예측하기 위한 CLT 검사의 의의 및 제한점을 알아보고자 하였다. 방법: 24시간 이상 삽관과 인공 호흡기 치료 후 발관을 시도한 34명의 연속적인 환자들을 대상으로 발관 실패군에서 성공군과 차이를 보이는 인자를 살펴보고 CLT를 시행해서 PES와 재삽관을 예측하는 CLV, CLP의 기준값을 구하였다. 결과: 총 34명중 발관 실패는 6명(17.6%), PES는 3명(8.8%) 이었고 PES가 있던 3명은 모두 재삽관을 받았다. 발관 실패 환자에서 삽관 기간이 길었고, SAPS II score가 컸으며, 삽관 기간은 CLV, CLP와 역상관관계를 보였다. PES 양성 환자의 평균 CLV은 22.5±23.8㎖로 음성 환자의 233.3±147.1㎖보다 낮았고, CLP도 양성군에서 6.2±7.3%로 음성군의 44.3±24.7%보다 유의하게 낮았다. 가장 신뢰성 있는 CLV, CLP의 기준값은 50㎖, 14.7%였고 CLV의 민감도는 100%, 특이도 93.5%, 양성예측도 60%, 음성예측도 100%였고, CLP의 민감도는 100%, 특이도 87.1%, 양성예측도 42.9%, 음성예측도 100%였다. 결론: 삽관 기간이 길고 중증 질환 환자에서 발관 실패의 가능성이 높다. CLV, CLP가 감소되어 있을 경우 PES로 인한 재삽관 위험이 높아지므로 발관 시 주의가 필요하지만 발관의 불필요한 연기나 시도 자체에 대한 기준은 아닐 것으로 생각된다. Background: Extubation failure was associated with poor prognosis and high hospital mortality. Cuff leak test (CLT) has been proposed as a relatively simple method for detecting laryngeal obstruction that predispose toward postextubation stridor (PES) and reintubation. We examined the risk factors of extubation failure and evaluated the usefulness and limitation of CLT for predicting PES and reintubation. Methods: Thirty-four consecutive patients intubated more than 24 hours were examined. The subjects were evaluated daily for extubation readiness, and CLT was performed prior to extubation. Several parameters in the extubation success and failure group were compared. The accuracy and limitation of CLT were evaluated after choosing the thresholds values of the cuff leak volume (CLV) and percentage (CLP). Results: Of the 34 patients studied, 6 (17.6%) developed extubation failure and 3 (8.8%) were accompanied by PES. The patients who had extubation failure were more likely to have a longer duration of intubation and more severe illness. The patients who developed PES had a smaller cuff leak than the others: according to the CLV (22.5±23.8 vs 233.3±147.1㎖, p=0.020) or CLP (6.2±7.3 vs 44.3±24.7%, p=0.013). The best cut off values for the CLV and CLP were 50㎖ and 14.7%, respectively. The sensitivity, negative predictive value, and specificity of CLT were relatively high, but the positive predictive value was low. Conclusion: The likelihood of developing extubation failure increases with increasing severity of illness and duration of intubation. A low CLV or CLP (<50㎖ or 14.7%) is useful in identifying patients at risk of PES, but the CLT is not an absolute predictor and should not be used an indicator for delaying extubation.

Background: Dust clouds blown by the wind from the arid deserts of Mongolia and Northeast China are known as Asian dust storms. Ambient particulate matter with a diameter <10 μm (PM10) is associated with the exacerbation of respiratory diseases and increased mortality of heart and lung disease patients. The fibrotic effects of PM10 of Asian dust to pulmonary fibroblast cells are unknown. This study examined the production of reactive oxygen species (ROS), TGF-β, NF-κB, PDGF-α and Fibronectin in fibroblasts exposed to Asian dust particles. Methods: Air samples were collected using a high volume air sampler (Sibata model HV500F) with an air flow of 500 L/min for at least 6 hours. The MRC-5 cells were exposed to 0, 50 and 100 μg/mL of PM10 for 24 hours. ROS was detected by measuring the level of oxidized DCF using FACS. TGF-β, NF-κB, PDGF-α and fibronectin were detected by western blotting. Results: There was no increase in the ROS, TGF-β and PDGF-α levels in the MRC-5 cells exposed to PM10. The NF-κB level was higher in the MRC-5 cells exposed to 50 and 100 μg/mL of PM10 for 24 hours. The fibronectin level in the MRC-5 cells after 24 hours incubation with 50 μg/mL PM10 was significantly higher than the control group (PM10 50 μg/mL 113.27±8.65 of control, p=0.005). Conclusion: PM10 from Asian dust increases the activation of NF-κB and fibronectin expression in MRC-5 fibroblast cells.
