  • 폐기포는 폐 내부에 공기를 포함하는 공간으로 보통 1cm 이상의 크기와 2mm이하의 모발선 모양의 기포벽을 갖는다. 자연경과상 지속적으로 약화되는 양상을 보이고 자연소실 또는 호전되는 경우는 매우 드문 것으로 알려져 있다. 저자들은 임신중 발생한 속립성 결핵 환자에서 성인형 호흡곤란 증후군의 경과 후 발생한 다발성 폐기포가 자연소실된 1예를 관찰하였기에 보고하는 바이다.

  • A 33-year-old woman was presented with dyspnea and chest discomfort after indigesting approximately 500ml of oil paint brush washing fluid. Hypoxic symptoms and radiographic infiltrates rapidly progressed. The patient was intubated and received mechanical ventilation. Bronchoalveolar lavage and transbronchial lung biopsies were performed. The CT scan of the lung showed bilateral extensive pneumonitis with necrosis and the lung tissue pathologic findings showed diffuse alveolar damage with extensive necrosis and numerous lipid-laden macrophages. After intensive medical care with mechanical ventilation, her symptoms and radiological findings improved.

  • A 62-year-old male was admitted for evaluation of a mass shadow on chest film. Chest PA showed $7{\times}5cm$ lobulated homogenous mass in right upper medial area of lung. On chest computed tomography, there was a large irregularly lobulated mass with central necrotic low density area in apical segment of right upper lobe. Right upper lobectomy of the lung was performed. Partial adhesion to parietal pleura of posterior mediastinum and severe adhesion to right upper apicoposterior segment was found during the operation. Microscopic and ultrastructural studies(including immunocytochemical stains) of the mass revealed malignant fibrous histiocytoma.

  • Three cases of double primary lung cancer occured synchronously are reported with brief review of literature. The incidence of multiple primary lung cancer relatively rare but may become increasingly prevalent as early detection techinque and cancer therapy has improved. The patients were a 67, 69, and 65-year-old men with doulbe primary lung cancer of different cell type or same cell type with other bronchus origin (squamous cell+small cell, squamous cell+squamous cell, squamous cell+bronchioloaveolar cell) were identified with flexible bronchofiberoscopic biopsies. More careful diagnostic evaluation and management are thought to be necessary.

  • Lung cancer ranks first in cancer mortality in Korea and cancer incidence in Korean men. More than half of Korean lung cancer patients undergo chemotherapy, including adjuvant therapy. Cytotoxic agents, targeted therapy, and immune checkpoint inhibitors are used in chemotherapy according to the biopsy and genetic test results. Among chemotherapy, the one that has developed rapidly is targeted therapy. The National Comprehensive Cancer Network (NCCN) guidelines have been updated recently for targeted therapy of multiple gene mutations, and targeted therapy is used not only for chemotherapy but also for adjuvant therapy. While previously targeted therapies have been developed for common genetic mutations, recently targeted therapies have been developed to overcome uncommon mutations or drug resistance that have occurred since previous targeted therapy. Therefore, this study describes recent, rapidly developing targeted therapies.

  • Objectives: In this study, an evaluation of the working environment of furnace workers was performed and the work-relatedness of the occupational diseases were examined Methods: In this study, two electric furnaces at a single casting business site producing manganese-based iron alloy were selected, and occupational exposures to hazardous substances were evaluated for furnace workers and furnace worker assistants. Results: As a result, total dust concentration were $0.407{\sim}3.001mg/m^3$ and respirable dust concentration were $0.196{\sim}0.584mg/m^3$. The highest concentration of crystalline silica was $0.079mg/m^3$ In the case of Masato and Sosuckwhoi crystalline silica, they contained 90.85% and 4.17% respectively. Manganese concentration was the highest at a $0.205mg/m^3$ maximum. The average of black carbon is $11.56{\mu}g/m^3$ and the maximum concentration is $604.23{\mu}g/m^3$. PAHs concentration was the highest at a $78.301{\mu}g/m^3$ of naphthalene. The concentration of carbon monoxide was 18.82 ppm(total average 3.89 ppm) during pouring, and the maximum is 131 ppm. The formaldehyde concentration was 0.003 to 0.007 ppm. Conclusions: It seems that conditions in the past were worse, since casting has recently been performed only twice per day for about 20 minutes, reducing the amount of pouring, and local exhaust systems have been installed one-by-one. In addition, it was judged that the past exposure levels were higher considering the points measured on the back-side due to the risk of damage to the individual samples. It was found that operators could be exposed to high concentrations of crystalline silica, and that they were also exposed to high concentrations of metal(fume) and carbon monoxide during pouring. Therefore, there is a risk that occupational diseases such as lung cancer and COPD may occur with long-term work in such a process.

  • 연구배경 : 폐동맥 색전증은 여러 다양한 상황에서 발생할 수 있으며, 비특이적인 증상과 징후로 인하여 진단이 지연될 수 있으며, 이로 인하여 불행한 결과를 초래할 수 있고, 따라서 조기 진단과 적절한 치료가 필수적인 응급 질환이다. 폐관류주사는 이 질환의 진단에 유용한 검사법이며, 음성 결과는 이 질환을 배재시킬 수 있으나, 관류 결손이 언제나 배제시킬 수 있으나, 관류 결손이 언제나 폐동맥 색전증을 의미하는 것은 아니다. 따라서 폐관뷰주사검사의 해석에 있어 보다 유용한 정보를 얻기 위하여 폐관류주사상 폐동맥 색전증소견을 보이는 환자들에 대한 임상적 고찰의 필요성이 제기되었다. 방 법 : 1996년 1월 1일부터 1997년 7월 31일 사이에 서울대학교병원에 입원하여 임상적으로 폐동맥색전증이 의심되어 시행한 폐관류주사상 폐동맥 색전증의 소견을 보인 49예를 대상으로 그들의 임상기록을 통한 후향적 조사를 시행하였다. 결 과 : 입원시 폐동맥 색전종이 의심되었던 환자군에서의 최초 임상 진단은 폐동맥 색전증, 심장 질환, 폐렴의 순이었으며, 입원 중 폐동맥 색전증의 발생이 의심되었던 환자군에서의 기저 질환은 약성 종양, 두강내 출혈, 패혈증, 전신성 홍반성 낭창 등의 순이었다. 유발 인자로는 수술, 악성 종양, 부동화, 결합조직 질환, 심장 질환, 고령(>70세), 임신 및 골반내 질환, 신장 질환 등의 순이었다. HPPE가 40예(26.8%), IPPE가 21예(14.1%), LPPE가 88예 (59.1%) 였고, 이 중 치료를 시행한 경우는 HPPE가 34예(85%), IPPE가 9예(42.9%)였으며, LPPE소견을 보인 환자 중 치료를 시행한 경우는 없었다. 치료로는 heparin과 warfarin을 선택한 경우가 39예(79.7%)로 대부분을 차지하였고, 색전 제거술 2예(4.1%), 혈전 용해제와 IVC filter가 각 1예 (2.0%)씩이었으며, 우강내 출혈(3예), 대량 출혈 (2예), 증상의 소실(1예) 등을 이유로 치료를 시행하지 않은 경우가 6예(12.2%)였다. 추적 관찰은 34예(69.4%)에서 가능하였고, 이 중 재발은 5예(10.2% )에서 발생하였으며, 3예에서는 항응고제의 조기 중단에 의한 것이었고, 2예는 유발 인자의 재발에 의한 것이었다. 조사 대상 중 사망은 16예(32.6%)였으나, 이 중 폐동맥 색전증과 관련된 사망은 1예(2.04%)로 진단 후 혈전 용해제 투여 직전에 사망하였다. 결론 : 폐동맥 색전증 환자의 예후 개선을 위하여 증상 발생부터 진단까지의 소요 기간의 단축, 즉 이 질환에 대한 의심이 필요하리라 사료된다.
