Herein we report the case of a 71-year-old woman who complained of fatigue and enlarged right axillary lymph nodes for 18 months. At her first visit, her chest X-ray showed diffuse nodular opacities in both lung fields. Initial excisional biopsy of the axillary lymph nodes showed granulomatous lesions and acid fast bacilli were seen on Ziehl-Neelsen staining. However, even after 15 months of anti-tuberculosis (TB) medication, her right axillary lymph nodes were enlarged. We re-performed an excisional biopsy of the nodes, which showed Hodgkin's lymphoma (HL). A retrograde review of the biopsy before anti-tuberculous medication, revealed HL coexisting with TB. HL and TB cause difficulties in differential diagnosis due to similarities in clinical course, imaging procedures and histopathological analysis of the involved tissue. Therefore, it is important to consider the possibility of concurrent HL and TB when patients who undergo treatment for TB or chemotherapy for lymphoma complain of persistent systemic symptoms or enlarged lymph nodes.

The pleura is known as an end target organ of exposure to toxic environmental materials such as fine particulate matter and asbestos. Moreover, long-term exposure to hazardous materials can eventually lead to fatal lung disease such as diffuse pleural fibrosis or mesothelioma. Chest computed tomography (CT) and ultrasound are gold standard imaging modalities for detection of advanced pleural disease. However, a diagnostic tool for early detection of pleural reaction has not been developed yet due to difficulties in imaging ultra-fine structure of the pleura. Optical coherence tomography (OCT), which provides cross-sectional images of micro tissue structures at a resolution of 2-10 μm, can image the mesothelium with a thickness of ~100 μm and therefore enables investigation of the early pleural reaction. In this study, we induced the early pleural reaction according to a time sequence after pleurodesis using talc, which has been widely used in the clinical field. The pleural reaction in talc grouped according to the time sequence (1st, 2nd, 4th weeks) showed a significant thickening (average thickness: 45 ± 7.5 μm, 80 ± 10.7 μm, 90 ± 12.5 μm), while the pleural reaction in sham and normal groups showed pleural change from normal to minimal thickening (average thickness: 16 ± 5.5 μm, 17 ± 4.5 μm, 15 ± 6.5 μm, and 12 ± 7.5 μm, 13 ± 2.5 μm, 12 ± 3.5 μm). The measurement of pleural reaction by pathologic examinations was well-matched with the measurement by OCT images. This is the first study for measuring the thickness of pleural reactions using a biophotonic modality such as OCT. Our results showed that OCT can be useful for evaluating the early pleural reaction.

Objective: To assess the safety and effectiveness of a mouth-rinse with G-CSF (JiSaiXin, produced by NCPC Biotechnology Co., Ltd) in treating patients with chemotherapy-induced oral mucositis (CIM). Method: A consecutive cohort of patients with advanced cancers and CIM were treated with mouth-rinse G-CSF. All chemotherapy for patients with advanced cancers was adopted from regimens suggested by NCCN guidelines. The mouth-rinse with G-CSF at a dose of 150-300ug plus 100ml-500ml normal saline was started from the time of oral mucositis was confirmed and continuously used for at least 7 days as one course. After at least two courses of treatment, safety and efficacy were evaluated. Results: There were 7 female and 7 male patients with advanced cancer and CIM recruited into this study, including 5 with colorectal, 2 with lung, 1 patient with gastric, 1 with cervical and 1 with pancreatic cancer, as well as 2 patients with diffuse large B cell lymphomas, 1 with nasopharyngeal and 1 with gastric cancer. The median age was 57 (41-79) years. Grade 1 to 2 myelosuppression was observed in 3/14 patients, and Grade 4 myelosuppression in 1/14. Adverse effects on the gastrointestinal tract were documented in 5/14 patients, and were Grade 1 to Grade 3. No treatment related death was documented. Regarding CIM, the median response time to mouth rinse of G-CSF was 2 (1-5) days, and all patients with CIM demonstrated a positive response. Conclusions: Mouth-rinse with G-CSF proved to be safe and effective in treating patients with advanced cancers and CIM. However, further randomized controlled studies should be conducted to clarify the effectiveness of this treatment with other lesions.

Background: To evaluate chest CT findings of pandemic influenza A/H1N1 pneumonia without co-infection. Methods: Among 56 patients diagnosed with pandemic influenza A/H1N1 pneumonia, chest CT was obtained in 22 between October 2009 and Februrary 2010. Since two patients were co-infected with bacteria, the other twenty were evaluated. Predominant parenchymal patterns were categorized into consolidation, ground glass opacity (GGO), and mixed patterns. Distribution of parenchymal abnormalities was assessed. Results: Median age was 46.5 years. The CURB-65 score, which is the scoring system for severity of community acquired pneumonia, had a median of 1. Median duration of symptoms was 3 days. All had abnormal chest x-ray findings. The median number of days after the hospital visit that Chest CT was performed was 1. The reasons for chest CT performance were radiographic findings unusual for pneumonia (n=13) and unexplained dyspnea (n=7). GGO was the most predominant pattern on CT (n=13, 65.0%). Parenchymal abnormalities were observed in both lungs in 13 cases and were more extensive in the lower lung zone than the upper. Central and peripheral distributions were identified in ten and nine cases, respectively. One showed diffuse distribution. Peribronchial wall thickening was found in 16 cases. Centrilobular branching nodules (n=7), interlobular septal thickening (n=4), atelectasis (n=1), pleural effusion (n=5), enlarged hilar and mediastinal lymph nodes (n=6 and n=7) were also noted. Conclusion: Patchy and bilateral GGO along bronchi with predominant involvement of lower lungs are the most common chest CT findings of pandemic influenza A/H1N1 pneumonia.

본 연구에서는 호흡기를 통한 미세먼지 노출이 과민성 천식 마우스 간 조직의 산화적 스트레스에 미치는 영향을 확인하였으며, 이에 대한 괭생이모자반 추출물의 항산화 효과를 평가하였다. 세포막 지질과산화의 최종 산물인 MDA와 항산화 효소인 catalase가 미세먼지 흡입 과민성 천식 마우스의 간 조직에서 증가하였으며 SHE 병행 투여 시 감소하였다. 또한 미세먼지 흡입 과민성 천식 마우스의 간 조직에서 증가한 산화적 DNA 손상 수복효소인 OGG1은 SHE의 병행 투여 시 감소하였다. 결론적으로 괭생이모자반이 미세먼지 흡입 과민성 천식 마우스의 간 조직에서 산화적 스트레스 및 산화적 DNA 손상에 대해 항산화 효과를 나타냈다. 따라서 괭생이모자반이 미세먼지에 의한 산화적 손상을 보호하는 식품 소재로서 활용될 수 있을 것으로 기대된다.

Paclitaxel has been widely used for treating many solid tumors. Although colonic toxicity is an unusual complication of paclitaxel-based chemotherapy, the reported toxicities include pseudomembranous colitis, neutropenic enterocolitis and on rare occasions ischemic colitis. $Genexol-PM^{(R)}$, which is a recently developed cremophor-free, polymeric micelle-formulated paclitaxel, has shown a more potent antitumor effect because it can increase the usual dose of paclitaxel due to that $Genexol-PM^{(R)}$ does not include the toxic cremophor compound. We report here on a case of a 57-year-old man with advanced non-small cell lung cancer and who developed ischemic colitis after chemotherapy with $Genexol-PM^{(R)}$ and cisplatin. He complained of hematochezia with abdominal pain on the left lower quadrant. Colonoscopy revealed diffuse mucosal hemorrhage and edema from the sigmoid colon to the splenic flexure. After bowel rest, he recovered from his symptoms and the follow-up colonoscopic findings showed that the mucosa was healing. Since then, he was treated with pemetrexed monotherapy instead of a paclitaxel compound and platinum.

Immunoglobulin (Ig) G4-related disease is a recently recognized systemic fibroinflammatory condition characterized by a lymphoplasmacytic infiltrate rich in IgG4-positive plasma cells with elevated circulating levels of IgG4. The disease can either be localized to one or two organs, or present as diffuse multi-organ disease. Furthermore, lesions in different organs can present simultaneously or metachronously. In the pulmonary manefestations, lesions associated with IgG4-related disease have been described in the lung parenchyma, airways and pleura, as well as the mediastinum. We report a case of IgG4-related disease presenting as massive pleural effusion and thrombophlebitis.

Goodpasture 증후군은 원인 불명의 병인을 가진 드문 질환으로 질병의 경과가 급속히 진행하므로 조기에 진단을 하여 조기에 치료방법을 결정하는 것이 질병의 예후와 큰 연관성을 가진다. 크론씨 병에서 혈관염에 의한 폐 합병증을 보이는 경우는 드물어 국내에는 이와 관련된 보고가 없었으며, 17년 전 항문 누공과 농양으로 크론씨 병으로 진단 받고 10년 전 전대장 절제술을 시행한 이후 추적 관찰하는 도중 발견된 Goodpasture 증후군 1예를 경험하였기에 문헌고찰과 함께 보고하는 바이다.
