So far more than 350 drugs have been reported to be the cause for lung injury and the incidence tends to increase. Although infiltrative lung disease is the most common pattern of drug-induced lung injury, it can appear in the form of alveolar changes, vasculitis and other injury. Herbal medicine also has been known as a cause for interstitial pneumonitis, but it is difficult to identify the key herbal medicine because of the complex components of the contents. Till date, there is no report of pneumonitis caused by golden thread. Here we report a case of a 54-year-old male who developed interstitial pneumonitis with acute liver injury caused by herbal medicine made from golden thread.

Objective: To report a fatal case of Multidrug-resistant Acinetobacter baumannii (MDR-AB) in a patient with interstitial lung disease (ILD) on high-dose glucocorticoids. Case Summary: A 66-year-old man with a history of coniosis was transferred to the hospital with progressive cough and sputum production. This patient has been diagnosed with pneumonia and ILD on admission, requires antimicrobial therapy and systemic immunosuppressants. He received high dose of methylprednisolone and cyclophosphamide for ILD as well as ceftriaxone and azithromycin for pneumonia. On day 7 in the intensive care units (ICUs), patient had fever and leukocytosis, thus antimicrobials were switched to piperacillin. After 13 days in the ICU, Acinetobacter baumannii and methicillin-resistant Staphylococcus aureus (MRSA) were isolated on transtracheal aspirate (TTA) and meropenem was initiated. However, it was revealed a multidrug-resistant Acinetobacter baumannii (MDR-AB) species, resistant to carbapenem. Patient was administered colistin but expired due to septic shock on day 84. Discussion: Systemic immunosuppressive therapy can result in infections that may compromise patient's survival. MDR-AB has emerged as a serious cause of nosocomial infections in immunocompromised patients. MDR-AB is resistant to most standard antimicrobials and therapeutic options are limited. Conclusion: We report our recent experience with a fatal MDR-AB pneumonia in a patient with ILD, who had to be treated with high dose glucocorticoids and immunosuppressnts.

The combination therapy of pegylated interferon and ribavirin is the mainstay of treatment for chronic hepatitis C patients. Anti-viral therapy is commonly associated with side effects such as headache, fever, myalgia, and arthralgia. However, anti-viral therapy can continue because these side effects are mostly mild and can be improved with supportive management. Anti-viral therapy should be stopped promptly if serious side effects, such as interstitial pneumonitis or hemolytic anemia occur, although those serious side effects are rare. There were a few case reports of interferon-related interstitial pneumonitis worldwide. In Korea, one atypical case report of interstitial pneumonitis has been reported, which followed the combination therapy of interferon-alpha and ribavirin in a patient with chronic hepatitis C. We present a case of interstitial pneumonitis and pancytopenia following the combination therapy of pegylated interferon and ribavirin in a patient with chronic hepatitis C.

Bronchiolitis obliterans organizing pneumonia(BOOP) is a type of diffuse interstitial lung disease that has emerged in the past decade as an important cause of acute respiratory illness in adult. Clinically, the entity usually starts with a subacute influenza-like illness, followed by cough, progressive dyspnea, and weight loss. Organized inflammatory polypoid materials predominantly affecting distal bronchioles, alveolar ducts, and peribronchial alveolar spaces are a key pathologic findings. BOOP is characterized by a good response to glucocorticoid and an excellent prognosis. However, there is a subset of BOOP who presents with a fulminant course leading to death or chronic severe fibrosis with marked impairment of lung function. Recently, we have experienced a case of rapidly progressive BOOP, diagnosed by open lung biopsy and showed a reluctant response to corticosteroid.

Background : Steroid therapy has been shown to improve the clinical outcome in acute respiratory distress syndrome (ARDS) patients with histological evidence of fibroproliferation in the lung tissue and no identifiable source of infection. Because the histopathological features of acute interstitial pneumonia(AIP) are identical with that of ARDS, early steroid therapy was used in AIP patients who had histological evidence of fibroproliferation in the lung tissue and no identifiable source of infection. We analyzed seven years of our experience to evaluate the efficacy of early steroid therapy in AIP. Materials and Methods : A retrospective review was performed on AIP patients who received steroid therapy within 7 days of mechanical ventilatory support in Dankook university Hospital between May 1995 and May 2002. AIP was diagnosed clinically by ARDS without a known cause of the etiology and pathologically by a lung biopsy showing a fibroproliferative stage of diffuse alveolar damage. The clinical response and physiologic parameters were evaluated during steroid therapy. Results : Five AIP patients received intravenous methylprednisolone (1-2 mg/kg every 6 hours) after $0.6{\pm}1.7$ days of mechanical ventilatory support. Lung biopsies were performed after $1.8{\pm}1.4$ days of mechanical ventilatory support. Four patients(80%) survived and were extubated after $2.8{\pm}0.4$ days of steroid therapy with improvement in the $PaO_2/FiO_2$ ratio ($127.4{\pm}10.0$ at day 0 to $223.8{\pm}37.6$ at day 7) by steroid therapy. However, one patient(20%) died of respiratory failure after 15 days of steroid therapy. Conclusion : Early steroid therapy sppears to be beneficial in AIP patients without evidence of infection. However, as our study group was too small, further large scale studies to define the effectiveness of steroids are required.

Toxic gases and soot deposition as a consequence of smoke inhalation can cause direct injury to the upper and lower airways and even to the lung parenchyma. A delay in proper and prompt therapy can be detrimental to critically ill burn patients with an inhalation injury. Therefore, serial chest radiography is an important diagnostic tool for pulmonary complications during treatment. The radiographic findings of the chest include normal, consolidation, interstitial and alveolar infiltrates, peribronchial thickening, atelectasis, cardiogenic and non-cardiogenic pulmonary edema, and a pneumothorax as acute complications of smoke inhalation. In addition, bronchiectasis, bronchiolitis obliterans and pulmonary fibrosis can occur as late complications. We encountered a case of 44-year-old male who presented with acute lung injury after an inhalation injury. He required endotracheal intubation and mechanical ventilation due to respiratory failure. He was managed successfully with conservative treatment. Later, a cavitary lesion of the left upper lobe was observed on the chest radiography and computed tomography, which was complicated by massive hemoptysis during the follow-up. However, the cavitary lesion disappeared spontaneously without any clinical consequences.

An elevated serum CA19-9 level is an indication of pancreatic and biliary tract cancer. However, it has recently become known that nonmalignant gastrointestinal diseases and a variety of nonmalignant respiratory diseases, such as idiopathic interstial pneumonia, collagen vascular disease associated lung diseases, diffuse panbronchiolitis and bronchiectasis, can also show an elevated serum CA19-9 level. We recently encountered a case of bronchiectasis with persistently elevated serum CA19-9, but without any evidence of malignant disease in endoscopic retrograde pancreatocholangiography, abdominal computed tomography, and positron emission tomography. After serial follow-up of 3 years and 10 months, there was still no evidence of cancer. It is believed that the elevated serum CA19-9 level was due to bronchiectasis. An elevated serum CA19-9 level should be interpreted carefully with the patients' clinical condition.

Background: Surgical closure of the PDA in premature infants with complications or contraindications to indomethacin use, or recurrence of symptomatic PDA is a safe and effective procedure with low operative risk and minimal complications. Material and Method: From April 1996 to August 1998, 11 premature infants with body weight under 1.5 kg at operation underwent operation for a symptomatic PDA (male:5, female: 6). Associated dise ases were congenital heart disease(7), hyaline membrane disease(6), intraventricular hemor rhage(4), pneumonia(4), pneumothorax(3), hyperbilirubinemia(2), necrotizing enterocolitis(2), renal failure(1), epilepsy(1), and hydrocephalus(1). Surgical techniques are hemoclipping(8) and ligation(3). The size of PDA was 3~6 mm (5.0$\pm$1.2). Result: Systolic and diastolic blood pressure rised and heart rates decreased after PDA closure. ABGA improved postoperatively. There were no surgical complications. Six infants with improved ABGA data were weaned from mechanical ventilatory support. The follow-up durations after discharge were 3 month to 12 month. Five deaths were not related to operation. The causes of death were hyaline membrane disease(2), bronchopulmonary dysplasia with pneumonia(1), sepsis(1), and con gestive heart failure with respiratory distress syndrome(1). Conclusion: Early operative closure is the treatment of choice in most premature infants with a hemodynamically significant shunt(PDA), recurrence of symptomatic PDA, complications of Indomethacin, or contraindi cations to Indomethacin.

투명 전도성 산화물(transparent conductive oxide: TCO) 박막은 높은 투과율과 낮은 비저항 덕분에 LCD (liquid crystal display), PDP (plasma display panel), OLED (organic light emitting display) 등 평판 디스플레이에 널리 사용되고 있다. 현재 양산되고 있는 ITO (indium tin oxide)는 90% 이상의 높은 투과율과 우수한 전도성으로 인해 TCO 박막 가운데서 디스플레이 산업에서 가장 널리 쓰이고 있다. 그런데, ITO의 인듐산화물에 의한 간질성 폐렴(interstitial pneumonia)의 유발 위험이 있다든가, 인듐의 매장량이 적어 원자재 가격이 비싼 단점도 가지고 있다. 이에 최근 ITO를 대체할 수 있는 TCO물질로 많은 연구가 이루어지고 있는데, 특히 AZO (aluminum-doped zinc oxide)는 그 중 대표적인 대체물질로서 독성이 없고 가격도 저렴하여 많은 관심이 증폭되고 있다. 현재 AZO는 sol-gel 방법이나 CVD (chemical vapor deposition) 또는 스퍼터링 방법 등으로 증착되고 있다. 본 연구에서는 두 개의 이종타겟(hetero target)을 장착한 대향 타겟 스퍼터링(facing target sputtering: FTS) 장치를 사용하여 AZO 박막을 제작한다. 기존의 여러 증착법과 달리, FTS 장치는 두 타겟 사이에 형성되는 플라즈마 내의 ${\gamma}$-전자를 구속하게 되며, 낮은 가스 압력에서 고밀도 플라즈마가 생성되어 빠른 증착 속도와 안정적인 방전을 유지한 상태에서 박막을 증착할 수가 있다. 또한 기판과 플라즈마가 이격되어 있어 높은 에너지를 갖는 입자들의 기판 충돌을 억제할 수 있는 장점들을 갖는다. 이종 타겟인 ZnO와 Al2O3를 사용하고 각 타겟에 인가되는 파워 변화를 통해 AZO 박막 내 Al2O3의 성분비를 조절하였다. ZnO 타겟의 증착 파워를 100 W로 고정할 경우, Al2O3 타겟의 증착 파워가 (50~90) W으로 실험을 하였으며, Al2O3 타겟의 증착 파워가 70 W일 때 AZO 박막의 Al2O3 성분비는 2.02 wt.%이며 박막의 비저항 값은 $5{\times}10^{-4}{\Omega}{\cdot}cm$로 최소값을 보였다. 이러한 비저항의 변화는 파워에 따른 AZO 박막의 캐리어 이동도(Hall mobility)와 캐리어의 농도(Carrier Concentration)의 변화와 밀접한 관계가 있음을 보여주며, 특히 AZO 박막의 캐리어 농도와 캐리어 이동도는 AZO 박막을 형성하고 있는 결정립의 크기에 의존하는 것이 X-선 회절 패턴과 SEM으로부터 확인되었다. 특히, 본 연구에서는 두 개의 이종 타겟(hetero target) Al2O3와 ZnO를 장착하고 각각의 파워를 변화시켜 도핑 량을 조절할 수는 대향 타겟 스퍼터링(FTS: facing-target sputtering) 방법을 이용하여 제작된 AZO 박막에 대해 전기적, 광학적 및 구조적 특성을 분석하고 ITO의 대체물로서의 가능성을 검토하고자 한다.
