배경: 간질성 폐렴(IP)은 폐암의 발생과 깊은 관련이 있으나 수술 후 경과에 미치는 영향은 아직 밝혀진 바 없다. 본 연구의 목적은 술전 간질성 폐렴과 수술 후 급성 호흡부전의 발생과의 관련성을 알아보기 위한 것이다. 대상 및 방법: 1997년 1월부터 2005년 3월까지 가톨릭대학교 의과대학 부속병원에서 근치적 수술을 시행받은 원발성 폐암환자 672예를 대상으로 후향적인 검토를 시행하였다. 수술 전 흉부 HRCT소견이나 수술 표본의 병리조직 판독서에서 간질성 폐렴이 확인된 환자들을 간질성 폐렴(IP)군으로 구분하여, 비합병(non-IP)군과의 사이에 수술 전 검사치와 암 관련 사항들을 비교 분석하였다. 또한 IP군에서는 급성 호흡부전의 발생군과 비발생군 사이에서 급성 호흡부전의 발생에 영향을 줄 수 있는 상이점들을 분석하였다. 결과: 근치적 수술을 시행 받은 672예 중 28예(4.2%)에서 수술 후 급성 호흡부전증이 합병되었으며, 672예 중 수술 전에 IP의 동반이 확인되었던 증례는 53예(7.9%)였다. IP 동반례에서는 6예(11.3%)에서 수술 후 급성 호흡부전증이 합병되었으며, IP가 없었던 619예에서는 22예(3.6%)에서 합병되었다. 급성 호흡부전증의 합병환자 28예 중 21예에서 사망하여 사망률은 75%였다. 결론: 간질성 폐렴은 폐암 수술 후 급성 호흡부전의 발생과 관련이 있다고 생각되었다.

Background: Pulmonary tuberculosis (TB), requiring the intensive care unit (ICU) care, has been a high-mortality condition until now. In the present study, we aimed to investigate clinical features and parameters associated with TB mortality. Methods: From August 2003 to December 2008, patients with microbiologically or histologically confirmed pulmonary TB then admitted to the ICU, were retrospectively enrolled into the study. Upon enrollment, their medical records were reviewed. Results: Forty three patients (30 males, 13 females) were included and their mean age was 63.8 years (range: 17~87 years). Twelve patients died, an overall in-hospital mortality of 27.8%. The main reason for the ICU care was dyspnea or hypoxemia requiring mechanical ventilation (n=17). Other diagnoses for ICU care were hemoptysis, monitoring after procedures, neurologic dysfunction, shock, and gastrointestinal bleeding. On univariate analysis, the factors affecting the mortality were malnutrition-related parameters including low body mass index, hypoalbuminemia, lymphocytopenia, and hypocholersterolemia, as well as severity-related variables such as high acute physiology and chronic health evaluation (APACHE) score, number of involved lobes, and high C-reactive protein. In addition, respiratory failure requiring mechanical ventilation and acute respiratory distress syndrome contributed to patient fatality. It was shown on multivariate analysis that respiratory failure and hypoalbuminemia were significantly independent variables associated with the mortality. Conclusion: Acute respiratory failure is the most common reason for the ICU care and also the most important factor in predicting poor outcome. In addition, our data suggest that the parameters associated with malnutrition could be possible factors contributing to mortality.

Extracorporeal Membrane Oxygenation (ECMO) support to tissue oxygenation has been shown to improve survival in patients with life threatening respiratory distress syndrome or cardiac failure. Extracorporeal life support such as ECMO, including extracorporeal $CO_2$ removal ($ECCO_2R$), is used as temporary support until successful recovery of organs. A recently published multicentre randomized controlled trial, known as the CESAR (conventional ventilation or extracorporeal membrane oxygenation for severe adult respiratory failure) trial, was the first trial to demonstrate the utility of ECMO in acute respiratory distress syndrome (ARDS). During the 2009 influenza A (H1N1) pandemic, there were many reports of patients with severe ARDS related to H1N1 infection treated with ECMO. These reports revealed a high survival rate and effectiveness of ECMO. In this review, we explain the indication of ECMO clinical application, the practical types of ECMO, and complications associated with ECMO. In addition, we explain recent new ECMO technology and management of patients during ECMO support.

Coronavirus disease 2019 (COVID-19) exhibits various symptoms, ranging from asymptomatic to severe pneumonia or death. The major features of patients in severe COVID-19 are the dysregulation of cytokine secretion, pneumonia, and acute lung injury. Consequently, it leads to acute respiratory distress syndrome, disseminated intravascular coagulation, multiple organ failure, and death. Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the causative virus of COVID-19, influences nucleotide-binding oligomerization domain, leucine-rich repeat, and pyrin domain containing 3 (NLRP3), the sensor of inflammasomes, directly or indirectly, culminating in the assembly of NLRP3 inflammasome and activation of inflammatory caspases, which induce the inflammatory disruption in severe COVID-19. Accordingly, the target therapeutics for inflammasome has attracted attention as a treatment for COVID-19. Korean Red Ginseng (KRG) inhibits several inflammatory responses, including the NLRP3 inflammasome signaling. This review discusses the role of KRG in the treatment and prevention of COVID-19 based on its anti-NLRP3 inflammasome efficacy.

Background: One to three percent of cases of acute tuberculosis (TB) require monitoring in the intensive care unit (ICU). The purpose of this study is to establish and determine the mortality rate and discuss the causes of high mortality in these cases, and to evaluate the clinical and laboratory findings of TB patients admitted to the pulmonary ICU. Methods: The data of patients admitted to the ICU of Yedikule Chest Diseases and Chest Surgery Education and Research Hospital due to active TB were retrospectively evaluated. Demographic characteristics, medical history, and clinical and laboratory findings were evaluated. Results: Thirty-five TB patients (27 males) with a median age of 47 years were included, of whom 20 died within 30 days (57%). The Acute Physiology and Chronic Health Evaluation II (APACHE II) and Sequential Organ Failure Assessment (SOFA) scores were significantly higher, and albumin and $PaO_2/FIO_2$ levels were significantly lower, and shock, multiple organ failure, the need for invasive mechanical ventilation and drug resistance were more common in the patients who died. The mortality risk was 7.58 times higher in the patients requiring invasive mechanical ventilation. The SOFA score alone was a significant risk factor affecting survival. Conclusion: The survival rate is low in cases of tuberculosis treated in an ICU. The predictors of mortality include the requirement of invasive mechanical ventilation and multiple organ failure. Another factor specific to TB patients is the presence of drug resistance, which should be taken seriously in countries where there is a high incidence of the disease. Finding new variables that can be established with new prospective studies may help to decrease the high mortality rate.

A 59-year-old man presented with acute dyspnea following sudden productive cough and expectoration of a full cup of "blood-tinged" sputum. He had been diagnosed with hepatitis B virus-related hepatocellular carcinoma and had received transarterial chemoembolization 5 years ago for a 20-cm hepatic mass; he denied any history of hematemesis and the last esophagogastroduodenoscopy from a year ago showed absence of varix. Chest computed tomography (CT) with angiography showed new appearance of right basal lung consolidation but no bleeding focus. Despite the use of systemic antibiotics, the patient developed respiratory failure on day 7 of hospitalization. After intubation, a massive amount of brown sputum with anchovy-paste-like consistency was suctioned via the endotracheal tube. Bronchoscopic toileting was performed and the patient was extubated. In the ward, he continued to expectorate the brown sputum. On day 25 of hospitalization, a repeat CT scan showed simultaneous disappearance of the pneumonic consolidation and the necrotic fluid within the hepatic mass, suggesting the presence of a fistula. He has continued to receive systemic antibiotics, sorafenib, and entecavir, and follow up by respiratory and hepato-oncology specialists.

Care of patients with sepsis has improved over the last decade. However, in the recent two years, there was no significant progress in the development of a new drug for critically ill patients. In January 2011, it was announced that the worldwide phase 3 randomized trial of a novel anti-Toll-like receptor-4 compound, eritoran tetrasodium, had failed to demonstrate an improvement in the mortality of patients with severe sepsis. In October 2011, Xigris (drotrecogin alfa, a recombinant activated protein C) was withdrawn from the market following the failure of its worldwide trial that had attempted to demonstrate improved outcome. These announcements were disappointing. The recent failure of 2 promising drugs to further reduce mortality suggests that new approaches are needed. A study was published showing that sepsis can be associated to a state of immunosuppression and loss of immune function in human. However, the timing, incidence, and nature of the immunosuppression remain poorly characterized, especially in humans. This emphasizes the need for a better understanding of sepsis as well as new therapeutic strategies. Many clinical experiences of the extracorporeal membrane oxygenator (ECMO) treatment for adult acute respiratory distress syndrome (ARDS) patients, which is caused by the H1N1 influenza A virus, were reported. The use of ECMO in severe respiratory failure, particularly in the treatment of adult ARDS, is occurring more commonly.

Paraquat, one of the potent herbicides, causes fatal damage to many vital organs, when orally ingested, resulting in circulatory failure, respiratory distress syndrome, and a few other serious problems, but there is no known specific antidote against it. Of the possible problems related to paraquat intoxication, oliguric acute renal failure, which has been known to develop within 24 or 48 hours after intoxication, are notoriously life-threatening. So we attempted to investigate the clinical characteristics and progress of paraquat-induced acute renal failure and the therapeutic possibilities of herbal medicines. All of the fifteen subjects were treated with intravenous fluid injection of 5% dextrose saline or 10% dextrose water in conjunction with herbal medicines which were used for oral administration or gargling. Gamdutang, a decoction of Semen Glycin(黑豆 200g) and Radix Glycyrrhizae(甘草 100g) with addition of other herbs when necessary, was administered orally. At the same time, gargling fluid, consisted of Chinese ink(墨汁), char-frying powder of Rhei Rhizoma(大黃炒炭末), Succus phyllostachyos(竹瀝), was used to detoxify the oral cavity. Serum levels of Blood Urea Nitrogen(BUN) and Creatinine reached its peak on the third day of hospitalization, but then decreased and fell within the normal range on the 7th day and remained there. Serum levels of Na+ and K+ decreased down below the lower limits of normal range on the 7th day and on the 3rd day, respectively. Then they returned back within normal limits. Mean urine output on the 1st day of hospitalization was 1,050ml and it continuously increased to reach more than 2,000ml on the 14th day. From that day on, it stayed over 2,000ml. Fifteen cases of acute renal failure caused by paraquat intoxication were treated with combined treatments of oriental and western medicine in our hospital. However, we think that it is necessary to study further about the way to combine oriental and western medicine, to find out a more effective treatment method.
