연구배경: 우리나라에서 대체-보완의료가 기관지천식의 환자에서 광범위하게 사용되어지리라고 추측되고 있다. 그러나 우리나라 성인천식환자에서의 대체-보완의료의 실태는 아직 보고된 바가 없다. 이 연구는 우리나라의 성인천식환자에 있어서 대체-보완의료의 사용실태와 경향을 알아보고자 시행하였다.방 법: 2000년 1월부터 2003년 12월까지 경희대병원에 1회 이상 입원한 병력이 있는 천식 환자를 대상으로 하였으며 설문조사 연구에 동의하는 환자 100명에게 직접면담 하거나 전화를 통해 설문조사를 시행했다. 환자들의 병력은 병록지를 참고로 조사하였다.결 과: 조사환자 100명 중 53명이 대체-보완 의료를 경험하였다. 환자가 치료받은 병원 수가 많을수록 대체-보완의료를 경험한 횟수가 많았으며, 연령 별로는 50대가 가장 많이 대체-보완의료를 경험하였다. 흔히 사용한 대체-보완의료의 종류는 음식 및 건강식품이 35명으로 가장 많았다. 그 다음으로 약초가 28명, 침 요법이 9명, 쑥뜸요법이 6명, 그리고 호흡운동이 1명이었다.
Background: There has no known epidemiologic survey on the frequency of complementary-alternative medicine (CAM) use in the treatment of adult asthma in Korea. This study examined the current use of CAM by asthma patients in Korea. Methods: One hundred adults with asthma, who had been admitted to Kyunghee university hospital between January 2000 and December 2003, were enrolled in this survey. They received a structured questionnaire interview and a clinical assessment of prevalence and pattern of CAM use. Results: 53% patients had an experience of at least one type of CAM during their asthma management. Users of CAM had more hospital visits than those who had never used CAM(1.46±0.68 vs. 2.11±1.20, p=0.001). Those in their 50th decades had more experience of CAM (80%) than the other age groups. The methods of CAM used by our patients are as follows: Diet/nutritional therapy in 35 patients(69%), herbal therapy in 28 patients(53%), acupuncture in 9 patients(17%), moxa treatment in 6 patients(11%), breathing exercises in 1 patient(2%). Conclusions: More than 50% of patients with bronchial asthma have used CAM. A more detailed and large scaled study will be needed to define the actual status of the use of CAM in the treatment for asthma. Inaddition, further research on the scientific validation of the clinical efficacy of CAM in asthma management should be followed. (Tuberc Respir Dis 2006; 61: 339-346)
배 경: 지속적인 노력에도 지역사회폐렴에 의한 사망률은 증가하고 있으며 서구에서는 이에 대한 적절한 접근 및 예후 평가를 위해 예후 인자들을 확인하려 하였고 종합적인 접근을 위해 Pneumonia Severity Index(PSI) 등의 지표를 개발하였다. 하지만 국내에서는 단순 지표들만을 이용한 연구에 그치고 있어 PSI를 이용하여 폐렴으로 입원한 환자의 예후에 종합적인 접근을 할 수 있는지 확인하고자 하였다.방 법: 2002년 1월부터 2005년 1월까지 지역사회폐렴으로 입원한 179명의 환자들을 대상으로 생존군/사망군 그리고 일반병실 입원환자/중환자실 입원 환자 사이를 비교하였으며, 각 군에 대해 Pneumonia Severity Index를 분석하였다.결 과: 사망군과 생존군 사이에는 평균 수축기 혈압, 평균 이완기 혈압, 평균 맥박수, 평균 호흡수, 평균 체온, albumin, LDH, total cholesterol, HDL, PT, aPTT, hemoglobin, blood urea nitrogen(BUN)에서 유의한 차이가 있었다. (p<0.05)일반병실과 중환자실 입원환자 사이에는 평균 맥박수, pH, pCO2, pO2, SaO2, 혈청 총 단백질, 알부민, 혈청 총 칼슘, LDH, 총 콜레스테롤, HDL, PT, aPTT, hemoglobin, blood urea nitrogen(BUN)에서 유의한 차이가 있었다. (p<0.05)Pneumonia Severity Index의 경우 class Ⅰ에서 사망률이 가장 낮고 class가 증가할수록 사망률이 증가하였으며 class Ⅴ에서 사망률이 가장 높았다.
Background: Pneumonia is the most common cause of death among infectious diseases with community-acquired pneumonia being the sixth leading cause of death in the USA. In Korea, several studies have evaluated the prognosis of community-acquired pneumonia with a limited number of patients and risk factors. This study, evaluated all the possible risk factors (including the pneumonia severity index; PSI) in for the community-acquired pneumonia patients admitted to a referral hospital. Methods: The medical records of patients admitted to the Chung-Aug University Yongsan Hospital between January 2002 and January 2005 for community-acquired pneumonia were reviewed retrospectively. The demographic data, comorbidity, radiographic findings and laboratory results which might influence the prognosis of pneumonia were analyzed. Results: Among 179 patients admitted for community-acquired pneumonia, 29 patients died (mortality 16%). The risk factors for mortality in the comorbidity category were congestive heart failure and a myocardial infarction. The laboratory data, showed that albumin, LDH, total cholesterol, HDL, PT, aPTT, hemoglobin and blood urea nitrogen (BUN) were related to the prognosis. For the pneumonia severity index, the mortality rate increased in a step-wise manner from class I through class V. Conclusions: Comorbidities such as congestive heart failure and myocardial infarction as well as the albumin, LDH, total cholesterol, HDL cholestreol, prothrombin time, activated partial thrombotin time, hemoglobin and blood urea nitrogen(BUN) are important risk factors for mortality in patients with community-acquired pneumonia. PSI is a valuable index for evaluating the prognosis of community-acquired pneumonia. (Tuberc Respir Dis 2006; 61: 347-355)
연구배경: 패혈증에서 혈중 스테로이드 농도는 유의한 예후인자로서 알려져 있다. 또한 최근에는 이러한 스테로이드의 절대적 및 상대적 결핍 현상이 알려지고 있으며, 이는 스테로이드 보충 치료의 지표로도 이용되고 있다. 본 연구에서는 패혈증 환자에서 혈중 스테로이드 농도, 24시간 뇨 스테로이드 양 및 상대적 부신결핍의 임상적 의의와 기타 패혈증의 혈중 지표와의 연관성에 대하여 알아보고자 하였다. 방 법: 패혈증 환자 26예를 대상으로 초기 혈중 스테로이드와 ACTH, ADH, lactate 등의 농도를 측정하고 24시간 뇨 유리 코티졸 양을 측정하였으며, rapid ACTH stimulation test를 시행하였다.결 과: 패혈증 환자들에서 사망군은 생존군에 비해 기저 무작위 혈청 코티졸 농도가 유의하게 증가되어 있었다. 중증패혈증 환자들에서 24시간 뇨 유리 코티졸은 경증패혈증 환자군에 비해 유의하게 증가되어 있었다. 혈청 코티졸 농도는 ADH, lactate농도와 유의한 상관관계를 나타내었고, 24시간 뇨 유리 코티졸은 혈청 코티졸, lactate 농도와 유의한 상관관계를 보였다. 상대적 부신결핍의 정도는 혈청 코티졸, ADH, lactate 농도와 상관성이 있었다.
Background: Corticosteroids are known to be significant prognostic parameters in sepsis. Recently, an absolute and relative insufficiency of the corticosteroids system has often been reported to often develop particularly in severe sepsis. Degree of such an adrenal insufficiency not only has prognostic implications but also can be used to guide corticosteroids replacement therapy. The 24-hour urinary cortisol levels as well as serum cortisol concentrations were measured to assess the clinical significance and their relationship with the other parameters of sepsis, and also evaluated the clinical implications of the relative adrenal insufficiency. Methods: 26 consecutive patients with sepsis were enrolled. The basal random serum cortisol, ACTH, ADH, lactate levels and 24-hour urinary free cortisol amount were measured. The rapid ACTH (250 μg) stimulation test was also performed. Results: Basal serum cortisol levels were higher in the non-survivors than in the survivors. The 24-hour urinary free cortisol levels were higher in the patients with severe sepsis than in those without. The serum cortisol levels strongly correlated with the serum ADH and lactate levels. The 24-hour urinary free cortisol levels strongly correlated with the serum cortisol and lactate levels. The fractional changes in the cortisol levels after the rapid ACTH stimulation tests correlated with the serum cortisol, ADH, and lactate levels. Conclusion: Both the serum cortisol and 24-hour urinary cortisol were found to be significant prognostic factors in sepsis, and showed a strong correlation with the other parameters. The relative adrenal insufficiency might also be an important clinical parameter. (Tuberc Respir Dis 2006; 61: 356-365)
연구배경 : Paraquat는 P-450 reductase에 의해 반응성 산소유리기(ROS)를 발생시켜 세포막, 단백질, 핵산 등과 반응함으로써 세포손상을 유도하며 급성 폐 손상을 일으킨다. 최근 급성 폐 손상 및 급성 호흡곤란 증후군에 있어서 폐상피세포의 아포프토시스가 중요한 역할을 한다고 알려지기 시작하였다. 이에 반응성 산소유리기에 의한 폐 손상의 대표적 물질인 paraquat로 인한 폐상피세포의 세포죽음이 아포프토시스인지 확인하고 dexamethasone, N-acetylcysteine, 그리고 bcl-2가 paraquat로 인한 폐상피 세포죽음에 어떠한 영향을 미치는지 등을 연구하였다.방법 : 폐상피세포주인 A549와 BEAS-2B 세포주, 그리고 bcl-2 construct를 유전자 주입한 A549 pcDNA3-bcl-2 세포주를 이용하였다. 아포프토시스는 Annexin Ⅴ assay를 이용하여서 판정하였으며 세포독성 검사는 MTT assay를 이용하였다. Paraquat는 0, 1 μM, 10 μM, 100 μM, 1 mM, 10 mM의 농도로 사용하였다. Dexamethasone은 1 μM의 농도로 paraquat 투여 12시간 전에 전처치하였고, N-acetylcysteine은 1 mM의 농도로 paraquat 투여 1시간 전에 전처치하였다.결과 : 양 세포주 모두에서 paraquat는 농도와 시간 경과에 따라서 세포죽음을 증가시켰고, 이러한 세포죽음은 아포프토시스였다. N-acetylcysteine과 dexamethasone은 시간과 농도에 따라 약간의 차이가 있으나 전반적으로 10~30%의 방어효과가 있었다. Bcl-2를 과발현시킨 A549-bcl-2 세포주에서 A549-neo 세포주에 비해 paraquat에 의한 세포독성이 약 20~30% 정도 차단되었다.
Background: Paraquat is extremely toxic chemical material, which generates reactive oxygen species (ROS), causing multiple organ failure. In particular, paraquat leads to irreversible progressive pulmonary fibrosis. Exaggerated cell deaths exceeding the normal repair of type Ⅱ pneumocytes leads to mesenchymal cells proliferation and fibrosis. This study examined the followings; ⅰ) whether or not paraquat induces cell death in lung epithelial cells; ⅱ) whether or not paraquat-induced cell deaths are apoptosis or necrosis; and ⅲ) the effects of N-acetylcysteine, dexamethasone, and bcl-2 on paraquat-induced cell deaths. Methods: A549 and BEAS-2B lung epithelial cell lines were used. The cell viability and apoptosis were evalluated using a MTT assay, Annexin Ⅴ staining was monitored by fluorescence microscopy, The level of bcl-2 inhibition was examined by establishing stable A549 pcDNA3-bcl-2 cell lines throung the transfection of pcDNA3-bcl-2 with the mock. Results: Paraquat decreased the cell viability in A549 and BEAS-2B cells in a dose and time dependent manner. The Annexin Ⅴ assay showed that apoptosis was the type of paraquat-induced cell death. Paraquat-induced cell deaths was significantly inhibited by N-acetylcysteine, dexamethasone, and bcl-2 overexpression. The cell viability of A549 cells treated with N-acetylcysteine, and dexamethasone on the paraquat-induced cell deaths were increased significantly by 10 ~ 20%, particularly at high doses. In addition, the cell viability of A549 pcDNA3-bcl-2 cells overexpressing bcl-2 was significantly higher than the untransfected A549 cells. Conclusion: Paraquat induces apoptotic cell deaths in lung epithelial cells in a dose and time dependent manner. The paraquat-induced apoptosis of lung epithelial cells might occur through the mitochondrial pathway. (Tuberc Respir Dis 2006; 61: 366-373)

A 29-year-old male patient was admitted due to his general weakness and poor oral intake for several months. He was diagnosed as having Crohn disease 16 years ago and total colectomy was performed 10 years ago. On the 3rd day after admission, gross hematuria and sudden hemoptysis combined with diffuse infiltration were noted on chest X-ray. His symptoms and the diffusely increased lung opacities improved with administering high-dose steroid therapy. Later, anti-GBM antibody was found to be positive on the laboratory findings. We report here on a rare case of Goodpsture syndrome combined with prolonged Crohn disease along with a review of literature. (Tuberc Respir Dis 2006; 61: 384-388)

Tsutstugamushi disease is a major febrile disease that generally occurs in the fall in Korea with hemorrhagic fever with renal syndrome and leptospirosis. This disease is often accompanied by interstitial pneumonia, acute renal failure and liver failure. The causative agent, namely Orientia tsutsugamushi, is transmitted to humans through the bite of a laval trombiculid mite, which is commonly known as a chigger. A 78 year old man was admitted in October 2004 with intractable fever and a drowsy mentality. Two weeks earlier, he visited a private clinic complaining of a simple skin rash. He was treated with antihistamine and steroid, but his symptoms were aggravated and he was referred to our hospital. His physical examination and laboratory findings showed a septic shock status. The maculopapular rash had spread over his face, chest, abdomen and extremities. Eschar was observed in lower back area but it was too difficult to distinguish it from other skin rashes. His chest X-ray appeared as diffuse nodular patchy consolidations in the bilateral lung parenchyme. He was treated with a mechanical ventilator and doxycycline under th suspicion of Tsutstugamushi disease. However, he suffered multiorgan failure accompanied by acute respiratory distress syndrome, acute renal failure and acute hepatitis. He was treated in the intensive care unit for approximately 12 weeks and his general condition was recovered. (Tuberc Respir Dis 2006; 61: 389-393)

Periodic hemoptysis occurring at the time of menstruation (catamenial hemoptysis) is a rare disorder and generally signifies indicates the presence of thoracic endometriosis. A diagnosis of catamenial hemoptysis is usually established based on the clinical history and the exlusion of other causes of the recurrent hemoptysis. Serial computed tomograms of the chest during and in the interval between menstruations periods is a useful confirmatory test. We report the case of a 22 year-old women who suffered from catamenial hemoptysis for 10 months and was treated successfully with a wedge resection of the lesion by video-assisted thoracoscopic surgery(VATS). There was no evidence of recurrence. In conclusion. VATS is a good choice as a for single focus for catamenial hemoptysis. (Tuberc Respir Dis 2006; 61: 394-397)

Trousseau's syndrome comsists of migratory thrombophlebitis and thromboembolic disorders of the venous and arterial systems in a malignancy or occult cancer. The overall incidence has been reported to vary from 1 to 11%. Pancreatic, lung, prostate, and stomach cancer is associated with the greatest risk of thromboembolic events. We encountered a 49-year-old man who presented with painful swelling of his lower legs. The chest radiograph showed increased opacity of the Left middle lung fields and Doppler sonography showed a thrombus in the left superficial femoral vein. Chest Computed Tomography showed a 5cm sized left hilar mass invading the pericardium with lymphadenopathy. The bronchoscope biopsy demonstrated an adenocarcinoma of the lung. Platinum based chemotherapy and anticoagulant therapy with warfarin was carried out. The patient was later discharged with an improvement in the painful swelling of his lower legs.
