연구배경: 만성폐질환 환자에서 삶의 질을 측정하는 도구로서 세인트조지 호흡기 설문(St George`s Respiratory Questionnaire;SGRQ)이 개발되어 치료효과를 판정하는 측정지표로 널리 사용되고 있으나 영어권국가에서 만들어 졌기 때문에 우리나라에서 동일하게 사용하는데 제한점을 가지고 있다. 따라서 이의 정확한 적용을 위해서 언어, 기술, 개념적인 관점을 고려하여 한국어 설문지를 만들고 이들의 타당도와 신뢰도를 평가하였다. 방법: 한국판 세인트조지 호흡기 설문은 번역, 역번역, 전문가 패널의 수정을 통해 완성되었고, 세브란스병원 호흡기내과를 방문한 환자를 대상으로 하여 이 설문을 시행하였다. 신뢰도 검정은 Cronbach`s α를 구하여 측정하였고 타당도는 폐기능검사, 6분보행검사, 호흡곤란지수와 산소포화도 검사를 동시에 시행하여 설문 검사결과와의 상관관계를 알아보았다. 결과: 74명의 환자를 대상으로 시행하였으며, 남녀 비는 2.2:1, 평균연령은 63.8±10.3세였다. 이 중 천식환자는 27명(36.5%), 만성폐쇄성폐질환 환자는 39명 (52.7%)이었고, 결핵에 의한 파괴 폐환자는 8명(10.8%)이었다. Cronbach`s α 값은 증상영역, 활동영역, 영향영역 및 총 점수에서 각각 0.63, 0.87, 0.89, 0.92 이였다. 총점수와 FEV1, FVC, 6분보행거리, 산소포화도, 호흡곤란지수와 유의한 상관관계를 보였다. 결론: 한국어판 세인트조지 호흡기 설문은 만성폐질환 및 천식과 같은 만성폐질환 환자에서 신뢰도가 높았고 총점수와의 상관관계는 6분보행검사 및 산소포화도에서 높음을 알수 있었고 폐기능 검사와의 상관계수는 원저인 세인트조지 호흡기설문 및 타 국가의 번역본 호흡기설문에서와 같이 높지 않음을 알 수 있었다. 따라서 우리나라에서도 호흡기질환의 삶의 질에 대한 치료효과 판정에 활용할 수 있을 것으로 기대된다. Background: The health-related quality of life (HRQL) for patients with chronic respiratory disease has been emphasized, because chronic respiratory disease (CRD) is chronic and progressive, and it finally causes disability. HRQL instruments may be useful for monitoring patients` progress or for determining the most appropriate choice of treatment. We describe the adapting St George`s Respiratory Questionnaire (SGRQ), which is a self-administered questionnaire developed by Jones et al. (1991), into the Korean version for covering three domains of health for the patients suffering with airways disease. Method: We obtained the original SGRQ from the author after gaining permission. For adaptation, we created an expert panel and translated the original questionnaire into Korean language. The translated questionnaire was then back-translated by bilingual experts and we compared it with the original questionnaire. After correction and feasibility testing, 74 patients with chronic respiratory disease (COPD, asthma, destroyed lung) completed the Korean version of the SGRQ. The clinical status of each patients was evaluated concurrently with measurement of their health status. Result: The Korean version of the SGRQ was acceptable and easy to understand. Cronbach`s alpha reliability coefficient was 0.92 for the overall scale and 0.63 for the Symptoms, subscale, 0.87 for the Activity, subscale, and 0.89 for the Impacts subscales. The correlation coefficients between the overall score and the Borg scale score, oxygen saturation, and forced expiratory volume in one second (FEV1) were 0.52, -0.32 and -0.26, respectively. These results support that the Korean SGRQ was correlated with other measurements. Conclusion: The Korean SGRQ was reliable and valid for patients with chronic respiratory disease, such as COPD, asthma, and destroyed lung. The SGRQ score was well correlated with other respiratory measurements as well. Although further studies should complete the adaptation work, our results suggest that the SGRQ may be used in Korea and also for international studies involving Korean CRD patients.

Background: Adaptive support ventilation (ASV), an automated closed-loop ventilation mode, adapts to the mechanical characteristics of the respiratory system by continuous measurement and adjustment of the respiratory parameters. The adequacy of ASV was evaluated in the patients with acute lung injury (ALI). Methods: A total of 36 patients (19 normal lungs and 17 ALIs) were enrolled. The patients` breathing patterns and respiratory mechanics parameters were recorded under the passive ventilation using the ASV mode. Results: The ALI patients showed lower tidal volumes and higher respiratory rates (RR) compared to patients with normal lungs (7.1±0.9 mL/kg vs. 8.6±1.3 mL/kg IBW; 19.7±4.8 b/min vs. 14.6±4.6 b/min; p<0.05, respectively). The expiratory time constant (RCe) was lower in ALI patients than in those with normal lungs, and the expiratory time/RCe was maintained above 3 in both groups. In all patients, RR was correlated with RCe and peak inspiratory flow (rs=-0.40; rs=0.43; p<0.05, respectively). In ALI patients, significant correlations were found between RR and RCe (rs=-0.76, p<0.01), peak inspiratory flow and RR (rs=-0.53, p<0.05), and RCe and peak inspiratory flow (rs=-0.53, p<0.05). Conclusion: ASV was found to operate adequately according to the respiratory mechanical characteristics in the ALI patients. Discrepancies with the ARDS Network recommendations, such as a somewhat higher tidal volume, have yet to be addressed in further studies.

연구배경: 흡연은 많은 질병과 사망의 가장 중요한 원인이나 니코틴의존성으로 인해 금연이 어렵고 이로 인한 사회적, 의료적 손실이 증가함에도 불구하고 개선되지 못하고 있다. 이러한 니코틴의존성 중 물리적 의존성과 독립적으로 관여할 것으로 생각되는 사회, 문화적 니코틴의존성을 알아보고자 연구하였다. 방법: 2006년 5월부터 8월까지 일개 대학병원 직원과 일개 의과대학생, 일반 대학생 및 건강 검진자들을 대상으로 KTSND-K 설문지를 이용하여 흡연에 관한 의식 조사를 시행하였다. 결과: 총 741명 중 평균 연령은 31.8±11.6세이었고, 남자는 428명(57.8%)이었다. 흡연력은 현재흡연자 102명(13.8%), 과거흡연자 95명(12.8%), 비흡연자 544명(73.4%)이었다. 흡연력에 따른 KTSND-K 총점은 현재흡연자, 과거흡연자, 비흡연자에서 각각 17.1±5.4, 14.3±5.5, 12.3±5.5로 흡연자일수록 의미 있게 높게 나타났다(p<0.001). 성별에 따른 총점의 차이는 남녀 각각 14.3±5.7, 11.7±5.4로 남성에서 유의하게 높았다(p<0.001). 그러나 현재흡연자 중 흡연 행태 및 금연 의지에 따라 각 군을 나누어 비교하였을 때 각 군간의 KTSND 총점의 차이는 보이지 않았다. 비흡연자 중 62.5%에서 간접 흡연의 피해를 느꼈으며, 간접 흡연을 경험하는 주요 장소는 주점 56.8%, 식당 32.3%, 학교 30.2%, 노래방 22.8%, 길거리 18.6% 등 공공 장소가 많았다. 결론: KTSND-K 설문지는 한국 흡연자의 니코틴의존성 중 사회적 니코틴의존성을 평가할 수 있는 유용한 방법이 될 수 있다고 생각된다. Background: Smoking is one of the most important leading causes of morbidity and mortality. Smoking habit is recognized as nicotine dependence, which consists of physical and psychosocial dependence. To evaluate social nicotine dependence, the Kano Test for Social Nicotine Dependence (KTSND) working group developed a new questionnaire, which consists of 10 questions with a total score of 30 in Japan. We examined the social nicotine dependence among healthy adults using the new KTSND questionnaire and evaluated validity of the KTSND questionnaire in Korea. Method: We applied Korean KTSND questionnaire version 2 to employees of hospital, university students and people for medical examination and promotion test. Complete data obtained from the 741 responders were analyzed. Result: The mean age of responders was 31.8 years. Among them, males were 57.8%. Current smokers, ex-smokers, and non-smokers were 13.8%, 12.8%, and 73.4% respectively. According to smoking status, the total KTSND scores of current smokers were significantly higher than those of ex-smokers, and of non-smokers (17.1±5.4 versus 14.3±5.5, and 12.3±5.5, p≤0.001). The total KTSND scores of males were higher than those of females, suggesting that males have a propensity for depending nicotine socially much more than females (14.3±5.7 and 11.7±5.4 respectively, p<0.001). Eight of ten questions produced significantly different scores among three different smoking groups. When current smokers were sub-classified by heavy smoking index (HSI) that represented physical nicotine dependence, we did not find a significant difference of KTSND score between low HSI group (<4) and high HSI group (≥4), This finding suggested that the psychosocial dependence might play a different role from physical nicotine dependence in smoking. Most of the non-smokers (62.5%) had an experience of harmful passive smoking especially in public place. Conclusion: Our study suggested that the KTSND questionnaire could be a useful method to evaluate psychosocial aspects of smoking. (Tuberc Respir Dis 2007; 62: 365-373)

Angiosarcoma is a rare but highly malignant tumorthat usually arises in the scalp or face of elderly males. Distant metastases favor the lung, liver, lymph nodes and skin. Metastatic pulmonary angiosarcoma commonly takes the form of a nodule but can sometimes appear as a thin-walled cyst. We report a case of 65 years-old male with a spontaneous pneumothorax, who underwent excision and radiotherapy for an angiosarcoma of the scalp 2 years ago. A chest CT scan revealed multiple cysts in the lung. The video-assisted thoracoscopic lung biopsy demonstrated subpleural cysts without tumor cells. A skin biopsy of the scalp showed an angiosarcoma. This case was diagnosed as a recurrence of an angiosarcoma with a supposed lung metastasis. This case suggests that a spontaneous pneumothorax in elderly people may be secondary to a pulmonary metastasis from an angiosarcoma of the scalp. (Tuberc Respir Dis 2008;64:374-378)
