Purpose: In this study, symptom experience and quality of life(QoL) in patients with Bronchial asthma(BA) and Bronchiectasis(BRC) were examined to develop nursing strategies. Method: Data collection was done with 61 outpatients with BA and 43 outpatients with BRC in January and February, 2001. Data analyses were performed using SPSS Win 8.0. Result: The mean scores of symptom experience were 11.3 and 10.8 in patients with BA and BRC, respectively. The mean score of QoL was 18.0 in patients with BA and 19.2 in patients with BRC. There were statistically significant differences in the score of the symptom experience according to sex and occupation in patients with BA, and to the religion and occupation in patients with BRC. The mean score of QoL had significant difference according to the income in patients with BA, but had no significant differences in patients with BRC. The score of QoL had significantly correlated with the degree of symptom experience in patients with BA(p=.000) and with BRC(p=.022). Conclusion: The degree of symptom experience negatively correlated with QoL. Therefore, symptoms experienced by patients should be considered in development of nursing strategies for patients with BA and BRC.

To investigate the alteration of airway mucin in airway disease patients, immunoassay procedures were employed using monoclonal antibodies HM02 and HM03 (Hybridoma, 18,457-463, 1999). Alteration of mucin release was determined by ELISA and the integrity of mucin was determined by Western blot. In ELISA, it was found that mucin release increased from pneumonia, chronic cough, bronchiectasis, eosinophilic pneumonia, lung cancer and bronchial asthma patients. In Western blot, the increase in immunoreactivity was observed in case of pneumonia, chronic cough, bronchiectasis and bronchial asthma. In bronchial asthma, there was no obvious degradation of mucin while in other diseases, varying degree of mucin degradation was observed. The data from the present study implicate that HMO2 and HM03 are suitable for the immunological analysis of mucin in airway disease patients. The role of increased mucin release and varying degree of mucin degradation on airway diseases should be further investigated in the future.

Objective: To determine the effects of respiration on the size of lung cysts by comparing inspiratory and expiratory high-resolution CT (HRCT) scans. Materials and Methods: The authors evaluated the size of cystic lesions, as seen on paired inspiratory and expiratory HRCT scans, in 54 patients with Langerhans cell histiocytosis (n = 3), pulmonary lymphangiomyomatosis (n = 4), confluent centrilobular emphysema (n = 9), paraseptal emphysema and bullae (n = 16), cystic bronchiectasis (n = 13), and honeycombing (n = 9). Using paired inspiratory and expiratory HRCT scans obtained at the corresponding anatomic level, a total of 270 cystic lesions were selected simultaneously on the basis of five lesions per lung disease. Changes in lung cyst size observed during respiration were assessed by two radiologists. In a limited number of cases (n = 11), pathologic specimens were obtained by open lung biopsy or lobectomy. Results: All cystic lesions in patients with Langerhans cell histiocytosis, lymphangiomyomatosis, cystic bronchiectasis, honeycombing, and confluent centrilobular emphysema became smaller on expiration, but in two cases of paraseptal emphysema and bullae there was no change. Conclusion: In cases in which expiratory CT scans indicate that cysts have become smaller, cystic lesions may communicate with the airways. To determine whether, for cysts and cystic lesions, this connection does in fact exist, paired inspiratory and expiratory HRCT scans are necessary.

Background: Bronchiectasis (BE) remains a rare respiratory disease in Korea. This retrospective study was done to investigate the potential pathogenic microorganisms (PPMs) that cause in patients with BE, through the use of sputum specimens. Methods: One hundred eleven adult patients, who had undergone chest computed tomography (CT), sputum gram stain/culture, and BE detected by chest CT, were included in this study. Sputum adequacy was determined by using Murray-Washington classification. Results: The mean (${\pm}$SD) age of patients was 60.9 (${\pm}$14.0). The number of PPMs was 167 (67%) in the total 248 isolated organisms. The most frequent PPMs were P. aeruginosa (23.4%), K. pneumoniae (10.5%), and S. aureus (8.4%). The proportion of adequate sputum (AS) was 25.8% in the total sputum specimens. The patients with AS were 41 (37%) and the patients with inadequate sputum (IS) were 70 (63%). The proportion of P. aeruginosa was higher in AS compared to that of IS (44% vs. 19%, p=0.004). The BE score was also higher in P. aeruginosa (+) patients compared to that of P. aeruginosa (-) patients (10.8 vs. 7.6, p=0.001). Conclusion: Although the proportion of AS in the total sputum was low, PPMs were isolated in most patients with BE. It is likely that P. aeruginosa was isolated in AS and AS patients had higher BE scores.

CA 125의 상승은 난소의 악성종양에 나타날 수 있지만 비특이적이다. CA 125의 상승은 다양한 양성 질환 혹은 악성 종양에서 나타날 수 있다. 저자들은 최근 지속적으로 혈중 CA 125 수치가 증가되어 있지만 경질 초음파, 흉부 CT, PET-CT 등에서 악성 종양이 발견되지 않은 기관지확장증 1예를 경험하였다. 14개월의 추적 관찰 기간 중에도 난소암과 같은 악성 종양은 발견되지 않고 기관지확장증에 병발된 폐렴 이외에는 특이 소견이 없어, 혈중 CA 125의 상승은 기관지확장증에 의한 급성 폐 손상에 의한 것으로 추정된다. 혈중 CA 125 수치의 상승은 환자의 임상 양상과 연관하여 조심스럽게 판단하여야 될 것으로 생각된다.

Bronchoarterial (BA) ratio is a commonly used criterion to define airway dilatation despite the lack of normative human and animals. The objective of our study was to compare the range of normal bronchial to accompanying arterial diameter ratio with previous reports on CT scan of the thorax in dogs and assess influence anesthetics on BA ratio in dogs. Dogs undergoing multidetector CT scan of the chest for nonpulmonary conditions at a single center were prospectively identified. High-resolution reconstruction was performed on those included and both airway lumen and vessel diameters were measured in the lobar bronchi of the left cranial (cranial and caudal parts), right cranial, right middle, left caudal, and right caudal lung lobes. Eight dog were included; Mean of the mean BA ratios was $1.43{\pm}0.24$ (95% CI = 1.36 - 1.50) in inhalation anesthetic group. In propofol group, the mean of the mean BA ratios was $1.13{\pm}0.29$ (95% CI = 1.04 - 1.22). In medetomidine group, the mean of the mean BA ratios was $0.89{\pm}0.19$ (95% CI = 0.83 - 0.95). Comparing individual lobes within anesthetic category, there was no signicant difference in mean BA ratio between lung lobes or between dog according to inhalation, propofol, and medetomidine group (P = 0.630, P = 0.878, and P = 0.508, respectively). The BA ratio in these clinically normal dogs was consistent and may be a useful tool in evaluating for bronchiectasis on CT images. However, some different criteria for bronchiectasis were applied by the anesthetic methods.

Background: A tuberculous destroyed lung is sequelae of pulmonary tuberculosis and causes various respiratory symptoms and pulmonary dysfunction. The patients with a tuberculous destroyed lung account for a significant portion of those with chronic lung disease in Korea. However, few reports can be found in the literature. We investigated the computed tomography (CT) findings in a tuberculous destroyed lung and the correlation with lung function. Methods: A retrospective analysis was carried out for 44 patients who were diagnosed with a tuberculous destroyed lung at the Keimyung University Dongsan Hospital between January 2004 and December 2009. Results: A chest CT scan showed various thoracic sequelae of tuberculosis. In lung parenchymal lesions, there were cicatrization atelectasis in 37 cases (84.1%) and emphysema in 13 cases. Bronchiectasis (n=39, 88.6%) was most commonly found in airway lesions. The mean number of destroyed bronchopulmonary segments was 7.7 (range, 4~14). The most common injured segment was the apicoposterior segment of the left upper lobe (n=36, 81.8%). In the pulmonary function test, obstructive ventilatory defects were observed in 31 cases (70.5%), followed by a mixed (n=7) and restrictive ventilatory defect (n=5). The number of destroyed bronchopulmonary segments showed a significant negative correlation with forced vital capacity (FVC), % predicted (r=-0.379, p=0.001) and forced expiratory volume in one second ($FEV_1$), % predicted (r=-0.349, p=0.020). After adjustment for age and smoking status (pack-years), the number of destroyed segments also showed a significant negative correlation with FVC, % predicted (B=-0.070, p=0.014) and $FEV_1$, % predicted (B=-0.050, p=0.022). Conclusion: Tuberculous destroyed lungs commonly showed obstructive ventilatory defects, possibly due to bronchiectasis and emphysema. There was negative correlation between the extent of destruction and lung function.

Background: Fractional exhaled nitric oxide (FeNO) can be measured easily, rapidly, and noninvasively for the assessment of airway inflammation, particularly mediated by eosinophil, such as asthma. In bronchiectasis (BE), the pathogenesis has been known as chronic airway inflammation and infection with abnormal airway dilatation; however, there are little studies to evaluate the role of FeNO in BE. Methods: From March 2010 to February 2012, 47 patients with BE, diagnosed by high resolution computed tomography (HRCT), performed FeNO, compared with asthma and chronic obstructive pulmonary disease (COPD). All patients carried out a complete blood count including eosinophil count, chemistry, sputum examination, and spirometry, if indicated. A retrospective analysis was performed to elucidate the clinical role of FeNO in BE patients. Results: The mean FeNO levels in patients with BE was $18.8{\pm}1.5$ part per billion (ppb), compared to $48.0{\pm}6.4$ and $31.0{\pm}4.3$ in those with asthma and COPD, respectively (p<0.001). The FeNO levels tended to increase along with the disease severity scores by HRCT; however, it was statistically not significant. FeNO in BE with a co-infection of nontuberculous mycobacteria was the lowest at $17.0{\pm}3.5$ ppb among the study population. Conclusion: FeNO in BE was lower than other chronic inflammatory airway diseases, particularly compared with asthma. For clinical application of FeNO in BE, more large-scaled, prospective studies should be considered.

A case of pulmonary aspergillosis, strongly suspected before operation and confirmed after surgical intervention, was reviewed with related literatures. It has become to be a well recognized fact that pulmonary mycosis generally results from sapro-phytic colonization of previous lung cavities usually due to pulmonary tbc, lung abscess, cyst of bronchiectasis. Recently, the author experienced one case of pulmonary aspergillosis which had been diagnosed and treated as tuberculosis for 6 years. Sputum culture, immunologic study and X-ray findings constitute essential part of diagnosis. Surgical resection is the treatment of choice combined with systemic administration of anti-fungal agents to eradicate the disease completely.
