BACKGROUND: The possibility of developing pulmonary tuberculosis usually increases with increasing age. Therefore, the incidence of endobronchial tuberculosis in older people may increase. We evaluated the clinical characteristics in patients with endobronchial tuberculosis above the age of 70 years. METHODS: We enrolled 74 patients (12 males and 62 females; mean age 64.6+/-16.2 years) that were diagnosed with endobronchial tuberculosis from March 2003 to July 2006 at Gyeongsang University Hospital. We retrospectively evaluated the clinical characteristics of endobronchial tuberculosis for patients 70 years or older (older group) and for patients below the age of 70 years (younger group). RESULTS: The number of patients in the older group was 41 (55%). Cough was the most common symptom in the two groups of patients and dyspnea on exertion was more common in the older group of patients than in the younger group of patients (31.7% vs. 12.1%). The actively caesating type of disease was more common in the younger group of patients than in the older group of patients (66.7% vs. 39%). The edematous type of disease was more common in the older group of patients than in the younger group of patients (53.7% vs. 27.2%) (p<0.05). Tracheal and main bronchial involvement of lesions were more common for the younger group of patients than for the older group of patients (30.3% vs. 9.7%) (p<0.05). CONCLUSION: Endobronchial tuberculosis was commonly observed in patients older than 70 years and this group of patients had some clinical characteristics that were different from the younger group of patients.

BACKGROUND: Right middle lobe syndrome (RMLS) is defined as transient or chronic and recurrent atelectasis of the right middle lobe. Although numerous conditions are associated with RMLS, there are very few recent reports in Korea. This study evaluated the causes of RMLS in a local tertiary hospitalover a period of 42 months. METHOD: Eighty-eight patients (M:F=64:22, mean age: 67.2+/-10.3 years), who had consistent chest radiography findings and underwent bronchoscopy in Gyeongsang University Hospital from January 2003 to July 2006, were enrolled in this study. The clinical characteristics and causes of RMLS in these patients were retrospectively reviewed. RESULTS: The most common symptoms fo RMLS were cough, dyspnea and sputum. Tuberculosis was the most common cause (endobronchial tuberculosis in 22 and pulmonary tuberculosis in 1) The other causes were bronchial stenosis by benign fibrotic changes in 22 cases (25%), anthracofibrosis in 13 cases (14.8%), pneumonia in 11 cases (12.5%), lung cancer in 10 cases (11.4%), mucus impaction in 3 cases (3.4%), bronchiectasis in 2 cases (2.3%) and no demonstrable causes in 7 cases (8%). The bronchoscopy findings were mucosal edema with hyperemic changes in 38 cases (43.2%), mucosal edema with anthracotic pigmentation in 16 cases (18.2%), mucus impaction in 13 cases (14.8%), fibrotic stenosis in 13 cases (14.8%), a mass like lesion in 8 cases (9.1%), exudative necrotic material in 4 cases (4.5%), narrowing as a result of extrinsic compression in 2 cases (2.3%) and no demonstrable abnormalities in 12 cases (13.6%). CONCLUSION: Right middle lobe syndrome was observed more frequently in patients over the age of 65. The causes were mainly benign diseases with endobronchial tuberculosis being the most common.

A 70-year-old man was referred to the department of pulmonology due to blood tinged sputum and an abnormal chest X-ray. The chest X-ray and CT scans revealed a lobulated contour mass-like lesion in the left upper lung field. The bronchoscopic examination showed a whitish and polypoid mass occluding the left upper lobe bronchus. A biopsy specimen from the lesion revealed many aspergillus hyphae. Intravenous and oral itraconozole were administered over a 4 weeks period. Several months later, the size of the mass on chest X-ray increased and a percutaneous lung biopsy revealed a sarcomatoid carcinoma. We reported a case of lung cancer that was obscured by an endobronchial aspergilloma with a review of the relevant literature.

Mycobacterium avium complex (MAC) infection is a common opportunistic infection in patients with AIDS (acquired immune deficiency syndrome). Pulmonary involvement of MAC may range from asymptomatic colonization of the respiratory tract to invasive parenchymal or cavitary disease. However, endobronchial lesions with MAC infection are rare in immunocompetent and immunosuppressed hosts. Here, we report MAC infection presenting as an endobronchial mass in a patient with AIDS.

PURPOSE: Endobronchial tuberculosis (EBTB) presenting as right middle lobe syndrome (RMLS) is an uncommon clinical condition. We investigated the clinical characteristics in patients with EBTB presenting as RMLS. PATIENTS and METHODS: We retrospectively reviewed the records of 22 patients with EBTB presenting as RMLS who were diagnosed at our hospital from 2003 to 2006. RESULTS: Its occurrence was more common in females than males (F, 18; M, 4). The mean age was 70.3 +/- 8.5 years, and 17 patients were above the age of 65 years. Cough with sputum was the most common manifestation and 2 patients were asymptomatic. In bronchoscopic analysis, the most common finding was edematous-type EBTB, which was found in 15 patients, followed by actively caseating type in 6 and tumorous type in 1. Acid-fast bacilli (AFB) staining for bronchial washing fluid was positive in only 5 patients: 1 with edematous type and 4 with actively caseating type. Bronchoscopic biopsy showed chronic granulomatous inflammation in 16 patients. Follow-up chest X-ray after treatment showed complete disappearance of the lesion in 2 patients, more than 50% improvement in 5, less than 50% improvement in 5, and no change of lesion in 4. CONCLUSION: Edematous-type EBTB was the most common type of EBTB presenting as RMLS, and it usually occurred in elderly patients. Culturing for mycobacterium and histologic examination by bronchoscopy are necessary for proper diagnosis in these patients.

PURPOSE: A retrospective investigation of the clinical and radiologic features as well as the bronchoscopic appearance was carried out in patients with endobronchial aspergilloma. MATERIALS AND METHODS: Ten patients with endobronchial aspergilloma diagnosed by bronchoscopy and histological examination were identified at the Gyeongsang University Hospital of Korea, from May 2003 to May 2009. RESULTS: The patients included 9 men and 1 woman, and the age of the patients ranged from 36 to 76 (median, 58 years). The associated diseases or conditions were: previous pulmonary tuberculosis in 7 patients, lung cancer in 2 patients, pulmonary resection in 1 patient, and foreign body of the bronchus in 1 patient. The chest radiologic finding showed fibrotic changes as a consequence of previous tuberculosis infection in 6 patients and a mass-like lesion in 2 patients. Two patients had a co-existing fungus ball, and an endobronchial lesion was suspected in only 2 patients on the CT scan. The bronchoscopic appearance was a whitish to yellow necrotic mass causing bronchial obstruction in 7 patients, foreign body with adjacent granulation tissue and whitish necrotic tissue in 1 patient, whitish necrotic tissue at an anastomosis site in 1 patient, and a protruding mass with whitish necrotic tissue in 1 patient. CONCLUSION: An endobronchial aspergilloma is a rare presentation of pulmonary aspergilosis and is usually incidentally found in immunocompetent patients with underlying lung disease. It usually appears as a necrotic mass causing bronchial obstruction on bronchoscopy and can be confirmed by biopsy.

BACKGROUND: Acute respiratory failure can occur paradoxically on initiation of anti-tuberculosis (TB) treatment in patients with pulmonary TB. This study is aimed to analyze the clinical features of anti-TB treatment induced acute respiratory failure. METHODS: We reviewed the clinical and radiological characteristics of 8 patients with pulmonary tuberculosis (5 men and 3 women; mean age, 55 +/- 15.5 years) who developed acute respiratory failure following initiation of anti-TB medication and thus required mechanical ventilation (MV) in the intensive care unit (ICU). RESULTS: The interval between initiation of anti-TB medication and development of MV-requiring acute respiratory failure was 2-14 days (mean, 4.4 +/- 4.39 days), and the duration of MV was 1-18 days (mean, 7.1 +/- 7.03 days). At admission, body temperature and serum levels of lactate dehydrogenase and C-reactive protein were increased. Serum levels of protein, albumin and creatinine were 5.8 +/- 0.98, 2.3 +/- 0.5 and 1.8 +/- 2.58 mg/ml, respectively. Radiographs characterized both lung involvements in all patients. Consolidation with the associated nodule was noted in 7 patients, ground glass opacity in 2, and cavitary lesion in 4. Micronodular lesion in the lungs, suggesting miliary tuberculosis lesion, was noted in 1 patient. At ICU admissions, the ranges of the APACHE II and SOFA scores were 17-38 (mean, 28.2 +/- 7.26) and 6-14 (mean, 10.1 +/- 2.74). The mean lung injury score was 2.8 +/- 0.5. Overall, 6 patients died owing to septic shock and multiorgan failure. CONCLUSIONS: On initiation of treatment for pulmonary TB, acute respiratory failure can paradoxically occur in patients with extensive lung parenchymal involvement and high mortality.

BACKGROUND: Pneumothorax (PTX) can occur as a complication of positive pressure ventilation in mechanically ventilated patients. METHODS: We retrospectively reviewed the clinical characteristics of patients who developed PTX during mechanical ventilation (MV) in the intensive care unit (ICU). RESULTS: Of the 326 patients admitted (208 men and 118 women; mean age, 65.3 +/- 8.74 years), 15 (4.7%) developed PTX, which was MV-associated in 11 (3.3%) cases (6 men and 5 women; mean age, 68.3 +/- 9.12 years) and procedure-associated in 4. Among the patients with MV-associated PTX, the underlying lung diseases were acute respiratory distress syndrome in 7 patients, interstitial lung disease in 2 patients, and chronic obstructive pulmonary disease in 2 patients. PTX diagnosis was achieved by chest radiography alone in 9 patients and chest computed tomography alone in 2 patients. Nine patients were using assist-control mode MV with the mean applied positive end-expiratory pressure, 9 +/- 4.6 cmH2O and the mean tidal volume, 361 +/- 63.7 ml at the diagnosis of PTX. Two patients died as a result of MV-associated PTX and their systolic pressure was below 80 mmHg and heart rates were less than 80/min. Ten patients were treated by chest tube insertion, and 1 patient was treated by percutaneous pigtail catheter insertion. CONCLUSIONS: PTX can develop in patients undergoing MV, and may cause death. Early recognition and treatment are necessary to prevent hemodynamic compromise in patients who develop PTX.
