Background : Pulmonary tuberculosis is frequently accompanied with complications such as bronchiectasis, cavities, fibrosis and a deterioration of the lung function. However, there is little information available on the pathogenesis of these complications in pulmonary tuberculosis. Among the many factors involving in tissue remodeling, transforming growth factor-${\beta}1$ ($TGF-{\beta}1$) is a potent stimulus of the extracellular matrix fomation and a mediator of potential relevance for airway wall remodeling. Therefore, this study examined the relationship between the radiological changes and the $TGF-{\beta}1$ level in patients with pulmonary tuberculosis. Methods : Serum and bronchoalveolar lavage fluid (BALF) were collected from total of 35 patients before treating them for active pulmonary tuberculosis, and the $TGF-{\beta}1$ levels were measured using an enzyme-linked immunosorbent assay (ELISA). The BALF levels were recalculated as the epithelial lining fluid (ELF) levels using the albumin method. pulmonary function test (PFT) and high resolution computed tomography (HRCT) were performed before and after treatment. Results : There was a strong correlation between the serum $TGF-{\beta}1$ level and the presence of cavities (r=0.404, p=0.006), even though the BAL $TGF-{\beta}1$ level showed a weak correlation with complications. In addition, there was no correlation between the $TGF-{\beta}1$ levels before treatment and the changes in the PFT and HRCT during treatment. Conclusion : There is a correlation between the serum $TGF-{\beta}1$ level and cavity formation in pulmonary tuberculosis before treatment. However, further study will be needed to confirm this.

Cough is one of the most common symptom of many respiratory diseases. The Korean Academy of Tuberculosis and Respiratory Diseases organized cough guideline committee and cough guideline was developed by this committee. The purpose of this guideline is to help clinicians to diagnose correctly and treat efficiently patients with cough. In this article, we have stated recommendation and summary of Korean cough guideline. We also provided algorithm for acute, subacute, and chronic cough. For chronic cough, upper airway cough syndrome (UACS), cough variant asthma (CVA), and gastroesophageal reflux disease (GERD) should be considered. If UACS is suspicious, first generation anti-histamine and nasal decongestant can be used empirically. In CVA, inhaled corticosteroid is recommended in order to improve cough. In GERD, proton pump inhibitor is recommended in order to improve cough. Chronic bronchitis, bronchiectasis, bronchiolitis, lung cancer, aspiration, angiotensin converting enzyme inhibitor, habit, psychogenic cough, interstitial lung disease, environmental and occupational factor, tuberculosis, obstructive sleep apnea, peritoneal dialysis, and idiopathic cough can be also considered as cause of chronic cough. Level of evidence for treatment is mostly low. Thus, in this guideline, many recommendations are based on expert opinion. Further study regarding treatment for cough is mandatory.
Background: Many studies have demonstrated the various therapeutic options for treating hemoptysis caused by inflammatory lung disease. However, there is debate over the surgical management of the ongoing hemoptysis. Therefore, we evaluated the clinical results of pulmonary resection that was done due to hemoptysis in patients with concomitant inflammatory lung disease. Material and Method: We performed a retrospective analysis of 75 patients who received pulmonary resection for hemoptysis and concomitant inflammatory lung disease between 2001 and 2007. The mean age was $52.1{\pm}12.5$ years old, and the male; female ratio was 52:23. Result: The underlying disease was aspergilloma in 30 patients (40%), pulmonary tuberculosis in 20 patients, bronchiectasis in 18 patients and other causes in 7 patients. The surgical treatment included lobectomy in 55 patients, bilobectony in 2 patients, pneumonectomy in 17 patients and wedge resection in 1 patient. There were 3 early deaths, and the causes of death were pneumonia in 1 patient and BPF in 2 patients. The early mortality was statistically higher for such risk factors as a preoperative Hgb level <10 g/dL, COPD and an emergency operation. Conclusion: In conclusion, pulmonary resection for treating hemoptysis showed the acceptable range of mortality and it was an effective method for the management of hemoptysis in patients with inflammatory lung disease. However, relatively high rates of mortality and morbidity were noted for an emergency operation, and so meticulous care is needed in this situation.
Background : Bronchoscopy is a useful diagnostic tool, for accurate localization of the bleeding site and the management of hemoptysis. However, there is some controversy about the optimal timing of bronchoscopy. Method : To determine the optimal timing of bronchoscopy in hemoptysis, we reviewed the medical records of 118 patients and analyzed the following relationships amongst simple chest PA findings, namely, the duration and amount of hemoptysis, and the timing of bronchoscopy retrospectively. Results : The major causes of hemoptysis were active tuberculosis(28.8%), inactive tuberculosis(10.2%), bronchiectasis(17.0%), lung cancer(7.6%), and aspergilloma(7.6%). Localization of the bleeding focus by bronchoscopy was possible in 87.5% (21/24 cases) during active bleeding, and it was possible in 40.4% after bleeding had stopped(p<0.05). The localization rate of bleeding focus was 59.8% when the chest PA showed certain abnormalities, but it decreased to 27.8% when the chest PA finding was normal(p<0.05). When chest PA showed diffuse abnormalities or its finding was normal, the localization rate of bleeding focus significantly increased if bronchoscopy was performed during bleeding or within 48 hours of the cessation of active bleeding. The localization rate was higher as the amount of hemoptysis became larger(p<0.05). The localization rate of early bronchoscopy(during bleeding or within 48 hours of the cessation of active bleeding) was significantly higher when the duration of hemoptysis was less than 1 week, but there was no advantage if the duration was 1 week or longer. Early bronchoscopy was also necessary to localize the bleeding focus for surgical resection in 4 patients, and the bronchoscopy itself was therapeutic in 1 patient whose bleeding was successfully managed with thrombin-application via bronchoscope. Conclusion : It is concluded that flexible bronchoscopy is useful at not only localizing the bleeding focus but also in preparing a therapeutic plan, and early bronchoscopy is more favorable in hemoptysis.

Background : Diffuse panbronchiolitis(DPB) is a chronic inflammatory lung disease of unknown etiology which has characteristic clinical, radiological and pathological features, and is distinguished from bronchial asthma, chronic bronchitis, pulmonary emphysema, bronchiectasis, or alveolitis. Clinically, patients with DPB have chronic cough, purulent sputum, exertional dyspnea, and finally respiratory failure. Until a few years ago, the prognosis of DPB had been thought to be very grave, because there had been no effective treatment for the disease. But recent1y, low-dose long-term erythromycin was found to be very effective on DPB. Even though DPB is prevalent in Japan, and is known to be rare outside of Japan, we have a1ready reported the clinical features of 16 DPB cases in Korea. We tried low-dose long-term erythromycin on DPB patients and analyzed the clinical effect of erythromycin. Methods : We analyzed the changes of subjective symptoms, physical signs, pulmonary function tests and chest X-rays on 14 DPB patients with more than 6 months erythromycin treatment during the period from September 1989 to August 1992 in Seoul National University Hospital. Results : 1) Subjective symptoms improved in all patients within 2-3 months, and 54.5% of the patients showed no symptom after one year of treatment. 2) Crackles and wheezing decreased in 92.9% of the patients after 3 months and completely disapppeared in 63.5% of the patients after one year of treatment. 3) FVC and FEV1 increased remarkably during the first 3 months, and slowly increased thereafter, reaching normal level after one year of treatment. 4) Small nodular lesions on chest X-ray decreased in all patients, and chest PA was normal in 36.4% of the patients after one year of treatment. 5) There was side effect in one patient, stopping medication because of dyspepsia. One patient stopped medication because of no symptom after 16 months of treatment, but her symptom recurring after one month, improving again after retreatment. Conclusion: Low-dose long-term erythromycin showed ramarkable effectiveness on DPB. Further studies are needed on the mechanism of the drug and the duration of the treatment.
Hyperimmunoglobulin E syndrome (HIES) is a rare immunodeficiency disease which is characterized by high serum IgE levels, eczema, and recurrent infections. Herein we present the case of a patient with HIES associated with STAT3 gene ($stat3$) mutation. A 16 year-old girl was admitted to our hospital due to hemoptysis caused by pneumonia with bronchiectasis. She had a history of recurrent skin and respiratory tract infections, such as pneumonia caused by MRSA (methicillin-resistant $Staphylococcus$$aureus$) and $Pseudomonas$$aeruginosa$. On physical examination, a broad round shaped nose, oral thrush, and chronic eczematous skin rash over her whole body were found. Laboratory data showed an elevated eosinophil count ($750/{\mu}L$) and total IgE level (5,001 U/mL). The patient's National Institutes of Health (NIH) score for HIES was 44. Direct sequencing of the STAT3 gene revealed that the patient was heterozygous for a missense mutation in the DNA binding domain of the STAT3 protein (c.1144C>T, p. Arg382Trp). HIES should be suspected in patients with recurrent infections and can be confirmed by clinical scoring and genetic analysis.
Background: Intralobar and extralobar pulmonary sequestrations have been considered as congenital lesions that occur at different stages of embryonic life. However, most cases of intralobar pulmonary sequestration (IPS) seem to have an acquired origin, as they are absent in infants and associated anomalies are relatively, uncommon among them. Material and Method: The cases of 25 patients who were diagnosed as IPS after surgical resection from December, 1985 to July, 2002 were included in this study. The medical records wire retrospectively reviewed and the clinical characteristics were age at operation; gender; symptoms at presentation; presence of congenital anomalies; combined diseases; preoperative studies and diagnosis; location of the lesion; method of surgical resection; origin, size and numbers of aberrant artery; histopathological findings; and postoperative complications. Result: There were 17 (68%) female patients and 8 (32%) male patients, their ages ranged from 1 to 57 and mean value was 23 years old. Though 14 patients (56%) complained of respiratory symptoms such as pneumonia and recurrent respiratory infections, a large number of patients (44%) were asymptomatic or had chest pain only when the lesion was discovered. Only 8 patients (32%) were diagnosed as pulmonary sequestration preoperatively and 8 (32%) were suspected as mediastinal or lung tumor, 5 (20%) were congenital or acquired cystic lung disease, and 4 (16%) were lung abscess or bronchiectasis, respectively. The majority of aberrant arteries (86.4%) confirmed during the operation were originated from thoracic aorta and 2 were thoracic and abdominal aorta, 1 was abdominal aorta, respectively. The younger patients (less than 10 years old) had more other congenital anomalies (30% vs 6.7%) but the proportion of congenital IPS was not significantly different (10% vs 6.7%, p>0.05) compared with elder patients. Histopathologically, almost all lesions showed chronic inflammation, cystic changes and similar pleural adhesions regardless of age. Conclusion: The large portion of the patients with IPS (44%) was clinically asymptomatic or presented non-respiratory symptoms at diagnosis and likely to be diagnosed as mediastinal or lung tumor especially in elder patients. Though the younger patients had more other congenital anomalies, most cases of IPS proved to be acquired lesions in terms of the histopathlogical findings and the proportion of congenital evidences.

Background : Mycobacterium abscessus is the most common respiratory pathogen in rapidly growing mycobacteria and is resistant to all of the first-line antituberculosis drugs. This report describes the clinical and radiographic characteristics in patients with pulmonary disease caused by M. abscessus. Materials and Methods : Twelve patients with pulmonary disease caused by M. abscessus who fulfilled the 1997 American Thoracic Society diagnostic criteria for a nontuberculous mycobacterial pulmonary infection were observed over a five-and-a-half year period. The clinical characteristics and chest radiographic findings were analyzed, retrospectively. Results : The patients were predominantly female(11/12, 92%) and nonsmokers(12/12, 100%). Coughing (10/12, 83%), sputum(10/12, 83%) and hemoptysis(10/12, 83%) were the common symptoms and they had prolonged periods from the onset of symptoms to the diagnosis of their disease(median 6.5 years). Eleven (92%) patients had a previous history of being treated for pulmonary tuberculosis. The sputum specimens were acid-fast bacilli smear-positive in all patients. All patients were administered antituberculosis drugs. Six (50%) patients were treated with second-line antituberculosis drugs on account of persistent smear-positive sputum specimens. The chest radiographs showed that reticulonodular opacities(11/12, 92%) were the most common pattern of abnormality, followed by cavitary lesions(5/12, 42%). The computed tomography findings suggested bronchiolitis from the centrilobular nodules with a tree-in-bud appearances(9/10, 90%) and bronchiectasis (9/10, 90%) were the most common, followed by well-defined nodules smaller than 10-mm in diameter(7/10, 70%). Conclusions : M. abscessus pulmonary disease should be recognized as a cause of chronic mycobacterial lung disease, and respiratory isolates should be assessed carefully.

Background : Pulmonary sequestration is a rare congenital malformation, which is manifested by formation of nonfunctioning lung tissue lacking normal communication with the tracheobronchial tree. The preoperative diagnostic rate has been relatively low, and without consideration of pulmonary sequestration, unexpected bleeding from aberrant vessels may be a serious problem during the operation. The purpose of our study is to describe the clinical features of pulmonary sequestration based on a review of 15 cases treated by operation. Method : Fifteen patients with pulmonary sequestration who had undergone surgical treatment from 1991 through May 1996 at Yongdong Severance Hospital and Severance Hospital were reviewed retrospectively. Results : The mean age of the patients was 22.5 years (range 5~57), and male to female ratio was 9 : 6. Clinical presentations varied from recurrent respiratory infections such as fever, cough, and sputum or chest pain to no symptom. The chest simple X-rays showed multicystic shadow(10/15) and solid mass-like shadow(5/15). The chest CT scans, done in twelve cases, showed multicystic lesion with or without lung infiltration(8/12), solid mass-like lesion(4/12), The chest MRIs, done in three cases, revealed the aberrant arteries originating from descending aorta(2/3). Aortograms, done in four cases, showed the aberrant arteries originating from descending thoracic aorta(2/4), abdominal aorta(I/4), and intercostal artery(1/4). and the venous returns were via the pulmonary veins. Pulmonary sequestration was considered preoperatively in six patients of fifteen. Other preliminary diagnosis were lung tumor(3/15), lung abscess(21/15), bronchiectasis(2/15), and mediastinal tumor(2/15). In the operative findings, twelve cases were of intralobar type and three cases of extralobar type. The left lower lobe was most often affected(9/15) and one extralobar sequestration was in the pericardium. The aberrant arteries originated from descending thoracic aorta(6/15), abdominal aorta(1/15), internal thoracic arteries (2/15), intercostal artery(1/15), pericardiophrenic artery(1/15), but in four cases, the origins could not be defined. There was no mortality or complication postoperatively. Conclusion : In our study, preoperative diagnostic rate was relatively low, and clinical features were similar to previous reports. Preoperative vigorous diagnostic approach including aortography is strongly advocated not only for its diagnostic value, but also for accurate localization of the aberrant vessels, which is major concern to surgical procedure.
Background: Mixed obstructive and restrictive pattern of spirometry can not be concluded in the presence of true restrictive disorders because pure obstructive disorders can also show reduced vital capacity. However, it is not known how many patients with mixed spirometric pattern really have restrictive disorders in Korea whose pattern of pulmonary diseases is somewhat different from foreign countries. To answer this question, I performed this study and tried to answer it according to diseases in addition. Method: Test results from 413 patients who undergone both spirometry and lung volume measurements on the same visit from August 1, 1998 to July 31, 1999 were included. Spirometry data were classified as mixed obstructive-restrictive pattern when spirometry showed '$FEV_1/FVC$<70% (<65% if age$\geq$60)' and FVC<80% of predicted value'. TLC by the method of nitrogen washout was considered as gold standard to diagnose restrictive disorders in which TLC is less than 80% of predicted value. Results: Out of 404 patients who could be evaluated, 58 had mixed pattern of spirometry. 58 patients were suffered from airway diseases(39 patients) such as COPD(22 patients, 38%), asthma(11, 19%), bronchiectasis (6,10%), and sequelae of pulmonary tuberculosis(15, 26%) or other diseases(4,7%). Only 18 out of 58(31%) were confirmed to have true restrictive disorders by TLC. The proportion of true restrictive disorders was different according to diseases, 20.5%(8/39patients) in patients with airway diseases and 53.3%(8/15) with sequelae of pulmonary tuberculosis(p<0.05). Conclusion: Many patients whose spirometry showed mixed pattern didn't have restrictive disorders but had pure obstructive disorders. This was true for more patients with airway diseases. Therefore it would be prudent that lung volume be tested to diagnose restrictive disorders in patients with mixed spirometric pattern.
