Abstract
BACKGROUND AND OBJECTIVE Outside clinical trials, there is limited long-term data following bronchial thermoplasty (BT). In a cohort of real-world severe asthmatics in an era of biological therapy, we sought to evaluate the safety and efficacy of BT 5 years post-treatment. METHODS Every patient treated with BT at two Australian tertiary centres were recalled at 5 years, and evaluated by interview and record review, Asthma Control Questionnaire (ACQ), spirometry and high-resolution CT Chest. CT scans were interpreted using the modified Reiff and BRICS CT scoring systems for bronchiectasis. RESULTS Fifty-one patients were evaluated. At baseline, this cohort had a mean age of 59.0 ± 11.8 years, mean ACQ of 3.0 ± 1.0, mean FEV1 of 55.5 ± 18.8% predicted, and 53% were receiving maintenance oral steroids in addition to triple inhaler therapy. At 5 years, there was a sustained improvement in ACQ scores to 1.8 ± 1.0 (p < 0.001). Steroid requiring exacerbation frequency was reduced from 3.8 ± 3.6 to 1.0 ± 1.6 exacerbations per annum (p < 0.001). 44% of patients had been weaned off oral steroids. No change in spirometry was observed. CT scanning identified minor degrees of localized radiological bronchiectasis in 23/47 patients with the modified Reiff score increasing from 0.6 ± 2.6 at baseline to 1.3 ± 2.5 (p < 0.001). However, no patients exhibited clinical features of bronchiectasis, such as recurrent bacterial infection. CONCLUSION Sustained clinical benefit from BT at 5 years was demonstrated in this cohort of very severe asthmatics. Mild, localized radiological bronchiectasis was identified in a portion of patients without clinical features of bronchiectasis.

Abstract
Over the last decade, deep learning (DL) has contributed a paradigm shift in computer vision and image recognition creating widespread opportunities of using artificial intelligence in research as well as industrial applications. DL has been extensively studied in medical imaging applications, including those related to pulmonary diseases. Chronic obstructive pulmonary disease, asthma, lung cancer, pneumonia, and, more recently, COVID-19 are common lung diseases affecting nearly 7.4% of world population. Pulmonary imaging has been widely investigated toward improving our understanding of disease etiologies and early diagnosis and assessment of disease progression and clinical outcomes. DL has been broadly applied to solve various pulmonary image processing challenges including classification, recognition, registration, and segmentation. This paper presents a survey of pulmonary diseases, roles of imaging in translational and clinical pulmonary research, and applications of different DL architectures and methods in pulmonary imaging with emphasis on DL-based segmentation of major pulmonary anatomies such as lung volumes, lung lobes, pulmonary vessels, and airways as well as thoracic musculoskeletal anatomies related to pulmonary diseases.

Non-cystic fibrosis bronchiectasis: a retrospective review of clinical, radiological, microbiological and lung function profile at a tertiary care center of low-middle income country. Monaldi Arch Chest Dis 2023. [PMID: 37700688 DOI: 10.4081/monaldi.2023.2718] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/18/2023] [Accepted: 08/28/2023] [Indexed: 09/14/2023] Open
Abstract
Non-cystic fibrosis (non-CF) bronchiectasis has emerged as a significant respiratory disease in developing countries. Given the variation in causes and clinical characteristics across different regions, it is necessary to conduct studies in regions with limited data such as low-middle income countries (LMIC). The aim of the study was to investigate the underlying causes, clinical presentation, etiology, lung function and imaging in patients with bronchiectasis who sought treatment at a tertiary care hospital in a LMIC. We conducted retrospective observational study at the Aga Khan University, Pakistan. Adult patients diagnosed with non-CF bronchiectasis on high-resolution computed tomography scan between 2000 and 2020 were included. We evaluated the etiology, clinical characteristics, microbiology, radiology and spirometric pattern of these patients. A total of 340 patients were included with 56.5% being female and 44.7% aged over 60 years. Among them, 157 (46.2%) had experienced symptoms for 1-5 years. The most common spirometric pattern observed was obstructive impairment (58.1%). Previous tuberculosis (TB) (52.94%) was the most common etiology followed by allergic bronchopulmonary aspergillosis (7.64%). Bilateral lung involvement on HRCT scan was found in 63.2% of patients. Pseudomonas aeruginosa was the most frequently identified organism (38.75%) among 240 patients with available specimens. Patients with P. aeruginosa infections had a significantly higher number of exacerbations (p=0.016). There was a significant difference (p<0.001) in P. aeruginosa growth among different etiologies. In conclusion, post-TB bronchiectasis was the most common cause of non-CF bronchiectasis in our study population. P. aeruginosa was the predominant organism, and 63.2% of the patients exhibited bilateral lung involvement. Since P. aeruginosa growth and extensive lung involvement have been associated with poor prognosis and increased mortality risk, we recommend close follow ups of these patients to improve quality of life and survival in developing countries like Pakistan.

Abstract
Non-cystic fibrosis bronchiectasis represents a heterogenous spectrum of disorders characterised by an abnormal and permanent dilatation of the bronchial tree associated with respiratory symptoms. To date, diagnosis relies on computed tomography (CT) evidence of dilated airways. Nevertheless, definite radiological criteria and standardised CT protocols are still to be defined. Although largely used, current radiological scoring systems have shown substantial drawbacks, mostly failing to correlate morphological abnormalities with clinical and prognostic data. In limited cases, bronchiectasis morphology and distribution, along with associated CT features, enable radiologists to confidently suggest an underlying cause. Quantitative imaging analyses have shown a potential to overcome the limitations of the current radiological criteria, but their application is still limited to a research setting. In the present review, we discuss the role of imaging and its current limitations in non-cystic fibrosis bronchiectasis. The potential of automatic quantitative approaches and artificial intelligence in such a context will be also mentioned.

Abstract
Cough is the most common respiratory symptom that can have various causes. It is a major clinical problem that can reduce a patient’s quality of life. Thus, clinical guidelines for the treatment of cough were established in 2014 by the cough guideline committee under the Korean Academy of Tuberculosis and Respiratory Diseases. From October 2018 to July 2020, cough guidelines were revised by members of the committee based on the first guidelines. The purpose of these guidelines is to help clinicians efficiently diagnose and treat patients with cough. This article highlights the recommendations and summary of the revised Korean cough guidelines. It includes a revised algorithm for the evaluation of acute, subacute, and chronic cough. For a chronic cough, upper airway cough syndrome (UACS), cough variant asthma (CVA), and gastroesophageal reflux disease (GERD) should be considered in differential diagnoses. If UACS is suspected, first-generation antihistamines and nasal decongestants can be used empirically. In cases with CVA, inhaled corticosteroids are recommended to improve cough. In patients with suspected chronic cough due to symptomatic GERD, proton pump inhibitors are recommended. Chronic bronchitis, bronchiectasis, bronchiolitis, lung cancer, aspiration, intake of angiotensin-converting enzyme inhibitor, intake of dipeptidyl peptidase-4 inhibitor, habitual cough, psychogenic cough, interstitial lung disease, environmental and occupational factors, tuberculosis, obstructive sleep apnea, peritoneal dialysis, and unexplained cough can also be considered as causes of a chronic cough. Chronic cough due to laryngeal dysfunction syndrome has been newly added to the guidelines.

Medicine (Baltimore) 2021; 100:e25193. [PMID: 33832079 PMCID: PMC8036049 DOI: 10.1097/md.0000000000025193] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/26/2020] [Accepted: 02/17/2021] [Indexed: 01/05/2023] Open
Abstract
The incidence of pulmonary nontuberculous mycobacterial (NTM) infection is high in patients with underlying lung disease such as bronchiectasis. Although previous studies have reported many risk factors contributing to the development of NTM-lung disease (LD), only a few reports on the relationship of the characteristics of patients, such as body mass index (BMI), skeletal mass, and fat mass, with NTM-LD have been published. We aimed to investigate the association between these parameters and NTM-LD in patients with bronchiectasis.A monocentric retrospective study in a university hospital was conducted over 4 years (2013-2016). Parameters including BMI, skeletal mass, and fat mass were measured using bioelectrical impedance analysis in noncystic fibrosis bronchiectasis patients. Patients were grouped by the presence or absence of NTM-LD, and the differences in BMI, skeletal mass, and fat mass between the 2 groups were compared. In the NTM-LD group, the progression of disease was also followed.Two hundred forty-five patients with bronchiectasis were enrolled in the study. One hundred six subjects (48%) had NTM-LD. These patients with NTM-LD were predominantly female, and had a significantly lower body weight (58.20 ± 8.84 vs 54.16 ± 8.99, P < .001), BMI (22.67 ± 3.04 vs 21.20 ± 2.59 kg/m2, P < .001), fat mass (16.19 ± 6.60 vs 14.23 ± 5.79, P = .013), and fat mass index (FMI; 6.79 ± 2.70 vs 5.57 ± 2.27 kg/m2, P < .001). Multivariate regression analysis showed that both female sex and lower FMI but not skeletal muscle index were independent risk factors for NTM-LD after adjusting for age, bronchiectasis severity index, and BMI (odds ratio 3.86 (1.99-7.78); 0.72 (0.63-0.82), P < .001, respectively).Our results suggest that lower FMI may contribute to susceptibility to NTM infection in patients with bronchiectasis, independent of age or its severity.

Abstract
Diagnosis of bronchiectasis is usually made using chest computed tomography (CT) scan, the current gold standard method. A bronchiectatic airway can show abnormal widening and thickening of its airway wall. In addition, it can show an irregular wall and lack of tapering, and/or can be visible in the periphery of the lung. Its diagnosis is still largely expert based. More recently, it has become clear that airway dimensions on CT and therefore the diagnosis of bronchiectasis are highly dependent on lung volume. Hence, control of lung volume is required during CT acquisition to standardise the evaluation of airways. Automated image analysis systems are in development for the objective analysis of airway dimensions and for the diagnosis of bronchiectasis. To use these systems, clear and objective definitions for the diagnosis of bronchiectasis are needed. Furthermore, the use of these systems requires standardisation of CT protocols and of lung volume during chest CT acquisition. In addition, sex- and age-specific reference values are needed for image analysis outcome parameters. This review focusses on today's issues relating to the radiological diagnosis of bronchiectasis using state-of-the-art CT imaging techniques. Bronchiectasis diagnosis is expert based. Clear definitions, standardisation of lung volume and CT protocols, and reference values are needed to allow automated image analysis for its diagnosis and to be used for clinical management and clinical studies.http://bit.ly/35vASqz

Abstract
Objectives To identify the etiology of non-cystic fibrosis bronchiectasis (NCFB), to assess the clinical presentation, radiological findings, and microbiological profile of patients presenting with a diagnosis of bronchiectasis in a tertiary care center of Pakistan. Methods This was a prospective observational cohort study where patients with a diagnosis of bronchiectasis proven by high-resolution computed tomography (HRCT) were evaluated for etiology, clinical characteristics, microbiology, radiology, spirometric profile, and in-hospital outcomes. Results During the study period, 196 patients were diagnosed with NCFB. The majority of the patients were men 76.5% (n = 150) and 83.6% (n = 163) of the total patients were younger than 60 years of age. The majority of these patients (58.7%, n = 111) had a duration of symptoms between 5-10 years. The etiology of bronchiectasis was identified in 92.9% of cases. Post-infectious bronchiectasis was the most common cause (67.8%, n = 133), followed by chronic obstructive pulmonary disease (COPD) (9.2%, n = 18), and allergic bronchopulmonary aspergillosis (ABPA) (7.1%, n = 14). Among the post infectious causes, a history of TB was present in 85% (n = 114/133) of patients. Obstructive impairment was the most common spirometric pattern, observed in 68.9% (n = 135) of patients. Pseudomonas aeruginosa was the most commonly isolated organism (36.2%, n = 71). Hemoptysis was the most frequent complication found in 20.9% of patients (n = 41). Out of these 196 patients, 94.4% (n = 185) received medical management and were discharged from the hospital. Respiratory failure was significantly associated with the Pseudomonas group as compared to non-pseudomonas group [(n = 21 (29%) vs n = 18 (14.4%) p = 0.01]. During hospitalization seven patients (3.6%) were died because of respiratory failure. Conclusions Post TB bronchiectasis was the leading cause of non-cystic fibrosis (CF) bronchiectasis in this cohort, with Pseudomonas was the commonest pathogen isolated from the respiratory specimen, which was significantly associated with respiratory failure. On spirometry, obstructive impairment was found in the majority of patients and hemoptysis was the most frequent complication.

Abstract
PURPOSE OF REVIEW Noncystic fibrosis bronchiectasis is a challenging disease which carries a heavy healthcare burden and significant mortality and morbidity. This review highlights the challenges in the diagnosis of bronchiectasis and discusses the management strategies and research opportunities in this field. RECENT FINDINGS The challenges in the management of bronchiectasis appear to be multifactorial, arising from both etiological heterogeneity and disease-specific management. Frequent inflammation and infections not only lead to progressive respiratory failure but also increase the risk of cardiovascular complications. No therapies are approved specifically for adult bronchiectasis, but new guidelines and recent studies outline strategies for control of infection and inflammation and for prevention of frequent exacerbations to improve overall prognosis. SUMMARY Recent studies in the management of bronchiectasis are encouraging. Advances have been made in understanding both disease heterogeneity and best practices for care; interventions such as daily mucociliary clearance, eradication of colonized microbial organisms, and control of inflammation may result in favorable outcomes.

Abstract
BACKGROUND The failure of mucus clearance in bronchiectasis can be improved by chest physiotherapy or/and mucoactive agents. AIM To assess the effects of long-term use of carbocysteine on frequency and duration of exacerbations in patients with bronchiectasis. METHODS We performed an observational, non-randomized, open study (a real-life study) including 64 patients with bronchiectasis divided into two groups, examined group (EG) and control group (CG). All participants were treated with appropriate treatment for the stable disease, but in the study, subjects of EG two capsules 375 mg carbocysteine three times a day was added over three months. Daily diary cards realised collection of data regarding the occurrence and duration of exacerbation in all study subjects. RESULTS Over the study period 43 exacerbations were documented, 17 in the EG and 26 in the CG, 10 (23.4%) of which required hospital treatment (four in the EG [23.5%] and six in the CG [23.1%]). A mean number of exacerbations over the study period was significantly lower in the EG (0.5 ± 0.1) as compared to their mean number in the CG (0.8 ± 0.2) (P = 0.0000). Mean duration of exacerbations expressed in days needed for complete resolution of symptoms or return of the symptoms to their baseline severity in the EG was significantly shorter than the mean duration of exacerbations in the CG (10.1 ± 2.6 vs 12.8 ± 2.1; P = 0.0000). The frequency of adverse effects, i.e. mild gastrointestinal manifestations and headache which did not require discontinuation of the treatment, in the EG during the study period was 15.6%. CONCLUSION Our findings indicated positive effects of carbocysteine regarding the frequency and duration of exacerbations, as well as its good tolerability in the patients with bronchiectasis.

[PMID: 31530430 DOI: 10.1016/j.hrtlng.2019.09.004] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/14/2019] [Revised: 09/05/2019] [Accepted: 09/06/2019] [Indexed: 10/26/2022]
Abstract
BACKGROUND A few studies have implied that patients with bronchiectasis have a more inactive lifestyle than healthy counterparts do. The main objective of this study was to compare physical activity (PA) levels subjectively and objectively between patients with bronchiectasis and healthy individuals using an accelerometer and a questionnaire. METHODS The study included 41 patients with bronchiectasis aged 18-65 years and 35 healthy age- and sex-matched control subjects. The PA level was assessed objectively using a multisensorial PA monitor, the SenseWear Armband (SWA), and subjectively with the International Physical Activity Questionnaire (IPAQ). All participants performed the incremental shuttle walk test (ISWT) for the assessment of exercise capacity. Pulmonary function, dyspnea, severity of bronchiectasis, respiratory and peripheral muscle strength, and quality of life were assessed. RESULTS The pulmonary function test parameters, respiratory and peripheral muscle strength, exercise capacity, step count, moderate- and vigorous-intensity PA duration were significantly lower in patients with bronchiectasis than in the healthy control group (p < 0.05). Sedentary, moderate, vigorous, and total PA duration measured using the SWA were higher than those obtained using the IPAQ (p < 0.05). CONCLUSIONS Patients with bronchiectasis have a reduced PA level compared with healthy counterparts. The IPAQ (based on the subjective estimation of PA) outcomes differed from the SWA outcomes, reinforcing the necessity for a disease-specific PA questionnaire. IPAQ underestimates the physical activity level compared with objective measurements.

[PMID: 31295770 DOI: 10.1111/crj.13054] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/07/2019] [Revised: 06/25/2019] [Accepted: 07/07/2019] [Indexed: 11/30/2022]
Abstract
INTRODUCTION Quality of life (QoL) is known to be impaired in patients with bronchiectasis, which is generally attributed to exacerbations and chronic pulmonary symptoms. The aim of this study was to determine if aetiology and disease severity are associated with QoL in bronchiectasis. METHODS We conducted a retrospective analysis of clinical stable patients with bronchiectasis. Diagnostic workup into the aetiology of bronchiectasis was conducted according to the current guidelines. QoL was measured by QoL-B questionnaire (QoL-B), data on sputum microbiology, pulmonary function tests and the disease severity were obtained. RESULTS The aetiology of bronchiectasis was investigated in the total of 200 patients. The most commonly identified aetiologies were post-infective (39.5%) and idiopathic (12.5%). Patients with chronic obstructive pulmonary disease (COPD)-related bronchiectasis showed a significant lower QoL (P < .05) as compared to the other aetiologies. In the total population, an increasing disease severity as measured by FACED, E-FACED and the bronchiectasis severity index was correlated with a lower QoL. CONCLUSIONS Our results showed that QoL in bronchiectasis is related both to aetiology, with worse QoL in COPD-related bronchiectasis, and to disease severity, which suggests more attention in advance for these specific patient groups with bronchiectasis.

Abstract
BACKGROUND Bronchiectasis is a chronic pulmonary disease characterized by progressive and irreversible bronchial dilatation. The aim of the present study was to investigate the etiologies and clinical features of bronchiectasis in Korean children. METHODS We performed a retrospective review of the medical records for children diagnosed with bronchiectasis between 2000 and 2017 at 28 secondary or tertiary hospitals in South Korea. RESULTS A total of 387 cases were enrolled. The mean age at diagnosis was 9.2 ± 5.1 years and 53.5% of the patients were boys. The most common underlying cause of bronchiectasis was preexisting respiratory infection (55.3%), post-infectious bronchiolitis obliterans (14.3%), pulmonary tuberculosis (12.3%), and heart diseases (5.6%). Common initial presenting symptoms included chronic cough (68.0%), recurrent pneumonia (36.4%), fever (31.1%), and dyspnea (19.7%). The most predominantly involved lesions were left lower lobe (53.9%), right lower lobe (47.1%) and right middle lobe (40.2%). No significant difference was observed in the distribution of these involved lesions by etiology. The forced expiratory volume in 1 s (FEV1) levels were lowest in cases with interstitial lung disease-associated bronchiectasis, followed by those with recurrent aspiration and primary immunodeficiency. CONCLUSIONS Bronchiectasis should be strongly considered in children with chronic cough and recurrent pneumonia. Long-term follow-up studies on pediatric bronchiectasis are needed to further clarify the prognosis and reduce the disease burden in these patients.

Abstract
In human medicine, CT is widely used to detect changes in bronchial luminal diameter. The diameter of the artery that runs adjacent to the bronchus does not change dramatically along the airway path, such that this artery can be used as a reference to detect changes in the bronchial luminal diameter. The bronchoarterial ratio is increasingly used in veterinary medicine for the detection of lower airway diseases in animals. The purpose of this study was to establish the bronchoarterial ratio in rhesus macaques. We used CT to evaluate 12 rhesus macaques (Macaca mulatta) without clinical signs of pulmonary diseases and measured the bronchoarterial ratio in the right and left superior, middle, inferior and cardiac lung lobes. The overall bronchoarterial ratio (mean ± 1 SD) at all 7 locations in the 12 macaques was 0.59 ± 0.05. Moreover, there was no correlation between the BA ratio and age or sex in the study population. However, the BA ratio and weight of animals showed positive linear correlation. In this study, we established the reference range for the bronchoarterial ratio in clinically healthy rhesus macaques. This ratio is consistent among lung lobes and between animals.

Abstract
Bronchiectasis are defined as an irreversible focal or diffuse dilatation of the bronchi and can be associated with significant morbidity. The prevalence is currently increasing, probably due to an increased use of thoracic computed tomography (CT). Indeed, the diagnosis relies on imaging and chest CT is the gold standard technique. The main diagnosis criterion is an increased bronchial diameter as compared to that of the companion artery. However, false positives are possible when the artery diameter is decreased, which is called pseudo-bronchiectasis. Other features such as the lack of bronchial tapering, and visibility of bronchi within 1cm of the pleural surface are also diagnostic criteria, and other CT features of bronchial disease are commonly seen. Thoracic imaging also allows severity assessment and long-term monitoring of structural abnormalities. The distribution pattern and the presence of associated findings on chest CT help identifying specific causes of bronchiectasis. Lung MRI and ultra-low dose CT and are promising imaging modalities that may play a role in the future. The objectives of this review are to describe imaging features for the diagnosis and severity assessment of bronchiectasis, to review findings suggesting the cause of bronchiectasis, and to present the new developments in bronchiectasis imaging.

Abstract
Bronchiectasis is a clinical and radiological diagnosis associated with cough, sputum production and recurrent respiratory infections. The clinical presentation inevitably overlaps with other respiratory disorders such as asthma and chronic obstructive pulmonary disease (COPD). In addition, 4-72% of patients with severe COPD are found to have radiological bronchiectasis on computed tomography, with similar frequencies (20-30%) now being reported in cohorts with severe or uncontrolled asthma. Co-diagnosis of bronchiectasis with another airway disease is associated with increased lung inflammation, frequent exacerbations, worse lung function and higher mortality. In addition, many patients with all three disorders have chronic rhinosinusitis and upper airway disease, resulting in a complex "mixed airway" phenotype.The management of asthma, bronchiectasis, COPD and upper airway diseases has traditionally been outlined in separate guidelines for each individual disorder. Recognition that the majority of patients have one or more overlapping pathologies requires that we re-evaluate how we treat airway disease. The concept of treatable traits promotes a holistic, pathophysiology-based approach to treatment rather than a syndromic approach and may be more appropriate for patients with overlapping features.Here, we review the current clinical definition, diagnosis, management and future directions for the overlap between bronchiectasis and other airway diseases.

Abstract
Background The prevalence rate of bronchiectasis in COPD is variable. Coexisting bronchiectasis and COPD may influence COPD severity and exacerbation. Objective We investigated whether bronchiectasis is associated with frequent or severe COPD exacerbation. Lower airway bacterial and mycobacterial infections are a possible mechanism for bronchiectasis. Materials and methods A cross-sectional study was conducted in 2013–2014. COPD exacerbations and hospitalizations were reviewed. Spirometry and CT were performed. COPD symptoms were assessed by using the COPD assessment test (CAT) and modified Medical Research Council (mMRC) dyspnea scale. Sputum inductions were performed and specimens were sent for microbiology. Results We recruited 72 patients. Global Initiative for Chronic Obstructive Lung Disease (GOLD) A, B, C, and D, were noted in 20%, 27.1%, 14.3%, and 38.6% of the patients, respectively. Frequent exacerbations (≥2) and/or ≥1 hospitalization in the previous year were observed in 40.3% of patients. Median mMRC of COPD with frequent and non-frequent exacerbations was 1.0 (range 1–2) and 2.0 (range 1–3), (p=0.002), respectively. Median CAT of COPD with frequent and non-frequent exacerbations was 20.5 (3–37) and 11.0 (2–32), (p=0.004), respectively. CT-detected bronchiectasis was observed in 47.2% of patients. Median mMRC of COPD with and without bronchiectasis was 1.0 (0–4) and 1.0 (0–4) (p=0.22), respectively. Median CAT of COPD with and without bronchiectasis was 16.2 (95% CI: 12.9–19.6) and 13.0 (3–37), (p=0.49), respectively. The lower post-bronchodilator forced expiratory volume in 1 second (FEV1) of COPD with frequent exacerbations than those without was noted (p=0.007). The post-bronchodilator forced expiratory volume at 1 second percent in patients with and without bronchiectasis was not different (p=0.91). After adjusting for gender, severity of airflow obstruction, severity of COPD symptoms, the odds ratio for bronchiectasis with frequent and/or severe exacerbation was 4.99 (95% CI: 1.31–18.94), (p=0.018). Neither bacterial nor mycobacterial airway infection was associated with bronchiectasis or frequent exacerbation. Conclusions Bronchiectasis is common in Thai COPD. It was associated with frequent exacerbation or hospitalization. Mycobacterial tuberculosis in COPD patients with bronchiectasis was uncommon.

Abstract
INTRODUCTION Bronchiectasis (BC) is a multidimensional and etiologically diverse disease and, therefore, no single parameter can be used to determine its overall severity and prognosis. In this regard, two different validated scores are currently used to assess the severity of non-cystic fibrosis bronchiectasis (NCFB): the FACED score and the Bronchiectasis Severity Index (BSI). OBJECTIVE To describe the etiology of NCFB and compare the results of the assessment of NCFB severity obtained via FACED and BSI scores. METHODS Retrospective study of demographic and clinical data of a convenience sample of NCFB patients attending the Functional Breathing Re-adaptation appointment at the Pneumology B Unit, University Hospital Center of Coimbra. All patients underwent evaluation of the variables incorporated in the FACED score (FEV1% predicted, age, chronic colonization by Pseudomonas aeruginosa, radiological extent of the disease, and dyspnea) and in the BSI (age, body mass index, FEV1% predicted, hospitalization and exacerbations before study, dyspnea, chronic colonization by P. aeruginosa and other microrganisms, and radiological extent of the disease). Statistical analysis of the data was performed using Microsoft Excel® and IBM SPSS® v23. RESULTS The sample included 40 patients, 22 females and 18 males, aged 39-87 years. Regarding the etiology of NCFB, we found: idiopathic (60%), post-infectious (20%), sequelae of pulmonary tuberculosis (12.5%) and primary immunodeficiency related (7.5%). According to the FACED score we found 20 patients (50%) with mild BC, 15 patients (37.5%) with moderate and 5 patients (12.5%) with severe BC. The frequency of patients with low, intermediate and high BSI was 13 (32.5%), 13 (32.5%) and 14 (35%), respectively in relation to derived BSI, Moreover, we observed a weak but statistically significant association between FACED and BSI scores: Fisher's exact test (p=0.004), tau-b de Kendall (0.469; p=0.001). The Kappa test (0.330; p=0.002) also shows us that there is 55% agreement between the two scales. CONCLUSION There is a small but significant correlation between the two scales: a tendency is observed for patients to be classified with a higher BSI compared to the FACED score. This can be explained by the fact that BSI (and not FACED) evaluates parameters including BMI, hospitalization and exacerbations before study, chronic colonization by other microorganisms and development of cystic bronchiectasis. Further studies should address how these scores may impact clinical practice.

Abstract
Non-cystic fibrosis bronchiectasis (NCFBE) is a chronic inflammatory lung disease characterized by irreversible dilation of the bronchi, symptoms of persistent cough and expectoration, and recurrent infective exacerbations. The prevalence of NCFBE is on the increase in the United States and Europe, but no licensed therapies are currently available for its treatment. Although there are many similarities between NCFBE and cystic fibrosis (CF) in terms of respiratory symptoms, airway microbiology, and disease progression, there are key differences, for example, in response to treatment, suggesting differences in pathogenesis. This review discusses possible reasons underlying differences in response to inhaled antibiotics in people with CF and NCFBE. Pseudomonas aeruginosa infections are associated with the most severe forms of bronchiectasis. Suboptimal levels of antibiotics in the lung increase the mutation frequency of P. aeruginosa and lead to the development of mucoid strains characterized by formation of a protective polysaccharide biofilm. Mucoid strains of P. aeruginosa are associated with a chronic infection stage, requiring long-term antibiotic therapy. Inhaled antibiotics provide targeted delivery to the lung with minimal systemic toxicity and adverse events compared with oral/intravenous routes of administration, and they could be alternative treatment options to help address some of the treatment challenges in the management of severe cases of NCFBE. This review provides an overview of completed and ongoing trials that evaluated inhaled antibiotic therapy for NCFBE. Recently, several investigators conducted phase 3 randomized controlled trials with inhaled aztreonam and ciprofloxacin in patients with NCFBE. While the aztreonam trial results were not associated with significant clinical benefit in NCFBE, initial results reported from the inhaled ciprofloxacin (dry powder for inhalation and liposome-encapsulated/dual-release formulations) trials hold promise. A more targeted approach could identify specific populations of NCFBE patients who benefit from inhaled antibiotics.

Abstract
Pulmonary diseases caused by nontuberculous mycobacteria (NTM) have increased over the last years and decades in Germany and also worldwide. Because the disease is more frequent in patients with immunodeficiencies and chronic respiratory diseases, e.g. bronchiectasis, advanced chronic obstructive lung disease (COPD) and cystic fibrosis (CF), an infection with mycobacteria should always be considered in this patient group. The detection in sputum alone is not an indication for treatment but the correct diagnosis should be based on the appropriate clinical symptoms as well as radiological and microbiological criteria. The diagnosis is often delayed because the symptoms are unspecific. The treatment of pulmonary NTM disease is difficult and tedious and for these reasons is often prematurely terminated. Adherence of treating physicians to the guidelines is also conspicuously low. Before starting treatment, it is important to carefully define the goals and clarify the risks and benefits of the treatment with the patient. As adverse toxic events can occur during treatment, it should be closely monitored. In the case of an infrequent pathogen or a severe course of the disease, referral to an NTM specialist center should be undertaken.

Abstract
This is the first guideline developed by the Saudi Thoracic Society for the diagnosis and management of noncystic fibrosis bronchiectasis. Local experts including pulmonologists, infectious disease specialists, thoracic surgeons, respiratory therapists, and others from adult and pediatric departments provided the best practice evidence recommendations based on the available international and local literature. The main objective of this guideline is to utilize the current published evidence to develop recommendations about management of bronchiectasis suitable to our local health-care system and available resources. We aim to provide clinicians with tools to standardize the diagnosis and management of bronchiectasis. This guideline targets primary care physicians, family medicine practitioners, practicing internists and respiratory physicians, and all other health-care providers involved in the care of the patients with bronchiectasis.

Abstract
INTRODUCTION The prevalence and awareness of bronchiectasis not related to cystic fibrosis (CF) is increasing and it is now recognized as a major cause of respiratory morbidity, mortality and healthcare utilization worldwide. The need to elucidate the early origins of bronchiectasis is increasingly appreciated and has been identified as an important research priority. Current treatments for pediatric bronchiectasis are limited to antimicrobials, airway clearance techniques and vaccination. Several new drugs targeting airway inflammation are currently in development. Areas covered: Current management of pediatric bronchiectasis, including discussion on therapeutics, non-pharmacological interventions and preventative and surveillance strategies are covered in this review. We describe selected adult and pediatric data on bronchiectasis treatments and briefly discuss emerging therapeutics in the field. Expert commentary: Despite the burden of disease, the number of studies evaluating potential treatments for bronchiectasis in children is extremely low and substantially disproportionate to that for CF. Research into the interactions between early life respiratory tract infections and the developing immune system in children is likely to reveal risk factors for bronchiectasis development and inform future preventative and therapeutic strategies. Tailoring interventions to childhood bronchiectasis is imperative to halt the disease in its origins and improve adult outcomes.

Abstract
There is evidence that coexisting bronchiectasis (BE) in patients with chronic obstructive pulmonary disease (COPD) aggravates the course of the disease. In this study, we aimed to evaluate the frequency and severity of bacterial exacerbations in COPD patients with BE. The frequency and duration of bacterial exacerbations treated in a 12-month period, as well as the duration of the exacerbation-free interval, were evaluated in 54 patients with COPD (Group D) who were diagnosed and assessed according to official recommendations. In 27 patients, BE was diagnosed by high-resolution computed tomography (HRCT), whereas an equal number of COPD patients who were confirmed negative for BE by HRCT, served as controls. We found a significantly higher mean number of exacerbations in a 12-month period in COPD patients with BE (2.9 ± 0.5), as compared to their mean number in controls (2.5 ± 0.3) (p = 0.0008). The mean duration of exacerbation, i.e. the mean number of days elapsed before complete resolution of the symptoms or their return to the baseline severity, was significantly longer in COPD patients with BE as compared to their mean duration in controls (6.9 ± 1.8 vs. 5.7 ± 1.4; p = 0.0085). In addition, the mean exacerbation-free interval expressed in days, in patients with COPD with BE, was significantly shorter than in COPD patients in whom BE were excluded (56.4 ± 17.1 vs. 67.2 ± 14.3; p = 0.0149). Overall, our findings indicate that coexisting BE in COPD patients may lead to more frequent exacerbations with a longer duration.

Abstract
BACKGROUND Bronchiectasis is frequent in smokers with COPD; however, there are only limited data on objective assessments of this process. The objective was to assess bronchovascular morphology, calculate the ratio of the diameters of bronchial lumen and adjacent artery (BA ratio), and identify those measurements able to discriminate bronchiectasis. METHODS We collected quantitative CT (QCT) measures of BA ratios, peak wall attenuation, wall thickness (WT), wall area, and wall area percent (WA%) at matched fourth through sixth airway generations in 21 ever smokers with bronchiectasis (cases) and 21 never-smoking control patients (control airways). In cases, measurements were collected at both bronchiectatic and nonbronchiectatic airways. Logistic analysis and the area under receiver operating characteristic curve (AUC) were used to assess the predictive ability of QCT measurements for bronchiectasis. RESULTS The whole-lung and fourth through sixth airway generation BA ratio, WT, and WA% were significantly greater in bronchiectasis cases than control patients. The AUCs for the BA ratio to predict bronchiectasis ranged from 0.90 (whole lung) to 0.79 (fourth-generation). AUCs for WT and WA% ranged from 0.72 to 0.75 and from 0.71 to 0.75. The artery diameters but not bronchial diameters were smaller in bronchiectatic than both nonbronchiectatic and control airways (P < .01 for both). CONCLUSIONS Smoking-related increases in the BA ratio appear to be driven by reductions in vascular caliber. QCT measures of BA ratio, WT, and WA% may be useful to objectively identify and quantify bronchiectasis in smokers. TRIAL REGISTRY ClinicalTrials.gov; No.: NCT00608764; URL: www.clinicaltrials.gov.

Abstract
Hemoptysis, or coughing of blood, oftentimes triggers anxiety and fear for patients. The etiology of hemoptysis will determine the clinical course, which includes watchful waiting or intensive care admission. Any amount of hemoptysis that compromises the patient's respiratory status is considered massive hemoptysis and should be considered a medical emergency. In this article, we review introduction, definition, bronchial circulation anatomy, etiology, and management of massive hemoptysis.

Abstract
Gram-negative organisms comprise a large portion of the pathogens responsible for lower respiratory tract infections, especially those that are nosocomially acquired, and the rate of antibiotic resistance among these organisms continues to rise. Systemically administered antibiotics used to treat these infections often have poor penetration into the lung parenchyma and narrow therapeutic windows between efficacy and toxicity. The use of inhaled antibiotics allows for maximization of target site concentrations and optimization of pharmacokinetic/pharmacodynamic indices while minimizing systemic exposure and toxicity. This review is a comprehensive discussion of formulation and drug delivery aspects, in vitro and microbiological considerations, pharmacokinetics, and clinical outcomes with inhaled antibiotics as they apply to disease states other than cystic fibrosis. In reviewing the literature surrounding the use of inhaled antibiotics, we also highlight the complexities related to this route of administration and the shortcomings in the available evidence. The lack of novel anti-Gram-negative antibiotics in the developmental pipeline will encourage the innovative use of our existing agents, and the inhaled route is one that deserves to be further studied and adopted in the clinical arena.

Abstract
BACKGROUND AND OBJECTIVES Non-Cystic Fibrosis (CF) bronchiectasis is common in Greece but little attention has been paid to the investigation of its aetiology, clinical, radiological, microbiological and lung function profile. METHODS We prospectively evaluated patients with non-CF bronchiectasis confirmed by high resolution computed tomography (HRCT) of the chest. Aetiology, clinical data, radiology score, microbiological profile and lung function were investigated. RESULTS We evaluated 277 patients (170 women) with bronchiectasis (mean age: 60.5 ± 16 years), 64% of them being non-smokers. Post-infectious (25.2%) and past tuberculosis (TB) (22.3%) were the most commonly identified underlying conditions, while no cause was found in 34% of the patients. The main symptoms were cough (82%), mucopurulent sputum (80%), dyspnea (60%) and haemoptysis (37%). Mean duration of symptoms was 9.7 (SD 10.7) years. Infectious exacerbations were observed in 67.5% of the patients with a mean frequency of 2.3 (SD 1.4) per year. The most frequent lung function pattern was the obstructive (43.1%) while 38% of the patients had normal spirometry. Pseudomonas aeruginosa was the most common pathogen yielded in sputum cultures (43%) followed by Haemophilus influenzae (12.6%). Patients with P. aeruginosa had a more long-standing disease and worse lung function. Radiological severity of the disease was mainly related to impaired lung function, P. aeruginosa isolation in sputum and frequent exacerbations. CONCLUSION Data indicate that in Greece, "past" tuberculosis remains an important cause of bronchiectasis. P. aeruginosa was the predominant pathogen in the airways, associated with disease severity, while the most common lung function impairment was obstruction.

Abstract
Chronic lung disease (CLD) in children represents a heterogeneous group of many clinico-pathological entities with risk of adverse impact of chronic or intermittent hypoxia. So far, few researchers have investigated the cognitive function in these children, and the role of auditory P300 in the assessment of their cognitive function has not been investigated yet. This study was designed to assess the cognitive functions among schoolchildren with different chronic pulmonary diseases using both auditory P300 and Stanford-Binet test. This cross-sectional study included 40 school-aged children who were suffering from chronic chest troubles other than asthma and 30 healthy children of similar age, gender and socioeconomic state as a control group. All subjects were evaluated through clinical examination, radiological evaluation and spirometry. Audiological evaluation included (basic otological examination, pure-tone, speech audiometry and immittancemetry). Cognitive function was assessed by auditory P300 and psychological evaluation using Stanford-Binet test (4th edition). Children with chronic lung diseases had significantly lower anthropometric measures compared to healthy controls. They had statistically significant lower IQ scores and delayed P300 latencies denoting lower cognitive abilities. Cognitive dysfunction correlated to severity of disease. P300 latencies were prolonged among hypoxic patients. Cognitive deficits in children with different chronic lung diseases were best detected using both Stanford-Binet test and auditory P300. P300 is an easy objective tool. P300 is affected early with hypoxia and could alarm subtle cognitive dysfunction.

Abstract
BACKGROUND AND OBJECTIVE Non-cystic fibrosis (CF) bronchiectasis is a chronic airway inflammatory disease, exhibiting a diverse array of clinical courses. The purpose of this study was to determine the factors that predict radiologic progression of non-CF bronchiectasis during a long-term follow-up. METHODS We reviewed the electronic medical records that included pulmonary function test data from non-CF bronchiectasis patients, who were older than 18 years of age with a follow-up of computerized tomography for more than 5 years. The original Bhalla score was used to determine the radiologic severity of non-CF bronchiectasis. RESULTS A total of 155 patients (mean age, 59.6 years; male, 45.2%) were included for the final analysis. The mean follow up time was 7.11 ± 1.42 (5-10) years. The baseline Bhalla score was 9.52 ± 3.14 (4-19), and the change of Bhalla score was 0.55 ± 1.14 (-2 to 5). The Bhalla score was increased in 56 patients (36.1%) but not in 99 patients (63.9%). The Bhalla score change was significantly associated with the age at diagnosis (p = 0.037), body mass index (BMI, p = 0.012), chronic infection of Pseudomonas aeruginosa (p = 0.005) or isolation of nontuberculous mycobacterium (p = 0.042) in respiratory specimens. In a multivariate analysis, BMI and isolation of P. aeruginosa were significantly related with the Bhalla score change. CONCLUSION The radiologic progression of non-CF bronchiectasis was associated with lower BMI and isolation of P. aeruginosa in respiratory specimens.

Abstract
Non-cystic fibrosis bronchiectasis (NCFBr) is a major cause of morbidity due to frequent infectious exacerbations. We analyzed the influence of patient age and bronchiectasis location on the bacterial profile of patients with NCFBr. This retrospective cohort study included 339 subjects diagnosed with an infectious exacerbation of NCFBr during the 9-year period between January 2006 and December 2014. Bronchoalveolar lavage (BAL) cultures and high-resolution computed tomography scans (HRCT) were utilized to characterize the location of the bronchiectasis and bacteriologic pathogenic profile. In univariate logistic regression, the frequency of Haemophilus influenzae was higher in patients aged ≤64 years (OR = 0.969, p < 0.0001, 95 % CI 0.954-0.983), whereas the frequency of Pseudomonas aeruginosa (OR = 1.027, p = 0.008, 95 % CI 1.007-1.048) and Enterobacteriaceae (OR = 1.039, p = 0.01, 95 % CI 1.009-1.069) were significantly higher in patients aged >64 years. The lobar distribution of bronchiectasis in the subjects was 25.9 % in the right middle lobe (RML), 20.7 % in the right lower lobe (RLL), 20.4 % in the left lower lobe (LLL), 13.8 % in the lingula, 13 % in the right upper lobe (RUL), and 6.2 % in the left upper lobe (LUL). In the lower lobes, H. influenzae was the dominant species isolated, whereas in the RUL it was P. aeruginosa and in the LUL it was non- tuberculous mycobacterium (NTM). H. influenzae was more prevalent in younger patients, whereas P. aeruginosa, Enterobacteriaceae and NTM predominated in older patients. Different pathogens were associated with different lobar distributions. The RML, RLL and LLL showed a greater tendency to develop bronchiectasis than other lobes.

Abstract
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.

Abstract
A chronic 'productive' or 'wet' cough is a common presenting complaint for patients attending the adult respiratory clinic. Most reviews and guidelines suggest that the causes of a productive cough are the same as those of a non-productive cough and as such the same diagnostic pathway should be followed. We suggest a different diagnostic approach for patients with a productive cough, focussing on the conditions that are the most likely causes of this problem. This review is intended to briefly summarise the epidemiology, clinical features, pathophysiology and treatment of a number of conditions which are often associated with chronic productive cough to aid decision making when encountering a patient with this often distressing symptom. The conditions discussed include bronchiectasis, chronic bronchitis, asthma, eosinophilic bronchitis and immunodeficiency. We also propose an adult version of the paediatric diagnosis of protracted bacterial bronchitis (PBB) in patients with idiopathic chronic productive cough who appear to respond well to low dose macrolide therapy.

Abstract
Bronchiectasis is permanent irreversible dilatation of the airways and occurs in a variety of pathologic processes. Recurrent infection and inflammation and the resulting chemical and cellular cascade lead to permanent architectural changes in the airways. Bronchiectasis can confer substantial potential morbidity, usually secondary to recurrent infection. In severe cases of bronchiectasis, massive hemoptysis can lead to death. Thin-section computed tomography is the most sensitive imaging modality for the detection of bronchiectasis; findings include bronchial diameter exceeding that of the adjacent pulmonary artery and lack of normal tapering of terminal bronchioles as they course toward the lung periphery. The authors will review various causes of bronchiectasis, including common causes, such as recurrent infection or aspiration, and uncommon causes, such as congenital immunodeficiencies and disorders of cartilage development. The authors will also present an approach emphasizing the distribution (apical versus basal and central versus peripheral) and concomitant findings, such as nodules, cavities, and/or lymphadenopathy, that can assist in narrowing the differential diagnosis. Although an adequate understanding of these underlying causes in conjunction with their specific imaging appearances will allow radiologists to more confidently determine the process causing this common radiologic finding, clinical history and patient demographic characteristics play an integral role in determining a pertinent and concise differential diagnosis.

Abstract
INTRODUCTION Non-cystic fibrosis bronchiectasis (NCFB) is a multidimensional disease, and no single isolated parameter is proved to have sufficient power for any overall determination of its severity and prognosis. OBJECTIVE To compare the results of the assessment of the NCFB severity with respect to its prognosis in the same patients by two different validated scores, i.e. the FACED score and the Bronchiectasis Severity Index (BSI). METHODS An observational study including 37 patients with NCFB (16 males and 21 female aged 46 to 76 years) was performed. All patients underwent evaluation of the variables incorporated in the FACED score (FEV1 % predicted, age, chronic colonization by Pseudomaonas aeruginosa, radiological extent of the disease, and dyspnea) and in the BSI (age, body mass index, FEV1 % predicted, hospitalization and exacerbations in previous year, dyspnea, chronic colonization by Pseudomaonas aeruginosa and other microrganisms, and radiological extent of the disease). RESULTS According to the value of the derived overall FACED score we found 17 patients (45.9%) with mild bronchiectasis, 14 patients (37.8%) with moderate bronchiectasis and 6 patients (16.2%) with severe bronchiectasis. The mean derived FACED score was 3.4 ± 1.3. In addition, according to the value of the derived overall BSI score, the frequency of patients with low, intermediate and high BSI score was 16 patients (43,2%), 14 patients (37.8%) and 7 patients (18.9%), respectively. The mean derived BSI score was 6.4 ± 2.5. CONCLUSION We found similar results by the assessment of the NCFB severity in regard to its prognosis by both the FACED score and the BSI. Further studies determining how these scores may impact clinical practice are needed.

Abstract
Diffuse cystic lung diseases are uncommon but can present a diagnostic challenge because increasing number of diseases have been associated with this presentation. Cyst in the lung is defined as a round parenchymal lucency with a well-defined thin wall (< 2 mm thickness). Focal or multifocal cystic lesions include blebs, bullae, pneumatoceles, congenital cystic lesions, traumatic lesions, and several infectious processes such as coccidioidomycosis, Pneumocystis jiroveci pneumonia, and hydatid disease. "Diffuse" distribution in the lung implies involvement of all lobes. Diffuse lung involvement with cystic lesions can be seen in pulmonary lymphangioleiomyomatosis, pulmonary Langerhans' cell histiocytosis, lymphoid interstitial pneumonia, Birt-Hogg-Dubé syndrome, amyloidosis, light chain deposition disease, honeycomb lung associated with advanced fibrosis, and several other rare causes including metastatic disease. High-resolution computed tomography of the chest helps define morphologic features of the lung lesions as well as their distribution and associated features such as intrathoracic lymphadenopathy. Correlating the tempo of the disease process and clinical context with chest imaging findings serve as important clues to defining the underlying nature of the cystic lung disease and guide diagnostic evaluation as well as management.

Abstract
Bronchiectasis is an irreversible dilatation of the bronchi resulting from chronic airway inflammation. In people, computed tomography (CT) has been described as the noninvasive gold standard for diagnosing bronchiectasis. In dogs, normal CT bronchoarterial ratios have been described as <2.0. The purpose of this retrospective study was to describe quantitative and qualitative CT characteristics of bronchiectasis in a cohort of dogs with confirmed disease. Inclusion criteria for the study were thoracic radiography, thoracic CT, and a diagnosis of bronchiectasis based on bronchoscopy and/or histopathology. For each included dog, a single observer measured CT bronchoarterial ratios at 6 lobar locations. Qualitative thoracic radiography and CT characteristics were recorded by consensus opinion of two board-certified veterinary radiologists. Twelve dogs met inclusion criteria. The mean bronchoarterial ratio from 28 bronchiectatic lung lobes was 2.71 ± 0.80 (range 1.4 to 4.33), and 23/28 measurements were >2.0. Averaged bronchoarterial ratios from bronchiectatic lung lobes were significantly larger (P < 0.01) than averaged ratios from nonbronchiectatic lung lobes. Qualitative CT characteristics of bronchiectasis included lack of peripheral airway tapering (12/12), lobar consolidation (11/12), bronchial wall thickening (7/12), and bronchial lumen occlusion (4/12). Radiographs detected lack of airway tapering in 7/12 dogs. In conclusion, the most common CT characteristics of bronchiectasis were dilatation, a lack of peripheral airway tapering, and lobar consolidation. Lack of peripheral airway tapering was not visible in thoracic radiographs for some dogs. For some affected dogs, bronchoarterial ratios were less than published normal values.

Abstract
Background Bronchiectasis is a common disease and a major cause of respiratory morbidity. Chest pain has been described as occurring in the context of bronchiectasis but has not been well characterized. This study was performed to describe the characteristics of chest pain in adult bronchiectasis and to define the relationship of this pain to exacerbations. Subjects and methods We performed a prospective study of 178 patients who were followed-up for 8 years. Subjects were reviewed on a yearly basis and assessed for the presence of chest pain. Subjects who had chest pain at the time of clinical review by the investigators were included in this study. Forty-four patients (25%) described respiratory chest pain at the time of assessment; in the majority of cases 39/44 (89%), this occurred with an exacerbation and two distinct types of chest pain could be described: pleuritic (n = 4) and non-pleuritic (n = 37), with two subjects describing both forms. The non-pleuritic chest pain occurred most commonly over both lower lobes and was mild to moderate in severity. The pain subsided as patients recovered. Conclusion Non-pleuritic chest pain occurs in subjects with bronchiectasis generally in association with exacerbations.

Abstract
High-resolution computed tomography (CT) is the preferred noninvasive tool for diagnosing bronchiectasis in people. A criterion for evaluating dilation of the bronchus is the bronchial lumen to pulmonary artery diameter (bronchoarterial ratio [BA ratio]). A ratio of > 1.0 in humans or > 2.0 in dogs has been suggested as a threshold for identifying bronchiectasis. The purpose of this study was to establish the BA ratio in normal cats. Fourteen specific pathogen-free cats were selected for analysis of thoracic CT images. The BA ratios of the lobar bronchi of the left cranial (cranial and caudal parts), right cranial, right middle, left caudal, and right caudal lung lobes were measured. The mean of the mean BA ratio of all lung lobes was 0.71 +/- 0.05. Individual BA ratios ranged from 0.5 to 1.11. Comparing individual lobes for each cat, there was no significant difference (P = 0.145) in mean BA ratio between lung lobes. A mean BA ratio for these normal cats was 0.71 +/- 0.1, which suggests an upper cut-off normal value > 0.91 (mean +/- 2 standard deviations) between normal and abnormal cats.

Abstract
BACKGROUND The purpose of this study was to demonstrate our surgical experience for focal bronchiectasis in the setting of modern diagnostic modalities and state-of-the-art medical treatment in a developed country. METHODS Thirty-one patients undergoing 33 lung resections for the treatment of focal bronchiectasis from 1991 to 2009 were reviewed. The mean age was 54 years. Twenty-nine patients (94%) were female; 21 patients (68%) had nontuberculous mycobacterial infection; and 22 patients (71%) received preoperative multiple-drug regimens containing clarithromycin. Five patients (16%) were in an immunocompromised status. All were diagnosed by chest computed tomography scan, and either the right middle lobe or left lingula were involved in 29 (94%). The curve for relapse-free interval was estimated by Kaplan-Meier methods. The factors that affected this curve were examined using Cox's regression analysis. RESULTS Operative morbidity and mortality were 18% and 0%, respectively. All patients became asymptomatic postoperatively. During the median follow-up of 48 months (11 to 216), 8 patients (26%) experienced recurrence, and the mean relapse-free interval was 34 months (3 to 216). By univariate analysis, an immunocompromised status (p=0.017), Pseudomonas aeruginosa infection (p=0.040), the preoperative extent of bronchiectatic lesion (p=0.013), and the extent of residual bronchiectasis after surgery (p=0.003) were significantly associated with the shorter relapse-free interval. By multivariate analysis, an immunocompromised status (p=0.039), Pseudomonas aeruginosa infection (p=0.033), and the extent of residual bronchiectasis (p=0.009) were independent and significant factors. CONCLUSIONS Complete resection of bronchiectasis while the disease is localized and is free from Pseudomonas aeruginosa infection is the key for a success. Also, immunocompromised status was suggested to be a risk factor.

Abstract
Bronchiectasis may result from various causes. Recognition of these underlying causes may lead to specific management. Focal bronchiectasis are related to luminal blockage or extrinsic narrowing. The causative factors of diffuse bronchiectasis may be suggested by the predominant distribution of the disease and associated extrapulmonary manifestations. Primary immunodeficiencies cystic fibrosis, allergic bronchopulmonary aspergillosis, chronic Mycobacterium avium complex infection, and systemic diseases have to be looked for, even in patients with knowledge of a childhood respiratory infection.

Abstract
BACKGROUND: Bronchiectasis has been defined as the abnormal and permanent dilation of the bronchi. It is still an important problem in many developing countries. AIM: The aim of this study was to identify the chacteristics and underlying etiology of children followed with the diagnosis of noncystic fibrosis bronchiectasis. MATERIALS AND METHODS: Children with bronchiectasis confirmed with high-resolution computed tomography were enrolled into the study. The data of the patients, including symptoms of the disease, age at the onset of symptoms, findings of physical examination, labrotory investigations performed in order to identify the etiology of bronchiectasis, etiology of bronchiectasis if found, radiologic findings and treatment modalities were noted. RESULTS: Sixty-six children between 1 and 17 years were included in the study retrospectively. Forty-four of them were males (66.7%) and 22 (33.3%) were females. The most common presenting symptoms were cough (100%) and sputum expectoration (50%). An underlying etiology was identified in 44 (66.7%) of the study subjects. The four most common underlying causes were found as infections (21.2%), asthma (16.7%), aspiration syndromes and/or gastroesophageal reflux disease (9.1%) and immunodeficiency syndromes (7.6%), respectively. CONCLUSION: Identifying an underlying etiology will have a significant effect on the management of noncystic fibrosis bronchiectasis. Defining the cause of bronchiectasis may also decrease its incidence, progression and complications.

Abstract
OBJECTIVE To provide an overview of pediatric cough, with specific emphasis on various causes, to aid in diagnosis and treatment. DATA SOURCES Relevant articles and references published between January 1, 1961, and May 1, 2009, were found through a PubMed search using the following keywords: pediatric cough and cough in children. STUDY SELECTION All key relevant articles and textbook sections were reviewed, and the most relevant were selected for inclusion in this review. RESULTS Although asthma, gastroesophageal reflux disease, and postnasal drip can be causes of cough in children, it is important to think of other potential causes, such as bronchitis, postviral cough, and foreign-body inhalation. Testing and treatment for cough will vary, depending on the presentation and diagnosis. Just as in adults, in children, the cause of cough can be multifactorial. CONCLUSIONS Pediatric cough is commonly encountered by primary care physicians and allergists. Physicians should be aware of the various potential causes of cough in children to properly determine the cause so that testing and treatment can proceed appropriately.

Abstract
Advances in computed tomography (CT) scanner technology have made isotropic volumetric, multiplanar high-resolution lung imaging possible in a single breath-hold, a significant advance over the incremental high-resolution CT (HRCT) technique in which noncontiguous images sampled the lung, but lacked anatomic continuity. HRCT of the lungs is an established imaging technique for the diagnosis and management of interstitial lung disease, emphysema, and small airway disease, providing a noninvasive detailed evaluation of the lung parenchyma, and providing information about the lungs as a whole and focally. In addition to having a high degree of specificity for diagnosing conditions such as emphysema, sarcoidosis, usual interstitial pneumonitis, Langerhans cell histiocytosis, and small airway disease, there is a growing body of medical evidence to support the use of HRCT findings or diagnosis to predict patient prognosis. In this article, we review the technique, advantages, and clinical applications of the current HRCT technique.

Abstract
Chronic obstructive pulmonary disease (COPD) is a pathological pulmonary condition characterized by expiratory airflow obstruction due to emphysematous destruction of the lung parenchyma and small airways remodeling. Although spirometry is a very useful diagnostic tool for screening large groups of smokers, it cannot readily differentiate the etiologies of COPD and thus has limited utility in characterizing subjects for clinical and investigational purposes. There has been a longstanding interest in thoracic imaging and its role in the in vivo characterization of smoking-related lung disease. Research in this area has spanned readily available modalities such as chest -ray and computed tomography to more advanced imaging techniques such as optical coherence tomography (OCT) and magnetic resonance imaging (MRI). Although the chest x-ray is almost universally available, it lacks sensitivity in detecting both airway disease and mild emphysema and is not generally amenable to objective analysis. Computed tomography has become the standard modality to objectively visualize lung disease. It can provide useful measures of the presence and extent of emphysema, airway disease, and, more recently, pulmonary vascular disease for clinical correlation. It does, however, face limitations in standardization across brands and generations of scanners, and the ionizing radiation associated with image acquisition is of concern to both patients and health care providers. Newer techniques such as OCT and MRI offer exciting in vivo insights into lung structure and function that were previously available only in necropsy specimens and physiology laboratories. Given the more limited availability of these techniques, they will be viewed here as adjuncts to computed tomographic imaging.
