BACKGROUND Treatment of moderate or severe chronic obstructive pulmonary disease (COPD) with combinations of inhaled corticosteroids, long-acting beta-agonists, and long-acting anticholinergic bronchodilators is common but unstudied. OBJECTIVE To determine whether combining tiotropium with salmeterol or fluticasone-salmeterol improves clinical outcomes in(More)
Chronic obstructive pulmonary disease (COPD) is a major respiratory illness in Canada that is preventable and treatable but unfortunately remains underdiagnosed. The purpose of the present article from the Canadian Thoracic Society is to provide up-to-date information so that patients with this condition receive optimal care that is firmly based on(More)
Chronic obstructive pulmonary disease (COPD) is a common cause of disability and death in Canada. Moreover, morbidity and mortality from COPD continue to rise, and the economic burden is enormous. The main goal of the Canadian Thoracic Society (CTS) Evidence-Based Guidelines is to optimize early diagnosis, prevention and management of COPD in Canada.(More)
Lung disease is a rare complication of inflammatory bowel disease (IBD). Herein is a series of seven IBD patients who developed new, persistent and unexplained symptoms of respiratory disease, particularly chronic productive cough. Using a CT scan of the chest, a diagnosis of bronchiectasis was made in five patients, while the diagnosis of chronic(More)
BACKGROUND Several sets of Canadian guidelines for the diagnosis and management of asthma have been published over the past 15 years. Since the last revision of the 1999 Canadian Asthma Consensus Report, important new studies have highlighted the need to incorporate new information into the asthma guidelines. OBJECTIVES To review the literature on adult(More)
The clinical outcome of sarcoidosis is quite variable. Several scoring systems have been used to assess the level of disease and clinical outcome. The definition of clinical phenotypes has become an important goal as genetic studies have identified distinct genotypes associated with different clinical phenotypes. In addition, treatment strategies have been(More)
Dyspnea is a cardinal symptom of chronic obstructive pulmonary disease (COPD), and its severity and magnitude increases as the disease progresses, leading to significant disability and a negative effect on quality of life. Refractory dyspnea is a common and difficult symptom to treat in patients with advanced COPD. There are many questions concerning(More)
BACKGROUND COPD is a major cause of morbidity and mortality in the United States as well as throughout the rest of the world. An exacerbation of COPD (periodic escalations of symptoms of cough, dyspnea, and sputum production) is a major contributor to worsening lung function, impairment in quality of life, need for urgent care or hospitalization, and cost(More)
As peripheral blood monocytes (PBM) differentiate into tissue macrophages, they undergo a variety of functional changes. One such difference which has been described is an enhanced metabolism of arachidonic acid (AA) via the 5-lipoxygenase (5-LO) pathway in alveolar macrophages (AM) as compared to PBM. In order to elucidate a possible mechanism for this(More)
BACKGROUND Symptomatic disease due to nontuberculous mycobacteria (NTM) is known to occur commonly in the presence of structural lung disease, but is not described in association with asthma. METHODS This was a case-control study nested in a cohort. We identified 22 patients with difficult asthma referred to a tertiary academic referral center and(More)
