Exposure to secondhand smoke from burning tobacco products causes premature death and disease, including coronary heart disease, stroke, and lung cancer among nonsmoking adults and sudden infant death syndrome, acute respiratory infections, middle ear disease, exacerbated asthma, respiratory symptoms, and decreased lung function in children (1,2). The U.S. Surgeon General has concluded that there is no risk-free level of exposure to secondhand smoke (1). Previous CDC reports on airport smoke-free policies found that most large-hub airports in the United States prohibit smoking (3); however, the extent of smoke-free policies at airports globally has not been assessed...

Background: Occupational asthma (OA) accounts for one in six cases of new-onset adult asthma. Despite this it remains under-recognized in the UK. Delayed and missed diagnoses of OA lead to poor health outcomes for workers at significant cost to the UK economy. The burden of occupational aetiology on hospital admissions with asthma is not known. Aims: To measure how frequently medical professionals consider occupational aetiology in patients presenting to secondary care with acute asthma symptoms...

BACKGROUND: Many epidemiological studies on the health effects of air pollutants have been carried out in regions with major sources such as factories and automobiles. However, the health effects of air pollutants in regions without major sources remain unclear. This study investigated the acute effects of ambient air pollution on pulmonary function among healthy students in an isolated island without major artificial sources of air pollutants. METHODS: A panel study was conducted of 43 healthy subjects who attended a school in an isolated island in the Seto Inland Sea, Japan...

Currently, >20 million people in the United States have asthma, and approximately 15 million adults have been diagnosed with COPD, with approximately the same number not yet having been diagnosed with this condition. Moreover, the overall burden of respiratory diseases is still increasing, in part due to environmental factors, such as air pollution. At the same time, the number of patients requiring hospitalization as well as the number of individuals admitted to ICUs from emergency departments has been on the rise over the last decade...

Endobronchial Tuberculosis is hazardous in causing circumferential narrowing of tracheobronchial tree despite the eradication of tubercle bacilli in the initial insult from Pulmonary Tuberculosis. They may present as treatment resistant bronchial asthma and pose challenge to airway management in the acute setting. We present a 25 year-old lady who was newly diagnosed bronchial asthma with a past history of Pulmonary Tuberculosis that had completed treatment. She presented with sudden onset of difficulty breathing associated with noisy breathing for 3 days and hoarseness of voice for 6 months...

Rhinovirus (RV) is one of the most frequent causative agent of acute respiratory tract infections in the world. The virus may cause a mild cold, as well as more serious clinical symptoms in patients with immune system deficiency or comorbidities. Rhinoviruses have been identified by molecular methods under three types: RV-A, RV-B and RV-C. In most of the cases, it was reported that RV-A and RV-C were related with lower respiratory tract infections and asthma exacerbations, while RV-B was rarely reported in lower respiratory tract infections...

BACKGROUND AND AIMS: Inhaled corticosteroids (ICSs) are crucial anti-inflammatory medications for chronic airway diseases. Studies investigating the relationship between ICSs and fractures in Asian populations are scant. We investigated whether ICSs increased the risk of low-energy fractures in patients with chronic airway diseases. METHODS: We used the Longitudinal Health Insurance Database to select patients aged 20 years and older with chronic airway diseases (asthma and COPD) between 2000 and 2011 as the base cohort...

Background: Asthma caused substantial economic and health care burden and is susceptible to air pollution. Particularly, when it comes to elder asthma patient (older than 65), the phenomenon is more significant. The aim of this study is to investigate the Markov-based acute effects of air pollution on elder asthma hospitalizations, in forms of transition probabilities. Methods: A retrospective, population-based study design was used to assess temporal patterns in hospitalizations for asthma in a region of Sichuan province, China...

BACKGROUND: Acute asthma exacerbations (AAE) account for many Pediatric Emergency Department (PED) visits. Chest radiography (CXR) is often performed in these patients to identify practice-changing findings such as pneumonia (PNA). Limited knowledge exists to balance the cost and radiation dose of CXR with expected yield of clinically meaningful information. OBJECTIVE: To determine in children with AAE with CXR, whether patient characteristics are associated with radiographic PNA; and significant practice change by initiation of antibiotic...

BACKGROUND: T-lymphocytes express not only the cell membrane calcium ORAI1 but also voltage-dependent Cav1 channels. In excitable cells, these channels are composed of the ion forming pore α1 and auxiliary subunits (β and α2δ) needed for proper trafficking and activation of the channel. We previously disclosed the role of Cav1.2 α1 in mouse and human Th2- but not Th1-cell functions and showed that knocking-down Cav1 α1 prevents experimental asthma OBJECTIVE: We investigated the role of β and α2δ auxiliary subunits on Cav1 α1 function in Th2 lymphocytes and on the development of acute allergic airway inflammation...

BACKGROUND: Lower respiratory diseases are the most frequent causes of hospital admission in children worldwide, particularly in developing countries. Daily levels of air pollution are associated with lower respiratory diseases, as documented in many time-series studies. However, investigations in low-and-middle-income countries, such as Vietnam, remain sparse. OBJECTIVE: This study investigated the short-term association of ambient air pollution with daily counts of hospital admissions due to pneumonia, bronchitis and asthma among children aged 0-17 in Hanoi, Vietnam...

Because Th17-polarized airway inflammation correlates with poor control in bronchial asthma and is a feature of numerous other difficult-to-treat inflammatory lung diseases, new therapeutic approaches for this type of airway inflammation are necessary. We assessed different licensed anti-inflammatory agents with known or expected efficacy against Th17-polarization in mouse models of Th17-dependent airway inflammation. Upon intravenous transfer of in vitro derived Th17 cells and intranasal challenge with the corresponding antigen, we established acute and chronic murine models of Th17-polarised airway inflammation...

BACKGROUND: Infections by rhinovirus (RV) species A and C are the most common causes of exacerbations of asthma and a major cause of exacerbations of other acute and chronic respiratory diseases. Infections by both species are prevalent in pre-school and school-aged children and, particularly for RV-C, can cause severe symptoms and a need for hospitalization. While associations between RV infection and asthma are well established, the adaptive immune-mechanisms by which RV infections influence asthma exacerbations are yet to be defined...

Exposure to pollutants, such as ozone, exacerbates airway inflammation and hyperresponsiveness (AHR). TNF-stimulated gene 6 (TSG-6) is required to transfer inter-α-inhibitor heavy chains (HC) to hyaluronan (HA), facilitating HA receptors binding. TSG-6 is necessary for AHR in allergic asthma, because it facilitates the development of a pathological HA-HC matrix. However, the role of TSG-6 in acute airway inflammation is not well understood. Here, we hypothesized that TSG-6 is essential for the development of HA- and ozone-induced AHR...
