The airway epithelium of human and animal lungs contains highly specialized pulmonary neuroendocrine cells (PNEC), distributed as solitary cells and as innervated clusters, neuroepithelial bodies (NEB). The designation "PNEC system" stems from the expression of both neural and endocrine cell phenotypes, including the synthesis and release of amine (serotonin, 5-HT) and a variety of neuropeptides (that is, bombesin).
Allergy, Volume 62, Number 12, December 2007 , pp. 1451-1455(5)
Chronic sinusitis (CS) with asthma generally exhibits a high degree of sinus tissue eosinophilia and recurrence often occurs even after surgical therapy. However, the cause has not yet been fully clarified.
Detailed deposition patterns of inhaled wood dust in an anatomically accurate nasal cavity were investigated using computational fluid dynamics (CFD) techniques. Three wood dusts, pine dust, heavy oak dust, and light oak dust, with a particle size distribution generated by machining (Chung et al., 2000), were simulated at an inhalation flow rate of 10 L/min. It was found that the major particle deposition sites were the nasal valve region and anterior section of the middle turbinate.

The aim of the study was to describe the oral antibiotics prescribed as step-down therapy for patients hospitalized for community-acquired pneumonia (CAP).
Despite current regulations, which limit the levels of certain air pollutants, there are still a number of adverse health effects that result from exposure to these agents. Numerous epidemiological studies have noted an association between the levels of air pollution and hospital admissions for a variety of different health reasons, including a number of respiratory diseases, as well as increased morbidity and mortality associated with various respiratory conditions and diseases.
The clinical course of patients with idiopathic pulmonary fibrosis (IPF) is generally marked by a decline in pulmonary function over time. Increasingly, patients have been recognized as having an acute, and often fatal, clinical deterioration, termed an acute exacerbation of IPF (AE-IPF).
The longer the duration of symptoms of occupational asthma (OA) before diagnosis, the poorer the outcome. Physicians can play a key role in the early recognition of occupational lung diseases (OLDs), including OA. Our objective was to document and compare the practice patterns, barriers, and needs for early diagnosis of OA among pulmonologists and family physicians.
The current recommendations of 8 to 12 min for the optimal targeted duration of symptom-limited maximal cardiopulmonary exercise testing (CPET) to attain maximal oxygen consumption are based on results from healthy individuals and may not be applicable to patients with severe COPD.

The evolutionarily conserved 18-glycosyl-hydrolase family contains true chitinases and chitinase-like proteins that lack enzymatic activity. Acidic mammalian chitinase has recently been associated with animal models of asthma. The related chitinase-like protein, YKL-40 (also called human cartilage glycoprotein 39 [HCgp-39] and chitinase 3-like 1), can be readily measured in the serum. However, its relationship to asthma has not been evaluated.
We have previously shown that exposure of respiratory epithelial cells to diesel exhaust (DE) enhances susceptibility to influenza infection and increases the production of interleukin (IL)-6 and interferon (IFN)-Beta.
We measured noise intensity and perceived noisiness during continuous positive airway pressure (CPAP) performed with two interfaces (face-mask, helmet) and four delivery systems.
Gastroesophageal reflux has been suggested as an underlying cause of chronic lung disease. The aim of this study was to assess the value of pepsin and bile acids, both components of GI secretions, in the lungs of children with chronic lung diseases as possible markers for gastroesophageal reflux disease and their relation to oxidation and inflammation.

Lung damage may take place after a single exposure to an irritant gas, fume, or vapor. It is surprising that, although thousands of persons experience accidental high-level irritant exposure each year and seek medical care, a majority recover and few persons die.
Clinical Pulmonary Medicine. 14(6):366, November 2007
Empiric antibiotics are frequently used in the intensive care unit (ICU) in the absence of confirmed infections and, in these cases, prolonged use is not helpful and may be harmful.
Clinical Pulmonary Medicine. 14(6):315-320, November 2007
Occupational asthma (OA) is an important cause of adult onset asthma and may contribute particularly to severe asthma. There are two major forms of OA: (1) OA with latency that develops after sensitization to workplace antigens and (2) irritant-induced asthma that develops from direct effects of an irritant on the airway. A number of host and environmental factors will determine whether an individual develops OA.
Smoking activates and recruits inflammatory cells and proteases to the airways. Matrix metalloproteinase (MMP)-12 may be a key mediator in smoke induced emphysema. However, the influence of smoking and its cessation on airway inflammation and MMP-12 expression during COPD is still unknown.

During pressure support ventilation, ventilator inspiration ends when inspiratory flow drops to a given percentage of the peak inspiratory flow cycling-off criteria. This study evaluated the effect of two different cycling-off criteria on breathing pattern, respiratory effort, and gas exchange in patients with chronic obstructive pulmonary disease.
Noninvasive positive-pressure ventilation is a type of mechanical ventilation that does not require an artificial airway. Studies published in the 1990s that evaluated the efficacy of this technique for the treatment of diseases as chronic obstructive pulmonary disease, congestive heart failure and acute respiratory failure have generalized its use in recent years.
Pediatric Critical Care Medicine. 8(6):519-523, November 2007
Objective: 1) To alert the clinician that increasing rate and depth of breathing during treatment of acute asthma may be a manifestation of metabolic acidosis with hyperventilation rather than worsening airway obstruction; and 2) to describe the frequency of metabolic acidosis with hyperventilation in children with severe acute asthma admitted to our pediatric intensive care unit.
Dyspnea is the primary symptom limiting exercise in patients with COPD. Recent research has demonstrated that psychological factors can substantially influence the perception of dyspnea, but little is known about the modulation of perceived intensity or unpleasantness of dyspnea by attentional distraction.
This article reviews the research on the relation between indoor air pollution exposure and acute respiratory infection (ARI) in children in developing countries. ARI is a cause of death globally, causing approximately 19% of all deaths before the age of 5 years, according to a World Health Organization estimate.
It has been postulated that right ventricular (RV) function may improve after lung volume reduction surgery (LVRS) for severe emphysema due to improvement in lung elastic recoil. Improved lung elastic recoil after LVRS is hypothesized to "tether" open extraalveolar vessels, thereby leading to a decrease in pulmonary vascular resistance (PVR) and improved RV function.
Obstructive sleep apnea (OSA) is a common disorder associated with serious health consequences, increased health-care utilization, and economic burden. With greater public and medical attention to sleep disorders, the volume of referrals for sleep studies over the last decade has increased by approximately 12-fold. Despite the steep growth of infrastructure to diagnose and treat OSA, access to such services remains a sizeable problem, and demand overwhelms capacity.
The use of portable monitors (PM) devices has been demonstrated in a wide variety of investigational settings with varying results. While most devices correlate very well with in-laboratory polysomnography, some still misclassify a significant numbers of patients and have lower sensitivity.
Combining bronchodilators has been shown to be beneficial in patients with COPD. The additive effects of short-acting bronchodilators added to maintenance tiotropium therapy, however, are unknown.

Constipation with faecal impaction is a common condition, which may lead to serious potential complications. Among such complications, stercoral perforation has been rarely reported in the literature. We report a single case of 75-year-old woman, with a massive faecal impaction, which resulted in a rectum perforation, presented as a pneumoperitoneum, pneumomediastinum and subcutaneous emphysema.
The Internet Journal of Anesthesiology. 2007. Volume 14 Number 2
Anaesthesiologists are usually conservative in accepting children with URI (Upper Respiratory Tract Infection) for surgery and cases are scheduled for a later symptom free date. This is for fear of aiway hyper-reactivity and its associated complications which are a major concern to the anaesthesiologist. It is for this reason that we conducted the present study to see if children with mild URI or those diagnosed by the pediatrician as having allergic rhinitis (with out any symptoms of viral URI or LRTI) can be taken up for surgery with extra vigilance and whether LMA could serve as an appropriate substitute in minimizing the adverse respiratory events associated with URI.
American Journal of Respiratory and Critical Care Medicine Vol 176. pp. 974-982, (2007)

Cystic fibrosis is a recessive genetic disease characterized by dehydration of the airway surface liquid and impaired mucociliary clearance. As a result, individuals with the disease have difficulty clearing pathogens from the lung and experience chronic pulmonary infections and inflammation. Death is usually a result of respiratory failure. Newly introduced therapies and aggressive management of the lung disease have resulted in great improvements in length and quality of life, with the result that the median expected survival age has reached 36 years.
PEDIATRICS Vol. 120 No. 5 November 2007, pp. e1203-e1211

Sarcoidosis is an inflammatory disease of unknown etiology, most commonly affecting the lungs. Activated CD4+ T cells accumulate in the lungs of individuals with sarcoidosis and are considered to be of central importance for inflammation.
Squamous metaplasia (SM) is common in smokers and is associated with airway obstruction in chronic obstructive pulmonary disease (COPD). A major mechanism of airway obstruction in COPD is thickening of the small airway walls.
Airway dendritic cells (DCs) are key regulators of pulmonary immune responses. However, information is limited regarding the characteristics of airway DCs in human lung diseases.
Pleural effusion is a common complication of various diseases. Conventional methods are not always capable of establishing the cause of pleural effusion, so alternative tests are needed. The aim of this study was to explore means of discriminating between different pleural effusion groups, malignant, parapneumonic and tuberculous, based on the combined function of seven biological markers.
In patients with asthma and chronic obstructive pulmonary disease, the addition of long-acting
Beta2-agonists (LABA) to glucocorticosteroids (GCS) results in better control than increasing the dose of GCS alone. In smooth muscle cells and fibroblasts, one apparent underlying mechanism involves the ability of LABAs to activate the glucocorticoid receptor
(GR).
Bronchiolitis obliterans syndrome (BOS), a process of fibro-obliterative occlusion of the small airways in the transplanted lung, is the most common cause of lung transplant failure. We tested the role of cell-mediated immunity to collagen type V [col(V)] in this process. PBMC responses to col(II) and col(V) were monitored prospectively over a 7-year period.
The lungs are the most frequent sites of these infections, and in different geographic regions, tuberculosis, bacterial pneumonia and Pneumocystis jiroveci are the dominant pathogens.
Acute exacerbations are important in the clinical course of COPD, yet the underlying mechanisms are poorly understood. Systemic inflammation is now considered as an important component in the disease process. In this study we evaluated longitudinally the systemic inflammation during hospital treatment for acute exacerbation and after clinical recovery.
Right ventricular function is frequently abnormal in patients with systemic sclerosis, but whether this is related to pulmonary vascular complications of the disease is unclear.

Chronic obstructive pulmonary disease (COPD) is a common and disabling condition in adults. Information about therapeutic effectiveness and adverse effects of common treatment options and how clinical and spirometric characteristics affect outcomes is not well known but is important for clinicians caring for patients with stable COPD.
In patients with emphysema being evaluated for lung volume reduction surgery, Doppler echocardiography has been used to screen for pulmonary hypertension as an indicator of increased peri-operative risk.
To evaluate our experience with patients who presented with chronic cough and how exhaled nitric oxide predicted response to inhaled corticosteroid (ICS) therapy.
Despite the introduction of new drugs that have changed the course of pulmonary arterial hypertension (PAH), some patients are still refractory to treatment and deteriorate rapidly. Long-acting phosphodiesterase-5 inhibitors are a new class of drugs that are effective in PAH.
Obesity may contribute to the development and clinical expression of asthma. However, how obesity can influence response to asthma medications is still uncertain.
Dyspnea and exercise limitation are common in patients with idiopathic pulmonary arterial hypertension (IPAH). Recently, a reduction in inspiratory and expiratory muscle strength has been observed in IPAH.
Bronchiectasis is a heterogeneous disease in terms of its clinical and functional presentation. Some isolated parameters have been used to assess the severity of bronchiectasis or its response to treatment.
