A 43-year-old African American woman presented to the emergency department with severe dyspnea, wheeze, and cough productive of white sputum. Three years earlier, she had been given a diagnosis of asthma based on symptoms of wheeze and cough; her treatment regimen included intermittent use of albuterol.
A 61-year-old man with arthritis and an 80-pack-year smoking history presented with fever, dyspnea, and productive cough of a week’s duration that did not respond to outpatient treatment with levofloxacin.
A 6-month-old boy has a 1-week history of dry cough that worsens at night. He has been wheezing intermittently for the past month.

Prof. Dominic Fitzgerald, a pediatric respiratory and sleep physician, reviews the basics about spirometry, and explains its use in children.
Among the information of interest to primary care: Asymptomatic smokers may show signs of COPD, and what to do about it. How to treat obstructive sleep apnea as effectively as a sleep center. And things you may not know about inhalers. More »
A panel of physiological markers of respiratory function adds significantly to the predictive value of clinical prognostic factors such as forced expiratory volume and age. More »
Despite widespread concern about the use of these drugs for patients with asthma and allergies, a review of the evidence shows that (used as recommended) there is very little risk from introducing a steroid into the upper respiratory system on a fairly regular basis, even for a child. More »
Amish school children have a lower prevalence of allergies and asthma, especially if they've had plenty of exposure to cows. A study of European farm families suggests the reason. More »
As one of 17 medical organizations collaborating in the nationwide "Choosing Wisely" campaign to help doctors and patients work together to reduce unwarranted testing, the American Academy of Allergy and Immunology has made five suggested topics for discussion. Your patients with asthma and... More »
The test can improve outcomes for COPD, but a new review outlines revised standards that call for going beyond spirometry to assess the status of patients with the condition. More »
Physicians are being under-reimbursed for vaccinations nearly half the time, according to new data released by athenahealth. Most physicians are properly reimbursed for the cost of the vaccine itself, but getting paid for administration of the vaccine is another matter.
A 56-year old was seen in the ED after 4 days of hemoptysis and intermittent left chest pain. He also complained of exertional dyspnea and arthralgias. He had been treated for “pneumonia” twice during the past month. Histories were unremarkable.

AbstractObjective To determine whether there is a relation between aortic diameter and morbidity and mortality in men screened for abdominal aortic aneurysm.Design Prospective cohort study.Setting Highland and Western Isles (a large, sparsely populated area of Scotland).Participants 8146 men aged 65-74.Main outcome measures Morbidity and mortality in relation to presence of abdominal aortic aneurysm and three categories of aortic diameter (24 mm, 25-29 mm, and 30 mm).Results When screened, 414 men (
Prolonged exposure to hyperoxia in neonates can cause hyperoxic acute lung injury (HALI), which is characterized by increased pulmonary permeability and diffuse infiltration of various inflammatory cells. Disruption of the epithelial barrier may lead to altered pulmonary permeability and maintenance of barrier properties requires intact epithelial tight junctions (TJs). However, in neonatal animals, relatively little is known about how the TJ proteins are expressed in the pulmonary epithelium, including w

Over the past few years there have been an increasing number of research articles published in Thorax on respiratorytract infections (including tuberculosis) affecting children and adults. Although these articles cover a wide variety of areas, several broad themes can be discerned. These include greater interest in viral respiratory infections (partially stimulated by the recent influenza A pandemic), improved characterisation of who is at risk of community-acquired pneumonia and mycobacterial infection, research into better diagnostics and attempts to develop new or improved scoring scales for a range of respiratory infection syndromes. There have also been a limited number of articles on how to manage patients with respiratory infection, including describing the efficacy of prevention by vaccination. Overall, there has been a discernible emphasis on transferring advances in clinical science to actual clinical practice, with several papers using molecular methodologies or measuring
Community respiratory viruses are significant causes of morbidity and mortality in patients with leukemia and hematopoietic stem cell transplant (HSCT) recipients. Data on characteristics and outcomes of parainfluenza virus (PIV) infections in these patients are limited. We reviewed the records of patients with leukemia and HSCT recipients who developed PIV infections to determine the characteristics and outcomes of such infections. We identified 200 patients with PIV infections, including 80 (40%) patients with leukemia and 120 (60%) recipients of HSCT. At presentation, most patients (70%) had an upper respiratorytract infection and the remaining patients (30%) had pneumonia. Neutropenia, APACHE II score more than 15, and respiratory coinfections were independent predictors of progression to pneumonia on multivariate analysis. Overall mortality rate was 9% at 30 days after diagnosis and 17% among patients who had PIV pneumonia, with no significant difference between patients with
Cardiac and pulmonary pathophysiologies are closely interdependent, which makes the management of patients with congenital heart disease (CHD) all the more complex. Pulmonary complications of CHD can be structural due to compression causing airway malacia or atelectasis of the lung. Surgical repair of CHD can also result in structural trauma to the respiratory system, e.g., chylothorax, subglottic stenosis, or diaphragmatic paralysis. Disruption of the Starling forces in the pulmonary vascular system in certain types of CHD lead to alveolar-capillary membrane damage and pulmonary oedema. This in turn results in poorly compliant lungs with a restrictive lung function pattern that can deteriorate to cause hypoxemia. The circulation post single ventricle palliative surgery (the so called "Fontan circulation") poses a unique spectrum of pulmonary pathophysiology with restrictive lung function and a low pulmonary blood flow state that predisposes to thromboembolic complications and plastic
We retrospectively investigated incidence, morbidity, and mortality of neonatal respiratory failure (NRF) in China, with special emphasis on surfactant treated very immature infants.|NRF was defined as respiratory hypoxemia requiring mechanical ventilation and/or nasal continuous positive airway pressure for at least 24 hours.|There were 6864 cases of NRF, composing 19.7% of total admissions to 55 NICUs in 2008. Of these cases, 62.8% were preterm, and 16.4% of very low birth weight (VLBW, <1500 g). The primary diseases were respiratory distress syndrome (RDS, 43.9%), pneumonia/sepsis (21.7%), transient respiratory insufficiency (14.7%), transient tachypnea (8.1%), and meconium aspiration syndrome (7.0%). Surfactant was given to 26.8% of infants with NRF and 54.8% infants with RDS. The survival rate of surfactant-treated RDS was 79.9% compared to 71.8% in those not receiving surfactant (P < .001). This was also true in those of VLBW, 59.8% vs 52.2% (P = .035), respectively. The overall
Red blood cell (RBC) transfusion is associated with lung injury in susceptible hosts, although many cases do not meet criteria for transfusion-related acute lung injury. Patients with underlying pulmonary fibrosis can exhibit precipitous deteriorations in respiratory status of unknown etiology defined as acute exacerbations due to superimposed lung injury syndrome. It is unclear whether RBC transfusion is associated with acute exacerbation of underlying pulmonary fibrosis.|We describe a patient who underwent an uneventful elective left total hip replacement but developed anemia postoperatively. Twenty-four hours after transfusion of her fifth nonleukoreduced AS-5 RBC unit, she developed new bilateral airspace infiltrates associated with progressive hypoxemia. These RBC units were 35 to 38 days old. Despite supportive care and diuresis, the patient remained profoundly hypoxemic with infiltrates that progressed to fibrosis.|The patient had mild subclinical lower-lobe predominant
