Archives of Pathology and Laboratory Medicine: Vol. 132, No. 7, pp. 1073-1078
Improved screening techniques for lung cancer have resulted in detection of lesions that are considered to represent precursors of invasive lung carcinomas. These lesions may cause a diagnostic dilemma particularly on small biopsy or cytology specimens. Ancillary studies are usually not helpful, and diagnosis is based on morphology alone. Recognition of these lesions is very important to prevent potential diagnostic mistakes that may result in inadequate patient management. Future molecular studies may provide clinically useful diagnostic and prognostic gene markers.
Bronchopleural and alveolopleural fistulae from surgical and nonsurgical causes present unique management issues. A myriad of strategies have been employed to diminish airflow through the fistulous tracts.

Am J Physiol Lung Cell Mol Physiol 295: L44-L53, 2008
The molecular events leading to emphysema development include generation of oxidative stress and alveolar cell apoptosis. Oxidative stress upregulates ceramides, proapoptotic signaling sphingolipids that trigger further oxidative stress and alveolar space enlargement, as shown in an experimental model of emphysema due to VEGF blockade.
Am J Physiol Lung Cell Mol Physiol 295: L79-L85, 2008
Epidemiologic and animal studies have shown that exposure to particulate matter air pollution (PM) is a risk factor for the development of atherosclerosis. Whether PM-induced lung and systemic inflammation is involved in this process is not clear.
Systemic corticosteroids are known to induce osteoporosis and increase the risk for fractures in adults and children. Inhaled corticosteroids have been shown to increase the risk for osteoporosis and fractures in adults at risk; however, long-term prospective studies of children to assess risks of multiple short courses of oral corticosteroids and chronic inhaled corticosteroids have not been performed.
Meconium aspiration is believed to cause persistent pulmonary hypertension syndrome of the newborn (PPHN) via vasoconstriction, whereas meconium has a relaxant effect on rat tracheal muscle.
The pathogenesis of congenital cystic adenomatoid malformation (CCAM) is unknown and its natural history is unpredictable. Fatty acid binding protein-7 (FABP-7) has been previously described in brain and breast development, but never before in the lung.
Very preterm neonates are at risk of hypothyroxinemia because of prematurity as well as because of neonatal disease. Hypothyroxinemia is associated with impaired developmental outcome. Preterm infants who cannot be weaned from the ventilator can be treated with dexamethasone.

Journal of Asthma, Volume 45, Issue 6 August 2008 , pages 429 - 436
Traditionally, practice guidelines have recommended a step-wise approach to treatment based on asthma severity and lung function. However, increasing evidence suggests that asthma may not be adequately controlled in many patients with moderate-to-severe disease despite aggressive therapy, and that regularly evaluating the level of asthma control achieved in individual patients may be more effective than disease severity in guiding treatment decisions.
Although parenchyma-saving resection makes it possible to preserve the lung parenchyma, most surgeons are reluctant to perform it for congenital cystic adenomatoid malformation (CCAM) because it could also result in recurrent pulmonary infection or residual lesion. This study compared the early and late postoperative outcomes according to the extent of resection in CCAM patients to determine if the extent of resection would influence the short- and long-term results.
Exercise tests are increasingly used during preoperative evaluation before lung resection. This study assessed the association between performance at the symptom-limited stair-climbing test and postoperative cardiopulmonary morbidity, mortality, and costs after major lung resections.
Primary graft dysfunction (PGD) in the immediate post-lung transplant period strongly increases the risk of chronic rejection (broncholitis obliterans syndrome). Here, we hypothesized that PGD-induced inflammation augments alloimmunity, thereby predisposing to broncholitis obliterans syndrome.
Scandinavian Journal of Infectious Diseases First Published on: 02 June 2008
It is well documented that antiphospholipid antibodies are increased in patients with HIV-1 infection and these are most commonly seen in those with Pneumocystis jirovecii pneumonia. Therefore it has been proposed that this could be the cause of its presence.

The aim of the study was to assess whether perinatal factors are associated with the risk of asthma in childhood in a register-based, nested case-control study in Finland. All children born between January 1, 1996, and April 30, 2004, who were entitled to a special reimbursement for antiasthmatic drugs (i.e., had diagnosed asthma by 2006 and had purchased inhaled corticosteroids or montelukast at least once), were identified (n = 21,038). For each case, one matched control child was selected.
Endotracheal tube (ETT) suction is the most frequently performed invasive procedure in ventilated newborn infants and is associated with adverse effects related to negative tracheal pressure. We aimed to measure suction catheter gas flow and intratracheal pressure during ETT suction of a test lung and develop a mathematical model to predict tracheal pressure from catheter and ETT dimensions and applied pressure.

Cystic Fibrosis (CF) is an autosomal recessive disorder due to mutations in the CF transmembrane conductance regulator (CFTR) gene that lead to defective ion transport in the conducting pulmonary airways and exocrine glands.
Interpretation of the Hospital Anxiety and Depression Scale (HADS), commonly used to assess anxiety and depression in COPD patients, is unclear. Since its minimal important difference has never been established, our aim was to determine it using several approaches.
Local inflammation in airway diseases is well recognised, but less is known about the association between low-grade systemic inflammatory processes and lung function. The aim of the present study was to assess the association between inflammatory markers and lung function, taking into account polymorphisms in genes coding for inflammatory markers.
Clock genes regulate mammalian circadian rhythms, and dysfunction of clock genes can contribute to various disorders. To investigate whether obstructive sleep apnoea syndrome (OSAS) influences clock gene function, the present authors examined Period1 (Per1) mRNA expression in vitro and in vivo.
Granulocyte-macrophage colony-stimulating factor (CSF), also known as CSF2, and granulocyte CSF, also known as CSF3, are important survival and proliferation factors for neutrophils and macrophages. The objective of the present study was to determine whether single nucleotide polymorphisms (SNPs) of CSF2 and CSF3 are associated with lung function in smoking-induced chronic obstructive pulmonary disease.

The relative efficacy of various inhaled corticosteroids (ICSs) for oral corticosteroid (OCS)-sparing effect in asthma is not known. To our knowledge, no randomized controlled trial directly comparing 2 ICSs has been reported, but several randomized controlled trials have reported comparison of various ICSs with placebo.

Indacaterol is a novel once-daily inhaled {beta}2-agonist in development for the treatment of patients with asthma or chronic obstructive pulmonary disease.
Enteral tube feeding is routinely used in many cystic fibrosis centres when weight for height percentage is less than 85%, when there has been weight loss for longer than a two-month period or when there has been no weight gain for two to three months (under five years old) or for six months (over five years old).

Non-specific cough is defined as non-productive cough in the absence of identifiable respiratory disease or known aetiology. It is commonly seen in paediatric practice. These children are treated with a variety of therapies including anti-histamines. Also, anti-histamines are advocated as an empirical treatment in adults with chronic cough.
The goal was to establish whether reduced amounts of pulmonary surfactant contribute to postextubation respiratory failure in preterm infants recovering from respiratory distress syndrome.
