Leukotriene B4 as an inflammatory mediator is an important biomarker for different respiratory diseases like asthma, chronic obstructive pulmonary disease or cystic lung fibrosis. Therefore the detection of LTB4 is helpful in the diagnosis of these pulmonary diseases. However, until now its determination in exhaled breath condensates suffers from problems of accuracy. Reasons for that could be improper sample collection and preparation methods of condensates and the lack of consistently assay specificity and reproducibility of the used immunoassay detection system...

Chlorine is a pulmonary toxicant to which humans can be exposed through accidents or intentional releases. Acute effects of chlorine inhalation in humans and animal models have been well characterized, but less is known about persistent effects of acute, high-level chlorine exposures. In particular, animal models that reproduce the long-term effects suggested to occur in humans are lacking. Here, we report the development of a rabbit model in which both acute and persistent effects of chlorine inhalation can be assessed...

BACKGROUND: Malnutrition is common among congenital diaphragmatic hernia (CDH) survivors and may result from elevated respiratory effort. We evaluated body mass index (BMI), measured resting energy expenditure (mREE) and pulmonary function test (PFT) results in children and adolescents with CDH to determine if there is a correlation. METHODS: With ethics approval (REB# 1000035323), anthropometrics, indirect calorimetry (IC) results and PFTs were collected from patients 5-17years of age during CDH clinic visits between 2000 and 2016...

The past decade has seen significant advances in understanding of the pathogenesis and progression of lung disease in cystic fibrosis. Pulmonary inflammation, infection and structural lung damage manifest very early in life and is prevalent among preschool children and infants, often in the absence of symptoms or signs. Early childhood represents a pivotal period amenable to intervention strategies that could delay or prevent the onset of lung damage and alter the longer term clinical trajectory for individuals with CF...

Airway remodeling is resultant of a complex multi-cellular response associated with a progressive decline of pulmonary function in patients with chronic airway disease. Here, repeated infections with respiratory viruses are linked with airway remodeling through largely unknown mechanisms. Although acute activation of the Toll like receptor (TLR)3 pathway by extracellular poly(I:C) induces innate signaling through the NFkB transcription factor in human small airway epithelial cells (hSAECs), prolonged (repetitive or tonic) poly(I:C) stimulation produces chronic stress fiber formation, mesenchymal transition and activation of a fibrotic program...

BACKGROUND: Doppler images of pulmonary vessels in pulmonary diseases associated with subpleural consolidations have been described. Color Doppler easily identifies such vessels within consolidations while spectral Doppler analysis allows the differentiation between pulmonary and bronchial arteries. Thus, Doppler helps in diagnosing the nature of consolidations. To our knowledge, Doppler analysis of pulmonary vessels within anesthesia-induced atelectasis has never been described before...

Epiphrenic oesophageal diverticula are rare and often asymptomatic. In this case report a 58-year-old woman was diagnosed with an epiphrenic oesophageal diverticulum, which developed an oesophagobronchial fistula leading to a pulmonary abscess in the right lower lobe, septicaemia and acute respiratory failure. The patient underwent right lower lobectomy and the diverticulum was stapled off the oesophagus. The post-operative course was uneventful. This complication is only rarely described previously.

Alternaria alternata is an allergenic fungus and known to cause an upper respiratory tract infection and asthma in humans with compromised immunity. Although A. alternata's effect on airway epithelial cells has previously been examined, the potential role of A. alternata on lung fibroblast viability is not understood. Since lung fibroblasts derived from patients with idiopathic pulmonary fibrosis (IPF) display a distinct phenotype that is resistant to stress and cell death inducing conditions, the investigation of the role of Alternaria on pathological IPF fibroblasts provides a better understanding of the fibrotic process induced by an allergenic fungus...

Transarterial chemoembolization (TACE) is an effective palliative intervention that is widely accepted for the management of hepatocellular carcinoma (HCC). Post-TACE pulmonary complications resulting in acute lung injury (ALI) or acute respiratory distress syndrome (ARDS) are rare events. Pulmonary complications after TACE are thought to be related to chemical injury subsequent to the migration of the infused ethiodized oil or chemotherapeutic agent to the lung vasculature, facilitated by arteriovenous (AV) shunts within the hyper-vascular HCC...

The number of people practising recreational breath-hold diving is constantly growing, thereby increasing the need for knowledge of the acute and chronic effects such a sport could have on the health of participants. Breath-hold diving is potentially dangerous, mainly because of associated extreme environmental factors such as increased hydrostatic pressure, hypoxia, hypercapnia, hypothermia and strenuous exercise.In this article we focus on the effects of breath-hold diving on pulmonary function. Respiratory symptoms have been reported in almost 25% of breath-hold divers after repetitive diving sessions...

Worldwide, the number of professional and sports divers is increasing. Most of them breathe diving gases with a raised partial pressure of oxygen (PO2 ). However, if the PO2 is between 50 and 300 kPa (375-2250 mmHg) (hyperoxia), pathological pulmonary changes can develop, known as pulmonary oxygen toxicity (POT). Although in its acute phase, POT is reversible, it can ultimately lead to non-reversible pathological changes. Therefore, it is important to monitor these divers to prevent them from sustaining irreversible lesions...

In the respiratory tract, viruses and bacteria can interact on multiple levels. It is well known that respiratory viruses, particularly influenza viruses, increase the susceptibility to secondary bacterial infections. Numerous mechanisms, including compromised physical and immunological barriers, and changes in the microenvironment have hereby been shown to contribute to the development of secondary bacterial infections. In contrast, our understanding of how bacteria shape a response to subsequent viral infection is still limited...
