The pressure-dependent air leak after partial lung resection
Case report A 72-year-old man with a right middle lobe lung adenocarcinoma underwent lobectomy with removal of tube thoracostomy 3 days after the thoracic surgery. He presented approximately 3 weeks after surgery with increasing dyspnoea. A chest X-ray (CXR) revealed a moderately large, loculated basilar pneumothorax (figure 1A). A small bore tube thoracostomy was placed with reduction of the pneumothorax. However, a moderate-sized pneumothorax with a persistent air leak persisted for approximately 2 weeks after chest tube placement requiring ongoing hospitalisation (figure 1B). Pleural manometry was perform...

Large airways nodularity secondary to tracheobronchopathia osteochondroplastica
A 74-year-old retired librarian was referred for assessment after a full-body CT, performed to investigate a 3-month history of persistent nausea and weight loss, incidentally identified a 10 mm left lower lobe nodule alongside small volume nodularity seen throughout the trachea and proximal main bronchi (figure 1). There was no previous thoracic imaging for comparison. She had a five pack-year smoking history and reported no preceding respiratory disease or symptoms. Her medical background was otherwise unremarkable. She appeared well in clinic; physical examination, basic spirometry (FEV1 131%, FVC 133% predicted) a...

Placental transmogrification of the lung presenting as progressive symptomatic bullous emphysema
In 2015, a 63-year-old non-smoking male with a history of bullous emphysema, for which a wedge resection of the right lower lobe had been performed in 1972, presented with progressive dyspnoea on exertion and coughing. Pulmonary function tests demonstrated a moderate obstructive pattern with normal diffusion capacity (FEV1: 61%, FVC: 64%, TLco: 86%). CT of the thorax revealed localised bullous–cystic changes in the right lower lobe with displacement of the mediastinum to the contralateral side (figure 1). Due to the patient’s increasing respiratory distress, a right lower lobectomy was performed. Grossly, the s...

Histologist's original opinion compared with multidisciplinary team in determining diagnosis in interstitial lung disease
Guidelines recommend that multidisciplinary interstitial lung disease meeting (ILD MDT) decisions become the gold standard for diagnosis, replacing the histologist from this position, and identify this as requiring supportive evidence. We have compared diagnoses from lung biopsy material made by expert histologists with the subsequent consensus opinion from a properly constituted ILD MDT in 71 consecutive patients referred to a regional thoracic unit. MDT changed the original histological diagnoses in 30% (95% CI 19.3% to 41.6%) and strengthened the diagnoses from probable to confident in a further 17% (95% CI 9.1% to 27.7...

Endobronchial valves for patients with heterogeneous emphysema and without interlobar collateral ventilation: open label treatment following the BeLieVeR-HIFi study
Outcomes in early trials of bronchoscopic lung volume reduction using endobronchial valves for the treatment of patients with advanced emphysema were inconsistent. However improvements in patient selection with focus on excluding those with interlobar collateral ventilation and homogeneous emphysema resulted in significant benefits in the BeLieVeR-HIFi study compared with sham treated controls. In this manuscript we present data from the control patients in the BeLieVeR-HIFi study who went on to have open label endobronchial valve treatment after completion of the clinical trial (n=12), combined with data from those in the...

{beta}-Blockers, heart disease and COPD: current controversies and uncertainties
Treating people with cardiovascular disease and COPD causes significant clinician anxiety. β-Blockers save lives in people with heart disease, specifically postinfarction and heart failure. COPD and heart disease frequently coexist and people with both disorders have particularly high cardiovascular mortality. There are concerns about giving β-blockers to people with concomitant COPD that include reduced basal lung function, diminished effectiveness of emergency β-agonist treatments, reduced benefit of long-acting β-agonist treatment and difficulty in discriminating between asthma and COPD. β-Block...

Relieving dyspnoea by non-invasive ventilation decreases pain thresholds in amyotrophic lateral sclerosis
Conclusion Relieving dyspnoea by NIV in patients with ALS having respiratory failure is associated with decreased pressure pain thresholds. Clinical implications have yet to be determined, but this observation suggests that patients with ALS could become more susceptible to pain after the institution of NIV, hence the need for reinforced attention towards potentially painful diagnostic and therapeutic interventions.

Progress in respiratory management of bulbar complications of motor neuron disease/amyotrophic lateral sclerosis?
Loss of motor neurons in the cortex, brainstem and spinal cord is the hallmark of motor neuron disease/amyotrophic lateral sclerosis (MND/ALS), resulting in weakness of limbs, respiratory and bulbar muscles and eventually death from respiratory failure in the majority of patients. Around 20%–30% have bulbar symptoms at onset—this is less common in younger patients, but affects more than 40% of those over 70 years.1 Virtually all patients will develop bulbar symptoms with disease progression. Symptoms consist of dysarthria, dysphagia, difficulties clearing oropharyngeal secretions, impaired cough, choking, ...

Bifunctional peptide-based opioid agonist/nociceptin antagonist ligand for dual treatment of nociceptive and neuropathic pain
Abstract: Drugs able to treat both nociceptive and neuropathic pain effectively without major side effects are lacking. We developed a bifunctional peptide-based hybrid (KGNOP1) that structurally combines a mu-opioid receptor agonist (KGOP1) with antinociceptive activity and a weak nociceptin receptor antagonist (KGNOP3) with anti-neuropathic pain activity. We investigated KGNOP1-related behavioral effects after intravenous administration in rats by assessing thermal nociception, cold hyperalgesia in a model of neuropathic pain induced by chronic constriction injury of the sciatic nerve, and plethysmography parameters incl...

Effects of different mycotoxins on humans, cell genome and their involvement in cancer (Review).
Authors: Ahmed Adam MA, Tabana YM, Musa KB, Sandai DA Abstract The chemical nature of most of the mycotoxins makes them highly liposoluble compounds that can be absorbed from the site of exposure such as from the gastrointestinal and respiratory tract to the blood stream where it can be dissimilated throughout the body and reach different organs such as the liver and kidneys. Mycotoxins have a strong tendency and ability to penetrate the human and animal cells and reach the cellular genome where it causes a major mutagenic change in the nucleotide sequence which leads to strong and permanent defects in the genome. ...

Chest Computed Tomography Signs in Pulmonary Disease - A Pictorial Review.
Abstract Computed tomography (CT) of the chest is one of the most important imaging modalities available to a pulmonologist. The advent of high-resolution CT of the chest has led to its increasing use. While chest radiographs are still useful as an initial test, their utility is limited in the diagnosis of lung diseases which depend on higher resolution images such as interstitial lung diseases and pulmonary vascular diseases. Several metaphorical chest CT signs have been described linking abnormal imaging patterns to lung diseases. Some of these are specific to a disease, while others help narrow the differential...

Mitochondrial Complex I Activity is Conditioned by Supercomplex I-III2-IV Assembly in Brain Cells: Relevance for Parkinson's Disease.
Abstract The assembly of complex I (CI) with complexes III (CIII) and IV (CIV) of the mitochondrial respiratory chain (MRC) to configure I-III- or I-III-IV-containing supercomplexes (SCs) regulates mitochondrial energy efficiency and reactive oxygen species (mROS) production. However, whether the occurrence of SCs impacts on CI specific activity remains unknown to our knowledge. To investigate this issue, here we determined CI activity in primary neurons and astrocytes, cultured under identical antioxidants-free medium, from two mouse strains (C57Bl/6 and CBA) and Wistar rat, i.e. three rodent species with or with...

Predicting risk factors for radiation pneumonitis after stereotactic body radiation therapy for primary or metastatic lung tumors.
CONCLUSIONS: Subclinical ILD was the only significant factor for grade 2-5 RP. In addition, the cases with honeycombing had a high potential for fatality related to severe RP. Patients with subclinical ILD should be carefully monitored for the occurrence of severe RP after SBRT. Advances in knowledge: Hypofractionated stereotactic body radiotherapy (SBRT) for primary or metastatic lung tumors provides a high local control rate and safe treatment [1]. Several reports have suggested that SBRT provides high local control rates of around 90% for patients with lung tumors [1-5]. SBRT provides not only a high local control rate,...

A generalized framework unifying image registration and respiratory motion models and incorporating image reconstruction, for partial image data or full images.
Abstract Surrogate-driven respiratory motion models relate the motion of the internal anatomy to easily acquired respiratory surrogate signals, such as the motion of the skin surface. They are usually built by first using image registration to determine the motion from a number of dynamic images, and then fitting a correspondence model relating the motion to the surrogate signals. In this paper we present a generalized framework that unifies the image registration and correspondence model fitting into a single optimization. This allows the use of 'partial' imaging data, such as individual slices, projections, or k...

Age-related alterations of the CD19 complex and memory B cells in children with Down syndrome
AbstractChildren with Down syndrome (DS) have a high incidence of recurrent respiratory tract infections, leukaemia and autoimmune disorders, suggesting immune dysfunction. The present study evaluated the role of the CD19 complex and memory B cells in the pathogenesis of immunodeficiency in children with DS. The expression levels (median fluorescein intensity —MFI) of CD19, CD21 and CD81 molecules on the surface of B cells and memory B cell subsets were studied in 37 patients and 39 healthy controls. Twenty-nine of the DS group had congenital cardiac disease. The B cell count was significantly low in children with DS com...
