ConclusionPneumorrachis is usually asymptomatic and is self-limiting. It is a radiological diagnosis and is not a clinical diagnosis. CT scan is considered the preferred diagnostic method for reliable and rapid detection of pneumorrachis. In case of coexistence, The physician should be alert to diagnose and treat the underlying cause for related injuries.In such cases, successful results can be obtained with hyper-oxy therapy (100% oxygen inhalation) and antibiotic prophylaxis without the need for surgical treatment.

However, the prevalence of COPD or airflow obstruction in urothelial cancer patients has not been well studied.MethodsWe investigated the prevalence of airflow obstruction (FEV1/FVC

ConclusionNon-emphysematous gas trapping in the upper and lower lobes has a distinct physiological effect, especially in COPD with minimal emphysema. This local evaluation might allow sensitive detection of changes in lung hyperinflation in COPD.

Abstract Lung cysteine cathepsin S (CatS) that is a potent elastase plays a deleterious role in alveolar remodeling during smoke-induced emphysema. Despite the presence of a reactive nucleophilic cysteine (Cys25) within its active site, most of its elastinolytic activity is preserved after exposure to cigarette smoke extract (CSE), a major source of sulfhydryl oxidants. This result led us to decipher CatS resistance to major and representative CSE oxidants: hydrogen peroxide, formaldehyde, acrolein and peroxynitrite. CatS was inactivated by hydrogen peroxide, peroxynitrite and acrolein in a time- and dose-dependen...

Publication date: Available online 13 February 2020Source: Pharmacology &TherapeuticsAuthor(s): Kylie B.R. Belchamber, Louise E. DonnellyAbstractChronic pulmonary conditions now account for 1 in 15 deaths in the US and mortality is increasing. Chronic obstructive pulmonary disease (COPD) is due to become the 3rd largest cause of mortality by 2030 and mortality from other respiratory conditions such as asthma, idiopathic pulmonary fibrosis and cystic fibrosis are not reducing. There is an urgent need for novel therapies to address this problem as many of the current strategies targeting inflammation are not sufficient. ...

ConclusionRadiological findings of particular interest included the high burden of opacities observed and the presence of RCS ‐associated features in the majority of subjects. Radiologists are at the front line in occupational lung disease screening/diagnosis and must be aware of the imaging spectrum.
