Abstract

In 1975, France will have manufactured 3.2 million tons of plastic materials which by pyrolysis, liberate chlorine, methyl chloride, hydrocyanic acid, hydrofluoric acid and other toxic gases. Now these materials are burnt in fires in "modern", buildings or vehicles , associated with fats (acrolein) and other gases and toxic industrial or household fumes which attack the lung. At sufficient dosage these agressive agents have first of all a "suffocating" action when in case of survival, a caustic and corrosive action. Pulmonary edema of the lesional type is met with at two stages in these cases. They are due to a direct action on the bronchial epithelium and an indirect action by disturbance of surfactant metabolism. It is an edema which is interstitial above all, and secondarily endo-alveolar. Study of the clinical, radiological, bronchoscopic and hemodynamic symptomatology. Differential diagnosis is not always easy. The possibility of burns of the respiratory pathways, blast, must be looked at. These elements can moreover be associated with lesions due to toxic inhalation. In case of survival the course is one of fibrosis with a restrictive syndrome.

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Pontocerebellar Hypoplasia

Pontocerebellar hypoplasias are a group of neurodegenerative autosomal recessive disorders with prenatal onset, atrophy or hypoplasia of the cerebellum, hypoplasia of the ventral pons, microcephaly, variable neocortical atrophy and severe mental and motor impairments. Here is the latest research on pontocerebellar hypoplasia.

Cell Atlas Along the Gut-Brain Axis

Profiling cells along the gut-brain axis at the single cell level will provide unique information for each cell type, a three-dimensional map of how cell types work together to form tissues, and insights into how changes in the map underlie health and disease of the GI system and its crosstalk with the brain. Disocver the latest research on single cell analysis of the gut-brain axis here.
