Full recovery is common with proper treatment. [20] Pulmonary laceration usually heals quickly after a chest tube is inserted and is usually not associated with major long-term problems. [ 8 ] Pulmonary lacerations usually heal within three to five weeks, [ 12 ] and lacerations filled with air will commonly heal within one to three weeks but on ...
In blunt chest trauma, TBI occurs within 2.5 cm of the carina 40–80% of the time. [2] The injury is more common in the right main bronchus than the left, possibly because the former is near vertebrae, which may injure it.

[1] Other symptoms include coughing up mucus, wheezing, shortness of breath, fever, and chest discomfort. [2] The infection may last from a few to ten ...
These smooth muscle cells have muscarinic M 3 receptors on their membrane. The activation of these receptors by acetylcholine will activate an intracellular G protein , that in turn will activate the phospholipase C pathway, that will end in an increase of intracellular calcium concentrations and therefore contraction of the smooth muscle cell.
Costochondritis, also known as chest wall pain syndrome or costosternal syndrome, is a benign inflammation of the upper costochondral (rib to cartilage) and sternocostal (cartilage to sternum) joints. 90% of patients are affected in multiple ribs on a single side, typically at the 2nd to 5th ribs.
