Pulmonary laceration is a common result of penetrating trauma but may also be caused by blunt trauma; broken ribs may perforate the lung, or the tissue may be torn due to shearing forces [5] that result from different rates of acceleration or deceleration of different tissues of the lung. [6]
The medullary cavity (medulla, innermost part) is the central cavity of bone shafts where red bone marrow and/or yellow bone marrow (adipose tissue) is stored; hence, the medullary cavity is also known as the marrow cavity.
Medulla oblongata, shown by a transverse section passing through the middle of the olive. (Medial medullary syndrome can affect structures in lower left: especially #5, #6, #8.) Specialty: Neurology Diagnostic method: Ipsilateral signs and symptoms - flaccid (lmn) paralysis and atrophy of one half of tongue (hypoglossal nerve)
Common causes include autoimmune diseases and connective tissue diseases. [2] Diagnosis of DAH is often given following observation of a patient presenting with hemoptysis, anemia, and cough, [3] along with a chest X-ray showing alveolar infiltrates in the lungs, [4] which are areas of air space in the lungs that are opacified and of higher ...
Multiple organ dysfunction syndrome (MODS) is altered organ function in an acutely ill patient requiring immediate medical intervention. [1]There are different stages of organ dysfunction for certain different organs, both in acute and in chronic onset, whether or not there are one or more organs affected.
A pulmonary contusion is another cause of bleeding within the lung tissue, but these result from microhemorrhages, multiple small bleeds, and the bleeding is not a discrete mass but rather occurs within the lung tissue. An indication of more severe damage to the lung than pulmonary contusion, a hematoma also takes longer to clear. [3] Unlike ...
End organ damage is severe impairment of major body organs due to systemic disease. Commonly this is referred to in diabetes, high blood pressure, or states of low blood pressure or low blood volume. [1] This can present as a heart attack or heart failure, pulmonary edema, neurologic deficits including a stroke, or acute kidney failure. [2]
Contusion involves hemorrhage in the alveoli (tiny air-filled sacs responsible for absorbing oxygen), but a hematoma is a discrete clot of blood not interspersed with lung tissue. [4] A collapsed lung can result when the pleural cavity (the space outside the lung) accumulates blood or air (pneumothorax) or both (hemopneumothorax). These ...
