Ventriculitis is the inflammation of the ventricles in the brain. The ventricles are responsible for containing and circulating cerebrospinal fluid throughout the brain. Ventriculitis is caused by infection of the ventricles, leading to swelling and inflammation.
Microscopically, Aschoff bodies are areas of inflammation of the connective tissue of the heart, or focal interstitial inflammation.Fully developed Aschoff bodies are granulomatous structures consisting of fibrinoid change, lymphocytic infiltration, occasional plasma cells, and characteristically abnormal macrophages surrounding necrotic centres.
Hypoxic infarcts in the brain presents as this type of necrosis, because the brain contains little connective tissue but high amounts of digestive enzymes and lipids, and cells therefore can be readily digested by their own enzymes. [6] Gangrenous necrosis can be considered a type of coagulative necrosis that resembles mummified tissue. It is ...
As defined, acute inflammation is an immunovascular response to inflammatory stimuli, which can include infection or trauma. [24] [25] This means acute inflammation can be broadly divided into a vascular phase that occurs first, followed by a cellular phase involving immune cells (more specifically myeloid granulocytes in the acute setting). [24]
Different diseases are associated with coagulative necrosis, including acute tubular necrosis and acute myocardial infarction. [ 2 ] Coagulative necrosis can also be induced by high local temperature; it is a desired effect of treatments such as high intensity focused ultrasound applied to cancerous cells.
Experts say it could ‘revolutionise the way we diagnose myocarditis’, allowing early treatment and support.
Endocarditis is an inflammation of the inner layer of the heart, the endocardium. It usually involves the heart valves. Other structures that may be involved include the interventricular septum, the chordae tendineae, the mural endocardium, or the surfaces of intracardiac devices.
The death of an Oregon house cat and a pet food recall are raising questions about the ongoing outbreak of bird flu and how people can protect their pets. Bird flu has been spreading for years in ...
