Injectable filler is a special type of substance made for injections into connective tissues, such as skin, cartilage or even bone, for cosmetic or medical purposes.The most common application of injectable fillers is to change one's facial appearance, but they also are used to reduce symptoms of osteoarthritis, treat tendon or ligament injuries, support bone and gum regeneration, and for ...
Thermal effects (extremely high or low temperature) can often result in necrosis due to the disruption of cells, especially in bone cells. [16] Necrosis can also result from chemical trauma, with alkaline and acidic compounds causing liquefactive and coagulative necrosis, respectively, in affected tissues. The severity of such cases varies ...
These days, Botox and other neuromodulators have become incredibly normalized, but that doesn't mean these kinds of cosmetics procedures should be taken lightly. Botox, after all, is still a ...
If avascular necrosis involves the bones of a joint, it often leads to destruction of the joint articular surfaces (see osteochondritis dissecans). Testicle : an infarction of a testicle is commonly caused by testicular torsion and may require removal of the affected testicle (s) if not undone by surgery quickly enough.
Liquefactive necrosis (or colliquative necrosis) is a type of necrosis which results in a transformation of the tissue into a liquid viscous mass. [1] Often it is associated with focal bacterial or fungal infections, and can also manifest as one of the symptoms of an internal chemical burn . [ 2 ]
Avascular necrosis (AVN), also called osteonecrosis or bone infarction, is death of bone tissue due to interruption of the blood supply. [1] Early on, there may be no symptoms. [1] Gradually joint pain may develop, which may limit the person's ability to move. [1] Complications may include collapse of the bone or nearby joint surface. [1]
Dysbaric osteonecrosis or DON is a form of avascular necrosis where there is death of a portion of the bone that is thought to be caused by nitrogen (N 2) embolism (blockage of the blood vessels by a bubble of nitrogen coming out of solution) in divers. [1] Although the definitive pathologic process is poorly understood, there are several ...
There are two types of pyknosis: nucleolytic pyknosis and anucleolytic pyknosis. Nucleolytic pyknosis occurs during apoptosis (a form of controlled/programmed cell death), while anucleolytic pyknosis occurs during necrosis. [4] Necrosis is a form of regulated cell death due to toxins, infections, and other acute stressors. [4]
