Necrotizing pneumonia (NP), also known as cavitary pneumonia or cavitatory necrosis, is a rare but severe complication of lung parenchymal infection. [ 1 ] [ 2 ] [ 3 ] In necrotizing pneumonia, there is a substantial liquefaction following death of the lung tissue, which may lead to gangrene formation in the lung.
Type II infection more commonly affects young, healthy adults with a history of injury. [2] Type III infection: Vibrio vulnificus, a bacterium found in saltwater, rarely causes NF after it is introduced into the body through a break in the skin. [12] One in three patients with a V. vulnificus infection develop necrotizing fasciitis. [12]
The diagnosis of gangrene is based on symptoms and supported by tests such as medical imaging. [6] Treatment may involve surgery to remove the dead tissue, antibiotics to treat any infection, and efforts to address the underlying cause. [5] Surgical efforts may include debridement, amputation, or the use of maggot therapy. [5]
Necrosis is caused by factors external to the cell or tissue, such as infection, or trauma which result in the unregulated digestion of cell components. In contrast, apoptosis is a naturally occurring programmed and targeted cause of cellular death. While apoptosis often provides beneficial effects to the organism, necrosis is almost always ...
Patients may show up at the emergency room with life-threatening symptoms (such as massive hemoptysis or renal failure) or with nonspecific signs and symptoms (such as a rash, fever, myalgia, arthralgia, malaise, or weight loss) at their family physician's office. The size, location, and extent of the vessels involved all affect the manifestations.
Acute retinal necrosis (ARN) [1] is a medical inflammatory condition of the eye. [2] The condition presents itself as a necrotizing retinitis . [ 3 ] The inflammation onset is due to certain herpes viruses , varicella zoster virus (VZV), herpes simplex virus (HSV-1 and HSV-2) and Epstein–Barr virus (EBV).
In the study of people ages 65 and older, 8.15% of women treated by female physicians died within 30 days, compared with 8.38% of women treated by male physicians.
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 ]
