Nor does the DSM-5 place any arbitrary time limit on ordinary grief, in the context of bereavement â another issue widely misrepresented in the general media, and even by some clinicians.
Gas gangrene is commonly caused by infection with the bacterium Clostridium perfringens, which develops in an injury or surgical wound that's depleted of blood supply. The bacterial infection produces toxins that release gas â hence the name gas gangrene â and cause tissue death.
Dry gangrene can result from conditions that reduce or block arterial blood flow such as diabetes, arteriosclerosis, and tobacco addiction as well as from trauma, frostbite, or injury. Wet gangrene can result from the same causes as dry gangrene but always includes infection. In some cases of wet gangrene, the initial cause is considered to be the infection. Treatment for all cases of gangrene usually involves surgery, medical treatment, supportive care, and occasionally, rehabilitation.
