Gangrene



The word "gangrene" is derived from the Greek word gaggraina, which means "rot." Gangrene occurs as a result of the death and decomposition (necrosis) of tissues and begins with the appearance on the body of a small painful area of ​​a dark, almost black color. After a few days, dead tissue begins to fall off with flaps. The main causes of gangrene are inflammation of the arteries, which gradually leads to their blockage, and injuries leading to circulatory disorders.
See the article ARTERIA (PROBLEMS), with the addition that the problem is much more serious and requires an urgent solution. A person who has started gangrene enjoys life so little that it begins to subconsciously strive for self-destruction. He destroys himself from within, as he believes that he deserves nothing else.

Gangrene

  1. Gangrene
    Gangrene (gangraena). Putrefactive decay or gradual drying of tissues under the influence of microbes, autolysis and environmental factors is considered to be gangrene. In animals, gangrene of the skin and adjacent tissues, auricle, tongue, udder, penis, lungs, intestines, tail, distal part of the extremities is recorded, in birds - scallops, catkins, fingers. Etiology. Gangrene occurs when
  2. Gas gangrene
    Gas gangrene is a severe anaerobic infection of soft tissues, primarily muscles, accompanied by gas formation and severe intoxication. Etiology. Six most common pathogens of gas gangrene are distinguished: Clostridium perfringens, Clostridium novyi, Clostridium septicum, Clostridium histolyticum, Clostridium bifermentans, Clostridium fallax. All these microorganisms
  3. MYONECROSIS (GAS GANGRENA)
    Myonecrosis (gas gangrene) is an anaerobic wound infection that progresses from the moment of injury through the stages of cellulitis and myositis. The main causative agents of C.perfringens, other clostridia, mixed aerobic-anaerobic secondary infection. The choice of antimicrobial agents. Treatment is determined by the severity and location of the lesion. Antibiotic therapy is an important complement to surgical
  4. Laboratory lesson number 9 (2 hours)
    Subject: Necrosis, ulcers and fistulas .. Plan. 1. Definition and consideration of types of necrosis. 1.1. Students on schemes and photographs get acquainted with the causes of varieties of necrosis. 1.2. Dry skin gangrene. 1.3. Wet gangrene. 1.4. Gas gangrene. 2. Ulcers: definition and classification, etiology. 2.1. Simple ulcer. 2.2. Fungal (mushroom) ulcer. 2.3. Decubital
  5. Lung cavity syndrome
    A cavity in the lung tissue can occur due to the activity of pyogenic microbes (abscess), specific bacteria (tuberculous cavity), parasitic infection (echinococcus), decay of tumors, and more. The cavity may be one or more. Often it is initially closed, then a breakthrough in the bronchus (pleural cavity) occurs, and the cavity is filled with air. Leading symptoms: •
  6. Differential diagnosis of diabetic foot forms
    The neuropathic form is characterized by complaints of a violation of sensitivity (more in the feet), especially at night, paresthesia. This form of diabetic foot syndrome is clinically characterized by warm, dry skin of normal color, the presence of areas of hyperkeratosis in areas of excessive load pressure. Specific deformation of the feet, fingers, ankles, bilateral
  7. Malignant edema
    Malignant edema (Latin - Oedema malignum, septicaemia gangrenosa; English - Malignant oedema, gas gangrena, big head; wound gas edema, gas gangrene) - acute non-contagious wound toxicoinfection of animals and humans, caused by a group of pathogenic clasticia the formation of gases, necrosis of affected tissues and intoxication of the body
  8. Ergotism
    Ergotism is a disease that develops as a result of the consumption of products from grain containing an admixture of ergot. Ergot horns containing the microscopic fungus Claviceps purpurea develop on ears of rye, barley, less often wheat and are dark-purple horns. Ergot horns contain a number of alkaloids - ergotoxin, ergometrine, ergotamine, as well as histamine, tyramine, which have
  9. Twisting the lung
    Twisting of the lung is a rare result of severe chest injuries that cause the lung to rotate around the root. The x-ray picture is mirror with respect to the normal location of the bronchi, with the main pulmonary vessels directed more toward the head than down. Due to overflow of vessels, edema and atelectasis in the affected lung, the corresponding half of the diaphragm
  10. Soft tissue infections
    Most skin infections detected in ICUs are caused by many microorganisms, since they are the result of wounds from surgical or accidental injuries, pressure sores, therapeutic or illegal vascular punctures, or because they occur in patients with reduced immune defense and vascular insufficiency (especially diabetes). The most dangerous of these infections
  11. Sputum examination.
    Sputum for examination (mainly for the diagnosis of pulmonary-helminthic diseases and lung gangrene) is obtained by puncture of the trachea with a curved trocar, into the sleeve of which a sterile brush, brush or cotton swab is attached to the wire. Sputum can also be obtained through the mouth using a Gabriolavicius or Korikov device. Sometimes to obtain sputum in the oral cavity
  12. Ergotism
    Poisoning of animals with ergot alkaloids. It proceeds in a nervous or gangrenous form. Clinical signs. In horses, general depression, weakening of breathing, convulsions, paresis, and paralysis are noted. In the chronic course, gangrene of the extremities is layered, damage to the skin. In cattle, there is a violation of coordination of movements, muscle tremors, salivation, dilated pupils,
  13. Auricle frostbite
    Cause Prolonged exposure to low temperature in the ear. Symptoms Symptoms of mild frostbite of the auricle are redness, the formation of vascular spots. The skin is very sensitive and painfully sensitive to touch. The next degree of frostbite of the auricle is medium. It is characterized by swelling of the auricle and the formation of blisters. Symptoms III
  14. Necrosis
    1. Definition of the concept of "necrosis": a) anemia of an organ b) dystrophy c) plethora of an organ d) death of an organism e) necrosis of tissues in a living organism Correct answer: e 2. What type of indirect necrosis is there: a) toxic b) infectious c) traumatic d) wet d) trophoneurotic Correct answer: d 3. Microscopic signs of cell necrosis: a) fatty degeneration b) karyopycnosis c) karyokinesis
  15. Frostbite
    Long-term exposure to cold on certain parts of the body leads to the development of specific tissue damage. The basis of the pathogenesis of frostbite are neurovascular reactions that cause impaired tissue metabolism, tissue anoxia, cessation of blood circulation and thrombosis. Ultimately, necrosis and gangrene develop in places of frostbite. There are 4 degrees of frostbite: I - violation
  16. CLASSIFICATION
    According to ICD-10 of the revision / Tab. 6/, in the rubric 170 “Atherosclerosis” various concepts are included, some of which are presented below. Table 6 CLASSIFICATION OF ATHEROSCLEROSIS / ICD-10/170 Atherosclerosis 170.1 Atherosclerosis of the renal arteries / Goldblatt kidney /
  17. Coronary artery disease
    1. What is coronary heart disease: a) myocardial disease due to exogenous intoxication b) myocardial disease due to endogenous intoxication c) myocardial disease due to infection d) myocardial disease due to absolute or relative coronary insufficiency e) myocardial disease due to metabolic disorders Correct answer:
  18. Diabetic polyneuropathy
    It develops in people with diabetes. It can be either the first manifestation of diabetes, or occur in the later stages of the disease. In the pathogenesis of the disease, metabolic and ischemic disorders in the nerve are of the greatest importance due to micro- and macroangiopathies that accompany diabetes mellitus. Among the clinical options for diabetic polyneuropathy, several forms are distinguished: -
