Inflammation normally occurs as a second response when damage tissues. Inflammation can occur immediately however
Sepsis is a life threatening illness where the patient’s body responds improperly to an infection. The patient’s immune system goes into overdrive as a response to an infection. Sepsis develops with the chemicals that the immune system releases into the blood stream as the body fights the infection. The infection causes inflammation throughout the entire body (systemic) and can be very difficult to treat. Sepsis is also known as Systemic Inflammatory Response Syndrome (SIRS). There are three stages of Sepsis: Sepsis, severe Sepsis, and Septic shock. As Sepsis spreads though out the body via the blood stream, the inflammation spreads. Once a patient gets to the Septic shock stage, the patient is in grave danger and the patient’s bodily functions
Describe the series of events that occur in skin, which is healing with the help of a skin graft?
Fluid building up in the tissues caused by an inflammation response, triggered by the repeated stresses on the tissues, can lead to maceration of the deeper tissues, resulting in wounds and ulcers. Especially in patients with limited healing due to circulation conditions and diabetes, or those suffering peripheral neuropathy (Fig 3)
The word “sepsis” is derived from the ancient Greek word for rotten flesh and putrefaction. Since then, a wide variety of definitions have been applied to sepsis, including sepsis syndrome, severe sepsis, bacteremia, septicemia and septic shock In 1991, the American College of Chest Physicians (ACCP) and the Society of Critical Care Medicine (SCCM) developed a new set of terms and definitions to define sepsis in a more “precise manner” [1, 2]. These definitions take into account the findings that sepsis may result from a multitude of infectious agents and microbial mediators and may not be associated with detectable bloodstream infection. The term “systemic inflammatory response syndrome” (SIRS) was coined to describe the com- mon systemic response to a wide variety of insults. When SIRS was the result of a suspected or confirmed infectious process, it is termed “sepsis”.
When an inflammatory response happens white blood cells release endotoxins and exotoxins that destroy the bacteria causing infection. However, these toxins also cause damage to the surrounding blood vessels and therefore leak into the
Proliferative phase occurs within a few days of injury in which cells that were involved in the battle need to tend to their wounds and the regenerate to restore itself to its formal glory as best as possible. The body’s way of restoring itself is through use of angiogenesis, granulation tissue formation, wound contraction and epithelialization. This combination acts of getting new blood vessels to the damage area, aid in the formation of cells to fill in the area which leads to scar tissue, allow the skin to flexible in the repair process and finally resurface the wound with new epithelial
A pre-existing health condition started to intensify. He could hardly walk due to the inflammation in his foot, on top of this, flaring red patches were showing up on his skin. He was eventually diagnosed with an auto-immune disease known
The major signs of inflammation are pain, swelling, redness, and heat. The main reason for these signs in the presence of inflammation are (i) Pain is due to chemicals released by the nerve endings, provoking the area to be more sensitive. (ii) Swelling is caused by fluid buildup around the blood vessels of the affected area. (iii) Redness occurs because the capillaries in the affected area are filled with more blood than usual. (iv) Heat is the result of more blood flow in the affected area, that makes it feel warm to the touch.
Septic shock is a type of systemic inflammatory response syndrome, or SIRS, (Heuther & McCance, 2012, p. 632) secondary to a documented infection (Hadjiliadis et al., 2014). The process of septic shock is as follows: sepsis, followed by severe sepsis, then septic shock, and finally multiple organ dysfunction syndrome, or MODS (Heuther & McCance, 2012). The clinical manifestations of each individual, which will be discussed later, depend on where they fall in this process. It should also be noted that septic shock can affect any part of the body, such as the heart, brain, and intestines (Hadjiliadis et al.,
When the cell is inflamed the inflammation sends signals to integrins, which interact with proteins in the walls of the blood vessels. White blood cells then surround the inflamed tissue to fight infection as a result of integrin mediation.
When tissue injury occurs, a network of chemical signals activate a host response which is designed to protect and heal the damaged tissues (i.e. inflammation) (Coussens & Werb, 2002). This process involves the activation and migration of leukocytes (neutrophils, monocytes, and eosinophils) to the site of damage as well as recruitment of tissue mast cells (Coussens & Werb, 2002). Additionally, this inflammatory response involves migration of macrophage progenitors, which travel through the venous system to the site of injury. This migratory process is directed to the site of tissue damage by a host of chemotactic factors, among these are cytokines including interleukin-1β (IL-1β) and
Pustules with surrounding edema and erythema are produced as a result of increased permeability of local blood vessels and the subsequent infiltration of neutrophils, lymphocytes and macrophages. Cell-mediated immune response is a prerequisite for lesion
Toxic shock syndrome, is a life threatening bacterial infection that can be caused by either staphylococcus aureus or group A streptococcus. The associated symptoms of toxic shock syndrome are high fever, low blood pressure, and sunburn like rash that affects mostly the palms of the hands and the sole of the feet , redness of the mouth, throat, and eyes (Mayo clinic, 2014).
