Inflammation

What is it?

What are the stages, and occurrences in those stages?

Extensions?

Human Biology


Inflammation

  • Attempt to restore homeostasis in an area.

  • Injury…the inflammatory response is initiated. Protective, defensive.


Inflammation

  • Etiologies:

    • Mechanical Trauma

      • MVC (collisions), Knife Wounds, Gunshots, Surgery, twisting an ankle, knee.

    • Foreign invaders (like bacteria)

      • Toxins. Entrance though skin breaks (burn, splinter, wounds)


Inflammation

  • Symptoms

    • Erythema

      • Redness, heat

    • Pain

    • Edema (swelling)

Lymphedema

Damaged, absent, malformed vessels

Note: This is showing you an illustration of edema, and not the entire inflammatory response.

Inflammation has five basic stages:

Vasodilation

Phagocyte Migration

Nutrient/Metabolic Increase

Fibrin Formation

Pus Formation


Inflammatory Stages

1) Vasodilation and increased permeability of blood vessels.

  • Histamine release does this at the site of damage. Pain from damages nerve endings.

    • Chemical released during allergy, inflammatory response.

  • Causes redness and swelling


Inflammatory Stages

2) Phagocyte migration

  • White Blood cells engulf and destroy bacteria and dead tissue.

Inflammatory Stages

3) Release of nutrients/Metabolic increase

  • Need more energy to fight infection/wounds.

  • Cellular respiration increase

Need more energy

To deal with this

Inflammatory Stages

4) Fibrin Formation

  • Soluble protein called fibrinogen coverts to fibrin.

  • Traps bacteria at the site to isolate infected/damaged area.

Inflammatory Stages

5) Pus Formation

  • Thick fluid containing live cells, dead cells, bacteria, white blood cells.

Maggot Therapy


Do you doubt the effectiveness of this treatment??

  • The pictures you will see are proof that maggot therapy can help patients that have not responded to conventional therapy.


Gangrenous ulcerations

Patient was in hospital

for 5 weeks, receiving IV

antibiotics and surgery.

Doesn’t look too good.


Two weeks later, after maggots have been applied. See the healthy tissue? It is red and bloody, but healthy.


3 Months later…

An excellent result.

The scarring will fade

over the coming months.


Surgeons had a tough time figuring out which was good tissue and bad tissue, due to the advanced nature of the ulceration. They didn’t want to cut too much away.

3 years of foot ulcers in this 70 yr. old patient.


After maggots were applied, the wound was cleaned, and the dead tissue was removed. As you can tell, the maggots did a much better job than the surgeons could.


After healing, the wound looks fantastic.

Two years afterwards, the wound had not reoccurred.
