Necrotizing FasciitisBrian VasquezAdrian VelazcoMonica VasquezJustin SookchanFernando Solis

Features Rare infection of the deeper layers of

skin and subcutaneous tissues. Progresses quickly Greater risk of developing in people with

compromised immune systems (diabetes, cancer, HIV +)

Necrotizing-dead Fasciitis-fascia

Underlying Causes A very severe form of necrotizing

fasciitis is caused by Streptococcus pyogenes. GAS bacteria

Usually caused by bacteria infiltrating minor cut or scrape.

The bacteria then grow and release toxins that kill tissue.

Organ Systems Necrotizing fasciitis affects the following

systems: Integumentary Muscle Immune Lymphatic Nervous

Prevalence Approximately 600 people contract

necrotizing fasciitis in the US each year. That equals about 1 in 453,333 people More males than females are affected (3

to 1) More prevalent in the

immunosuppressed.

Symptoms Small, red, painful lump on the skin

Changes to a very painful bruise-like area and grows rapidly, sometimes in less than an hour

The center may become black and die

The skin may break open and ooze fluid

Tests Usually visual diagnosis Can also use CT scan, blood tests, and

skin tissue biopsy.

Treatment

Treatment Powerful I.V. antibiotics Surgery to drain sore and remove dead

tissue Donor immunoglobulins (antibodies) Other treatments may include:

Skin grafts Amputation Hyperbaric Oxygen Therapy

Prognosis Depending on your overall health and

living situation, this disease will usually cause: Scarring and skin deformity Rapid death without proper treatment

Conclusion Necrotizing Fasciitis only affects 600

people annually, so there is no need to be worried.

Without proper treatment, this disease may cause severe deformities and possibly death.

As with all other diseases, time is a factor.
