Ch 4 Integument System

Skin Problems –

infections, allergies, or damages

1 athlete s foot
1. Athlete’s Foot

– mostly from fungal infection

2 boils carbuncles
2. Boils & Carbuncles

Bacterial infection & inflammation of hair follicle.

  • Boil = 1
  • Carbuncle = several connected boils
3 black whiteheads
3. Black & Whiteheads
  • Blackheads - oil and dead skin cells trapped in a oil pore, makeup
  • Whiteheads - flesh-or white-colored bumps due to skin pore blockage; blockage is deeper than blackhead (covered w/epithelium)
4 cold sores
4. Cold Sores
  • Caused by Herpes simplex virus I
  • Common, contagious, incurable
5 contact dermatitis
5. Contact Dermatitis
  • Inflammatory response – red, itchy rash
  • Non-contagious
  • Chronic – long term, reoccuring
  • Caused by contact with allergens or irritants, exposure to sunlight, or by poor circulation, even stress.
6 impetigo
6. Impetigo
  • Crusting skin infection
  • Caused by staph and strep germs
  • Pus filled blisters
  • Highly contagious
7 psoriasis
7. Psoriasis
  • Chronic – arms, knees, elbows, scalp
  • Red patches covered with white scales
  • Unknown cause; some think autoimmune disorder
  • Triggered by trauma, infection, stress
8 cyanosis
8. Cyanosis
  • Blue skin, membranes, and/or nails
  • Due to reduced oxygen in blood
9 burns
9. Burns
  • Tissue damage and cell death caused by heat, electricity, UV radiation, or chemicals
  • Associated dangers

- Dehydration

- Electrolyte imbalance

- Circulatory shock

rules of nines
Rules of Nines
  • Way to determine the extent of burns
  • Body is divided into 11 areas for quick estimate
  • Each area represents ~ 9%
burns are critical if
Burns are CRITICAL if…
  • Over 25% of body has 2nd degree
  • Over 10% has 3rd degree
  • 3rd degree burns on face, hands, and/or feet

Contact Burn

Electrical

Heat Burn

Scald Burn

Sunburn

Inhale Burn

Chemical

10 skin cancer
10. Skin Cancer

Abnormal cell mass

Two types

1. Benign

-does not spread (encapsulated)

2. Malignant

-Metastasized (moves) to other parts of body

Skin cancer is most common type of cancer.

3 types of malignant skin cancer
3 types of Malignant Skin Cancer

A. Basal cell carcinoma

- least malignant

- Most common

  • Arises from stratum basale

B. Squamous Cell Carcinoma

  • -arises from stratum spinosum
  • Metastasizes to lymph nodes
  • Early removal allows a good chance of cure
slide16
C. Malignant Melanoma
  • Most deadly
  • Cancer of melanocytes
  • Metastasizes rapidly to lymph & blood vessels
  • Detection uses ABCD rule.
abcd rule
ABCD Rule

A = Asymmetry

  • Two sides of pigmented mole do not match

B = Border irregularity

  • Borders of mole are not smooth

C = Color

  • Different colors in pigmented area

D = Diameter

  • Spot is larger then 6 mm in diameter
albinism
Albinism
  • Genetic recessive
hyperpigmentation
Hyperpigmentation
  • too much sun
  • drug reactions
  • poor nutrition
vitilgo
Vitilgo
  • autoimmune disorder
  • linked hyperthyroidism & Addison's Disease, which affects the adrenal gland.
lichen simplex chronicus
Lichen simplex chronicus
  • psychological syndrome
  • compulsive need to scratch
  • dark, leathery skin
  • scarring & infection
melasma
Melasma
  • Pregnancy mask
  • Lupus (autoimmune)
normal discolorations
Normal Discolorations
  • Moles - collection of melanocytes
  • Freckles – some cells make more melanin than others; uneven suntan.
  • Lentigines - Age spots, sun spots, liver spots - harmless, flat, brown discolorations on the hands, neck & face 40+ yrs; too much sun
  • Birthmarks – pigmented areas or dilated blood vessels
