7. Acne
Cause
Occurs when the openings of hair cells are blocked by dead epidermal cells.  The oil from the sebaceous glands gets trapped and a bacterium that lives on your skin starts to eat it-the product is something that causes irritation in our skin and leads to inflammation.
Genetic component, diet, hormone changes, exposure to oils or some cosmetics
Treatments 
Acne treatments work by reducing oil production, speeding up skin cell turnover, fighting bacterial infection, reducing the inflammation or doing all four.

19. Psoriasis
Description: A chronic (reoccurring) condition where the skin inflames and becomes covered in silvery scales
Cause: The epidermis continues to replicate uncontrollably (possibly because of antibodies stimulating the growth-but we really don’t know how or why).
Large genetic component

22. Eczema
Description
A reoccurring epidermal condition that causes dryness, flaking, redness, inflammation, and sometimes blistering and bleeding
Cause
Usually caused by an irritant you touch, an allergen you touch or consume, or hormone imbalances although there are many more causes. Either way, they cause an inflammation of the skin and irritation of the nerves.

25. Athlete’s foot Description:
Scaling, flaking, and itching of the infected area-can blister and crack the skin

28. Albinism
Description
Large patch of white skin, or the entire body is white, hair is white and irises of eyes are red
This lack of melanin leads to no protection from the UV of the sun. They are easily sun burned.
Cause
Genetic disorder. Their bodies do not produce an enzyme needed in the production of melanin.

32. Treatment Practice Key words/abbreviations Steps: Pt = patient
y/o = year old
CC = Chief Complaint
Steps:
Gather symptoms (observe)
Match symptoms to known diseases (evidence)
Draw conclusions (analysis)

33. Practice Diagnosis
16 y/o female presents with a CC of spots on her face. They are red and sometimes painful to touch. She cannot say when they started popping up, but does mention that she has been spending more and more time working and less time having fun with her friends. She is constantly checking her phone for updates about her boyfriend, who she is deciding whether or not to break up with.

She is constantly checking her phone for updates about her boyfriend, who she is deciding whether or not to break up with.

35. You Try! Practice Diagnosis
A 27 y/o male arrives at your office with a CC of what he refers to as “patches of skin that don’t match” the rest of his body. Upon further examination, you find lighter pigmented patched on his hands and feet. No other patches are present on his body. Pt states that the patches are not painful, itchy or irregular in any way except for their color.
