The cause of psoriasis is related to the immune system, and more specifically, a type of white blood cell called a T lymphocyte or T cell. Normally, T cells travel throughout the body to detect and fight off foreign substances, such as viruses or bacteria. If you have psoriasis, however, the T cells attack healthy skin cells by mistake as if to heal a wound or to fight an infection.


A-J display appearances of psoriasis lesions on typical areas of the skin. Lesions can be present on any area of the body. D is an example of minimal psoriasis. K-M are examples of psoriasis affecting fingernails. Although psoriasis-affected toenails can look very similar to this, people with athlete\'s foot may have similar-appearing toenails; therefore it is better to judge psoriasis by fingernail appearance alone. K and L display nail pits. M shows characteristic yellowish or brown color known as an "oil spot.“

  • You\'re exposed to the bacteria that cause impetigo when you come into contact with the sores of someone who\'s infected or with items they\'ve touched, such as clothing, bed linen, towels and even toys. Once you\'re infected, you can easily spread the infection to others.
  • Two types of bacteria cause impetigo — Staphylococcus aureus (staph), which is most common, and Streptococcus pyogenes (strep). Both types of bacteria can live harmlessly on your skin until they enter through a cut or other wound and cause an infection.
pediculosis lice infestation
PEDICULOSIS (Lice Infestation)
  • Getting head lice is not related to cleanliness of the person or his or her environment.
  • Head lice are mainly spread by direct contact with the hair of an infested person. The most common way to get head lice is by head-to-head contact with a person who already has head lice.
  • An estimated 6 million to 12 million infestations occur each year in the United States among children 3 to 11 years of age.

Types of Lice

The three types of lice that live on humans are:

  • Pediculushumanuscapitis (head louse),
  • Pediculushumanuscorporis (body louse, clothes louse), and
  • Pthirus pubis ("crab" louse, pubic louse).

Only the body louse is known to spread disease.

Most Common Sports Injuries

If you get hurt, stop playing. Continuing to play or exercise can cause more harm. Treatment often begins with the RICE (Rest, Ice, Compression and Elevation) method to relieve pain, reduce swelling and speed healing. Other possible treatments include pain relievers, keeping the injured area from moving, rehabilitation and sometimes surgery.
