Acne
Acne is a common skin disease that causes pimples. Pimples form when hair follicles under your skin clog up. Most pimples form on the face, neck, back, chest, and shoulders. Anyone can get acne, but it is common in teenagers and young adults. It is not serious, but it can cause scars . No one knows exactly what causes acne. Hormone changes, such as those during the teenage years and pregnancy, probably play a role. There are many myths about what causes acne. Chocolate and greasy foods are often blamed, but there is little evidence that foods have much effect on acne in most people.

Biopsy
A biopsy is a procedure that removes cells or tissue from your body. A doctor called a pathologist looks at the cells or tissue under a microscope to check for damage or disease. The pathologist may also do other tests on it. Biopsies can be done on all parts of the body. In most cases, a biopsy is the only test that can tell for sure if a suspicious area is cancer. But biopsies are performed for many other reasons too. There are different types of biopsies. A needle biopsy removes tissue with a needle passed through your skin to the site of the problem. Other kinds of biopsies may require surgery.
Body Lice
What are body lice? Body lice (also called clothes lice) are tiny insects which live and lay nits (lice eggs) on clothing. They are parasites, and they need to feed on human blood to survive. They usually only move to the skin to feed. Body lice are one of the three types of lice that live on humans. The other two types are head lice and pubic lice . Each type of lice is different, and getting one type does not mean that you will get another type. Body lice can spread diseases, such as typhus, trench fever, and relapsing fever. How do body lice spread? Body lice move by crawling, because they cannot hop or fly.

Breast Reconstruction
If you need a mastectomy , you have a choice about whether or not to have surgery to rebuild the shape of the breast. Instead of breast reconstruction, you could choose to wear a breast form that replaces the breast, wear padding inside your bra, or do nothing. All of these options have pros and cons. What is right for one woman may not be right for another. Breast reconstruction may be done at the same time as the mastectomy, or it may be done later on. If radiation therapy is part of the treatment plan, your doctor may suggest waiting until after radiation therapy.
Burns
A burn is damage to your body's tissues caused by heat, chemicals, electricity , sunlight , or radiation . Scalds from hot liquids and steam, building fires and flammable liquids and gases are the most common causes of burns. Another kind is an inhalation injury , caused by breathing smoke. There are three types of burns: First-degree burns damage only the outer layer of skin Second-degree burns damage the outer layer and the layer underneath Third-degree burns damage or destroy the deepest layer of skin and tissues underneath Burns can cause swelling, blistering, scarring and, in serious cases, shock , and even death.

Dietary Proteins
Protein is in every cell in the body. Our bodies need protein from the foods we eat to build and maintain bones, muscles and skin. We get proteins in our diet from meat, dairy products, nuts, and certain grains and beans. Proteins from meat and other animal products are complete proteins. This means they supply all of the amino acids the body can't make on its own. Most plant proteins are incomplete. You should eat different types of plant proteins every day to get all of the amino acids your body needs. It is important to get enough dietary protein. You need to eat protein every day, because your body doesn't store it the way it stores fats or carbohydrates.

Scratching the skin can cause it to turn red, and to swell and itch even more. Eczema is not contagious. The cause of eczema is unknown. It is likely caused by both genetic and environmental factors.

It often causes a bright red rash on their cheeks (sometimes called a "slapped cheek" rash). In the United States, parvovirus B19 infections are more common in late winter, spring, and early summer. There are usually minor outbreaks of fifth disease about every 3 to 4 years.

Hidradenitis Suppurativa
What is hidradenitis suppurativa (HS)? Hidradenitis suppurativa (HS) is a chronic skin disease. Another name for it is acne inversa. It causes painful, boil-like lumps that form under the skin. It often affects areas where the skin rubs together, such as your armpits and groin. The lumps become inflamed and painful. They often break open, causing abscesses that drain fluid and pus. As the abscesses heal, they can cause scarring of the skin. What causes hidradenitis suppurativa (HS)? The lumps in HS form because of blockages of the hair follicles. The blocked hair follicles trap bacteria, which leads to inflammation and rupture.
