Vitiligo
Vitiligo is a pigmentation disorder in the human skin. The human skin contains special skin cells (melanocytes) that produce the pigment melanin which colors the skin.
In Vitiligo, the special skin cells (melanocytes) as well as the tissues (mucous membranes) that line the inside of the mouth, nose, genital and rectal areas, and the retina of the eyes are destroyed. As a result, white patches of skin appear on different parts of the body. The hair may also turn white that grows in areas affected by vitiligo.
What causes vitiligo?
There are several theories regarding the cause of vitiligo but the actual cause is not fully known. According to one theory, people with vitiligo develop antibodies that, turn upon them and destroy their own melanocytes instead of protecting them. There is another theory according to which the melanocytes somehow attack and destroy themselves. Finally, some people with vitiligo have reported that a single event such as severe sunburn or an episode of emotional distress is the main cause of this order. Scientifically, events of this nature have not been accepted as the main cause of vitiligo. These are merely coincidences.
Who is affected by vitiligo?
The number of people affected by vitiligo (http://www.antivitiligo.com/vitiligo.html ) disorder ranges from 40-50 million. It forms about 1 to 2% of people in the world. 2 to 5 million people have the disorder in the United States alone.

Sterling Silver and Allergies to Metal
Sterling Silver and Allergies
The truth is people are not usually allergic to silver or sterling silver. Rather a metal known as nickel, which has been used in sterling silver. Sterling silver is an alloy consisting of 92.5% silver and 7.5% other metals, traditionally copper, and sometimes some manufacturers will use nickel in sterling silver as a less expensive alternative to other metals.
Why Sterling Silver?
Pure silver is too soft to produce any functional pieces and loses shape too easily. Other metals are added to improve qualities such as ductility, firescale, tarnish resistance, and reducing casting porosity.
Why Nickel?
Nickel, is a hard and ductile, silvery white metal that has been mistaken for silver in the past. Nickel is commonly used in jewelry including with precious metals jewelry such as gold, white gold, sterling silver and platinum and also most cheap or costume jewelry. Nickel is what gives white gold it’s white color by alloying more of it with yellow gold, as gold is not found naturally white or any other color than yellow. Other metals are used to make other colors of gold, for instance silver is used to make green gold and copper is used to make rose gold. Nickel adds many other properties besides color, such as strength and durability, and it has a strong lustrous effect. Read more
