Have you ever seen people walking around with white patches all over there body? Do you ever wonder what condition or disease that person may have? Do we at times just these people and look down on them just because they look different? What is our reaction when we see a person walking on the street that has white patches all over them? Are we quick to judge, or do we simply look at it as they have a health problem and there's nothing wrong with that? Do some of us even know what those white patches on the skin may mean? Those white patches that we at times see in some people are a condition known as Vitiligo. Vitiligo is medically known for being an auto-immune disease. An auto-immune disease simply means that the person's own immune system attacks its own tissues and in some cases their organs. When a person has vitiligo, their melanocytes are destroyed or killed off and they start to get pigmentations (white patches) on different parts of their bodies. The parts of the body that may get pigmentations are: the hands, feet, face, the inside of the mouth, genitals, rectum, and in some cases the persons hair may turn white because of the vitiligo. In other cases of vitiligo, the mucous membranes (tissues that line the inside of the mouth and nose) and the retina (inner layer of the eyeball) can be affected. The cause of vitiligo is still unknown, but some scientists and doctors have developed a few theories about its origin. Some scientists and doctors believe that heredity comes into play. This theory I can believe because my grandmother and aunt both have vitiligo. Others have said that sun burn, stress, alopecia areata (balding before the age of 35), hyperthyroidism (over active thyroid gland), and some immune diseases may develop vitiligo. Another theory of how one gets vitiligo is said to be, the inheritance of 3 genes that make it capable of the skin becoming depigmented. In a healthy human being, the body produces proteins that are called cytokines. When a person has vitiligo, the cytokines alters the cells that produce pigments and cause them to die.

Vitiligo Research Paper

...What is vitiligo? Vitiligo is a disease that causes the loss of skin color in blotches.The patches appear when melanocytes in the skin die off. Melanocytes are the cells responsible for producing the skin pigment, melanin, which gives skin its color and protects it from the sun's UV rays.It can also affect the eyes, the inside of mouth, and the hair. In most cases, the affected areas remain discolored for the rest of the person's life. The only symptom of vitiligo is the appearance of flat white spots or patches on the skin. The first white spot that becomes noticeable is usually in an area that tends to be exposed to the sun. Although, it does not cause any discomfort, irritation, soreness, or dryness in the skin. The areas that are affected will be more sensitive to sunlight than those that are not. As for treatment, the American Academy of Dermatology (AAD) describe vitiligo as "more than a cosmetic problem." It is a health issue that needs medical attention. There are many natural and home remedies that seem to reduce the visibility of vitiligo. For example, research indicates that ginkgo biloba can help treat vitiligo because of its antioxidant and immunomodulatory properties. It can help reduce the...

...treatable and some of them are permanent. One of the visible autoimmune diseases is vitiligo. Vitiligo occurs when melanocytes die or stop producing the pigment that gives a skin, hair, and eye color. When people have vitiligo the skin becomes whiter, and it usually occurs on skin on both sides of the body. The exact trigger is not known, but it relates to the immune system to attack, destroy the melanin-forming cells because of the family history, sunburn, stress, or exposure to chemicals. It can happen at any age, but usually occurs before the age 20. In the article “For Vitiligo Patient, Arthritis Drug Restores Skin Color” from June 24, 2015 says that a medication for treating rheumatoid arthritis has given the color back to the skin in a patient with vitiligo. It is reported that steroid creams and light therapy are not as effective in reversing the pigmentation. Yale investigators decided to use FDA-approved medication (Janus kinase inhibitors). The patient was given tofacitinib, before this medication the patient’s white spots were increasing. After two months the results were seen, patient had repigmentation on the face, arms, and hands. After five months, this white spots were almost gone; the patient had only several white spots left on the body. There were no negative results seen using tofacitinib. The scientists believe that this could be a breakthrough in the treatment of vitiligo. Brett King, M.D., assistant professor of dermatology and principal investigator of...

Why Is Uncle Ruckus Wrong

...forgiveness for being black is to rebuke your own race. He has a glass eye from the beatings he received by his father, though his eyes are portrayed as always having been mismatched. Ruckus champions the small traces of French, Native American or Irish ancestry he claims to have (though a first DNA test showed he was "102% African" with a 2% margin of error -- later in that episode, due to BET's deliberate tampering with the results, it states that he is 50.07% white/Caucasian to cheer him up), and wishes that all black people were still enslaved or never existed at all. He prattles white supremacist rhetoric and calls Michael Jackson (who suffered from the pigmentational skin changing disorder vitiligo) a "lucky bastard", as he no longer was black. Ruckus claims that he himself has "re"-vitiligo, to explain his own skin tone. According to a flashback scene, he, in his late teens protested against Martin Luther King's marches during the Civil Rights Movement and would occasionally throw bricks at King, but usually missed. Another flashback scene shows Ruckus serving on a jury in 1957 (making him a minimum of 70 circa 2009 although this flashback does not match with the show's continuity) in Tennessee that helped convict a blind black man of killing three white girls. In spite of being blind, the African American man supposedly shot the three with a Winchester rifle from about 50 yards away. (Ruckus is the only black person on the otherwise all white jury, in what is a Jim Crow courtroom...

It has three main layers, the epidermis, the dermis and the subcutaneous layer. The epidermis is an elastic layer on the outside that is continually being regenerated. It includes the following: Keratinocytes - the main cells of the epidermis formed by cell division at its base. New cells continually move towards the surface. As they move they gradually die and become flattened. Corneocytes - the flattened dead keratinocytes that together make up the very outer layer of the epidermis is called the stratum corneum or horny layer. This protective layer is continually worn away or shed. Melanocytes – produce the pigment melanin that protects against UV radiation and gives skin its colour. The dermis is the inner layer that includes the following: Sweat glands – produce sweat that travels via sweat ducts to openings in the epidermis called pores. They play a role in temperature regulation...

Drug Abuse and Michael Jackson's Death

...DEATH OF MICHAEL JACKSON- FACTS AND FICTIONS The death of Michael Jackson has prompted an explosion of rumor that has grown more lurid with every day that passes. Now more than a year since he died, there is no let-up in the speculation. But what are the facts, and what are the fictions? What do we know for sure about why he died? On June 25, 2009, American singer Michael Jackson died after he suffered cardiac arrest at his home in the Holmby Hills neighborhood in Los Angeles, California. His personal physician, Conrad Murray, said he found Jackson in his room, not breathing but with a faint pulse, and that he administered CPR to no avail. Jackson was treated by paramedics at his home, but was pronounced dead at the Ronald Reagan UCLA Medical Center.

The skin protects us from microbes and the elements, helps regulate body temperature, and permits the sensations of touch, heat, and cold. Skin has three layers: * The epidermis, the outermost layer of skin, provides a waterproof barrier and creates our skin tone. * The dermis, beneath the epidermis, contains tough connective tissue, hair follicles, and sweat glands. * The deeper subcutaneous tissue (hypodermis) is made of fat and connective tissue. The skin’s colour is created by special cells called melanocytes, which produce the pigment melanin.
