Description And Treatment Of Vitiligo
Vitiligo is a complex disease associated with selective and progressive loss of melanocytes from epidermal basal layer resulting in white patches, commonly on the skin and occasionally on mucosae. It is also known as leukoderma or phulwari in India. The condition is non-contagious and asymptomatic but is associated with a significant psychosocial implication leading to an exaggerated sense of humiliation, loss of self-esteem and job discrimination among patients. Worldwide prevalence of vitiligo is around 1%, whereas it is more common in India with a prevalence of around 4% (range- 0.46% to 8.8%) [1, 2].
The clinical features of vitiligo are variable, initially starting as hypopigmented and then depigmented macules, patches and widespread

Although medical treatment is the mainstay of treatment, it is not uniformly effective in all patients and a residual lesion further requires surgical intervention to achieve complete repigmentation. The key principle of treatment is to induce repopulation of active melanocytes that are able to migrate into, proliferate, and thus repopulate the depigmented skin. The proper selection of cases for surgical therapy is of paramount importance and the stability of the vitiligo is taken as the most important parameter before opting for any transplantation technique. Various authors have recommended different periods of stability varying from 4-months to 3-years, but none of these criteria are based on the evidence obtained from a systematic …show more content…
Dermabrasion was done until tiny pinpoint bleeding spots were seen indicating the dermo-epidermal junction and was extended 5-mm beyond diseased margin to prevent halo phenomenon. The denuded area was washed with PBS and covered with a PBS moistened gauze piece. The NCES (in subgroup A) and the 1:1 combination of NCES and NDCS (in subgroup B) were carefully transferred to a tuberculin syringe. Using 18-gauge needle, few small drops of suspension were placed over the denuded surface and were evenly spread. This was covered with sterile Vaseline gauze (Unilever, London, UK) or Bactigras dressing (Smith & Nephew Pty Ltd, Victoria, Australia) after washing with NS. Few more drops of suspension were placed over this gauze and spread evenly. After washing with normal saline, a meshed collagen sheet (Kollagen M, Eucare pharmaceuticals, TN, India) was placed over the gauze with suspension. This was then covered by a small gauze piece moistened with PBS. Tegaderm (3M Medical, MN, USA) was placed to help form an artificial blister which would hold melanocytes with PBS over the recipient site. At difficult areas, such as lips, surgical glue was used to hold Tegaderm in place. The surgical pad dressing was done and fixed using elastic plaster (Dynaplast, Johnson & Johnson, NJ,

    People are now seeing the truth, but even if they know what's happening to them it's important to know the reasons it's happening . To get down to basics there are five clinical types of melanoma. The most common form is called the superficial spreading melanoma and it about 70% of all melanoma cases. It is commonly found on the truck in men and on the legs in woman (Joan 4). Many people get confused on what melanoma is. Melanoma is a tumor of melanin-forming cells, melanin cells are cells that have turned dark brown by the overexposure of sun. Basal and squamous are a less deadly form of skin cancer also caused by the overexposure of sun. It's important for us to know why skin cancers specifically the more deadly ones like melanoma are spreading and the answer is very clear. While basal and squamous cell cancers tend to invade locally, melanoma spreads very quickly to other parts of the body ( Egan 6). The unfortunate part is that people today are finally getting the information they need. In the past people didn't know that sun burns and not wearing sunscreen could affect them so much in the future. Between 40 and 50 percent of Americans who live to age 65 will have either basal cell carcinoma or squamous cell carcinoma at least once ( Steve 6). Although the number is still increasing with more awareness it can be easy to…

    On November 15th, 2005 it was marked five years for Craig, a melanoma survivor. Craig states, “I was an outdoor person who thought it wouldn’t happen to me, but it did at a very young age.” Craig was diagnosed with melanoma in his left ear lobe at a self-conscious age of 21 years old. He had a two cm wedge resection and had some lymph nodes removed for testing to make sure it hadn’t spread. About a year later, a lump appeared on his left side of his neck. It was found to be secondary melanoma and spread to his lymph glands in his neck. He lost a quarter of muscles in his neck and most of his lymph nodes but not his determination. It has been the five year mark but there is a five percent chance the same melanoma can reoccur. Craig was a lucky cancer survivor from the deadliest skin cancer. Melanoma is just one of the side effects of the sun and indoor tanning is the new addiction for our generation instead of going out and getting the natural vitamin D.…
