Detailed Answer:
Hello XXXXXXX
Thanks a lot for sending the important details. The pictures will help us in deciding the exact nature and extent of problem and therefore the part of treatment. You please take time to send these pictures.
Now before I directly provide suggestions to your queries, let me elaborate some of the points regarding your mothers’ problem and therefore in your queries- Our skin is a multi-layered structure divided into
epidermis and dermis. This epidermis is again a superficial multilayered structure. The deepest of the layer of epidermis contains specific cells which are known as melanocytes.
These melanocytes are actually the color producing cells which have the tendency to produce color according to its own genetical tendency. Our skin daily produces pigment form the special cells called as melanocytes. In
vitiligo these cells stops secreting melanin.
Vitiligo occurs when the cells that produce melanin die or no longer produce melanin. This causes slowly enlarging white patches on our skin. There is no exact cause identified and defined but it is considered to be an auto-immune disorder where there is formation of
antibodies which works against the melanocytes.
The diagnosis of the vitiligo requires no any important instruments or tests and can be diagnosed by simple naked eye examination only. But in some cases where there is confusion then wood's lamp examination reveals the exact nature of hypo-pigmentation due to vitiligo or any other cause.
The causes of white hypo-pigmentation in sixties of life can be due to vitiligo or as
guttate hypomelanosis or as Post inflammatory hyperpigmentation(PIH).
In guttate hypomelanosis – there is hypopimented areas of pin head to slightly larger size and these never increase in size larger than few millimeters.
Post inflammatory hyperpigmentation – Thre hypopimented area at the previously inflamed or affected skin.
In any of these conditions our goal of treatment is to return the normal color by stopping or slowing the progression of pigment loss. There are multiple ways of treatment such as Steroid creams, Psoralen
photochemotherapy, topical psoralens and immunomodulator agents such as tacrolimus cream or
pimecrolimus cream locally. If the lesion is spreading one needs oral steroids for few months. IN your query, I can get that they are not increasing and not anywhere on the body. In these cases Topical psoralens (Melanocyl or Octomop) with steroids are the choice of treatment and we do not want to give any oral treatment.
All these therapies either halt the progression of activity and helps in production of color by melanocytes from the surrounding areas.
The only part is that it should be applied under dermatological supervision only as topical psoralens (Melanocyl or Octomop) can cause lot of irritation and redness. An important fact is that both Melanocyl and Octomop contain the same content of Methoxasalen1% and 0.75% respectively. In my patients I generally start with one of the lotions rather than using both.
As both of these lotions have strong irritation potential therefore it is to be diluted with distilled water. IN my patients I generally start with a proportion of 1:8 (1 part of lotion and 8 part of distilled water). It is to be applied at night time initially for few days to check for the irritation potential. If there is no irritation or redness then it is started in day time. The response is noted in 2 weeks interval and accordingly the proportion is reduced to 1:6 then 4 and 2 before applying the pure Melanocyl or Octomop. But it is a general rule that both the lotions are never combined on account of similar nature of contents as well as increase in irritation potential.
It takes minimum of 3 months of period to get good pigmentation. It also depends on the age of patient and the activity of the lesions (increasing or decreasing).
Now coming on your queries in the previous mail:
1) Current medication is using for the last 2 weeks and is she suppose to continue with it if yes then for how long
@ You can get from the above guiding points that she has to use the medications for at least minimum of 3 months to get good pigmentation. A good sign is that the
white spots have not increased since its appearance. As your mother is in her sixties, so it may take bit longer due to less production of color by melanocytes from the surrounding areas.
2) How much time will it take to cure and skin color match
@ As above
3)Is it due to allergy to mehandi that she applies on hair every week as of now she is using herbal mehandi-Shehnaaz/Ramdev
@ Mehandi if causing irritation then can cause both redness as well as later on white spots. So it is better to shift towards non-irritating products for hair color.
4) What all food/fruits she can take or avoid
@ Previously there was a dictum that people having vitiligo should avoid all sour things in the diet. But according to latest of studies as well as in my own personal experience I have not seen any increase in vitiligo despite consuming sour things. So in my view she can take all types of fruits, vegetable and eatables.
I hope these information will help you. I will be glad to answer any further queries.
"Wish you good health"
