How old is your neice and how long has she had this for, and has she suffered from any recent upper tract respiratory problems?
I would advise u to take her to a homeopathic doctor, as they may be able to assist the treatment.
I searched for some homeopathic doctors based in london and found:

Also, certain foods in your neices diet could be contributing towards her condition or delaying healing - they need to be eliminated from her diet straight away (e.g. starchy foods). And, certain foods and vitamins need to be added (esp Vitamin C). Would advise u to see a good and experienced nutritionist, who could offer some dietary advice on this, and help strengthen her body's natural resitance.
All of this combined will give your niece a better chance of recovering faster inshaAllaah.
May Allaah :arabic2: give her shifaa. Ameen.
