How CAN I banish my embarrassing rosacea?
I’VE had rosacea for years and tried many different creams, but nothing stops the redness. It’s so embarrassing. I’m 70 and only drink now and again. Can you help? Mrs M. North, Dronfield, Derbys.
Your situation is understandably distressing. rosacea is a common skin condition that mainly affects the cheeks and nose.
It often begins with episodes of flushing, when the skin turns red briefly, but this may progress to permanent redness. Some people also have inflammatory spots.
We don’t know exactly what causes rosacea. It may be a disorder of the immune system, be linked to the way some people react to the tiny mites that live in the pores or to the bacteria naturally present on the skin.
Strong sunlight, spicy food, alcohol, stress, strenuous exercise and extremes of temperature can cause the blood vessels in the face to expand excessively, triggering the flushing and making the condition worse.
The triggers vary with the individual, but it’s important to avoid those things that cause flushing in your particular case.
Treatments are aimed at suppressing the symptoms and need to be adhered to long term.
Most patients find oral antibiotics effective — we typically prescribe tetracycline at 250mg a day, which reduces inflammation.
Many are reluctant to continue with antibiotics for a long time, perhaps because of concerns over antibiotic resistance or upsetting their gut bacteria.
However, I must stress that at this low dose they are not very likely to have these effects and the symptoms will return once Another you stop taking them. option is a cream containing the antibacterial agents metronidazole or azelaic acid. These have long been prescribed for rosacea and work by suppressing the bugs in the skin. But, again, they will only minimise the condition rather than stop it altogether.
A newer treatment you will not have tried is a gel containing brimonidine ( brand name Mirvaso). It was developed as a treatment for glaucoma, but has since been shown to be effective for reducing, even completely clearing, the redness associated with rosacea.
It works on the receptors in blood vessels in the skin, restricting their dilation.
Your GP may be prepared to prescribe this, though there’s a question mark over whether it can be used long term and, as is the case with the older treatments, even brimonidine is not a cure.
I have one other suggestion. one of my patients finds that when she follows a strict sugar-free diet, her facial redness fades almost completely. But if she has so much as a chocolate biscuit, the redness flares up again the next day.
There’s no evidence to back this up, but I’ve seen that it works for her. Why not try it? I HAVE a metal stent in my right coronary artery and have had a triple bypass. Is it safe to pass through an airport security scanner, which I believe works on a magnetic system?
D. G. Chapman, Orpington, Kent. Your concern is understandable, but I can assure you there is nothing to worry about. Your implant will not be affected by the airport scanner nor will it trigger the alarm.
To explain, a stent is a mesh tube — up to 16mm long and 5mm in diameter — made of a fine metal wire.
Stents are used to open up arteries that have become blocked or narrowed by fatty deposits (or plaques). They are inserted via a minimally invasive procedure called a coronary angioplasty — a
thin, flexible tube with a balloon on the end is inserted into the affected artery.
The balloon is then inflated and a stent is left in its place permanently to hold the artery open. This will help improve blood There flow to the heart muscle. are two main types of stents: bare metal stents and drug- eluting stents. The latter kind, which was developed more recently, is covered in a substance that helps prevent a blood clot forming on the metalwork.
Though stents are used to prevent clots, the presence of a foreign body may lead to clotting in some people and further blockage of the artery.
But regardless of the type of stent used, over time, new cells will grow on the inside and form a new lining that resembles that of the artery, enabling the smooth flow of blood and reducing the chance of clots forming.
Patients treated with coronary angioplasty are given low- dose aspirin and other drugs to further reduce the risk of clots.
As well as angioplasty, you have been treated with a coronary bypass, another technique used to treat blocked arteries.
It involves taking a blood vessel from elsewhere in the body and attaching it to the affected artery to bypass the blockage. The use of angioplasty and bypass is not an either/ or option. Shorter sections of blockage may be better treated with a stent, but longer — or multiple — sections better treated with a bypass.
It’s a decision made jointly by the cardiologist, who performs angioplasty, and heart surgeon, rather than the patient. This will be why you’ve had a combination of treatments.
Stents (whether bare metal or drug- eluting) are made from a non-rusting material that is not attracted to magnets. This is usually a cobalt-chromium alloy. They are also tiny.
In other words, there’s no problem going into an airport security scanner.
It’s the same as if you have a metal zip on your clothes.
