Rosacea (IPA: /rəʊˈzeɪʃə/) is a common but often misunderstood condition that is estimated to affect over 45 million people worldwide. It affects white-skinned people of mostly north-western European descent, and has been nicknamed the 'curse of the Celts' by some in Ireland. It begins as erythema (flushing and redness) on the central face and across the cheeks, nose, or forehead but can also less commonly affect the neck and chest. As rosacea progresses, other symptoms can develop such as semi-permanent erythema, telangiectasia (dilation of superficial blood vessels on the face), red domed papules (small bumps) and pustules, red gritty eyes, burning and stinging sensations, and in some advanced cases, a red lobulated nose (rhinophyma). The disorder can be confused and co-exist with acne vulgaris and/or seborrheic dermatitis. Rosacea affects both sexes, but is almost three times more common in women, and has a peak age of onset between 30 and 60. The presence of rash on the scalp or ears suggests a different or co-existing diagnosis, as rosacea is primarily a facial diagnosis. Wikipedia does not have an article with this exact name. ...

Subtypes and symptoms

There are four identified rosacea subtypes^[1] and patients may have more than one subtype present.

There have been other descriptive terms applied to presentations of rosacea, but these are not formally accepted as subtyes of rosacea:^[3] Erythema is an abnormal redness of the skin caused by capillary congestion. ...

Causes

Richard L. Gallo and colleagues recently noticed that patients with rosacea had elevated levels of the peptide cathelicidin and elevated levels of stratum corneum tryptic enzymes (SCTEs). Antibiotics have been used in the past to treat rosacea, but antibiotics may only work because they inhibit some SCTEs. See the August 5, 2007 issue of Nature Medicine for details. Cathelicidin is an antimicrobial peptide produced in macrophages triggered by bacteria, viruses, and fungi, when the hormone 1,25-D is present. ...

Rosacea has a hereditary component and those that are fair-skinned of European or Celtic ancestry have a higher genetic predisposition to developing it. Women are more commonly affected but when men develop rosacea it tends to be more severe. People of all ages can get rosacea but there is a higher instance in the 30-50 age group. The first signs of rosacea are said to be persisting redness due to exercise, changes in temperature, and cleansing.

Triggers that cause episodes of flushing and blushing play a part in the development of rosacea. Exposure to temperature extremes can cause the face to become flushed as well as strenuous exercise, heat from sunlight, severe sunburn, stress, anxiety, cold wind, moving to a warm or hot environment from a cold one such as heated shops and offices during the winter. There are also some foods and drinks that can trigger flushing, these include alcohol, foods and beverages containing caffeine (especially, hot tea and coffee), foods high in histamines and spicy food, as well as fruits containing high levels of antioxidants, such as red grapes. This article does not cite any references or sources. ... Caffeine is a xanthine alkaloid compound that acts as a stimulant in humans. ... This article or section does not cite any references or sources. ... Spices are strongly flavored or aromatic parts of plants used in small quantities in food as a preservative, or flavouring in cooking. ...

Certain medications and topical irritants can quickly progress rosacea. If redness persists after using a treatment then it should be stopped immediately. Some acne and wrinkle treatments that have been reported to cause rosacea include microdermabrasion, chemical peels, high dosages of isotretinoin, benzoyl peroxide and tretinoin. Steroid induced rosacea is the term given to rosacea caused by the use of topical or nasal steroids. These steroids are often prescribed for seborrheic dermatitis. Dosage should be slowly decreased and not immediately stopped to avoid a flare up. Isotretinoin (INN) (IPA: ) is a medication used for the treatment of severe acne. ... Tretinoin is the acid form of vitamin A and so also known as all-trans retinoic acid or ATRA. It is a drug commonly used to treat acne vulgaris and keratosis pilaris. ... This article is about the chemical family of steroids. ...

Studies of rosacea and demodex mites have revealed that some people with rosacea have increased numbers of the mite, especially those with steroid induced rosacea.^[11] When large numbers are present they may play a role along with other triggers. On other occasions Demodicidosis (Mange) is a separate condition that may have "rosacea-like" appearances.^[12] Species Demodex brevis Demodex bovis Demodex canis Demodex caprae Demodex cati Demodex equi Demodex folliculorum Demodex ovis Demodex phyloides The demodex mites form a genus of tiny parasitic mites which live in or near hair follicles of mammals. ... Mange (from Middle English manjeue, from Old French manjue, from mangier, meaning to eat)[1] is a parasitic infestation of the skin of animals. ...

It has also been suggested that rosacea might be a neurological disorder resulting from hypersensitization of sensory neurons following activation of the plasma kallikrein-kinin system by exposure to intestinal bacteria in the digestive tract.^[13] The kinin-kallikrein system or simply kinin system is a poorly delineated system of blood proteins that plays a role in inflammation, blood pressure control, coagulation and pain. ... Gut flora, or intestinal bacteria, are the bacteria that normally live in the digestive tract and perform a number of useful functions involving digestion for their hosts. ...

Treatments

Treating rosacea varies from patient to patient depending on severity and subtypes. Dermatologists are recommended to take a subtype-directed approach to treating rosacea patients.^[14]

Trigger avoidance can help reduce the onset of rosacea but alone will not normally cause remission for all but mild cases. The National Rosacea Society recommends that a diary be kept to help identify and reduce triggers.

It is important to have a gentle skin cleansing regimen using non-irritating cleansers. Protection from the sun is important and daily use of a sunscreen of at least SPF 15 containing a physical blocker such as zinc oxide or titanium dioxide is advised although chemical sunscreens, if non-irritating to the skin, are also an option. Sunscreen (also known as sunblock, suntan lotion) is a lotion, spray or other topical product that helps protect the skin from the suns ultraviolet (UV) radiation, and which reduces sunburn and other skin damage, with the goal lowering your risk of skin cancer. ... Zinc oxide is a chemical compound with formula ZnO. It is nearly insoluble in water but soluble in acids or alkalis. ... Titanium dioxide, also known as titanium(IV) oxide or titania, is the naturally occurring oxide of titanium, chemical formula TiO2. ...

Oral tetracycline antibiotics (tetracycline, doxycycline, minocycline) and topical antibiotics such as metronidazole are usually the first line of defense prescribed by doctors to relieve papules, pustules, inflammation and some redness.^[15] Topical Azelaic acid such as Finacea maya help reduce inflammation. Oral antibiotics may help to relieve symptoms of ocular rosacea. If papules and pustules persist, then sometimes isotretinoin can be prescribed.^[16] Isotretinoin has many side effects and is normally used to treat severe acne but in low dosages is proven to be effective against papulopustular and phymatous rosacea. This article deals with the group of antibiotics known as the Tetracyclines . ... Tetracycline (INN) (IPA: ) is a broad-spectrum antibiotic produced by the streptomyces bacterium, indicated for use against many bacterial infections. ... Doxycycline (INN) (IPA: ) is a member of the tetracycline antibiotics group and is commonly used to treat a variety of infections. ... Minocycline hydrochloride, also known as minocycline, is a member of the broad spectrum tetracycline antibiotics, and has a broader spectrum than the other members. ... Metronidazole (INN) (IPA: ) is a nitroimidazole anti-infective drug used mainly in the treatment of infections caused by susceptible organisms, particularly anaerobic bacteria and protozoa. ... Isotretinoin (INN) (IPA: ) is a medication used for the treatment of severe acne. ...

The treatment of flushing and blushing has been attempted by means of the centrally acting α-2 agonist clonidine, but there is no evidence whatsoever that this is of any benefit. The same is true of the beta-blockers nadolol and propanolol. If flushing occurs with red wine consumption, then complete avoidance helps. There is no evidence at all that antihistamines are of any benefit in rosacea. Clonidine is a direct-acting adrenergic agonist prescribed historically as an anti-hypertensive agent. ...

People who develop infections of the eyelids must practice frequent eyelid hygiene. Daily scrubbing the eyelids gently with diluted baby shampoo or an over-the-counter eyelid cleaner and applying warm (but not hot) compresses several times a day is recommended.

Dermatological vascular laser (single wavelength) or Intense Pulsed Light (broad spectrum) machines offer one of the best treatments for rosacea, in particular the erythema (redness) of the skin.^[17] They use light to penetrate the epidermis to target the capillaries in the dermis layer of the skin. The light is absorbed by oxy-hemoglobin which heat up causing the capillary walls to heat up to 70ºC, damaging them, causing them to be absorbed by the body's natural defence mechanism. For other uses, see Laser (disambiguation). ... A human arm, four hours after IPL treatment. ...

The dermis is a layer of skin beneath the epidermis that consists of connective tissue and cushions the body from stress and strain. ... Structure of hemoglobin. ...

CO₂ lasers can be used to remove excess tissue caused by phymatous rosacea. CO₂ lasers emit a wavelength that is absorbed directly by the skin. The laser beam can be focused into a thin beam and used as a scalpel or defocused and used to vaporise tissue. Low level light therapies have also been used to treat rosacea. One alternative skin treatment, fashionable in the Victorian and Edwardian eras, was Sulphur. Recently Sulphur has re-gained some credibility as a safe alternative to steroids and coal tar.
