સૂર્યકિરણોમાં Cheilitis શું છે (AC)?


શું છે સૂર્યકિરણોમાં cheilitis
Actinic cheilitis manifests a diffuse or patchy dryness and variable thickening of the vermillion of the lower lip. The prevalent form of actinic cheilitis is due to chronic sun exposure. It is also called actinic cheilosis, solar cheilitis and sometimes, actinic cheilitis with histological atypia.
AC almost always affects the lower lips and only rarely the upper lip, probably because of the lower lip more exposed to the sun. In the unusual cases reported where it affects the upper lip, this may be due to upper lip prominent commissures (corners of the mouth are not usually involved.
Affected individuals may experience symptoms such as dry sensation and cracking of the lips. It is usually painless and persistent.
The appearance is variable. White lesion indicates hyperkeratosis Red, erosive or ulcerative lesions indicate loss of epithelium and inflammation. Early, the acute lesion may be erythematous (લાલ) and edematous (swollen) months and years of sun exposure, પાઠ ક્રોનિક બની જાય છે અને તે રાખોડી-સફેદથી હોઈ શકે છે અને શુષ્ક દેખાશે, ભીંગડાંવાળું કે જેવું અને કરચલીવાળી.

AC may occur with skin lesions of actinic keratosis or skin cancer else particularly on the head he neck since these are the most sun-exposed areas. Rarely it may represent a genetic susceptibility to light damage (e.g., xeroderma pigmentosum or actinic prurigo).

કારણો
AC is created by chronic and excessive exposure to ultraviolet radiation in sunlight Risk factors include:

Outdoor lifestyle: e.g., farmers, fishers, windsurfers, mountaineers, golfers. This has given rise to synonyms for this condition such as sailor’s lip and farmer’s lip. There is a prevalence of agricultural workers in a semi-arid region of Brazil who report AC in some areas as high as 16.7%
Light skin complexion: the condition typically affects people with lighter skin tones. Partially Caucasian living in tropical regions. IN one report, 96% or person with AC had phenotype 11 according to the Fitzpatrick scale.
Age: AC commonly affects older individuals, and rarely those under 45 વર્ષ જૂના.
Gender. The condition affects males more commonly than females; Sometimes this ratio is reported as high as 10:1

Actinic cheilitis also describes lip improvement in actinic prurigo, a rare form of photosensitivity.

Who gets actinic cheilitis
Actinic cheilitis largely influences adults with fair skin who live in tropical or subtropical areas, especially outdoors workes. They frequently recall having sunburned lips in earlier years. They may also have actinic keratoses on other sun-exposed sites of the scalp, ears, face, and hands.
Actinic cheilitis is three times more in males than in females.
What causes actinic cheilitis?
Actinic cheilitis results from chronic exposure of the lower lip to solar ultraviolet radiation It is more vulnerable than encompassing skin because mucosal epithelium is thinner and less pigmented than the epidermis.
What are the clinical symptoms of actinic cheilitis?
Actinic cheilitis most commonly affects the lower lip (90%), and causes:

  1. Skin Dryness
  2. Thinned fragile skin
  3. Thickened, scaly papules and plaques (actinic keratoses)
  4. Less common symptoms of actinic cheilitis include;
  5. લાલાશ
  6. Soreness
  7. સોજો
  8. Fissuring, focal ulceration, and cutting
  9. White thickened patches (leukokeratosis)
  10. Loss of demarcation/Marks and lipline between the vermillion border of the lip and its adjoining skin
  11. Discoloured skin with pale or yellow area
  12. IIf applying lipstick, which tends tobleed into the surrounding lines
  13. Prominent folds and lip lines.

What is the complication of actinic cheilitis?
Actinic cheilitis is a pre-malignant condition. It predisposes to:

Intraepidermal carinoma (Bowen disease or squamoous cell carinoma in situ) .
Invasive squamous cell carcinoma
Cancer of the lip is more in smokers than in non-smokers. Other factors involve oncogenic human papillomavirus (wart virus), immunosuppression and alcohol abuse.

Invasive squamous cell carcinoma should be suspected if the lip is focally tender, or a persistent ulcer or enlarging nodule develops.

How is actinic cheilitis diagnosed?
Actinic cheilitis is generally diagnosed clinically; a skin biopsy may require fluorouracil if skin cancer or an inflammatory cause of cheilitis is presumed.

The pathological characteristics of actinic cheilitis are mutable thickening or atrophy of the lip, partial thickness epidermal dysplasia, solar elastosis and inflammation in the dermis of the skin.

What is the therapy and treatment options for actinic cheilitis?
Smoking for an extended period, and lifelong, year-round, daily sun protection are essential.
Limit sun exposure
Wear a hat with a wide brim
Apply sunscreen-containing lip balm frequently

Men can consider growing a mustache.
Topical therapies for actinic cheilitis are unapproved. They include:

Photodynamic therapy -Photodynamic therapy (PDT) is a treatment that uses a drug, referred to a photosensitizer or photosensitizing agent, and a distinct type of light. When photosensitizers are revealed to a specific wavelength of light, they produce a form of oxygen that kills nearby cells.

Each photosensitizer is activated by light of a specific wavelength. This wavelength defines how far the light can travel into the body. આમ, physicians use specific photosensitizers and wavelengths of light to treat different areas of the body with PDT.

Imiquimod cream (Aldara) is an immune response modifier that has been analyzed for the treatment of actinic cheilitis. It develops an immune response in the skin leading to apoptosis (death) or the tumor cells. It produces the epidermis to be invaded by macrophages, which leads to epidermal erosion. T-cells are also stimulated as a consequence of imiquimod treatment. Imiquimod seems to promote animmune memorythat decreases the recurrence of lesions; There is minimal scarring. Complete clearance has been shown in up to 45% of patients with actinic keratoses. જોકે, the dose and duration of therapy as well as the long-term efficacy, still need to be established for the treatment of actinic cheilitis.

5-fluorouracil cream Topical 5-fluorotic (5-FU, Efudex, Carac) has been shown to be an efficient therapy for diffuse, but minor actinic cheilitis, 5-fluorouracil works by blocking DNA synthesis. Cells that are quickly growing require additional DNA, so they accumulate more 5-fluorouracil, ending in their death. Healthy skin is much less affected. The treatment normally takes 2-4 weeks based on the response. The expected response includes a swelling phase, followed by redness, oozing, સળગતો, and finally erosion. Treatment is discontinued when ulceration and crusting develop. There is minimum scarring Complete clearance has been reported in about 50% of patients.
