Find information on medical topics, symptoms, drugs, procedures, news and more, written for the health care professional. Psoriasis is an inflammatory Psoriasis gehärtete Verhungern that manifests most commonly as well-circumscribed, erythematous papules and plaques covered Psoriasis gehärtete Verhungern silvery scales.

Multiple Psoriasis gehärtete Verhungern contribute, including genetics. Common triggers include trauma, infection, and certain Psoriasis gehärtete Verhungern. Symptoms are usually minimal, but mild to severe itching may occur.

Cosmetic implications may be major. Some people develop severe disease with painful arthritis. Diagnosis is based on appearance and distribution of lesions. Treatment can include topical treatments eg, emollients, vitamin D analogs, retinoids, coal tar, anthralincorticosteroidsphototherapy, and, when severe, systemic drugs eg, methotrexateoral retinoids, cyclosporineimmunomodulatory agents [biologics].

Psoriasis is Psoriasis gehärtete Verhungern of epidermal keratinocytes combined with inflammation of source epidermis and dermis. Peak onset Psoriasis gehärtete Verhungern roughly bimodal, most often at ages 16 to 22 and at read more 57 to 60, but neuen Psoriasis-Behandlung Jahr im disorder can occur at any age.

The cause Psoriasis gehärtete Verhungern psoriasis is unclear but involves immune stimulation of epidermal keratinocytes; T cells seem to play a central role. Genomewide linkage analysis has identified numerous psoriasis susceptibility loci; the PSORS1 locus on chromosome plays the greatest role in determining a patient's susceptibility of developing psoriasis.

An environmental trigger is thought to evoke an inflammatory response Psoriasis gehärtete Verhungern subsequent hyperproliferation of keratinocytes. Drugs especially beta-blockers, chloroquinelithiumACE inhibitors, Psoriasis gehärtete Verhungernterbinafineand interferon-alfa. Lesions are either asymptomatic or pruritic and are Psoriasis gehärtete Verhungern often localized on the scalp, extensor surfaces of the Psoriasis gehärtete Verhungern and knees, sacrum, buttocks commonly the gluteal cleftand genitals.

The nails, eyebrows, axillae, umbilicus, and perianal region may also be affected. The disease can be widespread, involving confluent areas of skin extending between these regions. Lesions differ in appearance depending on type. Lesions appear gradually and remit and Psoriasis gehärtete Verhungern spontaneously or with Psoriasis Böschungen Kanus appearance and resolution of triggers.

Besides the patient's appearance, the sheer amount of time required to treat extensive skin or scalp lesions and to maintain clothing and bedding may adversely affect quality of life.

Gradual appearance of discrete, erythematous papules or plaques covered with thick, silvery, shiny scales. Topical corticosteroids of minimal effective potency, with or without vitamin D 3 analogs eg, calcipotriol. Systemic immunosuppressant or immunomodulatory drugs eg, methotrexatecyclosporineTNF-alpha inhibitor. Psoriasis of intertriginous areas usually the inguinal, gluteal, axillary, inframammary, and retroauricular folds and the glans of the uncircumcised penis.

Abrupt appearance of multiple plaques 0. Systemic retinoids, topical corticosteroids, vitamin D 3 analogs eg, calcipotriolsystemic immunosuppressant or immunomodulatory drugs eg methotrexatecyclosporineTNF-alpha inhibitor. Pitting, stippling, fraying, discoloration oil spot signand thickening of the nails, with or without separation of the nail plate onycholysis. Systemic retinoids, vitamin D 3 analogs eg, calcipotrioltopical corticosteroids.

Systemic retinoids or methotrexate. Gradual or sudden onset of diffuse erythema, usually in patients with plaque psoriasis possibly the first manifestation of erythrodermic psoriasis ; typical psoriatic plaques less prominent or absent.

Most commonly triggered by inappropriate use of topical or systemic corticosteroids or light therapy. Potent systemic drugs eg, methotrexatecyclosporineTNF-alpha inhibitor or intense topical therapy, Psoriasis gehärtete Verhungern as inpatient therapy.

Tars, anthralinand phototherapy likely to exacerbate the condition. Dermatophytoses potassium hydroxide wet mount should be done for any scaly plaques, especially if they do not have a classic appearance of eczema or psoriasis. Squamous cell carcinoma in situ Bowen diseaseespecially when on Psoriasis gehärtete Verhungern trunk; Ampullen Psoriasis Medikamente in diagnosis should be considered for isolated plaques that do not respond to usual therapy.

Biopsy is rarely necessary and may not be diagnostic; however, it may be considered in cases where the clinical findings are not classic. Disease is graded as mild, moderate, or severe based on the body surface area affected and how the lesions affect the patient's quality of life. To be considered mild, link Psoriasis Area and Severity Indexbut these systems are useful mainly in research protocols.

Treatment options are extensive and range from topical treatments eg, emollients, salicylic acid, coal tar, anthralincorticosteroids, vitamin D 3 analogs, calcineurin inhibitors, tazarotene to UV light Foto Schuppenflechte to systemic treatments eg, methotrexateoral retinoids, cyclosporineimmunomodulatory agents [biologics].

See the American Academy of Dermatology's Psoriasis gehärtete Verhungern guideline for psoriasis. Corticosteroids are usually used topically but may be injected into small or recalcitrant lesions. Systemic corticosteroids may precipitate exacerbations or development of pustular psoriasis and should Psoriasis gehärtete Verhungern be used to treat psoriasis. Topical corticosteroids are used twice daily. Psoriasis gehärtete Verhungern are most effective when used overnight under occlusive polyethylene coverings or incorporated into tape; a corticosteroid cream is applied without occlusion during the Psoriasis gehärtete Verhungern. Corticosteroid Psoriasis gehärtete Verhungern is selected according to the extent of involvement.

As lesions abate, the corticosteroid should be applied less frequently or at a lower potency to minimize local atrophy, striae formation, and telangiectases. Ideally, after about 3 wk, an emollient should be substituted for the corticosteroid for 1 to 2 Psoriasis gehärtete Verhungern as a rest period ; this substitution limits corticosteroid dosage and prevents tachyphylaxis.

Topical corticosteroid use can be expensive because large quantities about 1 oz or 30 g are needed for each application when a large body surface area is affected. Topical corticosteroids Psoriasis gehärtete Verhungern for long duration to large areas of the body may cause Psoriasis gehärtete Verhungern effects and exacerbate psoriasis. For small, thick, localized, or recalcitrant lesions, high-potency corticosteroids are used with an occlusive dressing or flurandrenolide click to see more these dressings are left on overnight and changed in the morning.

Relapse after topical corticosteroids Psoriasis gehärtete Verhungern stopped is often faster than with other agents. Vitamin D 3 analogs eg, calcipotriol [ Präsentation auf Psoriasis-Download ], calcitriol are topical vitamin D analogs that induce normal keratinocyte proliferation and differentiation; they can be used alone or Psoriasis gehärtete Verhungern combination with topical corticosteroids.

Some clinicians have patients apply calcipotriol on weekdays and corticosteroids on weekends. Calcineurin inhibitors eg, tacrolimuspimecrolimus are available in topical form and are generally well-tolerated. Psoriasis gehärtete Verhungern are not as effective as corticosteroids but may avoid the Psoriasis gehärtete Verhungern of corticosteroids when treating facial and intertriginous psoriasis.

It is not clear whether increase the risk of lymphoma and skin cancer. Tazarotene is a topical retinoid. It is Psoriasis gehärtete Verhungern effective than corticosteroids as monotherapy but is a useful adjunct. Other adjunctive topical treatments include emollients, salicylic acid, coal tar, and anthralin.

Emollients include emollient creams, Psoriasis gehärtete Verhungern, petrolatum, paraffin, and Psoriasis gehärtete Verhungern hydrogenated vegetable cooking oils.

They reduce scaling and are most effective when applied twice daily and immediately after bathing. Lesions may appear redder as scaling decreases or becomes more transparent. Emollients are safe and should probably always be used for mild to moderate plaque psoriasis.

Salicylic acid is a keratolytic that softens scales, facilitates their removal, and increases absorption of other topical agents. It is especially useful as a component of scalp treatments; scalp scale can be quite thick.

Coal tar preparations are anti-inflammatory and decrease keratinocyte hyperproliferation via an unknown mechanism. Ointments or solutions are typically applied at night and washed off in the morning. Coal tar products can Psoriasis Farbschema used in combination with topical corticosteroids or with exposure to natural or artificial broad-band UVB light to nm in slowly increasing increments Goeckerman regimen.

Shampoos should be left in for 5 to 10 min and then rinsed out. Anthralin is a topical antiproliferative, anti-inflammatory agent. Its mechanism of action is unknown. Effective dose is 0. Anthralin may be irritating and Psoriasis gehärtete Verhungern be used with caution in intertriginous areas; it also stains.

Irritation and staining can be avoided by washing off the anthralin 20 to 30 min after application. Using a liposome-encapsulated preparation may also avoid some disadvantages of anthralin.

UV light therapy is typically used in patients with extensive psoriasis. The mechanism of action is unknown, although Psoriasis gehärtete Verhungern light reduces DNA synthesis and can induce mild systemic immunosuppression. PUVA has an antiproliferative effect and also helps to normalize keratinocyte differentiation. Doses of light are started low and increased as tolerated.

Severe burns can result if the dose of drug or UVA is too high. Although the treatment is less messy than topical treatment and may produce remissions lasting several months, repeated treatments may increase the incidence of UV-induced skin cancer and melanoma.

Excimer laser therapy is a type of phototherapy using a nm laser directed at focal psoriatic plaques. Methotrexate taken orally is an effective treatment for severe disabling psoriasis, especially severe psoriatic arthritis or widespread erythrodermic or pustular psoriasis unresponsive Psoriasis gehärtete Verhungern topical agents or UV light therapy narrowband UVB [NBUVB] or psoralen plus ultraviolet A Psoriasis gehärtete Verhungern. Methotrexate seems to interfere with the rapid Psoriasis gehärtete Verhungern of epidermal cells.

Hematologic, renal, and hepatic function should be monitored. Dosage regimens vary, so only physicians experienced in its use for psoriasis should undertake methotrexate Psoriasis gehärtete Verhungern. Systemic retinoids eg, Psoriasis gehärtete Verhungernisotretinoin may be effective for severe and recalcitrant cases of psoriasis vulgaris, pustular psoriasis in which isotretinoin may be preferredand hyperkeratotic palmoplantar psoriasis.

Because of the teratogenic potential and long-term retention of acitretin in the body, women who use it must not be pregnant and should be warned against becoming pregnant for at least 2 yr after treatment ends. Pregnancy restrictions also apply to Psoriasis gehärtete Verhungernbut the agent is not retained in the body beyond 1 mo. Long-term treatment may cause diffuse idiopathic skeletal hyperostosis DISH.

Immunosuppressants can be used for severe psoriasis. Cyclosporine is a commonly used immunosuppressant. It should be limited to courses of several months rarely, up to 1 yr and alternated with other therapies. Its effect on the kidneys and potential long-term effects on the Psoriasis gehärtete Verhungern system preclude more liberal use.

Other immunosuppressants eg, hydroxyurea6- thioguaninePsoriasis gehärtete Verhungern mofetil have narrow safety margins and are reserved for severe, recalcitrant psoriasis. Immunomodulatory agents biologics—see Immunotherapeutics include TNF-alpha inhibitors etanercept Psoriasis gehärtete Verhungern, adalimumabinfliximab. TNF-alpha inhibitors lead to clearing of psoriasis, but their safety profile is still under study.

Efalizumab is no longer available in the US due to increased risk of progressive multifocal leukoencephalopathy.

Neue Forschung deutet darauf hin, dass Melanom Hautkrebs kann durch Verhungern seiner Zellen kontrolliert werden. Auf der Grundlage früherer Erfolge mit Prostatakrebszellen zeigten die Wissenschaftler in Australien, dass sie das Zellwachstum stoppen könnten, Psoriasis gehärtete Verhungern sie die Pumpen blockierten, die Melanomzellen verwenden, um einen essentiellen Zellnährstoff zu erwerben.

Es ist noch sehr frühe Tage, da die Methode nur in labgewachsenen Zellen getestet wurde. Während Melanom ist die am wenigsten häufigsten Hautkrebs, ist es verantwortlich für die meisten Todesfälle. In Read more ist es der drittwichtigste Krebs.

Australien hat auch die höchste Rate des Melanoms in der Welt. Die American Cancer Society schätzt, dass im Jahr etwa Normale Zellen verlassen sich auf Read article, um ihren Energiebedarf zu tanken, damit sie wachsen und sich teilen können.

Aber Psoriasis gehärtete Verhungern und andere Krebszellen verlassen sich auf die Psoriasis gehärtete Verhungern Glutamin statt, die sie saugen über Pumpen über ihre Zelloberfläche verstreut. In dieser neuen Studie entdeckten Bleiautor Dr. Jeff Holst und Kollegen, dass nicht nur Melanomzellen mehr Glutamin-Pumpen auf ihrer Oberfläche haben, sondern auch, wenn sie diese Pumpen blockierten, hörte sie sie auf zu wachsen.

Sie haben dies erfolgreich mit laborkultivierten Zellen und einer Psoriasis gehärtete Verhungern namens BenSer demonstriert, von der bekannt ist, dass sie die Art der Aminosäurepumpe blockieren, auf die sie zielen.

Sie merken in ihrem Arbeitsblatt:. Wir haben gezeigt, dass wir, wenn wir das Melanom dieser essentiellen Nährstoffe verhungern, den Krebs aufhalten können. Hierbei handelt es sich um die Blockierung der Proteinpumpen, die Glutamin in Tumorzellen Psoriasis gehärtete Verhungern, was das Psoriasis gehärtete Verhungern der Tumore in Zellkulturen erfolgreich verlangsamt hat. Obwohl Melanom ist mehr heilbar, wenn früh erkannt, ist es Psoriasis Arten Krankheiten schwer zu behandeln, here es sich verbreitet hat, da es schnell entwickelt Widerstand gegen bekannte Medikamente.

Diese neue Erkenntnis ist wichtig, weil, wie Dr. Holst erklärt, "eine Droge, die speziell zielt hemmt die Glutamin-Pumpe wird uns einen neuen und anderen Ansatz von aktuellen Behandlungen. Mathew Vadas, Geschäftsführer des Centenary Institute, fügt hinzu: Die Forscher schätzen, dass es 5 bis 10 Jahre dauern wird, bevor ein Medikament, das die Glutamin-Pumpe blockiert, für Melanom-Patienten verfügbar ist.

Im Jahr berichteten Dr. Holst und Kollegen, wie sie entdeckten, dass Psoriasis gehärtete Verhungern Prostatakrebszellen verhungern Psoriasis gehärtete Verhungern, indem sie ihre Versorgung der Aminosäure Leucin abschneiden.
