Riehl melanosis - Riehl Melanóza
Riehl Melanóza (Riehl melanosis) je forma kontaktnej dermatitídy, ktorá začína svrbením, erytémom a pigmentáciou, ktorá sa postupne šíri a po dosiahnutí určitého rozsahu sa stáva stacionárnym. Príčinou ochorenia môže byť slnečné žiarenie po použití niektorých parfumov alebo krémov.

Riehl melanosis je často známa ako pigmentová kontaktná dermatitída. Ide o typ kožného ochorenia spôsobeného alergiami, ktoré zvyčajne spúšťa vôňa a iné látky nachádzajúce sa v kozmetických výrobkoch. Napriek tomu, že je Riehl melanosis klasifikovaný ako typ dermatitídy, vykazuje pigmentačné zmeny na koži len s malými príznakmi podráždenia. Je to bežnejšie u ľudí s tmavším odtieňom pleti. Nedávny výskum skúmal účinnosť mid-fluence QSNY 1064-nm laserového ošetrenia pri riešení hlbokej pigmentácie spojenej s Riehl melanosis. Ďalšia štúdia kombinovala rôzne terapie vrátane low-fluence 1064-nm Q-switched Nd: YAG lasera, hydrochinónového krému a perorálnej kyseliny tranexamovej, čo viedlo k významnému zlepšeniu u väčšiny pacientov.
Riehl melanosis (RM), commonly called pigmented contact dermatitis, is considered an acquired form of allergic contact dermatitis, typically to fragrance and other ingredients of cosmetic products. Although it is considered as a dermatitis, it presents clinically with hyperpigmentation over the face and shows pigment incontinence with minimal eczematous changes on histology. The condition is more commonly seen in dark-skinned people, causing an important psychosocial impact. A recent study showing the higher effectiveness of mid-fluence QSNY 1064-nm laser in targetting the deep pigmentation of RM has also been conducted. Another study used a combination of therapies to include low-fluence, 1064-nm, Q-switched Nd: YAG laser, hydroquinone cream, and oral tranexamic acid, with the majority of patients experiencing significant improvement.

Riehl's melanosis je typ ochorenia kože spôsobený kontaktom s určitými alergénmi a vystavením slnečnému žiareniu. Vedie k rýchlej, progresívnej sivohnedej pigmentácii kože, ktorá môže pacientov vo veľkej miere ovplyvniť psychicky aj fyzicky. Zatiaľ čo presná príčina Riehl's melanosis je stále neznáma, existujúci výskum naznačuje silnú súvislosť s expozíciou alergénu. Na liečbu boli vyskúšané tradičné lieky aj laserová terapia, často spolu s použitím bieliacich činidiel aplikovaných na kožu. Laserová terapia, najmä s použitím Q-switched Nd:YAG lasera, ukázala sľubné výsledky pri liečbe Riehl's melanosis. Kombinácia rôznych liečebných postupov vedie k pozitívnym výsledkom.
Riehl's melanosis (RM) is a contact photodermatitis, with fast progressive gray-brown skin pigmentation as the main manifestation, which can seriously affect the psychology and physiology of patients. Currently, although the etiological factors of Riehl's melanosis is still be unknown, the existing literature proves clearly the cause of it is related to the contacting with suspected allergens. For decades, there has been no standard method for the treatment of RM, but with both conventional drug therapy and laser therapy having been attempted. Topical application of bleaching agents is mainly used as an auxiliary treatment modality. The laser treatment modality remains a hot spot, among which Q-switched Nd:YAG laser is well received for RM. Positive outcomes have been achieved by the combined treatment modalities attempted in recent years also achieve positive outcomes.
