Riehl melanosis - Riehl Melanozė
Riehl melanozė (Riehl melanosis) yra kontaktinio dermatito forma, kuri prasideda niežuliu, eritėma ir palaipsniui plintančia pigmentacija; kai pasiekia tam tikrą ribą, ji sustoja. Saules šviesos poveikis po kai kurių kvepalų ar kremų naudojimo gali sukelti ligą.
☆ 2022 m. Stiftung Warentest iš Vokietijos rezultatai rodo, kad vartotojų pasitenkinimas ModelDerm buvo tik šiek tiek mažesnis nei mokamų nuotolinės medicinos konsultacijų.

ReferencesRiehl melanosis, dažnai vadinama pigmentiniu kontaktiniu dermatitu, yra odos būklė, kurią sukelia alergija – dažniausiai kvapų ir kitų kosmetikos gaminiuose esančių medžiagų. Nors ši liga klasifikuojama kaip dermatito tipas, Riehl melanosis pasireiškia odos pigmentacijos pokyčiais ir tik nedideliais sudirginimo požymiais. Ji dažniau pasireiškia žmonėms su tamsesniu odos tonu. Naujausi tyrimai įvertino vidutinės intensyvumo (mid‑fluence) Q‑switched Nd:YAG 1064 nm lazerio veiksmingumą kovojant su gilios pigmentacijos, susijusios su Riehl melanosis, atveju. Kitame tyrime derinami skirtingi gydymo metodai – žemos intensyvumo (low‑fluence) 1064 nm Q‑switched Nd:YAG lazeris, hidrochinono kremas ir geriamasis traneksamo rūgšties preparatas – ir daugumai pacientų pasireikš reikšmingas pagerėjimas.
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 yra odos būklė, kurią sukelia sąlytis su tam tikrais alergenais ir saulės spinduliai. Tai lemia greitą, progresuojančią pilkai rudos odos pigmentaciją, kuri gali labai paveikti pacientus tiek psichologiškai, tiek fiziškai. Nors tiksli Riehl's melanosis priežastis vis dar nežinoma, esami tyrimai rodo tvirtą ryšį su alergenais. Gydymui buvo išbandyti tiek konvenciniai vaistai, tiek lazerio terapija, dažnai kartu su odos balinimo priemonėmis. Lazerio terapija, ypač naudojant Q‑switched Nd:YAG lazerį, parodė daug žadančių rezultatų gydant Riehl's melanosis. Skirtingų gydymo metodų derinimas davė teigiamų rezultatų.
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.
