ABNOM
☆ U rezultatima Stiftung Warentest-a za 2022. iz Njemačke, zadovoljstvo potrošača ModelDerm-om bilo je samo nešto niže nego s plaćenim telemedicinskim konsultacijama.

Poznato je da Q-switched Nd:YAG laser efikasno tretira Ota nevus i slična stanja. Proveli smo studiju kako bismo vidjeli koliko dobro high-fluence 1064 nm Q-switched Nd:YAG laser djeluje na mongolskim mrljama na neobičnim područjima, a da ne uzrokuje posvjetljenje kože. Proučavali smo 61 pacijenta sa ovim mrljama, pregledavajući ukupno 70 lezija. Polovina lezija je tretirana laserom, dok su druge ostale neliječene radi poređenja. Procijenili smo rezultate pomoću vage i uređaja nazvanog Mexameter® za mjerenje nivoa melanina. Pacijenti su praćeni u prosjeku 14 mjeseci u liječenoj grupi i 18 mjeseci u posmatranoj grupi. Na kraju studije, otkrili smo značajne razlike u rezultatima skale i nivoima melanina između liječenih i neliječenih grupa, pri čemu je grupa tretirana laserom pokazala bolje rezultate. High-fluence Q-switched Nd:YAG laser, bez izazivanja posvjetljenja kože, pokazao se djelotvornim i sigurnim za tretiranje ovih neobičnih mongolskih mrlja.
The Q-switched Nd:YAG laser is known to effectively treat nevus of Ota and similar conditions. We conducted a study to see how well a high-fluence 1064 nm Q-switched Nd:YAG laser worked on Mongolian spots in unusual areas, without causing the skin to lighten. We studied 61 patients with these spots, examining a total of 70 lesions. Half of lesions were treated with the laser, while others were left untreated for comparison. We evaluated the results using a scale and a device called a Mexameter® to measure melanin levels. Patients were followed up for an average of 14 months in the treatment group and 18 months in the observation group. At the end of the study, we found significant differences in the scale scores and melanin levels between the treated and untreated groups, with the laser-treated group showing better outcomes. The high-fluence Q-switched Nd:YAG laser, without causing skin lightening, proved effective and safe for treating these unusual Mongolian spots.

Proučili smo efikasnost i sigurnost upotrebe specifičnog laserskog tretmana za ABNOM i pogledali koji faktori mogu uticati na to kako dobro djeluje. Pregledali smo 110 pacijenata koji su imali ABNOM i dobili između dva i devet laserskih tretmana. Otkrili smo da je tretman djelovao bolje što je duže trajao, ali ne tako dobro kod starijih pacijenata. Također je djelovao bolje kod pacijenata sa svjetlijom kožom (tip III) i manjim zahvaćenim područjima (manje od 10 cm2) . Imajući melazmu zajedno sa ABNOM tretman je bio manje efikasan. Čini se da boja ili broj zahvaćenih područja nisu napravili razliku. Oko 10% pacijenata dobilo je tamnije mrlje nakon tretmana. Rano višestruko liječenje dalo je dobre rezultate. Kod starijih pacijenata sa tamnijom kožom i tamnijim mrljama veća je vjerovatnoća da će nakon tretmana dobiti tamnije mrlje. Za pacijente sa ABNOM i melazmom, bolje je koristiti laser niže energije kako bi se izbjeglo pogoršanje melazme.
To evaluate the efficacy and safety of 1064-nm Q-switched Nd:YAG laser (QSNYL) therapy for ABNOM and to identify the factors influencing the outcome. A total of 110 patients with ABNOM were retrospectively evaluated and received two-to-nine treatment sessions. The curative effect was positively correlated with the treatment time and negatively correlated with the increasing age at first treatment (p < 0.05). The curative effect was better in patients with skin type III than those with type IV ( p < 0.05) and in patients with a lesion area of less than 10 cm2 than those with a larger affected area (p < 0.05). Additionally, the treatment effect was poorer in patients with concomitant melasma (p < 0.05). The treatment effect was not significantly correlated with the lesion color or number of affected sites (p > 0.05). Eleven patients (10%) developed postinflammatory hyperpigmentation (PIH). Early and repeated QSNYL therapy achieved satisfactory results for ABNOM. The risk of PIH after laser treatment is highest among patients with older age, darker lesion color, and darker skin color. For patients with ABNOM with concurrent melasma, low-energy laser therapy is recommended to reduce the risk of melasma aggravation.

○ Treatment
Sredstva za izbjeljivanje rijetko pomažu. Za razliku od melazme, ABNOM se može poboljšati laserskim tretmanom i ostaviti da se ukloni bez ponavljanja. Laserski tretman se može izvesti 10 do 20 puta za liječenje ABNOM-a.
