ABNOM
☆ Nos resultados do Stiftung Warentest de 2022 da Alemanha, a satisfação do consumidor com o ModelDerm foi apenas ligeiramente inferior do que com as consultas pagas de telemedicina.

O laser Q-switched Nd:YAG é conhecido por tratar eficazmente o nevo de Ota e condições semelhantes. Realizamos um estudo para ver quão bem um laser high-fluence 1064 nm Q-switched Nd:YAG funcionou em manchas da Mongólia em áreas incomuns, sem causar clareamento da pele. Estudamos 61 pacientes com essas manchas, examinando um total de 70 lesões. Metade das lesões foi tratada com laser, enquanto outras ficaram sem tratamento para comparação. Avaliamos os resultados usando uma balança e um aparelho chamado Mexameter® para medir os níveis de melanina. Os pacientes foram acompanhados por uma média de 14 meses no grupo de tratamento e 18 meses no grupo de observação. No final do estudo, encontramos diferenças significativas nas pontuações da escala e nos níveis de melanina entre os grupos tratados e não tratados, com o grupo tratado com laser apresentando melhores resultados. O laser high-fluence Q-switched Nd:YAG , sem causar clareamento da pele, se mostrou eficaz e seguro no tratamento dessas manchas incomuns da Mongólia.
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.

Estudamos a eficácia e a segurança do uso de um tratamento a laser específico para ABNOM e analisamos quais fatores podem afetar seu funcionamento. Analisamos 110 pacientes que fizeram ABNOM e receberam entre dois e nove tratamentos a laser. Descobrimos que o tratamento funcionou melhor quanto mais tempo foi realizado, mas não tão bem em pacientes mais velhos. Também funcionou melhor em pacientes com pele mais clara (tipo III) e áreas afetadas menores (menos de 10 cm2) . Ter melasma junto com ABNOM tornou o tratamento menos eficaz. A cor ou o número de áreas afetadas não pareceram fazer diferença. Cerca de 10% dos pacientes apresentaram manchas mais escuras após o tratamento. O tratamento múltiplo precoce deu bons resultados. Pacientes mais velhos com pele mais escura e manchas mais escuras têm maior probabilidade de apresentar manchas mais escuras após o tratamento. Para pacientes com ABNOM e melasma, é melhor usar um laser de menor energia para evitar piorar o melasma.
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.

○ Tratamento
Os agentes clareadores raramente ajudam. Ao contrário do melasma, o ABNOM pode ser melhorado com tratamento a laser e deixado para ser removido sem recorrência. O tratamento a laser pode ser realizado de 10 a 20 vezes para tratar ABNOM.
