ABNOM
☆ Sa 2022 na mga resulta ng Stiftung Warentest mula sa Germany, ang kasiyahan ng consumer sa ModelDerm ay bahagyang mas mababa kaysa sa mga bayad na konsultasyon sa telemedicine.

Ang Q-switched Nd:YAG laser ay kilala sa epektibong paggamot sa nevus ng Ota at mga katulad na kondisyon. Nagsagawa kami ng isang pag-aaral upang makita kung gaano kahusay ang isang high-fluence 1064 nm Q-switched Nd:YAG laser sa mga Mongolian spot sa mga hindi pangkaraniwang lugar, nang hindi nagiging sanhi ng pagliwanag ng balat. Pinag-aralan namin ang 61 mga pasyente na may mga batik na ito, na sinusuri ang kabuuang 70 mga sugat. Ang kalahati ng mga sugat ay ginamot sa laser, habang ang iba ay hindi ginamot para sa paghahambing. Sinuri namin ang mga resulta gamit ang isang sukat at isang aparato na tinatawag na Mexameter® upang sukatin ang mga antas ng melanin. Ang mga pasyente ay sinundan para sa isang average ng 14 na buwan sa pangkat ng paggamot at 18 buwan sa grupo ng pagmamasid. Sa pagtatapos ng pag-aaral, nakakita kami ng mga makabuluhang pagkakaiba sa mga marka ng sukat at mga antas ng melanin sa pagitan ng mga ginagamot at hindi ginagamot na mga grupo, na ang pangkat na ginagamot ng laser ay nagpapakita ng mas mahusay na mga kinalabasan. Ang high-fluence Q-switched Nd:YAG laser, nang hindi nagiging sanhi ng pagpapaputi ng balat, ay napatunayang epektibo at ligtas para sa paggamot sa mga hindi pangkaraniwang Mongolian spot na ito.
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.

Pinag-aralan namin ang pagiging epektibo at kaligtasan ng paggamit ng isang partikular na paggamot sa laser para sa ABNOM , at tiningnan kung anong mga salik ang maaaring makaapekto sa kung gaano ito gumagana. Tiningnan namin ang 110 pasyente na nagkaroon ng ABNOM at nakakuha sa pagitan ng dalawa at siyam na laser treatment. Nalaman namin na ang paggamot ay gumana nang mas mahusay kapag mas matagal itong ginawa, ngunit hindi rin sa mga matatandang pasyente. Mas mahusay din itong gumana sa mga pasyente na may mas magaan na balat (uri III) at mas maliliit na apektadong lugar (mas mababa sa 10 cm2) . Ang pagkakaroon ng melasma kasama ng ABNOM ay ginawang hindi gaanong epektibo ang paggamot. Ang kulay o bilang ng mga apektadong lugar ay tila walang pagkakaiba. Humigit-kumulang 10% ng mga pasyente ang nakakuha ng mas madidilim na mga spot pagkatapos ng paggamot. Ang maagang maraming paggamot ay nagbigay ng magagandang resulta. Ang mga matatandang pasyente na may mas maitim na balat at mas maitim na mga spot ay mas malamang na makakuha ng mas madidilim na mga spot pagkatapos ng paggamot. Para sa mga pasyenteng may ABNOM at melasma, mas mabuting gumamit ng lower-energy laser para maiwasang lumala ang 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.

○ Paggamot
Ang mga pampaputi ay bihirang tumulong. Hindi tulad ng melasma, ang ABNOM ay maaaring mapabuti sa paggamot sa laser at hayaang alisin nang walang pag-ulit. Maaaring isagawa ang laser treatment ng 10 hanggang 20 beses upang gamutin ang ABNOM.
