RESUMO

INTRODUCTION: The Coronavirus disease 2019 (COVID-19) pandemic has greatly affected medical practices worldwide. Due to the transmissibility of the SARS-CoV-2 virus, the risks and benefits of conducting non-emergent and aesthetic procedures have shifted. This study primarily aimed to investigate the different factors affecting the physician's decision to conduct dermatologic surgery procedures during the COVID-19 pandemic based on their own vaccination status. Secondly, this study also aimed to determine the level of institutional trust in the respondents' respective governments and ministries of health. METHODS: This was a questionnaire-based cross-sectional study conducted from October to December 2021. The survey was electronically distributed to members of the Cyber Conference of Aesthetic Dermatology and Skin Surgery in APAC (CyAsia) and members of dermatological societies across nine countries in Asia. The survey asks the participants' tendencies to perform procedures based on patient willingness to undergo nasal swabbing prior to the procedure, the type of procedure to be performed (cancer removal vs. filler augmentation), and the type of vaccine received by the physician (inactivated, viral vector, mRNA or protein-based). RESULTS: A total of 351 participants completed the questionnaire. Data were analyzed using a conditional logistic regression model according to the participants' country of origin, specialty, age, level of trust in the national government, and level of trust in their respective health ministries. Tendencies to conduct dermatologic procedures were highest for doctors who received mRNA vaccines and lowest among doctors who received inactivated vaccines. Willingness of the patients to undergo pre-procedure nasal swabbing was also a significant factor in deciding to treat, whereas the type of procedure performed was a non-significant factor. CONCLUSIONS: This study highlights the important factors that influence the decision to conduct dermatologic procedures during the COVID-19 pandemic.

RESUMO

INTRODUCTION: This split-face, double-blind, randomized controlled study investigated the efficacy and safety of using a microneedling radiofrequency (RF) device with polynucleotides (PN) versus RF alone for the treatment of melasma. METHODS: Thirty adult participants with melasma (Fitzpatrick skin types III-V) received three treatments with an invasive, bipolar, pulsed-type microneedling RF device on both sides of the face. The treatment sessions occurred once every 2 weeks. The hemifaces of each participant were designated for treatment and control with PN and normal saline solution (NSS), applied after treatment with RF. Measurements were made of melanin index (MI), erythema index (EI), skin roughness (by the Antera 3D system), modified melasma area severity index (mMASI) for each hemiface, and patients' self-assessed improvement. These occurred at baseline and again following the final treatment (2 weeks and 1, 2, 3, and 6 months after). Mean values were obtained for MI, EI, skin roughness, and mMASI. A generalized estimating equation (GEE) was used to compare the obtained values for the outcome measures across all assessment points. RESULTS: All patients were women (mean age, 43.2 ± 7.0 years). Mixed melasma predominated (61.5%; n = 16), and the mean duration of melasma was 8.9 ± 6.5 years. Twenty-six participants were followed up to the 6-month assessment point. Significant improvements were observed from baseline in MI, skin roughness, and mMASI scores for both the PN and control sides at 6 months, with no statistically significant differences between sides. Patients' self-assessed improvement scores also showed a positive trend. Melasma recurrence was observed in three patients at 2, 3, and 4 months after the last treatment session (10% recurrence rate). CONCLUSIONS: The combination of an invasive, bipolar, pulsed-type microneedling RF with PN is not superior compared with microneedling RF alone in the treatment of melasma. Microneedling RF may be considered as safe and efficacious for the improvement of skin roughness, and as an adjunctive treatment option for melasma. CLINICAL TRIAL REGISTRATION: This study was registered on ClinicalTrials.gov and assigned NCT number TCTR20210804002.
