Women in Dermatology: Considerations over Their Recognition and Prominence.

According to the Federal Council of Medicine's demographic data from 2020, the medical specialty with the highest number of women is dermatology; with 77.9% within the total of 9,078 specialists. The male/female ratio is 0.28, that is, for each man, there are more than 3 women Dermatologists. Analyze the participation of women in Brazilian dermatology and their representation in leadership positions through data review. A literature review of the National Library of Medicine PubMed database was performed in May 2022 and data review of the SBD database. According to the Brazilian Society of Dermatology (SBD), about 80% of its associated Doctors are women. Despite this correlation, since its foundation in 1912, the SBD has already had 62 directorates, of which 53 were known to be presided over by men and 4 of them are unknown. Among the directorates that are known, only five (8.62%) were chaired by women.

Applied anatomy of the layers and soft tissues of the forehead during minimally-invasive aesthetic procedures.

BACKGROUND: An increasing demand of minimally-invasive aesthetic procedures of the forehead concomitantly leads to higher numbers of adverse events. Adequate application of anatomical knowledge is required to increase safety and efficacy of different minimally-invasive aesthetic procedures in this anatomical region. OBJECTIVE: To describe the layered anatomy of the forehead soft tissues with respect to their thicknesses and how they relate to different minimally-invasive aesthetic treatments. METHODS: A total of n = 85 healthy study participants (69 females and 16 males) with a mean age of 40.84 ± 10.9 years and a mean body mass index of 22.65 ± 2.6 kg/m2 were investigated with ultrasound-based imaging to measure the thickness of different forehead soft tissues. RESULTS: The mean overall soft tissue thickness of the forehead was measured to be 4.18 ± 0.7 mm for the entire study population. Increasing BMI values correlated statistically significantly with increasing thickness of all measured forehead soft tissues with exception of the frontalis muscle. On a statistically significant level, males showed thicker forehead soft tissues than females, with exception of the retrofrontalis fat and the frontalis muscle. CONCLUSION: On basis of the findings obtained in this study, basic treatment principles can be derived and improved for the injection of neuromodulators, hyaluronic acid as well as the application of polydiaxonane (PDO) threads and micro-focused ultrasound. Precise knowledge and thorough understanding of the layers and soft tissues of the forehead is required to guarantee safe and effective procedures in this aesthetically important facial region.

Improvement of Facial Skin Laxity by a Combined Technique With Hyaluronic Acid and Calcium Hydroxylapatite Fillers: A Clinical and Ultrasonography Analysis.

BACKGROUND: Facial aging involves skeletal changes, loss of volume in the fat compartment, and skin component changes. The current objective of cosmetic facial filling is to reestablish the overall aspect that was lost during the aging process. Hyaluronic acid (HA) and calcium hydroxyapatite (CaHA) fillers are indicated for facial rejuvenation, and these agents promote dissimilar effects regarding volume restoration and dermal biostimulation. OBJECTIVE: This study aimed to assess clinical and ultrasonographic improvements in facial skin laxity using a technique that combines the injection of HA and CaHA. METHODS: A 120-day follow-up, quasi-experimental study was conducted based on the enrollment of fifteen women (36–47 years old) with mild face flaccidity scores who underwent subcutaneous injection of up to 3 mL of HA (zygomatic-malar region, pyriform aperture, temporal region, and jaw) followed by 3 mL of 1:1 diluted CaHA using a fan technique (temporal, zygomatic-malar, and jaw regions). OBJECTIVE: Adverse effects were registered, and the monthly assessed outcomes included clinical improvement, satisfaction, and high-frequency ultrasonography (dermal thickness) parameters. RESULTS: At 120 days of follow-up, clinical assessment by blinded physicians yielded six (40%) very improved patients and nine (60%) exceptionally improved patients. All the participants were highly satisfied with the results and reported exceptional improvement. Dermal thickness increased 11.1% (8.8–13.4%), and augmented dermal homogeneity was evidenced by ultrasonography. Local adverse effects were mild and transient. CONCLUSION: In conclusion, the combined technique with HA and CaHA fillers was well-tolerated and yielded high satisfaction and safe improve in facial skin laxity and dermal thickness in women with mild midface aging.

A vacinação contra SARS-CoV-2 afeta o efeito imediato da toxina botulínica? Primeiras impressões / Does SARS-CoV-2 vaccination affect the immediate effect of botulinum toxin? First impressions

Introdução: A infecção por SARS-CoV-2 se espalhou rapidamente pelo mundo desde sua identificação no final de 2019. Globalmente, até abril de 2021, houve mais de 150 milhões de casos confirmados de Covid-19, incluindo mais de 3 milhões de mortes. Portanto, uma corrida foi prontamente iniciada para produzir uma vacina eficaz contra o novo vírus. A injeção de toxina botulínica continua sendo o principal procedimento cosmético não cirúrgico em todo o mundo, com alto índice de eficácia e satisfação do paciente. Objetivos: Este estudo tem como objetivo analisar a associação entre a vacina SARS-CoV-2 e a resposta imediata à toxina botulínica. Materiais e Métodos: Estudo observacional, retrospectivo e multicêntrico. Os dados foram coletados entre abril e junho de 2021, e revisão de prontuários de 71 pacientes de 27 a 76 anos que foram tratados com injeção de toxina botulínica. Resultados e Conclusão: Não houve mudanças significativas no desfecho imediato dos pacientes vacinados para Covid-19 e toxina botulínica, mas é de suma importância ressaltar que são necessários acompanhamento e mais estudos para definir se a vacina Covid-19 é capaz de alterar a duração do efeito e a eficiência da toxina botulínica.

Background: The SARS-CoV-2 infection has spread worldwide rapidly since its identification at the end of 2019. Globally, until April 2021, there have been more than 150 million confirmed cases of Covid-19, including over 3 million deaths. Therefore, a race was promptly started to produce an effective vaccine against the new virus. Botulinum toxin injection remains the leading non-surgical cosmetic procedure worldwide, with a high rate of efficacy and patient satisfaction. Aims: This study aims to analyze the association between the SARS-CoV-2 vaccine and the immediate botulinum toxin response. Materials and Methods: This was an observational, retrospective, and multicenter study. Data were collected between April and June 2021, and a medical record review of 71 patients from 27 to 76 years old treated with botulinum toxin injection. Results and Conclusion: There were no meaningful changes in the immediate outcome of patients vaccinated for Covid-19 and botulinum toxin. However, it is vital to underline that follow-up and further studies are needed to define whether the Covid-19 vaccine can alter the duration of effect and efficiency of the botulinum toxin.
