Ultrasound in Aesthetics: Filler and Non-Filler Applications.

Ultrasound in aesthetics presents multiple applications in several areas, including diagnosing fillers and non-fillers complications, the performance of ultrasound-guided injections in real-time, and identifying the most common types of cosmetic fillers. Furthermore, this application of ultrasound in aesthetics has become a must for managing aesthetic patients because, to date, this modality is the one that provides the higher resolution among imaging techniques, detailed anatomical information, and blood flow detection, besides showing worldwide availability. This paper aims to review the current applications of ultrasound in aesthetics based on publications from scientific literature and the authors' experience.

Rationale and Guidelines for the Use of Hyaluronidase: A Practical Guide for Complications Caused by Hyaluronic Acid.

The use of enzyme hyaluronidase to treat the complications of different brands of hyaluronic acid (HA) dermal fillers is increasing in the same proportion as the number of nonsurgical cosmetic procedures. Guidelines for diagnosing and treating complications remain controversial and are primarily based on anecdotal reports and small case series. We proposed approaching HA-related complications based on our clinical research and observations of treating more than 200 patients and providing a practical guide for the thoughtful use of hyaluronidase according to adverse events.

Recalcitrant Sterile Abscesses by Volux: A New Therapeutic Approach.

The number of patients developing sterile abscesses because of hyaluronic acid (HA) filler procedures has increased for unknown reasons. We described this adverse reaction after filling with Juvederm Volux, the latest innovative product in the Vycross range of technology. We presented five patients with recalcitrant sterile abscesses after filling with Juvederm Volux who did not respond to the traditional therapy but whose lesions were resolved with the "Munhoz-Cavallieri lavage protocol" developed and recently published by the present authors.

Short-term Accrual 2019 European League Against Rheumatism/American College of Rheumatology Domains and Systemic Lupus International Collaborating Clinics/American College of Rheumatology Damage in Lupus Patients With and Without Nephritis at Disease Onset.

Objective: To determine in a historical inception cohort the impact of lupus nephritis at disease onset in short-term accrual 2019 European League Against Rheumatism (EULAR)/American College of Rheumatology (ACR) domains. The possible association with treatment and damage was also investigated.

Methods: One hundred thirty-three consecutive adult systemic lupus erythematosus patients according to the 2019 EULAR/ACR criteria were divided according to the presence (RENAL-lupus) or absence of renal involvement (NONRENAL-lupus) at disease onset.

Participating as a research team during the COVID-19 pandemic benefits mental health of undergraduate medical students in Brazil.

During the COVID-19 pandemic, undergraduate medical students (UMS) exposed to isolation, social distancing and complete or partial face-to-face educational activities interruption may present increased stress, depression and anxiety. This study was undertaken to evaluate if, during isolation, UMS involved in online group activities as investigators of a research project (volunteer group) would present better mental health than their colleagues, not involved in that research (control group). A Web-based survey, via the Google Forms platform, including details on demographic data, life habits, previous health conditions, worries with the COVID-19 pandemic, sleep pattern modifications and depression, anxiety and mental stress, using the DASS-21 (Depression, Anxiety and Stress Scale) was implemented from 20 July to 31 August 2020.

NOT SO "HAPPY BUMP": A complication due to hyaluronic acid.

Introduction: The use of hyaluronic acid (HA) as a dermal filler is considered safe. However, as new brands come to the market, reports of adverse events are becoming more and more common.

Objective: To describe a particular type of adverse effect that, unlike the erythematous, indurated, and painful nodules described in the literature as "angry red bumps," is characterized by noninflammatory, stony-like nodules that appear in sites previously treated with HA.

Sterile abscess due to hyaluronic acid: A new diagnosis and a proposal for treatment-A series of eight cases.

Background: In recent years, fillers procedures with hyaluronic acid (HA) have grown significantly. Despite HA relative safety, the number of cases of complications after injections has grown, and in many of which, we are not aware of or have little control over.

Aims: In this article, the authors describe a new adverse reaction after filling with HA injection, the sterile abscess.

Incidence and risk factors for moderate/severe COVID-19 in rheumatic diseases patients on hydroxychloroquine: a 24-week prospective cohort.

Objectives: To evaluate the incidence of COVID-19 and its main outcomes in rheumatic disease (RD) patients on hydroxychloroquine (HCQ) compared to household cohabitants (HC).

Methods: This is a 24-week nationwide prospective multi-centre cohort with a control group without RD and not using HCQ. All participants were monitored through scheduled phone interviews performed by health professionals.
