    Evaluation of the evidence level for the use of radiofrequency in aesthetic treatments: A systematic review and meta-analysis
    (2021) PAGGIARO, Andre Oliveira; PINHEIRO, Rafael; SOARES, Kaolanna; CARVALHO, Viviane Fernandes; GEMPERLI, Rolf
    Background Radiofrequency (RF) is a non-invasive or minimally invasive procedure with a low risk of complications. It has been employed for several aesthetic purposes. Aim This study aimed to conduct a systematic literature review on the use of RF for aesthetic applications and assess the level of accumulated evidence for each condition. Methods Using the MEDLINE/PubMed and EMBASE databases, we searched for articles published from 2009 to 2019 describing the use of RF treatment for aesthetic purposes. Results Our search approach identified 25 randomized clinical trials investigating the efficacy of RF in the following clinical situations: body contour improvement, facial rejuvenation, acne scar treatment, alopecia, and rosacea. There were problems with the quality of the studies, especially regarding selection, performance, and detection bias. Conclusion Our study revealed that RF treatment is potentially promising in all of the evaluated clinical situations; however, we were not able to identify a level of evidence that justifies its use over other therapeutic options currently available on the market.

    Effect of different human tissue processing techniques on SARS-CoV-2 inactivation-review
    (2021) PAGGIARO, Andre Oliveira; CARVALHO, Viviane Fernandes; GEMPERLI, Rolf
    The safety of the tissue transplant recipient is a top priority for tissue banks, and the emergence of the new coronavirus SARS-CoV-2 has raised significant concerns about the risks of releasing tissue for clinical use. In the present study, we conducted a literature review about the potential infectivity of SARS-CoV-2 in different biological tissues and the influence of various tissue processing and sterilization procedures on viral inactivation. The search revealed that SARS-CoV-2 binds to the human angiotensin-converting enzyme receptor to penetrate human cells. These receptors are present in skin cells, musculoskeletal tissue, amniotic membranes, cardiovascular tissue and ocular tissues, including the cornea. In general, we found that coronaviruses are stable at low temperatures, and inactivated upon exposure to extreme heat and pH. Notably, gamma irradiation, which has already been employed to inactivate SARS and MERS, could be useful for sterilizing skin, amnion and musculoskeletal tissues against SARS-CoV-2. We conclude that due to the limited information about the effects of physical and chemical tissue processing methods on viral neutralization, rigorous donor screening is still essential for tissue transplant recipient safety.
