RESUMO
BACKGROUND: Unwanted lateral fat most prominently affects the female population and may cause self-esteem issues. OBJECTIVE: To investigate the effectiveness and safety of synchronized high-intensity focused electromagnetic (HIFEM) + radiofrequency (RF) for the treatment of lateral thigh adipose tissue. MATERIALS AND METHODS: Ninety-three subjects (21-70 year old) received 4, 30-minute HIFEM + RF treatments of the lateral thighs. Magnetic resonance imaging (MRI) of the treated area was obtained at baseline, 1, 3, and 6 months post-treatment to document the changes in fat layer thickness. Furthermore, digital photographs, circumference measurements of the lateral thighs, subjects' satisfaction questionnaires, and therapy safety and comfort were documented. RESULTS: Magnetic resonance imaging revealed a significant reduction of fat tissue in the saddlebag region peaking at 3 months (-18 ± 5.5 mm; N = 51). The thigh circumference measured at 3 predefined levels decreased on average by 2.3 cm, with the greatest change at the level of 10 cm below the infragluteal fold (-3.5 cm, 3-month follow-up). Results were maintained at 6 months. No adverse events were recorded. The therapy was found comfortable with a high satisfaction rate. CONCLUSION: High-intensity focused electromagnetic + RF treatment to the lateral thigh area demonstrated effectiveness in long-term fat thickness reduction by MRI imaging. Secondary endpoint showed simultaneous effectiveness and safety.

BACKGROUND: With age, facial muscles lose the ability to complete contractions properly, resulting in limitation of facial expressions and fat shifting, and leading to skin creases and wrinkling. OBJECTIVES: The aim of this study was to determine the effects of the novel high intensity facial electromagnetic stimulation (HIFES) technology combined with synchronized radiofrequency on delicate facial muscles, using an animal porcine model. METHODS: Eight (n = 8, 60-80 kg) sows were divided into the active group (n = 6) and the control group (n = 2). The active group underwent four 20-minute treatments with radiofrequency (RF) and HIFES energies. The control group was not treated. Histology samples of muscle tissue were collected by a punch biopsy (6 mm in diameter) from the treatment area of each animal at baseline, 1-month, and 2-month follow-up. The evaluation included staining of the obtained tissue slices with hematoxylin and eosin and Masson's trichrome to determine the changes in muscle mass density, number of myonuclei, and muscle fibers. RESULTS: The active group showed muscle mass density increase (by 19.2%, P < .001), together with elevated numbers of myonuclei (by 21.2%, P < .05) and individual muscle fibers, which increased from 56.8 ± 7.1 to 68.0 ± 8.6 (P < .001). In the control group, no significant changes were seen in any of the studied parameters throughout the study (P > .05). Finally, no adverse events or side effects were observed in the treated animals. CONCLUSIONS: The results document favorable changes after the HIFES + RF procedure at the level of the muscle tissue, which may be of great importance in terms of maintenance of facial appearance in human patients.

BACKGROUND: Several studies investigating high-intensity focused electromagnetic (HIFEM) treatments have recently been published. However, due to the novelty of the procedure, long-term data are still missing. OBJECTIVES: The aim of this study was to evaluate changes in abdominal tissues on average 1 year after a series of HIFEM treatments, to determine the long-term durability of patients' original body responses. METHODS: Magnetic resonance imaging (MRI) or computed tomography (CT) scanning were performed on 21 patients a mean of 332.6â [88.5] days after their original HIFEM treatment series. The scans were evaluated by a blinded radiologist for abdominal muscle thickness, subcutaneous fat changes, and abdominal separation. The results were compared with the MRI/CT-assisted measurements taken at baseline and 6-week follow-up. Correlations between collected data sets were calculated and tested. The incidence of any adverse events related to earlier treatments was monitored. RESULTS: When comparing the 1-year follow-up measurements with the baseline, the MRI/CT-assisted calculations revealed mean reductions of 14.63% (2.97â [2.11] mm) in fat, 19.05% (1.89â [0.88] mm) in muscle thickening, and 10.46% (1.96â [1.71] mm) in diastasis recti. All changes were significant (Pâ <â 0.05) and not related to weight fluctuations (Pâ >â 0.05). The baseline width of diastasis positively correlated with the degree of improvement at follow-up. No adverse events were reported. CONCLUSION: The HIFEM-induced muscle hypertrophy, fat reduction, and reduction in abdominal separation were maintained 1-year posttreatment. This suggests long-term durability of the original bodily response, which needs to be verified by continuing follow-up of this group and by further studies.

OBJECTIVES: This study introduces an initial evaluation of a novel High-Intensity Focused Electromagnetic (HIFEM) technology. The primary goal is to quantify any effects the treatments may have on abdominal tissues, as well as to establish hypotheses for future research of this technology. METHODS: Twenty-two patients received four abdominal treatments using the EMSCULPT device (BTL Industries Inc., Boston, MA). Anthropometric evaluations were recorded and digital photographs were taken at baseline, at 2 months, and at 6 months post-treatments. The MRI without contrast determined by vertertebras T12 and S1 (FIESTA and FSPRG sequences) was used to measure dimensions in coronal cross-sectional images of abdominal muscle and fatty tissues, in order to assess any anatomical changes induced by the application. RESULTS: Analysis of the same MRI slices verified by tissue artefacts showed a statistically significant (all P < 0.0001) average 18.6% reduction of adipose tissue thickness, 15.4% increase in rectus abdominis muscle thickness, and 10.4% reduction in rectus abdominus separation (diastasis recti) as measured from the medial border of the muscle 2 months post-treatment. More significant improvements were observed in patients with BMI 18.5-24.9 (classified as "normal"). MRI data from 6-month follow-up suggest the changes can be preserved in longer term. Tape measurements showed on average 3.8 cm subumbilical circumference reduction. The weight of the subjects did not change significantly (average -0.5 lb; P > 0.05). No adverse events were reported. CONCLUSIONS: MRI, considered as a highly precise diagnostic method, revealed simultaneous muscle growth, fat reduction and reduced abdominal separation at 2 months and at 6 months post treatments, unrelated with dieting. Further research should investigate the exact physiological processes which stand behind the tissue changes observed in this study. Lasers Surg. Med. 51:40-46, 2019. © 2018 The Authors.

BACKGROUND: Bacterial biofilms have been implicated with breast implant complications including capsular contracture and anaplastic large-cell lymphoma. The actual mechanisms for either are still under active investigation and are not clear. Due to their increased surface area, implants with textured surfaces may harbor greater biofilm loads than those with smooth surfaces. METHODS: Biofilm formation on the outer surface material was compared using implants with various surface areas and roughness, including Natrelle® (Smooth), SmoothSilk®/SilkSurface® (Silk), VelvetSurface ® (Velvet), Siltex®, and Biocell®. The roughness and surface area of each material were assessed using non-contact profilometry. Bacterial attachment (2 h) and biofilm formation (24 h) were evaluated for Staphylococcus epidermidis, Pseudomonas aeruginosa, and Ralstonia pickettii over nine independent experiments using a CDC biofilm reactor and viable plate counts (VPCs) as well as confocal scanning laser microscopy. VPCs of the textured implants were compared relative to the Smooth implant. RESULTS: Surface areas increased with roughness and were similar among the three least rough implants (Smooth, Silk, and Velvet) and among the roughest implants (Siltex and Biocell). Overall, VPC indicated there was significantly more bacterial attachment and biofilm formation on the Siltex and Biocell implants than the Silk or Velvet implants, although there were differences between species and time points. CSLM confirmed the formation of thicker biofilms on the implants with rougher surface textures. CONCLUSION: This in vitro study confirmed that implant surfaces with rougher texture, resulting in more surface area, harbored greater biofilm loads than those with smoother surfaces.

BACKGROUND: Although general guidelines are available for established silicone gel breast implants, the unique characteristics of the latest Motiva implants warrant specific guidelines. OBJECTIVES: This study aimed to generate consensus recommendations and summarize expert-based advice to better understand current surgical practices and to establish guidelines for surgeons transitioning from other implant devices to the Motiva implants. METHODS: A survey was compiled by 12 plastic surgeon experts in aesthetic and reconstructive breast surgery and 1 biotechnology scientist, and distributed to 36 plastic surgeons to establish a consensus on the use of these devices. Surgical techniques, complication rates, and implant selection were among the topics discussed. RESULTS: The experts agreed on 3 core principles regarding the use of Motiva Round and Ergonomix implants. Firstly, the dissected pocket needs to be close fitting and steps must be taken to prevent expansion of the pocket. Secondly, implant selection must be individualized. Finally, surgical planning and technique must be carefully considered. When questioned about problems they had ecountered, 84.6% of the experts agreed that they experienced fewer overall complications and 76.9% confirmed reduced capsular contracture rates with these devices. Overall, 84.6% of the experts favored selecting Motiva Ergonomix implants over Round implants to achieve a more natural look. In addition, 92.3% of the experts agreed that Motiva implants, due to their innovative technology, reduce the risk of anaplastic large-cell lymphoma. CONCLUSIONS: This international consensus of leading practitioners will assist plastic surgeons with patient selection, preoperative planning, and surgical technique. These recommendations are designed to optimize surgical outcomes, resulting in lower overall complication rates, more natural-looking breasts, and highly satisfied patients.

INTRODUCTION: A new temperature-controlled device has been used as a percutaneous radio frequency probe to treat lax submental and other facial areas. It has significant advantages over other esthetic devices as it provides the dual benefit of fat lipolysis and skin tightening. Our goal here is to present consensus recommendations for treating the aging neck. METHODS: A panel of 11 expert physicians convened in Dallas, Texas, on October 15, 2016 to arrive at a consensus on the best current practice for submental skin tightening and contour improvement. Prior to the meeting, a comprehensive review of the literature was performed and a survey was sent to esthetic dermatologists and plastic surgeons who were queried about various aspects of neck rejuvenation. RESULTS: The literature search revealed 10 different technologies for neck rejuvenation evaluated in double-blind (n = 2) and single-blind (n = 1) clinical trials and other clinical evaluations (n = 21). The survey was sent via an email to 1248 individuals and was completed by 92 respondents. Review of the data and discussion by meeting attendees generated eight consensus recommendations. DISCUSSION: Subdermal monopolar radio frequency represents an effective means for disrupting fat volume and skin tightening of the face, neck, and jawline. For suitable patients, this treatment can be used to achieve significant esthetic improvements.

BACKGROUND: The application of radiofrequency (RF) and HIFES on the body provides improvement in skeletal muscle tissue, reduction in fatty tissue, reorganization of connective tissue, and skin texture improvement. However, overall facial appearance relies on both skin and underlying structures, specifically muscles and connective tissue which have to be treated as one unit to achieve proper care while preserving fatty layers that define youth facial appearance. AIMS: The aim of this study is to find whether the effect of novel RF + HIFES is safe and can induce the lifting of soft tissue and overall improvement in facial appearance. METHODS: In this study, 21 subjects were enrolled. The therapy was administered in four 20-min treatments on the forehead and cheeks. Photographs were evaluated by a Global Aesthetic Improvement Score (GAIS) and linear measurements of facial tissue lifting at 1- and 3-month follow-ups. Volumetric changes in the cheek area were investigated as well. The patients' satisfaction, safety, and comfort were documented throughout the study. RESULTS: The data indicated improvement in overall facial appearance, and 23% of average lifting was found in brows (p = 3.14 × 10-12 ) and cheeks (p = 6.00 × 10-15 ). The assessment of digital photographs showed an improvement in 100% of patients at 3-month follow-up. The treatments were safe, accompanied by high therapy comfort and subject satisfaction of 98%. CONCLUSIONS: The treatment by simultaneous RF and HIFES technology produces significant changes to the overall facial appearance, characterized by the lifting of facial tissues.

BACKGROUND: Visceral adipose tissue (VAT), present in the abdominal cavity, oftentimes contributes to an unpleasant aesthetic appearance and can be correlated with serious health issues. High-intensity focused electromagnetic field (HIFEM) technology with synchronized radiofrequency (RF) was recently used for abdominal body shaping through subcutaneous fat reduction and muscle growth. AIM: This study aimed to assess the effect of HIFEM + RF technology on VAT tissue. METHODS: Data of 16 men and 24 women (22-62 years, 21.2-34.3 kg/cm2 ) from the original study were retrospectively reviewed. All subjects received three 30-min HIFEM + RF abdominal treatments once weekly for three consecutive weeks. The VAT area was measured in the axial plane of MRI scans at two levels: L4-L5 vertebrae and 5 cm above this level. The VAT was identified, segmented, and calculated, yielding total area in square centimeters per scan at both specified levels. RESULTS: By thoughtful review of the subject's post-treatment MRI scans, no other changes in the abdominal cavity were found except for VAT. The evaluation showed a VAT reduction of 17.8% (p < 0.001) on average at 3-month follow-up, maintaining the results up to 6 months (-17.3%). Averaging the values obtained from both measured levels, the VAT, occupied an area of 100.2 ± 73.3 cm2 at the baseline. At the 3-month follow-up, the subjects achieved an average reduction of 17.9 cm2 , preserving the results at 6 months (-17.6 ± 17.3 cm). CONCLUSION: This retrospective analysis of MRI images objectively documented the effect of HIFEM + RF abdominal therapy on VAT. The data indicates considerable VAT reduction without serious adverse events following the HIFEM + RF procedure.

Plastic surgery offices are subject to a wide variety of cybersecurity threats, including ransomware attacks that encrypt the plastic surgeon's information and make it unusable, as well as data theft and disclosure attacks that threaten to disclose confidential patient information. Cloud-based office systems increase the attack surface and do not mitigate the effects of breaches that can result in theft of credentials. Although employee education is often recommended to avoid the threats, a single error by a single employee has often led to security breaches, and it is not reasonable to expect that no employee will ever make an error. A recognition of the two most common vectors of these breaches, compromised email attachments and surfing to compromised websites, allows the use of technical networking tools to both prevent email attachments from being received and to prevent employee use of unsanctioned and potentially compromised websites. Further, once compromised code is allowed to run within the office network, that code must necessarily make outbound connections to exploit the breach. Preventing that outbound traffic can mitigate the effects of a breach. However, most small office network consultants design firewalls to only limit incoming network traffic and fail to implement technical measures to stop the unauthorized outbound traffic that is necessary for most network attacks. Detailed techniques are provided which can be used to direct IT consultants to properly limit outbound network traffic as well as incoming email attachments, with more information at https://officenetworksecurity.com.
RESUMO
SUMMARY: Although robotic surgery has been routinely established in other surgical disciplines, robotic technologies have been less readily adopted in plastic surgery. Despite a strong demand for innovation and cutting-edge technology in plastic surgery, most reconstructive procedures, including microsurgery, have continued to necessitate an open approach. Recent advances in robotics and artificial intelligence, however, are gaining momentum and have shown significant promise to improve patient care in plastic surgery. These next-generation surgical robots have the potential to enable surgeons to perform complex procedures with greater precision, flexibility, and control than previously possible with conventional techniques. Successful integration of robotic technologies into clinical practice in plastic surgery requires achieving key milestones, including implementing appropriate surgical education and garnering patient trust.

BACKGROUND: High levels of visceral adipose tissue (VAT) are associated with abdominal obesity and increased risk of metabolic deterioration. Recent studies showed that intensive physical exercise results in the reduction of subcutaneous and visceral fat. AIMS: This study investigates the effect of supramaximal muscle contractions induced by a HIFEM procedure for abdominal VAT changes. METHODS: Computed tomography (CT) scans of 22 subjects (47.3 ± 8.4 years, BMI of 23.5 ± 3.5 kg/m2 ) who received 8 HIFEM treatments of the abdomen (2-3 days apart) were retrospectively evaluated for the changes in VAT. The CT scans were obtained at baseline and 1 month after the last treatment. The transverse slices at umbilical, infraumbilical, and supraumbilical levels were used to determine the cross-sectional area (CSA) of VAT through a semi-automated segmentation method. RESULTS: Analysis of the CSA revealed a significant (P = .004) and uniform reduction of the abdominal VAT area by 14.3% (-16.7 cm2 ) from 110.6 ± 69.0 cm2 to 93.9 ± 54.6 cm2 . In general, a higher relative improvement was seen infraumbilically (17.1%), followed by supraumbilical (15.5%) and umbilical (10.7%) levels. The reduction of VAT was strongly correlated to the reduction of subcutaneous fat (r(17) = 0.66; P = .002). A decrease in VAT volume contributed to the overall aesthetic enhancement visible on digital photographs. CONCLUSIONS: The outcomes indicate that HIFEM technology has a positive effect on VAT. However, further studies are necessary to validate these outcomes and to clarify the exact mechanism of a VAT reduction. Based on our results, the HIFEM procedure may be a beneficial treatment option for patients with high VAT deposits.
