Analysis of modified ilib therapy in patients submitted to plastic surgery.

The sample comprised 44 volunteers who had undergone some surgical procedure and were equally divided into four groups. G1 started the therapy 24 h after the surgical procedure with the device off. G2 followed the same time pattern, 24 h, but with the device turned on. G3 and G4 started therapy three days after the surgical procedure; in G3, the device was turned off, and in G4, the device remained on during therapy; each session lasted 30 min, using 660 nm (red), energy 180 J. For all groups, the therapy started with daily use for seven days and followed the interval use of three times a week until completed 21 days. The revaluation was performed after 7 and 21 days. The results found show changes in HR at rest, systolic and diastolic BP, and in peripheral oxygen saturation, which showed a significant difference in the groups that used on-therapy (p < 0.05). In the MCGILL Scale evaluation, the mean total score showed a more accentuated drop in the groups that used ILIB, (p < 0.05). ILIB may have prevented a more significant evolution of firosis levels; however, no changes were observed in the evaluation of sleep and anxiety. The application of the ILIB in patients undergoing plastic surgery was supported in terms of hemodynamics and pain; in addition, starting the ILIB application 24 h after the procedure proved to be more advantageous.

Effectiveness of Light-Emitting Diode Epilation on Different Skin Types: A Pilot Study.

Objective: This study analyzed the histological and immunohistochemical changes in hair follicles submitted to epilation with light-emitting diode (LED). Background: The use of specific wavelengths of LED leads to the absorption of photons by chromophore tissues, enabling different photophysical and photochemical events, bringing therapeutic benefits such as removing body hair. Methods: The sample included five participants, with phototypes II-V, divided into two groups. The volunteers received a session of epilation with the Holonyak® device on the pubic region and right groin, whereas the contralateral side was kept as a control. An energy of 10 J and a cooling temperature of -5°C were used, after which the pain provoked by the equipment was questioned using the analogue pain scale. After 45 days, the punching procedure was performed in the region where skin samples were taken for histological and immunohistochemical analysis. Results: For all phototypes, in the treated area, the follicles and sebaceous glands were in a stage of involution, showing perifollicular inflammatory infiltrate with changes suggestive of apoptosis. The apoptosis process was confirmed by the increase in markers cytokeratin-18 and cleaved caspase 3, in addition to the reduced expression of Blc-2, and the lower cell proliferation (Ki67), reinforcing the action of LED based on the definite involution and resorption of the follicle, through macrophages (CD68) triggered by the inflammatory process. Conclusions: The preliminary results of this study found relevant histological changes and immunohistochemical markers in the epilation process, which may indicate the efficacy of LED in permanent hair removal.

Use of Stationary Ultrasound Device In Subcutaneous Abdominal Fat Tissue: Analysis of Clinical Effects.

Background: High-intensity stationary therapeutic ultrasound (HITU) technology is gaining popularity as an attractive modality for treating different conditions, but little is known about its application in aesthetics. Objective: To analyze the effects of stationary unfocused ultrasound (HITU technology) in treating localized fat in women's abdominal region. Methods: The sample consisted of 43 women with localized abdominal adiposity, assessed pre and post-treatment by assessment protocols, adversity analysis questionnaires, ultrasound exams, and serum level exams. The volunteers were randomly divided into three subgroups: G-1, who used the device off, G-2 received therapy with the device once a week for two months (Parameters: Pulsed - 100Hz - 50% - 4.0 W/cm2 - 20 minutes) and the G-3 who used the device on twice a week for a month (Parameters: Pulsed - 100Hz - 50% - 3.2W/cm2 - 30 minutes). All groups received eight sessions in total. Results: There was a significant reduction for G-3 in the plicometry of the lower right region (p=0.01) in the comparison between the final and initial moments. In the comparison among the three research groups, there was a significant reduction in plicometry in the lower right (p=0.03) and left (p=0.02) regions in G3. Via ultrasound, a reduction in the fat layers average was observed in all groups. In G-3, there were significant differences in the left infraumbilical region (p=0.02) and right (p=0.04). In the group comparison, the right infraumbilical region showed significant differences (p=0.04) for the G-3. No differences were found for weight, BMI, body fat percentage and supra, infra and umbilical perimetry (p>0.05). The adverse reactions reported were: Mild hyperaemia (75%) and sensation of shock (21%), there were also reports of improvement in fluid retention in 93.7 percent of the volunteers, and most were satisfied with the result. Conclusion: Both treatment protocols for the reduction of localized adiposity were effective compared to the placebo group, with a significant reduction in the use of ultrasound and plicometry in the concentration of fat in the lower abdominal region.

Effects of Ultracavitation and Radiofrequency on Abdominal Adiposity.

Background: The mechanism of fat reduction from radiofrequency occurs via the thermal stimulation of adipocyte metabolism, causing a lipase-mediated triglyceride enzyme degradation, apoptosis, and adipocyte rupture. Ultracavitation promotes fat reduction using adipose cell destruction through mechanical stimulus. The literature on the combination of these two physical agents, named ultrafrequency, is still scarce and requires consistent analysis of the effects of this therapy combination. Objective: The objective of this study was to investigate the effects of radiofrequency associated with ultracavitation in the treatment of abdominal subcutaneous tissue of women. Methods: This was a prospective, randomized clinical trial in which 45 participants were divided into three distinct groups: the control group (no treatment); ultracavitation group; and ultracavitation and radiofrequency (UCV+RF) group, each with 15 volunteers. The following variables were evaluated: weight, perimetry, plicometry, ultrasonography, treatment reactions, and patient satisfaction. Results: The participants in the UCV+RF group presented a more significant decrease in adipose tissue, which was verified through all the evaluation methods. Conclusion: Based on our results, the simultaneous application of ultracavitation and radiofrequency generated a reduction in localized adiposity superior to the isolated use of ultracavitation.

Analysis of the Effects of Cryofrequency on Localized Fat.

BACKGROUND: Cryofrequency combines cryotherapy with radiofrequency, reaching the tissue in different layers, providing various biological effects, and reducing localized adiposity. OBJECTIVE: We sought to evaluate the efficacy of cryofrequency in reducing localized adiposity. METHODS: The study population consisted of 63 women with infra-abdominal adiposity, evaluated before and after treatment using evaluation protocols, questionnaires, and ultrasound imaging. The volunteers were randomly distributed into three subgroups; of these, Group 1 (G01) received the cryofrequency treatment (temperature of -10°C, 85% power); Group 2 (G02) underwent cryofrequency associated with ultracavitation (frequency of 60 Hz, 70% power, shooting at 25%, duty cycle of 60% on and 40% off); and the control group (CG) received cryotherapy alone (temperature of -10°C). All groups were submitted to four treatment sessions, one session per week. RESULTS: The reduction in the fat layer analyzed by ultrasonography showed that the right side of G01 presented a significant difference in comparison with CG (p=0.01); a significant difference was also observed in the comparison between the G01 and G02 groups (p=0.001). Considering the left side, significant differences were observed in G01 when compared with CG (p=0.01) and between G01 and G02 (p=0.001). The variables of plicometry and perimetry presented a significant difference relative to in CG; however, no differences were observed with regard to weight or body mass index (p>0.05). The majority of participants reported positive feelings about the treatment. CONCLUSIONS: The cryofrequency protocol alone led to a significant reduction in the fat layer but its association with ultracavitation led to superior results.

Effects of the extracorporeal shock wave therapy on the skin: an experimental study.

Extracorporeal shock wave therapy (ESWT) has been extensively studied for its multiple biological properties, and although it is widely applied in esthetical procedures, little is known about its effects on the epidermis and dermis. In this study, a histological and immunohistochemical study of the effects of ESWT was performed on rat skin. Forty-five female rats were treated with one or two sessions of ESWT and sacrificed on days 1, 7, 14, and 21 after treatment. The samples were histologically processed and then morphometric analyses were performed to assess the epidermis, dermis, and subcutaneous fat tissue thickness. Immunohistochemical reactions were also performed against the antibodies: basic fibroblastic growth factor (FGF2), its receptor (FGFR1), and α-smooth muscle actin. Slides were scanned and digitally assessed, to determine the microvessel density (MVD) and digital scoring of the immunohistochemical staining. The results showed that ESWT produced a significantly higher collagen content, MVD, and epidermis and dermis thickness than the control, non-treated group. Both in epidermis and dermis, FGF2 was overexpressed in the ESWT-treated groups, whereas FGFR1 was increased only in the group treated with two ESWT sessions at 21-days post-treatment. The ESWT-treated groups have also shown diminished thickness of subcutaneous fat tissue. In conclusion, ESWT induces neocollagenesis and neoangiogenesis, and upregulates the FGF2 expression, particularly in the groups treated with two sessions. Furthermore, it was demonstrated that overexpression of FGF2 on skins treated with ESWT seems to be a key role on its mechanism of action.

Effects of contrast cryolipolysis on flank region adiposity: Case study.

BACKGROUND: The Contrast Cryolipolysis is a non-invasive technique that aims to reduce localized adiposity with its heating-cooling-heating method, resulting in a 45% fat loss in the treated area, with no damage to the skin. OBJECTIVE: To investigate the effects of contrast cryolipolysis compared to conventional cryolipolysis on localized adiposity. MATERIALS AND METHODS: This is a case study was carried out with two volunteers. The cirtometry, ultrasonography, and the anthropometric characteristics' analyses of volunteers were performed before and after the intervention. The right flank region underwent conventional cryolipolysis, and the left flank underwent contrast cryolipolysis. RESULTS: The procedures performed in both volunteers had positive results. However, the use of Contrast Cryolipolysis promoted greater loss of adipose tissue, reducing perimetry and cirtometry measurements, as well as the adipose tissue thickness, acknowledged via ultrasonography. CONCLUSION: The contrast cryolipolysis promotes greater localized adiposity reduction than the conventional cryolipolysis.

Effects of Cryolipolysis on Abdominal Adiposity.

Cryolipolysis is a noninvasive technique of localized fat reduction. Controlled cold exposure is performed in the selective destruction of fat cells. The aim of this study was to investigate the effects of cryolipolysis on adipocytes elimination through histological and sonographic analyses. This study reports the case of a 46-year-old female patient, with complaint of localized abdominal fat and in the preoperative period of abdominoplasty. The patient was submitted to a single 60-minute application of cryolipolysis, temperature of -5°C, on the hypogastrium area, 5 cm below the umbilicus. To study the effects of this treatment, ultrasound images taken before the session and 7, 15, 30, and 45 days after the therapy were analysed. After the abdominoplasty, parts of the treated and the untreated withdrawn abdominal tissues were evaluated macro- and microscopically. In ultrasound images, as well as in macroscopic and histological analyses, significant adipocytes destruction was detected, with consequent fat layer reduction and integrity of areas that were adjacent to the treated tissue. The presence of fibrosis observed during therapy and acknowledged through performed analyses encourages further studies to clarify such finding.
