Comparison of the effects of 2 frequencies of application of photobiomodulation on facial rejuvenation: Controlled, randomized, and double-blind clinical trial.

INTRODUCTION: Skin aging is an irreversible, slow and progressive process, mainly influenced by age, but also by external factors such as ultraviolet radiation, smoking, and alcohol, among others. It is increasingly common to look for procedures that slow down skin aging by limiting or hiding its effects on appearance. Studies have shown the benefits of photobiomodulation (PBM) for the skin, especially with the use of red light-emitting diodes. However, there is a high level of variability in the treatment parameters and frequency of application. METHODS AND ANALYSIS: The objective of this study is to compare the effects of PBM with a light-emitting diode mask (660 nm, 6.4 mW/ cm², 8,02 J/ cm², 5.02 mW, 21 minutes) on facial rejuvenation using 2 frequency applications for 4 weeks: one group will receive PBM application on the face, twice a week and another group will receive PBM application 3 times a week. A group with simulated PBM applied twice a week for 4 weeks will be used as a control. The treatment will be performed on female participants aged between 45 and 60 years. After 4 weeks, evaluations of photographic images by specialists (Wrinkle Assessment Scale) as well as the quantitative analysis of the wrinkle size by the Image J software, the depth and width of wrinkles (assessment of face impressions by optical coherence tomography) and the level of Satisfaction with Facial Appearance Overall will be compared with data collected before the start of the study. All data will be analyzed statistically according to their distribution, seeking a level of statistical significance of 0.05. ETHICS AND DISSEMINATION: This protocol was approved by the Research Ethics Committee of the Nove de Julho University (acceptance number: 4.365.565). This trial has been registered in ClinicalTrials.gov (ID: NCT04911140). This study is recruiting.

Effect of the combination of photobiomodulation therapy and the intralesional administration of corticoid in the preoperative and postoperative periods of keloid surgery: A randomized, controlled, double-blind trial protocol study.

Keloid scars are characterized by the excessive proliferation of fibroblasts and an imbalance between the production and degradation of collagen, leading to its buildup in the dermis. There is no "gold standard" treatment for this condition, and the recurrence is frequent after surgical procedures removal. In vitro studies have demonstrated that photobiomodulation (PBM) using the blue wavelength reduces the proliferation speed and the number of fibroblasts as well as the expression of TGF-ß. There are no protocols studied and established for the treatment of keloids with blue LED. Therefore, the purpose of this study is to determine the effects of the combination of PBM with blue light and the intralesional administration of the corticoid triamcinolone hexacetonide on the quality of the remaining scar by Vancouver Scar Scale in the postoperative period of keloid surgery. A randomized, controlled, double-blind, clinical trial will be conducted involving two groups: 1) Sham (n = 29): intralesional administration of corticoid (IAC) and sham PBM in the preoperative and postoperative periods of keloid removal surgery; and 2) active PBM combined with IAC (n = 29) in the preoperative and postoperative periods of keloid removal surgery. Transcutaneous PBM will be performed on the keloid region in the preoperative period and on the remaining scar in the postoperative period using blue LED (470 nm, 400 mW, 4J per point on 10 linear points). The patients will answer two questionnaires: one for the assessment of quality of life (Qualifibro-UNIFESP) and one for the assessment of satisfaction with the scar (PSAQ). The team of five plastic surgeons will answer the Vancouver Scar Scale (VSS). All questionnaires will be administered one, three, six, and twelve months postoperatively. The keloids will be molded in silicone prior to the onset of treatment and prior to excision to assess pre-treatment and post-treatment size. The same will be performed for the remaining scar at one, three, six, and twelve months postoperatively. The removed keloid will be submitted to histopathological analysis for the determination of the quantity of fibroblasts, the organization and distribution of collagen (picrosirius staining), and the genic expression of TGF-ß (qPCR). All data will be submitted to statistical analysis. Trial registration: This study is registered in ClinicalTrials.gov (ID: NCT04824612).

Effect of hyperbaric oxygenation on random rat skin flaps vascularization.

PURPOSE: To evaluate the effect of hyperbaric oxygenation (HBO) on angiogenesis in random rat skin flaps, by immunoexpression of vascular endothelial growth factor A (VEGF-A). METHODS: Forty adult rats were divided into four groups: GE) epilated; GE/HBO) epilated subjected to HBO; GER) epilated submitted to dorsal skin flap; GER/HBO) epilated subjected to dorsal skin flap + HBO. HBO was performed with rats inside a chamber under atmosphere close to 100% oxygen and pressure of 2.4 absolute atmospheres, 2h per day during seven consecutive days. GE and GER groups were placed in the hyperbaric chamber without HBO. Then, under anesthesia, skin flaps were removed and separated into three portions relative to pedicle fixation. The samples were fixed in formalin and processed for paraffin embedding. Histological sections were submitted to immunohistochemistry for VEGF-A detection. The number of immunostained-blood vessels were counted under light microscopy. RESULTS: GE and GE/HBO groups showed normal and similar skin morphology in the three flap portions. A fibrin-leukocyte crust, along with denatured collagen and intense leukocyte infiltrate, was mainly observed in the dermis of the medial and distal flap portions of GER group. Meanwhile, the GER/HBO group presented more regions with intact collagen and small areas of leukocyte infiltrate in the three flap regions. VEGF-A-immunostained blood vessels were largely seen in all regions of GE and GE/HBO groups, whereas no significant differences were found between these groups. A decrease in vascularization was noticed in GER and GER/HBO groups, which was more evident in the most distal portion of the flaps. However, the number of VEGF-A-immunostained blood vessels in GER/HBO group was significantly higher when compared to GER group. CONCLUSIONS: Hyperbaric oxygenation was associated with increased angiogenesis and improved viability of rat skin flaps.

Apresentação aguda da doença de Mondor em pós-operatório de mamoplastia de aumento com implantes de silicone / Acute presentation of Mondor's disease after breast augmentation with silicone implants

Há 50 anos, no Jefferson Davis Hospital, em Houston (EUA), realizou-se a primeira cirurgia de mamoplastia de aumento com implantes de silicone. Atualmente, o avanço da tecnologia médica disponibilizou no mercado implantes de diversas formas e texturas, assim como permitiu o desenvolvimento de inúmeras técnicas para a realização desta cirurgia. Este procedimento cirúrgico pode apresentar algumas complicações locais imediatas e tardias no pós-operatório. Por se tratar de um implante constituído de material biocompatível ao organismo, mesmo com 50 anos de evolução, deve-se sempre estudar e, se possível, relatar as possíveis complicações que possam ocorrer. O objetivo deste artigo é revisar as complicações mais frequentes que ocorrem no pós-operatório das mamoplastias de aumento com implante de silicone, bem como relatar o caso de uma complicação atípica, doença de Mondor, no pós-operatório desta cirurgia.

The first breast augmentation surgery with silicone implants was performed at the Jefferson Davis Hospital in Houston (USA) about 50 years ago. Recent advances in medical technology have made implants of various shapes and textures commercially available and led to the development of numerous techniques for performing this surgery. However, this surgical procedure may have some immediate and long-term local complications . Since the implant is made of biocompatible material , it is important to investigate and report complications that occur despite the 50 years of research. The purpose of this study was to review the most frequent complications occurring after breast augmentation surgery with silicone implants and to report a case of an unusual complication, Mondor's disease.

An experimental model to retraining in microvascular suture.

PURPOSE: To demonstrate an experimental model of up to four hours a week of independent study that allows relearning in microvascular sutures. METHODS: Wistar rats between 200 and 500 grams surplus research experiments were used. Femoral vessels are covered on one or both sides through a groin incision obliquely along the inguinal ligament. Femoral artery and vein are isolated and measured being clamped and cut. The individual performs in microvascular anastomosis complexity arterial and venous terminoterminal sequence. terminolateral and venous and arterial grafts in vessels. Permeability is evaluated by testing vascular patency after creation of microvascular anastomosis. RESULTS: In the first specimen, only arterial and venous vascular anastomosis are performed terminoterminal. The average diameter of the femoral veins varies from 0.8 to 2 mm between rodents (artery, between 0.6 and 1.4 mm, between 0.8 and 2 mm vein). The superficiality of the vessels allows faster dissection, may also be held in other inguinal region. CONCLUSION: The model of individual retraining allows learning microvascular suture in individuals of permanent staff.

A gastrocnemius heterotopical transplant model with end-to-side neurorraphy.

PURPOSE: To present an animal model to assess the effects of end-to-side innervation in the heterotopically transplanted model with reduced chances of neural contamination. METHODS: The medial portion of the gastrocnemius muscle in wistar male rats was isolated and its pedicle dissected and performed a flap in the abdominal portion. To prevent neural contamination in the abdominal region, the muscle was wrapped with a Goretex(r) sheet. The specimens were divided into 2 groups (G). In G1 was performed an end-to-end suture between tibial nerve of the gastrocnemius and femoral motor nerve and between the saphenous sensory nerve and the motor nerve. In G2 was performed a end-to-side suture between the tibial nerve and the motor femoral and between the tibial nerve and saphenous motor nerve. The specimens were evaluated 60 days later to check the structure of the neurorraphy. Sections were obtained proximal and distal to the coaptation site. RESULTS: The medial gastrocnemius muscle had the advantage of maintaining visible mass after 60 days. No disruption of the coaptation site was found. No major injury to the donor nerve was seen in group 2. CONCLUSION: The proposed model is simple, reproduciple and prevent the neural contamination in the flap in end-to-side suture.

Existe efeito protetor da oxigenação hiperbárica em retalhos cutâneos randômicos?: um estudo imuno-histoquímico de apoptose celular e fator de crescimento vascular endotelial / Does hyperbaric oxygenation have a protective effect on random skin flaps? An immunohistochemical study of cellular apoptosis and vascular endothelial growth factor

INTRODUÇÃO: A oxigenação hiperbárica (OHB) tem por objetivo aumentar em pelo menos 10 vezes a pressão tecidual de oxigênio, diminuindo os efeitos deletérios da isquemia. O objetivo deste estudo é investigar o papel da oxigenação hiperbárica na expressão imuno-histoquímica da caspase 3 e do fator de crescimento endotelial vascular (VEGF) em retalhos randômicos em ratos. MÉTODO: Trinta e dois ratos Wistar machos foram divididos aleatoriamente em quatro grupos: grupo sham (GS), grupo N-acetilcisteína (GNAC), grupo OHB (GOHB) e grupo OHB + N-acetilcisteína (GHN). Um retalho de pele retangular (2 cm x 8 cm) foi dissecado a partir da camada muscular dorsal, preservando um pedículo cranial. Uma lâmina de polietileno foi colocada sobre a camada muscular e fixou-se o retalho no local original. No 8º dia, foram coletadas biópsias (2 cm x 1 cm) de espessura total das áreas proximal, média e cranial e de um local fora do retalho, que serviu como área de controle. RESULTADOS: A expressão de VEGF nas camadas da pele e nos vasos não apresentou diferenças significativas entre os grupos. As células apoptóticas estavam significativamente aumentadas na área central do retalho em todos os grupos. O maior aumento ocorreu nos grupos GS e GNAC. A OHB diminuiu significativamente o número de células caspase 3 positivas nas camadas da pele e nos vasos das três áreas. CONCLUSÕES: A OHB foi associada a expressão reduzida de apoptose. A expressão de VEGF em camadas da pele e vasos não demonstrou diferença significativa. Os resultados sugerem que a difusão do oxigênio através do espaço intersticial foi o fator determinante para os resultados mais favoráveis da OHB na diminuição da expressão de apoptose.

BACKGROUND: Hyperbaric oxygenation (HBO) therapy aims to increase oxygen tissue pressure by at least 10 times and decrease the adverse effects of ischemia. The aim of this study was to investigate the effect of HBO on the immunohistochemical expressions of caspase 3 and vascular endothelial growth factor (VEGF) in random flaps in rats. METHODS: Thirty-two male Wistar rats were randomly divided into 4 groups: the sham group (GS), the N-acetylcysteine group (GNAC), the HBO group, and the HBO + N-acetylcysteine group. A rectangular skin flap (2 × 8 cm) was dissected from the dorsal muscle layer, and a cranial pedicle was preserved. A polyethylene film was placed on the muscle layer, and the flap was fixed in the original site. On the eighth day, biopsy samples (2 × 1 cm) of the entire thickness of the proximal, medial, and cranial areas as well as of the site outside the flap, which was used as a control, were collected. RESULTS: VEGF expression in the skin layers and vessels was not significantly different between the groups. The number of apoptotic cells was significantly increased in the area of the flap in all groups. The highest increase was noted in the GS and GNAC groups. HBO significantly reduced the number of caspase 3-positive cells in the skin layers and vessels of the 3 areas. CONCLUSIONS: HBO was associated with decreased apoptosis. VEGF expression in the skin layers and vessels did not differ significantly. The results suggest that oxygen diffusion through the interstitial space was the determining factor for the positive effect of HBO on the decrease in apoptosis.

Treatment of bilateral mammary ptosis and pectus excavatum through the same incision in one surgical stage.

CONTEXT: Congenital deformities of the anterior thoracic wall are characterized by unusual development of the costal cartilages. All these medical conditions are frequently associated with a variety of breast deformities. Several surgical techniques have been described for correcting them, going from sternochondroplasty to, nowadays, minimally invasive techniques and silicone prosthesis implantation. CASE REPORT: The present article reports the case of a young female patient who presented bilateral mammary ptosis and moderate pectus excavatum that caused a protrusion between the eighth and the tenth ribs and consequent esthetic disharmony. The proposed surgical treatment included not only subglandular breast implants of polyurethane, but also resection of part of the rib cartilage and a bone segment from the eighth, ninth and tenth ribs by means of a single submammary incision in order to make the scar minimally visible. Correction through a single incision benefited the patient and provided an excellent esthetic result. CONCLUSIONS: The techniques used to repair bilateral mammary ptosis and pectus excavatum by plastic and thoracic surgery teams, respectively, have been shown to be efficient for correcting both deformities. An excellent esthetic and functional result was obtained, with consequent reestablishment of the patient's self-esteem.

Efeito da oxigenação hiperbárica e da N-acetilcisteína na viabilidade de retalhos cutâneos em ratos / Effects of hyperbaric oxygenation and N-acetylcysteine on the survival of random-pattern skin flaps in rats

INTRODUÇÃO: Os avanços das técnicas em cirurgia plástica permitiram a reconstrução de extensos defeitos causados por ferimentos, entre as quais destaca-se a utilização dos retalhos randômicos. No entanto, o fator limitante para a utilização desses retalhos é a imprevisibilidade de sua vascularização distal, o que poderá ocasionar danos irreversíveis à microcirculação, resultando em necrose parcial ou completa do retalho, tornando a ferida mais suscetível a infecção. Portanto, melhorar a viabilidade do retalho randômico, principalmente em sua extremidade distal, tem sido uma meta importante para o sucesso dessa técnica. O objetivo deste estudo foi investigar o papel da oxigenação hiperbárica (OHB), da N-acetilcisteína (NAC) e da associação de ambas (OHB + NAC) na área de necrose em retalhos randômicos modificados de McFarlane em pele de ratos Wistar. MÉTODO: No total, 32 ratos Wistar machos foram divididos aleatoriamente em grupo Sham (GS, n = 8), grupo N-acetilcisteína (GNAC, n = 8), grupo oxigênio hiperbárico (GOHB, n = 8) e grupo oxigênio hiperbárico + N-acetilcisteína (GHN, n = 8). Sob anestesia geral, foi executado um retalho randômico modificado de McFarlane na região dorsal dos ratos. RESULTADOS: A necrose média foi de 18,3 por cento, 24,3 por cento, 12,6 por cento e 14,9 por cento, respectivamente, nos grupos GS, GNAC, GOHB e GHN. Os grupos GOHB e GHN apresentaram diferença significativa quando comparados ao grupo GNAC. CONCLUSÕES: A OHB está associada a redução da área de necrose do retalho cutâneo. A NAC foi associada a maus resultados quando usada isoladamente. A associação dos dois procedimentos, OHB e NAC, não potencializou os resultados favoráveis observados com o uso da OHB isoladamente. As descobertas sugerem que a difusão de oxigênio através do espaço intersticial foi o fator determinante de resultados mais favoráveis da OHB.

BACKGROUND: Advances in plastic surgery techniques have enabled reconstruction of extensive wound damage, especially through the use of random flaps. However, the limiting factor for the use of these flaps is the unpredictable blood supply, which may produce irreversible damage to the microcirculation and result in partial or complete flap necrosis, making the wound more susceptible to infection. Therefore, improvement of random flaps, especially in the distal extremity, has been an essential goal for the success of this technique. The objective of this study was to investigate the effects of hyperbaric oxygenation (HBO), N-acetylcysteine (NAC), and the combination of both (HBO + NAC) on the degree of necrosis in modified McFarlane random skin flaps on Wistar rats. METHODS: A total of 32 male Wistar rats were randomly divided into a sham treatment group (SG, n = 8), N-acetylcysteine group (NACG, n = 8), hyperbaric oxygenation group (HBOG, n = 8), and hyperbaric oxygenation plus N-acetylcysteine group (HNG, n = 8). Modified McFarlane random flaps were created in the dorsal region of the rats. RESULTS: The average area of the flaps exhibiting necrosis was 18.3 percent, 24.3 percent, 12.6 percent, and 14.9 percent, in the SG, NACG, HBOG, and HNG, respectively. The necrotic areas in the HBOG and HNG were significantly smaller than that in the NACG. CONCLUSIONS: HBO treatment was associated with a reduction in the area of necrosis in the skin flaps. NAC treatment alone gave poor results. The use of HBO and NAC in combination did not improve the outcome compared with the use of HBO alone. The findings suggest that oxygen diffusion through the interstitial space was the factor responsible for the favorable results of HBO.

The global satisfaction index with respect to the aesthetic and functional results showed that 85.48 percent of the patients were satisfied; 88.3 percent of patients were pleased with the aesthetic results, and 83.3 percent reported satisfactory functional results and could breathe easily. Regarding the impression of the patients' family and friends, 93.3 percent reported that they were completely pleased; 93.3 percent reported that the postoperative nasal form rarely or never limited social or professional activities; 75 percent of the patients were completely confident that nasal appearance was the best possible, while 76.7 percent reported that their nasal appearance could not be changed by another surgery and 83.4 percent did not believe that nasal function could be changed with another surgery. CONCLUSIONS: Rhinoplasty performed at the Plastic Surgery Department of Santa Casa de Misericórdia de Porto Alegre resulted in a high level of patient satisfaction.

Coloboma palpebral: relato de caso de tratamento cirúrgico / Congenital upper eyelid colobomas: case report of surgical treatment

Coloboma palpebral congênito é um raro defeito embriológico que ocasiona falhas no desenvolvimento palpebral. Pode afetar tanto a pálpebra superior quanto a inferior, uni ou bilateralmente. Sua importância clínica reside no fato de que, em sua localização mais comum, a pálpebra superior, tais defeitos provocam exposição da córnea, o que pode levar a ulcerações e, posteriormente, a cegueira. Existem várias técnicas cirúrgicas reparadoras dos colobomas de pálpebra superior, a escolha da técnica dependerá da extensão do defeito. O diagnóstico imediato e sua posterior reparação poderá evitar futuras complicações. O presente trabalho tem como objetivo a descrição de uma técnica cirúrgica simples e eficaz e uma revisão sobre coloboma palpebral.

Congenital eyelid coloboma is a rare embryonic defect that causes failure in eyelid development. It can affect both the upper and the lower eyelid, uni– or bilaterally. Its clinical significance lies in the fact that, in their usual location – the upper lid –, such defects cause exposure of the cornea, which can lead to ulceration and eventually blindness. There are several surgical techniques to repair upper eyelid colobomas, the choice of technique will depend on the extent of the defect. The immediate diagnosis and subsequent repair may prevent further complications. This paper aims at describing a simple and effective surgical technique and a review of eyelid coloboma.

Immunohistochemical expression of apoptosis and VEGF expression on random skin flaps in rats treated with hyperbaric oxygen and N-acetylcysteine.

OBJECTIVE: We sought to investigate the role of hyperbaric oxygen (HBO2), N-acetylcysteine (NAC), and HBO2 plus NAC (HN) on the immunohistochemical expression of caspase-3 and the vascular endothelial growing factor (VEGF) on random skin flaps of rats (modified McFarlane design). METHODS: Thirty-two male Wistar rats were randomly divided into four groups: GS (sham--n = 8); GNAC (N-acetylcysteine--n = 8); GHBO2 (hyperbaric oxygen--n = 8); and GHN (HBO2 plus NAC--n = 8). A rectangular skin flap (2 x 8 cm2) was dissected from the muscular dorsal layer, preserving a cranial pedicle. Polyethylene film was placed over the muscular layer, and an interrupted 3.0 nylon suture fixed the flap into the original place. On the eighth day, full-thickness biopsies (2 x 1 cm2) were collected from the proximal, middle and cranial areas of the skin flap, and in a site away from the flap labeled the control area. RESULTS: The expression of VEGF in the skin layers (epidermis, dermis, subcutaneous muscles) and vessels showed no significant difference among the groups. Apoptotic cells were significantly increased in the middle area of the flap in all groups. The major increase occurred in GS and GNAC. HBO2 significantly decreased cleaved caspase-3-positive cell numbers in the skin layers and vessels of the three areas. CONCLUSIONS: HBO2 showed a protective effect in the ischemic skin flap that was associated with reduced expression of apoptosis. GNAC and GHN were not associated with lower expression of apoptosis, and poor results were observed in GNAC. The combination of NAC and HBO2 did not show better results than using them separately. The expression of VEGF in skin layers and vessels did not show a significant difference in our modified McFarlane flap model. The results suggest that the diffusion of oxygen through the interstitial space was the determining factor for the more favorable results of HBO2 in the decrease of apoptosis expression.

Reconstrução de lábio inferior pós-mordedura equina: descrição de técnica e revisão anatômica / Lower lip reconstruction after equine bite: technique description and anatomy review

Introdução: A cirurgia reconstrutiva do lábio, seja superior ou inferior, possibilita sua reconstrução por meio de uma variedade de técnicas cirúrgicas. Nessas reconstruções, é importante avaliar as características do tecido (cor da pele, textura), o qual sempre que possível deve ser utilizado próximo ao local da lesão, para fornecer o melhor resultado estético e funcional possível. Relato do Caso: O presente trabalho tem como objetivo descrever a técnica de Bernard-Burow para reconstrução de lábio inferior, e revisar a anatomia do terço inferior da face, por meio do relato de caso de um paciente que foi mordido por um cavalo e teve avulsão de lábio inferior e porção mentoneana e submentoneana da face.
