Objective. This article presents a literature review to explore and analyze the current situation of pressure ulcers or lesions or decubitus ulcers, pathophysiological, epidemiological aspects, and risk factors. The progress in evidence of the effectiveness of preventive repositioning in the appearance of these lesions in vulnerable hospitalized patients is also evaluated. Methods. Databases were reviewed in non-systematic manner, including the Cochrane Wounds Specialized Register; Medline, Scopus, PubMed, the Cochrane Central Register of Controlled Trials; MEDLINE (Ovid); EMBASE (Ovid), Web of Science, SciELO, and Lilacs. The general search terms included [pressure ulcers or pressure lesions or decubitus ulcers] and [prevention or preventive] and [repositioning or positioning or position changes or postural change] and [patient at risk or vulnerable] and [hospitalized or ICU or intensive care]. Systematic literature reviews, randomized clinical trials, observational studies, cost-effectiveness and qualitative studies in English or Spanish were included. Results. Although globally, the incidence, prevalence, and years of disability associated to these lesions has diminished between 1990 and 2019, the high impact on health persists. Evidence found on the effectiveness of repositioning in preventing pressure ulcers and health associated costs has been evaluated with certainty between low and very low, as a result of conducting research with serious methodological limitations that report results with high inaccuracy. Conclusion.The findings reported present that these lesions persist at hospital level and continue being a global social and health problem with high impact on health budgets. Likewise, there is a need to develop greater quality research on prevention strategies, such as repositioning, which validate their effectiveness, and justify their use.

El lifting cervicofacial de plano profundo: Presentación de la técnica y resultados

Objetivo: El lifting cervicofacial es una técnica que busca devolver una apariencia juvenil y descansada al rostro del paciente. Originalmente, esta técnica se limitaba solamente a una disección en el plano cutáneo. El lifting de plano profundo o deep plane facelft, en cambio, utiliza un plano de disección anatómico por debajo del sistema musculoaponeurótico superficial (SMAS), permitiendo la lisis de los ligamentos de retención faciales y la máxima movilización de los tejidos superficiales, confiriéndole ventajas frente a otras técnicas. Se describe la técnica y se presenta nuestra experiencia. Material y Método: Serie de casos retrospectiva de pacientes sometidos a lifting de plano profundo en nuestro centro. Se describe la técnica quirúrgica, datos demográficos, antecedentes médico quirúrgicos y complicaciones post-operatorias. Resultados: Entre enero de 2021 y junio de 2023 se operaron 18 pacientes, todos de sexo femenino con un promedio de edad de 58,7 años. Solo 2 pacientes presentaron complicaciones (hematoma). Ningún paciente presentó lesión del nervio facial transitoria o permanente. Ningún paciente necesitó re-operación. Discusión y conclusión: La técnica de lifting de plano profundo o deep plane facelft es un método seguro y efectivo para tratar los signos del envejecimiento facial. Las complicaciones descritas por nuestro grupo son acordes a la literatura.

Aim: The facelift is a technique that aims to restore a more youthful and rested appearance to the aging face. Originally it was limited to a skin dissection only. The deep plane facelift, on the other hand, uses an anatomical dissection plane below the superficial muscular aponeurotic system (SMAS), allowing lysis of the facial retention ligaments and maximum mobilization of superficial tissues, with better outcomes than other techniques. The technique is described and our experience is presented. Material and Method: Retrospective case series of patients undergoing deep plane facelift. The surgical technique, demographic data, surgical medical history, and postoperative complications are described. Results: Between January 2021 and June 2023, 18 patients were operated, all female with an average age of 58,7 years old. Only 2 patients presented complications (hematoma). No patient presented facial nerve injury. No patient required re-operation. Discussion and Conclusion: The deep plane facelift is a safe and effective method to treat the signs of the aging face. The complications described are consistent with the literature.

Effect of facial filling with autologous fat particles on facial contour reshaping / 中华医学美学美容杂志

Objective:To explore the effect of facial filling with autologous fat particles on the facial contour remodeling of patients with facial rejuvenation needs and its influence on the facial skin indicators of patients.Methods:From February 2019 to February 2020, 225 female patients, aged 25-52 years, with an average age of (42.5±5.2) years, received facial rejuvenation treatment in Zhengzhou Mylai Medical Beauty Hospital. They were divided into observation group (PPDO serrated line lifting combined with autologous fat granule filling), control group 1 (PPDO serrated line lifting alone) and control group 2 (simple autologous fat granule filling alone), with 75 cases in each group. After 6 months of follow-up, facial skin indexes, contour remodeling effect and adverse reactions after treatment were compared among the three groups.Results:At the last follow-up, the facial skin elasticity and moisture scores of the observation group (63.45±10.11, 56.71±9.38) were significantly higher than those of control group 1 (51.11±9.23, 43.69±7.65) and control group 2 (52.35±9.51, 42.47±7.53). The facial spots and lipid scores (41.31±7.24, 42.18±7.46) were significantly lower than those in control group 1 (48.67±9.15, 53.49±9.45) and control group 2 (48.26±9.21, 53.55±9.53) ( F=37.39, 68.98, 17.42, 40.91, P<0.001). At the last follow-up, the lower surface width of observation group (11.35±0.63) was lower than that of control group 1 (12.21±0.85) and control group 2 (12.38±0.65). The contour ratio of the lower part of the face (0.63±0.17) was higher than that of control group 1 (0.56±0.15) and control group 2 (0.57±0.15) ( F=44.49, 4.36, P<0.05). The change level of the ratio of lower facial area (0.12±0.03) was higher than that of control group 1 (0.07±0.02) and control group 2 (0.08±0.04) ( F=54.31, P<0.001). Conclusions:For patients who need facial rejuvenation treatment, the use of autologous fat granule facial filling therapy has good clinical effects, which can significantly improve the patient's facial skin elasticity, moisture, spots, and oil. The patient's facial contour reshaping effect is better, and the aesthetic score is significantly improved, and does not increase the risk of adverse reactions.

Introduction: In the modern concept of facial rejuvenation, the main thing is to achieve a natural result without surgical marks. The endoscopic fronto-temporo-orbital lifting is currently the best method to achieve this. Objective: To determine the effectiveness of the endoscopic frontoplasty technique for the treatment of facial aging. Methods: A descriptive observational study of a series of 28 cases with a diagnosis of facial aging treated at the National Center for Minimal Access Surgery in the period from January 2014 to January 2017 was carried out. The variables of: sex, age, marital status, schooling, race, surgical time and intraoperative complications. Results: The mean age was 54.4 (40-73) years. The female sex prevailed (89.3 percent). The average level of schooling 61.5 percent, married marital status 52.0 percent. Ptosis of the eyebrows with the presence of frontal and glabellar wrinkles was the most frequent diagnosis 13; 46.4 percent. The mean surgical time was 80.9 (40-120) minutes. There were no intraoperative complications, conversions, or reinterventions. In 27 patients (96.4 percent) there was permanence of the results over time. Complications occurred in 4 patients (14.3 percent). There were 19 patients treated as outpatients (67.9 percent), with a hospital stay of one day (32.1 percent). All showed satisfaction with the results obtained. Conclusions: Endoscopic foreheadoplasty is a minimally invasive and very effective method for repositioning lowered eyebrows, as well as treating frontal and glabellar wrinkles(AU)

Endoscopic analysis of alterations in sinus floor elevation approaching the summers technique and immediate implant: a clinical trial with 10 years follow-up / Análise endoscópica das alterações na elevação do assoalho do seio maxilar com abordagem da técnica de Summer e implante imediato: um ensaio clínico com 10 anos de acompanhamento

The goal of this study was to evaluate by endoscopy, possible intercurrences during the sinus floor lifting employing the Summers technique, besides verify the implants' survival rate after 10 years. Six patients (12 sinus) were included in this study. The same surgeon performed the procedures, under local anesthesia and venous sedation in the hospital. All participants underwent sinus lift and implant placement in only one procedure, as previously planned, using endoscopic analysis (Stortz®). All cases received bovine bone graft (Bio-Oss®) before the implant placement. After 10 years, the patients were recalled for follow-up. Two intercurrences (16.66%) were detected using the endoscope, one simple rupture, and another perforation with the leaking of the graft within the sinus. Both were reverted and corrected immediately. There was one implant loss (8.33%), therefore this patient did not undergo any intercurrence in transoperative, and the membrane was elevated lesser than 5 mm. The survival rate reached was 91.66%. The osteotome technique constitutes a reliable method with a long-term of 10 years presenting a high implant survival rate, suggesting an elevation up to 5.5 mm in healthy patients. The occurrences in transoperative were only detected by the endoscopic analysis which must be stimulated to guarantee more secure visibility. Otherwise, the association the atraumatic technique and endoscope was tough, increased the costs, limiting the use routinely.

O objetivo deste estudo foi avaliar através de endoscopia as possíveis intercorrências durante levantamento de seio maxilar fechado, além de verificar a taxa de sobrevivência dos implantes após 10 anos. Seis pacientes (12 seios maxilares) foram incluídos neste estudo com idades entre 26 e 74 anos. O mesmo cirurgião realizou os procedimentos, sob anestesia local e sedação venosa em ambiente hospitalar. Todos os participantes foram submetidos à elevação do seio nasal e colocação do implante em apenas um procedimento, conforme planejado anteriormente, por acompanhamento transcirúrgico da endoscopia (Stortz®). Todos os casos receberam enxerto ósseo bovino (Bio-Oss®) antes da colocação do implante. Após 10 anos, os pacientes foram chamados para acompanhamento. Foram detectadas duas intercorrências (16,66%) com o endoscópio, uma ruptura simples e outra perfuração com extravasamento do enxerto para dentro do seio. Ambos foram revertidos e corrigidos imediatamente. Houve perda de um implante (8,33%), portanto esse paciente não apresentou intercorrência no transoperatório e a membrana estava elevada menos de 5 mm. A taxa de sobrevivência alcançada foi de 91,66%. A técnica do osteótomo constitui um método confiável em longo prazo (10 anos) apresentando uma alta taxa de sobrevivência do implante, sugerindo que uma elevação de até 5,5 mm em pacientes saudáveis é possível. Assim, verificou-se que as ocorrências no transoperatório foram detectadas apenas pela análise endoscópica que deve ser estimulada para garantir uma visibilidade mais segura. Por outro lado, a associação da técnica fechada com o endoscópio foi difícil, aumentou os custos, limitando seu uso como rotina

Clinical effect of mid-face lifting combined with autologous compound fat transplantation in facial rejuvenation / 中华医学美学美容杂志

Objective:To investigate the clinical effect and safety of mid-face lifting combined with compound fat transplantation in facial rejuvenation.Methods:From October 2016 to May 2020, 26 patients with mid-facial aging were enrolled, including 10 males and 16 females, with an average age of (47±6) years (38-65 years). The facial superficial musculoaponeurotic system was stripped, folded and suspended through the temporal hairline incision to lift the middle of the face. Liposuction was performed and compound fat was prepared, in which structural fat was injected into the area marked with loss of facial volume before operation, and extravascular matrix component gel was injected into the static wrinkle dermis. Six and 12 months after operation, the global aesthetic improvement scale of the observer and the global aesthetic improvement scale of the patient were scored, and the postoperative complications and patients＇ satisfaction were counted.Results:At the end of 6 months, improvements in mid face were reported in all patients by blinded reviewers. 12 months after operation, 53.8% (14 cases) of patients had significant improvement in facial aging, 30.8% (8 cases) had moderate improvement, and 15.4% (4 cases) had slight improvement; 25 patients (96%) were satisfied with the postoperative results. Postoperative hemorrhage occurred in one patient, scar hyperplasia occurred in one patient, and no obvious complications occurred in the other patients.Conclusions:The method of midface lifting combined with compound fat transplantation can improve the facial soft tissue and supplement the facial missing capacity, improve the static wrinkles of the face, and comprehensively solve the aging problem of midface. It has a definite clinical effect, fewer complications, and is safe and reliable. It has definite clinical effect with less complications.

3D stereophotogrammetry quantification for tissue repositioning using Botulinum toxin A: a case report / Quantificação por estereofotogrametria 3D para reposicionamento tecidual com Toxina botulínica A: relato de caso

Hereby, we objectively assessed the outcomes of a facial-lifting procedure with Botulinum toxin type A (BoNT-A) using a 3D stereophotogrammetry quantification (3D-SQ). A 46-year-old female patient received a full face BoNT-A treatment in a total dose of 180 Speywood Units (sU). Frontal, lateral and oblique photographs were taken before and 20 days after treatment, at rest and during mimic movements. Also, a facial scanning was performed before and 20 days after BoNT-A injections. The results were analyzed using a 3D-SQ software. The photographs showed a decrease in expression lines and dynamic wrinkles. In addition, a better-defined jawline and volume gain in the midface area with improvement of the profile appearance, due to the reduction of the sagging skin under the chin, was observed. The 3D-SQ showed volume gains of 1.17 ml on the right and of 1.59 ml on the left cheekbone areas, due to the cranially soft-tissue repositioning. In addition, a decrease in the volume of melomental folds areas (0.27ml on the right and 0.41 ml on the left side) was reported, compatible to the above-mentioned volume gain. Measurements considering cephalometric points showed a decrease in the total facial height (distance from Trichion to Mental points), suggesting a soft tissue dislocation in an upward direction. Finally, this case report showed quantitative results that can evidence the role of BoNT-A in facial- lifting procedures. These results reinforce the importance of using a 3D-SQ to assess the outcomes of BoNT-A and, probably, other aesthetic procedures.(AU)

No presente estudo avaliamos objetivamente os resultados de um procedimento de lifting facial com toxina botulínica tipo A (BoNT-A) usando uma quantificação de estereofotogrametria 3D (3D-SQ). Uma paciente do sexo feminino de 46 anos recebeu um tratamento facial completo com BoNT-A em uma dose total de 180 unidades Speywood (sU). Fotografias frontais, laterais e oblíquas foram tomadas antes e 20 dias após o tratamento, em repouso e durante os movimentos mímicos. Além disso, um escaneamento facial foi realizado antes e 20 dias após as injeções de BoNT-A. Os resultados foram analisados por meio de um software 3D-SQ. As fotografias mostraram uma diminuição das linhas de expressão e rugas dinâmicas. Além disso, observou-se um maxilar mais bem definido e ganho de volume na região média da face com melhora da aparência do perfil, devido à redução da flacidez da pele sob o queixo. O 3D-SQ apresentou ganho de volume de 1,17 ml à direita e 1,59 ml à esquerda, devido ao reposicionamento do tecido mole. Além disso, foi relatada diminuição do volume das áreas do sulco mentual (0,27 ml à direita e 0,41ml à esquerda), compatível com o ganho de volume acima citado. As medidas considerando os pontos cefalométricos mostraram uma diminuição da altura facial total (distância dos pontos Triquion ao Mentual), sugerindo um deslocamento superior dos tecidos moles. Em conclusão, este relato de caso mostrou resultados quantitativos que podem evidenciar o papel da BoNT-A em procedimentos de lifting facial. Esses resultados reforçam a importância da 3D-SQ para avaliar objetivamente os resultados de harmonização orofacial com BoNT-A e outros materiais. (AU)

Introducción: los pacientes críticos, bajo sedación y apoyo ventilatorio invasivo presentan dolor, la barrera más grande para su detección es la incapacidad de comunicarse; sin embargo, el hecho de que el paciente no pueda referir su dolor, no significa que no lo padezca. Objetivo: describir las respuestas conductuales al dolor durante el cambio postural en pacientes sedados oro intubados. Material y métodos: estudio cuantitativo, descriptivo, observacional, longitudinal. Muestra n= 50 pacientes, se utilizó la escala BPS (Behavioral Pain Scale) como instrumento de valoración del dolor, se midió en tres momentos: 1 minuto antes, durante y 10 minutos después del cambio postural. Resultados: el cambio postural del paciente con sedación y ventilación mecánica provocó dolor en 56% de los pacientes; antes de realizar el cambio postural se identificó una media del dolor de 4.6, durante el cambio postural aumento a 6.5 y posterior al cambio disminuyo a una media de 4, siendo un factor protector. Conclusiones: la movilización del paciente sedado oro intubado requiere de la participación del equipo multidisciplinar, para el manejo de la ventilación mecánica, el cuidado de sondas y catéteres, cuidados de la piel, prevención de caídas y aplicación correcta de la técnica de movilización, la cual demanda experiencia clínica del personal que participa en la valoración y manejo de las respuestas conductuales al dolor.

Introduction: critical patients, under sedation and invasive ventilatory support present pain, the greatest barrier to its detection is the inability to communicate, however, the fact that the patient cannot report their pain does not mean that they do not suffer from it. Objective: to describe the behavioral responses to pain during postural change in sedated or intubated patients. Material and Methods: quantitative, descriptive, observational, longitudinal study. Sample n = 50 patients, the BPS scale (Behavioral Pain Scale) was used as an instrument for assessing pain, it was measured at three moments: 1 minute before, during and 10 minutes after the postural change. Results: the postural change of the patient with sedation and mechanical ventilation caused unacceptable pain in 56% of the patients; Before making the postural change, a mean pain of 4.6 was identified, during the postural change it increased to 6.5 and after the change it decreased to a mean of 4, being a protective factor. Conclusions: the mobilization of the sedated or intubated patient requires the participation of the multidisciplinary team, for the management of mechanical ventilation, care of tubes and catheters, skin care, prevention of falls and correct application of the mobilization technique, which It demands clinical experience from the personnel involved in the assessment and management of behavioral responses to pain.

A densidade como uma "não tão nova" métrica da quantificação de cargas no treinamento de força / Work to rest ratio as a "not so new"metric to quantify strength training loads

O objetivo dessa carta resposta foi tecer algumas considerações sobre o ponto de vista do manuscrito "A densidade como uma nova métrica da quantificação de cargas no treinamento de força", publicado nessa tradicional revista brasileira. Erroneamente, os autores apontaram que o termo work to rest ratio utilizado no estudo Blood Pressure Response During Resistance Training of Different Work-to-Rest Ratio e publicado no Journal of Strength Conditioning Research estaria equivocado. Os autores também sugerem que a densidade seja calculada apenas pela fórmula: total de peso levantado/total de pausa. Isso limitaria o cálculo da densidade em métodos isométricos de treinamento de força, que podem ter a densidade calculada pela fórmula: tempo de tensão muscular/total de pausa. Essa breve comunicação amplia o contexto conceitual e de aplicação prática dessa métrica que é pouco conhecida no treinamento de força. (AU)

The aim of this reply letter was to present some considerations about the point of view of the manuscript "Density as new metric to quantify strength training loads", published in this traditional Brazilian journal. The authors erroneously pointed out that term "work to rest ratio" used in the study "Blood Pressure Response During Resistance Training of Different Work-to-Rest Ratio" and published in Journal of Strength Conditioning Research, would be wrong. The authors also suggest that density must be calculated only by the formula: total weight lifted / total rest interval. This would limit density calculation in isometric strength training methods, which can have density calculated by the formula: muscle tension time / total rest interval. This brief communication broadens the conceptual context and practical application of this metric that is little known in strength training. (AU)

Effect of bipolar radio frequency in combination with small incision on lower facial lifting and shaping / 中华医学美学美容杂志

Objective:To discuss the effect of bipolar radio frequency (RF) in combination with small incision on lower facial (cheek, chin and neck) shaping and rejuvenation.Methods:From August 2019 to June 2020, 26 patients (aged 35-60 years, with mean 45 years) required for facial rejuvenation and received the fine liposuction in the lower cheek, mandibular margin and submental neck area in Beijing Huangsi Plastic Surgery Hospital. With the help of bipolar RF device - EMBRACE RF (diamond carving), the facetite face and hand radiofrequency were adopted for the subcutaneous tissue to tighten the skin. A concealed small incision was made from the front of the ear to the posterior ear. The superficial layer of the superficial muscular aponeuritic system (SMAS) was stripped, folded, tightened and suspended. The excessive skin was removed while reducing multilayer tension. The incision was cosmetically sutured.Results:All 26 patients had their wounds primary healing, with no complications such as skin necrosis and sensory disorder. All the 24 patients were followed up for 6-12 months. Their scars were concealed and tiny, the skin was tight, the lifting effect was obvious, and the pouch of mouth corners disappeared or alleviated. The contour of the mandibular margin was defined and the mental cervical angle was clear. The shape of the neck was slender and the fat chin was significantly improved. The effect of facial rejuvenation was distinct. Two patients felt it worked but did not achieve the expected results. They were satisfactory after giving the second surgery 6 months later. The satisfactory rate of the first surgery was 92.3% in 24 patients.Conclusions:Bipolar RF in combination with small incision lifting surgery is effective in lower facial (cheek, chin and neck) shaping and rejuvenation. The trauma is little and the wound is recovered fast. The scar is concealed and tiny. It is worthy of clinical application.
