ABSTRACT Objective: To report outcomes from the largest multicenter series of penile cancer patients undergoing video endoscopic inguinal lymphadenectomy (VEIL). Materials and Methods: Retrospective multicenter analysis. Authors of 21 centers from the Penile Cancer Collaborative Coalition-Latin America (PeC-LA) were included. All centers performed the procedure following the same previously described standardized technique. Inclusion criteria included penile cancer patients with no palpable lymph nodes and intermediate/high-risk disease and those with non-fixed palpable lymph nodes less than 4 cm in diameter. Categorical variables are shown as percentages and frequencies whereas continuous variables as mean and range. Results: From 2006 to 2020, 210 VEIL procedures were performed in 105 patients. Mean age was 58 (45-68) years old. Mean operative time was 90 minutes (60-120). Mean lymph node yield was 10 nodes (6-16). Complication rate was 15.7%, including severe complications in 1.9% of procedures. Lymphatic and skin complications were noted in 8.6 and 4.8% of patients, respectively. Histopathological analysis revealed lymph node involvement in 26.7% of patients with non-palpable nodes. Inguinal recurrence was observed in 2.8% of patients. 10y- overall survival was 74.2% and 10-y cancer specific survival was 84.8%. CSS for pN0, pN1, pN2 and pN3 were 100%, 82.4%, 72.7% and 9.1%, respectively. Conclusion: VEIL seems to offer appropriate long term oncological control with minimal morbidity. In the absence of non-invasive stratification measures such as dynamic sentinel node biopsy, VEIL emerged as the alternative for the management of non-bulky lymph nodes in penile cancer.

Abstract This study investigates how Regulatory Ordinance No. 120 of March 17, 2020, reflects the constitutional principles and international treaties recognized by Brazil. This Ordinance is a non-statutory regulation to fight COVID-19 seeking to prohibit the entry of people from Venezuela during this pandemic. This deductive investigation assumes that this measure is not supported by the national and international migration laws incorporated by Brazil. The legal justifications the act used as arguments were found to be inconsistent with the formal requirements for the act itself as per the Brazilian legal framework. Verification of its legal and technical justifications showed a lack of legal, scientific, and empirical support, turning the Ordinance into a target of criticism by Civil Society organizations. In light of national and international law, the analysed instrument can be considered in breach of international technical guidelines for administering vulnerable migrant influxes as is the case of Venezuelans in Brazil.

Resumo Este estudo tem como objetivo investigar como a Portaria nº 120, de 17 de março de 2020 reflete os princípios constitucionais e tratados internacionais reconhecidos pelo Brasil. A presente portaria é apresentada como medida infralegal de combate ao COVID-19 buscando proibir o ingresso de pessoas oriundas da Venezuela. A investigação dedutiva parte do pressuposto de que a portaria não se sustentaria frente às legislações migratórias nacionais e internacionais incorporadas pelo Brasil. Constatou-se que as justificativas legais apresentadas pelo ato infralegal apresentara inconsistências com as exigências formais para o referido ato. Verificou-se que as justificativas jurídicas e técnicas apresentadas pela portaria carecem de lastro legal, científico e empírico, tornando a medida alvo de críticas pela sociedade civil. Considerou-se que, frente ao direito nacional e internacional, o fechamento realizado pelo instrumento infralegal analisado vai de encontro às orientações técnicas para administração de fluxos de migrantes vulneráveis, que incluem Venezuelanos no Brasil.

Abstract Background Cardiovascular complications of COVID-19 are important aspects of the disease’s pathogenesis and prognosis. Evidence on the prognostic role of troponin and myocardial injury in Latin American hospitalized COVID-19 patients is still scarce. Objectives To evaluate myocardial injury as independent predictor of in-hospital mortality and invasive mechanical ventilation support in hospitalized patients, from the Brazilian COVID-19 Registry. Methods This cohort study is a substudy of the Brazilian COVID-19 Registry, conducted in 31 Brazilian hospitals of 17 cities, March-September 2020. Primary outcomes included in-hospital mortality and invasive mechanical ventilation support. Models for the primary outcomes were estimated by Poisson regression with robust variance, with statistical significance of p<0.05. Results Of 2,925 patients (median age of 60 years [48-71], 57.1% men), 27.3% presented myocardial injury. The proportion of patients with comorbidities was higher among patients with cardiac injury (median 2 [1-2] vs. 1 [0-2]). Patients with myocardial injury had higher median levels of brain natriuretic peptide, lactate dehydrogenase, creatine phosphokinase, N-terminal pro-brain natriuretic peptide, and C-reactive protein than patients without myocardial injury. As independent predictors, C-reactive protein and platelet counts were related to the risk of death, and neutrophils and platelet counts were related to the risk of invasive mechanical ventilation support. Patients with high troponin levels presented a higher risk of death (RR 2.03, 95% CI 1.60-2.58) and invasive mechanical ventilation support (RR 1.87, 95% CI 1.57-2.23), when compared to those with normal troponin levels. Conclusion Cardiac injury was an independent predictor of in-hospital mortality and the need for invasive mechanical ventilation support in hospitalized COVID-19 patients.

Resumo Fundamento As complicações cardiovasculares da COVID-19 são aspectos importantes da patogênese e do prognóstico da doença. Evidências do papel prognóstico da troponina e da lesão miocárdica em pacientes hospitalizados com COVID-19 na América Latina são ainda escassos. Objetivos Avaliar a lesão miocárdica como preditor independente de mortalidade hospitalar e suporte ventilatório mecânico em pacientes hospitalizados, do registro brasileiro de COVID-19. Métodos Este estudo coorte é um subestudo do registro brasileiro de COVID-19, conduzido em 31 hospitais brasileiros de 17 cidades, de março a setembro de 2020. Os desfechos primários incluíram mortalidade hospitalar e suporte ventilatório mecânico invasivo. Os modelos para os desfechos primários foram estimados por regressão de Poisson com variância robusta, com significância estatística de p<0,05. Resultados Dos 2925 pacientes [idade mediana de 60 anos (48-71), 57,1%], 27,3% apresentaram lesão miocárdica. A proporção de pacientes com comorbidades foi maior nos pacientes com lesão miocárdica [mediana 2 (1-2) vs. 1 (0-20)]. Os pacientes com lesão miocárdica apresentaram maiores valores medianos de peptídeo natriurético cerebral, lactato desidrogenase, creatina fosfoquinase, N-terminal do pró-peptídeo natriurético tipo B e proteína C reativa em comparação a pacientes sem lesão miocárdica. Como fatores independentes, proteína C reativa e contagem de plaquetas foram relacionados com o risco de morte, e neutrófilos e contagem de plaquetas foram relacionados ao risco de suporte ventilatório mecânico invasivo. Os pacientes com níveis elevados de troponina apresentaram um maior risco de morte (RR 2,03, IC95% 1,60-2,58) e suporte ventilatório mecânico (RR 1,87;IC95% 1,57-2,23), em comparação àqueles com níveis de troponina normais. Conclusão Lesão cardíaca foi um preditor independente de mortalidade hospitalar e necessidade de suporte ventilatório mecânico em pacientes hospitalizados com COVID-19.

ABSTRACT Objective: This study aimed to determine the differences in body fat distribution and central obesity indicators using dual-energy X-ray absorptiometry (DXA), adiposity indices, and anthropometric indices between women with and without polycystic ovary syndrome (PCOS). Materials and methods: Clinical and laboratory examination history, including transvaginal ultrasound, fasting blood samples, anthropometric measurements, and DXA scans were conducted in 179 women with PCOS (PCOS group) and 100 without PCOS (non-PCOS group). The volunteers were grouped by body mass index (BMI): normal (18-24.9 kg/m2), overweight (25-29.9 kg/m2), or obese (>30 kg/m2). The visceral adiposity index (VAI) and lipid accumulation product (LAP) were calculated, regions of interest (ROIs) were determined, and the fat mass index (FMI) was calculated using DXA. Results: VAI, LAP, ROIs, FMI, and adiposity indices by DXA were higher in women with PCOS and normal BMI. In both PCOS and non-PCOS groups, the ROIs progressively increased from normal BMI to overweight and obese, and from overweight to obese. Obese women with PCOS showed high trunk fat mass. However, obesity was not able to modify these trunk/periphery fat ratios in PCOS from overweight to higher BMI. These variables were associated with the incidence of PCOS. Conclusion: In women with PCOS and normal BMI, both DXA and the adiposity indices, VAI and LAP, are more sensitive methods to evaluate total body fat and fat accumulation in the central abdominal region. It was also observed that as BMI increased, the differences in measurements between women with and without PCOS decreased.

ABSTRACT. In Maranhão State, Brazil, soils are naturally acidic, nutrient-deficient, and prone to cohesion and erosion. Removing the natural cover to establish pastures causes physical, chemical, and biological changes in the soil. Therefore, this study aimed to evaluate the contents and stocks of carbon (C), nitrogen (N), and particle-size fractions of soil organic matter (SOM) in pastures with different years of recovery, and compare them with a secondary forest in the Legal Amazon. Four treatments were evaluated: secondary forest, perennial pasture, and perennial pastures recovered for five years and eight years, both of the latter through corn + brachiaria intercropping. The contents and stocks of total organic carbon, total nitrogen, C, and N from the soil organic matter particle-size fractions, as well as the carbon management indexes (CMI) of the 0.00-0.10, 0.10-0.20, 0.20-0.30, and 0.30-0.40 m layers were evaluated. The perennial pasture environment presented the highest total soil C and N contents; however, when observing the granulometric fractions and CMI, these increases were qualitative in relation to the secondary forest. Pasture recovery over eight years contributed to an improvement of soil quality similar to secondary forest, indicating that an increase in SOM quality, quantity, and recovery time related to increased pasture capacity to accumulate C and N in the soil.

Resumo As lesões traumáticas da aorta (LTA) torácica estão associadas a altas taxas de morbimortalidade. São classificadas de acordo com a extensão do dano, e a angiotomografia computadorizada tem as maiores sensibilidade e especificidade para identificar o grau de lesão e potenciais lesões associadas. As estratégias terapêuticas para LTA são baseadas no tipo de lesão, na extensão e nas lesões associadas. Pode auxiliar na definição de conduta também o grau de estabilidade do paciente, podendo ser manejo cirúrgico convencional, endovascular (TEVAR) ou conservador em casos selecionados. Entre os pacientes com anatomia vascular adequada, a cirurgia endovascular está associada a melhor sobrevida e a menos riscos. O objetivo deste artigo foi descrever uma série de quatro casos acompanhados em serviço terciário, em um estado com poucos serviços de alta complexidade. A terapêutica endovascular foi empregada como método preferencial. Os pacientes apresentaram evolução favorável sem complicações até a alta e encontram-se em acompanhamento ambulatorial.

Abstract Traumatic thoracic aortic injuries (TTAI) are associated with high rates of morbidity and mortality. They are classified according to the extent of damage and computed tomography angiography has the highest sensitivity and specificity for identifying the degree of injury and potential associated lesions. Treatment strategies for TTAI are based on the type and extent of injury and associated lesions. The patient’s degree of stability can also help to define the choice of treatment, which can be conventional or endovascular surgery (EVAR) or even conservative management in selected cases. Among patients with adequate vascular anatomy, endovascular surgery is associated with better survival and fewer risks. The objective of this article is to describe a series of four cases followed up at a tertiary service in a Brazilian state that has few centers that provide high complexity care. Endovascular therapy was employed as the preferred method. All four patients had favorable outcomes, with no complications up to discharge, and are currently in outpatient follow-up.

Abstract Introduction : The scientific production of the areas of physical therapy and occupational therapy presented important growth and international visibility. Objective : To evaluate technical and scientific indicators, in addition to the training of human resources, of scholarship researchers of scientific productivity of CNPq (PQ), in the area of physical therapy and occupational therapy. Methods : A cross-sectional, census and quantitative study was conducted from the Lattes curricula of CNPq researchers with active scholarships in December 2021. The information was extracted through the Lattes Platform of CNPq, including three dimensions of variables for analysis: a) researcher profile; b) scientific production; c) training of human resources. Results : The evaluation included 73 PQ CNPq, in the areas of physical therapy and occupational therapy. The majority were female (n = 42; 57.5%), distributed in 26 different institutions in the country, with the Southeast region being the most prevalent. The largest portion of the PQ completed their doctorate between 11 and 20 years ago (n = 41; 56.2%) and did postdoctoral work (n = 55; 75.3%) abroad (n = 32; 58.2%). The group published 9,486 scientific articles throughout its career, averaging 129.94 scientific articles per PQ. The group of PQ supervised a total of 2,561 undergraduate students, 1,748 master’s and 800 doctoral students. The mean H index of PQ was 19.74 (CI 95% = 18.40-21.11; SD = 5.71; median = 19). Conclusion : The PQ scholarship researchers presented significant scientific production and training of human resources, which confirms the important development of the areas in the last ten years. However, a strong nucleation of this production was observed.

Abstract The emergence of experiences of production and circulation of news content generated by non-journalists is a growing phenomenon, particularly in the last two decades, which causes changes in the media ecosystem, requires the discussion of ethical issues and about trust and credibility, and imposes a set of challenges to traditional journalism. In Brazil, a significant experience in this sense is Onde Tem Tiroteio, created in 2016 as a Facebook fanpage and later transformed into an app. Analyzed here under the methodological prism of virtual ethnography, OTT is constituted as an initiative that, from a process of collaborative production, checking of information, and close relationships between facts and those who report them, acquires journalistic relevance, on the one hand, and demands the deepening of discussions about ethics, credibility, and trust, on the other. At the same time, the profusion of projects such as OTT alerts to the indispensability of traditional journalism to adopt a self-critical look in order to reestablish bonds of trust with society.

Resumen La aparición de experiencias de producción y circulación de contenidos informativos generados por no-periodistas es un fenómeno creciente, sobre todo en las dos últimas décadas, que provoca cambios en el ecosistema de los medios de comunicación, exige el debate sobre cuestiones éticas y sobre la confianza y la credibilidad, e impone un conjunto de retos al periodismo tradicional. En Brasil, una experiencia significativa en este sentido es Onde Tem Tiroteio, creada en 2016 como una fanpage de Facebook y posteriormente transformada en una app. Analizada aquí bajo el prisma metodológico de la etnografía virtual, la OTT se constituye como una iniciativa que, a partir de un proceso de producción colaborativa, de comprobación de la información y de relaciones de proximidad entre los hechos y quienes los relatan, adquiere relevancia periodística, por un lado, y exige la profundización de los debates sobre ética, credibilidad y confianza, por otro. Al mismo tiempo, la profusión de proyectos como OTT alerta sobre la indispensabilidad de que el periodismo tradicional adopte una mirada autocrítica para restablecer los lazos de confianza con la sociedad.

Resumo O surgimento de experiências de produção e circulação de conteúdos noticiosos gerados por não-jornalistas é um fenômeno crescente, particularmente nas últimas duas décadas, que provoca alterações no ecossistema midiático, exige a discussão de questões éticas e sobre confiança e credibilidade, e imputa um conjunto de desafios ao jornalismo tradicional. No Brasil, uma experiência significativa neste sentido é o Onde Tem Tiroteio, criado em 2016 como uma fanpage no Facebook e, posteriormente, transformada em app. Aqui analisado sob o prisma metodológico da etnografia virtual, o OTT constitui-se como uma iniciativa que, a partir de um processo de produção colaborativa, checagem das informações e relações de proximidade entre os fatos e quem os reporta, adquire relevância jornalística, por um lado, e demanda o aprofundamento de discussões sobre ética, credibilidade e confiança, por outro. Ao mesmo tempo, a profusão de projetos como o OTT alerta para a imprescindibilidade de o jornalismo tradicional adotar um olhar autocrítico a fim de reestabelecer laços de confiança com a sociedade.

Abstract The selection of parents to originate promising base populations, as well as the knowledge of the gene effects controlling agronomic traits by means of diallel, are useful to drive genetic gains in Brazilian tropical wheat breeding programs. The goals of this study were to select tropical wheat parents with a high frequency of favorable alleles and segregating populations with high potential to originate superior progenies through partial diallel analysis. Thus, 14 parents were divided in two groups and crossed in a 7 × 7 partial diallel scheme to originate 49 F1 combinations. After obtaining F2 generation, the populations and the parents were evaluated in the field in the summer of 2021. Days for heading, plant height, rust and yellow spot resistance, and grain yield were evaluated. The data were subjected to partial diallel analysis. There were significant effects of general combining ability for all traits. The specific combining ability effect was significant for days for heading and plant height. The additive gene effects were predominant over the non-additive ones. The parents with the highest frequency of favorable alleles for the traits evaluated were selected in each group. Four populations with high genetic potential to originate superior progenies were selected.

ABSTRACT The paper presents a structured approach to address decision-making challenges within the medical clinic service of a mid-sized hospital located in Brazil, using Soft System Methodology (SSM). Its application extends to the medical clinic, a previously unexplored domain within the hospital. Within this context, we introduce a novel conceptual framework for healthcare, wherein we integrate Plan-Do-Check-Act (PDCA) tool into SSM framework. The overarching goal is to rectify the pivotal issue of excessive workload allocation among the medical clinic staff. The developed model effectively addresses this issue by optimizing task allocation. It achieves this by designating primary and auxiliary nursing staff for specific sets of tasks, taking into consideration the necessity for displacement and ensuring a fair distribution of workloads. Furthermore, our model incorporates PDCA into the implementation phase of SSM, thereby establishing a mechanism for ongoing improvement in the initial equilibrium achieved in terms of staff deployment and task distribution.

Recycled crumb rubber can be sustainable used in mortar both to mitigate nature aggregate consumption, reducing environmental pollution, as well, to improve the acoustic and thermal performance of buildings, without damaging its mechanical properties. This paper explores workability, microstructure, mechanical, thermal and acoustic properties considering increasing contents of crumb rubber (0%, 5%, 10%, 15% and 20% replacement, by volume, of fine aggregate). Mortar characterization tests were carried out in the fresh and hardened state. It has been found that replacing the aggregate with scrap tyre rubber reduced the compressive strength on average 12% and 67% and for tensile strength 35% and 53%, for the contents of 10% and 20% respectively, compared to the reference. Furthermore, it was found that the reductions in thermal conductivity reached 16% and 29% and an increase in acoustic attenuation on average 12% and 13%. Moreover, scanning electron microscopy images were analyzed, justifying the mechanical results obtained. Although the experimental results indicated that the workability and mechanical strengths decreased with the increase of rubber replacement rate, the studied mixtures met the standard specifications, and thus suitable for walls and ceilings coating applications, improve the acoustic and thermal performance of buildings and as a sustainable material.

ABSTRACT Objective: To evaluate the effectiveness of the dorsal fixation technique with a cannulated compression screw (CCS) for transverse scaphoid neck fractures. Methods: A case series study was carried out with patients treated with a CSS between April 2014 and May 2021. The main outcome was the healing of the fracture, verified by radiographic evaluation that used images of the wrist in anteroposterior, lateral, radial deviation, ulnar deviation and oblique views, obtained in the postoperative period. Results: Fifty-two patients aged between 15 and 65 years were analyzed, of which 43 (83%) were male. Of the 52 patients, 19 (36.53%) had a right-hand injury and 33 (63.46%) had a left-hand injury. Results were excellent in 47 patients (90.38%); good in 4 patients (7.69%), with reduced mobility compared to contralateral and poor in 1 patient (1.92%), with failure of consolidation and breakage of the synthesis material. In 51 cases (99%) there was bone consolidation at the end of six months. Conclusion: Osteosynthesis with a cannulated compression screw is a safe, effective and promising method for the treatment of scaphoid neck fractures. Level of Evidence IV, Case Series.

RESUMO Objetivo: Avaliar a eficácia da técnica de fixação dorsal com parafuso canulado de compressão (CCS) para fraturas transversas do colo do escafoide. Métodos: Foi realizado um estudo de série de casos com pacientes tratados com CSS entre abril de 2014 e maio de 2021. O desfecho principal foi a consolidação da fratura, verificada por meio da avaliação radiográfica das imagens do punho em anteroposterior, perfil, desvio radial, desvio ulnar e oblíquo obtidas no pós-operatório. Resultados: Foram analisados 52 pacientes com idade entre 15 e 65 anos, sendo 43 (83%) do sexo masculino. Dos 52 pacientes, 19 (36,53%) tinham lesão na mão direita e 33(63,46%) na mão esquerda. Os resultados foram excelentes em 47 dos pacientes (90,38%); bons em quatro (7,69%), com mobilidade reduzida comparada ao membro contralateral; e ruim em um (1,92%), com falha da consolidação e quebra do material de síntese. Em 51 casos (99%) houve consolidação óssea ao final de seis meses. Conclusão: A osteossíntese com parafuso canulado de compressão é um método seguro, eficaz e promissor para o tratamento das fraturas no colo do escafoide. Nível de Evidência IV, Série de Casos.

ABSTRACT The present study aimed to assess the precision of oxygen uptake with heart rate regression during treadmill running in highly trained runners. Twenty national and international level male runners were divided into two equal groups. Group A was formed of 10 sprinters (31.5± 4.7 years, height 1.74± 0.04 m and mass 61.8± 5.2 kg), and group B comprised 10 endurance runners (25.7± 4.5 years, height 1.77± 0.08 m and mass 71.2± 5.8 kg). Each participant performed six min bouts at a constant velocity on a level treadmill, with each bout at an increased running velocity. The starting velocity was 3.33 m·s-1, with a 0.56 m·s-1 increase in each subsequent bout. VO2 and HR were measured during all runs. Mean peak VO2 and mean peak HR for Group A were, respectively, 71.7± 7.0 mL·kg-1·min-1 and 179.8± 12.7 beats·min-1, while for Group B were 67.3± 4.9 mL·kg-1·min-1 and 198.2± 9.8 beats·min-1. The linearity of the regressions between VO2 and HR in both groups was very high (R2= 0.97 and R2=0.76) with small standard errors of regression. Despite a stronger correlation in endurance-trained athletes, the results of the present study indicate that it is possible to use HR as an indicator of exercise intensity in individuals trained in both speed and longer distances.

Abstract Objective: There are few studies on long-latency auditory evoked potential (P300) in people with hearing loss who use a cochlear implant. Central auditory system evaluation with behavioral and electrophysiological tests is believed to help understand the neuroplasticity mechanisms involved in auditory functioning after cochlear implant surgery. This study investigated the electrophysiological processing of cortical level acoustic signals in a group of 21 adult individuals with postlingual bilateral severe-to-profound hearing loss who were submitted to cochlear implant surgery. Methods: Data were collected in three phases: pre-cochlear implant surgery, at cochlear implant activation, and 6 months after surgery. P300 measures were also registered during all phases. Tone-burst and speech stimuli were used to elicit P300 and were presented in free field. Results: Mean P3 component latency with tone-burst and speech stimuli were 352.9 and 321.9 ms in the pre-cochlear implant phase, 364.9 and 368.7 ms in the activation phase, 336.2 and 343.6 ms 6 months after the surgery. The P3 component mean latency values using tone-burst at activation were significantly different from those 6 months after cochlear implant. They were also significantly different using speech, between pre-cochlear implant and activation phases. Lower P3 component latency occurred 6 months after cochlear implant activation with tone-burst and pre-cochlear implant with speech stimulus. There was a weak correlation between mean P3 component latency with speech stimulus and time of hearing loss. There was no difference in amplitude between phases or in the comparison with the other variables. Conclusion: There were changes in P3 component latency during the period assessed, for both speech and pure-tone stimuli, with increased latency in the activation phase and similar lower results in the two other phases, Pre-CI and 6 months after CI use. Mean amplitude measures did not vary in the three phases.

ABSTRACT Introduction: Eyelid xanthelasma is the most common form of cutaneous xanthoma, characterized by yellowish patches on the eyelid’s skin. Despite being a benign condition and not presenting with functional limitations, it is an important aesthetic complaint that impacts the patient’s social and emotional life. There are clinical therapeutic options, but the most widespread approach is the surgical approach with excision of the lesions, a simple procedure with few complications and lower local recurrence rates. This study aims to describe the surgical treatment of palpebral xanthelasma, to assess postoperative patient satisfaction and post-surgical recurrence rates. Methods: This is a retrospective study with a sample of 25 patients undergoing surgical treatment of eyelid xanthelasmas. Postoperative follow-up was performed at intervals of 7 days, 30 days, 90 days and 12 months with an interview, physical examination and application of a questionnaire that included the identification of local recurrences, postoperative complications and satisfaction with the aesthetic result. Results: Four patients evolved with local recurrence, and only two expressed dissatisfaction with the aesthetic result after the outcome. No patient who underwent surgical resection of lesions associated with autograft recurrence or dissatisfaction with the aesthetic result was observed. Conclusions: Surgical treatment as the first option in the therapeutic approach of eyelid xanthelasmas should be considered, given the aesthetic and psychological impact of such a condition. It is a simple technique, easy to apply and reproducible, effective, and safe, with relevant satisfaction rates and low recurrences.

RESUMO Introdução: O xantelasma palpebral é a forma mais comum de xantoma cutâneo, caracterizado por placas amareladas localizadas na pele das pálpebras. Apesar de ser uma condição benigna e não cursar com limitação funcional, é uma importante queixa estética que tem impacto na vida social e emocional do portador. Existem opções terapêuticas clínicas, mas a abordagem mais difundida é a cirúrgica com excisão das lesões, procedimento simples, com poucas complicações e menores taxas de recidivas locais. O objetivo deste estudo é descrever o tratamento cirúrgico do xantelasma palpebral, avaliar a satisfação dos pacientes no pós-operatório e as taxas de recidivas pós-cirúrgicas. Métodos: Trata-se de um estudo retrospectivo realizado com uma amostra de 25 pacientes submetidos a tratamento cirúrgico de xantelasmas palpebrais. O acompanhamento pós-operatório foi realizado em intervalos de 7 dias, 30 dias, 90 dias e 12 meses com entrevista, exame físico e aplicação de questionário que contemplaram identificação de recidivas locais, complicações pós-operatórias e satisfação com o resultado estético. Resultados: Quatro pacientes evoluíram com recidiva local e apenas dois pacientes manifestaram insatisfação com o resultado estético após o desfecho final. Em nenhum paciente submetido a ressecção cirúrgica das lesões associadas à autoenxertia foi observada recorrência ou insatisfação com o resultado estético. Conclusões: O tratamento cirúrgico como primeira opção na abordagem terapêutica dos xantelasmas palpebrais deve ser considerado, visto o impacto estético e psicológico de tal afecção. É uma técnica simples, de fácil aplicação e reprodutibilidade, eficaz, segura, com relevantes taxas de satisfação e baixa ocorrência de recidivas.
