Abstract Objective To evaluate the safety and reproducibility of the surgery for unstable slipped capital femoral epiphysis (SCFE) through the modified Dunn technique in a single center cohort from Brazil. Methods We retrospectively analyzed a cohort of patients submitted to this procedure by a single surgeon who was a hip preservation specialist. Demographic data and radiographic angles were evaluated for the relative risk (RR) of avascular necrosis (AVN) using a log-binomial regression model with simple and random effects. Results Among the 30 patients (30 hips) with a mean age of 11.79 years at the time of the operation, there were 17 boys and 18 left hips, which were operated on in a mean of 11.5 days after the slip. The mean follow-up was of 38 months. The preoperative Southwick angle averaged 60.69° against 4.52° postoperatively (p< 0.001). A larger preoperative slip angle was associated with the development of AVN (RR: 1.05; 95% confidence interval [95%CI]: 1.02–1.07; p< 0.01). The overall AVN rate was of 26.7%. Function was good or excellent in 86% of uncomplicated hips, and poor in 87.5% of the partients who developed AVN, as graded by the Harris Hip Score. There was no statistical relationship between epiphyseal bleeding and AVN development (p= 0.82). Conclusion The modified Dunn technique is associated with restoration of the femoral alignment and function after unstable SCFE, when uncomplicated. Moreover, it was shown to be reproducible in our population, with a rate of 26% of femoral head necrosis.

Resumo Objetivo Avaliar a segurança e a reprodutibilidade da cirurgia para escorregamento da epífise femoral proximal (EEPF) com instabilidade por meio da técnica de Dunn modificada em uma coorte unicêntrica no Brasil. Métodos Analisamos de forma retrospectiva uma coorte de pacientes submetidos a esse procedimento por um único cirurgião especialista em preservação do quadril. Avaliamos os dados demográficos e os ângulos radiográficos quanto ao risco relativo (RR) de necrose avascular (NAV) por meio do modelo de regressão log-binomial com efeitos simples e aleatórios. Resultados Entre os 30 pacientes (30 quadris) com idade média de 11,79 anos no momento da cirurgia, havia 17 meninos e 18 quadris esquerdos. O procedimento ocorreu em média 11,5 dias após o escorregamento. O tempo médio de acompanhamento foi de 38 meses. O ângulo de Southwick pré-operatório foi, em média, de 60,69° contra 4,52° após o procedimento (p< 0,001). O maior ângulo de escorregamento pré-operatório foi associado ao desenvolvimento de NAV (RR: 1,05; intervalo de confiança de 95% [IC95%]: 1,02–1,07; p< 0,01). A frequência geral de NAV foi de 26,7%. De acordo com a Escala de Quadril de Harris (Harris Hip Score), a função foi boa ou excelente em 86% dos quadris sem complicações, e ruim em 87,5% dos casos com NAV. Não houve relação estatística entre sangramento epifisário e desenvolvimento de NAV (p= 0,82). Conclusão A técnica de Dunn modificada restaura o alinhamento femoral e a função articular após o EEPF com instabilidade na ausência de complicações. Além disso, mostrou-se passível de reprodução em nossa população, com frequência de necrose da cabeça femoral de 26%.

Abstract: En Es Pt

The objective of this study was to evaluate the effect of α-lipoic acid on in vitro maturation and of l-arginine on in vitro fertilization of oocytes for in vitro production of sheep embryos. Thus, the ovaries were collected at a local slaughterhouse and the oocytes collected by the method of follicular aspiration with a vacuum pump were divided equally into five maturation groups: CON, without addition of antioxidant; CIS group, with cysteamine as an antioxidant source; and the groups ALA5, ALA10 and ALA20, containing concentrations of 5.0, 10.0 and 20.0 µM of ALA. After 24h of maturation, the oocytes were evaluated concerning occurrence and degrees of expansion of the cumulus cells. The oocytes of the best IVM group were destinated for in vitro fertilization (IVF). The selected and capacitated sperm were included in five groups: CON, without addition of capacitator agent; HEP group, with heparin as a capacitator source; and ARG5, ARG10 and ARG20 groups, where IVF occurred in the same HEP medium, replacing heparin with 5 mM, 10 mM and 20 mM L-arginine, respectively. The results were expressed as a percentage and the variables of cumulus cell expansion and number of cleaved structures were compared using the chi-square test in Epi Info software (Epi Info 7.2.5, Atlanta, GA, USA, 2021). Results were considered significant when P < 0.05. Regarding the expansion of cumulus cells all groups showed 100% expansion, on the total expansion category of COCs it was observed that ALA5 and ALA20 groups did not present the same proportion of COCs with total expansion as CIS group. After in vitro fertilization (IVF), there were no statistical differences in relation to the cleaved structures between CON, HEP, ARG5 and ARG10 groups. However, it was also observed that the use of 20.0 mM of L-arginine reduced the percentage of cleaved structures when compared to the ARG10 group (P<0.05).

El objetivo de este trabajo fue evaluar el efecto del ácido α-lipoico en la maduración in vitro y la l-arginina en la fecundación in vitro de ovocitos para la producción in vitro de embriones ovinos. Así, se recolectaron ovocitos de ovarios obtenidos de mataderos mediante el método de aspiración folicular con bomba de vacío, los cuales se dividieron en cinco grupos de maduración: CON, sin adición de antioxidante, grupo CIS, con cisteamina como fuente antioxidante y los grupos ALA5, ALA10 y ALA20, que contienen concentraciones de 5, 10 y 20 µM de ácido α-lipoico. Después de 24 h de maduración, se evaluó la aparición y el grado de expansión de las células del cúmulo en los ovocitos. Los ovocitos del mejor grupo MIV fueron destinados a fecundación in vitro (FIV), siendo por tanto incluidos en gotas con medio de fecundación in vitro, junto con los espermatozoides seleccionados y capacitados, resultando en los siguientes grupos: CON, sin adición de agente capacitador; grupo HEP, con heparina como fuente de condensadores; y los grupos ARG5, ARG10 y ARG20, donde se produjo la FIV en el mismo medio HEP, reemplazando la heparina por L-arginina 5, 10 y 20 mM, respectivamente. Los resultados se expresaron en porcentajes y las variables expansión celular del cúmulo y número de estructuras escindidas se compararon mediante la prueba chicuadrado del software Epi Info (Epi Info 7.2.5, Atlanta, GA, USA, 2021). Los resultados se consideraron significativos cuando P lt; 0,05. En cuanto a la expansión de las células del cúmulo, todos los grupos mostraron 100% de expansión. Evaluando los grados de expansión de las células del cúmulo, en la categoría de expansión total, se observó que los grupos ALA5 y ALA20 presentaron la misma proporción de CCO con expansión total que el grupo CIS (Plt;0.05), sin embargo se observa que hay una tendencia a la baja de las estructuras con plena expansión cuando se utilizan antioxidantes. En cuanto a las estructuras escindidas, fue posible identificar que no hubo diferencias estadísticas en relación a las estructuras escindidas, entre los grupos CON, HEP, ARG5 y ARG10. Sin embargo, también se observó que el uso de Larginina 20 mM redujo el porcentaje de estructuras escindidas en comparación con el grupo ARG10 (Plt;0.05).

O objetivo deste trabalho foi avaliar o efeito do ácido α-lipóico na maturação in vitro e da l-arginina na fertilização in vitro de oócitos para produção in vitro de embriões ovinos. Desta forma, foram realizadas colheitas de oócitos oriundos de ovários obtidos em abatedouro através do método de aspiração folicular com bomba de vácuo, que foram divididos em cinco grupos de maturação: CON, sem adição de antioxidante, grupo CIS, com cisteamina como fonte antioxidante e os grupos ALA5, ALA10 e ALA20, contendo as concentrações de 5, 10, e 20 µM de ácido α-lipóico. Após 24h de maturação, os oócitos foram avaliados quanto à ocorrência e grau de expansão das células do cumulus. Os oócitos do melhor grupo MIV foram destinados à fertilização in vitro (FIV), sendo, portanto, incluídos em gotas com meio de fertilização in vitro, juntamente com os espermatozoides selecionados e capacitados, resultando nos seguintes grupos: CON, sem adição de capacitador agente; grupo HEP, com heparina como fonte de capacitor; e grupos ARG5, ARG10 e ARG20, onde a FIV ocorreu no mesmo meio HEP, substituindo a heparina por L-arginina 5, 10 e 20 mM, respectivamente. Os resultados foram expressos em porcentagem e as variáveis de expansão das células do cumulus e número de estruturas clivadas foram comparadas por meio do teste qui-quadrado do software Epi Info (Epi Info 7.2.5, Atlanta, GA, EUA, 2021). Os resultados foram considerados significativos quando P lt; 0,05. Em relação à expansão das células do cumulus, todos os grupos apresentaram 100% de expansão. Avaliando os graus de expansão das células do cumulus, na categoria de expansão total observou-se que os grupos ALA5 e ALA20 apresentaram a mesma proporção de CCO com expansão total que o grupo CIS (Plt;0,05), porém se observa que há uma tendência de queda de estruturas com expansão total quando os antioxidantes foram utilizados. Em relação às estruturas clivadas, foi possível identificar que não houve diferenças estatísticas em relação às estruturas clivadas, entre os grupos CON, HEP, ARG5 e ARG10. Contudo, também foi observado que o uso de 20 mM de L-arginina reduziu o percentual de estruturas clivadas quando comparado ao grupo ARG10 (Plt;0,05).

Abstract Background Professional soccer athletes are exposed to repetitive head impacts and are at risk of developing chronic traumatic encephalopathy. Objective To evaluate regional brain glucose metabolism (rBGM) and gray matter (GM) volume in retired soccer players (RSPs). Methods Male RSPs and age and sex-matched controls prospectively enrolled between 2017 and 2019 underwent neurological and neuropsychological evaluations, brain MRI and [18F]FDG-PET in a 3.0-Tesla PET/MRI scanner. Visual analysis was performed by a blinded neuroradiologist and a blinded nuclear physician. Regional brain glucose metabolism and GM volume were assessed using SPM8 software. Groups were compared using appropriate statistical tests available at SPM8 and R. Results Nineteen RSPs (median [IQR]: 62 [50–64.5] years old) and 20 controls (60 [48–73] years old) were included. Retired soccer players performed worse on mini-mental state examination, digit span, clock drawing, phonemic and semantic verbal fluency tests, and had reduced rBGM in the left temporal pole (pFDR = 0.008) and the anterior left middle temporal gyrus (pFDR = 0.043). Semantic verbal fluency correlated with rBGM in the right hippocampus, left temporal pole, and posterior left middle temporal gyrus (p ≤ 0.042). Cray matter volume reduction was observed in similar anatomic regions but was less extensive and did not survive correction for multiple comparisons (pFDR ≥ 0.085). Individual [18F]FDG-PET visual analysis revealed seven RSPs with overt hypometabolism in the medial and lateral temporal lobes, frontal lobes, and temporoparietal regions. Retired soccer players had a higher prevalence of septum pellucidum abnormalities on MRI. Conclusion Retired soccer players had reduced rBCM and CM volume in the temporal lobes and septum pellucidum abnormalities, findings possibly related to repetitive head impacts.

Resumo Antecedentes Jogadores profissionais de futebol estão expostos a impactos cranianos repetitivos e ao risco de desenvolver encefalopatia traumática crônica. Objetivo Avaliar o metabolismo glicolítico cerebral regional (MCCr) e o volume de substância cinzenta (vSC) em jogadores de futebol aposentados (JFAs). Métodos Jogadores de futebol aposentados masculinos e controles pareados por idade e sexo foram incluídos prospectivamente entre 2017 e 2019. Foram realizadas avaliações neurológica e neuropsicológica, ressonância magnética (RM) e [18F]FDG-PET cerebrais (3.0-Tesla PET/RM). As imagens foram analisadas visualmente por um neurorradiologista e um médico nuclear cegos ao grupo de cada participante. O metabolismo glicolítico cerebral regional e o vSC foram avaliados através do programa SPM8. Os grupos foram comparados através de testes estatísticos apropriados disponíveis em SPM8 e R, de acordo com a distribuição e o tipo dos dados. Resultados Dezenove JFAs (mediana [IIQ]: 62 [50–64.5] anos) e 20 controles (60 [48–73] anos) foram incluídos. Os JFAs tiveram pior desempenho no mini-exame do estado mental e nos testes de dígitos, desenho do relógio, fluência verbal e fluência semântica e apresentaram MCCr significativamente reduzido no polo temporal e no giro temporal médio anterior esquerdos. Fluência semântica (animais) apresentou correlação positiva com MCCr no hipocampo direito, no polo temporal esquerdo e no aspecto posterior do giro temporal médio esquerdo. Menor vSC foi observado nas mesmas regiões, porém este achado não sobreviveu à correção para comparações múltiplas. Análise individual do [18F]FDG-PET cerebral revelou sete JFAs com claro hipometabolismo nas faces medial e lateral dos lobos temporais, nos lobos frontais e nas regiões temporoparietais. Os JFAs apresentaram ainda maior prevalência de anormalidades do septo pelúcido. Conclusão Os JFAs apresentam MCCr e vSC reduzidos nos lobos temporais, além de anormalidades do septo pelúcido, achados possivelmente relacionados a impactos cranianos repetitivos.

Resumo O estudo tem por objetivo identificar em que medida e de que forma os princípios, diretrizes e métodos propostos pela Reforma Psiquiátrica Brasileira (RPB) estão presentes na formação dos psiquiatras em programas de Residência Médica. Trata-se de estudo qualitativo que investiga conteúdos e experiências promovidos durante a formação em programas de Residência Médica de Psiquiatria no Brasil. Foram entrevistados 16 sujeitos em quatro instituições públicas de formação, sendo dois programas centrados em hospitais-escola e outros dois em modelos integrados a serviços da Rede de Atenção Psicossocial. Os resultados do estudo permitem sustentar que, apesar de todos os programas remeterem a princípios da RPB em seus conteúdos teóricos, as oportunidades de prática dos modelos integrados dialogam mais diretamente com a experiência da RPB. Entre outros resultados relevantes, destacam-se: preocupação com o cuidado integral, não centrado apenas nos diagnósticos e sintomas, mas na singularidade e no andar a vida dos sujeitos; crítica à medicalização, seja na forma do uso abusivo de medicação, seja como interferência em demandas não especificamente médicas; importância de experiências interdisciplinares em equipes multiprofissionais e uma proposta da superação de uma cultura manicomial que vai além da institucionalidade dos serviços, mas que opera nos processos cotidianos de normalização social.

Abstract The study aims to identify to what extent and how the principles, guidelines and methods proposed by the Brazilian Psychiatric Reform (BPR) are present in the training of psychiatrists in medical residency programs. This is a qualitative study that investigates contents and experiences promoted during training in psychiatric medical residency programs in Brazil. A total of 16 subjects were interviewed in four public training institutions, two programs centered on school hospitals and two in models integrated with psychosocial care network services. The results of the study allow us to argue that, although all programs refer to BPR principles in their theoretical contents, the services integrated programs seems to promote a closer dialogue with the BPR experience. Among other relevant results, the following stand out: concern with comprehensive care, not focused only on diagnoses and symptoms, but on the singularity and ways of life of the subjects; criticism of medicalization, either in the form of abuse of medication, or as interference in non-specifically medical demands; relevance of interdisciplinary experiences in multidisciplinary teams and the aim to overcome a manicomial culture that goes beyond the institutionality of services, but that operates in the daily processes of social normalization.

Abstract Objective: To assess factors associated with emotional changes and Hyperactivity/Inattention (HI) motivated by COVID-19 quarantine in adolescents with immunocompromising diseases. Methods: A cross-sectional study included 343 adolescents with immunocompromising diseases and 108 healthy adolescents. Online questionnaires were answered including socio-demographic data and self-rated healthcare routine during COVID-19 quarantine and validated surveys: Strengths and Difficulties Questionnaire (SDQ), Pittsburgh Sleep Quality Index (PSQI), Pediatric Quality of Life Inventory 4.0 (PedsQL4.0). Results: The frequencies of abnormal emotional SDQ scores from adolescents with chronic diseases were similar to those of healthy subjects (110/343 [32%] vs. 38/108 [35%], p = 0.548), as well as abnormal hyperactivity/inattention SDQ scores (79/343 [23%] vs. 29/108 [27%], p = 0.417). Logistic regression analysis of independent variables associated with abnormal emotional scores from adolescents with chronic diseases showed: female sex (Odds Ratio [OR = 3.76]; 95% Confidence Interval (95% CI) 2.00–7.05; p < 0.001), poor sleep quality (OR = 2.05; 95% CI 1.08–3.88; p = 0.028) and intrafamilial violence during pandemic (OR = 2.17; 95% CI 1.12–4.19; p = 0.021) as independently associated with abnormal emotional scores, whereas total PedsQL score was inversely associated with abnormal emotional scores (OR = 0.95; 95% CI 0.93–0.96; p < 0.0001). Logistic regression analysis associated with abnormal HI scores from patients evidenced that total PedsQL score (OR = 0.97; 95% CI 0.95–0.99; p = 0.010], changes in medical appointments during the pandemic (OR = 0.39; 95% CI 0.19–0.79; p = 0.021), and reliable COVID-19 information (OR = 0.35; 95% CI 0.16–0.77; p = 0.026) remained inversely associated with abnormal HI scores. Conclusion: The present study showed emotional and HI disturbances in adolescents with chronic immunosuppressive diseases during the COVID-19 pandemic. It reinforces the need to promptly implement a longitudinal program to protect the mental health of adolescents with and without chronic illnesses during future pandemics.

ABSTRACT Objective The incidence of thrombotic events and acute kidney injury is high in critically ill patients with COVID-19. We aimed to evaluate and compare the coagulation profiles of patients with COVID-19 developing acute kidney injury versus those who did not, during their intensive care unit stay. Methods Conventional coagulation and platelet function tests, fibrinolysis, endogenous inhibitors of coagulation tests, and rotational thromboelastometry were conducted on days 0, 1, 3, 7, and 14 following intensive care unit admission. Results Out of 30 patients included, 13 (43.4%) met the criteria for acute kidney injury. Comparing both groups, patients with acute kidney injury were older: 73 (60-84) versus 54 (47-64) years, p=0.027, and had a lower baseline glomerular filtration rate: 70 (51-81) versus 93 (83-106) mL/min/1.73m2, p=0.004. On day 1, D-dimer and fibrinogen levels were elevated but similar between groups: 1780 (1319-5517) versus 1794 (726-2324) ng/mL, p=0.145 and 608 (550-700) versus 642 (469-722) g/dL, p=0.95, respectively. Rotational thromboelastometry data were also similar between groups. However, antithrombin activity and protein C levels were lower in patients who developed acute kidney injury: 82 (75-92) versus 98 (90-116), p=0.028 and 70 (52-82) versus 88 (78-101) µ/mL, p=0.038, respectively. Mean protein C levels were lower in the group with acute kidney injury across multiple time points during their stay in the intensive care unit. Conclusion Critically ill patients experiencing acute kidney injury exhibited lower endogenous anticoagulant levels. Further studies are needed to understand the role of natural anticoagulants in the pathophysiology of acute kidney injury within this population.

Abstract: En | Text: En | PDF: En

ABSTRACT Pulmonary aspiration of gastric residues during anesthesia is a potentially fatal complication for which no specific treatment is available. The primary way to prevent its occurrence in the context of elective surgeries is adherence to fasting protocols. However, some clinical conditions can prolong the gastric emptying time, and the risk of aspiration may exist despite adequate fasting. Recognizing the risk factors for gastroparesis allows the adoption of preventive methods and is the primary way to reduce morbidity and mortality from pulmonary aspiration. In this scenario, the anesthesiologist can investigate the gastric content by using ultrasound, adjust the anesthetic technique, and even postpone elective surgeries. Here, we describe incidental computed tomography finding of solid contents in the stomach of a patient without prior identification of the risk factors for gastroparesis. The patient underwent elective renal nodule ablation under general anesthesia after fasting for 9 hours. During the procedure, solid contents in the stomach were noted on computed tomography. Subsequently, it was discovered that the patient had been using semaglutide for 6 days and had not disclosed this information. Semaglutide use may represent a new and significant risk factor for anesthesia-related pulmonary aspiration. Until studies provide information on the appropriate perioperative management of patients using semaglutide, anesthesiologists need to adopt preventive measures to avoid aspiration. Awareness of this potential association and open communication among patients, physicians, and anesthesia teams are essential for enhancing patient safety.

Abstract: En | Text: En | PDF: En

Objective: Positron emission tomography (PET) allows in vivo evaluation of molecular targets in neurodegenerative diseases, such as Alzheimer’s disease. Mild cognitive impairment is an intermediate stage between normal cognition and Alzheimer-type dementia. In vivo fibrillar amyloid-beta can be detected in PET using [11C]-labeled Pittsburgh compound B (11C-PiB). In contrast, [18F]fluoro-2-deoxy-d-glucose (18F-FDG) is a neurodegeneration biomarker used to evaluate cerebral glucose metabolism, indicating neuronal injury and synaptic dysfunction. In addition, early cerebral uptake of amyloid-PET tracers can determine regional cerebral blood flow. The present study compared early-phase 11C-PiB and 18F-FDG in older adults without cognitive impairment, amnestic mild cognitive impairment, and clinical diagnosis of probable Alzheimer’s disease. Methods: We selected 90 older adults, clinically classified as healthy controls, with amnestic mild cognitive impairment, or with probable Alzheimer’s disease, who underwent an 18F-FDG PET, early-phase 11C-PiB PET and magnetic resonance imaging. All participants were also classified as amyloid-positive or -negative in late-phase 11C-PiB. The data were analyzed using statistical parametric mapping. Results: We found that the probable Alzheimer’s disease and amnestic mild cognitive impairment group had lower early-phase 11C-PiB uptake in limbic structures than 18F-FDG uptake. The images showed significant interactions between amyloid-beta status (negative or positive). However, early-phase 11C-PiB appears to provide different information from 18F-FDG about neurodegeneration. Conclusions: Our study suggests that early-phase 11C-PiB uptake correlates with 18F-FDG, irrespective of the particular amyloid-beta status. In addition, we observed distinct regional distribution patterns between both biomarkers, reinforcing the need for more robust studies to investigate the real clinical value of early-phase amyloid-PET imaging.

RESUMO A cetamina é única entre os anestésicos e analgésicos. A droga é um anestésico geral de ação rápida que produz um estado anestésico caracterizado por analgesia profunda, reflexos faríngeolaríngeos preservados, tônus músculo esquelético normal ou ligeiramente aumentado, estimulação cardiovascular e respiratória e, ocasionalmente, insuficiência respiratória transitória e mínima. Estudos demonstraram a eficácia de seu uso em anestesia, na dor, em cuidados paliativos e em cuidados intensivos. Recentemente, tem sido empregada para dores pós-operatórias e crônicas, como coadjuvante em psicoterapia, como tratamento para depressão e transtorno de estresse pós-traumático, como sedativo para procedimentos cirúrgicos e como tratamento para condições clínicas respiratórias e/ou neurológicas. Apesar de ser um medicamento seguro e amplamente utilizado, muitos médicos, como intensivistas e emergencistas, não estão cientes das aplicações clínicas atuais da cetamina. O objetivo desta revisão bibliográfica narrativa é apresentar aspectos teóricos e práticos das aplicações clínicas da cetamina em ambientes de unidade de terapia intensiva e serviços de emergência.

ABSTRACT Ketamine is unique among anesthetics and analgesics. The drug is a rapid-acting general anesthetic that produces an anesthetic state characterized by profound analgesia, preserved pharyngeal-laryngeal reflexes, normal or slightly enhanced skeletal muscle tone, cardiovascular and respiratory stimulation, and occasionally a transient and minimal respiratory depression. Research has demonstrated the efficacy of its use on anesthesia, pain, palliative care, and intensive care. Recently, it has been used for postoperative and chronic pain, as an adjunct in psychotherapy, as a treatment for depression and posttraumatic stress disorder, as a procedural sedative, and as a treatment for respiratory and/or neurologic clinical conditions. Despite being a safe and widely used drug, many physicians, such as intensivists and those practicing in emergency care, are not aware of the current clinical applications of ketamine. The objective of this narrative literature review is to present the theoretical and practical aspects of clinical applications of ketamine in intensive care unit and emergency department settings.

ABSTRACT The germplasm characterization and the analysis of genetic divergence are fundamental requirements to determine the genetic diversity available and peppers have considerable variability not most explored and quantified. Thus, the aim of this study was to characterize morphological and agronomically pepper accessions and their genetic divergence. The experiment was conducted in a greenhouse of the Department of Agronomy of the Universidade Federal Rural de Pernambuco, Recife, between the months of December 2014 to June 2015. Thirteen pepper accessions in pots were sown, the experimental design was a randomized block with six replications, and the experimental unit consisted of three pots. Seedling, leaves, plant and fruit characteristics were evaluated. For the analysis of genetic divergence, the Mahalanobis distance and the UPGMA method were used. It was observed the formation of three distinct groups, being fruit width the trait that most contributed to the genetic discrimination of the accessions. Group I presented larger fruits, Group II showed heavier and wider fruits and Group III had mostly smaller, lighter and thinner fruits. There were differences for most of the evaluated characteristics, showing great morphological and agronomic variability among the accessions. The peppers have a high potential to be exploited in breeding.

Resumo A osteotomia Le Fort I é amplamente utilizada em cirurgia ortognática para corrigir as deformidades maxilares. No entanto, esse tipo de osteotomia pode estar relacionado ao aumento da largura da base alar. Os objetivos do presente estudo foram comparar duas técnicas de sutura da base alar após a realização da osteotomia Le Fort I, bem como observar qual tipo apresenta melhor resultado no controle do alargamento da base alar após o reposicionamento maxilar em cirurgia ortognática. Foi realizado um ensaio clínico randomizado com 40 pacientes alocados aleatoriamente em dois grupos de intervenção: grupo 1 - pacientes submetidos à técnica de sutura interna e grupo 2 - pacientes submetidos à técnica de externa. Dos 40 pacientes, 65% eram do sexo feminino e 35% do masculino. A média de idade dos pacientes foi de 30,25 no grupo I e 28,6 no grupo II. Houve aumento da largura da base alar em ambos os grupos, com diferença significativa entre as médias (P <0,001). Foi possível comparar a evolução das médias da largura da base alar entre o grupo I e o grupo II. Assim, observou-se que a técnica externa (grupo II) controlou melhor a largura da base alar após a osteotomia Le Fort I. Não foi possível relacionar o alargamento da base alar com o tipo de movimentação maxilar realizado (P> 0,05). No geral, a sutura da base alar é um componente essencial das osteotomias Le Fort para controlar o alargamento da base alar. Nesse estudo, a técnica externa foi mais eficaz quando comparada à técnica interna no controle do alargamento da largura da base alar.

Abstract Le Fort I osteotomy is widely used in orthognathic surgery to correct maxillary deformities. However, this osteotomy may be related with the increase of alar base width. The aims of the present study were to compare two alar cinch suture after Le Fort I osteotomy and observe which type presents a better result in controlling the enlargement of the alar base after maxillary repositioning in orthognathic surgery. A randomized clinical trial was carried out with 40 patients randomly assigned in two intervention groups: group 1 - patients submitted to internal suture and group 2 - patients submitted to external suture. Of the 40 patients, 65% were female and 35% were male. The mean age of the patients was 30,25 in group I and 28,6 in group II. There was an increase in the alar base width in both groups, with significant difference between the means (P < 0,001). It was possible to compare the evolution of the means of the alar base width between group I and group II. Thus, it was observed that the external technique (group II) better controlled alar base width after Le Fort I osteotomy. It was not possible to relate the enlargement of the alar cinch with maxillary movement performed (P > 0,05). Overall, alar base cinch suture is an essential component of Le Fort osteotomies to control the alar base width. In this study, the external technique was more effective when compared to the internal technique in controlling the enlargement of the alar base width.

Resumo Introdução: Displasia fibrosa é uma desordem benigna, na qual o osso é substituído por fibrose e trabeculado ósseo imaturo, com distribuição semelhante entre sexos, mais comum nas primeiras décadas de vida. O acometimento do osso temporal pela displasia fibrosa é raro, não há consenso se é mais comum nas formas monostóticas ou poliostóticas. Estenose do meato acústico externo e disacusia condutiva são as manifestações mais comuns. Colesteatoma é também uma complicação comum e o acometimento da cápsula ótica incomum. O tratamento cirúrgico está indicado para controle de dor ou disacusia, otorreia, colesteatoma, deformidade. Objetivos: Descrever a experiência clínica de hospital terciário de referência com casos de displasia fibrosa do osso temporal. Método: Amostragem dos pacientes com diagnóstico de displasia fibrosa do osso temporal, confirmado pela tomografia, atendidos nos ambulatórios de otologia e otorrinolaringologia pediátrica, entre 2015 e 2018. As variáveis avaliadas foram idade, gênero, lateralidade, estenose do meato acústico externo, deformidade, perda auditiva, presença de colesteatoma secundário de meato acústico externo, extensão da lesão e conduta adotada. Resultados: Foram incluídos cinco pacientes, quatro do sexo feminino e um masculino, de 13-34 anos. Três apresentaram a forma poliostótica da displasia fibrosa do osso temporal e dois a forma monostótica. Quatro apresentaram deformidade local e estenose do meato acústico externo, dois desses evoluíram com colesteatoma. Todos manifestaram algum grau de comprometimento auditivo. Todos apresentaram cápsula ótica preservada na tomografia. Duas pacientes estão em observação clínica; duas foram submetidas a timpanomastoidectomia devido a colesteatoma secundário; um foi submetido a ressecção da lesão para controle de progressão da disacusia. Conclusão: Foram descritos cinco casos de displasia fibrosa do osso temporal, desordem rara para a qual o otologista deve estar atento.

Abstract Introduction: Fibrous dysplasia is a benign disorder, in which normal bone is replaced by fibrosis and immature bone trabeculae, showing a similar distribution between the genders, and being more prevalent in the earlier decades of life. Fibrous dysplasia of the temporal bone is a rare condition, and there is no consensus as to whether it is more common in monostotic or polyostotic forms. External auditory meatus stenosis and conductive dysacusis are the most common manifestations, with cholesteatoma being a common complication, whereas the involvement of the otic capsule is an unusual one. Surgical treatment is indicated to control pain or dysacusis, otorrhea, cholesteatoma, and deformity. Objectives: To describe the clinical experience of a tertiary referral hospital with cases of fibrous dysplasia of the temporal bone. Methods: Sampling of patients diagnosed with fibrous dysplasia of the temporal bone, confirmed by tomography, treated at the pediatric otology and otorhinolaryngology outpatient clinics, between 2015 and 2018. The assessed variables were age, gender, laterality, external auditory meatus stenosis, deformity, hearing loss, presence of secondary cholesteatoma of the external auditory meatus, lesion extension and management. Results: Five patients were included, four females and one male, with age ranging from 13 to 34 years. Three had the polyostotic form and two the monostotic form of fibrous dysplasia of the temporal bone. Four patients had local deformity and external auditory meatus stenosis, two of which progressed to cholesteatoma. All patients showed some degree of hearing impairment. All had preserved otic capsule at the tomography. Two patients are currently undergoing clinical observation; two were submitted to tympanomastoidectomy due to secondary cholesteatoma; one was submitted to lesion resection, aiming to control the dysacusis progression. Conclusion: Five cases of fibrous dysplasia of the temporal bone were described, a rare disorder of which the otologist should be aware.

RESUMO Introdução: As queimaduras, um problema de saúde pública, são lesões que podem ocorrer na pele ou outros tecidos do corpo decorrentes de trauma de origem térmica, podendo ocasionar lesões leves, graves e até mesmo o óbito. Assim, são estudadas as características epidemiológicas dos pacientes atendidos na Unidade de Queimados do Hospital de Clínicas da Universidade Federal de Uberlândia. Métodos: Estudo transversal de dados registrados nos prontuários dos pacientes atendidos por queimadura na Unidade de Queimados de 2016 até 2019. Resultados: Um total de 252 prontuários foram revisados, sendo mais atingido o gênero masculino da faixa etária adulta. O principal agente causal foi o líquido inflamável (42,4%), com predomínio do álcool (66,35), acontecendo no domicílio (59,9%). O percentual médio da superfície corporal queimada foi de 17,7%, precisando de enxerto ou debridamento cirúrgico 25% dos pacientes. A média de internaçação foi 23,3 dias, com 8,7% necessitando de Unidade de Terapia Intensiva. A tentativa de autoextermínio foi de 5,5%, sendo a taxa geral de óbito de 3,5%. Conclusões: Pacientes por queimadura atendidos na Unidade de Queimados do Hospital de Clínicas da Universidade Federal de Uberlândia abrangem mais a população jovem e adulta, sendo o álcool a causa predominante, com média de óbitos similar a outras regiões. Este estudo ajudará a criar medidas no sentido de reduzir o número de casos e adequar o atendimento de forma quantitativa e qualitativa, contribuindo para a elaboração de protocolos de cuidados, a fim de assegurar a qualidade da assistência dos pacientes e da população em geral.

ABSTRACT Introduction: Burns, a public health problem, are injuries that can occur on the skin or other tissues of the body resulting from the trauma of thermal origin, which can cause mild, severe injuries and even death. Thus, the epidemiological characteristics of patients seen at the Burn unit of the Hospital de Clínicas of the Universidade Federal de Uberlândia are studied. Methods: Cross-sectional study of the data recorded in patients’ medical records treated for the burn at the Burn Units from 2016 to 2019. Results: 252 medical records were reviewed, with the male gender of the adult group being most affected. The main causal agent was the flammable liquid (42.4%) with a predominance of alcohol (66.35), occurring at home (59.9%). The average percentage of burned body surface was 17.7%, requiring a graft or surgical debridement in 25% of the patients. The average hospital stay was 23.3 days, requiring 8.7% of the Intensive Care Unit. The attempt at selfextermination was 5.5%, with a general death rate of 3.5%. Conclusions: Burn patients treated at the Burn Unit of the Hospital de Clínicas of the Universidade Federal de Uberlândia encompasses more of the young and adult population, with alcohol being the predominant cause, with an average death rate like other regions. This study will help create measures in search of reducing the number of cases and adapting the care quantitatively and qualitatively, contributing to the elaboration of care protocols to ensure the quality of the care of the patients and the population.

Abstract: En Pt

The objective of this work was to evaluate the chemical profile, total phenol content and the antioxidant, antiacetylcholinesterase and antifungal activities of ethanol extracts from leaves (EEF) and stem (EEC) of five species of Senna, as well as to evaluate the correlation between the content of total phenols with the DPPH free radical scavenging activity and with the inhibition of the acetylcholinesterase AChEI enzyme. The phytochemical test showed the presence of secondary metabolites in all extracts. The EEF and EEC of Senna trachypus, stood out for presenting the highest values of total phenols. S. trachypus EEF and EEC showed the best action on the acetylcholinesterase enzyme. All species showed antioxidant activity, especially the EEF from S. trachypus. A strong correlation was observed for the variables total phenols and antioxidant activity (r = -0.71), very strong for total phenols and anti-acetylcholinesterase (r = -0.84) and moderate activity for antioxidant and anti-acetylcholinesterase activity (r = 0.43). Only S. trachypus extracts showed activity against all dermatophytes, when compared to the other species. The species S. trachypus was considered the most promising plant for further studies, in order to find compounds with pharmacological actions.

O objetivo deste trabalho foi avaliar o perfil químico, teor de fenóis totais e as atividades antioxidante, antiacetilcolinesterásica e antifúngica dos extratos etanólicos das folhas (EEF) e do caule (EEC) de cinco espécies de Senna, bem como avaliar a correlação entre o conteúdo de fenóis totais com a atividade sequestradora do radical livre DPPH e com a inibição da enzima acetilcolinesterase AChEI. No teste fitoquímico, evidenciou-se a presença de metabólitos secundários em todos os extratos. Os EEF e EEC de Senna trachypus, destacaram-se por apresentar os maiores valores de fenóis totais. Os EEF e EEC de S. trachypus mostraram a melhor ação sobre a enzima acetilcolinesterase. Todas as espécies apresentaram atividade antioxidante, em especial o EEF de S. trachypus. Foi observado correlação forte para as variáveis fenóis totais e atividade antioxidante (rnbsp;=nbsp;-0,71), muito forte para fenóis totais e antiacetilcolinesterase (rnbsp;=nbsp;-0,84) e atividade moderada para atividade antioxidante e antiacetilcolinesterase (0,43). Apenas os extratos de S. trachypus apresentaram atividade contra todos os dermatófitos, quando comparado às demais espécies. A espécie S. trachypus foi considerada a planta mais promissora para estudos subsequentes, a fim de encontrar compostos com ações farmacológicas.
