Abordagem cirúrgica em fratura de sínfise e côndilo mandibular bilateral em paciente pediátrico: um relato de caso / Surgical approach for syphysis and bilateral mandibular condyle fracture in a pediatric patient: a case report

As indicações de tratamento das fraturas mandibulares em paciente pediátrico variam em conservador, fixação não rígida e interna rígida. Alterações no crescimento ósseo, disfunções na articulação temporomandibular e assimetrias faciais podem ser decorrentes ao insucesso do tratamento. O objetivo deste trabalho consiste em relatar abordagem cirúrgica em fratura de sínfise e côndilo mandibular bilateral em paciente pediátrico. Paciente gênero feminino, 09 anos de idade, foi encaminhada ao Hospital Geral do Estado - Bahia vítima de queda de nível, cursando com trauma em face. Apresentou queixa principal, referida pela progenitora, de dificuldades em fechar a boca. Ao exame físico, a paciente apresentou mobilidade atípica à manipulação da mandíbula, mordida aberta anterior, equimose sublingual, ausência das unidades dentárias 74 e 75, com abertura bucal regular e suturas em posição em região de mento. Ao exame de imagem de tomografia computadorizada da face, pôde-se notar sinais sugestivos de fratura em região de sínfise e côndilos mandibulares bilateral. Após diagnóstico das fraturas, a paciente foi submetida à cirurgia sob anestesia geral para redução e fixação das mesmas. Realizou-se acessos em ferimento na região mentual e retromandibular bilateral com posterior síntese das fraturas utilizando fixação interna rígida com placas do sistema 2.0mm, associada a odontossíntese na fratura de sínfise. Ao acompanhamento periódico, a eleição do tratamento cirúrgico para fraturas mandibulares em pacientes pediátricos, pode permitir segurança no crescimento ósseo mandibular e facial(AU)

The indications for treatment of mandibular fractures in pediatric patients vary from conservative, non-rigid fixation and rigid internal fixation. Changes in bone growth, temporomandibular joint disorders and facial asymmetries may be due to treatment failure. The objective of this work is to report a surgical approach to bilateral symphysis and mandibular condyle fractures in a pediatric patient. Female patient, 9 years old, was sent to the State General Hospital - Bahia, victim of a fall in level, suffering from trauma to the face. She presented a main complaint, mentioned by her mother, of difficulties in closing her mouth. On physical examination, the patient presented atypical mobility when manipulating the jaw, anterior open bite, sublingual ecchymosis, absence of dental units 74 and 75, with regular mouth opening and sutures in position in the chin region. When examining the computed tomography image of the face, signs suggestive of fracture in the region of the symphysis and bilateral mandibular condyles were noted. After diagnosis of the fractures, the patient underwent surgery under general anesthesia to reduce and fix them. Access was performed on a wound in the mental and bilateral retromandibular region with subsequent synthesis of the fractures using rigid internal fixation with 2.0mm system plates, associated with odontosynthesis in the symphysis fracture. With periodic monitoring, the choice of surgical treatment for mandibular fractures in pediatric patients can allow for safe mandibular and facial bone growth(AU)

Bacterial coinfections in COVID-19-hospitalized patients

SUMMARY OBJECTIVE: The aim of this study was to assess the rate of bacterial infections in COVID-19-hospitalized patients and to analyze the most prevalent germs, sources, risk factors, and its impact on in-hospital mortality. METHODS: This observational retrospective study was conducted on 672 patients hospitalized between April and August 2020 in Nossa Senhora da Conceição Hospital, a public hospital located in Porto Alegre, Brazil. The inclusion criterion was adult patients hospitalized with confirmed COVID-19. Data were collected through chart review. Risk factors for bacterial infection and mortality were analyzed using both univariate and multivariate robust Poisson regression models. RESULTS: Bacterial coinfection was observed in 22.2% of patients. Risk factors for bacterial infections were dementia (RR=2.06 (1.18-3.60); p=0.011), cerebrovascular disease (RR=1.75 (1.15-2.67); p=0.009), active cancer (RR=1.52 (1.082-2.15); p=0.01), need for noninvasive ventilation (RR=2.320 (1.740-3.094); p<0.01), invasive mechanical ventilation (RR=4.63 (2.24-9.56); p<0.01), and renal replacement therapy (RR=1.68 (1.26-2.25); p<0.01). In the adjusted model, bacterial infections were not associated with mortality (0.96 (0.75-1.24); p=0.79). The most common source of infection was due to respiratory, blood, and central venous catheters, with 69 (29.36%), 61 (25.96%), and 59 (25.11%) positive cultures, respectively. CONCLUSION: We observed a high rate of bacterial infections in COVID-19-hospitalized patients, most commonly of respiratory source. Neurologic and oncologic morbidities and need for ventilation and renal replacement therapy was associated with risk factors for bacterial infections. Nevertheless, an association between bacterial infections and hospital mortality was not established.

Internal carotid artery dissection associated with acute dengue virus infection: a case report / Dissecção da artéria carótida interna associada à infecção aguda pelo vírus da dengue: relato de caso

Cervical artery dissections (CAD) can occur spontaneously or as a direct result of significant trauma. Viral infections, such as SARS-CoV2, influenza, and Epstein Barr, are risk factors for spontaneous CAD. Dengue virus infections have dramatically increased in recent decades, and Brazil is one of the endemic areas. The dengue virus can cause headache and neurological complications such as encephalitis, myelitis, Guillain-Barré syndrome, and myositis. No report has yet been found in the literature of dissection of the internal carotid artery secondary to dengue infection. Our objective is to report the case of a patient with dissection of the internal carotid artery associated with acute dengue virus infection.

As dissecções da artéria cervical (DAC) podem ocorrer espontaneamente ou como resultado direto de trauma significativo. Infecções virais, como SARS-CoV2, influenza e Epstein Barr, são fatores de risco para DAC espontânea. As infecções pelo vírus da dengue aumentaram dramaticamente nas últimas décadas, e o Brasil é uma das áreas endêmicas. O vírus da dengue pode causar dor de cabeça e complicações neurológicas como encefalite, mielite, síndrome de Guillain-Barré e miosite. Ainda não foi encontrado na literatura nenhum relato de dissecção da artéria carótida interna secundária à infecção por dengue. Nosso objetivo é relatar o caso de um paciente com dissecção da artéria carótida interna associada à infecção aguda pelo vírus da dengue.

Resumo Objetivo: compreender os processos de vulnerabilização enfrentados pelos trabalhadores-migrantes canavieiros diante do avanço da mecanização. Métodos: abordagem qualitativa pautada na abordagem metodológica da Reprodução Social da Saúde proposta por Juan Samaja, nas dimensões biocumunal, tecnoeconômica e política. Foram realizadas 18 entrevistas semiestruturadas com trabalhadores-migrantes canavieiros no período de abril de 2020 a dezembro de 2021. Resultados: na dimensão tecnoeconômica verificou-se que na usina A o trabalhador se tornou polivalente, com a presença do trabalho em equipe e a introdução de tecnologias para aumentar o controle do trabalho. Na usina B, os trabalhadores encontram piores condições de trabalho devido à irrigação, à irregularidade dos terrenos, à presença de pedras e à exposição às queimadas. Na dimensão biocomunal, foram identificados potencialização dos acidentes, uso de agrotóxicos, distúrbios hidroeletrolíticos e problemas cardiovasculares. Na dimensão política, foi observada a precariedade da assistência à saúde do trabalhador canavieiro. Conclusão: a intensificação da mecanização na colheita de cana-de-açúcar não melhorou as condições de trabalho dos cortadores, ao contrário, provocou a perpetuação de velhos e a inserção de novos processos de vulnerabilização.

Clinical application and strategy of total-arterial coronary artery bypass grafting / 中国胸心血管外科临床杂志

@#Since the advent of coronary artery bypass grafting (CABG), the selection of bypass conduits has always been one of the most controversial topics in this field. Arterial conduits have received extensive attention due to their excellent biological features and high patency. In recent years, the application of arterial grafting and total arterial grafting in China keeps increasing in recent years, but there is still a gap compared to the Europe and America. Previous clinical studies have indicated the benefits of the total arterial grafting in terms of patency and long-term outcomes, but the advantage of multiple arterial grafting over other procedures is still in need to be confirmed with high-quality randomized controlled trials. This article reviews the clinical application and strategy of total-arterial CABG, aiming to provide objective reference for future clinical research and application.

Retrospective clinical study of hip replacement in the treatment of traumatic arthritis secondary to acetabular fracture / 中国骨伤

OBJECTIVE@#To investigate the clinical effect of total hip replacement (THA) in the treatment of traumatic arthritis secondary to acetabular fracture.@*METHODS@#From October 2019 to June 2022, 15 patients with secondary traumatic arthritis of acetabulum fracture were treated with THA. There were 8 males and 7 females, aged from 40 to 76 years old with an average of (59.20±9.46) years old. Prosthesis loosening, dislocation of hip joint, range of motion of hip joint, nerve injury and other conditions were recorded before and after surgery. Harris score, visual analogue scale (VAS) and imaging were used to evaluate hip joint function and surgical effect.@*RESULTS@#Follow-up time ranged 6 to 39 months with an average of (18.33±9.27) months. All the 15 patients successfully completed the operation, no nerve and blood vessel injury during the operation, postoperative wound healing was stageⅠ, no infection, one case of acetabular side prosthesis loosening at half a year after operation, and recovered well after revision surgery, one case of hip dislocation was cured after open reduction treatment, no adverse consequences. Harris score at the last postoperative follow-up was (88.60±4.01) points, compared with the preoperative (47.20±11.77) points, the difference was statistically significant (P<0.05), and VAS at the lateat postoperative follow-up was 1 (1) points, compared with the preoperative 8 (2) points, the difference was statistically significant (P<0.05). At the last follow-up, the pain symptoms were relieved or disappeared, and the joint function was satisfactory. The imaging data of the latest follow-up showed joint was well pseudoradiated, no abnormal ossification occurred, and the prosthesis was not loose.@*CONCLUSION@#THA is effective in the treatment of traumatic arthritis secondary to acetabular fracture and can effectively improve the quality of life of patients. Preoperative comprehensive evaluation and bone defect evaluation of patients, and intraoperative management of acetabulum, femur, internal fixation and bone defect are key factors for the success of surgery.

Retrospective analysis and comparison of total internal disability preservation technique and standardized reconstruction technique / 中国骨伤

OBJECTIVE@#To investigate the efficacy and clinical results of total internal protection technique in anterior cruciate ligament reconstruction.@*METHODS@#A total of 56 patients undergoing anterior cruciate ligament reconstruction treated from January 2018 to December 2019 were selected. According to the different surgical methods, they were divided into total internal reconstruction group and standard bone tunnel group. There were 21 patients in the total internal reconstruction group, including 15 males and 6 females, aged from 20 to 48 with an average of (35.6±6.7) years old, and 35 patients in the standard tibial tunnel group, including 26 males and 9 females, aged 22 to 51 years old with an average of (33.7±9.6) years old. Preoperative examination of Lachman test was positive, magnetic resonance indicated anterior cruciate ligament rupture. There were no significant differences between the two groups in age, sex, body mass index, time from injury to ACL reconstruction, combined meniscus injury and operation method, operation time, ligament diameter, ligament length and other general information. Postoperative evaluation included operation duration, length and diameter of transplanted tendon after braid. International Knee Documentation Committee (IKDC) score, Lysholm score, Tegner score and perioperative complications 2 years after surgery.@*RESULTS@#Both groups were followed up, ranging from 24 to 30 months with an average of (26.9±3.4) months. Postoperative incision healing was good, and no failure or joint infection occurred at the last follow-up. There was no statistically significant difference between the two groups in IKDC score, Lysholm score and Tegner score before, 1 year and 2 years after surgery. However, IKDC score, Lysholm score and Tegner score at 1 year and 2 years after surgery.@*CONCLUSION@#The same postoperative function and stability of knee joint can be obtained by both the residual whole technique and the standardized reconstruction technique. In the residual whole group, only the semitendinosus muscle is taken, and the femoral thin muscle is retained, with greater tibial bone mass preserved, which is safe and effective in clinical practice.

Research progress on biomechanics for internal fixation in tibial plateau fracture / 中国修复重建外科杂志

OBJECTIVE@#To review the biomechanical research progress of internal fixation of tibial plateau fracture in recent years and provide a reference for the selection of internal fixation in clinic.@*METHODS@#The literature related to the biomechanical research of internal fixation of tibial plateau fracture at home and abroad was extensively reviewed, and the biomechanical characteristics of the internal fixation mode and position as well as the biomechanical characteristics of different internal fixators, such as screws, plates, and intramedullary nails were summarized and analyzed.@*RESULTS@#Tibial plateau fracture is one of the common types of knee fractures. The conventional surgical treatment for tibial plateau fracture is open or closed reduction and internal fixation, which requires anatomical reduction and strong fixation. Anatomical reduction can restore the normal shape of the knee joint; strong fixation provides good biomechanical stability, so that the patient can have early functional exercise, restore knee mobility as early as possible, and avoid knee stiffness. Different internal fixators have their own biomechanical strengths and characteristics. The screw fixation has the advantage of being minimally invasive, but the fixation strength is limited, and it is mostly applied to Schatzker typeⅠfracture. For Schatzker Ⅰ-Ⅳ fracture, unilateral plate fixation can be used; for Schatzker Ⅴand Ⅵ fracture, bilateral plates fixation can be used to provide stronger fixation strength and avoid the stress concentration. The intramedullary nails fixation has the advantages of less trauma and less influence on the blood flow of the fracture end, but the fixation strength of the medial and lateral plateau is limited; so it is more suitable for tibial plateau fracture that involves only the metaphysis. Choosing the most appropriate internal fixation according to the patient's condition is still a major difficulty in the surgical treatment of tibial plateau fractures.@*CONCLUSION@#Each internal fixator has good fixation effect on tibial plateau fracture within the applicable range, and it is an important research direction to improve and innovate the existing internal fixator from various aspects, such as manufacturing process, material, and morphology.

O-arm navigation versus C-arm navigation for guiding percutaneous long sacroiliac screws placement in treatment of Denis type Ⅱ sacral fractures / 中国修复重建外科杂志

OBJECTIVE@#To compare the effectiveness of O-arm navigation and C-arm navigation for guiding percutaneous long sacroiliac screws in treatment of Denis type Ⅱ sacral fractures.@*METHODS@#A retrospective study was conducted on clinical data of the 46 patients with Denis type Ⅱ sacral fractures between April 2021 and October 2022. Among them, 19 patients underwent O-arm navigation assisted percutaneous long sacroiliac screw fixation (O-arm navigation group), and 27 patients underwent C-arm navigation assisted percutaneous long sacroiliac screw fixation (C-arm navigation group). There was no significant difference in gender, age, causes of injuries, Tile classification of pelvic fractures, combined injury, the interval from injury to operation between the two groups ( P>0.05). The intraoperative preparation time, the placement time of each screw, the fluoroscopy time of each screw during placement, screw position accuracy, the quality of fracture reduction, and fracture healing time were recorded and compared, postoperative complications were observed. Pelvic function was evaluated by Majeed score at last follow-up.@*RESULTS@#All operations were completed successfully, and all incisions healed by first intention. Compared to the C-arm navigation group, the O-arm navigation group had shorter intraoperative preparation time, placement time of each screw, and fluoroscopy time, with significant differences ( P<0.05). There was no significant difference in screw position accuracy and the quality of fracture reduction ( P>0.05). There was no nerve or vascular injury during screw placed in the two groups. All patients in both groups were followed up, with the follow-up time of 6-21 months (mean, 12.0 months). Imaging re-examination showed that both groups achieved bony healing, and there was no significant difference in fracture healing time between the two groups ( P>0.05). During follow-up, there was no postoperative complications, such as screw loosening and breaking or loss of fracture reduction. At last follow-up, there was no significant difference in pelvic function between the two groups ( P>0.05).@*CONCLUSION@#Compared with the C-arm navigation, the O-arm navigation assisted percutaneous long sacroiliac screws for the treatment of Denis typeⅡsacral fractures can significantly shorten the intraoperative preparation time, screw placement time, and fluoroscopy time, improve the accuracy of screw placement, and obtain clearer navigation images.

Endoscopic Orientation of Juxta-pituitary Carotid in Transsphenoidal Approaches: Critical Considerations for Clinical Applications

Abstract Introduction In sphenoid sinuses with ill-defined carotid bony landmarks, accidental injury of the internal carotid artery (ICA) remains one of the most challenging complications, which is particularly reported in the endoscopic endonasal transsphenoidal approaches (EETAs). Objectives To describe an anatomical model for the endoscopic orientation of the juxta-pituitary segment of the ICA in relation to the lateral opticocarotid recess (OCR) as a nearby bony landmark. Methods Dissection was performed progressively, simulating the EETA, in twenty fresh adult cadavers. After reducing the posterior and lateral walls of the sphenoid sinuses, various measurements were taken from both lateral OCRs to "contact points" on the juxta-pituitary segment of the ICA and lateral margins of the pituitary gland. Results The current results have enabled us to divide the region between the lateral OCRs into 3 compartments: 2 lateral parasellar compartments contain juxta-pituitary segments of the ICA with a mean width of 8 mm and a narrow range from 7 mm to 10 mm; and a central intercarotid sellar compartment represents the safe region for bone drilling, showing widely variable widths ranging from 9 mm to 20 mm. In all specimens, the variation in the width of the intercarotid compartment correlated with the distance between both lateral OCRs. Conclusion The present study improves surgeon awareness of the variations in the course of the ICA through the EETA along sphenoid sinuses with ill-defined bony landmarks. An appreciation of the measurements taken in the present study can help in operative training, and can also provide a base for future studies to confirm ICA courses associated with a higher risk of injury.

Test de Atención Infantil: análisis de las características psicométricas y valores de referencia preliminares / Test of Child Attention: Analysis of the Psychometric Characteristics and Preliminary Reference Values / Teste de Atenção Infantil: análise de características psicométricas e valores de referência preliminares

La atención es definida como un constructo multidimensional, encargado de regular sobre qué estímulos se dirigirán los recursos perceptivos, filtrando información irrelevante con el fin de favorecer la retención de información durante un período antes de actuar sobre ella. La evaluación computarizada de la atención ha ido cobrando relevancia tanto en la investigación como en las prácticas del quehacer profesional. Los objetivos de este estudio fueron: 1) analizar la consistencia interna y la validez concurrente del Test de Atención Infantil 6.0 (tai), versión computarizada; y 2) obtener los valores de referencia preliminares para cada subtest del tai. Los estudios de confiabilidad y validez del tai corresponden a una muestra de 122 escolares de Mendoza (Argentina). Al analizar la consistencia interna se obtuvieron valores satisfactorios para cada uno de los subtests (Test 1, kr 20 = 0.78; Test 2, kr 20 =0.74; Test 3, kr20 = 0.73). Se obtuvieron valores satisfactorios al explorar la estabilidad del instrumento. Al analizar la validez concurrente, los resultados indicaron correlaciones positivas moderadas y significativas (p <0.01) entre el test Caras-R y los subtests 1 y 2 del tai, utiliza-do para evaluar desempeño atencional. Se observaron asociaciones positivas significativas (p <0.01) entre el subtest 3 del tai y el Test de Bloques de Corsi, usado para evaluar memoria de trabajo visoespacial. Estos resultados señalan que el tai, instrumento desarrolla-do para evaluar la atención y memoria de trabajo visuoespacial en escolares, presenta indicadores adecuados de validez y confiabilidad. Se discuten los hallazgos, limitaciones y futuras líneas de investigación.

Attention has been defined as a multidimensional construct, dealing with regulation of which stimuli the perceptual resources are directed to, filtering irrelevant information out to favor the retention of relevant information for a period of time, before acting on it. The computerized evaluation of attention has been gaining relevance both in research and in professional practice. The objectives are: 1) to analyze internal consistency and concurrent validity of the Child Attention Test 6.0 (tai), computerized version 6.0; and, 2) to obtain the preliminary reference values for each of the tai subtests done. The data for the validity and reliability studies of the tai corresponds to a sample of 122 schoolchildren in Mendoza (Argentina). When analyzing the internal consistency, satisfactory values were obtained for each subtest (Test 1, kr 20 = 0.78; Test 2, kr 20 = 0.74; and Test 3, kr 20 = 0.73). Satisfactory values were obtained when exploring the stability of the instrument. For concurrent validity, the results indicate significant moderate positive correlations (p <0.01) between the scores obtained in the Caras-R test and subtests 1 and 2 of the tai, used to evaluate attentional performance. Significant positive associa-tions (p <0.01) were observed between tai subtest 3 and the Corsi Block Test, used to assess visuospatial working memory. These results indicate that the tai, an instrument developed in order to evaluate attention and visuospatial working memory of school children, presents adequate indicators of validity and reliability. The findings, limitations, and future lines of research are discussed

How can internal marketing practices help achieve organizational success? / ¿Cómo las prácticas de marketing interno pueden ayudar a lograr el éxito organizacional? / Como as práticas de marketing interno podem ajudar a alcançar o sucesso organizacional?

Abstract Internal marketing is a concept still little recognized and disseminated, with most of the research on this area of marketing focusing on the service sector and well-consolidated and industrialized markets. This article sheds light on the importance of internal marketing practices by identifying their impact on workers' proactive behavior and life satisfaction while observing the effects of affective commitment and job satisfaction. The study collected 428 valid questionnaires from Portuguese workers (218 in the private sector and 210 in the public sector) and applied structural equation modeling to test the hypotheses. The results showed how adopting an internal marketing perspective can contribute to successful organizational and human resource management. It was observed that internal marketing practices lead to affective commitment and job satisfaction in both the private and public sectors, although more pronounced in the private sector. Also, the findings pointed out that the workers' affective commitment leads to adopting proactive behavior and life satisfaction only in the public sector and that job satisfaction leads to proactive behavior and life satisfaction for workers of both the private and public sector. This study contributes to increasing understanding of internal marketing, its applicability, and its importance for workers and organizations. Additionally, comparing the private and public sectors helps understand and show how this practice matches the workers' expectations.

Resumen Este artículo tiene como objetivo arrojar luz sobre la importancia de las prácticas de marketing interno, identificando su impacto en el comportamiento proactivo y en la satisfacción con la vida de los trabajadores, a través de los efectos del compromiso afectivo y la satisfacción laboral. El marketing interno sigue siendo un concepto poco reconocido y difundido. Esta investigación compara estos efectos entre los trabajadores del sector público y privado para reforzar la importancia de dicho concepto. En total, se recogieron 428 cuestionarios válidos de trabajadores portugueses (218 del sector privado y 210 del sector público). Se utilizó el modelo de ecuaciones estructurales para testar las hipótesis de estudio. Esta investigación muestra cómo la adopción de una perspectiva de marketing interno puede contribuir a una gestión organizacional y gestión de personas exitosa. Los resultados mostraron que las prácticas de marketing interno generan compromiso afectivo y satisfacción laboral, tanto en el sector privado como en el público, aunque de forma más acentuada en el sector privado. También se constató que el compromiso afectivo conduce a la adopción de conductas proactivas y a la satisfacción con la vida de los trabajadores del sector público únicamente, y que la satisfacción laboral conduce a la adopción de esta conducta y a la satisfacción con la vida para ambos, sector público y privado. Este trabajo contribuye a una mejor comprensión del concepto de marketing interno y su aplicabilidad e importancia para los trabajadores y las organizaciones. Además, al comparar los sectores público y privado, ayuda a comprender y mostrar cómo esta práctica coincide con las expectativas de los trabajadores de estos dos sectores.

Resumo Este estudo pretende evidenciar a importância das práticas de marketing interno, identificando o seu impacto no comportamento proativo e na satisfação com a vida dos trabalhadores, através dos efeitos do compromisso afetivo e da satisfação no trabalho. O marketing interno continua a ser um conceito com pouco reconhecimento e divulgação, uma vez que a maioria das pesquisas relacionadas com esse campo de marketing é direcionada para o setor de serviços e concentra-se predominantemente em mercados bem estabelecidos e industrializados. Esta pesquisa compara esses efeitos entre trabalhadores do setor privado e público para reforçar a importância deste conceito, sendo que, no total, foram recolhidos 428 questionários válidos junto de trabalhadores portugueses (218 no setor privado e 210 no setor público). O modelo de equações estruturais foi utilizado para testar as hipóteses de investigação. Esta pesquisa mostra como a adoção do marketing interno pode contribuir para o sucesso da gestão organizacional e da gestão de pessoas. Os resultados mostraram que as práticas de marketing interno levam ao comprometimento afetivo e à satisfação no trabalho, tanto no setor privado como no público, embora mais pronunciadas no setor privado. Constatou-se também que o comprometimento afetivo leva à adoção de comportamentos proativos e leva à satisfação com a vida dos trabalhadores, mas apenas do setor público, e que a satisfação no trabalho leva à adoção desse comportamento e à satisfação com a vida para ambos, setor privado e público. Este trabalho contribui para uma melhor compreensão do conceito de marketing interno, da sua aplicabilidade e importância, quer para os trabalhadores, como para as organizações. Além disso, ao comparar os setores privado e público, ajuda a entender e mostrar como essa prática atende às expectativas dos trabalhadores desses dois setores.

Internal occupational dosimetry for the occupational worker exposed to [18F] FDG from the Cyclotron-PET/CT Laboratory of the Universidad de Costa Rica / Dosimetría ocupacional interna para el personal trabajador expuesto a [18F] FDG del ciclotrón-PET/CT en el Laboratorio de la Universidad de Costa Rica

ABSTRACT: The aim of this work is to provide a methodology for evaluating the committed effective dose E(50) due to the incorporation of [18F] FDG in the occupationally exposed worker (OEW) of the Cyclotron-PET/CT Laboratory of the Centro de Investigación en Ciencias Atómicas, Nucleares y Moleculares (CICANUM) at Universidad de Costa Rica using in vivo measurements. The measurement system was calibrated to perform in vivo measurements and defined as the corresponding bioassay function for the radiopharmaceutical used. The conversion factor was assessed with a known activity of 18F in the geometry and measurement time established. Among the most relevant results, the measurement parameters and the calibration procedure were defined. A value of 1.73 x 103 Bq/cps for in vivo brain measurements was obtained as a conversion factor. This study provides a methodology, to evaluate the committed effective dose due to the incorporation of 18F-FDG in a radionuclide production and diagnostic center

Introducción. El objetivo del estudio fue describir las características sociodemográficas, tratamiento y complicaciones pre y posquirúrgicas de las fracturas supracondíleas del húmero distal en niños que requirieron manejo quirúrgico en un hospital de Santander, Colombia. Metodología. Se trata de un estudio observacional, descriptivo, de corte transversal con 58 pacientes que cumplieron los siguientes criterios de inclusión: edad entre 3 a 14 años, fracturas supracondíleas de manejo quirúrgico; como criterios de exclusión se tomó: antecedente de enfermedad ósea o neurológica previa y fracturas de más de 7 días de evolución. Para las variables continuas se usó medidas de tendencia central y dispersión, las categóricas en porcentajes y frecuencias absolutas. Resultados. La edad media de presentación fue de 6.2 años, el principal mecanismo de trauma fue caídas de altura con un 96.5%. El 65.5% provenía de zonas urbanas. El 13.8% se asoció con fracturas de antebrazo, y el 3.4% de epitróclea. La fijación se realizó en un 75% con técnica cruzada y un 17.2% se asoció con lesión iatrogénica del nervio ulnar. Discusión. En el estudio no se informaron lesiones vasculares; sin embargo, se documentó una alta prevalencia de lesión neurológica con la fijación medial, similar a lo descrito en la literatura (1.4%-17.7%); algunos autores describen técnicas que disminuyen estas lesiones hasta en un 0%. Conclusión. Las características sociodemográficas de nuestra población coinciden con la estadística publicada mundialmente; la principal complicación fue la lesión iatrogénica nervio ulnar, que se puede disminuir con un uso racional del pin medial y con el empleo de técnicas que busquen rechazar directamente el nervio.

Introduction. The objective of this study was to describe sociodemographic characteristic, treatment, and pre- and post-surgical complications of supracondylar fractures of the distal humerus in children who required surgical management at a hospital in Santander, Colombia. Methodology. This was an observational, descriptive, and cross-sectional study involving 58 patients who met inclusion criteria: age between 3 and 14 years old, supracondylar fractures with surgical management; exclusion criteria include previous bone or neurological illness and fractures with more than 7 days of evolution. Central tendency and dispersion measures were used for continuous variables, and categorical variables in percentages and absolute frequencies. Results. The average age at presentation was 6.2 years old, the main mechanism of trauma was fall from height (96.5%). 65.5% came from urban zones. The 13.8% were associated with forearm fractures, and 3.4% with epitrochlear fractures. Pinning was performed at 75% with crossed technique and 17.2% were associated with iatrogenic ulnar nerve injury. Discussion. Study didn't inform vascular injuries. However, a high prevalence of neurological injury with medial pinning was documented, similar to that describe in the literature (1.4%-17.7%); some author described techniques that reduce these lesions by 0%. Conclusion. The sociodemographic characteristics of our population match with worldwide published statistics; the main complication was iatrogenic ulnar nerve injury, which can be reduced with the rational use of medial pin and with the application of techniques that seek to directly spare the nerve.

Relación entre modelos operantes internos y nivel educacional materno, con la teoría de la mente en niños chilenos de 3 y 4 años: rol mediador del lenguaje mentalizante materno / Relationship between Internal Working Models and Maternal Educational Level, with the Theory of Mind of Chilean Children Aged 3 and 4: Mediating Role of Maternal Mentalizing Language

Resumen La teoría de la mente (ToM) es la capacidad de reconocer los propios estados mentales y predecir los de otros, habilidad fundamental en el desarrollo socioemocional/cognitivo en preescolares. El presente estudio buscó describir la ToM de niños chilenos de 3 y 4 años, analizar las diferencias en su desarrollo según la edad y el rol mediador del lenguaje mentalizante (LM) materno, considerando el sexo de los niños, los modelos operantes internos (MOI) y el nivel educacional materno. La muestra fueron 110 niños con sus madres. Se aplicó un cuestionario sociodemográfico, pruebas para evaluar la ToM, el LM y los MOI de las madres. Un 50.9% de los niños se ubicó en el quintil 1 de la ToM y ninguno logró llegar al quinto. Las habilidades de la ToM con un mayor nivel de logro diferenciaron entre pretender y realidad (60.0%) y la de diferenciar la perspectiva visual propia y de otro (50.9%). Un 59.1 % de los niños no logró inferir deseos a través de la mirada, un 83.6% no logró la habilidad de acceso al conocimiento, y un 100% no logró la falsa creencia. Los resultados muestran diferencias significativas entre niños de distintos rangos etarios en el desarrollo de la ToM, sugiriendo una creciente dificultad de adquisición de sus habilidades. Además, un mayor LM de las madres se relacionó con mayor desarrollo de la ToM en los niños, con un rol mediador en la influencia de los MOI y nivel educacional materno sobre la ToM.

Abstract The theory of mind (ToM) is the ability to recognize one's own mental states and infer them in others, fundamental in socio-emotional/cognitive development in preschoolers. This study sought to describe the ToM of 3- and 4-year-old Chilean children, to analyze the differences in their development according to age, and the mediating role of maternal mentalizing language (ML) considering the sex of the children, the internal working models (IWM) and maternal educational level. The sample considered 110 children with their mothers. A sociodemographic questionnaire, tests to evaluate the ToM, the ML and the IWM of the mothers were applied. 50.9% of the children were in quintile 1 of the ToM and none managed to reach the fifth. The ToM skills with a higher level of achievement were differentiating between pretending and reality (60.0%) and differentiating one's own visual perspective and another's (50.9%). 59.1 % of the children did not manage to infer wishes through the gaze, 83.6% did not achieve the ability to access knowledge, and 100% did not achieve the false belief. The results show significant differences between children of different age ranges in the development of ToM, suggesting a growing difficulty in acquiring their skills. In addition, a higher ML in mothers was related to a greater development of ToM in children, with a mediating role in the influence of IWM and maternal educational level on ToM.
