Significance of radiologic extranodal extension in locoregionally advanced nasopharyngeal carcinoma with lymph node metastasis: a comprehensive nomogram

Abstract Objective We aimed to assess the significance of rENE and creat a predictive tool (nomogram) for estimating Overall Survival (OS) in locoregionally advanced Nasopharyngeal Carcinoma (NPC) patients with Lymph Node Metastasis (LNM) based on their clinical characteristics and Radiologic Extranodal Extension (rENE). Methods Five hundred and sixty-nine NPC patients with LNM were randomly divided into training and validation groups. Significant factors were identified using univariate and multivariate analyses in the training cohort. Then, the nomogram based on the screening results was established to predict the Overall Survival (OS). Calibration curves and the Concordance index (C-index) gauged predictive accuracy and discrimination. Receiver Operating Characteristic (ROC) analysis assessed risk stratification, and clinical utility was measured using Decision Curve Analysis (DCA). The nomogram's performance was validated for discrimination and calibration in an independent validation cohort. Results A total of 360 (63.2%) patients were present with radiologic extranodal extension at initial diagnosis. Patients with rENE had significantly lower OS than other patients. Multivariate analysis identified the five factors, including rENE, for the nomogram model. The C-index was 0.75 (0.71-0.78) in the training cohort and 0.76 (0.69-0.83) in the validation cohort. Notably, the nomogram outperformed the 8th TNM staging system, as evident from the higher AUC values (0.77 vs. 0.60 for 2 year and 0.75 vs. 0.65 for 3 year) and well-calibrated calibration curves. Decision curve analysis indicated improved Net Benefit (NB) with the nomogram for predicting OS. The log-rank test confirmed significant survival distinctions between risk groups in both training and validation cohorts. Conclusions We demonstrated the prognostic value of rENE in nasopharyngeal carcinoma and developed a nomogram based on rENE and other factors to provide individual prediction of OS for locoregionally advanced nasopharyngeal carcinoma with lymph node metastasis. Level of evidence: III.

Invasiveness assessment by CT quantitative and qualitative features of lung cancers manifesting ground-glass nodules in 555 patients: A retrospective cohort study / 中国胸心血管外科临床杂志

@#Objective     To explore the correlation between the quantitative and qualitative features of CT images and the invasiveness of pulmonary ground-glass nodules, providing reference value for preoperative planning of patients with ground-glass nodules. Methods    The patients with ground-glass nodules who underwent surgical treatment and were diagnosed with pulmonary adenocarcinoma from September 2020 to July 2022 at the Third Affiliated Hospital of Kunming Medical University were collected. Based on the pathological diagnosis results, they were divided into two groups: a non-invasive adenocarcinoma group with in situ and minimally invasive adenocarcinoma, and an invasive adenocarcinoma group. Imaging features were collected, and a univariate logistic regression analysis was conducted on the clinical and imaging data of the patients. Variables with statistical difference were selected for multivariate logistic regression analysis to establish a predictive model of invasive adenocarcinoma based on independent risk factors. Finally, the sensitivity and specificity were calculated based on the Youden index. Results     A total of 555 patients were collected. The were 310 patients in the non-invasive adenocarcinoma group, including 235 females and 75 males, with a meadian age of 49 (43, 58) years, and 245 patients in the invasive adenocarcinoma group, including 163 females and 82 males, with a meadian age of 53 (46, 61) years. The binary logistic regression analysis showed that the maximum diameter (OR=4.707, 95%CI 2.060 to 10.758), consolidation/tumor ratio (CTR, OR=1.027, 95%CI 1.011 to 1.043), maximum CT value (OR=1.025, 95%CI 1.004 to 1.047), mean CT value (OR=1.035, 95%CI 1.008 to 1.063), spiculation sign (OR=2.055, 95%CI 1.148 to 3.679), and vascular convergence sign (OR=2.508, 95%CI 1.345 to 4.676) were independent risk factors for the occurrence of invasive adenocarcinoma (P<0.05). Based on the independent predictive factors, a predictive model of invasive adenocarcinoma was constructed. The formula for the model prediction was: Logit(P)=–1.293+1.549×maximum diameter of lesion+0.026×CTR+0.025×maximum CT value+0.034×mean CT value+0.72×spiculation sign+0.919×vascular convergence sign. The area under the receiver operating characteristic curve of the model was 0.910 (95%CI 0.885 to 0.934), indicating that the model had good discrimination ability. The calibration curve showed that the predictive model had good calibration, and the decision analysis curve showed that the model had good clinical utility. Conclusion     The predictive model combining quantitative and qualitative features of CT has a good predictive ability for the invasiveness of ground-glass nodules. Its predictive performance is higher than any single indicator.

Clinical characteristics and prognosis of children with spinal cord injury without radiologic abnormality caused by non-severe violence / 中国小儿急救医学

Objective:To investigate the causes, diagnosis, treatment and prognosis of children with spinal cord injury without radiologic abnormality caused by non-severe violence, and to raise the awareness of spinal cord injury in children.Methods:Retrospective analysis was performed on the age of onset, injury mechanism, main clinical symptoms and occurrence time, treatment process and recovery of children with spinal cord injury without radiologic abnormality caused by non-severe violence. The children were admitted to our hospital from August 2015 to September 2020. Abnormal findings in spinal cord MRI in acute stage were analyzed, and long-term prognosis was followed up by telephone. The degree of spinal cord injury was determined according to the criteria established by the American Spinal Cord Injury Association.Results:Of six patients, three boys and three girls, aged from 16 months to 8 years old.Injury mechanism: fall on the bed, a sudden fall in standing position, fall while jumping in sports.All of the symptoms appeared immediately after trauma, such as limb weakness, pain, unable to walk, urination disorders.Treatment process: spinal immobilization, methylprednisolone pulse therapy[20 mg/(kg·d)], alleviat edema and protect the nerve system, necessary symptomatic treatment including urethral catheterization, the use of antibiotics, timely rehabilitation treatment.No fracture or dislocation was found in all six patients by spinal cord radiometric examination, and MRI of spinal cord indicated abnormal signals of thoracic cord or below. The recovery sequence of spinal cord function: urination function recovery, pain from lower limbs relief, lower limbs weakness improvement.By the time of follow-up by telephone, the course of disease was 1 to 5 years. Urine fecal incontinence was found in one patient, and his muscle strength of both lower extremities belong to grade Ⅰ, atrophic changes were found in spinal cord MRI.The remaining five patients were able to walk independently, complained of leg pain during long distance walking, mild varus or valgus, and no obvious abnormality in spinal cord MRI.Conclusion:In daily activities, except bend down in dancing, falling on the sacral tail is easy to cause spinal cord injury without fracture and dislocation in children. The damaged spinal cord function often cannot recover thoroughly, and even cannot recover. It is advisable to identify early, formulate comprehensive treatment measures in time, strive to improve the prognosis.

Clinical and radiologic outcomes after tendon insertion medialized repair of large-to-massive rotator cuff tears / 中国修复重建外科杂志

OBJECTIVE@#To evaluate the effectiveness of tendon insertion medialized repair in treatment of large-to-massive rotator cuff tears (L/MRCT).@*METHODS@#The clinical and imaging data of 46 L/MRCT patients who underwent arthroscopic insertion medialized repair between October 2015 and June 2019 were retrospectively analyzed. There were 26 males and 20 females with an average age of 57.7 years (range, 40-75 years). There were 20 cases of large rotator cuff tears and 26 cases of massive rotator cuff tears. Preoperative imaging evaluation included fatty infiltration (Goutallier grade), tendon retraction (modified Patte grade), supraspinatus tangent sign, acromiohumeral distance (AHD), and postoperative medializaiton length and tendon integrity. The clinical outcome was evaluated by visual analogue scale (VAS) score, American Society for Shoulder and Elbow Surgery (ASES) score, shoulder range of motion (including anteflexion and elevation, lateral external, and internal rotation) and anteflexion and elevation muscle strength before and after operation. The patients were divided into two groups (the intact tendon group and the re-teared group) according to the integrity of the tendon after operation. According to the medializaiton length, the patients were divided into group A (medialization length ≤10 mm) and group B (medialization length >10 mm). The clinical function and imaging indexes of the patients were compared.@*RESULTS@#All patients were followed up 24-56 months, with an average of 31.8 months. At 1 year after operation, MRI showed that the medializaiton length of supraspinatus tendon was 5-15 mm, with an average of 10.26 mm, 33 cases in group A and 13 cases in group B. Eleven cases (23.91%) had re-teared, including 5 cases (45.45%) of Sugaya type Ⅳ and 6 cases (54.55%) of Sugaya type Ⅴ. At last follow-up, the VAS score, ASES score, shoulder anteflexion and elevation range of motion, lateral external rotation range of motion, and anteflexion and elevation muscle strength significantly improved when compared with those before operation ( P<0.05); there was no significant difference in internal rotation range of motion between pre- and post-operation ( P>0.05). The Goutallier grade and modified Patte grade of supraspinatus muscle in the re-teared group were significantly higher than those in the intact tendon group, and the AHD was significantly lower than that in the intact tendon group ( P<0.05). There was no significant difference in other baseline data between the two groups ( P>0.05). Except that the ASES score of the intact tendon group was significantly higher than that of the re-teared group ( P<0.05), there was no significant difference in the other postoperative clinical functional indicators between the two groups ( P>0.05). There was no significant difference in the incidence of re-tear, VAS score, ASES score, range of motion of shoulder joint, and anteflexion and elevation muscle strength between group A and group B ( P>0.05).@*CONCLUSION@#Tendon insertion medialized repair may be useful in cases with L/MRCT, and shows good postoperative shoulder function. Neither tendon integrity nor medialization length shows apparent correlations with postoperative shoulder function.

Avances y desafíos de la protección radiológica en cardiología intervencionista pediátrica para Chile entre los años 2013-2021 / Updating radiological protection for interventional procedures in pediatric cardiology in Chile

RESUMEN: En el año 2013, se publicó un artículo acerca de lo realizado en Chile en temas de protección radiológica en cardiología intervencionista (CI) pediátrica. A continuación se muestra el trabajo de continuidad realizado en los últimos 8 años, destacando los principales resultados alcanzados y proponiendo mejoras en la seguridad y protección radiológica en esta práctica clínica. Desde el año 2013 se han seguido evaluando en términos de dosis de radiación y calidad de imagen, los sistemas de rayos X utilizados en Chile para procedimientos de CI pediátricos y, en particular, los equipos de los servicios de los Hospitales Luis Calvo Mackenna y Roberto del Rio. Se han medido las tasas de dosis de radiación dispersa a la posición habitual de los ojos y tobillos de los cardiólogos que operan los equipos de rayos X. También contamos con un conjunto de "Niveles de Referencia para Diagnóstico" clasificados por rangos de edad y peso, junto con la estimación de valores de dosis por órgano y dosis efectiva para los pacientes. Podemos afirmar que, actualmente, contamos con una metodología consolidada para caracterizar, en términos de dosis y calidad de imagen, los sistemas de rayos X. Sin embargo, sigue pendiente actualizar la normativa nacional que regula el uso seguro de las radiaciones ionizantes en medicina, como también aspectos de formación en protección radiológica para el personal médico implicado.

ABSRSCT: An article on the status of radiological protection during procedures of interventional cardiology in pediatric patients in Chile was published in 2013. The present article relates the continuing efforts to improve radiological protection highlighting their results and proposing additional measures to improve radiological protection during the procedure. Since 2013 we have continued the evaluation of radiation doses, image quality, and X Ray systems used in Chile. We have measured diffused radiation dose at operator´s eye and ankle levels to elaborate a "Reference guide" according to patient´s age and weight. However, we still lack a national regulatory norm for the X Ray systems to be used and for the appropriate training of those involved in procedures of interventional cardiology in pediatric patients.

Monitoring non-small cell lung cancer progression and treatment response through hyaluronic acid in sputum

We evaluated whether hyaluronan (HA) levels in the sputum could be used as a noninvasive tool to predict progressive disease and treatment response, as detected in a computed tomography scan in non-small cell lung cancer (NSCLC) patients. Sputum samples were collected from 84 patients with histological confirmation of NSCLC, 33 of which were in early-stage and 51 in advanced-stage disease. Patients received systemic chemotherapy (CT) after surgery (n=36), combined CT and immunotherapy (IO) (n=15), or targeted therapy for driver mutation and disease relapse (N=4). The primary end-point was to compare sputum HA levels in two different concentrations of hypertonic saline solution with overall survival (OS) and the secondary and exploratory end-points were radiologic responses to treatment and patient outcome. Higher concentrations of HA in the sputum were significantly associated to factors related to tumor stage, phenotype, response to treatment, and outcome. In the early stage, patients with lower sputum HA levels before treatment achieved a complete tumor response after systemic CT with better progression-free survival (PFS) than those with high HA levels. We also examined the importance of the sputum HA concentration and tumor response in the 51 patients who developed metastatic disease and received CT+IO. Patients with low levels of sputum HA showed a complete tumor response in the computed tomography scan and stable disease after CT+IO treatment, as well as a better PFS than those receiving CT alone. HA levels in sputum of NSCLC patients may serve as a candidate biomarker to detect progressive disease and monitor treatment response in computed tomography scans.

Application of imaging techniques in diagnosis and severity assessment of dermatomyositis / 中华皮肤科杂志

Dermatomyositis is an autoimmune disease involving the skin and muscles. At the onset of dermatomyositis, it is difficult to make an early diagnosis due to atypical clinical manifestations and lack of serological markers. Skin and muscle lesions are associated with disease activity and prognosis in patients with dermatomyositis or clinical amyopathic dermatomyositis. Computed tomography, magnetic resonance imaging, ultrasonography, dermoscopy and other imaging techniques may be used to assess skin and muscle involvements, which can not only improve the accuracy of early diagnosis of dermatomyositis, but also provide important reference for the assessment of disease activity and prognosis.

Peripheral venous puncture and contrast in radiological exams: social representations anchored in neuman's stressors / Punción venosa periférica y contraste en exámenes radiológicos: representaciones sociales ancladas en los estresores de neuman / Punção venosa periférica e contraste nos exames radiológicos: representações sociais ancoradas nos estressores de neuman

ABSTRACT Objective: to discuss the social representations about peripheral venipuncture and the use of contrast media of people submitted to radiological examinations, referring to stressor concept. Method: this is qualitative research, outlined in the procedural approach of the Social Representation Theory, carried out with 57 users undergoing computed tomography and magnetic resonance imaging at a university hospital in Juiz de Fora, Minas Gerais, Brazil. In-depth individual interviews triggered by guiding questions were conducted in January 2019. The contents of the interviews were fully transcribed and content analysis was carried out in three stages (pre-analysis, material exploration and treatment/interpretation of results). We established thematic analysis based on the dimensions and representational origins, which made it possible to discuss the findings anchored in the concepts of stressors, allowing the identification of three categories based on intrapersonal, interpersonal and transpersonal stressors. Results: puncture and examination were represented by individual, group, professional and therapeutic environment experiences, classified into the following categories: itinerary and conceptions on puncture and contrasted examinations based on intrapersonal stressors; shared relationships on puncture and examination, based on interpersonal stressors; and experiences in the therapeutic environment of a diagnostic imaging service, based on transpersonal stressors. Conclusion: the social representations were signified by examination, results and impacts on life, portraying stressors based on images/feelings of doubt and positive behaviors rationally justified, which explain human responses to reified content, enabling the restructuring of health care and nursing.

RESUMEN Objetivo: discutir las representaciones sociales sobre la venopunción periférica y el uso de medios de contraste en personas sometidas a exámenes radiológicos, refiriéndose al concepto de estresores.

Conclusão: as representações sociais foram significadas por exame, resultado e impactos na vida, retratando estressores alicerçados em imagens/sentimentos de dúvida e comportamentos positivos justificados racionalmente, que explicitam respostas humanas a conteúdos reificados, possibilitando a reestruturação do cuidado em saúde e em enfermagem.

Anatomia radiológica vascular e desenvolvimento de plataformas de ensino interativo / Vascular radiological anatomy and the development of interactive teaching platforms

Anatomia e Radiologia são disciplinas amplamente presentes nas grades curriculares de cursos da área da saúde. A interseção entre a Anatomia Radiológica e as tecnologias recentes, como plataformas de ensino interativo, caracteriza-se como uma tendência a ser seguida na esfera educacional, sendo as implicações desse processo ainda não muito debatidas. O Departamento de Anatomia da Universidade Federal de Juiz de Fora iniciou o desenvolvimento de um atlas de anatomia vascular radiológica, o qual apresenta versões impressa e interativa. Possui imagens de angiotomografias computadorizadas feitas em aparelhos multislice de 16 a 128 canais, sendo as imagens de arquivo pessoal dos organizadores. O atlas promove a identificação das estruturas vasculares em questão e propicia a integração do conhecimento adquirido em salas de aula com a visualização de exames de imagem complementares rotineiros. A indiscutível presença de exames de imagem adicionais na rotina dos profissionais da saúde atuais faz com que seja válida a estratégia de integração entre o método tradicional de ensino e as práticas ativas de aprendizagem, as quais vêm ganhando destaque recentemente, devido a sua efetividade na fixação de conhecimentos.

Anatomy and Radiology are subjects widely present in health courses at universities. The intersection between Radiological Anatomy and recent technologies, such as interactive teaching platforms, is characterized as a tendency to be followed in the educational sphere, and the implications of this process are not much debated. The Department of Anatomy of Juiz de Fora Federal University has begun the development of an atlas of radiological vascular anatomy, which features printed and interactived versions. It presents computed tomography images taken on multislice devices from 16 to 128 channels, and the images are from the personal authors' archives. The Radiologic Vascular Atlas provides the identification of vascular structures in study and makes easier the integration of knowledge acquired in classrooms with the visualization of routine complementary imaging exams. The indisputable presence of complementary imaging examinations in the routine of current health professionals makes valid the strategy of integration between the traditional teaching method and active learning practices, which have recently gained prominence, due to its effectiveness in setting knowledge.

Acreditação dos serviços de radiologia e diagnóstico por imagem: princípio gestão da qualidade / Accreditation of radiology and diagnostic imaging services: quality management principle

A gestão da qualidade tem evoluído ao longo do tempo e é entendida neste estudo como a essência nos serviços de imagem, preconizando, por meio dos requisitos contidos programa de acreditação em diagnóstico por imagem, práticas que permitam coordenar e controlar o serviço no sentido de possibilitar a melhoria contínua na estrutura, processos e resultados visando o fortalecimento das ações que envolvem o serviço como um todo, os profissionais e os pacientes. Para isso é fundamental a gestão dos documentos, identificação, tratamento e monitoramento dos riscos, das não conformidades, dos eventos adversos, concorrendo para sua mitigação e prevenção de ocorrência. A avaliação periódica da qualidade como um sistema, pela correlação existente entre os requisitos prescritos, resultados das auditorias internas e externas, análise de dados, ações corretivas e preventivas aplicadas as não conformidades, tem se mostrado uma estratégia efetiva para manutenção da qualidade. Assim sendo, implementação desse princípio concorre para o alcance das melhores práticas na radiologia e diagnóstico por imagem. Objeto do estudo: a implementação do princípio gestão da qualidade do programa de acreditação em diagnóstico por imagem, nos serviços de radiologia e diagnóstico por imagem acreditados. Objetivos: conhecer como ocorre a implementação do princípio gestão da qualidade, nos serviços de radiologia e diagnóstico por imagem acreditados; discutir os fatores intervenientes na implementação dos serviços de radiologia e diagnóstico por imagem acreditados; e analisar a participação da enfermagem no princípio gestão da qualidade nos serviços de radiologia e diagnóstico por imagem acreditados. Referencial Teórico: através da tríade de Donabedian, pude compreender melhor como a avaliação periódica, por meio da auditoria interna e externa, além da monitoração constante da conformidade dos requisitos do princípio gestão da qualidade com a cultura, atividades e ações executadas, favorecem sua implementação. Sendo assim, pude criar e vincular os nexos do programa de acreditação em diagnóstico por imagem com o referencial empregado, com o propósito de facilitar o entendimento de que melhorias são contínuas, envolvem o inter-relacionamento da estrutura, processos e resultados de maneira convergente ao atendimento das expectativas do paciente na perspectiva da qualidade e da segurança. Metodologia: abordagem qualitativa, método exploratório realizado em três serviços de radiologia e diagnóstico por imagem ambulatoriais, privados, certificados pelo programa de acreditação em diagnóstico por imagem, na região Sudeste. Os participantes do estudo foram 21coordenadores, de sete setores dos serviços, selecionados de acordo critérios de inclusão e exclusão pré-estabelecidos. A coleta dos dados foi realizada em novembro, dezembro de 2018 e janeiro de 2019, através de entrevistas individuais semiestruturadas e observação não participante no período de julho a setembro de 2019. Análise dos dados: com apoio do software IraMuteq®, o processamento dos textos foi facilitado formando um corpus que permitiu vários cálculos estatísticos sobre as variáveis qualitativas. Para análise textual foi utilizado o método de Reinert, a Classificação Hierárquica Descendente. O projeto de pesquisa foi aprovado pelos Comitê de Ética em Pesquisa da Escola de Enfermagem Anna Nery/Instituto de Atenção à Saúde São Francisco de Assis, conforme parecer 2.741.055. Resultados: a partir do dendrograma, evidenciou-se cinco classes (2,1,4,3,5) produzidas através da identificação do conteúdo lexical de cada uma delas, sua representação fatorial evidenciada pelo seu conteúdo, considerando a força associativa das palavras com a classe onde se encontra, aliado ao meu entendimento e interpretação resultou na seguinte nomeação, respectivamente: o paciente e as fases que envolvem os exames de imagem; a atuação da enfermagem nos exames de imagem com contraste; a preparação do serviço para auditoria externa de acreditação do Padi; as contribuições do programa de acreditação para o serviço e a gestão de risco e da qualidade para a mudança da cultura dos serviços. Conclusão: a implementação do princípio apresentou dificuldades importantes como a cultura praticada nos serviços e as pessoas responsáveis pela execução dos processos, porém com o comprometimento dos colaboradores e das lideranças em permanecer com o certificado da acreditação, e tem dado certo, implementaram requisitos que permitiram a execução de ações diferenciadas na busca da qualidade e da segurança. Entendo que a valorização positiva do erro, é uma excelente oportunidade de aprendizado e consequente meio de prevenção para possíveis danos. A implementação não foi concluída e haverá prosseguimento na sua busca mediante a vigilância da conformidade dos requisitos do princípio, assim sendo, dar-se-á a continuidade das melhorias. E nessa perspectiva a participação da enfermagem, que transitou com sucesso entre as demais equipes de saúde e administrativa, executou ações para mitigação dos riscos, registrando e gerenciando os eventos adversos, atuou em processos educativos, focou eu cuidado na qualidade do atendimento ao paciente e das imagens, na perspectiva da segurança. Demonstrou uma contribuição significativa na implementação do princípio gestão da qualidade, participando da realização periódica da auditoria interna, contribuindo para efetiva implementação e manutenção da gestão da qualidade nos serviços de imagem acreditados.

Quality management has evolved over time and is understood in this study as the essence of imaging services, advocating, through the requirements contained in the diagnostic imaging accreditation program, practices that allow coordinating and controlling the service in order to enable continuous improvement in the structure, processes and results aimed at strengthening the actions that involve the service as a whole, professionals and patients. For this purpose, document management, identification, treatment and monitoring of risks, non-conformities and adverse events are essential, contributing to their mitigation and prevention of occurrence. The periodic evaluation of quality as a system, due to the existing correlation between the prescribed requirements, the results of internal and external audits, data analysis, corrective and preventive actions applied to non-conformities, has proved to be an effective strategy for maintaining quality. Therefore, implementation of this principle contributes to the achievement of best practices in radiology and diagnostic imaging. Object of the study: the implementation of the quality management principle of the accreditation program in diagnostic imaging, in the accredited radiology and diagnostic imaging services. Objectives: to know how the quality management principle is implemented in accredited radiology and diagnostic imaging services; discuss the intervening factors in the implementation of accredited radiology and diagnostic imaging services; and to analyze the participation of nursing in the principle of quality management in accredited radiology and diagnostic imaging services. Theoretical framework: through the Donabedian triad, I was able to better understand how periodic evaluation, through internal and external auditing, in addition to constant monitoring of the compliance of the requirements of the quality management principle with the culture, activities and actions performed, favor its implementation. Therefore, I was able to create and link the links between the accreditation program in diagnostic imaging with the reference framework, with the purpose of facilitating the understanding that improvements are continuous, involving the interrelationship of the structure, processes and results in a convergent way. meeting patient expectations from the perspective of quality and safety. Methodology: qualitative approach, exploratory method carried out in three outpatient radiology and diagnostic imaging services, private, certified by the accreditation program in diagnostic imaging, in the Southeast region. The study participants were 21coordinators, from seven service sectors, selected according to pre-established inclusion and exclusion criteria. Data collection was carried out in November, December 2018 and January 2019, through semi-structured individual interviews and non- participant observation from July to September 2019. Data analysis: with the support of IraMuteq® software, text processing it was facilitated by forming a corpus that allowed for various statistical calculations on qualitative variables. Reinert's method, Descending Hierarchical Classification, was used for textual analysis. The research project was approved by the Research Ethics Committee of the Anna Nery School of Nursing / São Francisco de Assis Health Care Institute, according to opinion 2,741,055. Results: based on the dendrogram, five classes (2,1,4,3,5) were produced, through the identification of the lexical content of each of them, their factorial representation evidenced by their content, considering the associative strength of the words with the class you are in, combined with my understanding and interpretation resulted in the following appointment, respectively: the patient and the phases that involve the imaging exams; the role of nursing in image examinations with contrast; the preparation of the service for Padi's external accreditation audit; the contributions of the accreditation program to the service and the risk and quality management for changing the culture of services. Conclusion: the implementation of the principle presented important difficulties such as the culture practiced in the services and the people responsible for executing the processes, however with the commitment of employees and leaders to remain with the accreditation certificate, and it has worked, implemented requirements that allowed the execution of differentiated actions in the pursuit of quality and safety. I understand that the positive valuation of the error is an excellent learning opportunity and consequent means of prevention for possible damages. The implementation has not been completed and there will be a continuation of its search by monitoring compliance with the requirements of the principle, therefore, the improvements will continue. In this perspective, the participation of nursing, which has successfully passed among the other health teams health and administrative, carried out actions to mitigate risks, recording and managing adverse events, worked in educational processes, focused on the quality of patient care and images, from the perspective of safety.

Evaluation of ionizing radiation as a risk factor for the incidence of breast cancer: long-term analysis after the cesium-137 accident in Goiânia, Brazil. An ecological study

ABSTRACT BACKGROUND: The largest radiological accident to occur in any urban area happened in Goiânia, Brazil, in 1987. OBJECTIVE: To evaluate the association between breast cancer incidence and ionizing radiation levels. DESIGN AND SETTING: Ecological study among residents of the city of Goiânia, Brazil. METHODS: The central region of Goiânia, with seven major sources of contamination from cesium-137, was defined as the study area. The addresses of women diagnosed with breast cancer were identified between 2001 and 2010. The data were geographically referenced and, using census data, the annual averages of crude incidence rates were estimated. The existence of clusters of new cases was ascertained by means of the Moran index. Correlations of radiometric measurements with the incidence were assessed using unconditional linear regression. RESULTS: A total of 4,105 new cases were identified, of which 2,233 were in the study area, and of these, 1,286 (57.59%) were georeferenced. The gross rates of total and referenced cases were 102.91 and 71.86/100,000 women, respectively. These were close to the average for Brazilian state capitals, which is 79.37/100,000 women. The cluster analysis showed slight correlations in three small sets of census tracts, but these were far from the sources of contamination. The scatter plot of points and the R2 value close to zero indicated that there was no association between the variables. CONCLUSION: This study reinforces the hypothesis that the ionizing radiation levels to which women living in Goiânia are now exposed to are not associated with the onset of new cases of breast cancer.

Biplanar imaging with tridimensional capabilities: applicability of this new examination to spinal deformities / Imagem biplanar com capacidade tridimensional: aplicabilidade do novo exame nas deformidades na coluna vertebral / Imagen biplanar con capacidad tridimensional: aplicabilidad del nuevo examen en las deformidades en la columna vertebral

ABSTRACT This study presents details about the applicability of the new image acquisition system, called the biplanar imaging system, with three-dimensional capabilities (EOS®) to the treatment of spinal deformities. This system allows radiographic acquisition of the entire body, with a great reduction in the dose of radiation absorbed by the patient and three-dimensional (3D) stereoradiographic image reconstruction of bone structures, including the spine. In the case of adolescent idiopathic scoliosis, the analysis of the spinal deformity with 3D reconstruction allows better understanding of the deformity and surgical planning. In the case of adult spinal deformity, full-body analysis allows an evaluation of the spinopelvic deformity, including loss of sagittal alignment, in addition to an evaluation of compensatory mechanisms recruited by the individual in an attempt to maintain the sagittal balance. Level of evidence III; Descriptive Review.

RESUMO O presente estudo apresenta detalhes sobre a aplicabilidade do novo sistema de aquisição de imagem, denominado sistema de imagem biplanar, com capacidade tridimensional (EOS®) no tratamento de deformidades da coluna vertebral. Tal sistema permite a aquisição radiográfica do corpo inteiro, com grande redução da dose de radiação absorvida pelo paciente e reconstrução estereoradiográfica em imagem tridimensional (3D) das estruturas ósseas, incluindo a coluna vertebral. No caso de escoliose idiopática do adolescente, a análise da deformidade da coluna vertebral com reconstrução 3D permite a melhor compreensão da deformidade e planejamento cirúrgico. No caso da deformidade da coluna vertebral do adulto, a análise do corpo inteiro permite a avaliação da deformidade espinopélvica, incluindo a perda do alinhamento sagital, além da avaliação adicional dos mecanismos compensatórios recrutados pelo indivíduo na tentativa de manter o equilíbrio sagital. Nível de evidência III; Revisão Descritiva.

Management of pancreatic trauma in adult patients: a single centre experience

Background: Pancreatic trauma is very rare and its management is complex. The aim of this study was to report our experience in the management of pancreatic trauma.Methods: All patients who were admitted with pancreatic trauma from May 2017 to May 2019 were reviewed retrospectively. Demographic data and baseline characteristics were recorded. Grading of pancreatic trauma was carried out according to the American Association for surgery for Trauma (AAST). Data were represented by frequency and mean.Results: A total of 24 patients were admitted with pancreatic trauma in the study period. Road traffic accident (n=17) was the leading cause followed by falls (n=5) and assault (n=2). Out of 24 patients, 3 patients had grade I pancreatic injury, 6 patients had grade II AAST injury, 9 patients had grade III injury and 6 patients had grade IV injury. No patients had grade V injury. Mean hospital stay was 12.3±4.2 days. One patient with grade 2 injury underwent surgery for liver laceration, all others were managed conservatively. Patients with grade 3 and 4 injuries were managed conservatively. One patient with grade 3 injury required, cystogastrostomy for pseudocyst 1 month after the index admission. Two patients of grade 4 injury underwent surgery, one patient for traumatic pseudocyst after 1 month and another patient for bleeding pseudoaneurysm of gastroduodenal artery 1 month after trauma. No patient underwent pancreatectomy. There was no mortality in the study population.Conclusions: Pancreatic trauma can be managed conservatively irrespective of the grade of injury in haemodynamically stable patients.

Semiología Radiológica en Patología Cerebral de Emergencia / Radiological Semiology In Emergency Brain Pathology

La radiología es una gran herramienta en el diagnóstico de patologías encefálicas, especialmente en situaciones de urgencia y emergencia neurológicas, para descartar la presencia de una patología específica, y definir la localización y tamaño de la lesión, o esclarecer un diagnóstico inicial incierto. De esa forma, el conocimiento de sus principales signos, hallazgos y características es importante para realizar un examen adecuado, porque esto facilita la descripción de las imágenes obtenidas con una mayor rapidez y precisión permitiendo una labor óptima e inmediata del médico tratante en favor del paciente. Por ello, este artículo presenta una breve revisión de la semiología radiológica representativa obtenida en la literatura médica, donde las referencias fueron bibliografías e investigaciones, lo cual resulta conveniente para ubicar los signos que pudiese existir apenas fue obtenido el examen, para la futura terapéutica del paciente, así como la posibilidad de ampliación en el examen radiológico o sugerencia del tecnólogo médico de radiología en coordinación con el médico solicitante para garantizar la atención efectiva del paciente.

Radiology is a great tool in the diagnosis of encephalic pathologies, especially in situations of neurological urgency and emergency, to rule out the presence of a specific pathology, and to definite the location and size of the lesion, or clarify an initial uncertain diagnosis. In this way, the knowledge of its main signs, findings and characteristics is important to perform an adequate examination, because it facilitates the description of the images obtained with greater speed and precision allowing an optimal and immediate labor of the treating doctor in favor of the patient. Therefore, this article presents a brief review of the representative radiological semiology obtained in the medical literature, where the references were bibliographies and researches, which is convenient to localize the signs that could exist as soon as the examination was obtained, for the future therapeutic of the patient, such as the possibility of extension in the radiology exam or suggestion by the medical technologist of radiology in coordination with the requesting physician to guarantee the patient's care effective.

Determinants of calcified placenta and its association with fetal outcome among mothers who gave birth in Southern Ethiopia, 2018

Background: Placenta is a complex multifunctional organ that maintains pregnancy and promotes normal fetal development. Fetal outcome is adversely influenced by pathological changes in placenta because it is a mirror which reflects intrauterine status of fetus. Placental abnormalities are considered as leading cause of maternal and perinatal mortality. Objective of the study was to assess determinants of calcified placenta and its association with fetal outcomes.Methods: Institutional based unmatched case-control study was conducted on 213 placentas from mothers who gave birth at Dilla university referral hospital with an age range of 19-34 years. Calcifications were assessed radiologically and graded according to Grannum. Bivariate logistic regression analysis was identified and fitted to the multiple logistic regression analysis to identify the independent effects of each variable to the outcome variable. Chi-square test was used to find the potential association between grade two and above levels of calcification and fetal outcomes.Results: Total 213 singles parturient with their placenta above 37 weeks gestational age were included. The likelihood of developing grade two and above level of calcification associated with the following variables: educational status (OR=3.134; 95%CI: 1.208, 8.135),parity (OR 3.125; 95% CI: 1.354, 7.213) ,maternal anemia (OR 6.834;95%C: I2.626,17.803), smoking (OR 6.343;95% CI: 2.624,15.334),  abruption (OR 6.046;95% CI: 2.392,15.277), and pregnancy- induced hypertension (OR 4.868 ;95% CI: 2.095,11.354). In this study, neonatal outcomes in grade II and above level of calcification were poorer than grade I and bellow level of calcification in chi-square association test.Conclusions: Grade II and above level of placental calcification (case) was significantly associated with maternal pregnancy-induced pathologies, number of parity, maternal educational status, and results in different kind of anomalies, maternal and neonatal mortality. Therefore, the practice of placental examination before and after birth guarantees for feto-maternal wellbeing.

Evaluación de resultados radiográficos en población geriátrica con hallux valgus grado moderado a severo intervenido con técnica quirúrgica de Lelièvre y Vidalot / Evaluation of radiographic results in geriatric population with moderate to severe degree hallux valgus intervened with surgical technique of Lelièvre and Vidalot

Resumen: Antecedentes: Hallux valgus (HV) es una desviación en valgo de la articulación metatarsofalángica y en varo del primer metatarsiano. La cirugía pretende reestablecer la congruencia articular, corregir la deformidad y disminuir el dolor. Existe poca literatura de los resultados en población geriátrica. El propósito de este estudio es demostrar que la técnica quirúrgica abierta de Lelièvre y Vidalot logra resultados radiográficos aceptables en dicha población. Material y métodos: 68 pacientes entre 60 y 85 años intervenidos con técnica Lelièvre y Vidalot por HV moderado a severo de Isham, entre Enero 2014 y Enero 2017. Se evaluaron las radiografías preoperatoria, postoperatoria inmediata y a los seis meses, con radiometría convencional para esta afección; todas las mediciones se realizaron en sistema digital. Los datos se ingresaron en Microsoft Excel. Los valores de p < 0.05 se consideraron estadísticamente significativos. Resultados: De 68 pacientes (54 mujeres y 14 hombres), edad media 68.0 años, 12 presentaron afectación bilateral; 28 segundo dedo en garra. El ángulo metatarsofalángico con una media preoperatoria fue 36.6o, incrementado en 100% de los casos de ángulo intermetatarsal 1-2, existiendo una correlación p < 0.05 entre ángulo intermetatarsal y aumento del ángulo metatarsofalángico. Los resultados postquirúrgicos inmediato y a seis meses presentaron una correlación p = 0.3107. Conclusiones: El tratamiento de HV moderado a severo en nuestra población geriátrica bajo técnica Lelièvre y Vidalot logra una corrección aceptable demostrada radiográficamente en el postoperatorio inmediato y a los seis meses, esto traduce una opción viable de tratamiento quirúrgico en dicha población.

Abstract: Background: Hallux valgus (HV) defines a valgo deviation from the metatarsophalangeal joint and in a varo of the first metatarsal. The surgery aims to restore joint congruence, correct deformity and decrease pain. There is little literature on the results in the geriatric population. The purpose of this study is intended to demonstrate that the open surgical technique of Lelièvre and Vidalot achieves acceptable radiographic results in that population. Material and methods: 68 patients between 60 and 85 years of age were involved with Lelièvre Technique and Vidalot for moderate to severe HV of Isham, between January 2014 and January 2017. Immediate postoperative and six month radiographs were evaluated with conventional radiometry for this condition; All measurements were made in digital system. The data was entered in Microsoft Excel. p values < 0.05 were considered statistically significant. Results: Out of 68 patients (54 women and 14 men), average age 68.0 years. 12 had bilateral concern. 28 second finger claw. The metatarsphasopalangic angle with a preoperative mean was 36.6o, increased by 100% of cases of intermetatarsal angle 1-2, with a correlation p < 0.05 between intermetatarsal angle and metatarsal angle increase. Immediate and six-month post-surgical results with a correlation of p = 0.3107. Conclusions: The treatment of moderate to severe HV in our geriatric population under technique Lelièvre and Vidalot achieves an acceptable correction demonstrated radiographically in the immediate postoperative period and at six month, this translates a viable option of surgical treatment in these population.

A modified technique for tibial bone sparing in unicompartmental knee arthroplasty / 中华医学杂志(英文版)

Background@#Previously, the authors modified the surgical technique to preserve tibial bone mass for Oxford unicompartmental knee arthroplasty (UKA). The purpose of this study was to determine the clinical outcomes and values of this modified technique.@*Methods@#Clinical data of 34 consecutive patients who underwent the unilateral modified UKA technique (modified group, 34 knees) were retrospectively analyzed. To compare the outcome, a match-paired control group (conventional group, 34 knees) of an equal number of patients using the conventional technique system in the same period were selected and matched with respect to diagnosis, age, pre-operative range of motion (ROM), and radiological grade of knee arthrosis. Clinical outcomes including knee Hospital for Special Surgery (HSS) score, ROM, and complications were compared between the two groups. Post-operative radiographic assessments included hip-knee-ankle angle (HKA), joint line change, implant position, and alignment.@*Results@#The mean follow-up time was 38.2 ± 6.3 months. There was no difference in baseline between the two groups. The amount of proximal tibial bone cut in the modified group was significantly less than that of the conventional group (4.7 ± 1.1 mm vs. 6.7 ± 1.3 mm, t = 6.45, P < 0.001). Joint line was elevated by 2.1 ± 1.0 mm in the modified group compared with -0.5 ± 1.7 mm in the conventional group (t = -7.46, P < 0.001). No significant differences were observed between the two groups after UKA with respect to HSS score, VAS score, ROM, and HKA. Additionally, the accuracy of the post-operative implant position and alignment was similar in both groups. As for implant size, the tibial implant size in the modified group was larger than that in the conventional group (χ2 = 4.95, P = 0.035).@*Conclusions@#The modified technique for tibial bone sparing was comparable with the conventional technique in terms of clinical outcomes and radiographic assessments. It can preserve tibial bone mass and achieve a larger cement surface on the tibial side.
