The present study aimed to investigate the utility of the proximal femur in the forensic age estimation by assessing changes in bone densities through radiographs. Using Otsu's threshold, bone density was quantified by counting all white pixel values within selected regions of interest, which include femoral head (FH), femoral neck (FN), Ward's triangle (WT), and greater trochanter (GT) from 354 left femora of Northern Thai descent. The pixel width of medullary cavity (MC) was also estimated. Furthermore, the study evaluated the performance of linear regression (LR) models for age estimation from radiographic images of proximal femora. Negative correlations were observed between FH, FN, WT, and GT pixel intensity with the age-at-death of the samples, with females exhibiting stronger correlations than males. Moreover, a positive correlation was found between age and MC width in female samples, while male MC widths did not show any relationship with increasing age. The results showed a slight difference between the LR model applied to both sexes, which integrated all variables, and the alternative configuration that only utilized relevant attributes. Both models exhibited similar performance, with a narrow range of root mean square error (RMSE) values, ranging from 12.67 to 12.71 years, and a correlation coefficient range of 0.51 to 0.52. For females, the LR model with FN and WT as selected attributes (RMSE = 11.85 years, correlation coefficient = 0.65) performed decently, while for males, the LR model with all variables showed RMSE of 12.52 years and correlation coefficient of 0.46. This study showcased the potential application of pixel intensity in predicting age. [ABSTRACT FROM AUTHOR]

Introduction: Peripheral trauma is a very frequent cause of consultation in paediatric emergency departments but few studies have been published describing the characteristics of these patients. Material and methods: We performed a retrospective descriptive study by reviewing computerised emergency department forms during January and February 2020. Objective: To describe the characteristics of traumatic injuries in our area and to detect possible areas for improvement. Results: A total of 714 peripheral trauma cases were attended, which represents 9.5% of the total consultations. A total of 52.7% were schoolchildren (6–11 years). The most frequent locations were the ankle (27.5%) and fingers (17.2%). Fracture was detected in 6.7% of cases. Radiographs were requested in 78.6% of the patients, with pathological findings in 9.6% of them. Half of the X-rays were requested due to ankle or finger trauma. Referral to traumatology was made in 16.4% of patients, mainly for elbow and knee trauma, and the most commonly used treatment was general measures (49%) and bandaging (29.4%). Conclusions: Peripheral trauma is very common and, in general, banal. A large number of X-rays are requested with a very low yield, so it seems necessary to establish new protocols to reduce the number of requests. Improving training in elbow and knee trauma could improve paediatricians’ autonomy in dealing with these more complex injuries. Resumen: Introducción: Los traumatismos periféricos son una causa muy frecuente de consulta en las urgencias pediátricas, pero apenas se han publicado estudios que describan las características de estos pacientes. Material y métodos: Se realiza un estudio descriptivo retrospectivo mediante revisión de formularios informatizados de urgencias pediátricas durante los meses de enero y febrero de 2020. Objetivo: Conocer las características de la patología traumática pediátrica de nuestra área y detectar posibles puntos de mejora. Resultados: Se atendieron 714 traumatismos periféricos, lo que supone 9,5% de las consultas totales. De los pacientes presentados, 52,7% fueron escolares (seis a 11 años). Las localizaciones más frecuentes fueron el tobillo (27,5%) y los dedos de la mano (17,2%). Se detectó fractura en 6,7% de los casos. En 78,6% de los pacientes se solicitó radiografía, siendo patológica 9,6% de las mismas. La mitad de las radiografías se solicitaron por traumatismo en el tobillo o dedos de la mano. Se realizó interconsulta a traumatología en 16,4% de los pacientes, sobre todo en traumatismos de codo y rodilla, y el tratamiento más empleado fueron las medidas generales (49%) y el vendaje (29,4%). Conclusiones: Los traumatismos periféricos son muy habituales y, en general, banales. Se solicita un gran número de radiografías con una rentabilidad muy baja, por lo que parece necesario establecer nuevos protocolos que permitan reducir el número de peticiones. Mejorar la formación respecto a los traumatismos de codo y rodilla podría mejorar la autonomía de los pediatras respecto a este tipo de lesiones, más complejas.

Relevance. For more than 100 years, medical practice has used imaging methods to observe pathological changes localized in the human body. The first method was radiography, which became popular among doctors, but later it turned out that high radiation exposure increases the incidence of tumor diseases, which is why standards for permissible radiation doses were developed for patients and radiologists. The introduction of radiocontrast agents also had contraindications that should be taken into account. Ultrasound, computed tomography (CT), magnetic resonance imaging (MRI), and angiography methods have significantly increased the diagnostic capabilities of instrumental methods. The purpose of this review is to analyze the advantages and disadvantages of modern imaging methods in medicine. Methods. To achieve the purpose of the review, a literature search was conducted in Google Scholar and PubMed databases. Results. 1) The main indication for the X-ray method is visualization of bone structures. 2) X-ray contrast methods are optimal for studying hollow organs and blood vessels. 3) The advantage of MRI is the ability to visualize soft tissue well. 4) CT helps to reconstruct the spatial architecture of organs. 5) Ultrasound allows you to observe the condition of the embryo and fetus, as well as internal organs.

Background: In Mexico and the world, breast cancer is the cancer type with the highest incidence and mortality for women. Its incidence has increased due to a higher life expectancy and a higher exposure to risk factors. Screening is done by mammography using the BIRADS (Breast Imaging Reporting and Data System) system, the standard for mammography screening report which classifies lesions assigning recommendations for patient follow-up. The system goes from 0 (not conclusive) to 6 (demonstrated malignancy), being of interest for this study the BIRADS 0 category. Objective: To describe patients classified as BIRADS 0 by mammography and their reclassification in a first-level hospital during 2021. Material and methods: Retrospective, descriptive, crosssectional, observational study. Women over 40 years with a BIRADS 0 result were studied. The following databases were used: Institutional Cancer Registry, Family Medicine Information System, Electronic Clinical File, and the mammography and patient list from preventive medicine. Results: Reclassification by ultrasound (US) was achieved in 100% of patients, in all of the BIRADS US categories. In 3.8% of BIRADS 0 patients, ductal adenocarcinoma was found and confirmed by histological testing. Conclusion: All of the reassessed lesions with US were adequately reclassified.

The Psittacidae family is made up of several species. Among the native species in Brazil, the Caatinga parakeet (Eupsittula cactorum) is found abundantly in the Caatinga and Cerrado biomes. In the respiratory system, there are certain structural particularities, this system represents a significant target for infections or impairment related to creation, with radiology being an important tool in the evaluation of these anatomical structures and in the diagnosis of pathologies. Thus, the use of radiography in monitoring a case of pneumonia in a Caatinga parakeet was crucial in determining its progression. After the prescribed treatment, a second radiograph was taken, and, together with the clinical evaluation of the animal upon return, it was confirmed that the treatment was effective.

The twister, an unconventional pet, requires careful sanitary management to avoid vulnerability to specific agents, especially those affecting the respiratory system. Untreated cases can evolve into severe situations that may become emergencies, and chest radiography is essential to determine the appropriate intervention. In this way, a twister was brought in for clinical care with dyspnea, was referred for hospitalization, and after stabilization underwent a chest radiograph that revealed pneumothorax and atelectasis. The animal underwent a relieving thoracentesis, showing a considerable clinical improvement. Unfortunately, it succumbed to its condition hours later. [ABSTRACT FROM AUTHOR]

A osteomielite é uma doença infecciosa sistêmica grave, caracterizada pela inflamação óssea destrutiva e progressiva, que geralmente possui origem bacteriana, e, ocasionalmente, viral ou fúngica. Objetivou-se relatar o caso de um cão com osteomielite fúngica, detalhando o diagnóstico e a evolução do tratamento. Foi atendido no Hospital Veterinário da Universidade Federal de Uberlândia (HOVET-UFU) um cão, macho, 8,9 kg, mestiço, quatro meses de idade, apresentando hipertermia, hiporexia, linfonodos reativos, claudicação e ferida aberta em membro torácico direito (MTD), além de secreção purulenta e exposição óssea. A radiografia evidenciou fraturas Salter Harris I em cartilagens fisárias da ulna direita e sinais de lesão óssea agressiva poliostótica em MTD. As culturas fúngica e bacteriana isolaram Enterococcus sp., Penicillium sp. e Acremonium sp. O diagnóstico obtido foi osteomielite fúngica. Com base no antibiograma e antifungigrama, foram utilizados os fármacos amoxicilina com clavulanato de potássio, omeprazol e itraconazol e o animal foi acompanhado radiograficamente a cada 30 dias. Após 150 dias os sinais de remodelamento ósseo da articulação e ossos adjacentes eram mais evidentes e o tratamento foi finalizado. O cão permaneceu por 28 meses livre de recidivas. Ressalta-se que a conduta médica diante de uma ferida não deve ser direcionada somente à cicatrização, sendo necessária a realização de radiografia e, em casos de suspeita de osteomielite, exames para exclusão dos diagnósticos diferenciais, bem como, para a escolha do fármaco mais eficaz em cada caso.

Resumen Introducción y objetivo. En los casos de rinoplastia con desviación septal, el diagnóstico clínico por parte del especialista es parte medular de la conducta a tomar, ya sea clínica o quirúrgica, debido a que la obstrucción nasal que suele ocasionar esta patología es uno de los síntomas más frecuentes, siendo esta la primera indicación de cirugía nasal no estética. El objetivo del presente trabajo es determinar la concordancia entre el diagnóstico clínico y radiográfico en pacientes sometidos a septoplastia en una clínica especializada de Lima, Perú, durante el periodo 2020 - 2021. Material y método. Estudio observacional, cuantitativo, analítico de concordancia retrospectivo. Mediante muestreo no probabilístico por conveniencia, se toman todos los pacientes con diagnóstico clínico de desviación septal y estudios radiográficos intervenidos quirúrgicamente de septoplastia en dicho centro, obteniendo 124 historias clínicas que cumplieron los criterios de inclusión. Se calculó el porcentaje de concordancia entre estas dos métricas y se estimaron las estadísticas kappa de Cohen ponderadas y no ponderadas en todas las muestras y luego por configuración. Resultados. Con una media de 33 años de edad, encontramos que la mayoría eran mujeres (55.28%) sin predilección por el grado de desviación significativa. El diagnóstico clínico que predominó fue grado moderado (54.84%) y el diagnostico radiológico, el severo (49.19%). La gnosología principal fue la congénita (38.8%), seguida de la adquirida (34.7%); aun así, no existe relación significativa entre el sexo y el tipo de desviación encontrada. Encontramos concordancia insignificante entre el diagnóstico clínico y el radiográfico en todas sus formas. Conclusiones. En nuestro estudio, no hubo concordancia entre el diagnóstico clínico y radiológico con respecto al grado o severidad de la desviación septal.

Objective: To develop a convolutional neural network (CNN) model, trained with the Brazilian "Estudo Longitudinal de Saúde do Adulto Musculoesquelético" (ELSA-Brasil MSK, Longitudinal Study of Adult Health, Musculoskeletal) baseline radiographic examinations, for the automated classification of knee osteoarthritis. Materials and Methods: This was a cross-sectional study carried out with 5,660 baseline posteroanterior knee radiographs from the ELSA-Brasil MSK database (5,660 baseline posteroanterior knee radiographs). The examinations were interpreted by a radiologist with specific training, and the calibration was as established previously. Results: The CNN presented an area under the receiver operating characteristic curve of 0.866 (95% CI: 0.842-0.882). The model can be optimized to achieve, not simultaneously, maximum values of 0.907 for accuracy, 0.938 for sensitivity, and 0.994 for specificity. Conclusion: The proposed CNN can be used as a screening tool, reducing the total number of examinations evaluated by the radiologists of the study, and as a double-reading tool, contributing to the reduction of possible interpretation errors.

Introduction: COVID-19 has imposed a challenge for health services, from an economic and social point of view. The role of chest radiography has been fundamental in the management of these patients. Objective: To characterize the most frequent radiological findings in patients confirmed to COVID-19. Methods: A descriptive study was carried out in 859 admitted patients, confirmed to COVID-19, who presented radiological lesions during their hospital stay; chest X-rays were taken on admission and during evolution, according to the protocol of care in force at the time of the study. The variables used were: Age, biological sex, severity of the radiological picture, radiological pattern and location of the lesions. Results: Adults (65.7%), males (60.4%), were more frequent; moderate severity lesions predominated (51.6%); only 17.4% evolved to severe radiological forms. 64.8% showed mixed radiological pattern; with higher frequency in bilateral (89.9%), peripheral/subpleural (66.7%) and in lower fields (90.9%). Conclusions: Radiological findings are characterized by presenting lesions of moderate severity, with mixed pattern, in bilateral, peripheral/subpleural and in inferior fields locations.

Fraturas de ossos longos possuem elevada casuística na rotina clínica de grandes animais. Isso ocorre, devido a territorialidade, índole e manejo do rebanho. Majoritariamente, estes animais acometidos são submetidos a eutanásia, devido ao baixo valor zootécnico ou alto valor agregado no tratamento do animal. Neste cenário, este trabalho relata o caso de um ovino macho reprodutor, da raça Santa Inês atendido na Clínica Escola da Pontifícia Universidade Católica de Goiás (PUC, Goiás) devido a incapacidade de apoiar-se com o membro posterior esquerdo, concomitantemente, com presença de região edemaciada, após um episódio de briga com outro reprodutor. Foi constatado, pela radiografia, a presença de fratura fechada multifragmentada na região de tíbia e fíbula do membro pélvico esquerdo. Foi realizada analgesia com meloxicam (0,6 mg/kg intravenoso, por três dias consecutivos), imobilização com gesso e bandagens por 21 dias. Após este período, foi constatado a instabilidade da contenção pelo exame radiográfico e foi realizada uma nova abordagem com muleta de Thomas durante 37 dias. Passado este período, nova radiografia foi realizada constatando a síntese óssea com presença de calo ósseo. A muleta foi retirada e o animal não apresentou dificuldade ao caminhar, alimentar-se, deitar-se, além de não comprometer a função reprodutiva. Sendo assim, a utilização deste método de imobilização confirma a possibilidade para o tratamento de fraturas para animais de produção, visto que pequenos ruminantes possuem boa capacidade para regeneração óssea e devido ao baixo custo para produção, manutenção e facilidade de aplicação da muleta de Thomas.

Osteoarthritis of the knee is a very common degenerative arthropathy, especially among the elderly, but also present in young adults, as a consequence of overweight and strenuous work or sports activity; this primary form is distinguished from the secondary form, resulting from other pathologies involving the articular surfaces of the knee such as fracture outcomes, osteonecrosis, infections, and femoral, tibial, and patellar malformations. Among the commonly used imaging techniques, the most effective in the evaluation of knee osteoarthritis are MRI and conventional radiology: both provide a wealth of information and highlight various pathological features affecting cartilage, joint spaces, and subchondral bone. A recent review compared the data obtained from preoperative X-ray and MRI examinations with the results of arthroscopic examinations, performed at Outside Facilities, over a period of about five years, to evaluate the reliability of these imaging techniques, in predicting the actual severity of observed knee osteoarthritis.

Background and objective. In cases of rhinoplasty with septal deviation, the clinical diagnosis by the specialist is a core part of the conduct to be taken, whether clinical or surgical, because nasal obstruction, which is usually caused by this pathology, is one of the most frequent symptoms, this being the first indication of non-aesthetic nasal surgery Objective. To determine the concordance between clinical and radiographic diagnosis in patients undergoing septoplasty in a specialized clinic in Lima, Peru, during the period 2020 - 2021. Methods. Observational, quantitative, retrospective, analytical study of concordance. By non-probabilistic sampling by convenience, all patients with clinical diagnosis of septal deviation and radiographic studies who underwent septoplasty surgery in our clinic were considered. A total of 124 medical records were obtained that met the inclusion criteria. The percentage of concordance between these two metrics was calculated, and we estimated weighted and unweighted Cohen's kappa statistics across all samples and then by configuration. Results. With a mean age of 33 years, it was found that the majority were women (55.28%) without a predilection for the degree of significant deviation; the predominant clinical diagnosis was moderate degree (54.84%) and the radiological diagnosis was severe (49.19%). The main gnosology was congenital (38.8%), followed by acquired (34.7%), even so, there is no significant relationship between sex and the type of deviation found. An insignificant concordance was found between clinical and radiographic diagnosis in all its forms. Conclusions. In our study, there was no concordance between clinical and radiological diagnosis with respect to the degree or severity of septal deviation. [ABSTRACT FROM AUTHOR]

This guide provides help for medical doctors systematically identifying each commercial brand of pacemakers by thoracic radiography through their electronic components (electrode connectors, logic circuit, and battery); this is crucial for watching the pacemaker after being implanted. We aimed to describe the different cardiac stimulation devices, electrodes, and programming modes more frequently used. [ABSTRACT FROM AUTHOR]

Acromegaly is an uncommon metabolic disorder, often diagnosed after a long delay. One symptom seen in many patients with acromegaly is arthralgia, a finding that calls for the use of conventional radiography, which can reveal subtle changes that can go unnoticed. The objective of this pictorial essay is to portray the radiographic aspects of acromegaly, seeking to demonstrate the importance of conventional radiography, which, despite its simplicity, can suggest the diagnosis, even in the early stages, thus altering the clinical course of the disease.

A ruptura diafragmática é uma condição em que ocorre o rompimento do diafragma, resultando no deslocamento das vísceras abdominais para a cavidade torácica. Pode ser de origem congênita ou traumática e seu diagnóstico geralmente é realizado através da radiografia, onde a intervenção cirúrgica é o tratamento mais adequado. O caso descreve um cão, SRD, macho, levado à clínica veterinária após acidente automobilístico. O animal foi internado e liberado com prescrição de medicamentos, visto que, os exames de imagem não apresentaram alterações. Após a manifestação de diversos sintomas e com uma nova radiografia, foi diagnosticada a ruptura diafragmática. Submetido à cirurgia, a recuperação de excelência tornou o prognóstico favorável.

Quando comparada com as demais radiografias simples, a imagem radiográfica da mama é a que requer o mais alto padrão técnico na sua execução. Isto se deve à própria estrutura dos tecidos que compõem o órgão (tecidos de densidades muito semelhantes) e à geometria bastante particular com que ele é radiografado (compressão e localização rigorosas e uso de ampliação). Além disso, como o exame radiográfico da mama é um dos métodos utilizados no diagnóstico precoce do câncer, é necessário que seja realizado dentro de um nível bastante reduzido de risco decorrente da radiação. Desta forma, a exposição de mulheres sadias para o exame radiográfico da mama requer que o risco seja o mínimo compatível com uma imagem de alto padrão de qualidade.

El éxito del tratamiento de la displasia del desarrollo de la cadera está íntimamente ligado a una intervención temprana, o sea, a un diagnóstico y tratamiento precoces y seguros. El estudio radiográfico tradicionalmente se ha sustentado en la medición de una serie de parámetros, la cual se realiza mediante el goniómetro, marcando directamente en la radiografía. Sin embargo, este procedimiento tiene sus desventajas. El presente estudio tiene como objetivo exponer las características de una plantilla para medir la cadera con desarrollo displásico en el lactante. Se explica cómo proceder con la herramienta propuesta; se argumentan sus posibilidades y metodología de aplicación, y se ilustra su factibilidad desde el punto de vista práctico. La plantilla permite evaluar la cadera del lactante, independientemente de la osificación del núcleo de la cabeza del fémur; así como determinar si la cadera es normal; y en caso de ser patológica, clasificarla en dependencia del grado de severidad de la afección.

Introdução: Os efluentes radiográficos no campo da saúde são originados do processamento das radiografias, que utilizam soluções reveladoras e fixadoras contendo substâncias danosas ao meio ambiente e à saúde humana. Objetivo: Identificar na literatura as evidências nacionais e internacionais sobre as formas de descarte de efluentes radiográficos provenientes de serviços de saúde. Método: Trata-se de uma revisão integrativa da literatura realizada nas bases de dados Biblioteca Virtual em Saúde (BVS), U.S. National Library of Medicine (PubMed) e Scientific Electronic Library Online (SciELO). Selecionou-se 14 evidências científicas publicadas entre 1995 e 2020. Resultados: A maioria dos estudos mostrou que o descarte dos efluentes radiográficos foi realizado de forma inadequada, preferencialmente em esgotos sanitários sem nenhum tratamento. Poucas evidências apontaram para a recuperação da prata presente nos efluentes e o seu envio para o tratamento e a disposição final por empresas especializadas. Apenas uma pesquisa brasileira mostrou que o descarte desses efluentes foi realizado seguindo os padrões estabelecidos pelos órgãos regulamentadores. Conclusões: A partir das evidências encontradas, verificou-se que o descarte dos efluentes radiográficos ainda se configura como um problema mundial ambiental, uma vez que estabelecimentos produtores desses resíduos não seguem as legislações para o descarte correto e tratamento, sendo recomendada a substituição pela tecnologia digital.

Las imágenes médicas de la anatomía maxilofacial pueden ser consideradas como una de las más difundidas e importantes en la imagen diagnóstica de la actualidad. Una imagen del aparato masticatorio es relevante desde el punto de vista de la medicina, para tratamientos tan comunes como una ortodoncia hasta tratamientos complejos como un implante óseo. Actualmente los tipos de imágenes para diagnóstico más utilizadas en este campo son la Radiografía Panorámica Tradicional en el campo de la Ortopantomografía (OPG) y la Tomografía Computada (CT). Los odontólogos y médicos actuales solicitan este tipo de exámenes médicos para hacer diagnóstico de enfermedades, lesiones o estudios previos a los tratamientos. Dado que estas imágenes médicas son las más comunes y difundidas, es importante conocer que características, ventajas y desventajas ofrecen cada una de ellas en el contexto de la odontología y que aplicaciones clínicas específicas existen para OPG y CT. En esta investigación se expondrá también temas poco estudiados en las imágenes médicas del sistema maxilofacial y odontológicas, como lo es el cálculo de dosis y protección radiológica tanto en OPG como en CT. Se expondrá brevemente también, aspectos básicos de la calidad de imagen en ambos tipos de obtención de imagen. Finalmente se expone una comparación entre ambos métodos.

To identify differential features between patients with seropositive and seronegative rheumatoid arthritis (RA). Prospective cohort study, including patients who were admitted for polyarthralgia. At baseline was performed: laboratory studies, X -rays of hands and feet, ultrasound of both hands with power Doppler technique, clinical data and clinimetry. In subsequent visits the definitive diagnosis of RA was established or not. It was considered as seronegative RA when patients were negative for both RF and ACPAs. 746 patients were included, of which 128 (17.1%) ended with a final diagnosis of RA. Of these 128 patients, 87 (67.9%) were seropositive RA, while 41 (32%) were seronegative RA. The only feature that showed significant differences was the presence of tenosynovitis detected by ultrasound with a positive power Doppler signal, 13.7% of the patients with seropositive RA vs 41.6% of the patients with seronegative RA (p = 0.0028). The only differential feature of patients with seronegative RA was the higher proportion of tenosynovitis detected by ultrasound. [ABSTRACT FROM AUTHOR]

The approach to infectious diseases ranges from identification of the etiologic agent to treatment. In pneumonia, diagnostic tools are diverse; such as computed axial tomography, chest radiography and recently lung ultrasound (LUS), each with advantages and disadvantages. For this reason, we set out to systematically review the literature on the diagnostic accuracy of PU in the detection of community-acquired pneumonia (CAP) in adult patients, and to determine whether it is an optimal diagnostic tool. MEDLINE, CENTRAL and LILACS databases were searched. The quality of the included articles was determined using the "QUADAS-2" tool. The sensitivity and specificity of the UP were 82.8%-100% and 61.1%-98.7%. Chest X-ray sensitivity was 47%-72.7%, and specificity was 50%. Inter-observer agreement was determined with a range for the index κ = 0.79-0.88 for UP. In this study it was demonstrated that the UP used for the diagnosis of CAP has a better performance in terms of sensitivity and specificity; in addition, its low cost, availability, convenience and absence of ionization, ensures the usefulness of this diagnostic tool (PROSPERO ID 332552).

O objetivo desse estudo foi determinar o valor de VHS em cães de raças braquicefálicas clinicamente normais com objetivo de determinar parâmetros de normalidades para raças com essa característica. O método Vertebral Heart Size (VHS) efetua a mensuração do tamanho cardíaco comparando as vertebras torácicas afim de auxiliar em diagnostico de insuficiência cardíacas e cardiomegalias. A radiografia de tórax possui uma importância na clínica medica de pequenos animais, trazendo informações para avaliações de órgãos intratorácicos, assim como a capacidade de efetuar avaliação da silhueta cardíaca. As radiografias foram avaliadas de acordo o proposto por Buchanan & Bücheler (1995), mensurando a silhueta cardíaca e profundidade, e largura do tórax. Os valores médios obtidos para VHS foram de 9,57±059v, sendo o menor valor mensurado de 8,5v e maior 10,5v. A especificação averiguou valores divergentes quando comparado com o estudo dos autores. Confirmando assim, a necessidade de determinação de valores de VHS específicos para raças com características de braquicefalia.

Introdução: O sequestro pulmonar é uma anomalia congénita rara. Pode ser definido como uma massa de tecido pulmonar composto por tecido embrionário cístico e alvéolos não arejados e desorganizados, sendo classificado como sequestro intralobar (SIL) ou sequestro extralobar (SEL). O SIL tem maior incidência, com igual distribuição relativamente ao sexo. Costuma apresentar manifestações clínicas mais tardias, geralmente por infeções respiratórias recorrentes, hemoptises e dispneia. O SEL tem menor prevalência, afeta maioritariamente o sexo masculino, sendo o seu diagnóstico mais precoce. O tratamento de eleição é a resseção cirúrgica do tecido pulmonar sequestrado, com bom prognóstico. Descrição do Caso: Mulher de 39 anos, raça caucasiana, que trabalhava em artes plásticas. Com antecedentes pessoais de rosácea e tuberculose pulmonar, sem medicação habitual ou alergias. Referia hábitos tabágicos e alcoólicos socialmente. Iniciou quadro de tosse seca e febre vespertina, com cerca de quinze dias de evolução, o que a fez recorrer à médica de família (MF), em 30/11/2020, D15, tendo sido pedida uma radiografia do tórax de incidência póstero-anterior e análises. Dirigiu-se ao serviço de urgência (SU), D43, por manutenção dos sintomas, onde foi medicada com azitromicina 500mg id, 3 dias, desloratadina 5mg id, 20 dias, e prednisolona 5mg, bid, 4 dias. Por ausência de melhoria, e após ter recorrido novamente ao SU, recorreu à sua MF onde continuou o estudo e foi referenciada para consulta de pneumologia, tendo sido diagnosticado sequestro pulmonar. Foi encaminhada para cirurgia torácica, tendo efetuado lobectomia. Atualmente, em seguimento pós-cirúrgico, com remissão da sintomatologia e bom prognóstico. Comentário: A investigação etiológica da sintomatologia desta doente colmatou com um diagnóstico improvável de sequestro pulmonar. Este caso realça a relevância do papel dos métodos de imagem neste tipo de patologias e a importância de uma boa articulação entre os cuidados de saúde primários e secundários, através de uma célere referenciação.

Introduction: Peripheral trauma is a very frequent cause of consultation in paediatric emergency departments but few studies have been published describing the characteristics of these patients., Material and Methods: We performed a retrospective descriptive study by reviewing computerised emergency department forms during January and February 2020., Objective: To describe the characteristics of traumatic injuries in our area and to detect possible areas for improvement., Results: A total of 714 peripheral trauma cases were attended, which represents 9.5% of the total consultations. A total of 52.7% were schoolchildren (6-11 years). The most frequent locations were the ankle (27.5%) and fingers (17.2%). Fracture was detected in 6.7% of cases. Radiographs were requested in 78.6% of the patients, with pathological findings in 9.6% of them. Half of the X-rays were requested due to ankle or finger trauma. Referral to traumatology was made in 16.4% of patients, mainly for elbow and knee trauma, and the most commonly used treatment was general measures (49%) and bandaging (29.4%)., Conclusions: Peripheral trauma is very common and, in general, banal. A large number of X-rays are requested with a very low yield, so it seems necessary to establish new protocols to reduce the number of requests. Improving training in elbow and knee trauma could improve paediatricians' autonomy in dealing with these more complex injuries., (Copyright © 2024 SECOT. Publicado por Elsevier España, S.L.U.

El presente artículo propone una prueba de concepto para la observación mediante técnicas de imagen multibanda de 63 pigmentos de referencia histórica (usados desde la Antigüedad hasta el siglo XX). La respuesta de estos pigmentos se ha documentado en varios puntos de espectro mediante la construcción de sus imágenes, por reflexión, transmisión, luminiscencia y falso color, desde el visible (VIS) hacia sus dos extremos, ultravioleta (UV) e infrarrojo (IR), completando además el estudio con la imagen radiográfica (RX). Cada pigmento responde de manera diferente en cada una de las técnicas usadas, en función de su comportamiento espectral, lo que genera un patrón de conducta único para cada materia. El conjunto de técnicas utilizadas conforma una metodología que plantea 11 posibles formas de ver, entendiéndolas de manera aislada, si bien es en la lectura transversal y confrontación de todas ellas donde se alcanzan unos resultados más completos, a través de un método inductivo basado en la observación. Se trata de un estudio de carácter novedoso que, aunque cuenta con precedentes aislados, compendia por primera vez en forma de imágenes, el aludido comportamiento espectral de tales pigmentos. Así, los resultados obtenidos pretenden contribuir a la mejorar la lectura e interpretación de los análisis no invasivos por imagen aplicados a obras pictóricas, permitiendo la identificación preliminar de algunos pigmentos.
