ABSTRACT

Las fracturas con hundimiento de cráneo intrauterinas representan una entidad poco frecuente, generalmente secundaria a traumatismos (previos o durante el nacimiento) o de etiología desconocida. Suelen requerir evaluación y seguimiento por el servicio de Neurocirugía Pediátrica. A la fecha, es controversial la necesidad de tratamiento quirúrgico y el momento oportuno para concretarlo. Se presentan dos casos clínicos de pacientes de término, nacidas porcesárea,condiagnósticoposnatalinmediatodehundimiento de cráneo de tipo ping-pong no traumático. Ambas pacientes presentaron examen neurológico normal. Se confirmó el diagnóstico a través de radiografía y tomografía de cráneo, sin observarse lesiones asociadas. Fueron valoradas por el servicio de Neurocirugía, que indicó corrección quirúrgica de la lesión en ambos casos, con buena evolución posterior.


Spontaneous intrauterine depressed skull fractures are a rare entity. They can appear secondarily to head trauma (before or during birth) or due to unknown etiology. They usually require a complete evaluation from pediatric neurosurgery specialists. Their optimal management, including timely surgical treatment remains controversial. We describe two cases delivered by cesarean section, with postnatal diagnosis of spontaneous intrauterine depressed skull fracture. Both had a normal neurological exam. A skull radiography and head CT were performed, and no associated lesions were found. Both cases required surgical correction, with positive results.

ABSTRACT

Introducción: durante la pandemia por COVID-19, la radiografía portátil de tórax y la ultrasonografía se han usado ampliamente para el seguimiento de pacientes hospitalizados. Sin embargo, es escasa la información sobre la relación entre los signos que se observan mediante cada método en pacientes con COVID-19. Objetivo: estimar la correlación entre imágenes concurrentes obtenidas por ultrasonografía de pulmón y por radiografía portátil de tórax durante el seguimiento de pacientes hospitalizados por COVID-19. Material y métodos: se realizaron 113 estudios de ultrasonografía y los correspondientes 113 de radiografía portátil de tórax durante el seguimiento de 44 pacientes (30 hombres/14 mujeres, edad 30-85 años) con COVID-19 (RT-qPCR). Las imágenes se resguardaron en un sistema de comunicación para su evaluación independiente por dos especialistas en cada método. El análisis se hizo con correlación gamma y prueba t (significancia de 0.05). Resultados: el signo por ultrasonido más frecuente fue el de líneas B-confluentes en correlación con los signos radiológicos de imagen en vidrio deslustrado y consolidación. Se observó correlación inversa entre líneas A (pulmón aireado) y líneas B7 (sugerentes de edema intersticial); las líneas B-confluentes mostraron correlación inversa y fuerte con líneas A (a mayor frecuencia de líneas B-confluentes, menor frecuencia de líneas A), correlación inversa moderada con líneas B7 y correlación inversa débil con líneas B3. Conclusión: en el seguimiento de pacientes hospitalizados por COVID-19, los signos por ultrasonografía pulmonar y por radiografía portátil de tórax pueden ser complementarios para identificar las características del daño pulmonar


Background: During the COVID-19 pandemic, portable chest radiography (portable CRx) and lung ultrasonography (LUS) have been widely used to follow up hospitalized patients. Yet, it is scarce the information about the relation between the signs observed by means of each method in patients with COVID-19. Objective: To assess the correlation between concurrent images acquired by LUS and portable CRx during the follow-up of hospitalized patients with COVID-19. Material and methods: We performed 113 LUS and 113 corresponding CRx during the follow-up of 44 patients (30 men/14 women, 30-85 years old) with COVID-19 (RT-qPCR). Images were stored in a picture communication system and were revised by two specialists of each imaging method independently. Statistical analysis was performed using Gamma correlation and t test (significance level of 0.05). Results: The most frequent LUS sign was confluent B lines, and it was related to the most frequent portable CRx signs (ground-glass opacities and consolidations). An inverse relationship was observed between A lines (gas in the lungs) and B7 lines (suggestive of interstitial edema). Confluent B lines also showed a strong inverse correlation with A lines (more frequent confluent B lines were related to low frequent A lines), a moderate inverse correlation with B7 lines, and a mild inverse correlation with B3 lines. Conclusion: During the follow-up of hospitalized patients with COVID-19, LUS and portable CRx may complement each other to provide information about lung damage

ABSTRACT

Background: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and the subsequent global outbreak (coronavirus disease 2019 [COVID-19]) was declared a public health emergency in January 2020. Recent radiologic literature regarding COVID-19 has primarily focused on Computed Tomography (CT) chest findings, with chest radiography lacking in comparison. Objectives: To describe the demographic profile of adult patients with COVID-19 pneumonia requiring hospital admission. To describe and quantify the imaging spectrum on chest radiography using a severity index, and to correlate the severity of disease with prognosis. Method: Retrospective review of chest radiographs and laboratory records in patients admitted to a South African tertiary hospital with confirmed COVID-19 infection. The chest X-rays were systematically reviewed for several radiographic features, which were then quantified using the Brixia scoring system, and correlated to the patient's outcome. Results: A total of 175 patients (mean age: 53.34 years) admitted with COVID-19 were included. Ground glass opacification (98.9%), consolidation (86.3%), and pleural effusion (29.1%) was commonly found. Involvement of bilateral lung fields (96.6%) with no zonal predominance (61.7%), was most prevalent. Correlation between the Brixia score and outcome was found between severe disease and death (odds ratio [OR]: 12.86; 95% confidence interval [CI]: 1.58­104.61). Many patients had unknown TB (71.4%) and HIV (72.6%) statuses. Conclusion: In this study population, ground glass opacification, consolidation, and pleural effusions, with bilateral lung involvement and no zonal predominance were the most prevalent findings in proven COVID-19 infection. Quantification using the Brixia scoring system may assist with timeous assessment of disease severity in COVID-19 positive patients, as an overall predicator of clinical outcome.

ABSTRACT

Abstract Patients with implantable electric stimulation devices are challenging to the anesthesiologist since these cases demand a comprehensive knowledge about how the device operates, the indications for the implant and the implications that must be addressed during the perioperative period. This article is intended to provide the reader with clear and structured information so that the anesthesiologist will be able to safely deal with the situation of a patient with an implantable cardiac stimulation device, who has been programmed for emergent surgery. A search for the scientific evidence available was conducted in Pubmed / Medline, ScienceDirect, OVID, SciELO), for a non-systematic review. The incidence of the use of cardiac electric stimulation devices has been growing. Their operation is increasingly complex, and demands being constantly updated on the knowledge in the area.

ABSTRACT

Introducción: El recambio acetabular primario puede llegar a ser una intervención de gran complejidad en dependencia del defecto óseo existente. Las lesiones pueden ser segmentarias, cavitarias o combinadas. Este último patrón es el que se observa con mayor frecuencia en pérdidas óseas periprotésicas por aflojamiento aséptico. Objetivos: Mostrar la evolución de la cirugía de recambio en la artroplastia de cadera, y orientar al cirujano en la toma de decisiones de modo individualizado, para evitar las complicaciones. Método: Se realizó la investigación basada en el tema de estudio, mediante la revisión de libros de texto de la especialidad, artículos científicos publicados en diferentes bases de datos informáticas: Pubmed/MEDLINE, SciELO, BVS, Scopus, Ebsco, Google Scholar, Cochrane, así como otras consultas en bibliotecas médicas. Análisis de la información: Las prioridades en la planificación de la reconstrucción se establecen para proporcionar un implante estable, restaurar la masa ósea y optimizar la biomecánica de la cadera, aunque son los hallazgos intraoperatorios los que definitivamente indicarán el tipo de intervención a seguir. Las exigencias funcionales de los pacientes y las comorbilidades deben ser consideradas, así como el coste-efectividad de la reconstrucción planificada. Conclusiones: La artroplastia total de cadera ha demostrado mejorar significativamente la calidad de vida en pacientes, con una baja tasa de complicaciones. Para prevenir el aflojamiento aséptico es necesario ser cuidadosos en la técnica de colocación de los componentes protésicos y utilizar el tipo de material más adecuado a la edad, demanda funcional y reserva ósea de cada paciente(AU)


Introduction: Primary acetabular replacement can become a highly complex intervention depending on the existing bone defect. Lesions can be segmental, cavitary, or combined. This last pattern is the one most frequently observed in periprosthetic bone loss due to aseptic loosening. Objectives: To show the evolution of replacement surgery in hip arthroplasty, and to guide the surgeon in making individualized decisions, to avoid complications. Method: A research was carried out on the study topic, by reviewing specialty textbooks, scientific articles published in different databases such as Pubmed/ MEDLINE, SciELO, BVS, Scopus, Ebsco, Google Scholar, Cochrane, as well as other inquiries in medical libraries. Information analysis: Reconstruction planning priorities are established to provide a stable implant, restore bone mass, and optimize hip biomechanics, although it is the intraoperative findings that will definitely indicate the type of intervention to follow. The functional demands of the patients and the comorbidities must be considered, as well as the cost-effectiveness of the planned reconstruction. Conclusions: Total hip arthroplasty has been shown to significantly improve the quality of life in patients, with low rate of complications. To prevent aseptic loosening, it is necessary to be careful in the technique of placement of the prosthetic components and to use the type of material most appropriate to the age, functional demand and bone reserve of each patient(AU)

ABSTRACT

Abstract Objective The objective of the present work was to compare the measurement of acetabular component version on anteroposterior (AP) and on cross-table radiographs after total hip arthroplasty (THA). Methods Radiographs of 60 hips with a primary THA were selected. Version was calculated on the AP radiograph using the Lewinnek method and, on the cross-table, using the Woo and Morrey direct method. Results Mean and standard deviation (SD) were different on both radiographs, being 9.7° ± 5.5° on the AP, whereas in the cross-table the measurements were 20.6° ± 8.4° (p < 0.001). Minding our aim of 10°, the cross-table measurements were statistically different from it (p < 0.001), while the AP measurement did not differ (p = 0.716). Conclusion The present study showed that the best way to correctly evaluate the acetabular component positioning following a THA is by measuring anteversion and abduction on an AP radiograph after confirming, in a cross-table radiograph, that the component is not retroverted.


Resumo Objetivo O objetivo do presente trabalho foi comparar a medição da versão do componente acetabular em radiografias em incidência anteroposterior (AP) e crosstable após artroplastia total do quadril (ATQ). Métodos Foram selecionadas radiografias de 60 quadris com ATQ primário. A versão foi calculada na radiografia AP usando o método de Lewinnek e, na cross-table, usando o método direto do Woo e Morrey. Resultados A média e o desvio padrão (DP) foram diferentes em ambas as radiografias, sendo 9,7° ± 5,5° no AP, enquanto na cross-table foram 20,6° ± 8,4° (p < 0,001). Considerando nosso objetivo de 10°, as medidas da cross-table foram estatisticamente diferentes dele (p < 0,001), enquanto a medição AP não diferiu (p = 0,716). Conclusão O presente estudo mostrou que a melhor maneira de avaliar corretamente o posicionamento do componente acetabular após uma ATQ é medindo a anteversão e a abdução em uma radiografia AP após confirmar, em uma radiografia cross-table, que o componente não é retrovertido.

ABSTRACT

BACKGROUND: Computed tomography (CT) accounts for 13% of all radiological examinations in the United States and 40-70% of the radiation that patients receive. Even with the advent of magnetic resonance imaging (MRI), CT continues to be the gold standard for diagnosing bone fractures. There is uncertainty as to whether CT with a low radiation dose has a fracture detection rate similar to that of standard-dose CT. OBJECTIVE: To determine the detection rate of low-dose radiation CT and standard-dose radiation CT for fractures, in patients with suspected fractures. DESIGN AND SETTING: Systematic review of comparative studies on diagnostic accuracy within the evidence-based health program at a federal university in São Paulo (SP), Brazil. METHODS: We searched the electronic databases Cochrane Library, MEDLINE, EMBASE and LILACS up to June 29, 2020, for studies evaluating the detection rates of low-dose CT and standard-dose CT for diagnosing bone fractures. The Research Triangle Institute (RTI) item bank tool was used for methodological quality evaluation. RESULTS: The fracture detection rate according to the number of bones evaluated, using CT with low-dose radiation was 20.3%, while with standard-dose radiation it was 19.2%, and the difference between the methods was not significant. The fracture detection rate according to the number of patients, using CT with low-dose radiation was 56.0%, while with standard-dose radiation it was 58.7%, and this difference between the methods was not significant, either. CONCLUSION: CT with low-dose radiation presented detection rates similar to those of CT with standard-dose radiation, regardless of the bones evaluated.

ABSTRACT

La actual pandemia de COVID-19 ha afectado múltiples sectores económicos y sociales a escala mundial, con especial afectación sobre el sector de la salud, ya que constituye un reto adicional para la atención primaria, dada la marcada escasez de recursos. La infección por SARS-CoV-2 ocasiona morbilidad y mortalidad crecientes, por lo que el diagnóstico mediante imágenes es una herramienta imprescindible en la práctica clínica; sin embargo, el acceso limitado a algunos medios como la tomografía axial computarizada en diferentes niveles de atención, justifica el uso de la radiografía de tórax como una opción costo-efectiva y accesible en muchas regiones. En el presente artículo se exponen los hallazgos asociados a procesos infecciosos virales sugestivos de infección por el nuevo coronavirus y una serie de escalas de clasificación que buscan estandarizar la lectura e interpretación radiográfica por parte del personal médico.


The pandemic of COVID-19 has affected multiple economic and social sectors worldwide, with special effects on the health sector, since it constitutes an additional challenge for the primary health care, given the marked lack of resources. The infection due to SARS-CoV-2 causes increasing morbidity and mortality, reason why the diagnosis by means of images is an indispensable tool in the clinical practice; however, the limited access to some means as the computerized axial tomography in different levels of care, justifies the use of the thorax x-ray as a cost-effective and accessible option in many regions. Findings associated with suggestive viral infectious processes of infection due to the new coronavirus and a series of classification scales that seek to standardize reading and radiographic interpretation by the medical staff are exposed in this work.

ABSTRACT

ABSTRACT Objective: To determine the preoperative radiographic method for measuring the Cobb angle that is closest to the postoperative result in patients with scoliotic deformity. Methods: Retrospective cohort study of radiographic spinal evaluation (preoperative posteroanterior (PA), bending, traction, traction under anesthesia and immediate postoperative posteroanterior (PO)) of 26 patients treated surgically for scoliotic deformities during the period from January 2017 to September 2019. The final mean Cobb angle and its decrease in relation to the PA value were evaluated in the three curves in patients with idiopathic (IS) and non-idiopathic scoliosis. Results: All the mean curve values were statistically significant, except for bending in non-idiopathic scoliosis (non-IS). The mean traction under anesthesia values were closer to the PO values. Regarding the delta (decrease) of the maneuvers in relation to the PA, no statistical significance was observed in the non-IS group. The traction under anesthesia maneuver had a greater delta in all curves. Conclusions: The traction under anesthesia maneuver in patients with idiopathic scoliosis is the method with the greatest flexibility and which best predicts the postoperative result. Level of evidence III; Diagnostic study.


RESUMO Objetivo: Objetivo: Determinar o método radiográfico pré-operatório para aferição do ângulo de Cobb que mais se aproxima dos resultados pós-operatórios em pacientes com deformidade escoliótica. Métodos: Estudo de coorte retrospectivo de avaliação radiográfica da coluna vertebral (posteroanterior pré-operatória [PA], inclinações, tração, tração com anestesia e posteroanterior pós-operatória imediata [PO]) de 26 pacientes com deformidades escolióticas no período de Janeiro de 2017 a Setembro de 2019 tratados com cirurgia . Avaliou-se a média final do ângulo de Cobb e a sua diminuição com relação ao PA nas três curvas em pacientes com escoliose idiopática (EI) e não idiopática. Resultados: Todas as médias das curvas têm significância estatística, exceto a inclinação na escoliose não idiopática (não EI). A tração com anestesia apresenta média de valores mais próximos ao PO. Com relação ao delta (diminuição) das manobras referentes ao PA, foi observado que não houve significância estatística nas não EI. A manobra de tração com anestesia tem delta maior em todas as curvas. Conclusões: A manobra de tração com anestesia em pacientes com escoliose idiopática configura-se como o método com maior flexibilidade e que melhor prediz o resultado pós-operatório. Nível de evidência III; Estudo diagnóstico.

ABSTRACT

Introdução: em 1875, Hamilton identificou o formato do acrômio como uma etiologia de dor no ombro. Neer, em 1972, descreveu a síndrome do impacto no ombro como uma relação de causa e efeito entre a morfologia do acrômio e o impacto subacromial. Em 1986, Bigliani et al. apresentaram um esquema de classificação do acrômio de acordo com o formato de sua superfície inferior: plano (tipo I), curvo (tipo II) e gancho (tipo III). Em 1993, Epstein et al. proporam que o acrômio tipo II apresentaria um declive em seu terço médio e o tipo III no seu terço anterior. Objetivo: avaliar a reprodutibilidade/confiabilidade interavaliador do método de Bigliani et al. (1986) refinado por Espstein et al. (1993) para a classificação do tipo acromial. Metodologia: casuística composta por 20 voluntários brasileiros, de ambos os gêneros, entre 21-25 anos. A incidência radiográfica utilizada para visualizar o formato do acrômio foi perfil de escápula. O tipo acromial foi classificado por três avaliadores. A reprodutibilidade e confiabilidade foram avaliadas pelo teste McNemar e pelo índice Kappa. Resultados: teste de McNemar com p > 0,05; índice Kappa entre 0,61 e 0,8; e probabilidade de significância p de Kappa < 0,05 confirmam a muito boa reprodutibilidade e confiabilidade do método para classificação do tipo acromial entre os três avaliadores. Conclusão: o método de Bigliani et al. (1986) refinado por Epstein et al. (1993) para classificação do tipo acromial mostrou concordância entre todos os avaliadores confirmando a muito boa reprodutibilidade e confiabilidade entre os avaliadores do estudo.


Introduction: in 1875, Hamilton identified that acromion shape was an etiology for shoulder pain. In 1972, Neer described shoulder impact syndrome as a cause and effect relationship between acromion morphology and subacromial impact. In 1986, Bigliani et al. presented an acromion classification scheme according to the shape of its lower surface: flat (type I), curved (type II) and hook (type III). In 1993, Epstein et al. proposed that the type II acromion would have a slope in its middle third and type III in its anterior third. Objective: to evaluate the inter-rater reproducibility and reliability of the method of Bigliani et al. (1986) for classifying acromial type, as refined by Epstein et al. (1993). Methodology: this was a case series composed of 20 Brazilian volunteers of both genders, aged 21-25 years. The shape of the acromion was visualized radiographically using the supraspinatus outlet view. Acromial type was classified by three evaluators. Reproducibility and reliability were assessed using the McNemar test and kappa index. Results: the McNemar test showed probability p > 0.05 and the kappa index was between 0.61 and 0.8 significant result: p < 0.05. These confirmed that this method had very good reproducibility and reliability for classifying acromial type among the three evaluators. Conclusion: the method of Bigliani et al. (1986) for classifying acromial type, as refined by Epstein et al. (1993) showed agreement among all the evaluators. This confirmed that there was very good reproducibility and reliability among the evaluators of this study.

ABSTRACT

This study aimed to evaluate the effectiveness of bridge plating of simple tibial fractures in dogs by minimally invasive plate osteosynthesis (MIPO). Medical and radiographic records of twenty-nine dogs with simple tibial fractures that underwent bridge fixation by MIPO were retrospectively evaluated. The clinical outcome was classified considering the presence of lameness at the end of the treatment. The tibial mechanical joint angles were measured and compared with the values described in the literature. Additionally, fragment apposition and implant disposition were evaluated. Based on the modified Radiographic Union Scale for Tibial fractures, the moment of clinical union was determined. Clinically, at the end of treatment, only one patient presented lameness at a trot. While there was no significant difference between the bone alignment in the frontal plane values and the values described in the literature (P>0.05), the caudal proximal tibial angle was significantly higher (P=0.001). The median fragment apposition was considered acceptable. The average bridge plate ratio, plate working length, and plate screw density were 0.8, 0.57, and 0.48, respectively. The median time to clinical union was 30 days. Bridge plating in simple tibial fractures resulted in fast healing and low complication rates.(AU)


Objetivou-se avaliar a efetividade da estabilização em ponte de fraturas tibiais simples em cães utilizando-se a técnica de osteossíntese minimamente invasiva com placa (MIPO). Registros médicos e radiográficos de 29 cães com fraturas simples de tíbia, fixadas em ponte por meio da MIPO, foram retrospectivamente avaliados. O resultado clínico foi classificado com base na deambulação ao final do tratamento. Os ângulos articulares mecânicos da tíbia foram aferidos e comparados aos valores descritos na literatura. Adicionalmente, foram avaliadas a aposição dos fragmentos e a disposição dos implantes. Por meio da escala modificada de união radiográfica para fraturas de tíbia, determinou-se o momento de união clínica. Clinicamente, ao final do tratamento, apenas um animal apresentou claudicação ao trote. Não houve diferença significativa entre o alinhamento ósseo no plano frontal quando comparado com dados da literatura (P>0,05), enquanto, no plano sagital, o ângulo mecânico caudal proximal da tíbia foi significativamente maior (P=0,001). A mediana para aposição dos fragmentos foi considerada aceitável. As médias para relação placa em ponte, comprimento de trabalho da placa e densidade de parafusos da placa foram, respectivamente, 0,8; 0,57 e 0,48. A mediana para união clínica foi de 30 dias. A estabilização em ponte de fraturas tibiais simples resultou em rápida consolidação óssea, com baixas taxas de complicação.(AU)

ABSTRACT

Resumen El vólvulo gástrico es una entidad rara que puede presentarse de manera aguda o crónica y se acompaña de síntomas inespecíficos. Es fundamental su rápida identificación, ya que tiene alta mortalidad y el tratamiento oportuno de esta patología determina el pronóstico del paciente. A continuación, presentamos el caso de una paciente femenina de 89 años, que consulta por cuadro clínico de dolor torácico atípico, con documentación en radiografía de tórax de vólvulo gástrico organoaxial, en quien se realiza inicialmente devolvulación endoscópica con éxito. Sin embargo, en las imágenes de control se evidencia recurrencia del vólvulo, por lo cual se realizó manejo quirúrgico con hiatoplastia y funduplicatura tipo Toupet, además de gastrostomía percutánea de fijación, procedimiento realizado sin complicaciones, con los que se logró la devolvulación completa sin recurrencia.


Abstract Gastric volvulus is a rare condition that can occur acutely or chronically and is accompanied by nonspecific symptoms. Its rapid identification is critical since it has high mortality rate and timely treatment determines the patient's prognosis. The following is the case of an 89-year-old female patient who presented with atypical chest pain, with organoaxial gastric volvulus on chest X-ray, in whom endoscopic devolvulation was initially performed successfully. However, control imaging scans revealed recurrence. Therefore, surgical management included hiatoplasty and Toupet fundoplication, as well as percutaneous fixation gastrostomy, a procedure that was completed without complications and resulted in complete devolvulation without recurrence.

ABSTRACT

Introducción: los estudios por imágenes (EPI) son de gran ayuda para el diagnóstico clínico, pero su uso irracional puede ocasionar daños. Objetivos: relevar las percepciones y expectativas sobre estudios por imágenes pediátricos en un grupo de padres de niños sanos. Evaluar los datos obtenidos en relación con el registro de EPI solicitados por Guardia durante el mismo período. Materiales y métodos: estudio exploratorio, descriptivo, cuali-cuantitativo mediante una encuesta en una muestra por conveniencia en un centro pediátrico ambulatorio, a lo largo de dos meses. Análisis retrospectivo de solicitud de EPI en el registro informatizado de historias clínicas de Guardia durante el mismo período. Resultados: respondieron 243 padres. El 93,4% refirió conocer métodos de EPI (la radiografía[Rx] fue el más conocido). Se había realizado al menos un EPI al 83,4% de los niños en los últimos doce meses. El estudio fue explicado en forma clara en el 96,4% de los casos. Un 47,7% de los padres refirieron conocer las consecuencias del uso repetitivo de EPI. El 81,6% acordó con que "ante cualquier traumatismo se debe realizar Rx para descartar fractura". Más del 60% consideró que debe realizarse Rx de tórax a todo niño con tos sin fiebre o con fiebre de más de dos días y 55% solicitarían Rx de senos paranasales si el niño elimina mocos verdes. El 49,8% opinó que los médicos piden EPI de menos (por falta de recursos, para trabajar menos o para ahorrar dinero). Durante el período estudiado se solicitó una radiografía al 5% de los pacientes que consultaron por Guardia; no se encontró justificación para solicitar el estudio en el 29% de los casos. Conclusión: un gran porcentaje de padres conoce los EPI; sin embargo, desconocen los riesgos asociados a su uso. Existen errores de concepto que generan expectativas desmedidas con respecto a la indicación de Rx. Se informó un exceso en las solicitudes de EPI por Guardia. Los padres consideran que los médicos solicitan EPI de menos. (AU)


Introduction: ediatric radiologic exams (PRE) are of great value for clinicians. It's over or misuse can lead to irreparable damage that can be prevented. Objective: to describe perceptions and expectations for the use of PRE among healthy children`s parents in an ambulatory center. To analyze these results in relation to the report of PRE performed in the emergency room during the same period. Methods: observational, cross sectional, quali- quantitative study using a survey on a convenience sample conducted in an outpatient pediatric center over a two months period. Retrospective analysis of medical records to evaluate PRE requested on the ER during the 2 months of the study. Results: 243 parents completed the survey. 93,4% were familiar with PRE (X-rays being the most popular among them). 83,4% of children in our sample had at least one PRE in the past 12 months. The need and utility of the study had been explained to the parents clearly in 96,4% of cases. 47,7% of parents knew about the side effects associated with repetitive use of PRE. 81,6% agreed with the statement "in the event that a child should suffer any trauma, an X-Ray should be performed to look for fractures". Over 60% think a chest X ray has to be obtained if the child has fever for over 48 hours and 55% would expect an X ray to be performed whenever a child has green nasal discharge. 49,8% respondents think that doctors order less than necessary (for lack of resources, unwillingness to work in or to save money). The analysis of clinical reports showed that X-Rays were performed to 5% of children at the emergency clinic. Among them, we found no reason for the study in 29% of the cases. Conclusion: we found that parents were very familiar with PRE, however less than half our sample knew of the potential risks related to their use. There are considerable misconceptions among parents regarding X-Ray use. Parents considered that doctors order too little PRE. (AU)
