This study aims to perform the first molecular and clinical-epidemiological analysis of dengue cases in Divinopolis, MG, Brazil. Data from 4,110 cases of dengue were accessed and 190 clinical samples were collected for molecular analyses. In this study, 2.7% of the men and 3.0% of the women were admitted to hospital. There was no association between gender and hospital admission. The symptoms observed in this study are according to the Health Ministry, but fever was present in 82.2% and not in 100% of cases. The chance of hospital admission was 1.55 higher in patients with any kind of bleeding (334) and 2.4% of individuals without bleeding were also hospitalized due to other warning signs. In the molecular analyses, 23% of the samples were positive for DENV. DENV-2 and DENV-3 were identified in 2010, DENV-3 in 2011, DENV-1 in 2012, and DENV-1 and DENV-4 in 2013. DENV detection was possible in samples with only one day of symptoms. This first report of dengue data in Divinópolis provided more insight into the viral types and effects of disease in the city, confirming the need for caution in assessing cases of suspected dengue and for revision of the criteria proposed by the Health Ministry to classify cases of the disease.

The accurate diagnosis of pulmonary thromboembolism is essential to reducing the morbidity and mortality associated with the disease. The diagnosis of pulmonary thromboembolism is challenging because of the nonspecific nature of the clinical profile and the risk factors. Imaging methods provide the definitive diagnosis. Currently, the imaging method most commonly used in the evaluation of pulmonary thromboembolism is computed tomography. The recent development of dual-energy computed tomography has provided a promising tool for the evaluation of pulmonary perfusion through iodine mapping. In this article, we will review the importance of diagnosing pulmonary thromboembolism, as well as the imaging methods employed, primarily dual-energy computed tomography.

O câncer de próstata é um dos mais prevalentes no sexo masculino, sobretudo, em pacientes idosos. A ressonância magnética (RM), é uma ferramenta de diagnóstico por imagem que evoluiu muito nos últimos anos, principalmente com o advento da avaliação multiparamétrica através das sequências ponderadas em T2, Difusão e Perfusão. O objetivo deste estudo, foi avaliar o papel da Ressonância Magnética Multiparamétrica (RMMP) na caracterização do câncer de próstata (CaP) em pacientes no programa de vigilância ativa, no estadiamento pré-terapêutico e na detecção de recidiva bioquímica. Trata-se de um estudo analítico, retrospectivo de pacientes com diagnóstico de CaP, submetidos ao exame de RMMP realizados entre os anos de 2014 e 2019 no Departamento de Imagem do A.C.Camargo Cancer Center. 203 relatórios revisados foram incluídos na análise. Destes resultados, 82 estavam em programa de vigilância ativa, 67 recidiva bioquímica e 54 estadiamento. Na Vigilância ativa a classificação PI-RADS 2 foi a mais frequente. Houve estabilidade no EG posterior em relação ao anterior. Na recidiva bioquímica houve aumento no EG posterior em relação ao anterior. A principal conduta adotada foi manter o acompanhamento. No estadiamento a classificação PI-RADS 2 foi a mais frequente. Houve aumento no EG posterior em relação ao anterior. Não ocorreram casos de mortalidade durante o período analisado.

Objective: In the present article, we will describe the indications for chest MRI in patients diagnosed with malignancy and its relevant role in distinguishing benign from malignant lesions and in detecting metastases.  Materials and methods: Single-center, retrospective, analytical imaging and chart-review study of all patients with a diagnosis of cancer who underwent chest MRI at the Imaging Department of A.C. Camargo Cancer Center from January 2014 through December 2016. Information was collected through an electronic questionnaire and exported to a Microsoft Excel spreadsheet. Data were then processed in Action Stat 3 software. Descriptive analysis was conducted with conventional measures of central tendency (mean, median, mode) and dispersion (range, variance, standard deviation, and coefficient of variation), as well as calculation of absolute and relative frequencies. Results: The leading indication for chest MRI was post-treatment follow-up. Chest MRI was most often requested by the Departments of Thoracic Surgery and Clinical Oncology. In most cases, the results of chest MRI led to maintenance of the current treatment plan rather than a change in management. Conclusion: Magnetic resonance imaging has several applications in evaluation of the chest, and can be used by various specialties and subspecialties. In the present study, post-treatment follow-up and maintenance of current therapy were the most common indication and management, respectively.
