ABSTRACT
OBJECTIVE: Prostate cancer has a high prevalence and mortality, being the most diagnosed urologic cancer. Prostatic magnetic resonance imaging showed high sensitivity in the detection of clinically significant neoplasia and agreement with the Gleason score. Therefore, we attempted to evaluate the diagnostic accuracy of the prostate imaging reporting and data system, using biopsy and prostatectomy as the reference standard. The secondary goal of correlating prostatic magnetic resonance imaging findings and anatomopathological samples is obtained. MATERIALS AND METHODS: We retrospectively analyzed seventy-nine 1.5 Tesla prostatic magnetic resonance imaging scans in patients aged 31 to 86 years, performed at the Clinical Hospital of the Federal University of Paraná between January 2015 and February 2018. RESULTS: Considering all 79 patients, prostatic magnetic resonance imaging was able to diagnose tumor in 47 patients (59.4%). Considering the peripheral zone, the prostatic magnetic resonance imaging had a sensitivity of 75.0% (95% confidence interval: 52.1%-98.0%), specificity of 89.5% (95% confidence interval: 66.0%-100%), 94.4% positive predictive value (95% confidence interval: 71.0%-100%), 66.7% negative predictive value (95% confidence interval: 43.0%-69.0%), 83.8% Positive Likelihood Ratio (PVR) (95% confidence interval: 60.0%-100%), 27.9% Negative Likelihood Ratio (RVN) (95% confidence interval: 5.0%-50.0 %), and accuracy of 86.3% (95% confidence interval: 63.0%-100%). The receiver operating characteristic curve obtained demonstrated the sensitivity variation according to the prostate imaging reporting and data system score of the patients, obtaining an area under the curve of 84.8 for a prostate imaging reporting and data system cutoff of 3. CONCLUSION: The use of the prostate imaging reporting and data system score is useful for the screening and classification of prostate cancer, due to its easy reproducibility, even in a population with an unknown prostate cancer prevalence, which can be easily correlated with biopsy studies and/or radical prostatectomy.

Objetivo: Verificar a prevalência da concomitância de fraturas diafisárias e metafisárias do fêmur em pacientes, vítimas de acidente por motocicleta, atendidos no pronto socorro de Curitiba/PR em um período de sete anos e comparar os resultados com os dados presentes na literatura nacional.Metodologia: Realizou-se um estudo descritivo, retrospectivo e observacional da prevalência de fraturas de diáfise do fêmur concomitantemente à metáfise proximal ou metáfise distal do fêmur ipsilateral. Os dados foram obtidos através da análise de todos os prontuários do período de janeiro de 2007 a dezembro de 2013 catalogados no arquivo médico do HUEC. Considerou-se para análise o número de vítimas, sexo, idade e lado da fratura. Resultados: Foram identificados 40 pacientes: 87,5% do sexo masculino e 12,5% do sexo feminino. Houve predomínio de pacientes entre 19 e 29 anos. A média de idade foi de 31,9 anos. 24 vítimas foram diagnosticadas com fratura de diáfise do fêmur associada à fratura de metáfise proximal ipsilateral, sendo 16 do lado esquerdo e 8 a direita. 16vítimas foram diagnosticadas com fratura de diáfise do fêmur associada à fratura de metáfise distal ipsilateral, sendo 8 do lado direito e 8 a esquerda. Conclusão:O perfil de vítima mais prevalente foi o de adulto jovem do sexo masculino e a associação mais encontrada foi a de fratura da diáfise do fêmur concomitante à fratura da metáfise proximal do fêmur ipsilateral à esquerda
Objective: Verify the prevalence of concomitance between diaphysis and metaphysis femur fractures in patients, victims of motorcycle accidents, seen at the Emergency Departmentof Hospital Universitário Evangélico de Curitiba (HUEC), in a period of sevenyears, as well as compare the results with data from literature. Material and Methods:This is a retrospective, descriptive, observational study of prevalence of diaphysis femur fractures simultaneously with ipsilateral proximal metaphysisordistal metaphysis femur fractures. The information was obtainedfrom the analysis of all the medical records from January 2007 to December 2013 belonging to the hospital archives. The analysis considered the number of victims, gender, age and affected side.Results:40 victims have been identified. 87.5% being male whereas 12.5% being female. The victims were predominantly between 19 and 29 years old. The average age of thevictims was 31.9 years old. 24 victims were diagnosed with diaphysis femur fracture associated with ipsilateral proximal metaphysis, 16 were on the left and 8 were on the right. 16 victims were diagnosed with diaphysis femur fracture associated with ipsilateral distal metaphysis, 8 were on the right and 8 were on the left. Conclusion: The most prevalent victim profile was that of a young adult male and the most frequent association was the concomitant fracture of femur fracture of the proximal metaphysis of the ipsilateral femur left
ABSTRACT
OBJECTIVE: Show the epidemiological profile of limb fractures in victim of motorcycle accident seen at the Emergency Department of Hospital Universitário Evangélico de Curitiba (HUEC), Curitiba, PR, Brazil, from January 2007 to December 2013, as well as to compare the results with data from the literature. METHODS: This is a retrospective, descriptive, observational study. The information was obtained from the analysis of all the medical records from January 2007 to December 2013 belonging to the hospital archives. Only extremity fractures cases from motorcycle accident victims were analyzed, according to the medical records and radiological reports. The ICD-10 was used as classification criterion, and the fractures were grouped depending on the topography of the injury. The following variables were considered: number of victims, gender, age and fracture site, in order to create a database to contrast with the literature. RESULTS: During seven years, 3,528 motorcycle accident victims have been identified, 88.29% being male, whereas 11.71% being female. The average age of the victims was 29.7 years old, observing a strong inverse correlation between the number of victims and their ages. There has been 4,365 fractures, being 59.66% in lower limbs and 40.34% in upper limbs. From that total, 18.14% were leg fractures, 11.57% were hand fractures and 10.65% were wrist fractures. CONCLUSION: This study has met its objectives and the results were similar to the national literature. Level of Evidence II, Retropective Study.
