Summary: This was a retrospective observational study to determine the secular trends in osteoporosis hip fractures in Brazil from 2004 to 2013. The fracture rates were stable for both sexes, and there was not a secular trend. Fractures were predominant in the South and Southeast Regions. The hip fracture rate was lower in this study than in other studies. These regional differences may be considered in the FRAX Brazil calibration. Purpose: Hip fractures are well-known osteoporotic fractures with high mortality and morbidity. Epidemiological studies in Brazil on hip fractures are scarce, and the great majority have been performed in small populations from a few cities. None of these studies has analyzed the long-term hip fracture secular trends, which are important data for the promotion of public health actions. Methods: This was a retrospective observational study with a secular trend analysis in patients over 50 years old who were admitted to the Brazilian Public Health System from 2004 to 2013. We collected hospitalization data according to the ICD-10 for low-trauma hip fractures. The fracture rate was calculated when the patients were stratified by sex, age, and geographic region, and linear regression analysis was performed to evaluate the secular trends. Results: The hip fracture rate per 100,000 inhabitants was 59.69; the rate was 74.72 in females and 42.95 in males. The fracture rates were higher in the South and Southeast Regions and steadily increased with age, and the average ratio of women-to-men was 1.74. No secular trend was detected in the overall population. Surprisingly, the secular trend only increased in the South region from 2004 to 2013, and the secular trends were stable in the other regions. Conclusion: Although the secular trend was similar to some worldwide studies, the hip fracture rate was lower than that previously observed in regional studies in Brazil. These regional differences may be considered in the FRAX Brazil calibration. [ABSTRACT FROM AUTHOR]

The article presents a case study of a 44-year-old male patient with a bulge in the hemithoraxic region of the thoracic wall. The opacification of the hemithorax was observed through the chest x-ray that corresponded to the heterogeneous mass during the CT scan of the patient. Information on the observation of the proliferative lesion with the fusocellular areas through the transparietal biopsy of the mass is also presented.
