Fat embolism syndrome in a patient with a right undisplaced femoral neck fracture.

Fat embolism syndrome (FES) is a rare condition characterised by the classic triad of respiratory distress, neurologic symptoms and petechial rash. Here, we encountered a case of FES in a patient with an asymptomatic right undisplaced femoral neck fracture (Garden Stage II). FES was diagnosed based on the Gurd and Willson's diagnostic criteria and brain magnetic resonance imaging features. To the best of our knowledge, this is the first case of FES in a patient with an undisplaced femoral neck fracture. This study highlights the importance of considering the possibility of FES even in patients with undisplaced femoral neck fractures.

Association of socioeconomic factors and the risk for unintentional injuries among children in Japan: a cross-sectional study.

OBJECTIVES: While Japan has socioeconomic issues, such as income inequality, little is known about the association between socioeconomic factors and the risk of unintentional childhood injuries. The purpose of the study was to evaluate the influence of socioeconomic factors on the risk for unintentional injuries among preschool children in Japan. DESIGN: Cross-sectional study using data from a web-based questionnaire survey. SETTING: Japan (January 2015). PARTICIPANTS: 1000 households with preschool children under 6 years of age. OUTCOME MEASURES: Multivariate logistic regression was performed to analyse the influence of socioeconomic factors on the incidence of unintentional injuries. RESULTS: Overall, 976 households were eligible for the analysis, with 201 households reporting unintentional injuries. The incidence rates for unintentional injury were estimated to be constant across all strata constructed using combinations of socioeconomic factors. The multivariate logistic regression analysis showed no significant differences in socioeconomic factors between households that reported unintentional injuries and those that did not. CONCLUSION: The findings of our study demonstrated that unintentional injuries among preschool children occurred at approximately fixed rates, independent of socioeconomic factors. Accordingly, prevention strategies for unintentional injuries that concern socioeconomic disadvantages should be avoided in Japan.
