Sociodemographic factors influence the risk for femur shaft fractures in children: a Swedish case-control study, 1997-2005

ObjectivesThis study aimed to investigate the association between sociodemographic factors and residential fire fatalities in Sweden. A majority of fatal fires occur in housing. An understanding of risk factors and risk groups is a must for well-founded decisions regarding targeted prevention efforts. There is a lack of consideration of the interrelation between sociodemographic factors and fire fatalities and there is a lack of high quality large-scale studies.MethodsIn this matched case-control study, residential fire fatalities (cases, n=850) (age above 19 years old) were identified in the national register on fatal fires. Four controls per case were randomly matched by gender and age. ORs were calculated to assess the association between different sociodemographic factors with residential fire fatalities using conditional logistic regression.ResultsHaving low income, receiving social allowance and receiving health-related early retirement pension were associated with an increased risk of dying in residential fires. The results also show clearly that adults dying in residential fires to a significantly lower extent were living together with a partner, were in work, were highly educated and lived in urban areas. However, contrary to previous research, living in rented apartments appeared not to influence the risk of death.ConclusionsIn this study, we show that fatalities due to residential fires in Sweden are associated with some but not all of previously published sociodemographic risk factors. The results provide valuable information that can improve the guiding and targeting of fire mortality prevention strategies in Sweden.

Femur Shaft Fractures

Introduction:Complex femur fractures are defined as combined fractures of shaft and proximal of or the distal femur. Restoration of anatomical alignment is the primary goal of the management of these fractures. In this report, we describe the management of complex femur shaft fractures in three pediatric patients. Case Report: This report includes three patients. The first patient was a 10-year-boy with comminuted proximal femur shaft fracture extending into the subtrochanteric area, managed with minimally invasive sub-muscular plating. The second patient was a 12-year-boy with comminuted femur shaft extending into subtrochanteric area, treated with combined retrograde and anterograde Titanium Elastic Nail System. A 12-year-old boy with femur shaft with intertrochanteric fracture managed with K-wire fixation for intertrochanteric fracture and plating with dynamic compression plate for femur shaft was our third patient. All patients had excellent radiological and functional outcome. Conclusion: Complex femur shaft fractures in children are very rare and challenging injuries. With proper pre-operative planning and use of appropriate implants excellent outcomes can be obtained. Keywords:Complex femur fractures, pediatric orthopedics, sub-muscular plating, titanium elastic nailing.

Control Study

In the last few years a role of Lupus Anticoagulant (LAC) in the aetiology of repeated spontaneous abortions and intrauterine deaths has been repeatedly suggested. To quantify this association few da ta are available, since the published reports are generally based on uncontrolled and small clinical series. We have analyzed data from a case-control study conducted in Bergamo and Milan, two contiguous provinces in Lombardia, Italy. Cases were 63 women, mean age 30 years, range 23-40, with 2 or more "sine causa" spontaneous abortions (repeated abortions) admitted between March 1985 and December 1986 to the Ospedali Riuniti of Bergamo and Istituti Clinici di Perfezionamento of Milan. Controls were 63 women, mean age 32 years, range 20-49, with 1 or more live births and without spon taneous abortions, admitted to the same Institutions for neither gynaecological nor cardiovascular acute conditions. Informations were collected on sociodemographic factors, gynaecological and obstetrical data and related medical history. LAC was diagnosed according to the Working Party reccomandations (1983) and Systemic Lupus Erythematosus (SLE) according to the revised criteria of ihe American Rheumatism Association (1982). 11 out of 63 cases (17%) (95% confidence interval ranging from 9.5% to 34% based on the Poisson's approximation) were LAC positive, whereas in none of 63 controls this inhibitor was detected (X2 1adjusted for age = 10.1, p= 0.02). Similarly SLE was diagnosed in 4 cases (all having a Lupus Anticoagulant) and in none control (x2 1adjusted for age= 4.17, p=0.02). These findings confirm that LAC is associated with a positive history of repeated abortions, being present in about 10% of the cases. Conclusive estimate of relative risk is prevented by the small control gr'oup size (i.e. lack of positivity for LAC in controls), but very elevated risk (many tenfold increase) is sugge. sted.
