Cement Embolization into the Vena Cava and Pulmonal Arteries After Vertebroplasty: Interdisciplinary Management

AbstractPurposeTo report interdisciplinary management in a case of cement embolization into the inferior vena cava and peripheral pulmonary arteries after percutaneous vertebroplasty.Case reportA 50-year-old female patient with an osteoporotic compression fracture of the second lumbar vertebra underwent percutaneous vertebroplasty with polymethylmetaacrylate. Thereafter, CT scanning revealed small asymptomatic cement emboli in peripheral pulmonary arteries, along with a hook-shaped cement fragment in the inferior vena cava. Due to the risk that the large cement fragment could migrate to the pulmonary arteries and cause serious complications, they were retrieved from the inferior vena cava by an endovascular technique and extracted through a surgical groin incision. The patient received anticoagulant treatment for 3 months and is free of complaints after 1 year.ConclusionThis case shows that this rare complication following vertebroplasty can be successfully managed with an interdisciplinary approach

Remanent Magnetic Measurements on Perpendicular Recording Materials with Compensation for Demagnetizing Fields

Existing techniques for characterization of longitudinal recording media using remanence measurements are extended to perpendicular media, in particular to Alumite, and correction for demagnetizing fields is taken into account. It is found that these techniques have limited value because of the sensitivity of the analysis to the correction factor used. Measurement of the recoil lines is investigated as an alternative method of probing the reversal processes

Book review: Gerald D. Feldman, Austrian banks in the period of National Socialism

Even though Germany, Austria, and Hungary experienced a major financial crisis simultaneously in 1931, of the three, only Germany's and Austria's episodes have been investigated in depth. This article offers a thorough assessment of the missing piece. It finds that, just like Germany, Hungary also experienced a twin crisis. The primary reason for the weakness of the financial sector was banks’ excessive exposure to agricultural loans. The fragility of the currency was the result of an early balance-of-payments crisis in 1928/9. The vulnerability of the banking and monetary systems culminated in a twin crisis in 1931

Citizenship Norms in Eastern Europe

Research on Eastern Europe stresses the weakness of its civil society and the lack of political and social involvement, neglecting the question: What do people themselves think it means to be a good citizen? This study looks at citizens’ definitions of good citizenship in Poland, Slovenia, the Czech Republic and Hungary, using 2002 European Social Survey data. We investigate mean levels of civic mindedness in these countries and perform regression analyses to investigate whether factors traditionally associated with civic and political participation are also correlated with citizenship norms across Eastern Europe. We show that mean levels of civic mindedness differ significantly across the four Eastern European countries. We find some support for theories on civic and political participation when explaining norms of citizenship, but also demonstrate that individual-level characteristics are differently related to citizenship norms across the countries of our study. Hence, our findings show that Eastern Europe is not a monolithic and homogeneous bloc, underscoring the importance of taking the specificities of countries into account
