Children account for an appreciable proportion of total imported malaria cases, yet few studies have quantified these cases, identified trends, or suggested evidence-based prevention strategies for this group of travelers. We therefore sought to identify numbers of cases and deaths, Plasmodium species, place of malaria acquisition, preventive measures used, and national origin of malaria in children. We analyzed retrospective data from Australia, Denmark, France, Germany, Italy, Japan, the Netherlands, Sweden, Switzerland, the United Kingdom, and the United States and data provided by the United Nations World Tourism Organization. During 1992-2002, >17,000 cases of imported malaria in children were reported in 11 countries where malaria is not endemic; most (>70%) had been acquired in Africa. Returning to country of origin to visit friends and relatives was a risk factor. Malaria prevention for children should be a responsibility of healthcare providers and should be subsidized for low-income travelers to high-risk areas.

BACKGROUND Brain abscesses caused by Nocardia spp. are rare, but life-threatening infections that are notoriously difficult to diagnose and treat and which occur mainly in immunocompromised patients. Standard treatment guidelines are not available. METHODS A systematic search for nocardial brain abscesses from 1992 to 1999 was conducted in Switzerland for the comparison of clinical presentation, treatment strategies and outcome. RESULTS Seven cases were found, for which data of six were available. In 4/6 patients antimicrobial therapy led to a decrease in the size of abscesses. Four of six patients died. The cause of death was likely due to underlying co-morbidities, rather than the nocardial infection. CONCLUSION The finding that treatment was different in each case underscores the lack of therapeutic guidelines.

BACKGROUND Rising levels of overweight and obesity are important public-health concerns worldwide. The purpose of this study is to elucidate their prevalence and trends in Switzerland by analyzing variations in Body Mass Index (BMI) of Swiss conscripts. METHODS The conscription records were provided by the Swiss Army. This study focussed on conscripts 18.5-20.5 years of age from the seven one-year birth cohorts spanning the period 1986-1992. BMI across professional status, area-based socioeconomic position (abSEP), urbanicity and regions was analyzed. Two piecewise quantile regression models with linear splines for three birth-cohort groups were used to examine the association of median BMI with explanatory variables and to determine the extent to which BMI has varied over time. RESULTS The study population consisted of 188,537 individuals. Median BMI was 22.51 kg/m2 (22.45-22.57 95% confidence interval (CI)). BMI was lower among conscripts of high professional status (-0.46 kg/m2; 95% CI: -0.50, -0.42, compared with low), living in areas of high abSEP (-0.11 kg/m2; 95% CI: -0.16, -0.07 compared to medium) and from urban communities (-0.07 kg/m2; 95% CI: -0.11, -0.03, compared with peri-urban). Comparing with Midland, median BMI was highest in the North-West (0.25 kg/m2; 95% CI: 0.19-0.30) and Central regions (0.11 kg/m2; 95% CI: 0.05-0.16) and lowest in the East (-0.19 kg/m2; 95% CI: -0.24, -0.14) and Lake Geneva regions (-0.15 kg/m2; 95% CI: -0.20, -0.09). Trajectories of regional BMI growth varied across birth cohorts, with median BMI remaining high in the Central and North-West regions, whereas stabilization and in some cases a decline were observed elsewhere. CONCLUSIONS BMI of Swiss conscripts is associated with individual and abSEP and urbanicity. Results show regional variation in the levels and temporal trajectories of BMI growth and signal their possible slowdown among recent birth cohorts.

Im Russischen Reich bildete sich ab den 1860er Jahren im Untergrund eine radikale Gegenelite heraus, welche die bisher geltenden Autoritäten, Konventionen und Werte in Frage stellte und durch etwas Besseres ersetzen wollte. In diesen Netzwerken fanden vor allem junge Menschen aus dem europäischen Teil des Russischen Reiches zusammen. Nationale Identitäten schienen sekundär. Russisch diente als Verständigungssprache. Entscheidend für die Aufnahme in diese Gegengesellschaft war einerseits die „persönliche Qualifikation“, andererseits eine gewisse schulische Bildung. Die verschiedensten radikalen Netzwerke können als Gesamtheit mit dem Begriff radikales Milieu gefasst werden. Dabei lehne ich mich an den Milieubegriff des Soziologen M. Rainer Lepsius an. Dieser definierte Milieus als „soziale Einheiten, die durch eine Koinzidenz mehrerer Strukturdimensionen […] gebildet werden.“ (Demokratie in Deutschland, 1993, 38). Die Strukturdimensionen des radikalen Milieus in Russland von den 1860er Jahren bis 1917 waren: a) Intellektuelle, meist „privilegierte“, städtische Mitglieder, b) Organisation in Zirkeln, c) eine Identität als Gegengesellschaft mit Gegenwerten, die eine Gegenrealität aufbaute sowie d) die Zugehörigkeit durch Kooptation. Obwohl sie den autokratischen Staat ablehnten, organisierten sich die Radikalen aber im imperialen Raum; ihre soziale Zusammensetzung spiegelte mit bestimmten Einschränkungen die ethnische und soziale Pluralität des Gesamtreiches wieder. In ihren autobiographischen Texten deuteten sich die Radikalen als „imperiale Gegenelite“. Dabei lässt sich auch ein Gefälle zwischen Zentrum und Peripherie feststellen: Die führenden Zirkel befanden sich meist in den grossen Städten des Reiches wie St. Petersburg, Moskau und Kiew oder im Exil und waren von dort aus gegenüber den Sympathisanten in den Provinzstädten oder gegenüber den Verbannten in Sibirien bei der Setzung interner Diskurse wegweisend.
