Electronic Outbreak Surveillance in Germany: A First Evaluation for Nosocomial Norovirus Outbreaks
Anja M. Hauri,Hans-Jürgen Westbrock,Herman Claus,Steffen Geis,Siegfried Giernat,Michael Forβbohm,Helmut Uphoff
PLOS ONE , 2012, DOI: 10.1371/journal.pone.0017341
Abstract: In Germany, surveillance for infectious disease outbreaks is integrated into an electronic surveillance system. For 2007, the national surveillance database contains case-based information on 201,224 norovirus cases, three-quarters of which are linked to outbreaks. We evaluated the data quality of the national database in reflecting nosocomial norovirus outbreak (NNO) data available in 19 Hessian local public health authorities (LPHAs) and the influence of differences between LPHA's follow-up procedures for laboratory notifications of Norovirus positive stool samples on outbreak underascertainment.
Interaction of Navigation with Minimal Access Surgery  [PDF]
Siegfried Beller
Surgical Science (SS) , 2012, DOI: 10.4236/ss.2012.36059
Abstract: Minimal access surgery (MAS) includes conventional minimally invasive laparoscopic and thoracoscopic surgery, single incision laparoscopic surgery (SILS) and natural orifice transluminal endoscopic surgery (NOTES). An end of the evolution of MAS is not foreseeable, but there are still limitations. In the most common fields of intestinal surgery (cholecystectomy, appendectomy, colo-rectal resection) limitations of MAS shook dogma for surgical strategy and procedure. Automation units and telesurgical systems try to assist the surgical action. Remaining limitations are caused by lack of tactile sense and spatial awareness. With expanding application of minimal access technique in surgery the need for navigation assistance will increase. Future expansion is basically reliant on the feasibility of navigated surgery. Navigation must respect the problems of organ shift and realise continuous localisation of the surgical target as well as spatial orientation of surgical instruments and camera view.

Conflitos e convergências na ALCA numa perspectiva de vantagens comparativas reveladas de países das Américas
Bender, Siegfried;
Economia Aplicada , 2006, DOI: 10.1590/S1413-80502006000100007
Abstract: in this paper the industry sectors' revealed comparative advantages for 12 americas' countries were calculated from 1981 to 1999. the countries' revealed comparative advantage patterns are then used to establish the similarity degree among these 12 countries. this similarity degree gives us both an indication of the economic costs in a commercial integration and also some insights about incentives that sub-groups of countries have to act as a group in a negotiation for commercial integration. the results show that these 12 countries can be grouped in three subsets of countries distinct to each other subset, that the economic costs of commercial integration among these 12 countries (alca) is relatively high, and that there is a sub-group of south american countries that are similar among them, which therefore have a natural incentive to negotiate as a group in a commercial integration process like alca.
De eerste etnografische monografie: De Kaffers aan de Zuidkust van Afrika (1810) van Lodewyk Alberti

Abstract: This paper examines the ethnographic discourse in the first ethnographic monograph which appeared in the Netherlands, De Kaffers aan de Zuidkust van Afrika, Natuur- en Geschiedkundig beschreven (1810) by Lodewyk Alberti. Within a European context this book is unique for being the only successful implementation of the ethnographic questionnaire of Joseph-Marie Degérando, the Considérations sur les diverses méthodes a suivre dans l'observation des peuples sauvages (1800), and the anthropological ideas of the Société des Observateurs de l'homme. In Alberti's case, this resulted principally into a focus on the cultural aspects of ethnographical description. Furthermore, Alberti was the first to proof the usefulness of ethnographic knowledge in the management of colonial relationships. The personal aim of his book was to apply for the position of landdrost of Uitenhage, assuming that the Cape Colony could be restored to Dutch rule, which was in 1810 still a possibility.
Etanercept, improved dosage schedules and combinations in the treatment of psoriasis: an update

Abstract: anercept, improved dosage schedules and combinations in the treatment of psoriasis: an update Review (4723) Total Article Views Authors: Siegfried Segaert Published Date August 2009 Volume 2009:2 Pages 29 - 36 DOI: http://dx.doi.org/10.2147/JIR.S4405 Siegfried Segaert Department of Dermatology, University Hospital Leuven, Belgium Abstract: Etanercept, a subcutaneously administered fully human soluble tumor necrosis factor (TNF) receptor, was initially approved for the treatment of psoriasis at a dose of 25 mg twice weekly in repeated 24-week cycles with the possibility to double the dose in the first 12 weeks of the first cycle. During intermittent treatment, patients retain their ability to respond to etanercept. Recently, a new dosing schedule of etanercept 50 mg once weekly was approved, based on a study in which PASI-75 (75% improvement of Psoriasis Area and Severity Index) was achieved by 37% and 71% of patients at week 12 and 24. Another study demonstrated a PASI-75 of 57% and 69% in pediatric psoriasis patients receiving etanercept 0.8 mg/kg (up to 50 mg) once weekly for 12 and 24 weeks respectively, resulting in European approval from age 8. Based on recent clinical trials, the antipsoriatic effect of etanercept can be markedly increased in combination with acitretin, methotrexate or UVB. The combination with acitretin appears attractive because of its non-immunosuppressive and chemopreventive properties. Etanercept–methotrexate combination therapy is well established in rheumatologic patients. From a long-term perspective, the combination of TNF-inhibitors with phototherapy (photocarcinogenesis) or cyclosporine (carcinogenesis, infections) warrants great caution however. Finally, combination with topical calcipotriol–betamethasone ointment may increase the speed of response to TNF-inhibitors in the first 4 weeks of treatment.

Abstract: Der Sonderforschungsbereich 186, lokalisiert in Bremen, hat seit 1988 sich in seinen Projekten dem Gegenstand "Statuspassagen und Lebenslauf" gewidmet. Er untersuchte die Strukturierung von Lebensl ufen auf der Basis institutioneller Rahmenbedingungen und individueller Handlungsstrategien. Dabei wurde grunds tzlich theoretisch differenziert zwischen Lebenslauf und Biografie und mithin Lebensverlaufs- und Biografieforschung praktiziert. W hrend erstere im L ngsschnitt die Abfolge von "objektiven" Ereignissen verfolgt und damit dem quantitativen Paradigma empirischer Forschung sich verpflichtet fühlt, geht es letzterer um die subjektive Rekonstruktion der Lebensgeschichte auf der Basis qualitativer Methoden. Um eine m glichst ganzheitliche strukturtreue Abbildung der Realit t zu erzielen, strebt der Forschungsbereich insgesamt (wie auch einige Teilprojekte) eine Methodenintegration an. Der Beitrag referiert nun einzelne, zentrale und inhaltliche Befunde der Arbeit des Sonderforschungsbereiches auf der Basis der vier Abschlussver ffentlichungen und prüft zugleich, inwieweit der Versuch einer Methodenintegration gelungen ist und eine Methodeninnovation mit Erkenntnisfortschritt darstellt. URN: urn:nbn:de:0114-fqs020454 The Special Research Centre 186 ("Sonderforschungsbereich") on "Status-Passages and Life-Course" at Bremen was initiated in 1988. Last year, members of the centre published four volumes summarising some of their main results. Basically, they differentiate theoretically and empirically between "life-course" and "biography". While life-course studies refer to quantitative statistical methods by enumerating accumulated life events, qualitative, biographical studies are attempts at accumulating information about the personal reconstructions of life histories. The methodological and theoretical intention of this empirical research is to combine and, furthermore, integrate qualitative and quantitative methods in order to receive a better insight into the phenomena of "status-passages." This review essay informs the reader about some important, substantive findings of the Special Research Centre and attempts to answer the question, whether the aim of integrating qualitative and quantitative methods was successfully realised, in order to get more reliable and valid results.

Abstract: Los estándares de formación son unos medios auxiliares del sistema escolar de ense anza en Alemania. Establecen los contenidos cognitivos generales, representados por aquellas aptitudes intelectuales que los alumnos han de poseer al terminar los distintos ciclos del sistema escolar. Vienen a ser los objetivos de la ense anza, entendidos no como ordenados conocimientos científicos de asignaturas separadas, sino como unas aptitudes, llamadas competencias, que permiten unos logros interesantes en ámbitos diversos. Esto antes se llamaba instrucción formal . Los estándares de formación describen el output escolar deseado. La Conferencia alemana de Ministros de Educación ha establecido los estándares de formación que se aplican en las escuelas de Alemania, pero todavía no está clara la vinculación de estos con los planes de estudios. Sobre los estándares de formación hay cuestiones todavía no resueltas, pero se espera que sirvan para aumentar la calidad de la educación. _____________________________________________________________________________________________________________________________________________________________________ Les standards de formation constituent l’un des moyens auxiliaires du système d’enseignement scolaire en Allemagne. Ils déterminent les contenus cognitifs généraux, représentés par les aptitudes intellectuelles que les élèves doivent posséder en terminant les différents cycles du système scolaire. Ils en deviennent les objectifs de l’enseignement, compris non comme des connaissances scientifiques ordonnées de thèmes séparés sinon comme des aptitudes, appelées compétences, qui permettent des réussites intéressantes dans des domaines divers. Cela s’appelait autrefois l’instruction formelle . Les standards de formation décrivent l’output scolaire souhaité. La Conférence allemande des Ministres de l’éducation a mis en place les standards de formation qui sont appliqués dans les écoles d’Allemagne, mais le lien entre ceux-ci et les cursus n’est toujours pas clair. Il y a sur les standards de formation des questions toujours non résolues mais l’on espère cependant que ceux-ci serviront à augmenter la qualité de l’enseignement. In Germany, educational standards are an auxiliary aspect within the school system. They establish the general cognitive content, in the form of those intellectual aptitudes which pupils should achieve by the end of the various stages of their education. Thus, although they constitute teaching objectives this is not in the sense of structured scientific knowledge of distinct subjects; rather they describe a set
