Muslime in Ruanda – von Marginalisierung zu Integration /// Arbeitspapiere / Institut für Ethnologie und Afrikastudien ; 74

Zwischen April und Juni 1994 wurden in dem kleinen zentralafrikanischen Land Ruanda ca. 800.000 Menschen ermordet worden. Die Mehrzahl der Opfer waren Tutsi, aber auch viele Hutu verloren ihr Leben. Nahezu jede internationale und nationale Organisation versagte im Angesicht des Ausmaßes der Tragödie. Auch die in Ruanda sehr einflussreiche katholische Kirche konnte oder wollte die Massaker nicht beenden. Einzig die in der ruandischen Geschichte bis zum Genozid immer marginalisierten Muslime verweigerten in der Mehrzahl eine Teilnahme an den Massakern. Warum es zu diesem Verhalten kam, steht als Ausgangsfrage zu Beginn der Untersuchung. Im Folgenden gliedert sich die Arbeit in drei Teile – Geschichte des Islam bis 1994, Verhalten der Muslime im Völkermord von 1994 und die Veränderungen in den zehn Jahren nach dem Genozid. Die Arbeit, welche sich auf die Ergebnisse einer zweimonatigen Feldforschung und einige ältere Arbeiten zum Thema stützt, macht deutlich, dass die Geschichte der ruandischen Muslime bis 1994 durch eine kontinuierliche Marginalisierung gekennzeichnet war. Als nach dem Völkermord das außergewöhnliche Verhalten der ruandischen Muslime langsam deutlich wurde, änderte sich bei vielen Menschen und auch bei offiziellen Stellen auch die Einstellung gegenüber Muslimen.

Microsurgical reconstruction of the head and neck - Current practice of maxillofacial units in Germany, Austria, and Switzerland

Refinement in microvascular reconstructive techniques over the last 30 years has enabled an increasing number of patients to be rehabilitated for both functional and aesthetic reasons. The purpose of this study was to evaluate different microsurgical practice, including perioperative management, in Germany, Austria, and Switzerland. The DÖSAK collaborative group for Microsurgical Reconstruction developed a detailed questionnaire which was circulated to units in the three countries. The current practice of the departments was evaluated. Thirty-eight questionnaires were completed resulting in a 47.5% response rate. A considerable variation in the number of microsurgical reconstructions per year was noted. In relation to the timing of bony reconstruction, 10 hospitals did reconstructions primarily (26.3%), 19 secondarily (50%) and 9 (23.7%) hospitals used both concepts. In the postoperative course, 15.8% of hospitals use inhibitors of platelet aggregation, most hospitals use low molecular heparin (52.6%) or other heparin products (44.7%). This survey shows variation in the performance, management, and care of microsurgical reconstructions of patients. This is due in part to the microvascular surgeons available in the unit but it is also due to different types of hospitals where various types of care can be performed in these patients needing special perioperative care.

Delivery room management of very low birth weight infants in Germany, Austria and Switzerland--a comparison of protocols

Surveys from the USA, Australia and Spain have shown significant inter-institutional variation in delivery room (DR) management of very low birth weight infants (VLBWI, <1500g) at birth, despite regularly updated international guidelines.

Behaviour of general dental practitioners in Germany regarding posterior restorations with flowable composites

Because the recommendation to use flowables for posterior restorations is still a matter of debate, the objective of this study was to determine in a nationwide survey in Germany how frequently, for what indications, and for what reasons, German dentists use flowable composites in posterior teeth. In addition, the acceptance of a simplified filling technique for posterior restorations using a low stress flowable composite was evaluated. Completed questionnaires from all over Germany were returned by 1,449 dentists resulting in a response rate of 48.5%; 78.6% of whom regularly used flowable composites for posterior restorations. The most frequent indications were cavity lining (80.1%) and small Class I fillings (74.2%). Flowables were less frequently used for small Class II fillings (22.7%) or other indications (13.6%). Most frequent reasons given for the use of flowables in posterior teeth were the prevention of voids (71.7%) and superior adaptation to cavity walls (72.9%), whereas saving time was considered less important (13.8%). Based on the subjective opinion of the dentists the simplified filling technique seemed to deliver advantages compared to the methods used to date particularly with regard to good cavity adaptation and ease of use. In conclusion, resin composites are the standard material type used for posterior restorations by general dental practitioners in Germany and most dentists use flowable composites as liners.

Current state of evidence on 'off-label' therapeutic options for systemic lupus erythematosus, including biological immunosuppressive agents, in Germany, Austria and Switzerland--a consensus report

Systemic lupus erythematosus (SLE) can be a severe and potentially life-threatening disease that often represents a therapeutic challenge because of its heterogeneous organ manifestations. Only glucocorticoids, chloroquine and hydroxychloroquine, azathioprine, cyclophosphamide and very recently belimumab have been approved for SLE therapy in Germany, Austria and Switzerland. Dependence on glucocorticoids and resistance to the approved therapeutic agents, as well as substantial toxicity, are frequent. Therefore, treatment considerations will include 'off-label' use of medication approved for other indications. In this consensus approach, an effort has been undertaken to delineate the limits of the current evidence on therapeutic options for SLE organ disease, and to agree on common practice. This has been based on the best available evidence obtained by a rigorous literature review and the authors' own experience with available drugs derived under very similar health care conditions. Preparation of this consensus document included an initial meeting to agree upon the core agenda, a systematic literature review with subsequent formulation of a consensus and determination of the evidence level followed by collecting the level of agreement from the panel members. In addition to overarching principles, the panel have focused on the treatment of major SLE organ manifestations (lupus nephritis, arthritis, lung disease, neuropsychiatric and haematological manifestations, antiphospholipid syndrome and serositis). This consensus report is intended to support clinicians involved in the care of patients with difficult courses of SLE not responding to standard therapies by providing up-to-date information on the best available evidence.

Characterization of Aggregatibacter actinomycetemcomitans strains in periodontitis patients in Germany

Aggregatibacter actinomycetemcomitans strains of serotype b and with a deletion of 530 bp in the promoter region of the leukotoxin gene (JP2 clone) are known to be associated with severe periodontitis. Our study was aimed to detect virulence genes of A. actinomycetemcomitans strains obtained from patients living in four German cities with different proportions of immigrants.

Seroprevalence of Taenia saginata cysticercosis in the federal state of Lower Saxony in Germany

Based on ELISA results from randomly selected serum samples taken from 128 cattle from different administrative and urban districts in the federal state of Lower Saxony in Germany a seroprevalence estimate of Taenia saginata cysticercosis in this area was derived. This estimate was subsequently used to calculate the sample size required in an epidemiological study to determine the actual prevalence of this infection in the cattle population (n = 2 604 767) in this federal state. The sample size was calculated as 1518 and the samples were collected according to the distribution of cattle among the 48 administrative and urban districts in Lower Saxony. The samples were tested with an evaluated antibody ELISA. The results showed a positive antibody titre rate of 8.83% from the total tested samples.
