An outbreak of foot rot occurred in the ibex colony "Vanil Noir" in Switzerland from May to December 2014. This article describes field observations and the analyses carried out on the limbs of 3 animals submitted for postmortem examination. Disease signs observed in the field included lameness, poor body condition and overgrown hooves. Macroscopic examination of selected limbs revealed severe lesions in all of them, including interdigital inflammation with ulceration and malodorous exudation. Histological changes were consistent with chronic laminitis with bone resorption, which was not detected at radiographical examination. Grocott-positive organisms compatible with Dichelobacternodosus were detected in the lesions. Samples collected from the lesions were positive by polymerase chain reaction for benign D. nodosus, which is typically associated with only mild lesions in domestic sheep. Whether D. nodosus is endemic in the colony or had previously been transmitted from sympatric domestic livestock is unclear. The unusual warm and humid weather conditions in 2014 may well have contributed to the outbreak.

Foot-and-mouth disease (FMD) is a highly contagious disease that caused several large outbreaks in Europe in the last century. The last important outbreak in Switzerland took place in 1965/66 and affected more than 900 premises and more than 50,000 animals were slaughtered. Large-scale emergency vaccination of the cattle and pig population has been applied to control the epidemic. In recent years, many studies have used infectious disease models to assess the impact of different disease control measures, including models developed for diseases exotic for the specific region of interest. Often, the absence of real outbreak data makes a validation of such models impossible. This study aimed to evaluate whether a spatial, stochastic simulation model (the Davis Animal Disease Simulation model) can predict the course of a Swiss FMD epidemic based on the available historic input data on population structure, contact rates, epidemiology of the virus, and quality of the vaccine. In addition, the potential outcome of the 1965/66 FMD epidemic without application of vaccination was investigated. Comparing the model outcomes to reality, only the largest 10% of the simulated outbreaks approximated the number of animals being culled. However, the simulation model highly overestimated the number of culled premises. While the outbreak duration could not be well reproduced by the model compared to the 1965/66 epidemic, it was able to accurately estimate the size of the area infected. Without application of vaccination, the model predicted a much higher mean number of culled animals than with vaccination, demonstrating that vaccination was likely crucial in disease control for the Swiss FMD outbreak in 1965/66. The study demonstrated the feasibility to analyze historical outbreak data with modern analytical tools. However, it also confirmed that predicted epidemics from a most carefully parameterized model cannot integrate all eventualities of a real epidemic. Therefore, decision makers need to be aware that infectious disease models are useful tools to support the decision-making process but their results are not equal valuable as real observations and should always be interpreted with caution.

Stefan Zweig arrive en Suisse en novembre 1917. D’abord libéré du service militaire pour deux mois, il obtient finalement la permission de rester en Suisse jusqu’à la fin de la guerre. Il peut ainsi assister aux répétitions et à la première de Jérémie, sa pièce de théâtre pacifiste représentée pour la première fois au Stadttheater de Zurich en février 1918. Son séjour en Suisse est également marqué par le développement de son admiration et de son amitié pour Romain Rolland – celui qu’il désigne comme étant « la conscience morale de l’Europe ». L’objet de cet article est de montrer que la conjonction Suisse–Rolland a joué un rôle absolument essentiel dans la vie personnelle et créatrice de Zweig.

Peripheral arteriovenous malformations (AVM) remain most challenging among various congenital vascular malformations to be treated. Here we present three illustrative patients with Yakes type IIIb and type IV AVM at the plantar aspect of the foot who were successfully treated by minimally invasive embolization. The value of the Yakes AVM classification system to guide the therapeutic decision making by directing specific therapeutic procedures to specific AVM types defined by their angioarchitecture is demonstrated. Direct percutaneous AVM puncture with coiling of aneurysmal outflow vein and subsequent ethanol embolization is shown. Finally, the report illustrates that several AVM types can coexist.
