Dengue fever is a common infectious disease in the tropical and subtropical zones, with more than 100 million symptomatic cases per year. Mosquitoes of the genus Aedes (Aedes aegypti, Aedes albopticus) are vectors of the disease, and their spread has led to rising case numbers around the world. Physicians in Europe, too, are increasingly being confronted by this challenge. ⋯ Climate change and global mobility have led to a worldwide increase in dengue fever. The disease only rarely takes a severe course. In such cases, rapid symptomatic treatment as needed is the key to the avoidance of severe complications.

The treatment options for patients with progressive malignant tumors despite primary radiotherapy are often limited. In selected cases, re-irradiation can be offered. This article concerns the selection criteria and results of re-irradiation for certain types of cancer. ⋯ Re-irradiation is a treatment option for selected cancer patients. As the available scientific evidence is limited, multidisciplinary collaboration and participatory decision-making are particularly important.

Observational epidemiological studies often yield different results on the same research question. In this article, we explain how this comes about. ⋯ The above reasons why epidemiological study results can be heterogeneous are explained in this review. Quantitative bias analyses and sensitivity analyses with alternative data evaluation strategies can help explain divergent results on one and the same question.
