Obesity and its comorbidities represent a worldwide growing health challenge. In Germany, at least 15 million people are suffering from this disease. To date, lifestyle modification is the most frequently used treatment modality, but offers only limited success concerning both the extent and the sustainability of weight loss, while surgical interventions are restricted to people with severe obesity (body mass index ≥40 kg/m2). ⋯ At present, only a few compounds (orlistat, liraglutide, amfepramon) are available for adjunct drug treatment of obesity in Germany. However, new principles and compounds that could revolutionize obesity management in the years to come are on the horizon. For alternative "slimming drugs", mainly dietary supplements, scientific evidence is lacking on efficacy or clinically meaningful weight loss.

This article reports two cases of patients with coronavirus disease 2019 (COVID-19) in which occlusion of large cerebral arteries occurred. These occurred in a female patient in the early stage of COVID-19 and in the second case in the late stage. ⋯ Coagulopathy in the course of COVID-19 can result in severe stroke with poor outcome even in younger patients. With respect to the etiology of arterial occlusions (COVID-19-induced hypercoagulopathy, cardiomyopathy, vasculitis) there is a necessity for further research.

Vaccination is considered one of the most important achievements of modern medicine and has saved millions of lives. As a result, the age-old fear of severe or fatal infectious diseases has largely been forgotten in society; however, the pandemic triggered by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) shows how quickly this fear can return. Also, many people have reservations about medical measures, especially if they are directed against vague dangers. ⋯ To counteract this development, this article provides information on basic vaccination principles, legal frameworks and components of vaccines. It explains the most important categories, goals, core elements of vaccination programs and the most important recommendations of the Standing Committee on Vaccination at the Robert Koch Institute (STIKO). It explains the current state of knowledge with respect to required resources, assessment of vaccine reactions, complication management and possible vaccine damage.

The case of an 82-year-old man who suffered from bone pain is reported. This was due to osteomalacia with hypophosphatemia. ⋯ The mesenchymal tumor could be detected at the elbow by positron emission tomography-computed tomography (PET/CT) scanning with 68 Ga-DOTATATE. After resection of this hemangiopericytoma (phosphaturic mesenchymal tumor, PMT) the phosphate level quickly returned to normal.
