[Case-based learning with practical exercises in the course hygiene and microbiology as a model for the implementation of the new medical licensing regulations].
Within the scope of an educational improvement project, the teaching concept of the course hygiene and microbiology at the Goethe-University in Frankfurt was transferred from an organ system-based teaching concept into a case-based teaching concept. Concomitantly, this transformation was qualitatively reviewed to evaluate self-perceived learning success. ⋯ Overall, the implementation of a case-based teaching concept with practical elements in the course hygiene and microbiology increases the ability of medical students to understand the relevance of core knowledge and improves self-perceived learning. The fusion of theoretical and clinical contents elements in the course hygiene and microbiology meets the new national medical licensing regulations in Germany and promises to be a sustainable concept for clinical-theoretical subjects like hygiene and microbiology.

The leading symptom "acute dyspnea" and the causal underlying diseases have a high risk potential for an unfavorable course of treatment with a high letality. This overview of possible causes, diagnostic procedures and guideline-based therapy is intended to help implement a targeted and structured emergency medical care in the emergency department. The leading symptom "acute dyspnea" is present in 10% of prehospital and 4-7% of patients in the emergency department. ⋯ In critically ill patients in the non-traumatologic resuscitation room, respiratory disorders (B-problems) are present in 26-29%. In addition to cardiovascular disease, noncardiovascular disease may underlie "acute dyspnea" and requires differential diagnostic consideration. A structured approach can contribute to a high degree of certainty in the clarification of the leading symptom "acute dyspnea".

Case Reports[Rare cause of calf pain in a 56-year-old female patient: cystic adventitial degeneration of the popliteal artery].
Cystic adventitial degeneration (CAD) is a rare vascular disease, affects mostly middle-aged men, and as a nonatherosclerotic disease, is an uncommon differential diagnosis of intermittent claudication. ⋯ CAD should also be considered in female patients with atypical leg symptoms. There are no uniform treatment recommendations for CAD, which is why it is a challenge to select the optimal, usually interventional procedure. In patients with few symptoms and no critical ischemia, a conservative approach with close follow-up may be justified, as in our case report.

Convalescent plasma was discussed as a therapeutic option early in the course of the COVID-19 pandemic. However, until the onset of the pandemic, only the results of mostly small single-arm studies in other infectious diseases were available, which did not prove efficacy. In the meantime, the results of more than 30 randomized trials of COVID-19 convalescent plasma (CCP) for treatment of COVID-19 are available 1. Despite the heterogeneity of the results, conclusions for an optimal use are possible.

Acute limb ischemia is a vascular emergency and current guidelines emphasize the need for rapid treatment in a vascular center with an option of open surgical and interventional revascularization. Endovascular revascularization options for acute limb ischemia are increasingly focused on a wide range of mechanical thrombectomy devices based on different operating principles. For patients with acute limb ischemia in the setting of covid-19 infection high mortality rates and low technical success rates of revascularization procedures have been described.
