Pancreatic cancer is one of the most aggressive solid tumors and still has a poor prognosis. A delayed diagnosis at advanced stages and a poor response to systemic treatment frequently make a curative treatment impossible. Therefore, the identification of high-risk patients and screening them regularly is the most promising approach to improve the prognosis. ⋯ Furthermore, familial syndromes and germline mutations also confer an increased risk for development of pancreatic cancer. This article provides an overview of the various premalignant diseases of the pancreas. The value of the various imaging modalities, such as magnetic resonance imaging and endosonography are particularly discussed as well as the screening interval and the indications for surgical treatment are explained.

The diagnostics and treatment of Helicobacter pylori infections are subject to continuous changes and adaptations. Due to the increase of resistance rates to frequently used antibiotics, especially clarithromycin and the lack of new antibacterial substances as well as new developments in the diagnostics, particularly new procedures for resistance testing, the guidelines have to be updated regularly. In this article new directions and trends of the forthcoming European and German guidelines are summarized, categorized and discussed by the authors involved in the compilation of future guidelines.

The parenterally transmittable hepatitides B, D and C and their complications are a problem worldwide and also in Germany that should not be underestimated. Due to the estimated high gray area, a broad distribution, particularly by drug abuse, increasing prevalence due to immigration and a pandemic-related delay in the diagnostics, the identification of affected persons and therefore potentially infectious patients represents a great challenge for the healthcare system. ⋯ A new treatment concept with inhibition of virus uptake for treatment of hepatitis D first became available in September 2020. For all patients a long-term further monitoring is necessary when advanced liver damage or even liver cirrhosis occurs, especially for the exclusion of liver cell carcinoma.
