In prostate cancer, reliable information about the lymph node status is of great importance for accurate staging and the optimal planning of treatment. Despite recent advances in imaging, the histological detection of metastases, or pelvic lymphadenectomy (PLND), continues to be the most reliable method for lymph node staging in clinically localised prostate cancer, especially as this procedure enables the detection of small or micrometastases. Radioisotope-guided sentinel PLND (sPLND) demonstrates high sensitivity in the detection of lymph node metastases as well as low morbidity in prostate cancer because of the targeted removal of a relatively small number of lymph nodes...

The uncertainty of whether/how to treat asymptomatic patients with isolated severe aortic stenosis and normal left ventricular ejection fraction is one of the most topical in cardiovascular medicine. Recently, the AVATAR trial: first ever randomized trial in the setting of aortic stenosis has been started in an attempt to adequately address this 'burning issue'. In light of this fact it is important to identify biomarkers which might help in risk stratification of these patients, not only in the referring physician's office during a routine exam, but also for preoperative patients scheduled for surgical replacement/transcatheter aortic valve implantation...

BACKGROUND: Surgical site infections (SSI) are one of the most frequent postoperative complications worldwide and preventive measures are still an important research topic. High infection rates are not uncommon, especially in visceral surgery. At the same time, frequently not all evidence-based measures are carried out in a standardized manner. The aim of this article is to summarize the relevant literature on evidence-based measures for prevention of SSI. Although evidence-based medicine has already become well-established in surgery, the opinion of experts often still prevails...
