Review[Evidence-based cosmetics: concepts and applications in photoaging of the skin and xerosis].
As well as for topically used dermatological agents, studies performed according to the rules of evidence-based medicine (EBM) are also needed for cosmetics. Although the concept of evidence-based cosmetics has been only partly developed so far, there are some agents and preparations available that can be considered as evidence-based. In this paper we present data from several studies that claim to have examined and demonstrated the efficacy of cosmetic preparations for the management of solar damage and aging skin as well as lentigo and melanosis according to EBM criteria. ⋯ However, the lack of controlled studies confirming the efficacy of dermocosmetic products as well as the superiority of the preparation incorporating the active agent over the corresponding base is a problem yet to be solved. Undoubtedly, the efficacy and the sustainability of the achieved effects have to be examined and proven accordingly to EBM criteria in further active cosmetic agents. Moreover, generally accepted guidelines for the examination of efficacy and tolerability of dermocosmetics have to be developed.

ReviewThe European surveillance activities EARSS and ESAC in the context of ABS International.
Development of resistance obstructs the successful use of antimicrobial drugs, since shortly after each and every introduction of a new antibiotic resistant pathogens have emerged. The hope of being able to reverse or at least slow down the occurrence of antibiotic resistance has led to a number of actions and initiatives. ⋯ The data generated by EARSS and ESAC are an essential prerequisite for targeted interventions to cope with the problem of antibiotic resistance. The project ABS International constitutes an impressive initiative to optimize the situation in hospitals in nine European member states.

Prolongation of the ventricular repolarisation manifests itself as a prolongation of the QT intervall on the surface ECG and represents a major risk for a special form of ventricular tachycardia called "torsades de pointes". Torsades de pointes are often self limited and are associated with palpitations, dizziness or syncope. Degeneration into ventricular fibrillation and sudden cardiac death can occur. ⋯ Repeated ECG controls during therapy with QT prolonging drugs are mandatory, especially when drug doses are changed, additional drugs are prescribed, or in case of vomiting and diarrhea. QT prolongation in individual medical therapy is not always predictable. Therefore, updated lists of drugs with the potential of QT prolongation are available on the Internet (e.g. www.qtdrugs.org ).

ReviewAntibiotic stewardship through the EU project "ABS International".
The increasing problem of antimicrobial resistance requires implementation of antibiotic stewardship (ABS) programs. The project "ABS International--implementing antibiotic strategies for appropriate use of antibiotics in hospitals in member states of the European Union" was started in September 2006 in Austria, Belgium, the Czech Republic, Germany, Hungary, Italy, Poland, Slovenia and Slovakia. ⋯ Specific ABS tools are being implemented in up to five healthcare facilities in each country. Although ABS International clearly focuses on healthcare institutions, future antimicrobial stewardship programs must also cover public education and antibiotic prescribing in primary care.

Gastrinomas are functional neuroendocrine tumors of the gastroenteropancreatic system. Surgery is first line treatment in gastrinomas, however often fails to be curative. This manuscript reviews current strategies of medical treatment of surgically non-curable gastrinoma. ⋯ In well differentiated neuroendocrine carcinoma (G1 and G2) a so-called biotherapy with somatostatin analogues exists as first-line and chemotherapy with streptocotozin plus doxorubicine/5-FU as second-line medical treatment option. In poorly differentiated neuroendocrine carcinoma (G3) chemotherapy with etoposide plus cisplatin is possible. Prospective future therapeutic strategies may include treatment with novel somatostatin analogues as well as angiogenesis inhibitors and kinase inhibitors targeting tumor-specific signaling cascades.
