Meta AnalysisMortality after hydroxyethyl starch 130/0.4 infusion: an updated meta-analysis of randomized trials.
Hydroxyethyl starch (HES) is in widespread clinical use for volume therapy with colloids. According to the most recent meta-analysis performed in 2010, published studies are of poor quality and report too few events to reliably estimate the benefits or risks of administering 6% HES 130/0.4. As results from new trials, reporting on a large number of events became available in 2011 and 2012, an updated meta-analysis was performed. ⋯ Large-scale trials should help more precisely to determine the effect of HES 130/0.4 on mortality. In the interim, best current evidence suggests a trend toward higher mortality among HES 130/0.4 recipients.

Clinical TrialPrevention and control of surgical site infections: review of the Basel Cohort Study.
Surgical site infections (SSI) are the most common hospital-acquired infections among surgical patients, with significant impact on patient morbidity and health care costs. The Basel SSI Cohort Study was performed to evaluate risk factors and validate current preventive measures for SSI. The objective of the present article was to review the main results of this study and its implications for clinical practice and future research. ⋯ The Basel SSI Cohort Study suggested that SAP should be administered between 74 and 30 minutes before surgery. Due to the observational nature of these data, corroboration is planned in a randomized controlled trial, which is supported by the Swiss National Science Foundation. Routine change of gloves or double gloving is recommended in the absence of SAP. Anaemia, transfusion and tutorial assistance do not increase the risk of SSI. The substantial economic burden of in-hospital SSI has been confirmed. SSI surveillance by the surgical staff detected only half of all in-hospital SSI, which prompted the introduction of an electronic SSI surveillance system at the University Hospital of Basel and the Cantonal Hospital of Aarau. Due to the absence of multiresistant SSI-causing pathogens, the continuous use of single-shot single-drug SAP with cefuroxime (plus metronidazole in colorectal surgery) has been validated.

ReviewNeglected tropical diseases: diagnosis, clinical management, treatment and control.
Branded in 2005, "neglected tropical diseases" have gained traction in terms of advocacy, interest for research, enhanced funding and political will for their control and eventual elimination. Starting with an initial set of 13 neglected tropical diseases--seven helminth, three bacterial and three protozoal infections--the list considerably expanded to more than 40 diseases that now also includes viral, fungal and ectoparasitic infections. In this review, we provide a comprehensive overview of the neglected tropical diseases, their causative agents and the current geographical distribution, including their importance for the general practitioners seeing returning travellers and migrants in Switzerland. ⋯ With an emphasis on neglected tropical diseases due to helminths, protozoa and ectoparasites, we review common diagnostic methods and current recommendations for treatment at the population level and the individual patient, thereby juxtaposing the situation in highly endemic countries on one side, with Switzerland on the other. We highlight the clinical presentation and management of the neglected tropical diseases in general and then elaborate on two examples, strongyloidiasis and leptospirosis. Our review provides a global perspective of neglected tropical diseases and we hope that it will prove useful for the general practitioner and clinician in Switzerland and elsewhere to enhance their suspicion index, differential diagnosis, clinical management and treatment, including referral to specialised clinics and laboratories when need be.

Comparative StudyManagement and outcome of severely elevated blood pressure in primary care: a prospective observational study.
In primary care the management of patients with acute severely elevated blood pressure (BP) is challenging. The aim of the study was to evaluate the initial management and outcome of patients presenting to their general practitioner (GP) with severe high blood pressure. ⋯ The majority of 164 patients who presented with acutely and severely elevated blood pressure (BP >180 +/or >110 mm Hg) to their GPs was asymptomatic, had pre-existing hypertension and was managed in GP's office unless a hypertensive emergency was present. At three month follow-up mean systolic BP was still above target values.
