ReviewWherefrom and whereabouts of an alien: the American liver fluke Fascioloides magna in Austria: an overview.
The giant liver fluke Fascioloides magna, an invasive species originating from North America, was recorded in Austria in the wild for the first time in 2000. Since then, various data concerning the epidemiology in snail intermediate hosts and cervid final hosts have been reported. Galba truncatula acts as snail intermediate host, and red deer, roe deer and fallow deer act as final hosts. ⋯ Because eradication after medical treatment was unsuccessful, and due to the risk of further spread of the parasite into unaffected regions, enhanced control strategies need to be developed. We recommend assessment of introduction pathways and dispersal, continuous monitoring of host abundance and distribution and the prevalence of flukes in intermediate and final hosts, as well as coordinated and concerted actions with neighbouring countries. This strategy could help to reduce potential negative impacts of this and other invasive parasites on host populations in Europe.

Evaporation of free water causes concentrational alkalosis in vitro.
The development of metabolic alkalosis was described recently in patients with hypernatremia. However, the causes for this remain unknown. The current study serves to clarify whether metabolic alkalosis develops in vitro after removal of free water from plasma and whether this can be predicted by a mathematical model. ⋯ Evaporation of water from serum causes concentrational alkalosis in vitro, with good agreement between measured and predicted acid-base values. At least part of the metabolic alkalosis accompanying hypernatremia is independent of renal function.

Leptospirosis is a ubiquitous and potentially fatal zoonosis with protean manifestations. Human infection commonly occurs through contact with contaminated water or soil. In developed countries, leisure or household activities are increasingly associated with the disease. ⋯ In this case series, we present their clinical course. Furthermore, we provide an overview on the spectrum of organ involvement, with an emphasis on kidney injury, and comment on pitfalls in establishing the diagnosis. The considerable variance in presentation-with admissions both to internal and neurological units-emphasises the high index of suspicion required to arrive at the right diagnosis, particularly in countries of perceived low risk such as Austria.

Clinical TrialTransurethral bladder neck incision in women with primary bladder neck obstruction.
Bladder outlet obstruction is an uncommon condition in women. Primary bladder neck obstruction is one of the functional causes of bladder outlet obstruction. We evaluated surgical treatment in our patients with primary bladder neck obstruction. ⋯ The diagnosis of primary bladder neck obstruction in women is based on typical symptoms, uroflowmetry and multichannel urodynamics, including electromyography. Videourodynamics is obligatory in doubtful cases. Transurethral bladder neck incision is an effective therapy for female patients with primary bladder neck obstruction, and if necessary, a second procedure can be safely performed.

Clinical TrialMigration characteristics and early clinical results of a novel-finned press-fit acetabular cup.
Ana Nova® is a novel-finned press-fit acetabular cup which showed superior biomechanical characteristics in an experimental set-up. Using Einzel Bild Röntgen Analyse (EBRA) measurements should offer the opportunity to predict implant survival at an early stage. The purpose of this study was to assess migration and clinical outcome 2 years after total hip replacement by a novel-finned press-fit acetabular cup. ⋯ Adverse migration data in this study might predict aseptic loosening and decreased survival of the implant. According to previous studies, it is possible that this effect occurred because of limited accuracy of the EBRA system. In our opinion, migration analyses may not be recommended as a screening tool in a 2 year follow-up.
