Comparative StudyDifferences in critical care practice between an industrialized and a developing country.
Few data are available on intensive care unit (ICU) patient populations and critical care medicine practices in developing countries. ⋯ Patient characteristics and ICU practices varied significantly between the two ICUs. Mortality was substantially greater at MonICU, particularly among patients suffering from multiple-organ dysfunction. Strategies to improve the care of critically ill patients at MonICU should address both system- and staff-related problems, improve acceptance of the ICU service among physicians of other disciplines and upgrade the training of ICU staff.

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 ).

Pharmacodynamic interaction between monodesbutyl-benflumetol and artemisinin as well as proguanil in Plasmodium falciparum in vitro.
The sensitivity of Plasmodium falciparum against artemisinin, monodebutyl-benflumetol (DBB) and a 1:3 m/m combination of both compounds was assessed in 51 fresh parasite isolates. Although a comparison between fully inhibitory concentrations (GMCOC) of artemisinin alone (63.33 nM), DBB alone (50.15 nM) and the combination (23.92 nM) indicated significant synergism between artemisinin and DBB, this was less evident when comparing the log-probit regressions. Moreover, the geometric mean values of the fractional inhibitory concentrations (SFIC) showed a rising tendency with increasing EC level. ⋯ Proguanil alone showed weak blood schizontocidal activity. The log-probit regressions indicated higher activity of the combination as compared to DBB alone. The SFIC values indicated moderate synergism between DBB and proguanil that could be an advantage in an eventual therapeutic and prophylactic use of DBB.

Food-borne zoonoses, the EU zoonosis legislation and the prospects for food safety and consumer protection during primary animal production.
Zoonoses are diseases that are transmitted naturally between animals and humans. The control of food-borne zoonoses within the European Union is a prerequisite for assuring a functional internal market and consequently represents an important item on the political agenda. Unfortunately, until recently, gaining a clear view of the current incidence of food-borne zoonoses and the prevalence of its causative agents has been frustrated by the absence of reliable monitoring and reporting systems. ⋯ The European Union has adopted legislation to remedy this situation and to control food-borne zoonoses in primary production. This contribution discusses the incentives for introducing EU Directive 2003/99/EC and EU Regulation No. 2160/2003, summarises their essentials and discusses major ramifications of both pieces of legislation for the prevention of food-borne zoonoses. It is concluded that there is reason for cautious optimism concerning human salmonellosis, while for other food-borne zoonoses there should be a call for action.
