An integrated assessment of environmental, economic, social and technological parameters of source separated and conventional sanitation concepts: A contribution to sustainability analysis.

Resource recovery and reuse from domestic wastewater has become an important subject for the current development of sanitation technologies and infrastructures. Different technologies are available and combined into sanitation concepts, with different performances. This study provides a methodological approach to evaluate the sustainability of these sanitation concepts with focus on resource recovery and reuse.

Assessment of nitrogen and phosphorus flows in agricultural and urban systems in a small island under limited data availability.

Nitrogen (N) and phosphorus (P) are two essential macronutrients required in agricultural production. The major share of this production relies on chemical fertilizer that requires energy and relies on limited resources (P). Since these nutrients are lost to the environment, there is a need to shift from this linear urban metabolism to a circular metabolism in which N and P from domestic waste and wastewater are reused in agriculture.

Review article: the role of gastrointestinal hormones in the treatment of delayed gastric emptying in critically ill patients.

Background: Delayed gastric emptying limits the administration of enteral nutrition, leading to malnutrition, which is associated with higher mortality and morbidity. Currently available prokinetics have limitations in terms of sustained efficacy and side effects.

Aim: To summarise the mechanisms of action and to discuss the possible utility of gastrointestinal hormones to prevent or treat delayed gastric emptying in critically ill patients.

[Persistent fever of unknown origin in two young infants caused by the atypical form of Kawasaki disease].

Two previously healthy infants, a boy and a girl aged 3 and 4 months, respectively, were admitted for fever of unknown origin with laboratory results indicating an inflammation. The boy presented with vomiting, pyuria, anaemia, and thrombocytosis. The girl presented with irritability, erythema and diarrhoea.

Right ventricular dysfunction and pulmonary valve replacement after correction of tetralogy of Fallot.

Background: Correction of tetralogy of Fallot often leads to pulmonary regurgitation, sometimes warranting pulmonary valve replacement, for which indications and timing to achieve optimal results are not yet clear. This retrospective study describes follow-up and reinterventions in our tetralogy of Fallot population.

Methods: Review of all consecutive patients operated on for tetralogy of Fallot between 1977 and 2000 was conducted.

Right ventricular dysfunction and the role of pulmonary valve replacement after correction of tetralogy of Fallot.

Background: Correction of tetralogy of Fallot (ToF) often leads to pulmonary regurgitation, sometimes warranting pulmonary valve replacement (PVR), for which the indications and timing to achieve optimal results are not yet clear. This retrospective study describes follow-up and reinterventions in our ToF population.

Methods: Review of all consecutive patients operated for ToF between 1977 and 2000.
