Learners' Knowledge of Environmental Education in Selected Primary Schools of the Tshwane North District, Gauteng Province.

This study focused on determining the level of environmental education knowledge and skills among primary school learners in South Africa, under the National Curriculum Statement Grades R-12. Environmental education is important in the promotion of sustainable environmental conservation and reducing negative effects, which are caused by adverse climatic conditions. We used a qualitative approach for data collection from eight primary schools located in the North Tshwane District of Gauteng province, through interviews and observations.

A new dynamic six degrees of freedom disc-loading simulator allows to provoke disc damage and herniation.

Purpose: The cause of disc herniation is not well understood yet. It is assumed that heavy lifting and extreme postures can cause small injuries starting either in the inner anulus or from the outside close to the endplate. Such injuries are accumulated over years until its structure is weakened and finally a single loading event leads to a sudden failure of the last few intact lamellae.

Drug-related emergency department visits by elderly patients presenting with non-specific complaints.

Background: Since drug-related emergency department (ED) visits are common among older adults, the objectives of our study were to identify the frequency of drug-related problems (DRPs) among patients presenting to the ED with non-specific complaints (NSC), such as generalized weakness and to evaluate responsible drug classes.

Methods: Delayed type cross-sectional diagnostic study with a prospective 30 day follow-up in the ED of the University Hospital Basel, Switzerland. From May 2007 until April 2009, all non-trauma patients presenting to the ED with an Emergency Severity Index (ESI) of 2 or 3 were screened and included, if they presented with non-specific complaints.

Diuretic use, RAAS blockade and morbidity in elderly patients presenting to the Emergency Department with non-specific complaints.

Questions Under Study: Up to 20% of elderly patients present to the emergency department (ED) with non-specific complaints (NSC), such as "generalised weakness", the majority suffering from serious conditions requiring timely intervention. Little is known about the use and influence of diuretics and renin-angiotensin-aldosterone (RAAS) blockade on morbidity in those patients. The hypothesis was tested that the use of diuretics and RAAS blockade could be associated with an increased incidence of serious conditions in those patients.
