Climbing the ladder: a step by step approach to international guidelines for water recycling.

Given the pressures on the world's freshwater resources, recycled water is a valuable resource. Recycled water can increase the reliability of water supply because it is an independent source of water. Water recycling requires effective measures to protect public health and the environment. In the absence of comprehensive international guidelines, different countries have developed different approaches to managing water recycling depending on the understanding of the health risks, their individual economic circumstances, and affordability. Approaches vary between high technology/high cost/low risk and low technology/low cost/controlled risk. Furthermore, differences occur between countries and within individual countries. Inconsistencies can often be traced to lack of a unified scientific position on health effects. These inconsistencies increase public concerns about health risks and may give rise to conservative controls on responses to water recycling projects that some countries may be unable to afford. In this paper, an international panel of authors discusses how the different water recycling approaches might be linked together into international water recycling guidelines. These guidelines would incorporate a uniform approach to assessing hazards and risks while providing flexibility for individual countries to vary requirements to suit local circumstances of affordability and risk. The authors propose a framework of guidelines in which individual countries can progressively improve recycled water quality as lower risk levels become more affordable. The authors argue that a uniform international approach will result in a number of benefits including a better focus on risk management, better targeted research and development efforts and greater public confidence in water recycling. The authors invite discussion on the concepts put forward in the paper.

One step back and one, possibly two, steps forward. The different approaches to Parkinson's disease.

Parallel approaches to the development of medical treatment often experience advances in one technology sector and simultaneous setbacks in others. The potential role of medical devices and biomaterials in the treatment of neurological conditions such as Parkinson's Disease is discussed here together with the contrast between the role of devices in tackling the consequences of disease and that of drugs and cell therapies that aim to cure it.

Applying split-thickness skin grafts: a step-by-step clinical guide and nursing implications.

Wounds in the lower extremities represent a complex medical dilemma and a significant financial burden on the healthcare system. Often, skin grafts and flaps must be incorporated into the treatment of complex defects. Wound management has developed from a multidisciplinary to a collaborative forum, blurring treatment lines among the specialties. Various clinicians and specialists are playing an increasingly larger role in the healing algorithm of wounds in the lower extremities, including the application of skin grafts. This allows the plastic surgeon to deal with the more complex free flaps and microscopic surgical procedures. A patient's status following skin grafting can be an issue in many nursing care environments. This paper provides a pictorial review of a reliable split-thickness skin graft technique that fosters imbibition and inosculation. The points relevant to nursing care include nursing implications (for the graft and donor site), complications, and what to expect in patients who have undergone the procedure.
