Preparing children and young people for stoma surgery.

There is little published literature regarding children and young people with stomas and their preoperative care. Research in adults reveals negative psychosocial consequences, but the perceptions of children and young people may be different, depending on the reason for the stoma formation and the degree of involvement in decisions. Post-operative problems and later negativity can be minimised with informed decision making and partnership from the outset between the healthcare team, parents and child. Preparation approaches known to be successful for other forms of surgery can be adapted to prepare the child/young person for stoma surgery.

Clinical practice guidelines: moving into the 21st century.

Clinical practice guidelines affect every aspect of healthcare. Practitioners, third-party payors, regulatory bodies, governments, and accrediting agencies increasingly use these guidelines, which are developed by a wide variety of organizations. The majority of guidelines are based on consensus and a nonsystematic literature review, but some, including those developed by the Agency for Health Care Policy and Research, are evidence based. Both types of guidelines have distinct advantages and limitations. Consensus-based guidelines are less time consuming to develop but may lack crucial information and result in a wide variety of outcomes; whereas, the type of evidence used to develop strength-of-evidence ratings for evidence-based guidelines may result in ambiguous recommendations and cause ethical concerns. Outcomes research on the use of guidelines and issues related to their timeliness need to be addressed. Studies that include a wide variety of outcome indicators and care variables and contributions of clinicians are needed to develop practice guidelines that are clinically useful and improve patient care.

Medical applications of copolyester elastomer films.

Medical dressings and devices are now required to fulfil a number of demands. These include preventing the entry of bacteria to the wound and improving the healing rate. Copolyester elastomers (COPEs) can play a significant role in providing these benefits because they can be blended to offer a range of characteristics. In this article, the author discusses the mechanical and physical properties of COPEs and discusses how these properties have been utilized, and their potential for future development.

An attempt for the application of the basic Law of Psychophysics (Fechner-Stevens Law) in the domain of visceral stimuli in humans.

The validity of the basic Law of Psychophysics proposed originally by Fechner and revised by Stevens had been tested in the domain of visceral perception. The experiments were carried out on six adult colonostomy patients. The distension of the sigmoid colon (the phi-value of the Fechner-Stevens equation) had been undertaken by the aid of a rubber balloon inserted into the intestinal stoma orifice and controlled by a computerized pneumatic system. The tracking of sensations of "gut-feelings" by the subjects (the psi-value of the Fechner-Stevens equation) had been made possible by applying the subjects' manipulation of a sliding potentiometer of a Visual Analogue Scale (VAS-device). The results seem to prove the extension of the validity of the Fechner-Stevens power equation to the field of visceral perception.
