Diabetes is a serious chronic disease that needs attention. Approximately 15% of al people with diabetes wil be affected by a foot ulcer during their lifetime.1 George Bernard Shaw Diabetic foot ulcers (DFUs) often co-exist with vascular insufficien-cy and are the major cause of gangrene and amputation in people with diabetes. Risk of developing diabetic foot ulcers is greatly in-creased by reduced sensation and blood pressure. Diabetic foot ulcers represent a huge risk to the patient's quality of life, escalating wound/infection management and costs, and account for a large proportion of al national healthcare budgets · Five-year recurrence rates of foot ulcers are 70%2 · Up to 85% of al amputations in relation to people with diabetes are preceded by a foot ulcer1-2 · People with diabetes with one lower limb amputation have a 50% risk of developing a serious lesion in the second limb within 2 years3 · People with diabetes have a 50% mortality rate in the 5 years fol owing the initial amputation4 It is possible to reduce amputation rates by 49-85% through a care strategy that combines prevention, the interprofessional diabetes care team, appropriate organisation, close monitoring and education.1 Pathway to clinical care How to prevent DFUs and clinical evidence Prevention and education "49-85% of all diabetic foot related problems are preventable." Diabetic foot ulcers Spraul, M., 2000.6 "This can be achieved through a combination of good foot care, provided by an interprofessional diabetes care team, and appropriate education for people with diabetes." Modified from Bakker, K. et al., 2005.1 "Education of patients, carers, and healthcare providers is an essential component of an effective, interprofessional team approach, …but effective systems and structures for screening, provision of chiropody and footwear, and prompt treatment when required must be in place." Modified from Spraul, M., 2000.6 "The most important aspects, for example, danger signs which require prompt action by the patient, should be summarized and repeated."Spraul, M., 2000.6 Evidence-based wound management "Successful diagnosis and treatment of patients with chronic wounds involve holistic care and a team approach. The integration of the work of an interprofessional care team that includes doctors, nurses and al ied health professionals with the Real life studies patient, family and caregivers offers an optimal formula for achieving wound resolution."Sibbald, R.G., et al, 2001.18 Prevention of ulcer formation An interprofessional team approach People with diabetes must inspect their feet regularly, or have a family member or care provider do it on their behalf. Daily inspection is the foundation of diabetic foot ulcer prevention. Al wounds and sores should be taken seriously early on.

Risk versus benefit of raw milk consumption Dominique Angèle VUITTON WHO Collaborating Centre; University of Franche-Comté; 25030 Besançon, France Background: the contradiction between "food safety" and biodiversity, high quality of products, sustainable development, and healthy life style. Dairy farmers and cheese producers are in the continuing process of answering the somewhat contradictory requirements of consumers for safe, high quality and diversified foods produced in sustainable conditions… at the lowest price. It has turned out that the legitimate requirements of safety from the consumer have eventually evolved in a burden of threats upon producers' activities, once they began being translated in tentative safety regulations. Within the past 10 years, the main concern of numerous producers, with little link with big dairy industry companies, has always been to provide food diversity through a traditional way of producing milk and cheese and to maintain biodiversity while reaching at the same time the very high quality and safety standards requested by the consumers. However, they now have the feeling that their way of doing is not supported in reality by the public policies and that the attitudes of experts and/or authorities may be sometimes quite contradictory.
