ESSCA – (i.e., European Surveillance System on Contact Allergies) Objective: Contact allergy is a frequent condition (with up to 20% of the general population affected), and its clinical manifestation – allergic contact dermatitis (incidence approximately 7 per 1000 per year)- has considerable socioeconomic impact. Recommendations concerning primary prevention must be founded on sound scientific knowledge concerning occurrence of allergen exposures in the population. To provide such data on a European scale, the expert network ESSCA has been conceived. The aim of ESSCA is the continuous analysis (surveillance) of pooled data for different purposes. This includes internal quality control, which is both a prerequisite, and an outcome of this multicentre activity. Furthermore, international comparisons which reflect the effects of a wider than strictly national allergen exposure variation, time-trend analyses, and subgroup analyses are performed, including the possible occurrence of known allergens in new exposure contexts. These analyses shall provide a valuable starting point for lowering the incidence of contact allergies. For industry, such analyses can serve the purpose of post marketing surveillance of product safety. *

Monounsaturated fatty acids have only one double or triple bond per molecule and are found as components of fats (triglycerides) in such foods as fowl, almonds, pecans, cashew nuts, peanuts, and olive oil. Polyunsaturated fatty acids have more than one double or triple bond per molecule and are found in fish, corn, walnuts, sunflower seeds, soybeans, cottonseeds, and safflower oil. Diets high in polyunsaturated fatty acids and low in saturated fatty acids have been correlated with low serum cholesterol levels in some study populations.**
