Erythema is an abnormal redness of the skin due to dilation of the superficial capillaries of the skin causing inflammation. It can result from many different causes, diseases of the skin and some systemic diseases.
Simple erythema can be caused by cold, heat (as in contact with a heating pad or hot water bottle), or solar radiation. In its more severe forms it generally presents in one of two ways: (1) Erythema multiforme is an allergic (hypersensitivity) inflammatory reaction, often associated with herpes virus infections. (2) Erythema nodosum is an allergic (delayed-hypersensitivity) reaction that results in the formation of tender, deep red bumps on the arms or legs, particularly on the shins. It is most often associated with infections, the use of oral contraceptives and inflammatory bowel disease (such as Crohn's disease). However, the actual cause is identified in only about 50% of cases. Risk factors include heredity, female sex, recent travel, or a recent history of bacterial or fungal infection.
The Encyclopedia of World Problems and Human Potential is a unique, experimental research work of the Union of International Associations. It is currently published as a searchable online platform with profiles of world problems, action strategies, and human values that are interlinked in novel and innovative ways. These connections are based on a range of relationships such as broader and narrower scope, aggravation, relatedness and more. By concentrating on these links and relationships, the Encyclopedia is uniquely positioned to bring focus to the complex and expansive sphere of global issues and their interconnected nature.
The initial content for the Encyclopedia was seeded from UIA’s Yearbook of International Organizations. UIA’s decades of collected data on the enormous variety of association life provided a broad initial perspective on the myriad problems of humanity. Recognizing that international associations are generally confronting world problems and developing action strategies based on particular values, the initial content was based on the descriptions, aims, titles and profiles of international associations.
Non-profit, apolitical, independent, and non-governmental in nature, the UIA has been a pioneer in the research, monitoring and provision of information on international organizations, international associations and their global challenges since 1907.
