Angular cheilitis and glossitis (inflammation of the tongue). It is not completely understood how iron deficiency causes AC, but it is known that it causes a degree of immunocompromise (decreased efficiency of the immune system) which may in turn allow an opportunistic infection of candida. Vitamin B2 deficiency (ariboflavinosis) may also cause AC, and other conditions such as redness of mucous membranes, magenta colored glossitis (pink inflammation of the tongue). Vitamin B5 deficiency may also cause AC, along with glossitis, and skin changes similar to seborrhoeic dermatitis around the eyes, nose and mouth.

American Board of Disaster Medicine Specialists (AAPS) commissioned an expert panel to undertake a scholarly review of the literature and survey the recognized experts in disaster management, emergency management, medical contingency planning, emergency medicine, public health, disaster behavioral health and military medicine to determine if such a unique body of knowledge and skills existed. By February 2004 it was determined that the majority of experts, supported by the available literature, agreed that there is a unique body of core knowledge and skills to define the specialty of Disaster Medicine and a broader body of knowledge needed by all healthcare practitioners responding to a disaster event.
