Idiosyncrasy is a condition in which there is a strange (usually violent) reaction to the ingestion of certain substances that do not cause most people have no pathological phenomena. Most often attack idiosyncrasies cause food substances (fish, some berries, eggs), drugs (see Drug), chemicals (bromine, iodine), the pollen of some plants, organic paints, etc. Attack idiosyncrasies develops rapidly after exposure to the organism causing its matter and is accompanied by swelling of the skin and mucous membranes, eczema, hives, runny nose, and in more severe cases, shortness of breath, astmatoidnogo state and gastrointestinal disorders. The duration of the attack from several hours to several days.
If any attack idiosyncrasies recommended antihistamines, such as diphenhydramine, pipolfen, suprastin. In the future, it should avoid contact with substances that can cause the idiosyncrasy.
Although idiosyncrasy and considered to be a private manifestation of Allergy (see), but has a number of features that contradict this assumption. So, idiosyncrasy usually appears at the first entry of the agent into the body, i.e. without prior sensitization of the body, does not cause subsequent desensitization and often occurs under the action of non-protein substances of nature and therefore does not have antigenic properties. However, on this basis, it is still impossible to prevent allergic nature idiosyncrasy, as it is possible that sensitization to one or another agent or can be obtained from the mother through the placenta or milk), or can happen in life, but to escape attention.
