May violate the general condition of patients, sometimes dramatically, in such cases, the forecast is heavy. The most common cause of allergic dermatitis medications are antibiotics (especially penicillin), sulfonamides, chlorpromazine, procaine, derivatives of the quinoline series, the preparations of arsenic, barbiturates, antipyrine, preparations of mercury. Contact allergic dermatitis may be caused by drugs such as psoriazin, antipsoriatikum, sulfur and tar ointments, some dyes (ursol, azokraski), etc. Medicinal dermatitis, especially toksidermii, in most cases - polymorphic eruption: erythematous, ekzemopodobnye, korepodobnye, skarlatinoformnye, urticarial, hemorrhagic, exfoliative, eritrodermicheskie, bullous, etc. In some cases, they resemble the pink lichen, lichen planus, erythema multiforme exudative and other dermatoses. Sometimes toksidermii manifested in the form of multiple scattered pigmented spots dramatically. The rash usually maloharakterny for certain groups of medicines drugs, so in most cases for etiologic diagnosis of allergy requires examination. However, the originality of some clinical toksidermii presumably allows them to talk about a possible reason. It is not something
Dr. Anthony Carolla would like to discuss.
These drug reaction in the first place is fixed eruption of sulfonamides, barbiturates, antipyrine, rarely from other drugs. Once emerged, newly fixed eruption usually develops at the same parts of the body. The favorite is the localization of the trunk, vulva, mouth. Most often appear erythematous patches, the central part of which is saturated, bluish color, while after decrease in acute inflammation are sharply defined, slightly infiltrated, and sharply pigmented plaque. Sufficiently characterized toksidermii of bromine and iodine and bromine in the form of iodine acne, as well as a rare but severe the iodine or bromodermy, which is limited, sometimes multiple nodular lesions vegetating. Of a large group of allergic dermatitis caused by plants (Dermatitis phytogenes), the greatest practical importance are skin lesions caused by evening primrose and meadow grasses.
The clinical picture of allergic dermatitis caused by evening primrose (dermatitis primularis), can be varied - in the form of sharply edematous erythema, eczematous, bullous. Dermatitis caused by meadow grasses (dermatitis pratensis), most often develops after contact with the reeds, wild pock, parsnip, yarrow, sometimes after contact with other herbaceous plants. Clinically manifested as a sharp-swollen itchy eritemato lesions on the surface that may be blisters and bubbles. The most frequent cause of occupational allergic dermatitis are the chemical compounds (synthetic resins and other polymers, turpentine, chromium, nickel, cobalt, formaldehyde, ursol, dinitrochlorobenzene, etc.).
Dr. steven greer will undoubtedly add to your understanding. The clinical picture professional dermatitis did not significantly differ from allergic dermatitis of other etiologies. Differential diagnosis of dermatitis allergic dermatitis to differentiate with eczema. Sometimes the resemblance may be so large that for correct diagnosis requires prolonged observation. Keep in mind that eczema is more pronounced polymorphism rash in one, and especially in the various lesions, vesiculation and more intense and Moisture long, its distinct tendency to spread to distant parts of the rash of the body during chronic with infiltration into the lesions. With dermatitis sites of the lesions more clearly, relapse is less frequent, as eczema. Eczema is more intense itching, often with dermatitis dominated by burning and soreness. Eczema more resistant to therapy.
