Systemic Symptoms

Erythema multiforme usually presents as an acute inflammatory reaction involving the skin and mucous membranes. Systemic symptoms and organ involvement also can occur. The disease is associated with many illnesses and drugs. A two-year-old child presented to the Family Practice Center with a probable codeine-induced episode of erythema multiforme. The patient had been treated with Actifed-C Expectorant for a suspected viral upper respiratory tract infection. The rash was characteristic of erythema multiforme, but there was no involvement of mucous membranes. The rash quickly abated after the discontinuation of the drug and the administration of hydroxyzine. A viral cause for the rash could not be ruled out. When erythema multiforme is precipitated by a particular drug, discontinuation of the offending agent is necessary. The rash should disappear quickly. Adjunctive use of antihistamines may offer some benefit for the patient. Systemic corticosteroids may be necessary for more severe cases.

Sodium lauryl sulfate is the most common surfactant used in the production of detergents, chloroprene rubber, plastics, artificial furs and in pharmaceutical industry. Sodium lauryl sulfate is a moderately hazardous substance when introduced into the stomach (DL50 for white mice and rats is in the range of 2086-2700 mg/kg), has a pronounced local irritant effect on the skin and mucous membranes of the eyes, has a skin-resorptive, sensitizing and pronounced cumulative effects. The threshold for acute inhalation action is set at 15,3 mg/m3 for changes in the function of the nervous system and irritating effects on the mucous membranes of the upper respiratory tract (an increase in the total number of cells in the nasal flushes).Recommended for approval tentative safe exposure level of sodium lauryl sulfate in the air of the working area is 0.2+ mg/m3 (aerosol).

Otitis media is mainly caused by upper respiratory tract infection and eustachian tube dysfunction. If external upper respiratory tract infection is not detected early in the middle ear, or an appropriate immune response does not occur, otitis media can become a chronic state or complications may occur. Therefore, given the important role of Toll-like receptors (TLRs) in the early response to external antigens, we surveyed the role of TLRs in otitis media. To summarize the role of TLR in otitis media, we reviewed articles on the expression of TLRs in acute otitis media (AOM), otitis media with effusion (OME), chronic otitis media (COM) with cholesteatoma, and COM without cholesteatoma. Many studies showed that TLRs 1–10 are expressed in AOM, OME, COM with cholesteatoma, and COM without cholesteatoma. TLR expression in the normal middle ear mucosa is absent or weak, but is increased in inflammatory fluid of AOM, effusion of OME, and granulation tissue and cholesteatoma of COM. In addition, TLRs show increased or decreased expression depending on the presence or absence of bacteria, recurrence of disease, tissue type, and repeated surgery. In conclusion, expression of TLRs is associated with otitis media. Inappropriate TLR expression, or delayed or absent induction, are associated with the occurrence, recurrence, chronicization, and complications of otitis media. Therefore, TLRs are very important in otitis media and closely related to its etiology.
