Cold urticaria can be classified into acquired and familial disorders, with an autosomal dominant inheritance. Idiopathic cold urticaria is most common type but the research of a cryopathy is necessary. Therapy is often difficult. It is essential that the patient be warned of the dangers of swimming in cold water because systemic hypotension can occur. H1 antihistamines can be used for treatment of cold urticaria but the clinical responses are highly variable. The combination with an H2 antagonists is more effective.

Our preliminary study on 6 cases of urticaria (5) and erythema (1) after use of ioxaglate and with positive search for ioxaglate-specific IgE (2.3 to 6.7) after coupling to Sepharose (Baldo and Fisher technique). The results of this technique are expressed with reference to a pool of serum of subjects who had no contact with these contrast products. The threshold of positivity was 2, the mean of the results from 10 subjects who were exposed lay between 1.37 +/- 0.42. Inhibition of specific IgE by ioxaglate was positive in 6 cases. In 2/3 cases inhibition by potassium iodide was also observed. Several published studies in favour of the existence of specific IgE of close specificity, the inhibitions of specific IgE presented were mostly only observed for the contrast product used. An hypothesis would be that the ionic molecules have a greater capacity to induce the synthesis of specific IgE than non-ionic molecules because of their affinity for carrier proteins.

All the molecules are divalent, carrying two NH4+ epitopes (quaternary ammonium ions), either structurally or after rapid in vivo protonization (vecuronium). The excellent overall performance of skin test makes them the golden standard for the diagnosis of anaphylactoid reactions. Techniques include intradermal tests and prick-tests. The current localizations are the forearm and the back. Positivity criteria are 3 mm for prick-tests. For IDTs, the criterium is the doubling of the size of the injection papula, when 0.02 to 0.04 ml is injected: 8 mm. The recommended concentrations are not falsely negative. Commercial concentrations can be tested by prick tests, except for mivacurium and atracurium tested of 1:10 dilution. A scale of concentrations is advised for IDT starting with 1:10,000, up to a normally non reactive concentration that is: 100 micrograms/ml (succinylcholine), 200 micrograms/ml (gallamine), 10 micrograms/ml (atracurium), 2 micrograms/ml (mivacurium), 200 micrograms/ml (pancuronium), 400 micrograms/ml (vecuronium), 1,000 micrograms/ml (rocuronium), 200 micrograms/ml (cis atracurium).

The prevalence of IgE-mediated food allergy is estimated at 3.24% of French population. Clinical pictures are varied: atopic dermatitis, urticaria and oedema, asthma, rhinitis, anaphylactic shock.

The role of risk factors on expression of food allergy is important: exercise, concomitant intake of alcohol, aspirin NAIDS, beta-blockers or converting enzyme inhibitors. The modifications of food habits and of food allergenicity by agro-alimentary technology, the consumption of novel foods and masked allergens explain the present aspects of food allergy. The role of intestinal flora and early diversification of food influence the acquisition of tolerance. The diagnosis of food allergy depends of the expert appraisement of the allergologist.
