Discrepancies in the management of acquired cold contact urticaria: Results of a French-speaking urticaria experts questionnaire survey.

Acquired cold contact urticaria (ACU) is a putatively serious condition, because of the risk of anaphylactic shock whenever patients are massively exposed to cold atmosphere/water, raising the question of the prescription of an "emergency kit" with oral antihistamines and epinephrine auto-injector. We performed an online survey to evaluate how French-speaking urticaria experts manage ACU. According to the 2016 consensus recommendations on chronic inducible urticarias, all the participants perform at least 1 of the available provocation tests and 84.

Therapeutic patient education improves knowledge and skills for patients with chronic spontaneous urticaria.

Therapeutic patient education (TPE) allows patients to better understand their disease and cope with treatment. TPE programmes have not yet been evaluated for chronic spontaneous urticaria (CSU). To investigate the cognitive and behavioural impact of TPE on CSU patients.

[DRUGS-INDUCED URTICARIA AND ANGIOEDEMA].

Drug-induced urticaria and/or angioedema is a frequent issue encountered in family medicine. A specific collection of the anamnesis and of the general context is very important to appreciate the involved mechanism, allergic or not, and potential cofactors. If in doubt about an allergic mechanism, tests will be conducted, mostly under a hospital setting.

[Histaminergic angioedema and chronic urticaria].

Most angioedemas are histaminergic and correspond to deep urticarial swelling. Recurrent histaminergic angioedema led to the diagnosis of chronic urticaria, even when there are no superficial associated hives. Chronic urticaria is a benign disease, and autoimmune in 40 % of cases.

Chronic spontaneous urticaria is not an allergic disease.

The links between chronic urticaria, IgE sensitization and allergy have been much discussed but little studied. We investigated IgE sensitization and allergy in 128 adult chronic urticaria patients during 2006-2008. During a one-day hospitalisation, the patients answered a standardized questionnaire and underwent blood serum analysis, physical tests and skin prick-tests.

Influence of measles vaccination on the progression of atopic dermatitis in infants.

Atopic dermatitis (AD) is a chronic inflammatory skin disease, affecting 10-20% of children. Measles vaccination has been reported to have contradictory effects on incidence of AD in children. Therefore, we performed the first prospective, double-blind, placebo-controlled study to analyze the evolution of AD in infants after measles vaccination.

Generalized pustular psoriasis (Zumbusch): a French epidemiological survey.

A retrospective epidemiological survey of generalized pustular psoriasis (GPP) was carried out in France in 2005. 121 dermatological wards received a questionnaire concerning the patients treated in 2004. It related to demographic data, morbidity, mortality, failures and the therapeutic practices of each ward.

Generalized pustular psoriasis (von Zumbusch) following iatrogenic hypocortisolism.

Generalized pustular psoriasis can be triggered by hypocalcemia, pregnancy, stress and drugs but frequently has no obvious cause. We report a case which was only cured after treatment of iatrogenic adrenal axis suppression. A 41 year old woman had been suffering for nine months from a generalized pustular psoriasis which had occurred after a three week topical corticosteroid therapy of plaque psoriasis with 90 g of betamethasone dipropionate + 2% salicylic acid.
