Chronic spontaneous urticaria remission definition and therapy stepping down: World Allergy Organization position paper.

Background: There is no global agreement on the definition of chronic spontaneous urticaria (CSU) remission.

Objective: Our aim was to generate a consensus for clinical definitions of CSU-related terms focused on remission.

Methods: The World Allergy Organization Urticaria Committee systematically reviewed current available longitudinal articles.

Severely compromised supply of patch test allergens in Europe hampers adequate diagnosis of occupational and non-occupational contact allergy. A European Society of Contact Dermatitis (ESCD), European Academy of Allergy and Clinical Immunology (EAACI), European Academy of Dermatology and Venereology (EADV) task forces 'Contact Dermatitis' and 'Occupational Skin Disease' position paper.

Patch testing is the only clinically applicable diagnostic method for Type IV allergy. The availability of Type IV patch test (PT) allergens in Europe, however, is currently scarce. This severely compromises adequate diagnostics of contact allergy, leading to serious consequences for the affected patients.

Medical devices in allergy practice.

Medical devices provide people with some health benefits in terms of diagnosis, prevention, treatment, and monitoring of disease processes. Different medical specialties use varieties of medical devices more or less specific for them. Allergology is an interdisciplinary field of medical science and teaches that allergic reactions are of systemic nature but can express themselves at the level of different organs across the life cycle of an individual.

In vivo diagnosis with purified tropomyosin in mite and shellfish allergic patients.

Background: Tropomyosin is the most studied shellfish allergen and has been involved in cross-reactivity among different invertebrates (crustacean, mollusks, mites, insects, and nematodes).

Objective: To determine the relevance of tropomyosin in mite- and shellfish-sensitized patients using tropomyosin skin testing.

Methods: Patients were divided into 3 groups: group M included mite allergic patients (ie, individuals with respiratory symptoms and a positive result on skin prick testing [SPT] to house dust mites), group S included shellfish allergic patients (ie, individuals who reported symptoms with shellfish), and group MS included mite- and shellfish allergic patients (ie, individuals who simultaneously fulfilled the inclusion criteria for groups M and S).

Prevalence of sensitization to Cannabis sativa. Lipid-transfer and thaumatin-like proteins are relevant allergens.

Background: Although allergy to Cannabis sativa was first reported over 40 years ago, the allergenicity has scarcely been studied. The objectives of this study were to investigate the frequency of sensitization to this plant, to analyze the clinical characteristics and allergenic profile of sensitized individuals and to identify the allergens involved.

Methods: Five hundred and forty-five individuals in Spain attending allergy clinics with respiratory or cutaneous symptoms underwent a skin-prick test (SPT) with C.

Allergenicity of casein containing chalk in milk allergic schoolchildren.

Background: Nondietary exposure to milk proteins may be a risk for children who do not outgrow milk allergy by school age.

Objective: To study the allergenicity of casein containing chalk.

Methods: A 6-year-old, milk allergic child developed asthma and rhinoconjunctivitis while in school.

Recently introduced foods as new allergenic sources: sensitisation to Goji berries (Lycium barbarum).

Goji berries (GB) have been introduced in Western diet. Preliminary reports have demonstrated its allergenic capacity. The objectives of the study were to investigate the frequency of sensitisation and the allergens involved.

Identification and quantification of tomato allergens: in vitro characterization of six different varieties.

Background: The prevalence of sensitization to tomato has been estimated in 6.5% in a Mediterranean population.

Objectives: To characterize the allergenic profile of 6 commonly ingested varieties of tomato and to identify and quantify the most representative allergens.

In vitro cross-reactivity between tomato and other plant allergens.

Background: Cross-reactivity among fruits and different pollen and fruit species has been extensively reported.

Objectives: To investigate the in vitro cross-reactivity between tomato and pollen, fruit, and latex extracts and to identify the proteins involved.

Methods: A serum pool was prepared from 18 individuals residing on the Spanish Mediterranean coast (9 men and 9 women; mean [SD] age, 27.

Sensitization and allergy to Cannabis sativa leaves in a population of tomato (Lycopersicon esculentum)-sensitized patients.

Background: Cases of allergy to Cannabis sativa have occasionally been reported, but both the allergenic profile and eventual cross-reactivity pattern remain unknown.

Objective: To analyze the allergenic profile of a population of patients from Spain sensitized to C. sativa and to characterize the C.

Mud bath dermatitis due to cinnamon oil.

A case of long-lasting, extensive eczematous and bullous dermatitis affecting exposed areas (arms and legs), beginning within 24 hr after having a mud bath with cinnamon essential oil in a spa, in a 74-year-old woman, is reported. Patch tests with the GEIDC standard battery and the dental battery (including clove essence and eugenol), cinnamon essence and its components were carried out 5 years later. Fragrance mix, cinnamon essence, eugenol, cinnamic alcohol and cinnamic aldehyde yielded a positive result.
