Aquagenic cutaneous disorders Authors: Wang F1, Zhao YK2, Luo ZY1, Gao Q1, Wu W3, Sarkar R4, Luo DQ2. 1 Department of Dermatology, The First Affiliated Hospital, Sun Yat-sen University, Guangzhou, China. 2 Department of Dermatology, The Eastern Hospital of The First Affiliated Hospital, Sun Yat-sen University, Guangzhou, China. 3 Department of Dermatology, Affiliated Hospital of Guangdong Medical University, Zhanjiang, China. 4 Department of Dermatology, Maulana Azad Medical college and LNJP Hospital, New Delhi, India. Abstract Aquagenic cutaneous disorders, which include aquagenic urticaria, aquagenic pruritus, and aquagenic acrokeratoderma, are a group of rare diseases characterized by skin lesions or discomfort induced by brief contact with water. Aquagenic urticaria is characterized by pruritic wheals that occur at the sites of water contact, either immediately or within minutes, and disappear within 30-60 min after water removal. Aquagenic pruritus presents

Capítulo A2.  Allergens and the Allergenic Composition of Source Materials Authors: Ronald van Ree, Rob C. Aalberse Abstract:  Many different types of proteins are allergenic. The context of a protein may be a major determinant for its allergenicity. Some IgE inducers are not really allergens at all because they don’t induce symptoms. This negatively impacts specificity of diagnostic tests, certainly of extract-based tests but also still of molecular tests. Allergen extracts are imperfect but not yet obsolete. Molecular sensitization profiles: potential biomarkers for disease phenotypes and progression The initial response to an allergen source is possibly characterized by IgE antibodies to one or two “initiator” allergens.

The diagnostic value of APT for food allergy in children: a systematic review and meta-analysis. Authors: Luo Y1, Zhang GQ1, Li ZY1. 1 Ministry of Education Key Laboratory of Child Development and Disorders, Key Laboratory of Pediatrics in Chongqing, Chongqing International Science and Technology Cooperation Center for Child Development and Disorders, Department of Gastroenterology, Children's Hospital of Chongqing Medical University, Chongqing, China. Abstract BACKGROUND: The role of atopy patch test (APT) in the diagnosis of food allergy (FA) remains largely controversial. In our meta-analysis, we aimed to evaluate the accuracy of APT for diagnosing FA in children. METHODS: Pubmed, Embase and Cochrane Library were searched for studies regarding the diagnostic value of APT for FA in children compared to oral food challenge (double-blind placebo-controlled food challenge and/or open food challenge). The last search was conducted on November 11, 2017. Two revie

Capítulo A1: Alergollogy from extracts to molecules: Integrating tadition with innovation. Authors : Paolo Maria Matricardi, Jörg Kleine-Tebbe, Hans Jürgen Hoffmann, Rudolf Valenta, Markus Ollert.  Abstract:  The transition from allergen extracts to molecules for the diagnostic work-up of IgE mediated reactions/diseases has great potential, but requires detailed knowledge and intelligent interpretation Diagnostic algorithms traditionally start with the history (“top-down”), followed by skin tests, then IgE assays adding allergen molecules for “component-resolved diagnosis” (CRD) Novel diagnostics invert the test order (“bottom-up”) and start with a multiplex (i.e. microarray-based) IgE assay and many components. Then the history is reviewed for concordance to establish a broad CRD Combining both strategies, “top-down” and “bottom-up”, creates a “U-shaped” sequence. Traditional diagnostic work-up can thus be expanded by a broad screening for IgE-binding molecules unfoldi

OBJECTIVE: The aim of this review was to systematically evaluate the published evidence of any psychiatric disorders that may coexist with chronic urticaria (CU) and any effect psychiatric interventions may have on CU. METHODS: Following the Cochrane guidance, we conducted a systematic literature search using web-based search engines provided by PubMed (for Medline database), Google Scholar and Scopus for studies that have investigated the existence of psychiatric comorbidity in patients with CU.

The first year of treatment predicts the prognosis of asthma over 25 y-A prospective study. Authors:  Kauppinen R1, Vilkka V1, Sintonen H2, Hedman J1 . 1 Pulmonary Department, South Karelia Central Hospital, Lappeenranta, Finland. 2 Department of Public Health, University of Helsinki, Helsinki, Finland. Abstract: BACKGROUND: An investigator-driven, real-life follow-up study of adult-onset steroid-naïve, newly diagnosed asthma (162 patients) to investigate the treatment results over the 25-year course of the disease and whether the first treatment year's forced expiratory volume in one second (FEV1 ) predicts the long-term prognosis. METHODS: Eighty-three per cent of the 133 living patients participated in the 25-year examinations. At this visit, basic asthma examinations including lung function, as well as questionnaires for health-related quality of life (HRQoL), GINA and the Asthma Control Test, were used for evaluation. The use of medication and remission
