1. What can we learn from measuring IgE to allergens and allergen components in tropical and subtropical settings in Brazil?
Abstract Objective This narrative, non-systematic review provides an update on the genetic aspects of the SARS-CoV-2 virus and its interactions with the human genome within the context of COVID-19. Although the main focus is on the etiology of this new disease, the genetics of SARS-CoV-2 impacts prevention, diagnosis, prognosis, and the development of thera

2. IAO Systematic Review Award 2020
Abstract Background: Cosmetics are part of the daily life of the population, and their use can lead to allergic contact dermatitis. Objectives: To assess the profile of patients diagnosed with allergic contact dermatitis to cosmetics treated at a referral center for 13 years, as well as the characteristics of the clinical picture and allergens involved.

4. Sociodemographic and clinical profile of patients with occupational contact dermatitis seen at a work-related dermatology service, 2000 - 2014
Abstract: BACKGROUND: Occupational dermatoses are common, especially contact dermatitis. Epidemiological studies on these dermatoses are scarce in Brazil and they are necessary as part of the public policy to protect workers' health. OBJECTIVES: To identify sociodemographic and clinical profile of patients with occupational contact dermatitis seen between

5. Evaluation of the presence of allergens in children's products available for sale in a big city
Abstract: Children's products are considered safe by the general population and doctors. Labels with terms such as "hypoallergenic" or "dermatologically recommended and tested" denote trust and credibility with the idea that they can be used by any individual. Patients with allergic contact dermatitis may be sensitive to allergens present in any product, inc

6. Homology modeling and epitope prediction of Der f 33
Dermatophagoides farinae (Der f), one of the main species of house dust mites, produces more than 30 allergens. A recently identified allergen belonging to the alpha-tubulin protein family, Der f 33, has not been characterized in detail. In this study, we used bioinformatics tools to construct the secondary and tertiary structures and predict the B and T cel

7. Innate immunity and effector and regulatory mechanisms involved in allergic contact dermatitis
Abstract: Skin's innate immunity is the initial activator of immune response mechanisms, influencing the development of adaptive immunity. Some contact allergens are detected by Toll-like receptors (TLRs) and inflammasome NLR3. Keratinocytes participate in innate immunity and, in addition to functioning as an anatomical barrier, secrete cytokines, such as TN

8. Orofacial granulomatosis and diet therapy: a review of the literature and two clinical cases
Abstract: Orofacial granulomatosis is a nonspecific term that contains a wide variety of granulomatous entities, which share a clinical and histopathological presentation. It manifests as persistent or recurrent orofacial swelling, amongst other findings. Idiopathic orofacial granulomatosis, characterized by an absence of systemic granulomatous disease, is a

9. Nickel, chromium and cobalt: the relevant allergens in allergic contact dermatitis. Comparative study between two periods: 1995-2002 and 2003-2015
Abstract: Background: Metals are common agents of allergic contact dermatitis, occupational or not, with decreasing incidence over the last years in some countries that have regulated the amount of nickel in objects. Objectives: To analyze and compare with previous studies the profile of metal sensitization between 2003-2015. Methods: Patients who underwe

10. Sensitization to cat allergen and its association with respiratory allergies: cross-sectional study
ABSTRACT Cats are a significant source of allergens that contribute towards worsening of allergic diseases. The aim of this study was to investigate the association between sensitization to cat allergens and allergic respiratory diseases.This was an observational retrospective study based on the skin pricktests results of patients at a tertiary-level hospita

11. Nickel exposure from keys: a Brazilian issue
Abstract: Keys are a significant source of exposure to metal allergens and can be a relevant problem for nickel-allergic individuals. This study aimed to perform nickel and cobalt spot testing among the 5 most common Brazilian brands of keys. Among the tested keys, 100% showed positive result to nickel spot test, 83,3% presented strong positive reaction. 50%

12. Cloning, structural modelling and characterization of VesT2s, a wasp venom hyaluronidase (HAase) from Vespa tropica
Abstract Background: Wasp venom is a complex mixture containing proteins, enzymes and small molecules, including some of the most dangerous allergens. The greater banded wasp (Vespa tropica) is well-known for its lethal venom, whose one of the major components is a hyaluronidase (HAase). It is believed that the high protein proportion and activity of this e
