Importance: Allergic diseases are prevalent in childhood. Early exposure to medications that can alter the microbiome, including acid-suppressive medications and antibiotics, may influence the likelihood of allergy. Objective: To determine whether there is an association between the use of acid-suppressive medications or antibiotics in the first 6 months of infancy and development of allergic diseases in early childhood. Design, Setting, and Participants: A retrospective cohort study was conducted in 792 130 children who were Department of Defense TRICARE beneficiaries with a birth medical record in the Military Health System database between October 1, 2001, and September 30, 2013, with continued enrollment from within 35 days of birth until at least age 1 year...

BACKGROUND: Cinnamyl alcohol is considered to be a prohapten and prehapten with cinnamal as the main metabolite. However, many individuals who are allergic to cinnamyl alcohol do not react to cinnamal. Sensitizing epoxides of cinnamyl alcohol and cinnamal have been identified as metabolites and autoxidation products of cinnamyl alcohol. OBJECTIVE: To investigate the clinical relevance of contact allergy to epoxycinnamyl alcohol and epoxycinnamal. METHODS: Irritative effects of the epoxides were investigated in 12 dermatitis patients...

Allergic contact dermatitis commonly affects patients with chronic venous leg ulcers and can contribute to impaired wound healing. Many allergens have been identified, and despite the use of advanced dressings, the incidence of allergy has remained high. We discuss an unusual presentation of allergic contact dermatitis in a patient with a chronic wound. The patient's history was consistent with a recurrent venous leg ulcer, but on this occasion, the wound continued to deteriorate despite optimal treatment. This prompted further investigation, which included patch testing...

BACKGROUND: Historically, allergic contact dermatitis caused by hexavalent chromium [Cr(VI)] in cement was the most common cause of invalidity attributable to skin disease in Sweden. Since the legislation to reduce Cr(VI) in cement was introduced in 1989, we rarely see allergic contact dermatitis caused by cement. OBJECTIVES: To examine the frequency of contact allergy to Cr(VI) in southern Sweden in 2005-2014. METHODS: We investigated the occurrence of positive reactions to potassium dichromate 0...

In the past decade, new diabetes technologies, including continuous glucose monitoring (CGM) systems, support patients with diabetes in their daily struggle with achieving a good glucose control. However, shortly after the first CGM systems appeared on the market, also the first concerns about adverse skin reactions were raised. Most patients claimed to suffer from (sometimes severe) skin irritation, or even allergy, which they related to the (acrylate-based) adhesive part of the device. For a long time the actual substance that caused these skin reactions with, for example, the Flash Glucose Monitoring system (iscCGM; Freestyle® Libre) could not be identified; however, recently Belgian and Swedish dermatologists reported that the majority of their patients that have developed a contact-allergic while using iscCGM react sensitively to a specific acrylate, that is, isobornyl acrylate (IBOA)...

Methylisothiazolinone (MI) is commonly used as a preservative in personal care products and is a frequent cause of allergic contact dermatitis. We present a patient with allergic contact dermatitis caused by MI in hair care products and discuss this allergen to bring attention to this common cause of contact dermatitis, and to highlight its frequent use in hair care products. If allergy to MI is suspected, testing should be performed to this individual preservative, as testing solely for the combination preservative, methylisothiazolinone/methylchloroisothiazolinone (Kathon CG®), may miss many cases of MI allergy...

Facial dermatitis (FD) is a common problem encountered in clinical practice. It effects patients' self-esteem and quality of life. Mild reactions such as itching, pricking, dryness can occur in more than 10% of patients[1]. Recurrence is common in FD. The cause of FD is often difficult to determine. Metals, cosmetics, air pollution and physical factors such as wind or changes in temperature and humidity in the environment may all contribute to the development of FD[2]. Patch test is useful in establishing the identification of FD[1,2]...

BACKGROUND: Prenatal maternal stress may influence offspring's atopic risk through sustained cortisol secretion resulting from activation of the hypothalamic-pituitary axis (HPA), leading to Th2-biased cell differentiation in the foetus. We undertook a systematic review and meta-analysis investigating the relationship between prenatal maternal psychosocial stress and risk of asthma and allergy in the offspring. METHODS: We searched 11 electronic databases from 1960 to 2016, searched the grey literature and contacted experts in the field...

Basophils have been recently recognized to play important roles in type 2 immune responses during allergies and parasitic infection, largely due to the development of novel tools for the in vivo study of these cells. As such, the genetically-engineered MCPT8DTR mouse line has been used to specifically deplete basophils following treatment with diphtheria toxin (DT). In this study, we showed that DT-injected MCPT8DTR mice exhibited a striking decrease of eosinophils and neutrophils in skin when subjected to a hapten fluorescein isothiocyanate (FITC)-induced allergic contact dermatitis (ACD) experimental protocol...

Immunoglobulin E (IgE) is involved in the onset of allergic reaction, and the suppression of IgE production leads to alleviation of allergic symptoms. We found that mango peel ethanol extract (MPE) significantly suppresses IgE production by human myeloma cell line U266 cells, suggesting that MPE has an anti-allergic effect by inhibiting the production of IgE. Although mangiferin is contained in mango, which suppresses IgE production by U266 cells, it was not contained in MPE. We investigated the suppressive effect of MPE in 2,4-dinitrofluorobenzene (DNFB)-induced allergic contact dermatitis model mice...
