BACKGROUND In the latest decades, epidemiological studies on allergic disorders in children, including atopic dermatitis, rhinitis and asthma, demonstrated a continuous increase in prevalence. However, such studies are usually performed by questionnaires and, sometimes, by skin prick test or in vitro IgE tests, while the portion of allergy sustained by the cell-mediated mechanism is neglected, ...

Betalactam (BL) antibiotics are the most common cause of drug-induced hypersensitivity reactions (DHR). We present 2 clinical cases patients with suspected immediate BL DHR who underwent drug allergy workup according to standardized diagnostic procedures, including skin tests (STs: prick, prick test, and intradermal [IDTs]) provocation (DPTs).1 ST results became positive after first DPT dose. T...

BACKGROUND The nutritional quality of soybeans (Glycine max) is compromised by a relative deficiency of methionine in the protein fraction of the seeds. To improve the nutritional quality, methionine-rich 2S albumin from the Brazil nut (Betholletia excelsa) has been introduced into transgenic soybeans. Since the Brazil nut is a known allergenic food, we assessed the allergenicity of the 2S albu...

BACKGROUND Occupational allergy to latex is generally reported from occupational groups such as health care workers; however, few reports derive from other occupational settings. METHODS Two male subjects working as loom tuners in a textile manufacturing plant developed severe allergic reactions during the cutting and weaving of elastic bands, initially not suspected to contain latex constitu...

fractional exhaled nitric oxide (feno) has been suggested as a non-invasive biomarker of airway inflammation, which is increased in atopic subjects. whether sensitization to particular allergens is a predictive factor for increased feno levels is not yet fully understood. we conducted a retrospective cross-sectional study. from october to december in 2015, the medical documents of 127 mild, ste...

Methods Retrospective analysis of clinical files and results of skin testing and DPT (drug provocation tests) from January 2011 to December 2013. All patients were studied according to standardized diagnostic procedures of ENDA/EAACI: serum sIgE (specific IgE) (ImmunoCAP, ThermoFisher) to penicillin G/V, amoxicillin and ampicillin; skin prick and IDT (intradermal tests) to PPL/MD (DAP, Diater),...

BACKGROUND Diagnosis of food allergy is difficult in children. Food allergies are diagnosed using several methods that include medical histories, clinical examinations, skin prick and serum-specific immunoglobulin E (IgE) tests, radio-allergosorbent test (RAST), food challenge, and supervised elimination diets. In this study we evaluated allergies to cow's milk, egg, peanut, and fish in childre...
