INTRODUCTION — The oral allergy syndrome (OAS) describes allergic reactions that occur upon ingestion of certain fresh fruits, nuts, vegetables, or spices in pollen-sensitized individuals. The symptoms result from contact urticaria of the mucosal surface that contacts the food. Symptoms are usually limited to the mouth and throat and observed with raw forms of the food, because the responsible ...

background: silicon hydrogel bandage contact lenses are used to enhance epithelial healing, control surface-generated pain, and prevent epithelial erosions after refractive surgery. considering the importance of faster reepithelialization in preventing complications of photorefractive keratectomy (prk) and the fact that the features and specifications of these commercially-available lenses are ...

Fermion compositeness and other new physics can be signalled by the presence of a strong four-fermion contact interaction. Here we present a study of leqq and !&?e’ contact interactions using the reactions: et!? --f e’+e’-, b&, CC at future e+elinear colliders with fi = 0.5 5 TeV and p+pcolliders with 4 = 0.5,4 TeV. We find that very large compositeness scales can be probed at these machines an...

We discuss cross-reactions that can occur when a patient allergic to a specific allergen also reacts to a similar allergen. Currently, The American Contact Dermatitis Society Contact Allergy Management Program, which allows physicians to identify safe products for their patients, uses a 10% threshold to distinguish significant cross-reactors. New clinical data from a patch testing center along ...

The in vivo functions of interleukin-3 (IL-3) were investigated by generating IL-3-deficient mice. Although hematopoiesis was unimpaired in homozygous mutant animals, contact hypersensitivity reactions were compromised. IL-3 was required for efficient priming of hapten-specific contact hypersensitivity responses, but was dispensable for T-cell-dependent sensitization to tumor cells. These findi...

Because of their anti-inflammatory activity, corticosteroids generally mask the clinical signs of a contact dermatitis to a corticosteroid preparation. The lesions usually present as chronic dermatitis, and the patients mostly report not exacerbations but failures to respond to corticosteroid therapy. Moreover, masking also occurs with patch-test reactions obtained with corticosteroid preparati...

the effect of geometry and material of the micro/nano particle on contact mechanic for manipulation was studied in this work based on atomic force microscopy. hertz contact model simulation for eph biological micro particle with spherical, cylindrical, and circular crowned roller shape was used to investigate the effect of geometry on contact simulation process in manipulation. then, to validat...

Eye drops contain several ophthalmic medications which can produce allergic reactions. We report the case of a patient with contact dermatitis from neomycin and a probable fixed exanthema after parenteral administration of tobramycin who tolerated topical tobramycin and other aminoglycosides.

Oral lichenoid reaction is a clinical entity characterized by microscopic features of hypersensitivity due to foreign body or contact reaction. It is usually presented in the cheek mucosa after chronic contact irritation from various materials used in dentistry. Amalgam restoration of tooth cavities has been used for many decades. This filling material is occasionally suspected for chronic epid...

Allergic contact dermatitis is the most common job-related disease of the western world. The only available treatments are avoidance of contact with the allergen and the use of potent corticosteroids. Recently, the role of cytokines in the pathogenesis of this disease has been studied and, besides defining the key molecules and basic cellular immune responses responsible for disease development...
