BACKGROUND Delayed-onset urticarial or maculopapular rashes are frequently observed in children treated with β-lactams. Many are labeled "allergic" without reliable testing. OBJECTIVE Determine the etiology of these rashes by exploring both infectious and allergic causes. METHODS Children presenting to the emergency department with delayed-onset urticarial or maculopapular rashes were enrol...

UNLABELLED Allergen immunotherapy dates back to 1911 and has been used successfully to treat large numbers of patients throughout the last century. CASE REPORT a 66-year-old woman presented with symptoms of allergic rhinitis and asthma due to sensitization to Cupressus arizonica. Specific immunotherapy was prescribed as a continuous 2-year treatment with a depot preparation of standarized and...

(Abstract) Recent studies have provided conflicting results in regards to equine intradermal skin testing and its use in defining causative antigens in IgE mediated diseases such as equine recurrent airway obstruction (RAO). This study was divided into two experiments. In the first experiment of this study, the hypothesis tested was normal horses would have minimal variability in the wheals for...

Five normal greyhounds were evaluated for hypersensitivity to various grasses, weeds, trees and fungi with both an intradermal allergy test and a commercial enzyme-linked immunosorbent assay (ELISA). All dogs were hyposensitized for 6 months with the same mixture of 14 allergens, according to the treatment schedule recommended by the commercial laboratory that provided the ELISA allergy test. F...

BACKGROUND Intradermal skin testing with inactivated vaccinia virus was evaluated for its prediction of residual immunity to smallpox. METHODS An intradermal skin test was performed with heat-inactivated Lancy-Vaxina. Two days later, the subjects were vaccinated with Lancy-Vaxina. The skin lesions resulting from this vaccination were used as a surrogate marker of residual immunity to smallpox...

The heat/capsaicin sensitization and intradermal capsaicin injection models are safe and noninvasive paradigms to generate stable, long-lasting, and reproducible injury capable of producing an area of both primary and secondary hyperalgesia. Risk of skin injury is substantially reduced since lower levels of thermal and chemical irritation produce long-lasting cutaneous hyperalgesia. Rekindling ...

Although there is a wide consensus on the efficacy of paratuberculosis vaccination to limit economic losses, its use has been restricted because of its interference in the diagnosis of tuberculosis. Data from a vaccine clinical trial in the Basque Country (Spain) has been evaluated in relationship with bovine tuberculosis intradermal test results. The trial included two herds applying a Test an...

antigens can also be applied on to the kin surface and skin prick testing (SPT) can be performed. Common allergens Intradermal tests are widely used to support the diagnosis of that are tested in skin prick tes are food, fungi, epthelia, dermatological and nondermatological diseases. They are pollens and mites. Intradermal tests can be done for similar mainly indicated for the detection of imme...

A case of chronic urticaria in a child 6 years old is described. The strong skin reactivity upon intradermal injection of autologous serum suggested an autoreactive pathogenesis; however, patient's serum was unable to induce histamine release from basophils in-vitro, indicating the presence of a histamine-releasing factor specific for mast cells, and possibly other than an anti-FcepsilonRI or a...
