BACKGROUND AND OBJECTIVES The most reliable method for confirming the causative allergens of allergic rhinitis is the skin prick test, followed by the multiple allergen simultaneous test (MAST), which reportedly has acceptable sensitivity and specificity. This study was designed to confirm whether a novel MAST-immunoblot assay can reliably diagnose allergic rhinitis. METHODS A retrospective c...

OBJECTIVES/HYPOTHESIS The objective was to determine the agreement of the positive results from a multiple skin prick test (SPT) device with the ability to determine a definable endpoint through intradermal dilutional testing (IDT) to compare semiquantitatively the degree of positivity of SPT results with quantitative results from IDT and to analyze the cost of immunotherapy based on SPT compar...

The skin prick test (SPT) is the most appropriate diagnostic approach to identify IgE sensitization to aeroallergens, foods, hymenoptera venom and some pharmacological compounds. SPT is considered a safe diagnostic approach, but several fatal or near-fatal reactions have been described. Based on the literature, the occurrence of systemic reactions with inhalant allergens has diminished over the...

Background: Asthma is the most common chronic disease of childhood. Exposure to allergens plays an important role in asthma. Recently, cockroach has attracted attentions as an important allergen. Objective: To evaluate cockroach allergy in Iranian children with asthma. Methods: 100 children with asthma were studied. After determination of asthma severity, serum total IgE and blood eosinophils w...

BACKGROUND In the subgroup of children with chronic cough, distinguishing children with allergic asthma from those with non-specific respiratory symptoms is difficult. We have focused on determination of diagnostic efficiency of serum total IgE, sIgE, and skin prick test in differentiation of asthmatic children from children with nonspecific respiratory symptoms. MATERIAL AND METHODS A total ...

Background Diagnosis of food allergy relies on clinical history, tests for allergen specific IgE and oral food challenges. A recent reaction consistent with IgE-mediated symptoms in conjunction with a positive allergen-specific IgE test (either skin prick test (SPT) or serum allergen specific IgE (sIgE)) is usually sufficient to diagnose food allergy. In the absence of a reaction history, a pos...

Decorative flowers are known to be a cause of occupational allergy in the floral industry. The allergic manifestations induced by flowers include asthma, rhinoconjunctivitis and urticaria. We present a case of a 55-year-old woman, who has been working for the last 30 years as a gardener with various kinds of flowers, e.g., Limonium sinuatum (LS), chrysanthemum, sweet William (Dianthus barbatus)...

BACKGROUND Studies have reported that children with atopic dermatitis (AD) have a high risk of adverse reactions at first egg ingestion. METHODS We enrolled 79 children with AD retrospectively and 45 children without AD (control group) prospectively, who had never eaten egg. All children underwent skin prick tests (SPT) with commercial extracts and prick by prick with natural food (raw and bo...

Methods A total of 59 cases were included in this study. Among those, 44 ( 74,5 %) had suggestive clinical history for latex allergy (SCHLA), and were submitted to latex skin prick test (SPT) and serum latex specific IgE test (sIgE– Immulite/Siemens) ; and 15 ( 25,5%) were healthy subjects, wich were considered negative controls for the diagnostic procedure. All the cases were submitted to LUT ...

Methods During general anaesthesia exposure to a number of different agents is common. In addition, anti-inflammatory drugs, antiemetics, antacids, antibiotics and analgesics may be used, and all may elicit reactions. Follow up is recommended to include serum tryptase, specific IgE, skin prick test (SPT), intradermal tests (IDT), basophil activation test (BAT) and provocations. We present a cas...
