BACKGROUND Skin prick tests (SPT) are widely used both in clinical diagnostics and in research. The standardization of allergen extracts is well documented to be crucial for the validity of SPT, whereas less emphasis has been placed on reproducibility and the SPT procedure itself. The objectives of this study are to clarify how the double skin prick test procedure influence the sensitivity and ...

OBJECTIVE It is well-known that number of drugs may interfere with wheal reactions in skin prick test. However, the effect of long-term use of montelukast, a cystenil leukotriene receptor antagonist, on skin prick test hasn't been full elucidated. The aim of present study was to demonstrate the effect of montelukast on skin prick tests (SPT). METHODS This is a single-center, randomized, doubl...

OBJECTIVES To investigate the incidence of skin prick test (SPT) positivity in patients with eczematous external otitis. METHODS Forty-six patients with eczematous external otitis and forty-four healthy volunteers were included in the study. All the patients were skin-tested by prick test. Reactions were assessed by the degree of redness and swelling and the size of the wheal produced. RESU...

We conducted a prospective study at King Chulalongkorn Memorial Hospital, from June 2001 to November 2003, to identify the contribution of food allergy to urticaria in children. During the study period, 100 children with urticaria were enrolled, 36 of whom had a history suspicious of food allergy. Fifteen of 100 patients had fever (9 from upper respiratory tract infections, 4 from diarrhea and ...

the pathogenetic mechanism of nasal polyps remains unknown, although allergy has been cited as an important factor in the etiology of nasal polyposis. currently there is no definite histological criterion for differentiation of allergic from inflammatory nasal polyp. however, in a few studies, tissue eosinophil count has been used for this. this study aimed to find out the agreement rate of ski...

PURPOSE To evaluate the frequency of banana sensitization and allergy among a group of atopic Egyptian children in relation to parental/self reports. METHODS This is a case-control study included 2 groups of allergic children with and without history of banana allergy, each included 40 patients. They were subjected to skin prick test (SPT) using commercial banana allergen extract and prick-pr...

Forty-one patients stung by wasp and 29 by bee were evaluated by comparing the correlation between skin prick test (SPT), Phadebas radioallergosorbent test (P-RAST) and Magic Lite SQ Specific IgE assay (LIA). All patients had had a systemic reaction to insect sting. In the patients stung by bee we found agreement between SPT and P-RAST, and SPT and LIA. Similarly, there were no significant diff...

BACKGROUND There are few references of allergic reaction to beans in childhood. We report the case of a seven years old boy who suffered from angioedema associated to inhalation of vapours from cooked white bean. METHODS skin prick tests (SPT) were performed by prick-by-prick with cooked white bean and legumes. It was also determined total IgE and specific IgE antibodies to bean and legumes w...

Taking medical history, physical examination, and performing some in vivo and in vitro tests are necessary for the diagnosis of allergy. Skin prick test (SPT) is considered as the standard method and first-line approach for the detection of allergic sensitization. Although mainly SPT is used for the detection of allergic sensitization, intradermal skin test (IDST) may be necessary, especially i...
