Aim: To explore whether gender, low birth weight, prematurity and birth type (vaginal vs. abdominal) affects skin prick test results. Methods: This cross-sectional study comprised 350 patients who applied with allergic respiratory symptoms and underwent skin prick test in-between February 2016-June 2016. The patients were asked for premature birth, low birth weight and birth type (vaginal vs. a...

Methods In 1994, the Canadian Asthma Primary Prevention Study (CAPPS) was established. This high-risk birth cohort has 2 sites, Winnipeg and Vancouver, Canada. Expectant mothers were recruited during the third trimester. Enrollment criteria were a first degree relative with asthma or two first degree relatives with other allergic diseases. Participants were prenatally randomized into control an...

Introduction: Skin prick testing (SPT) is a common test to diagnose IgE sensitization and the rate of adverse reactions is very low. Case Presentation: 29-year-old woman with anaphylactic reaction to routine SPT with 11 allergens (aero and food). Discussion: Allergy profile included multiple food and inhalant allergies, polysensitization, prior episode of anaphylaxis to mushrooms, active eczema...

BACKGROUND Chronic spontaneous urticaria (CSU) is a common skin disorder with etiology that is not well understood. METHODS In this study, we evaluated the prevalence of autologous serum skin test (ASST) and skin prick testing (SPT) to house dust mite (HDM) in 862 CSU cases in China. Clinical features, courses and treatment responses were also recorded. RESULTS The prevalence of positive AS...

Metamizol, a pyrazolone derivative, is commonly implicated in IgE-mediated allergic reactions. Skin tests have different sensitivity in drug allergy diagnosis and false positive or false negative results render their interpretation difficult, especially because the ranges of the tested concentrations have not been adequately investigated in all drugs. The objective of our study was to determine...

BACKGROUND Skin testing, correlated with patient history, is the accepted method of identifying clinically relevant aeroallergen sensitivity. Traditionally, intradermal tests are believed to be more sensitive in identifying aeroallergen sensitivity than the epicutaneous and percutaneous methods. Therefore, many allergy practitioners use the epicutaneous or percutaneous method first and, if the ...

the aim of this study was to assess the frequency of rhinitis in asthmatic infants. a cross-sectional study was conducted using clinical data obtained from a standardized allergy work-up form that includes specific questions on common allergic diseases. asthmatic patients were seen at the first visit to the pediatric allergy unit, from january 2001 to january 2006, were selected for analysis. d...

BACKGROUND Immediate-type hypersensitivity to animal proteins is a common problem in people occupationally exposed to animals. METHODS A 19-year-old female working as a voluntary zookeeper in her off-time suffered from hives on her forearms following contact to the fur of a giraffe. For diagnostic evaluation, skin prick tests, assessment of specific serum IgE antibodies, and basophil activati...

BACKGROUND Elevated fractional exhaled nitric oxide (FENO) associates positively with symptomatic atopy among asthmatics and in the general population. It is, however, unclear whether sensitization to common allergens per se- as verified with positive skin prick tests--affects FENO in healthy individuals. OBJECTIVE The aim of this study was to examine the association between FENO and sensitiz...
