We recently discussed the widespread occurrence of allergies and the various means of diagnosing and treating them. 1 Although allergy symptoms are generally associated with physical problems, research shows that behavioral problems such as hyperactivity in children, depression, and possibly even schizophrenia may also be associated with allergy. Part three will focus on behavioral aspects of a...

Histamine is synthesized via histidine decarboxylase (HDC) in wide types of immune cells and is involved in abundant physiologic and pathologic processes. Histamine is a mediator released during inflammatory reactions, such as food allergy. Food allergy is immunological reactions to 'fight off' specific allergens within food in susceptible individuals. The aim of this study is investigation of ...

Epidemiological evidence suggests that there is a link between asthma and food allergy. The aim of this study was to estimate the prevalence of food allergy in asthmatic children and to evaluate a possible impact of food allergy on asthma severity. The study enrolled 103 asthmatic children (mean age: 11 years). Skin prick-test, dosage of specific IgE to a standardized panel of inhalant and food...

introduction cow’s milk allergy is the most common food allergy in children. symptoms usually involve the skin and the gastrointestinal and respiratory tracts. gastrointestinal tract manifestations of cow’s milk allergy are nonspecific, and are the only type that can be diagnosed in all age groups. here, we report a rare case of cow's milk allergy in an infant with hypoalbuminemia and malnutrit...

Understanding of geographical differences in asthma prevalence may be helpful in explaining recent increases in the occurrence of asthma. We wondered whether differences in allergic sensitization or other factors could explain differences in reported occurrence of asthma between an urban centre and a neighbouring suburban area. From the European Community Respiratory Health Survey (ECRHS) quest...

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 eosinophi...

Background Prevalence of food allergy is considered to be increasing with some even suggesting a food allergy epidemic. We aimed to look at the changes in reported symptoms of food allergy and food allergen sensitisation over a 10 year period in the same geographical area. We compared the prevalence of reported food allergy and food allergen sensitisation in 9-10 year old children between the I...

This review explores the relationship between food allergy and asthma. They can share the same risk factors, such as parental allergy, atopic eczema, and allergen sensitization, and they often coincide in the same child. Coexistence may negatively influence the severity of both conditions. However, it remains to be determined whether food allergy may directly affect asthma control. An early foo...

It is a common misconception that food allergy can cause a wide variety of symptoms. A population study in the English town of High Wycombe showed a perceived prevalence of food intolerance of almost 20%, but double blind food challenge (the definitive test) provided objective evidence of symptoms related to food in fewer than 2% of subjects. This popular belief is fuelled by extensive and ofte...

This study examined data from three cross sectional surveys of 296 laboratory workers exposed to small mammals. Four indices of laboratory animal allergy were studied: symptoms suggestive of occupational asthma, symptoms suggestive of any occupational allergy, skin weals to animal urine extracts, and serum binding in radioallergosorbent tests with urine extracts. Pooled data from the three surv...
