Retrospective and cross-sectional study on 60 patients with cosmetic allergy treated at Department of Allergology – Clinical Immunology and National Institute of Dermatology and Venerology in Bach Mai Hospital between January 1992 and February 2004. Results: there are plentiful and diversified cosmetics caused allergic reactions with 30 types divided into 6 groups: skin care cream (33.3%), dye hair (20.0%), powder foundation, toilet soap, other creams (21.7%), and other cosmetics. Allergic reactions commonly occurred in females, with common clinical symptoms such as itching, erythema, prurigo, vesicle, infected vesicle, edema, etc. They were treated by corticosteroid, anti-histamine H1, antibiotics, solution infusion, vitamin and other drugs. There was no death or more serious allergic reactions.

During 1981-2000, in Bach Mai Hospital, 1,465 patients with drug allergy were consulted and treated. Among them, 9 cases died of Stevens-Johnson and Lyell syndrome. There were 121 kinds of drug allergy. 215 of health staffs suffered the drug allergy showed the risk of allergy among health staffs was higher 2.5 times.

The study was carried out on 490 workers from 3 pharmaceutical enterprises, and 589 hospital staffs (nurses, pharmacist) from hospitals in Hanoi. Results shown that the prevalence of allergy to beta-lactam antibiotics in pharmaceutical workers and hospital staffs is very high and clearly affected by occupational factors. This issue requires the functioning agencies having solutions of early detection, management and prevention for labor force working in pharmaceutical and health branch.

OBJECTIVETo investigate the epidemiological characteristics of intolerance to 14 foods in children and the relationship between food intolerance and disease of various systems.

METHODSSerum samples of 2434 children with diseases were collected for food intolerance testing between January 2009 and October 2012. Allergen-specific IgG antibodies to 14 foods were detected using enzyme-linked immunosorbent assay. The children's intolerance to different foods and its relationship with age, sex and disease of various systems were analyzed.

RESULTSAmong these children, positive rates of intolerance to milk and eggs were as high as 74.16% and 66.47% respectively, while positive rates of intolerance to chicken and pork were relatively low (0.29% and 0.21% respectively). The overall positive rates of food intolerance were 12.579% and 12.470% in males and females respectively. For infants, the highest intolerance rate was to milk; for preschool and school-age children, the highest intolerance rates were to milk and eggs respectively; for children in adolescence, the highest intolerance rate was to eggs. Among children with food intolerance involving single system, those with developmental abnormality or immune system disease had the highest overall positive rate of food intolerance. Children with double-system diseases had an overall positive rate of food intolerance as high as 13.393%. Among the children involving various systems, the positive rate of intolerance to milk and eggs were higher than other food.

CONCLUSIONSFactors influencing food intolerance in children include food categories and age. There may be a relationship between food intolerance and disease of various systems, and this is significant to the growth and development of children.

Atopic dermatitis (AD) is a chronic, relapsing, inflammatory skin disease. Children with AD tend to have a higher prevalence of food allergies. This study investigated the clinical significance of food sensitization in AD patients. A total of 266 AD patients participated in this study. The prevalence of food sensitization and clinically relevant sensitization were compared in the subjects according to their age and AD severity. Sera from all patients were analyzed for food-specific IgE levels using the Pharmacia CAP System FEIA. The serum specific IgE levels for egg, milk, peanut and soybean were measured. Patients were regarded as sensitized to the food if their food-specific IgE levels were above 0.35 kUA/L. Also the food-specific IgE levels, the so-called diagnostic decision point, which is recommended as the clinically relevant level, for clinical food allergy, as suggested by Sampson et al, was used as an alternative method. From the measurement of food-specific IgE antibodies of the four foods, egg was the most highly sensitized and the main causative allergenic food in children with AD. The positive rates of specific IgE to the four major food allergens, and the prevalences of clinically relevant food sensitization, were higher for all foods tested in the group less than 1 year of age, and were significantly higher in moderate to severe AD compared to mild AD in infants and young children. In summary, presence of food specific IgE is prevalent in infants and young children with AD, and clinically relevant food sensitization is important in Korean infants and children with moderate to severe AD.

554 pupils of Le Hong Phong primary school in Ngo Quyen district . Hai Phong city were enrolled in an investigation performed following the 25B from WHO concerning allergic diseases. Results were processing biostatistically. The prevalence is 37,32% in pupils, it is higher in girl than in boys. This prevalence increased progressively after 15 years old. The commonest conditions are respiratory allery, broncho-asthma 6.25%, allegic shinite-simusite 19,67%, urticaria 6,69, allergic reaction to medicaments 0,92%, to food 2,75%, to chemicals 0,97%, eczema 0,92%. Cold weather 33,64% and the change of weather 21,50% play important role in causing clinical symptom of allergic rhinite-simusite. In addition there are 14,02% of allergic response due to dust

The purpose of this study was to estimate the national prevalence of childhood asthma and other allergic diseases in Korea, and to determine potential risk factors for the diseases. Stratified random samples of 42,886 were selected from 34 elementary (6-12 yr olds) and 34 middle schools (12-15 yr olds) nationwide, and 38,955 were in the final analysis. The Korean-translated modified version of the International Study of Asthma and Allergies in Childhood questionnaire was used in this cross-sectional survey. Twelve-month prevalences of the symptoms of asthma, rhinoconjunctivitis, and flexural eczema were 8.7%, 10.5%, 7.3% in 6-12 yr olds, and 8.2%, 10.0%, 3.9% in 12-15 yr olds, respectively. For allergic conjunctivitis, food allergy, and drug allergy, the prevalences in 6-12 yr olds were 11.2%, 6.5%, and 1.5%, respectively. Asthma and flexural eczema decreased significantly with age. Other significant risk factors were also noted. For 6-12 yr-old asthma, adjusted odds ratio (aOR) of body mass index was 1.21 with 95% confidence interval (CI) 1.0-1.48, aOR of passive smoking was 1.37 with 95%CI 1.24-1.51, aOR of carpet use was 1.28 with 95%CI 1.10-1.49. For 6-12 yr-old eczema, aOR of affluence was 1.22 with 95%CI 1.07-1.39. The control of obesity and passive smoking would be the most important preventive measures of allergic diseases.

With the exception of shellfish, the overall food allergy rates in Singapore have not reached the epidemic proportions of the West. The rates of egg, milk and fish allergies remain low. However, the patterns of some food allergies in Singapore have changed over the last decade. For example, peanut allergy, once rare in Singapore, is now the most common cause of anaphylaxis in children. Studies analysing lifestyle practices, particularly with respect to prevention of food allergy, are necessary in order for practitioners to understand global differences and maintain this low prevalence.

Oral food challenge is a definitive diagnostic test for immediate and occasionally delayed adverse reaction to foods. The gold standard for diagnosing food allergy is still the double-blind, placebo-controlled food challenge, but it is time-consuming, expensive and troublesome for physician and patients. Open oral food challenge controlled by trained personnel is useful and sufficient methods when concern of bias is low. We aimed to provide a practical guideline for oral food challenge in children for the diagnosis of suspected food allergy or the evaluation of food tolerance. We considered reasons, types, indications, contraindications, risks, benefits, detailed methods, practical performance, interpretations of test results, and treatments for the adverse reactions of oral food challenge.
