Key issue is that if may contain foods have caused anaphylaxis
MMR grown in chick embryoFlu vaccine residual amounts of egg proteins (≤ 1 mcg ovalbumin) Abidec contains peanut oil, deproteinated-no riskClarityn contains lactoseSingulair 10mg film coated contains lactose not paediatric 4mg chewable/oral granules 5mg chewable do not.
Raw versus boiled peanutsFrying or boiling peanuts, as practiced in China, appear to reduce the allergenicity of peanuts compared with the method of dry roasting IgE binding to Ara h 2 and Ara h 3
Maria Said Anaphylaxis AustraliaWorldwide huge complex issue
Cannot eliminate all risk, have to manage itNo truly allergy free environment despite detergents, hot waterIn cases of anaphylaxis resulting from a food avoided need to think outside the box

Competencies adapted from care pathway Food Allergy in Children 2011 Local implementation Multidisciplinary team Creating networks Know: what foods are likely to contain trigger foods. clinically relevant cross-reactivities and co-reactivities appropriate nutritional requirements for children at different ages signs and symptoms of faltering growth Be able to: advise on appropriate dietary exclusion and alternatives including practical, individualised cultural and age appropriate advice advise on appropriate avoidance of non food triggers (e.g. cosmetics and toiletries) ensure nutritional sufficiency in the context of dietary restrictions during different stages of childhood monitor growth accurately and assess nutritional intake revise dietary care plan to ensure that optimal growth and nutrition are maintained
The parent/carer/child needs to know: what foods and drinks to include & avoid how to interpret food labels alternative sources of nutrition to ensure adequate nutritional intake food avoidance if breastfeeding information on the most appropriate hypoallergenic formula or milk substitute if formula-fed information about the support available and details of how to contact support groups.

Nutrition for infants and children www.publichealth.hscni.net/ www.hse.ie www.fsai.ie
Nutrition requirements for children Adapted from Recommended Dietary Allowances for Ireland 1999, Food Safety Authority of Ireland
Faltering growth & food allergy Failure to grow at the expected rate: Height and weight velocity are the most sensitive indicators that energy requirements are being met Inappropriately restricted diets Associated asthma, chronic skin infections Appropriate centile reference charts
Poor parallel centiles - centile position falls, continued growth parallel to the 0.4 centile for weight and height. This occurs when children adapt to the abnormal situation of poor nutrition and the situation becomes chronic. Height and weight centiles markedly discrepant -where discrepancies in the centile ranking occur . Most children will have weight centile no more than 1 -2 centile spaces below their height. Family pattern discrepant - marked discrepancies from the parents and other family members attained height centiles. Retrospective rise - improvement in the child's centile position when nutrition is improved. Saw tooth - dipping. Weight goes up and down, crossing and recrossing centile positions.
