[The national survey of immediate type of XXXX ].

@entity1 @entity566 @entity3505 @entity5419
BACKGROUND: The actual conditions regarding immediate type @entity5419 have not been fully understood. Appropriate countermeasures have not been taken so far. The objective of our research is to identify the actual conditions of immediate type @entity5419 in Japan for the purpose of contributing to future practices. SUBJECT: We conducted a survey on the @entity1 in collaboration with 2689 domestic hospitals which have pediatrics and more than 100 beds. We focused on these cases who presented with symptoms of @entity566 within 60 minutes of the intake of any offending food. RESULT: 60.4% of collaborators returned the questionnaire. We investigated 1420 cases in 498 hospitals. Average age of cases was 6.7+/-13.1 (Mean+/-SD). Ages not more than 8 years-old comprised 80.1% of the whole population. The most common offending foods were eggs, milk products, @entity3505 , buckwheat, fish and fruits. In addition, offending foods varied depending on age. The clinical symptoms appeared at 24.2 minutes+/-19.4 minutes (Mean+/-SD) after the intake of offending foods. The most common clinical symptom was observed on the skin and respiratory organs. CONCLUSION: Based on the results of this study, the Ministry of Health, Labor and Welfare amended the ministerial ordinance concerning the @entity566 food labeling system. Five major offending foods (eggs, milk, @entity3505 , buckwheat, and peanuts) were designated as ingredients to be specified on the label.
