Medical certification reduces the number of children requiring allergen elimination diets for school lunches.

BACKGROUND: Following the increase in the number of children with food allergies, support systems are now required for school lunches, but a large-scale factual investigation has not been carried out. OBJECTIVE: We evaluated the features of elimination diet due to food allergy and the support system in kindergartens and schools. METHODS: A prefecture-based questionnaire survey regarding measures for food allergies in school lunches of all kindergartens, public elementary schools, and public junior high schools (631 facilities) was conducted in Oita Prefecture, Japan. RESULTS: The recovery rate of the questionnaire was 99.5%, which included 106,008 students in total. A total of 1,562 children (1.5%) required elimination diets. The rate of children on elimination diets in kindergartens and elementary/junior high schools that required medical certification by a physician was 1.2% (324 among 27,761 children), which was significantly lower than the 1.8% of children (1,227 among 68,576 students) on elimination diets at the request of guardians without the need for medical certification (p < 0.0001). A total of 43.9% of the kindergartens and schools said that they would contact guardians if symptoms were observed after accidental ingestion, while a low 8.1% stated that they provided support to children themselves, including the administration of adrenaline auto-injectors. CONCLUSION: Medical certification reduces the number of children requiring elimination diets, but it has not been adequately implemented. Furthermore, waiting to contact guardians after symptoms are observed may lead to the delayed treatment of anaphylaxis. Cooperation between physicians and teachers is desired to avoid the overdiagnosis and undertreatment of children with food allergies.

Central retinal vein occlusion in a pediatric patient with SLE and antiphospholipid antibodies without anti-cardiolipin or anti-ß2 glycoprotein I antibodies.

BACKGROUND: Antiphospholipid antibody syndrome is characterized by venous and/or arterial thrombosis, and is found in patients with systemic lupus erythematosus. Its diagnosis requires the presence of both clinical and laboratory findings, such as positive anti-cardiolipin and anti-ß2 glycoprotein I antibodies and lupus anticoagulant. However, cardiolipin is a minor component of the vascular endothelial cells in human, and phosphatidylcholine and phosphatidylethanolamine are major components. CASE PRESENTATION: A 15-year-old female suddenly developed massive left intraretinal hemorrhaging due to central retinal vein occlusion. She also had a butterfly rash, and her laboratory findings revealed positive serum anti-nuclear antibodies and decreased serum complement. During this episode, she was diagnosed with systemic lupus erythematosus. Although she was negative for serum anti-cardiolipin IgG and anti-ß2 glycoprotein I antibodies as well as lupus anticoagulant, her serum anti-phosphatidylcholine, anti-phosphatidylethanolamine, anti-phosphatidylinositol and phosphatidylserine IgG antibodies levels were increased. CONCLUSION: Pediatric cases of central retinal vein occlusion are rare. Even in patients without anti-cardiolipin or anti-ß2 glycoprotein I antibodies and lupus anticoagulant, there is the potential for the development of antiphospholipid antibody-related thrombosis.
