The management of the allergic child at school: EAACI/GA2LEN Task Force on the allergic child at school. Allergy 2010; 65: 681–689. Allergy affects at least one-quarter of European schoolchildren, it reduces quality of life and may impair school performance; there is a risk of severe reactions and, in rare cases, death. Allergy is a multi-system disorder, and children often have several co-existing diseases, i.e. allergic rhinitis, asthma, eczema and food allergy. Severe food allergy reactions may occur for the first time at school, and overall 20% of food allergy reactions occur in schools. Up to two-thirds of schools have at least one child at risk of anaphylaxis but many are poorly prepared. A cooperative partnership between doctors, community and school nurses, school staff, parents and the child is necessary to ensure allergic children are protected. Schools and doctors should adopt a comprehensive approach to allergy training, ensuring that all staff can prevent, recognize and initiate treatment of allergic reactions.

    [Show abstract] [Hide abstract] ABSTRACT: Echographic images may be affected by geometrical, rotation or scale, distorsion, due to the scan system. A recognition method of echographic textures must therefore be rotation and scale invariant; moreover the features assumed to characterize the images would have to assure a good reliability and to allow a short computation time, also when the recognition method is implemented on small computers. The distorsion invariant method we have implemented uses as significant feature a vector whose components are the values of a modified Fourier transform (MFT) of the images. This MFT vector is calculated for groups of one or more reference images, whose size is chosen small enough that each image may be considered typical of a defined status of the tissue and large enough that texture is predominant. MFT vectors within each group are assumed to represent one possible status of the tissue. Images to be analyzed are then scanned by a window of the same size of the sample, for each scansion step MFT vectors are calculated and the Euclidean distance between these and that of the sample is patterned on a similarity map.

    [Show abstract] [Hide abstract] ABSTRACT: The recognition of echotexture in echographic images may fail due to the distortions introduced by the scan system. We have implemented a rotation and scale invariant recognition method of echographic textures. The significant features assumed to characterise the images are vectors whose components are the values of a modified Fourier transform (MFT) of the images. Our method assures a good reliability and allows a short computation time, also when implemented on small computers. The method has till now been proved over breast and thyroid images, exhibiting a very good discrimination capability.
