BACKGROUND Potent allergens such as hymenoptera venoms are capable of inducing severe and life threatening clinical reactions. Percentage of false negative results obtained by the usual diagnostical methods is comprised between 10 and 25%. OBJECTIVE Evaluation of the sensitivity and the specificity of cellular tests and particularly evaluation of a new(More)
This paper clarifies the relation between synchronization and graph topology. Applying the Connection Graph Stability method developed by Belykh et al. [2004a] to the study of synchronization in networks of coupled oscillators, we show which graph properties matter for synchronization. In particular, while we explicitly link the stability of synchronization(More)
Is there a port-cat syndrome in food allergy? Many clinical observations have revealed a frequent association between allergy to cat epithelia in subjects who have allergy to pork meat. This second part, from clinical tests such as skin tests and laboratory tests such as CAP RAST, electrophoresis, Western blot and chromatography, confirms the existence of a(More)
This work is a study of the frequency of the association between sensitivity to pork meat and cat epithelia. Comparison with a reference population that was not sensitized to pork meat, shows that this association is highly significant. This suggests therefore the possibility of a crossed allergenicity. If there is a real crossed allergenicity between pork(More)
The basophil activation test (TAB) clearly shows evidence to Hymenoptera venoms. Comparison of the TAB value with the clinical history allows fixation of a threshold that will anticipate the type of clinical reaction by the TAB value. For the technique of TAB 3 dilutions are used. The basophil activation values produce a threshold for each dilution. For the(More)
This work confirms that the common allergen in subjects who are doubly sensitized to cat and pork is quite different from that of subjects who are mono-sensitized to cat. The common protein is Albumin MW 67 Kda in the pork/cat syndrome, while the major allergen Feld One is characteristic in patients who are monosensitized to cat.
Food allergy is becoming more frequent, with 6% of asthmatics reporting an isolated food allergy, and 5 to 6% of atopic dermatitis patients also have either a single or multiple true food allergy. There is value in immuno-biological diagnosis by: Measurement of total serum IgE. Measurement of mono-allergen-specific IgE, following a measurement by a(More)
Anaphylaxis to paracetamol exists and perhaps nowadays diagnosis is not confined to clinical evidence of: The repeatability of clinical symptoms. Skin tests. Provocation tests. But also by immuno-biological evidence. Application of the test of Activation of basophils by Flow Cytometry and measurement of leukotriene C4 have been nowadays largely validated(More)
A protocol has been produced for the study of anaphylactic accidents that occur post-operatively that allows definition of the anaphylactic origin, and so reactions that are mediated by IgE in post-operative accidents. This protocol occurs in two stages, the first is done in the minutes and hours that follow the anaphylactic accident, and the second a month(More)
Objective improvement in the diagnosis of immuno-allergology can only be obtained by application of reliable and reproducible immuno-biological methods, but until now, only measurements of total and specific IgE can be used and this has certain limitations. Presence of specific serum IgE, correlated with skin tests, favours a sensitization and implies(More)
