[Importance of blood tests for the diagnosis of drug allergies]. / Intérêt des tests sériques pour le diagnostic des allergies médicamenteuses.

This work is devoted to the study of 22 dossiers of persons who have presented with clinical signs following taking a drug. The study was confined to patients in whom the symptoms had as origin a hypersensitivity (true or non-specific by histamine release). This study has allowed analysis of the value of several serological tests (measurement of leukotrienes, activation of basophils and T specific lymphocytes) in diagnosis and so to define the path to take that is best adapted to each case. The conclusion presents an agreement between the suspected diagnosis, after allergy enquiry and prick-tests, and the results of serological tests.

[Value of esophageal scintigraphy in exploration of a gastro-esophageal reflux in a respiratory patient]. / Intérêt de la scintigraphie oesophagienne dans l'exploration d'un reflux gastro-oesophagien chez le patient respiratoire.

Patients with respiratory pathologies in the forms of tracheitis, rhino-sinusitis, and asthma sometimes have symptoms of gastro-oesophageal reflux, that should be taken into consideration in order to treat the co-factors associated with the etiopathology. However, these patients, because of their respiratory handicaps, are frequently unwilling to submit themselves to traumatic investigations. Oesophageal scintigraphy, because of its perfect tolerance and reliability, seems to be an examination that is adapted to the situation to resolve this dilemma.

[Value of specific IgE and IgG4 measurements in the follow-up of a hymenoptera venom immunotherapy treatment: apropos of 82 cases]. / Intérêt du dosage des IgE et IgG4 spécifiques dans le suivi d'un traitement d'immunothérapie aux venins d'hyménoptères: à propos de 82 cas.

The work is devoted to the study of 82 dossiers of patients who were treated by immunotherapy (IT) to hymenoptera venoms, following various manifestations. The study has permitted analysis of the value of measurement of specific immunoglobulins, both IgE and IgG4 (1), in following IT in patients who were treated for at least three years. It especially emphasized the usefulness of adopting management that is appropriate to the clinical and biological characteristics of each patient.
