[Differential diagnosis of status epilepticus in intensive care: about one case of sporadic Creutzfeldt-Jakob]. / Diagnostic différentiel d'un état de mal épileptique en réanimation: à propos d'un cas de Creutzfeldt-Jakob sporadique.

A 78-year-old man was admitted in the intensive care unit for epilepsy seizure (tonic-clonic seizure). Since three months, his wife reports motor dysfunction (weakness) and since two weeks, rapidly progressive changes in cognition (apraxia, akinetic mutism). The diagnosis of probable sporadic Creutzfeldt-Jakob on the basis of clinical, EEG and MRI lesions was made. Refining diagnostic criteria is probably needed, including the usefulness of repeated MRI with FLAIR and diffusion-weighted imaging.

[Allergic reactions to patent blue violet: mechanisms, frequency and treatment]. / Les accidents allergiques au blue patent violet. Mécanismes, fréquence et traitement.

The authors report their observation of a serious allergic incident involving the blue patent, hospitalisation in their intensive care unit, and extremely major therapy. They describe the three mechanisms of allergic reaction: real anaphylaxia, and anaphylactoid reaction, either by direct histamino-release, or by alternate activation of the complementary system. It would seem that, after doses of the differing fractions of complement in this patient, there was an activation of the complementary system. The authors emphasize the importance of preventive treatment: hypo-histamine, antihistamine, corticoid, and curative relative to the gravity of the disorders observed: cutaneous, cardiac, and respiratory. Finally, they recall that this test must be carried out in a hospital establishment with a reanimation unit.
