Nausea is a common symptom among patients affected by chronic diseases or undergoing various treatments. Because nausea can result from many origins, there is a large differential diagnosis to explore. Its pathophysiology relies on numerous neurotransmitters, on which 5 types of antiemetic antagonists are effective (NK-1 receptor antagonists, antiserotoninergic, antidopaminergic, antihistaminic and anticholinergic agents). Glucocorticoids and benzodiazepines are also used to treat some types of nausea. Choosing the appropriate antiemetic can improve quality of life and treatment compliance.Les nausées sont un symptôme retrouvé fréquemment en consultation chez les patients atteints de maladies chroniques et/ou traités par certains médicaments. L’absence de spécificité des nausées doit faire ouvrir un large diagnostic différentiel à explorer. Le mécanisme physiopathologique fait intervenir de nombreux neurotransmetteurs, que 5 familles d’antiémétiques antagonisent (antisérotoninergiques, antidopaminergiques, antagonistes du récepteur NK-1, antihistaminiques, anticholinergiques). Les glucocorticoïdes et les benzodiazépines sont également utilisés pour traiter certains types de nausées. Le choix du traitement le plus adéquat amène une amélioration de la qualité de vie et une meilleure compliance thérapeutique.

The standard management of a single brain metastasis is usually maximal resection when feasible followed by radiotherapy. In case of multiple lesions, several options have to be considered depending on the natural behavior of the primary tumor, the localization of brain lesions, their functional impact and related symptoms. In case of life-threatening brain metastasis, debulking surgery is often proposed first, with the risk of major bleeding and postponing the initiation of other treatments. This approach is now challenged by the rapid tumor shrinkage that could be observed with novel targeted therapies. Here we report the case of a patient suffering from a melanoma with multiple brain metastasis, treated with BRAF and MEK double blockade, with impressive and rapid response.
