[Thrombotic microangiopathy: when time is the key factor!]. / Microangiopathie thrombotique: quand le temps presse.

Thrombotic microangiopathy or "TMA" including thrombotic thrombocytopenic purpura (TTP) and hemolytic uremic syndrome (HUS) became a public health problem following the European outbreak of E. coli (O104:H4) gastroenteritis in 2011. A rapid diagnosis and therapy in an intensive care unit provide better patient survival and lower cost for society. Supportive treatment has significantly improved the prognosis over the past decade and includes fresh frozen plasma for TTP, plasmapheresis for HUS, and recently a new therapeutic agent: anti-C5 antibodies. We will provide in this article, through the current literature and four cases encountered in our department, to establish an algorithm to manage patients with TMA.

[Geriatric patients with chronic kidney insufficiency: which antalgia?]. / Patients gériatriques insuffisants rénaux chroniques: quelle antalgie ?

Pain is a leading cause of office visits. In the geriatric population, it is known that the prevalence of renal failure increases exponentially with age, modifing the elimination of drugs and of their metabolites. What analgesia should be offered to these patients? The holy grail would be a medication without renal elimination, without toxic metabolites and without nephrotoxicity. Based on the literature we try to propose a specific approach to analgesia in older patients with kidney insufficiency, in order to help practitioners to better prescribe for this group of patients.
