Le syndrome hépatorénal chez le patient cirrhotique [Hepatorenal syndrome in patients with liver cirrhosis].

Hepatorenal syndrome is a particular form of functional renal failure which may develop in patients with liver cirrhosis. On a clinical standpoint, precise diagnostic criteria have been established to clearly define this entity, whereas recent advances in the understanding of the biology of vasoactive mediators and the physiology of microcirculation have allowed to better anticipate its pathophysiological mechanisms. During the course of cirrhosis, sinusoidal portal hypertension leads to splanchnic and systemic vasodilation, responsible for a reduction of effective arterial blood volume. As a result, a state of intense renal vasoconstriction develops, leading to renal failure in the absence of any organic renal disease. At this stage, liver transplantation is the only definitive therapy able to reverse renal dysfunction. In recent years, innovative therapies have shown promise to prolong survival in patients with hepatorenal syndrome, including the administration of analogs of vasopressin (mainly terlipressin), the insertion of transjugular intrahepatic portosystemic shunts and the use of novel techniques of dialysis. On a preventive viewpoint, several simple measures have been shown to reduce the risk of hepatorenal syndrome in cirrhotic patients, including the appropriate use of diuretics, the avoidance of nephrotoxic drugs, the prophylaxis of spontaneous bacterial peritonitis and optimal fluid management in patients undergoing large volume paracentesis.

La violence ou le traumatisme médical dans une consultation pluridisciplinaire spécialisée [Violence our medical trauma in specialized multidisciplinary consultation].

In this article a particular patient/physician relationship is described and analyzed: The described interaction between patient and physician during a consultative investigation by several specialists differs markedly from the common trustful relation between a patient and his family doctor. In this context the term and phenomenon pain is discussed and the necessity for an understandable, patient-oriented presentation of diagnosis and hypotheses considering the patient's individual bio-psycho-social dimension is stressed. Consequences for student education are mentioned.

Avancées recentes dans le traitement des carcinomes corticosurrénaliens [Recent advances in the treatment of adrenocortical carcinomas].

Adrenocortical carcinomas are rare and aggressive malignant tumors, with an incidence of 1 to 2 cases per million inhabitants. Their diagnosis is made in three clinical situations: during the work up of a syndrome of hormonal hypersecretion, during the work up of locoregional symptoms, or incidentally during an unrelated radiological procedure. Surgery is usually indicated except in situations of advanced metastatic disease. Adjuvant chemotherapy with mitotane is associated with a significant increase in disease-free survival when the drug is administered at adequate therapeutic dosage. Novel anti-mitotic therapies have recently been described for treating recurrent adrenocortical carcinoma under mitotane treatment, but their overall efficacy remains unsatisfactory.
