[Adverse effects of licorice consumed as food: An update]. / Toxicités de l'exposition alimentaire à la réglisse : mise au point.

The word "licorice" refers to the plant, its root, and its aromatic extract. From a commercial point of view, Glycyrrhiza glabra is the most important species with a wide range of uses (herbal medicine, tobacco industry, cosmetics, food and pharmaceutical). Glycyrrhizin is one of the main constituents of licorice. Glycyrrhizin is hydrolyzed in the intestinal lumen by bacterial ß-glucuronidases to 3ß-monoglucuronyl-18ß-glycyrrhetinic acid (3MGA) and 18ß-glycyrrhetinic acid (GA), which are metabolized in the liver. Plasma clearance is slow due to enterohepatic cycling. 3MGA and GA can bind to mineralocorticoid receptors with very low affinity, and 3MGA induces apparent mineralocorticoid excess syndrome through dose-dependent inhibition of 11ß-hydroxysteroid dehydrogenase type 2 in renal tissue. The cases of apparent mineralocorticoid excess syndrome reported in the literature are numerous and sometimes severe, even fatal, most often in cases of chronic high dose consumption. Glycyrrhizin poisonings are characterized by hypertension, fluid retention, and hypokalemia with metabolic alkalosis and increased kaliuresis. Toxicity depends on the dose, the type of product consumed, the mode of consumption (acute or chronic) and a very large inter-individual variability. The diagnosis of glycyrrhizin-induced apparent mineralocorticoid excess syndrome is based on the history, clinical examination, and biochemical analysis. Management is primarily based on symptomatic care and stopping licorice consumption.

[The American opioid overdose crisis: A threat for France?] / La crise des overdoses américaines : une menace pour la France ?

Since the 2000s, a concerning increase in opioid-analgesic-related overdoses and deaths has been reported in the United States. In contrast with opioid overdoses reported in the 80-90s mostly involving heroin, currently it is the misuse of opioid analgesics that is mainly responsible for opioid overdoses. This crisis is related to factors (not limited to the US) which occurred during the 90s and which have led to a broad prescription of opioids in non-cancer pain. In Europe and France, there is (but to a much lesser extent) an increase in strong opioid consumption and in opioid prescription related morbi-mortality. This situation, which can be described as "worrying" today, requires awareness among the French medical community, both upstream (rational prescription of opioids) and downstream (optimal management of opioid poisoning) from the opioid prescription.
