Abstract
Volatile anesthetic agents, such as sevoflurane, are increasingly used for long-term sedation in intensive care units worldwide, with improved clinical outcomes reported in recent studies due to favorable pharmacological properties. Despite possible renal toxicity related to the production of plasma inorganic fluoride and concerns related to reversible impairment of renal concentrating abilities, renal injury associated with sevoflurane sedation has rarely been reported in the intensive care unit setting. We hereby report 3 cases of nephrogenic diabetes insipidus associated with prolonged sevoflurane sedation using the AnaConDa device and review the possible mechanisms of renal toxicity.

Effect of sodium fluoride on concentrating and diluting ability in the rat
Mechanisms for the concentrating defect produced by fluoride were examined in the rat. Free-water clearance at all levels of delivery was normal after 5 days of chronic fluoride administration in the hereditary hypothalamic diabetes insipidus rat. In the Sprague-Dawley rats, during moderate fluoride administration (120 micronmol/kg per day), urine osmolality

Assessment of renal and hepatic dysfunction by co-exposure to toxic metals (Cd, Pb) and fluoride in people living nearby an industrial zone.
Highlights Impact of F, Cd & Pb on human health is related to the various routes of exposure. Cd, Pb & F levels in human blood was higher around the phosphate plant in Togo. Cd, Pb &F content in human blood declined while moving away from phosphate plant. Biochemical

Taurine ameliorates renal oxidative damage and thyroid dysfunction in rats chronically exposed to fluoride
Excessive exposure to fluoride poses several detrimental effects to human health particularly the kidney which is a major organ involved in its elimination from the body. The influence of taurine on fluoride-induced renal toxicity was investigated in a co-exposure paradigm for 45 days using five groups of eight rats each. Group I rats received

Deregulation of autophagy is involved in nephrotoxicity of arsenite and fluoride exposure during gestation to puberty in rat offspring.
Exposure to fluoride (F) or arsenite (As) through contaminated drinking water has been associated with chronic nephrotoxicity in humans. Autophagy is a regulated mechanism ubiquitous for the body in a toxic environment with F and As, but the underlying mechanisms of autophagy in the single or combined nephrotoxicity of F

Time-dependent changes of blood parameters and fluoride kinetics in rats after acute exposure to subtoxic hydrofluoric acid
OBJECTIVES: In our previous study, we reported that even a sublethal dose of hydrofluoric acid (HFA) could cause acute toxic effects 60 min after intravenous injection. This study was designed to investigate the time- and dose-dependent changes associated with these disorders. The serum fluoride (F) kinetics are also considered in the

Kidney: A potential target for fluoride toxicity
The kidneys are the organ responsible for clearing fluoride from the body. In the process of doing so, the kidneys are exposed to concentrations of fluoride that exceed, by a factor of 50, the concentration of fluoride in human blood. As such, the kidney have long been considered a potential

Fluoridation of drinking water and chronic kidney disease: Absence of evidence is not evidence of absence
A fairly substantial body of research indicates that patients with chronic renal insufficiency are at an increased risk of chronic fluoride toxicity. Patients with reduced glomerular filtration rates have a decreased ability to excrete fluoride in the urine. These patients may develop skeletal fluorosis even at 1 ppm fluoride in the drinking water.

Fluoride as a Cause of Kidney Disease in Animals
Because the kidney is exposed to higher concentrations of fluoride than all other soft tissues (with the exception of the pineal gland), there is concern that excess fluoride exposure may contribute to kidney disease - thus initiating a "vicious cycle" where the damaged kidneys increase the accumulation of fluoride, causing in

Fluoride & Kidney Stones
It has long been suspected that fluoride may contribute to the formation of kidney stones. This suspicion has recently gained support from a study of an American man with skeletal fluorosis. According to the authors: "A new, important, medical problem (that seemed temporally related to cessation of fluoride exposure and subsequent negative calcium
