Transplacental passage of fluorides was studied in 25 randomly selected neonates. Blood samples collected simultaneously from the mother and the umbilical cord showed that average fluoride concentration in the cord blood was 60% of that in mother’s blood. When concentration in the mother’s blood exceeded 0.4 ppm, the placenta acted as a selective barrier.
Serum Concentration of Fluoride in Patients with Alcoholic Liver Cirrhosis from the Lublin Region in Eastern Poland.
In view of previous reports, it is important to determine the relationship between liver function and the level of fluoride in the serum. The aim of this study was to investigate serum concentrations of fluoride in 72 patients with alcoholic liver cirrhosis, living in the region of Lublin (Eastern Poland)
Serum fluoride levels following commencement of methoxyflurane for patient analgesia in an ambulance service.
Editor—Methoxyflurane, once a frequently used anaesthetic agent,1 is re-emerging as an inhalation analgesic. In modern practice, it is given in doses of up to 6 mL via a proprietary patient-controlled self-delivery device2 with an activated carbon filter designed to adsorb some methoxyflurane vapour from the patient's exhaled breath.3 Methoxyflurane is an
Periarticular calcifications containing giant pseudo-crystals of francolite in skeletal fluorosis from 1,1-difluoroethane 'huffing".
Highlights Diagnosing inhalant use disorder can be lifesaving. Chronic inhalation of F--containing vapors can cause skeletal fluorosis (SF). SF can elevate bone density and cause periostitis and ectopic calcification. Francolite is a carbonate-rich fluorapatite. Periarticular calcification in SF can comprise giant pseudo-crystals of francolite. Inhalant use disorder is a psychiatric
The relationship between human ionic plasma fluoride and serum creatinine concentrations in cases of renal and cardiac insufficiency in a fluoridated community
Previous studies have shown that renal and cardiac insufficiency cause an elevation of ionic plasma fluoride (IPF) concentration in patients suffering from these diseases. The relationship between serum or plasma fluoride concentration and the degree of renal impairment has been tested only twice; with somewhat contrasting results, although some previous
Voriconazole-associated periostitis: Pathophysiology, risk factors, clinical manifestations, diagnosis, and management.
Voriconazole use has been associated with osteoarticular pain and periostitis, likely due to high fluoride content in the drug formulation. This phenomenon has been described primarily with high dosage or prolonged course of voriconazole therapy in immunocompromised and transplant patient populations. Patients typically present with diffuse bony pains associated with
