[Determination of phenobarbital, mephenytoin and diphenylhydantoin in the surveillance of anticonvulsant treatment]. / Dosage du phénobarbital, de la méphénytoïne et de la diphénylhydantoïne dans la surveillance du traitement des anticonvulsivants

The authors describe a method of simultaneous estimation of phenobarbitone, mephenytoin and diphenylhydantoin in the blood. After extraction with ether, the methylation of these substances by trimethylanilinium hydroxide permits their rapid separation by gas chromatography. Heptabarbitone is used as internal standard and the chromatograph used is supplied with a thermoionic detector. The technique used is simple and rapid. Its reproducibility and sensitivity are satisfactory, permitting daily application to the supervision of anticonvulsant treatment, especially in Pediatrics.

Furosemide, mithramycin, and salmon calcitonin in hypercalcemia.

Twenty-nine patients with acute hypercalcemia secondary to carcinoma, myeloma and parathyroid adenoma have been treated with large doses of furosemide, mithramycin, or salmon calcitonin perfusion. With furosemide administration the treatment was successful in 6 of 10 patients. Furosemide was injected intravenously at the rate of 125 mg every 3 hours. With mithramycin perfusion only 2 of 8 patients have a return of the serum calcium levels to normal. With salmon thyrocalcitonin 3 of 10 patients obtained a good result. It can be interesting to suggest the association of furosemide and salmon calcitonin infusion to treat hypercalcemia of myeloma.
