RESUMEN
El mercurio es un elemento metálico que ha sido catalogado como un material peligroso debido a los graves daños que ocasiona a la salud y al ambiente. La inhalación de vapor de mercurio por un periodo prolongado causa el mercurialismo, el cual es una enfermedad que se caracteriza por temblores finos y eretismo. En odontología, el mercurio es utilizado para la elaboración de las amalgamas empleadas en la restauración de los dientes tratados por caries. La intoxicación en los consultorios dentales, generalmente es de carácter crónico causada por la exposición prolongada a vapores de mercurio y ocurre por no tomar las precauciones durante la manipulación del metal en el proceso previo a la preparación de amalgama. Se ha demostrado que las buenas prácticas en el trabajo odontológico reducen los niveles de mercurio en la orina relacionados con afecciones del comportamiento. La Asociación Dental Americana (ADA) considera que los riesgos de exposición mercurial en el trabajo de Odontología son escasos si el personal que trabaja en dicha área cumple con las normas de higiene mercurial existentes
Mercury is a metallic element that has been listed as a hazardous material because of the severe damage it causes to health and the environment. Inhalation of mercury vapor for an extended period causes mercury poisoning, which is a disease characterized by tremors erethism fine. In dentistry, mercury is used for the preparation of amalgams used in the restoration of carious teeth treated. Poisoning in dental offices, is generally caused by a chronic exposure to mercury vapor and occurs for not taking precautions when handling the metal in the process leading to the preparation of amalgam. It has been shown that good dental work practices reduce levels of mercury in urine associated with behavioral disorders. The American Dental Association (ADA) believes that the risks of mercury exposure in the work of Dentistry are limited if the personnel working in that area meets the standards of existing mercury hygiene

Purity of reinfusion fluid and dialysate is mandatory in high flux, high efficiency substitutive treatments for chronic uremia, particularly when using bicarbonate concentrates. Bags of sterile and pyrogen free substitution fluid are in part responsible for the high costs of these treatments. In order to overcome these problems, the authors tested a new monitoring system (MPS-10, Gambro) for high efficiency hemodiafiltration (HDF) in which the reinfusion fluid was prepared from bicarbonate dialysate by filtration. During 5 months time, 96 on-line HDF treatments were performed in five chronic uremic patients. We found the infusion fluid and dialysate containing bicarbonate free from bacteria and endotoxins, with a correct weight balance obtained by the monitoring system. The authors believe that MPS-10 is a safe and adequate system for the production of sterile, pyrogen free dialysate and reinfusion fluid for on-line HDF, hemodialysis (HD), and hemofiltration (HF).
