Strategies for epidemiologic studies of lead in bone in occupationally exposed populations.

The Epidemiology of Lead Toxicity in Adults: Measuring Dose and Consideration of Other Methodologic Issues

We review several issues of broad relevance to the interpretation of epidemiologic evidence concerning the toxicity of lead in adults, particularly regarding cognitive function and the cardiovascular system, which are the subjects of two systematic reviews that are also part of this mini-monograph. Chief among the recent developments in methodologic advances has been the refinement of concepts ...

ORGANOPHOSPHATE-INDUCED CHRONIC TOXICITY IN OCCUPATIONALLY EXPOSED WORKERS

Organophosphate chronic toxicity has been evaluated in this study. Biological screening for organophosphate insecticide-exposed workers is mostly recommended for mixers, loaders, formulators and spraymen. We have studied 17 occupationally exposed persons to pesticides. Using Ellman's colorimetric method, their plasma cholinesterase activities have been measured. Results show that the appear...

The Potential Genotoxic Effects of Antineoplastic Drugs in Occupationally Exposed Nurses

Using Ineffective Coping Strategies for Facing With COVID-19

   Dear Editor, Methods that people use to overcome problems are called coping strategies. The concept of coping was first introduced by Lazarus in 1966. He believed that stress involves three stages. First, there is the initial assessment, which is to observe a risk. The second stage involves the evaluation, which is the search for an answer in the mind, and the third stage is to f...

An improved instrument for the in vivo detection of lead in bone.

An improved instrument for the fluorescence excitation measurement of concentrations of lead in bone has been developed. This is based on a large area high purity germanium detector and a point source of 109Cd. The source is positioned in a tungsten shield at the centre of the detector face such that 88keV photons cannot enter the detector directly. In vivo measurements are calibrated with plas...
