Another radiographic sign of elevated lead levels is the presence of radiodense lines called lead lines at the metaphysis in the long bones of growing children, especially around the knees. [212] These lead lines, caused by increased calcification due to disrupted metabolism in the growing bones, become wider as the duration of lead exposure ...

Langer punctured numerous holes at short distances from each other into the skin of a cadaver with a tool that had a circular-shaped tip, similar to an ...
