Potassium iodid, although generally spoken of as a
poisonous drug, by gradually increasing the dose can be given in
such enormous quantities as to be almost beyond the bounds of
credence, several drams being given at a dose. On the other hand,
eight grains have produced alarming symptoms. In the extensive
use of iodoform as a dressing instances of untoward effects, and
even fatal ones, have been noticed, the majority of them being
due to careless and injudicious application. In a French journal
there is mentioned the history of a man of twenty-five, suspected
of urethral ulceration, who submitted to the local application of
one gram of iodoform. Deep narcosis and anesthesia were induced,
and two hours after awakening his breath smelled strongly of
iodoform. There are two similar instances recorded in England.
Pope mentions two fatal cases of lead-poisoning from diachylon
plaster, self-administered for the purpose of producing abortion.
Lead water-pipes, the use of cosmetics and hair-dyes, coloring
matter in confectionery and in pastry, habitual biting of silk
threads, imperfectly burnt pottery, and cooking bread with
painted wood have been mentioned as causes of chronic
lead-poisoning.
