222 POISONING. 



The lesions are those of gastro-eiiteritis, the intestine l)eing empty, 

 and its mucous membrane of red colour. 



Treatment is confined to administering drugs Hke camphor, rice, 

 bismuth, opium, chloral, and emollients, which diminish peristalsis and 

 lessen secretion. 



IODOFORM POISONING. 



The causes are limited to the licking of wounds which have been 

 dressed with iodoform. 



The symptoms include gastric disturbance, somnolence, coma, and 

 the signs of iodism. 



The only lesions are those of fatty degeneration of the kidneys and 

 liver. 



Treatment comprises the exhibition of vomitants, stimulants, and 

 diuretics. 



IODINE POISONING : IODISM. 



Death by iodine poisoning is absolutely exceptional : the complications 

 described under the name of iodism are rather to be referred to satura- 

 tion of the organism than to true poisoning. 



The cause of iodism is unduly prolonged administration of iodide of 

 potassium, or of iodine in solution. 



The symptoms include discharge from the eyes, coryza, hypersecre- 

 tion from all the mucous membranes, and gastric disturbance. The 

 cutaneous eruption exhibits special peculiarities, including desquamation 

 of the epidermis in the form of bran-like scales, and pruritus. 



The first indications in treatment are to discontinue the drug and to 

 administer stimulants and nutrients like milk, cod-liver oil, etc. 



STRYCHNINE POISONING. 



Strychnine poisoning is most commonly due to over-doses of the drug 

 accidentally given during treatment. 



The symptoms comprise tetanic convulsions, hyperaesthesia and 

 dyspnoea. As a result of muscular rigidity, the ribs cannot be moved, 

 and death by asphyxia follows. 



Treatment comprises the use of anaesthetics, and the administration 

 of chloral hydrate, as long as the contractions continue. Bromide of 

 potassium, tobacco, tannin, etc., are also useful.
