The symptomology of nervous diseases associated with lead poisoning has already been carefully set out in Chapter IX., and the pathological changes underlying these symptoms in Chapter V. Of the general treatment, little needs to be added to what has already been stated for the treatment of lead anæmia and general lead intoxication. Iron and arsenic (not strychnine, especially in presence of colic), and other similar drugs, should be employed together with iodides either as potassium iodide or as an injection in the form of an organic compound, of which there are several varieties on the market. The injection of normal serum has been advised, as well as saline injections, and in some instances venesection has been practised, but it is doubtful whether anything is to be gained by this form of treatment. Further, it has been stated that some lead is excreted through the skin, and for this reason sulphur baths, bathing in sulphuretted hydrogen water, etc., have been recommended to neutralize any lead that has gained access to the skin. Serafini[10] has claimed that by means of electrolytic baths a certain amount of lead can be found present in the water after continuous passing of a current, and it has been supposed by these observers that the lead has been actually driven out of the body under the action of the electric current. It is, of course, possible that such lead as is discoverable in the water was merely that which had already become incorporated with the patient’s skin through mechanical contact. Whatever form of treatment be adopted of a general type, the patient must certainly be removed from the chance of any further lead absorption; a person who is suffering from wrist-drop or other form of paresis should not be employed in any portion of a lead works where he may come into contact with any form of lead or its compounds for at least a year after the paresis has disappeared, and even then it is inadvisable for such a person to return to any form of dangerous lead work.
