Anomalies and Curiosities of Medicine [304]
Buckle in his 'History of Civilization' took this view, and tried to prove that the character of a people depends on their diet."
Idiosyncrasies to Drugs.--In the absorption and the assimilation of drugs idiosyncrasies are often noted; in fact, they are so common that we can almost say that no one drug acts in the same degree or manner on different individuals. In some instances the untoward action assumes such a serious aspect as to render extreme caution necessary in the administration of the most inert substances. A medicine ordinarily so bland as cod-liver oil may give rise to disagreeable eruptions. Christison speaks of a boy ten years old who was said to have been killed by the ingestion of two ounces of Epsom salts without inducing purgation; yet this common purge is universally used without the slightest fear or caution. On the other hand, the extreme tolerance exhibited by certain individuals to certain drugs offers a new phase of this subject. There are well-authenticated cases on record in which death has been caused in children by the ingestion of a small fraction of a grain of opium. While exhibiting especial tolerance from peculiar disposition and long habit, Thomas De Quincey, the celebrated English litterateur, makes a statement in his "Confessions" that with impunity he took as much as 320 grains of opium a day, and was accustomed at one period of his life to call every day for "a glass of laudanum negus, warm, and without sugar," to use his own expression, after the manner a toper would call for a "hot-Scotch."
The individuality noted in the assimilation and the ingestion of drugs is functional as well as anatomic. Numerous cases have been seen by all physicians. The severe toxic symptoms from a whiff of cocain-spray, the acute distress from the tenth of a grain of morphin, the gastric crises and profuse urticarial eruptions following a single dose of quinin,--all are proofs of it. The "personal equation" is one of the most important factors in therapeutics, reminding us of the old rule, "Treat the patient, not the disease."
The idiosyncrasy may be either temporary or permanent, and there are many conditions that influence it. The time and place of administration; the degree of pathologic lesion in the subject; the difference in the physiologic capability of individual organs of similar nature in the same body; the degree of human vitality influencing absorption and resistance; the peculiar epochs of life; the element of habituation, and the grade and strength of the drug, influencing its virtue,--all have an important bearing on untoward action and tolerance of poisons.
It is not in the province of this work to discuss at length the explanations offered for these individual idiosyncrasies. Many authors have done so, and Lewin has devoted a whole volume to this subject, of which, fortunately, an English translation has been made by Mulheron, and to these the interested reader is referred for further information. In the following lines examples of idiosyncrasy to the most common remedial substances will be cited, taking the drugs up alphabetically.
Acids.--Ordinarily speaking, the effect of boric acid in medicinal doses on the human system is nil, an exceptionally large quantity causing diuresis. Binswanger, according to Lewin, took eight gm. in two doses within an hour, which was followed by nausea, vomiting, and a feeling of pressure and fulness of the stomach which continued several hours. Molodenkow mentions two fatal cases from the external employment of boric acid as an antiseptic. In one case the pleural cavity was washed out with a five per cent solution of boric acid and was followed by distressing symptoms, vomiting, weak pulse, erythema, and death on the third day. In the second case, in a youth of sixteen, death occurred after washing out a deep abscess of the nates with the same solution. The autopsy revealed no change or signs indicative of the cause of death. Hogner mentions two instances of death from the employment of 2 1/2 per cent solution of boric acid in washing out a
