Aëtius has given the fullest account of diabetes. Upon the authority of Archigenes, he recommends at the commencement bleeding and diuretics, the latter being given to clear away the vitiated urine from the kidneys; but if the disease be of long standing, he proscribes both those measures. He recommends also a cooling diet, ruddy wine diluted, cooling applications to the pubes and loins, and, in certain cases, narcotics, such as opium and mandragora.
Alexander’s theory respecting the nature of the disease is the same as our author’s, both having borrowed it from Galen. He recommends food of difficult digestion, such as the feet of oxen, the flesh of pompions, chesnuts, &c. He forbids all saltish, acrid, and diuretic articles. He says nothing of venesection.
Actuarius recommends purgatives, in order to determine to the intestines, and astringent and refrigerant remedies in general.
Avenzoar explains fully his views respecting the nature and treatment of diabetes, in which he follows Galen closely. But the fullest and most accurate of the Arabian authorities on this subject is Avicenna. In certain cases, he admits of venesection at the commencement. The remedies, however, in which he seems to place the greatest reliance, are emetics and sudorifics, which he gives until the intention of altering the determination of the fluids to the kidneys. He particularly directs the patient to avoid taking all diuretic articles, to use exercise on horseback, moderate friction, and, in the decline of the disease, the tepid bath with fragrant wine.
Serapion gives nearly the same account as Aëtius, only he says nothing of venesection. Haly Abbas states, with his usual precision, the theory of Galen and the other Greek authorities, namely, that the disease is occasioned by a preternatural increase of the attractive faculty of the kidneys, arising from heat of the viscus. Agreeably to this theory of the disease, his remedies are refrigerants and astringents. Alsaharavius advocates similar views of the nature and treatment of the disease. When the urine is thick, with some appearances of blood, he recommends venesection. According to Rhases, the affection is connected with preternatural heat of the kidneys and debility of their retentive faculty. He says it resembles lientery of the intestines.
To those who are conversant with the principles of ancient physiology, the theory advanced by Galen, and advocated by all subsequent authorities, will appear very plausible and ingenious. The ancients appear not to have known that the urine some times possesses saccharine properties.
Rogerius, like the ancient authorities, refers diabetes to a hot intemperament of the kidneys, whereby their attractive faculty is increased. (Tr. i, 54.) All the earlier writers on medicine appear to have held the same hypothesis.
On strangury and dysuria. As these diseases arise from a variety of causes, our author has properly treated of them accordingly. We do not find that the other authorities supply much additional information.
Hippocrates mentions that there are many varieties of strangury. His remedies are the tepid bath, diluent drinks, diuretics, and anodynes.
Aëtius states that the disease is called dysuria when the patient has a desire and passes his urine with difficulty, and strangury when it is passed in drops. It is occasioned, he says, by acrimony of the urine, ulceration, or debility of the bladder. It may also arise from affections of the kidneys and liver, or from an intemperament. The treatment is to be varied accordingly.
