Almost every purpose of sugar in the cooking of acid vegetables is served by bicarbonate of sodium or potassium. As much bicarbonate of potassium to the pound as will lie upon a quarter of a dollar will neutralize the acidity of most fruits which require a large amount of sugar to mask this property. In this manner cranberries, plums, cherries, gooseberries, red currants, strawberries, apples, peaches, and indeed all fruits to which sugar is usually added in the cooking, become available to the diabetic.
In the matter of drinks, where the patient is not on a skim-milk diet, which usually affords as much liquid as is required by the economy, little restraint need be placed upon the consumption of water, which is demanded to replace that secreted with the sugar. Instead of water, Apollinaris water, Vichy, or the ordinary carbonated water may be used if preferred, and to many they are much more refreshing by reason of the carbonic acid they hold in suspension. Apollinaris water is particularly so, and one of my patients, who recovered completely under a suitable selected diet with which this mineral water was permitted, insists that it was that which cured her.
Where a simple selected diet is adopted, tea and coffee without sugar are usually permitted. The propriety of the substitutes for sugar already referred to must be determined by circumstances.
Of distilled and fermented liquors, moderate quantities of whiskey and brandy, dry sherry and madeira, the acid German and French wines—in fact, any non-saccharine wines—may be permitted. A medical friend who reports himself about cured of diabetes writes me that he has consumed eighty gallons of Rhine wine since he began to adhere closely to a diabetic diet. On the other hand, the free use of the stronger alcoholic drinks has been charged with causing diabetes, and I have known such use to produce a recurrence of sugar. No malt liquors, except those in which the sugar has been completely converted into carbonic acid and alcohol, should be used. Bass's ale may be allowed where no especial stringency is required.
HYGIENIC TREATMENT.—The patient should be surrounded by the most favorable hygienic influences. He should sleep in well-ventilated rooms; pass much time in the open air; bathe regularly, but not in water that is very cold, and especially the body should not be long submerged in cold water, as the liver must share the general internal hyperæmia incident to prolonged cooling of the skin, and increased glycosuria may result. I have known sugar to reappear after a prolonged drenching of the skin of patients overtaken by a rainstorm. Perhaps the most suitable time for the hot or tepid bath is on retiring in winter, but in summer it may be taken on rising. Thorough friction of the entire body should be practised after the bath or independently of it. An ounce or two of sodium carbonate may be added to it with advantage, as it softens the skin and facilitates the removal of the effete epithelium. The bowels should be kept regularly open, as the effect of their confinement is to produce torpor and congestion of the liver.
Certain natural mineral waters have always enjoyed a reputation for the cure of diabetes, and notably those of Vichy and Carlsbad. The former is an alkaline water with a slight laxative tendency, and the latter a decided aperient alkaline-saline water; and it is not unlikely that they owe a part of their good effects to an action upon the liver and upper bowel. This seems the more likely because Carlsbad, which enjoys the highest reputation, contains a far larger proportion of chlorides and sulphates, which are purgative. Vichy water contains 35 grains of carbonates to the pint, and Carlsbad 11, but the latter contains twice the proportion of chlorides, or 8 grains to the pint, and ten times as much sodium sulphate, or 19 grains to the pint. They may be used as adjuvants to the treatment, a pint of Vichy or half as much Carlsbad in the morning. Being imported waters, they are comparatively expensive, and I know of no American waters which closely approach them in composition.
Of American waters, the Saratoga Vichy contains twice as much chlorides as the Carlsbad, 17.7 grains to the pint, but no sulphates. It contains about the same amount of carbonates as Vichy. It is therefore a saline-alkaline water, and may be expected to serve the purposes of Vichy and some of those of Carlsbad, for which it may be substituted. Most of the American mineral waters vaunted as useful in diabetes will be found, on comparison with these waters, to be chemically indifferent, and therefore about as useful as so much ordinary spring-water. Of the Crab Orchard Springs in Kentucky, the Sowder's spring contains 25 grains of sulphate of sodium and magnesium and 7 grains of sodium chloride to the pint, therefore about the same proportion of the two substances combined as Carlsbad; yet I am not aware that these waters have any reputation in diabetes. The waters of Bedford Springs, Pennsylvania, also approximate them in the proportion of sulphates of sodium and magnesium.
Other Saratoga waters have an undoubted action on the liver through their chlorides, and may be used in lieu of the European waters above referred to, and of the Saratoga Vichy, when these cannot be obtained; such are the Geyser spring, which contains 70 grains of chlorides to the pint, and the Hathorn, containing 63 grains.
MEDICINAL TREATMENT.—While the dietetic treatment, and especially the skim-milk treatment, of diabetes mellitus is much to be preferred for its results over an exclusively medicinal treatment, and is of itself sufficient to control, if not to cure, a large number of cases, yet instances arise in which it is insufficient to complete the removal of sugar from the urine, and there are others in which it is impossible for various causes to carry out such treatment.
In my book on Bright's Disease and Diabetes, published three years ago, I gave the preference of drugs to ergot; but since then extended opportunities have convinced me that codeia is a far more efficient remedy. Repeated comparative trials of this drug in the wards of the Philadelphia Hospital and elsewhere have satisfied me of this. The trials have been made while the patients were upon a mixed diet, which I hold to be the only fair way of arriving at a knowledge of the true value of a drug in the disease. Codeia was first suggested by Pavy in lieu of opium and morphia, which had long been used, his reason being that it did not produce the same narcotic effect. Favorable reports upon its use have been made by Foster, Image, Brunton, R. Shingleton Smith, Cavafy, Austin Flint, Sr., Harvey L. Byrd, and others. It may be given in pill or solution. One should begin with ¼ of a grain three times a day, increasing ¼ of a grain daily until the sugar disappears or the remedy ceases to have any effect, or until drowsiness is produced. Thus gradually increasing, I have reached as high as 47 grains in a day. Cavafy has given 15 grains three times daily.
