BRIGHT'S DISEASE.
This affection may appear in either an acute or chronic form. The acute form is frequently a complication, or sequel of scarlet fever, diphtheria, cholera, typhoid fever, erysipelas or measles, and is frequently developed by intemperance. The acute form of the disease is very rapid in its progress, often destroying life by uræmic poisoning—the retention of urea in the system.
The symptoms of the acute form are diminution or suppression of urine, dry skin, chills, thirst, pains in the loins, and a general dropsical, puffy condition of the system, especially manifesting itself in the earlier stages under the eyes, but gradually showing itself in the oedema, or swelling of the feet, and lower extremities generally. Unless promptly relieved, the patient dies of coma (stupor), or from convulsions. No person should be so rash as to attempt the treatment of this dangerous affection without the aid of the best medical skill that can be procured.
It is the Chronic Form of Bright's Disease that we propose principally to discuss in this article. True Bright's disease of the kidneys is an insidious and most fatal form of organic disease.
We venture to assert that less than one per cent. of those who imagine they have "Bright's," have this disease at all. We find that most of those who, as one of our Faculty puts it, insist upon having Bright's disease, base their "diagnosis" upon the ever-changing condition of the urinary secretion, and especially upon the copiousness of the deposit; whereas, in true Bright's, deposits of any kind are rarely met with. Perhaps the form of deposit most commonly mistaken for Bright's disease, is that known to medical men as the urates. When the urates are in excess they form a heavy pinkish deposit of a flocculent nature within from five to thirty minutes after the urine has been passed—that is, after it has been passed sufficiently long to cool. To prove that the deposit is urates, heat the specimen to the temperature of the blood, when the deposit in question will disappear. Excess of urates has now been definitely traced, in the majority of instances, to functional torpidity of the liver.
Another common form of deposit is that in which the reaction of the urine, instead of being acid, as in health, is either neutral or alkaline, and in which the earthy phosphates are precipitated for this reason. The earthy phosphates, when thrown down by a neutral or an alkaline condition of the urine, appear as a heavy white deposit, which, though usually devoid of clinical significance, is certainly calculated to frighten timid patients who read of the "terrible ravages of Bright's" in the advertisements of various popular "kidney cures." To prove that the precipitate is phosphatic in its nature, add a few drops of vinegar and it will disappear; whilst, if, after the vinegar has been added, the specimen be brought to the boiling point, not only both the urates and phosphates remain in solution, but there is only one single substance known to pathological chemistry that can form a deposit under these conditions—and that substance is albumen, which, if present in quantity, is always indicative of serious disease.
The papers are filled with the plausible but unwarranted statements of the manufacturers of various "kidney cures," who anxiously desire that every one should be impressed with the idea that all their troubles arise from kidney disease in order to sell large quantities of their medicines. In many cases the unfortunate patient is rendered much worse by the use of remedies that are not suited to his condition, and which will not cure the real trouble with which he is affected.
Daily we are consulted by persons in whose cases these errors have been made. In reality, true Bright's disease is not a common affection, and nine out often individuals who think that they suffer from it, or the early stages of the trouble, in fact have something more curable. In some cases it is an affection of the liver, which forces an excretion of unnatural salts by the kidneys, and thus renders the urine acrid and irritating, or they may be suffering from some other disease, such as a deformity or enlargement of certain glands, as the prostate; unnatural position of the organs, as with women who suffer from weakness, the uterus pressing forward on the bladder and urethra, and thus showing every evidence of disease in the urinary canal. It is as common for persons to suffer from deformity of the urinary canal as from misshapen limbs, or from noses and ears not of proper size and proportion.
The urinary canal, from the bladder outward, is narrow and delicate. Any disease or injury therein is liable to result in gradual contraction, which may be manifested long years after the cause has been forgotten, or has disappeared. These affections, to the inexperienced, or the physician who is not particularly alert and cautious in his diagnosis, are liable to cause error, and he will pronounce a given case Bright's disease, when in reality there is some simple cause for the irritation of the urinary canal, and the pains in the kidneys, etc., all of which frequently result from a slight damming up of the flow of water, and the prevention of free expulsion from the system of the salts of which the body is relieved by the kidneys. They cannot work under pressure. When, from any cause, the flow of water is checked, and, as it were, dammed up so that a slight pressure is put upon the kidneys below, their secretion is most materially interfered with, and the many trains of symptoms that usher in disease of the kidneys, appear.
The true, and only sure way to relieve these conditions, as can be understood by any one, is to remove the real cause. The use of any medicine that stimulates the kidneys to an irritable action, under such pressure, is to be avoided, as it only makes the trouble worse, increases the amount of water that is dammed up, and results in more serious manifestations of constitutional disease; whereas, by merely relieving the choked outlet, the flow of water becomes free, and the kidneys are speedily restored to their natural condition. This is well illustrated by the following:
