Under the former division are permanent enlargements of the spleen and liver, and pigmentary matter in the blood and deposited in various organs. Under the latter are to be classed hyperæmic or even inflammatory states of the stomach and intestines, and those degenerative changes which are the consequence of continuous hyperpyrexia. The post-mortem changes which are so uniformly found as to be most often appealed to in the establishment of diagnoses are enlargements of the liver and spleen. These may be due in part to hyperplasia and in part to blood-engorgement. The brown or slate color of an enlarged liver is strongly diagnostic of malarial affections. It contrasts strongly with the yellow and natural-sized liver of yellow fever and with the negative liver of typhoid fever.
The skin is generally yellow, sometimes quite intensely icteric, but seldom showing the ecchymotic extravasations of yellow fever. In remittent fever we never find the cadaver oozing blood from the nose and the mouth, nor are the stomach or intestines ever found to contain black vomit.
TREATMENT.—The indications of treatment in remittent fevers differ from those of intermittents in two leading essentials.
First. It is a far graver form of fever, and calls for more promptitude and energy in treatment for its successful management.
Second. The important pathological condition to be combated is the hyperpyrexia, and not the cold stage, as in intermittents.
But even with a clear realization of the practical importance of these facts in governing the treatment of remittents, the practitioner must still exercise care and self-control, lest he shall unconsciously adopt the doctrine that inflammatory lesions must be present to occasion such violent pyrexia as often exists. The physician who comes directly from a case of pneumonia or rheumatic fever and finds a patient suffering from remittent fever, with temperature higher and pulse more bounding than those of the patient he has just left, is pardonable for finding it difficult to realize that these furious symptoms are not also associated with inflammation.
Attempts to cure remittent fevers by an exclusively antiphlogistic treatment either result fatally or induce long periods of confinement and suffering before recovery is reached. The great indication is to secure cinchonism as promptly and completely as possible. Nothing should divert our attention from this object. The condition of the patient as it respects fever, delirium, or state of the tongue, should form no bar to the administration of quinia. There are no practitioners who have had much experience in treating these grave forms of malarial fever after this method who are not able to recall the numerous instances of most astonishing and gratifying amelioration of symptoms as soon as saturation with quinia was brought about. The dry tongue becomes moist, the skin is bathed in gentle perspiration, the delirium ceases, and the patient sinks into a quiet sleep.
The amount of quinia necessary to produce cinchonism must be estimated for each particular case according to the measure of its severity or to states of the system more or less favorable to its absorption. It must be borne in mind, however, that questions concerning the patient's safety are paramount to those of economy. In the mildest cases I never trust to a smaller amount than from twenty to thirty grains. In violent attacks I have administered scruple doses every fourth hour until a sufficient test had been made of its capability to arrest or modify the febrile paroxysm. I have never met with any of those exaggerated physiological effects which some observers teach us to fear from the exhibition of cinchona preparations during fever. Certainly, I can declare that no permanent deafness or other lasting lesion of nerve-function has ever occurred under my observation. I must also add that I know of no reasons why remissions afford more favorable conditions for the administration of quinia, beyond the fact that the system is in a better state for its absorption and assimilation. The quinia is preferably given in solution, but may be exhibited in the form of pills, or in powder suspended in black coffee, or in the thick mucilage of the slippery elm.
The considerations of treatment which are naturally connected with those just advocated relate to measures which it may be proper to associate with the quinia. The answers to the two following questions comprise all that is necessary to be said on this point—viz.:
Are conditions of the system present which may interfere with the specific treatment by quinia, and which are not, in themselves, curable by it?
