SECT. XXXII.—DIAGNOSIS OF HECTIC FEVERS.
The hectic fever is not only seated in the fluids and spirits, but also in the solid parts. It is unaccompanied with pain, and those affected with this fever imagine that they have no fever at all, for they are sensible of no heat, all the parts being heated equally. There are two kinds of hectic fevers, the one for the most part supervening upon ardent fevers which have been protracted so long as to consume in time all the juices in the body of the heart; the other may come on while it remains plentiful. The former constitute not only hectic but marasmus. Those that come on while the juices of the heart remain, seize upon the body of the heart, and hence the febrile flame is kindled, like the flame of a lamp from its wick. This is one of the modes of formation. The other mode is, when they make their attack originally, commencing like ephemeral fevers, from grief, anger, or much fatigue attended with heat. These may be cured without difficulty; but those of them which have terminated in marasmus, it is impossible to cure. A hectic fever which is running into marasmus may be easily recognized. You may see the patients’ eyes immeasurably hollow, dry rheums determined to them, and they have a certain squalid appearance. The vital bloom of their colour is gone; their forehead is parched and stretched; they constantly wink as if asleep, and yet the affection is not sleep, but an inability to keep awake; their temples are collapsed; and what remains, but the bones and skin alone? If you lay bare, and examine the parts about the abdomen, you will fancy that none of the entrails and intestines remain, and that the hypochondrium is forcibly drawn upwards. The skin is parched in the last extreme, the pulse slender, dense, and hard. The heat on the first application of the hand seems faint, but soon afterwards feels acrid and pungent. While, therefore, any of the natural moisture remains, the fever is only hectic; but when the humidity runs the risk of being altogether consumed, a true marasmus is formed.
Commentary. Our author has copied from Oribasius (Synops. vi, 21), who in his turn is indebted to Galen (de Diff. Feb. i, 11.) A similar account is given in somewhat fuller terms by Aëtius (v, 92.) See also Alexander (xii, 4.) We shall merely give his explanation of the characters of the pulse. It is hard and small, because the vessels have become dry and contracted; it is dense (frequent?) because the necessities of the system require it to be so, (namely, in order to make up for the reduced expansion of the artery); it is feeble, owing to the weakness of the vital powers; and slender, because the vessel does not admit of being stretched in breadth. Nonnus and Actuarius derive their views from Galen. According to the latter, hectic fever is a very dangerous disease when it arises from the conversion of any other fever, but when connected with inflammation or scirrhus of any vital organ it is almost incurable. Palladius says that the hectic is an unceasing fever, wasting and consuming the natural humidity of all the members, and supervening for the most part upon acute and ardent fevers, but sometimes arising from sympathy with some vital organ. He states it as a characteristic of the hectic fever, that food increases the febrile heat, in like manner as water poured upon unslacked lime enkindles heat. This comparison is borrowed from Galen, and is repeated also by Alexander and Nonnus. Palladius, like our author, represents marasmus as the termination of the hectic fever. It is distinguished, he says, by prostration of the natural faculties, aridity, and wasting of the body, which becomes dried and parched like a tree deprived of its juices by exposure to excessive heat.
According to Haly Abbas, hectic fevers commonly arise either from the conversion of semi-tertians, or from abscesses of the lungs, whence heat is sent to the heart, and from it is diffused over the system. (Theor. viii, 7.) Alsaharavius states that hectic fevers arise from protracted ephemeral or putrid fevers, or from sympathy of the system with ulceration of the lungs, bladder, or liver, or from any chronic and prolonged disease. (Pract. xxxii.) Averrhoes represents the hectic as supervening upon ephemeral and putrid fevers. He ridicules the comparison of the effects of food on the febrile heat to those of water poured upon lime. (Collig. iv, 33.) Avenzoar gives the same account of hectic as our author. (iii. 3, c. 13.) Serapion’s account, although borrowed from the Greeks, is distinct and curious (vi, 11.) See also Rhases (ad Mansor. x, 3, alibique.) He and Haly Abbas repeat the graphic delineation of a person in the last stage of hectic fever, borrowed by our author from Galen, who seems to have had in view a similar description of a person sinking of consumption, given by Aretæus. (De Morb. Chron. i, 8.) Avicenna’s account of the nature and causes of hectic fevers is so ample, that we regret our limits will not permit us to do justice to it. The principal causes of them which he enumerates are ephemeral and putrid fevers, and abscesses of the lungs and liver. The pulse, he says, is hard, small, frequent, and weak, and may become myurus, if the fever pass into the state of marasmus. He gives, principally from Galen (de Marasmo), an interesting description of what he calls the hectic of old age, but which Galen calls old age from disease. Its symptoms, as described by these authors, are coldness and aridity of the body; the pulse slow, small, and rare, unless very weak; the urine white, thin, and watery. (iv, 1, 3.) Franciscus de Pedemontio, a writer of the fourteenth century, in like manner pronounces the hectic of old age to be a dry intemperament of the system, and recommends for it a calefacient and moistening regimen.
