The Arabians call it massera. Phlegmon of the brain, according to Haly Abbas, is attended with swelling of the brain, so as to occasion a separation at the sutures, redness of the face, acuteness of vision, and sympathetic affection of the stomach. He recommends bleeding at the arm, cooling laxatives, applications of cold things to the head, and so forth. The translator of Alsaharavius calls it ‘flegmon’ and ‘apostema in cerebro;’ says it is occasioned by a collection of corrupted blood in the vessels of the brain; and directs general bleeding, opening of the nasal vein, or of the sublingual. Avicenna’s account is nowise different from our author’s.
Hippocrates makes mention of sphacelus of the brain, which, he says, generally proves fatal in three days. (Aphor. vii, 48.) From the Commentary of Galen it would appear that by sphacelus he meant that state which is the result of an extreme degree of inflammation. Another of his commentators, Theophilus, states that by sphacelus was meant incipient mortification. (Ed. Dietz, ii, 537.) It was therefore a species of ramollissement. See an elaborate disquisition into the nature of the sphacelus of Hippocrates by Dr. Coray. (Ad Hippocrat. de Aer. &c. 64.)
SECT. VIII.—ON ERYSIPELAS OF THE BRAIN.
Erysipelas occurs also in the brain, and the patient suffers in the following manner: he has pain of the whole head, and feels as if there were fire in it; his face is cold and somewhat pale, and his mouth dry. Wherefore, bleed such a patient, and more particularly abstract blood from the veins under the tongue, and apply cooling things, such as we use in other kinds of erysipelas.
Commentary. Aëtius, Oribasius, Avicenna, Haly Abbas, and Alsaharavius treat of this disease in much the same terms as our author. Haly says there is less heat of the face than in phlegmon, nay, that the face even feels cold. Alsaharavius describes it as being accompanied with violent pain, much inflammation, and blackness of the face. He approves of the depletory treatment in general.
SECT. IX.—ON LETHARGY.
Lethargy, which is a lesion of the rational part, has the same seat as frenzy, I mean the brain, but the matter which causes it is of an opposite nature; for it is occasioned by a humid and cold phlegm irrigating the brain. It is attended with an obscure fever, which is not very pungent, and with somnolency. The pulse is large, rare, and undulatory; the respiration is very rare and weak. Lethargies are altogether disposed to sleep; are roused with difficulty; can scarcely be made to answer questions; are forgetful and delirious; they yawn frequently, and remain sometimes with their jaws distended, as forgetting to shut their mouths; their evacuations by the belly are generally watery, but sometimes, on the contrary, the belly is dry; their urine is like that of cattle. Some have tremblings and sweatings. Carus being occasioned by the same matter as lethargy differs from it in this, that fever precedes carus and is more violent, whereas it is subsequent in lethargy; and in this respect also, that carus often supervenes upon other complaints, for it often follows paroxysms of fevers, epilepsy, and compression of the brain, as from the bone in fractures, or from the meningophylax pressing upon the anterior ventricle of the brain; whereas lethargy has a certain peculiar formation.
The cure of lethargy. When the strength permits, we must open a vein; but, when it does not, we must use acrid clysters. We must also lay the patient in an apartment of large size, and having a moderate degree of light, and apply to the head an embrocation of oil to which castor has been added. Some, instead of the oil, use vinegar and rose-oil with the castor, by which they strengthen and warm the head at the same time. And, having anointed the rest of the body, particularly the extremities, with old oil, they stimulate them with calcined nitre, pellitory, pepper, or the granum cnidium. It is also possible, by making them into cerate with castor, to use them in this way. We must likewise apply strong-scented things, triturating thyme, marjoram, and pennyroyal, with vinegar. We may smear the mouth and palate with mustard pounded in a small quantity of honey, and we may even remove with the fingers the phlegm which adheres to it. And, if they will admit it, it is proper to use a masticatory consisting of oxymel with hyssop, pennyroyal, marjoram, or mustard itself. We may give also in their drink things of a diffusible nature, more particularly the diospolites, to the amount of a spoonful, with oxycrate. When there is chronic trembling, we must give two or three scruples of castor; or, if there be a redundance of humours, and there be nothing to contra-indicate the use of it, we may add a scruple of scammony to the castor. When the disease is protracted, the head must be shaved and fomented with salt, millet, and the like, in small bags; and sinapisms are to be applied to the whole head, and medicines used to excite sneezing. Afterwards we may apply dry cupping, with much heat, or cupping with scarifications, to the back part of the head. It will be necessary to attend to the natural evacuations by means of clysters and diuretics. Apply to the lower part of the belly an embrocation with oil of rue, or Sicyonian oil with some castor. We must also attend particularly to the deglutition, injecting, by means of a vessel with a narrow mouth, warm water, to which has been added some sweet potion, more especially apomel. And, if there be inflammation in the intermediate parts, we must cure it with embrocations and cataplasms. To the nose is to be applied mustard triturated with vinegar, or burnt castor. Their food should consist of ptisan, or the decoction of oats, or that of alica, with oxymel, salt, or pennyroyal, sometimes giving of it every day, and sometimes only every alternate day. After food, ligatures are to be applied to the extremities, which may also be bent back; and the limbs are to be pinched; and sometimes we may even tear the hair violently in order to rouse them. Rubefacients to the thighs and legs are also proper. When the affection is in the decline, we may enjoin suitable gestation, direct the bath to be taken, and a restorative regimen to be used properly.
