Hemorrhages from various surfaces have already been mentioned, and a full account given of epistaxis, which is by far the most common form. Bloody vomiting has been noticed in a small proportion of cases in various epidemics. It varies in amount, but is always attended with great gravity of the attack, and usually is followed by fatal results. It occurred in four of our cases, two of which presented also black stools containing altered blood, and suppression of urine; while in another it occurred at the close of the first relapse, and during the second relapse was copious and repeated. In this case it was attended with alarming symptoms of collapse, from which the patient rallied, and after a desperate struggle recovered.
Blood may also be discharged from the bowels in such large amount as to constitute actual hemorrhage—a symptom of great gravity; or in small quantity and completely altered, so as to impart an inky black color to the stools—a condition not necessarily attended with urgent danger; or, finally, there may be frequent bloody dysenteric stools.
Hemorrhage has also been observed from the uterus, from the kidneys, from the ears, and from the old cicatrix of a syphilitic chancre. Hemorrhage occurred in 87 out of 183 of our cases, or in nearly 50 per cent. It was from the nostrils in 82 cases, from the uterus in 1 case, from the stomach in 4 cases, and from the cicatrix of a chancre in 1 case.
Sudden collapse occurs with such comparative frequency in relapsing fever as to require special attention as one of its complications. It may occur at any period of the disease, but it is most common at the crisis of the first paroxysm or of the relapse. The symptoms are usually those of cardiac failure, with rapid, small, and feeble pulse; shallow and hurried, or slow, labored, and imperfect respiration; coldness of the extremities, while the central temperature may remain elevated; muttering delirium, rapidly passing into unconsciousness. Occasionally almost instantaneous death occurs from syncope induced by some muscular exertion, as standing up or even rising in bed. In other cases the symptoms indicate the development of cardiac thrombosis, and subsequent examination has verified this opinion. In still other cases the symptoms resemble those which occur in extreme hyperpyrexia dependent upon overwhelming and paralysis of the nervous centres. Copious hemorrhage from the stomach and nose may also induce syncope of alarming and even fatal severity. When from the latter cause, reaction may be induced and the patient may ultimately recover, as we saw in a case where after repeated hematemesis the patient sank into profound collapse. In all of its forms, however, this complication is of extreme and imminent danger, and death follows, as a rule, in a few hours. The cases in which it occurs are usually of severe type, occurring in persons who have previously been in poor health or intemperate, or who have been subjected to privation and improper exposure previous to and during the early stages of their attack. Still, collapse may occur in mild cases also, and whatever the type of the disease there may be no special indication of approaching trouble, when the patient rapidly passes into collapse, to be followed by death in a few hours. It occurred in nine of about two hundred cases under our observation. In one it was the result of hemorrhage from the stomach, and ended in recovery; in one, at the close of the initial paroxysm the patient, who was stupid, with muttering delirium, sank into collapse as the temperature rapidly fell from 105° to 97°, and died in a few hours; in one, on the fourth day of the relapse the temperature suddenly fell from 102° to 96°, with free sweating, but suddenly rebounded to 102°, with very rapid, feeble pulse, distinct basic cardiac murmur, constriction of chest, restlessness and delirium, slight convulsions, and death in eight hours; in one, a man at the end of the initial paroxysm, immediately after his admission to the hospital in apparently fair condition, became violently delirious, with bounding pulse, soon grew comatose, and died in one hour; in one, a man who was in feeble condition, on the nineteenth day, with irregular persistent fever (he had splenic abscess), sat up on the edge of the bed, sank back in syncope, and died in less than an hour; in one, a man who did well until the second day of the relapse, when pleuro-pneumonia and pericarditis were developed, died suddenly four days later: there was considerable pericardial effusion; in one, sudden death from syncope or cardiac thrombosis occurred on the twelfth day in a man who had suppurative parotitis and metastatic abscesses of the lungs; in one, sudden collapse and death occurred in one and a half hours at the end of the initial paroxysm; in one, a drunkard with large fatty liver had pyrexia continuing after the initial paroxysm, and on the ninth day, while in a state of hebetude, with mild delirium and a pulse of 112, coma suddenly occurred, and death followed in two hours.
Pericarditis is a rare complication, and is apt to coexist with pleuro-pneumonia. This combination occurred in one of our cases where pleuro-pneumonia and pericarditis were developed on the second day of relapse, and proved fatal by sudden collapse on the fifth day, with the pericardial sac distended with serum and its layers coated with plastic lymph.
Thrombosis of veins, as in phlegmasia alba dolens, occurs much more rarely than after typhoid fever. Arterial embolism, on the other hand, is not uncommon. Murchison22 reports a case in which gangrene of the left foot from obstruction of the left femoral artery, together with cerebral softening from obstruction of the left middle cerebral artery, occurred in connection with cardiac thrombosis. Zuelzer alludes to similar cases in the St. Petersburg epidemic of 1865-66, where, in addition to the extremities, the nose, ears, and lips became gangrenous. Other examples of embolism are found in lesions of the spleen and kidneys, where infarctions are of frequent occurrence.

Heart-clot, or cardiac thrombosis, appears to occur more frequently than in any other acute zymotic disease, with the exception of diphtheria. Even when the occurrence of passive hemorrhages and of ecchymoses of various tissues indicates marked dyscrasia of the blood, there will not rarely be found firm white clots in one or other of the cavities of the heart. These frequently present unmistakable evidences of ante-mortem formation, and, as already stated, there is a certain proportion of the cases of rapid and unexpected death where the fatal result is directly due to cardiac thrombosis, attended with the usual symptoms.
The constant affection of the spleen has been fully described; it is not therefore surprising that both complications and sequelæ arise in connection with it. At times, in cases which ultimately recover, the pain in the splenic region is so violent and continuous, and is attended with so much tenderness over the enlarged organ, that localized peritonitis is undoubtedly present. Occasionally this perisplenitis persists, and in conjunction with the inflammatory changes in the substance of the spleen maintains an irregular fever after the specific pyrexia has run its course. This was noticed in several of our cases, but especially so in a case where, after the initial paroxysm, an irregular fever was kept up, obscuring the relapse, until the nineteenth day, when death occurred suddenly from syncope on rising on the edge of the bed, and where examination showed splenic peritonitis, with a splenic abscess as large as a pigeon's egg.
The enlargement of the spleen usually subsides during the intermission, and disappears speedily or in the course of a few weeks after convalescence is established. Occasionally, however, it persists, and is attended with marked anæmia. In one case, where death occurred from pneumonia, the sequel of relapsing fever, at about the thirtieth day, the spleen weighed twenty-nine ounces; and in another case, where death occurred from gangrenous pleuro-pneumonia, at the fortieth day, the spleen was still enlarged and presented characteristic changes in its pulp. On the other hand, in a case where death occurred on the twelfth day of typhus, occurring forty-four days after recovery from a very bad case of relapsing fever, making it altogether the one hundredth day, none of the lesions of the first disease were discoverable.
