Part 62

In one of our cases, where death occurred on the sixteenth day, apparently from double pneumonia and heart-clot, it was found that there was a rupture in the enlarged spleen near its upper end, recent plastic peritonitis in the region of the spleen, and a moderate amount of bloody pulpy fluid throughout the peritoneal cavity.

As we have seen, disturbances within the respiratory tract occur with very different frequency in different epidemics. In many they are rare, while in 1870 we noticed cough and other evidences of respiratory trouble in no less than 90 out of 200 cases.

Severe catarrhal laryngitis is a rare and dangerous complication. It did not occur in our cases, but both Begbie and Paterson report cases of it which required tracheotomy, and Wyss and Bock met with ulcerative laryngitis with perichondritis.

Bronchitis of moderate severity, although rare in many epidemics, {404} occurs so frequently in others, as in Philadelphia in 1870, as to rank as a symptom of the disease.

Pneumonia is one of the most fatal complications. The results of our own observations agree with the statements of Jenner and of Carter, that it is the next most common lesion after enlargement of the liver and spleen. On the other hand, Murchison noted it only in 4 or 5 out of 600 cases. It occurred in at least 11 of our cases, 8 of which were fatal; and unquestionably less extensive inflammation was present in other cases which recovered, in view of the marked respiratory disturbances frequently present. Both lungs were involved in 4 cases; of the remainder, the right and left were about equally divided. Out of 23 autopsies, the lesions of pneumonia were found 8 times. The lower lobes were affected in every case. The form of this disease was croupous in 9 cases; in 1 it was that of metastatic suppuration, and in 1 it was more properly described as splenification. The amount of plastic pleurisy associated with it was usually great, and in one case there was also severe pericarditis. In another case the disease advanced to the stage of gangrene of a circumscribed area of the pleura and of the superficial layer of the lung. In only one instance was albuminuria present. In two cases the pneumonia occurred so late in the course of the disease that it might be regarded as a sequel. Death occurred in one of these on the thirtieth day, and in the other (that in which gangrene ensued) it ran a subacute course, and death did not take place until the fortieth day. In the other cases the disease began at the close of the initial paroxysm, during the intermission, or early in the relapse. As would be expected, the sympathetic fever due to this complication modified and obscured the characteristic course of the specific pyrexia.

This rare termination in gangrene has been noted by other observers; in all five or six times. Parry met with a truly remarkable case of double pneumonia, followed by gangrene, and yet resulting in recovery. Jaundice is apt to attend cases of relapsing fever which are complicated with pneumonia.

Pleurisy is an almost constant accompaniment of pneumonia, and frequently occurs in marked degree. It may also be present in cases of severe splenic inflammation. In all probability, localized plastic pleurisy is not infrequent, and may cause some of the severe thoracic pains so frequently present.

Metastatic abscesses of the lung occur occasionally as a result of the profound toxæmia, and are apparently preceded by patches of infarction, which soften in the centre, as in the usual development of pyæmic abscesses. This condition was found in one of our cases in conjunction with suppurative parotitis. It has been included among the instances of pneumonia.

Acute miliary tuberculosis, involving chiefly the lungs and intestinal canal, occurred as a sequel in one case under our observation, and phthisis has been found to follow by other observers (Carter). It is to be expected that if the patient did not so quickly pass from under observation it would be found that an affection so gravely complicating nutrition as does relapsing fever is frequently followed by serious organic disease.

Parotitis is mentioned by so few authors as to show that it is a {405} rare complication in most epidemics, varying from 1 in 600 to 1 in 50 cases. One gland only is affected at a time as a rule, though both may be involved successively. The inflammation begins either during the intermission or the relapse, and may terminate by resolution or by suppuration. Although a painful and severe complication, it is followed by recovery in a considerable proportion of cases. Carter states "that in some degree it was noted in 2 or 3 per cent. of all cases, and nearly as often amongst survivors as in the casualties." It occurred in three of our cases (185); once it underwent resolution; once suppuration occurred in the parotid and in the masseter muscle, with metastatic abscesses in the lungs, and death; and once the patient, who had previously existing amyloid degeneration of liver and spleen without albuminuria, had severe relapsing fever with two relapses, in the first of which parotitis occurred in both glands, successively terminating in suppuration, after which he did well through an apyretic period of six weeks, when sudden high fever appeared, followed by speedy death.

Pharyngitis and tonsillitis of mild grade occur in from 3 to 25 per cent. of the cases in different epidemics.

Hiccough deserves to be ranked among the complications, because it is of frequent occurrence, obstinate and annoying. It occurred in a considerable proportion of our cases, and much more frequently in those who had jaundice. It was often present both in the initial paroxysm and in the relapse, but disappeared soon after the end of the pyrexia. It bore no constant relation to the severity of the vomiting. Not rarely it lasted several days and nights, causing exhaustion and interference with sleep and proving rebellious to treatment. Hypodermic injections of morphia and atropia, chloroform internally, and extremely careful alimentation proved most serviceable.

Hemorrhage from the stomach has already been spoken of (see p. 390).

Diarrhoea, as already stated (see p. 390), occurs much more frequently than in typhus fever, varying from 1 per cent. (Murchison) to 15 per cent. (Scotch epidemics) or 33 per cent. (Philadelphia), or even 50 per cent. (Königsberg). It is usually of moderate severity, but occasionally is so profuse and intractable as to constitute the main cause of death. In some epidemics the attacks of looseness occur almost exclusively after the relapse, but in others the bowels are frequently loose during the febrile stages. In our cases there were not infrequently from three to eight thin, dark, bilious or light yellowish stools daily after the second or third day of the initial paroxysm, and then the looseness would stop during the intermission, probably to recur in the relapse. Occasionally diarrhoea with very frequent liquid stools occurs at the close of one or both of the febrile stages, assuming a critical character, and substituting more or less of the sweating which is the common mode of crisis, although in several such cases quoted by Murchison from Douglas the sweating, despite the critical diarrhoea, was usually profuse. It can scarcely be said that there is any relationship between diarrhoea and vomiting; both are frequently present, and may even be severe and persistent in the same case, though either may be marked while the other is moderate or slight. Abdominal pain and tenderness in the epigastrium and hypochondria are constant symptoms, but when diarrhoea is marked there are apt also to be griping {406} pains and tenderness in the lower segment of the abdomen. When diarrhoea occurs as a sequel, either beginning after the close of the relapse or continuing in cases where the bowels have been loose during pyrexia, it is apt to prove obstinate and intractable, or even to lead to a fatal result.

The character of the stools varies much; usually thin and dark, they may be light yellowish or even whitish. Thus, in a severe case with deep jaundice we observed seven liquid and decidedly whitish stools in twenty-four hours. In such instances there is undoubtedly more or less complete closure of the biliary ducts by plugs of mucus or by swelling of the mucous membrane. On the other hand, the stools may be inky black from admixture with altered blood, or, lastly, they may consist of mucus and blood, in which event the complication assumes the form of actual dysentery and is attended with increased abdominal pain and with tenesmus. Dysentery was, as would be expected, quite frequent in the Indian epidemics studied by Carter. It is usually of moderate severity, but occasionally it runs into gangrenous inflammation, is attended with perforation of the bowel, or is followed by hepatic abscess. In one instance we noticed a peculiarly fetid puriform discharge from the anus, which occurred during the relapse and persisted for several weeks, gradually subsiding, as though from some unhealthy ulceration which slowly healed.

Jaundice is of frequent occurrence, but has been sufficiently discussed at page 391.

Peritonitis is not rare in its circumscribed form. This statement is based on the comparative frequency with which localized splenic peritonitis, of varying degrees of severity, is found after death in relapsing fever from various causes, and from the great frequency of severe pain and tenderness in the region of the enlarged spleen in favorable cases. In its lesser degrees it may not add materially to the danger of the patient, but in more severe forms, associated with serious splenic lesions, it may run a protracted subacute course and maintain irregular fever.

General peritonitis is, on the other hand, a rare complication, occurring not more than once in several hundred cases. It results from dysenteric perforation of the bowel, from rupture of a splenic abscess, or from rupture of the spleen itself. An example of this latter accident which occurred under our observation has already been given. Speedy death invariably follows, though in the case just referred to the symptoms of peritonitis were totally masked by those of the coexisting double pneumonia, which seemed to be the immediate cause of death.

Suppuration of the mesenteric glands is a rare complication, mentioned especially by Wyss and Bock. As these glands are not usually found enlarged, there being no irritative lesion of the intestines of common occurrence in relapsing fever, it is probable that the collections of pus which have been found were metastatic in origin.

Dyspepsia is not an infrequent sequel, as would necessarily be the case after a disease characterized by so much gastric irritation and by such serious lesions of the liver and spleen. As a consequence, care in diet is often required for a considerable period after the course of the disease has ended; dyspeptic symptoms are frequently complained of, and marked emaciation and anæmia often protract convalescence.

{407} It may be observed that a striking appearance of emaciation is often developed shortly after the crisis of the first paroxysm, or, more particularly, of the relapse. It is partly due to the actual loss of weight during the high pyrexia, but even more to the abrupt transition from a state of extreme febrile turgescence to one of equally extreme relaxation and maceration of the surface.

The amount of urine has been seen (p. 387) to vary greatly in cases distinguished by no special disorder of the kidneys; the extremes in ordinary cases being from twelve or fifteen ounces just before the crisis to from eighty to one hundred and twenty within forty-eight hours after the crisis. Suppression is, however, sometimes noted, and is always a grave symptom, though Parry reports more than one case in which on several successive days there was not more in twenty-four hours than one fluidounce of non-albuminous urine, and in which no symptoms of uræmia occurred, and the sweat had no urinous odor. In one of our fatal cases, with intense jaundice, hematemesis, inky black stools, and oedema of the feet and of the lungs, there was not a drop of urine secreted during the last four days of the initial paroxysm; death occurred on the eighth day, and the kidneys were found intensely engorged, of a deep blackish-blue color, with numerous ecchymoses in the cortex, due to impaction of the convoluted tubules with blood, while the renal epithelium was granular and swollen, and many tubules were filled with epithelial cells and granular matter. At the autopsy the urinary bladder was firmly contracted and contained a very small amount of bloody liquid.

More frequently, incontinence of urine, with or without retention, occurs during the febrile stages--according to our observation, most commonly in cases attended with mental disturbance and tending to a typhoid condition. The symptom was not of very grave significance, however, and after the use of the catheter for a few days the bladder regained its tone.

Albumen is quite frequently present in small amounts during the pyrexia of relapsing fever. Thus, in 18 cases of ordinary severity, which all recovered, and in which the urine was carefully examined daily, a trace of albumen was found in 5; in 2 cases it appeared both in the initial paroxysm and in the relapse, but in all instances its presence was of brief duration. In one of these five cases the albumen appeared at both critical periods, when the amounts of urine in twenty-four hours were respectively 150 ccm. and 250 ccm.; but in the other cases the transient albuminuria coincided with free secretion of urine (1250 ccm., 1850 ccm.). It is probable that were the same careful search to be made in all cases the presence of albumen would be detected in fully 20 to 25 per cent. On the other hand, in fatal cases the occurrence of albuminuria is by no means constant, although undoubtedly it is present in a larger proportion of such cases than of those of ordinary severity.

Our experience does not confirm that of Murchison, who states that he never met with typhoid symptoms in relapsing fever without albuminuria or some other evidence of retarded elimination by the kidneys. In several of our cases where the typhoid state was developed in the highest degree repeated examination of the urine failed to discover albumen.

{408} Most observers have been struck with the comparative immunity of the kidneys from serious disturbance in a disease presenting such complicated morbid processes and widespread lesions as relapsing fever. To show, however, that these organs suffer specially in certain epidemics, it may be mentioned that Obermeier reports having found albumen with tube-casts of various kinds in 32 out of 40 cases of relapsing fever, thus showing that, in the particular epidemic he was studying, catarrhal nephritis was of almost uniform occurrence. It is true that serious interference with the elimination of urea and other nitrogenous matters may occur without the coexistence of albuminuria, so that it is impossible to deny that severe nervous symptoms may result from impaired renal activity even when the urine contains no albumen.

Attention has already been called to the variations presented in the amounts of urea, but more extended observations are required to show the precise relations of these variations to the graver nervous phenomena. It will be found, we venture to opine, that, while in one group of relapsing-fever cases of grave type, cerebral symptoms are dependent upon the retention and accumulation in the system of urea and other effete nitrogenous products, owing to interference with renal activity from pre-existing organic disease of the kidneys or from an exceptional degree of congestion of those organs, there are other groups where similar typhoid cerebral symptoms are more directly dependent upon the specific toxæmia, upon the hyperpyrexia, upon exhaustion of the nerve-centres by intense peripheral irritation, or upon congestion or other morbid conditions of the nerve-centres themselves.

In all cases where cerebral symptoms manifest themselves in relapsing fever the daily examination of the urine--which here, as in other zymotic diseases, is a duty in all cases--becomes of extreme importance. Three conditions should be borne in mind in such examinations. In the first place, the attack of fever may have occurred in one already the subject of organic kidney disease, and, considering the classes from which the majority of the cases of relapsing fever are drawn, this possibility cannot be of rare occurrence. Out of eighteen post-mortem examinations in which the kidneys were studied with especial care we found positive evidence of pre-existing organic disease four times. In these cases the albuminuria was marked and persistent, though tube-casts were rarely found, and severe cerebral symptoms of typhoid type were prominently present. In another highly interesting case the patient, who had amyloid disease of the liver, spleen, and kidneys, contracted severe relapsing fever; he had increased albuminuria during both febrile stages, suppurative parotitis, but no grave cerebral symptoms, and apparently recovered. After an apyretic period of six weeks, during which the symptoms of the amyloid visceral disease persisted, a sudden and rapidly fatal pyrexia occurred. Unfortunately, the existence of spirillar infection of the blood was not known at the time.
