Bad air and bad food are also important predisposing causes. They are

conditions to which the children of the poor, especially in large

cities, are constantly exposed. Insufficient protection from climatic

influences, neglect of person, and unhygienic surroundings must be

classed in the same category. It is claimed that vitiated air,

unwholesome habitation, {1186} insufficient or improper food, squalor

and filth may cause the constitutional tendency, as they will certainly

precipitate the development of the disease in those predisposed to it.

Exciting Causes.--The border-line between the predisposing and exciting

causes cannot be positively fixed. The presence of tuberculosis or of

some form of scrofulous disease in some other part of the body so

constantly precedes the development of tuberculosis of the mesenteric

glands, even in those who have not exhibited the characteristic

phenomena of the scrofulous diathesis, that such affections must be

regarded as exciting as well as predisposing causes. No one can doubt

the frequent infection of the mesenteric glands in cases of pulmonary

tuberculosis. The probability of systemic infection from a single focus

is universally admitted. These facts and circumstances do not exclude

the possibility of localized tuberculosis of the mesenteric glands.

Whether such exclusively local development of tubercles ever occurs

independent of the scrofulous diathesis cannot be determined, but that

the disease does find its exciting cause in inflammatory conditions of

the intestinal mucous membrane cannot be doubted. Schüppel, who asserts

the primary development of the tubercle-formation in lymphatic glands,

does not claim an idiopathic origin, but admits the necessity of a

primary peripheral irritation in direct connection with the affected

gland. The intimate connection between diseases of the intestinal

mucous membrane and of the mesenteric glands is established beyond a

doubt. Vogel and Steiner assert that tabes mesenterica is a common

result of enteritis folliculosa. A primary inflammatory process may not

contain any element which could be classed as tubercle, yet it may

excite secondary tuberculosis of the glands. Whether such a result only

occurs in those who may have acquired or inherited the predisposition

is yet undecided. In many of the cases of tabes mesenterica tuberculous

ulcers are found in the intestines, but it cannot be claimed that such

ulcers are always the primary foci of tuberculous development. If

primary, it is not difficult to understand how the virus may be

transmitted to the glands.

It has been claimed that certain articles of food will produce the

disease. Potatoes and rye bread in large quantities and a coarse

vegetable diet have been mentioned among the exciting causes.

Deficiency in the quantity of food is a much more frequent cause than

inferiority in quality, yet there can be no doubt that any and every

article of diet that will set up catarrhal inflammation of the

intestinal mucous membrane may become a cause. Irritation of the mucous

membrane of the alimentary tract, induced by coarse, stimulating, or

imperfectly-digested food, or by the improper and frequent use of

purgative medicines, may give rise to disease of the glands; and, even

though the irritation may in itself be trivial, its long continuance or

frequent renewal may prove sufficient, especially in those in whom the

predisposition is present. Malarial and exanthematous diseases have

also been considered exciting causes, and among the latter class

measles and scarlet fever, because of the inflamed condition of the

intestinal mucous membrane which they leave, are the most frequent.

Difficult dentition and whooping cough must also be classed in this

category.

Recently attention has been called to the probable transmission of the

disease through the milk of diseased cows, but further investigation

and {1187} more reliable data are necessary to establish this

connection. Klebs has deduced the conclusion from recent experiments

that the use of the milk of cows in advanced phthisis will always

produce tuberculosis, which begins as an intestinal catarrh and extends

to the mesenteric glands.

Some of the older authors believed that the cure of some chronic

diseases of the skin and mucous membranes and the suppression of

chronic discharges might induce tuberculosis of the mesenteric glands;

but these conditions are now known to be most frequently the initial

manifestations of the scrofulous diathesis, and the mesenteric

complications are far more likely to occur when these primary foci are

neglected and the patient is left to suffer the unabated progress of

the disease.

MORBID ANATOMY.--It is not usual to find all the glands of the

mesentery affected at once, nor of those affected all in the same stage

of disease. Newly-affected glands may be found alongside of others in

an advanced condition. In the first stage the glands are enlarged, but

rarely exceeding the size of a filbert; they are firm, but not

inelastic. This change consists in hyperplasia of the

gland-constituents. Microscopic examination shows abundant

cell-proliferation, but the cells are badly constructed and prone to

undergo retrogressive metamorphosis. The cells accumulate in clusters

without any intercellular substance, and compress the lymph-sinuses and

blood-vessels.

The second stage is characterized by the commencement of the cheesy

degeneration. The glands enlarge and coalesce in clusters, sometimes

forming large masses of hardened and inelastic glands. On section they

exhibit in the beginning foci of cheesy material imbedded in the

gland-parenchyma. In the further progress of the change the whole gland

is transformed into a homogeneous yellowish substance. In this

condition there are found on microscopic examination globular

corpuscles, nuclei, shrivelled cells, sometimes giant-cells, and most

frequently tubercles. The tubercles are usually found in the follicular

substance. Birch-Hirschfield says the cheesy formations in secondary

tuberculous mesenteric glands are only found in discrete foci, and the

tubercles occur in the follicular substance imbedded in relatively

normal tissue. The cheesy transformation is, according to Virchow, a

necrobiosis of the hyperplastic gland-elements, but Schüppel insists

that it is the result of tubercular development. After a time the

cheesy masses soften, and the glands are converted into sacs containing

a purulent fluid mixed with débris. In this condition they are most

frequently coalesced in bunches, sometimes forming large tumors. The

intervening walls may break down and the whole bunch be transformed

into one large sac filled with purulent fluid and débris. Occasionally

these masses of agglutinated glands become adherent to the abdominal

parietes or to the intestines. Rupture of their walls may occur, and

the contents may be emptied into either the peritoneal cavity or the

intestines. When communication with the intestines takes place, it is

usually through an ulcer on the mucous surface. It is probable that the

cheesy substance may sometimes be absorbed, as Virchow thinks, by

gradual softening proceeding from the surface toward the centre.

It is believed that these degenerated glands sometimes undergo the

cretaceous transformation. Such an instance has been reported by

Carswell: "The patient, who when a child had been affected with tabes

{1188} mesenterica and also with swellings of the cervical glands, some

of which ulcerated, died at the age of twenty-one years of inflammation

of the uterus seven days after delivery. Several of the mesenteric

glands contained a dry cheesy matter mixed with a chalky-looking

substance; others were composed of a cretaceous substance; and a tumor

as large as a hen's egg, included within the folds of the peritoneum,

and which appeared to be the remains of a large agglomerated mass of

glands, was filled with a substance resembling a mixture of putty and

dried mortar, moistened with a small quantity of serosity. In the neck,

and immediately behind an old cicatrix in the skin, there were two

glands containing, in several points of their substance, small masses

of hard cretaceous matter." Calcareous concretions have been observed

by Andral and others in the mesenteric glands in cases of chronic

pulmonary disease; and Soemmering records several observations of a

tartar-like substance found in devastated mesenteric glands in cases of

rickets.

The morbid appearances in tabes mesenterica are not usually confined to

the changes in the glands. In very many cases the evidences of disease

of the peripheral glands are quite manifest, and in much the larger

number of cases pulmonary phthisis and disease of the bronchial glands

are present. The adjacent abdominal organs may also be involved. These

consecutive morbid changes are succinctly set forth in the following

notes of an autopsy taken from the records of the Children's Hospital

of Washington, D.C. The subject was a negro boy aged ten, who had been

taken sick a year previous to his death with a bad cold and cough,

followed several months afterward by enlargement and suppuration of the

cervical glands on both sides: "The body was greatly emaciated, the

lips and teeth covered with sordes. Cheesy masses were scattered

throughout the substance of both lungs. The right lung was firmly

adherent to the thoracic walls, the left adherent at apex. The liver

was enlarged and adherent to all adjacent tissues, and contained many

cheesy nodules scattered throughout its substance and over the surface.

The gall-bladder was distended with bile. The spleen was normal in

size, very dark, and filled with cheesy masses. The pancreas contained

many similar masses. The peritoneal cavity contained a quantity of

muddy fluid. The peritoneum was dark in color, studded with tubercles,

and ulcerated in a few places. The stomach and intestines were

distended with gas; the walls of stomach thickened, the inner surface

covered with a shiny mucus; in its lower wall was one large ulcer,

penetrating to the peritoneal coat and measuring three-fourths of an

inch in diameter. The peritoneal coat was thickly studded with nodules

resembling tubercles. The small intestines were gangrenous in a few

places; on the inner surface were found fourteen ulcers, varying in

size from one-fourth to one and one-fourth inches in diameter, with

elevated edges and red bases; two penetrated the peritoneal coat. This

coat contained very many tubercles. On the mucous surface of the large

intestines there were seven large ulcers, similar in appearance to

those found in the small intestines. Some of Peyer's patches were

ulcerated. The mesenteric glands, some as large as walnuts, were filled

with cheesy material, and the mesentery was dotted over with small

masses of similar matter."

In two of the reported cases of chylous effusion into the peritoneal

cavity the rupture of the lacteals was caused by degeneration of the

{1189} mesenteric glands; and in several other cases the rupture was

produced by the presence of tumors, apparently formed by the

agglomeration of numerous degenerated glands.

Several cases of fatty diarrhoea from mesenteric phthisis have been

reported. Of these the most conclusive is the case of Hall.[1] The

clinical history of the case and the detection of enlarged mesenteric

glands in the umbilical and hypogastric regions placed the diagnosis

beyond a doubt. It was, however, verified by the discovery of several

vomicæ in the lungs, and of mesenteric glands "universally enlarged and

affected with strumous disease. The intestinal mucous membrane was

dotted with patches of ulceration, with here and there prominent masses

of strumous deposit on the surface."

371.]

SYMPTOMATOLOGY.--It is not possible to describe a definite and uniform

clinical history of this disease. As a secondary complication of

pulmonary phthisis and scrofulous affections the preliminary symptoms

are so constantly identified with the development and progress of these

maladies that, as a rule, the initial stage cannot be recognized by any

special assemblage of symptoms. In any tuberculous or scrofulous child

the possible implication of the mesenteric glands may be predicated

upon any array of symptoms that would establish the presence of these

classes of disease. And even in the absence of the rational and direct

signs of such affections, in those exhibiting the physical evidences of

the strumous diathesis, more especially when it is inherited, the

symptoms of any trivial departure from health, such as the catching of

cold, irritation of the alimentary tract, or protracted convalescence

from any of the exanthematous or intestinal diseases, may constitute

the initial history of tabes mesenterica. In such subjects debility and

anæmia, from whatsoever cause they may apparently result--and, in fact,

any manifest lowering of the standard of health, whether gradual or

precipitate, and without assignable cause--may mark the beginning of

the process of change in the parenchyma of the glands that will

terminate in tuberculosis. The later as well as the earlier history may

be completely masked by the symptomatology of other diseases belonging

to the tuberculous class; and so grave, as a rule, are such primary and

coexisting affections that definite recognition of this complication or

localized extension of the systemic infection becomes more a matter of

skilful diagnosis than of practical utility.

But in those cases where disease of the respiratory organs and of the

bronchial glands can be excluded the general symptomatology becomes of

paramount importance. And in view of the value of prophylactic measures

which may be employed to arrest, limit, or delay the localized

tuberculosis of these glands, the precursory symptoms may be of special

significance. This condition may be characterized by languor and

dulness or marked debility and anæmia, with loss of color, attended

with flatulence, stomachal disturbance, frequent eructations consisting

mainly of mucus, a sense of uneasiness in the abdomen after the

ingestion of food, a variable appetite, sometimes voracious and

occasionally depraved. Sometimes a dislike for fatty foods is a

prominent symptom. The tongue may be coated, the breath is usually

foul, and some have said the body emits an acid odor. If these symptoms

occur in a child of the {1190} scrofulous diathesis, or be directly or

remotely associated with a previous gastro-intestinal disease, or occur

or persist during the convalescence of some of the acute affections of

infancy and childhood which stand in etiological relation to this

disease, they may justify a reasonable presumption of commencing change

in the mesenteric glands. This presumption will be strengthened by

emaciation, a more marked disturbance of the digestive function,

attended with fetid and occasionally whitish stools, a tumid belly, and

deep, lancinating abdominal pains of short duration, recurring at long

intervals and neither relieved nor aggravated by pressure or an

evacuation. Some have attributed special importance to a chalky

appearance and loss of consistency of the stools, indicating the

suspension of absorption by the lacteals. There may also be slight

evening fever. Later, the enlargement of the belly increases, the

emaciation becomes more marked and rapid, the appetite more variable,

sometimes very voracious, the alvine discharges more fetid or less

consistent, sometimes putty-like, and generally irregular or

constipated. The febrile exacerbations are more decided, and sometimes

chills may occur at irregular intervals. When, in addition to these

symptoms, either during the earlier or later stages, the enlargement of

the glands can be detected, the clinical picture is complete. In

consequence of the tympanitic distension of the abdomen, which usually

increases with the progress of the disease, it is impossible in a

majority of cases to detect the glandular enlargement; especially is

this true when the affected glands are separate; but, as frequently

happens during the last stage, when large tumors are formed by the

coalescence of a number of diseased glands the diagnosis may be easily

determined. In the absence of the discovery of enlarged glands the

diagnosis cannot be considered positive. They are usually most readily

found in the region of the umbilicus, and may in some cases, even when

the tension of the abdomen is very great, be detected by grasping the

abdomen with the hand and compressing it between the fingers and thumb

so that the enlarged glands will be brought in close contiguity to the

walls and be felt immediately under the fingers. If a tumor should be

present and the peritoneal cavity be free from fluid, its locality may

be recognized by a sense of resistance and circumscribed area of

diminished resonance, and then definitely outlined by palpation.

Underwood says: "Indigestion, costiveness or purging, irregular

appetite, flushed cheeks or a total loss of color, impaired strength

and spirits, remitting fever, and a hard and tumid belly, with

emaciated limbs, are amongst the more common symptoms, attending at one

period or other, of this disease."

When the diagnosis has been made out, it is not impossible to determine

the stage of the disease. The progressive intensity of the symptoms,

with rapid emaciation as a rule, bears a definite relation to the

progress of the morbid changes taking place in the glands. It must,

however, be borne in mind that children have died of tabes mesenterica

who had enjoyed excellent health up to the moment of death, and the

autopsy disclosed the condition of the glands, which had not been

suspected during life. In the case previously cited, in which the

autopsy exhibited such grave lesions of the stomach, liver, spleen,

pancreas, and intestinal mucous membrane, the clinical phenomena were

at no time commensurate with the gravity of the morbid changes.

{1191} DIAGNOSIS.--In the absence of the proof of the presence of

enlarged glands or of a tumor the diagnosis cannot be positively

determined. The enlargement and tympanitic distension of the abdomen do

not necessarily establish the existence of glandular disease, for they

are present in a great many conditions of ill-health in children. Nor

is the coexistence of a tumid belly, emaciation, and fever sufficient,

for they are found in other tuberculous and in gastro-intestinal

diseases. The discovery of enlarged discrete glands by palpation, as

before described, in connection with such disturbances of nutrition as

have been set forth, constitute the strongest presumption in favor of

tabes mesenterica. The presence of enlarged glands unaccompanied by the

ordinary symptoms of the tuberculous or scrofulous processes is

inconclusive, because the glandular hypertrophy may be a simple

hyperplasia, entirely independent of any tendency to retrogressive

metamorphosis. There is usually some tenderness on pressure, but this

may be present in any disease of the abdominal viscera. When the glands

are of sufficient size, they may, by pressure, produce secondary

derangements. Cramps in the legs may be caused by pressure on nerves.

Oedema of the legs and dilatation of the superficial abdominal veins

may result from compression of venous trunks. "If," says Eustace Smith,

"these veins are seen to ramify on the abdominal surface and to join

the veins on the thoracic walls, tabes may be suspected in the absence

of chronic peritonitis and enlargement of the liver." Ascites may be

present, but is not a necessary result of disease of the glands.

When a tumor has been discovered by palpation, it is necessary to

determine its glandular nature. If situated about the umbilicus, in

front of the spinal column, if irregular, hard, and feeling like a

congeries of irregularly-rounded nodules, the evidence is very decided

in favor of its glandular origin. But care must be taken to exclude

tumors formed by fecal accumulations and masses attached to the

omentum. Omental tumors are usually more movable, better defined, more

superficial, and regular in form. Cancerous masses sometimes simulate

glandular tumors. The general history of the case and the age of the

patient are usually sufficient to make a diagnosis by exclusion.

Rilliet and Barthez distinguished a cancerous pancreas by the presence

of vomiting, jaundice, and abdominal pains.

The writer has many times based a conjectural diagnosis--which was

verified by a post-mortem examination--upon the presence of a tumid

abdomen, increasing emaciation, with the history of a protracted

gastro-intestinal catarrh, and an irregular febrile curve characterized

by frequent subnormal temperatures. He has also observed a number of

cases of protracted diarrhoea in children, accompanied with extreme

emaciation, notwithstanding the appetite was good, sometimes even

voracious, and the food taken was ample, nutritious, and easily

digested, in which the stools, varying from two to three, or twice as

many, daily, were whitish, leaden, or slate-colored, sometimes

semi-fluid, at other times containing lumps or masses of putty

consistence, presenting to the naked eye a greasy appearance and to the

touch a fatty feel, and at the autopsy has found only thinness and

transparency of the coat of the small intestines and degenerated

mesenteric glands.

PROGNOSIS.--The prognosis is decidedly unfavorable. So far as is known

to the writer, there is but one recorded case of recovery in which the

{1192} diagnosis was indisputable and the fact of a cure was

established by an autopsy. This was the case reported by Carswell,

before referred to. The older and some of the modern authors have

claimed many recoveries, but it must be manifest to every student of

pathological anatomy that the mistaken diagnoses must have been nearly

if not quite as numerous as the cases of cure. The writer has not

witnessed a single case of recovery, but he has observed very many

cured cases of disease which exhibited all the subjective and objective

symptoms of tuberculosis of the mesenteric glands, save and except

those by which its existence can alone be definitely and positively

established. The case of Carswell demonstrates a remote possibility of

cure by the cretaceous metamorphosis of the degenerated glands in a

subject exhibiting the scrofulous diathesis. In view of this isolated

observation, one cannot refuse to accept a similar possibility in cases

in which the disease may be localized and confined to a few of the

glands. In such cases, if recognized previous to the formation of

cheesy foci, the possibility of staying, limiting, and perhaps

occasionally curing, the disease should not be regarded as absolutely

hopeless; yet the opportunities of examining the glands in the first

stage of change has so rarely occurred that no one is authorized to

assert that the hyperplasia is the true picture of the condition in

which those in the advanced stage had its beginning; nor has any one

claimed to have witnessed the progressive stages of resolution taking

place in such glands.
