Chapter II: Part 2

Most frequently tubercular affections of the bones are found in the hip-joints, the knee and the spinal column.

_Tuberculous inflammation of the hip-joint_ is principally a disease occurring in childhood; though it rarely appears before the third year. It is most frequent from the fifth to the tenth year.

Inflammation of the hip-joint developes very slowly in children, it generally takes months before the slightest beginning symptoms reach a threatening appearance. The first sign is _lameness_; among laymen tuberculous inflammation of the hip-joints is known as "voluntary limping."

By limping we understand that mode of walking in which one leg is spared and by this the trunk is supported only a short time by one extremity and all the longer by the other. In every painful affection of the lower extremity limping results as the weight of the body increases the pain. The lameness in the case of diseased hip-joint has something peculiar about it, inasmuch as not only a part of the extremity but the whole of it is dragged. For this very reason parents of children afflicted with inflammation of the hip-joint use the expression "the child draws" or "drags the leg".

In the beginning even the examining physician finds no symptoms of disease in the joint. No swelling, no abnormal position, no restriction of the freedom of motion, no pain from pressure or while moving, in short nothing can be found that would otherwise indicate the beginning of an inflammation of the joints.

Yet _lameness only_ is sufficient data from which we may infer the probable beginning of hip-joint inflammation. It is much better to overestimate the significance of this symptom than to miss the proper time for calling in the aid of a physician by placing too little confidence on it.

The second symptom, _pain_, rarely attends the beginning of lameness, generally it comes several weeks later and in the case of very slow development of tubercularly inflamed hip-joint several months later. In very small children the attendance of pain is manifested by the fact that they will not play and they often wake up in the night and begin to cry.

Children from the fourth and fifth year upward definitely point out the hip as the seat of pain, sometimes, however, the knee-joint on the diseased side is designated with great determination. This pain in the knee has often been the cause of mistakes.

Later on painfulness of the hip-joint is experienced from pressure and at about the same time the movements are impeded.

Then the leg takes a peculiar position. The thigh is slightly bent and rolls outward. For convenience the child drops the half of the pelvis corresponding to the diseased hip-joint, and naturally raises the other half. From this apparently a curvature of the spinal column results in the lumbar region. Apparently only, for when the child is laid down and the morbid position of the thigh is restored the curvature of the lumbar column disappears.

During the further progress of the disease the pain is increased, and the sensibility may become so acute that the slightest movement of the limb, even a shaking of the bed in which the patient lies will cause the most intense pain. In the previous stage walking could only be done for short distances and then awkwardly, now it is entirely impossible. Children are obliged to lie in bed night and day, and under these altered conditions there is a change of the position of the extremity. The increased sensibility induces the child to seek the medium position, the leg is bent more than in the position mentioned above, it is halfway straightened.

To this is added, that the child can not lie well on the sensitive and swollen hip; with right side hip-joint inflammation it turns on the left. As the diseased and bent thigh does not then rest on the mattress the same is placed on the healthy limb for support and for protection from movements, in the same manner as we lay one leg on the other in a healthy condition when we sleep on our side.

The actual danger to life in tuberculous hip-joint inflammation begins with the time when the child takes to his bed. The fatal end comes almost without exception after suppuration has commenced, very rarely before that time. Total suppuration of the hip-joint is an almost absolutely fatal process. If this suppuration sets in suddenly, it may result in an early death with attendance of acute fever. In other cases several weeks may elapse from beginning suppuration till death.

A complete cure of tuberculous hip-joint inflammation may come about spontaneously. But often the knee remains bent and unserviceable for walking, so that crutches or machines must be used.

Even before this the beginning stages were treated with fair prospects of success, and it is a lamentable fact that in many cases the import of these seemingly trivial symptoms has been underestimated.

_Rest_ is of the greatest importance during the very first stages of the disease in which the attending symptoms are of so indefinite a character that it is almost impossible to know whether hip-joint inflammation will develop or not; the child must not be allowed to walk. Aside from this the application of brine-, malt- and sea-water baths is advised. An abundance of nourishing food is of just as great importance. All this will also retain its significance in the future.

Formerly recourse to surgery has been taken during the later stages of the disease in which suppuration of the internal parts of the joint has commenced and large parts of the diseased bones may have become mortified. An incision is made into the joint, the same is exposed and all diseased portions are carefully removed. In the future this operation must probably also be performed, although with the difference that the prospects of success are now much more certain than formerly when relapses only too often followed the operation.

_Tuberculous inflammation of the knee-joint_ is, as said before, very frequent with children and is rather lingering in the beginning. Here also a slight dragging or limping of the diseased leg can be noticed. The child when asked about the limping, or of its own accord, complains of pain in the joint after walking or when the part is pressed; at first nothing abnormal can be seen on the knee by the layman.

On closer examination, however, by comparing the two knees it will be found that the grooves on each side of the patella, which give the healthy knee-joint the beautifully modeled shape, have nearly or quite disappeared; nothing more can be noticed.

The hinderance in motion may be so insignificant, that the children may slightly limp about for weeks and months and complain but little. Generally the physician is not called until the limb begins to hurt and swell after continued exertion.

The swelling which in the beginning is hardly noticeable is now more plainly visible, the knee-joint is evenly rounded and quite sensitive to pressure.

If the disease is not now properly treated, its further course will be as follows: the patient may perhaps linger for several months; then comes a period when he must keep to his bed uninterruptedly because moving results in too much pain; generally the limb becomes more and more bent.

Now particularly painful points appear on the joint, especially on the inner or outer side or in the bend of the knee; on one of these points a soft portion distinctly developes, the skin becomes reddened and finally suppurates from the internal parts outward and breaks after a few months; thin purulent matter mixed with flakes is discharged. The pains now cease, and the condition is improved; but this improvement does not last; soon another abscess is formed and thus it continues.

Meanwhile perhaps two or three years may have elapsed; the general condition becomes greatly reduced. The child, formerly strong and healthy, has now become lean, the discharges of matter have often been attended by acute febrile attacks; the patient becomes exhausted, loses his appetite and digestion becomes more impaired from week to week. Even now a spontaneous change for the better is possible, though this happens very rarely; more frequently the disease progresses and leads to death from exhaustion resulting from severe suppuration and continual attacks of fever.

Restoration to health is indicated by decreased suppurative discharges; the openings of the fistulae contract, the general condition is improved, the appetite is restored, etc. Finally the fistulae heal, the joint becomes fixed at an angle or bent or otherwise crippled, but painfulness disappears and the patient escapes with his life and a stiff leg. This is the most favorable result known to have been obtained in severe cases. The joint may become a solid bony immovable mass or may admit of slight movements. The whole process may last from two to four years.

The former treatment of tuberculous inflammation of the knee-joint was either of a general or a local nature. The general treatment was designed to strengthen and nourish, and will continue to be applied in the future.

The local treatment consisted in the application of salves, brushing with tincture of iodine, spanish fly plasters, wet and dry bandages. As with inflamed hip-joint absolute rest by lying in bed is of the greatest importance.

If after a certain period of rest and application of the above-named remedies no improvement in the state of health could be noticed, the diseased joint was laid in plaster or confined with splints.

If even then, after such treatment for months, no improvement could be noticed but rather that the general state of health was reduced, nothing remained to be done excepting an operation, by which all the diseased parts of the knee-joint were removed, or amputation, that is, the taking off of the diseased limb. The latter method was generally adopted in the case of feeble and emaciated individuals and those who had passed the age of early manhood, as with these the removal of the diseased parts did not, as a rule, result in an improvement of the general condition, which was especially intended.

Now tuberculous inflammation of the knee-joint will be treated by Koch's method and in extreme cases only will operation be necessary. At all rates, an absolute cure will be easily effected.

Aside from the hip- and knee-joint the _spinal column_ is most frequently attacked by tuberculosis. Here also it is the youthful age, from the third year upward, that has to suffer most from this serious disease. Adults are rarely attacked by it and with them it generally appears in connection with general tuberculosis.

The tubercle-bacilli penetrate into the substance of the vertebrae, destroy the same and transform it into purulent matter. As a result the destroyed vertebrae sink or rather settle down and cause a curvature of the spine, in other words a humpback.

In the beginning the symptoms of diseased spine are very indefinite and misleading. The patient rarely complains of pain at first, and it is only noticed that the sick child easily tires of standing or walking and tends to hold on to chairs and similar objects with his hands to relieve the spinal column of the weight. From such uncertain data it is of course impossible to recognize the disease.

Only then when the softened vertebrae give way under the weight of the body, that is when the humpback begins to develop, can tuberculous inflammation of the spine be surmised with any degree of certainty.

As a rule two other characteristic phenomena appear which are dependent on the pain in the affected spinal column. The child, while standing, places his hand on the thighs and thus directly supports part of the weight of the trunk with the lower extremities; at the same time he avoids bending the spinal column forward. This anxious care for the diseased vertebrae is especially noticeable when the child attempts to pick up an object from the floor. While the healthy child bends freely forward, the sick one crouches down and while bending the knee and hip keeps the spinal column as straight and stiff as possible. Frequently a small spot on the spinal column is found to be extremely sensitive to pressure in this stage; but such a subjective symptom must be considered with caution especially with children.

This humpback, which is a result of tuberculous inflammation of the spine, must not be confounded with the humpback caused by rickets. With the latter the curvature is more uniform as a rule, and in the start at least, disappears while in a horizontal position. Besides the humpback resulting from rickets appears between the first and fourth years of age, while tuberculous inflammation of the spine rarely begins before the fourth year. And finally rickets never causes suppuration while this is always the case with inflammation of the spine.

The progress of suppuration is downward as a rule and does not admit of examination until it gets near to the surface of the body; before this the feverish conditions toward evening are the only signs that indicate beginning suppuration. Ardent fever is not attendant during this time; the temperature does not exceed 38 or 38.6 deg. C. and even such trifling increase of temperature may be wanting.

As soon as the skin is reached by the originally deepseated centres of suppuration, it gradually becomes red and later on also suppurated. If the skin is broken and the matter discharged, great care must be taken to keep the wound clean, as otherwise the suppurative cavities may suddenly become ichorous and lead to rapid death. In other cases this extreme result is not caused and fistulae are formed from which the ichor constantly flows. Small bits of mortified and broken off bones may be thrown out with the matter.

As a result of the sinking and settling of the vertebrae the spinal chord may suffer from pressure and contusion as it is contained in a channel formed by the vertebrae. Aside from certain pain it may result in paralysis of certain parts.

Formerly the diagnosis of tuberculous inflammation of the spine in its beginning stages was very uncertain. A great number of afflicted are at present cured by surgical treatment; in former times this was not possible, as the majority of patients died in whose case the disease had progressed to suppuration. But the curvature of the spine could not be removed by any former treatment and can not be by Koch's new method. Vertebrae once destroyed can in no way be restored to their normal condition.

Nevertheless the number of patients whose life is spared will be a still greater one and the number of complete cures will also be increased in a short time. Formerly tuberculous inflammation of the spine was treated as follows: the abscesses were opened and antiseptics carefully applied: mechanical apparatus and corsets were used to aid in a natural cure. These apparatus will surely be of inestimable value at the application of Koch's method.

As has been stated before tuberculosis may attack all other bones and joints and there cause the most serious derangement. Formerly these tuberculous afflictions were treated surgically or by means of iodoform, which has produced pretty good results in certain cases.

However it will certainly be possible to produce still better results with Koch's method of treatment, especially in the restoration of the functions of the afflicted parts. Here, as in all tuberculous affections, it is particularly essential to subject the respective case to treatment in as early a stage as possible and before incurable destruction of the tissues of the bones and joints have been caused.

A certain disease of the skin called _lupus_ (ringworm) must be counted in with the number of diseases generated by the tubercle-bacillus.

Lupus may begin in two different ways. Either in the form of a purple spot, which is raised above the level of the skin and which has no definite limits but blends with the healthy parts; or as a slightly raised, moderately firm, darkred grain, sharply limited and about the size of a pinhead or millet seed.

If the disease has begun in the shape of spots, the afflicted portions of the skin gradually swell during the process of the disease. Several isolated knots appear around which the disease spreads more and more.

While the disease thus takes possession of greater area and developes new centers, a uniform scaling off of all knots begins.

After prolonged existence, sometimes after short duration, decay and casting off of the epidermis in its entire thickness supercedes the scaling process, and suppuration transforms the ringworm into an ulcer covered by a dirty-brown rind and disagreeably colored serum.

The ulcers of lupus are of various, generally irregular shape, the rims not hard, the ground flat and covered with purulent matter and decayed tissue; they are commonly surrounded by a faint reddish areola. These ulcers gradually become epulotic and form irregular, generally slightly protruding white scars in which new tubercles may appear.

Lupus appears most frequently in the face and especially frequent on the nose. Sometimes its appearance is indicated only by an inflammation and swelling of the mucous membranes of the nose and at the same time a reddening of the epidermis. The nostrils are stopped up by a thin rind which, if torn off, is replaced by a thicker one below which an ulcer is formed that spreads with greater rapidity on the mucous membranes of the nose than on the external epidermis of the same.

Sometimes the whole process on the nose is so rapid, that very often the physician is not called to the patient, before a large part of the wing of the nose or of the nasal epidermis is destroyed and deep ulcers have developed under the rind. New tubercles of lupus are commonly noticed to spring up on the margins of these ulcers; the cartilage as a rule resists the progress of the disease for a longer period and may be unhurt, while the skin on the wing of the nose may be completely destroyed.

Frequently the process is extended to the mucous lining of the hard palate and to the gums. Lupus generally appears on the lips in the same manner as in the nose. The upper lip especially appears very much swollen and covered with ulcers after a prolonged existence of the affection. Sometimes even the aperture of the mouth itself is reduced in size by the development of ulcers and scars on the surrounding parts.

If the process extends to the lower eyelid, the connective tissue as a rule becomes much swollen and reddened. The malady especially attacks the inner angle of the eye, destroys the entrance of the lachrymal duct, and from there the lupous tubercles appear on the connective tissue. Gradually tubercular formations develop on the cornea and sight becomes impaired.

On other parts of the face lupus generally appears in the form of small knots, about the size of millet seeds, which remain for a time then multiply and spread. The epidermis swells between these knots and irregular ulcers develop on a hard swollen and glossy ground, and are covered by dark brown rinds.

Tubercles appear anew on the margins of the ulcers and in the spaces between them, isolated whitish spots of sunken or raised scab tissue are observed on which very frequently lupous tubercles again develop.

Lupus appears on the throat, neck, back, breast, and the extremities, most frequently in serpentine form i. e. swellings of the skin develop, being arranged in curves, they progress in the same manner, these are transformed into just so many ulcers. Between these whitish scarred spots are noticeable on which small red lupous tubercles again appear.

Lupus is more frequently found on the extremities than on the trunk. The surface of the skin is found to be tense and glossy on a firm base which is affected by lupus.

Deep ulcerous formations of lupus are sometimes observed on the fingers and toes, particularly on the finger-joints, these may at times penetrate into the inner parts of the joints, secreting whitish pus and covered with a thick rind.

As regards the difference between lupus and syphilitic diseases it has been found that lupus commonly developes before puberty while syphilis appears in the mature age.

The ulcers of lupus are often round like those of syphilis with sharply defined margins, but at the same time they are flat accompanied by little or no pain; rim and base of the same are loose, red, rank, and bleed easily. On the other hand syphilitic ulcers are very painful and rim and base are covered with greasy matter.

Lupus appears only in the form of knots, which are deeply inbedded, from size of a pinhead to that of a lentil, but never as large knots in the beginning. Syphilis produces large and palpable knots from the start.

Loss of the bony part of the nose or destruction of the hard palate are observed, but rarely and after protracted existence of lupus, and often in the case of syphilis.

The indicated peculiarities however refer only to typical cases of lupus and of syphilis. In other cases it was almost impossible to show a difference.

As regards the course of lupus, the same begins, as has been stated before, in earliest childhood, sometimes only in the form of scaly spots and knots. Less often lupus developes after complete development of manhood. It is more frequent with women than with men. Sometimes some of the knots remain isolated and disappear again after a time; in other cases additions appear in the course of time, which may affect larger portions of the body and lead to more or less dangerous ulcers. As a rule the course of lupus, even of great extent, is not malignant and at the most the alliance with _traumatic erysipelas_ and possibly the appearance of _pulmonary consumption_ may succeed the affliction. In cases of not too rare occurrence it has been observed that lupus has developed into _cancer_, which has always resulted fatally.

The _treatment_ of lupus has principally been a _local_ one. Caustics were applied to destroy lupous tubercles by direct action, and furthermore recourse has been taken to the so-called mechanical treatment, in which the ringworm was scraped out.

Our experiences relating to the mechanical treatment of lupus have taught us the following.

Lupus can not be cured without destroying and removing the diseased and affected tissue. That method which effects the most radical destruction, protects most from relapses. Therefore the best method of treating lupus is to cut out the diseased skin. But with the superficial spreading peculiar to many cases of lupus this method can only be applied within certain limits. Then again the secondary growths after an operation may be of serious consequences.

Unfortunately it has not been possible before this to remove all diseased portions, no matter what method was applied, because often tiny lupous tubercles spring up which are almost invisible to the naked eye. These tubercles will again be the starting point for another spreading of lupus.

We will see that Koch's new method to cure has the advantage both to make visible all tubercles, even those that have escaped our notice and also to effect a cure in the shortest time even in old chronic cases that have before this been considered incurable. It is especially possible in this form of tuberculosis to follow the specific action of the new remedy, as we will learn later on.

_Tuberculosis of the testicles_ is not so very rare, it is found in about 2-1/2 per cent. of all men afflicted with pulmonary consumption. It is more rarely met with in children than in men.

The conditions under which tuberculosis of the testicles and epididymis developes are various inflammatory processes with existing disposition. It is mostly gonorrhea or some other inflammation of the urethra, or injured testicle. It occurs less frequently without any apparent cause.

According to the starting point of tuberculosis the symptoms are varied. If it starts in the testicle, this appears normal or larger in size, but never reaches extraordinary dimensions. The surface of the testicle is at first smooth in the case of increased tension, later only does it become irregular, bumpy and of unequal consistency.

If the starting point is in the epididymis, hard, rounded lumps are formed generally in the head or tail of the epididymis, rarely in the body. These increase in size and cause a swelling often of extraordinary dimensions, the surface of which appears hard, irregular, bumpy and in certain parts yielding and elastic. If the process is extended to the testicle, this also increases in size. Then both together form an oval swollen mass and can not be distinguished from each other.

Striking changes appear only later and consist in the softening of the lumps and in the development of abscesses.

Very soon the lobuli are affected. The same are then thickened in the septa, are hard and form an irregular, bumpy swelling surrounded by more or less thickened tissue.

Very soon tuberculous changes are caused in the prostate gland, an organ situated near the intestine and the functions of which are to dilute the semen. A hardening is often the first sign, this is followed by increase in size and then softening.

With the affection of the prostate gland, that of the urethra also begins, which passes through the middle of the prostate gland. This disease often appears in the form of a yellowish secretion, which is more and more increased and becomes ichorous with the decay of the urethra and the prostate gland. This secretion must be distinguished from that which as a venereal affection caused the whole process. The tubercular derangements do not only extend forward but also upward. The bladder, the ureters and the kidneys are affected and show extreme derangements with altered urinal secretions and excretions.

Of other symptoms of tuberculosis of the testicles pain deserves especial mention. The same is slight in the beginning, but often becomes insufferable.

The symptoms here related often increase very slowly. Essential changes are caused during the chronic course of tuberculosis of the testicles if suppuration sets in. The skin is perforated and fistulae are formed. If there is no halt in the process, general tuberculosis results and this has until now always caused death.

According to the time in which the general derangements come about, a chronic and acute tuberculosis of the testicles has been distinguished. The former is the more frequent, the latter of rare occurrence.

The sexual functions may remain unchanged if only one testicle is diseased, but are generally ruined if both epididymes are affected, because the secretion of the semen is then interrupted by the stopping up of the vas deferens. In some cases the sexual function may be interrupted for a time only and may then be resumed.

The treatment before this has been surgical, in which the diseased parts were carefully removed, and where this was impossible, even castration (removal of the testicle) was performed. Without doubt Koch's method will cause great changes in the method of treatment here also.

Finally we must include in our reflection the well-known disease of children, _scrofula_. Although the same is not a form of tuberculosis in the sense of the diseases just considered, still tuberculosis and scrofula have the most intimate relations. Scrofula is only too often a precursory stage of tuberculosis.

The manifold scrofulous affections, such as inflamed eyes, diseased ears, skin diseases, catarrh of the nose, pharynx or bronchials, inflammation of the joints and suppuration are not caused through the cooperation of tubercle-bacilli. But here the same find an excellent soil for growth and propagation, and they use the same to the full extent and so give the impetus for the development of tuberculosis.

Scrofula is one of the most frequent diseases, it is spread over the whole world. It occurs more seldom in the tropics than in the north. Furthermore it is more frequent in a cold and damp climate than in a dry one. Elevation has no influence on the development of this disease. Scrofulous individuals are found in the mountains as well as in the plains.

Scrofula principally attacks children; it occurs most frequently in the time from the second to the fifteenth year. Rarely earlier developed scrofula drags beyond the age of puberty or more advanced manhood. Sex has no particular influence on the development of scrofula.

In many cases this particular disease is _inherited_. The following causes are considered in the inheritance of scrofula: great age, close relationship and infirmity of the parents; but the germ of scrofula is planted in the child by parents that are themselves afflicted with tuberculosis or scrofula. This is most frequently observed in children that have descended from parents, who were scrofulous in their youth and remained so, or that became tuberculous later on and at the time of generation were afflicted by advanced scrofula or tuberculosis, or that were suffering from oft-treated but never entirely cured syphilis. Some scientists claim to have observed the inheritance of scrofula by children, whose parents at the time of generation were afflicted with tuberculosis or were suffering from general debility resulting from hunger and want.

In the majority of cases scrofula is acquired, as a rule the development of this disease is favored by indigence and poor hygienic conditions according to the coinciding experience of all scientists; _nutrition_, especially in the first year of life, has the greatest influence on the origin of scrofula.

In _infancy_ the most frequent cause of scrofula is the premature giving of _farinaceous_ food besides the mother's milk, or the feeding of children with so-called pap, especially when this is done in the _first month of their life_.

In later months the excessive eating of bread, potatoes or vegetables instead of milk has an injurious effect.

Furthermore the development of scrofula is favored by the breathing of _foul damp air_ such as is frequently found in newly built or damp houses and also by _deficient care of the skin_.

Scrofula thrives in the narrow tenement dwellings in which is found a close, overheated, foul air pregnant with smoke, kitchen fumes and mustiness from the damp walls.

Frequently the development of scrofula has been observed to succeed measles, diphtheria, scarlatina or whooping-cough.

The opponents of vaccination also designate vaccination as a frequent cause of scrofula. It is supposed that a poison is transferred into the system with the lymph which is enabled to generate the phenomena of scrofula. However the supposition has not as yet been proven.

Of course the fact cannot be denied, that cases of developing scrofula have been at times observed as succeeding vaccination. But the circumstances are the same as in the case of the contagious diseases mentioned above. No one will probably maintain that in those cases in which the development of scrofula had been succeeding those diseases, that this has resulted from a poison generated by the preceding disease.

The attempt to designate symptoms by which to recognize a scrofulous constitution has at all times been made. Many physicians have for a long time distinguished a _torpid_ and an _erethistic_ scrofulous constitution.

With a _torpid_ constitution the body is pale, spongy and bloated, the nose and lips are thick, the abdomen swelled, there is plenty of fat and but weak muscles. Such children are indolent, at times peevish and indifferent, they do not sleep quietly, have no appetite or may be voracious and suffer from derangements of digestion. An examination of all organs indicates no change. The children are easily afflicted with eruptions of the skin, with inflammation of the eyes and ears, and catarrh of the mucous membranes, which are characterized by great obstinacy. The derangements in nutrition here described are caused by the lymphatic glands though a swelling of the same can not be found.

In the case of _erethistic_ scrofula the children are found to be of slight and lean structure, with fine hair and long eyelashes; they are active, easily excited, gifted and extremely sensitive to physical pain. The face is pale and becomes easily flushed by physical or emotional excitements. They are easily subject to palpitation and short breath; and are attacked by high fevers from the slightest reason. The lymphatic glands, especially the deepseated ones, are as a rule more or less swelled.

In most cases, however, the characteristics of these two forms are blended.

The phenomena of scrofula are manifold and extend over the entire body.

The _skin_ is frequently the seat of scrofulous affections. These are particularly found on the head and face and are characterized by great obstinacy and tendency to return.

Most frequently herpes appear, the parts especially affected are the scalp, face, auricular passages, eyelids and the nose with its surrounding parts.

Pustules are sometimes developed under the skin and may appear in great numbers. These pustules may either break through the skin or shrink into a caseous mass.

Of all _mucous membranes_ that of the _nose_ becomes most frequently diseased; in a great number of cases this happens in the form of a chronic catarrh; the mucous membrane of the nose is reddened and swollen and a profuse, thick, purulent, ichorous and easily drying fluid is secreted. Often the external parts of the nose are swollen as a result of the catarrh and the nostrils are stopped up with thick yellowish-green rinds. Inflammation of the skin is caused by the flowing out of the purulent and ichorous liquid secreted.

In many other cases the disease appears in the form of scrofulous ulcers on the mucous membranes of the nose; in such cases it is found that the nose is stopped up with numerous yellowish brown crusts; after removing the same the mucous membrane appears swollen and moderately reddened, on several places ulcers, the size of lentils, are found which are covered with a yellowish gray coating. At the slightest touch bleeding of the nose is caused; often also the external parts are reddened and swollen. In such cases erysipelas frequently developes, starting from the nose and spreading over the whole face. Frequently a repetition of erysipelas occurs.

The scrofulous catarrh just described is generally of a very protracted nature and is marked by many relapses. Sometimes the fluid secretion of the nose is of very bad odor.

The mucous membrane of the _throat_ becomes diseased at the same time as that of the nose. The same is found to be moderately reddened and swollen; the lymphatic glands especially those on the posterior wall of the throat are increased to swellings the size as large as peas. The _tonsils_ also become inflamed frequently and become enlarged through the repeated rather chronic inflammation.

_Inflammations of the ear_ are a common occurrence with scrofula. These originate most frequently by means of the eustachian tube, which connects the ear with the back part of the mouth as a result of the catarrh of the nose and throat. In a majority of cases the inflammations of the ears lead to perforation of the tympanum and may even result in fatal cerebral meningitis.

The _eye_ is as frequently affected by scrofula. Swelling of the lids and inflammation of the glands are the lighter forms. Pustules on the connective tissue of the eye and on the cornea, accompanied by photophobia, cramp in the lids and flowing of tears are those severe forms that are so frequently observed in scrofula, and that often leave opaque and incurable spots on the cornea of the eye.

Swelling of the _glands_ has at all times been a characteristic phenomenon of scrofula. A swelling is merely the result of diseases of the mucous membrane of the throat or nose, of herpes of the scalp or face, of inflammations of the ears, eyes, periosteum, bones, etc. In the beginning the swelling of the glands is painless and results in flat swellings of about the size of filberts, which may be moved back and forth; such glandular swellings may exist for years, without showing the slightest alterations.

With renewed attacks they enlarge and may become of considerable size. At times single glands become inflamed, hurt when pressed and develop abscesses which perforate the skin after it has become inflamed and reddened.

These abscesses may heal within a few days. In the majority of cases, however, they remain for a longer period, months and even years and result in the well-known tumid, hard and immovable scars.

Inflammation of the periosteum and of the bones is one of the instances of scrofula. Most frequently _spina ventosa_ is found; the same consists of a gradual, painless swelling of the diseased bones, most frequently on the fingers and toes, so that they become bottle-shaped. The skin covering these swellings is pale and tense. The swelling may gradually disappear or begin to suppurate. Besides this hip- and knee-joint inflammation are observed, also inflammations of the ankle, elbow-joint, spine, etc.; especially in the case of diseased bones it is extremely difficult to fix a dividing line between scrofula and tuberculosis.

The frequence of anaemia with scrofula is only a _result_ of the disease and not a symptom. As a result of scrofula nutrition and assimilation become impaired, mostly in the cases of extreme suppuration.

Scrofula is a chronic disease. In many cases it is completely cured, the lighter cases after several months and the more malignant after several years. Extreme scrofula may often remain until puberty and may be completely healed.

_Fatal_ results are due to scrofulously diseased bones, joints or glands, and it can not be denied that a large number of children succumb in this manner. Fatal results may also be due to additional diseases, such as pneumonia, pleurisy, intestinal catarrh, etc.

It has been frequently observed that _tuberculosis_ succeeds scrofula. It is a well-known fact that scrofula furnishes the largest contingent for tuberculosis.

As a precautionary measure against scrofula a careful regulation of the diet is recommended. During the first nine months of life children should be fed with human milk exclusively if possible. If scrofula is hereditary in a family, or if the mother exhibits symptoms of the disease, she should not be allowed to nurse the child but a strong and healthy nurse should be engaged. Recourse to artificial nourishment must only then be taken, when nursing the child is absolutely impossible. For this purpose exceptionally pure cow's-milk ought to be selected. All substitutes, that appear under various names, such as infant's food, condensed milk, etc., contribute much toward the development of scrofula.

Children 1-2 years of age are to be fed with milk, meat and eggs. Only strong children, that show no sign of scrofula may be fed once or twice a day with small quantities of rice, tapioca, sago, green vegetables, pulse, etc., beside the food above mentioned.

To prevent scrofula it is essential not to give the food of adults to children during the first years of life; avoid exclusively solid food and prepare the same in a pappy form as much as possible. Of course a proper regulation of meal-time and a careful avoidance of overfeeding is by all means to be observed.

It is of no less importance for a successful treatment of scrofula to provide surroundings of as favorable conditions as possible.

First of all _pure air_ containing plenty of _oxygen_. Therefore the _sea-coast_ is recommended as a proper place for scrofulous children. The children ought to stay there until the signs of scrofula have disappeared and the entire nutrition has been improved. The results obtained in the sanitary stations (vacation colonies) along the sea-shore for scrofulous children have received much favorable comment.

_Mountain air_ has a similarly favorable effect especially when _salt water baths_ are used at the same time; even the plain, pure _country air_ proves beneficial to scrofulous children. _Very dry_ locations and dwellings ought to be selected. The children should remain _out of doors_ as much as possible.

Of great importance for scrofulous children, furthermore, is a suitable course in _gymnastics and rubbing-down with cold water_. To begin with the water may be 72 deg. but should gradually be reduced to the natural temperature of well water.

Just how far Koch's new method will take the place of former remedies used for scrofula can not be told at present as experiments in this direction are wanting. Nevertheless it will be possible to prevent the dangerous transition of scrofula into tuberculosis and thus save the lives of a great many persons.

Anyone who has informed himself through the foregoing as to the great number of diseases and forms of disease that are directly or indirectly connected with tuberculosis, will now be able to estimate the farreaching import of Koch's discovery. It will now be clear to him that pulmonary consumption constitutes only a part, although a great part of tuberculosis and that there are a great many diseases besides that can now be surely cured, it is hoped, with the aid of Koch's method. But this much should be remembered by everyone that this remedy also acts best and surest during the _beginning_ of a disease. We hope that no one will allow valuable time to slip unimproved; it may easily happen that it is too late for successful treatment. Everyone will be able to recognize the symptoms of diseases, which Koch has taught to cure, from the foregoing complete description, and it is better to apply the remedy once too often than miss the proper time for application.

Koch's first communications relating to the subject have just been published and will be given unabridged in the following pages. As these communications are written for physicians we will add such explanatory notes as are deemed essential for general intelligence.

THE FIRST COMMUNICATION

_Relating to a Method to Cure_

TUBERCULOSIS,

BY

Prof. R. KOCH, Berlin.

In a lecture, delivered by me several months ago, at the International Medical Congress, I referred to a remedy, which makes animal subjects impervious to the inoculation of Tubercle-bacilli, and in the case of diseased animals, checks the progress of the tuberculous disease. In the meantime experiments have been made with human subjects, about which I will report in the following.

Originally I intended to complete my investigations and especially gain sufficient experience concerning the practical application of the remedy and its production on a larger scale before I published anything concerning it. In spite of all precautions too much has already been published about it, and that distorted and exaggerated, so that I was obliged, in a way, to prevent false conceptions, to give even now a synopsis of the method as far as it has progressed at the time being. Under present circumstances it must necessarily be short and leave unanswered many important questions.

The experiments have been, and are still being made under my direction by Dr. A. Libbertz and Stabsarzt Dr. E. Pfuhl. The necessary subjects and material have been provided by Prof. Brieger from his Polyclinic, Dr. W. Levy in his Private Surgical Clinic, Geheimrath Fraentzel and Oberstabsarzt R. Koehler in the Charite-Hospital, and Geheimrath Herr v. Bergmann in the Surgical University Clinic. To all these gentlemen and their assistants I here tender my heartfelt thanks for their untiring interest which they manifested for this subject and also for the disinterested help and aid which they have offered at all times and without which it would have been impossible for me to make such progress in a few months in this difficult and responsible investigation.

As my work is far from being completed, I can not as yet make any statements relating to the origin and preparation of this remedy and reserve these for some future time.[1]

The curative is composed of a clear brown fluid, which in itself is not perishable, even without special precautionary measures. For use this fluid must be more or less diluted and these dilutions are perishable when made with distilled water; Bacterian vegetation soon develops in them and they become turbid and are no longer fit for use. To prevent this the dilutions must be sterilized through heat and be kept under cotton batting or be prepared with a 5 per cent. phenol solution which is much simpler. Through repeated heating as also through the mixture with the phenol the efficiency of the diluted solution appears to be curtailed after a time and for that reason I have always used solutions as fresh as possible.

The remedy does not act through the stomach; to effect a reliable action it must be applied subcutaneously. For our experiments we have exclusively used a syringe decided upon by myself for bacteriological purposes, which is supplied with a small india-rubber ball and which has no stamp. Such a syringe can be easily kept positively aseptic by rinsing with absolutely pure alcohol and on this we base the fact that not a single abscess has sprung from over a thousand injections.

After trying various parts of the body as places for application we selected the skin of the back between the shoulderblades and in the lumbar region, because at these places the injection was almost painless and caused the least and in most cases no local reaction.

Even at the beginning of our experiments we found that in one particularly important point the human subject was affected by the curative in a way decidedly differing from that of the animal subject generally used, the guinea pig. Therefore another confirmation of the rule for experimentors upon which hardly enough stress can be laid, not to rely upon a like effect upon the human being from the experiments on the animal without further confirmatory inquiry.

Man proved himself much more sensitive to the effects of the remedy than the guinea pig. Up to two cubic centimeters and even more of the undiluted fluid could be injected under the skin of a healthy guinea pig without causing any particularly disparaging effect. In the case of a fullgrown man on the other hand, 25 ccm. are sufficient to produce intense results. In proportion to weight of body therefore 1/1500 of the amount which has no noticeable effect on the guinea pig has a decidedly strong effect on the man.

From an injection that I have made on my upper arm I have experienced the symptoms which arise in man after an injection of 25 ccm., in short they were the following: Three or four hours after the injection a raking pain in the joints, languor, inclination to cough, oppressed breathing, which rapidly increased; in the fifth hour I experienced intense chills which lasted nearly an hour, at the same time nausea, vomiting, increase of the temperature of the body to 39.6 deg. C. After about 12 hours all these affectations ceased. The temperature sank and reached the normal height the next day. Heaviness of the limbs and languor lasted for a few more days, and for the same length of time the place of injection remained red and painful.

The lower limit of effect of the curative for a healthy man is about .01 ccm. (= 1 cubic centimeter diluted with a 100 parts) as numerous trials have shown. The majority reacted on this dose with only light pain in the joints and passing languor. With a few a slight rise in temperature set in, to 38 deg. C. or a trifle higher.

Although there is a marked difference as regards the dose of the curative (according to relative weight of body) between the animal subject and man, an evident resemblance is shown in several other qualities.

The most important of these qualities is _the specific action of this remedy on tuberculous processes of whatever kind they may be_. I will not relate the effects on the animal subject in this connection, as it would lead too far, but will at once turn to the peculiar effects on tuberculous human beings.

As we have seen, a healthy man reacts but little or not at all on .01 ccm. The same is true of diseased persons, provided they are not tuberculous. But the relations are entirely different with those afflicted with tuberculosis; a marked general and also a local reaction resulted from an injection of the same dose of the remedy (.01 ccm.)[2].

The general reaction consists of an attack of fever, which, beginning mostly with chills, raises the temperature to over 39 deg., often up to 40 deg. and even 41 deg. Other noticeable symptoms are pains in the joints, a tendency to cough, great languor, and often nausea and vomiting. Several times we observed a faint icteric coloring and in some cases the appearance on neck and breast of an exanthema resembling measles. As a rule the attack begins 4-5 hours after the injection and lasts 12-15 hours. In exceptional cases it may begin much later, but then it is not nearly so intense. The patients experience remarkably little weakness from the attack and feel relatively well as soon as it is over, generally better than they did before it came on.

The local reaction can best be observed on those patients whose tuberculose affection is plainly visible, for instance those afflicted with lupus. In them changes take place that prove the specific antitubercular action of the remedy in a most surprising way. The diseased portions of the skin in the face, etc. begin to swell and turn red even before the attack of chills set in, although the injection is made under the skin of the back, a point decidedly remote from the affected parts. The swelling and reddening increases during the fever and can attain a very marked degree so that the lupus-tissue turns reddish brown and necrotic. In the case of more sharply defined lupus centres the more swollen and dark red parts were edged by a white seam nearly a centimeter wide and this again was surrounded by a wide bright red border. The swelling of the diseased parts gradually decreases after the cession of fever and may have entirely disappeared after 2 or 3 days. A serum exudes from these lupus-centres and, drying, forms a crust on them which changes into scabs that fall off in 2-3 weeks and sometimes leave a smooth red scar after a single injection. Generally several injections are necessary to effect a complete removal of the lupose tissue, but of this I will speak further on. It is very important to note that the changes during this process are exclusively limited to the portions of the skin affected by lupus; even the faintest and smallest bits of diseased tissue go through the entire process and become visible on account of their swelling and reddening, while the actual scab-tissue in which the various stages of lupus have been completed remains unchanged.

The observation of the treatment of lupus with the remedy is so instructive and must be so convincing as regards the specific nature of the remedy that every one wishing to occupy himself with the study of this remedy should if possible make his first experiments with lupus.

Less marked, but still apparent to the eye and touch are the local reactions in tuberculosis of the lymphatic glands, of the bones and joints, etc., in which case swelling and increased painfulness, and in the more superficial parts also a reddening can be observed.

The reaction in the inner organs, especially the lungs is removed from our observation unless we consider the increased coughing and expectoration of the patients after the first injection a local reaction. At the same time we must assume that these parts undergo changes directly observed in the case of lupus.

The different forms of reaction described have appeared without exception in previous trials on the dose of .01 ccm. when any form of tuberculosis prevailed in the system, and therefore I trust that I am justified in assuming, that in the future this remedy will constitute an indispensible diagnostic auxiliary. We will be enabled to diagnose in doubtful cases of phthisis even then, when it is impossible to obtain reliable information concerning the nature of the ailment, by the presence of bacilli or elastic fibres in the sputum or by a physical examination. Glandular affectations, hidden tuberculosis of the bones, doubtful tuberculosis of the skin and the like will easily and reliably prove to be such. In case of apparently completed processes of tuberculosis of the lungs or joints it will be possible to show whether the process of the disease is in reality a complete one or establish the existence of centres from which later on the disease may spread like a fire from a live coal in the ashes.

But much more important are the specific qualities of the remedy than the aids it offers for the diagnosis.
