DEFINITION.—A chronic inflammation of the mucous membrane of the pharynx, whether implicating the glandular structures or not, and commonly associated with similar chronic inflammation of contiguous structures.
SYNONYMS.—Chronic sore throat, Chronic angina.
Chronic pharyngitis presents in two varieties: 1, simple chronic pharyngitis (chronic catarrhal pharyngitis, chronic catarrhal sore throat), in which the disease does not affect, or affects but slightly, the glandular structures of the mucous membrane; and 2, follicular pharyngitis (granular pharyngitis, clergyman's sore throat), in which groups of the follicular glands of the mucous membrane are enlarged, and sometimes inflamed.
ETIOLOGY.—The predisposing causes of chronic catarrhal pharyngitis are those enumerated under the head of the acute form of the affection, and the exciting causes are repeated attacks of the acute malady.
The predisposing causes of chronic follicular pharyngitis are overcrowding, and sedentary occupations; and the exciting causes are chiefly improper use of the voice and exposure to local irritations, mechanical and chemical, including too free use of condiments, tobacco, and alcohol, gormandizing, and the alternations of hot food, cold drinks, ices, and hot drinks at meals. It is not so often a direct sequel of attacks of acute sore throat as a result of prolonged catarrhal pharyngitis; and sometimes it appears to be chronic, so to speak, from the outset.
Both forms of chronic pharyngitis are frequently associated with chronic inflammations of the mucous membranes elsewhere, particularly of the nasal passages and of the stomach, and, to a less extent, of the genito-urinary apparatus; the entire train of phenomena, in some instances, being due to passive congestion dependent upon impaired cardiac power. Similarly, it presents at times as one of the accompaniments of exophthalmic goitre. It is often associated with phthisis, and is sometimes found in phthisical subjects prior to the detection of the pulmonary disease. It is sometimes coincident with chronic cutaneous eruptions, and may depend on the same causes, whether dietetic or nervous.
Uterine disturbances may give rise to chronic pharyngitis, probably by reflex nervous influence, and so do other chronic and dispiriting complaints. In like manner, depression of spirits and impairment of bodily vigor from domestic, financial, and social chagrin provoke a train of phenomena in which chronic pharyngitis may be a prominent manifestation.
PATHOLOGY AND MORBID ANATOMY.—Simple chronic pharyngitis is a chronic catarrhal inflammation of the mucous membrane and submucous connective tissue of the pharynx, with irregular hyperplasia of all the histological elements, chiefly affecting the epithelial layers and the most superficial strata of the submucosa. The pharynx, the posterior surface of the palate, and the pharyngo-palatine folds are the structures most generally implicated, but the glosso-palatine folds, the base of the tongue, and even the anterior surface of the palate, are sometimes involved. At an advanced stage of the affection extension may take place to the vault of the pharynx and the posterior nasal outlets, and in occasional instances to the larynx.
The initial hyperæmia of diffuse congestion finally leads to permanent dilatation of tracts of capillaries varying in area and mode of distribution, sometimes recalling the territorial outlines upon a map. The mucous membrane is bright red in color and irregularly thickened, sometimes into prominent welts or folds. The palate is often relaxed. Hypersecretion takes place over the entire diseased surface, and there is considerable desquamation of turbid epithelium, which sometimes accumulates in masses. Glands are dilated and hypertrophied here and there, but not in every instance, or if so indiscernibly, at least, to the naked eye.
In some cases enlarged follicles are very prominent in the infra-tonsillar space, between the anterior and posterior palatine folds, and along the lateral walls of the pharynx down toward the base of the tongue. The circumvallate papillæ may also be enlarged, and the fungiform papillæ are sometimes very prominent and deeply congested.
In the folliculous variety of the disease the hyperplasia affects chiefly the mucous glands and follicles, isolated or in groups, together with zones of connective tissue surrounding them and the epithelial investment of the mucous membrane in their immediate neighborhood. A number of small projections, from the size of pinheads to that of peas, mostly somewhat hemispheroidal, sometimes ellipsoidal or quite irregular in configuration, stud the pharynx irregularly. When clustered they are more apt to occupy the lateral angles of the pharynx. In this locality indeed the chains of glands and their enveloping mucous membrane sometimes present in longitudinal ridges which simulate additional or adventitious post-palatine folds. The projections are usually opaque, deeper in color than the surrounding congested mucous membrane, and velvety from loss of squamous epithelium. Sometimes they are translucent, as if filled with colloid material, probably retained and degenerated secretion. Very often their contents undergo caseous degeneration, and sometimes even calcification—a variety designated tubercular by Green, Gibb, and others, but far different histologically from true tuberculosis of the pharyngeal glands, which does occur occasionally in phthisical patients.
Delicate red lines of engorged capillaries usually surround the base of these projections. There is great disposition to the accumulation of viscid, discolored mucus on the surface of the mucous membrane. As the disease progresses all the processes become more widely extended, until finally nearly the entire pharyngeal and oral mucous membrane becomes involved. The soft palate becomes relaxed and the uvula thickened and elongated, sometimes to an extreme degree. Chronic folliculous tonsillitis exists in many cases.
When either form of chronic pharyngitis continues for a long while unchecked, there may result atrophy of the glandular structures and epithelial elements generally, giving rise to pharyngitis sicca or atrophic pharyngitis (so-called dry catarrh). There is then but scanty secretion, and this dries rapidly upon the surface of the thin mucous membrane, which becomes rough, inflexible, and glazed.
SYMPTOMATOLOGY.—Cough, expectoration, impairment of voice, dysphagia, and uncomfortable sensations in the throat present in various degrees according to the stage of the disease and the temperament of the patient. Hemming and hawking to clear the throat often become habitual, especially in cases associated with chronic internal rhinitis, being provoked in many instances by secretory products which drop into the pharynx or glide along its walls. It is sometimes important to distinguish this habit from the cough of laryngeal or bronchial irritation.
In cases associated with chronic gastritis the loss of appetite and consequent emaciation accompanying the symptoms of pharyngitis sometimes lead friends of the patient to a mistaken diagnosis of consumption; and when, as is not infrequent, chronic bronchitis also coexists, even the physician may be misled.
In many instances of chronic folliculous pharyngitis evidently of long standing, and accidentally discovered at times to the surprise of the patient, no history of the classical group of symptoms can be obtained.
DIAGNOSIS.—The diffuse congestion of the mucous membrane and the absence of marked involvement of the follicles are, with the history of the case, the main discriminative features in the diagnosis of chronic catarrhal pharyngitis. The regular or irregular masses of tissue projecting beyond the general surface of the mucous membrane are the distinguishing characteristics of chronic folliculous pharyngitis. The vascular network of dilated capillaries mapping the surface into numerous irregular small areas of different sizes is not peculiar to either variety.
PROGNOSIS.—The prognosis of chronic catarrhal pharyngitis is favorable when no irremediable malady of body or mind exists. Much depends on the practicability of improving the dietetic and hygienic environment of the patient. The prognosis is likewise good in chronic folliculous pharyngitis under favorable surroundings, so far as relief from suffering is concerned; but the follicles, when long hypertrophied, so rarely undergo absorption under any treatment that their destruction becomes necessary—quite a different thing from their cure. The enlarged follicles once destroyed, the collateral irritative inflammation caused by them usually subsides. Impairment of voice, a result of the disease, may be remedied in young subjects, who will learn to use the voice with the abdomen in distension; but much improvement cannot be expected in old subjects and in those in whom the disease has been produced by improper methods of declamation, which are beyond correction.
TREATMENT.—In chronic catarrhal pharyngitis constitutional treatment adapted to the diathetic condition is required in the first instance. Alkaline laxatives are usually indicated by the irregularly coated tongue and the tendency to costiveness. These may be advantageously administered in half a pint of hot water one hour or so before meals, with a view of washing the stomach free from accumulations of mucus, epithelium, and retained products of digestion and decomposition, so that its condition may be improved for the reception and digestion of the ensuing meal. Topical medication of the throat is likewise requisite. This should be of a soothing character. Mild astringents are applicable, but strong astringents are often actually injurious. Silver nitrate and cupric sulphate in stick or strong solution should not be used; but sprays of dilute solutions (one or two grains to the ounce of distilled water), twice or thrice a day, are often of service. Zinc sulphate (five grains to the ounce) may be used in the same manner. Zinc chloride (ten grains to the ounce), carefully applied to the surface daily with a broad brush or soft cotton wad, is a useful remedy. Tannin in ether sometimes answers admirably, a delicate film being left for some time on the surface. Solutions of bismuth nitrate or borate in glycerin applied locally often relieve uneasiness. A broad flat brush is the best instrument for making these applications, placed low in the pharynx so as to paint the entire posterior wall by a single movement from below upward.
For home use, sprays, three or four times a day, of tar-water, containing five or ten grains to the ounce, of sodium borate or bicarbonate, or sodium, potassium, or ammonium chloride, or sodium, potassium, or ammonium iodide, are soothing and efficacious, and much superior to gargles. They are often preferred warm. Demulcent lozenges (gelatin, acacia, althæa, glycyrrhiza) slowly dissolved in the mouth often relieve topical discomfort.
Much more active treatment is required in chronic folliculous pharyngitis. Judicious constitutional treatment is of great importance. Topical medication is of equal importance. In recent cases of moderate intensity the ordinary treatment for the catarrhal variety sometimes suffices. In cases of long standing strong solutions of silver nitrate (sixty to one hundred and twenty grains to the ounce), carefully applied with the broad flat brush twice or thrice a week, are often of great remedial effect. Iodine (one drachm to the ounce of glycerin), alone or in combination with equal parts of carbolic acid, applied daily, may be serviceable in cases unimproved by the silver nitrate. Dilatation of the capillaries may sometimes be benefited by applications of ergot (fluid extract) or ergotin (grs. x-xx to the ounce). Enlarged follicles of long standing are rarely amenable to astringent and alterant topical treatment. They require destruction. The agent to be used is a matter of indifference as a rule, and, according to the taste or resources of the practitioner, may be the solid silver nitrate, caustic potash, London paste, zinc chloride, or the incandescent cautery, whether heated by fire, hot naphtha, or electricity.
The sprays and lozenges already mentioned are useful in this variety of pharyngitis also. They may be medicated with sedative ingredients according to indications for the relief of pain and discomfort.
In cases resisting the plan of treatment suggested mercuric chloride may be successfully used, both internally (gr. 1/16 two or three times a day) and in spray, a drachm or less night and morning (one grain to four ounces). External counter-irritation by repeated blistering over the larynx and under the angles of the jaws is useful in some instances. During treatment the voice should be used as sparingly as practicable.
In chronic atrophic pharyngitis the treatment, constitutional and local, should be such as favors secretion from mucous membranes—internally, cubeb, pyrethrum, calamus, xanthoxylum, jaborandi, ammonium chloride; topically, sprays, four or more times a day, of hot water, glycerin and water, ammonium chloride. Patients sleeping with the mouth open should wear an apparatus, extemporized or made to order, to keep the lower jaw closed in sleep.
DEFINITION.—A specific inflammation of the mucous membrane of the pharynx or of the mucous membrane and submucous tissues, the result of syphilis, and often associated with like disease in contiguous structures.
SYNONYMS.—Pharyngitis syphilitica, Pharyngitis specifica, Syphilitic sore throat, Syphilis of the pharynx.
ETIOLOGY.—Contamination by syphilitic virus is the sole cause, whether by direct inoculation or by systemic poisoning, hereditary or acquired. Direct inoculation proceeds from primary sores on the lips, tongue, cheek, and hard palate, themselves the result of actual contact with sores in other individuals. Initial sores have been seen upon the tonsils, palatine folds, pharynx, and even the epiglottis. Direct inoculation from secondary sores may be communicated by the tooth-brush, blow-pipe, pipe-stem, trumpet, mouth-piece of feeding-bottle, pap-boat, or similar article previously used by an infected individual. Uncleansed surgical instruments convey the disease in like manner.
PATHOLOGY AND MORBID ANATOMY.—Syphilitic pharyngitis—or, more strictly speaking, syphilitic sore throat—occurs in all varieties, primary, secondary, tertiary, and hereditary. Secondary manifestations are the most frequent, and primary sores the most infrequent. The primary sore is soft in some instances, and hard in others. Phagedænic ulceration may ensue. Secondary manifestations are usually bilateral, and often symmetric in configuration and distribution. They appear from a few weeks to a few months after infection, and are among the most frequent early manifestations of secondary syphilis. The inflammatory process begins in erythema, usually diffuse, often punctated, sometimes in patches. It extends from above downward more frequently than in the reverse direction, but may spread in any direction. The lesion commences upon the soft palate and tonsils more frequently than on the pharynx, but may commence in any portion of the oro-guttural cavity. Tumefaction ensues, with lividity of the surface. The epithelial cells become distended; the resulting opalescence, somewhat characteristic, eventually subsides into a central opacity, the true mucous patch or condyloma latum. Mucous patches vary in size from mere specks to large irregular surfaces, often the result of coalescences. They sometimes become red and granular and covered with purulent products. Microscopically (Cornil), they consist of thickened epithelium upon a base of proliferated lymphoid cells, which often infiltrate the deeper tissues extensively. They may disappear in the course of a few weeks by resolution and absorption. Sometimes suppuration occurs in small superficial abscesses which discharge upon the surface. Several abscesses discharging simultaneously in coalescence, an extensive ulcer may result, which, in repair, leaves a cicatricial trace of its site. Flat and circular bluish-white patches, due to thickening of epithelium, appear after the first year of constitutional syphilis, and may exist in association with the true mucous patch. They bleed readily on rough handling, but rarely undergo ulceration.
Tertiary manifestations may present within a few months after infection or not until many years. Gummatous infiltration of the connective tissue, diffused or circumscribed (syphiloma), follows diffuse or localized erythema, and then the gummata break down, discharge by ulceration, and leave deep-seated irregular ulcers with undermined edges and surrounded with inflammatory areolæ. These manifestations are much more frequent in the palate than in the pharynx, and the ulcerative process often destroys the uvula and large portions of the palate and palatine folds. When the pharynx and posterior surface of the palate are both ulcerated, cicatricial adhesions are sometimes inevitable, and thus serious stricture of the suprapalatine pharyngeal canal may ensue. The lesion may be quite limited in extent or may involve the entire pharynx. The ravages may become sufficiently extensive to involve the vertebra and the skull or to perforate the large blood-vessels. Cicatrization in the pharynx is vertical or stellate as the rule, and the peculiar pallid lustre of the cicatrices is quite characteristic of the syphilitic lesion. In many instances secondary and tertiary manifestations commingle. Ulceration is then more likely to extend superficially than in depth.
Hereditary manifestations pursue much the same course as tertiary manifestations. They usually occur before puberty, but are occasionally delayed until after maturity. Deferred tertiary and late hereditary manifestations sometimes present the characteristic ulceration of the commingled secondary and tertiary disease; and this form of ulceration is often incorrectly attributed to scrofulosis and to lupus.
SYMPTOMATOLOGY, COURSE, DURATION, COMPLICATIONS, AND SEQUELÆ.—The subjective symptoms of syphilitic pharyngitis are those of erythematous and ulcerative pharyngitis of like grade, except that there is very little pain. The course is chronic unless specific treatment be instituted, when prompt repair may be expected unless the general health has been much undermined. The duration is indefinite. The manifestations subside under treatment, and recur if it is not sufficiently prolonged. Complications occur with similar manifestations of syphilis in adjacent or contiguous or distant structures, as may be. The most frequent sequel in neglected cases is cicatricial stricture.
DIAGNOSIS.—Bilateral inflammation in symmetric distribution is very characteristic of syphilis. Irregular ulcers with undermined borders and surrounded by inflammatory areolæ are similarly characteristic. Acknowledged history of syphilis or the detection of syphilitic manifestations elsewhere serves to confirm the diagnosis. In cases of doubt a few days' treatment with specific remedies in large doses will almost invariably serve to clear up the diagnosis.
PROGNOSIS.—The prognosis as to life is good unless the ulcerations have become so extensive as to threaten perforation into blood-vessels or the patient has become greatly debilitated. The prognosis as to freedom from cicatricial adhesions and stricture is not good in the presence of lesions which have destroyed large territories of tissue, even under very careful management.
TREATMENT.—Specific medicines in positive doses constitute the most effectual treatment. Mercury is indicated in secondary lesions. Extensive ulcerative tertiary and hereditary lesions are peculiarly susceptible to large doses (30 to 90 or more grains daily) of potassium iodide, under the influence of which they often heal without any local applications whatever. As soon as a positive impression has been produced the dose may be diminished. The parts should be kept clean and comfortable by periodic douching with sprays of alkaline solutions, or, what is still more serviceable, with a ten-volume solution of hydrogen peroxide diluted with one or more parts of distilled water. The best local application to the edges of the pharyngeal syphilitic ulcers is the solid cupric sulphate. Chromic acid (1:8) is a serviceable local stimulant to indolent ulcers. Necrosed fragments of bone should be removed. Should any impediment to respiration take place during administration of the iodides, oedema of the larynx may be suspected, and should be looked for. Professional supervision is requisite for many months after the lesions have healed. Cicatricial sequelæ of stricture require surgical interference.
DEFINITION.—Inflammation of the oesophagus.
SYNONYMS.—Inflammatory dysphagia, Inflammation of the gullet.
Oesophagitis may be acute or chronic. Either form may be idiopathic, deuteropathic, or traumatic.
DEFINITION.—Acute inflammation of the gullet.
SYNONYM.—Oesophagitis acuta.
HISTORY.—Until the publication in 1829 of a thesis by J. T. Mondière entitled Recherches sur l'Inflammation de l'Oesophage, et sur quelques points de l'anatomie pathologique de cet organ, little study had been devoted to acute inflammation of the oesophagus; and since that time Mondière's researches have been largely utilized by subsequent writers. It has been taken for granted that Galen's mention of pain in the oesophagus1 has indicated his recognition of the disease. Fernel2 mentions phlegmon of the oesophagus; Honkoop3 describes inflammation of the oesophagus; J. P. Frank4 describes an oesophageal angina; and Joseph Frank5 seems to have been the first author to use the term oesophagitis. Since the publication of Mondière's monograph the principal systematic descriptions have been those of Hamburger6 Von Oppolzer7 Zenker and Ziemssen8 Luton,9 and Bernheim.10

ETIOLOGY.—Acute oesophagitis is quite a rare disease. It occurs idiopathically, deuteropathically, and traumatically—traumatically far the most frequently, and idiopathically least frequently. It is doubtful whether any special predisposing causes of oesophagitis can be indicated. Nevertheless, infancy has been so cited by some authors (Mondière, Billard, Behier, and Steffan). Slight idiopathic catarrhal—or rather erythematous—oesophagitis occasionally ensues in the adult from sudden or prolonged exposure to cold and moisture, and under such circumstances may sometimes be regarded as rheumatic in origin, subsiding after a few hours' continuance, to be immediately succeeded by manifestations of articular rheumatism, acute or subacute, as in some analogous examples of rheumatic pharyngitis. Exceptionally, severe oesophagitis may follow a simple cold (Noveene, cited by Bernheim), or presents as an extension of sore throat, the result of cold (Graves11). It is induced also by the habitual use of very hot drinks and food, and occasionally by the opposite extremes, the use of very cold articles of food and drink (Mondière, Bourguet, Hamburger). The abuse of tobacco and alcohol is alleged as quite a frequent cause of mild oesophagitis, usually occurring, however, in association with pharyngitis from the same causes.
11 Lon. Med. and Surg. Journ., 1836-37, No. 172, and Clinical Lectures, Dublin, 1864, p. 592.
Oesophagitis sometimes follows the deglutition of irritating medicines or moderately caustic poisonous substances not sufficiently acid to produce veritable traumatic oesophagitis. Mercury, codeina, and particularly tartar emetic, are cited as capable of exciting oesophagitis.
Large doses of tartar emetic, as formerly administered in pneumonia (Laennec12), sometimes produced a peculiar form of pustulous oesophagitis, not unlike the pustulous oesophagitis sometimes occurring as part of the local manifestations of small-pox.

Deuteropathic catarrhal oesophagitis occurs sometimes as an extension of catarrhal pharyngitis on the one hand, and of catarrhal gastritis on the other. It also occurs in scarlet fever, measles, and typhus fever. It is likewise consecutive to the various diseases and surgical lesions of the tube itself. Parasitic oesophagitis occurs as an extension of parasitic stomatitis or thrush. Deuteropathic circumscribed phlegmonous oesophagitis is sometimes produced by extension of inflammation from softened caseous bronchial glands at the bifurcation of the trachea, and by pressure from mediastinal tumors, aneurism of the aorta, etc.
Pseudo-membranous oesophagitis is almost always deuteropathic. It has been encountered chiefly in association with pseudo-membranous pharyngitis or diphtheria, and with croupous pneumonia, but likewise in enteric and typhus fever, in cholera and in dysentery, in measles, scarlatina, and small-pox, in nephritis, tuberculosis, carcinoma, and pyæmia.
In a case of hysteria, to be mentioned later, the entire epithelial coat of two-thirds of the oesophagus was discharged by emesis. In this respect the local disease—in that instance at least—resembles pseudo-membranous enteritis.
Traumatic oesophagitis is produced by the deglutition of corrosive substances, which destroy portions of the mucous membrane in their passage or excite a suppurative inflammatory process, or is produced by the passage of foreign bodies of sharp and irregular contour, or by the passage of surgical appliances, whether used for actual operations or for explorations merely.
In rare cases traumatic oesophagitis is the result of wounds with firearms or other weapons.
Phlegmonous oesophagitis may be the result of disease or injury of the interior of the oesophagus, or of its external coat by extension of disease from tissues surrounding it. Foreign bodies, arrested in the oesophagus or wounding it in their passage to the stomach; injuries from surgical appliances, exploratory or operative, employed in treatment for foreign bodies in the tube or in cases of stricture and morbid growth; and chemical irritants swallowed by accident or design,—are the chief causes in the former class of cases; but pustulous and pseudo-membranous oesophagitis must likewise be regarded as occasional causes. The causes operating upon the exterior of the tube primarily are suppurative laryngitis and tracheitis, tumefaction and softening of bronchial and tracheal lymphatic glands, and caries of the spine. Isolated cases have been attributed to emboli in connection with valvular diseases of the heart (Parenski, cited by Daton), and to fits of anger (J. Frank and Rigal, cited by Daton). In certain cases the cause is unassignable, and is then usually attributed to some dyscrasia, syphilis in particular.
PATHOLOGY AND MORBID ANATOMY.—Acute oesophagitis presents both as a diffused inflammation and a circumscribed process, annular or irregular in contour. It does not appear from the post-mortem records consulted that any special portion of the tube is particularly liable to circumscribed inflammation, though the lower fourth appears most frequently affected. The inflammatory process may be simply superficial or erythematous, catarrhal or desquamative (Zenker and Ziemssen), or it may be phlegmonous, and thus interest the submucous tissues as well as the mucous membrane. This may terminate in abscess or in diffuse suppuration with ulcerations. In occasional instances gangrene ensues. Both in diphtheria and in croupous pneumonia, pseudo-membranous oesophagitis is an occasional complication; and the same process is said to have been observed in typhus fever, measles, scarlatina, cholera, pyæmia, dysentery, tuberculosis, and carcinoma (Von Oppolzer and others).
Pustulous oesophagitis occurs in small-pox, and occasionally follows the use of tartar emetic in large doses.
The morbid anatomy of acute idiopathic oesophagitis, though usually detailed in descriptions of the disease, must be known by theory much more than by demonstration, few examples coming under the inspection of the pathologist in time to distinguish the progressive stages of the inflammatory process, and still fewer being revealed by oesophagoscopy during life. The lesions most frequently observed post-mortem are thickening, softening, and desquamation of the epithelium, with very scanty accumulations of viscid mucus here and there upon the mucous membrane. The mucous membrane is seen to have suffered numbers of pinhead or slightly larger superficial circumscribed erosions, rounded or longitudinal, and likewise a few actual ulcerations. The follicles of the mucous membrane are often both swollen and hypertrophied, reaching the size of peas, especially in the upper portion of the tube.
The desquamation of the epithelium usually takes place in small patches. One case, however, has been recorded (Birch-Hirschfeld13) in which a young hysterical woman, after suffering three days with acute oesophagitis without assignable cause, ejected by emesis a membranous tube two-thirds of the entire length of the oesophagus, and shown under examination to have been the completely detached epithelial coat of the oesophagus, wholly normal in its upper layers and infiltrated with agglomerated round cells in its lower layers. It was supposed that the mass had been detached in consequence of acute subepithelial suppuration.
13 Lehrbuch der pathologische Anatomie, Ziemssen, 1877, p. 818; English translation, vol. viii. p. 140.
In addition to swollen and hypertrophied follicles there may be some evidence of ulcerative destruction of these follicles. Mondière and others declare that this folliculous inflammation and ulceration may exist without any other change whatever in the remaining constituents of the mucous membrane; and therefore this form of oesophagitis was termed folliculeuse by Mondière (folliculous oesophagitis). This form of the disease has been observed in typhus fever, in croup (Mondière), and in tuberculosis. Ulceration of the oesophagus occurs, likewise, in carcinoma and in oesophagitis from corrosive fluids, wounds, and other injuries.
In pseudo-membranous oesophagitis the exudation occurs usually in small circumscribed gray-yellow or brownish flakes or stripes distributed over different portions of the surface, more closely, however, at the upper portion of the tube. Superficial erosions are sometimes observed beneath these deposits, and occasionally ulcerations, at times sufficient to give rise to severe hemorrhage (Zenker and Ziemssen). Usually the mucous membrane is but slightly hyperæmic. In some instances pseudo-membrane is so massed in plugs as to occlude the cavity of the tube, as with obturators. In cases associated with pseudo-membranous gastritis the oesophageal manifestations are greatest in the vicinity of the cardiac extremity. Somewhat allied to pseudo-membranous oesophagitis, and apt to be confounded therewith, is the parasitic deposit of the Oïdium albicans in cases of thrush; in connection with which subject this point has already received attention.
The pustules of small-pox may interest any portion of the mucous membrane, but are most numerous at the upper portion of the tube. They may be discrete or confluent. The pustules from tartar-emetic poisoning are most numerous at the two extremities of the canal. It is contended that the so-called pustules of variolous oesophagitis are really superficial variolous ulcers, the antecedent specific lesions having been lenticular papules merely, with abrasion of the softened epithelial layer.14 Variolous oesophagitis may excite an accompanying catarrhal or pseudo-membranous oesophagitis. The local lesions, be they pustular or ulcerous, heal without cicatrices.
14 Virchow's Deutsche Klinik, 1858, No. 31, p. 306; Zenker and Ziemssen, op. cit., p. 146.
Phlegmonous oesophagitis presents both as a diffuse and as a circumscribed inflammation. Examined after death, there is abundant purulent infiltration into the submucous connective tissue, which has undergone destruction in portions of its extent. The infiltration pushes the folds of mucous membrane outward to the interior of the tube, and thus diminishes its calibre considerably when the infiltration is annular. The mucous membrane is congested, ecchymosed, and covered with mucus, and has usually suffered desquamation of portions of its epithelium. Ulcerations through the mucous membrane will have taken place in some instances. Cicatrices mark the location of ulcers which have healed.
In the diffuse variety the oesophagus is inflamed and swollen, as a whole, in proportion to the extent of the disease. In the circumscribed variety the morbid appearances are circumscribed. It has been known to continue into the stomach (Belfrage and Hederius, cited by Zenker and Ziemssen), and to extend therefrom (Ackermann, idem).
As described by Zenker and Ziemssen, chiefly from ten autopsies by themselves and one by Belfrage and Hederius, phlegmonous oesophagitis begins with a submucous purulent infiltration, transforming the areolar tissue into an apparent layer of pus, although microscopic examination shows the bundles of connective tissue to be intact at first. At a later period they become really destroyed, leaving mere crevices filled with pus. The mucous membrane, but little involved, may remain normal or may present the evidence of catarrhal inflammation, desquamation of epithelium, congestion, and slight deposits of mucus. The muscular coat, intact to the unaided eye, under the microscope gives some evidence of purulent infiltrations. The pus may finally escape through the mucous membrane, in extensive infiltrations, at several points, which give the parts a sieve-like appearance when the perforations are closely grouped.
Gangrene sometimes occurs as a result of intense phlegmonous oesophagitis, but this is far more rare than the gangrene supervening after injuries by caustic substances. Sometimes it results from capillary embolism (Rokitansky, Virchow, cited by Luton, op. cit.).
SYMPTOMATOLOGY, COURSE, DURATION, TERMINATION, COMPLICATIONS, AND SEQUELÆ.—The main subjective symptoms of oesophagitis are pain and difficulty in swallowing, with febrile phenomena superadded in severe cases. In simple oesophagitis of mild character these symptoms may be so slight as to be attributed to other causes or be disregarded altogether. In most instances there is a dull, steady pain beneath the sternum, some sense of impediment to deglutition or absolute pain in swallowing (odynphagia), and occasional regurgitation of viscid, glairy mucus, food, or acid products from the stomach. In severe cases the substernal pain is more acute and more diffused, and is frequently associated with pain between the scapulæ and to the left side. This latter pain may be attributable to acid from the stomach. Sometimes the pain is described as acute, especially during the passage of large boluses, particularly if they are very hot, or even very cold. The seat of pain, however, does not always indicate the seat of inflammation, even though the pain be always referred to the same locality. When the cervical portion of the tube is implicated, tenderness may sometimes be detected by external pressure or by special movements of the head and vertebræ.
The amount and character of the dysphagia vary greatly. Sometimes there is a sense of impediment to the passage of food, solid or liquid, or solid only, through and beyond the painful region. This sensation may be accompanied or be followed at a brief interval by regurgitation of food or mucus, or food enveloped with mucus, the latter in some instances tinged with blood. The deglutition or the regurgitation may be accompanied by spasm of the muscular coat of the oesophagus. The dysphagia is not always due to tumefaction of the mucous membrane, but usually in part to coexisting inflammation of the muscular coat or infiltration between the sheaths of muscular fibres, paralyzing their efforts at contraction.
There are no subjective symptoms which permit discrimination between desquamative catarrhal oesophagitis and folliculous oesophagitis. The only symptom particularly indicating pseudo-membranous oesophagitis is the expulsion of shreds of the membrane by hawking or by emesis; but a strong inference is justifiable when the ordinary symptoms of oesophagitis occur in cases of pseudo-membranous pharyngitis or croupous pneumonia.
Phlegmonous oesophagitis is indicated by the presence of pus or of dead mucous membrane in the matter regurgitated or vomited. In severe cases there is considerable febrile reaction. In children, convulsions may supervene from reflex irritation conveyed along the pneumogastric nerve.
The course of acute catarrhal oesophagitis is, as a rule, short, the pain and dysphagia usually subsiding in a few days, with complete resolution and no unfavorable sequelæ. When due to obstruction, the course is indefinitely prolonged. Sometimes it subsides into a mild or unsuspected chronic oesophagitis. In the symptomatic oesophagitis of febrile diseases, the course is longer and unequal. In severer forms and in phlegmonous oesophagitis, the disease may be protracted by suppuration, abscess, gangrene, perforation of the oesophagus, and other complications. It often terminates fatally—in three or four days in some cases—sometimes under symptoms of collapse. Cases may recover without important sequelæ, but stricture very often results from cicatricial complications. Chronic oesophagitis is a more frequent sequel of the phlegmonous variety than of the catarrhal. It, in its turn, may give rise to dilatation of the oesophagus, annular or diverticular, from detention of food and consequent pressure.
DIAGNOSIS.—The diagnosis will rest upon the interpretation of the coexistence of a certain number of the symptoms mentioned. Idiopathic phlegmonous oesophagitis may readily be mistaken for dorsal myelitis by the location of the pain—the more so that the spinal disease is occasionally attended with spasm of the oesophagus, and the myelitis by difficulty in deglutition; but the differentiation may be determined by the inability to produce oesophageal pain by pressure made along the dorsal vertebræ. In deuteropathic or traumatic phlegmonous oesophagitis, the history of the attack will indicate the probable nature of the malady, and prevent the mistake. Diffused oesophagitis is suspected when the general pain or the painful dysphagia appears to extend along the entire tract of the oesophagus, or at least a large portion of it.
Circumscribed oesophagitis is usually indicated by odynphagia at a certain point of the tube after completing the act of deglutition. The location of the inflammation can sometimes be determined by auscultation of the descent of the alimentary bolus or of a swallow of water (Hamburger), which may yield evidence to the ear of arrest or impediment to its passage. Auscultation of the oesophagus, however, is less useful in acute oesophagitis than in stenosis, stricture, and mechanical obstruction. When available in oesophagitis, the normal sound of the passage of water down the gullet becomes masked, and accompanied by that of regurgitative ascent of small bubbles of air. Sometimes there is a slight friction sound during the act of deglutition itself. In circumscribed oesophagitis, especially when annular, as is most frequently the case, sounds are heard attributable to marked obstruction to the descent of the bolus. Abscess cannot be positively diagnosticated until after its rupture and the appearance of pus in the matters regurgitated or otherwise expelled from the oesophagus.
Catheterism of the oesophagus is hardly justifiable as a method of diagnosticating oesophagitis, though proper enough when it becomes important to determine the locality of attendant obstruction.
It is important that inflammation of the oesophagus be differentiated from spasm, stricture, stenosis, carcinoma, and other oesophageal maladies; nearly all of which present the same main subjective symptoms—pain and impediment to deglutition. The history of the case is in itself a guide of great diagnostic value, often quite sufficient for the purpose; but in its absence or retention other data must be gathered.
Spasm of the oesophagus is most frequent in neurotic subjects. Its manifestations are often sudden. It is evanescent or intermittent. It is not a febrile affection. It is often overcome in a moment by catheterization.
Stricture presents often an additional symptom of oesophagitis, the regurgitation of mucus and food. The differentiation is made, in cases of doubt, by the passage of the bougie or catheter.
Carcinoma of the oesophagus, while recent, may present much similitude to oesophagitis, but as the case advances, the glandular involvements, the cachexia, the expulsion of cancerous fragments, and the vomiting of blood seem sufficient to prevent further confusion.
PROGNOSIS.—The prognosis is favorable in acute catarrhal oesophagitis, the manifestations often subsiding within a few days; sometimes, indeed, within a few hours, and that, too, without special medication. It is therefore largely dependent on the cause of the oesophagitis and the severity and extent of the malady. The only unfavorable prognostications arise from the impediment to nourishment and the complications which may ensue.
In presumptive pustulous oesophagitis from the use of preparations of antimony, the manifestations usually subside within a few days upon suspension of the remedy. Sometimes, however, these cases terminate fatally.
Pseudo-membranous oesophagitis is usually fatal in its significance, and the same may be said of the pustulous or ulcero-papular oesophagitis of small-pox.
Phlegmonous oesophagitis is of grave augury, though many cases recover. It may prove fatal within two or three days, though life is usually prolonged for several days, even in fatal cases. When not fatal, abscesses are apt to form, which, discharging internally or externally, are followed by stricture or fistulæ.
Both ulcerative oesophagitis and intense catarrhal oesophagitis may terminate in chronic thickening of the walls of the oesophagus and in cicatricial adhesions more or less extensive.
TREATMENT.—Mild oesophagitis requires no special treatment. The patient should be kept within doors, and be fed on rice-water, barley-water, and other mucilaginous articles of diet, so as to avoid all sources of local irritation. These drinks are usually better borne hot than cold, but sometimes cold is quite agreeable. When cold can be well borne the frequent deglutition of pellets of ice is useful as well as agreeable, and ice-cream becomes a medicinal article of diet.
In severe cases the measures indicated become still more requisite, and the use of the voice should be restrained in addition. All unnecessary efforts at deglutition should be avoided, and anodyne medicaments (opium, hyoscyamus, belladonna) should be added to the demulcent food or beverages. When swallowing is impracticable or very painful, nutriment should be given by the bowel, and medicines by the bowel or by the skin. Thirst may be allayed by retaining fragments of ice in the mouth from time to time, by rinsing the mouth with simple or acidulated water, by sucking the juice of acid fruits, or by allowing compressed effervescent lozenges to dissolve slowly in the mouth.
The external application of cold compresses, continuously or in frequent renewals, is also indicated.
Febrile phenomena require ordinary antiphlogistic medication. When this is impracticable, the indications may be met by using the cold bath or the wet sheet, and by administering antipyretics hypodermatically. Traumatic oesophagitis from a foreign body requires removal of the object if still in the oesophagus; that from swallowing alkalies is met by the use of acidulated beverages (vinegar and water, Orfila); that from swallowing acids, by the use of alkaline drinks, of which the handiest is usually soap and water. As soon as they can be procured this may be changed for lime-water and calcined magnesia. Theoretically, the carbonates of the alkalies are indicated likewise, but it is contended (Hamburger, Oppolzer) that the extrication of the carbonic acid gas renders mechanical rupture of the corroded oesophagus imminent. Subsequently, fresh water should be freely drunk, or be injected into the oesophagus when swallowing is impracticable. The subsequent treatment is to be instituted upon general principles.
