Deuteropathic tonsillitis is quite frequent in infancy, being excited by the infection of scarlet fever, diphtheria, measles, and small-pox, as discussed under these headings respectively. Under similar circumstances it occurs in the adolescent and the adult likewise. It is also produced in carcinoma and sarcoma of the tonsil.
Rheumatic tonsillitis, a deuteropathic variety, is most prevalent during atmospheric changes.
Herpetic tonsillitis, often a deuteropathic variety, seems sometimes of nervous origin exclusively. It is sometimes traceable to defective drainage. It is sometimes prevalent during epidemics of diphtheria, when its membranous character renders it extremely liable to be mistaken for the tonsillitis of diphtheria.
Traumatic tonsillitis occurs occasionally. The causes are—inspiration of irritant gases, the deglutition of chemically acrid substances, the accumulation of calcareous concretions in the crypts or in the lacunæ, direct and indirect gunshot and other wounds, the impaction of fish-bones, fragments of toothpicks, cherry-stones, and other foreign bodies, and the like.
Mycotic tonsillitis is due to the development of a cryptogam upon tonsils probably already in a state of catarrhal inflammation in individuals with health impaired by previous disease or unfavorable hygienic influences.
SYMPTOMATOLOGY, COURSE, DURATION, TERMINATIONS, COMPLICATIONS, AND SEQUELÆ.—The onset of tonsillitis, sometimes preceded by headache and general malaise, is often accompanied by a chill, pyrexia following within twenty-four hours. The temperature may reach 105° F., being at its maximum, as a rule, about the third day. It is rarely below 101° F. The pulse is accelerated to 120 beats per minute. Simultaneously with the constitutional symptoms local distress is usually manifested, but either set of disturbances may precede the other by several hours or by an entire day. Heat and soreness of the throat are early complained of, gradually increasing in severity to actual pain. The pain may become intense, especially during deglutition. When the posterior palatine fold is put upon the stretch, additional pain is referred to the ear, for this fold encloses the staphylo-salpingeus muscle, which runs from the palate to the pharyngeal orifice of the Eustachian tube. This pain in the ear, sometimes the principal cause of complaint, is often premonitory of suppuration. Noises in the ears on the one hand, and impairment of hearing on the other, often attend extension of the inflammation in this direction, the enlarged tonsil sometimes pressing the posterior palatine fold against the pharyngeal orifice of the Eustachian tube.
On inspecting the throat early in the disease, one of the tonsils will be seen to be swollen into an irregularly tumid, much-inflamed mass, usually of a vivid red color. Occasionally both tonsils are involved simultaneously, but this is far less frequent than involvement of the second tonsil a few days later or after subsidence of the process in its fellow. In many instances the inflammation affects one tonsil only.
The inflammatory process is seldom confined to the tonsil. All the structures of the throat, even to the base of the tongue, are often involved, and it is rarely indeed that the anterior palatine fold, distended over the surface of the tumefied gland, escapes inflammation. It is this stretching of the anterior palatine fold which occasions much of the exquisite pain that forms so prominent a subjective symptom in severe cases. The soft palate, hanging forward in the cavity of the pharynx, is often inflamed or intensely congested, and the uvula tumefied, elongated, and oedematous. It may be flaccid upon the posterior part of the tongue or hang immediately over the epiglottis or upon it, and induce painful and tiresome efforts at deglutition and expectoration to relieve the consequent titillation. Sometimes it adheres by viscid secretion to the side of the swollen tonsil.
The inflamed tonsil or the tonsil and its coverings project far into the cavity of the pharynx, often as far as the middle line, touching its fellow when both are involved, so that ulceration sometimes ensues at the points of contact. The posterior surface of the anterior palatine fold sometimes becomes unfolded, as it were, in the tumefaction of the gland, and remains stretched over it in a thin continuous layer without any line of demarcation. The swollen palate projects upon the enlarged tonsil like a shelf, from which depends the uvula, the latter being often oedematous, usually anteriorly, but sometimes posteriorly.
Inflammation of the connective tissue about the lower jaw, especially when at or near the articulation, often renders it difficult or even impracticable to open the mouth sufficiently to permit direct inspection of the parts; but it is rarely that sufficient space cannot be made to allow partial protrusion of the tongue on the one hand, and the introduction of a fore finger for exploratory purposes on the other, though both of these acts are sometimes impossible. The tumefaction of the parts impairs the freedom and ease of deglutition, which may become so painful as to prevent the swallowing of the saliva, which then may dribble from the mouth.
