Negative Suggestions.—Some suggestions are valuable for the prophylaxis of complications. For instance, tuberculous patients must be warned not to indulge in breathing exercises without the express consent of the physician. So much is said in popular literature as to the value of breathing exercises that many a patient suffering from tuberculosis thinks that, not only may they be indulged in with impunity, but that they will surely do good and can do no possible harm. Nothing could be more erroneous. Many localized lesions have been diffused in this way and there is always danger that the strain will cause hemorrhage. Patients must be warned also to avoid any possible condition in which they might have to over-exert themselves. Because of the dust inevitably breathed during automobile riding, this pleasure must be denied to tuberculous patients as a rule, but even when they have recovered sufficiently so that this may be permitted they must be warned not to take long rides into the country lest the breaking down of the machine should place them under the necessity of walking a long distance. This idea should also be emphasized for rowing excursions, or trips by motor boat, for occasionally they lead to serious and exhausting exposure.
One negative suggestion should be given at the very initial stage to every patient in whom the presence of pulmonary tuberculosis has been recognized. This should be a warning to exercise the greatest care against permitting the development of constipation. Tuberculous patients must never strain at stool. Almost necessarily a certain number of tubercle bacilli are swallowed every day whenever pulmonary tuberculosis is at all active and they are constantly present in the digestive tract. If tuberculous patients then strain at stool, little abrasions of the mucous membrane of the rectum are caused in which tubercle bacilli find a favorable nidus. Ischio-rectal abscesses are common among the tuberculous and rectal fistulas often give much bother. When a tuberculous patient develops such a condition, a period of depression and discouragement will follow, for there is a curious tendency to depression associated with all lesions of the rectum. A pulmonary patient who has been doing well will often fail to make progress for months after the development of even a small ischio-rectal abscess.
CHAPTER III
NEUROTIC ASTHMA AND COGNATE CONDITIONS
For the consideration of its psychotherapy asthma may be divided into two forms—symptomatic and essential, or neurotic, asthma. Symptomatic asthma is a difficulty of breathing, the result of some interference with the circulation, as by heart disease, or with the oxidizing power of the blood, as by kidney disease, or various blood conditions, or from direct interference with respiration from some pulmonary affection. Essential asthma is not dependent on any organic condition, but is an interference with breathing without any distinct pathological condition in the lungs themselves or in the general circulation. There may be some emphysema, but not enough to account for the respiratory difficulty. It is spoken of as neurotic asthma, and the most careful investigations made of individuals who have died during a seizure has failed to give any sure pathological basis for the affection. Certain accompanying phenomena are worthy of note. The most interesting of these are Curschmann's spirals, which usually occur in the form of translucent pellets very characteristically described by Laennec as pearls. They are evidently formed in the finer bronchioles and show that the affection extends to the terminal portions of the bronchial system. In connection with these the so-called asthma crystals first described by Charcot and Von Leyden and sometimes called by their combined names are often found. Besides, there are a large number of eosinophiles in the sputum itself entangled within the filaments of the spirals and an eosinophila of the blood.
Etiology.—Not only are we ignorant of the reasons for these phenomena but there is even some doubt as regards the mechanism of the respiratory spasm itself. There is a general impression that the paroxysm is due to incapacity to inspire because of a paroxysmal spasm of the respiratory muscles. Gee in his "Medical Lectures and Aphorisms" [Footnote 30] rather leans towards the explanation that suffering is due not to any inability to fill the lungs but to incapacity to empty them when they have become over-distended with air. He tells the story related by Dean Swift of the old man whose barrel-shaped chest was fixed in spasm so full of air that the patient could not find room for the slightest additional breath. "If I ever get this air that is in me out," the patient declared to the Dean, "I will never take another breath."
[Footnote 30: Frowde, Oxford Univ. Press. 1908.]
It is important to differentiate symptomatic from neurotic or essential asthma. In symptomatic asthma the only assured treatment of the condition must come through amelioration of the organic condition causing the symptoms. Cardiac and renal asthma respond promptly to remedies which relieve critical conditions that may be present in the heart or kidneys. It must not be forgotten, however, that respiration is readily disturbed by mental influences. Where cardiac or renal disease causes interference with respiration this is much emphasized by the patient's unfavorable mental attitude toward it, or much relieved by keeping him from worrying over his condition. Even symptomatic asthma, then, has a definite place in psychotherapeutics, though [{365}] it would be serious not to recognize the underlying conditions and treat them. If the patient's attitude of mind is one of discouragement, the respiratory difficulties will continue to be a marked symptom of the case, even though the proper remedies for the relief of cardiac or renal conditions are administered.
Symptomatic Picture.—What is likely to be one of the most disturbing experiences of the young physician early in practice, especially if he has not before seen a typical case, is to be called to a patient suffering from a severe attack of asthma. Often the sufferer is sitting up in bed so as to get all the air possible, and, though the windows are wide open, he is gasping for breath, usually pleading for more air with a tense, anxious expression, starting eyes, and the sweat pouring from his forehead, while the accessory muscles of respiration, deeply engaged in moving his thorax to move air enough to keep him from stifling, emphasize his dyspnea. Occasionally a degree of cyanosis develops that is quite startling for the untrained observer. Most of those who see the symptomatic picture for the first time think that death is impending, and the patient himself, if he has not had a series of attacks, will fear a fatal termination. It appears impossible to believe that the next morning, within six or seven hours of this, the patient will, as a rule, be quite well and walking round in the enjoyment of apparent good health.
As a rule, the worse these cases seem in their intensity and the more the patient is anxious, the more surely are they merely of functional nervous origin; above all, the more complaints of lack of air and of fear of impending death that are made, the more likely is the patient to be all right within a few hours. Asthma looks as though it must be due to some serious organic condition. Of course, in many cases of difficult breathing, even with asthma-like attacks, there are underlying serious conditions of heart and kidneys that are extremely dangerous. As a rule, however, these do not produce the woeful pictures of purely neurotic asthma. Even when the basis of the asthma is an emphysema, which of itself is not dangerous and is quite compatible with long life, the attacks, though frequent and severe, are usually not so serious looking as those in which absolutely no pathological condition of the lungs, or heart, or kidneys can be found, and, indeed, in which there is absolutely no organic change to account for the extremely uncomfortable and even terrifying symptoms.
