INTERPRETATION OF SYMPTOMS.

We shall refer to a few symptoms which any unprofessional reader may readily observe and understand.

Position of Patient. When a patient is disposed to lie upon his back continually during the progress of an acute disease, it is a sign of muscular debility. If he manifests no desire to change his position, or cannot do so, and becomes tremulous at the least effort, it indicates general prostration. When this position is assumed, during the progress of continued fever, and is accompanied by involuntary twitching of the muscles, picking of the bed-clothes, etc., then danger is imminent and the patient is sinking. Fever, resulting from local inflammation, does not produce muscular prostration, and the patient seldom or never assumes the supine position. If this inflammation is in the extremities, those parts are elevated, in order to lessen the pressure of the blood, which a dependent, position increases.

For example, let us change the scene, and introduce a patient with head and shoulders elevated, who prefers to sit up, and who places his hands behind him and leans back, or leans forward resting his arms and head upon a chair. The next week he is worse, and no longer tries to lie in bed, but sits up all the time; note the anxious expression of countenance, the difficult or hurried breathing, the dry and hacking cough, and observe that the least exertion increases the difficulty of respiration and causes palpitation of the heart. These plain symptoms signify thoracic effusion, the collection of water about the lungs.

The Countenance displays diagnostic symptoms of disease. In simple, acute fevers, the eyes and face are red and the respiration is hurried; but in acute, sympathetic fever, these signs are wanting. We cannot forget the pale, sharp, contracted, and pinched features of those patients whose nostrils contract and expand alternately with the acts of respiration. How hard it was for them to breathe. The contraction and expansion of the nostrils indicate active congestion of the lungs.

As a general rule, chronic inflammation of the stomach, duodenum, liver, and adjacent organs, imparts a gloomy expression to the countenance, at the same time the eye is dull, the skin dusky or yellow, and the motions are slow. But in lung diseases, the spirits are buoyant, the skin is fair, and the cheeks flushed with fever and distinctly circumscribed with white, for delicacy and contrast, almost exceed the hues of health in beauty. Note, too, the pearly lustre and sparkling light of the eye, the quivering motion of the lips and chin, all signs of pulmonary disease.

The Story of Sexual Abuse is plainly told by the downcast countenance, the inability to look a person fairly in the face, the peculiar lifting of the upper lip and the furtive glance of the eye. The state of the mind and of the nervous system corroborates this evidence, for there seems to be a desire to escape from conversation and to elude society. The mind seems engrossed and abstracted, the individual appears absorbed in a constant meditation, he is forgetful and loses nearly all interest in the ordinary affairs of life. The whole appearance of a patient, suffering from spermatorrhea, is perfectly understood by the experienced physician, for the facial expressions, state of mind, and movements of the body, all unconsciously betray, and unitedly proclaim his condition.

Tongue. Much may be learned from the appearance, color, and form of the tongue, and the manner of its protrusion. If pale, moist, and coated white, it indicates a mild, febrile condition of the system. If coated in the center, and the sides look raw, it indicates gastric irritation. If red and raw, or dry and cracked, it is a sign of inflammation of the mucous membrane of the stomach. If the inflammation is in the large intestine, the tip of the tongue presents a deep red color, while the middle is loaded with a dark brown coating. When the tongue is elongated and pointed, quickly protruded and withdrawn, it indicates irritation of the nerve-centers, as well as of the stomach and bowels. If tremulous, it denotes congestion and lack of functional ability; this may be observed in congestive fevers.

Pulse. Usually the pulse beats four times during one respiration, but both in health and disease its frequency may be accelerated or retarded. In adults, there are from sixty-five to seventy-five beats in a minute, and yet in a few instances we have found, in health, only forty pulsations per minute. But when the heart beats from one hundred and twenty to one hundred and forty times a minute, there is reason to apprehend danger, and the case should receive the careful attention of a physician.

Irregularity of the pulse may be caused by disease of the brain, heart, stomach, or liver; by the disordered condition of the nervous system; by lack of muscular nutrition, as in gout, rheumatism, or convulsions; by deficiency of the heart's effective power, when the pulse-wave does not reach the wrist, or when it intermits and then becomes more rapid in consequence of septic changes of the blood, as in diphtheria, erysipelas, and eruptive fevers.

Pain. The import of pain depends on its seat, intensity, nature, and duration. An acute, intense pain usually indicates inflammation of a nerve as well as the adjacent parts. Sharp, shooting, lancinating pains occur in inflammation of the serous tissues, as in pleurisy. A smarting, stinging pain attends inflammation of the mucous membrane. Acute pain is generally remittent and not fixed to one spot. Dull, heavy pain is more persistent, and is present in congestions, or when the substance of an organ is inflamed, and it often precedes hemorrhage. Burning pain characterizes violent inflammations involving the skin and subjacent cellular tissue, as in case of boils and carbuncles. Deep, perforating pain accompanies inflammation of the bones, or of their enveloping membranes. Gnawing, biting, lancinating pain attends cancers.

The location of pain is not always at the seat of the disease. In hip-disease, the pain is not first felt in the hip, but in the knee-joint. In chronic inflammation of the liver, the pain is generally most severe in the right shoulder and arm. Disease of the kidneys occasionally produces numbness of the thigh and drawing up of the testicle, and commonly causes colicky pains. Inflammation of the meninges of the brain is often indicated by nausea and vomiting before attention is directed to the head. These illustrations are sufficient to show that pain often takes place in some part remote from the disease.

In chronic, abdominal affections, rheumatic fevers, gout, and syphilis, the entire system is thrown into a morbid state, the nervous system is disturbed, and wandering pains manifest themselves in different parts of the body. Fixed pain, which is increased by pressure, indicates inflammation. If it be due only to irritation, pressure will not increase it. Some rheumatic affections and neuralgia not only bear pressure, but the pain diminishes under it. Permanent pain shows that the structures of an organ are inflamed, while intermittent pain is a sign of neuralgia, gout, or rheumatism. Absence of pain in any disease, where ordinarily it should be present, is an unfavorable sign. Internal pain, after a favorable crisis, is a bad omen. Or, if pains cease suddenly without the other symptoms abating, the import is bad. If, however, pain and fever remit simultaneously and the secretions continue, it is a favorable sign.

A dull pain in the head indicates fullness of the blood-vessels from weakness, low blood, or general debility. It may be caused by taking cold, thus producing passive congestion of the brain. It may proceed from gastric disturbance, constipation of the bowels, or derangement of the liver. Heaviness of the head sometimes precedes inflammation of the brain, or chronic disease of its membranes. A dull, oppressive pain in the head indicates softening of the brain, and is generally accompanied by slowness of the pulse and of the speech. A pulsating pain of the head occurs in heart disease, hysteria, and frequently accompanies some forms of insanity.

The Eye indicates morbid changes and furnishes unmistakable signs of disease. Sinking of the eye indicates waste, as in consumption, diarrhea, and cholera. In fevers it is regarded as a fatal symptom. A dark or leaden circle around the eye, seen after hard work, indicates fatigue and overdoing. If the mucous covering of the inner surface of the lids and the ball of the eye is congested and inflamed, it exhibits redness, and may indicate congestion or even inflammation of the brain.

A dilated pupil is often observed in catarrhal consumption, congestion of the brain, low fevers, and chlorosis.

The pupil contracts in inflammation of the meninges, when there is increased sensibility and intolerance of light, also in spinal complaints. In some diseases the lustre of the eye increases, as in consumption. But if it decreases with the attack of violent disease, it indicates great debility and prostration.

Examination of the Urine. All medical authors and physicians of education, freely admit and even insist upon the importance of critically examining the patient's urine, in all cases in which there is reason to suspect disease of the kidneys or bladder. In chronic affections it is particularly serviceable, especially in derangements of the liver, blood, kidneys, bladder, prostate gland, and nervous system. Many scholarly physicians have sadly neglected the proper inspection of the urine, because they were afraid of being classed with the illiterate "uroscopian" doctors, or fanatical enthusiasts, who ignorantly pretend to diagnose correctly all diseases in this manner, thus subjecting themselves and their claims to ridicule. Nothing should deter one from giving to this excretion the attention it deserves.

The urine which is voided when the system is deranged or diseased is altered in its color and composition, showing that its ingredients vary greatly. So important an aid do examinations of the urine furnish in diagnosing many chronic ailments, that at the Invalids' Hotel and Surgical Institute, where many thousands of cases are annually treated, a chemical laboratory has been fitted up, and a skillful chemist is employed, who makes a specialty of examining the urine, both chemically and microscopically, and reporting the result to the attending physicians. His extended experience renders his services invaluable. With his assistance, maladies which had hitherto baffled all efforts put forth to determine their true character, have frequently been quickly and unmistakably disclosed.

Microscopical Examination. This method of examination affords a quicker and more correct idea of a deposit or deposits than any other method. The expert, by simply looking at a specimen, can determine the character of the urine, whether blood, mucus, pus, uric acid, etc., are present or not. But when no deposit is present, then it is necessary to apply chemical tests, and in many cases the quantity of the suspected ingredient must be determined by analysis. As a detailed account, of the various modifications which the urine undergoes in different diseases, would be of no practical use to the masses, since they could not avail themselves of the advantages which it would afford for correct diagnosis, except by the employment of a physician who does not ignore this aid in examining his patients, we shall omit all further details upon the subject. For the same reason we shall not often, in treating of the different diseases in which examinations of the urine furnish such valuable aid in forming a diagnosis, make mention of the changes which are likely to have occurred.
