Tongue is a muscular organ associated with the function of deglutition,taste and speech.It acts as an easily accessible organ for the assessment of health of an individual and shows the state of hydration of the body.It is said that tongue is the mirror of the gastrointestinal system and any abnormal functioning of the stomach and intestines will be reflected on the tongue.
Some characteristic changes occur in the tongue in some particular diseases.That is why the examination of the tongue is very essential and will give some clues for diagnosis.All doctors examine the tongue and they consider the changes in size,shape,,colour,moisture,coating,nature of papillae and movements ect.
Appearance of tongue in some abnormal conditions:-
1) Movements of the tongue:-
a) In one sided paralysis of the body(hemiplegia)tongue moves towards the parylised side when protruded.
b) Tremulus movement of the tongue is seen in diseases like thyrotoxicosis,delirium tremens and parkinsonisum.Tremor is also seen in nervous patients.
c) In progressive bulbar palsy there will be wasting and paralysis of the tongue with fibrillation.Eventually the tongue gets shrivelled and lies functionless in the floor of the mouth.This condition is associated with dribbling of saliva and loss of speech.
d) In chorea(involuntary rhythmic movements) the patient may not be able to keep the protruded tongue in rest,it will be moving involuntarily.
2) Moistness of the tongue:-
The moistness of the tongue gives some indication about the state of hydration of the body.Water volume depletion leads to peripheral circulatory failure characterised by weakness,thirst,restlessness,anorexia,nausea,vomiting ,dry and parched tongue.
Dryness of the tongue is seen in following conditions.
a) Diarrhoea b) Later stages of severe illness c) Advanced uraemia d) Hypovolumic shock e) Heat exhaustion f) Hyponatraemia g) Acute intestinal obstruction h) Starvation i) Prlonged fasting.
3) Change in colour of tongue:-
a) Central cyanosis:-
Cyanosis is the bluish discolouration of the mucus membrane due to decrease in the amount of oxygen in the blood.This is seen in heart failure,respiratory failure and in anoxia.In cyanosis tongue,lips ect becomes pale bluish.
b) Jaundice:-
This is the yellowish discolouration of all mucus surfaces of the body (including tongue)due to increase of bilirubin in the blood.Jaundice is seen in hepatitis,bile duct obstruction,increased destruction of RBCs and ect...
c) Advanced uremia:-
This is the increase of urea and other nitrogenous waste products in the blood due to kidney failure.Here the tongue become brown in colour.
d) Keto acidosis:-
This is the acidosis with accumulation of ketone bodies seen mainly in diabetes mellitus.Here the tongue become brown with a typical ketone smell from the mouth.
e) Riboflavin deficiency:-
Deficiency of this vitamin (vitamin B2) produces megenta colour of the tongue with soreness and fissures of lips.
f) Niacin deficiency:-
Deficiency of niacin (vitamin B3)and some other B complex vitamins results in bright scarlet or beefy red tongue.
g) Anaemia:-
It is the decrease in haemoglobin percentage of the blood.In severe anaemia tongue becomes pale.
4) Coating on the tongue:-
a) Bad breath:-
The main cause for bad breath is formation of a pasty coating(bio film) on the tongue which lodges thousands of anaerobic bacteria resulting in the production of offenssive gases.Those who complain about bad breath may have thick coating on the posterior part of the tongue.
b) Typhoid fever:-
In typhoid fever tongue becomes white coared like a fur.
c) Candidiasis;-
It is a fungal infection which affects the mucus surfaces of the body.On the tongue there will be sloughing white lesions.
d) In diabetes and hypoadrenalism there will be sloughing white lesions.
e) Secondary syphilis:-
Syphilis is a sexually transmitted diseased caused by trepenoma pallidum infection.In secondary stage of this disease we can see mucous patches which are painless,smooth white glystening opalescent plaques which can not be scraped off easily.
f) Leokoplakia:-
Here white keratotic patches are seen on the tongue and oral cavity.This is a precancerous condition.
g) AIDS:-
In these patients hairy leukoplakia is seen.
h) Peritonitis:-
It is the inflammation of the peritonium(inner covering of abdominal cavity which also covers the intestines and keep them in position) in this condition there is white furring of the tongue.
i) Acute illness:-
Furring is also seen in some acute diseases.
5) Papillae:-
These are small projections on the rongue associated with taste.There are different type of papillae on the healthy tongue.In some diseases there are some abnormal changes which are following.
a) Hairy tongue:-
This condition is due to elongation of filiform papillae seen in poor oral hygeine ,general debility and indigestion.
b) Geographic tongue:-
Here irregular red and white patches appear on the tongue.These lesions looks like a geographic map.The excact cause is not known.
c) Median rhomboid glossitis:-
In this condition there is smooth nodular red area in the posterior mid line of the tongue.This is a congenital condition.
d) Nutritional deficiency:-
In nutrional deficiency there is glossitis(inflammation of tongue) leading to papillary hypertrophy followed by atrophy.
e) Benign migratory glossitis:-
It is an inflamatory condition of the tongue where multiple annular areas of desquamation of papillae appear on the tongue which shift from area to area in few days.
f) Thiamine and riboflavin deficiency:-
Deficiency of these vitamins cause hypertrophied filiform and fungiform papillae.
g) Niacin and iron deficiency:-
In this condition there is atrophy of papillae.Smooth tongue is encountered in iron deficiency.
h) Vitamin A deficiency:-
This causes furrowed tongue.
i) In nutritional megaloblastic anaemia tongue becomes smooth.
j) Folic acid deficiency:-
Here macrocytic megaloblastic anaemia with glossitis is seen.
k) Cyano coblamine deficiency:-
Here glossitis with macrocytic megaloblastic anaemia and peripheral neuropathy is encountered.
l) Scarlet fever;-
In this streptococcal infection there is bright red papillae standing out of a thick white fur ,later the white coat disappear leaving enlarged papillae on the bright red surface and is called strawberry tongue.
6) Ulcers on the tongue:--
a) Apthous ulcer:-
These are round painful ulcers appear in stressed individuals frequently. May be associated with food allergy.Usual sites are tongue,lips,oral mucosa and ect.
b) Herpes simplex:-
It is an acute vesicular eruptions produced by herpes simplex virus.When these vesicles rupture it forms ulcers.
c) Ulcer in cancer:-
Cancerous ulcers are having everted edges with hard base.Bleeding is also seen.Cancer of the tongue is common in tobacco chewers.
d) Syphilitic ulcers:-
Syphilitic fissures are longitudinal in direction.In primary syphilis extra genital chancre is seen on the tongue.In secondary syphilis multiple shallow ulcers are seen on the under surface and sides of the tongue.In tertiary syphilis gumma may be seen on the midline of the dorsum of the tongue.
e) Dental ulcers:-
These ulcers are produced by sharp edges of carious teeth.
The transforming power or alcohol is marvelous, and often appalling. It seems to open a way of entrance into the soul for all classes of foolish, insane or malignant spirits, who, so long as it remains in contact with the brain, are able to hold possession. Men of the kindest nature when sober, act often like fiends when drunk. Crimes and outrages are committed, which shock and shame the perpetrators when the excitement of inebriation has passed away. Referring to this subject, Dr. Henry Munroe says:
"It appears from the experience of Mr. Fletcher, who has paid much attention to the cases of drunkards, from the remarks of Mr. Dunn, in his 'Medical Psychology,' and from observations of my own, that there is some analogy between our physical and psychical natures; for, as the physical part of us, when its power is at a low ebb, becomes susceptible of morbid influences which, in full vigor, would pass over it without effect, so when the psychical (synonymous with the moral ) part of the brain has its healthy function disturbed and deranged by the introduction of a morbid poison like alcohol, the individual so circumstanced sinks in depravity, and "becomes the helpless subject of the forces of evil, "which are powerless against a nature free from the morbid influences of alcohol."
Different persons are affected in different ways by the same poison. Indulgence in alcoholic drinks may act upon one or more of the cerebral organs; and, as its necessary consequence, the manifestations of functional disturbance will follow in such of the mental powers as these organs subserve. If the indulgence be continued, then, either from deranged nutrition or organic lesion, manifestations formerly developed only during a fit of intoxication may become permanent , and terminate in insanity or dypso-mania. M. Flourens first pointed out the fact that certain morbific agents, when introduced into the current of the circulation, tend to act primarily and specially on one nervous centre in preference to that of another, by virtue of some special elective affinity between such morbific agents and certain ganglia. Thus, in the tottering gait of the tipsy man, we see the influence of alcohol upon the functions of the cerebellum in the impairment of its power of co-ordinating the muscles.
Certain writers on diseases of the mind make especial allusion to that form of insanity termed 'dypsomania', in which a person has an unquenchable thirst for alcoholic drinks a tendency as decidedly maniacal as that of homicidal mania ; or the uncontrollable desire to burn, termed pyromania ; or to steal, called kleptomania.
Homicidal mania.
The different tendencies of homicidal mania in different individuals are often only nursed into action when the current of the blood has been poisoned with alcohol. I had a case of a person who, whenever his brain was so excited, told me that he experienced a most uncontrollable desire to kill or injure some one; so much so, that he could at times hardly restrain himself from the action, and was obliged to refrain from all stimulants, lest, in an unlucky moment, he might commit himself. Townley, who murdered the young lady of his affections, for which he was sentenced to be imprisoned in a lunatic asylum for life, poisoned his brain with brandy and soda-water before he committed the rash act. The brandy stimulated into action certain portions of the brain, which acquired such a power as to subjugate his will, and hurry him to the performance of a frightful deed, opposed alike to his better judgment and his ordinary desires.
As to pyromania , some years ago I knew a laboring man in a country village, who, whenever he had had a few glasses of ale at the public-house, would chuckle with delight at the thought of firing certain gentlemen's stacks. Yet, when his brain was free from the poison, a quieter, better-disposed man could not be. Unfortunately, he became addicted to habits of intoxication; and, one night, under alcoholic excitement, fired some stacks belonging to his employers, for which, he was sentenced for fifteen years to a penal settlement, where his brain would never again be alcoholically excited.
Kleptomania.
Next, I will give an example of kleptomania . I knew, many years ago, a very clever, industrious and talented young man, who told me that whenever he had been drinking, he could hardly withstand, the temptation of stealing anything that came in his way; but that these feelings never troubled him at other times. One afternoon, after he had been indulging with his fellow-workmen in drink, his will, unfortunately, was overpowered, and he took from the mansion where he was working some articles of worth, for which he was accused, and afterwards sentenced to a term of imprisonment. When set at liberty he had the good fortune to be placed among some kind-hearted persons, vulgarly called teetotallers ; and, from conscientious motives, signed the PLEDGE, now above twenty years ago. From that time to the present moment he has never experienced the overmastering desire which so often beset him in his drinking days to take that which was not his own. Moreover, no pretext on earth could now entice him to taste of any liquor containing alcohol, feeling that, under its influence, he might again fall its victim. He holds an influential position in the town where he resides.
I have known some ladies of good position in society, who, after a dinner or supper-party, and after having taken sundry glasses of wine, could not withstand the temptation of taking home any little article not their own, when the opportunity offered; and who, in their sober moments, have returned them, as if taken by mistake. We have many instances recorded in our police reports of gentlemen of position, under the influence of drink, committing thefts of the most paltry articles, afterwards returned to the owners by their friends, which can only be accounted for, psychologically, by the fact that the will had been for the time completely overpowered by the subtle influence of alcohol.
Loss of mental clearness.
Alcohol, whether taken in large or small doses, immediately disturbs the natural functions of the mind and body, is now conceded by the most eminent physiologists. Dr. Brinton says: 'Mental acuteness, accuracy of conception, and delicacy of the senses, are all so far opposed by the action of alcohol, as that the maximum efforts of each are incompatible with the ingestion of any moderate quantity of fermented liquid. Indeed, there is scarcely any calling which demands skillful and exact effort of mind and body, or which requires the balanced exercise of many faculties, that does not illustrate this rule. The mathematician, the gambler, the metaphysician, the billiard-player, the author, the artist, the physician, would, if they could analyze their experience aright, generally concur in the statement, that a single glass will often suffice to take , so to speak, the edge off both mind and body , and to reduce their capacity to something below what is relatively their perfection of work.
A train was driven carelessly into one of the principal London stations, running into another train, killing, by the collision, six or seven persons, and injuring many others. From the evidence at the inquest, it appeared that the guard was reckoned sober, only he had had two glasses of ale with a friend at a previous station. Now, reasoning psychologically, these two glasses of ale had probably been instrumental in taking off the edge from his perceptions and prudence, and producing a carelessness or boldness of action which would not have occurred under the cooling, temperate influence of a beverage free from alcohol. Many persons have admitted to me that they were not the same after taking even one glass of ale or wine that they were before, and could not thoroughly trust themselves after they had taken this single glass.
Impairment of memory.
An impairment of the memory is among the early symptoms of alcoholic derangement.
"This," says Dr. Richardson, "extends even to forgetfulness of the commonest things; to names of familiar persons, to dates, to duties of daily life. Strangely, too," he adds, "this failure, like that which indicates, in the aged, the era of second childishness and mere oblivion, does not extend to the things of the past, but is confined to events that are passing. On old memories the mind retains its power; on new ones it requires constant prompting and sustainment."
In this failure of memory nature gives a solemn warning that imminent peril is at hand. Well for the habitual drinker if he heed the warning. Should he not do so, symptoms of a more serious character will, in time, develop themselves, as the brain becomes more and more diseased, ending, it may be, in permanent insanity.
Mental and moral diseases.
Of the mental and moral diseases which too often follow the regular drinking of alcohol, we have painful records in asylum reports, in medical testimony and in our daily observation and experience. These are so full and varied, and thrust so constantly on our attention, that the wonder is that men are not afraid to run the terrible risks involved even in what is called the moderate use of alcoholic beverages.
In 1872, a select committee of the House of Commons, appointed "to consider the best plan for the control and management of habitual drunkards," called upon some of the most eminent medical men in Great Britain to give their testimony in answer to a large number of questions, embracing every topic within the range of inquiry, from the pathology of inebriation to the practical usefulness of prohibitory laws. In this testimony much was said about the effect of alcoholic stimulation on the mental condition and moral character. One physician, Dr. James Crichton Brown, who, in ten years' experience as superintendent of lunatic asylums, has paid special attention to the relations of habitual drunkenness to insanity, having carefully examined five hundred cases, testified that alcohol, taken in excess, produced different forms of mental disease, of which he mentioned four classes: 1. Mania a potu , or alcoholic mania. 2. The monomania of suspicion. 3. Chronic alcoholism, characterized by failure of the memory and power of judgment, with partial paralysis generally ending fatally. 4. Dypsomania, or an irresistible craving for alcoholic stimulants, occuring very frequently, paroxysmally, and with constant liability to periodical exacerbations, when the craving becomes altogether uncontrollable. Of this latter form of disease, he says: "This is invariably associated with a certain impairment of the intellect, and of the affections and the moral powers ."
Dr. Alexander Peddie, a physician of over thirty-seven years' practice in Edinburgh, gave, in his evidence, many remarkable instances of the moral perversions that followed continued drinking.
Relation between insanity and drunkenness.
Dr. John Nugent said that his experience of twenty-six years among lunatics, led him to believe that there is a very close relation between the results of the abuse of alcohol and insanity. The population of Ireland had decreased, he said, two millions in twenty-five years, but there was the same amount of insanity now that there was before. He attributed this, in a great measure, to indulgence in drink.
Dr. Arthur Mitchell, Commissioner of Lunacy for Scotland, testified that the excessive use of alcohol caused a large amount of the lunacy, crime and pauperism of that country. In some men, he said, habitual drinking leads to other diseases than insanity, because the effect is always in the direction of the proclivity, but it is certain that there are many in whom there is a clear proclivity to insanity, who would escape that dreadful consummation but for drinking; excessive drinking in many persons determining the insanity to which they are, at any rate, predisposed . The children of drunkards, he further said, are in a larger proportion idiotic than other children, and in a larger proportion become themselves drunkards; they are also in a larger proportion liable to the ordinary forms of acquired insanity.
Dr. Winslow Forbes believed that in the habitual drunkard the whole nervous structure, and the brain especially, became poisoned by alcohol. All the mental symptoms which you see accompanying ordinary intoxication, he remarks, result from the poisonous effects of alcohol on the brain. It is the brain which is mainly effected. In temporary drunkenness, the brain becomes in an abnormal state of alimentation, and if this habit is persisted in for years, the nervous tissue itself becomes permeated with alcohol, and organic changes take place in the nervous tissues of the brain, producing that frightful and dreadful chronic insanity which we see in lunatic asylums, traceable entirely to habits of intoxication . A large percentage of frightful mental and brain disturbances can, he declared, be traced to the drunkenness of parents.
Dr. D.G. Dodge, late of the New York State Inebriate Asylum, who, with. Dr. Joseph Parrish, gave testimony before the committee of the House of Commons, said, in one of his answers: "With the excessive use of alcohol, functional disorder will invariably appear, and no organ will be more seriously affected, and possibly impaired, than the brain. This is shown in the inebriate by a weakened intellect, a general debility of the mental faculties , a partial or total loss of self-respect, and a departure of the power of self-command; all of which, acting together, place the victim at the mercy of a depraved and morbid appetite, and make him utterly powerless, by his own unaided efforts, to secure his recovery from the disease which is destroying him." And he adds: "I am of opinion that there is a "great similarity between inebriety and insanity.
"I am decidedly of opinion that the former has taken its place in the family of diseases as prominently as its twin-brother insanity; and, in my opinion, the day is not far distant when the pathology of the former will be as fully understood and as successfully treated as the latter, and even more successfully, since it is more within the reach and bounds of human control, which, wisely exercised and scientifically administered, may prevent curable inebriation from verging into possible incurable insanity."
General impairment of the faculties.
Dr. Richardson, speaking of the action of alcohol on the mind, gives the following sad picture of its ravages:
"An analysis of the condition of the mind induced and maintained by the free daily use of alcohol as a drink, reveals a singular order of facts. The manifestation fails altogether to reveal the exaltation of any reasoning power in a useful or satisfactory direction. I have never met with an instance in which such a claim for alcohol has been made. On the contrary, confirmed alcoholics constantly say that for this or that work, requiring thought and attention, it is necessary to forego some of the usual potations in order to have a cool head for hard work.
"On the other side, the experience is overwhelmingly in favor of the observation that the use of "alcohol sells the reasoning powers, "make weak men and women the easy prey of the wicked and strong, and leads men and women who should know better into every grade of misery and vice. If, then, alcohol enfeebles the reason, what part of the mental constitution does it exalt and excite? It excites and exalts those animal, organic, emotional centres of mind which, in the dual nature of man, so often cross and oppose that pure and abstract reasoning nature which lifts man above the lower animals, and rightly exercised, little lower than the angels.
It excites man's worst passions.
Exciting these animal centres, it lets loose all the passions, and gives them more or less of unlicensed dominion over the man. It excites anger, and when it does not lead to this extreme, it keeps the mind fretful, irritable, dissatisfied and captious.... And if I were to take you through all the passions, love, hate, lust, envy, avarice and pride, I should but show you that alcohol ministers to them all; that, paralyzing the reason, it takes from off these passions that fine adjustment of reason, which places man above the lower animals. From the beginning to the end of its influence it subdues reason and sets the passions free. The analogies, physical and mental, are perfect. That which loosens the tension of the vessels which feed the body with due order and precision, and, thereby, lets loose the heart to violent excess and unbridled motion, loosens, also, the reason and lets loose the passion. In both instances, heart and head are, for a time, out of harmony; their balance broken. The man descends closer and closer to the lower animals. From the angels he glides farther and farther away.
A sad and terrible picture.
The destructive effects of alcohol on the human mind present, finally, the saddest picture of its influence. The most aesthetic artist can find no angel here. All is animal, and animal of the worst type. Memory irretrievably lost, words and very elements of speech forgotten or words displaced to have no meaning in them. Rage and anger persistent and mischievous, or remittent and impotent. Fear at every corner of life, distrust on every side, grief merged into blank despair, hopelessness into permanent melancholy. Surely no Pandemonium that ever poet dreamt of could equal that which would exist if all the drunkards of the world were driven into one mortal sphere.
As I have moved among those who are physically stricken with alcohol, and have detected under the various disguises of name the fatal diseases, the pains and penalties it imposes on the body, the picture has been sufficiently cruel. But even that picture pales, as I conjure up, without any stretch of imagination, the devastations which the same agent inflicts on the mind. Forty per cent., the learned Superintendent of Colney Hatch, Dr. Sheppard, tells us, of those who were brought into that asylum in 1876, were so brought because of the direct or indirect effects of alcohol. If the facts of all the asylums were collected with equal care, the same tale would, I fear, be told. What need we further to show the destructive action on the human mind? The Pandemonium of drunkards; the grand transformation scene of that pantomime of drink which commences with, moderation! Let it never more be forgotten by those who love their fellow-men until, through their efforts, it is closed forever."
