DROOLING (OR SIALORRHEA) AS AN "ISOLATED" SYMPTOM IN TWO PERSONS, AND ITS TREATMENT WITH PRIMARILY ANTISTRESS DRUG THERAPY. (Updated)

Renato COCCHI, a neurologist and a medical psychologist.

 

 (Other two texts on this topic)

 

Summary.

This report concerns a first history on short-term results, of an antistress drug therapy in two men, one of 37 and the other of 28 years, where the drooling appeared as serious isolate trouble. This symptom was not secondary (or better: tertiary?) to other known illnesses that have it as a collateral phenomenon.

As an aspecific stress response, the sialorrhea occurs in many illnesses, which entirely diverge. It may reduce following antistress drug therapy, as observed in Down persons (Cocchi, 2004b) and as we are seeing in these two cases, which are near surely the first ones so treated.

We suggested that the sialorrhea is creditable to the fact that the stress is able determine a GABAergic-glutamergic hypothalamic unbalance, with overfunction of the hypothalamic pathways which control the vagal nuclei, mainly the nucleus ambiguous, ( It gives origin even to the glossopharyngeal nerve), which became so overstimulated.

After I reported on the sialorrhea in Downs, either for epidemiology and the long term results of an antistress drug therapy, although not planned for treating this symptom (Cocchi, 2004a; Cocchi, 2004b), two men came to my observation, suffering from this pathology, as prevailing symptom, if not exclusive. Drooling much disturbed both them (see, later on, emails sent to contact me).

I did not give them any certainty, because I never faced specifically this problem. The positive results, in Downs, were something of more, after several months of an antistress individualized drug therapy, which produced such favourable results. About both these cases, I wanted to report on this article.

Short summary the actual and personal knowledges on the sialorrhea.

I quote back here, what I wrote previously as an introduction to my first investigation.

"Sialorrhea, or excess of drooling, is a symptom in many persons with many different illnesses such as: Cerebral palsy; Palsies of the cranial nerves VII, IX, and XII; Autism and PDD; Mental retardation; Stroke; Amyotrophic lateral sclerosis; Down syndrome; Motor neuron disease;Parkinsonism; Congenital suprabulbar palsy; Head trauma; Encephalitis; Heavy metal intoxication; Graves' disease (a hypertiroidism); Rabies; Extra-esophageal reflux disease; Nasal and/or pharyngeal obstruction; Major surgical resection of structures in the oral cavity/pharynx/hypopharynx.

It is a symptom thant can also be induced by drugs, during antipsychotic therapies.

Drooling also impairs socially the sufferers from it and isolation is unfortunately frequent because saliva soils furniture, carpets, toys, and the clothing of peers, siblings, parents, relatives and caregivers.

The saliva production comes out from both the major and minor salivary glands, the secretory action of which is mainly under the control of the parasympathetic nervous system. Excessive drooling is a condition that can induce heavy hygienic and psychosocial problems"(Cocchi, 2004a).

Although the problem of excess salivation with drooling in Down syndrome persons, was a well-known datum, there was not, as for me (I searched on Google, and on Medline since 1960 with key words: sialorrhea, oversalivation, drooling, Down syndrome) any epidemiological investigation on this symptom. Still now, that I did (Cocchi, 2004a) is the only one on this special population.

The oversalivation with saliva loss is an aspecific symptom that we can find in subjects with full different illnesses (Cocchi, 2004a).

Although we can find it in Down children in about the 20% of them (Cocchi, 2004a), the sialorrhea cannot be then a symptom that directly depends from the chromosomal anomaly 21, otherwise all Downs should have had it.

Furthermore, according to every physicians' experience, we can observe even in other chromosomal or genetic anomalies (see later on).

Too inclining to disappear in the Down, with the age growing, it is of common evidence that some elderly persons start to lose saliva by day, without having done it never in past.

In preceding research I thought as possible that the sialorrhea was a symptom of internal metabolic stress, with a district parasympathetic excess activation coming from the brain (Cocchi, 2004a).

In my second investigation (Cocchi, 2004b) I confirmed this first idea, even if the link appeared more complex.

The primarily antistress drug therapy I prescribed, too having significantly driven the disappearance of the symptom in over than 96% of so treated individuals, did not work in two cases.

This exception remembers, by analogy, what happens in nighttime enuresis, which in nearly all cases disappears with the puberty, but such a result is not always so favourable. Being a nighttime bedwetting person, he had an unfit classification to the military service, in Italy. So, because otherwise this enuretic young man should have become the laughingstock of all the fellow soldiers, with many burden psychological-relational outcomes.

Both the sialorrhea and the daily enuresis can reappear, or first appear, in elderly persons.

For a drug therapy, other physicians tried the way of the anticholinergic drugs, owing to the parasympathetic prevalence of the symptom, having the parasympathetic system, the acetylcholine, as the main neurotransmitter.

The more studied drugs were the benztropine, the saltropine, the glycopyrrolate, and the scopolamine. Their effectiveness on the drooling is much variable and unpredictable, and they not overcome 45% of the so treated subjects. The anticholinergic drugs act by inhibiting the saliva secretion through a reversible blockade of the cholinergic receptors which control it. There are reports of side effects like a dry mouth, dilation of the pupils, blurred vision, retention of urine, constipation, dizziness and disorientation, with need of stopping the drug therapy (Ieung and Kao, 1999).

As for I know, no literature on the relationships between sialorrhea and stress is available, if not for the fact that sialorrhea elicits a share of secondary stress of psychologicaland social type. The antistress therapy set up here, was not specifically addressed to the sialorrhea. It gets its base, as it was for the Downs, on what reported in Cocchi, 1993, and, generally, on theoretical bases explicated in Cocchi, 2003.

Besides on the sialorrhea in the Down syndrome, the antistress drug therapy acted favourably on the same disturb in other illnesses.

It occurred that in cases such as the Cri-du-chat syndrome (Cocchi, 2001), syndrome of Aicardi-Goutieres (Cocchi, 2002), partial trisomy of the chromosome 22 (Cocchi, 2003 ), GM1 gangliosidosis (Cocchi, 2003 ), on a mental retardation with microgiry, without any genetic base found (Cocchi, 2002), and on a typical form of autism (Cocchi, 2005).

The sialorrhea could be creditable to the fact that the stress can determine gabaergic-glutamergic hypothalamic unbalance. Sop, it elicits an overfunction of the hypothalamic control pathways on the vagal nuclei, mainly on the ambiguous nucleus (as a common origin even of the glossopharyngeal nerve), which becomes overstimulated. An antistress drug therapy seemed, at least to a large extent, able to bring this mechanism to a better operation, in Downs ( Cocchi, 2004b.)

 

Two case histories.

Patient one, by email: "... My name is...., I read on internet your study about sialorrhea and I am writing you because I am suffering from acute sialorrhea since about 12 years.

I am 37, a normal person and I have a normal life. Last year I had the diagnosis of the coeliac disease, and now I am in a diet for it. Another trouble of mine is the nocturia.

As for the drooling, last years it did worse so much till it prevents me to speak and then it is conditioning me in the social relationships.

I searched consultations by all the possible experts: a neurologist, an otolaryngologist, a gastroenterologist, a maxillofacial physician and an immunologist.

I acted all the prescribed analyses but they were all normal.

The neurologist tried to give me some drugs that would have provoked a dry mouth as a side-effect ( alprazolam, amitriptyline [The brand names of these two drugs were transcribed by that of their basic substances. RC], But I did not reach any result.

Since currently this trouble is so serious that literally prevents me to speak to the people I am looking in their face, I took the drastic decision to irradiate my salivary glands.

The chief physician of the special department, the Doctor ...., of the regional hospital of.... (the town where I live) during the last consultation told me that it can be done. Nevertheless I need to be aware that this intervention has the risk that in the future I could develop a cancer in that body district. I am willing equally to do this treatment.

Here I kindly to ask you, before undergoing X-ray treatment if she knows an alternative treatment or the possible causes of this problem.

I thank you infinitely as for the attention I get from you and for your precious time you will spend to answer me."

The second ten days of June 2005, the first consultation. He is man of 37 years, married, who works as a selling agent.

He has continuous drooling, but not during the night. This trouble appeared 12 years ago, with all the implications and the consequences described in his email searching for a first contact.

Moreover, because his job needs a continuous verbal in touch with the single interlocutor. Any of the many consulted experts found the starting point, and if the sialorrhea were a secondary symptom of a well-known disease. Equally any could set up some advantageous therapy.

I noticed him that I never treated this symptom as such, and what I obtained in Downs was a collateral result. Therefore I know that it is an aspecific symptom and it relates to stress reaction, but I don't know times of response to a possible antistress therapy.

Stress symptoms: He suffers from heat, has a sweet tooth, mainly for the sweet things with the milk cream, but had normal liking for the meat broth. He says is having a coeliac disease [??]. Now, he can stand the light, the noise and the confusion. Fainting feelings do not occur. His hair is dry. He has emotional axillary perspiration. Nocturia runs at least twice in every night.

During the sleep he inclines to have much movement. In certain days he has dyslalias. He doesn't remember to have yawn excess. Rarely he suffers from any headache. There is a tendency to dream disastrous situations, but not always he is waking up.

Possible troubles of half-brain dominance: He admits possible intrusive thought. His concentration has now some difficulty. He is not an undecided person. Perhaps he counts objects without any reason.

Depressive symptoms: To the test "Which is the opposite of the colour Red? he answered Black, but denies of being depressed. As for his diet, he does not need tp look for milk or dairy. In the afternoon, he is more activated. He denies being a wine drinker or of other alcoholic drinks. He doesn't search an intercourse for falling asleep.

Other: At school, till about his 12 years, he was very hyperactive and even now he is quite so. In his first year of life hr cried much and slept a few.

Test therapy (daily doses, by the oral via): Glutamine 125mg; Amantadine 50mg; Pyridoxine 75mg; Nortriptyline 10mg; Carbamazepine 100mg; Oxazepam 7.5mg.

 

First 10 days of September 2005, the first checkup after 84 therapy days. An EEG examination was reported as normal.

He is doing better with less drooling, and he thinks that when at the beginning his sialorrhea was equal to 100, now he evaluates it as 70 (He improved of 30%).

The effect of the therapy works till 5-6 PM. If he is under stress, he restarts drooling in advance. His sleep is not as first and perhaps he sleeps a little better, and he has no drowsiness in the morning.

Perhaps there are fewre bad dreams. During sleep, he is moving as he did previously. His head is not more clear from intrusive thoughts, perhaps he not has them [A debatable assertion, because the concentration trouble leads to presume the opposite. R.C.]. The memory difficulties did not improve. He did not observe any variation on the possible depressed mood. The intake of sweet things did not change. In the afternoon is always more active. Axillary oversweating is as first. His work runs as usual. Now, he uses dressing with more vivacious colours. Dyslalias are not diminished. Perhaps he has more headaches, of a diffused type.

Therapeutic variation (daily doses, by the oral via): Carbamazepine 200mg; oxazepam 15mg.

 

Ten third days of January 2006: The second checkup after six months of drug therapy. According to him, the excessive salivation diminished of 30-40%. He doesn't do more soil dreams. In his work is more uninhibited, but he has always needed to lead one hand before his mouth. He has still problems of fluctuating intrusive thoughts and of concentration lacking. Lately his sleep is more troubled, and he has some wake up again, with two nocturia episodes. The headache unchanged. Still dyslalias occur, as the preceding checkup. The axillary oversweating did not stop. Hyperactivity is always the same. The quality of his work improved.

Therapeutic variation (daily doses, by the oral via) hanging nortriptyline and 100mg carbamazepine. I prescribed amitriptyline 10mg to and valpromide 300mg.

 

Patient 2, by email: .... I am writing him from.... I have 28 years and about since three the quality of my life generally much reduced or better my life became a disaster. It happened so, because of this damned sialorrhea, which unintentionally jumps always out of me in any environment and with all people, except my parents.

I am straight losing my job. ... In a year I consulted practically all medical experts, as psychiatrists, psychologists, homeopaths, neurologists and otolaryngologists. I have spent a lot of money, and since about one month I am assuming benzodiazepines and anticholinergic drugs, but this problem reappears regularly in the evening. I feel notable uneasiness and indescribable difficulty in the interpersonal relationships. ...

 

Third ten days of June 2005, the first consultation. A man, of 28 years, single. He is working in a shoe's factory and weighs 80kg, in spite of an active sporting life.

Since three years he has sialorrhea, not controllable. It appears as an evident issue of saliva dripping directed towards the persons who are near him. This symptom does not occur in presence of his parents or of close relatives, while this happens with extraneous or unknown persons, or even friends. The excess saliva production doesn't own different intensity between morning and afternoon. He doesn't lose saliva when sleeping, and he thinks that this disturbs has an emotional base.

Stress symptoms: He suffers from heat. There is not an increased food intake of sweet things, meat broth, milk and dairy. Currently he doesn't sleep well and he wake once in every night. Some time he spoke during the sleep, while he never had nighttime muscular cramps.

He doesn't know if he has nighttime bruxism, but he realized his dental shut during the day. No intolerance to the light, to the noise, or to the confusion occur. At the morning, he uses the alarm clock to wake up, and often he feels tired, as if he has never had forces. He is hungry at once, and inclines to eat much.

When he becomes anger, usually doesn't manifest it, but there are moments where he needs say blasphemy, or swearwords, apparently for no reason. His hair is fat. He suffers from emotional hands' oversweating, has frequent colic and diarrheas. The redness of the eyes is rare for no reason. Mediastinal oppression does not happen, but in past he had the lump in the throat. Moreover, he is hungry of air, has disbandment and fainting feelings.

Problems of half-brain dominance: To the test "Which the opposite of the colour Red," he answers "Green": He was a Contrary Mary. He did not end the studies of the high school, because he had concentration failures. In past, he had intrusive thinking, but now it is less frequent. Suddenly he has bad thoughts against persons otherwise beloved. Usually he does bad dreams, and he has also a negative vision of the world.

Depressive elements: In his father's family, there was a predisposition to depression. As a young boy he was a jolly fellow. Any headache doesn't occur, but his head is sometime dull. Often tachycardia appears, and some panic attack too. Suicide ideas came out. Now he is taking a drug therapy with perphenazine, orphenadrine and paroxetine, which give him problems of precocious ejaculation, and even erection troubles. The excess of saliva induced him secondary psychological troubles (see email of first contact).

Other: In past he did irregular use of cannabis indica and of 3,4-metilen-dioxi-metamphetamine (MDMA), a derivative from the methamphetamine with the popular name of Extasy. He played European foot-ball, with good technique.

Risk factors in his mother's pregnancy and during delivery and their exits: Not abortion threats were reported. He is a person born to term, with prolonged, delivery with birthweight of 3250 grams. He had not had cyanosis, neither pathological jaundice, nor respiratory distress, but 24 hours of coma in the first week of life. In the same year he had a new coma of six months. Gastroenterites occurred to the first year life, because he doesn't bear his mother's milk. He was not a hyperkinetic child.

Test therapy (daily doses, by the oral via): 125mg glutamine; pyridoxine 75mg; carbamazepine 100mg; diazepam 2mg; paroxetine 10mg.

 

First 10 days of August 2005, the first checkup after 35 days of drug therapy.

As for the excess of saliva, he thinks that there is quantitative diminution of the expelled liquid from the mouth.

His general well-being, according to him, did not change. He sleeps a little better, does not have any more wake ups during the night, no more bad dreams, but at morning he feels more tired [??]. He does labour to get up. Abdominal tension did not decrease. His head is dazed, as first. The dental shut diminished. He eats much, as before this therapy. Less colic and diarrheas and less burning of the eyes occur.

The irritability level, with blasphemy and swearwords periods, did not get any modification. The disbandment feelings remained, but he missed those of fainting. Tachycardia is still current, but no more air hunger. Panic attacks reduced. His hair is fat as first and the hand oversweating did not diminish. After six days of drug therapy his troubles of erection and precocious ejaculation stopped.

Therapeutic variation (daily doses, by the oral via): Hanging the paroxetine. I prescribed amitriptyline + perphenazine 20mg + 4mg; Carbamazepine 200mg; Glutamine 250mg; Diazepam 4mg.

Therapeutic variation (daily doses, by the oral via): Hanging the paroxetine. I prescribed amitriptyline + perphenazine 20mg + 4mg; Carbamazepine 200mg; Glutamine 250mg; Diazepam 4mg.

 

Second ten days of October 2005, the second checkup, after 110 days of drug therapy. He is doing better: The sialorrhea, judged as 100 at the beginning of the therapy, now has 65 as his evaluation. There is no difference between morning and afternoon. Being asked about it, he says that nobody observed this positive result, then he admits that his girlfriend and some workmates noted it.

The relationship with his job improved, where he shows more personality and more grit. The intrusive thinking diminished, and it happened so as for the emergency of bad thoughts against otherwise beloved persons. The excessive feeding did not reduce. Now he is 88kg, and he is much worried about it.

He says that he gets up as tired as first. His hairs are falling, for seborrheic dermatitis. There is still the need to howl and curse. Suicide ideas did not miss. He sleeps well, and has more dreams, with more vivid dreams. Disbandment feelings still occur, but less tachycardia. Now he is less depressed, and he attributes this fact to the reduction of the sialorrhea, and then of the related secondary depression. The dental shut is returned as first, mainly towards the evening. Not more burning of the eyes happened. The panic attacks reappeared. Colic and diarrheas subsequently reduced. Now he does not drink coffee after lunch or dinner, because it has a laxative effect.

Therapeutic variation (daily doses, by oral via): Hanging amitriptyline + perphenazine. I prescribed: Glutamine 125mg; Pyridoxine 150mg; Chlomipramine 10mg; Nortriptyline 10mg; Carbamazepine 300mg.

 

The second ten days of February 2006, the third checkup. As for him, he is worse. No more drooling occurs, but neither less. He says the sialorrhea is now 65% of what rated at the beginning and affirms that he has more labour when speaking with the others, as if was at the preceding checkup.

With the chlomipramine he feels more stimulated, more uninhibited. He feels that, internally, he would react when someone offends him, but he maintains his control.

With the persons with whom he does not has drooling, he is more in touch, but not with the persons in presence of them he loses his saliva.

In his working place, he is going slightly better, and has lesser drooling. In this time he feels less of the judgment of the others, or of what he thinks that the others could think about him. He would like to do better, even with her friends, with whom he has still sialorrhea. He feels himself not entirely accepted since he started to salivate in excess.

His sexual activity is now normal. He has loosened 4kg, since the preceding checkup and now he is weighing 84kg. The fall of his hair reduced, but he has more itch in his head. The capillary sebum increased. His need to howl or to curse did not change. He sleeps well, dreams much, but does misfortune dreams. The feelings of disbandment diminished, while the tachycardia did mot change. He thinks to be depressed as first [In facts, he smiles much more, a datum confirmed even by his girlfriend who attended his consultation. RC].

The dental shut increased, while oversweating of his hands diminished, or nearly missed. Burning of his eyes lowered. The panic attacks are less intense, but colic and diarrheas were more frequent. His bowel stimulation that follows the coffee drinking (even decaffeinated!) after the lunch, decreased.

Therapeutic variation (daily doses, by the oral via): Carbamazepine 100mg; valpromide 300mg; diazepam 6mg.

 

Second ten days of May 2006, the fourth control. He stopped to take the valpromide at the end of April, because, he thought, it doesn't give any results. He is growing fat still. Now, he says that the drooling is unchanged. Now he has the habit of scraping off and this gives him bother to the throat.

In the working place he is doing better [That means less sialorrhea. RC], while when he meets his friends the drooling is not reduced. Currently, he feels more the problem of his difficulty to talk, than that of the sialorrhea [???].

Therapeutic variation (daily doses, by the oral via): Hanging the valpromide; I prescribed amantadine 100mg; S-adenosil-l-methionine 200mg.

 

Discussion.

The initial histories of both these patients need, to be understood, some premises. In spite of my experience with antistress drugs in Down persons, and in other subjects, the positive results on the sialorrhea were always a side effect of those therapies.

When someone asked me a specific action on the sialorrhea, which appeared as an isolate symptom and not a secondary one to other known illnesses, I clarified to both patients that I have never treated this symptom as such. For which I did not know if it had any link to the stress, as I thought. In such a case I had an idea about which drugs I could choose, according to individual responses to stress. Moreover I did not know which doses I would have to use, and the presumable times of positive answering. The reference stress symptoms could be detected. For the doses, I would have held precautionary behaviour, and the answering times were full to discover.

The situation of both patients heartfelt as desperate era (and, in one of them, the intention to have his salivary glands radiated says it enough, about it),

for which both agree to act as guinea-pigs.

How I was expecting, I found stress symptoms in abundance, even if differently in each patient. In both these cases the sialorrhea would be as secondary in the stress condition, and what found again in many different illnesses, therefore it would be as tertiary, according the sequence: --> illness ---> stress reactions --> sialorrhea. The fact that every illness elicits even stress symptoms is one assumption of this site (see the guidelines in <www.stress-cocchi.net/index.htm). The difference of the stress symptoms, drew to a different choice of the drugs for the test therapy, set up according to the presence or absence of some of these symptoms. I first prescribed always modest doses, but in spite of it, some results can already be observed at the first checkup. Even if the checkups occurred in different times, by telephone information, in both patients, the times of improvement were between 35 and about 50 days.

Both patients had some depression, which, in the second patient, it was not only secondary to the psychological troubles induced by the sialorrhea.

As for the resolution times of the trouble, they all are still to discover. Even at the moment of the possible disappearance of the trouble, we will not know still we acted a substituting therapy, like that for the essential hypertension, as to understand, or a curative therapy.

 

Conclusions.

This is the first report on short-term results, of an antistress drug therapy in two men, one of 37 and one of 28 years, where the sialorrhea appeared as serious isolate trouble, and not secondary to other known illnesses where we can find it.

As an aspecific stress response, the sialorrhea occurs in many illnesses, which entirely diverge. It may reduce following antistress drug therapy, as observed in Down persons (Cocchi, 2004b) and as we are seeing in these two cases, which are near surely the first ones so treated.

We suggested that the sialorrhea be creditable to the fact that the stress is able determine a GABAergic-glutamergic hypothalamic unbalance. It leads so to overfunction of the hypothalamic pathways, which control the vagal nuclei, mainly the nucleus ambiguous, (it gives origin even to the glossopharyngeal nerve), which became so overstimulated.
