The the deposition and eviction of specific histone variants in the damaged area positively (green arrows) deposition and eviction of specific histone variants in the damaged area positively (green arrows) or or negatively (red arrows) contribute to chromatin accessibility. The subsequent restoration of negatively (red arrows) contribute to chromatin accessibility. The subsequent restoration of chromatin chromatin architecture entails the de novo deposition of histone variants (grey arrows). When known, architecture entails the de novo deposition of histone variants (grey arrows). When known, histone histone chaperones and remodelers involved in these transactions are indicated. Note that the distinction chaperones and remodelers involved in these transactions are indicated. Note that the distinction between histone variant roles in chromatin accessibility and restoration is not that strict: some newly deposited histones also increase chromatin accessibility to repair factors and some histone variants that affect chromatin compaction may persist in chromatin thus contributing to chromatin restoration after damage repair. Mechanistically, macroH2A1 splice isoforms regulate chromatin compaction through distinct pathways: macroH2A1. In addition, macroH2A variants promote chromatin compaction via their linker domain [64], which displays structural and functional similarities to histone H1 [66,67]. Given the well established role of linker histones in chromatin compaction [8], it is tempting to speculate that H1 loss from damaged chromatin may contribute to chromatin decompaction and enhanced accessibility to repair factors. Z, macroH2A, and H1 variants, which exert opposing activities on chromatin compaction (Figure 2), likely contribute to a fine spatio-temporal regulation of the chromatin state during the repair response. Newly synthesized H2A and H3 variants indeed get deposited at damage sites and may contribute to the final chromatin organization after repair. Similar to H3 variants, newly synthesized H2A variants including canonical H2A and H2A. However, the mechanisms underlying the restitution of linker histone positioning are still poorly understood. In particular, it is unclear if they imply the re-incorporation of evicted H1 or the deposition of new molecules, and the molecular players involved in such dynamics are still to be characterized. Refining our knowledge of chromatin restoration after genotoxic stress will be essential as the contribution of new histone molecules, even if transient, may have a significant impact on epigenetic states. This not only influences chromatin structure and functions during repair, but may also have long-lasting effects on the chromatin template.

Z variant is not included in this scheme because of conflicting results the recruitment of specific repair factors. X, required for checkpoint activation in late interphase after low doses of radiations [81] and for the maintenance of genome stability activation in late interphase Indeed, mice and mouse cells depleted for H2A. This phosphorylation occurs on an evolutionarily conserved carboxy-terminal serine, in position 139 in mammals, leading to the so-called H2A. Tridimensional chromatin organization recently emerged as a master regulator of H2A. Several models, which may not be mutually exclusive, have been proposed to explain the formation of megabase-sized H2A. X ubiquitylation and subsequent proteasomal degradation, thus stabilizing pre-existing H2A. This antagonism underlines the importance of a tight balance between the two splice isoforms to avoid pathological outcomes. How mechanistically histone variants prime the recruitment of repair factors is still elusive. However, this needs to be coordinated with chromatin relaxation that usually correlates with an active transcriptional state. The regulation of this delicate balance involves histone modifications [5] but also histone variants and their chaperones. These findings underline the importance of the balance between H2A variants for the regulation of transcriptional silencing in the damaged area. MacroH2A has been associated with transcriptional repression in several contexts [13].

As a general rule treatment interventions purchase rocaltrol 0.25mcg online, manicdepressive illness is best managed by a physician who is willing to follow the patient over a long period of time and who is known to the family symptoms nausea dizziness discount 0.25 mcg rocaltrol amex. Although the prognosis for any individual attack is relatively good symptoms yellow eyes order rocaltrol once a day, it is wise to arrange for a plan of action that will be set in operation at the first hint of a recurrence medicine journal buy rocaltrol 0.25mcg free shipping. Tomes have been written about various psychodynamic approaches to psychotherapy and the authors are unable to comment reliably on them treatment 2nd degree burn 0.25 mcg rocaltrol fast delivery. A structured and problem-oriented approach to psychotherapy medications xyzal discount 0.25 mcg rocaltrol with mastercard, utilizing "cognitive-behavioral" and "interpersonal" strategies, has gained considerable popularity since its introduction in the 1970s by Beck. According to Blenkiron, cognitive-behavioral therapy is most effective in patients with mild to moderate (not chronic) depression, generalized anxiety and panic disorder, and obsessive-compulsive and phobic disorders. Essentially, in the short term, the therapist provides the patient with information on the nature of the illness, its common symptoms, and the active interventions that are to be undertaken to alter the specific misperceptions and the dysfunctional behaviors that spring from them. Noteworthy is the opinion of Gabbard that behavioral-cognitive psychotherapy has been shown to be no better or worse than other forms of psychotherapy. Suicide Some 30,000 suicides are recorded annually in the United States, and attempted suicides exceed this number by about 10 times. Suicide is the eighth leading cause of death among adults in the United States and the second leading cause among persons between the ages of 15 and 24 years, figures that emphasize the importance of recognizing depressions that have a high potential for self-destruction. Every physician should, therefore, be familiar with the few clues we possess to identify those patients who intend to end their lives. Some of the questions that may be broached in the interview regarding depression were listed earlier (page 1311). Physicians should also be aware that the majority of suicides are accomplished by taking an overdose of prescribed medications, for which reason caution needs to be exercised in their prescription and administration in depressed patients. Current opinion, summarized by Mann, indicates that suicidal intent represents a special form of depression, or an important variant of it, and that certain individuals are by nature susceptible as a result of biologic factors. In other words, suicide is not simply a cognitive response to extreme stress or despondency. There is no way for the authors to judge this view, but it seems correct and proponents have pointed to particular indices of serotonin function that differ between depressed individuals who attempt suicide and those who do not. It has also been observed that the inception of modern antidepressant medications has not greatly altered the rate of suicide among depressed patients. In manic-depressive disease and endogenous depression, the risk of suicide over the lifetime of the patient is about 15 percent (Guze and Robins). Other series have recorded even higher rates of depression, alcoholism, and other forms of drug abuse (see Andreasen and Black). The message may be in the form of a direct verbal statement of intent, or it may be indirect, such as giving away a treasured possession or revising a will. It is known that successful suicide is three times more common in men than in women and particularly common among men over 40 years of age. Patients with a history of suicide in either mother or father carry a higher risk than those without such a history. Experience has instructed that important deterrents to suicide are devout Catholicism or comparable religious belief (suicide is a sin), concern about the suffering it would cause the family, and fear of death sincerely expressed by the patient. However, no single one of these attributes stands out as entirely predictive of suicide. As a consequence, one is left with clinical judgment and an index of suspicion as the main guides. The only rule of thumb is that all suicidal threats are to be taken seriously and all patients who threaten to kill themselves should be evaluated by a psychiatrist. Some physicians are reluctant to question depressed patients about the presence of suicidal thoughts on the grounds that this might upset them. More likely it is the physician who is upset by this questioning, for surely the mention of suicide will not alarm persons who are determined to end their lives or offend those with no such intention. Should all efforts fail, the only recourse may be commitment to a psychiatric ward. Although an action of this sort is bound to be stressful for all concerned, hard feelings engendered by a short period of enforced confinement vanish in time; but those who mourn the loss of a loved one through a preventable suicide are apt to be unforgiving. Among patients who have been hospitalized because of a preoccupation with suicide, a particular danger attends the phase of recovery from depression, when the physician may be lulled into a false sense of security. In either case, a psychiatrist should assume the responsibility for setting up a program of therapy and arranging for transfer to a psychiatric ward if this is necessary, or for outpatient treatment. For the depressed patient with terminal disease, the authors have taken the personal position of providing comfort by all possible means but not in assisting the patient to commit suicide. This was the opinion expressed 50 years ago in Medical Research: A Mid-Century Survey, sponsored by the American Foundation. Definitions Neurologists and psychiatrists currently accept the idea that schizophrenia comprises a group of closely related disorders characterized by a particular type of disordered thinking, affect, and behavior. The syndrome by which these disorders manifest themselves differ from those of delirium, confusional states, dementia, and depression in ways that will become clear in the following pages. Unfortunately, the diagnosis of schizophrenia depends on the recognition of characteristic psychologic disturbances largely unsupported by physical findings and laboratory data. In other words, any group of patients classified as schizophrenic will to some extent be "contaminated" by patients with diseases that only resemble schizophrenia, whereas variant or incomplete cases of schizophrenia may not have been included. Moreover, there is not full agreement as to whether all the conditions called schizophrenic are the expression of a single disease process. In America, for example, paranoid schizophrenia is usually considered to be a subtype of the common syndrome, whereas in some parts of Europe it is thought to be a separate disease. Historical Background Present views of the disease now called schizophrenia originated with Emil Kraepelin, a Munich psychiatrist, who first clearly separated it from manic-depressive psychosis. He called it dementia praecox (adopting the term introduced earlier by Morel) to refer to a deterioration of mental function at an early age, from a previous level of normalcy. At first, Kraepelin believed that "catatonia" and "hebephrenia," which had previously been described by Kahlbaum and by Hecker, respectively, as well as the paranoid form of schizophrenia, were separate diseases, but later, by 1898, he had concluded that these were all subtypes of a single disease. He emphasized an onset in adolescence or early adult life and a chronic course, often ending in marked deterioration of personality as the defining attributes of all forms of the disease. Early in the twentieth century, the Swiss psychiatrist Eugen Bleuler substituted the term schizophrenia for dementia praecox. This was an improvement insofar as the term dementia was already being used to specify the clinical effects of another category of disease, but unfortunately the new name implied a "split personality" or "split mind. Bleuler also introduced the terms autism ("thinking divorced from reality") as an aspect of the thought disorder. However interesting this formulation proved to be, the psychologic abnormalities are so difficult to define precisely that this arbitrary division has been of only mnemonic value. Meyer, who introduced the "psychobiologic approach" to psychiatry, sought the origins of schizophrenia, as well as other psychiatric syndromes, in the personal and medical history of patients emphasizing particularly their habitual reactions to life events. Freud viewed schizophrenia as a manifestation of a "weak ego" and an inability to use the ego defenses to control anxiety and instinctual forces- the result of a fixation of libido at an early ("narcissistic") stage of psychosexual development. None of these theories has been corroborated, and none ever gained wide acceptance. In 1937, Langfeldt advanced the important concept that schizophrenia consists principally of two different types of psychosis: (1) one that corresponds to the disease considered briefly earlier, i. For the second type, which could be a manifestation of several diseases, Langfeldt proposed the term schizophreniform psychosis. A more contemporary biologic approach to schizophrenia has involved the isolation of its many persistent mental and behavioral features into three clusters: (1) so-called negative symptoms of diminished psychomotor activity (poverty of speech and spontaneous movement, flatness of affect); (2) a "disorganization" syndrome, or thought disorder (fragmentation of ideas, loosening of associations, tangentiality, and inappropriate emotional expression); and (3) reality distortion, comprising hallucinations and delusions or so-called positive symptoms (Liddle; Liddle and Barnes). The separation of behavior into "positive" and "negative" symptoms was believed to be useful in distinguishing among the types of schizophrenia and perhaps to align the mental status with conventional physiologic analysis but this view is an oversimplification (see review by Andreasen). Although there is still disagreement as to whether each of these groups is primary or secondary, positive or negative, they have the value of lending themselves to objective study and correlation with other biologic measures. The incidence of schizophrenia has remained more or less the same over the past several decades. For unknown reasons, the incidence is higher in social classes showing high mobility and disorganization. It has been suggested that this is a secondary result of "downward drift" as a result of deteriorating function caused by the disease to the lowest socioeconomic stratum, where one finds poverty, crowding, limited education, and associated handicaps; and the same data have been used to support the idea that schizophrenia can be caused by such social factors. The fertility of schizophrenics, formerly lowered by institutionalization, is now approaching that of the general population, which will probably result in an increase in the number of cases. Schizophrenic patients occupy about half the beds in mental hospitals- more hospital beds than are allocated to any other single disease-and they constitute 20 to 30 percent of all new admissions to psychiatric hospitals (100,000 to 200,000 new cases per year in the United States). The age of admission to the hospital is between 20 and 40, with a peak between 28 to 34 years. The economic burden created by this disease is enormous- in 1990, the direct and indirect costs in the United States were estimated to be $33 billion (Rupp and Keith). It is unlike the condition that prevails in delirium and other confusional states, dementia, and depression. Some patients with chronic schizophrenia, before the onset of a flagrant psychosis or when in remission, show none of the schneiderian first-rank symptoms and- during brief testing of mental status- might even pass for normal. But on long-term observation they are vague and preoccupied with their own thoughts. They seem unable to think in the abstract, to understand fully figurative statements such as proverbs, or to separate relevant from irrelevant data. There is what has been called a circumstantiality and tangentiality about their remarks. Parts are confused with the whole or are clustered together or condensed in an illogical way. Opposites may be considered as identical, and conceptual relationships are distorted. In an analysis of a problem or a situation, there is a tendency to be overinclusive rather than underinclusive (as happens in dementia). In conversation and in writing, the trend of an argument or thought sequence is often interrupted abruptly, with a resulting disorder of verbal communication. There is over time a general deterioration in functioning, social withdrawal and at times bizarre actions, idleness, self-absorption, and aimlessness. In more severely affected schizophrenic patients, thinking is even more disintegrated. They appear to be totally preoccupied with their inner psychic life (thus the early use of the term autism) and may do no more than utter a series of meaningless phrases or neologisms, or their speech may be reduced to a nonsensical "word salad. At times these patients are talkative and exhibit odd behavior; at other times they are quiet and idle; in the extreme, the patients are mute or assume and maintain imposed postures or remain immobile (catalepsy). With remission, they may remember much of what has happened or they may have only fragmentary memories of events that occurred. The patient may express the thought that his body is somehow separated from his mind, that he does feel like himself, that his body belongs to someone else, or that he is unsure of his own identity or even sex. Thought insertion, wherein it seems to the patient that an idea has been implanted into his mind, or thought withdrawal, wherein an idea has been extracted from his mind by an outside agency, are other parts of this problem. Closely related, and characteristic of schizophrenia, are ideas of being under the control of some external agency or being made to speak or act in ways that are dictated by others, often through the medium of radar, telepathy, or the internet (passivity feelings). Frequently, there are ideas of reference- that the remarks or actions of others are subtly or overtly directed to the patient. Finally, the patient may feel that the world about him is changed or unnatural, or his perception of time may be altered, not in a brief episode like the jamais vu of a temporal lobe seizure, but continuously; this is the phenomenon of derealization. The voices may or may not be recognized; they may belong to one person or two or more persons who converse with the patient or with one another. Instead, they seem to come from within the patient, so that at times they cannot be distinguished from his own feelings and thoughts. Certain somatic hallucinations and delusions may predominate in any one individual. Visual, olfactory, and other types of hallucinations also occur but are much less frequent. The patient believes in the reality of these hallucinations and often weaves them into a delusional system. It should be reiterated here that hallucinations are a feature of a number of neurologic processes but in most, visual hallucinations predominate whereas auditory hallucinations are the hallmark of schizophrenia. Of interest in this regard is "The Report on the Census of Hallucinations" by Sidgwick in 1894 that suggested (as cited by Frith) that almost one in ten ostensibly normal respondents had experienced hallucinations, mostly visual. The illnesses in which hallucinations and delusions are prominent, for example hallucinogenic drug ingestion and the Charles Bonnet syndrome (see pages 220 and 405), have been reviewed by Frith. Of interest has been the belated affirmation of the importance of negative symptoms in schizophrenia. Liddle and Barnes, looking objectively at all aspects of schizophrenic thought and behavior, divided them into four groups: (1) flat affect, diminution in expressive gestures, latency of response, reduced spontaneous movements, apathy, restricted recreational activities, inability to feel intimate or close, and motor retardation. These authors also found an overlap of symptoms from one group of symptoms to another, i. However valid such subdivisions prove to be, they offer a more systematic neurologic approach to schizophrenia and direct attention to the functional anatomy and physiology of particular neuronal systems in the brain (see further on; also Friston et al). The behavior of the schizophrenic who experiences these ideas and feelings is correspondingly altered. Early in the course of the illness, normal activities may be slowed or interrupted. The patient may be idle for long periods- preoccupied with inner ruminations- and may withdraw socially. A panic or frenzy of excitement may lead to an emergency ward visit (a high degree of anxiety occurring for the first time in a young person should always raise the suspicion of a developing schizophrenia); or the patient may become mute and immobile, i. Ultimately a deteriorated and dilapidated state occurs which, in the extreme, results in an unkempt and malnourished state with which the public unfortunately associates schizophrenia. Some individuals of this type roam the streets and live in appalling conditions on the fringes of society where they are subject to the criminal behavior of others. More often one observes agitation and an appropriate display of emotion in response to a threatening hallucination or delusion, although as the illness advances increasing indifference and preoccupation appear, as though the patient had become inured to the abnormal thoughts and feelings. That schizophrenia of all types carries a significant risk of suicide is not generally appreciated.


An even higher rate of benefit was obtained in a prospective series by Illingworth and colleagues (cure of 81 of 83 patients) 7 medications that cause incontinence discount 0.25 mcg rocaltrol fast delivery. The pathophysiology of the spasm is believed to be focal demyelination nerve root compression medicine hunter order 0.25mcg rocaltrol with visa. The demyelinated axon is theorized to activating adjacent nerve fibers by ephaptic transmission ("artificial" synapse of Granit et al) medicine 122 discount 0.25mcg rocaltrol fast delivery. Another possible source of the spasm is spontaneous ectopic excitation arising in injured fibers medicine 801 order 0.25mcg rocaltrol otc. Nielsen and Jannetta have shown that ephaptic transmission disappears after the nerve is decompressed treatment xanax overdose buy cheap rocaltrol 0.25mcg line. Treatment Surgical decompression of a vascular loop treatment mononucleosis order generic rocaltrol on line, which involves exploration of the posterior fossa, carries some small risk. Another complication has been deafness due to injury of the adjacent eighth nerve. Also, there is a modest risk of recurrence of the spasms, usually within 2 years of the operation (Piatt and Wilkins). The authors suggest that patients with idiopathic hemifacial spasm should first be treated medically. Alexander and Moses noted that carbamazepine (Tegretol) in a dosage of 600 to 1200 mg/day controlled the spasm in two thirds of the patients. Some patients cannot tolerate these drugs, have only brief remissions, or fail to respond; they may be treated with botulinum toxin injected into the orbicularis oculi and other facial muscles. The hemifacial spasms are relieved for 4 to 5 months and injections can be repeated without danger. Some patients have been injected repeatedly for more than 5 years without apparent adverse effects. Other Disorders of the Facial Nerve Facial myokymia is a fine rippling activity of all the muscles of one side of the face mentioned above. The fibrillary nature of the involuntary movements and their arrhythmicity tend to distinguish them from the coarser intermittent facial spasms and contracture, tics, tardive dyskinesia, and clonus. Demyelination of the intrapontine part of the facial nerve and possibly supranuclear disinhibition of the facial nucleus have been the postulated mechanisms. A clonic or tonic contraction of one side of the face may be the sole manifestation of a cerebral cortical seizure. Involuntary recurrent spasm of both eyelids (blepharospasm) may occur with almost any form of dystonia but is most frequent in elderly persons as an isolated phenomenon, and there may be varying degrees of spasm of the other facial muscles (see page 93). Relaxant and tranquilizing drugs are of little help in this disorder, but injections of botulinum toxin into the orbicularis oculi muscles give temporary or lasting relief. A few of our patients have been helped (paradoxically) by L-dopa; baclofen, clonazepam, and tetrabenazine in increasing doses may be helpful. In the past, failing these measures, the periorbital muscles were destroyed by injections of doxorubicin or surgical myectomy (Hallett and Daroff). With the advent of botulinum treatment, there is no longer a need to resort to these extreme measures. Rhythmic unilateral myoclonia, akin to palatal myoclonus, may be restricted to facial, lingual, or laryngeal muscles. The Ninth, or Glossopharyngeal, Nerve Anatomic Considerations this nerve arises from the lateral surface of the medulla by a series of small roots that lie just rostral to those of the vagus nerve. The glossopharyngeal, vagus, and spinal accessory nerves leave the skull together through the jugular foramen and are then distributed peripherally. The ninth nerve is mainly sensory, with cell bodies in the inferior, or petrosal, ganglion (the central processes of which end in the nucleus solitarius) and the small superior ganglion (the central fibers of which enter the spinal trigeminal tract and nucleus). Within the nerve are afferent fibers from baroreceptors in the wall of the carotid sinus and from chemoreceptors in the carotid body. The baroreceptors are involved in the regulation of blood pressure, and chemoreceptors are responsible for the ventilatory responses to hypoxia. The somatic efferent fibers of the ninth nerve are derived from the nucleus ambiguus, and the visceral efferent (secretory) fibers, from the inferior salivatory nucleus. These fibers contribute in a limited way to the motor innervation of the striated musculature of the pharynx (mainly of the stylopharyngeus, which elevates the pharynx), the parotid gland, and the glands in the pharyngeal mucosa. It is commonly stated that this nerve mediates sensory impulses from the faucial tonsils, posterior wall of the pharynx, and part of the soft palate as well as taste sensation from the posterior third of the tongue. However, an isolated lesion of the ninth cranial nerve is a rarity, and the effects are not fully known. In one personally observed case of bilateral surgical interruption of the ninth nerves, verified at autopsy, there had been no demonstrable loss of taste or other sensory or motor impairment. This suggests that the tenth nerve may be responsible for these functions, at least in some individuals. The role of the ninth nerve in the reflex control of blood pressure and ventilation has been alluded to earlier but referable clinical manifestations from damage of this cranial nerve are infrequent except perhaps for syncope as noted below. One may occasionally observe a glossopharyngeal palsy in conjunction with vagus and accessory nerve involvement due to a tumor in the posterior fossa or an aneurysm of the vertebral artery. Hoarseness due to vocal cord paralysis, some difficulty in swallowing, deviation of the soft palate to the sound side, anesthesia of the posterior wall of the pharynx, and weakness of the upper trapezius and sternomastoid muscles make up the clinical picture (see Table 47-1, jugular foramen syndrome). On leaving the skull, the ninth, tenth, and eleventh nerves lie adjacent to the internal carotid artery, where they can be damaged by a dissection of that vessel. Glossopharyngeal Neuralgia (see also page 163) this disorder first described by Weisenburg in 1910 resembles trigeminal neuralgia in many respects except that the unilateral stabbing pain is localized to one side of the root of the tongue and throat. Sometimes the pain overlaps the vagal territory beneath the angle of the jaw and external auditory meatus. It may be triggered by coughing, sneezing, swallowing, and pressure on the tragus of the ear. Temporary blocking of the pain by anesthetizing the tonsillar fauces and posterior pharynx with 10% lidocaine spray is diagnostic. Fainting as a manifestation of vagoglossopharyngeal neuralgia is described on page 325. The same drugs that have been found helpful in the treatment of tic douloureux may be used to treat glossopharyngeal neuralgia, but their efficacy has been difficult to judge. Regarding vascular compression of the nerve, Resnick and colleagues have reported the results of microvascular decompression of the ninth nerve in 40 patients; in 32 of these, relief of symptoms was complete and was sustained during an average follow-up of 4 years; 3 patients remained with permanent weakness of structures thought to be innervated by the ninth nerve. If syncope is associated with the pain, it can be expected to cease with abolition of the attacks of pain. Syncope can also occur when the ninth nerve is involved by tumors of the parapharyngeal space; most of these are squamous cell carcinomas and both the ninth and tenth nerves are implicated. Section of rootlets of the ninth nerve has reportedly reduced or abolished the episodes of fainting in these cases. The Tenth, or Vagus, Nerve Anatomic Considerations this nerve has an extensive sensory and motor distribution and important autonomic functions. It has two ganglia: the jugular, which contains the cell bodies of the somatic sensory nerves (innervating the skin in the concha of the ear), and the nodose, which contains the cell bodies of the afferent fibers from the pharynx, larynx, trachea, esophagus, and thoracic and abdominal viscera. The central processes of these two ganglia terminate in relation to the nucleus of the spinal trigeminal tract and the tractus solitarius, respectively. The motor fibers of the vagus are derived from two nuclei in the medulla- the nucleus ambiguus and the dorsal motor nucleus. The former supplies somatic motor fibers to the striated muscles of the larynx, pharynx, and palate; the latter supplies visceral motor fibers to the heart and other thoracic and abdominal organs. Complete interruption of the intracranial portion of one vagus nerve results in a characteristic paralysis. The uvula deviates to the normal side on phonation, but this is an inconstant sign in disease. There is loss of the gag reflex on the affected side and of the curtain movement of the lateral wall of the pharynx, whereby the faucial pillars move medially as the palate rises in saying "ah. There may be a loss of sensation at the external auditory meatus and back of the pinna. If the pharyngeal branches of both vagi are affected, as in diphtheria, the voice has a nasal quality, and regurgitation of liquids through the nose occurs during the act of swallowing. Diseases Affecting the Vagus Complete bilateral paralysis is said to be incompatible with life, and this is probably true if the nuclei are entirely destroyed in the medulla by poliomyelitis or some other disease. However, in the cervical region, both vagi have been blocked with procaine in the treatment of intractable asthma without mishap. Superior cardiac rami Inferior cardiac rami Pulmanary branches Distal Vagus Esophageal plexus Esophageal hiatus of diaphragm Anterior and posterior Vagus nerves Figure 47-4. Note the relationship to the spinal-accessory and glossopharyngeal nerves at the jugular foramen and the long course of the left recurrent laryngeal nerve, which is longer than the right and hooks around the aortic arch [not shown]. Polymyositis and dermatomyositis, which cause hoarseness and dysphagia by direct involvement of laryngeal and pharyngeal muscles, thereby simulate disease of the vagus nerves. A fact of some importance is that the left recurrent laryngeal nerve, because of its long course under the aortic arch, may be damaged as a result of thoracic disease. There is no dysphagia with lesions at this point in the nerve since the branches to the pharynx (but not to the larynx) have already been given off. For this reason, an aneurysm of the aortic arch, an enlarged left atrium, mediastinal lymph nodes from bronchial carcinoma, and a mediastinal or superior sulcus lung tumor are much more frequent causes of an isolated (left) vocal cord palsy than are intracranial diseases. It is estimated that in one-quarter to one-third of all cases of paralysis of the recurrent laryngeal nerve no cause can be established, i. The highest incidence is in the third decade, and males are more susceptible than females. Of the 21 cases reported by Blau and Kapadia, 5 recovered completely and 5 partially within a few months; no other disease appeared in the 8-year period that followed. Palsies of the superior and recurrent laryngeal nerves, occurring as part of isolated vagal neuropathies, have been described by Berry and Blair. A few were bilateral, and again, the majority of the cases were idiopathic and had much the same prognosis as isolated palsies of the recurrent laryngeal nerve. Laryngeal neuralgia is a rare entity, in which paroxysms of pain are localized over the upper portion of the thyroid cartilage or hyoid bone on one or both sides. In the case reported by Brownstone and coworkers it was relieved by carbamazepine. Bannister and Oppenheimer have called attention to defects of phonation and laryngeal stridor as early features of autonomic failure in multiple system atrophy (page 925). We have seen several such patients in whom stridor was a prominent feature of the illness, in one patient for 7 months before other features of the disease became evident. The vagus nerve may be implicated at the meningeal level by tumors and infectious processes and within the medulla by vascular lesions. Herpes zoster may attack this nerve, either alone or together with the ninth nerve as part of a jugular foramen syndrome. The vagus is often affected along with the glossopharyngeal nerve in spontaneous dissection of the carotid artery at the base of the skull. The vagus nerves may Diagnosis When confronted with a case of vocal cord palsy, the physician is advised to determine the site of the lesion. If intramedullary, there are usually ipsilateral cerebellar signs, loss of pain and temperature sensation over the ipsilateral face and contralateral arm and leg, and an ipsilateral Bernard-Horner syndrome (Table 34-3). If the lesion is extramedullary but intracranial, the glossopharyngeal and spinal accessory nerves are frequently involved as well (jugular foramen syndrome, see Table 47-1). If extracranial in the posterior laterocondylar or retroparotid space, there may be a combination of ninth, tenth, eleventh, and twelfth cranial nerve palsies and a Bernard-Horner syndrome. Combinations of these lower cranial nerve palsies, which have a variety of eponymic designations (see Table 47-1), are caused by various tumors, both primary and metastatic, or by chronic inflammations or granulomas involving lymph nodes at the base of the skull. If there is no palatal weakness and no pharyngeal or palatal sensory loss, the lesion is below the origin of the pharyngeal branches, which leave the vagus nerve high in the cervical region. Its fibers arise from the anterior horn cells of the upper four or five cervical segments and enter the skull through the foramen magnum. Intracranially, the accessory nerve travels for a short distance with the part of the tenth nerve that is derived from the caudalmost cells of the nucleus ambiguus; together, the two roots are referred to as the vagal-accessory nerve or cranial root of the accessory nerve. The aberrant vagus fibers then rejoin the main trunk of the vagus, and the fibers derived from the cervical segments of the spinal cord form an "external ramus" and innervate the ipsilateral sternocleidomastoid and trapezius muscles. In patients with torticollis, however, division of the upper cervical motor roots or the spinal accessory nerve has often failed to ablate completely the contraction of the sternocleidomastoid muscle. This suggests a wider innervation of the muscle, perhaps by fibers of apparent vagal origin that join the accessory nerve for passage through the jugular foramen. A complete lesion of the accessory nerve results in weakness of the sternocleidomastoid muscle and upper part of the trapezius (the lower part of the trapezius is innervated by the third and fourth cervical roots through the cervical plexus). Weakness can be demonstrated by asking the patient to shrug his shoulders; the affected side will be found to be weaker, and there will often be evident atrophy of the upper part of the trapezius. With the arms at the sides, the shoulder on the affected side droops and the scapula is slightly winged; the latter defect is accentuated with lateral movement of the arm (with serratus anterior weakness, winging of the scapula is more prominent and occurs on forward elevation of the arm). This muscle can be further tested by having the patient press his head forward against resistance or lift his head from the pillow. Motor system disease, poliomyelitis, syringomyelia, and spinal cord tumors may involve the cells of origin of the spinal accessory nerve. In its intracranial portion, the nerve is usually affected along with the ninth and tenth cranial nerves by herpes zoster or by lesions of the jugular foramen (glomus tumors, neurofibromas, metastatic carcinoma, jugular vein thrombosis). In the posterior triangle of the neck, the eleventh nerve can be damaged during surgical operations and by external compression or injury. It begins with pain in the low lateral neck that subsides in a few days and is followed by weakness and atrophy in the distribution of the nerve. Also, a recurrent form of spontaneous accessory neuropathy has been described (Chalk and Isaacs). About one quarter to one third of eleventh nerve lesions are estimated to be of this idiopathic type; most but not all of the patients recover.
