Thirty induced pain cries from the same number of infants with infectious or congenital disorders of the larynx (infectious laryngitis, laryngomalacia, paresis of the recurrent nerve and subglottic stricture) have been analyzed by means of sound spectrography. For each cry 21 phonetic features have been evaluated. This cry material was then compared with 120 pain cries from healthy infants. In the pathological group a significant increase could be noted in the occurrence of the following cry attributes: second pause, abnormal melody types (rising, falling-rising, flat and no melody types), instability of the fundamental frequency, bi-phonation, vibrato, half-voiced voice quality, noise concentration, and inspiratory stridor. Furthermore, a significant decrease could be noticed in the occurrence of voiceless cries, falling and rising-falling melody types, and glottal roll. These findings show that such spectrographic features as very high maximum and minimum pitch, bi-phonation, gliding, and abnormal melody type occur more often in cries of infants with central nervous system involvement. Moreover, such parameters as instability of the fundamental frequency and noise concentration as indicators of neurologic disorders need further consideration. Except features of inspiratory stridor, this study revealed no really clear parameters typical of peripheral diseases of the vocal tract.

Upper airway obstruction resulting from a paratracheal abscess developed insidiously and led to the death of a 43-year-old woman with multiple sclerosis. Repeated nasogastric intubation, required by an exacerbation of bulbar symptoms, may have initiated this unusual infection. Corticotropin and corticosteroid therapy may have impaired immunologic competence and masked fever and other symptoms of inflammation. Hoarseness and inspiratory stridor should not be attributed to laryngeal paresis in patients with multiple sclerosis unless other causes of airway obstruction have been excluded by appropriate diagnostic studies.

Twenty induced pain cries from the same number of infants with laryngeal disorders (infectious laryngitis, laryngomalacia, recurrens paresis and subglottic stricture) have been analyzed by means of sound spectrography. For each cry 21 phonetical cry features have been evaluated. This cry material was then compared with 120 pain cries from healthy infants. In the pathological group a significant increase could be noted in the occurrence of the following cry attributes: second pause, abnormal melody types, instability of the fundamental frequency, biphonation, vibrato, half-voiced voice quality, and inspiratory stridor. Furthermore, a significant decrease could be noticed in the occurrence of voiceless voice quality and glottal roll. For the other cry parameters no significant differences have been observed. In the light of these findings, the neuropathognomic significance, which has been up to now attached to such spectrographic features as very high maximum pitch, biphonation, gliding, and abnormal melody type, should not be taken too strictly. Moreover, one may conclude that the actual state of cry spectrography does not permit us to regard such parameters as instability of the fundamental frequency and noise concentration as indicators of neurologic disorders. On the other hand, the features inspiratory stridor, vibrato and tonal pit seem, to be to a certain extent typical of peripheral diseases of the vocal tract.

Shy-Drager syndrome consists of progressive autonomic nervous system failure with Parkinson's disease-like symptoms and orthostatic hypotension. It can also result in airway compromise from bilateral vocal cord paralysis. Fewer than 30 cases of severe bilateral vocal cord paresis or paralysis associated with the Shy-Drager syndrome have been reported in the English literature. We present a case of a 72-year-old man who had a 2-year history of orthostatic hypotension, neurogenic bladder, impotence, anhydrosis, and extremity weakness and paresthesias. Hoarseness and dyspnea with stridor developed as a result of bilateral vocal cord paralysis in the median position and required an emergency tracheotomy. This combination of symptoms resulted in the diagnosis of Shy-Drager syndrome. We present the case along with literature review of bilateral vocal cord paralysis with the Shy-Drager syndrome.

The lower cranial nerves (CN. IX-XII) are responsible for the nerve supply of the pharyngolaryngeal region. Loss of innervation is manifested by dysphagia, aspiration, altered speech production, dyspnea and/or stridor, and visible loss of movement. In general electrophysiological testing should be applied in every kind of paresis. Beside standard equipment for electromyography limited special equipment is necessary. Examination under local anaesthesia is possible and can serve as a basis for therapeutic consequences. In this article general aspects as seen from an oto-rhino-laryngological standpoint are presented.

Myotonic dystrophy type 1 (DM1) is the most common inherited muscle disorder and may present in numerous ways due to characteristic multisystem involvement. We report a 47-year-old man who presented with an 8-year history of slowly progressive dyspnea and episodic stridor. The laryngeal paresis was documented with videostroboscopy and laryngeal electromyography, and treated with tracheostomy and antimyotonia agents.

This article deals with the neurological basis of brainstem-related symptoms in disabled children. Synaptic interactions of respiratory and swallowing centers, which are briefly reviewed in this study, highlight the significance of the nucleus of solitary tract (NTS) in the stereotyped motor events. Coordination mechanisms between these two central pattern generators are also studied with a focus on the inhibitory action of decrementing expiratory neurons that terminate the inspiratory activity and become activated during swallowing. Dorsal brainstem lesions in hypoxic-ischemic encephalopathy (HIE) affect the area including NTS, and result in symptoms of apneusis, facial nerve paresis, dysphagia, gastroesophageal reflux, and laryngeal stridor. Leigh syndrome patients with similar distributions of medullary lesions show increased sighs, post-sigh apnea, hiccups, and vomiting in addition to the symptoms of HIE, suggesting pathologically augmented vagal reflex pathways. The present article also discusses the pathophysiology of laryngeal dystonia in xeroderma pigmentosum group A, self-mutilation in Lesch-Nyhan syndrome, and sudden unexpected death in Fukuyama congenital muscular dystrophy. Close observation and logical assessment of brainstem dysfunction symptoms should be encouraged in order to achieve better understanding and management of these symptoms in disabled children.

Neuronal vacuolation and spinocerebellar degeneration is a rare, presumably inherited condition that is reported only in Rottweilers and in crossbred dogs with known or potential Rottweiler heritage. Gross and histopathologic findings include laryngeal muscle atrophy, neuronal vacuolation, and a combined central and peripheral axonopathy. Two 6-month-old Boxer puppies from the same litter were referred for evaluation of progressive pelvic limb paresis and ataxia, upper airway stridor, and visual deficits. Examination of each dog suggested a combined myelopathy and peripheral neuropathy, as well as congenital ocular disease. Gross lesions were limited to atrophy of the intrinsic laryngeal muscles. Histopathologically, there was diffuse loss of axons and myelin in the dorsolateral and ventral funiculi throughout the spinal cord and extending into the caudal aspect of the brain stem. Vacuolation of scattered neuronal cell bodies was present in the spinal cord and selected brain stem nuclei. Multifocal axonal degeneration and demyelination was observed in the recurrent laryngeal nerve, sciatic nerve, and brachial plexus and was most severe in the recurrent laryngeal nerve. Ocular abnormalities included microphthalmia, cataracts, and retinal dysplasia. The findings in these Boxer dogs, unrelated to the Rottweiler breed, are analogous to the syndrome of neuronal vacuolation and spinocerebellar degeneration reported in Rottweilers.

We describe 4 patients with amyotrophic lateral sclerosis (ALS) and glottic narrowing due to vocal cord dysfunction, and review the literature found using the following search terms: amyotrophic lateral sclerosis, motor neuron disease, stridor, laryngospasm, vocal cord abductor paresis, and hoarseness. Neurological literature rarely reports vocal cord dysfunction in ALS, in contrast to otolaryngology literature (4%-30% of patients with ALS). Both infranuclear and supranuclear mechanisms may play a role. Vocal cord dysfunction can occur at any stage of disease and may account for sudden death in ALS. Treatment of severe cases includes acute airway management and tracheotomy.
