The control mechanisms of respiration as a vital function are complex: voluntary - cortical, and involuntary - metabolic, neural, emotional and endocrine. Hormones and hypothalamic neuropeptides (that act as neurotrasmitters and neuromodulators in the central nervous system) play a role in the regulation of respiration and in bronchopulmonary morphology. This article presents respiratory manifestations in adult endocrine diseases that evolve with hormone deficit or hypersecretion. In hyperthyroidism, patients develop ventilation disorders, obstructive and central sleep apnea, and pleural collection...

A case of a 55-year-old woman with iatrogenic vocal cord trauma and sleep-related symptoms is reported. In particular, this case highlights sleep-disordered breathing as a delayed complication after iatrogenic vocal cord trauma. The patient developed acute stridor from a contralateral vocal cord hematoma following vocal fold injection for right vocal cord paralysis. Acute respiratory symptoms resolved with oxygen, steroids, and nebulized therapy, but nocturnal symptoms persisted and polysomnography revealed sleep-related hypoventilation and mild obstructive sleep apnea...

BACKGROUND: Nocturnal stridor and respiratory abnormalities are important features of multiple system atrophy (MSA) with relevance to patient survival, and they are detected and evaluated mainly through video-polysomnography (video-PSG). Diurnal laryngoscopy seems to yield abnormal findings only in the presence of significant vocal cord (VC) dysfunction. AIM: To assess whether specific electrophysiological patterns of diurnal EMG of VC muscles may indicate nocturnal stridor or respiratory dysfunctions in MSA patients...

OBJECTIVE: Children with Down syndrome have a higher incidence of upper airway obstruction and laryngomalacia. We sought to determine outcomes of supraglottoplasty in this patient population. METHODS: A retrospective chart review was performed from January 2000 through January 2014. Children (n = 18) at our institution with the diagnosis of Down syndrome who underwent supraglottoplasty were included. We reviewed patient characteristics, preoperative findings, and surgical outcomes (stridor, feeding problems, respiratory distress, weight, sleep apnea, and tracheostomy or feeding tube dependence)...

INTRODUCTION AND OBJECTIVES: Laryngomalacia (LM) is the most common cause of congenital stridor. Tradition holds that the majority of patients resolve spontaneously by 12-18 months of age. The objective of this study was to systematically review the literature on the spontaneous resolution of LM and/or its presenting symptoms, in otherwise healthy infants. METHODS: Data sources included Medline/PubMed, EMBASE, Scopus, CINAHL, Proquest, Cochrane database, Cochrane Methodology Register, Web of Science Conference Proceedings Citation Index, and ACP Journal Club...

Vagal nerve stimulators (VNS) are surgically implantable medical devices which are approved by the food and drug administration (FDA) for treatment of medically refractory epilepsy in children. Two children with seizures disorders presented to the pediatric otolaryngology clinic with complaints of stridor and sleep apnea following implantation of VNS devices. Both children were evaluated with flexible laryngoscopy, direct laryngoscopy and bronchoscopy. The children were noted to have contraction of their vocal folds and supraglottis and the settings of their VNS were adjusted until no further contractions were noted...

G Paul Digoy, Scott D Burge
PURPOSE OF REVIEW: To review the literature on laryngomalacia that manifests in older children and contrast this with congenital laryngomalacia seen more prevalently in infants. In doing so, we hope to offer relevant diagnostic and management options to treat late-onset laryngomalacia based from our experience and the current literature. RECENT FINDINGS: Laryngomalacia in older children can present differently than congenital laryngomalacia, and the most common and best understood consequence of late-onset laryngomalacia is obstructive sleep apnea syndrome...

Pediatric stridor is usually due to benign laryngomalacia. This pathology of unknown origin usually heals spontaneously during the first 18 months of life. Mild laryngomalacia is characterized by normal weight growth, the absence of sleep apneas and of associated swallowing or neurological disorders. Medical treatment is sufficient to release symptoms. Severe clinical forms are more rare, representing about 10 % of cases. They require an endoscopic evaluation of the upper airway under general anesthesia, as well as an endoscopic suppraglottoplasty...

BACKGROUND: Neurofibromatosis type 1 can rarely present in the larynx. Patients typically do not present with complete obstructive symptoms, but partial obstruction and stridor. We review our health centers' case series of two patients, the first of whom presented with persistent sleep apnea post tonsillectomy and adenoidectomy, and the second who presented with noisy breathing. Additionally, we will review the literature on the management and treatment options for children with this rare clinical entity...

IMPORTANCE: Laryngomalacia (LM) classically presents with stridor in early infancy but can present atypically with snoring and/or sleep-disordered breathing (S-SDB) or swallowing dysfunction (SwD). The epidemiology of these atypical presentations has not been established in the literature. OBJECTIVE: To document the primary modes of presentation for LM in a consecutive series of children and to compare the characteristics of each subgroup. DESIGN, SETTING, AND PARTICIPANTS: Retrospective case series in a single tertiary pediatric otolaryngology practice...

Breathing disorders like sleep apnea, stridor, and dysrythmic breathing are frequent in patients with multiple system atrophy (MSA). These observations have been related to neurodegeneration in several pontomedullary respiratory nuclei and may explain the occurrence of sudden death. In this study, we sought to determine whether these functional and neuropathological characteristics could be replicated in a transgenic model of MSA. Mice expressing human wild-type α-synuclein under the control of the proteolipid promoter (PLP-αSYN) were compared with age-matched controls...

UNLABELLED: Multiple system atrophy (MSA) is associated with respiratory dysfunction, including sleep apnea, respiratory dysrhythmia, and laryngeal stridor. Neurons of the parabrachial nucleus (PBN) control respiratory rhythmogenesis and airway resistance. OBJECTIVES: The objective of this study is to determine whether there was involvement of putative respiratory regions of the PBN in MSA. METHODS: We examined the pons at autopsy in 10 cases with neuropathologically confirmed MSA and 8 age-matched controls...

Respiratory stridor in patients with multiple system atrophy is a complication that occasionally causes nocturnal sudden death. Continuous positive airway pressure (CPAP) therapy has been proposed as an alternative to tracheostomy to treat nocturnal stridor associated with multiple system atrophy. However, some patients cannot tolerate CPAP therapy and experience sleep disturbances, even if the pressure is controlled; also, CPAP therapy can be less effective in patients with a narrow glottic opening during sleep...

Laryngomalacia is defined as collapse of supraglottic structures during inspiration. It is the most common laryngeal disease of infancy. Laryngomalacia presents in the form of stridor, a high-pitched, musical, vibrating, multiphase inspiratory noise appearing within the first 10 days of life. Signs of severity are present in 10% of cases: poor weight gain (probably the most contributive element), dyspnoea with permanent and severe intercostal or xyphoid retraction, episodes of respiratory distress, obstructive sleep apnoea, and/or episodes of suffocation while feeding or feeding difficulties...

We present a case of obstructive sleep apnea (OSA) that required multilevel surgical correction of the airway and literature review and discuss the role supraglottic laryngeal collapse can have in OSA. A 34-year-old man presented to a tertiary otolaryngology clinic for treatment of OSA. He previously had nasal and palate surgeries and a Repose tongue suspension. His residual apnea hypopnea index (AHI) was 67. He had a dysphonia associated with a true vocal cord paralysis following resection of a benign neck mass in childhood...

Sleep disorders in multiple system atrophy (MSA) are common manifestation and include reduced and fragmented sleep, excessive daytime sleepiness, REM sleep behaviour disorder (RBD), and sleep-disordered breathing. Of these, RBD is the most common (affecting 90 %-100 % of patients with MSA) and is regarded as a red flag for MSA. RBD, as well as stridor during sleep, may be the initial manifestation of the disease, occurring several years before the waking motor and dysautonomic onset. Sleep disorders occur in both MSA with predominant parkinsonism (MSA-P) and MSA with predominant cerebellar ataxia (MSA-C)...
