Movement Disorder Emergencies of the Upper Aerodigestive Tract
Movement disorder emergencies of the aerodigestive tract are dramatic and often life threatening. With appropriate timely evaluation and intervention, most patients can be effectively managed and major morbidity avoided. This chapter provides a comprehensive review of both the causes and appropriate treatment of breathing disturbances secondary to primary disorders and iatrogenic causes, as well as swallowing emergencies. Additionally, basic physiology, anatomy, and various methods for assessment of the upper aerodigestive tract are reviewed. Specific disorders that are addressed include the following: spasmodic dysphonia, adductor laryngeal breathing dystonia, Shy-Drager abductor weakness, drug-induced tardive dystonia, oromandibulolingual dystonia, multiple system atrophy, multiple sclerosis, amyotrophic lateral sclerosis, Parkinson's disease, Huntington's disease, and palatal myoclonus.
Multisystem inflammatory syndrome in children (MIS-C) and retropharyngeal edema: A case series
Multisystem inflammatory syndrome in children (MIS-C) is thought to follow SARS-CoV-2 infection and presents with fever and multisystem dysfunction. We report three children with suspected MIS-C found to have retropharyngeal edema without evidence of a bacterial etiology. We raise the possibility that an association between MIS-C and retropharyngeal edema exists.
Bradycardia and hypotension necessitating CPR in a healthy adolescent following injection of a local anesthetic into the nasal septum: A case report, review of the literature and suggested immediate management
General and local anesthetics are generally well tolerated in the healthy population. Complications may arise affecting the surgical and anesthetic course. We present a case of severe bradycardia and hypotension, along with ST depressions which developed following general anesthesia and local injection of lidocaine with epinephrine to the nose in a healthy male during routine otolaryngological surgery. Symptoms improved with atropine, epinephrine and chest compressions. Subsequent electrocardiogram and Troponin were abnormal, and normalized within days. Reviewing the literature, several possible etiologies arise. These include the Trigeminocardiac Reflex, Takotsubo cardiomyopathy and others. These are discussed and the condition's immediate management recommended.
International Pediatric Otolaryngology Group (IPOG) management recommendations: Pediatric tracheostomy decannulation
OBJECTIVES/OBJECTIVE:To provide recommendations to otolaryngologists, pulmonologists, and allied clinicians for tracheostomy decannulation in pediatric patients. METHODS:An iterative questionnaire was used to establish expert recommendations by the members of the International Pediatric Otolaryngology Group. RESULTS:Twenty-six members completed the survey. Recommendations address patient criteria for decannulation readiness, airway evaluation prior to decannulation, decannulation protocol, and follow-up after both successful and failed decannulation. CONCLUSION/CONCLUSIONS:Tracheostomy decannulation recommendations are aimed at improving patient-centered care, quality and safety in children with tracheostomies.
Pediatric Otolaryngology in the COVID-19 Era
Although the majority of attention to the health care impact of COVID-19 has focused on adult first responders and critical care providers, the pandemic has had a profound effect on the entire health care industry, including the pediatric otolaryngology community. This article highlights the unique ramifications of COVID-19 on pediatric otolaryngology, with a focus on the immediate and potential long-term shifts in practice. Specifically, the article is divided into 3 sections (care for the patient, care for the practitioner, and care for the practice) and details the unique effects of the pandemic on the pediatric otolaryngology specialty.
Complex mediastinal infection causing bilateral airway obstruction in a young child: Pulmonary mycobacterium avium infection and the role of surgical intervention in the compromised airway
Mycobacterium avium-intracellulare complex (MAC) is one of the most common forms of non-tuberculous mycobacterial (NTM) infection. MAC is a ubiquitous bacterium that resides in both natural and man-made environments. Surgical intervention is well established in NTM infections causing cervical lymphadenitis, but its role in airway disease is not well understood. Invasive pulmonary infection is usually associated with immunocompromised patients, but it occurs in otherwise healthy children as well. We present a challenging clinical case of an 18-month-old female with severe mediastinal MAC causing bilateral bronchogenic obstruction and respiratory compromise requiring emergent intubation and intervention, likely due to a genetic predisposition secondary to Interferon Gamma Receptor 2 (IFNGR2) haploinsufficiency. During the initial bronchoscopy, the left bronchus was 99% obstructed while the right bronchus was 60% obstructed. The right lesion was biopsied and drained whitish fluid with improvement in clinical status shortly thereafter. A culture was sent. Follow-up bronchoscopy with excision of residual right mass allowed for extubation in the operating room with discharge on azithromycin, rifabutin, and ethambutol. Repeat bronchoscopy after discharge revealed recurrence of bilateral lesions. The patient was started on nebulized amikacin in addition to her current regimen with full resolution after treatment. Despite subtotal removal of MAC lesions possibly increasing the chances of recurrence, surgical intervention in this patient resulted in rapid improvement in respiratory status, and it may represent the preferred treatment in patients with any airway concerns.
International Pediatric Otolaryngology Group (IPOG): Consensus recommendations on the prenatal and perinatal management of anticipated airway obstruction
OBJECTIVE:To make recommendations on the identification, routine evaluation, and management of fetuses at risk for airway compromise at delivery. METHODS:Recommendations are based on expert opinion by members of the International Pediatric Otolaryngology Group (IPOG). A two-iterative Delphi method questionnaire was distributed to all members of the IPOG and responses recorded. The respondents were given the opportunity to comment on the content and format of the survey, which was modified for the second round. "Consensus" was defined by >80% respondent affirmative responses, "agreement" by 51-80% affirmative responses, and "no agreement" by 50% or less affirmative responses. RESULTS:Recommendations are provided regarding etiologies of perinatal airway obstruction, imaging evaluation, adjunct evaluation, multidisciplinary team and decision factors, micrognathia management, congenital high airway obstruction syndrome management, head and neck mass management, attended delivery procedure, and delivery on placental support procedure. CONCLUSIONS:Thorough evaluation and thoughtful decision making are required to optimally balance fetal and maternal risks/benefits.
Proton pump inhibitor administration in neonates and infants. Lack of consensus - An ASPO survey
OBJECTIVE:Laryngopharyngeal and Gastroesophageal reflux (LPR and GER) are distinct clinical entities that present with a range of non-specific symptoms. The exact prevalence in the pediatric population is unknown. While there has been an increase in the use of PPIs, lack of clear guidelines, conflicting evidence regarding efficacy and safety concerns with long-term use require physicians to use their own anecdotal experience and clinical judgement when treating patients. The goal of this study was to evaluate practice patterns among pediatric otolaryngologists regarding the use of proton-pump inhibitors for reflux-related conditions. METHODS:A survey was submitted to American Society of Pediatric Otolaryngology (ASPO) members to determine practice patterns regarding use of PPIs for reflux-related conditions in the newborn and infant population. Statistical analysis using Fisher's exact test was performed. RESULTS:37% of respondents would not prescribe PO PPIs in neonates, with 50% not prescribing IV PPIs. 60% would prescribe a PPI as second or third-line treatment for infants (10 weeks to 1-year). Only 10% would prescribe as first-line in this age group. 48% would prescribe PPIs once daily and 19% as BID. No significant practice differences exist based on years of experience, number of relevant patients seen, and setting of practice. CONCLUSION/CONCLUSIONS:There was no agreement regarding dosage, frequency and duration of PPI treatment for reflux disease in neonates and infants. There was also no correlation with experience or practice setting. This emphasizes the need for a multidisciplinary approach and consensus statement to guide management of GER and LPR in this population.
Sleep-Disordered Breathing and Airway Assessment Using Polysomnography in Pediatric Patients With Craniofacial Disorders
Children with cleft and craniofacial conditions commonly present with concurrent airway anomalies, which often manifest as sleep disordered breathing. Craniofacial surgeons and members of the multidisciplinary team involved in the care of these patients should appreciate and understand the scope of airway pathology as well as the proper means of airway assessment. This review article details the prevalence and assessment of sleep disordered breathing in patients with craniofacial anomalies, with emphasis on indications, limitations, and interpretation of polysomnography.
Granulomas of the membranous vocal fold after intubation and other airway instrumentation
OBJECTIVES/HYPOTHESIS/OBJECTIVE:We describe the clinical features of granulomas of the membranous vocal fold secondary to endotracheal intubation, bronchoscopy or esophagogastroduodenoscopy. STUDY DESIGN/METHODS:Retrospective case series. METHODS:Review of cases at a single tertiary institution with evaluation of patient demographic characteristics, time to presentation, time to treatment, and clinical outcomes. RESULTS:Thirteen adult patients were identified with postintervention granuloma of the membranous vocal fold. All patients were female, with a mean age of 60 years (range, 28-81 years). None noted hoarseness prior to the intervention, and all noted significant hoarseness postoperatively. Conservative treatment with proton pump inhibitors and vocal rest was initially implemented in all patients. Four cases resolved without further intervention. Nine underwent surgical management because of airway symptoms, failure to improve, or patient request. One patient had injury to the contralateral vocal fold upon intubation. None experienced recurrence. Five had complete recovery of voice postoperatively, four did not. CONCLUSION/CONCLUSIONS:Iatrogenic granulomas of the membranous vocal fold after intubation or other upper airway instrumentation are rare complications presenting in the early postprocedure period with worsening hoarseness. Initial conservative treatment may be sufficient to yield resolution, and surgical treatment is effective for those failing medical management. Permanent voice damage may result from the original injury. LEVEL OF EVIDENCE/METHODS:4. Laryngoscope, 2018.
