ABSTRACT
Introduction: Stress may serve as an adjunct (challenge) or hindrance (threat) to the learning process. Determining the effect of an individual's response to situational demands in either a real or simulated situation may enable optimisation of the learning environment. Studies of acoustic analysis suggest that mean fundamental frequency and formant frequencies of voice vary with an individual's response during stressful events. This hypothesis is reviewed within the otolaryngology (ORL) simulation environment to assess whether acoustic analysis could be used as a tool to determine participants' stress response and cognitive load in medical simulation. Such an assessment could lead to optimisation of the learning environment. Methodology: ORL simulation scenarios were performed to teach the participants teamwork and refine clinical skills. Each was performed in an actual operating room (OR) environment (in situ) with a multidisciplinary team consisting of ORL surgeons, OR nurses and anaesthesiologists. Ten of the scenarios were led by an ORL attending and ten were led by an ORL fellow. The vocal communication of each of the 20 individual leaders was analysed using a long-term pitch analysis PRAAT software (autocorrelation method) to obtain mean fundamental frequency (F0) and first four formant frequencies (F1, F2, F3 and F4). In reviewing individual scenarios, each leader's voice was analysed during a non-stressful environment (WHO sign-out procedure) and compared with their voice during a stressful portion of the scenario (responding to deteriorating oxygen saturations in the manikin). Results: The mean unstressed F0 for the male voice was 161.4 Hz and for the female voice was 217.9 Hz. The mean fundamental frequency of speech in the ORL fellow (lead surgeon) group increased by 34.5 Hz between the scenario's baseline and stressful portions. This was significantly different to the mean change of -0.5 Hz noted in the attending group (p=0.01). No changes were seen in F1, F2, F3 or F4. Conclusions: This study demonstrates a method of acoustic analysis of the voices of participants taking part in medical simulations. It suggests acoustic analysis of participants may offer a simple, non-invasive, non-intrusive adjunct in evaluating and titrating the stress response during simulation.
ABSTRACT
Aerosolization procedures during the COVID-19 pandemic place all operating room personnel at risk for exposure. We offer detailed perioperative management strategies and present a specific protocol designed to improve safety during pediatric laryngoscopy and bronchoscopy. Several methods of using disposable drapes for various procedures are described, with the goal of constructing a tent around the patient to decrease widespread contamination of dispersed droplets and generated aerosol. The concepts presented herein are translatable to future situations where aerosol generating procedures increase risk for any pathogenic exposure. This protocol is a collaborative effort based on knowledge gleaned from clinical and simulation experience from Children's Hospital Colorado, Children's Hospital of Philadelphia, The Hospital for Sick Children in Toronto, and Boston Children's Hospital.

OBJECTIVES/HYPOTHESIS: Describe augmentative communication tools and strategies used by pediatric patients referred to inpatient speech-language pathologists prior to tracheostomy placement. STUDY DESIGN: Retrospective review. METHODS: A review of patients who underwent initial tracheostomy placement from 2013-2016 was conducted at a tertiary pediatric center. Eligible patients were those who were referred to a specialized speech-language pathologist prior to the date of the tracheostomy placement to support communication abilities. Patients were identified by surgical procedural and billing codes. Data collected included patient demographics, speech and language disorders, and interventions performed. Chart review and cross analysis of billing data for types of assessment and intervention procedures were conducted by two speech-language pathologists for consensus agreement. RESULTS: Forty-six patients (aged 1 month-27 years, mean = 12.9 years) were included in the study. Average time between the bedside communication assessment and tracheostomy procedure date was 17 days. Baseline speech-language disorders were identified in 11 patients (24%). Thirty-eight (83%) patients were nonspeaking at the time of consultation. Thirty-two (70%) patients utilized an electronic communication tool, and 36 (78%) utilized low-technology communication strategies during the preoperative period. A total of 32 (70%) patients were documented as using no-technology or speech-enhancement strategies during the acute hospitalization. CONCLUSIONS: Multidisciplinary tracheostomy teams should consider consultation to speech-language pathologists for patients prior to tracheostomy placement to assess for utility of high-technology, low-technology, and no-technology augmentative and alternative communication strategies.

IMPORTANCE: Incidence of tracheostomy placement in children is increasing, and these children continue to have high incidences of morbidity and mortality. A multidisciplinary tracheostomy program may help improve the quality of care received by these patients. OBJECTIVE: To determine whether implementation of a multidisciplinary tracheostomy program can improve the care of children who received a tracheostomy through reduction in tracheostomy-related adverse events (TRAEs), improved tracheostomy education, and caregiver preparedness. DESIGN, SETTING, AND PARTICIPANTS: A prospective cohort study was conducted from January 2015 to June 2018 at a pediatric tertiary referral center in Boston, Massachusetts. The participants included 700 children who had received a tracheostomy, most of whom were aged birth to 18 years, but some patients with congenital disorders were much older. EXPOSURES: Institution of a multidisciplinary tracheostomy team (MDT) whose activities included conducting staff meetings, organizing outpatient clinics, conducting inpatient tracheostomy ward rounds, and conducting inpatient tracheostomy rounds at a local rehabilitation hospital. Quality improvement initiatives included monitoring standardized TRAEs and distributing standardized tracheostomy "go-bags." MAIN OUTCOMES AND MEASURES: Reduction of TRAEs and improved caregiver preparedness through distribution of tracheostomy go-bags were assessed following the establishment of a multidisciplinary tracheostomy program. RESULTS: In total, 700 children who had received a tracheostomy during the study period were actively followed up by the MDT. Of these children, 378 (54.0%) were males and 322 (46.0%) were females; mean (SD) age was 4.1 (6.1) years. More than 60 new pediatric tracheostomies were performed annually at the referral center. Reported TRAEs were reduced by 43.0% from the first to the third year after the implementation of a standardized, closed-loop monitoring system (from a mean [SD] of 6.1 [5.2] TRAEs per 1000 inpatient tracheostomy-days in 2015 to a mean [SD] of 4.0 [2.5] in 2018). The most common TRAE was unplanned decannulation, which occurred 64 times during the study period. On average, 10 patients were seen in each monthly multidisciplinary tracheostomy clinic. Clinic interventions included continuing care (146 [52.5%]), communication enhancement (67 [23.6%]), plans for decannulation (52 [18.6%]), and referrals for comorbidities (13 [4.6%]). Approximately 19 inpatients were seen during biweekly rounds and 8 during monthly rounds at a local rehabilitation hospital. A total of 297 patients received standardized tracheostomy go-bags, and more than 70 positive bag checks were performed in the monthly MDT clinics. A positive bag check refers to the incidence when a family is given a go-bag and also uses it. In contrast, a negative bag check refers to when a family is given a go-bag but neither brings it to the clinic nor acknowledges that they use it. CONCLUSIONS AND RELEVANCE: This study's findings suggest that a multidisciplinary tracheostomy program may be a powerful tool for enhancing patient safety and quality improvement. Ongoing studies will develop measurable pediatric tracheostomy outcome metrics and assess long-term outcomes.
ABSTRACT
OBJECTIVES/HYPOTHESIS: Advancement in neonatal and pediatric intensive care has increased the need for chronic-care interventions, including tracheostomy. It is well established that children with a tracheostomy are at a high risk for adverse events, many of which are preventable. Despite this, there is no standardized method of monitoring tracheostomy-related adverse events (TRAEs). Our objective was to describe and assess a standardized, closed-loop system for monitoring TRAEs. STUDY DESIGN: Prospective Study. METHODS: A specific tracheostomy-related category was established within the adverse event reporting system in January 2015. Monthly TRAE reports were supplied to the multidisciplinary tracheostomy team (MDT) with descriptions of event type, severity, and preventability. The MDT reviewed events and discussed necessary follow-up. The frequency of events was standardized by inpatient tracheostomy days (ITDs) using an automated monthly list. Adverse events were tracked using a control chart. Aggregated data were divided into biannual reports for analysis. RESULTS: Eighty-five TRAEs were reported between January 2015 and June 2017, averaging 5.75 per 1,000 ITDs. Most common events include unplanned decannulation (50%) and improper use of tracheostomy supplies (21%). The frequency of all preventable events has decreased by 76% since the second half of 2015. During this timeframe, minor events have decreased, moderate events have maintained a frequency of less than one per 1,000 ITDs, and only one severe event occurred. CONCLUSIONS: This standardized, closed-loop reporting method, modeled after other successful intensive care unit reporting systems, accurately tracks TRAEs. We have observed a decrease in preventable TRAEs without a negative impact on rates of severe events. Results suggest improved quality of care for patients with tracheostomy. LEVEL OF EVIDENCE: 4.

American health care is facing an epidemic of medical errors. A major cause of these errors is poor teamwork. Crisis resource management (CRM) is a set of teamwork principles derived from the airline industry. Medical simulation is an educational tool that affords health care providers a means of improving teamwork by learning and practicing CRM. This article (1) discusses the case for teaching team training, (2) reviews the principles of medical simulation as they pertain to team training, (3) provides practical guidelines for using medical simulation in otolaryngology education, (4) discusses current evidence for the efficacy of medical simulation.

OBJECTIVES: To develop consensus recommendations for peri-operative tracheotomy care in pediatric patients. METHODS: Expert opinion by the members of the International Pediatric Otolaryngology Group (IPOG). The mission of the IPOG is to develop expertise-based consensus recommendations for the management of pediatric otolaryngologic disorders with the goal of improving patient care. The consensus recommendations herein represent the first publication by the group. RESULTS: Consensus recommendations including pre-operative, intra-operative, and post-operative considerations, as well as sedation and nutrition management are described. These recommendations are based on the collective opinion of the IPOG members and are targeted to (i) otolaryngologists who perform tracheotomies on pediatric patients, (ii) intensivists who are involved in the shared-care of these patients, and (iii) allied health professionals. CONCLUSION: Pediatric peri-operative tracheotomy care consensus recommendations are aimed at improving patient-centered care in this patient population.

OBJECTIVES: Develop a course to use in situ high-fidelity medical simulation (HFS) in an actual operating room (OR) to (1) teach teamwork and crisis resource management (CRM) skills simultaneously to otolaryngology and anesthesia trainees and OR nurses and (2) provide decision-making experience to ear, nose, and throat residents and OR teams in simulated high-risk, low-frequency airway emergencies. STUDY DESIGN: A simulation-based, in situ CRM course was developed to teach airway management and CRM in the OR. Upon completion of each course, the participants were surveyed using questions with (1-5) scale answers. SETTING: The simulated clinical scenarios took place in the intensive care unit and OR at Children's Hospital Boston. SUBJECTS AND METHODS: The participants consisted of pediatric otolaryngology fellows, otolaryngology residents, anesthesiology residents, fellows, and certified registered nurse anesthetists as well as OR nurses. Fifty-nine individuals participated in 9 simulation-based courses given between October 2008 and May 2010. The team members participated together in 3 simulated medical crises that centered on airway and anesthesia issues. Each simulated crisis was followed by a structured debriefing session conducted by trained debriefers. Embedded within the course were didactics on CRM principles. RESULTS: The participants' responses on the survey included General Course Organization, Realism, Debriefing, and Relevance to Future Practice. Ninety percent of the responses were favorable or very favorable. CONCLUSION: Using a newly developed, in situ HFS-based course, clinical decision-making skills and teamwork can be effectively taught concurrently to members of an OR team.

OBJECTIVE: To assess the efficacy and safety of endoscopic management of subglottic stenosis both as a primary and as an adjunctive treatment in the pediatric population. METHODS: Retrospective review of pediatric patients with subglottic stenosis undergoing endoscopic airway procedures at a tertiary care pediatric medical center. Outcomes were assessed by systematic review to determine the success and failure of the endoscopic approach. RESULTS: Forty patients (22 male, 18 female) underwent endoscopic interventions for a diagnosis of subglottic airway stenosis between 2003 and 2006. Age ranged from 22 days old to 20 years old. Recorded degree of subglottic stenosis ranged from 10% to 99%. Fifty-three percent (21/40) had a history of prematurity, and 40% (16/40) had secondary airway diagnoses. Twenty-four patients underwent an endoscopic intervention initially (including laser or dilation, with or without topical mitomycin treatment), including four patients who underwent tracheostomy prior to the first endoscopic intervention. Sixteen underwent laryngotracheoplasty initially, including ten patients who underwent tracheostomy prior to the laryngotracheoplasty. Endoscopic treatment resulted in resolution of symptoms, and/or decannulation, and no further need for an open procedure in 58% of patients. Of the 24 patients undergoing endoscopic interventions initially, 14 patients underwent two or more endoscopic interventions, and 10 patients subsequently required tracheostomy or laryngotracheoplasty. When endoscopic procedures were used as an adjunct to laryngotracheoplasty, 60% (12/20) had resolution of symptoms, underwent decannulation, and did not require tracheostomy or revision laryngotracheoplasty. CONCLUSIONS: The endoscopic approach can be successful in the management of properly selected patients with subglottic stenosis, either as the initial treatment modality or as an adjunctive treatment in cases of re-stenosis after open airway surgery. The likelihood of success with a minimally invasive procedure as the primary treatment decreases with worsening initial grade of subglottic stenosis.

OBJECTIVES: We examined the relationship between the size of vocal fold nodules and perceptual rating of voice quality in children. METHODS: We carried out an Institutional Review Board-approved retrospective study in a voice clinic within a tertiary-care pediatric medical center. We studied children seen between 2000 and 2009 with a primary diagnosis of vocal fold nodules as the cause of their voice disturbance. Pediatric vocal fold nodule size was rated with a published validated scale, and voice quality was rated on the Consensus Auditory-Perceptual Evaluation of Voice scale. RESULTS: One hundred forty-five patients met the inclusion criteria. Small nodules were noted in 23% of patients, medium nodules in 39%, and large nodules in 37%. Univariate and multivariate analyses demonstrated a statistically significant relationship (p < 0.05) between vocal fold nodule size and rated perceptual qualities of overall severity of voice disturbance, roughness, strain, pitch, and loudness. With the exception of loudness, as vocal fold nodule size increased, the mean value of perceptual characteristics became larger. The age of the patient was a significant factor associated with the overall severity of the voice disturbance and roughness. CONCLUSIONS: The overall severity of a child's voice disturbance and qualities of roughness, strain, pitch, and loudness have a strong correlational relationship with pediatric vocal fold nodule size, which is suggestive of causality.

In teleosts, gonadotropin (GTH) secretion and synthesis is controlled by multiple neuroendocrine factors from the hypothalamus, pituitary and peripheral sources. Pituitary gonadotropes must be able to differentiate and integrate information from these regulators at the cellular and intracellular level. In this article, the intracellular signal transduction mechanisms mediating the actions of some of these regulators, including GTH-releasing hormones, pituitary adenylate cyclase-activating polypeptide, dopamine, ghrelin, sex steroids, activin, and follistatin from experiments with goldfish are reviewed and discussed in relation with recent findings. Information from other teleost models is briefly compared. Goldfish gonadotropes possess multiple pharmacologically distinct intracellular Ca2+ stores that together with voltage-sensitive Ca2+ channels, Na+/H+ exchangers, protein kinase C, arachidonic acid, NO, protein kinase A, ERK/MAPK, and Smads allows for integrated control by different neuroendocrine factors.

OBJECTIVE: To validate the Pediatric Voice-Related Quality-of-Life (PVRQOL) survey, which was designed to assess voice changes over time in the pediatric population. DESIGN: Prospective longitudinal study. SETTING: Outpatient pediatric otolaryngology office practice. PARTICIPANTS: One hundred twenty parents of children aged 2 through 18 years having a variety of otolaryngological diagnoses including disorders that affect the voice. INTERVENTIONS: The previously validated Pediatric Voice Outcomes Survey and the PVRQOL were jointly administered to the parents of the study participants. Test-retest reliability was accomplished by having 70 caregivers repeat the instrument 2 weeks after the initial visit. The Cronbach alpha value was calculated to determine reliability. Instrument validity was determined by examining convergent and discriminant validity. MAIN OUTCOME MEASURE: Correlation of PVRQOL scores with Pediatric Voice Outcomes Survey scores. RESULTS: Reliability of the PVRQOL was established by evaluating the Cronbach alpha value (.96; P<.001) and by test-retest reliability (weighted kappa value, 0.8). Validity of the PVQROL was tested by evaluating its ability to show significant change in voice-related quality-of-life after adenoidectomy (discriminant validity) (P<.001). The PVQROL also proved valid when the overall score was correlated with the previously validated Pediatric Voice Outcomes Survey (r = 0.7; P<.001). CONCLUSION: The PVRQOL is a more comprehensive survey than the previously validated Pediatric Voice Outcomes Survey and is another valid instrument to examine the health-related quality-of-life issues in pediatric voice disorders.

We present a case of a congenital fetal rhabdomyoma which recurred after surgical excision. A review of the patient's chart, imaging studies, operative reports and histologic findings were conducted. A congenital fetal rhabdomyoma involving the head and neck region diagnosed prenatally by ultrasound and MRI was surgically excised without complications. The patient presented with recurrence of the tumor fourteen months after the initial surgery. This case report is supplemented with a review of the relevant literature on congenital fetal rhabdomyoma. This is the fifth documented case of recurrence of a fetal rhabdomyoma. Extracardiac rhabdomyomas are extremely rare benign tumors. Complete excision of these lesions is curative with only a handful of recurrences documented in the literature. Close follow up and a complete workup to rule out rhabdomyosarcoma is warranted in all cases of recurrence.

OBJECTIVES: Review a large series of patients with Robin sequence to document the incidence of (1) associated syndromic diagnoses; (2) co-morbid conditions; (3) frequency and type of operative management for airway compromise and feeding difficulties; and (4) possible differences in treatment between syndromic and nonsyndromic infants. METHODS: Retrospective case-review of 115 patients with Robin sequence managed between 1962 and 2002 at two tertiary-care teaching hospitals for evaluation of demographic information, clinical findings, and treatment interventions. RESULTS: Fifty-four percent (N=63) of patients were nonsyndromic. Syndromic patients included: Stickler syndrome (18%), velocardiofacial syndrome (7%), Treacher-Collins (5%), facial and hemifacial microsomia (3%), and other defined (3.5%) and undefined (9%) disorders. There was no statistical difference between the syndromic and nonsyndromic patients with regard to need for operative airway management (Fisher's exact test, p=0.264). Forty-two percent of patients required a feeding gastrostomy tube to correct feeding difficulties. Patients with a syndromic diagnosis were more likely to be developmentally delayed. Fifty-one (44%) patients underwent operative airway management: 61% underwent tongue-lip adhesion and 39% underwent tracheotomy. Fifteen percent of patients initially had tongue-lip adhesion subsequently required tracheotomy. While the preferred treatment for respiratory compromise differed between the two institutions, the percentage of patients requiring operative intervention was similar. CONCLUSIONS: The pathogenesis of Robin sequence is multifactorial and syndromic in nearly half of the patients. Operative treatment of respiratory failure was required in 44% of infants; the rate was similar in both hospitals. The operative approach differed significantly between the institutions, however, based on the philosophy and training of the managing surgical specialty. Co-morbid factors such as baseline cardiopulmonary and neurologic status did not play a significant role in surgical decision making.

OBJECTIVE: To establish normative values for voice-related quality of life across a broad pediatric otolaryngology population using the Pediatric Voice Outcome Survey (PVOS). DESIGN: Longitudinal study. SETTING: Multiphysician outpatient pediatric otolaryngology practice. METHODS: The PVOS was completed by 385 parents of children and adolescents aged 2 to 18 years. Of the 385 parents, 75 were readministered the instrument 2 weeks after no intervention had been provided. Data were collected regarding the patients' age, main diagnosis, and operative intervention. RESULTS: The PVOS demonstrated robust internal consistency with an overall Cronbach alpha value of.70. Test-retest reliability demonstrated a weighted kappa value of 0.89 (95% confidence interval, 0.84-0.95) The mean +/- SD converted score (based on a 0-100 scale) for the overall population was 80.5 +/- 19.9. Converted PVOS scores are provided for each subpopulation according to main diagnosis. The PVOS scores varied significantly according to age (P<.05) and preoperative and postoperative status following adenoidectomy (P<.05). CONCLUSION: The PVOS represents a valid and reliable instrument to measure voice-related quality of life in a broad pediatric otolaryngology population.
