Clinical Trials


  • In Infants With Laryngomalacia, Does Acid-Blocking Medication Improve Respiratory Symptoms? Not Recruiting

    All neonates, ages 0 to 4 months, presenting to LPCH pediatric ENT clinic for airway difficulties or stridor will be screened for inclusion. As is consistent with an acceptable standard of medical care, these children will undergo a flexible nasal endoscopic exam to make the diagnosis of laryngomalacia, as well as be weighed and a breastfeeding history taken. If laryngomalacia is present, the study staff with then administer the Infant Gastroesophageal Reflux Questionnaire (IGERQ) and an airway symptoms questionnaire (ASQ). Those babies with an IGERQ score of less than sixteen (no more than mild reflux) and an ASQ score greater than six will be eligible for randomization. The patient will then be randomly placed in the control group (placebo) or the intervention group (ranitidine 2mg/kg every 12 hours or famotidine 0.5 mg/kg daily). Patients will stay on medication for a minimum of 6 months, or until symptoms resolve. Patients will be seen in follow up at 1, 2, 3, 4, 5, 6, 8 and 10 months. At which time I-GERQ, ASQ and weights will be taken. The primary outcome measure will be the time for the ASQ score to drop to normal on ranitidine or famotidine versus placebo. A secondary outcome will be weight gain in percentile. If the patient's I-GERQ score goes above 16 at any time in the study, the patient will be crossed over to the treatment arm and started on medical treatment.

    Stanford is currently not accepting patients for this trial. For more information, please contact Lorene Nelson, PhD, 650-723-6854.

  • Transnasal Humidified Rapid-Insufflation Ventilatory Exchange (THRIVE) Use in Pediatric Procedures Not Recruiting

    THRIVE (Transnasal Humidified Rapid-Insufflation Ventilatory Exchange) refers to the use of high-flow nasal cannula to augment the ability to oxygenate and ventilate a patient under general anesthesia. The use of high-flow nasal cannula oxygen supplementation during anesthesia for surgical procedures has been a recent development in the adult population, with limited data analyzing the pediatric population. This study will determine whether high flow nasal cannula oxygen supplementation during surgical or endoscopic procedures can safely prevent desaturation events in children under anesthesia.

  • Safety and effectiveness of vocal fold injection laryngoplasty in infants less than one year of age. International journal of pediatric otorhinolaryngology Ayoub, N., Balakrishnan, K., Meister, K., Grimm, D., Johnson, A., Maida, K., Sidell, D. R. 2023; 168: 111542

    Abstract

    Injection laryngoplasty (IL) is commonly performed for unilateral vocal fold immobility (UVFI). However, the safety and efficacy in patients <1 year of age are not widely recognized. This study analyzes the safety and swallow outcomes in a cohort of patients <1 year who underwent IL.This retrospective analysis evaluated patients at a tertiary children's institution between 2015 and 2022. Patients were eligible if they underwent IL for UVFI and were <1 year at time of injection. Baseline characteristics, perioperative data, oral diet tolerance, and preoperative and postoperative swallow data were collected.49 patients were included, 12 (24%) of whom were premature. The average age at injection was 3.9 months (SD 3.8), time from UVFI onset to injection 1.3 months (2.0), and weight at injection 4.8 kg (2.1). The baseline American Association of Anesthesiologists physical status classification scores were 2 (14%), 3 (61%), and 4 (24%). 89% of patients had improvements in objective swallow function postoperatively. Of the 35 patients who were preoperatively enterally-dependent and did not have medical circumstances precluding advancement to oral feeds, 32 (n = 91%) tolerated an oral diet postoperatively. There were no long-term sequelae. Two patients had intraoperative laryngospasm, one intraoperative bronchospasm, and one with subglottic and posterior glottic stenosis was intubated for <12 h for increased work of breathing.IL is a safe and effective intervention that can reduce aspiration and improve diet in patients <1 year old. This procedure can be considered at institutions with the appropriate personnel, resources, and infrastructure.

  • Consensus on Triple Endoscopy Data Elements Preparatory to Development of an Aerodigestive Registry. The Laryngoscope Boesch, R. P., de Alarcon, A., Piccione, J., Prager, J., Rosen, R., Sidell, D. R., Wootten, C., Balakrishnan, K., Aerodigestive Research Collaborative 2022

    Abstract

    OBJECTIVES/HYPOTHESIS: This study defines essential data elements to be recorded during an aerodigestive "triple endoscopy" to form the foundation of a standardized multicenter registry and to clearly define measurement of each consensus item.STUDY DESIGN: Modified Delphi process.METHODS: Modified Delphi consensus with six survey rounds. Twenty-four expert pediatric otolaryngology, pulmonology, and gastroenterology aerodigestive clinicians from eight large academic pediatric aerodigestive programs formed the Delphi panel. After achieving consensus through the Delphi process, outside validation was performed at 2019 national Aerodigestive Society conference. Consensus, near-consensus, or exclusion was obtained for each proposed data element. Concordance was then measured between expert panel conclusions and validation group conclusions.RESULTS: Overall response rate was 94.4%. 73/167 proposed items reached consensus in six domains (flexible bronchoscopy, bronchoalveolar lavage, microdirect laryngoscopy and bronchoscopy, esophagogastroduodenoscopy with biopsies, and esophageal impedance and pH probe). Measurement of all items was defined; classification/grading systems were selected for 11 items. Validation group endorsed importance of 82/167 data items; compared to expert consensus, overall, inclusion, and exclusion concordance rates were 94.5%, 98.7%, and 90.9%.CONCLUSION: Triple endoscopy is a central component of aerodigestive care. This study identifies and defines data elements to be recorded for all triple endoscopy procedures. The list is of usable length, and clear definitions were created for all items, with explicit classification/grading systems selected for 11 items. Face validity was confirmed with an independent multispecialty sample of aerodigestive providers. This consensus provides the foundation for a triple endoscopy registry but also is immediately applicable to standardize clinical documentation in aerodigestive care.LEVEL OF EVIDENCE: 5 Laryngoscope, 2022.

    Abstract

    OBJECTIVES/HYPOTHESIS: The purpose of this study is to develop consensus on key points that would support the use of systemic bevacizumab for the treatment of recurrent respiratory papillomatosis (RRP), and to provide preliminary guidance surrounding the use of this treatment modality.STUDY DESIGN: Delphi method-based survey series.METHODS: A multidisciplinary, multi-institutional panel of physicians with experience using systemic bevacizumab for the treatment of RRP was established. The Delphi method was used to identify and obtain consensus on characteristics associated with systemic bevacizumab use across five domains: 1) patient characteristics; 2) disease characteristics; 3) treating center characteristics; 4) prior treatment characteristics; and 5) prior work-up.RESULTS: The international panel was composed of 70 experts from 12 countries, representing pediatric and adult otolaryngology, hematology/oncology, infectious diseases, pediatric surgery, family medicine, and epidemiology. A total of 189 items were identified, of which consensus was achieved on Patient Characteristics (9), Disease Characteristics (10), Treatment Center Characteristics (22), and Prior Workup Characteristics (18).CONCLUSION: This consensus statement provides a useful starting point for clinicians and centers hoping to offer systemic bevacizumab for RRP and may serve as a framework to assess the components of practices and centers currently using this therapy. We hope to provide a strategy to offer the treatment and also to provide a springboard for bevacizumab's use in combination with other RRP treatment protocols. Standardized delivery systems may facilitate research efforts and provide dosing regimens to help shape best-practice applications of systemic bevacizumab for patients with early-onset or less-severe disease phenotypes.LEVEL OF EVIDENCE: 5.

    Abstract

    This case series examines interactive AR during minor otolaryngologic procedures. Although VR has been successfully used for pediatric vascular access, removing children from comforting people in the real world has resulted in patient anxiety. AR offers a potential advantage, utilizing distracting holographic images when patients maintain eye contact with parents. The primary objective was to determine the effect of AR on fear during pediatric otolaryngologic procedures. Secondary objectives included evaluating pain; procedure compliance; and patient, parent and physician attitudes toward AR, as well as assessing the feasibility of adding AR to a busy outpatient otolaryngologic clinic.

  • The Relationship between Croup and Gastroesophageal Reflux: A Systematic Review and Meta-Analysis. The Laryngoscope Coughran, A. n., Balakrishnan, K. n., Ma, Y. n., Vaezeafshar, R. n., Capdarest-Arest, N. n., Hamdi, O. n., Sidell, D. R. 2020

    Abstract

    The mechanism by which recurrent croup occurs is unknown. Gastroesophageal reflux is commonly implicated, although this relationship is only loosely documented. We conducted a systematic review with a meta-analysis component to evaluate the relationship between recurrent croup and gastroesophageal reflux disease (GERD), and to assess for evidence of improvement in croup symptoms when treated.Systematic Review and Meta Analysis.We searched five separate databases. Studies were included if they discussed the relationship between croup and GERD in children, >5 subjects, and available in English. Literature retrieved was assessed according to pre-specified criteria. Retrieved articles were reviewed by two independent authors and decisions mediated by a third author. If there was a difference of opinion after first review, a second review was performed to obtain consensus. Heterogeneity was calculated and summarized in forest plots.Of 346 initial records, 15 met inclusion criteria. These were two retrospective cohort and 13 cross-sectional studies. Thirteen of 15 articles support an association between recurrent croup and GERD. Although heterogeneity is high among studies that reported prevalence of GERD, there is less uncertainty in results for improvement to recurrent croup after GERD treatment. Most studies lacked a control group and all carry a moderate-to-high risk of bias.There is limited evidence linking GERD to recurrent croup; Further research is needed to assess for causality as most studies are retrospective, lack a control group, and have a study design exposing them to bias. Patients treated with reflux medication appear to demonstrate a reduced incidence of croup symptoms.1 Laryngoscope, 2020.

    Abstract

    Develop multidisciplinary and international consensus on patient, disease, procedural, and perioperative factors, as well as key outcome measures and complications, to be reported for pediatric airway reconstruction studies.Standard Delphi methods were applied. Participants proposed items in three categories: 1) patient/disease characteristics, 2) procedural/intraoperative/perioperative factors, and 3) outcome measures and complications. Both general and anatomic site-specific measures were elicited. Participants also suggested specific operations to be encompassed by this project. We then used iterative ranking and review to develop consensus lists via a priori Delphi consensus criteria.Thirty-three pediatric airway experts from eight countries in North and South America, Europe, and Australia participated, representing otolaryngology (including International Pediatric Otolaryngology Group members), pulmonology, general surgery, and cardiothoracic surgery. Consensus led to inclusion of 19 operations comprising open expansion, resection, and slide procedures of the larynx, trachea, and bronchi as well as three endoscopic procedures. Consensus was achieved on multiple patient/comorbidity (10), disease/stenosis (7), perioperative-/intraoperative-/procedure-related (16) factors. Consensus was reached on multiple outcome and complication measures, both general and site-specific (8 general, 13 supraglottic, 15 glottic, 17 subglottic, 8 cervical tracheal, 12 thoracic tracheal). The group was able to clarify how each outcome should be measured, with specific instruments defined where applicable.This consensus statement provides a framework to communicate results consistently and reproducibly, facilitating meta-analyses, quality improvement, transfer of information, and surgeon self-assessment. It also clarifies expert opinion on which patient, disease, procedural, and outcome measures may be important to consider in any pediatric airway reconstruction patient.5 Laryngoscope, 129:244-255, 2019.

  • Application-Based Translaryngeal Ultrasound for the Assessment of Vocal Fold Mobility in Children. Otolaryngology--head and neck surgery : official journal of American Academy of Otolaryngology-Head and Neck Surgery Sayyid, Z. n., Vendra, V. n., Meister, K. D., Krawczeski, C. D., Speiser, N. J., Sidell, D. R. 2019: 194599819877650

    Abstract

    To compare the evaluation of vocal fold mobility between flexible nasal laryngoscopy (FNL) and a handheld application-based translaryngeal ultrasound (TLUS) platform.Prospective analysis included patients with unknown vocal fold mobility status who underwent FNL and TLUS.Tertiary referral center.TLUS was performed on 23 consecutive children (<18 years old) presenting for laryngoscopy due to unknown vocal fold mobility status. After the recording of three 10-second TLUS videos as well as FNL, the study was divided into 2 parts: parental assessment of laryngeal ultrasound at the time of patient evaluation and random practitioner assessment of ultrasound videos.We describe 23 patients who underwent TLUS and FNL. Ten patients (43.5%) had normal vocal fold function bilaterally, and 13 (56.5%) had either left or right vocal fold immobility. Family members and physicians correctly identified the presence and laterality of impaired vocal fold mobility in 22 of 23 cases (κ = 0.96). The sensitivity, specificity, positive predictive value, and negative predictive value of FLUS in diagnosing vocal fold immobility were 92.3%, 100%, 100%, and 90.9%, respectively. Random practitioners accurately identified the presence and laterality of vocal fold immobility under all circumstances.A handheld application-based ultrasound platform is both sensitive and specific in its ability to identify vocal fold motion impairment. Portable handheld TLUS has the potential to serve as a validated screening examination, even by inexperienced providers, and in specific cases may obviate the need for an invasive transnasal laryngoscopy.

  • Injection Laryngoplasty for Children with Unilateral Vocal Fold Paralysis: Procedural Limitations and Swallow Outcomes. Otolaryngology--head and neck surgery : official journal of American Academy of Otolaryngology-Head and Neck Surgery Meister, K. D., Johnson, A., Sidell, D. R. 2018: 194599818813002

    Abstract

    OBJECTIVE: Vocal fold immobility with resultant dysphagia is a known cause of morbidity in the pediatric population. Herein we evaluate the efficacy and adverse events of injection laryngoplasty in children.STUDY DESIGN: Case series with chart review.SETTING: Tertiary academic children's hospital.SUBJECTS AND METHODS: Patients <12 years of age with unilateral vocal fold immobility, dysphagia, and objective swallow study data were included. Primary outcome measures included perioperative adverse events and the ability to advance the diet, as defined by initiation of oral feeds or reduction in thickener following postoperative swallow study.RESULTS: The mean age of the cohort (N = 41) was 43.83 months (range, 0.5-144 months), and 46.3% of patients were <18 months old. Perioperative adverse events included increased oxygen requirement (n = 3), prolonged operating room time secondary to tenuous cardiopulmonary status (n = 2), and postoperative readmission within 30 days (n = 1). A total of 63.63% (n = 21 of 33) of patients safely advanced their diet following objective improvement on swallow study. Patients undergoing injection laryngoplasty ≤6 months of the onset of vocal fold immobility were more likely to advance their diet following surgery.CONCLUSION: Injection laryngoplasty has the potential to advance or initiate an oral diet for children with vocal fold immobility, including those in the first months of life. It is relatively free of adverse events, but certain limitations in the pediatric population must be considered. Preoperative characteristics, including timing of injection and premorbidity diet, may guide clinicians in predicting those patients most likely to advance their diet following injection laryngoplasty.

    Abstract

    OBJECTIVES/HYPOTHESIS: Over the past decade, thoracic slide tracheoplasty (TST) has become the principal operation in the management of congenital tracheal stenosis. The purpose of this report was to describe our experience with revision TST following unsuccessful prior tracheal reconstruction.STUDY DESIGN: Retrospective analysis at an academic children's hospital.METHODS: Patients undergoing TST on cardiopulmonary bypass between January 2005 and May 2014 were reviewed. Patients with a history of prior airway surgery were extracted for further analysis. Preoperative patient variables and postoperative outcomes were evaluated and compared between patients undergoing revision slide tracheoplasty (RTST) and a control group of 26 matched patients undergoing primary surgery TST.RESULTS: Twenty-six revision patients (25 referrals, one primary patient) of 162 patients reviewed over the study period met inclusion criteria. Twenty-three patients had a history of complete tracheal rings, and three patients had cartilaginous deficiency. A total of 41 airway reconstruction procedures had been performed prior to RTST. When compared to primary TST, patients undergoing RTST required fewer cardiac procedures intraoperatively, and fewer mean ventilator hours (P=.01) postoperatively. There was no significant difference in the median length of stay, requirement of >48 hours ventilation, or postoperative complications between groups. There was one nonsurgical postoperative mortality following RTST.CONCLUSIONS: Despite some differences in the postoperative management when compared to nonrevision cases, revision TST can be successfully performed after prior tracheal reconstruction with good postoperative outcomes.LEVEL OF EVIDENCE: 4.

  • Enhancing pediatric airway safety using the electronic medical record. The Laryngoscope Rameau, A. n., Wang, E. n., Saraswathula, A. n., Pageler, N. n., Perales, S. n., Sidell, D. R. 2018

    Abstract

    Difficult intubations are not uncommon in tertiary care children's hospitals, and effective documentation of the difficult airway is a fundamental element of safe airway management. The primary goal of our quality improvement initiative was to improve access to airway information via an alert and documentation system within the electronic medical record (EMR).We created a difficult airway alert within the EMR, linking common airway evaluation templates used by specialists involved in airway management. We assessed the time required for different specialists to answer an airway information questionnaire using the electronic charts of patients before and after the EMR modification. Satisfaction with the EMR modification was also surveyed.Questionnaires were administered to 12 participants before the Epic (Epic Systems Corp., Verona, WI) changes were implemented and to 19 participants after they were implemented. Each participant was asked to answer the airway data questionnaire for two patients, for a total of 24 questionnaires before the EMR changes and 38 questionnaires after the changes. Respondents averaged 7.24 minutes to complete the entire airway data questionnaire before the EMR changes and 3.16 minutes following modification (P < 0.0001). Correct airway information was more consistently collected with the modified EMR (98.6% vs 51.4%, P < 0.00001). Satisfaction surveys revealed that participants found the accessibility of airway data to be significantly improved following the EMR changes.An EMR airway alert that provides rapid access to relevant airway information critical tool during urgent and emergent events. Based on our preliminary data, further use of this instrument is expected to continue to improve patient safety and practitioner satisfaction.4. Laryngoscope, 2018.

    Abstract

    The purpose of this study was to report our clinical experience in the surgical management of patients with posterior glottic diastasis (PGD) secondary to prolonged intubation and/or laryngotracheoplasty (LTP) during childhood.We reviewed the charts of patients with a history of prolonged intubation and/or LTP who had undergone surgical correction for PGD at our institution between 2010 and 2014. We documented demographic data and pertinent information regarding medical and surgical histories. The Pediatric Voice Handicap Index (pVHI) and/or the Consensus Auditory-Perceptual Evaluation of Voice (CAPE-V) were used to assess patients both before and after undergoing treatment for voice disorders.Six patients met our inclusion criteria. With 1 exception, all patients with complete voice data demonstrated improvements in perceptual, patient-reported, and acoustic voice measures. There were no perioperative complications.Our case series demonstrates that operative intervention can lead to improved voice in carefully selected patients with PGD secondary to prolonged intubation and/or LTP during childhood. Patients exhibited postoperative improvement in loudness and vocal endurance; however, they also exhibited a degree of compromise in voice quality.

  • Pediatric Exercise Stress Laryngoscopy following Laryngotracheoplasty: A Comparative Review. Otolaryngology--head and neck surgery : official journal of American Academy of Otolaryngology-Head and Neck Surgery Sidell, D. R., Balakrishnan, K., Hart, C. K., Willging, J. P., Knecht, S. K., de Alarcon, A. 2014; 150 (6): 1056-1061

    Abstract

    Exercise-induced airway obstruction in pediatric patients is a unique phenomenon with multiple potential etiologies. An accurate diagnosis can be challenging to establish in pediatric patients because they are frequently asymptomatic at rest. Exercise stress laryngoscopy (ESL) is a modality by which pediatric patients can be evaluated under physiologic conditions that produce their symptoms. The purpose of this study was to demonstrate (1) the diagnostic effectiveness of pediatric ESL and (2) the ability of ESL to guide treatment for "normal" and post-airway reconstruction patients with exercise intolerance.Case series with chart review.Tertiary care children's hospital.Patients undergoing ESL for exercise intolerance were reviewed. Demographics, surgical history, examination findings, and management recommendations were extracted.Thirty-seven patients (average age, 13.5 years; range, 5-21 years) were included. There were 14 male and 23 female patients. Airway abnormalities became evident in 56% of patients. Of these, 24% had focal supraglottic collapse, 43% had evidence of paradoxical vocal fold motion, 24% had combined supraglottic and glottic dysfunction, and 9% had distal airway abnormalities. Overall, 18 patients had changes in management after ESL. Twelve patients in this review had histories of laryngotracheoplasty with equivocal findings on operative bronchoscopy. Of these patients, 10 (83%) received focal diagnoses after ESL.ESL is a contemporary modality by which complex patients with undiagnosed exercise intolerance can be effectively evaluated. ESL can be an important tool used to guide treatment in pediatric patients with exercise-induced dyspnea after airway reconstruction.

  • Food choking hazards in children INTERNATIONAL JOURNAL OF PEDIATRIC OTORHINOLARYNGOLOGY Sidell, D. R., Kim, I. A., Coker, T. R., Moreno, C., Shapiro, N. L. 2013; 77 (12): 1940-1946

    Abstract

    To review the literature on pediatric food choking risks, with the long-term goal of supporting legislation regulating the production, labeling, and distribution of high-risk foods.A PubMed search (Keywords: choking, obstruction, asphyxiation, foreign body, food) was conducted in July-September 2010 with publication dates ranging from 1966 to 2010.Articles related to pediatric foreign body aspiration (FBA) were selected by three independent reviewers. 1145 articles were initially identified. Abstracts were then screened utilizing a tool designed to isolate relevant pediatric choking events; this tool helped to only select abstracts which presented data on patients younger than 18 years of age who had choked on food items. Through this, a total of 72 pertinent articles were isolated (55 observational studies, 17 case reports/series).For each study, patient age, sex, foreign body location, presenting signs and symptoms, utility of radiographic studies, and type of foreign body detected in the majority of study participants were determined. A "majority" of patients for each study was predetermined arbitrarily to be 2/3 of the studied population.The majority of patients in each observational study was determined to be: male (87% of all studies) and age <5 years (95% of all studies). Aspirated foreign bodies were mostly detected in the right main bronchus foreign body (72% of all studies), and there were abnormal radiographic signs (81% of all studies) at the time of evaluation. Food-object foreign bodies were the most frequent factors associated with choking (94% of all studies).Childhood aspiration of food-objects is a significant public health issue. Although there is substantial legislation regulating non-food items that pose a choking hazard, equivalent guidelines do not exist for high-risk foods. Our study identifies and confirms several risk factors for pediatric FBA events. In doing so, it echoes the concerns and suggestions of various groups in supporting the development of legislation which may reduce the incidence of food-object aspiration.

  • Risk of Aspiration Increased by Post-swallow Residue in Infant Fiberoptic Endoscopic Evaluation of Swallowing (FEES). The Laryngoscope Chang, J., Okland, T., Johnson, A., Speiser, N., Seetharaman, A., Sidell, D. 2023

    Abstract

    To assess the risk of aspiration associated with post-swallow residue subsites in Fiberoptic Endoscopic Evaluation of Swallowing (FEES) in bottle-fed infants <1 year of age.This is a retrospective matched-pairs cohort study at an academic tertiary children's hospital. FEES and Videofluoroscopic Swallowing Study (VFSS) trials performed within the same infant <5 days apart were paired by matching bolus consistency and bottle flow rate. Positive aspiration was defined by the "or rule" in which aspiration is positive when either FEES or VFSS within a matched pair is positive.Eighty-seven FEES-VFSS matched pairs from 29 patients (16 males; mean [SD] age, 2.9 [2.8] months) were included. The rate of positive aspiration, as defined by the "or rule", was 59% (51/87). In FEES, post-swallow pyriform sinus residue was present in 16% (14/87) and anterior commissure residue 27% (31/87). Risk of positive aspiration was increased by pyriform sinus residue (odds ratio [OR] 5.4, 95% confidence interval [CI] 1.9-19.3, p < 0.01) and anterior commissure residue in FEES (OR 2.5, 95% CI 1.1-6.1, p = 0.03). In the neonate subgroup, <1 month of age, multivariate-adjusted analysis showed that anterior commissure residue had better diagnostic accuracy for aspiration than in older infants (overall 70% vs. 42%, p < 0.01; sensitivity 60% vs. 10%, p < 0.01), whereas pyriform sinus residue had worse accuracy (overall 41% vs. 70%, p = 0.02; sensitivity 13% vs. 43%, p = 0.02).This study demonstrates that pyriform sinus and anterior commissure residue during infant FEES were associated with fivefold and twofold increased risk of aspiration, respectively.Using a retrospective matched-pairs cohort, this study assesses the diagnostic accuracy of post-swallow residue in FEES for predicting aspiration.

  • Environmental Risk Factors for Pediatric Epistaxis vary by Climate Zone. The Laryngoscope Wei, E. X., Green, A., Chang, M. T., Hwang, P. H., Sidell, D. R., Qian, Z. J. 2023

    Abstract

    Prior studies have provided variable results regarding environmental risk factors for epistaxis. These studies were conducted in varying climate zones, which may explain discrepancies in results. The objective of this study is to investigate correlations between season, temperature, and humidity on frequency of pediatric epistaxis across climate zones.Children seen in the outpatient setting for epistaxis were identified from the 2007-2010 IBM MarketScan database. Climate zones were assigned according to International Energy Conservation Code (IECC) classification, where temperature zones in the United States and territories were assigned on an ordinal scale from 1 (tropical) to 8 (subarctic), and humidity zones were categorized as moist, dry, or marine. The control population was a sample of all well-child visits matched by age and county.We identified 184,846 unique children seen for epistaxis and 1,897,012 matched controls. Moderate temperature zones were associated with lower odds of epistaxis compared with the hottest and coldest zones. Humidity was associated inversely with epistaxis rates in moderate temperature zones but was not a significant predictor of epistaxis in climates with extreme heat. Additionally, summer was associated with lower odds of epistaxis compared to winter. Interestingly, however, there were significantly higher rates of cautery procedures during summer months, driven largely by increased procedures performed in clinic, as opposed to the operating room or emergency room.Environmental risk factors for epistaxis vary by climate zone. The model presented reconciles prior reports and may allow for more personalized clinical management based on regional climate.Level 3 Laryngoscope, 2023.

    Abstract

    To achieve consensus on critical steps and create an assessment tool for actual and simulated pediatric tracheostomy emergencies that incorporates human and systems factors along with tracheostomy-specific steps.A modified Delphi method was used. Using REDCap software, an instrument comprising 29 potential items was circulated to 171 tracheostomy and simulation experts. Consensus criteria were determined a priori with a goal of consolidating and ordering 15 to 25 final items. In the first round, items were rated as "keep" or "remove". In the second and third rounds, experts were asked to rate the importance of each item on a 9-point Likert scale. Items were refined in subsequent iterations based on analysis of results and respondents' comments.The response rates were 125/171 (73.1%) for the first round, 111/125 (88.8%) for the second round, and 109/125 (87.2%) for the third round. 133 comments were incorporated. Consensus (>60% participants scoring ≥8, or mean score >7.5) was reached on 22 items distributed across three domains. There were 12, 4, and 6 items in the domains of tracheostomy-specific steps, team and personnel factors, and equipment respectively.The resultant assessment tool can be used to assess both tracheostomy-specific steps as well as systems factors affecting hospital team response to simulated and clinical pediatric tracheostomy emergencies. The tool can also be used to guide debriefing discussions of both simulated and clinical emergencies, and to spur quality improvement initiatives.Level 5 Laryngoscope, 2023.

    Abstract

    Non-tuberculous mycobacterial (NTM) infection commonly manifests as subacute or chronic cervicofacial lymphadenitis in immunocompetent children. The optimal management of this pathology remains controversial.This international consensus guideline aims to understand the practice patterns for NTM cervicofacial lymphadenitis and to address the primary diagnostic and management challenges.A modified three-iterative Delphi method was used to establish expert recommendations on the diagnostic considerations, expectant or medical management, and operative considerations. The recommendations herein are derived from current expert consensus and critical review of the literature.Multinational, multi-institutional, tertiary pediatric hospitals.Consensus recommendations include diagnostic work-up, goals of treatment and management options including surgery, prolonged antibiotic therapy and observation.The recommendations formulated in this International Pediatric Otolaryngology Group (IPOG) consensus statement on the diagnosis and management of patients with NTM lymphadenitis are aimed at improving patient care and promoting future hypothesis generation.

  • Airway Characteristics of Patients With 22q11 Deletion Undergoing Pulmonary Artery Reconstruction Surgery: Retrospective Cohort Study. Pediatric critical care medicine : a journal of the Society of Critical Care Medicine and the World Federation of Pediatric Intensive and Critical Care Societies Sganga, D., Meister, K., Sidell, D. R., Wise-Faberowski, L., Shek, J., Ma, M., Martin, E., Hanley, F. L., McElhinney, D., Asija, R. 2022

    Abstract

    OBJECTIVES: We have previously shown that patients with a chromosome 22q11 microdeletion are at risk for prolonged respiratory failure after pulmonary artery reconstruction surgery compared with those with normal genotype. We sought to describe preexisting airway abnormalities in this patient population and examine relationships between airway abnormalities and outcomes.DESIGN: Single-center retrospective chart review from Society of Thoracic Surgery and Pediatric Cardiac Critical Care Consortium databases and the electronic medical record.SETTING: Lucile Packard Children's Hospital at Stanford from September 2017 to February 2019.PATIENTS: All patients undergoing pulmonary artery reconstruction surgery were considered for inclusion.INTERVENTIONS: We identified 127 patients meeting study inclusion criteria. Thirty-nine patients met specific criteria and underwent screening preoperative bronchoscopy including microdirect laryngoscopy and lower airway examination. Postoperative bronchoscopy was performed at the discretion of the intensive care team.MEASUREMENTS AND MAIN RESULTS: Airway abnormalities were detected in 25/26 of children (96%) with a chromosome 22q11 deletion who underwent preoperative bronchoscopy. Upper and lower airway pathologies were found in 19/25 (73%) and 21/25 (81%) patients, respectively, and it was common for patients to have more than one abnormality. Presence of 22q11 deletion was associated with longer duration of mechanical ventilation (9.1 vs 4.3 d; p = 0.001), use of noninvasive positive pressure support (13 vs 6 d; p = 0.001), and longer hospital stays (30 vs 14 d; p = 0.002). These outcomes were worse when compared with patients with known airway abnormalities who did not have 22q11 deletion.CONCLUSIONS: Preexisting upper and lower airway pathologies are common in patients with a chromosome 22q11 deletion who undergo pulmonary artery reconstruction surgery. Despite similar postoperative hemodynamics and outcomes as their counterparts without 22q11 deletion, 22q11 deletion is associated with more postoperative respiratory complications not entirely explained by preexisting airway abnormalities.

  • Laryngeal Ultrasound Detects Vocal Fold Immobility in Adults: A Systematic Review. Journal of ultrasound in medicine : official journal of the American Institute of Ultrasound in Medicine Su, E., Hamilton, C., Tawfik, D. S., Mariano, K., Ginsburg, S., Conlon, T., Veten, A., Fernandez, E., Wong, K., Sidell, D. R., Haileselassie, B., Pediatric Research Collaborative for Critical Ultrasound 2021

    Abstract

    Laryngeal ultrasound (US) is becoming widely accepted for assessing true vocal fold immobility (TVFI), a potential complication of laryngeal and thyroid surgery. The objective of this project is to perform a systematic review and meta-analysis of pooled evidence surrounding laryngeal US as a modality for diagnosing TVFI in adults at risk for the condition in comparison to laryngoscopy as a gold standard. Medical subject heading terms were used to search MEDLINE, Embase, Google Scholar, Web of Science, and the Cochrane Library for relevant citations from January 1, 2000, to June 30, 2020. Studies were included if they involved patients 16years and older, where laryngeal US was compared to laryngoscopy for TVFI. Studies were excluded if there were insufficient data to compute a sensitivity/specificity table after attempting to contact the authors. Case reports, and case series were also excluded. The initial search returned 1357 citations. Of these, 109 were selected for review utilizing the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Thirty citations describing 6033 patients were included in the final meta-analysis. A bivariate random effects meta-analysis was performed, revealing a pooled sensitivity for laryngeal US of 0.95 (95% confidence interval [CI] 0.88-0.98), a specificity of 0.99 (95% CI 0.97-0.99), and a diagnostic odds ratio of 1328.2 (95% CI 294.0-5996.5). The area under the curve of the hierarchical summary receiver operating characteristic curve was 0.99 (95% CI 0.98-1.00). Laryngeal US demonstrates high sensitivity and specificity for detecting VFI in the hands of clinicians directly providing care to patients.

    Abstract

    Laryngeal ultrasound is a nonirradiating, noninvasive method for assessing the upper airway in children. This systematic review and meta-analysis examine available evidence for accuracy of laryngeal ultrasound in diagnosing vocal cord immobility in infants and children after surgery and trauma affecting the vocal cords.Medical subject heading terms were used to search MEDLINE, Embase, Google Scholar, Web of Science, and the Cochrane Library for relevant citations. Publications from January 1, 2000, to June 30, 2020 were included in the search strategy. Study inclusion criteria consisted of randomized control trials and nonrandomized retrospective or prospective observational studies where vocal cord motion was evaluated by laryngeal ultrasound and compared with a reference test. Studies were excluded if there was insufficient data to compute a sensitivity/specificity table. Case reports, case series less than 10, and manuscripts not published in English were also excluded.Studies which included subjects younger than or equal to 18 years were considered for full article review.No restrictions on study settings were imposed in this systematic review.The initial search returned 1,357 citations. After de-duplication, abstract, and full review, eight citations were included in the final meta-analysis. A bivariate random-effects meta-analysis was performed, which revealed a pooled sensitivity for laryngeal ultrasound in detecting vocal cord immobility of 91% (95% CI, 83-95%), specificity of 97% (95% CI, 82-100%), diagnostic odds ratio 333.56 (95% CI, 34.00-3,248.71), positive likelihood ratio 31.58 (95% CI, 4.50-222.05), and negative likelihood ratio 0.09 (95% CI, 0.05-0.19).Laryngeal ultrasound demonstrates high sensitivity and specificity for detecting vocal cord motion in children in a wide range of clinical settings. Laryngeal ultrasound offers a low-risk imaging option for assessing vocal cord function in children compared with the current gold standard of laryngoscopy.

    Abstract

    OBJECTIVES/HYPOTHESIS: Create a competency-based assessment tool for pediatric esophagoscopy with foreign body removal.STUDY DESIGN: Blinded modified Delphi consensus process.SETTING: Tertiary care center.METHODS: A list of 25 potential items was sent via the Research Electronic Data Capture database to 66 expert surgeons who perform pediatric esophagoscopy. In the first round, items were rated as "keep" or "remove" and comments were incorporated. In the second round, experts rated the importance of each item on a seven-point Likert scale. Consensus was determined with a goal of 7 to 25 final items.RESULTS: The response rate was 38/64 (59.4%) in the first round and returned questionnaires were 100% complete. Experts wanted to "keep" all items and 172 comments were incorporated. Twenty-four task-specific and 7 previously-validated global rating items were distributed in the second round, and the response rate was 53/64 (82.8%) with questionnaires returned 97.5% complete. Of the task-specific items, 9 reached consensus, 7 were near consensus, and 8 did not achieve consensus. For global rating items that were previously validated, 6 reached consensus and 1 was near consensus.CONCLUSIONS: It is possible to reach consensus about the important steps involved in rigid esophagoscopy with foreign body removal using a modified Delphi consensus technique. These items can now be considered when evaluating trainees during this procedure. This tool may allow trainees to focus on important steps of the procedure and help training programs standardize how trainees are evaluated.LEVEL OF EVIDENCE: 5. Laryngoscope, 2020.

  • The Difficult Airway and Aerosol-Generating Procedures in COVID-19: Timeless Principles for Uncertain Times. Otolaryngology--head and neck surgery : official journal of American Academy of Otolaryngology-Head and Neck Surgery Smith, J. D., Chen, M. M., Balakrishnan, K., Sidell, D. R., di Stadio, A., Schechtman, S. A., Brody, R. M., Kupfer, R. A., Rassekh, C. H., Brenner, M. J. 2020: 194599820936615

    Abstract

    The impact of the COVID-19 pandemic on otolaryngology practice is nowhere more evident than in acute airway management. Considerations of preventing SARS-CoV-2 transmission, conserving personal protective equipment, and prioritizing care delivery based on acuity have dictated clinical decision making in the acute phase of the pandemic. With transition to a more chronic state of pandemic, heightened vigilance is necessary to recognize how deferral of care in patients with tenuous airways and COVID-19 infection may lead to acute airway compromise. Furthermore, it is critical to respect the continuing importance of flexible laryngoscopy in diagnosis. Safely managing airways during the pandemic requires thoughtful multidisciplinary planning. Teams should consider trade-offs among aerosol-generating procedures involving direct laryngoscopy, supraglottic airway use, fiberoptic intubation, and tracheostomy. We share clinical cases that illustrate enduring principles of acute airway management. As algorithms evolve, time-honored approaches for diagnosis and management of acute airway pathology remain essential in ensuring patient safety.

  • Tracheostomy in Infants in the Neonatal Intensive Care Unit. NeoReviews Chang, J., Sidell, D. R. 2020; 21 (5): e323–e334

    Abstract

    Approximately half of all pediatric tracheostomies are performed in infants younger than 1 year. Most tracheostomies in patients in the NICU are performed in cases of chronic respiratory failure requiring prolonged mechanical ventilation or upper airway obstruction. With improvements in ventilation and management of long-term intubation, indications for tracheostomy and perioperative management in this population continue to evolve. Evidence-based protocols to guide routine postoperative care, prevent and manage tracheostomy emergencies including accidental decannulation and tube obstruction, and attempt elective decannulation are sparse. Clinician awareness of safe tracheostomy practices and larger, prospective studies in infants are needed to improve clinical care of this vulnerable population.

  • Pediatric tracheostomy practice patterns. International journal of pediatric otorhinolaryngology Sioshansi, P. C., Balakrishnan, K., Messner, A., Sidell, D. 2020; 133: 109982

    Abstract

    OBJECTIVE: Despite recent guidelines and the frequency of pediatric tracheostomy, surgical techniques and perioperative management are variable. We aim to describe the post-operative practice patterns following tracheostomy in children.METHODS: An electronic cross-sectional survey was distributed to American Society of Pediatric Otolaryngologists (ASPO) members in academic and private practice settings. Responses were collected anonymously and analyzed by percentages of respondents who employ specific management strategies. Statistical analysis of response distributions performed using the Z test of proportions for binary questions and the Mantel-Haenszel chi-square test for questions with more than two options. For questions with ordered categorical responses, Cuzick's nonparametric test of trend was used.RESULTS: One-hundred twenty-four responses were received (22.3%). Most respondents were fellowship trained and practiced in academic medical centers. A greater number of tracheostomies were performed by respondents practicing in the Midwest region (p=0.042). There was no variability in the number of tracheostomies performed based on practitioner age, hospital setting, or fellowship training. The majority perform stoma maturation and/or stay suture techniques intraoperatively and send patients to the intensive care unit postoperatively. The routine use of postoperative paralysis was reported by a minority of respondents and 50% reported the use of sedation. There was a roughly-even distribution of respondents who reported postoperative immobilization, mobilization to a chair, and ambulation respectively. Routine; postoperative airway evaluations were reported by 35% of respondents. Clinic follow-up was; variable.CONCLUSION: These results demonstrate ongoing variability in the postoperative management strategies following tracheostomy in children and highlight areas for further study.

  • Prospective Evaluation of the Safety and Efficacy of THRIVE for Children Undergoing Airway Evaluation. Pediatric quality & safety Okland, T. S., Liu, G. S., Caruso, T. J., Sidell, D. R. 2020; 5 (5): e348

    Abstract

    Transnasal Humidified Rapid-Insufflation Ventilatory Exchange (THRIVE) is a humidified high-flow nasal cannula capable of extending apneic time. Although THRIVE is assumed to stent upper airway soft tissues, this has not been objectively evaluated. Also, there are no prior studies providing safety and efficacy data for those patients undergoing upper airway evaluation using THRIVE.This report is a prospective study of the safety and efficacy of THRIVE in pediatric patients younger than 18 years old undergoing drug-induced sleep endoscopy. We positioned a flexible laryngoscope to view the larynx, and photographs were taken with no THRIVE flow (control) and with THRIVE flow at 10 and 20 liters per minute (LPM). Upper airway patency was measured using epiglottis to posterior pharynx distance, laryngeal inlet area, and modified Cormack-Lehane score at the trialed parameters. Vomiting and aspiration were our primary safety endpoints.Eleven patients (6 women) with a mean age of 5.3 ± 2.1 years (2-8 years; SD, 2.05) were enrolled. Measurements of upper airway patency showed a significant THRIVE flow-associated increase in epiglottis to posterior pharynx distance (105 ± 54 at 10 L/min and 199 ± 67 at 20 L/min; P = 0.007) and nonsignificant increase of laryngeal inlet area (206 ± 148 at 10 L/min and 361 ± 190 at 20 L/min; P = 0.07). Cormack-Lehane score improved significantly at higher THRIVE volumes (P = 0.006).THRIVE appears to safely improve upper airway patency during sleep endoscopy in the pediatric patient. In this study, we objectively document the flow-dependent increase in laryngeal patency associated with THRIVE.

    Abstract

    To confirm the standard of care pertaining to postoperative mobilization practices following initial tracheostomy, to establish face validity of novel early mobilization tools, and to conduct a safety and feasibility pilot study.Multi-institutional survey and prospective cohort study.Experts at our tertiary-care children's hospital developed an Early Pediatric Mobility Pathway for tracheostomy patients utilizing a novel risk-assessment tool. Surveys were distributed to professional colleagues in similar children's hospitals to establish face validity and incorporate respondent feedback. Additional surveys were disseminated to tertiary-care children's hospitals across the country to establish the current standard of care, and a pilot study was conducted.Seventy-seven percent of respondents from tertiary hospitals across the country confirmed the standard of care to defer mobilization until the first trach change. Greater than 83% of the respondents used to establish face validity of the tools agreed with the clinical components and scoring structure. The safety and feasibility of early mobilization prior to initial trach change was confirmed with a pilot of 10 pediatric patients without any adverse events.Mobilization of pediatric patients prior to initial trach change is feasible and can be safe when risk factors are assessed by a multidisciplinary team.4 Laryngoscope, 2020.

    Abstract

    OBJECTIVES/HYPOTHESIS: Create a competency-based assessment tool for pediatric tracheotomy.STUDY DESIGN: Blinded, modified, Delphi consensus process.METHODS: Using the REDCap database, a list of 31 potential items was circulated to 65 expert surgeons who perform pediatric tracheotomy. In the first round, items were rated as "keep" or "remove," and comments were incorporated. In the second round, experts were asked to rate the importance of each item on a seven-point Likert scale. Consensus criteria were determined a priori with a goal of 7 to 25 final items.RESULTS: The first round achieved a response rate of 39/65 (60.0%), and returned questionnaires were 99.5% complete. All items were rated as "keep," and 137 comments were incorporated. In the second round, 30 task-specific and seven previously validated global rating items were distributed, and the response rate was 44/65 (67.7%), with returned questionnaires being 99.3% complete. Of the Task-Specific Items, 13 reached consensus, 10 were near consensus, and 7 did not achieve consensus. For the 7 previously validated global rating items, 5 reached consensus and two were near consensus.CONCLUSIONS: It is feasible to reach consensus on the important steps involved in pediatric tracheotomy using a modified Delphi consensus process. These items can now be considered to create a competency-based assessment tool for pediatric tracheotomy. Such a tool will hopefully allow trainees to focus on the important aspects of this procedure and help teaching programs standardize how they evaluate trainees during this procedure.LEVEL OF EVIDENCE: 5 Laryngoscope, 2019.

    Abstract

    OBJECTIVES: Static Endoscopic Evaluation of Swallowing (SEES) has been demonstrated to have a strong correlation with the Videofluoroscopic Swallow Study (VFSS) in adults. In children, Fiberoptic Endoscopic Evaluations of Swallow (FEES) are frequently performed to avoid repeated VFSS; however, a subset of the population does not tolerate FEES. The purpose of this study was to evaluate the utility of a modified SEES in children.METHODS: Charts of 50 consecutive patients who underwent FEES evaluations were reviewed. Patients age 3 months to 12years undergoing SEES, FEES, and VFSS were extracted. We compared a binary assessment of outcome on SEES versus VFSS as the diagnostic standard to report characteristics, including sensitivity, specificity, and positive and negative predicted value.RESULTS: A total of 36 patients met all inclusion criteria (mean age 2.8years). Using the VFSS as the diagnostic standard, residue seen on SEES had a sensitivity of 80.0%, specificity of 85.7%, a positive predictive value of 88.9%, and a negative predictive value of 75.0% for predicting deep penetration or aspiration.CONCLUSION: SEES may be helpful for developing an initial diagnostic impression and may serve as a platform for patient and caregiver counseling. In children who are unable to cooperate with FEES, SEES may provide clinical insight in predicting an abnormal swallow study; however, a normal SEES was less reliable in predicting a safe swallow on subsequent VFSS in this patient population.LEVEL OF EVIDENCE: 4 Laryngoscope, 2019.

    Abstract

    Children with congenital heart disease may present with severe airway compression prior to any surgical procedure or may develop airway compression following their surgical procedure. This combination of congenital heart defect and airway compression poses a significant management challenge. The purpose of this study was to review our experience with the Lecompte procedure for relief of severe airway compression.This was a retrospective review of ten patients who underwent a Lecompte procedure for relief of severe airway compression over the past nine years (2010-2018). Three patients with absent pulmonary valve syndrome presented with severe symptoms prior to any surgical procedure. Seven patients presented with symptoms of airway compression following repair of their congenital heart defects (one with absent pulmonary valve syndrome, three patients had repair of pulmonary atresia with ventricular septal defect, and three patients had undergone aortic arch surgery). The median age at presentation was two years (range: one day to seven years).The ten patients underwent a Lecompte procedure without any significant complications or operative mortality. The median interval between the surgical procedure and extubation was 9.5 days. No patients have required any further interventions for relief of airway obstruction.The Lecompte procedure is a surgical option for young children who present with severe airway compression. The patients in this series responded well to the Lecompte procedure as evidenced by clinical relief of airway compression.

    Abstract

    Laryngotracheal disruption in children is rare but life-threatening, and endolaryngeal injuries may go overlooked. We present the case of a 10-year-old boy who sustained near-complete laryngotracheal separation, multiple laryngeal fractures, and arytenoid and vocal fold avulsion following blunt cervical trauma. These injuries were not identified radiographically and only became apparent intraoperatively. Following surgical repair, the patient was successfully decannulated, eating a normal diet, and had a serviceable speaking voice within 2 months. In children, the diagnosis of severe endolaryngeal injuries may be elusive and therefore require high degree of clinical suspicion. Surgical success requires accurate diagnosis and prompt intervention.

    Abstract

    Children with tetralogy of Fallot, pulmonary atresia, and major aortopulmonary collaterals (TOF/MAPCAs) are at risk for post-operative respiratory complications after undergoing unifocalisation surgery. Thus, we assessed and further defined the incidence of airway abnormalities in our series of over 500 children with TOF/MAPCAs as determined by direct laryngoscopy, chest computed tomography (CT), and/or bronchoscopy.The medical records of all patients with TOF/MAPCAs who underwent unifocalisation or pulmonary artery reconstruction surgery from March, 2002 to June, 2018 were reviewed. Anaesthesia records, peri-operative bronchoscopy, and/or chest CT reports were reviewed to assess for diagnoses of abnormal or difficult airway. Associations between chromosomal anomalies and airway abnormalities - difficult anaesthetic airway, bronchoscopy, and/or CT findings - were defined.Of the 564 patients with TOF/MAPCAs who underwent unifocalisation or pulmonary artery reconstruction surgery at our institution, 211 (37%) had a documented chromosome 22q11 microdeletion and 28 (5%) had a difficult airway/intubation reported at the time of surgery. Chest CT and/or peri-operative bronchoscopy were performed in 234 (41%) of these patients. Abnormalities related to malacia or compression were common. In total 35 patients had both CT and bronchoscopy within 3 months of each other, with concordant findings in 32 (91%) and partially concordant findings in the other 3.This is the largest series of detailed airway findings (direct laryngoscopy, CT, and bronchoscopy) in TOF/MAPCAS patients. Although these findings are specific to an at-risk population for airway abnormalities, they support the utility of CT and /or bronchoscopy in detecting airway abnormalities in patients with TOF/MAPCAs.

    Abstract

    To provide recommendations to otolaryngologists and allied physicians for the comprehensive management of young infants who present with signs or symptoms of choanal atresia.A two-iterative delphi method questionnaire was used to establish expert recommendations by the members of the International Otolaryngology Group (IPOG), on the diagnostic, intra-operative, post-operative and revision surgery considerations.Twenty-eight members completed the survey, in 22 tertiary-care center departments representing 8 countries. The main consensual recommendations were: nasal endoscopy or fiberscopy and CT imaging are recommended for diagnosis; unilateral choanal atresia repair should be delayed after at least age 6 months whenever possible; transnasal endoscopic repair is the preferred technique; long term follow-up is recommended (minimum one year) using nasal nasofiberscopy or rigid endoscopy, without systematic imaging.Choanal atresia care consensus recommendations are aimed at improving patient-centered care in neonates, infants and children with choanal atresia.

  • Outcomes After Initial Unifocalization to a Shunt in Complex Tetralogy of Fallot with MAPCAs. The Annals of thoracic surgery Bauser-Heaton, H. n., Ma, M. n., Wise-Faberowski, L. n., Asija, R. n., Shek, J. n., Zhang, Y. n., Peng, L. F., Sidell, D. R., Hanley, F. L., McElhinney, D. B. 2019

    Abstract

    Our approach to tetralogy of Fallot (TOF) with pulmonary atresia and major aortopulmonary collateral arteries (MAPCAs) emphasizes early single-stage unifocalization and intracardiac repair. However, a subset of patients with small native pulmonary arteries (PAs) and MAPCAs undergo unifocalization to a shunt rather than simultaneous intracardiac repair.Patients with TOF/MAPCAs who underwent unifocalization to a systemic-to-PA shunt by a single surgeon were reviewed. The decision to perform simultaneous intracardiac repair was based on an intraoperative flow study or empirical assessment of PA and MAPCA size.From 11/01-12/17, 57 patients with TOF/MAPCAs underwent unifocalization to a shunt at a median age of 6.9 months. Genetic abnormalities were documented in 60% of patients, including a chromosome 22q11 deletion in 25 and Alagille syndrome in 8. Twenty patients (35%) had undergone prior surgery elsewhere (n=16) and/or at our center (n=7). During a median follow-up of 5.4 years, 9 patients had additional surgery to revise the PA reconstruction before complete repair, and 38 patients underwent complete repair. Survival was 74±6% 5 years after unifocalization. At follow-up, the median PA:aortic systolic pressure ratio was 0.36 and was >0.50 in 2 patients.In patients with the smallest MAPCAs and PAs, single-stage unifocalization to a shunt followed by intracardiac repair yields an excellent outcome in most cases.

    Abstract

    OBJECTIVE: To describe the longitudinal association between disease severity, time established in clinical treatment, and caregiver burden in a community-based patient population diagnosed with pediatric acute-onset neuropsychiatric syndrome (PANS).METHODS: The study included an observational longitudinal cohort design, with Caregiver Burden Inventories (CBIs) collected between April 2013 and November 2016 at the Stanford PANS multidisciplinary clinic. Inclusion criteria for this study were as follows: pediatric patients meeting strict PANS/pediatric autoimmune neuropsychiatric disorders associated with streptococcal infections (PANDAS) diagnostic criteria (n = 187), having a caregiver fill out at least 1 complete CBI during a disease flare (n = 114); and having family who lives locally (n = 97). For longitudinal analyses, only patients whose caregiver had filled out 2 or more CBIs (n = 94 with 892 CBIs) were included. In the study sample, most primary caregivers were mothers (69 [71.1%] of 97), the majority of PANS patients were male (58 [59.8%] of 97), and mean age at PANS onset was 8.8 years.RESULTS: In a patient's first flare tracked by the clinic, 50% of caregivers exceeded the caregiver burden score threshold used to determine respite need in care receiver adult populations. Longitudinally, flares, compared with quiescence, predicted increases in mean CBI score (6.6 points; 95% CI, 5.1 to 8.0). Each year established in clinic predicted decreased CBI score (-3.5 points per year; 95% CI, -2.3 to -4.6). Also, shorter time between PANS onset and entry into the multidisciplinary clinic predicted greater improvement in mean CBI score over time (0.7 points per year squared; 95% CI, 0.1 to 1.3). Time between PANS onset and treatment with antibiotics or immunomodulation did not moderate the relationship between CBI score and time in clinic.CONCLUSIONS: PANS caregivers suffer high caregiver burden. Neuropsychiatric disease severity predicts increased caregiver burden. Caregiver burden tends to decrease over time in a group of patients undergoing clinical treatment at a specialty PANS clinic. This decrease could be independent of clinical treatment.

  • Deletion of 22q11 chromosome is associated with postoperative morbidity after unifocalisation surgery. Cardiology in the young Koth, A., Sidell, D., Bauser-Heaton, H., Wise-Faberowski, L., Hanley, F. L., McElhinney, D. B., Asija, R. 2018: 1–4

    Abstract

    BACKGROUND: A 22q11 chromosome deletion is common in patients with tetralogy of Fallot, pulmonary atresia, and major aortopulmonary collaterals. We sought to determine whether 22q11 chromosome deletion is associated with increased postoperative morbidity after unifocalisation surgery.METHODS: We included all patients with this diagnosis undergoing primary or revision unifocalisation ± ventricular septal defect closure at our institution from 2008 to 2016, and we excluded patients with unknown 22q11 status. Demographic and surgical data were collected. We compared outcomes between those with 22q11 chromosome deletion and those without using non-parametric analysis.RESULTS: We included 180 patients, 41% of whom were documented to have a chromosome 22q11 deletion. Complete unifocalisation was performed in all patients, and intracardiac repair was performed with similar frequency regardless of 22q11 chromosome status. Duration of mechanical ventilation was longer in 22q11 deletion patients. This difference remained significant after adjustment for delayed sternal closure and/or intracardiac repair. Duration of ICU stay was longer in patients with 22q11 deletion, although no longer significant when adjusted for delayed sternal closure and intracardiac repair. Finally, length of hospital stay was longer in 22q11-deleted patients, but this difference was not significant on unadjusted or adjusted analysis.CONCLUSION: Children with tetralogy of Fallot, pulmonary atresia, and major aortopulmonary collaterals and 22q11 deletion are at risk for greater prolonged mechanical ventilation after unifocalisation surgery. Careful attention should be given to the co-morbidities of this population in the perioperative period to mitigate risks that may complicate the postoperative course.

M., Sakarovitch, C., Sidell, D. R., Schultz, L. M., Freccero, A., Rizzuto, S., Hanley, F. L., Asija, R. 2018: 1–4

    Abstract

    BACKGROUND: Patients with tetralogy of Fallot, pulmonary atresia, and major aortopulmonary collaterals are at risk for prolonged hospitalisation after unifocalisation. Feeding problems after congenital heart surgery are associated with longer hospital stay. We sought to determine the impact of baseline, intra-operative, and postoperative factors on the need for feeding tube use at the time of discharge.METHODS: We included patients with the aforementioned diagnosis undergoing unifocalisation from ages 3 months to 4 years from 2010 to 2016. We excluded patients with a pre-existing feeding tube. Patients discharged with an enteric tube were included in the feeding tube group. We compared the feeding tube group with the non-feeding-tube group by univariable and multi-variable logistic regression.RESULTS: Of the 56 patients studied, 41% used tube feeding. Median age and weight z-score were similar in the two groups. A chromosome 22q11 deletion was associated with the need for a feeding tube (22q11 deletion in 39% versus 15%, p=0.05). Median cardiopulmonary bypass time in the feeding tube group was longer (335 versus 244 minutes, p=0.04). Prolonged duration of mechanical ventilation was associated with feeding tube use (48 versus 3%, p=0.001). On multi-variable analysis, prolonged mechanical ventilation was associated with feeding tube use (odds ratio 10.2, 95% confidence intervals 1.6; 63.8).CONCLUSION: Among patients with tetralogy of Fallot, pulmonary atresia, and major aortopulmonary collaterals who were feeding by mouth before surgery, prolonged mechanical ventilation after unifocalisation surgery was associated with feeding tube use at discharge. Anticipation of feeding problems in this population and earlier feeding tube placement may reduce hospital length of stay.

    Abstract

    Injury to the phrenic nerves may occur during surgery for pulmonary atresia with ventricular septal defect and major aortopulmonary collateral arteries (PA-VSD and MAPCAs). These patients may develop respiratory failure and require diaphragm plication. The purpose of this study was to evaluate the impact of phrenic nerve palsy on recovery following surgery for PA-VSD and MAPCAs. Between 2007 and 2016, approximately 500 patients underwent surgery for PA-VSD and MAPCAs at our institution. Twenty-four patients (4.8%) subsequently had evidence of new phrenic nerve palsy. Sixteen patients were undergoing their first surgical procedure, whereas 8 were undergoing reoperations. All 24 patients underwent diaphragm plication. A cohort of matched controls was identified based on identical diagnosis and procedures but did not sustain a phrenic nerve palsy. Eighteen of the 24 patients (75%) had clinical improvement following diaphragm plication as evidenced by the ability to undergo successful extubation (5±2 days), transition out of the intensive care unit (32±16 days), and discharge from the hospital (42±19 days). In contrast, there were 6 patients (25%) who did not demonstrate a temporal improvement following diaphragm plication, as evidenced by intervals of 61±38, 106±45, and 108±46 days, respectively (P<0.05 for all 3 comparisons). The 6 patients who failed to improve following diaphragm plication had a significantly greater number of comorbidities compared to the 18 patients who demonstrated improvement (2.2 vs 0.6 per patient, P<0.05). When compared with the control group, patients who improved following diaphragm plication spent an additional 22 days and patients who failed to improve an additional 90 days in the hospital. The data demonstrate a bifurcation of clinical outcome in patients undergoing diaphragm plication following surgery for PA-VSD and MAPCAs. This bifurcation appears to be linked to the presence or absence of other comorbidities.

  • "Split to save": Accessing mandibular lesions using sagittal split osteotomy with virtual surgical planning ENT-EAR NOSE & THROAT JOURNAL Liu, S., Sidell, D., Huon, L., Torre, C. 2018; 97 (3): 91–96

    Abstract

    Large, benign intramandibular lesions are frequently removed by resection followed by extensive free tissue transfer or delayed bone grafting. We outline a protocol to remove benign mandibular lesions using sagittal split osteotomy (SSO) with virtual surgical planning (VSP) to mitigate risks involved with this effective, tissue-saving approach. Patients with benign mandibular lesions accessed by SSO with VSP during 2014 were included in this study. Computed tomographic data were imported into VSP software. Using VSP, the exact locations of mandibular lesions and the inferior alveolar nerve canal were delineated. SSO was designed virtually and provided surgeons exact measurements to gain access to lesions and to avoid vital structures intraoperatively. SSO with VSP preserved the cortical mandibular bone and the inferior alveolar neurovascular bundle in 3 patients with benign mandibular lesions. Twelve months after surgery, no patient had pathologic fracture, prolonged paresthesia (except for the patient who required inferior alveolar nerve resection), or malocclusion. No patient required bone grafting. There were no functional or aesthetic jaw deficits. SSO is an effective approach to access intramandibular lesions. The technique does not result in loss of mandibular bone, and patients return to full masticatory function compared with those who require resection and reconstruction. VSP may mitigate technical challenges associated with SSO.

    Abstract

    Children with Tetralogy of Fallot, Pulmonary Atresia, and Major Aortopulmonary Collaterals (TOF/PA/MAPCAs) undergoing unifocalization surgery are at risk for developing more postoperative respiratory complications than children undergoing other types of congenital heart surgery. Bronchoscopy is used in the perioperative period for diagnostic and therapeutic purposes. In this study, we describe bronchoscopic findings and identify factors associated with selection for bronchoscopy.Retrospective case-control.All patients with TOF/PA/MAPCAs who underwent unifocalization surgery from September 2005 through March 2016 were included. Patients who underwent bronchoscopy in the perioperative period were compared to a randomly selected cohort of 172 control patients who underwent unifocalization without bronchoscopy during the study period.Forty-three children underwent perioperative bronchoscopy at a median of 9 days postoperatively. Baseline demographics were similar in bronchoscopy patients and controls. Patients who underwent bronchoscopy were more likely to have a chromosome 22q11 deletion and were more likely have undergone unifocalization surgery without intracardiac repair. These patients had a longer duration of mechanical ventilation, ICU duration, and length of hospitalization. Abnormalities were detected on bronchoscopy in 35 patients (81%), and 20 (35%) of bronchoscopy patients underwent a postoperative intervention related to abnormalities identified on bronchoscopy.Bronchoscopy is a useful therapeutic and diagnostic instrument for children undergoing unifocalization surgery, capable of identifying abnormalities leading to an additional intervention in over one third of patients. Special attention should be given to children with a 22q11 deletion to expedite diagnosis and intervention for possible airway complications.

  • Palatal Petechiae in the Absence of Group A Streptococcus in Pediatric Patients with Acute-Onset Neuropsychiatric Deterioration: A Cohort Study. Journal of child and adolescent psychopharmacology Mahony, T., Sidell, D., Gans, H., Cooperstock, M., Brown, K., Cheung, J. M., Farhadian, B., Gustafson, M., Thienemann, M., Frankovich, J. 2017

    Abstract

    Palatal petechiae are 95% specific for streptococcal pharyngitis. Despite this, and despite prior research demonstrating that Group A Streptococcus (GAS) is a common antecedent to pediatric acute-onset neuropsychiatric syndrome (PANS) episodes, we anecdotally observed a low rate of documented GAS in patients with PANS and palatal petechiae. This retrospective chart review was conducted to formally report the rate of palatal petechiae and concurrent GAS in a cohort of patients with PANS and investigate other etiologic factors.The clinical notes of 112 patients seen at the Stanford PANS Clinic who met PANS research criteria were reviewed for mention of palatal petechiae. The medical records of patients who demonstrated palatal petechiae on physical examination were reviewed for signs of infection, a clinical history of trauma, and laboratory results that could indicate other causes of petechiae.Twenty-three patients had documented palatal petechiae on physical examination (ages 5-16, 13/23 [57%] male). Fifteen patients had a rapid GAS test and GAS culture in the Stanford PANS clinic, all with negative results. Evidence of recent GAS infection was found in 8/23 (32%) patients (elevated GAS titers [n = 6] or documentation of a positive rapid GAS test at another facility [n = 2]), one of whom also had potential herpes simplex virus (HSV) infection. One patient had potential HSV infection and recent palatal trauma. No patients had thrombocytopenia. 14/23 (61%) of patients with palatal petechiae had no discernable cause of petechiae. 10/19 (53%) of patients had antihistone antibodies.Despite the established relationship between palatal petechiae and GAS, no patient with palatal petechiae in our clinic tested positive for GAS and only 32% had evidence of recent GAS. Most did not have an identifiable cause for the palatal lesions. This finding suggests the potential for alternative causes of palatal petechiae or undetectable GAS in our patient population. The high prevalence of palatal petechiae without GAS infection suggests that the pathogenesis of PANS is multifactorial and may involve disruption or inflammation of the microvasculature. Additional research is needed to further elucidate these findings.

    Abstract

    Children with bilateral true vocal fold immobility (BTVFI) may present with significant airway distress necessitating tracheostomy. The objective of this study was to review our preliminary experience with the anterior-posterior cricoid split (APCS), an endoscopic intervention used as an alternative to tracheostomy in children with BTVFI.Multicenter review.A review of patients undergoing endoscopic APCS for BTVFI at four institutions was performed. Patients were evaluated for the ability to ventilate without the requirement for tracheostomy or reintubation. Additional data extracted included the duration of intubation following APCS, the requirement for additional procedures, and demographics. Surgical success was defined as the ability to avoid tracheostomy and to cap or decannulate without respiratory symptoms if a tracheostomy was present prior to APCS.Nineteen APCS procedures were performed between October 2010 and June 2016. There were 12 male patients, the mean age at APCS was 4.7 months. BTVFI was primarily idiopathic (58%) and associated with other comorbidities (74%). All patients were candidates for tracheostomy prior to APCS. Fourteen patients (74%) were considered surgical successes. Of the unsuccessful patients, three (66%) required tracheostomy following APCS, and one was treated with a posterior cartilage graft. There was one nonsurgical mortality greater than 2 months after APCS and thought to be unrelated to the airway.Endoscopic APCS appears to be a safe and effective intervention for pediatric BTVFI. Under the correct circumstances, this can be performed as a single procedure, obviating tracheostomy. Further study is warranted.4 Laryngoscope, 2017.

    Abstract

    Accumulating evidence supports a role for inflammation in psychiatric illness, and the onset or exacerbation of psychiatric symptoms may follow non-CNS infections. Here, we provide the first detailed description of obsessive-compulsive and related psychiatric symptoms arising concurrently with sinusitis.We reviewed the charts of 150 consecutive patients evaluated in our Pediatric Acute-onset Neuropsychiatric Syndromes clinic for documented sinusitis as defined by the American Academy of Pediatrics guidelines. Sinusitis treatments, sinonasal imaging, and neuropsychiatric symptoms before, during, and after sinusitis onset were noted. Patients were included in the final review if they had a clear diagnosis of isolated sinusitis (without concurrent illness and/or immunodeficiency), and were evaluated during an episode of sinusitis.10/150 (6.6%) patients had isolated sinusitis at the time of their neuropsychiatric deterioration. Eight patients received antibiotics to treat sinusitis, three of whom also received sinus surgery. Neuropsychiatric symptoms improved in all eight patients concurrent with resolution of sinusitis per parent report and clinician assessment. One patient did not follow through with recommended sinus surgery or antibiotics and her psychiatric symptoms persisted. One patient was lost to follow-up.Improvement of psychiatric symptoms correlated with resolution of sinus disease in this retrospective study. Identification, treatment, and resolution of underlying infections, including sinusitis, may have the potential to change the trajectory of some neuropsychiatric illnesses. Randomized clinical trials are needed.

    Abstract

    In contrast to more common nasal and cervical lesions, the frontotemporal pit is a rarely encountered lesion that is often associated with a dermoid and may track intracranially. Due to delays in diagnosis, the propensity to spread intracranially, and the risk of infection, awareness of these lesions and appropriate diagnosis and management are important. The authors present 2 cases of frontotemporal pits from a single institution. Epidemiology, presentation, and management recommendations are discussed.

    Abstract

    A 14-year-old male presented with lower lip numbness and a slowly enlarging mandibular mass. Computed tomography demonstrated an expansile lesion centered in the marrow space of the left mandibular body, extending along the course of the inferior alveolar nerve (IAN), and expanding the mental foramen. Preoperative diagnosis was consistent with an IAN schwannoma. Surgical planning was performed using PROPLAN CMF software. The lesion was approached via a sagittal split osteotomy and excised en bloc with the IAN. Final pathology demonstrated a capillary hemangioma originating from the inferior alveolar nerve. Based on a detailed PubMed search, this is the first capillary hemangioma of the inferior alveolar nerve reported in the literature.NA Laryngoscope, 2016.

    Abstract

    High dose antivirals have been shown to cause hearing loss when applied via the intratympanic route. The aim of this study was to determine if a combination therapy using dexamethasone (DXA) with either Cidofovir (CDV) or Ganciclovir (GCV), in solution or in PLGA-PEG-PLGA (PPP) hydrogel, is innocuous to the inner ear.Cytomegalovirus (CMV)-free guinea pigs were separated into four principal study groups and treated via intratympanic injection (IT) of CDV/DXA solution, CDV/DXA Hydrogel, GCV/DXA solution and GCV/DXA hydrogel. Hearing thresholds were evaluated with pretreatment ABR and post injection weekly ABRs for a total follow up of 28 days. Temporal bone tissue was harvested and stained with Hematoxylin and Eosin for histologic analysis.ABR analysis revealed that GCV/DXA in solution and in hydrogel led to a mild hearing loss at days 7-21 but returned to baseline by day 28 When administered via PPP hydrogel, CDV/DXA demonstrated mild persistent hearing loss at 32kHz at 28 days. An inflammatory response was identified in the cochlear specimen of the CDV/DXA/PPP hydrogel group, in concert with mild hearing loss, at days 21 and 28.Results of this study support the safe intratympanic use of higher concentrations of antivirals when combined with DXA, both in solution and when applied via PPP hydrogel.

    Abstract

    Sialorrhea is problematic for neurologically impaired children, and botulinum toxin A salivary gland injection has been reported as effective in reducing sialorrhea. This article assesses the success and safety of ultrasound-guided weight-based botulinum toxin A injection for the management of sialorrhea in children.A total of 111 patients (63 males; 48 females; average age 7 years) with refractory sialorrhea were treated with ultrasound-guided botulinum toxin type A salivary gland injections (144 procedures) from July 1, 2004, to July 1, 2014, using a single weight-based protocol. Patient history, procedural records, and clinical follow-up documents were retrospectively reviewed. Clinical data were compared with reported effectiveness and complications using odds ratios.A total of 144 procedures were performed in 111 patients with refractory sialorrhea. Cerebral palsy was the most common underlying etiology for sialorrhea (29%), whereas others included encephalopathy (5%), anoxic brain injury (4%), and a variety of chromosomal anomalies (5%). There was a 100% technical success rate. Overall treatment effectiveness was 68%. Repeat injections were not associated with increased clinical success. No procedure-related deaths or major complications were identified; the minor complication rate was less than 2%.The protocol used for ultrasound-guided injection of botulinum toxin A proved to be safe and effective in children suffering from sialorrhea. Image guidance technique may lead to a reduction in rates of adverse events reported in other series. Subsequent procedures do not improve upon initial efficacy.

Patient history, procedural records, and clinical follow-up documents were retrospectively reviewed. Clinical data were compared with reported effectiveness and complications using odds ratios.A total of 144 procedures were performed in 111 patients with refractory sialorrhea. Cerebral palsy was the most common underlying etiology for sialorrhea (29%), whereas others included encephalopathy (5%), anoxic brain injury (4%), and a variety of chromosomal anomalies (5%). There was a 100% technical success rate. Overall treatment effectiveness was 68%. Repeat injections were not associated with increased clinical success. No procedure-related deaths or major complications were identified; the minor complication rate was less than 2%.The protocol used for ultrasound-guided injection of botulinum toxin A proved to be safe and effective in children suffering from sialorrhea. Image guidance technique may lead to a reduction in rates of adverse events reported in other series. Subsequent procedures do not improve upon initial efficacy.

  • Outcomes and Resource Utilization of Endoscopic Mass-Closure Technique for Laryngeal Clefts OTOLARYNGOLOGY-HEAD AND NECK SURGERY Balakrishnan, K., Cheng, E., de Alarcon, A., Sidell, D. R., Hart, C. K., Rutter, M. J. 2015; 153 (1): 119-123

    Abstract

    To compare resource utilization and clinical outcomes between endoscopic mass-closure and open techniques for laryngeal cleft repair.Case series with chart review.Tertiary academic children's hospital.Pediatric patients undergoing repair for Benjamin-Inglis type 1-3 laryngeal clefts over a 15-year period. All 20 patients undergoing endoscopic repair were included. Eight control patients undergoing open repair were selected using matching by age and cleft type. Demographic, clinical, and resource utilization data were collected.Twenty-eight patients were included (20 endoscopic, 8 open). Mean age, rates of tracheostomy and vocal fold immobility, and distribution of cleft types were not different between the 2 groups (all P > .2). Mean operative time (P = .004) and duration of hospital stay (P < .001) were significantly shorter in the endoscopic group. All repairs were intact in both groups at final postoperative endoscopy. Rates of persistent laryngeal penetration or aspiration on swallow study were not different between groups (P = 1.000), although results were available for only 11 patients.Endoscopic laryngeal cleft repair using a mass-closure technique provides a durable result while requiring significantly shorter operative times and hospital stays than open repair and avoiding the potential morbidity of laryngofissure. However, open repair may allow the simultaneous performance of other airway reconstructive procedures and may be a useful salvage technique when endoscopic repair fails. Postoperative swallowing results require further study.

  • Standardized Outcome and Reporting Measures in Pediatric Head and Neck Lymphatic Malformations OTOLARYNGOLOGY-HEAD AND NECK SURGERY Balakrishnan, K., Bauman, N., Chun, R. H., Darrow, D. H., Grimmer, J. F., Perkins, J. A., Richter, G. T., Shin, J. J., Shivaram, G. M., Sidell, D. R., Elluru, R. G. 2015; 152 (5): 948-953

    Abstract

    To develop general and site-specific treatment effect and outcome measures to standardize the reporting of head and neck lymphatic malformation (HNLM) treatments.Consensus statement/expert opinion.Multiple tertiary academic institutions.The modified Delphi method is an iterative process of collecting expert opinions, refining opinions through discussion and feedback, statistically aggregating opinions, and using these aggregates to generate consensus opinion in the absence of other data. The modified Delphi method was used by a multi-institutional group of otolaryngology and interventional radiology experts in the field of vascular anomalies to formulate a list of recommended reporting outcomes for the study and treatment of head and neck lymphatic malformations.Through 3 rounds of iteration, 10 expert panelists refined 98 proposed outcome measures and 9 outcome categories to a final consensus set of 50 recommended outcome measures in 3 global categories (general, demographics, and treatment complications) and 5 site-specific categories (orbit, oral cavity, pharynx, larynx, and neck).We propose the first consensus set of standardized reporting measures for clinical and treatment outcomes in studies of HNLMs. Consistent outcome measures across future studies will facilitate comparison of treatment options and allow systematic review. We hope that these guidelines facilitate the design and reporting of subsequent HNLM studies.

  • Role of obesity in otitis media in children. Current allergy and asthma reports Ahmed, S., Arjmand, E., Sidell, D. 2014; 14 (11): 469

    Abstract

    The ongoing childhood obesity epidemic has garnered significant attention among healthcare providers due to its short- and long-term sequelae. Multiple diseases have been associated with obesity, not limited to hypertension, diabetes, and attention deficit hyperactivity disorder. Over the past decade, the relationships between obesity and otologic conditions have been investigated. In this setting, otitis media has remained the focus of research, representing one of the most common pediatric illnesses. Initial studies suggesting a relationship between the two conditions have been supported with epidemiological studies controlling for socioeconomic factors. The purpose of this article is to review our current understanding of the relationship between otitis media and obesity and to discuss the healthcare implications of this association. In addition, several identifiable factors associated with each condition are discussed, as are potential pathophysiologic mechanisms that may help to elucidate the complex and multifactorial relationship between the two disease entities.

  • Epstein-barr DNA serology and positron-emission tomography imaging of the head and neck in pediatric transplant recipients LARYNGOSCOPE Sidell, D., Venick, R. S., Shapiro, N. L. 2014; 124 (5): 1236-1241

    Abstract

    Epstein-Barr virus (EBV) infection is a potential precursor of post-transplantation lymphoproliferative disorder (PTLD) in the pediatric transplant patient. Positron-emission tomography (PET) imaging is increasingly utilized in this population to monitor for neoplasia and PTLD. We assess the association between EBV serum titers and Waldeyer's ring and cervical lymph node PET positivity in the pediatric transplant recipient.Retrospective analysis of EBV serology and PET imaging results in pediatric orthotopic liver transplantation (OLT) recipients.Imaging results and laboratory data were reviewed for all pediatric OLT recipients from January 2005 to July 2011 at a single institution. Charts were evaluated for PET positivity at Waldeyer's ring or cervical lymphatics, and for EBV serology results. Demographic data extracted include patient sex and age at transplantation.A total of 122 pediatric OLT recipients were reviewed. Twelve patients (10%) underwent PET imaging. Overall, four patients (33%) had evidence of PET positivity at Waldeyer's ring or cervical lymphatics. Five patients (42%) had positive EBV serology. There was a significant association between PET imaging results and EBV DNA serology results (P = .01).PTLD surveillance in the pediatric transplant recipient is an important component of long-term care in this population. Although PET imaging is a new modality in monitoring pediatric transplant recipients for early signs of PTLD, an association between EBV serology and PET imaging results appears to exist. With increased implementation, PET imaging will likely prove valuable in its ability to monitor the transplant recipient at risk for PTLD.

  • Risk Factors for Preoperative and Postoperative Hearing Loss in Children Undergoing Pressure Equalization Tube Placement. Otolaryngology--head and neck surgery : official journal of American Academy of Otolaryngology-Head and Neck Surgery Sidell, D., Hunter, L. L., Lin, L., Arjmand, E. 2014; 150 (6): 1048-1055

    Abstract

    Pressure equalization tube (PET) placement is the most common surgical procedure performed during childhood. Current guidelines recommend more prompt management of children with otitis media with effusion who are at greater risk for speech-language and developmental problems. This study was designed to examine risk factors for continued post-PET hearing loss in a large pediatric clinical sample.Retrospective analysis using the electronic medical record.Tertiary care children's hospital.Pediatric patients undergoing PET placement between January 2009 and October 2012 who had audiometric tests.Demographics, patient diagnoses, and hearing loss information were extracted. Multivariate binary logistic regression models were used to identify associations between patient-specific characteristics and the presence of hearing loss.In total, 3949 children with 4598 audiology visits were included (2357 males and 1592 females; mean age, 3.3 years), and 1272 preoperative and 3329 postoperative audiograms were performed. Using multivariate modeling, the only variable significantly associated with preoperative hearing loss was low tympanometric static acoustic admittance. Postoperative hearing loss was positively associated with patient age, preoperative hearing loss, lower tympanometric equivalent canal volumes, and Down syndrome. Other factors, including cranial/facial anomalies, low birth weight or prematurity, allergies, and asthma, were not determined to be risk factors for hearing loss.Our results support hearing testing to identify candidates for PET surgery and to determine treatment effectiveness after surgery, since hearing loss cannot be predicted on the basis of risk or demographic factors. These data have important preoperative counseling and postoperative management implications.

    Abstract

    We review and report the use of high-dose bevacizumab for the treatment of recurrent respiratory papillomatosis (RRP) in pediatric patients.We included all patients with pediatric-onset RRP who underwent bevacizumab (25 mg/mL) injections by a single practitioner. A series of 5 consecutive subepithelial injections were administered at 4- to 6-week intervals with concomitant 532 nm KTP laser ablation. The lesions were staged according to the Derkay staging system. The outcomes included pretreatment and posttreatment Derkay scores, the time interval between procedures, and voice outcomes. The demographic data extracted included sex, age at diagnosis, and current age.Nine patients were included in this study, with 1 patient lost to follow-up; their median age was 8 years (range, 3 to 21 years). The mean bevacizumab dose was 14.25 mg (range, 5 to 45 mg). There was a median Derkay score of 11.5 (range, 4 to 23) at the time of diagnosis and a median 58% improvement following therapy. All patients demonstrated an increased time interval between injections, for a median improvement of 2.05× (range, 1.6× to 3.25×).Evidence exists in support of vascular endothelial growth factor as an important factor in the development of RRP. Although some variability in response is demonstrated by this study, high-dose bevacizumab appears to yield promising results for pediatric patients with RRP.

  • Safety of cidofovir by intratympanic delivery technique ANTIVIRAL THERAPY Ward, J. A., Sidell, D. R., Nassar, M., Reece, A. L., Choo, D. I. 2014; 19 (1): 97-105

    Abstract

    Congenital cytomegalovirus (CMV) infection is one of the most common infectious causes of congenital sensorineural hearing loss. To date, a safe and effective therapy for CMV-induced hearing loss does not exist. We hypothesize that the antiviral cidofovir (CDV) can be delivered to the inner ear via intratympanic (IT) injections to safely and effectively mitigate CMV-induced hearing loss.To evaluate the safety of CDV IT injections, weanling guinea pigs with normal hearing were injected intratympanically with 3 mg or 5 mg concentrations of CDV and compared to control animals injected with sterile saline. A separate group of weanling guinea pigs were inoculated with CMV and a subset of this group was treated with CDV following inoculation.The 3 mg/ml and 5 mg/ml CDV concentrations resulted in hearing loss following IT injection into uninfected animals. No signs of inflammation or toxicity were noted on histologic analysis and there was no evidence of systemic toxicity in serology. Hearing loss induced as a result of guinea pig CMV infection recovered by day 21 in animals treated with IT injections of 5 mg/ml CDV.We provide promising evidence demonstrating both the efficacy and safety of IT CDV in the guinea pig animal model. This research further establishes a sound framework upon which ongoing investigations into drug delivery mechanisms for CMV-induced hearing loss will be based.

    Abstract

    Advances in tissue engineering offer potential alternatives to current mandibular reconstructive techniques; however, before clinical translation of this technology, a relevant animal model must be used to validate possible interventions.To establish the critical-sized segmental mandibular defect that does not heal spontaneously in the rat mandible.Prospective study of mandibular defect healing in 29 Sprague-Dawley rats in an animal laboratory.The rats underwent creation of 1 of 4 segmental mandibular defects measuring 0, 1, 3, and 5 mm. All mandibular wounds were internally fixated with 1-mm microplates and screws and allowed to heal for 12 weeks, after which the animals were killed humanely.Analysis with micro-computed tomography of bony union and formation graded on semiquantitative scales.Seven animals were included in each experimental group. No 5-mm segmental defects successfully developed bony union, whereas all 0- and 1-mm defects had continuous bony growth across the original defect on micro-computed tomography. Three of the 3-mm defects had bony continuity, and 3 had no healing of the bony wound. Bone union scores were significantly lower for the 5-mm defects compared with the 0-, 1-, and 3-mm defects (P < .01).The rat segmental mandible model cannot heal a 5-mm segmental mandibular defect. Successful healing of 0-, 1-, and 3-mm defects confirms adequate stabilization of bony wounds with internal fixation with 1-mm microplates. The rat segmental mandibular critical-sized defect provides a clinically relevant testing ground for translatable mandibular tissue engineering efforts.

  • Obesity and the Risk of Chronic Rhinosinusitis, Allergic Rhinitis, and Acute Otitis Media in School-Age Children LARYNGOSCOPE Sidell, D., Shapiro, N. L., Bhattacharyya, N. 2013; 123 (10): 2360-2363

    Abstract

    To determine if obesity is a significant risk factor for acute otitis media (AOM), allergic rhinitis (AR), or chronic rhinosinusitis (CRS) in children and to understand the potential otolaryngological implications of childhood obesity.Cross-Sectional Analysis.The 2006 and 2008 the Medical Expenditure Panel Survey was utilized to identify school-aged children with AOM, AR, and/or CRS. Risk factors for the diagnoses extracted included standard demographics and the presence or absence of obesity. Multivariate analyses were conducted for associations between childhood obesity and AOM, AR, and CRS.42.1 million (95% CI, 40.4-44.2) school-age children (unweighted N = 10623) were sampled in 2006 and 2008. There was a slight male predominance (51.0% [95% CI, 49.8-52.2]). Of these patients, 2.2 million (95% CI 1.9-2.4) received a diagnosis of AOM, 4.0 million (95% CI 3.6-4.4) received a diagnosis of AR, and 1.7 million (95% CI 1.4-1.9) received a diagnosis of CRS. Approximately 9.3 million (95% CI 8.7-10.0) children were obese, representing 22.2% (95% CI 21.0-23.3) of the U.S. population (age 6-17). Utilizing an adjusted multivariate model, childhood obesity was found to be associated with AOM (odds ratio, 1.44; [95% CI 1.08-1.93]; P = 0.033). Significant associations between obesity and AR (OR 1.14; [95% CI 0.88-1.47]; P = 0.60) or obesity and CRS (OR0.73; [95% CI 0.48-1.10]; P = 0.79) were not identified.Childhood obesity appears to be associated with the development of AOM; however, an association between obesity and AR or CRS was not demonstrated. Given that in the United States nearly one-fourth of all children seeking health care are obese, these data may have important preventative care implications.2C.

  • Bone Morphogenetic Protein-2-Impregnated Biomimetic Scaffolds Successfully Induce Bone Healing in a Marginal Mandibular Defect LARYNGOSCOPE DeConde, A. S., Sidell, D., Lee, M., Bezouglaia, O., Low, K., Elashoff, D., Grogan, T., Tetradis, S., Aghaloo, T., St John, M. 2013; 123 (5): 1149-1155

    Abstract

    To test the osteoregenerative potential and dosing of bone morphogenetic protein-2 (BMP-2)-impregnated biomimetic scaffolds in a rat model of a mandibular defect.Prospective study using an animal model.Varied doses of BMP-2 (0.5, 1, 0.5, 0.5 in microspheres, 5, and 15 μg) were absorbed onto a biomimetic scaffold. Scaffolds were then implanted into marginal mandibular defects in rats. Blank scaffolds and unfilled defects were used as negative controls. Two months postoperatively, bone healing was analyzed with microcomputerized tomography (microCT).MicroCT analysis demonstrated that all doses of BMP-2 induced successful healing of marginal mandibular defects in a rat mandible. Increasing doses of BMP-2 on the scaffolds produced increased tissue healing, with 15 μg demonstrating significantly more healing than all other dosing (P < .01).BMP-2-impregnated biomimetic scaffolds successfully induce bone healing in a marginal mandibular defect in the rat. Percentage healing of defect, percentage of bone within healed tissue, and total bone volume are all a function of BMP-2 dosing. There appears to be an optimal dose of 5 μg beyond which there is no increase in bone volume.NA.

  • Acute tonsillitis. Infectious disorders drug targets Sidell, D., Shapiro, N. L. 2012; 12 (4): 271-276

    Abstract

    Acute tonsillitis is an inflammatory process of the tonsillar tissues and is usually infectious in nature. Acute infections of the palatine tonsils predominantly occur in school-aged children, but patients of any age may be affected. Tonsillitis of viral origin is usually treated with supportive care. Bacterial tonsillitis is most commonly caused by Streptococcus pyogenes. Polymicrobial infections and viral pathogens are also important sources of infection. Penicillins remain the treatment of choice for S. pyogenes tonsillitis, and augmented aminopenicillins have gained utility in concert with the increasing incidence of beta-lactamase producing bacteria. We describe the anatomic features and the immunologic function of the palatine tonsils, including a detailed discussion of history and physical examination findings, treatment recommendations, and possible complications of acute tonsillitis. Establishing an accurate diagnosis and initiating appropriate treatment are key components of managing this common pathologic process.

  • Composite Mandibulectomy: A Novel Animal Model 115th AAO-HNSF Annual Meeting and OTO EXPO Sidell, D. R., Aghaloo, T., Tetradis, S., Lee, M., Bezouglaia, O., DeConde, A., St John, M. A. SAGE PUBLICATIONS LTD. 2012: 932–37

    Abstract

    Segmental mandibular defects can result after the treatment of various pathologic processes, including osteoradionecrosis, tumor resection, or fracture nonunion with sequestration. The variety of etiologies and the frequency of occurrence make the reconstruction of segmental mandibular defects a topic of significant interest. Despite these incentives, a well-established small-animal model of the segmental mandibulectomy, including composite resection, does not exist. The objective of this study is the creation of a reliable animal model that can be used to study the reconstruction of en bloc mandibular defects. Surgical techniques and an array of reconstructive options are described.Description of an animal model.Animal laboratory at a quaternary care university medical center.We present an Animal Research Oversight Committee-approved prospective analysis of survival operations in the rat model. A detailed, stepwise description of surgical technique and relevant intraoperative anatomy is presented. Postoperative management, early pitfalls, surgical complications, and future applications are discussed.A total of 72 operations were performed by a single individual between July and October 2010. Two intraoperative and 9 postoperative complications were recognized. There were 6 orocutaneous fistulas, 2 abscesses, and 1 seroma. There were 4 fatalities, which were attributed to anesthetic complications (2, intraoperative), hematoma formation (1, postoperative), and foreign-body aspiration (1, postoperative).This novel animal model reliably replicates the en bloc segmental mandibular defects seen in our patient population and can be manipulated to achieve a wide variety of research objectives.

  • Demographic Influences on Antibiotic Prescribing for Pediatric Acute Otitis Media OTOLARYNGOLOGY-HEAD AND NECK SURGERY Sidell, D., Shapiro, N. L., Bhattacharyya, N. 2012; 146 (4): 653-658

    Abstract

    To understand the epidemiologic antibiotic treatment patterns and the potential impact of race and insurance status on the medical management of acute otitis media (AOM).Cross-sectional analysis of a national database.National ambulatory care setting.Cases of isolated AOM in children ≤ 16.0 years were extracted from the National Ambulatory Medical Care Survey (2006-2008). The frequency and type of antibiotic prescribed were extracted. A multivariate logistic regression model incorporating age, sex, race, ethnicity, and insurance type was used to determine the influence of these demographic variables on antibiotic prescribing patterns.A total of 15.8 ± 1.5 million cases of AOM were studied (mean age, 3.6 ± 0.3 years; 55.1% ± 2.9% male). Of the children, 15.0% ± 2.8% were Hispanic and 10.4% ± 3.1% were black. Medicaid/State Children's Health Insurance Program and private insurance covered 30.6% ± 4.4% and 69.4% ± 4.4% of children, respectively. Overall, 83.1% ± 2.2% of children received an antibiotic prescription. The most commonly prescribed antibiotics were amoxicillin (6.5 ± 0.9 million), beta-lactamase inhibitors (2.6 ± 0.4 million), and third-generation cephalosporins (2.3 ± 0.4 million prescriptions). On multivariate analysis, insurance status, ethnicity, race, age, and sex did not influence the likelihood of an antibiotic being prescribed during the visit (P = .884, .909, .849, .102, and .931 respectively).Most children receiving medical treatment for AOM receive an antibiotic prescription during their visit. Ethnicity, race, and insurance type do not significantly influence antibiotic prescribing rates for AOM, and nearly all patients have medical insurance.

  • Hypoglossal schwannoma masquerading as a carotid body tumor. Case reports in otolaryngology Lee, M. K., Sidell, D. R., Mendelsohn, A. H., Blackwell, K. E. 2012; 2012: 842761-?

    Abstract

    Study Objective. To describe the clinical presentation, evaluation, and treatment of a hypoglossal schwannoma. Methods. We report an unusual case of a hypoglossal schwannoma presenting as a pulsatile level II neck mass at the bifurcation of the external and internal carotid arteries, mimicking a carotid body tumor. Radiologic findings are reviewed in detail. Results. A 59-year-old female presented to a tertiary care medical center with complaints of a pulsatile right-sided neck mass. An MRA of the neck was obtained demonstrating a 5 cm mass located at the carotid artery bifurcation and causing splaying of the internal and external carotids. Based on clinical presentation and imaging, a diagnosis of a carotid body tumor was conferred and the patient scheduled for excision. Intraoperatively, the mass was noted to arise from the hypoglossal nerve, remaining independent of the carotid artery. On histopathologic analysis, the mass was determined to be consistent with hypoglossal schwannoma. Conclusion. Though rare, the hypoglossal schwannoma should remain a consideration in the evaluation of a parapharyngeal space mass. As this report demonstrates, the clinical and radiologic presentation of a hypoglossal schwannoma may closely mimic that of the more common carotid body tumor.

  • Optimal Timing of Surgical Intervention Following Adult Laryngeal Trauma 114th Annual Meeting of the Triological-Society Mendelsohn, A. H., Sidell, D. R., Berke, G. S., St John, M. WILEY-BLACKWELL. 2011: 2122–27

    Abstract

    Laryngeal trauma is an infrequent diagnosis with a scarcity of published data. We aim to further define the factors associated with positive surgical outcomes of adult laryngeal trauma.Multi-institution database analysis.Of the 1.9 million trauma cases from the National Trauma Database (NTDB), 564 adult trauma events were selected with ICD-9 codes specific to laryngeal trauma.Laryngeal trauma was seen predominately in white (61.5%), middle-aged (40.6 years), male (83.7%) patients experiencing blunt (70.7%) laryngeal injury with multiorgan system (92.2%) trauma. There was an overall 17.9% mortality rate. Within the 564 cases, 133 direct laryngoscopies, 185 tracheostomies, 53 laryngeal suturing, and 60 laryngeal fracture repairs were performed. In univariate negative binomial regression models, trauma severity (P ≤ .01), placement of tracheostomy (P lt; .01), and delayed tracheostomy placement (P = .04, .03, .048) were associated with increased ventilator dependence, intensive care unit (ICU) stay, and overall hospital admission duration. Multivariate regression models demonstrated significant associations between tracheostomy performed within 24 hours and shortened ICU stay (P = .03, β = -.28, SE = 1.7) and overall hospital stay (P = .009, β = -.23, SE = 3.1).The NTDB allows study of the largest laryngeal trauma cohort in modern literature. Although complexities arise in the treatment of laryngeal traumas, when indicated, surgical airway should be placed within 24 hours of presentation to improve the overall hospital course.

    Abstract

    Phosphaturic mesenchymal tumors are rare neoplasms predominantly originating in the trunk and extremities. Malignant variants are exceedingly rare, and can present significant diagnostic challenges to the pathologist and otolaryngologist alike. This report describes the first case of malignant phosphaturic mesenchymal tumor involving the larynx, and emphasizes the importance of vigilance in both histopathologic and clinical actions so that appropriate treatment can be provided in a timely manner. The clinical presentation, radiologic and histologic features, and management are discussed.

  • CO2 Laser Ablation and Balloon Dilation for Acquired Nasopharyngeal Stenosis: A Novel Technique Annual Combined Sections Meeting of the Triological-Society Sidell, D., Chhetri, D. K. WILEY-BLACKWELL. 2011: 1486–89

    Abstract

    Although acquired nasopharyngeal stenosis (NPS) is frequently attributed to infectious and granulomatous processes, it can also occur secondary to external beam radiation therapy for head and neck cancer. NPS can be treated with local flaps, laser excision, nasal stenting, and combinations thereof. Unfortunately, the postoperative course is frequently complicated by scarring and restenosis that often necessitates multiple revision surgeries. The objective of this study is to report a novel endoscopic approach, employing the use of a flexible CO(2) laser in combination with balloon dilation and mitomycin-C application, allowing for the successful treatment of acquired NPS with lasting results.Retrospective review of case series.An endoscope with a working channel is passed transnasally to the location of nasopharyngeal stenosis. A flexible CO(2) laser fiber is then inserted via the working channel of the scope. Precise radial incisions are made on the stenosis using the laser under direct visualization. The laser is removed, and a controlled radial expansion balloon dilation device is inserted, advanced to span the segment of stenosis, and inflated to achieve adequate dilation. Mitomycin-C is then applied topically to the area of dilation.Three patients with severe NPS were treated using this novel technique. All patients had successful long-lasting dilation of NPS without complications over a follow-up period ranging from 12 to 18 months.Acquired NPS can be successfully treated with durable results with radial laser incisions and controlled radial expansion balloon dilation.

  • Diagnostic Accuracy of Ultrasonography for Midline Neck Masses in Children Annual Meeting of the American-Academy-of-Otolaryngology-Head-and-Neck-Surgery-Foundation and OTO EXPO Sidell, D. R., Shapiro, N. L. SAGE PUBLICATIONS LTD. 2011: 431–34

    Abstract

    To evaluate the diagnostic accuracy and to assess the utility of preoperative ultrasonography in the pediatric patient with a midline neck mass.Diagnostic test study.Tertiary care university hospital.An institutional review board (UCLA Office of the Human Research Protection Program)-approved retrospective review of pediatric patients undergoing excision of a midline neck mass between 1999 and 2010 at a tertiary care institution was performed. The preoperative imaging modality, imaging diagnosis, and pathologic results were evaluated.Forty patients were included in this review. This study failed to demonstrate an association between preoperative ultrasound-based diagnoses and postoperative pathologic results (P > .99).Ultrasonography is commonly used in the workup of a midline neck mass in the pediatric population. Despite the utility of preoperative ultrasonography, the diagnostic accuracy of this imaging modality may have significant limitations.

  • Spurious decline in intraoperative parathyroid hormone: false positives in parathyroid surgery AMERICAN JOURNAL OF OTOLARYNGOLOGY Sidell, D., Wang, J., Sercarz, J. 2010; 31 (6): 479-481

    Abstract

    The aims of this study were to (1) describe a false-positive result using a highly sensitive intraoperative parathyroid hormone (PTH) assay in an adult patient with primary hyperparathyroidism and (2) discuss the potential pitfalls of revision parathyroid surgery and the implication of various localization techniques described in the literature.A case report is described from a tertiary care university hospital. A literature review detailing diagnostic tools used to improve outcomes in parathyroid surgery is presented. The potential inaccuracies of intraoperative PTH assays are discussed.We present a 71-year-old woman with primary hyperparathyroidism who was referred to our institution for revision surgery. The patient had preoperative sestamibi imaging that localized a right inferior parathyroid lesion. Intraoperatively, a specimen consistent with parathyroid tissue was removed and sent for frozen section. The intraoperative PTH levels were noted to decrease from 154 pg/mL (preincision) to 28 pg/mL (20 minutes postexcision). The frozen section results were consistent with a lymph node. This stimulated a 4-gland exploration, which confirmed normal left superior and inferior parathyroid glands. A 1.5-cm right retroesophageal parathyroid was subsequently discovered and excised. Final intraoperative PTH levels were 20 pg/mL.Rapid PTH assays have become the mainstay of parathyroid surgery at many institutions; however, despite their accuracy, false-positive results are known to occur. We present a case of an inaccurate decline in intraoperative PTH and use this case report as a means to highlight some potential pitfalls of the test.

  • Improved Tracheoesophageal Prosthesis Sizing in Office-Based Tracheoesophageal Puncture 89th Annual Meeting of the American-Broncho-Esophagological-Association Sidell, D., Shamouelian, D., Erman, A., Gerratt, B. R., Chhetri, D. ANNALS PUBL CO. 2010: 37–41

    Abstract

    Tracheoesophageal puncture (TEP) for postlaryngectomy speech is increasingly being performed as an office-based procedure. We review our experience with office-based TEP and compare outcomes with those of operating room-based TEP. Our hypothesis was that office-based TEP results in improved prosthesis sizing, reducing the number of visits dedicated to prosthesis resizing.A retrospective chart review was performed of all patients who underwent secondary TEP at our institution from 2001 to 2008. The primary dependent measure was the change in the length of the voice prosthesis. We also evaluated the number of visits made to the speech-language pathologist for resizing before a stable prosthesis length was achieved, and the number of days between voice prosthesis placement and the date a stable prosthesis length was observed.Thirty-one patients were included in this study. There was a significant difference in prosthesis length change between patients who had office-based TEP and patients who had operating room-based TEP (p < 0.001). In addition, the office-based cohort required fewer visits to the speech-language pathologist for TEP adjustments before a stable TEP length was achieved (p < 0.001).Voice prosthesis sizing was better in patients who had office-based TEP than in patients who had operating room-based TEP. This outcome is likely due to the lesser degree of swelling of the tracheoesophageal party wall in the office-based procedure.

  • The Use of Ultrasonic Shears for the Harvest of Perforator Free Flaps ARCHIVES OF FACIAL PLASTIC SURGERY Ahmed, S., Sidell, D., Blackwell, K. E., Sercarz, J. A., Abemayor, E., Nabili, V. 2009; 11 (5): 343-346

    Abstract

    A retrospective chart review was performed at a university medical center to evaluate the use of ultrasonic shears for the harvest of perforator free flaps over an 18-month period. The anterolateral thigh (ALT) was the perforator free flap site selected for the study. The site of origin and the number of musculocutaneous perforator vessels that were dissected using ultrasonic shears were recorded, and ALT flap viability and wound-healing complications were evaluated to assess safety. Seventeen patients underwent harvest of ALT perforator free flaps. Successful dissection of musculocutaneous perforators was achieved in 96% (27 of 28) of the descending branch perforators and in 100% (9 of 9) of the transverse branch perforators. Flap viability was 100% (17 of 17). We found that ultrasonic shears were effective and safe to use for harvesting perforator free flaps. According to these preliminary findings, the use of ultrasonic shears appears promising, yet further prospective analysis is needed.

  • Pediatric Squamous Cell Carcinoma: Case Report and Literature Review Annual Meeting of the Western Section of the Triological-Society Sidell, D., Nabili, V., Lai, C., Cheung, G., Kirsch, C., Abemayor, E. JOHN WILEY & SONS INC. 2009: 1538–41

    Abstract

    Describe a rare pediatric malignancy. Discuss the clinical, diagnostic, and therapeutic differences between squamous cell carcinoma (SCC) of the adult and pediatric population.Case report including a detailed radiological and histopathologic analysis and review of the literature.A case report is described from a tertiary care university hospital. Histopathologic assessment and radiological details are reviewed. A literature review of the background, incidence, disease course, and treatment options are presented.This case report presents a 6-year-old male with a 2-month history of an enlarging oral lesion. The patient denied dysphagia, pain, weight loss, bleeding, or loosening of the teeth. Biopsy demonstrated invasive, well-differentiated, exophytic squamous cell carcinoma with perineural and angiolymphatic invasion. Computed tomography and magnetic resonance imaging demonstrated a 2.7 x 3.0 cm poorly marginated infiltrative mass involving the gingival aspect of the superior alveolar ridge and the adjacent bony marrow, primarily to the right of midline. Multiple small subcentimeter lymph nodes were also identified in the bilateral level II to V posterior cervical triangles bilaterally.Pediatric SCC of the oral cavity is indeed a rare entity; however, its presence in the pediatric population should not be ignored. This case report describes the occurrence of SCC in the oral cavity of a 6-year-old male patient, the youngest case ever reported, and is a reminder that a multidisciplinary approach tailored to pediatric individuals is essential to obtain clear diagnoses and appropriate treatment plans.

  • Cystic Lymphatic Malformation of the Middle Ear ANNALS OF OTOLOGY RHINOLOGY AND LARYNGOLOGY Tanna, N., Sidell, D., Schwartz, A. M., Schessel, D. A. 2008; 117 (11): 824-826

    Abstract

    We review the clinical, radiologic, and histopathologic features of cystic lymphangioma of the middle ear, and discuss the developmental etiology and management of such a lesion.We present an unusual location for the development of a cystic lymphangioma with emphasis on etiology, clinical implications, and current treatment.A 10-year-old girl presented with a mass involving the medial surface of the right tympanic membrane. T2-weighted magnetic resonance imaging demonstrated a hyperintense lesion in the anterior-superior middle ear cavity without evidence of vascular abnormalities.To our knowledge, this is the only report of lymphangioma involving the middle ear represented in the English-language literature. Such a lesion has been demonstrated to arise from abnormalities in growth factors that contribute to the tightly regulated process of lymphangiogenesis. Lymphatic malformations can be diagnosed presumptively by virtue of magnetic resonance imaging in combination with a detailed physical examination. The treatment of choice for lymphangiomas located in the middle ear is surgical excision. Definitive diagnosis of the lesion is then made by identifying specific histopathologic characteristics. Although rare and histologically benign, middle ear lymphangiomas may produce significant patient discomfort and ultimately a conductive hearing loss. Therefore, these lesions warrant early recognition and treatment.

  • Adult intralesional cidofovir therapy for laryngeal papilloma Combined Otolaryngological Spring Meeting Tanna, N., Sidell, D., Joshi, A. S., Bielamowicz, S. A. AMER MEDICAL ASSOC. 2008: 497–500

    Abstract

    To assess the long-term efficacy of intralesional cidofovir therapy in a previously reported cohort of adult subjects with laryngeal papilloma.Retrospective review.Tertiary care medical center.We previously reported on the favorable clinical response to intralesional cidofovir therapy in 13 adult subjects. The subjects were enrolled in an open-trial prospective study (1997-2001) and completed the injection-only treatment protocol, and all subjects achieved a disease remission after a mean of 6 injections. In the present study, we review the clinical course of these subjects during an extended observational period (2001-2006).Patients with documented relapse of disease underwent additional intralesional cidofovir injections.Additional interventions, disease severity, and adverse outcomes are reported.Following the original cidofovir protocol, 6 patients (46%) received no further interventions. The remaining 7 patients (54%) required further treatment for disease relapse, with a mean duration of remission before relapse of 1.05 years. Of the 7 patients who experienced disease relapse, 2 continued to have stable disease with regular injections, 2 were lost to follow-up during relapse treatment, and 3 achieved disease remission again. For this latter cohort, the mean number of injections per year necessary to achieve a second remission was 3.82. This compares with a mean of 1.77 injections per year that these patients received on an as-needed basis prior to the original study.Intralesional cidofovir injections have been shown to be an effective therapy for adult laryngeal papilloma and should be considered in those patients who experience disease relapse.
