Suppression of epithelial signal transducer and activator of transcription 1 activation by extracts of Aspergillus fumigatus.

Aspergillus fumigatus (AF) is often pathogenic in immune-deficient individuals and can cause life-threatening infections such as invasive aspergillosis. The pulmonary epithelial response to AF infection and the signaling pathways associated with it have not been completely studied. BEAS-2B cells or primary human bronchial epithelial cells were exposed to extracts of AF and challenged with IFN-ß or the Toll-like receptor 3 agonist double-stranded RNA (dsRNA). Cytokine release (B-cell activating factor of the TNF family [BAFF], IFN-γ-induced protein-10 [IP-10], etc.) was assessed. AF extract was separated into low-molecular-weight (LMW) and high-molecular-weight (HMW) fractions using ultra 4 centrifugal force filters to characterize the activity. Real-time PCR was performed with a TaqMan method, and protein estimation was performed using ELISA techniques. Western blot was performed to assess phosphorylation of signal transducer and activator of transcription 1 (STAT1). IFN-ß and dsRNA induced messenger RNA (mRNA) expression of BAFF (350- and 452-fold, respectively [n = 3]) and IP-10 (1,081- and 3,044-fold, respectively [n = 3]) in BEAS-2B cells. When cells were pretreated with AF extract for 1 hour and then stimulated with IFN-ß or dsRNA for 6 hours, induction of BAFF and IP-10 mRNA was strongly suppressed relative to levels produced by IFN-ß and dsRNA alone. When compared with control, soluble BAFF and IP-10 protein levels were maximally suppressed in dsRNA-stimulated wells treated with 1:320 wt/vol AF extract (P < 0.005). Upon molecular size fractionation, a LMW fraction of AF extract had no measurable suppressive effect on IP-10 mRNA expression. However, a HMW fraction of the AF extract significantly suppressed IP-10 expression in BEAS-2B cells that were stimulated with dsRNA or IFN-ß. When BEAS-2B cells were pretreated with AF extract and then stimulated with IFN-ß, reduced levels of pSTAT1 were observed, with maximum suppression at 4 and 6 hours. Our results show that AF extracts suppressed expression of inflammatory cytokines in association with inhibition of the IFN-ß signaling pathway and suppression of the formation of pSTAT1.

Clinical indicators that predict the presence of moderate to severe obstructive sleep apnea after adenotonsillectomy in children.

OBJECTIVE: To determine if clinical indicators can predict the presence of moderate to severe Obstructive Sleep Apnea (OSA) after Adenotonsillectomy (T&A) in children. STUDY DESIGN: Retrospective study. SETTING: Urban Tertiary Care Pediatric Hospital. METHODS: Parents of children (<18 yrs.) with OSA completed a 55-item questionnaire based on their child's symptoms at the time of preoperative polysomnography and then again at the follow up polysomnography completed 3 to 6 months after T&A. MAIN OUTCOME MEASURES: 55 item questionnaire, polysomnography variables. RESULTS: 97 children were included (59 Male and 38 Female). The mean preoperative apnea hypopnea index (AHI) was 30.5±31.6/h and the mean postoperative AHI was 4.4±6.0/h. After T&A, all 97 children had reduction in AHI, and 35 (36.1%) no longer had OSA (AHI<1/h). The total symptom scores decreased from 15.8±9.4 to 11.3±8.7 after T&A (p<.0001). Fourteen symptoms highly predictive of moderate to severe OSA were identified in the univariate analysis (p<0.1). Using a cut-point of 4, this 14-item subscale illustrated an overall predictability of 72.2% (73.7% sensitivity and 70.0% specificity) for identifying children with moderate to severe OSA. CONCLUSION: A cluster of 14 clinical sleep symptoms are highly predictive of moderate to severe OSA and can serve as clinical predictor for the presence of moderate to severe OSA after T&A.

International pediatric otolaryngology group (IPOG) consensus on approach to aspiration.

OBJECTIVE: To provide recommendations for a comprehensive management approach for infants and children presenting with symptoms or signs of aspiration. METHODS: Three rounds of surveys were sent to authors from 23 institutions worldwide. The threshold for the critical level of agreement among respondents was set at 80 %. To develop the definition of "intractable aspiration," each author was first asked to define the condition. Second, each author was asked to complete a 5-point Likert scale to specify the level of agreement with the definition derived in the first step. RESULTS: Recommendations by the authors regarding the clinical presentation, diagnostic considerations, and medical and surgical management options for aspiration in children. CONCLUSION: Approach to pediatric aspiration is best achieved by implementing a multidisciplinary approach with a comprehensive investigation strategy and different treatment options.

Fiberoptic Endoscopic Evaluation of Swallowing in the Breastfeeding Infant.

OBJECTIVE: To demonstrate the importance of utilizing fiberoptic endoscopic evaluation of swallowing (FEES) when evaluating breastfeeding infants with suspected dysphagia. Failure to recognize and account for the fundamentally different physiology of the primarily breastfed infant can lead to false assumptions about the safety of breastfeeding in this understudied patient population. METHODS: Case-series. The medical records of patients referred to an urban, university-based, pediatric hospital for FEES from February 2017 to October 2020 were reviewed. Their presenting symptoms, dysphagia severity, comorbidity, dysphagia workup, and management were analyzed. The standardized Dysphagia Outcome and Severity Scale was used to appraise dysphagia severity. RESULTS: 204 FEES exams were reviewed. 35 were conducted on breastfed infants. 34 of the 35 infants calmed for the FEES exam while breastfeeding. Cohorts were defined by a particular presenting sign (cough, laryngeal congestion, choking, and respiratory illness) and anatomical characteristic (laryngomalacia, vocal cord paralysis, aspiration, penetration, etc.) and then compared to all other exams. The average dysphagia score for all the exams was 2.37. Patients presenting with laryngeal congestion had an average dysphagia score of 2.81. There was no difference in dysphagia score based on comorbidities or anatomy. CONCLUSIONS: FEES is the instrumental exam of choice when evaluating a primarily breastfed infant who has suspected dysphagia. The exam is well tolerated and provides accurate, objective information while accounting for this population's unique swallowing physiology. Primarily breastfed infants presenting with laryngeal congestion are more likely to have clinically worse dysphagia than those presenting with other clinical symptoms.

Associations of deep sleep and obstructive sleep apnea with family relationships, life satisfaction, and physical stress experience in children: a caregiver perspective.

STUDY OBJECTIVES: Obstructive sleep apnea (OSA) and poor quality of sleep negatively impacts health-related quality of life in adults, but few studies have evaluated the association between sleep disturbance (eg, OSA, inadequate sleep) and health-related quality of life domains (eg, family relations, life satisfaction) in children. METHODS: Children ages 8-17 years referred to a sleep center for routine polysomnography from April 2022 to August 2022 were approached to participate in the study, and children visiting the department of pediatrics for their wellness visit were recruited for comparisons. Statistical analysis was conducted using R 3.6.0. RESULTS: Ninety-nine children were recruited from the sleep clinic, and 23 children were recruited from the primary care clinic. Of these children, 62 were diagnosed with obstructive sleep apnea (31 mild, 12 moderate, 19 severe), and 37 did not meet criteria for a diagnosis. Health-related quality of life domains did not differ across OSA severity levels. Children in general had lower life satisfaction and higher physical stress experience compared to children visiting for their wellness examination (well-child visitors, P = .05 and P = .005, respectively). Children with severe OSA had significantly lower life satisfaction and significantly higher physical stress experience when compared with well-child visitors (P = .008 and P = .009, respectively). Correlation analysis showed that N3 (deep) sleep was positively associated with family relations and life satisfaction, while it was negatively associated with anger. CONCLUSIONS: Based on caregiver response, N3 sleep is positively associated with family relations and life satisfaction and negatively associated with anger. Severe OSA is associated with lower life satisfaction and higher physical stress experience. CITATION: Bhushan B, Zee PC, Grandner MA, et al.

Evaluating dysphagia in infants with congenital heart disease using Fiberoptic Endoscopic Evaluation of Swallowing.

OBJECTIVE: Dysphagia is common in infants with congenital heart disease (CHD). However, there is minimal published data regarding its management outside of the perioperative period. The objective of this study is to describe the role of Fiberoptic Endoscopic Evaluation of Swallowing (FEES) in the diagnosis and management of dysphagia in infants with CHD. METHODS: Infants with CHD who underwent FEES exam for evaluation of swallowing dysfunction between February 2015 and February 2021 at a university-based, tertiary care urban pediatric hospital were studied. Demographic data, presenting symptoms, medical history, and dysphagia history were examined. The validated Dysphagia Outcome and Severity Scale (DOSS) was used to standardize and compare dysphagia severity. RESULTS: 62 FEES exams were performed on 48 patients. All 48 patients were diagnosed with dysphagia and had a mean dysphagia severity score (DOSS) of 2.68. Patients with wet laryngeal congestion on presentation had worse mean DOSS score and were more likely to demonstrate aspiration on FEES exam (p < 0.01). There was no significant difference in mean DOSS or presence of aspiration when comparing infants who had cardiothoracic surgery, vocal cord paralysis, or lower respiratory tract illness with those who had not (p > 0.05). CONCLUSION: A FEES exam is an effective and well-tolerated procedure for evaluating swallowing dysfunction in pediatric patients with CHD and its use reduces radiation exposure for this vulnerable population. Wet laryngeal congestion was found to be predictive of more severe dysphagia and aspiration. There is no significant association between severity of dysphagia or aspiration on FEES exam and history of cardiac surgery, vocal cord paralysis, or lower respiratory tract illness.

Diagnosis and management of type I posterior laryngeal clefts.

OBJECTIVES: We review the diagnosis and management of type I posterior laryngeal clefts (PLCs). METHODS: We performed a retrospective study at a tertiary-care children's hospital of children who were diagnosed with a PLC between January 2003 and August 2008. We studied concurrent airway anomalies, comorbidities, presenting symptoms, age at the time of aspiration resolution, and rate of aspiration resolution. RESULTS: Sixty-seven children with PLCs were identified (41 boys and 26 girls). Fifty-nine had type I clefts, 6 had type II, and 2 had type III. Of the 59 type I cases, 15 (25.4%) were surgically repaired by endoscopy. Eleven of these 15 children (73.3%) have had symptomatic improvement since the surgery, and 7 of those 11 (63.6%) are tolerating thin liquids by mouth. Two of the 15 (13.3%) displayed no improvement with surgery, and 2 of the 15 (13.3%) were lost to follow-up. Forty-four of the 59 type I clefts (74.6%) were managed nonsurgically. Twenty of these 44 children (45.5%) did not present with aspiration. Twenty-four of the 44 (54.5%) presented with aspiration, and 16 of the 24 (66.7%) are now tolerating thin liquids by mouth. Seven of these 24 patients (29.2%) are still aspirating, and 1 has died. The average time to resolution of aspiration was 7.8 months for the surgical group and 13.6 months for the nonsurgical group (p = 0.19). In the surgical group, the average age at resolution of aspiration for patients who received their diagnosis at 0 to 6 months of age was 21.5 months; that for those with a diagnosis at 6 to 12 months was 27.3 months; and that for those with a diagnosis at older than 12 months was 27.3 months (p = 0.31). In the nonsurgical group, the average age at resolution of aspiration for patients who received their diagnosis at 0 to 12 months of age was 15.8 months; that for those with a diagnosis at 12 to 24 months was 27.3 months; and that for those with a diagnosis at older than 24 months was 77.3 months (p = 0.0015). CONCLUSIONS: We found that (1) the reported incidence of type I PLCs is increasing; (2) type I PLCs can often present without clinical aspiration; (3) aspiration caused by type I PLCs can be managed medically or surgically; and (4) operative intervention is advantageous for patients who have severe symptoms or who have persistent aspiration after 2 years of age.

Fiberoptic Endoscopic Evaluation of Swallowing Across the Age Spectrum.

Purpose Fiberoptic endoscopic evaluation of swallowing (FEES) is a widely used instrumental procedure used to assess swallowing function in persons of all ages, from infants to older adults. In this article, the history of FEES in adults, the protocol, the scoring system, and the interpretation of abnormal findings are summarized. The use of FEES to guide treatment in adults is also covered briefly. Following this review in adults, the use of FEES in infants and children is presented, including the anatomical-physiological assessment and the assessment of swallowing of food and liquid. Interpretation of findings and therapeutic applications are discussed. Conclusion FEES is a valuable part of the clinical protocol for evaluation and management of dysphagia across the life span. It provides a mechanism for in-depth analysis of swallowing structures and function during intake of liquid and food boluses. Future developments include standardized training content to ensure clinical competency and the development of standardized examination and interpretation protocols.

Polysomnography Outcomes after Supraglottoplasty in Children with Obstructive Sleep Apnea.

OBJECTIVE: Laryngomalacia has been reported to contribute to the severity of obstructive sleep apnea (OSA) in children. It is unclear if surgical treatment of laryngomalacia improves polysomnography (PSG) outcomes in these patients. The objective of this study is to report the impact of supraglottoplasty on PSG parameters in children with laryngomalacia-related OSA. STUDY DESIGN: Retrospective case series. SETTING: Tertiary care medical center. SUBJECTS AND METHODS: Historical cohort study of consecutive children with laryngomalacia who underwent supraglottoplasty and who had undergone overnight PSG before and after surgery. RESULTS: Forty-one patients were included in the final analysis: 22 (53.6%) were male, and 19 (46.3%) were female. The mean ± SEM age of patients at preoperative PSG was 1.3 ± 0.89 years (range, 0.003-2.9). In entire cohort, the mean obstructive apnea-hypopnea index score was reduced from 26.6 events/h before supraglottoplasty to 7.3 events/h after surgery (P = .003). Respiratory disturbance index was reduced from 27.3 events/h before supraglottoplasty to 7.8 events/h after surgery (P = .003). The percentage of REM sleep decreased from 30.1% ± 2.4 to 24.8% ± 1.3 (P = .04). Sleep efficiency was improved (P = .05). CONCLUSION: Overall, supraglottoplasty significantly improved several PSG outcomes in children with laryngomalacia. However, mild to moderate OSA was still present postoperatively in most children. This suggested a multifactorial cause for OSA in this population.

Congenital laryngeal stenosis.

Congenital subglottic stenosis is rare and as a consequence may not be considered in children experiencing respiratory difficulty at birth. Diagnosis after a child already is intubated complicates the recognition and blurs the boundary between congenital and acquired lesions. This article discusses the anatomy of the larynx, its common anatomic variations, and its response to trauma, a thorough understanding of which is required for the accurate diagnosis and treatment of this complicated problem. The authors discuss evaluation and assessment options to guide treatment.

Aspiration following CO(2) laser-assisted supraglottoplasty.

OBJECTIVE: To review the incidence, risk factors, and treatment of aspiration following CO(2) laser-assisted supraglottoplasty for severe laryngomalacia (LM). DESIGN: IRB approved retrospective study of pediatric patients with severe LM treated with CO(2) laser supraglottoplasty over a 5-year period. SETTING: Tertiary pediatric hospital. PATIENTS: Fifty-two patients met inclusion criteria. Indication for supraglottoplasty was respiratory distress in 90% of patients and/or failure to thrive in 19%. INTERVENTIONS: All children underwent bilateral CO(2) laser supraglottoplasty and were assessed postoperatively with swallow evaluation by a speech pathologist. Videoflouroscopic evaluation was utilized to confirm aspiration and guide management. MAIN OUTCOME MEASURES: Aspiration, treatment required to manage aspiration, duration of treatment required. RESULTS: Thirty-seven percent (20/52) of patients had postoperative aspiration. Aspiration was demonstrated on videoflouroscopic swallow study (VFSS) after supraglottoplasty is 28% (12/43). All patients with newly diagnosed aspiration had treatment with thickened and/or nasogastric feedings with mean resolution time of 6 months. In nine children with preoperative aspiration, eight (89%) had postoperative aspiration and seven required gastrostomy tube placement for feeding management. All individuals requiring gastrostomy for aspiration management had neurological conditions. In the absence of preoperative clinically evident aspiration, children with neurological conditions have an equivalent rate of postoperative aspiration as healthy children. The only risk factor for postoperative aspiration was preoperative aspiration. CONCLUSION: Aspiration is more common after CO(2) laser-assisted supraglottoplasty than previously recognized. In otherwise healthy children, postoperative aspiration is of short duration and can be treated with conservative measures. Optimal treatment after supraglottoplasty includes screening for and management of aspiration in conjunction with a speech pathologist.

A Chronic Glottic Foreign Body Diagnosed by Radiograph after 9 Months of Symptoms.

A six-year-old girl presented to an emergency room after describing choking on a rubber band. She was in no distress and was discharged. Over the course of the next 9 months, she had numerous outpatient and emergency room visits due to intermittent stridor, difficulty breathing, and hoarseness. Eventually, dedicated airway films revealed a laryngeal foreign body. During rigid bronchoscopy, a two-centimeter rubber band was discovered in the larynx. It extended from the supraglottis, through the glottis, and into the subglottis. It was successfully removed. The patient was asymptomatic 24 hours later. This case highlights the appropriate evaluation and management of a child with stridor.

Branchial anomalies in the pediatric population.

OBJECTIVE: We sought to review the presentation, evaluation, and treatment of branchial anomalies in the pediatric population and to relate these findings to recurrences and complications. STUDY DESIGN AND SETTING: We conducted a retrospective study at a tertiary care pediatric hospital. PATIENTS: Ninety-seven pediatric patients who were treated for branchial anomalies over a 10-year period were reviewed. Patients were studied if they underwent surgical treatment for the branchial anomaly and had 1 year of postoperative follow-up; 67 children met criteria, and 74 anomalies were studied. RESULTS: Patients with cysts presented at a later age than did those with branchial anomaly fistulas or sinus branchial anomalies. 32% of branchial anomalies were previously infected. Of these, 71% had more than one preoperative infection. 18% of the BA were first arch derivatives, 69% were second arch derivatives and 7% were third arch derivatives. There were 22 branchial cysts, 31 branchial sinuses and 16 branchial fistulas. The preoperative and postoperative diagnoses differed in 17 cases. None of the excised specimens that contained a cystic lining recurred; all five recurrences had multiple preoperative infections. CONCLUSIONS: Recurrence rates are increased when there are multiple preoperative infections and when there is no epithelial lining identified in the specimen.

Effect of vascular endothelial growth factor on laryngeal wound healing in rabbits.

OBJECTIVE: Study the effects of vascular endothelial growth factor (VEGF) on laryngeal wound healing in a rabbit model. STUDY DESIGN: Prospective, randomized, blinded. METHODS: The anterior cricoid cartilage of 10 rabbits was split and a VEGF-soaked collagen sponge was sewn between the cut edges. In 10 control animals, the collagen sponge was soaked with phosphate-buffered saline solution. The larynx was harvested on day 10. The degree of epithelial closure, the degree of soft tissue closure, and the presence of inflammatory cells was graded. RESULTS: There was complete epithelial closure in the control group. There was a slightly higher, but not statistically significant, grade of soft tissue closure in the experimental group. The experimental group had a lower but not statistically significant acute inflammatory response score. CONCLUSIONS: The topical application of VEGF through an implanted collagen sponge to an anterior, subglottic incision in a rabbit has no significant effect on tracheal luminal epithelial closure, acute inflammatory response, or soft tissue repair at postsurgical day 10.

The "Surgeon on Service" Model for Timely, Economically Viable Inpatient Care of Tracheostomy Patients in Academic Pediatric Otolaryngology.

Importance: The traditional practice model for pediatric otolaryngologists at high-volume academic centers is to simultaneously balance outpatient care responsibilities with those of the inpatient service, emergency department, and ambulatory care clinics. This model leads to challenges with care coordination, timeliness of nonemergency operative care, and consistent participation in care and consultation at the attending surgeon level. The "surgeon on service" (SOS) model-where faculty members rotate to manage the inpatient service in lieu of outpatient responsibilities-has been described as one method to address this conundrum. The operational and economic feasibility of the SOS model has been demonstrated; however, its impact on care coordination, time from consultation to surgical care, and length of stay (LOS) have not been evaluated. Objective: To determine the impact of the SOS model on the quality principles of timeliness and efficiency of tracheostomy tube placement and to determine if the SOS model is fiscally feasible in an academic pediatric otolaryngology practice. Design, Setting, and Participants: Medical record review of patients undergoing tracheostomy in a pediatric academic medical center and survey of their treating physician trainees, comparing the 6-month SOS pilot phase (postimplementation, January-June 2016) with the 6-month preimplementation period (January-June 2015). Intervention: Implementation of the SOS model. Main Outcomes and Measures: Time to tracheostomy, frequency of successful coordination of tracheostomy with gastrostomy tube placement, total LOS, productivity measured in work relative value units, and responses to trainee surveys. Results: Of the 41 patients included in the study (24 boys and 17 girls; mean age, 3 years; range, 3 months to 17 years), 15 were treated before SOS implementation, and 26 after. Also included were 21 trainees. Before SOS implementation, median time to tracheostomy was 7 days (range, 2-20 days); after SOS implementation, it was 4 days (range, 1-10 days) (difference between the medians, before to after, -3 days; 95% CI, -5 to 0 days). There was no significant difference in overall LOS or ability to coordinate tracheostomy with gastrostomy tube placement. Preimplementation trainee surveys cited dissatisfaction with the communication channels to the primary team when the consulting surgeon was not immediately available to perform tracheostomy. No challenges were reported after implementation. Productivity was comparable to that in the outpatient setting. Conclusions and Relevance: In this study, the presence of a rotating inpatient pediatric otolaryngologist was a productive approach to patient care associated with more timely performance of tracheostomy. Other benefits were an improved balance of service with education to trainees and a better perception of communication with consulting services.

Clinical symptoms that predict the presence of Obstructive Sleep Apnea.

OBJECTIVE: To determine if a set of clinical symptoms can help in determining the presence and severity of OSA. SETTING: Tertiary urban pediatric hospital. METHODS: Parents of children undergoing an overnight PSG answered a 56 item questionnaire based on their child's symptoms. The responses to the questionnaire were compared between patients with different severities of OSA (s determined by PSG) and those without OSA. Responses to questionnaire were also analyzed between obese and non-obese patients. RESULTS: 235 children were included (140 male and 95 female) with a mean age of 5.76 ± 2.78 years. The mean Apnea Hypopnea Index (AHI) was 7.78 ± 14.50 events/hour (range 0-110 events/h). 74 (31.5%) children had mild-OSA (AHI between 1 and 4.99 events/h), 31 (13.19%) had moderate-OSA (AHI between 5 and 9.99 events/h), 58 (24.7%) had severe-OSA (AHI≥10events/h) and the remaining 72 (30.64%) had No-OSA (AHI≤1event/h). 87 (37%) patients were obese. Eight clinical symptoms in non-obese and six clinical symptoms in obese patients predicted the mild to severe OSA. Sixteen symptoms in non-obese patients and nine symptoms in obese patients predicted the presence of severe OSA in these patients. CONCLUSION: Clinical symptoms reported in this study are useful to predict the presence of and the severity of OSA in children. Clinical symptoms can also predict the presence and severity of OSA in children who are obese, however, the symptoms required to make the prediction are different in obese children.

Development of the maxillary sinus in infants and children.

OBJECTIVE: To examine the age related volume change of the maxillary sinus in children by measuring the change of the height, weight, and depth using computed tomography (CT). METHODS: Children <18 years of age who underwent a CT Scan of the sinuses for reasons other than sinus related issues were included in the study. RESULTS: 139 patients were included (68 females and 71 Males) and the mean age of the patients was 9.6 ± 5.4 years. The cohort was divided into three groups based on their ages - Age <6 years (n = 45), age between 6 and 12 years (n = 44) and age > 12 years (n = 50). Patients in each age group demonstrated an increase in their Maxillary sinus height (p<0.001). Patients < 6years of age and between 6 and 12 years of age had a significant increase in their maxillary sinus width and depth (p < 0.001). The maxillary sinus width, depth and volume did not increase significantly after the age of 12 years in these patients. CONCLUSION: We demonstrated periods of significant size increase of the maxillary sinuses as determined by different dimensions in children at various ages. The height of the maxillary sinus has steady growth from birth to at least the age of 18 years. The width and depth increase up to 12 years of age.

The impact of delayed surgical drainage of deep neck abscesses in adult and pediatric populations.

OBJECTIVES/HYPOTHESIS: The conventional treatment for deep neck abscesses in adults is antibiotic therapy with surgical drainage, whereas in children there is debate about the role of surgical drainage versus conservative therapy. It is presently unclear if delayed surgical drainage negatively affects outcomes. STUDY DESIGN: We performed a multicenter, prospective, risk-adjusted cohort study of adult and pediatric patients with deep neck abscess who received incision and drainage within 7 days of admission in the American College of Surgeons National Surgical Quality Improvement Program from 2005 to 2013 (adults) and from 2012 to 2013 (pediatrics). METHODS: Patients were compared based on age (≤ 18 years, > 18 years), timing of surgical drainage (day 0, day 1-2, or day 3-7), and complication rates (specifically, abscess-specific morbidity and mortality [M&M]). Multivariate regression was performed to control for preoperative differences. RESULTS: A total of 1,012 cases of deep neck abscess were identified (347 adult, 665 pediatric). In adults, delay in surgical drainage was associated with increased abscess-specific M&M, from 11.5% (day 0) to 17.3% (day 1-2) to 25.0% (day 3-7) (P = 0.02). On multivariate regression, delay in drainage of ≥ 3 days in adults was associated with a 2.38-fold increase in M&M (95% confidence interval 1.01-5.59, P = 0.019). In pediatrics, there was no association between surgical delay and increased abscess-specific M&M, with rates of 5.0% (day 0), 4.0% (day 1-2), and 4.8% (day 3-7) (P = 0.68). CONCLUSION: In adults, delay in surgical drainage of deep neck abscess is associated with increased M&M. There is no association between timing of drainage and M&M in children. LEVEL OF EVIDENCE: 2c.

Fiberoptic examination of swallowing in the breastfeeding infant.

OBJECTIVES/HYPOTHESIS: Fiberoptic endoscopic evaluation of swallowing (FEES) is the only instrumental exam that can be used to assess swallowing in a breastfeeding infant. There is minimal data on its efficacy and safety in this patient population. Analyze the common indications for, findings of, and safety of FEES exam in breastfeeding infants. STUDY DESIGN: Case series. METHODS: Consecutive 10 months old or younger breastfed infants undergoing a FEES exam between June 1, 2012, and August 1, 2014, at a university-based, tertiary care urban children's hospital were studied. Common indications for and findings of FEES, as well as complications of the procedure, were determined. RESULTS: Twenty-four FEES were reviewed on 23 patients. There were 14 males (58%). The average age was 14 weeks, and two children were premature. Common indications for FEES were feeding difficulties (52%), noisy breathing with/without feeding (28%), and cyanosis (16%). Of the patients who participated in active breastfeeding during the exam, a functional swallow was identified in 12.5%. The remaining patients demonstrated dysphagia characterized by laryngeal penetration (83%) and/or direct aspiration (50%). The most common findings were laryngeal edema (29%), anterior displacement of glottis structures (14%), and cobblestoning (11%). There was no morbidity directly associated with the procedure. No cyanosis or respiratory distress occurred during or immediately after the procedure. CONCLUSION: Performing FEES exams on breastfeeding infants is safe and effective. There is no other instrumental evaluation of swallowing to assess dysphagia in this population. LEVEL OF EVIDENCE: 4. Laryngoscope, 126:1681-1686, 2016.

Antibiotic Prescribing by Physicians Versus Nurse Practitioners for Pediatric Upper Respiratory Infections.

BACKGROUND: This study investigates differences in antibiotic prescribing rates for pediatric upper respiratory infections (URIs) between physicians and nurse practitioners (NPs). METHODS: Visits by children <18 years old diagnosed with URI to physicians or NPs between 2001 and 2010 were abstracted from the National Ambulatory Medical Care Survey and National Hospital Ambulatory Care Survey. Logistic regression analyses examined variations in antibiotic prescribing rates. RESULTS: Upper respiratory infections accounted for approximately 439 ± 21.5 million visits. Patients seen by NPs were more likely to have Medicaid, live in the lowest median household income quartile zip codes and micropolitan locations, and live in the South compared to patients seen by physicians. Nurse practitioners prescribed antibiotics 66.7% ± 4.2% of the time versus physicians at 52.8% ± 0.8% for URI visits (unadjusted P-value = .002). Adjusted by specialty, URI type, and chronic diseases, NPs had marginally significantly different odds of prescribing antibiotics (OR = 1.6, 95% CI, 1.0-2.6, P-value = .048), but the association with prescribing broad-spectrum antibiotics is not as strong (adjusted P-value = .063). Patient visits to a pediatric (OR = 0.54, 95% CI, 0.43-0.67) or ENT/surgery practice (OR = 0.11, 95% CI, 0.06-0.18) had lower odds of antibiotic prescribing compared to general/family medicine practices. Year (2001-2010) was not significantly associated with antibiotic or broad-spectrum antibiotic prescribing rates for physicians, but rates for NPs fell for otitis media (P-value = .007) from 90.2% ± 8.2% (2001-2002) to 74.8% ± 6.8% (2009-2010) of visits. CONCLUSIONS: Nurse practitioners have higher rates of antibiotic prescribing compared to physicians for pediatric patients with URIs; however, this difference is less after adjusting for specialty. Examining comparative antibiotic prescribing is important to promote evidence-based practice and adoption of clinical guidelines.
