Positive bronchoalveolar lavage pepsin assay associated with viral and fungal respiratory infections in children with chronic cough.

OBJECTIVE: To assess the association between commonly obtained endoscopic and serologic data and bronchoalveolar lavage pepsin assay (BAL) results in children with chronic cough. STUDY DESIGN: We performed a retrospective chart review of 72 children with a BAL pepsin obtained through our Aerodigestive Center over an 18-month period. BAL outcomes include evidence of viral, bacterial, or fungal infection, presence of lipid-laden macrophages, and cytology (eosinophils, neutrophils, and lymphocytes). Gastrointestinal outcomes include esophagogastroduodenoscopy (EGD) and pH impedance probe findings. Other characteristics include serum eosinophils, neutrophils, and lymphocytes; spirometry; FeNO; and IgE. RESULTS: Seventy-two patients underwent BAL pepsin testing. Median age was 4.9 years, 30.6% had severe persistent asthma, and 59.2% were on reflux medication. There was an association between positive BAL pepsin assay and positive viral panel (p = .002) or fungal culture (p = .027). No significant association found between positive BAL bacterial culture; BAL cytology; the presence of BAL lipid-laden macrophages; IgE; spirometry; FeNO; CBC neutrophil, eosinophil, or lymphocytes; pH impedance testing parameters; or EGD pathology. CONCLUSIONS: BAL pepsin is associated with a positive BAL viral PCR or fungal culture. Lack of correlation between pepsin-positivity and pH-impedance parameters or EGD pathology suggests microaspiration may be due to an acute event (such as a respiratory infection) rather than chronic gastroesophageal reflux disease. This may be especially true in the presence of a positive viral panel or fungal culture when a BAL pepsin is obtained.

Pediatric Quality-of-Life Scores Following a Multidisciplinary Aerodigestive Team Approach to Manage Chronic Cough.

OBJECTIVES: Chronic recalcitrant cough is present in 2/3 of pediatric patients evaluated in our tertiary-care multidisciplinary aerodigestive clinic (ADC). This study aimed to determine the impact of chronic cough and efficacy of ADC treatment using the validated Pediatric-Cough Quality-of-Life-27 tool (PC-QOL-27). METHODS: The PC-QOL-27 survey was administered to ADC patients with chronic cough at initial clinic visit and 6 to 12 weeks after cough management. Pre and post survey scores, demographic data, treatment and evaluation season were collected over 16 months. RESULTS: Twenty parents completed pre and post PC-QOL-27 surveys (mean 12.1 weeks later). Patient median age was 6.04 years (IQR: 2.2-10.44 years). A total of 65% were males and 65% were African American. Management was tailored based on clinical assessment and diagnostic studies, including direct laryngoscopy/bronchoscopy (4), pulmonary function tests (PFT's 9), esophagogastroduodenoscopy (9), and flexible bronchoscopy/lavage (9).Following ADC management, changes in physical, social and psychological domain scores of the PC-QOL-27 each met the threshold for minimal clinical important difference (MCID) indicating a clinically meaningful improvement. Improvements were most notable in the physical domain where post survey scores significantly improved from pre-survey scores (P = .009) regardless of age, gender, ethnicity, history of endoscopy and season. CONCLUSIONS: The physical impact of chronic cough in pediatric patients who failed prior management by a single specialist was lessened by an ADC team approach to management.

Otitis Media Middle Ear Effusion Identification and Characterization Using an Optical Coherence Tomography Otoscope.

OBJECTIVE: To determine the feasibility of detecting and differentiating middle ear effusions (MEEs) using an optical coherence tomography (OCT) otoscope. STUDY DESIGN: Cross-sectional study. SETTING: US tertiary care children's hospital. SUBJECTS AND METHODS: Seventy pediatric patients undergoing tympanostomy tube placement were preoperatively imaged using an OCT otoscope. A blinded reader quiz was conducted using 24 readers from 4 groups of tiered medical expertise. The primary outcome assessed was reader ability to detect presence/absence of MEE. A secondary outcome assessed was reader ability to differentiate serous vs nonserous MEE. RESULTS: OCT image data sets were analyzed from 45 of 70 total subjects. Blinded reader analysis of an OCT data subset for detection of MEE resulted in 90.6% accuracy, 90.9% sensitivity, 90.2% specificity, and intra/interreader agreement of 92.9% and 87.1%, respectively. Differentiating MEE type, reader identification of nonserous MEE had 70.8% accuracy, 53.6% sensitivity, 80.1% specificity, and intra/interreader agreement of 82.9% and 75.1%, respectively. Multivariate analysis revealed that age was the strongest predictor of OCT quality. The mean age of subjects with quality OCT was 5.01 years (n = 45), compared to 2.54 years (n = 25) in the remaining subjects imaged (P = .0028). The ability to capture quality images improved over time, from 50% to 69.4% over the study period. CONCLUSION: OCT otoscopy shows promise for facilitating accurate MEE detection. The imageability with the prototype device was affected by age, with older children being easier to image, similar to current ear diagnostic technologies.

Cost Analysis of a Multidisciplinary Vascular Anomaly Clinic.

OBJECTIVE: Multidisciplinary vascular anomaly clinics (VACs) offer important value to pediatric patients with complex vascular anomalies whose care overlaps specialties. These clinics are labor intensive and costly to operate since providers see fewer patients compared to their individual specialty clinic. Our North American tertiary care institution's VAC specialists include a pediatric otolaryngologist, pediatric surgeon, pediatric plastic surgeon, pediatric dermatologist, and interventional radiologist. To assess financial feasibility, we conducted a cost analysis of our VACs comprised of 2 half-day multidisciplinary physician attended clinics (5 specialists at our main campus and 2 specialists at a satellite clinic) and a half-day nurse practitioner clinic. METHOD: Assessment of net revenue based on net collections for clinic, professional, operative, hospital setting, and facility charges generated during 12 consecutive monthly VACs beginning July 1, 2015. Expense calculations included provider and staff salaries, benefits, supply costs, and clinic leasing costs. RESULTS: There were 469 clinic visits, of which 202 were new patient evaluations. Sixty-eight patients underwent 93 procedures under general anesthesia, including procedures performed by our interventional radiologist, most commonly sclerotherapy or embolization (n = 37), surgical interventions including endoscopy (n = 36), or laser procedures (n = 20). Three patients were admitted. Fifty-seven patients received a new diagnosis different from that for which they were referred. Gross revenue was $1 810 525, and net revenue was 42.5%, or $783 152. Expenses totaled $453 415 for a net positive revenue of $329 737. CONCLUSION: When including direct downstream revenue, particularly from operative procedures, our VAC program operates on a net positive margin, making the program financially feasible.

Aerodigestive Approach to Chronic Cough in Children.

PURPOSE OF REVIEW: Chronic cough is the most common presenting complaint in a pediatric aerodigestive clinic. The etiology of chronic cough is varied and often includes more than one organ system. This review aims to summarize the current literature for a multidisciplinary approach when evaluating a child with chronic cough. RECENT FINDINGS: There is very little medical literature focused on a multidisciplinary approach to chronic cough. In the limited data available, multidisciplinary clinics have been shown to be more cost-efficient for the families of children with complex medical problems, and also increase the likelihood of successfully obtaining a diagnosis. SUMMARY: There is no consensus in the literature on how to work-up a child with chronic cough presenting to an aerodigestive clinic. Current studies from these clinics have shown improved outcomes related to cost-effectiveness and identifying definitive diagnoses. Future studies evaluating clinical outcomes are necessary to help delineate the utility of testing routinely performed, and to demonstrate the impact of interventions from each specialty on quality of life and specific functional outcome measures.

Is a Multidisciplinary Aerodigestive Clinic More Effective at Treating Recalcitrant Aerodigestive Complaints Than a Single Specialist?

OBJECTIVE: To determine the utility of a pediatric multidisciplinary aerodigestive clinic (ADC) in treating recalcitrant aerodigestive conditions. METHODS: Longitudinal observational study of presenting complaints, evaluation, management, and outcome of patients seen during 12 monthly ADCs beginning August 2013. RESULTS: Fifty-five patients were seen by the ADC team (otolaryngology/gastroenterology/pulmonology/speech pathology/nurse practitioner) and followed for a mean 17.6 months (range, 12-26 months). Mean age was 4.3 years (range, 0.5-19 years). All were seen by at least 1 specialist before ADC referral but without significant improvement. Chronic cough was the most common primary symptom (44%). Clinic evaluation included flexible nasopharyngolaryngoscopy (FFL, 53%) and pulmonary function testing (36%.) FFL influenced management in 79%. An operative procedure usually combined endoscopy was warranted in 58%. Endoscopy provided high diagnostic yield, detecting laryngeal cleft (8), adenoid hypertrophy (8), vocal cord dysfunction (4), pulmonary infection (4), reflux disease (3), laryngomalacia (3), tracheomalacia (2), cilia abnormality (2), celiac disease (1), Helicobacter pylori (1), duodenal web (1), and eosinophilic esophagitis (1). Outcome was available for 48 of 55 patients, with 73% reporting resolved to markedly improved symptoms and 27% minimal to no improvement. CONCLUSIONS: The ADC team approach resulted in resolved to markedly improved symptoms in 73% of patients whose symptoms persisted despite seeing a single specialist prior to referral.

Functional changes in children, adolescents, and young adults with cerebral palsy.

Children with multiple handicaps, including cerebral palsy (CP), often lose or regress in their functional ability through adolescence and adulthood. The purpose of this study was to examine functional and psychological changes in children, adolescents and young adults with CP. A retrospective chart review and a prospective telephone interview of 30 patients (11-29 years, M = 16.8, S.D. = 4.9) was conducted. Seventy-three percent of the patients were male (n = 22) and 83% (n = 25) had spastic CP. According to the McNemar's test, four significant functional losses were found including crawling (p = 0.03), standing independently (p = 0.05), walking with or without assistance (p = 0.014), and eating by mouth (p = 0.01). Standing function loss was significantly related to walking function loss (p = 0.02). Sixty-three percent (n = 19) of the patients experienced anxiety and 10% (n = 3) reported depression. Results of this study indicate that a validated yearly assessment tool is needed to measure functional and emotional changes in children with CP rather than relying on parent recall. This data may also lead to a review of the current physical therapy national standards.
