Assessing outcomes after partial and total tonsillectomy for sleep-disordered breathing in children using Clinical Assessment Score-15.

INTRODUCTION: The Clinical Assessment Score-15 (CAS-15) is an office-based tool for assessing the risk of sleep disordered breathing (SDB), a relatively common condition in the pediatric population. Change in CAS-15 following total tonsillectomy (TT) has been shown to have a large effect size, but it is unclear how it varies following partial intracapsular tonsillectomy (PIT). Thus, the objective of the present study is to evaluate the utility of the CAS-15 score in assessing the effectiveness of PIT and how this compares to change after TT. MATERIAL METHODS: Children ages 2-18 undergoing PIT (N = 16) or TT (N = 8) with or without adenoidectomy for SDB completed the CAS-15 before surgery and at their post-operative follow-up visit. Changes in CAS-15 score were assessed by paired t-test. The mean difference in CAS-15 change between PIT and TT was evaluated by unpaired t-test for unequal variances. Differences in participant characteristics were determined via unpaired t-test for unequal variances. RESULTS: Participants undergoing PIT did not differ significantly than those undergoing TT with regard to age, sex, BMI percentile, pre-op CAS-15 score or tonsil size, or admission rates following surgery (p > 0.05). The median follow-up after surgery was 5.2 (PIT) and 4.4 (TT) weeks. CAS-15 score improved significantly following PIT (42.8 ± 12.3 vs. 9.4 ± 5.6, p < 0.0001) and TT (45.5 ± 13.3 vs. 7.9 ± 5.8, p < 0.0002). The decrease in CAS-15 for PIT did not differ from TT (33.3 ± 11.8 vs. 37.6 ± 15.0, p > 0.49). DISCUSSION: CAS-15 decreases drastically following PIT and TT, indicating significant improvement of SDB symptoms. Because the change in CAS-15 after PIT was similar to TT, PIT may be preferred due to the decreased morbidity of the procedure. Given the cost, time required, inconvenience, and other limitations of overnight polysomnography (PSG), which is the gold standard method of diagnosing SDB, CAS-15 may be a suitable replacement or adjunct for the assessment of SDB following PIT in addition to TT.

Predictors of sinonasal disease onset, progression, and severity in pediatric cystic fibrosis patients.

PURPOSE: Pediatric cystic fibrosis (CF) patients have a variable onset, severity, and progression of sinonasal disease. The objective of this study was to identify genotypic and phenotypic factors associated with CF that are predictive of sinonasal disease, recurrent nasal polyposis, and failure to respond to standard treatment. METHODS: A retrospective case series was conducted of 30 pediatric patients with CF chronic rhinosinusitis with and without polyps. Patient specific mutations were divided by class and categorized into high risk (Class I-III) and low risk (Class IV-V). Severity of pulmonary and pancreatic manifestations of CF, number of sinus surgeries, nasal polyposis and recurrence, age at presentation to Otolaryngology, and Pediatric Sinonasal Symptom Survey (SN-5)/Sinonasal Outcome Test (SNOT-22) scores were examined. RESULTS: 27/30 patients (90%) had high risk mutations (Class I-III). 21/30 (70.0%) patients had nasal polyposis and 10/30 (33.3%) had recurrent nasal polyposis. Dependence on pancreatic enzymes (23/27, 85.2% vs 0/3, 0.0%, p = 0.009) and worse forced expiratory volumes (FEV1%) (mean 79, SD 15 vs mean 105, SD 12, p = 0.009) were more common in patients with high risk mutations. Insulin-dependence was more common in those with recurrent polyposis (5/10, 50% vs 2/20, 10%, p = 0.026). There was no statistical difference in ages at presentation, first polyps, or sinus surgery, or in polyposis presence, recurrence, or extent of sinus surgery based on high risk vs. low risk classification. CONCLUSION: CF-related diabetes was associated with nasal polyposis recurrence. Patients with more severe extra-pulmonary manifestations of CF may also be at increased risk of sinonasal disease.

Predictive Utility of the Penetration-Aspiration Scale in Inter-Arytenoid Injection Augmentation.

OBJECTIVES/HYPOTHESIS: To determine the utility of preoperative penetration-aspiration scale (PAS) scores and clinical findings on modified barium swallow (MBS) in predicting advancement of diet after interarytenoid injection augmentation (IAIA). STUDY DESIGN: Retrospective review. METHODS: In this retrospective cohort study, 372 consecutive patients who underwent IAIA for pharyngeal dysphagia between 2009 and 2019 were initially identified. Patients were excluded from the study if they had insufficient preop MBS, no postop MBS within 3 months of injection, supraglottoplasty, or underlying neurological condition. Ninety-three patients were included in the study. Pre- and postoperative PAS scores were recorded, as were pre and postop diets. PAS scores were calculated by a single pediatric speech and language pathologist. RESULTS: Average PAS score on MBS was 5.87 (standard deviation [SD] 2.74); median (range) = 8 (1-8). Postop average was 4.29 (SD 3.02); median (range) = 2 (1-8), P < .001. Those with worse preop PAS scores had increased odds of improvement in diet (odds ratio 1.24, 95% confidence interval [CI] 1.02-1.49, P = .029). An improvement in PAS score of 3.0 or greater predicted an improvement in diet with a sensitivity of 76.7% and a specificity of 85.7%. CONCLUSIONS: PAS score on MBS can be a useful tool when assessing pediatric patients who may be candidates for IAIA. Prospectively comparing PAS score in patients post-IAIA to patients solely undergoing diet modification can help to better objectively assess differences in outcomes and understand the full utility of PAS score.

Heterotopic gastric mucosa of the proximal esophageal (HGMPE) and its potential role in pediatric dysphonia and dysphagia.

OBJECTIVE: Despite a reported incidence of HGMPE of 10%, proof of acid production, and an increased incidence of respiratory symptoms, the pediatric otolaryngology, swallowing and voice care literature is silent on this entity. This case series describes pediatric patients confirmed to have HGMPE with dysphonia and/or dysphagia. METHODS: Retrospective case series of Pediatric Voice, Resonance, and Swallowing Center patients at a tertiary Children's Hospital in 2019. SETTING: Tertiary academic medical center. SUMMARY OF RESULTS: Three patients who underwent triple endoscopy for dysphonia or dysphagia were histologically diagnosed with HGMPE. Esophageal biopsies were otherwise normal. Two of the three patients resolved their primary aerodigestive symptoms following treatment with acid suppression and a protectant (sucralfate). The third patient reported significant improvement in symptoms by phone. The significance of this case series cannot be understated: 1) A need for increased awareness among pediatric otolaryngologists, voice care and swallowing professionals of this entity given its relatively common incidence of 10% offset by a dearth of presentations & scientific publications in our literature clearly exists. 2) Otolaryngologists have abandoned operative upper aerodigestive tract endoscopy in lieu of office-based less comprehensive videolaryngostroboscopy and fiberoptic endoscopic evaluation of swallowing. HGMPE & other esophageal disorders (i.e. eosinophilic esophagitis) support revisiting triple endoscopy in select patients where office endoscopy has failed to diagnose and successfully treat such patients. 3) Both acid suppression therapy and a protectant (sucralfate) may be useful in these patients. 4) Modification of rigid esophagoscopy technique to carefully assess the introitus and superior esophageal segment is paramount 5) Otolaryngologists over-diagnose & over-treat laryngopharyngeal reflux. The pediatric & adult literature is replete with significant safety warnings associated with acid suppression therapy and guidelines admonish their indiscriminate use, raising the liability bar of empiric treatment. Large scale prospective, randomized and controlled studies are needed to confirm the pathophysiologic role of this entity in pediatric aerodigestive disorders. CONCLUSION: HGMPE is a clinical entity that can be easily missed upon swift entry into the esophagus with rigid endoscopy. Careful scrutiny and visualization of the proximal esophagus is critical in order to identify HGMPE, as there is a higher rate of laryngospasm, stricture, and potentially neoplasm in this population.

Evaluating butterfly inlay tympanoplasty.

OBJECTIVE: To compare closure rate, reduction in air-bone-gap, and operative time of butterfly tympanoplasty (BT) to underlay tympanoplasty (UT). METHODS: Retrospective cohort study of children (age <18y) undergoing Type I tympanoplasty between 2009 and 2017. Patients were excluded if they had <6 months of follow up, mastoidectomy, fat graft or cholesteatoma. RESULTS: Twenty-one patients (mean age 13.4) underwent BT while forty-one patients (mean age 13.5) underwent UT. The mean size of perforation in 30.6% in BT patients and 43.6% in UT patients (p = 0.01). Preoperative audiogram showed a similar air-bone-gap between the two groups of 31.7, 22.7, and 17.9 dB in BT vs 29.6, 24.8, and 17.6 dB in UT at 500, 1000, and 2000 Hz, respectively (p = 0.65, 0.63, and 0.94). Operative time was reduced in BT as compared to UT (94.0 min vs. 150.9, p = 0.01). Closure rate was similar at 85.7% in BT vs 75.6% in UT patients (p = 0.40). Average reductions in air-bone gap were similar with 19.2, 11.7, and 13.2 dB for BT vs 16.6, 12.1, and 10.3 dB for UT at 500, 1000, and 2000 hz, respectively (p = 0.66, 0.93, 0.40). CONCLUSION: BT has become a reliable tool for the pediatric otolaryngologist. This retrospective study shows that pediatric BT results in similar outcomes with reduced operative time.

Pediatric Cervical Lymphadenopathy.

Cervical lymphadenopathy affects as many as 90% of children aged 4 to 8 years. With so many children presenting to doctors' offices and emergency departments, a systematic approach to diagnosis and evaluation must be considered. In the following review, we aim to provide the pediatric clinician with a general framework for an appropriate history and physical examination, while giving guidance on initial diagnostic laboratory testing, imaging, and potential need for biopsy. The most common cause of cervical lymphadenopathy in the pediatric population is reactivity to known and unknown viral agents. The second most common cause includes bacterial infections ranging from aerobic to anaerobic to mycobacterial infections. Malignancies are the most concerning cause of cervical lymphadenopathy.The explosion in the use of ultrasonography as a nonradiating imaging modality in the pediatric population has changed the diagnostic algorithm for many clinicians. We aim to provide some clarity on the utility and shortcomings of the imaging modalities available, including ultrasonography, computed tomography, and magnetic resonance imaging.

Bony/Cartilaginous Mismatch: A Radiologic Investigation into the Cause of Tension Nose Deformity.

BACKGROUND: Tension nose deformity is believed to be caused by an "oversized" septal quadrangular cartilage. Prior studies have shown that quadrangular cartilage size is relatively consistent in populations. The authors hypothesize that the tension nose deformity is actually caused by an external extrusion of a normal sized septal cartilage from an undersized bony septal encasement. METHODS: A retrospective case-control study of sagittal computed tomographic scans was conducted, measuring the perimeter and surface area of the quadrangular cartilage and bony septal aperture in tension nose cases and controls. Statistical analysis was performed. RESULTS: Of 23 patients enrolled in the study, 12 patients were sorted into the tension nose group, and 11 patients were considered controls. Both groups had similar perimeter and surface area of their quadrangular cartilage, without statistical difference between the two groups. However, the tension nose group had a statistically significant reduction in bony septal aperture perimeter compared with controls (p < 0.01) and a larger externally extruded septum compared with their internal septal size. They also had a substantially higher rate of septal deviation than controls. CONCLUSIONS: The results of this study suggest that a mismatch between a small bony septal aperture and a normal sized septal quadrangular cartilage may be responsible for caudal, upper lip, and dorsal fullness seen with the tension nose deformity caused by external extrusion of cartilage. Septal deviation may co-occur as a buckling phenomenon in a limited bony space. Surgical strategies to match the entire quadrangular cartilage size to the bony framework are suggested. CLINICAL QUESTION/LEVEL OF EVIDENCE: Risk, III.

Expression of antimicrobial peptides in the normal and involved skin of patients with infective cellulitis.

BACKGROUND: Endogenous antimicrobial peptides participate in the innate defense of skin against a variety of pathogens. The systemic expression of these peptides in normal-appearing skin of patients with infective cellulitis is unknown. METHODS: Study patients were adults with infective cellulitis and signs of systemic inflammation. Skin biopsy and serum specimens were obtained from patients and from control subjects with no active infection. Cathelicidin and human beta-defensin 2 mRNA expression were determined by real-time polymerase chain reaction. RESULTS: Skin biopsy specimens from 11 patients and 4 uninfected control subjects were analyzed. The relative expression level for cathelicidin mRNA was elevated in both the involved and the distal normal-appearing skin of patients with cellulitis, compared with expression in the skin of control subjects (mean ratios, 39.46 vs. 1.32, P=.0059; and 21.41 vs. 1.32, P=.0059). Similarly, the relative expression level of human beta -defensin 2 mRNA was elevated in both the involved skin (mean ratios, 20,844 vs. 11.65; P=.0015) and in distal normal-appearing skin of patients with cellulitis (mean ratios, 201.1 vs. 11.65; P=.0103). DISCUSSION: In response to cutaneous infection there is a local and distal increase in endogenous antimicrobial peptide mRNA in both involved and normal-appearing skin. These observations show, for the first time to our knowledge, that after infection the human body responds by increasing systemic innate immunity.
