RESUMO

Introduction Despite several pediatric tracheostomy decannulation protocols there remains tremendous variability in practice. The effect of tracheostomy capping on decannulation has been studied but the role of speaking valves (SVs) is unknown. Objective Given the positive benefits SVs have on rehabilitation, we hypothesized that SVs would decrease time to tracheostomy decannulation. The purpose of the present study was to evaluate this in a subset of patients with chronic lung disease of prematurity (CLD). Methods A retrospective chart review was performed at a tertiary care children's hospital. A total of 105 patients with tracheostomies and CLD were identified. Data collected included demographics, gestational age, congenital cardiac disease, airway surgeries, granulation tissue excisions, SV and capping trials, tracheitis episodes, and clinic visits. Statistics were performed with logistic and linear regression. Results A total of 75 patients were included. The mean gestational age was 27 weeks (standard deviation [SD] = 3.6) and the average birthweight was 1.1 kg (SD = 0.6). The average age at tracheostomy was 122 days (SD = 63). A total of 70.7% of the patients underwent decannulation and the mean time to decannulation (TTD) was 37 months (SD = 19). A total of 77.3% of the patients had SVs. Those with an SV had a longer TTD compared to those without (52 versus 35 months; p = 0.008). Decannulation was increased by 2 months for every increase in the number of hospital presentations for tracheitis ( p = 0.011). Conclusion The present study is the first, to our knowledge, to assess the effect of SVs on tracheostomy decannulation in patients with CLD showing a longer TTD when SVs are used.

RESUMO

BACKGROUND: There has been little investigation regarding air quality and rhinitis in the pathophysiology of upper airway disease. In this study, we assessed the impact of inhalant pollutants (particulate matter 2.5 [PM2.5 ] and black carbon [BC]) on allergic rhinitis and chronic rhinosinusitis (CRS) disease severity. METHODS: CRS patients with nasal polyps (CRSwNP) and without polyps (CRSsNP) were identified. Spatial modeling from pollutant monitoring sites was used to estimate exposures for patients meeting the inclusion criteria (total, n = 125; CRSsNP, n = 67; CRSsNP, n = 58). Skin-prick, intradermal dilutional, and in-vitro testing methods were utilized to determine aeroallergen sensitization. Disease severity indicators were measured by modified Lund-Mackay score (LMS), the 22-item Sino-Nasal Outcome Test (SNOT-22), systemic steroid therapy, and number of functional endoscopic sinus surgeries (FESS). RESULTS: Thirty-six percent (n = 45) of patients who described rhinitis symptoms demonstrated no reactivity to aeroallergen testing. Sixty-four percent (n = 80) tested positive for at least 1 allergen, with no differences found between CRSsNP and CRSwNP (62.1% vs 67.2%). There were significant differences in air pollutants between patients testing negative and positive for allergies (nonallergic vs allergic: PM2.5 , 11.32 vs 11.07 µg/m3 , p = 0.030; BC, 0.81 vs 0.76 absorbance, p =0.044). Nonallergic CRSwNP demonstrated higher PM2.5 compared with allergic counterparts (11.48 vs 11.09 µg/m3 , p = 0.032). A similar pattern was observed with BC (0.82 vs 0.75 absorbance, p = 0.017). In CRSsNP, BC correlated significantly with SNOT-22 (r = 0.55, p = 0.042). CONCLUSION: Our results suggest that small inhalant pollutants may contribute to nonallergic symptomatology in patients with and without nasal polyps. Regardless of allergy status, BC may play a role in CRS symptom severity.

RESUMO

BACKGROUND: Skin-prick testing (SPT), in vitro testing (IVT), and intradermal-dilutional testing (IDT) are methods to detect patient sensitivities to specific allergens and direct immunotherapy dosing. We used objective and subjective measures of improvement to compare outcomes based on test method. METHODS: Patients underwent 1 of 3 protocols: SPT, screening SPT followed by IDT, or IVT. We used institution billing data to do a cost analysis of these tests. The time to maintenance (TTM) therapy was analyzed and patients were stratified into high and low reactors. The Rhinoconjunctivitis Quality of Life Questionnaire (RQLQ) was used to quantify symptoms pre-maintenance and post-maintenance. RESULTS: Of 177 patients (SPT, n = 40; IVT, n = 91; IDT, n = 46), 115 (SPT, n = 35; IVT, n = 39; IDT, n = 41) were high reactors. Out of 90 patients (SPT, n = 17; IVT, n = 37; IDT, n = 36) reaching maintenance, 58 were high reactors (SPT, n = 15; IVT, n = 12; IDT, n = 31). Overall, SPT, IVT, and IDT median TTM were 542, 329, and 578.5 days, respectively. IDT TTM was shorter compared to IVT overall and in high reactors (hazard ratio [HR] = 1.91, p = 0.02; HR = 2.12, p = 0.03), but was not significant compared to SPT high reactors (p = 0.33). The IDT cost was $62.66, translating to an incremental cost-effectiveness ratio of $0.23 per day of shortened TTM. Median RQLQ change for the SPT, IVT, and IDT groups was 6.5, 1, and 1.5, respectively, but was not significant (p = 0.60). CONCLUSION: IDT reached maintenance immunotherapy quicker than IVT but there was no difference compared to SPT. TTM did not correlate with improvements in patient symptoms between testing methods. This study represents a novel comparison of outcomes based on initial allergy testing method.
