Objectives:Predicting response to proton pump inhibitor (PPI) therapy in patients with laryngeal symptoms is challenging. The Restech Dx-pH probe is a transnasal catheter that measures oropharyngeal pH. In this study, we aimed to investigate the prognostic potential of oropharyngeal pH monitoring to predict responsiveness to PPI therapy in patients with laryngeal symptoms.Methods:We conducted a physician-blinded prospective cohort study at a single academic institution between January 2013 and October 2014. Adult patients with Reflux Symptom Index scores (RSI) ≥13 off PPI therapy were recruited. Patients underwent video laryngoscopy and 24-h oropharyngeal pH monitoring, followed by an 8- to 12-week trial of omeprazole 40 mg daily. Prior to and following PPI therapy, patients completed various symptom questionnaires. The primary outcome was the association between PPI response and oropharyngeal pH metrics. PPI response was separated into three subgroups based on the post-treatment RSI score and % RSI response: non-response=RSI ≥13; partial response=post-treatment RSI <13 and change in RSI <50%; and complete response=post-treatment RSI <13 and change in RSI ≥50%. The primary analysis utilized a multinomial logistic regression controlling for the pre-treatment RSI score. A secondary analysis assessed the relationship between the change in RSI (post–pre) and oropharyngeal pH metrics via ordinary least square regression.Results:Thirty-four patients completed the study and were included in final analysis. Symptom response to PPI therapy was as follows: 50% no response, 15% partial response, and 35% complete response. Non-responders had a higher pre-treatment RSI (P<0.01). There were no significant differences in oropharyngeal acid exposure (below pH of 4.0, 5.0, 5.5, 6.0, and RYAN scores) between responder types. The secondary analysis noted a trend between lower PPI response and a greater total percent time below pH of 5.0 (P=0.03), upright percent time below pH of 5.0 (P=0.07), and RYAN supine (corrected; P=0.03), as well as an association between PPI response and greater decreases in the Anxiety Sensitivity Inventory (P<0.01), Brief Symptom Inventory-18 (P<0.01), and Negative Affect Scale (P<0.01).Conclusions:Oropharyngeal pH testing did not predict laryngeal symptom response to PPI therapy. Contrary to hypothesis, our study signaled that the degree of oropharyngeal acid exposure is inversely related to PPI response. In addition, reduction in negative affect and psychological distress parallels PPI response.

Responsiveness, or sensitivity to clinical change, is important when selecting patient‐reported outcome measures (PROMs) for research and clinical applications. This study compares responsiveness of PROMs used in chronic rhinosinusitis (CRS) to inform the future development of a highly responsive instrument that accurately portrays CRS patients’ symptom experiences.

Chronic rhinosinusitis (CRS) is a common condition encountered in primary care medicine and is estimated to affect 12.5% of the United States population. This study aims to compare methods of assessing health utility in CRS.

The safety of alternative vitamin K antagonist (VKA) reversal strategies in patients with left ventricular assist devices (LVAD’s) who present with intracranial hemorrhage (ICH) are not well known. A review of LVAD patients with ICH from May 2008 to 2015 was conducted, comparing the safety and efficacy of 4-factor prothrombin complex concentrate-assisted VKA reversal (4F-PCC group, n = 10) to reversal with traditional agents alone (no-PCC group, n = 10). An analysis of a no-reversal strategy in selected patients (n = 11) with ICH was additionally performed. Thirty-one cases of ICH on LVAD support were reviewed. The rate of post reversal thromboembolic events was not significantly different between 4F-PCC and no-PCC patients (0% vs. 10%, p = 1.0); however, the time to VKA reversal was shorter (474 vs. 945 minutes, p = 0.02) and fresh frozen plasma (FFP) requirements lower (1.9 vs. 3.6 units, p = 0.05) in 4F-PCC patients, with no difference in mortality between groups (p = 1.0). Eleven patients (mean ICH volume: 0.4 cm3) were successfully managed without active VKA reversal, with no increased hemorrhage noted on neuroimaging. These results suggest that 4F-PCC-assisted reversal in LVAD patients is safe and may improve the efficacy of VKA reversal. Our findings also indicate that carefully selected patients with small ICH volumes may be safely managed by discontinuing anticoagulation and allowing the international normalized ratio (INR) to normalize physiologically.

Various intranasal landmarks have been described to aid in the localization of the natural sphenoid sinus ostium. The objectives of this study are to identify the ostium location relative to the skull base and assess the relationships between the location of the ostium and sphenoid disease or pneumatization pattern.

Objectives: Open chest management (OCM) is an important intervention for patients who are unable to undergo sternal closure after cardiac surgery. This study reviews the factors associated with a prolonged need for this intervention and investigates its association with early and late mortality. Methods: Patients undergoing OCM from January 2009 to December 2014 were reviewed. Differences in the median duration of OCM when a perioperative variable was present versus its absence were determined and variables significant at P ≤ .1 were analyzed using Poisson regression for factors associated with prolonged OCM. Multivariable logistic regression and Cox proportional hazards models were developed to investigate perioperative factors that were associated with early and late mortality. Results: A total of 201 patients (5%) required OCM and the overall median duration of this intervention was 3 days. The use a temporary assist device (median, 7 vs 2 days; P < .001), pneumonias (median, 11 vs 3 days; P < .001), sternal re‐explorations (median, 6 vs 2 days; P < .001), and renal failure (median, 6 vs 3 days; P = .02) were among the factors that were highly associated with prolonged OCM using Poisson regression. Thirty‐day mortalities occurred in 32 patients (16%) and were significantly associated with emergency surgery (P = .03), sternal re‐explorations (P = .001), and OCM duration (median, 6 vs 3 days; P = .02). On multivariable logistic regression and Cox analysis, delaying sternal closure by 1‐day increments increased the risk of early and late mortality by 11% (P = .01), and 9% (P < .001), respectively. Conclusions: Prolonged OCM was associated with increasing perioperative morbidity and a higher risk of early and late mortality.

Chronic rhinosinusitis with nasal polyps (CRSwNP) has a high propensity for recurrence. Studies suggest that eosinophilia influences disease severity and surgical outcomes, but the selection of sinonasal site for measuring eosinophilia has not been examined. The aim of this study was to investigate how region‐specific tissue eosinophilia affects radiographic severity, comorbidity prevalence, and polyp recurrence risk following sinus surgery.
