RESUMO

Heart Failure with Preserved Ejection Fraction (HFpEF) is a major and common cardiovascular condition with widely variable clinical outcomes. Pulmonary hypertension (PH) often co-exists with HFpEF and tends to affect patient outcomes; this study aims to identify the impact of PH on the clinical outcome of patients admitted to the hospital with acute HFpEF exacerbations. We analyzed data from the National Inpatient Sample between 2016 and 2020, focusing on 464,438 acute HFpEF exacerbation hospitalizations. Outcomes were compared between those with PH (27.1 %) and those without PH (72.9 %). HFpEF hospitalizations with PH exhibited elevated in-hospital mortality (adjusted odds ratio [aOR]: 1.20, 95 % confidence interval [95 CI]: 1.08-1.31, P < 0.05), prolonged length of stay (adjusted ß: 0.90 days, P < 0.05), and increased overall costs (adjusted ß: $2,858, P < 0.05). Furthermore, HFpEF hospitalizations with PH demonstrated higher rates of atrial fibrillation, ventricular tachycardia, right ventricular failure, and conduction abnormalities. This population also displayed an increased incidence of acute hypoxic respiratory failure, necessitating increased non-invasive and mechanical ventilation. The co-existence of PH in HFpEF presents an increased risk of mortality and morbidity, with higher healthcare costs and the need for ventilatory support, in addition to higher risks of cardiovascular and pulmonary complications. Therefore, an early diagnosis of PH in patients with HFpEF is crucial, and further research is required to determine appropriate management.

RESUMO

Introduction Human papillomavirus-related (HPV + ) oropharyngeal squamous cell carcinoma (OPSCC) is increasing in incidence and presents diagnostic challenges given its unique clinical presentation. Objective The purpose of the present study is to characterize the impact of the unique clinical presentation of HPV-related OPSCC on delays in diagnosis. Methods Retrospective review of presenting symptoms and clinical characteristics of 284 patients with OPSCC treated from 2002-2014. Delay in diagnosis was defined as the presence of any of the following: multiple non-diagnostic fine needle aspirate (FNA) biopsies; two or more courses of antibiotic therapy; surgery with incorrect preoperative diagnosis; evaluation by an otolaryngologist without further workup; or surgery without definitive postoperative diagnosis. Results p16+ tumors demonstrated a distinct clinical presentation that more commonly involved a neck mass (85.1% versus 57.3% of p16-; p < 0.001) and less frequently included odynophagia (24.6% versus 51.7% of p16-; p < 0.001). Patients who experienced diagnostic delay were more likely to have p16+ tumors (77.7% delayed versus 62.8% not delayed; p = 0.006). p16+ primary tumors were more likely to be undetectable by physical examination of the head and neck including flexible laryngoscopy (19.0% versus 6.7% of p16-; p = 0.007) and more frequently associated with nondiagnostic FNA biopsies of a cervical nodal mass (11.8% versus 3.4% of p16-, p = 0.03). Conclusions Compared with non-HPV related OPSCC, the unique clinical presentation and characteristics of HPV+ OPSCC are associated with an increased incidence of diagnostic delay. Targeted education of appropriate care providers may improve time to diagnosis and treatment.

RESUMO

Background: Hypoglossal-facial nerve (12-7) anastomosis can restore symmetry and voluntary movement on the face in patients with facial nerve paralysis. Traditional 12-7 transfer includes direct end-to-end nerve anastomosis, sacrificing the entire hypoglossal nerve. Contemporary, end-to-side anastomosis, or split anastomosis techniques limit tongue morbidity by preserving some hypoglossal nerve. Direct outcome comparisons between these techniques are limited. Objective: To compare reported outcomes of facial movement, tongue, speech, and swallow outcomes among the different types of hypoglossal-facial nerve anastomosis schemes. Evidence Review: For this systematic review and meta-analysis, a comprehensive strategy was designed to search PubMed, Scopus, and the Cochrane Database from inception to January 2021, in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analysis, reporting guideline yielding 383 results. Any participant who underwent 12-7 transfer using any of the three techniques, with or without an interposition graft, and had documented preoperative and postoperative evaluation of facial nerve function with a validated instrument such as House-Brackmann (HB), was considered for inclusion. Secondary outcomes of synkinesis, tongue atrophy, and speech or swallowing dysfunction were also compared. Forty-nine studies met inclusion criteria, representing data from 961 total patients who underwent 12-7 transfer. Results: The proportion of good HB outcomes (HB I-III) did not differ by anastomosis type: End-to-side and end-to-end anastomosis (73% vs. 59%, p = 0.07), split and end-to-end anastomosis (62% vs. 59%, p = 0.88), and end-to-side anastomosis and split anastomosis (73% vs. 62%, p = 0.46). There was no difference in reported synkinesis rates between the anastomosis types. However, end-to-side anastomosis (z = 6.55, p < 0.01) and split anastomosis (z = 3.58, p < 0.01) developed less tongue atrophy than end-to-end anastomosis. End-to-side anastomosis had less speech/swallowing dysfunction than end-to-end anastomosis (z = 3.21, p < 0.01). Conclusion: End-to-side and split anastomoses result in similar HB facial nerve outcomes as the traditional end-to-end 12-7 anastomosis. End-to-side anastomosis has decreased complications of tongue atrophy and speech/swallow dysfunction compared to end-to-end anastomosis. In addition, split anastomosis has decreased rates of tongue atrophy compared to end-to-end anastomosis.

RESUMO

OBJECTIVE: The objective of this study is to describe an in vivo rabbit phonation model for glottic insufficiency that is simple and reproducible by means of unilateral transcricothyroid laryngeal muscle stimulation and high-speed video recordings of evoked phonation. STUDY DESIGN: Nonrandomized controlled animal trial. SETTING: Academic medical center. METHODS: A single operation including evoked phonation with bilateral and unilateral transcricothyroid laryngeal muscle stimulation conditions was modeled using 6 New Zealand white rabbits. The effect of stimulation method on glottic cycle, pitch, and loudness was compared. Endoscopic recordings using 5000 frames-per-second image capture technology and audiologic recordings were obtained for all phonation conditions. Primary outcome measures included means of maximum glottal area (MGA)/length pixel ratio, right and left amplitude/length pixel ratios, calculated cycle frequency, auditory recorded frequency, and maximum auditory intensity. Measurements were obtained via pixel counts using ImageJ. RESULTS: Mean MGA/length was significantly greater with unilateral, 20.30, vs bilateral, 9.62, stimulation (P = .043). Mean frequency of 479.92 Hz vs 683.46 Hz (P = .027) and mean maximum intensity of 76.3 dB vs 83.5 dB (P = .013) were significantly increased from unilateral to bilateral stimulation. There was no significant difference in mean right amplitude/length between unilateral and bilateral. CONCLUSION: The described model demonstrates a simple and reproducible means of producing glottic insufficiency due to unilateral vocal fold bowing and represents a pathway for better understanding the biomechanics and pathophysiology of glottic insufficiency due to superior laryngeal nerve injury and vocal fold immobility and offers the potential to compare treatment modalities through in vivo study.

RESUMO

INTRODUCTION: The standard complete evaluation of patients with head and neck squamous cell carcinoma (HNSCC) has included a staging exam under anesthesia (EUA) since the 1970s. The EUA for all sites of HNSCC has historically consisted of panendoscopy for the purpose of diagnostic biopsy, accurate staging of primary disease, and identification of second primary tumors. However, due to the accessibility of the oral cavity, the sole purpose of EUA for tumors of this site is to identify second primary tumors. Since the EUA became the gold standard for evaluation of HNSCC, there have been significant advancements in less invasive technologies such as CT, PET-CT, MRI, and fiberoptic examination. In this study, we sought to determine the value to patient care and cost-effectiveness of EUA in patients with oral cavity squamous cell carcinoma (OCSCC). METHODS: A retrospective chart review identified 77 patients who underwent EUA for OCSCC. RESULTS: The most common subsites were the oral tongue and floor of mouth (59.7% and 24.7% respectively). All underwent direct laryngoscopy, 94.8% underwent esophagoscopy, and 20.8% underwent flexible transnasal examination in clinic prior to EUA. For 90.9% of patients, the EUA did not change initial T-staging based on clinical examination and imaging. The remaining 9.1% of patients were upstaged after EUA, however this change did not impact the treatment plan. Second primary tumors were identified in 3.9% of patients, all were found in either the oral cavity or oropharynx, and were also identified with clinical examination or imaging. Analysis of patient charges determined an average cost of $8,022.93 per patient under the current paradigm involving EUA, however with a new algorithm eliminating mandatory EUA average cost decreases to $1,448.44. CONCLUSION: Formal EUA has historically been the gold standard for all HNSCC tumors. However, when performed for cases of oral cavity carcinoma, it is safe and cost effective to limit its use to select clinical scenarios.

RESUMO

OBJECTIVE: To analyze tweets associated with Ménière's disease (MD), including type of users who engage, change in usage patterns, and temporal associations, and to compare the perceptions of the general public with healthcare providers. METHODS: An R-program code, academictwitterR API, was used to query Twitter. All tweets mentioning MD from 2007 to 2021 were retrieved and analyzed. Valence Aware Dictionary and Sentiment Reasoning was used as a model to assess sentiment of tweets. Two reviewers assessed 1,007 tweets for qualitative analysis, identifying the source and the topic of the tweet. RESULTS: A total of 37,402 tweets were analyzed. The number of tweets per user ranged from 1 to 563 (M = 33.7, SD = 91.1). Quantitative analysis showed no temporal or seasonal association; however, tweeting increased when celebrities were diagnosed with MD. Of the 1007 representative tweets analyzed, 60.6% of tweets came from the general public and were largely of negative sentiment focusing on quality of life and support, whereas healthcare providers accounted for 23% of all tweets and focused on treatment/prevention. Tweets by news sources accounted for the remaining 13% of all tweets and were primarily positive in sentiment and focused on awareness. CONCLUSIONS: MD is commonly tweeted about by the general public, with limited input regarding the disease from healthcare providers. Healthcare providers must provide accurate information and awareness regarding MD, especially when awareness is highest, such as when celebrities are diagnosed.

RESUMO

BACKGROUND: The purpose of this review article is to summarize the existing literature surrounding wound healing mechanisms in laryngotracheal stenosis. METHODS: A review of general wound healing pathophysiology, followed by a focused review of iatrogenic laryngotracheal stenosis (iLTS) and idiopathic subglottic stenosis (iSGS) as conditions of aberrant wound healing. RESULTS: iLTS is the scarring of the laryngotracheal complex, coming secondary to injury from prolonged intubation. iSGS is a chronic fibroinflammatory scarring and narrowing of the subglottic airway in the absence of any obvious preceding injury or trauma. They are both thought to result from a prolonged and dysregulated wound healing response that promotes the deposition of pathologic scar in the airway. CONCLUSIONS: Understanding the mechanisms that underlie wound healing will help identify and intervene on the process early in its development and discover future therapies that target individual wound healing mechanisms limiting the incidence of this recalcitrant disease process.

RESUMO

BACKGROUND: This study aims to identify the strongest predictor of postoperative hypocalcemia following thyroid surgery. METHODS: Study of patients who underwent total/completion thyroidectomy. No patients received postoperative calcium supplementation. Demographic and perioperative data were collected including preoperative baseline parathyroid hormone (PTH) levels, PTH levels at 30 min and 6 h post-excision, and 18 h post-excision calcium levels. RESULTS: Of 124 patients studied, 20.2% developed temporary hypocalcemia (Ca <8.5 mg/dL at 18 h post-excision). In multivariate analyses, absolute PTH levels at 30 min and 6 h post-excision as well as change in PTH from baseline at 30 min and 6 h post-excision were statistically significantly associated with postoperative hypocalcemia. Per 10 units decrease in PTH from baseline at 30 min post-excision, the risk of developing temporary hypocalcemia increases by 17%. CONCLUSION: Absolute PTH levels and change in PTH from baseline at 30 min and 6 h post-excision predict hypocalcemia after total or completion thyroidectomy.

RESUMO

OBJECTIVE: Vocal fold paresis or paralysis (VFP) may severely affect quality of life due to dysphonia and respiratory distress. As an increasing percentage of the United States population receives the COVID-19 vaccination, the objective of this study is to determine the correlation of COVID-19 postvaccination recurrent laryngeal neuropathy and resulting VFP. METHODS: The Vaccine Adverse Event Reporting System database was queried for patients exhibiting symptoms of VFP following COVID-19 vaccination. Patient demographics and clinical information including presenting symptoms, time of symptom onset, time of diagnosis and laterality. RESULTS: Twenty patients were found to have laryngoscopy confirmed VFP following COVID-19 vaccination. Vaccinations for Pfizer-BioNTech, Moderna, and Janssen were reported. Of those reported, 13 patients were female (65.0%) and seven were male (35.0%), with a mean age of 61.8 years. The most common presenting symptom was a hoarse voice (30.0%). A majority of these cases were unilateral in nature (64.0%). Mean time from vaccination to symptom onset was 12.1 days and mean time from vaccination to diagnosis was 37.6 days. CONCLUSION: For patients presenting with voice or swallowing complaints after receiving the COVID-19 vaccine, prompt evaluation by an otolaryngologist should occur. However, the potential VFP side effect of vaccination is very rarely cited in the literature and largely outweighed by the benefits of vaccination. Further research is needed to delineate the exact pathophysiology of this complication and determine whether a causal relationship exists.

RESUMO

OBJECTIVES/HYPOTHESIS: The purpose of this study is to develop consensus on key points that would support the use of systemic bevacizumab for the treatment of recurrent respiratory papillomatosis (RRP), and to provide preliminary guidance surrounding the use of this treatment modality. STUDY DESIGN: Delphi method-based survey series. METHODS: A multidisciplinary, multi-institutional panel of physicians with experience using systemic bevacizumab for the treatment of RRP was established. The Delphi method was used to identify and obtain consensus on characteristics associated with systemic bevacizumab use across five domains: 1) patient characteristics; 2) disease characteristics; 3) treating center characteristics; 4) prior treatment characteristics; and 5) prior work-up. RESULTS: The international panel was composed of 70 experts from 12 countries, representing pediatric and adult otolaryngology, hematology/oncology, infectious diseases, pediatric surgery, family medicine, and epidemiology. A total of 189 items were identified, of which consensus was achieved on Patient Characteristics (9), Disease Characteristics (10), Treatment Center Characteristics (22), and Prior Workup Characteristics (18). CONCLUSION: This consensus statement provides a useful starting point for clinicians and centers hoping to offer systemic bevacizumab for RRP and may serve as a framework to assess the components of practices and centers currently using this therapy. We hope to provide a strategy to offer the treatment and also to provide a springboard for bevacizumab's use in combination with other RRP treatment protocols. Standardized delivery systems may facilitate research efforts and provide dosing regimens to help shape best-practice applications of systemic bevacizumab for patients with early-onset or less-severe disease phenotypes.

RESUMO

OBJECTIVE: The mechanism by which recurrent croup occurs is unknown. Gastroesophageal reflux is commonly implicated, although this relationship is only loosely documented. We conducted a systematic review with a meta-analysis component to evaluate the relationship between recurrent croup and gastroesophageal reflux disease (GERD), and to assess for evidence of improvement in croup symptoms when treated. STYLE DESIGN: Systematic Review and Meta Analysis. METHODS: We searched five separate databases. Studies were included if they discussed the relationship between croup and GERD in children, >5 subjects, and available in English. Literature retrieved was assessed according to pre-specified criteria. Retrieved articles were reviewed by two independent authors and decisions mediated by a third author. If there was a difference of opinion after first review, a second review was performed to obtain consensus. Heterogeneity was calculated and summarized in forest plots. RESULTS: Of 346 initial records, 15 met inclusion criteria. These were two retrospective cohort and 13 cross-sectional studies. Thirteen of 15 articles support an association between recurrent croup and GERD. Although heterogeneity is high among studies that reported prevalence of GERD, there is less uncertainty in results for improvement to recurrent croup after GERD treatment. Most studies lacked a control group and all carry a moderate-to-high risk of bias. CONCLUSION: There is limited evidence linking GERD to recurrent croup; Further research is needed to assess for causality as most studies are retrospective, lack a control group, and have a study design exposing them to bias. Patients treated with reflux medication appear to demonstrate a reduced incidence of croup symptoms. LEVEL OF EVIDENCE: 1 Laryngoscope, 131:209-217, 2021.

RESUMO

OBJECTIVE: (1) To describe characteristics associated with tracheostomy placement and (2) to describe associated in-hospital morbidity in extremely premature infants. STUDY DESIGN: Pooled retrospective analysis of charts. SETTING: Academic children's hospitals. SUBJECTS AND METHODS: The patient records of premature infants (23-28 weeks gestational age) who underwent tracheostomy between January 1, 2012, and December 31, 2017, were reviewed from 4 academic children's hospitals. Demographics, procedural morbidity, feeding, respiratory, and neurodevelopmental outcomes at the time of transfer from the neonatal intensive care unit (NICU) were obtained. The contribution of baseline characteristics to mortality, neurodevelopmental, and feeding outcomes was also assessed. RESULTS: The charts of 119 infants were included. The mean gestational age was 25.5 (95% confidence interval, 25.2-25.7) weeks. The mean birth weight was 712 (671-752) g. Approximately 50% was African American. The principal comorbidity was chronic lung disease (92.4%). Overall, 60.5% of the infants had at least 1 complication. At the time of transfer, most remained mechanically ventilated (94%) and dependent on a feeding tube (90%). Necrotizing enterocolitis increased the risk of feeding impairment (P = .002) and death (P = .03). CONCLUSIONS: Tracheostomy in the extremely premature neonate is primarily performed for chronic lung disease. Complications occur frequently, with skin breakdown being the most common. Placement of a tracheostomy does not seem to mitigate the systemic morbidity associated with extreme prematurity.

RESUMO

We report on two cases of severe recurrent respiratory papillomatosis (RRP) involvement where the anti-vascular endothelial growth factor (VEGF) antibody bevacizumab IV has been administered for treatment. Notably, there have not been any episodes of urgent transfer to the hospital for obstructive events since the bevacizumab was started. It is important to note however, that the disease has not been eliminated. While some pulmonary nodules continue to grow, they have become cavitated. Overall, the number and size of pulmonary lesions has decreased. Therefore, VEGF-targeted therapies, Bevacizumab, could prove to be a promising novel approach for long-term treatment of severe RRP.

RESUMO

AIM: To evaluate the effect of varying cellulose casting ring liner length and its prewetting on the marginal adaptation and dimensional accuracy of full veneer metal castings. MATERIALS AND METHODS: The master die was milled in stainless steel to fabricate the wax pattern. Sixty wax patterns were fabricated with a uniform thickness of 1.5 mm at an occlusal surface and 1 mm axial surface, cervical width at 13.5 mm, and 10 mm cuspal height. The samples were divided into six groups (n = 10). Groups I and II samples had the full-length cellulose prewet and dry ring liner, respectively. The groups III and IV had 2 mm short prewet and dry cellulose ring liner, respectively, whereas groups V and VI were invested in 6 mm short ring liner. The wax patterns were immediately invested in phosphate bonded investment, and casting procedure was completed with nickel-chrome alloy. The castings were cleaned and mean score of measurements at four reference points for marginal adaption, casting height, and cervical width was calculated. The marginal adaption was calculated with Imaje J software, whereas the casting height and cervical width was determined using a digital scale. The data was subjected to one-way analysis of varaince and Tukey post hoc statistical analysis with Statistical Package for the Social Sciences version 20 software. RESULTS: The group II had the best marginal adaption with a gap of 63.786 µm followed by group I (65.185 µm), group IV (87.740 µm), and group III (101.455 µm). A large marginal gap was observed in group V at 188.871 µm. Cuspal height was more accurate with group V (10.428 mm), group VI (10.421 mm), and group II (10.488 mm). The cervical width was approximately similar in group I, group III, and group V. Statistically significant difference was observed in Tukey post hoc analysis between group V and group VI with all the other groups with regards to marginal adaptation. CONCLUSION: The dry cellulose ring liners provided better marginal adaptation in comparison to prewet cellulose ring liners. Accurate cuspal height was obtained with shorter ring liner in comparison to full-length cellulose ring liners.
