RESUMEN

Solitary plasmacytoma is a rare neoplasm characterized by localized proliferation of monoclonal plasma cells and is classified as solitary bone or solitary extramedullary plasmacytoma. Here, we present two rare cases of plasmacytoma of the head and neck. The first is a 78-year-old male who presented with a 3-month history of epistaxis and progressive obstruction of the right nasal passage. Computerized tomography (CT) imaging revealed a mass in the right nasal cavity with destruction to the maxillary sinus. An excisional biopsy was performed revealing anaplastic plasmacytoma. The second is a 64-year-old male with a past medical history significant for prostate cancer who presented with a 2-month history of left ear pain and progressive non-tender temporal swelling. A PET/CT revealed a highly avid, destructive, and lytic left temporal mass with no other evidence of distant disease. A left temporal craniectomy and infratemporal fossa dissection revealed plasma cell dyscrasia with monoclonal lambda in situ hybridization. Although plasmacytomas are uncommon tumors of the head and neck, they may mimic other entities that require different treatment. Prompt and accurate diagnosis is critical for appropriate therapeutic decisions and prognosis.

RESUMEN

INTRODUCTION: The persistent lack of racial and ethnic diversity within the field of otolaryngology calls for an analysis of potential bias within the residency application system. Letters of recommendation (LORs) and personal statements (PSs) are the most important subjective application constituents. This subjectivity predisposes these components to implicit bias. In applications to various surgical subspecialties, prior linguistic studies assessing bias in reviews of LOR show race-based differences. Thus far, racial and ethnic linguistic differences in LORs for otolaryngology applicants have not been analyzed in the literature. METHODS: LORs and PSs were abstracted from otolaryngology - head and neck surgery applications in the Electronic Residency Application Service for the 2019-20 and 2020-21 application cycles. Linguistic Inquiry and Word Count 2015 was used for quantitative analysis of emotional, cognitive, and structural components of written text. RESULTS: Race-pair analysis of the 2019-2021 application cycles revealed higher mean "teaching" scores for LORs for Asian, black, Hispanic, and white applicants when compared to applicants who self-identified as Other. White applicants had lower scores for the terms "research" and "analytic" when compared to Asian and black applicants, respectively. Analysis of PSs revealed greater scores for an "authentic" writing style for white versus Asian applicants. White applicants were found to have higher scores for "tone" compared to black applicants. CONCLUSION: Minor racial and ethnic language differences exist in both LORs and PSs. A statistically significant difference was observed among LORs, with the "teaching" term used more frequently for Asian, black, Hispanic, and white applicants compared to self-identified Other individuals. For PSs, statistically significant differences were observed among white applicants, who wrote about themselves using more "authentic" language when compared with Asian applicants and who also had higher scores for "tone" compared to black applicants. Although these differences were statistically significant, the practical impact of the variances is likely small.

RESUMEN

INTRODUCTION: Over the last 3 years, the FDA has approved dupilumab, omalizumab, and mepolizumab for the treatment of CRSwNP; however, adverse events of these biologics have not been described in post-marketing surveillance trials. By utilizing the FDA Adverse Event Reporting System (FAERS), this study describes and compares biologic-associated adverse events in T2 disease. METHODS: This case-non-case study assessed disproportionate reporting rates using reporting odds ratios (RORs). RORs and p values for biologic-associated AEs were categorized and compared among dupilumab, omalizumab, and mepolizumab. This analysis included AEs associated with all treatment indications. Relative AE rates and outcomes were calculated. RESULTS: There were a total of 112,560, 24,428, and 18,741 unique AE reports associated with dupilumab, omalizumab, and mepolizumab, respectively. Omalizumab had the strongest association with anaphylaxis (ROR = 20.80, 95% confidence interval [CI]: 18.58, 23.29). Dupilumab had large relative proportions and positive signals in the ophthalmologic category (7.76%, ROR = 6.20, 95% CI: 6.06, 6.35), such as with blurry vision (ROR = 3.80, CI: 3.52, 4.12) and visual impairment (ROR = 1.98, CI: 1.80, 2.19). Dupilumab was the only biologic associated with injection-site reactions (7.98%, ROR = 8.17, 95% CI: 7.98, 8.37). DISCUSSION/CONCLUSION: This is the first large-scale comparative analysis of the AE profiles of dupilumab, omalizumab, and mepolizumab. Our data suggest possible relations between dupilumab and ophthalmologic and injection-site AEs. Omalizumab was the only biologic with a positive anaphylaxis signal. This FAERS investigation suggests important AE differences among these biologics.

RESUMEN

OBJECTIVE: This study aimed to evaluate the non-Food and Drug Administration-approved off-label use of a 10F Foley catheter as a tool during endoscopic frontal sinus surgery. METHOD: A cohort of 40 patients with chronic frontal rhinosinusitis was prospectively evaluated using the Sino-Nasal Outcome Test (SNOT-22), computed tomography (CT) imaging, and endoscopic examination. Endoscopic sinus surgery (ESS) was performed in the usual fashion, however, when approaching the frontal sinus, a 10F Foley catheter was inserted and the balloon inflated in the frontal outflow. Patients were assessed postoperatively with SNOT-22, CT imaging, and endoscopic assessment at 6 months. RESULTS: Successful intraoperative dilation of the frontal recess was achieved in 62 of 69 frontal sinuses (90%). No cerebrospinal fluid leak or orbital entry occurred. Six months postoperative, SNOT-22 scores showed significant improvement, whereas endoscopic assessment revealed patent frontal recess in 55 of 62 (89%) frontal sinuses. Computed tomography imaging was completed in 25 patients comprising 41 operated frontal sinuses with no mucosal thickening seen in 37 of 41 (90%). CONCLUSION: The 10F Foley catheter is an effective tool to dilate the frontal recess by compression of edema during ESS. It may be a safe and cost-effective alternative to high-cost commercially available sinus balloons, especially in resource-poor environments.

RESUMEN

BACKGROUND: Previous studies of endoscopic frontal sinus surgery have been primarily retrospective and focused on symptom relief only. OBJECTIVES: To prospectively assess the impact of endoscopic frontal sinus surgery on frontal sinus ostium patency and disease-specific quality of life as measured by the Rhinosinusitis Disability Index (RSDI). STUDY DESIGN: A 60-patient cohort with chronic frontal sinusitis (100 diseased frontal sinuses) was prospectively evaluated using the RSDI, computed tomography (CT) imaging, and endoscopic examination. Image-guided endoscopic frontal sinusotomy (Draf 2a) was performed in each case. Patients were assessed with RSDI and endoscopic assessment at least 6 months postoperatively. RESULTS: At a mean follow-up of 10 months, endoscopic assessment revealed patent frontal recesses in 90 of 100 frontal sinuses (90%), with significant improvement in the total RSDI score (41.98 ± 26.48 preoperatively to 17.15 ± 15.66 postoperatively) as well as each of its physical, emotional, and functional subscales from 16.3 ± 9.03, 12.23 ± 10.55, 13.45 ± 9.59 preoperatively to 5.95 ± 5.71, 5.55 ± 5.66, 5.65 ± 5.72 postoperatively, respectively. Similar improvement was seen in patients with asthma, polyps, and those undergoing revision sinus surgeries. CONCLUSIONS: With frontal recess mucosal preservation and meticulous postoperative endoscopic surveillance, endoscopic frontal sinusotomy results in high rates of frontal sinus ostium patency with significant improvement in quality of life.

RESUMEN

OBJECTIVE: To compare normal saline (NS) vs. NS+budesonide irrigations in post- functional endoscopic sinus surgery (FESS) patients with chronic rhinosinusitis with polyposis (CRSwNP). Currently, no evidence exists for NS+budesonide irrigation over NS irrigation alone. STUDY DESIGN: Prospective, single-blind, randomized controlled trial. METHODS: Subjects were prospectively enrolled to NS or NS+budesonide arms. Patients were evaluated at pre-operative and three post-operative visits (POV): POV1 (1-2 weeks post-op), POV2 (3-8 weeks post-op), and POV3 (3-6 months post-op). Patients were evaluated by three quality of life (QOL) questionnaires (SNOT-22, RSOM-31, and RSDI) and two olfaction scores (UPSIT and the PEA test). RESULTS: Fifty patients were randomized, with 25 patients in the NS arm and 25 patients in the NS+budesonide arm. Two patients had unexpected pathology and were excluded from the study. By POV2 and POV3, patients experienced a significant improvement in all three QOL surveys, although the degree of improvement between arms was not significant up through POV3. Neither arm experienced significant olfactory improvement up through POV3. CONCLUSIONS: While both NS and NS+budesonide treatments improve QOL for post-FESS patients, neither intervention significantly increases QOL as compared to the other. Olfaction was not significantly improved in either treatment group.

RESUMEN

BACKGROUND: Limited quality of life data exist for pediatric chronic rhinosinusitis (CRS) patients undergoing endoscopic sinus surgery (ESS). Further exploration of the following areas will enhance understanding and support clinical decision-making: baseline and post-ESS general and disease-specific quality of life, parent vs. child report, and correlation of nasal endoscopy to sinus CT scores. METHODOLOGY: A prospective cohort study evaluated CRS patients age 5-18 undergoing ESS. Surveys were completed at two timepoints: (1) pre-ESS and (2) 30-90 days post-ESS, with parents completing general (PedsQLTM) and CRS-specific (SNOT-16 and SN-5) quality of life surveys and children completing PedsQLTM and SNOT-16 surveys. Preoperative Lund-Kennedy nasal endoscopy and Lund-Mackay sinus CT scores were calculated. Where appropriate, outcomes were stratified by cystic fibrosis status. RESULTS: Impaired preoperative general quality of life was evidenced by parent proxy-report of PedsQLTM scores in 10 cystic fibrosis and 11 non-CF patients. ESS was associated with decreased sinus symptoms at 1-3 months postoperatively with SN-5 change scores of -1.85 and -2.2, in CF and non-CF patients, respectively. Parents reported worse CRS symptoms via higher preoperative SNOT-16 scores than their children did. Nasal endoscopy and sinus CT scores correlated with a Spearman correlation coefficient of 0.51. Scores not reaching statistical significance included CF-related CRS SNOT-16 change scores and PedsQLTM general quality of life change scores. CONCLUSION: In pediatric patients with CRS electing ESS, general quality of life is impaired preoperatively and sinus symptoms improve significantly 1-3 months after sinus surgery. Parents report statistically worse CRS symptom scores than their children do. Nasal endoscopy scores in this cohort correlated with sinus CT scores.

RESUMEN

A critical procedure in the transcribriform approach is the resection of the crista galli. However, the standard technique for crista galli resection has several disadvantages. We reviewed the cases of patients with olfactory neuroblastomas who underwent an endoscopic endonasal transcribriform approach using a newly developed technique for crista galli resection. We performed a cadaveric study to measure the superior accessibility limits using the proposed method. We included 38 patients with olfactory neuroblastomas in this study. The tumor invaded the posterior crista galli in four patients. The anterior end of the crista galli was not invaded by the tumor. Our cadaveric study showed that the dura was approachable to the point that was 7.4 ± 1.3 mm superior and 23.2 ± 7.2 mm lateral to the foramen cecum following crista galli removal. By resecting the crista galli in advance, manipulation of the superior dura became feasible.

RESUMEN

BACKGROUND: Intranasal corticosteroids (INCS) are a treatment mainstay of chronic rhinosinusitis and allergic rhinitis. Current computational models demonstrate that >90% of INCS drug deposition occurs on the head of the inferior turbinate and nasal valve, rather than the actual sinuses. These models do not consider mucociliary clearance which propels mucus posteriorly, nor do they consider the absorption of the drug. The purpose of this study is to better understand the exact anatomical location where INCS are absorbed. METHODS: Patients with chronic rhinosinusitis and allergic rhinitis taking fluticasone pre-operatively who were scheduled for functional endoscopic sinus surgery and inferior turbinate reduction, respectively, were recruited. Intra-operative tissue samples were obtained from predetermined locations within the sinonasal cavity. Mass spectrometry was then used to quantify the amount of absorption in each specific anatomic location to determine the largest amount of absorption. RESULTS: Eighteen patients were included in our study. The greatest fluticasone absorption levels across the sinonasal anatomy were at the anterior inferior turbinate (5.7 ngl/mL), ethmoid sinus, (4.4 ng/mL), posterior inferior turbinate (3.7 ng/mL), maxillary sinus (1.3 ng/mL), and the sphenoethmoidal recess (0.72 ng/mL) respectively. Absorption was significantly higher in revision surgery compared to surgically naïve patients. CONCLUSIONS: Computation fluid dynamic models of the nasal passage are useful models to help predict intranasal particle flow. However, these models do not incorporate or consider the important mucociliary clearance system, leading to absorption of fluticasone throughout the sinonasal cavity far beyond that predicted by these models.

RESUMEN

KEY POINTS: Automated plagiarism-checking software can be a valuable tool for detecting plagiarism in manuscripts. Twenty-five of 60 articles (42%) had at least one incidence of plagiarism, predominately text recycling. A "similarity score" ranging from 22% to 35% could be a potential cut-off value when screening submitted manuscripts.

RESUMEN

BACKGROUND: Priming is a psychological phenomenon where subconscious cues in the environment impact our behavioral responses in certain situations. Well studied in the worlds of business, marketing, and even politics, it is unclear how the priming phenomenon impacts patient perception of their own disease state nor how they report that perception using tools like the Sinonasal Outcomes Test (SNOT-22), used to measure that perception in chronic rhinosinusitis. OBJECTIVE: To determine the impact of positive or negative priming on self-reported patient perception of their chronic rhinosinusitis disease using the SNOT-22 disease-specific quality of life instrument. METHODS: Single-blind, randomized, prospective cohort pilot study of 206 consecutive adult patients with a clinical diagnosis of chronic rhinosinusitis presenting to a university rhinology clinic. Patients were randomized to receive "positive priming" (103) or "negative priming" (103) by reading a passage about the positive or negative aspects of chronic sinusitis and its treatment respectively. Patients were then asked to fill out the SNOT-22 and results between the two groups were compared. RESULTS: The negative priming group had a higher median SNOT-22 score of 49 [IQR = 39] compared to the positive priming groups' score of 22 [IQR = 27], p < 0.0001), a difference of nearly three times the minimal clinical impactful difference (MCID). This effect was consistent regardless of age or sex of the patient. Subgroup analysis revealed a greater impact when priming was performed by the senior male attending regardless of patient age or sex (p < 0.001), while priming performed by the younger female research fellow had greater impact on older patients (>59 years, p = 0.001) and female patients (p = 0.003). CONCLUSIONS: Priming impacts how patient's perceive their chronic rhinosinusitis as determined by the SNOT-22. It is imperative that the rhinologist understand this when using this instrument in research applications and in clinical decision-making for patients.

RESUMEN

Infratemporal fossa (ITF) tumors are rare in children and may present with a variety of symptoms. Teratomas are neoplasms derived from the 3 germ layers and approximately 6% to 10% are within the head and neck. Our study discusses one of the first reported cases of teratoma in the ITF in a pediatric patient. A 3-year-old girl presents with 2 years of recurrent monthly left periorbital swelling accompanied by fevers, skin discoloration, and pain. Prior episodes were treated with antibiotics with incomplete resolution. Imaging revealed a cystic lesion centered in the ITF. She was taken for endoscopic endonasal biopsy of the lesion and had no complications. Pathology revealed a mature teratoma composed primarily of pancreatic tissue. Providers should consider masses such as teratoma in the differential for ITF tumors and periorbital edema unresponsive to typical treatment.

RESUMEN

BACKGROUND: Cerebrospinal fluid (CSF) leaks are potentially life-threatening conditions that can be diagnosed by detection of ß(2)-transferrin using protein electrophoresis. Another less commonly available test is ß-trace protein quantitation using immunoassay. The objectives of this study were to evaluate a new immunofixation-based ß(2)-transferrin test for detection of CSF leaks and to compare it to an existing agarose gel electrophoresis test and ß-trace protein immunoassay. METHODS: For method comparison, 63 consecutive samples from physician-ordered ß(2)-transferrin tests were analyzed using two different electrophoresis methods, agarose gel fractionation followed by acid-violet staining, and high resolution agarose gel electrophoresis followed by ß(2)-transferrin immunofixation. A subset of samples (16/63) were analyzed for ß-trace protein. Results were compared against patient chart data for the presence of a CSF leak. Additional studies were performed to assess the stability, detection limit, and analytical specificity of the ß(2)-transferrin immunofixation test. RESULTS: The ß(2)-transferrin immunofixation test had a sensitivity of 100 % (40/40) and specificity of 71 % (12/17) for detection of CSF leaks. By comparison, the agarose gel test had a sensitivity of 87 % (35/40) and specificity of 94 % (16/17). ß-trace protein had a sensitivity of 100 % (10/10) and specificity of 86 % (5/6). Serum and saliva could be differentiated from CSF by the ß(2)-transferrin immunofixation test based on their migration patterns. However, whole blood samples appeared positive for ß(2)-transferrin at a threshold of ~ 4 g/L hemoglobin. At a cut-off of 3 mg/L, ß-trace protein was increased in 10/10 cases with documented CSF leak and in 1/6 patients without CSF leak. CONCLUSIONS: Both the new immunofixation test for ß(2)-transferrin and the ß-trace protein were effective at detecting CSF leaks. Users of the ß(2)-transferrin immunofixation test should be cautioned against interpreting samples with blood contamination.

RESUMEN

OBJECTIVE: To compare the usefulness of 3 currently used classification systems in predicting the outcomes of treatment resistance, disease relapse, end-stage renal disease (ESRD), and death in patients with antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV). METHODS: Three classification systems were applied to 502 patients with biopsy-proven AAV: 1) the Chapel Hill Consensus Conference (CHCC) definition with categories for granulomatosis with polyangiitis (GPA) (Wegener's), microscopic polyangiitis (MPA), and kidney-limited disease; 2) the European Medicines Agency (EMA) system with categories for GPA and MPA; and 3) classification based on ANCA with specificity for myeloperoxidase (MPO ANCA) versus ANCA with specificity for proteinase 3 (PR3 ANCA). Outcomes included treatment resistance, relapse, ESRD, and death. Proportional hazards models were compared between systems using an information-theoretic approach to rank models by predictive fit. Hazard ratios (HRs) with 95% confidence intervals (95% CIs) and P values are reported. RESULTS: ANCA specificity was predictive of relapse, with PR3 ANCA-positive patients almost twice as likely to relapse as those with MPO ANCA (HR 1.89 [95% CI 1.33-2.69], P = 0.0004), and ANCA specificity had the best predictive model fit (model rank 1) compared to the CHCC and EMA systems. The CHCC and EMA systems did not predict relapse. By ANCA specificity, categories of GPA, MPA, and kidney-limited disease did not distinguish differences in probability of relapse-free survival. None of the systems predicted treatment resistance, ESRD, or death. CONCLUSION: ANCA specificity independently predicts relapse among patients with AAV with renal disease. Classification and diagnostic systems that incorporate ANCA specificity, such as PR3 ANCA-positive MPA and MPO ANCA-positive MPA, provide a more useful tool than the clinical pathologic category alone for predicting relapse.

RESUMEN

Dupilumab and other biologics have revolutionized the management of recalcitrant polyps in patients with chronic rhinosinusitis with nasal polyposis (CRSwNP). Despite strong evidence for the efficacy of dupilumab in treating polyps, factors such as cost and uncertain efficacy over surgery have limited its use to patients who have failed the use of topical nasal steroids and initial surgical management. Likewise, the use of this drug is often directed towards patients with greater polyp burdens. Recent studies, however, have investigated the use of dupilumab and other biologics in expanded patient populations, including those with limited polyp burden. The overall trend in the literature suggests a future move towards the use of biologics as first-line therapy for all patients with CRSwNP. The arguments against widespread, routine use of dupilumab and biologics in all patients with CRSwNP are threefold. First, endoscopic sinus surgery has been found to provide similar symptomatic benefit to dupilumab in the treatment of these patient populations. The surgical improvement of patients' sinonasal anatomy offers a rapid elimination of sources of ongoing inflammation that contribute to long-term polyp formation and symptoms. Medical non-compliance in this specific patient population is known to be an issue, with surgery offering a much greater long-term prospect of symptomatic relief in non-compliant patients. The second concern revolves around the potential for side effects of dupilumab and other biologics. Initial studies have shown an acceptable safety profile, but trials assessing the use of dupilumab for a separate indication revealed a higher rate of conjunctivitis. Long-term safety data is limited for biologics, and we must be prepared for the possibility of severe, unanticipated adverse events in the future. Our third and most profound concern is the significant cost of dupilumab. This medication is enormously expensive, and all current literature suggests that treatment would need to be life-long to remain effective. Studies comparing endoscopic sinus surgery to various biologics, including dupilumab, have shown comparable overall quality of life metrics with biologics, all while delivering considerably higher anticipated lifetime costs. As our knowledge progresses regarding the efficacy of dupilumab and other biologics in a variety of clinic situations, it is important to understand the context in which these advances are being made. While dupilumab and other biologics offer undeniable efficacy in the treatment of chronic rhinosinusitis with nasal polyposis which has failed to respond to standard therapies, we argue that biologics remain only a component of effective management in this patient population. Endoscopic sinus surgery and topical nasal steroids offer equal efficacy and substantially lower costs than biologics, and these factors should be considered when selecting treatment options for patients.

RESUMEN

Background: The emergence of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) has resulted in an unprecedented global pandemic. Most infected patients are either asymptomatic or have mild upper respiratory infection symptoms. However, life-threatening sequelae have been observed. In this report, we reviewed nine cases of patients with severe complications from sinonasal disease in the setting of acute SARS-CoV-2 infection. Methods: IRB approval was obtained prior to study initiation. A retrospective chart review was performed of patients admitted to a tertiary hospital with complex sinonasal symptoms that required otolaryngologic evaluation and management in the setting of concomitant SARS-CoV-2 infection. Results: Nine patients, ranging from ages 3 to 71 years, with sinonasal disease and simultaneous SARS-CoV-2 infection were identified. Initial presentations ranged from asymptomatic infection to mild/moderate disease (nasal obstruction, cough) or more severe sequelae including epistaxis, proptosis, or neurologic changes. SARS-CoV-2 tests were positive from one to 12 days after symptom onset, with three patients receiving SARS-CoV-2-directed treatment. Complex disease presentations included bilateral orbital abscesses, suppurative intracranial infection, cavernous sinus thrombosis with epidural abscess, systemic hematogenous spread with abscess development in four distinct anatomic locations, and hemorrhagic benign adenoidal tissue. Eight of nine patients (88.8%) required operative intervention. Patients with abscesses also required prolonged, culture-directed antibiotic courses. Conclusion: Though most SARS-CoV-2 infections are asymptomatic and/or self-limited, there is significant morbidity and mortality in patients with severe disease sequela as outlined in our reported cases. This suggests early identification and treatment of sinonasal disease in this patient population is critical to minimizing poor outcomes. Further research on the pathophysiology of these atypical presentations is needed. Level of Evidence: 4 (Case Series).
