Intranasal Trigeminal Function in Aging Adults.

BACKGROUND: Intranasal trigeminal function is important in detecting environmental stimuli. The impact of age-associated chemosensory dysfunction upon taste and olfaction is well described, but an understanding of trigeminal loss (chemesthesis) is lacking. OBJECTIVE: The goal of this study was to characterize trigeminal function in a cohort of older adults and explore potential impacts. METHODS: Twenty-eight participants over 50 years of age were recruited from the community as part of an aging cohort study. This nested cohort completed chemosensory questionnaires, patient-reported outcome measures (PROMs), and psychophysical testing for taste (taste strips), olfaction (Sniffin' Sticks), and trigeminal function (eucalyptol lateralization). Data were analyzed for associations between trigeminal function, olfactory, and taste psychophysical performance, patient-reported metrics, and demographic risk factors. RESULTS: Patient-reported trigeminal impairment is less severe than other chemosensory loss, with mean visual analog scores (VAS, rated 0-100 from least to most severe) for smell (32.9 ± 34.2), taste (20.6 ± 28.4), and trigeminal sensation (9.5 ± 12.8). Despite low VAS scores, psychophysical trigeminal dysfunction was present in 10 (35.7%) subjects. Psychophysical olfactory and taste dysfunction were present in 16 (57.1%) and eight (28.6%) participants respectively. Hypercholesterolemia was associated with psychophysical trigeminal dysfunction (mean lateralization performance in hypercholesterolemia 57.7% ± 17.1 vs. 74.1% ± 10.4, p = .008). CONCLUSION: Intranasal trigeminal impairment is present in nearly one-third of aging adults when assessed by psychophysical methods but is under-recognized. Hyperlipidemia may be associated with trigeminal impairment. Future inquiries should better characterize these findings in larger and prospective cohorts.

Use of Intraoperative Frozen Section to Assess Final Tumor Margin Status in Patients Undergoing Surgery for Oral Cavity Squamous Cell Carcinoma.

Importance: Methods of assessing final margin status in patients undergoing surgery for oral cavity squamous cell carcinoma, such as intraoperative frozen section histopathology (IFSH) taken from the tumor bed, may have limitations in accuracy. Objective: To evaluate the accuracy and implications of using IFSH samples to assess tumor bed margins in patients undergoing surgery for oral cavity squamous cell carcinoma (SCC). Design, Setting, and Participants: This cross-sectional study included 1257 patients who underwent surgery for oral cavity SCC between January 1, 2000, and December 31, 2015, at an academic cancer center. A total of 4821 IFSH samples were examined from 1104 patients (87.8%) who had at least 1 IFSH sample. Institutional practice is to harvest margins for IFSH from the tumor bed. Statistical analysis was performed from August 1, 2021, to April 4, 2022. Main Outcomes and Measures: Sensitivity and specificity were calculated for IFSH samples of margins compared with the permanent pathology samples of the same tissue and for IFSH compared with the final tumor specimen histopathology (FTSH). Results were classified using a binary method, with histopathologic reports interpreted as either negative (including negative or atypia or dysplasia) or positive (including carcinoma in situ, suspicious, or positive). Results: A total of 1257 patients met the inclusion criteria, including 709 men (56.4%), with a median age of 62 years (IQR, 52-73 years); 1104 patients (627 men [56.8%]; median age, 62 years [IQR, 52-72 years]) had IFHS samples. For IFSH relative to permanent sections of the IFSH tissue, sensitivity and specificity of IFSH were high (sensitivity, 76.5% [95% CI, 67.5%-85.5%]; specificity, 99.9% [95% CI, 99.8%-100%]), with discordant results in 24 of 4821 total specimens (0.5%). Final specimen margins were positive in 11.7% of patients (147 of 1257). Compared with FTSH, the sensitivity of IFSH for defining margin status was 10.8% (95% CI, 5.8%-15.8%), and the specificity was 99.1% (95% CI, 98.8%-99.4%). The rate of discordance was 4.0% (171 of 4284 specimens) between IFSH and FTSH. Conclusions and Relevance: The findings of this cross-sectional study suggest that IFSH is accurate compared with permanent pathologic characteristics of the same tissue, but less reliable at assessing final margin status on the tumor specimen. Despite a high specificity, the sensitivity of IFSH compared with FTSH is low, which may be associated with the inherent inability of tumor bed IFSH margin analysis to accurately account for the 3-dimensional association of tumor margins with the periphery of the specimen and the overall low rate of positive final tumor margins. Although tumor bed IFSH is widely used in the management of oral cavity cancer, this study suggests that there are limitations of this modality in assessing the final surgical margin status.

Temporal Dynamics of Nasopharyngeal and Tracheal Severe Acute Respiratory Syndrome Coronavirus 2 Cycle Thresholds in Coronavirus Disease 2019 Patients With Tracheostomy.

In this study of 45 patients with COVID-19 undergoing tracheostomy, nasopharyngeal and tracheal cycle threshold (Ct) values were analyzed. Ct values rose to 37.9 by the time of tracheostomy and remained >35 postoperatively, demonstrating that persistent test positivity may not be associated with persistent transmissible virus in this population.

Healthcare Disparities in Laryngology: A Scoping Review.

OBJECTIVES/HYPOTHESIS: This scoping review aims to map out existing disparities research within the subspecialty of laryngology in order to highlight gaps in knowledge and guide future research. STUDY DESIGN: Scoping Review. METHODS: We completed a scoping review of PubMed, Ovid Embase, and the Cochrane Library for primary research focused on evaluating the existence and impact of disparities in race/ethnicity, sex/gender, insurance status, education level, income, geography, and LGBTQ identity in the context of various laryngological conditions. Publications of any design and date, performed in the United States, and focusing on the adult population exclusively were included. RESULTS: Of the 4,999 unique abstracts identified, 51 articles were ultimately included. The most frequently examined condition in relation to disparities was laryngeal cancer (27 of 51), followed by voice disorders (15 of 51), deglutitive disorders (eight of 51), and airway disorders (one of 51). Sources of inequity evaluated from most common to least common were race/ethnicity (43 of 51), sex/gender (39 of 51), insurance status (23 of 51), geography (23 of 51), income (21 of 51), and education level (16 of 51). No study examined the association of LGBTQ identity with inequity. CONCLUSIONS: This scoping review highlights the limited extent of disparities research in laryngology and establishes the need for further scholarship on the impact of disparities in laryngology care. The pathologies studied were, in decreasing order of frequency: laryngeal cancer, voice disorders, deglutitive disorders, and airway disorders. Race/ethnicity and sex/gender were the most common disparities examined, with no evaluation of LGBTQ-related care inequity. LEVEL OF EVIDENCE: NA Laryngoscope, 132:375-390, 2022.

Essential inpatient otolaryngology: what COVID-19 has revealed.

PURPOSE: To identify areas of critical otolaryngology contributions to inpatient care resistant to disruption by the COVID-19 pandemic. METHODS: Medical records of 614 otolaryngology consults seen between January and June of 2019 and 602 seen between January and June of 2020 were reviewed. Extracted data included patient demographics, SARS-CoV-2 status, medical comorbidities, consult location, consult category, reason for consult, procedures performed, and overall outcome. Prevalence of data items was compared using t tests and Chi-squared tests. RESULTS: The number of monthly consults to the otolaryngology service remained approximately stable after the onset of the COVID-19 pandemic. However, there was a substantial increase in ICU consults and a decrease in ER and floor consults. The proportion of otology, rhinology, and head and neck consults decreased while that of airway consults-most of which were tracheostomy-related-greatly increased. While the top ten reasons for consult remained essentially the same, they dramatically increased as a percentage of consults during COVID-19 (55-92%), whereas there was a dramatic decrease in the proportion of less frequent consults. CONCLUSION: The changes in otolaryngology consultation patterns seen after the onset of the pandemic are multifactorial, but may be attributed to novel pathologies, attitudes, and policies. Nonetheless, these patterns reveal that a set of core otolaryngologic issues, including acute airway issues, head and neck lesions, severe sinusitis and epistaxis, are essential and need to be addressed in the inpatient setting, whereas the significant drop in other consults suggests that they may be appropriately managed on an outpatient basis.

Massive vagal schwannoma in an 11-year-old girl.

We describe an unusual case of a young girl presenting with a large vagal schwannoma necessitating a transcervical-mandibulotomy approach for total tumor resection. The presentation is unique due to the size of the lesion, the patient's age, the operative approach, and molecular pathology.

Percutaneous and Open Tracheostomy in Patients With COVID-19: The Weill Cornell Experience in New York City.

OBJECTIVE: Report long-term tracheostomy outcomes in patients with COVID-19. STUDY DESIGN: Review of prospectively collected data. METHODS: Prospectively collected data were extracted for adults with COVID-19 undergoing percutaneous or open tracheostomy between April 4, 2020 and June 2, 2020 at a major medical center in New York City. The primary endpoint was weaning from mechanical ventilation. Secondary outcomes included sedation weaning, decannulation, and discharge. RESULTS: One hundred one patients underwent tracheostomy, including 48 percutaneous (48%) and 53 open (52%), after a median intubation time of 24 days (IQR 20, 31). The most common complication was minor bleeding (n = 18, 18%). The all-cause mortality rate was 15% and no deaths were attributable to the tracheostomy. Eighty-three patients (82%) were weaned off mechanical ventilation, 88 patients (87%) were weaned off sedation, and 72 patients (71%) were decannulated. Censored median times from tracheostomy to sedation and ventilator weaning were 8 (95% CI 6-11) and 18 (95% CI 14-22) days, respectively (uncensored: 7 and 15 days). Median time from tracheostomy to decannulation was 36 (95% CI 32-47) days (uncensored: 32 days). Of those decannulated, 82% were decannulated during their index admission. There were no differences in outcomes or complication rates between percutaneous and open tracheostomy. Likelihood of discharge from the ICU was inversely related to intubation time, though the clinical relevance of this was small (HR 0.97, 95% CI 0.943-0.998; P = .037). CONCLUSION: Tracheostomy by either percutaneous or open technique facilitated sedation and ventilator weaning in patients with COVID-19 after prolonged intubation. Additional study on the optimal timing of tracheostomy in patients with COVID-19 is warranted. LEVEL OF EVIDENCE: 3 Laryngoscope, 131:E2849-E2856, 2021.

Percutaneous and Open Tracheostomy in Patients with COVID-19: Comparison and Outcomes of an Institutional Series in New York City.

OBJECTIVE: The aim of this study was to report the safety, efficacy, and early results of tracheostomy in patients with COVID-19 and determine whether differences exist between percutaneous and open methods. SUMMARY BACKGROUND DATA: Prolonged respiratory failure is common in symptomatic patients with COVID-19, the disease process caused by infection with the novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Tracheostomy, although posing potential risk to the operative team and other healthcare workers, may be beneficial for safe weaning of sedation and ventilator support. However, short- and long-term outcomes remain largely unknown. METHODS: A prospectively collected database of patients with COVID-19 undergoing tracheostomy at a major medical center in New York City between April 4 and April 30, 2020 was reviewed. The primary endpoint was need for continued mechanical ventilation. Secondary outcomes included complication rates, sedation weaning, and need for intensive care unit (ICU) level of care. Patient characteristics, perioperative conditions, and outcomes between percutaneous and open groups were analyzed. RESULTS: During the study period, 67 consecutive patients underwent tracheostomy, including 48 males and 19 females with a median age of 66 years [interquartile range (IQR) 52-72]. Two surgeons alternated techniques, with 35 tracheostomies performed percutaneously and 32 via an open approach. The median time from intubation to tracheostomy was 23 days (IQR 20-26). At a median follow-up of 26 days, 52 patients (78%) no longer required mechanical ventilation and 58 patients (87%) were off continuous sedation. Five patients (7.5%) died of systemic causes. There were 11 total complications (16%) in 10 patients, most of which involved minor bleeding. There were no significant differences in outcomes between percutaneous and open methods. CONCLUSIONS: Tracheostomy under apneic conditions by either percutaneous or open technique can be safely performed in patients with respiratory failure due to COVID-19. Tracheostomy facilitated weaning from continuous intravenous sedation and mechanical ventilation. Continued follow-up of these patients to ascertain long-term outcome data is ongoing.

Surgical ovarian suppression for adjuvant treatment in hormone receptor positive breast cancer in premenopausal patients.

OBJECTIVE: Ovarian suppression is recommended to complement endocrine therapy in premenopausal women with breast cancer and high-risk features. It can be achieved by either medical ovarian suppression or therapeutic bilateral salpingo-oophorectomy. Our objective was to evaluate characteristics of patients with stage I-III hormone receptor positive primary breast cancer who underwent bilateral salpingo-oophorectomy at our institution. MATERIALS AND METHODS: Premenopausal women with stage I-III hormone receptor positive primary breast cancer diagnosed between January 2010 and December 2014 were identified from a database. Patients with confirmed BRCA1/2 mutations were excluded. Distribution of characteristics between treatment groups was assessed using χ2 test and univariate logistic regression. A multivariate model was based on factors significant on univariate analysis. RESULTS: Of 2740 women identified, 2018 (74%) received endocrine treatment without ovarian ablation, 516 (19%) received endocrine treatment plus ovarian ablation, and 206 (7.5%) did not receive endocrine treatment. Among patients undergoing ovarian ablation 282/516 (55%) received medical ovarian suppression, while 234 (45%) underwent bilateral salpingo-oophorectomy. By univariate logistic analyses, predictors for ovarian ablation were younger age (OR 0.97), histology (other vs ductal: OR 0.23), lymph node involvement (OR 1.89), higher International Federation of Gynecology and Obstetrics (FIGO) stage (stage II vs I: OR 1.48; stage III vs I: OR 2.86), higher grade (grade 3 vs 1: OR 3.41; grade 2 vs 1: OR 2.99), chemotherapy (OR 1.52), and more recent year of diagnosis (2014 vs 2010; OR 1.713). Only year of diagnosis, stage, and human epidermal growth factor receptor 2 (HER-2) treatment remained significant in the multivariate model. Within the cohort undergoing ovarian ablation, older age (OR 1.05) was associated with therapeutic bilateral salpingo-oophorectomy. Of 234 undergoing bilateral salpingo-oophorectomy, 12 (5%) mild to moderate adverse surgical events were recorded. CONCLUSIONS: Bilateral salpingo-oophorectomy is used frequently as an endocrine ablation strategy. Older age was associated with bilateral salpingo-oophorectomy. Perioperative morbidity was acceptable. Evaluation of long-term effects and quality of life associated with endocrine ablation will help guide patient/provider decision-making.

Pseudo-cobra neck deformity due to aplasia cutis congenita.

Aplasia cutis congenita is a rare but heterogeneous group of conditions characterized by the absence of one or more areas of skin sometimes extending to deeper tissues. The disorder as a solitary neck lesion has yet to be reported in the literature. Our patient presented with a pseudo-cobra neck deformity secondary to aplasia cutis congenita. Guidance on optimal management for non-scalp and more "benign" presentations of this disorder is lacking.

BRCA Mutations, Homologous DNA Repair Deficiency, Tumor Mutational Burden, and Response to Immune Checkpoint Inhibition in Recurrent Ovarian Cancer.

PURPOSE: Homologous DNA repair-deficient (HRD) ovarian cancers (OCs), including those with BRCA1/2 mutations, have higher levels of genetic instability, potentially resulting in higher immunogenicity, and have been suggested to respond better to immune checkpoint inhibitors (ICIs) than homologous DNA repair-proficient OCs. However, clinical evidence is lacking. The study aimed to evaluate the associations between BRCA1/2 mutations, HRD, and other genomic parameters and response to ICIs and survival in OC. METHODS: This is a single-institution retrospective analysis of women with recurrent OC treated with ICIs. BRCA1/2 mutation status and clinicopathologic variables were abstracted from the medical records. Targeted and whole-exome sequencing data available for a subset of patients were used to assess tumor mutational burden (TMB), HRD, and fraction of genome altered (FGA). ICI response was defined as lack of disease progression for ≥ 24 weeks. Associations of BRCA1/2 status and genomic alterations with progression-free survival (PFS) and overall survival (OS) were determined using Cox proportional hazards models. RESULTS: Of the 143 women treated with ICIs, 134 had known BRCA1/2 mutation status. Deleterious germline or somatic BRCA1/2 mutations were present in 31 women (24%). There was no association between presence of BRCA1/2 mutations and response (P = .796) or survival. Genomic analysis in 73 women found no association between TMB (P = .344) or HRD (P = .222) and response, PFS, or OS. There were also no significant differences in somatic genetic alterations between responders and nonresponders. High FGA was associated with an improvement in PFS (P = .014) and OS (P = .01). CONCLUSION: TMB, BRCA1/2 mutations, and HRD are not associated with response or survival, cautioning against their use as selection criteria for ICI in recurrent OC. FGA should be investigated further as a biomarker of response to immunotherapy in OC.

Clinical patterns and genomic profiling of recurrent 'ultra-low risk' endometrial cancer.

OBJECTIVE: Despite good prognosis for patients with low-risk endometrial cancer, a small subset of women with low-grade/low-stage endometrial cancer experience disease recurrence and death. The aim of this study was to characterize clinical features and mutational profiles of recurrent, low-grade, non-myoinvasive, 'ultra-low risk' endometrioid endometrial adenocarcinomas. METHODS: We retrospectively identified patients with International Federation of Gynecology and Obstetrics (FIGO) stage IA endometrioid endometrial cancers who underwent primary surgery at our institution, between January 2009 and February 2017, with follow-up of ≥12 months. 'Ultra-low risk' was defined as FIGO tumor grade 1, non-myoinvasive, and lacking lymphovascular space invasion. Tumor-normal profiling using massively parallel sequencing targeting 468 genes was performed. Microsatellite instability was assessed using MSIsensor. DNA mismatch repair (MMR) protein proficiency was determined by immunohistochemistry. RESULTS: A total of 486 patients with ultra-low risk endometrioid endometrial cancers were identified: 14 (2.9%) of 486 patients developed a recurrence. Median follow-up for non-recurrent endometrioid endometrial cancers: 34 (range 12-116) months; for recurrent endometrioid endometrial cancers: 50.5 (range 20-116) months. Patients with recurrent disease were older, had lower body mass index, and were most commonly non-White (p=0.025, p<0.001, and p<0.001, respectively). Other clinical characteristics did not differ. MMR immunohistochemistry was obtained for 211 (43%) tumors: 158 (75%) MMR-proficient and 53 (25%) MMR-deficient. Primary tumors of 9 recurrent and 27 non-recurrent endometrioid endometrial cancers underwent mutational profiling. Most were microsatellite stable (6/9, 67% recurrent; 25/27, 93% non-recurrent). Recurrent PTEN and PIK3CA mutations were present in both groups. Exon 3 CTNNB1 hotspot mutations were found in 4/9 (44%) recurrent and 8/27 (30%) non-recurrent (p=0.44). CONCLUSIONS: Patients diagnosed with ultra-low risk endometrioid endometrial cancers have an overall excellent prognosis. However, in our study, 2.9% of patients with no identifiable clinical or pathologic risk factors developed recurrence. Further work is warranted to elucidate the mechanism for recurrence in this population.

Brain metastasis in epithelial ovarian cancer by BRCA1/2 mutation status.

OBJECTIVE: To evaluate clinical outcomes of patients with BRCA-associated ovarian cancer who developed brain metastases (BM). METHODS: Patients with epithelial ovarian, fallopian tube, and primary peritoneal cancer (EOC) and BM, treated at a single institution from 1/1/2008-7/1/2018, were identified from two institutional databases. Charts and medical records were retrospectively reviewed for clinical characteristics and germline BRCA mutation status. Appropriate statistics were used. RESULTS: Of 3649 patients with EOC, 91 had BM (2.5%). Germline mutation status was available for 63 (69%) cases; 21 (35%) of these harbored a BRCA1/2 mutation (15 BRCA1, 6 BRCA2). Clinical characteristics were similar between groups. BM were diagnosed at a median of 31 months (95% CI, 22.6-39.4) in BRCA-mutated (mBRCA) and 32 months (95% CI, 23.7-40.3) in wild-type BRCA (wtBRCA) (p = 0.78) patients. Brain metastases were the only evidence of disease at time of BM diagnoses in 48% (n = 10) mBRCA and 19% (n = 8) wtBRCA (p = 0.02) patients. There was no difference in treatment of BM by mutation status (p = 0.84). Survival from time of BM diagnosis was 29 months (95%CI, 15.5-42.5) in mBRCA and 9 months (95% CI, 5.5-12.5) in wtBRCA patients, with an adjusted hazard ratio (HR) of 0.53, p = 0.09; 95% CI, 0.25-1.11. HR was adjusted for presence of systemic disease at time of BM diagnosis. CONCLUSION: This is the largest study to date comparing outcomes in patients with EOC and BM by mutation status. mBRCA patients were more likely to have isolated BM, which may be a factor in their long survival. This supports the pursuit of aggressive treatment for mBRCA EOC patients with BM. Additional studies examining the correlation of BRCA mutational status with BM are warranted.

Gastrointestinal metastasis of primary lung cancer: An analysis of 366 cases.

The gastrointestinal (GI) tract is not a common site of metastasis in primary lung cancer. The aim of the present study was to reveal the clinical and prognostic characteristics of gastrointestinal metastases of lung cancer (GMLC). Information on 366 cases of GMLC was collected and factors that affect severe GI complications were analyzed. Univariate and multivariate survival analyses were performed using the Cox proportional hazards model. Of the cases analyzed, the small intestine (59.6%) and colorectum (25.6%) were the two organs where lung cancer was most likely to metastasize in the GI tract. Squamous cell carcinoma (28.5%), adenocarcinoma (27.6%) and large cell carcinoma (20.9%) were the three most common histological types. However, compared with the histological distributions of primary lung cancer, patients with large cell carcinoma exhibited the highest elevated risk of GMLC [relative risk (RR), 4.07; P<0.001] and those with adenocarcinoma exhibited the lowest risk (RR, 0.58; P<0.001). Differences in organ involvement and in histological type led to varying GI complications. It was also indicated that chemotherapy was associated with a decreased risk of hemorrhage (P=0.006), but there was no reduction in the risk of hemorrhage associated with perforation and obstruction (P>0.05). The median overall survival time of GMLC patients was 2.8 months (range, 0-108 months). The survival analyses revealed that perforation and extra-GI metastasis were negative prognostic factors but abdominal surgery was identified a positive prognostic factor. In conclusion, the histological distribution of GMLC differed from that of primary lung cancer. Sufficient and careful patient evaluation, targeted surgeries and systemic therapies for specific patients are able to increase patient survival rate and improve the quality of life.
