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.
...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.
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.
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.
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.
Background
Organ preservation protocols have increasingly been applied for the treatment of head and neck cancers, including hypopharyngeal squamous cell carcinoma (HSCC). We sought to evaluate ...whether patients treated with primary surgery followed by adjuvant therapy had survival benefit over patients treated with initial nonsurgical modalities.
Methods
We retrospectively reviewed patients with new diagnosis of HSCC at the University of Pittsburgh (1994‐2014) treated with either primary total laryngectomy with pharyngectomy or organ preservation.
Results
One hundred thirty‐seven patients were identified. Surgical cases were more likely to be of advanced T stage. Initial surgery was more likely to be performed in the earlier years of the cohort. After adjusting for this imbalance using a propensity score, primary surgery was associated with improved survival compared with nonoperative therapy (P = 0.02).
Conclusions
Due to its survival advantage, primary surgery followed by adjuvant treatment should be considered as a viable treatment of HSCC.
Poorly differentiated thyroid cancer and anaplastic thyroid cancer (ATC) are rare yet lethal malignancies with limited treatment options. Many malignant tumors, including papillary thyroid cancer ...(PTC) and ATC, are associated with increased expression of ICAM-1, providing a rationale for utilizing ICAM-1-targeting agents for the treatment of aggressive cancer. We developed a third-generation chimeric antigen receptor (CAR) targeting ICAM-1 to leverage adoptive T-cell therapy as a new treatment modality.
ICAM-1 CAR T cells were applied to multiple malignant and nonmalignant target cells to investigate specific target cell death and "off-tumor" toxicity
therapeutic efficacy of ICAM-1 CAR T cells was examined in ATC mouse models established from a cell line and patient-derived tumors that rapidly develop systemic metastases.
ICAM-1 CAR T cells demonstrated robust and specific killing of PTC and ATC cell lines
Interestingly, although certain ATC cell lines showed heterogeneous levels of ICAM-1 expression, addition of cytotoxic CAR T cells induced increased ICAM-1 expression such that all cell lines became targetable. In mice with systemic ATC, a single administration of ICAM-1 CAR T cells mediated profound tumor killing that resulted in long-term remission and significantly improved survival. Patient-derived ATC cells overexpressed ICAM-1 and were largely eliminated by autologous ICAM-1 CAR T cells
and in animal models.
Our findings are the first demonstration of CAR T therapy against both a metastatic, thyroid cancer cell line and advanced ATC patient-derived tumors that exhibit dramatic therapeutic efficacy and survival benefit in animal studies.

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.

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.
Objectives/Hypothesis
Previous studies report high‐accuracy rates for intraoperative frozen sections, but reliability of frozen sections in predicting the ultimate final margin status is unknown. We ...compared frozen and permanent reads to identify risk factors for overall discrepancies between intraoperative and final margin status.
Study Design
Retrospective chart review.
Methods
Pathology reports of 437 surgical resections between 2010 and 2013 were retrospectively reviewed. A total of 253 cases, generating 1,109 individual specimens, met inclusion criteria. Patient demographics, treatment, recurrence, and survival, as well as pathology data pertaining to the specimen, were recorded.
Results
Frozen read accuracy was 96.7% (83.1% sensitivity, 97.9% specificity) relative to permanent evaluation. However, 4.3% of cases had a final positive margin not detected by frozen section; 17.8% had a close margin not detected by frozen section. In eight of 11 cases with missed positive margins, the involved margin was never sampled intraoperatively. Cases where intraoperative margins were only taken from surrounding tissue had a higher risk of missing a close or positive final margin when compared to cases where some or all margins were taken from the specimen (odds ratio = 5.05, 95% confidence interval 2.31, 11.07, P <0.0001). Disease subsite, risk score, prior radiation, staging, and p16 expression were not significantly associated with the likelihood of missing a close or positive final margin.
Conclusion
Individual frozen section reads are highly accurate. However, negative intraoperative margins do not guarantee margin‐negative resections. The process of selecting representative margins for intraoperative analysis, specifically the practice of sampling the resection bed, should be refined.

Summary
Computed tomography (CT)-guided percutaneous biopsy of deep-seated head and neck lesions can be a less invasive and equally effective alternative to surgical techniques. There are multiple ...approaches for needle biopsy that target varying spaces within the head and neck while successfully avoiding critical anatomy. In the paramaxillary approach, the needle is advanced through the infrazygomatic buccal space, in between the maxilla and mandible. In this study, we examine the safety and diagnostic yield of FNA without core needle biopsy performed via the paramaxillary approach in 19 patients yielding 20 fine needle aspirates between 2014 and 2022. Of the fine needle aspirates, 85.0% (17/20) were diagnostic. Concordant histopathologic diagnosis was obtained in 100% (17/17) diagnostic fine needle aspirates. There were no postprocedural complications.
Context:
Calcitonin is a sensitive biomarker that is used for diagnosis and follow-up in medullary thyroid cancer (MTC). In patients with tumors > 1 cm, it is uncommon for preoperative serum ...calcitonin to be in the normal laboratory reference range in patients with MTC, and even more unusual for serum calcitonin to be undetectable.
The Case:
A 39-year-old woman was found to have a left thyroid nodule on magnetic resonance imaging done for neck pain. Ultrasound and fine-needle aspiration biopsy were performed, and cytopathology was positive for malignant cells. The cells also had features suggestive of a neuroendocrine tumor, and the specimen was immune-stained with calcitonin. There was positive immunoreactivity for calcitonin in isolated cells of the cytospin, highly favoring a diagnosis of MTC. Serum calcitonin was < 2 pg/mL (<6 pg/mL), and serum carcinoembryonic antigen was 3.1 ng/mL (<5.2 ng/mL). Given the low calcitonin levels, procalcitonin was also tested and was elevated at 0.21 ng/mL (< 0.1 ng/mL). The patient subsequently underwent a total thyroidectomy and central and ipsilateral lateral lymph node dissection. Histopathology confirmed a 2.6 × 2.0 × 1.2-cm MTC, with strong, diffuse immunostaining for calcitonin. Postoperatively, serum calcitonin has remained undetectable, carcinoembryonic antigen has remained within the reference range, and procalcitonin has become undetectable.
Conclusions:
We present a rare case of a patient with MTC with undetectable preoperative serum calcitonin, whose tumor demonstrated strong, diffuse immunohistochemical staining for calcitonin. We discuss the possible pathogenesis of calcitonin-negative MTC and the challenges in following patients with this condition.
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.
