Centralized Otolaryngology Research Efforts: Stepping‐stones to Innovation and Equity in Otolaryngology–Head and Neck Surgery

The Centralized Otolaryngology Research Efforts (CORE) grant program coordinates research funding initiatives across the subspecialties of otolaryngology-head and neck surgery. Modeled after National Institutes of Health study sections, CORE grant review processes provide comprehensive reviews of scientific proposals. The organizational structure and grant review process support grant-writing skills, attention to study design, and other components of academic maturation toward securing external grants from the National Institutes of Health or other agencies. As a learning community and a catalyst for scientific advances, CORE evaluates clinical, translational, basic science, and health services research. Amid the societal reckoning around long-standing social injustices and health inequities, an important question is to what extent CORE engenders diversity, equity, and inclusion for the otolaryngology workforce. This commentary explores CORE's track record as a stepping-stone for promoting equity and innovation in the specialty. Such insights can help maximize opportunities for cultivating diverse leaders across the career continuum

Apocrine Hidradenocarcinoma of the Scalp: A Classification Conundrum

Introduction The classification of malignant sweat gland lesions is complex. Traditionally, cutaneous sweat gland tumors have been classified by either eccrine or apocrine features. Methods A case report of a 33-year-old Hispanic man with a left scalp mass diagnosed as a malignancy of adnexal origin preoperatively is discussed. After presentation at our multidisciplinary tumor board, excision with ipsilateral neck dissection was undertaken. Results Final pathology revealed an apocrine hidradenocarcinoma. The classification and behavior of this entity are discussed in this report. Conclusion Apocrine hidradenocarcinoma can be viewed as an aggressive malignant lesion of cutaneous sweat glands on a spectrum that involves both eccrine and apoeccrine lesions

Detection of surgical margins in oral cavity cancer

Purpose of reviewThe quantity of tissue removed during an oncologic surgical procedure is not standardized and there are numerous reports of local recurrence despite histologically adequate resection margins. The oral cavity is one of the sites in the head and neck with high chances of recurrence following negative margins. To address this need, this article reviews the recent applications of Dynamic Optical Contrast Imaging (DOCI) towards both oral screening and the intraoperative evaluation of tumor margins in head and neck surgery.Recent findingsHuman ex-vivo and in-vivo trials suggest DOCI is well tolerated, low-cost, and sensitive for differentiating cancerous from normal tissues throughout the head and neck, in addition to the oral cavity. Ex-vivo imaging of OSCC specimens generated histologically verified image contrast. Furthermore, in-vivo intraoperative results demonstrate significant potential for image-guided detection and resection of oral cavity squamous cell carcinoma (OSCC).SummaryDOCI augments tissue contrast and may enable surgeons to clinically screen patients for oral cancer, make histologic evaluations in vivo with fewer unnecessary biopsies, delineate clinical margins for tumor resection, provide guidance in the choice of biopsy sites, and preserve healthy tissue to increase the postoperative functionality and quality of life of the patient

Time for a Paradigm Shift in Head and Neck Cancer Management During the COVID-19 Pandemic.

ObjectiveThe coronavirus disease 2019 (COVID-19) pandemic has caused physicians and surgeons to consider restructuring traditional cancer management paradigms. We aim to review the current evidence regarding the diagnosis and management of head and neck cancer, with an emphasis on the role of the multidisciplinary team (MDT) during a pandemic.Data sourcesCOVID-19 resources from PubMed, Google Scholar, the American Academy of Otolaryngology-Head and Neck Surgery, and the American Head and Neck Society were examined.Review methodsStudies and guidelines related to the multidisciplinary management of head and neck cancer in the COVID-19 setting were reviewed. A total of 54 studies were included. Given the continuously evolving body of literature, the sources cited include the latest statements from medical and dental societies.ResultsThe unpredictable fluctuation of hospital resources and the risk of the nosocomial spread of SARS-CoV-2 have direct effects on head and neck cancer management. Using an MDT approach to help define "essential surgery" for immediately life- or function-threatening disease processes in the context of available hospital resources will help to maximize outcomes. Early enrollment in an MDT is often critical for considering nonsurgical options to protect patients and health care workers. The role of the MDT continues after cancer treatment, if delivered, and the MDT plays an essential role in surveillance and survivorship programs in these challenging times.ConclusionHead and neck cancer management during the COVID-19 pandemic poses a unique challenge for all specialists involved. Early MDT involvement is important to maximize patient outcomes and satisfaction in the context of public and community safety

Decontamination Methods for Reuse of Filtering Facepiece Respirators

ImportanceThe novel coronavirus disease 2019 (COVID-19) has proven to be highly infectious, putting health care professionals around the world at increased risk. Furthermore, there are widespread shortages of necessary personal protective equipment (PPE) for these individuals. Filtering facepiece respirators, such as the N95 respirator, intended for single use, can be reused in times of need. We explore the evidence for decontamination or sterilization of N95 respirators for health care systems seeking to conserve PPE while maintaining the health of their workforce.ObservationsThe filtration properties and fit of N95 respirators must be preserved to function adequately over multiple uses. Studies have shown that chemical sterilization using soap and water, alcohols, and bleach render the respirator nonfunctional. Decontamination with microwave heat and high dry heat also result in degradation of respirator material. UV light, steam, low-dry heat, and commercial sterilization methods with ethylene oxide or vaporized hydrogen peroxide appear to be viable options for successful decontamination. Furthermore, since the surface viability of the novel coronavirus is presumed to be 72 hours, rotating N95 respirator use and allowing time decontamination of the respirators is also a reasonable option. We describe a protocol and best practice recommendations for redoffing decontaminated N95 and rotating N95 respirator use.Conclusions and relevanceCOVID-19 presents a high risk for health care professionals, particularly otolaryngologists, owing to the nature of viral transmission, including possible airborne transmission and high viral load in the upper respiratory tract. Proper PPE is effective when used correctly, but in times of scarce resources, institutions may turn to alternative methods of preserving and reusing filtering facepiece respirators. Based on studies conducted on the decontamination of N95 respirators after prior outbreaks, there are several options for institutions to consider for both immediate and large-scale implementation

Rapid Diagnostic Test Kit for Point-of-Care Cerebrospinal Fluid Leak Detection

Cerebrospinal fluid (CSF) leaks can occur when there is communication between the intracranial cavities and the external environment. They are a common and serious complication of numerous procedures in otolaryngology, and if not treated, persistent leaks can increase a patient's risk of developing life-threatening complications such as meningitis. As it is not uncommon for patients to exhibit increased secretions postoperatively, distinguishing normal secretions from those containing CSF can be difficult. Currently, there are no proven, available tests that allow a medical provider concerned about a CSF leak to inexpensively, rapidly, and noninvasively rule out the presence of a leak. The gold standard laboratory-based test requires that a sample be sent to a tertiary site for analysis, where days to weeks may pass before results return. To address this, our group recently developed a semiquantitative, barcode-style lateral-flow immunoassay (LFA) for the quantification of the beta-trace protein, which has been reported to be an indicator of the presence of CSF leaks. In the work presented here, we created a rapid diagnostic test kit composed of our LFA, a collection swab, dilution buffers, disposable pipettes, and instructions. Validation studies demonstrated excellent predictive capabilities of this kit in distinguishing between clinical specimens containing CSF and those that did not. Our diagnostic kit for CSF leak detection can be operated by an untrained user, does not require any external equipment, and can be performed in approximately 20 min, making it well suited for use at the point of care. This kit has the potential to transform patient outcomes

Point‐of‐Care Cerebrospinal Fluid Detection

ObjectiveA cerebrospinal fluid leak is one of the most serious complications in otolaryngology. It may occur as a result of injury to the skull base, typically traumatic or iatrogenic. While the presence of a leak is often discerned in the emergent setting, distinguishing normal secretions from those containing cerebrospinal fluid can be difficult during postoperative visits in the clinic. As most current laboratory-based assays are labor intensive and require several days to result, we aim to develop a more user-friendly and rapid point-of-care cerebrospinal fluid detection device.Study designOur laboratory developed a barcode-style lateral-flow immunoassay utilizing antibodies for beta-trace protein, a protein abundant in and specific for cerebrospinal fluid, with a concentration of 1.3 mg/L delineating a positive result.SettingTertiary medical center.Subjects and methodsTests with known concentrations of resuspended beta-trace protein and the contents of discarded lumbar drains (presumed to contain cerebrospinal fluid) were performed to validate our novel device.ResultsOur results demonstrate the ability of our device to semiquantitatively identify concentrations of beta-trace protein from 0.3-90 mg/L, which is within the required range to diagnose a leak, thus making beta-trace protein an excellent target for rapid clinical detection.ConclusionHerein we detail the creation and initial validation of the first point-of-care cerebrospinal fluid detection device. This device is a feasible method to more efficiently and cost-effectively identify cerebrospinal fluid leaks, minimize costs, and improve patient outcomes
