RESUMEN

BACKGROUND: The SARS-CoV-2 virus continues to spread rapidly across the globe afflicting many with Coronavirus Disease 2019 (COVID-19). As the infection rates rise, a growing number of SARS-CoV-2 positive individuals have been reported to complain of olfactory disturbances at an alarming rate. Postviral olfactory dysfunction (PVOD) is a well-known phenomenon that may explain the olfactory dysfunction reported by SARS-CoV-2 infected individuals. METHODS: A scoping literature review was performed to identify studies that investigated the mechanisms of postviral olfactory dysfunction. Studies demonstrating pathophysiological, histological, immunochemical, and epidemiological outcomes of PVOD were included. RESULTS: Fourteen studies were included in addition to one international news article. Three studies reported destruction of the olfactory epithelium following intranasal inoculation of various viral strains in mice. Three studies isolated pathogenic, anosmia inciting viruses (Parainfluenza virus, Human Coronavirus, Rhinovirus) through nucleic acid amplification. Eleven studies demonstrated female predilection in patients with PVOD and COVID-19 associated olfactory dysfunction, of which the majority were over 50 years old. CONCLUSIONS: PVOD and COVID-19 associated olfactory dysfunction demonstrates considerable similarities in epidemiological trends and disease sequela of other viruses to suggest identical pathophysiological mechanisms. Further studies such as intranasal inoculation and histological biopsies are needed to support our hypothesis.

RESUMEN

OBJECTIVE: In response to the American Academy of Otolaryngology - Head and Neck Surgery's recommendations to limit patient care activities in the times of SARS-CoV-2, many elective surgeries have been canceled without patient clinics transitioning to virtual visits. With regulations for telemedicine loosened, new possibilities for the practice of otolaryngology have opened. To address the uncertain duration of this pandemic, a review was conducted of current literature on use of telemedicine services in the current SARS-CoV-2 pandemic and in previous national emergencies to reveal the role telemedicine can play for otolaryngology practices. DATA SOURCES: Pubmed articles with an independent search query were utilized. METHODS: Literature review performed by one author searched for all published English-language literature on telehealth in the SARS-CoV-2 era. Articles were considered for discussion if they provided relevant developments for telemedicine in the context of the SARS-CoV-2 pandemic. RESULTS: Telemedicine can be up-scaled in the current SARS-CoV-2 pandemic where exposure containment is of the utmost priority. With patient interaction possible through virtual communication, telemedicine allows continued patient care while minimizing the risk of viral spread. In the realm of otolaryngology, telemedicine has been used in the past during disasters with other studies demonstrating high diagnostic concordance with inpatient visits. Many institutions have recognized the potential for such care as they begin utilize both virtual visits and in-person care during this pandemic. CONCLUSION: To limit the spread of SARS-CoV-2, we support the AAO-HNS recommendation for the adoption of novel ways to employ telemedicine in this era. Many emergency departments and health care systems have the infrastructure necessary for synchronous video telemedicine visits that can be leveraged to provide quality care with patients. With the continued need to socially distance, telemedicine can protect both physicians and patients from unnecessary exposure to the virus.

RESUMEN

With the arrival of the coronavirus disease (SARS-CoV-2) in the United States, care practice paradigms have drastically changed. Data from China suggest that the new virus poses additional risks as case fatality of patients with cancer was higher at 5.6% compared to 2.3% of the general population. There are three proposed major strategies to address care for patients with cancer in this SARS-CoV-2 pandemic with postponing treatment for those with stable cancer, increasing personal protection provisions for patients with cancer, and increasing monitoring if a patient becomes infected with SARS-CoV-2. In this present commentary, we discuss the unique mental health challenges and burdens of patients with head and neck cancer in the times of the SARS-CoV-2 pandemic and approaches to mitigate these stressors through telemedicine to reduce future burdens to the patient and the health care system.

RESUMEN

OBJECTIVES: To examine the national rates of complications, readmission, reoperation, death and length of hospital stay after laryngectomy. To explore the risks of neck dissection with laryngectomy using outcomes. METHODS: The American College of Surgeons National Quality Improvement Program (ACS-NSQIP) database was reviewed retrospectively. The database was analyzed for patients undergoing laryngectomy with and without neck dissection. Demographic, perioperative complication, reoperation, readmission, and death variables were analyzed. RESULTS: 754 patients who underwent total laryngectomy during this time were found. Demographic analysis showed average age was 63 years old, 566 (75.1%) were white, and 598 (79.3%) were male. Of these patients, 520 (69.0%) included a neck dissection while 234 (31.0%) did not. When comparing patients who received a neck dissection to those who did not, there were no significant differences in median length of hospital stay (12.5 days w/vs. 13.3 days w/o, P = 0.99), rates of complication (40% w/vs. 35% w/o, P = 0.23), reoperation (13.5% w/vs. 14% w/o, P = 0.81), readmission (14% w/vs. 18% w/o, P = 0.27), and death (1.3% w/vs. 1.3% w/o, P > 0.99). Furthermore, neck dissection did not increase the risk of complication (P = 0.23), readmission (P = 0.27), reoperation (P = 0.81), death (P = 0.94), or lengthened hospital stay (P = 0.38). CONCLUSIONS: Concurrent neck dissection does not increase postoperative morbidity or mortality in patients undergoing total laryngectomies. These results may help physicians make decisions regarding concurrent neck dissection with total laryngectomy.

RESUMEN

Multiple sclerosis (MS) is a devastating autoimmune demyelinating disease of the central nervous system (CNS). This study investigated whether expression and activity of the calcium-activated protease calpain correlated with Th1/Th2 dysregulation in MS patients during states of relapse and remission. Calpain expression and activity were significantly increased in peripheral blood mononuclear cells (PBMCs) from MS patients, compared to controls, with the highest expression and activity noted during relapse. Th1 cytokines were highest and Th2 cytokines were lowest in MS patients during relapse. Treatment with calpain inhibitor, calpeptin, decreased Th1 cytokines in PBMCs from MS patients. Calpain inhibitor also reduced degradation of myelin basic protein (MBP) by inhibiting the calpain secreted from MBP-specific T cells. Taken together, these results suggested calpain involvement in Th1/Th2 dysregulation in MS patients.
