Complications of eustachian tube balloon dilation: Manufacturer and User Facility Device Experience (MAUDE) database analysis and literature review.

Objective: To provide an analysis of complications following eustachian tube balloon dilation as well as their treatments and outcomes. Data Sources: PubMed, Ovid Embase, and MAUDE Database. Review Methods: A systematic approach following PRISMA guidelines was used to identify publications pertaining to balloon dilation of the eustachian tube from PubMed and Ovid Embase databases was used. Once these publications were critically reviewed, the primary outcome extracted were reported complications. Additional complications were collected in the Manufacturer and User Facility Device Experience (MAUDE) database using the product class "eustachian tube dilation device" and searching through relevant manufacturers. Complications and outcomes were compared between these sources. Results: Fifty five full-length manuscripts involving 7155 patients were included and 98 complications reported for a 1.4% complication rate. The most frequently reported adverse events were subcutaneous emphysema of the head and neck (19%), epistaxis (12%), and acute otitis media (11%). The MAUDE search returned 18 distinct patient entries, of which 12 (67%) reported complications. The most reported complications in the MAUDE database included subcutaneous emphysema (8, 67%) and pneumomediastinum (3, 25%). The most serious complication was a carotid artery dissection reported in one patient in the MAUDE database. Conclusion: Eustachian tube dilation is rarely associated with complications, which nevertheless may lead to morbidity and medical emergencies. Patients and providers should recognize potential risks associated with this intervention as well as methods to manage complications.

Management of Adult Inpatient Otolaryngologic Consultations During the COVID-19 Pandemic: A Proposed Tier-Based Triage System.

The coronavirus disease 2019 (COVID-19) pandemic has placed tremendous strain on health care systems, leading to unprecedented challenges and obstacles in the delivery of patient care. Otolaryngologists are frequently called on for inpatient consultations for an array of pathologies, ranging from chronic benign conditions to acutely life-threatening processes. Professional otolaryngologic societies across the world have proposed limiting patient care to time-sensitive and urgent matters; however, limited literature is available to describe how this transient change in philosophy may translate to clinical practice. Here we present a structured algorithm that allows for rapid triage of otolaryngologic consults during the ongoing pandemic, in efforts to minimize infectious spread and protect clinicians while preserving high-quality patient care. Considerations for managing these consults are presented, with a commentary on practical and ethical considerations.

Epigenetic factors and autism spectrum disorders.

Autism is a complex neurodevelopmental disorder that has significant phenotypic overlap with several diseases, many of which fall within the broader category of autism spectrum disorders (ASDs). The etiology of the disorder is unclear and seems to involve a complex interplay of polygenic as well as environmental factors. We discuss evidence that suggests that epigenetic dysregulation is highly implicated as a contributing cause of ASDs and autism. Specifically, we examine neurodevelopmental disorders that share significant phenotypic overlap with ASDs and feature the dysregulation of epigenetically modified genes including UBE3A, GABA receptor genes, and RELN. We then look at the dysregulated expression of implicated epigenetic modifiers, namely MeCP2, that yield complex and varied downstream pleiotropic effects. Finally, we examine epigenetically mediated parent-of-origin effects through which paternal gene expression dominates that of maternal contributing to contrasting phenotypes implicated in ASDs. Such preliminary evidence suggests that elucidating the complex role of epigenetic regulations involved in ASDs could prove vital in furthering our understanding of the complex etiology of autism and ASDs.
