(1) Background: Chronic rhinosinusitis with nasal polyps (CRSwNP) has a high rate of recurrence in patients, despite therapy with local corticosteroids and functional endoscopic sinus surgery. Dupilumab, a recombinant monoclonal human IgG4 antibody directed against the IL-4 receptor α that inhibits both IL-4 and IL-13 signal transduction, is available for symptomatic therapy. Patient preference between repeated surgery and injection therapy with Dupilumab is not known.

Background: Nonsteroidal anti-inflammatory drug (NSAID)-exacerbated respiratory disease (N-ERD) comprises the triad of chronic rhinosinusitis with nasal polyps, asthma and intolerance to NSAIDs. Dupilumab treatment, targeting the interleukin-4 (IL-4) receptor α, significantly reduces polyp burden as well as asthma symptoms. Here we aimed to investigate the effect of dupilumab on aspirin intolerance, burden of disease and nasal cytokine profiles in patients with N-ERD.

Objectives: Olfactory dysfunction (OD) constitutes a major symptom in Coronavirus Disease 2019 (COVID-19). Yet, most data on smell loss rely on the evaluation of orthonasal olfactory performance. Therefore, we aimed to assess retronasal olfactory function (ROF) over a period of several weeks in proven and suspected COVID-19 patients.

Oral tongue squamous cell carcinomas (OTSCCs) have an increasing incidence in young patients, and many have an aggressive course of disease. The objective of this study was to identify candidate prognostic protein markers associated with early-onset OTSCC. We performed an exploratory screening for differential protein expression in younger (≤45 years) versus older (>45 years) OTSCC patients in The Cancer Genome Atlas (TCGA) cohort ( = 97).

Article Synopsis
  • More than half of autosomal recessive genetic hearing loss cases in Austria are linked to mutations in a single gene, while no specific gene has been identified for autosomal dominant cases.
  • Diagnostic testing on families with autosomal dominant hearing loss revealed candidate variants in the MYO6 gene, including three novel mutations.
  • The findings indicate a high prevalence of MYO6 variants in Austrian patients, stressing the importance of multiple genetic factors for accurate genetic counseling and personalized treatment approaches.

Background: Corona Virus Disease 2019 (COVID-19) emerged in December 2019 and rapidly spread globally. Since there is still no specific treatment available, prevention of disease spread is crucial to manage the pandemic. Adequate public information is very important.

Background: Adenotonsillectomy is one of the most common pediatric surgical procedures. Postoperative voice changes are a very common concern among patient's parents. Therefore, the aim of this study is to analyze acoustic voice parameters after adenotonsillectomy, tonsillectomy, and adenoidectomy in pediatric patients in a tertiary referral academic center.

Article Synopsis
  • Acute laryngitis is mostly caused by viral infections and often doesn't require professional medical attention, yet it leads to significant hoarseness that affects daily life, prompting increased online searches during winter months.
  • The study analyzed Google Trends data from various countries between 2004 and 2019 to understand how people search for laryngitis information, taking into account both English and non-English speaking nations.
  • Findings revealed that search interest peaked in winter across all countries studied, highlighting the need for improved web-based health education to combat misinformation and enhance public health literacy.

Clinical tests assessing olfactory performance have become indispensable for diagnosing olfactory dysfunction. As time and personnel resources are limited, it would be advantageous to have shorter protocols focusing on singular aspects of olfactory performance, such as odor identification. However, such a unidimensional approach is often inconclusive and needs further tests (and tools).

Chronic rhinosinusitis (CRS) is a common disease that substantially impairs the quality of life (QoL). Here, we aimed to assess patients' QoL in different subtypes of CRS and correlated this with nasal polyp size to improve the clinical understanding of the burden of disease. In this retrospective single-center study, 107 patients with the following diagnoses were analyzed: CRS without nasal polyps (CRSsNP), CRS with nasal polyps (CRSwNP), or aspirin-exacerbated respiratory disease (AERD).

Purpose: Epistaxis represents the most frequent ear, nose, throat-related emergency symptom. Seasonal variation in epistaxis incidence, with peaks during winter months, is widely accepted, although the literature itself remains inconclusive. The objective of this study was to evaluate public inquiry into nose bleeding, by considering Google-based search query frequency on "Epistaxis"-related search terms and to assess possible seasonal variations globally.

Objectives: The human sense of smell constitutes the main part of flavor perception. Typically, patients with loss of olfactory function complain of diminished perception during eating and drinking. However, some patients with smell loss still report normal enjoyment of foods.

Objectives: Neurodegenerative diseases can alter odor memory in addition to inducing quantitative impairment, and olfactory memory can be tested using the validated olfactory memory test with encapsulated odors (Odor Discrimination Memory Test [ODMT]). The aim of this study was to investigate the new Sniffin' Sticks ODMT (SSODMT), which is comparable with the ODMT.

Methods: The SSODMT was administered to 48 subjects (30 women, 18 men; mean age, 34.
