Fibrinogen and homocysteine (HCY) are molecules known to play a role in vascular homeostasis, and their blood levels are often elevated in patients with metabolic syndrome. Recent evidence suggests that sudden sensorineural hearing loss (SSHL) may have a vascular origin. This has led many authors to advocate that fibrinogen, homocysteine, and metabolic syndrome (MetS) may play a direct role in SSHL. The aim of this brief review is to examine the role and influence of these molecules and MetS on the mechanisms of SSHL. Elevated fibrinogen levels have been associated with a worse prognosis in SSHL, possibly due to increased blood viscosity and decreased blood flow. Similarly, HCY has been associated with vascular damage, particularly in hyperhomocysteinemia, although the exact association with SSHL remains controversial. MetS has been demonstrated to function both as a causative factor and as a contributor to poorer recovery in cases of SSHL. However, although some studies suggest a possible role for these biomarkers and MetS in the prognosis and treatment of SSHL, specific therapeutic and preventive strategies based solely on these factors have yet to be developed. Given their potential role in prognosis and treatment and the global epidemic of metabolic syndrome, this issue needs to be analyzed comprehensively. Thus, further quality studies need to be conducted, even though it is difficult to determine the actual impact of MetS on the development of SSHL, as it is a multifactorial disease affecting multiple organs.
Vertigo and dizziness are among the most common medical complaints, affecting an estimated 15%–30% of the adult population, increasing in frequency with age, and causing disability with high social costs. Over the years, the range of vestibular rehabilitation (VR) techniques available to patients has expanded from the 1940s, when Cawthorne and Cooksey observed that subjects with vestibular injuries tended to do better with exercises aimed at promoting eye and head movements in a graded manner, to today with the increasingly widespread use of virtual reality. The aim of this article is to trace the most important steps in the history of VR.

Septorhinoplasty is a crucial intervention in functional and aesthetic facial surgery. Although rare and usually manageable, complications could lead to disfiguring consequences. There is no universal protocol for perioperative management in the literature. The aim of this article is to analyze the surgical complications in patients who underwent open rhinoseptoplasty and were treated in the perioperative period with the standardized protocol used in our department, in order to propose it as a standardized protocol for a more global application. Methods: The patients included underwent rhinoplasty between 2017 and 2022 and were managed with the same treatment protocol. Perioperative and intraoperative data, as well as possible complications, were collected. Results: A total of 129 patients were included, 73% of which reported either mild or no complications. Abnormal scar healing was the most frequent complaint (9%), followed by edema (6.2%), nasal dyspnea (3.9%), infection (2.3%), and bleeding (2.3%). No severe complications were reported. Conclusions: Our protocol appears to be effective in minimizing complications such as infection and bleeding, although it is very difficult to compare the results with the literature.

The olfactory neuroepithelium (ON) collected with nasal swabs (NS) is a valuable source for studying brain processes in physiological and pathological conditions, due to its anatomical proximity to the brain and heterogeneous neural cell population. In this proof-of-concept study, we developed a protocol for co-culturing distinct cellular populations from ON, establishing a human olfactory neuroepithelium cell culture (hON) model from healthy individuals (HIs) without differentiation factors. We characterized the cellular composition of ON samples at harvesting, identifying sustentacular cells (Pan-CK+), neuronal cells (PGP9.5+), and ciliated respiratory cells (βIV-tubulin+) by immunofluorescence and flow cytometry. We assessed the expression and distribution of TDP-43, Tau, and α-synuclein, together with their phosphorylated isoforms, to establish a physiological reference profile. Furthermore, Seeding Amplification Assay (SAA) analysis, including disease-positive and healthy control cohorts, confirmed the absence of aggregated protein species in HIs. While p-Tau and p-α-syn localization was preserved between collection and culture, p-TDP-43 displayed neuron-specific nuclear redistribution upon culture, suggesting distinct regulatory dynamics. Longitudinal monitoring revealed that hON cultures maintain a stable neuronal population for up to 21 days, after which cells transition toward a fibroblast-like phenotype. This study establishes NS-derived hON as a feasible model for investigating neurodegenerative mechanisms, providing a baseline for disease comparisons.
