Hearing and Ageing.

Age-related hearing loss (ARHL), or presbycusis, occurs in most mammals, humans included, with a different age of onset and magnitude of loss. It is associated with two major symptoms: loss of sensitivity to sound, especially for high pitches, and a reduced ability to understand speech in background noise. This phenomenon involves both the peripheral structures of the inner ear and the central acoustic pathways.

Global and local brain connectivity changes associated with sudden unilateral sensorineural hearing loss.

Recent studies suggest that even moderate sudden sensorineural hearing loss (SSNHL) causes reduction of gray matter volume in the primary auditory cortex, diminishing its ability to react to sound stimulation, as well as reorganization of functional brain networks. We employed resting-state functional MRI (rs-fMRI), in conjunction with graph-theoretical analysis and a newly developed functional "disruption index," to study whole-brain as well as local functional changes in patients with unilateral SSNHL. We also assessed the potential of graph-theoretical measures as biomarkers of disease, in terms of their relationship to clinically relevant audiological parameters.

Global and local reorganization of brain network connectivity in sudden sensorineural hearing loss.

Recent reports suggested that even moderate sudden sensorineural hearing loss (SSNHL) can be partly responsible for a loss of gray matter volume in the primary auditory cortex, hence reducing the capacity of the auditory cortical areas to react to sound stimulation. There is also evidence for a plastic reorganization of brain functional networks visible as enhanced local functional connectivity. The aim of this study was to use rs-fMRI, in conjunction with graph- theoretical analysis and a newly developed functional "disruption index" to study whole-brain as well as local functional changes in patients with acute and unilateral sensorineural hearing loss.

Cochlear Dysfunction Is a Frequent Feature of Facioscapulohumeral Muscular Dystrophy Type 1 (FSHD1).

Introduction: Facioscapulohumeral muscular dystrophy type 1 (FSHD) represents one of the most common forms of muscular hereditary diseases and it is characterized by a great clinical variability with the typical muscular symptoms and other clinical features, including hearing impairment. However, etiopathogenetic mechanisms of auditory dysfunction are still not completely understood and it has been suggested that it could be assigned to a cochlear alteration that is present even in those subjects with a normal pure tonal audiometry (PTA) examination.

Methods: We found out the cochlear function in 26 patients with molecular diagnosis of FSHD1 and in healthy controls.

HPV infection and clinical profiles in laryngeal diseases. A preliminary study.

Purpose: The study analysed the presence of HPV in samples tissue from laryngeal chronic hyperplastic inflammation, with and without pre-neoplastic potential, and from squamous cell carcinoma of the larynx. The aim of this analysis was to evaluate the presence/absence of different types of HPV and their relationship to the clinical profile of the patients studied (habit of smoking and drinking).

Methods: Sixty cases were randomly selected from patients undergoing surgical treatment of the larynx for inflammatory/ neoplastic lesions and of neck nodes.

Subclinical cochlear dysfunction in newly diagnosed relapsing-remitting multiple sclerosis.

Background: Hearing impairment in multiple sclerosis has long been considered a process mainly related to the central auditory system. However, increasing evidence also suggests a peripheral involvement of the inner ear. The objective of this study was to investigate subclinical cochlear dysfunction and possible correlation with disease severity in untreated newly diagnosed multiple sclerosis patients using transient-evoked and distortion-product otoacoustic emissions.

Pisa Syndrome in Parkinson's Disease: Evidence for Bilateral Vestibulospinal Dysfunction.

Introduction: Pisa syndrome (PS) is a postural complication of Parkinson's disease (PD). Yet, its pathophysiology remains unclear, although a multifactorial component is probable. Cervical vestibular evoked myogenic potentials (cVEMPs) explore vestibulospinal pathway, but they have not been measured yet in PD patients with PS (PDPS) to assess a potential vestibular impairment.

The role of intraoperative stroke volume variation on bleeding during functional endoscopic sinus surgery.

Background: Functional endoscopic sinus surgery (FESS) is a minimally-invasive surgical technique for patients with paranasal sinus pathology. Surgical bleeding reduces operative field visibility and increases the incidence of serious complications. Epinephrine injection into the nasal mucosa and controlled hypotension are used to minimize bleeding.

An investigation of hearing impairment in de-novo Parkinson's disease patients: A preliminary study.

Objective: To investigate the peripheral auditory pathway in Parkinson's disease (PD) by using objective, quantitative and non-invasive audiological techniques, transient-evoked (TEOAE) and distortion product (DPOAE) otoacoustic emissions, in order to detect subclinical alterations of cochlear functioning and possible changes after dopaminergic stimulation.

Methods: We enrolled 11 untreated de-novo PD patients and 11 age and sex-matched healthy controls. Subjects underwent a routine audiological evaluation and otoacoustic emission recordings.

A survey of the nature of trauma of post-traumatic benign paroxysmal positional vertigo.

Objective: A clinical description of post-traumatic benign paroxysmal positional vertigo (t-BPPV) in a large cohort is reported, sometimes caused by apparently insignificant minor head traumas. The aim of the study was to carefully assess the prevalence of t-BPPV and the main outcomes belonging to specific traumatic events.

Design: Retrospective analysis of medical records of t-BPPV cases among patients suffering from BPPV.

Surgical management of rhinosinusitis in onco-hematological patients.

Objectives: In onco-hematological diseases, the incidence of paranasal sinuses infection dramatically increase and requires a combination of medical and surgical therapy. Balloon dilatation surgery (DS) is a minimally invasive, tissue preserving procedure. The study evaluates the results of DS for rhinosinusitis in immunocompromised patients.

Great auricular nerve preservation in parotid surgery: rationale and long-term results insights.

Great auricular nerve (GAN) is frequently sacrificed during parotid surgery. GAN preservation during parotidectomy is advised to avoid complications such as sensitive disorders, but debate still exists. In this study, our experience is reported on the matter.

Unusual postrhinoplasty complication: nasal dorsum cyst.

AMONG ALL THE POSSIBLE COMPLICATIONS OF AESTHETIC RHINOPLASTY, A RARE ONE IS THE DEVELOPMENT OF CYSTIC MASSES ON THE NASAL DORSUM: several theories suggest that cysts develop commonly by entrapment of nasal mucosa in the subcutaneous space, but they can also originate from foreign body reactions. This report deals with two cases of nasal dorsum cysts with different pathogenesis: both patients had undergone aesthetic rhinoplasty in the past (26 years ago and 14 years ago, resp.).
