Acute mastoiditis: 30 years review in a tertiary hospital.

Objective: Acute mastoiditis, the most common complication of acute otitis media, is approached in our study, focused on children from the Autonomous Community of Cantabria, Spain. The aim is to analyze its clinical-epidemiological characteristics and propose diagnostic and treatment recommendations.

Study Design/setting: We conducted a 30-year retrospective study on patients under 18 years of age diagnosed with acute mastoiditis in Cantabria.

Sensorineural Hearing Loss in Patients With the m.1555A>G Mutation in the MTRNR1 Gene.

Objective: Mutations in the MTRNR1 gene of mitochondrial DNA are associated with non-syndromic hearing loss and increased susceptibility to aminoglycoside ototoxicity. The aim of our study was to determine the clinical characteristics of sensorineural hearing loss caused by the m.1555A>G mutation in MTRNR1.

Hearing loss secondary to variants in the OTOF gene.

Objective: Genetic variants in the OTOF gene are responsible for non-syndromic hearing loss with an autosomal recessive inheritance pattern. The objective of our work was to evaluate the clinical characteristics of patients with biallelic pathogenic variants in OTOF and their evolution after treatment.

Methods: A cohort of 124 patients with prelingual hearing loss, studied from 1996 to 2023, was included in this study.

Novel Cases of Non-Syndromic Hearing Impairment Caused by Pathogenic Variants in Genes Encoding Mitochondrial Aminoacyl-tRNA Synthetases.

Dysfunction of some mitochondrial aminoacyl-tRNA synthetases (encoded by the , , and genes) results in a great variety of phenotypes ranging from non-syndromic hearing impairment (NSHI) to very complex syndromes, with a predominance of neurological signs. The diversity of roles that are played by these moonlighting enzymes and the fact that most pathogenic variants are missense and affect different domains of these proteins in diverse compound heterozygous combinations make it difficult to establish genotype-phenotype correlations. We used a targeted gene-sequencing panel to investigate the presence of pathogenic variants in those four genes in cohorts of 175 Spanish and 18 Colombian familial cases with non-DFNB1 autosomal recessive NSHI.

Sudden hearing loss secondary to syphilis.

Background: Syphilis is a sexually transmitted disease caused by the spirochete Treponema pallidum, whose incidence has increased significantly in recent years. Some patients may develop sudden hearing loss (SHL) against the background of otosyphilis.

Objectives: The objective of our study was to determine whether routine lues serology is useful in patients presenting with sudden hearing loss.

Sudden Hearing Loss as an Initial Symptom of Vestibular Schwannoma.

Objective: This study aims to determine the prevalence of vestibular schwannoma (VS) among patients presenting with sudden hearing loss (SHL) and to characterize the clinical features of individuals diagnosed with both VS and SHL.

Methods: We conducted an observational retrospective review at a tertiary referral center, spanning a 30-year period, focusing on patients diagnosed with SHL where VS was confirmed as the underlying cause. We included patients meeting these criteria while excluding those lacking imaging or with a pre-existing diagnosis of VS.

Otologic manifestations of IgG4-related disease.

IgG4-related disease (IgG4-RD) is a systemic autoimmune fibroinflammatory disease characterized by multiorgan infiltration of IgG4-positive plasma cells, fibrosis and vasculopathy that determine dysfunction of the affected organ. This review aims to characterize the otologic manifestations of the disease. We have conducted a systematic review of the biomedical literature published describing cases of IgG4-RD with otologic manifestations.

Clinical Impact of Genetic Diagnosis of Sensorineural Hearing Loss in Adults.

Hypothesis: Adult genetic sensorineural hearing loss (SNHL) may be underestimated.

Background: The diagnosis of genetic hearing loss is challenging, given its extreme genetic and phenotypic heterogeneity, particularly in adulthood. This study evaluated the utility of next-generation sequencing (NGS) in the etiological diagnosis of adult-onset SNHL.

Gb3/cd77 Is a Predictive Marker and Promising Therapeutic Target for Head and Neck Cancer.

Head and neck squamous cell carcinoma is the sixth leading cancer in the world. This cancer is difficult to treat and is characterized by recurrences that are often fatal. This cancer is generally removed surgically, but it often regrows from the edges of the lesion from where most recurrences reappear.

Audiovestibular Symptoms in Patients With Idiopathic Hypertrophic Pachymeningitis: Systematic Literature Review.

Background And Objective: Hypertrophic pachymeningitis is an infrequent inflammatory disease resulting in thickening and fibrosis of the dura mater. In most cases, the cause in unknown and is called idiopathic hypertrophic pachymeningitis (IHP). Audiovestibular symptoms are infrequent and the pathogenesis is still unclear.

Endoscopic endonasal surgery during COVID-19 pandemic: Management guideline.

Current SARS-CoV-2 coronavirus pandemic is challenging medical and surgical activities. Specifically, within neurosurgery, endoscopic endonasal approaches pose a high risk of contagion for healthcare personnel involved in it. Initially, the recommendation was to avoid such surgeries.

Retropharyngeal Abscess. Clinical Review of Twenty-five Years.

Introduction: Retropharyngeal abscess is a serious condition. Its rare occurrence, thus sharing symptoms with other processes, make it a diagnostic challenge for the clinician. Therefore, it is critical to make an early diagnosis to prevent delaying treatment and avoid complications.

Head and neck cancer screening in patients eligible for liver transplantation.

Introduction: Liver transplantation is the only alternative treatment in patients in end-stage liver function. In many cases the need for liver transplantation is a consequence of the toxic effects of alcohol. The aim of our study was to determine if patients who are candidates for a liver transplant require a systematic exploration of the head and neck to rule out malignant lesions in this area.
