Otosyphilis: Two case reports and review of the English and Spanish literature of the last 24 years.

Syphilis has significantly increased its incidence in Europe and North America in the past 20 years. Although rare, sudden hearing loss might be a complication of syphilis infection. We present two cases of otosyphilis seen in our hospitals and review of the English and Spanish literature already published since 2000.

Comparison of the MIPS technique versus linear incision with tissue preservation in osseointegrated implants in the Ponto model®.

Background And Objectives: The surgery of osseointegrated implants has undergone different modifications over the years with the aim of achieving better results and facilitating the surgical technique. Today the most commonly used technique is the linear incision with tissue preservation and placement of the abutment and implant. The long-term success of this technique has served as the basis for the development of the so-called minimally invasive surgical approach (MIPS).

Enlarged vestibular aqueduct as a cause of postneonatal deafness.

Introduction: The enlarged vestibular aqueduct (EVA) is the most frequent malformation of the inner ear associated with sensorineural hearing loss (5-15%). It exists when the diameter in imaging tests is greater than 1.5 mm at its midpoint.

Universal neonatal hearing screening and delayed hearing loss or late-developmental hearing loss.

Objective: To determine the percentage of children with permanent bilateral postnatal hearing loss in order to study its incidence, related risk factors, diagnosis and treatment.

Methods: Retrospective study to collect data on children diagnosed with hearing loss outside the neonatal period in the Hearing Loss Unit of the Hospital Universitario Central de Asturias, from April 2014 to April 2021.

Results: 52 cases met the inclusion criteria.

Ototoxicity in cancer survivors: Experience and proposal of a surveillance protocol.

Introduction: Ototoxicity occurs in different percentages in patients after treatment with platinum-based chemotherapy or cranial radiation therapy. The aim of this study was to present our experience in ototoxicity monitoring.

Material And Methods: A review was made of the registry of paediatric cancer patients referred to the Children's Hearing Loss Unit from 1999 to 2019.

Introduction: Ototoxicity occurs in different percentages in patients after treatment with platinum-based chemotherapy or cranial radiation therapy. The aim of this study was to present experience in ototoxicity monitoring.

Material And Methods: A review was made of the registry of paediatric cancer patients referred to the Children's Hearing Loss Unit from 1999 to 2019.

Application of Wireless Contralateral Routing of Signal (CROS) Technology in Unilateral Cochlear Implant Users.

Introduction: Single cochlear implantation usually provides substantial speech intelligibility benefits but bilaterally deaf, unilaterally implanted subjects will continue to experience limitations due to the head shadow effect, like single-sided deaf individuals. In the treatment of individuals with single-sided deafness one option is contralateral routing of signal (CROS) devices, which constitute a non-surgical intervention of the second ear in unilaterally implanted individuals.

Method: Twelve experienced adult cochlear implant users with Naída Q70 processor and the CROS device used in combination participated in the study.

Evaluation of vaccination coverage in cochlear implant patients at a referral hospital in Northern Spain.

Background And Objective: The risk of bacterial meningitis increases in cochlear implant patients. Therefore, pneumococcal, influenza and Haemophilus influenzae type b vaccination is indicated in this group. The aim of this study was to determine compliance with the vaccination calendar in patients implanted in a referral hospital.

Vowel production in hearing impaired children: A comparison between normal-hearing, hearing-aided and cochlear-implanted children.

Introduction And Objectives: Inadequate auditory feedback in prelingually deaf children alters the articulation of consonants and vowels. The purpose of this investigation was to compare vowel production in Spanish-speaking deaf children with cochlear implantation, and with hearing-aids with normal-hearing children by means of acoustic analysis of formant frequencies and vowel space.

Methods: A total of 56 prelingually deaf children (25 with cochlear implants and 31 wearing hearing-aids) and 47 normal-hearing children participated.

Comprehensive genomic diagnosis of non-syndromic and syndromic hereditary hearing loss in Spanish patients.

Background: Sensorineural hearing loss (SNHL) is the most common sensory impairment. Comprehensive next-generation sequencing (NGS) has become the standard for the etiological diagnosis of early-onset SNHL. However, accurate selection of target genomic regions (gene panel/exome/genome), analytical performance and variant interpretation remain relevant difficulties for its clinical implementation.

[Bacterial etiology of acute otitis media in Spain in the post-pneumococcal conjugate vaccine era].

Introduction: Acute otitis media (AOM) is common in children aged <3 years. A pneumococcal conjugate vaccine (PCV) (PCV7; Prevenar, Pfizer/Wyeth, USA) has been available in Spain since 2001, which has a coverage rate of 50-60% in children aged <5 years.

Materials And Methods: Children aged ≥3 to 36 months with AOM confirmed by an ear-nose-throat specialist were enrolled at seven centers in Spain (February 2009-May 2012) (GSK study identifier: 111425).

Primary inverted papilloma of the middle ear with intracranial invasion.

Background: Primary inverted papillomas of the middle ear are extremely rare tumors, with only few cases published in the literature. They have a characteristic epithelium surface inversion to the inside of the stroma. Inverted papillomas are benign lesions but have a high propensity of recurrence, local aggressiveness, and association with malignancy.

Grisel's syndrome as a sequela of a complicated acute mastoiditis.

Grisel's syndrome is a rare complication of ENT area infections. It consists of a non-traumatic atlantoaxial subluxation after an infectious process. Its characteristic symptom is persistent torticollis despite a resolved infection.

Schwannoma of the larynx. An infrequent laryngeal tumour.

Schwannomas are benign tumours, rare among tumours of the larynx. They normally present as supraglottic masses (because they may arise from the internal branch of the superior laryngeal nerve), most commonly involving aryepiglottic folds or false vocal folds. Most patients present with a globus sensation, dysphagia or hoarseness.

Unilateral agenesis of the internal carotid artery.

Unilateral agenesis of the internal carotid artery (ICA) is an extremely rare anomaly. Diagnosis is often incidental in a radiological examination. Recognition of this anomaly has important clinical implications because other life-threatening conditions can be associated and it must be taken into account when planning carotid surgery.

[Surgical treatment of vagal paragangliomas].

Vagal paragangliomas are much less frequent than carotid and jugulo-tympanic paragangliomas and, like these other forms, can be sporadic or familial. The familial forms usually occur as isolated tumors or within syndromic entities such as multiple endocrine neoplasia type IIA-B, Von Hippel- Lindau syndrome and neurofibromatosis type 1. The genes causing the disease are located in three loci: SDHD (11q23), SDHC (1q21) and SDHB (1p36.
