Intratympanic treatment with dexamethasone as first-line or salvage therapy in sudden sensorineural hearing loss: Results of a retrospective study

2014

Aim: Sudden sensorineural hearing loss is a condition of emergency in Otolaryngology. Although there is no universally accepted treatment protocol, corticosteroids, intravenous and oral, are the most common treatment The purpose of this study is to evaluate the efficacy of intratympanic administration of dexamethasone as first line therapy, or as a rescue therapy after treatment with systemic steroids in patients not responders. Methods: The population, consisting of 85 patients referred to our unit from January 2010 to December 2013, was divided into two groups according to the treatment protocol performed. We also analyzed possible variables that may affect the response to treatment such …

Fat plug myringoplasty: Analysis of a safe procedure for small tympanic perforations

2015

Objective: Assessment of value of fat plug myringoplasty as office-based procedure in small tympanic membrane perforations. Material and Methods: Prospective study of consecutive patients undergoing fat plug myringoplasty under local anesthesia. Minimum follow-up considered was 6 months, which included several microscopic examinations. All data were recorded and analyzed statistically. Results: 33 patients matched the inclusion criteria; the mean perforation size was 2.8 mm. No change in PTA was noted after surgery in the whole series. Recurrence of perforation was detected in 7 cases (21%), which was statistically related with the cause of perforation rather than location or size (p-value …

FOLLOW-UP AFTER PEDIATRIC MYRINGOPLASTY: OUTCOME AT 5 YEARS

2014

Aim. The aim of this paper was to evaluate anatomical and functional outcomes 5 years after myringoplasty in children affected by perforated eardrum. To analyze the main differences in the frequency of postoperative complications between patients under and over 9 years of age. Methods. One hundred and thirty-two children, aged from 4 to 15 years, who underwent myringoplasty with or without mastoidectomy, were followed for a five-year period after surgery. The cohort was divided in two groups: children from 4 to 9 years old (G1) and patients older than 9 years (G2); all subjects underwent a pre- and post-operatively clinical exam and were evaluated through audiometry and impedenzometry.

The digital outcry: What incites participation behavior in an online firestorm?

2017

Brands, celebrities, or politicians are increasingly facing enormous online outrages in response to moral misconducts. These online firestorms are characterized by high message volume, indignant tonality, and negative opinion climate. Based on the concept of moral panics, this article analyzes why people join online firestorms. We argue that participation behavior is driven by a moral compass and a desire for social recognition. Results of an experiment and a content analysis of user comments show that a higher number of participants decreases users’ willingness to participate but fosters compliance with the prevalent opinion and tonality of the comments. We also observe that a higher mora…

A new species of Agrostis (Gramineae) in the A. alpina complex

2000

Abstract A new species of Agrostis L. ( A. barceloi ) is described from the northern mountains of Mallorca (Balearic Islands). The new taxon belongs to sect. Agrostis and is mainly related to A. alpina Scop. and A. schleicheri Jord. & Verl. on morphological grounds. However, A. barceloi differs from A. alpina by its narrowly-lanceolate inflorescence, with panicle branches erect during and after anthesis, non-scabrid leaves, and by smaller lemmas and others. The new species is distinguished from A. schleicheri by the smaller spikelets, lemma, palea, and anthers. In addition, A. barceloi is tetraploid (2 n =28), and differs cytologically from the diploid A. alpina (2 n =14) and the hexaploid …

Zinc accumulation in the telencephalon of lizards.

1987

The zinc concentration in the brains of two species of lizard was determined by atomic-absorption spectrophotometry. The zinc concentration was found to be highest in the telencephalon of Lacerta galloti (21.1 micrograms/g fresh weight) and Podarcis hispanica (16.77 +/- 0.8 micrograms/g) while the mesencephalon and brain stem exhibited lower zinc concentrations, i.e., 7.0 micrograms/g in Lacerta galloti and 6.08 +/- 0.4 micrograms/g in Podarcis hispanica. This high telencephalic concentration of zinc is paralleled by intense and well-defined Timm reactivity used for demonstrating the presence of zinc-containing boutons at the light-microscope level. Volumetric-densitometric studies of these…

CRMP-4 expression in the adult cerebral cortex and other telencephalic areas of the lizard Podarcis hispanica.

2002

The control of neuritogenesis is crucial for the development, maturation and regeneration of the nervous system. The collapsin response-mediated protein 4 (CRMP-4) is a member of a family of proteins that are involved in neuronal differentiation and axonal outgrowth. In rodents, this protein is expressed in recently generated neurons such as some granule neurons of the dentate gyrus, as well as in certain differentiated neurons undergoing neurite outgrowth or synaptogenesis during adulthood. Since CRMP-4 protein appears to be highly conserved throughout the evolutionary scale, we have used immunocytochemistry to study its distribution in the lizard cerebral cortex. We have found pronounced …

Augmented reality based middle and inner ear surgical procedures

2020

Otologic procedures involve manipulation of small, delicate and complex structures in the temporal bone anatomy which are in close proxmity of critical nerves and blood vessels. Augmented reality (AR) can highly benefit the otological domain by providing supplementary anatomical and navigational information unified on a single display. However, despite being composed of mainly rigid bony structures, the awareness and acceptance of possibilities of AR systems in otology is fairly low. This project aims at developing video-based AR solutions for middle and inner ear surgical procedures.We propose two applications of AR in this regard. In the first application, information about middle ear cle…

Augmented Reality in minimally invasive otologic surgery and transmodiolar cochlear implantation

2021

Optimal exposure is necessary for minimally invasive otologic surgery. Augmented reality allows to enrich the real environment by adding data without replacing it by a virtual environment and to view this information on a single screen by combining the vision of the operating field and the imaging. This technique is very little described in otology in the literature. This project aims to develop augmented reality solutions for otological surgeries and transmodiolar implantation. To prepare this augmented reality project, we studied the visualization of the middle ear by a virtual endoscope based on preoperative high resolution CT-scans. Then, we worked on the application of augmented realit…
